Technical Field

The utility model relates to the technical field of paper production, in particular to a sewage treatment filter which is easy to clean.

Background technique

Papermaking production refers to the process of making paper or cardboard from plant fibers (such as wood pulp, bamboo pulp, waste paper, etc.) through a series of physical and chemical treatments. A large amount of wastewater containing fibers, pigments, impurities and chemical agents will be generated in papermaking production. If these substances are directly discharged, they will cause pollution to the environment. However, sewage treatment filters are needed in the papermaking production process. The existing novel papermaking sewage treatment filter device (Announcement No.: CN212640110U) has a square groove at the bottom of the sewage treatment tank, and the square groove is tightly fitted into a square metal frame. The sewage treatment tank and the square metal frame are connected and fixed by cement slurry. A group of U-shaped hooks are welded to the square metal frame. A group of support columns are connected to the bottom of the sewage treatment tank. The support columns are connected by a pull rod. The pull rod and the support column form a support frame. A steel wire mesh is laid on the support frame. The mesh of the steel wire mesh is hooked by the U-shaped hook, and small stones are laid on the steel wire mesh. A water outlet is opened at the bottom of the sewage treatment tank, and the water outlet is connected to a water square pipe, and the water square pipe is connected to a pressure pump, and the pressure pump is connected to a water pipe. The utility model is used for papermaking wastewater treatment and filtration, and at least the following defects are exposed during use:

Detailed ways

The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

Embodiment: As shown in Figures 1 and 2, a sewage treatment filter that is easy to clean includes a body 1, and a water inlet 2 is opened on the upper left of the body 1. The water inlet 2 is convenient for connecting to a water inlet pipe 3, and the water inlet pipe 3 is convenient for sewage to pass through and enter the body 1. A coarse filter 5, a fine filter 6 and an activated carbon adsorption net 7 are arranged in sequence from top to bottom inside the body 1. When sewage enters the body 1, it will fall on the coarse filter 5, and the coarse filter 5 will filter the larger particles of impurities in the sewage. Then, after passing through the coarse filter 5, it will flow to the fine filter 6, and the fine filter 6 can filter the fine impurities, so that both larger and smaller particles of impurities fall on the coarse filter. 5 and the fine filter 6, the filtered sewage will pass through the activated carbon adsorption net 7, and the activated carbon adsorption net 7 will adsorb impurities in the sewage, thereby purifying the sewage. In addition, a drain pipe 4 is arranged at the lower right side of the body 1, and the treated sewage can be discharged through the drain pipe 4. In addition, a connecting plate 12 fixed by bolts is arranged in front of the body 1. By taking out the connecting plate 12, the coarse filter 5, the fine filter 6 and the activated carbon adsorption net 7 can be taken out, so that the coarse filter 5, the fine filter 6 and the activated carbon adsorption net 7 are taken out forward, and the fixing block is driven to be taken out from the fixing groove, so that the coarse filter 5, the fine filter 6 and the activated carbon adsorption net 7 can be cleaned;

As shown in FIGS. 2 to 3 , before the sewage enters the body 1, the motor 8 is turned on by the motor 8, the rotating rod 9, the fixed plate 10 and the scraper 11, and the motor 8 drives the rotating rod 9 to rotate, and then the rotating rod 9 drives the fixed plate 10 and the scraper 11 to move together. Since the scraper 11 is respectively located on the coarse filter 5 and the fine filter 6, the impurities in the sewage are easy to remain on the coarse filter 5 and the fine filter 6 before the sewage enters the body 1. Then, the impurities on the coarse filter 5 and the fine filter 6 can be scraped by the rotation of the scraper 11, so as to avoid more impurities clogging the coarse filter 5 and the fine filter 6 and affecting the fluidity of the water flow. Therefore, the scraper 11 is set to facilitate the impurities on the coarse filter 5 and the fine filter 6 to move with it, so as to prevent the coarse filter 5 and the fine filter 6 from being blocked.

As shown in Figures 4 to 6, through the provided collar 13, block 14, slot 15, limiting slot 16, positioning block 17 and positioning slot 18, when the water inlet pipe 3 needs to be disassembled, the water inlet pipe 3 is first rotated forward so that the water inlet pipe 3 drives the block 14 to move out of the limiting slot 16 and move to the slot 15, and at the same time drives the positioning block 17 to rotate in the positioning slot 18, and then when the block 14 is located at the slot 15, the water inlet pipe 3 can be taken out from the water inlet 2, and the block 14 can be pulled out from the slot 15, and then the positioning block 17 can be pulled out from the positioning slot 18, so that the water inlet pipe 3 can be taken out from the water inlet 2, and after taking it out, the water inlet can be cleaned. The water inlet pipe 3 is cleaned or replaced to prevent various solid particles, organic matter and microorganisms contained in the sewage from adhering to the inner wall of the water inlet pipe 3 after flowing through the water inlet pipe 3, so as to prevent the water inlet pipe 3 from being blocked. During installation, the water inlet pipe 3 drives the positioning block 17 on the sleeve ring 13 to be inserted into the positioning groove 18. At the same time, the clamping block 14 will be inserted into the clamping groove 15, and the clamping groove 15 will be located at the notch of the limiting groove 16. Then, the water inlet pipe 3 is rotated backward so that the clamping block 14 enters the bottom of the limiting groove 16. The positioning block 17 can also rotate in the positioning groove 18. The water inlet pipe 3 is fixed by the clamping block 14, and the positioning block 17 effectively ensures the stability of the installation of the water inlet pipe 3.

Working principle: The motor 8, rotating rod 9, fixed plate 10 and scraper 11 are arranged, and the motor 8 drives the rotating rod 9, fixed plate 10 and scraper 11 to rotate together. Since the scraper 11 is respectively located on the coarse filter 5 and the fine filter 6, when the sewage enters the body 1, the impurities in the sewage are easy to remain on the coarse filter 5 and the fine filter 6. Through the rotation of the scraper 11, the impurities on the coarse filter 5 and the fine filter 6 can be scraped to avoid more impurities clogging the coarse filter 5 and the fine filter 6 and affecting the fluidity of the water flow. Therefore, through the arrangement of the scraper 11, the impurities on the coarse filter 5 and the fine filter 6 are also convenient to move, and the coarse filter 5 and the fine filter 6 are prevented from being blocked; through the arrangement of the collar 13 and the block 14, the card slot 15, the limiting slot 16, the positioning block 17 and the positioning slot 18, the water inlet pipe 3 is rotated forward, so that the water inlet pipe 3 drives the card block 14 to move out of the limiting slot 16 and move to the card slot 15, and at the same time, the positioning block 17 is rotated in the positioning slot 18, and then the water inlet pipe 3 is taken out from the water inlet 2, so that the card block 14 is pulled out from the card slot 15, and the positioning block 17 is moved out from the positioning slot 18, and then the water inlet pipe 3 is taken out from the water inlet 2. After taking it out, the water inlet pipe 3 can be cleaned or replaced to prevent various solid particles, organic matter and microorganisms contained in the sewage from adhering to the inner wall of the water inlet pipe 3 after flowing through the water inlet pipe 3, so as to prevent the water inlet pipe 3 from being blocked.
