Detailed Description

It should be noted that the physical properties of different wastes are different, and the degree of crushing is different for the same crushing member and the same crushing strength and crushing time. For example, fibers are difficult to be rigidly broken, while glass, for example, is fragile and is easily rigidly broken.

In the structure shown in fig. 1, the helical reamer 7 used as the main crushing member is arranged transversely in the drawing, different materials produce different crushing effects in the progressive advancing process, and natural screening occurs, which has a screening effect satisfying industrial applications although precise screening cannot be achieved.

In addition, as described in the background art, even if manual screening with the best screening effect is performed, the wastes are physically exchanged after being mixed, and the screening significance is not great, in other words, the fine screening is only in an ideal state and has no practical significance, so that the method of adopting the coarse screening for screening the wastes has more practical industrial value.

The household garbage crushing apparatus shown in fig. 1 is a horizontal garbage crushing apparatus as a whole, and the main shaft 4 is of a horizontal structure and is in a substantially horizontal state when installed. The household garbage crushing device shown in fig. 1 mainly comprises a bracket 17, a screw crusher, a feeding device, and a driving device for driving the screw crusher and the movable part in the feeding device. The spiral crusher mainly comprises a cylindrical housing forming a tube cavity and a spiral reamer 7 which is arranged in the housing and coaxial with the housing; the feeding device comprises a feeding bin 5 and a fiber crushing wheel 6 arranged in the feeding bin 5.

The support 17 shown in fig. 1 includes support legs and a support platform installed on the support legs, the support platform is a frame structure, and the support legs are used for supporting the support platform to a certain height, which is beneficial to the arrangement of a plurality of discharge ports as shown in the figure and the arrangement of a feeding mechanism adapted to the discharge ports.

The mantle of the screw crusher is in fig. 1 fixedly arranged, which is fixedly arranged on the support platform. The posture of the housing is horizontal, namely a roughly horizontal state, and the corresponding main shaft 4 and the housing are coaxial, wherein the coaxial is an ideal state or a design parameter, and the actual assembly has assembly errors which are within the tolerance of the coaxial and belong to the coaxiality problem rather than the distance parameter of the corresponding two axes of a specific design.

In fig. 1, the housing body is composed of three segments, and more segments can be provided according to the composition difference of garbage.

The housing can be understood as a cylindrical screen with screen holes distributed on the wall surface in the figure 1 as a whole, and in the process of crushing and pushing the materials backwards, the materials meeting the sieving condition can be sieved through the screen holes of the screen, and obviously, the materials not meeting the sieving condition can be further crushed and further pushed.

Consider that there is partial rubbish to belong to the rubbish that is difficult to smash, be different from the conventional smash step by step, the more principle that the granularity is more thin backward the embodiment of the utility model, the screen cloth of adaptation, screen cloth mesh is bigger backward more, easily by broken promptly, broken promptly at the preceding stage, be difficult to the breakage, also can not have fine crushing effect at the back, this kind utilizes different rubbish to sieve in the face of the different phenomenon of same broken part crushing capacity, has the effect of rough branch, can accomplish the preliminary separation of rubbish, provides better basis for subsequent processing.

In the arrangement shown in figure 1, the screen at the last stage, the third screen 14, is on a scale having relatively large mesh sizes to enable a substantial proportion of the waste to be screened, the housing is shown with a rear end cap, which in some embodiments is absent to enable the non-pulverisable material to be discharged directly from the rear end of the housing, and accordingly a collection hopper may be provided at the rearmost side of the housing.

Correspondingly, because the housing wall is not the confined wall, but comprises the screen cloth, for this reason, in the utility model discloses an embodiment, dispose a plurality of discharge gates, the quantity of discharge gate with the festival section is the same to the one-to-one disposes in corresponding festival section downside, in order to accept corresponding festival section sieve material.

It is common knowledge in the art to provide a multi-stage comminution apparatus having a front stage and a rear stage in a defined flow relationship. In the embodiment of the present invention, the main shaft having the determined axis has two determined ends, such as the left end and the right end shown in fig. 1, the left end in the figure constitutes the front end based on the circulation relationship of the materials, and correspondingly, the right end in the figure is the rear end.

In fig. 1, the front end of the housing is fitted with a feed bin 5, the feed bin 5 being seen in fig. 1 as a rectangular bin, while in other embodiments the feed bin 5 as a whole may be configured as a hopper-like feed bin 5, it being understood that the hopper-like feed bin 5 has a gradually converging structure.

In some embodiments, the mouth of the feed bin 5 in the rectangular bin state may also have a tapered hopper.

