[0002] The purpose of industrial solid waste is to separate the materials that can be recycled or are not conducive to subsequent processing and disposal process requirements. Waste sorting is based on the differences in particle size, density, magnetism, electricity, photoelectricity, friction, elasticity and surface wettability. It can be divided into screening, gravity separation, magnetic separation, electric separation, photoelectric separation, friction and elastic separation, and flotation. Among them, screening is to use a sieve to pass the fine particles smaller than the sieve hole through the sieve surface, and the coarse particles larger than the sieve hole are left on the sieve surface, so that the materials are divided into different grades. The types of grading screen include circular vibration grading screen, linear grading vibration screen, banana screen and rotary screen. The main advantages of linear grading vibration screen compared with other grading screens include large processing capacity, high efficiency, reliability, flexibility, safety, environmental protection, low noise and low energy consumption.

[0019] EMBODIMENT
[0020] Please refer to Figs. 1-3 The utility model provides the following technical scheme: an industrial solid waste sorting device, including sieve box 1, sieve box 1 inside is provided with sieve plate subassembly. The sieve plate subassembly is composed of a plurality of top plates 2 and a plurality of bottom plates 3, and the top plates 2 and the bottom plates 3 are in one-to-one correspondence and are arranged in parallel. The lower surface of the top plate 2 is tightly attached to the upper surface of the bottom plate 3, and the edge of the top plate 2 is firmly fixed to the inner wall of the sieve box 1. The bottom plate 3 is slidably connected between the two sides and the inner wall of the sieve box 1, ensuring that the bottom plate 3 is stably adjusted forward and backward to adjust the size of the sieve hole 4. The surface of the top plate 2 and the bottom plate 3 is uniformly provided with the sieve hole 4 to realize accurate sorting. In addition, each bottom plate 3 is fixedly connected with a connecting plate 5 on both sides, and the connecting plate 5 is located outside the sieve box 1, facilitating the operation of the connecting plate 5. The sieve box 1 is provided with a let go of the slot 6 at the fixed connection point of the connecting plate 5 and the bottom plate 3, so that the bottom plates 3 are connected with each other through the connecting plate 5. One end of the top of the sieve box 1 is welded with a feed hopper 7, and the other end is provided with a discharge port 8, ensuring the continuous flow of materials. The top plate 2 and the bottom plate 3 are arranged at an inclined angle, the feed hopper 7 is located at one end of the highest point of the top plate 2, and the discharge port 8 is located at one end of the lowest point of the top plate 2, facilitating smooth sorting of materials. The sieve box 1 is provided with an exciter 9 at the bottom to provide necessary power support for the sorting process.
[0021] In order to support the whole and ensure the stable vibration state of the sieve box 1, in the embodiment, as a preferred technical scheme of the utility model, the side walls of the sieve box 1 are symmetrically fixed with support legs 10, and supporting springs 11 are fixed between the support legs 10 and the sieve box 1.
[0022] In order to conveniently and quickly fix the connecting plate 5, in the embodiment, as a preferred technical scheme of the utility model, connecting pieces 12 are welded on the two sides of the outer wall of the sieve box 1 close to the two sides of the connecting plate 5, and the connecting plate 5 and the connecting piece 12 are detachably connected through a pin shaft.
[0023] In order to prevent the dust from leaking at the position slot 6, in the embodiment, as a preferred technical scheme of the utility model, the sieve box 1 is fixed with the dustproof rubber plate 13 on both sides of the position slot 6.
[0024] In summary, the implementation of the technical scheme of the utility model will realize the efficient sorting of materials through the following steps: first, the operator needs to pull the connecting plate 5 to the right end of the position slot 6, and then use the pin shaft to firmly fix the connecting plate 5 and the connecting piece 12 on the box wall of the sieve box 1. During the movement of the connecting plate 5, the bottom plate 3 will move, causing the bottom plate 3 to be staggered with the sieve hole 4 on the surface of the top plate 2, thereby reducing the size of the sieve hole 4. The material is then poured into the feeding hopper 7 of the sieve box 1 and falls onto the top end of the top plate 2. Under the action of the exciter 9, the sieve box 1 produces excitation to drive the top plate 2 and the bottom plate 3 to vibrate, and the material particles roll along the top plate 2. During the rolling process, the material particles with smaller diameters will pass through the sieve hole 4 on the surface of the top plate 2 and the bottom plate 3, fall to the next layer of top plate 2 for further screening, until the material particles of different diameters are discharged through the respective discharge ports 8, and the classification of the material is completed.
[0025] In the case of sieve plate blockage and material jamming, the exciter 9 is turned off, the pin shaft between the connecting plate 5 and the connecting piece 12 is removed, the connecting plate 5 is moved to the left end of the position slot 6, and the pin shaft is inserted to fix the connecting plate 5. At this time, the connecting plate 5 drives the bottom plate 3 to move reversely, causing the sieve hole 4 on the surface of the top plate 2 and the bottom plate 3 to coincide, thereby increasing the size of the sieve hole 4. After the exciter 9 is turned on again, the material particles stuck in the sieve hole 4 will smoothly pass through the sieve hole 4, fall to the surface of the next layer of top plate 2, and be discharged from the discharge port 8. Then, the operator needs to adjust the position of the connecting plate 5 to restore the normal working state of the equipment.
