Technical Field

[0001] This utility model relates to the field of cross-linked polyvinyl chloride washing technology, and in particular to an integrated cross-linked polyvinyl chloride automatic washing and filtration device. Background Technology

[0002] Cross-linked povidone is a widely used tablet disintegrant in the pharmaceutical field. It is often used as a drug carrier, stabilizer, and binder, and its usage is enormous. In its production process, washing cross-linked povidone is a key step in obtaining high-purity products.

[0003] When washing crospovidone, the common method is to add the crospovidone raw material to be washed into the washing tank at the same time as the detergent, and then mix the two in the washing chamber. However, the existing washing equipment has a single stirring method, which cannot ensure that the detergent and crospovidone are evenly mixed in the washing tank. As a result, some crospovidone does not fully contact and react with the detergent, making it difficult for the purity of the washed product to meet the ideal standard. Therefore, an integrated automatic washing and filtering device for crospovidone is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing washing equipment, which uses a single stirring method and cannot ensure that the detergent and cross-linked polyvinyl chloride are evenly mixed in the washing tank, resulting in some cross-linked polyvinyl chloride failing to fully contact and react with the detergent, making it difficult for the purity of the washed product to meet the ideal standard. Therefore, an integrated cross-linked polyvinyl chloride automatic washing and filtering device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An integrated cross-linked polyvinyl chloride automatic washing and filtration device includes a filter box, a washing tank inside the filter box, a stirring rod inside the washing tank, a first rectangular plate fixedly connected to the inner wall of the filter box, a shaking plate below the first rectangular plate, a shaking mechanism inside the filter box that drives the washing tank to shake via the shaking plate, and a filter screen below the washing tank.

[0017] A first rectangular plate is fixedly connected to the inner wall of the filter box 1. A shaking plate 4 is provided below the first rectangular plate. A shaking mechanism is provided inside the filter box 1 to drive the washing tank 2 to shake through the shaking plate 4. Through the shaking mechanism, while the washing tank 2 is washing the cross-linked polyvinyl ketone raw material, the washing tank 2 is shaken back and forth to further improve the mixing efficiency.

[0018] A filter screen 5 is installed at the bottom of the washing tank 2. The cross-linked polyvinyl chloride is filtered through the filter screen 5 after mixing. The cross-linked polyvinyl chloride liquid is separated through the filter screen 5, while the solid particles are trapped on the filter screen 5, thus achieving solid-liquid separation.

[0019] The shaking mechanism includes a first rotating rod 7 rotatably connected to a first rectangular plate. One end of the first rotating rod 7 is fixedly connected to a rotating plate 8. A rectangular block 9 is fixedly connected to the bottom of the first rectangular plate. The rectangular block 9 has a first rectangular opening 10.

The circular block 11 is in contact with the side of the rotating plate 8. A connecting plate 12 is fixedly connected to the bottom of the shaking plate 4. One end of the connecting plate 12 is fixedly connected to the top of the washing tank 2. The first rotating rod 7 causes the rotating plate 8 to rotate, and then through the circular block 11, the shaking plate 4 slides back and forth in the first rectangular opening 10, thereby driving the washing tank 2 to shake through the connecting plate 12. It should be noted that the rotating plate 8 is roughly triangular in shape, with three rounded corners and three concave sides, so that the rotation of the rotating plate 8 can drive the circular blocks 11 on both sides to move back and forth.

[0020] A second drive motor 13 is installed on the top of the washing tank 2. A second rotating rod 14 is rotatably connected to the top of the washing tank 2 and fixedly connected to the output end of the second drive motor 13. The stirring rod 3 is fixedly connected to the second rotating rod 14. By rotating the second rotating rod 14, the stirring rod 3 stirs the cross-linked polyvinyl ketone raw material inside the washing tank 2.

[0021] A feed pipe is fixedly connected to the bottom of the washing tank 2. A solenoid valve is installed on the feed pipe. After mixing is completed, the solenoid valve controls the cross-linked polyvinyl ketone to fall from the feed pipe onto the filter screen 5.

[0022] The inner wall of the filter box 1 is provided with a rectangular groove, and the filter screen 5 is located in the rectangular groove. A second rectangular plate 15 is fixedly connected to one side of the filter screen 5, and a handle is fixedly connected to one side of the second rectangular plate 15. The filter screen 5 in the rectangular groove can be easily removed by using the handle on one side of the second rectangular plate 15 to process solid particles.

[0023] The filter box 1 has a receiving cavity 16, and symmetrically distributed springs 17 are fixedly connected in the receiving cavity 16. One end of the spring 17 is fixedly connected to a limiting block 18. The top of the second rectangular plate 15 has a limiting groove 19, and the limiting block 18 is located in the limiting groove 19. A toggle plate 20 is fixedly connected to one side of the limiting block 18. The side of the filter box 1 has a second rectangular opening 21, and the toggle plate 20 is located in the second rectangular opening 21. Through the elasticity of the spring 17, the limiting block 18 is locked in the limiting groove 19 at the top of the second rectangular plate 15, thereby limiting the second rectangular plate 15 and preventing the filter screen 5 from falling out of the rectangular groove.

[0024] The bottom of the filter box 1 has a discharge port. The washing tank 2 is fixedly connected to the first inlet pipe and the second inlet pipe 22. The two sides of the filter box 1 have a third rectangular opening. The first inlet pipe and the second inlet pipe 22 are respectively located in the second rectangular opening 21 on both sides. The first inlet pipe is used to add cross-linked polyvinyl acetate raw material into the washing tank 2, and then the second inlet pipe 22 is used to add detergent into the washing tank 2. The second rectangular opening 21 allows the first inlet pipe and the second inlet pipe 22 to move back and forth with the washing tank 2. After mixing and filtering, the cross-linked polyvinyl acetate is discharged from the discharge port for recycling.

[0025] The shaking mechanism also includes a first drive motor 6 installed on the top of the first rectangular plate. The specific model and specifications of the first drive motor 6 and the second drive motor 13 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0026] The working principle of this utility model: Crosslinked polyvinyl acetate raw material and detergent are fed into washing tank 2 through the first feed pipe and the second feed pipe 22, respectively. Then, the second drive motor 13 drives the second rotating rod 14 to rotate, the second rotating rod 14 drives the stirring rod 3 to rotate, and the stirring rod 3 stirs the crosslinked polyvinyl acetate raw material and detergent. At the same time, the first drive motor 6 drives the first rotating rod 7 to rotate, the first rotating rod 7 drives the rotating plate 8 to rotate, the rotating rod drives the two circular blocks 11 to rotate while moving them back and forth, the circular blocks 11 drive the shaking plate 4 to move back and forth in the first rectangular opening 10, the shaking plate 4 drives the connecting plate 12 to move back and forth, and the connecting plate 12 then drives the washing tank 2 to shake back and forth in the filter box 1. After washing, cross-linked polyvinyl chloride is allowed to fall from washing tank 2 onto filter screen 5 via a solenoid valve. After the solid particles are filtered by filter screen 5, the cross-linked polyvinyl chloride is discharged from the outlet. A container is placed below the outlet for recycling. Finally, the toggle plate 20 is turned on, causing it to move upward within the second rectangular opening 21. The spring 17 contracts until the limit block 18 moves out of the limit groove 19. Then, the filter screen 5 can be removed from the rectangular groove through the handle and the second rectangular plate 15 to process the solid particles on the filter screen 5.
