The tank 110 has a slurry inlet 111 at one side for inflow (or input) of slurry to be thickened. The mud described herein may be a mixture of mud and water produced during the washing of the sand by the movable dewatering screen 10. The slurry inlet 111 is located at one side of the tank 110, and may be implemented by connecting the slurry inlet 111 to one side of the tank 110 in a separate structure form such as a pipe shape, a groove shape, etc., or may be provided according to the structure of the tank 110 itself. For example, in one embodiment, the top edge of one side of the tank 110 can be used as the slurry inlet 111 without additional provision. In another embodiment, a recess is provided in the top of one side of the tank 110 to serve as the slurry inlet 111. In yet another embodiment, a hole is provided on one side of the tank 110 to serve as a slurry inlet 111. Further, the slurry inlet 111 may be located at an upper portion, a middle portion, a lower portion, etc. of one side of the tank 110, and may be disposed according to actual needs.

The other side of the tank 110 has an overflow port 112 for discharging (or discharging) the overflow liquid from the upper layer generated by the slurry concentration. The overflow port 112 is located at the other side of the box body 110, and the overflow port 112 may be connected to the other side of the box body 110 in an independent structure form such as a tubular shape, a groove shape, etc., or may be provided according to the structure of the box body 110 itself. For example, in one embodiment, the top edge of the other side of the tank 110 can be used as the overflow port 112 without additional provision. In another embodiment, a notch is formed on the top of the other side of the box 110 to serve as the overflow port 112. In yet another embodiment, a hole is provided on one side of the tank 110 to serve as the overflow port 112. Further, the overflow port 112 may be located at an upper portion, a middle portion, a lower portion, and the like of the other side of the box body 110, and may be set according to actual needs.

The partition 120 is vertically disposed in the case 110, and the partition 120 may be connected to the case 110 or not, if the connection is integrally formed or detachably connected. The material of the spacer 120 may be a metal or non-metal material such as iron, copper, aluminum, rubber, plastic, glass, etc., and may be selected according to the properties of the slurry to be processed. The baffle 120 may be disposed in the tank 110 between the slurry inlet 111 and the overflow 112, and one or more pieces may be disposed to form at least one U-shaped flow channel in one tank 110. The shape of the spacer 120 is not limited to the planar straight plate shown in fig. 5. For example, in one embodiment, the partition 120 may be a T-shaped partition, which may be comprised of a top plate and a riser vertically disposed within the case 110. The top plate of the T-shaped partition forms a shield at the top of the slurry inlet 111 and the overflow port 112, and thus can play a certain role in guiding and preventing splashing when the fluid flows in or is discharged. In one embodiment, the T-shaped partition can be connected with other members through a top plate, so as to fix the T-shaped partition or the concentrating device 100. In another embodiment, the baffle 120 may be a corrugated baffle to further increase the contact area with the slurry. In yet another embodiment, the baffle 120 may be a dashed-line baffle.

The shape of the cross-section of the cone 130 as shown in fig. 5 may be adapted to the shape of the cross-section of the bottom surface of the case 110 so that it can be coupled to the bottom of the case 110. The cone 130 is used to collect thickened mud, which is herein described as solids or slurry that is typically settled at the bottom of the thickener after the mud has been thickened by settling, and may also be referred to as underflow. Since the cone 130 has an inclined surface, the concentrated slurry sinks to the bottom of the cone 130 along the shape of the cone 130 for collection. The bottom of the cone 130 is also connected with an underflow pipe 140, the underflow pipe 140 is also connected with an underflow discharge valve 150, and the opening and closing of the underflow pipe 140 are controlled by the underflow discharge valve 150, so that whether the concentrated mud is discharged or not can be controlled. In one embodiment, the underflow discharge valve 150 may also control the flow rate, pressure, etc. of the fluid in the underflow pipe 140, thereby controlling the discharge rate of the thickened mud, etc.

