TECHNICAL FIELD

[0001] The application relates to the technical field of water filtration, in particular to a high-efficiency full-automatic scrap filtering device. BACKGROUND

[0002] An underwater pelletizer is a device used for processing high-molecular polymers, mainly used for cooling and cutting molten polymers into particles underwater. The water chamber is one of the core components of the underwater pelletizer, and its main function is to provide a cooling and conveying environment for the pelletizing process. The lower part of the water chamber is provided with a water inlet, and the upper part is provided with a drainage hole. Cooling water circulates through these channels, taking away the heat generated during the pelletizing process.

[0003] During the operation of the underwater pelletizer, the cooling water in the water chamber needs to be filtered to ensure the stability of the pelletizing process and the quality of the pellets. Currently, a filter screen is usually built into the cooling water conveying pipeline before the cooling water enters the pelletizer, and the cooling water is preliminarily filtered through the filter screen.

[0004] However, when filtering impurities in the cooling water through the filter screen, the impurities in the cooling water are easy to block the mesh holes of the filter screen, thereby affecting the filtering efficiency of the filter screen. Since the filter screen is built into the pipeline, it is difficult to disassemble and assemble, which makes it very inconvenient to clean the filter screen, thereby affecting the maintenance efficiency and operation stability of the equipment.

[0038] The embodiment of the present application discloses a high-efficiency full-automatic debris filtering device.

[0039] The application discloses a high-efficiency full-automatic debris filtering device which comprises a sedimentation tank 1, a filtering cylinder 2, a clean water transfer tank 3, a sewage filtering tank 4 and a debris removing assembly 5. The inside of the sedimentation tank 1 is connected with a water supply pipe 13 for feeding cooling water, the water inlet of the filtering cylinder 2 is communicated with the sedimentation tank 1, the water outlet of the filtering cylinder 2 is communicated with the clean water transfer tank 3, and the sewage filtering tank 4 is arranged below the filtering cylinder 2.

[0040] When the cooling water needs to be filtered, the cooling water to be filtered is fed into the sedimentation tank 1 through the water supply pipe 13. The cooling water is preliminarily filtered by sedimentation in the inside of the sedimentation tank 1. When the liquid level of the cooling water in the inside of the sedimentation tank 1 reaches a certain height, the cooling water overflows the sedimentation tank 1 and flows into the filtering cylinder 2, and the cooling water is further filtered by the filtering cylinder 2. The top of the clean water transfer tank 3 is provided with an opening, and the filtered cooling water flows into the clean water transfer tank 3 from the opening of the clean water transfer tank 3 under the action of gravity, and the filtered debris is attached to the outer wall of the filtering cylinder 2. The attached debris is cleaned by the debris removing assembly 5. Meanwhile, part of the cooling water which does not enter the filtering cylinder 2 flows on the filtering cylinder 2, washes the debris attached to the filtering cylinder 2, washes the debris accumulated on the debris removing assembly 5, and carries the debris to flow into the sewage filtering tank 4 for filtering, so as to be used for recycling filtering.

[0041] The top of one side of the sedimentation tank 1 is provided with a plurality of water outlets 11, and the filtering cylinder 2 is horizontally arranged below the water outlets 11. The water outlets 11 are arranged in plurality, and the cooling water in the inside of the sedimentation tank 1 flows onto the filtering cylinder 2 through the water outlets 11, and the plurality of water outlets 11 also filter the floating matters on the cooling water.

[0042] The position, close to the filtering cylinder 2, of the sedimentation tank 1 is provided with a placing groove 12, and the filtering cylinder 2 is partially arranged at the placing groove 12. The center line of the filtering cylinder 2 is located at the center line of the placing groove 12 and close to one side of the sedimentation tank 1. The side wall of the filtering cylinder 2 and the side wall of the sedimentation tank 1 are rotationally connected. After the cooling water flows from the water outlets 11 to the filtering cylinder 2, since the center line of the filtering cylinder 2 is located at the center line of the placing groove 12 and close to one side of the sedimentation tank 1, the top of the filtering cylinder 2 moves away from the sedimentation tank 1 when the filtering cylinder 2 rotates, so that the possibility of the filtered water flowing into the inside of the placing groove 12 is reduced.

[0043] The debris removing assembly 5 comprises a cylinder outer wall cleaning part 51 and a filter hole washing part 52. The cleaning side of the cylinder outer wall cleaning part 51 is in contact with the outer wall of the filtering cylinder 2, and the liquid spraying end of the filter hole washing part 52 is located at the position close to the inner wall in the inside of the filtering cylinder 2. When the debris attached to the outer wall of the filtering cylinder 2 is treated, the debris on the outer wall of the filtering cylinder 2 is scraped by the cylinder outer wall cleaning part 51, and the filter hole washing part 52 sprays from the inside of the filtering cylinder 2 to the outside, so as to wash away the blocked filter holes, so as to ensure the cleanness of the filtering cylinder 2 and the working stability of the filtering cylinder 2.

