Description

Technical Field

[0001] The invention relates to the technical field of pulverizers, and in particular to a waste pulverizer. Background Art

[0002] Solid waste refers to solid or semi-solid items generated in the process of production, life and other activities that have lost their original utilization value or have not lost their utilization value but have been discarded or abandoned. These wastes are divided into recyclable waste and non-recyclable waste. Recyclable waste includes five categories: electrical and electronic products, waste paper, waste plastic, waste glass, waste metal, etc. Before recycling the waste, it is necessary to use a shredder to crush the waste to facilitate subsequent processing.

[0003] A solid waste pulverizer is disclosed in a Chinese patent application document with publication number CN117019325A. The solid waste pulverizer, through the coordinated use of a first slider, a rotating shaft, a first blade, a columnar pin, a connecting rod, a T-block, a circular plate and a return spring, is convenient for directly rotating and replacing the blade of a blade in the pulverizer when one of the blades is worn or damaged, without the need to disassemble the blade, thereby reducing the maintenance time of the equipment for the staff and improving the pulverization efficiency of plastic waste.

[0004] However, the structural design of the above-mentioned related technology: although the blades can be replaced quickly, when crushing some wastes with grease, the crushed wastes will be affected by the grease and stick to the filter net, and the high temperature generated during the crushing process will also increase the fluidity of the grease, causing the grease to flow to other positions on the filter net, thereby causing the mesh holes on the filter net to be blocked or the waste to be crushed multiple times, affecting the discharge efficiency, and requiring the machine to be stopped for cleaning, which will affect the waste crushing efficiency.

[0005] Therefore, a waste crusher is proposed to solve the above problems. Summary of the invention

[0029] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0030] like Figures 1 to 7 As shown, the waste crusher of the present invention comprises a base 10, a crushing mechanism 20, a cleaning mechanism 30, a filtering mechanism 40 and an adjusting mechanism 50. The crushing mechanism 20 is installed on the top of the base 10 for crushing materials. There are two filtering mechanisms 40, which are rotatably arranged inside the base 10 for filtering the crushed materials. The two filtering mechanisms 40 are arranged up and down with a spacing. There are two cleaning mechanisms 30, which are respectively arranged on both sides of the filtering mechanism 40 to clean the filtering mechanism 40. The adjusting mechanism 50 is arranged at the rear side of the base 10 for driving the two filtering mechanisms 40 to rotate.

[0031] When the crushing mechanism 20 is crushing the material, one of the filter mechanisms 40 screens the crushed material. When the filter mechanism 40 in use is blocked, the adjustment mechanism 50 drives the other filter mechanism 40 to rotate to a horizontal state and continue to screen the material, and then rotates the blocked filter mechanism 40 to a vertical state and approaches the cleaning mechanism 30. At this time, the cleaning mechanism 30 cleans the blocked filter mechanism 40 to facilitate the subsequent screening of the material.

[0032] like Figures 1 to 3 As shown, the base 10 includes a shell 11 installed at the bottom of the crushing mechanism 20.

A connecting rod 424 is installed at one end of the reel 422 through a one-way bearing, and one end of the connecting rod 424 passes through the mounting seat 423 and the housing 11 in sequence and extends to the outside of the housing 11, and a gear 425 is installed at one end of the connecting rod 424 passing through the support frame 41. The connecting rod 424 located in the lower filtering mechanism 40 is arranged in the guide groove 1 14 , and the connecting rod 424 located in the upper filtering mechanism 40 is arranged in the guide groove 2 26 .

[0037] like Figures 1 to 3 and Figures 5 and 6As shown, the adjustment mechanism 50 includes a protective cover 51, an adjustment assembly 52, two racks 3 54 and two racks 4 55. The protective cover 51 is installed on the rear side of the crushing chamber 21, and the shapes of the racks 3 54 and 4 55 are both arc-shaped. The rack 3 54 is installed on the rear side of the crushing chamber 21 and is located on the inner side of the guide groove 26. The two ends of the rack 3 54 are respectively arranged away from the two ends of the guide groove 26, and the rack 3 54 can mesh with the gear 1 425 located in the upper filtering mechanism 40. The rack 4 55 is installed on the rear side of the housing 11 and is located on the outer side of the guide groove 14. The end of the rack 4 55 is arranged close to the end of the guide groove 14, and the rack 4 55 can mesh with the gear 1 425 located in the lower filtering mechanism 40.