The concentration device 100 shown in fig. 5 is disposed on a second movable chassis 200, and the second movable chassis 200 can move the concentration device 100, thereby implementing the movable thickener of the present invention. The concentrator device 100 may be directly or indirectly connected to the second movable chassis 200. For example, the concentration device 100 may be fixed or detachably connected to the second movable chassis 200 by welding, clipping, screwing, or mounting, or may be directly placed on the second movable chassis 200. In one embodiment, the thickening apparatus 100 may be disposed on the second movable chassis 200 by a bracket. The position where the concentration device 100 is disposed on the second movable chassis 200 may not be limited to the manner of contacting the second movable chassis 200 through the underflow pipe 140 shown in fig. 5, but may be disposed on the second movable chassis 200 through other components of the concentration device 100. In one embodiment, the cone 130 of the thickening apparatus 100 is connected to the second movable chassis 200, thereby enabling the thickening apparatus 100 to be disposed on the second movable chassis 200. In another embodiment, the tank 110 of the concentration device 100 is connected to the second movable chassis 200, thereby allowing the concentration device 100 to be disposed on the second movable chassis 200. Implementations of the second movable chassis 200 may include a variety, for example in one embodiment, the second movable chassis 200 may be a tracked movable chassis. In another embodiment, the second movable chassis 200 may be a wheeled movable chassis.

While the embodiments and implementations of the mobile thickener of the present invention have been described with reference to fig. 5, it will be understood by those skilled in the art that the structure of the mobile thickener shown in fig. 5 is illustrative and not limiting, and those skilled in the art can make modifications to the structure of the thickener according to the present invention as needed and desired under the teachings of the present disclosure and still be within the scope of the present invention. For example, with respect to the placement of the slurry inlet or overflow, in one embodiment, a flapper can be placed on the tank 110 at a location where the slurry inlet or overflow is located, which flapper opens (or lifts) to expose the slurry inlet or overflow and closes (or drops) the slurry inlet or overflow. For example, more or less may be provided as desired with respect to the number of partitions. The structure of the baffle can be adjusted as required. For example, the number of the concentration devices 100 may not be limited to one shown in fig. 5, and may be arranged in plural, and the arrangement of the plurality of concentration devices 100 may include various, and a stepped arrangement of the plurality of concentration devices 100 will be described below with reference to fig. 6. Fig. 6 is a schematic top view showing a movable type thickener including a multi-stage thickener set according to an embodiment of the present invention.

According to one embodiment of the invention, the mobile thickener may comprise a plurality of thickener sets, and the slurry inlet of the thickener in the next thickener set in adjacent two stages is connected to the overflow of the thickener in the previous thickener set, wherein at least one thickener may be included in each thickener set. The movable thickener comprises a movable chassis and a multi-stage concentration device group consisting of a plurality of concentration devices, wherein the multi-stage concentration device group is arranged on the movable chassis. As will be exemplified below in connection with fig. 6. To facilitate viewing of the arrangement of the multi-stage concentrator group, fig. 6 is a top view showing the multi-stage concentrator group. As shown in fig. 6, the mobile thickener includes a multi-stage thickener set and a second mobile chassis (not shown), wherein the multi-stage thickener set may include a primary thickener set L1 (shown by a dotted line frame), a secondary thickener set L2 (shown by a dotted line frame), a tertiary thickener set L3 (shown by a dotted line frame), and the like; wherein each stage of concentration plant group may comprise one or more concentration plants according to the present invention, for example, the illustrated first stage concentration plant group L1 comprises concentration plants 100-11 and concentration plants 100-12, etc., the second stage concentration plant group L2 comprises concentration plants 100-21 and concentration plants 100-22, etc., and the third stage concentration plant group L3 comprises concentration plants 100-31 and concentration plants 100-32, etc.

The structures of the concentration devices 100-11, 100-12, 100-21, 100-22, 100-31, 100-32, etc. are the same as or similar to the structure of the concentration device shown in fig. 5, and thus, the description thereof is omitted. However, in order to facilitate the observation of the corresponding parts of the concentrating device in the top view shown in fig. 6, the following description will be made by way of example only with respect to the concentrating devices 100-11 and 100-12. The thickening apparatus 100-11 may include a tank 110-11 having a slurry inlet 111-11 on one side of the tank 110-11 and an overflow 112-11 on the other side of the tank 110-11, a baffle 120-11, a cone 130-11, an underflow pipe (not shown), and an underflow discharge valve (not shown). The box 110-11 may be a hollow cylinder and the cone 130-11 may be a cone. The thickening apparatus 100-12 may include a tank 110-12 having a slurry inlet 111-12 on one side of the tank 110-12 and an overflow 112-12 on the other side of the tank 110-12, a baffle 120-12, a cone 130-12, an underflow pipe (not shown), and an underflow discharge valve (not shown). The housing 110-12 may be a hollow cylinder and the cone 130-12 may be a cone.

