New description: 【.New technical field of the invention】 This creation is a technical pure field of the kind of sludge weaving equipment, especially the suction device for the sinking pond. [Prior Art] - Water treatment equipment such as the shipwreck of the sewage treatment plant in the water supply plant must be reduced in order to reduce the water use or the water treatment process (for example, reduce the load on the pond). First remove the sludge from Shen Dianchi. For example, in the sink pond of the waterworks, the original water system of the waterworks comes from the reservoir or river or groundwater, and the mud or suspended particles entrained in the raw water are removed by the water treatment process. And whether it is a water tank or a sedimentation tank such as sewage treatment. In addition to the use of soil and water conservation or the use of various sources of sludge control to reduce the source of sludge. For sludge or suspended particles that have been caused to be contained in raw water, most of them are removed by natural static or medicated coagulation. The sludge deposited at the bottom of the tank needs to be further removed by water treatment process or equipment, for example, The pumping mud includes the sludge pumping pipeline, and the sediment sludge at the bottom of the tank is turned outside the pond, so that the sedimentation tank can be continuously operated to reduce the load of the subsequent water treatment plant or the sewage treatment plant processing process (for example: Filter pool). Although the prior art cistern has a suction device, that is, a mud collecting pipe is arranged in the sinking pool, and the collecting pipe extends more than one suction pipe vertically in the sedimentation tank. In the collection of mud pipes and suction pipes, if there is only one suction pipe, the shape cover is in the shape of "ten". If there are two suction pipes, the shape cover is in the shape of "廿". Since the suction pipe has a plurality of 5 M348126 « a 7~ hole, and communicates with the mud collecting pipe, and the outside of the collecting pipe passes through the powerful sludge pumping equipment, the sludge sucked by the suction pipe passes through the mud The tubes are collected and discharged into the sinking pool. Although the prior art has the advantage of solving the sludge, there is still more room for dreams. For example, when there are one or more suction pipes responsible for sucking mud, 'because the pumping force in the mud collecting pipe is mostly from the pool side The sludge pump is pumped, and the suction pipe is recorded because of the distance from the "_力源". The effect of suctioning the mud is often different. For example, the distance π is the distance from the source of the force, and the effect of the sediment is not as good as the distance. The source is closer, so the effect is not fully utilized. [New content] In view of the problems of the prior art, this creation believes that there should be an improved design. Mainly, I will use the internal reciprocating operation of the sub-tube 5, so that the sub-tube can be externally connected to the sinking pool _^· to achieve the average of the whole fiber pool and the sediment sludge. Because the sub-tube = part and set Liu Bu ® this Na fiber: the dirt of the mud collecting pipe tends to be similar or similar, which can make the suction effect more average and efficient. t The technical means adopted to solve the first problem, including the two groups of suction pipes that are separated from each other in the vertical direction of the official. The collecting pipe comprises a front and a second tube, and a front and a cross-shaped money is arranged, and a free end of the scale-cutting soil support is provided with a throttling ring, and the throttle ring is provided with a perforation; Two = the masterbatch part, allowing the sub-recorder mother tube __ relatively extended and "/that is, the outer edge of the flow ring is attached to the parent tube (4), except for the section such as the inner edge of the mother tube and the outer edge of the sub-tube Keep-pitch. I is outside '6 M348126 g ,. Circle selection::... 【Embodiment】 The following is a description of the content, features and examples of this creation, so that a clearer one is provided for review. This creation is about a suction device for sedimentation tanks, as shown in the first figure, in combination with the sedimentation tank (1) in the second diagram, for the purpose of suctioning mud, including a collection of mud pipes (2) The collecting mud pipe (the first suction pipe (3) and the second suction pipe (4) extending in a vertical direction from each other. Each suction pipe '(3), (4) is provided with a plurality of suction holes (31), (41) ) to facilitate the suction of the sludge at the bottom of the sedimentation tank (1). 