Description

Technical Field

[0001] This utility model relates to the technical field of plastic granule processing equipment, specifically plastic granule processing equipment. Background Technology

[0002] Plastic granules are small granular materials made from plastic raw materials through processing such as crushing and melt extrusion. As a basic raw material for the production of many plastic products, they are widely used in packaging, construction, automobiles, and many other industries. In the recycling and reuse process of plastic granules, the quality and performance of the recycled plastic may be affected by various stains and impurities, making it unusable for direct production. At this point, cleaning equipment plays a crucial role. It can efficiently remove dust, oil, and other impurities from the surface of the plastic granules through physical or chemical methods, improving the purity of the plastic granules and making them meet the standards for reprocessing, thus ensuring the stable and reliable quality of the subsequently produced plastic products.

[0003] However, traditional plastic pellet cleaning equipment still has its drawbacks. For example, the cleaning effect of using a single stirring or spraying method is poor, the removal rate of oil stains on the pellet surface is low, and residual pollutants lead to insufficient pellet purity. Among them, the spraying method consumes a lot of water; while the stirring cleaning method, the stirring paddle is in direct contact with the pellets, which can cause the pellets to break or the edges to wear, affecting the pellet forming quality.

[0004] Therefore, we need to propose plastic pellet processing equipment. Utility Model Content

[0005] The purpose of this invention is to provide a plastic granule processing equipment in which the granules are cleaned by their own tumbling and friction in a closed cleaning chamber, without the need for direct contact with a stirring paddle. This reduces the granule breakage rate and the wear rate of the edges and corners, ensuring the integrity of the granule shape and guaranteeing the quality of subsequent processing and molding, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: Plastic pellet processing equipment includes: A base plate, on which a cleaning tank containing cleaning fluid is provided, and a drain outlet is provided at the lower end of the outer wall of one side of the cleaning tank; A top plate is positioned directly above the bottom plate. Support plates are symmetrically arranged at both ends of the bottom plate to support the top plate. A cleaning chamber is rotatably installed at the bottom of the top plate. A motor for driving the cleaning chamber to rotate is installed on one side of the bottom of the top plate. The cleaning chamber is a regular polygonal design. Each face of the regular polygon of the cleaning chamber is equipped with a mesh plate. The mesh plate allows the cleaning liquid to contact the plastic particles inside the cleaning chamber. One face of the cleaning chamber is equipped with an openable door panel for loading and unloading materials. A mesh plate is also installed inside the frame of the door panel.

[0007] Preferably, the support plate is arranged in an inverted L-shape, and hydraulic cylinders are symmetrically installed on the top of the support plate. The upper end of the hydraulic rod of the hydraulic cylinder passes through the support plate and is fixedly connected to the bottom of the top plate. The hydraulic cylinder controls the lower end of the cleaning chamber to be immersed in the cleaning pool or leave the cleaning pool.

[0008] Preferably, the bottom of the top plate is symmetrically provided with a fixing frame, the lower end of the fixing frame is installed with a bearing seat, and the center of both sides of the cleaning chamber is provided with a shaft, and the two sets of shafts are respectively inserted and fixed to the inner ring of the bearings of the two sets of bearing seats.

[0009] Preferably, a gear is installed at the output end of the motor, and a gear plate is installed at the end of the shaft near the motor side, with the gear and gear plate meshing together.

[0010] Preferably, a fan is installed on the top plate, and an air outlet pipe is connected to the air outlet end of the fan, with the air outlet pipe located directly above the cleaning chamber.

[0011] Preferably, the top plate is provided with an arc-shaped cover that covers the upper part of the cleaning chamber, and the air outlet pipe of the fan delivers airflow into the arc-shaped groove to dehydrate and dry the plastic particles in the cleaning chamber.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. When the regular polygonal cleaning chamber of this utility model rotates, the internal plastic particles turn over with the chamber and come into full contact with the cleaning liquid in the cleaning tank. The mesh plate design ensures that the cleaning liquid can penetrate the chamber and come into full contact with the particle surface. Combined with the mutual friction between the particles, the oil removal rate is high, the residual pollutants are reduced, and the particle purity is significantly improved.

[0013] 2. The cleaning solution is contained in a cleaning tank instead of continuous spraying. Only a small amount of liquid needs to be added during the cleaning process to replenish the evaporated or carried-away liquid, which greatly reduces water waste and sewage treatment costs. The particles are cleaned by their own tumbling and friction in the closed cleaning chamber, without the need for direct contact with the agitator. The particle breakage rate and edge wear rate are reduced, ensuring the integrity of the particle shape and guaranteeing the quality of subsequent processing and molding. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 This utility model provides a technical solution: Plastic pellet processing equipment includes: A base plate 1 is provided, and a cleaning tank 2 containing cleaning liquid is provided on the base plate 1. A drain outlet is provided at the lower end of the outer wall of one side of the cleaning tank 2. The top plate 4 is positioned directly above the bottom plate 1. Support plates 3 are symmetrically arranged at both ends of the bottom plate 1 to support the top plate 4. A cleaning chamber 5 is rotatably installed at the bottom of the top plate 4. A motor 8 for driving the cleaning chamber 5 to rotate is installed on one side of the bottom of the top plate 4. The cleaning chamber 5 is a regular polygonal design. Each face of the regular polygon of the cleaning chamber 5 is equipped with a mesh plate 6. The mesh plate 6 allows the cleaning liquid to contact the plastic particles inside the cleaning chamber 5. One face of the cleaning chamber 5 is equipped with an openable door panel 7 for loading and unloading. A mesh plate 6 is also installed inside the frame of the door panel 7.