As shown in fig. 6, the slurry inlets 111-21, 111-22 of the thickeners 100-21, 100-22 in the next-stage thickener set (e.g., the second-stage thickener set L2) in the adjacent two stages (e.g., the first-stage thickener set L1 and the second-stage thickener set L2) are connected to the overflow ports 112-11, 112-12 of the thickeners 100-11, 100-12 in the previous-stage thickener set (e.g., the first-stage thickener set L1) in the adjacent two stages (e.g., the first-stage thickener set L1 and the second-stage thickener set L2). Furthermore, the second-stage concentrator group L2 and the third-stage concentrator group L3 are also adjacent two stages, and therefore the slurry inlets 111-31, 111-32 of the concentrators 100-31, 100-32 of the third-stage concentrator group L3 (i.e., the next-stage concentrator group) in the second-stage concentrator group L2 and the third-stage concentrator group L3 are connected to the overflow ports 112-21, 112-22 of the concentrators 100-21, 100-22 of the second-stage concentrator group L2 (i.e., the previous-stage concentrator group). The overflow ports 112-31, 112-32 of the concentration devices 100-31, 100-32 of the third-stage concentration device group L3 can be connected with the slurry inlet of the concentration device of the next-stage concentration device group; if it has no next-stage concentrator group, the overflow ports 112-31, 112-32 can be used as the total overflow port of the whole thickener for the outflow of the final overflow liquid. Similarly, the slurry inlets 111-11, 111-12 of the thickeners 100-11, 100-12 of the primary set of thickeners L1 may be connected to the overflow of the thickener of the primary set of thickeners above it; if it does not have a previous concentrator group, the slurry inlets 111-11, 111-12 can be used as a total slurry inlet for the entire thickener for the input of the slurry to be treated. According to the arrangement, the slurry to be treated can flow in from the slurry inlet of the first-stage concentration device group L1, passes through the multiple thickening of the multi-stage concentration device group, the concentrated slurry is discharged from the underflow pipe of each stage concentration device group, and the obtained upper overflow liquid finally flows out from the overflow port of the third-stage concentration device group L3.

From the above description, it should be understood that the next and previous concentrator banks in adjacent two concentrator banks described herein are opposed and may be arranged according to the direction of flow of the fluid (e.g., slurry), e.g., the next concentrator bank is downstream in the flow of the fluid relative to the previous concentrator bank; and the upper stage concentrator group is located upstream of the fluid flow with respect to the lower stage concentrator group. However, this is not a limitation of the present invention, and those skilled in the art can set the setting according to the actual working condition, and can flexibly adjust the change of the fluid flowing direction.

The structure of the plurality of concentration devices in the multistage concentration device group is not limited to the structure shown in fig. 7, and for example, the partition may be provided in other shapes. Further, the plurality of concentration devices of the multi-stage concentration device group may have the same or different structures. Further, the connection manner between the adjacent concentration devices may not be limited to the fitting manner shown in fig. 7, for example, in one embodiment, the box bodies of two adjacent concentration devices may share one surface, so that a plurality of concentration device groups may be connected in an integrated manner. The adjacent concentration devices are connected in a mode of being attached to or sharing the box surface, so that the space can be saved, the layout of the whole thickener is more compact, and the size of the thickener is favorably reduced. In addition, the arrangement of the multi-stage concentration device groups connected in sequence is not limited to the arrangement in sequence at the same height as shown in fig. 7, for example, in one embodiment, the multi-stage concentration device groups are arranged in a high-low step type connection manner, which will be described below with reference to fig. 8.

According to another embodiment of the invention, the overflow of the thickener may be lower than the slurry inlet, and the plurality of thickener sets may be connected in a high-low-level ladder.

While the sequential high-low cascade connection arrangement of the multi-stage concentrator groups is described above with reference to fig. 8, it should be understood by those skilled in the art that the above description with reference to fig. 8 is exemplary and not limiting, for example, the number of stages of the multi-stage concentrator groups is not limited to three stages shown in fig. 8, and more or less stages may be provided as required; the number of the concentration devices in each stage of the concentration device group is not limited to one shown in the figure, and may be more, for example, two, three or more, as needed.

