Description

Technical Field

[0001] This utility model relates to the field of waste plastics, specifically to a wet crushing device for waste plastics that is easy to export. Background Technology

[0002] The more formal term for waste plastics is post-consumer plastic waste, which refers to discarded plastic products after consumption or use. Plastics also generate waste and scrap during synthesis, molding, processing, and distribution; this plastic waste is also called pre-consumer plastic waste. A wet crushing plant for waste plastics is a type of crushing equipment specifically designed for processing waste plastics. However, it's worth noting that wet crushing technology is generally more suitable for processing organic waste; its applicability to materials like waste plastics, which are relatively hard and have unique chemical properties, may be limited.

[0003] Existing wet crushing equipment for waste plastics is not convenient for discharge. During the existing wet crushing process, waste plastic fragments may stick together due to the presence of moisture and impurities, causing blockage at the discharge port, which makes discharge difficult. At the same time, cleaning the blockage requires additional time and manpower, increasing operating costs.

[0004] Therefore, it is necessary to invent a wet crushing device for waste plastics that is easy to export in order to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a waste plastic wet crushing device that facilitates discharge. When waste plastic is fed into the crushing chamber, the crushing mechanism crushes the wet plastic. The crushed plastic falls onto the first set of filter plates for filtration. At this time, the servo motor switch is turned on, driving the transmission rod and the external connecting block to continuously strike and move the filter plates up and down. This not only achieves the effect of filtration and screening but also facilitates the discharge of the plastic from the filter plate surface onto the right-side conveying assembly for transporting the crushed plastic. This solves the problem mentioned in the background art: existing waste plastic wet crushing devices are inconvenient for discharge. In the existing wet crushing process, waste plastic fragments may stick together due to the presence of moisture and impurities, causing blockage at the discharge port, making discharge difficult. Furthermore, cleaning the blocked discharge structure requires additional time and manpower, increasing operating costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste plastic wet crushing device that is easy to export, including a crushing box for wet crushing of waste plastic;

[0007] A feeding hopper is located above the crushing chamber for feeding materials. A crushing mechanism is fixedly installed inside the crushing chamber for crushing. A water trough is provided on the bottom side of the inside of the crushing chamber.

[0008] A screening and discharge mechanism is installed inside the crushing chamber for screening and discharge. The screening and discharge mechanism includes a filter plate and a servo motor.

[0010] Preferably, the crushing mechanism includes a first drive motor, which is fixedly installed on the rear side of the crushing box. A first crushing roller is fixedly connected to the output end of the first drive motor. A second drive motor is fixedly installed on the other side of the rear of the crushing box. A first gear is fixedly connected to the output end of the second drive motor. A second gear is externally meshed with the first gear. A second crushing roller is fixedly connected to the rear side of the first gear and the second gear.

[0011] Preferably, the front two sides of the filter plate are fixedly connected to movable shafts, the rear two sides of the filter plate are slidably connected to telescopic rods, the lower part of the telescopic rods is fixedly connected to a fixing block, the fixing block is fixedly connected to the crushing chamber, and the upper part of the telescopic rods is sleeved with a spring.

[0012] Preferably, the filter plate is inclined inside the crushing chamber, and the filter plate is rotatably connected to the crushing chamber via a movable shaft.

[0013] Preferably, the connecting block is elliptical, and the transmission rod is fixedly connected to the other side of the connecting block.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-6The illustrated waste plastic wet crushing device includes a crushing chamber 1 for wet crushing of waste plastics.

[0029] The feed hopper 2 is located above the crushing box 1 and is used for feeding. The crushing mechanism 3 is fixedly installed inside the crushing box 1 for crushing. A water trough 7 is provided on the bottom side inside the crushing box 1.

[0030] The screening and discharge mechanism 4 is set inside the crushing box 1 for screening and discharge. The screening and discharge mechanism 4 includes a filter plate 401 and a servo motor 406. The filter plate 401 is set inside the crushing box 1. The servo motor 406 is fixedly set on the rear side of the crushing box 1. The output end of the servo motor 406 is fixedly connected to a transmission rod 407. The transmission rod 407 is fixedly connected to a connecting block 408. A fixed frame 5 is fixedly connected to the right side of the crushing box 1. The fixed frame 5 is equipped with a conveying component 6 inside.

[0031] The spraying mechanism 8 is located inside the crushing chamber 1 and is used for spraying. When the waste plastic is put into the crushing chamber 1, the crushing mechanism 3 crushes the wet plastic. After crushing, the plastic falls onto the first set of filter plates 401 for filtration. At this time, the servo motor 406 is turned on to drive the transmission rod 407 and the external connecting block 408 to continuously knock and drive the filter plate 401 to move up and down. This not only achieves the effect of filtration and screening, but also facilitates the conveying of the crushed plastic to the right conveying component 6.

[0032] like Figure 2 and Figure 3 As shown, the crushing mechanism 3 includes a first drive motor 301, which is fixedly mounted on the rear side of the crushing chamber 1. The output end of the first drive motor 301 is fixedly connected to a first crushing roller 302. A second drive motor 303 is fixedly mounted on the other side of the rear of the crushing chamber 1. The output end of the second drive motor 303 is fixedly connected to a first gear 304. The first gear 304 is externally meshed with a second gear 305. The rear sides of the first gear 304 and the second gear 305 are fixedly connected to a second crushing roller 306. By turning on the switch of the first drive motor 301, the first crushing roller 302 is driven to rotate. Then, by turning on the switch of the second drive motor 303, the first gear 304 is driven to rotate. The meshing of the first gear 304 drives the second gear 305 to rotate relative to each other. At the same time, the rotation drives the two sets of second crushing rollers 306 to rotate relative to each other. The three sets of crushing rollers simultaneously crush the waste plastic, thereby improving the crushing effect.