凊 Refer to the second and fourth figures, and the collection of the mud raft includes a sub-tube (21). Through the tunnel (2η), and The end of the sub-tube (21) extends a throttle ring bracket (212). The free end of the throttle ring bracket (212) is provided with a throttle ring (213), and the throttle ring (213) is provided with a through hole (214). a mother tube (22): the mother tube (22) is sleeved on the outer edge of the sub-tube (21), allowing the sub-tube (21) to run axially relative to the inner tube (22); and the sub-tube The throttle ring (213) of the tube (21) is attached to the inner tube wall of the mother tube (22), except for the throttle ring (213), the inner edge of the mother tube (22) and the sub-tube (21) The outer edge maintains a spacing (218). > and the outer edge of the mother tube (22) is spaced apart from the first suction pipe (the first suction pipe) which is perpendicular to the mother pipe (22) and communicates with the mother pipe (22) 3) and the second suction pipe (4). The bottom of the first suction pipe (3) is provided with a plurality of mud collecting plates (33), and the bottom of the second suction pipe (4) may also be provided A plurality of mud plates (43), which can be combined or selected to provide a smooth and loose front function for the bottom of the aerodium (1) before the sludge is sucked, which is beneficial to the subsequent The suction operation is carried out. Please refer to the second and third figures. As shown in the partial enlarged view of the fourth figure, this creation can be mainly The mother tube (22) is relatively retractable at the outer edge of the sub-tube (9), that is, the counter-tube (9) M348126 i reciprocates at the inner edge of the parent (22), and the sub-tube (21) is externally connected to the sedimentation tank (1). In addition, the sludge pump is connected (not shown), and a stainless steel cable (5) can be fixed on the outer edge of the mother pipe (22). The non-steel wire (5) can be wound around the sedimentation tank (1). The inner wheel seat (10) can be pulled forward by the driving unit provided on the bank of the pool to make the mother tube (22) move forward and backward. Please refer to the first and fourth figures, together with the figure shown in the fifth figure, and for the smooth and smooth reciprocating advance and retreat' The mother tube (22) is provided with a set of ground wheels (220) which can be attached to the bottom wall of the sedimentation tank (1). The first suction pipe (3) and the second suction pipe (4) may be selected one or both, and a set of wall wheels (32) attached to the inner side wall of the sinking pool (1) are provided at both ends, ( 42). It is also possible to make the reciprocating advance and retreat smoother and smoother, and the main tube (22) maintains a distance (218) from the outer edge of the sub-tube (21) due to the throttle ring (213). Therefore, the throttle ring (213) between the holes (211) of the sub-tube (21) and the spacing (218) form a pinch of the first suction pipe (3). As for the throttle ring (213) 'which can be used as the first suction pipe and the second suction pipe (4) to absorb the sludge quantity control adjustment element, since the throttle ring (213) is provided with a perforation (214), It is therefore possible to provide a path for the sub-tube (21) tunnel (211) to be broken into by the second suction pipe (4). In another embodiment of the invention, the front edge of the throttle ring (213) is opposite to the direction of the sub-tube (21), and a second bracket (215) can be further extended. The second bracket (215) is free. There is a front baffle (216)' and a spacing (217) between the front baffle (216) and the inner side wall of the female pipe (22). The front baffle (216) can be used to buffer the sludge from the second suction pipe (4), but because of the spacing (217) between the front baffle (216) and the inner side wall of the main pipe (22), Therefore, it can still be used as a circulation path, not completely blocked. Since the first suction pipe (3) and the second suction pipe (4) are simultaneously controlled by the suction sludge of the throttle ring (213), and the force of B is drawn inside the mother pipe (22). , with the sub-tube (21) 8 M348126 external sedimentation tank (1) sludge pump (not shown), due to the scale of the first suction pipe (3) or the first - and mud 1 (4) and § 'incorporate The sludge flow rate of the mud pipe (2) tends to be the same or similar, and the operation of stabilization and balance can be achieved. This creative office wants to become a confusing target. According to the general water supply of the water treatment plant and the sewage treatment plant, it is not too clear, which leads to the lack of mutually coagulated sludge particles, which makes the operation of the temple difficult. If the proportion of sludge according to job is lighter than water, it is difficult to reach a job. Therefore, in general, the coagulant is added in the treatment of water, in order to reduce the potential of the surface of the sludge particles, and at the same time act as a bridge for condensation. The sludge microparticles in the water mostly have the same electric charge on the surface, and the electrostatic repulsion between the sludge microparticles. • The potential of the static electricity must be lowered. When the potential is lowered, the repulsive force between the particles disappears and the particles adhere to each other. Therefore, it is necessary to add an ion having the opposite sign, that is, the aforementioned coagulant, such as alum, to completely agglomerate. The bridging action between the particles is coarsened, and when the coarsening, the sludge microparticles in the water can be gathered to form a specific gravity larger than the water to form a sink. In summary, the creation has practical effects, and has not been found in publications or public use to meet patent requirements, and patent applications are filed according to law. The above-mentioned evidence is the preferred embodiment of the creative industry. The equivalent changes made by the patent scope of this patent are the scope of patent application in this case.
