Description

Technical Field

[0001] This utility model relates to the field of polyvinyl chloride raw material cleaning technology, and in particular to a polyvinyl chloride raw material particle cleaning device. Background Technology

[0002] Polyvinyl chloride (PVC) raw material granules, commonly referred to as PVC granules, are a basic raw material form of PVC resin during production or at the time of shipment. They are mainly used to produce various plastic products and are usually white or light yellow, odorless, and non-toxic powders or small granules. By adding different formulations of additives (plasticizers, stabilizers, etc.), these basic granules can be processed into final products that meet various application requirements. It is the second largest general-purpose plastic raw material in the world after polyethylene. Before hot-melt processing, it needs to be cleaned uniformly to remove impurities to ensure processing quality.

[0003] Currently, the main method for cleaning polyvinyl chloride (PVC) raw material granules is to place them in water and then use water flow to wash away impurities on the surface of the PVC raw material granules through agitation and friction. However, because PVC raw material granules are relatively light, when a large amount of raw material is added to water and stirred, a lot of material will float to the surface, making it difficult for the water flow to effectively contact and wash them. Therefore, the overall cleaning effect is not ideal, and the cleaning quality is difficult to guarantee.

[0004] Therefore, in response to the problem that the existing methods for cleaning polyvinyl chloride (PVC) raw material particles result in a large amount of material floating on the water surface, making it difficult for the water flow to effectively contact and rinse, thus leading to unsatisfactory overall cleaning results and difficulty in ensuring cleaning quality, a PVC raw material particle cleaning device can be designed.

The polyvinyl chloride (PVC) raw material particles are stirred and cleaned. Multiple soft bristles 10 are fixedly connected in a ring array on the inner wall of the mesh cylinder 6. First, the PVC raw material particles are added into the mesh cylinder 6. The lifting mechanism 2 controls the mesh cylinder 6 to rise, making it contact and adhere to the mesh-shaped cap 5. Then, the lifting mechanism 1 controls the lifting cap 3 to descend, causing the mesh-shaped cap 5 and the mesh cylinder 6 to fall below the water surface in the cleaning tank 1, completely submerging the PVC raw material particles. The stirring mechanism is then activated to stir and clean the PVC raw material particles. The soft bristles 10 assist in rubbing and removing impurities from the surface of the PVC raw material particles. Impurities and wastewater flow out from the mesh openings of the mesh cap 5 and the mesh cylinder 6, completing the cleaning of the PVC raw material particles.

[0025] Please see Figures 2-4In this embodiment, the lifting mechanism includes a fixed plate 401, a threaded rod 402, and a motor 403. The fixed plate 401 is fixedly connected to the upper right side of the cleaning tub 1. The threaded rod 402 is rotatably connected between the fixed plate 401 and the top plate 2. The right end of the lifting cover 3 is threadedly connected to the outside of the threaded rod 402. The motor 403 is fixedly connected to the upper right side of the top plate 2. The output shaft of the motor 403 is fixedly connected to the threaded rod 402. The motor 403 drives the threaded rod 402 to rotate. Starting the motor 403 drives the threaded rod 402 to rotate, and the threaded rod 402 drives the lifting cover 3 to move up and down. A fixed plate 11 is fixedly connected to the upper left side of the cleaning tub 1. A guide rod 12 is fixedly connected between the fixed plate 11 and the top plate 2. The left end of the lifting cover 3 is movably sleeved on the guide rod 11. On the outside of 2, during the lifting and lowering movement of the lifting cover 3, the guide rod 12 can provide a smooth and stable guide for its movement. The lifting mechanism 2 includes a threaded rod 801, a lifting block 802, and a motor 803. The threaded rod 801 is rotatably connected between the lifting cover 3 and the right end of the base plate 7. The lifting block 802 is threadedly connected to the outside of the threaded rod 801. The lifting block 802 is fixedly connected to the right end of the mesh cylinder 6. The motor 803 is fixedly connected to the upper end of the top plate 2. The top plate 2 has a through slot through which the motor 803 passes. The output shaft of the motor 803 is fixedly connected to the threaded rod 801. The motor 803 is used to drive the threaded rod 801 to rotate. When the motor 803 is started, it drives the threaded rod 801 to rotate. The threaded rod 801 drives the mesh cylinder 6 to move up and down through the lifting block 802.