[0033] like Figure 2 , Figure 4 and Figure 5As shown, movable shafts 402 are fixedly connected to both sides of the front end of the filter plate 401, and telescopic rods 403 are slidably connected to both sides of the rear end of the filter plate 401. A fixing block 404 is fixedly connected to the lower part of the telescopic rod 403, and the fixing block 404 is fixedly connected to the crushing box 1. A spring 405 is sleeved on the upper part of the telescopic rod 403. When the filter plate 401 is pushed by the connecting block 408, the filter plate 401 moves up and down outside the telescopic rod 403. When the filter plate 401 loses the pressure of the connecting block 408, the spring 405 outside the telescopic rod 403 squeezes and rebounds the filter plate 401 back to its original position, thereby causing the filter plate 401 to shake up and down, which facilitates the discharge of crushed plastic.

[0034] like Figure 2 and Figure 4 As shown, the filter plate 401 is inclined inside the crushing chamber 1. The filter plate 401 is rotatably connected to the crushing chamber 1 via the movable shaft 402. The filter plate 401 is inclined inside the crushing chamber 1, which facilitates the discharge of crushed plastic. At the same time, the filter plate 401 rotates inside the crushing chamber 1 via the movable shaft 402, so that the filter plate 401 shakes up and down to screen during the tilting process, which also facilitates the discharge of broken plastic.

[0035] like Figure 2 and Figure 5 As shown, the connecting block 408 is elliptical, and the transmission rod 407 is fixedly connected to the other side of the connecting block 408. When the servo motor 406 is turned on, it drives the transmission rod 407 and the two sets of connecting blocks 408 to rotate. Since the connecting block 408 is elliptical, when the protruding side of the connecting block 408 contacts the bottom of the filter plate 401 during rotation, it can drag the filter plate 401 upward, thereby causing the filter plate 401 to sway up and down in the crushing chamber 1, which facilitates the discharge of crushed plastic.

[0036] like Figure 1 , Figure 2 and Figure 6 As shown, the spraying mechanism 8 includes a water pump 801, which is installed inside the water tank 7. A water pipe 802 is fixedly connected to the outside of the water pump 801, and the other end of the water pipe 802 is located below the feed hopper 2. Spray heads 803 are installed on the outside of the water pipe 802. During the wet crushing process, by turning on the switch of the water pump 801 inside the water tank 7, the water in the water tank 7 is transported from the water pipe 802 to the spray head 803 and sprayed out, thereby spraying the plastic and the crushing mechanism 3. This can effectively prevent the first crushing roller 302 and the second crushing roller 306 from overheating due to long-term operation, reduce wear and tear on the rollers, and suppress the generation of particles. Spraying can also achieve the effect of cleaning fragments, ensuring that the crushed plastic particles are purer.

[0037] The working principle of this practical system is as follows: First, connect the external power supply. Then, feed waste plastic from the feed hopper 2 into the crushing chamber 1. At this time, turn on the first drive motor 301 to drive the first crushing roller 302 to rotate. Next, turn on the second drive motor 303 to drive the first gear 304 to rotate. The first gear 304 meshes with the second gear 305 to rotate relative to each other. Simultaneously, the rotation drives the two sets of second crushing rollers 306 to rotate relative to each other. The three sets of crushers crush the waste plastic at the same time, thereby improving the crushing effect. During the crushing process, turn on the water pump 801 inside the water tank 7 to deliver water from the water pipe 802 to the spray head 803 to spray onto the plastic and the crushing mechanism 3. This can effectively prevent the first crushing roller 302 and the second crushing roller 306 from overheating due to prolonged operation, reduce wear and tear on the rollers, and suppress the generation of particulate matter. The spraying can also clean the fragments, ensuring that the crushed plastic particles are purer. Afterward, the crushed plastic falls onto the first set of filter plates 401 for filtration. When the servo motor 406 is switched on, it drives the transmission rod 407 to connect with the external connecting block 408. The connecting block 408 is elliptical, so when the convex side of the connecting block 408 contacts the bottom of the filter plate 401 during rotation, it can push the filter plate 401 upward. When the filter plate 401 is pushed by the connecting block 408, the filter plate 401 moves up and down outside the telescopic rod 403. When the filter plate 401 is no longer squeezed by the connecting block 408, the spring 405 outside the telescopic rod 403 squeezes and rebounds the filter plate 401 back to its original position. The filter plate 401 is moved up and down in place, which facilitates the discharge of the crushed plastic. The crushed plastic on the surface of the filter plate 401 falls onto the conveying assembly 6 on the right. By turning on the switch of the conveying assembly 6, the plastic is conveyed and discharged. There is another set of filter plates 401 below the filter plate 401, which can screen plastic particles of different sizes. Finally, after all the crushed plastic has been discharged, all electrical switches are turned off and the external power supply is cut off. This completes the use of the waste plastic wet crushing device that facilitates discharge.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