[0018] The cleaning tank 2 on the base plate 1 contains cleaning fluid, and the top plate 4 is supported above the cleaning tank 2 by the support plate 3. The regular polygonal cleaning chamber 5 at its bottom can rotate under the drive of the motor 8. After the plastic granules are put into the cleaning chamber 5 through the openable door plate 7, the granules are turned over with the chamber when the chamber rotates. The cleaning fluid in the cleaning tank 2 enters the chamber through the holes of the mesh plate 6 and makes full contact with the surface of the granules. At the same time, the granules rub against each other, realizing the removal of oil and impurities.

[0019] Instead of traditional single stirring or spraying methods, it improves the cleaning effect by combining "immersion + tumbling friction"; the mesh plate 6 design ensures free flow of cleaning liquid, and the regular polygonal chamber allows for more thorough particle tumbling, solving the problem of incomplete cleaning in traditional methods.

[0020] For a preferred embodiment, please refer to Figure 1 : The support plate 3 is arranged in an inverted L-shape. Hydraulic cylinders 15 are symmetrically installed on the top of the support plate 3. The upper end of the hydraulic rod of the hydraulic cylinder 15 passes through the support plate 3 and is fixedly connected to the bottom of the top plate 4. The hydraulic cylinder 15 controls the lower end of the cleaning chamber 5 to be immersed in the cleaning pool 2 or to leave the cleaning pool 2.

[0021] Hydraulic cylinder 15 is powered by a hydraulic system. When the hydraulic rod of hydraulic cylinder 15 extends or retracts, it drives the top plate 4 to move up and down. Since the cleaning chamber 5 is installed at the bottom of the top plate 4, the movement of the top plate 4 will synchronously drive the cleaning chamber 5 to move up and down. When it is necessary to clean plastic particles, the hydraulic rod shortens, immersing the lower end of the cleaning chamber 5 into the cleaning solution in the cleaning tank 2. After cleaning, the hydraulic rod extends, lifting the cleaning chamber 5 away from the cleaning tank 2 for subsequent dehydration and drying operations. At the same time, the extension and retraction stroke of the hydraulic rod can precisely control the immersion depth (e.g., controlling the cleaning solution to cover 1 / 2 to 2 / 3 of the chamber).

[0022] The position of the cleaning chamber 5 can be flexibly adjusted, which facilitates the control of the cleaning process. The cleaning chamber 5 can come into contact with the cleaning fluid when needed for cleaning and leave the cleaning fluid after cleaning, thus improving the automation level and ease of operation of the equipment.

[0023] The multiple sets of hydraulic cylinders 15 are synchronously configured, sharing the same hydraulic power station (including an oil tank, a double gear pump, a relief valve, and a synchronizing valve). The high-pressure oil output from the hydraulic power station is diverted through the main oil circuit and then connected to the rodless chambers of the multiple sets of hydraulic cylinders 15 via multiple branch pipelines. The synchronizing valve (accuracy ≤0.5%) is installed at the front end of the branch pipeline to ensure that the oil flow and pressure entering the hydraulic cylinders on both sides are completely consistent.

[0024] For a preferred embodiment, please refer to Figure 1-3 : A fixing frame 9 is symmetrically arranged at the bottom of the top plate 4. A bearing seat 16 is installed at the lower end of the fixing frame 9. A shaft 10 is provided at the center of both sides of the cleaning chamber 5. The two sets of shafts 10 are respectively inserted and fixed to the inner rings of the bearings in the two sets of bearing seats 16. A gear 12 is installed at the output end of the motor 8. A gear 11 is installed at the end of the shaft 10 near the motor 8. The gear 12 and the gear 11 are meshed.

[0025] The shafts 10 on both sides of the cleaning chamber 5 are mounted on the fixed frame 9 at the bottom of the top plate 4 via bearing seats 16, forming a stable rotational support. The motor 8 drives the cleaning chamber 5 to rotate smoothly at a speed of 10-30 r / min by meshing with the gear disc 11 at the end of the shaft 10 via gear 12 (transmission ratio 1:5-1:10).

[0026] Ensure the stability of the cleaning chamber 5 during rotation to avoid localized wear of particles caused by chamber shaking; the meshing transmission of gear 12 ensures uniform rotation speed, consistent particle tumbling frequency, and improved cleaning uniformity.

[0027] For a preferred embodiment, please refer to Figure 1-3 : A fan 13 is installed on the top plate 4, and an air outlet pipe is connected to the air outlet end of the fan 13. The air outlet pipe is located directly above the cleaning chamber 5. An arc-shaped cover 14 is provided on the top of the top plate 4, which covers the upper part of the cleaning chamber 5. The air outlet pipe of the fan 13 delivers airflow into the arc-shaped groove to dehydrate and dry the plastic particles in the cleaning chamber 5.

[0028] After cleaning, the cleaning chamber 5 leaves the cleaning pool 2, and the blower 13 delivers airflow into the arc-shaped cover 14 through the air outlet pipe. The arc-shaped cover 14 forms a closed airflow space. The airflow passes through the mesh plate 6 and enters the cleaning chamber 5, making full contact with the rotating particles and removing surface moisture. At the same time, the centrifugal force generated by the rotation of the chamber assists in dehydration.

[0029] Integrated dehydration and drying functions eliminate the need for separate dehydration equipment; the combination of airflow and centrifugal force shortens the dehydration time and prevents particles from sticking together or deteriorating due to prolonged dampness.

[0030] After drying, rotate the side of the cleaning chamber 5 with the door panel 7 to face downwards, and open the door panel 7 with the container to unload the material.

[0031] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