[0044] The outer wall cleaning part 51 comprises a mounting seat 511 and an elastic cleaning block 512.

The elastic cleaning block 512 is mounted on the mounting seat 511, so that the elastic cleaning block 512 of different sizes can be adapted according to the size of the filter cartridge 2. When the impurities are scraped off, the elastic cleaning block 512 is in contact with the outer wall of the filter cartridge 2, which reduces the possibility that the elastic cleaning block 512 deforms the filter cartridge 2 during work. In the embodiment of the application, the elastic cleaning block 512 is a sponge.

The flushing pipe 521 is arranged inside the filter cartridge 2, the end of the flushing pipe 521 penetrates through the end of the filter cartridge 2, the flushing pipe 521 is in rotational cooperation with the filter cartridge 2, and the flushing nozzle 522 is in communication with the flushing pipe 521. While the filter cartridge 2 rotates, water in the flushing pipe 521 is periodically sprayed out of the flushing nozzle 522 to flush away the blocked filter holes. Through the periodic flushing mode, water resources can be effectively saved.

[0046] The filter cartridge 2 rotates around the circumferential direction of the filter cartridge 2 axis by the first power source 6. The first power source 6 comprises a driven disc 61, a driving disc 62 and a motor 63. The driven disc 61 is arranged on the end of the filter cartridge 2, the driving disc 62 is in transmission cooperation with the driven disc 61, and the motor 63 shaft of the motor 63 is fixedly connected with the driving disc 62. When the filter cartridge 2 needs to rotate, the motor 63 drives the driven disc 61 to rotate through the driving disc 62, so as to improve the rotation speed stability of the filter cartridge 2 and reduce the possibility that the rotation speed of the filter cartridge 2 changes due to the water flow pressure of the filter cartridge 2.

[0047] The water outlet of the sewage filtering box 4 is in communication with the water supply pipe 13, and the water pump is communicated on the water supply pipe 13. The water filtered through the sewage filtering box 4 is sent into the water supply pipe 13 again by the water pump, so as to recycle the water. The sewage filtering box 4 is provided with an opening at the top, and the sewage filtering box 4 is provided with the water scraping assembly 7. The sewage is quickly flowed into the sewage filtering box 4 from the opening at the top of the sewage filtering box 4 through the water scraping assembly 7 by the water scraping assembly 7, so as to reduce the possibility of sewage overflow. In order to further facilitate the impurities to flow into the sewage filtering box 4, the top of the sewage filtering box 4 is provided with a slope for guiding the flow, so as to facilitate the water to flush the impurities into the sewage filtering box 4.

The auger or similar device can also be used to transport the sewage impurities. The end of the wiper plate 72 is provided with a sponge or other elastic material to reduce the possibility of damaging the sewage filtering box 4 when scraping the sewage. The second power source 8 is also a motor 63, and the motor 63 is in transmission connection with the conveying belt 71.

[0049] The implementation principle of the high-efficiency full-automatic debris filtering device is as follows: the cooling water first enters the sedimentation tank 1 through the water supply pipe 13, and removes the large-particle impurities through preliminary sedimentation and filtration. When the liquid level reaches a certain height, the cooling water overflows through the water outlet hole 11 at the top of the sedimentation tank 1 and uniformly flows into the horizontally placed filtering cylinder 2. During the rotation of the filtering cylinder 2, the cooling water is further filtered through the filter holes in the filtering cylinder 2, and the filtered clean water flows into the clean water transfer tank 3, and the impurities are attached to the outer wall of the filtering cylinder 2. At this time, the outer wall cleaning part 51 of the impurity removing assembly 5 scrapes off the attached impurities by using the elastic cleaning block 512, and the filter hole flushing part 52 flushes from the inside to the outside through the flushing pipe 521 and the spray head, so as to ensure the smoothness of the filter holes. Part of the cooling water that does not enter the filtering cylinder 2 flows outside the cylinder, flushes the impurities on the outer wall, and carries the impurities to flow into the sewage filtering box 4 below. The sewage filtering box 4 guides the impurities and sewage into the box through the wiper assembly 7, and the filtered water is delivered back to the water supply pipe 13 by the water pump, so as to realize the recycling. Through the synergistic effect of sedimentation, filtration, impurity removal and recycling, the device efficiently completes the purification treatment of the cooling water, ensures the stability of the water quality, and saves water resources.