[0038] like Figure 3 , Figures 5 and 6 As shown, the adjustment assembly 52 includes a movable plate 521, a rack 1 522 and a rack 2 523. A first connecting portion extending vertically downward is provided on one side of the movable plate 521, and a second connecting portion extending vertically upward is provided on the other side of the movable plate 521.

There are two racks 1 522 and two racks 2 523, one of which is mounted on the first connecting portion of the movable plate 521, and the other of which is mounted on the second connecting portion of the movable plate 521. The rack 1 522 is located above the rack 2 523, and the teeth of the two racks 1 522 face opposite directions, and the rack 1 522 faces the same direction as the gear 2 44. The rack 1 522 can mesh with the gear 2 44 in the upper filtering mechanism 40 , and the rack 2 523 can mesh with the gear 2 44 in the lower filtering mechanism 40 .

[0039] like Figure 3 and Figure 5 As shown, a vertical plate 525 is installed on one side of the bottom of the movable plate 521, and a telescopic member 53 is installed on one side of the vertical plate 525. In this embodiment, the telescopic member 53 is a cylinder. In other embodiments, the telescopic member 53 is a hydraulic cylinder or an electric telescopic rod. One end of the telescopic member 53 is installed on the inner wall of the protective cover 51.

[0040] The telescopic member 53 can drive the movable plate 521 to slide horizontally in the fixed frame 524 through the vertical plate 525, and the movable plate 521 can drive the rack 1 522 and the gear 2 44 to move synchronously during the sliding process. When the telescopic member 53 drives the vertical plate 525 to move in a direction away from the telescopic member 53, the gear 2 523 can drive the gear 2 44 in the lower filter mechanism 40 to rotate, thereby driving the lower filter mechanism 40 to rotate downward. When the telescopic member 53 drives the vertical plate 525 to move in a direction close to the telescopic member 53, the gear 1 522 can drive the gear 2 44 in the upper filter mechanism 40 to rotate, thereby driving the upper filter mechanism 40 to rotate upward, so that the filter mechanism 40 is close to the cleaning mechanism 30.

[0041] like Figure 1 to Figure 2 As shown, the cleaning mechanism 30 includes a mounting frame 31, a driving assembly 32 and a cleaning assembly 33. The mounting frame 31 is mounted on one side of the crushing chamber 21 and is connected to the crushing chamber 21, and the bottom of the mounting frame 31 extends vertically downward to the inside of the housing 11. The bottom of the mounting frame 31 and the side of the mounting frame 31 facing the crushing chamber 21 are both provided with openings to discharge unqualified materials on the filter screen 45 and materials that need to be cleaned. The driving assembly 32 is arranged on the top of the mounting frame 31, and the cleaning assembly 33 is arranged on the driving assembly 32 and is located inside the mounting frame 31.

[0042] like Figure 2 and Figure 7 As shown, the driving assembly 32 includes a motor 321, a lead screw 322 and a connecting block 324. The motor 321 is mounted on one side of the top of the mounting frame 31, and the lead screw 322 is mounted on one end of the driving shaft of the motor 321. The connecting block 324 is threadedly connected to the outside of the lead screw 322, and one end of the lead screw 322 is rotatably connected to a support plate 323, which is mounted on the other side of the top of the mounting frame 31, and the cleaning assembly 33 is arranged on the connecting block 324.

[0043] The motor 321 can drive the cleaning assembly 33 to move back and forth along the length direction of the screw 322 through the connecting block 324 on the screw 322 to clean the oil stains on the filter screen 45.