Further, according to an embodiment of the present invention, a plurality of the concentration devices in the concentration device group of each stage may be connected in sequence. For example, as shown in fig. 9, the concentrators 100-11, 100-12, 100-13 of the primary concentrator set L1 may be connected together, and in one embodiment, the concentrator 100-11 and the concentrator 100-12 are attached to each other, and the concentrator 100-12 and the concentrator 100-13 are attached to each other. Similarly, the arrangement of the concentration devices in the second stage concentration device group L2, the third stage concentration device group L3 and the fourth stage concentration device group L4 may be the same as or similar to that in the first stage concentration device group L1, and thus, the description thereof is omitted. With this arrangement, the slurry inlets 111-11 of the thickening apparatuses 100-11, 111-12 of the thickening apparatuses 100-12, and 111-13 of the thickening apparatuses 100-13 can together be the total slurry inlet of the thickener; the overflow ports 112-41 of the concentration devices 100-41, the overflow ports 112-42 of the concentration devices 100-42 and the overflow ports 112-43 of the concentration devices 100-43 can be used together as the total overflow port of the thickener. In practical use, the slurry to be treated can enter the thickener from the slurry inlets 111-11, 111-12 and 111-13 at the same time, and the overflow liquid can flow out from the overflow ports 112-41, 112-42 and 112-43 at the same time. Thus, the treatment capacity of the slurry can be improved, and continuous production can be realized. According to the configuration, the tight connection of the multi-stage concentration device groups can be realized, a compact structure is formed, the space is saved, and the volume of the thickener is favorably reduced and the number of the concentration devices is further increased.

The embodiment of the arrangement of the multi-stage concentration device group according to the present invention is described above with reference to fig. 9, and the arrangement of the multi-stage concentration device group according to the present invention can finally obtain clarified overflow liquid, which is beneficial to further recovery and treatment of the overflow liquid and is of great significance. It should be understood by those skilled in the art that the arrangement of the multi-stage concentrator groups shown in fig. 9 is exemplary and not limiting, for example, the number of stages of the concentrator groups may not be limited to four stages, and more or less may be provided as desired; the number of the concentration devices in each stage of the concentration device group can be not limited to three, and more or less concentration devices can be arranged according to the requirement; the arrangement may be the same as or similar to that of the thickening apparatus shown in fig. 9 and will not be described in detail here. Fig. 9 shows an arrangement of a plurality of concentration devices in adjacent two-stage concentration device groups, and a case where the number of concentration devices in adjacent two-stage concentration device groups is not equal will be described below with reference to fig. 10.

Fig. 10 is a schematic top view of an embodiment showing the unequal number of concentrators in adjacent two-stage concentrator groups according to the present invention. Since the second movable chassis of the movable thickener is the same as or similar to that described in the foregoing, it will not be described herein again and thus is not shown in fig. 10. The multi-stage concentration apparatus set shown in fig. 10 will be described below. According to one embodiment of the invention, the number of concentration devices in the next concentration device group in two adjacent stages is smaller than the number of concentration devices in the previous concentration device group, and each of the concentration devices in the next concentration device group may be connected to at least one of the concentration devices in the previous concentration device group.

The multi-stage concentration apparatus group as shown in fig. 10 may include a one-stage concentration apparatus group L1 (shown by a dotted line box), a two-stage concentration apparatus group L2 (shown by a dotted line box), and a three-stage concentration apparatus group L3 (shown by a dotted line box). The primary concentrating apparatus group L1 may be adjacent to the secondary concentrating apparatus group L2, and the number of concentrating apparatuses in the secondary concentrating apparatus group L2 (the next concentrating apparatus group) is less than that in the primary concentrating apparatus group L1 (the previous concentrating apparatus group), for example, the secondary concentrating apparatus group L2 may include two concentrating apparatuses 100-21, 100-22, and the primary concentrating apparatus group L1 may include three concentrating apparatuses 100-11, 100-12, 100-13. Similarly, the second concentrator group L2 may be adjacent to the third concentrator group L3, and the number of concentrators in the third concentrator group L3 (the next concentrator group) may be less than the number of concentrators in the second concentrator group L2 (the previous concentrator group), for example, one concentrator 100-31 may be included in the third concentrator group L3, and two concentrators 100-21, 100-22 may be included in the second concentrator group L2.

