[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0029] Referring to Figures 1-4 , a plastic extrusion granule screening device includes a sieve device body 1. A separation structure 2 is provided at the discharge port of the sieve device body 1. The separation structure 2 includes an inclined plate 201 installed at the discharge port of the sieve device body 1. The bottom wall of the inclined plate 201 is attached to a separation barrel 202. When the plastic granules are screened by the sieve device body 1, impurities fall into the discharge box below the sieve device body 1, and the plastic granules flow to the separation barrel 202 through the inclined plate 201. In addition, water is added to the inside of the separation barrel 202, and an appropriate amount of salt or other solutes is added to the water to increase the density of the water. When the density of the water is greater than or equal to the density of the plastic granules, the granules will suspend in the water, while some impurities will sink underwater.

[0030] The inner wall of the separation barrel 202 is communicated with a first connecting pipe 203. One end of the first connecting pipe 203 away from the separation barrel 202 is communicated with a second connecting pipe 204. The plastic granules floating on the water surface flow to the second connecting pipe 204 through the first connecting pipe 203. A separation box 205 is provided below the second connecting pipe 204. A separation plate 206 is installed on the inner wall of the separation box 205, and then flows to the separation box 205 through the second connecting pipe 204. The separation plate 206 is provided to separate the water and the plastic granules.

[0031] A filter pipe 207 is installed on the bottom wall of the second connecting pipe 204. The filter pipe 207 is located above the isolation box 205. The filter pipe 207 is a semi-circular filtering device. When particles and moisture pass through the second connecting pipe 204, the moisture falls into the lower isolation box 205 through the second connecting pipe 204, while the plastic particles fall onto the separation plate 206 through the filter pipe 207.

[0032] Baffles 208 are installed on the top wall of the inclined plate 201. The number of baffles 208 is two, and they are symmetrically installed on both sides of the inclined plate 201. By providing the baffles 208, it effectively prevents the plastic particles from detaching from the inclined plate 201 during the sliding process.

[0033] Refer to Figures 3-4 , a sealing structure 3 is provided on the separation structure 2. The sealing structure 3 includes an arc-shaped block 301 installed on the inner wall of the first connecting pipe 203. A connecting block 302 is installed on the bottom wall of the arc-shaped block 301. The connecting block 302 communicates with the inner wall of the arc-shaped block 301, and the outer wall of the arc-shaped block 301 is close to the outer wall of the separation barrel 202. The outer wall of the connecting block 302 is fixedly connected through the inner wall of the first connecting pipe 203. A motor 303 is installed on the bottom wall of the connecting block 302. The output end of the motor 303 is rotatably connected through the inner wall of the connecting block 302. A threaded rod 304 is installed at the output end of the motor 303. When the motor 303 is started, the output end of the motor 303 drives the threaded rod 304 to rotate.

[0034] A sealing block 306 is threadedly connected to the top end of the threaded rod 304. The outer wall of the sealing block 306 is slidably sealed with the inner wall of the arc-shaped block 301. A sliding rod 305 is installed on the inner bottom wall of the connecting block 302. The outer wall of the sliding rod 305 is slidably connected with the inner wall of the sealing block 306. The number of sliding rods 305 is two, and they are symmetrically distributed with the sealing block 306 as the center.

[0035] Start the motor 303 to drive the threaded rod 304 to rotate. The threaded rod 304 drives the sealing block 306 to slide on the sliding rod 305. When the sealing block 306 moves into the connecting block 302 through the threaded rod 304, the water flow and particles will flow to the second connecting pipe 204 through the connection between the arc-shaped block 301 and the connecting block 302. When the sealing block 306 moves into the arc-shaped block 301 through the threaded rod 304, the water flow and particle water are blocked at the outer wall position of the arc-shaped block 301.

[0036] Refer to Figures 1-2, a motor 4 is installed on the bottom wall of the separation barrel 202. A rotating rod 5 is installed at the output end of the motor 4. Stirring rods 6 are installed on the outer wall of the rotating rod 5. The outer wall of the stirring rod 6 is in contact with the inner wall of the separation barrel 202. There are multiple stirring rods 6, which are symmetrically distributed at equal intervals around the circumference of the rotating rod 5. Start the motor 4, the output end of the motor 4 drives the rotating rod 5 to rotate, and the rotating rod 5 drives the stirring rod 6 to rotate, rotating the water inside the separation barrel 202, which can not only clean the plastic to a certain extent, but also quickly transfer the plastic particles to the first connecting pipe 203.

[0037] The sealing block 306 can be closed in advance, and then the motor 4 is started to clean the plastic particles to a certain extent, and then the sealing block 306 is opened.

[0038] A water pump 7 is placed on the side of the separation barrel 202 away from the inclined plate 201. The water suction end of the water pump 7 is connected to a water inlet pipe 8. The outer wall of the water inlet pipe 8 is connected to the inner wall of the isolation box 205. The water outlet end of the water pump 7 is connected to a water outlet pipe 9. The outer wall of the water outlet pipe 9 is connected to the inner wall of the separation barrel 202. Start the water pump 7, and transfer the water inside the isolation box 205 to the water outlet pipe 9 through the water inlet pipe 8, and then transfer it to the inside of the separation barrel 202 through the stirring rod 6, so as to achieve the effect of water circulation.

[0039] Working principle:

[0040] When the plastic particles are screened by the screening device body 1, they flow into the separation barrel 202 through the inclined plate 201. The particles float on the water surface, and most of the impurities sink to the bottom because they are much lighter than the plastic particles. At this time, start the motor 4, and the motor 4 drives the rotating rod 5 and the stirring rod 6 to rotate, which not only cleans the plastic particles to a certain extent, but also speeds up the transfer of the plastic particles to the first connecting pipe 203, and is transferred to the second connecting pipe 204 through the first connecting pipe 203, and then falls into the isolation box 205. At the same time, the separation plate 206 separates the water and particles to a certain extent, and uses the water to effectively separate the plastic particles and impurities, thereby effectively improving the subsequent processing effect.

[0041] During the cleaning process of the plastic particles, start the motor 303, the motor 303 drives the threaded rod 304 to rotate, the threaded rod 304 drives the sealing block 306 to move upward, and is hermetically connected to the inner wall of the arc-shaped block 301. When the plastic particles are cleaned to a certain extent, then open the sealing block 306, and transfer the plastic and water to the isolation box 205, effectively improving the cleaning effect of the plastic particles.

[0042] Start the water pump 7, and transfer the water inside the isolation box 205 to the inside of the separation barrel 202 through the water outlet pipe 9 through the water inlet pipe 8, effectively achieving a certain water circulation effect and effectively improving the particle transfer ability.

[0043] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