[0044] like Figure 2 , Figure 5 and Figure 7As shown, the cleaning assembly 33 includes an air pipe 331, an air nozzle 332, a liquid supply pipe 334 and an atomizing nozzle 335. There are two groups of air nozzles 332, which are arranged up and down and have a spacing between the two groups of air nozzles 332. There are multiple air nozzles 332 in each group, and multiple air nozzles 332 are evenly distributed on the outside of the air pipe 331 along the length direction of the air pipe 331. The top of the air pipe 331 passes through the top of the mounting frame 31 and is mounted on the connecting block 324. The top of the mounting frame 31 is provided with a groove for the air supply pipe 331 to slide. A fixing plate 333 is installed at the bottom of the air pipe 331, and the liquid supply pipe 334 is installed on one side of the top of the fixing plate 333. There are two groups of atomizing nozzles 335, which are arranged up and down and have a spacing between them. There are multiple atomizing nozzles 335 in each group, and multiple atomizing nozzles 335 are evenly distributed on the outside of the liquid delivery pipe 334 along the length direction of the liquid delivery pipe 334. Solenoid valves are installed on the air nozzle 332 and the atomizing nozzle 335. The bottom end of the air pipe 331 is connected to an external air pump to deliver compressed gas to the air pipe 331. The bottom end of the liquid delivery pipe 334 is connected to an external liquid delivery pump to deliver oil cleaning agent to the liquid delivery pipe 334. The liquid delivery pipe 334 sprays atomized oil diluent onto the filter screen 45 through the atomizing nozzle 335 to dissolve the oil on the filter screen 45, and then sprays gas onto the filter screen 45 through the air nozzle 332 on the air pipe 331 to clean the oil on the filter screen 45 and blow out the materials blocked in the filter screen 45.

[0045] Working principle: When crushing, first rotate the filter mechanism 40 located at the bottom downward to a vertical position, so that the filter mechanism 40 located at the top is in a working state, and then send the material into the crushing chamber 21 through an external conveyor belt and crush the material through the crushing assembly 22. At this time, the filter mechanism 40 located at the top screens the crushed material.

[0046] When the filter mechanism 40 located at the top is clogged, the filter mechanism 40 located at the bottom is reset first, and then the filter mechanism 40 located at the top is rotated upward to be vertical. During the rotation of the filter mechanism 40 located at the top, the gear 1 425 in the filter mechanism 40 at the top is meshed with the rack 3 54. At this time, under the action of the rack 3 54, the gear 1 425 drives the reel 422 to rotate through the connecting rod 424, so that the spring in the mounting seat 423 accumulates power. At the same time, the reel 422 drives one of the connecting ropes 426 to reel up, and the other connecting rope 426 to unreel, so as to transfer the filter 45 to the bottom of the support frame 41, so as to discharge the residual materials on the filter 45 from the filter 45.

[0047] When gear 1 425 is disengaged from rack 3 54, the spring in mounting seat 423 is released to drive filter screen 45 to reset, so that filter screen 45 is close to air nozzle 332 and atomizing nozzle 335, and then motor 321 drives air pipe 331 and liquid delivery pipe 334 to move through connecting block 324 on lead screw 322, and at the same time, one group of atomizing nozzles 335 on liquid delivery pipe 334 is opened and sprays atomized oil diluent onto filter screen 45, and after spraying the oil diluent, one group of air nozzles 332 on air pipe 331 is opened and blows air onto filter screen 45 to clean filter screen 45.

[0048] When the filter mechanism 40 located below is clogged, the filter mechanism 40 above is reset first, and then the filter mechanism 40 below is rotated downward. During the rotation of the filter mechanism 40 below, the gear 1 425 in the filter mechanism 40 below is meshed with the rack 4 55. At this time, under the action of the rack 3 54, the filter 45 is transferred to the bottom of the support frame 41 to make the filter 45 closer to the air nozzle 332 and the atomizing nozzle 335. When the filter mechanism 40 below is rotated to vertical, the filter mechanism 40 below is cleaned. When the filter mechanism 40 below is rotated upward, the gear 1 425 gradually disengages from the rack 4 55. When the gear 1 425 is completely disengaged from the rack 4 55, the filter 45 is reset under the action of the spring in the mounting seat 423.

[0049] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