Further, each of the concentration devices in the next-stage concentration device group in the adjacent two-stage concentration device groups may be connected to at least one concentration device in the previous-stage concentration device group. This is illustrated below in connection with fig. 10. As shown in fig. 10, the primary thickener group L1 is adjacent to the secondary thickener group L2, and the thickeners 100 to 21 in the next one of the primary thickener groups (i.e., the secondary thickener group L2) may be connected to the thickeners 100 to 11 in the previous one of the primary thickener groups (i.e., the primary thickener group L1), while the other thickeners 100 to 22 in the secondary thickener group L2 may be connected to the thickeners 100 to 12, 100 to 13 in the primary thickener group L1. Similarly, the secondary concentrator group L2 is in turn adjacent to the tertiary concentrator group L3, wherein the concentrators 100-31 of the next concentrator group (i.e., the tertiary concentrator group L3) may be connected to the concentrators 100-21, 100-22 of the previous concentrator group (i.e., the secondary concentrator group L2).

The above description of the case where the number of the concentration devices in the two adjacent concentration device groups is different is described in connection with fig. 10 by way of example, it can be understood that, during the thickening process of the slurry passing through the multi-stage concentration device group, the amount of the concentrated slurry collected in the concentration device groups of the later stages is gradually reduced, the overflow liquid of the upper layer is gradually clarified, and the multi-stage concentration device group is arranged in a manner similar to the trapezoidal arrangement (for example, as shown in fig. 10), so that the total number of the concentration devices is reduced, the volume of the thickener is reduced, the treatment capacity of the slurry can be ensured, and the volume and the weight of the thickener can be further reduced, which is beneficial to movement.

It should be understood by those skilled in the art that the arrangement shown in fig. 10, which is similar to a trapezoid, is exemplary and not limiting, and that those skilled in the art, given the teachings of this disclosure, may adjust the arrangement according to actual needs. For example, the number of stages of the multistage concentration apparatus group may not be limited to three stages in the drawing, and more or less may be provided as necessary. The number of the concentration devices in each stage of the concentration device group is not limited to one, two or three in the figure, and can be more according to the needs. The number of the concentration devices of the adjacent two-stage concentration device groups may not be limited to one difference, and may be set more than one difference, for example, two, three or more, as required. One concentration device in the next concentration device group in the adjacent two-stage concentration device groups is not limited to be connected with one or two concentration devices in the previous concentration device group, but can be connected more as required. For example, in one embodiment, the concentrator devices 100-21 shown in the figures may be increased in size to connect with 100-11, 100-12, 100-13 of the primary concentrator group L1. It will be appreciated that the sizes of the concentrators in the multi-stage concentrator group may be different, and that another embodiment of arranging concentrators of different sizes in the multi-stage concentrator group will be described with reference to fig. 11.

According to another embodiment of the invention the volume of the concentration devices of a partial group of the plurality of groups of concentration devices is smaller than the volume of the concentration devices of another partial group of groups of concentration devices. FIG. 11 is a schematic diagram showing an embodiment of a different volumetric concentrator arrangement from a top view. Since the second movable chassis of the movable thickener is the same as or similar to that described in the foregoing, it will not be described herein again and thus is not shown in fig. 11. As shown in fig. 11, the multi-stage concentration apparatus group may include a primary concentration apparatus group L1 (shown by a dotted line box), a secondary concentration apparatus group L2 (shown by a dotted line box), and a tertiary concentration apparatus group L3 (shown by a dotted line box). The first-stage concentration device group L1 may include concentration devices 100-11 and 100-12, the second-stage concentration device group L2 may include concentration devices 100-21 and 100-22, and the third-stage concentration device group L3 may include concentration devices 100-31 and 100-32. And the volumes of the concentration units 100-31, 100-32 in the tertiary concentration unit group L3 may be smaller than the volumes of the concentration units in the primary and secondary concentration unit groups L1, L2.

