Description

Technical Field

[0001] This application relates to the technical field of plastic sand removers, and particularly to a plastic sand remover. Background Art

[0002] When recycling plastic waste, plastics are often mixed with some sand and gravel. Therefore, it is necessary to remove the sand through a sand remover. First, the plastics are crushed, and then screened through a sieve.

[0003] However, when the sizes of plastic particles or sand and gravel particles are comparable to the holes of the sieve, the holes of the sieve are likely to be blocked, thus affecting the subsequent screening effect. However, when cleaning the sieve, due to the small aperture of the sieve, it is inconvenient to clean. Utility Model Content

[0004] In order to facilitate the cleaning of the blockage of the sieve, this application provides a plastic sand remover.

[0005] A plastic sand remover provided by this application adopts the following technical solutions:

[0006] A plastic sand remover includes a machine body. A crushing chamber is provided inside the machine body. A crushing blade is arranged inside the crushing chamber. Two sets of sieve components are sequentially arranged along the vertical direction below the crushing blade. The sieve component includes a first mounting frame and a second mounting frame. A plurality of warp threads are arranged inside one of the second mounting frames, and a plurality of weft threads are arranged inside the other second mounting frame. The two second mounting frames are spliced up and down and mounted on the first mounting frame.

[0007] By adopting the above technical solutions, after being used for a period of time, the sieve component becomes blocked. At this time, the sieve component can be disassembled. Then, the two second mounting frames are disassembled from the first mounting frame. Next, the two second mounting frames are disassembled to separate the weft threads and the warp threads, so as to facilitate the cleaning of the blockage on them. After cleaning, the sieve component is reinstalled on the machine body to improve the convenience of cleaning.

[0008] Optionally, a fixing component is arranged on one side of the second mounting frame. The fixing component is located on the side of the second mounting frame close to the other mounting frame. The fixing component is used to fix the two second mounting frames.

[0009] By adopting the above technical solutions, when installing the two second mounting frames, the two second mounting frames can be fixed through the fixing component, so that the weft threads and the warp threads form a sieve.

[0010] Optionally, the fixing component includes a plurality of elastic pieces and limiting blocks corresponding to the elastic pieces. The plurality of elastic pieces are arranged in a circumferential array. The cross section of the elastic piece is arc-shaped. The limiting block is fixed to the outer side of the elastic piece. Another second mounting frame is provided with a first clamping groove for the plurality of elastic pieces to be clamped. A second clamping groove for the limiting block to be clamped is coaxially provided on the side wall of the first clamping groove.

[0011] By adopting the above technical solution, when installing the two second mounting frames, the two second mounting frames are made to approach each other. The limiting block abuts against the notch of the first clamping groove of the other second mounting block, forcing the plurality of elastic pieces to contract inward. Then, the two second mounting frames are pressed, so that the limiting block can be clamped in the second clamping groove.

[0012] Optionally, a first wedge surface is provided at one end of the limiting block away from the second mounting frame. When the first wedge surface abuts against the notch of the first clamping groove, the first wedge surface forces the plurality of elastic pieces to deform in the direction of approaching each other.

[0013] By adopting the above technical solution, when the first wedge surface abuts against the notch of the first clamping groove, only by pressing the two second mounting frames, the first wedge surface can force the plurality of elastic pieces to deform in the direction of approaching each other, so that the limiting block can be clamped in the second clamping groove, and then the two second mounting frames are limited.

[0014] Optionally, the machine body is provided with a maintenance opening communicating with the crushing chamber, and the machine body is provided with a cover plate for covering the maintenance opening.

[0015] By adopting the above technical solution, the maintenance opening and the cover plate are provided to facilitate taking out the screen assembly to clean the blockage.

[0016] Optionally, a connecting block is provided between the plurality of elastic pieces. The connecting block is provided with a plurality of first connecting ropes. The plurality of first connecting ropes respectively correspond to the plurality of elastic pieces. One end of the first connecting rope is fixed to the connecting block, and the other end of the first connecting rope is connected to the end of the elastic piece close to the limiting block. A first sunk groove is provided on the side of the second mounting frame away from the other second mounting frame. The connecting block is fixedly connected with a second connecting rope. The second connecting rope penetrates into the first sunk groove, and a pull ring is fixed to the end of the second connecting rope away from the connecting block.

[0017] By adopting the above technical solution, when it is necessary to clean the blockage, the two second mounting frames are removed from the first mounting frame, and then the pull ring is pulled. The connecting block is driven to move through the second connecting rope, so that the plurality of elastic pieces deform in the direction of approaching each other, and the limiting block is separated from the second clamping groove to disassemble the two second mounting frames.

[0018] Optionally, the first mounting frame is provided with a second sunk groove for clamping two second mounting frames. The depth of the second sunk groove is equal to twice the thickness of the second mounting frame, and the first mounting frame is provided with a limiting component for limiting the second mounting frame.

[0019] By adopting the above technical solution, when installing two second mounting frames, the two second mounting frames are clamped in the second sunk groove, and then the second mounting frames are limited by the limiting component, so that the second mounting frames are installed on the first mounting frame.

[0020] Optionally, the limiting component includes a blocking plate, a rotating shaft and a torsion spring. The blocking plate is rotatably connected to the first mounting frame through the rotating shaft, and the torsion spring forces the blocking plate to rotate to the notch of the second groove.

[0021] By adopting the above technical solution, when the second mounting frame is installed in the second sunk groove, the torsion spring forces the blocking plate to rotate to the notch of the second sunk groove, thereby limiting the second mounting frame.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. After being used for a period of time, the screen assembly is blocked. At this time, the screen assembly can be disassembled, then the two second mounting frames are disassembled from the first mounting frame, and then the two second mounting frames are disassembled to separate the weft and warp, so as to facilitate cleaning the blockage on it. After cleaning, the screen assembly is installed on the machine body again;

[0024] 2. When it is necessary to clean the blockage, the two second mounting frames are removed from the first mounting frame, and then the pull ring is pulled, and the connecting block is driven to move through the second connecting rope, so that a plurality of elastic pieces are deformed in the direction of approaching each other, and the limiting block is separated from the second clamping groove to disassemble the two second mounting frames.