[0026] Please see Figures 5-6In this embodiment, a guide rod 13 is fixedly connected between the left end of the lifting cover 3 and the bottom plate 7. A lifting block 14 is movably connected to the outer side of the guide rod 13. The lifting block 14 is fixedly connected to the left end of the mesh cylinder 6. When the mesh cylinder 6 moves up and down, the guide rod 13, in conjunction with the lifting block 14, can provide stable left and right guidance for the up and down movement of the mesh cylinder 6. The stirring mechanism includes a stirring shaft 901, a stirring rod 902, and a motor 903. The bottom of the lifting cover 3 is rotatably connected to the stirring shaft 901, and the outer side of the stirring shaft 901 is fixedly connected to the stirring rod 902. The upper end of the lifting cover 3 is fixedly connected to the motor 903. A power supply is provided on the top plate 2. The motor 903 passes through a slot, and its output shaft is fixedly connected to the stirring shaft 901. The motor 903 drives the stirring shaft 901 to rotate. When the motor 903 is started, it drives the stirring shaft 901, which in turn drives each stirring rod 902 to rotate, thereby agitating the water and polyvinyl chloride raw material particles for cleaning. The mesh cover 5 is movably sleeved on the upper outer side of the stirring shaft 901. Multiple connecting rods 15 are fixedly connected between the mesh cover 5 and the lifting cover 3. The mesh cover 5 and the lifting cover 3 are fixedly connected by multiple connecting rods 15, so as not to affect the rotation of the stirring shaft 901, while covering the mesh cylinder 6.

[0027] During operation, polyvinyl chloride (PVC) raw material granules are first added into the mesh cylinder 6. Using the second lifting mechanism, the second motor 803 is started to drive the second threaded rod 801 to rotate. The second threaded rod 801 drives the mesh cylinder 6 to rise through the first lifting block 802, so that it comes into contact with the mesh cover 5. Then, using the first lifting mechanism, the first motor 403 is started to drive the first threaded rod 402 to rotate. The first threaded rod 402 drives the lifting cover 3 to descend, so that the mesh cover 5 and the mesh cylinder 6 are lowered below the water surface in the cleaning tank 1, completely submerging the PVC raw material granules in the water. Then, using the stirring mechanism, the third motor 903 is started to drive the stirring shaft 901 to rotate. The stirring shaft 901 drives each stirring rod 902 to rotate, thereby stirring the cleaning water and PVC raw material granules, and stirring and cleaning the PVC raw material granules. The soft brush bristles 10 assist in rubbing and removing impurities from the surface of the PVC raw material granules. Impurities and sewage flow out from the mesh of the mesh cover 5 and the mesh cylinder 6, completing the cleaning of the PVC raw material granules.

[0028] Through the above steps, the device is equipped with a combinable mesh cover 5 and a mesh cylinder 6. The opening and closing of the two are controlled by a second lifting mechanism. The mesh cover 5 and the mesh cylinder 6 are lowered and submerged in the water in the cleaning tank 1 by a first lifting mechanism. Then, the stirring mechanism, together with the soft bristles 10 on the inner wall of the mesh cylinder 6, thoroughly and effectively cleans the added polyvinyl chloride (PVC) raw material particles. The PVC raw material particles can be completely submerged in the water for cleaning, avoiding floating on the water surface and not being able to receive the rinsing effect of the water flow. The cleaning of surface-adhered impurities is well handled, thus achieving efficient cleaning of the raw materials. The cleaning effect is also good, which effectively improves the quality of raw material processing and production. This solves the problem that the existing method of cleaning PVC raw material particles will cause a large amount of material to float on the water surface, making it difficult for the water flow to effectively contact and rinse, resulting in an unsatisfactory overall cleaning effect and difficulty in guaranteeing the cleaning quality.