In particular, during the process of thickening the slurry by the multi-stage thickening device group, the amount of the concentrated slurry collected in the later stage thickening device group is generally gradually reduced, and the overflow liquid on the upper layer is gradually clarified, so in one embodiment, a thickening device with smaller volume can be arranged in the later stage thickening device group (for example, similar to the exemplary arrangement mode of the multi-stage thickening device group shown in fig. 11), the requirement of the handling capacity can be met, and meanwhile, the volume of the thickener is reduced, the weight is reduced, and the movement is facilitated.

While one embodiment of arranging different volumes of concentrators in a multi-stage concentrator group is described above in connection with fig. 11, it should be understood by those skilled in the art that the multi-stage concentrator group shown in fig. 11 is exemplary and not limiting, for example, the number of stages of the multi-stage concentrator group may not be limited to three stages as shown, and more or less may be provided as desired. The number of the concentration devices in each stage of the concentration device group is not limited to two as can be shown in fig. 11, and more or less may be provided as necessary. In one embodiment, the number of concentrators in adjacent two-stage concentrator sets may be different. The concentrator group provided with the smaller-volume concentrator is not limited to the three-stage concentrator group shown in fig. 11, and may be adjusted as needed, for example, in one embodiment, the volumes of the concentrators in the five-stage concentrator group and the six-stage concentrator group are smaller than those in the other-stage concentrator group.

Further, in another embodiment, the volume of the concentration device in the next-stage concentration device group in the adjacent two stages may be smaller than the volume of the concentration device in the previous-stage concentration device group. Namely, the concentrating devices among all the stages in the multi-stage concentrating device group are arranged in a way that the volumes of the concentrating devices are reduced in sequence. Such an arrangement may further reduce the volume and weight of the thickener, thereby facilitating flexible movement. And the volumes of the plurality of the concentrating devices in each stage of the concentrating device group can be set to be equal or unequal according to requirements.

While the number, volume, etc. of the multiple concentrators in the multi-stage concentrator group are described above with reference to fig. 7-11, embodiments of the concentrator including a turbidity sensor and a overflow collection tube according to the present invention will be described with reference to fig. 12.

According to yet another embodiment of the present invention, the mobile thickener may further comprise at least one turbidity sensor and at least one overflow liquid collection pipe, wherein the turbidity sensor is arranged on the concentration devices in the partial-stage concentration device group in the multi-stage concentration device group to monitor the turbidity of the overflow liquid in the concentration devices; the overflow liquid collecting pipe is connected to the overflow port of the concentration device provided with the turbidity sensor, and an automatic control device is arranged on the overflow liquid collecting pipe and connected with the turbidity sensor so as to control the opening and closing of the overflow liquid collecting pipe according to the turbidity of the overflow liquid.

As shown in fig. 12, the mobile thickener may include a multi-stage thickener set and a second mobile chassis 200. Wherein the multi-stage concentration device group may include a primary concentration device group L1 (shown by a dotted line box), a secondary concentration device group L2 (shown by a dotted line box), and a tertiary concentration device group L3 (shown by a dotted line box). The primary concentrating device group L1 may include at least one concentrating device 100-1, the secondary concentrating device group L2 may include at least one concentrating device 100-2, the tertiary concentrating device group L3 may include at least one concentrating device 100-3, and the concentrating device 100-1, the concentrating device 100-2, and the concentrating device 100-3 may be connected in sequence, wherein an overflow port of the concentrating device 100-1 may be connected to a slurry inlet of the concentrating device 100-2, and an overflow port of the concentrating device 100-2 may be connected to a slurry inlet of the concentrating device 100-3.

In this embodiment, a turbidity sensor may be disposed on the concentration devices in the two-stage concentration device group L2 to monitor the turbidity of the overflow liquid in the concentration devices in the two-stage concentration device group. Such as the thickening apparatus 100-2 shown in fig. 12, has at least one turbidity sensor 170-2 disposed thereon. Further, a collection tube for overflow liquid may be disposed (including directly or indirectly connected) on the overflow port of the concentration device in which the turbidity sensor is disposed. For example, at least one overflow collection tube 180-2 is connected to the overflow port of the concentration device 100-2 shown in FIG. 12. an automatic control device 190-2 can be disposed on the at least one overflow collection tube 180-2. the automatic control device 190-2 can be connected to the turbidity sensor 170-2 by wire or wirelessly. The automatic control device 190-2 of the concentration device 100-2 can automatically control the opening and closing of the overflow liquid collection pipe 180-2 according to the turbidity of the overflow liquid fed back by the turbidity sensor 170-2 so as to control the outflow path of the overflow liquid in the concentration device 100-2. For example, in one embodiment, when the turbidity sensor 170-2 detects that the overflow liquid has a low turbidity and reaches a limit value at which it can be collected, the automatic control device 190-2 can automatically open the overflow liquid collection pipe 180-2 to allow the overflow liquid in the concentration device 100-2 to be directly drained from the overflow liquid collection pipe 180-2 for further subsequent processes without entering the concentration device 100-3 for further concentration. Therefore, the device can reduce equipment loss, shorten thickening time, save labor cost and realize automatic control.