Since the crushing member in the screw crusher is liable to wind fibers such as clothes and the like made of fibers, for this purpose, a fiber crushing mechanism such as a fiber crushing wheel 6 shown in fig. 1 is provided in the feed bin 5.

Regarding the fiber crushing mechanism, currently, one or two cutter wheels are mainly used, or configured as a cutter wheel set, each cutter wheel set has two cutter wheels, and when two or two cutter wheels are configured on a cutter wheel set, or when two cutter wheels exist in a group of cutter wheels, the two cutter wheels are opposite in rotation direction. Regarding the fiber crushing mechanism, it belongs to one of crushing mechanisms equipped with conventional garbage crushers, and is not described herein again. The embodiment of the utility model provides an in, mainly configure its preceding stage mechanism into the screw crusher, avoid fibre class rubbish winding on the screw reamer 7 that the screw crusher is configured.

Considering that the crushing capacity and the conveying speed of the helical reamer 7 are positively correlated with the rotating speed thereof, and the crushing effect is also positively correlated with the crushing time, when it is intended to obtain a good crushing effect by increasing the rotating speed of the helical reamer 7, the crushing time is shortened due to the increase of the rotating speed of the helical reamer 7. For this reason, in the embodiment of the present invention, the protruding rings, such as the first protruding ring 11 and the second protruding ring 13 shown in fig. 1, are provided between the segments in the housing to obstruct the material to a certain extent, so that the material can be well crushed at a predetermined speed.

Correspondingly, the bulge loop is the ring, and the outer lane of ring combines with the housing inner wall to form the threshold effect in the housing, make the material have certain dwell time at the preceding stage, simultaneously, also reduced the coarse fodder and wrapped up in the volume of holding the fine material.

Correspondingly, in order to avoid generating movement interference, the spiral reamer 7 is damaged at the convex ring to form a multi-section spiral.

Further, the height of the convex ring at the front stage is larger than that of the convex ring at the rear stage, and it is expected that finer material can be screened out at the front stage by screening based on the above, and the longer the material retention time is, the higher the probability that fine material carried by coarse material is screened out is, which requires that the material is retained for a longer time at the front stage; in the later stage, as the material becomes relatively thicker, the mutual gripping capacity also decreases, the requirement for retention capacity at the corresponding segment becomes lower, and the requirement for retention effect of the corresponding convex ring also becomes lower.

It should be noted that, under the influence of the convex ring, the whole helical reamer 7 is composed of the multiple helical reamers, and according to the design requirements, the helical reamers of different lead lengths can be adopted in each section, so that the conveying capacity of the helical reamers of different sections is different under the condition of the same rotating speed.

Preferably, the collar is up to 45mm and down to 20 mm.

In order to reduce the influence of corrosive substances such as landfill leachate and the like which possibly seep out on a bearing, a shaft seat 2 for supporting a main shaft 4 of the spiral reamer 7 is positioned outside the housing; correspondingly, the two ends of the housing are provided with sealing covers, through holes for the main shaft 2 to pass through are formed in the sealing covers, and rotary sealing elements are arranged between the through holes and the main shaft 4. According to the structure, the shaft seat 2 for supporting the main shaft 4 is positioned outside the housing, is not easy to be directly contacted by corrosive components in garbage, is not easy to generate failure risk, and has relatively long service life.

In addition, a box body is arranged outside the housing to contain the housing, although most of screened materials can be led out from the lower side of the housing, a small amount of materials can be led out from other sides of the housing, and the box body is used for avoiding uncontrolled scattering of the materials so as to lead the materials to corresponding discharge ports, and simultaneously can also avoid uncontrolled dissipation of waste gas generated by the relatively semi-open housing.

In contrast to the previously described platforms configured as racks, in particular support platforms, the box is mounted on the support platform with a given support height for adaptation of the height of the outfeed, for example, in fig. 1.

Corresponding in addition, the discharge gate is formed by going out the hopper, goes out the corresponding supporting platform downside that is located of hopper, goes out the height that self height of hopper also is used for adjusting the discharge gate for the installation of the ejection of compact conveying mechanism that the adaptation is sent.

In order to save space, a motor for providing power is positioned in the space below the supporting platform and is connected with the fiber crushing mechanism and the spiral reamer 7 through a transmission mechanism.

Because the components of the garbage are complex and are not uniformly distributed, the load of the spiral reamer 7 in the crushing process is irregularly changed, instantaneous larger resisting moment is easily generated, and in order to avoid the damage of a rigid transmission mechanism, the transmission mechanism for connecting the spiral reamer 7 and a motor comprises a transmission mechanism with a flexible transmission part, such as a chain transmission mechanism or a belt transmission mechanism.