Further, the overflow port of the thickener 100-2, the overflow liquid collecting pipe 180-2, and the slurry inlet of the thickener 100-3 may be connected by, for example, providing a three-way pipe, so that two outflow paths of the overflow liquid of the thickener 100-2 can be realized. In another embodiment, the portable thickener may further comprise a movable baffle disposed on the overflow port of the concentration device (i.e., the concentration device in which the turbidity sensor is disposed) in the partial-stage concentration device group, and the overflow liquid collection pipe is connected to the movable baffle. For example, a movable baffle is arranged on an overflow port of the concentration device 100-2, the overflow liquid collecting pipe 180-2 is connected to the movable baffle, when the movable baffle closes the overflow port, the overflow liquid flows out from the overflow liquid collecting pipe 180-2, when the movable baffle leaves the overflow port, the overflow liquid flows into a slurry inlet of the concentration device 100-3 through the overflow port, and the automatic control device 190-2 can control the opening and closing of the overflow liquid collecting pipe 180-2 by controlling the movement of the movable baffle, so that two outflow paths of the overflow liquid of the concentration device 100-2 are realized.

While the concentrator device (set) has been described above in connection with fig. 12, with the turbidity sensor, overflow collection tube, and autonomous control, it should be understood by those skilled in the art that the concentrator shown in fig. 12 is exemplary and not limiting, and that those skilled in the art can make adjustments as needed, given the teachings of the present disclosure. For example, the number of stages of the multistage concentration apparatus group is not limited to three stages shown in fig. 12, and more or less may be provided as necessary. The number of the concentration devices in each stage of the concentration device group is not limited to one shown in fig. 12, and may be more, for example, two or three or more, as needed. The concentrator group provided with the turbidity sensor, the overflow liquid collecting pipe and the automatic control device is not limited to the two-stage concentrator group shown in fig. 12, and can be adjusted according to the number of stages of the concentrator group set in practical application, the sediment content of the slurry to be treated and the like. In one embodiment, all the concentrating devices in the multi-stage concentrating device group are provided with a turbidity sensor, an overflow liquid collecting pipe and an automatic control device. In another embodiment, the concentration devices in the last few (e.g., the last three) stages of the multi-stage concentrator group have turbidity sensors, overflow collection tubes, and automatic controls disposed thereon. In yet another embodiment, in a certain level of concentrator group requiring the arrangement of turbidity sensors, overflow collection tubes and automatic control devices, only part of the concentrators are arranged.

Given the teachings of this disclosure, one skilled in the art may make adjustments to the number of stages in an exemplary multi-stage concentrator group, the number of concentrators in each stage concentrator group, the configuration and placement of the concentrators, etc. to accommodate different application scenarios and production needs, while still falling within the scope of the present invention as defined by the claims.

Further, the movable thickener according to the invention can be provided with more thickening devices as required, and the treatment capacity of the slurry is ensured by the arrangement according to the invention. Further, the concentration of the thickened slurry can be controlled by controlling, for example, the opening sequence and timing of the underflow discharge valves of the different thickening apparatuses, depending on the concentration of the treated slurry in the thickening apparatuses at different locations, the amount of sedimentation of the slurry, etc. For example, the slurry concentration of the thickener in the previous thickener set in the adjacent two-stage thickener set is greater than the slurry concentration of the thickener in the next thickener set, in one embodiment, the underflow discharge valve of the thickener in the previous thickener set in the adjacent two-stage thickener set is opened earlier than the underflow discharge valve of the thickener in the next thickener set.
