Description

Technical Field

[0001] This utility model relates to the technical field of filter structure of a polluted water pretreatment device, specifically to a water pollution pretreatment device with filtration function. Background Technology

[0002] Water pollution refers to water sources contaminated by garbage and impurities. This water is usually sent to treatment plants for treatment. Nowadays, in order to improve the treatment efficiency of sewage treatment plants, the polluted water is usually pre-treated during transportation. Filtration is the first and more important step in pre-treatment.

[0003] Filtration can trap large solids and small debris such as hair in water, ensuring that the water entering subsequent steps is free of large solid impurities. This avoids the impact of large solid impurities on subsequent process equipment. However, current filter structures are mostly stationary, causing impurities to accumulate on them. This requires frequent cleaning of the filter structure, which delays efficiency. Moreover, the filter structure needs to be disassembled for cleaning, allowing some impurities to flow into the next process. Therefore, a water pollution pretreatment device with filtration function is proposed. Utility Model Content

[0004] The technical problem this invention aims to solve is that current filter structures are mostly stationary, leading to the accumulation of impurities and requiring frequent cleaning, which reduces efficiency. Furthermore, the filter structure needs to be disassembled for cleaning, allowing some impurities to flow into subsequent processes. This invention provides a water pollution pretreatment device with filtration function, which allows for the disassembly and assembly of individual components without affecting the overall filtration effect, thus preventing debris from entering the next process during cleaning.

[0005] The technical solution adopted by this utility model to solve the technical problem is: a water pollution pretreatment device with filtration function, including a conveying pipe, the conveying pipe having a semi-circular structure, a fixed filter ring being provided inside the conveying pipe, a central shaft being fixedly connected to the center point of the fixed filter ring, movable filter rings being detachably connected to both sides of the fixed filter ring, the fixed filter ring and the movable filter rings forming a disc structure around a through hole, the center point of the movable filter ring being fitted and snapped together with the outer ring wall of the central shaft, and a cover plate being detachably connected to the top side wall of the conveying pipe.

[0006] As a preferred technical solution of this utility model, a plug is fixedly connected to one side wall of the fixed filter ring and near both sides. A slot is opened on the side wall of the fixed filter ring away from the plug. The slot and the plug are in the same position. The two side walls of the movable filter ring are connected to the fixed filter ring.

[0007] As a preferred technical solution of this utility model, the insert block has a cross-shaped structure, the slot is a structure corresponding to the insert block, the movable filter ring is inserted into the slot through the insert block and connected to the fixed filter ring, and the fixed filter ring and the movable filter ring form a disc structure through the insertion of the insert block and the slot.

[0008] As a preferred embodiment of this utility model, a limiting groove is uniformly provided on one side wall of the slot, and a movable groove is uniformly provided through the top side wall of the insert block. A positioning plate is movably inserted into the movable groove, and the positioning plate is an inclined structure corresponding to the limiting groove.

[0009] As a preferred technical solution of this utility model, the insert block has an inner groove in the side wall near the movable groove, a top plate is inserted into the inner groove, and one end of the positioning plate extends through the movable groove into the inner groove and fits against the top side wall of the top plate.

[0010] As a preferred technical solution of this utility model, a motor is detachably connected to one end of the central shaft, and fixed horizontal plates are detachably connected to both sides of the motor. One end of the fixed horizontal plate is fixedly connected to the inner wall of the conveying pipe.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figure 1-3 This utility model discloses a water pollution pretreatment device with filtration function, including a conveying pipe 1, which has a semi-circular structure. A fixed filter ring 2 is provided inside the conveying pipe 1. A central shaft 9 is fixedly connected to the center point of the fixed filter ring 2. Movable filter rings 10 are detachably connected to both sides of the fixed filter ring 2. The fixed filter ring 2 and the movable filter ring 10 form a disc structure around the through hole 8. The center point of the movable filter ring 10 is fitted with and snapped to the outer ring wall of the central shaft 9. A cover plate 7 is detachably connected to the top side wall of the conveying pipe 1.

[0018] A plug 12 is fixedly connected to one side wall of the fixed filter ring 2 near both edges. A slot 11 is formed on the side wall of the fixed filter ring 2 away from the plug 12. The slot 11 and the plug 12 are in the same position. The two side walls of the movable filter ring 10 are connected to the fixed filter ring 2. The plug 12 has a cross-shaped structure, and the slot 11 corresponds to the plug 12. The movable filter ring 10 is inserted into the slot 11 through the plug 12 and connected to the fixed filter ring 2. The fixed filter ring 2 is also connected to the fixed filter ring 2 through the plug 12 and the slot 11. The insert block 12 and the movable filter ring 10 form a disc structure. A limiting groove 17 is evenly opened on one side wall of the slot 11. A movable groove 15 is evenly opened through the top side wall of the insert block 12. A positioning plate 16 is movably inserted into the movable groove 15. The positioning plate 16 is an inclined structure corresponding to the limiting groove 17. An inner groove 13 is opened in the side wall of the insert block 12 near the movable groove 15. A top plate 14 is inserted into the inner groove 13. One end of the positioning plate 16 passes through the movable groove 15, extends into the inner groove 13, and fits against the top side wall of the top plate 14.

[0019] The technical effect of this solution is as follows: First, the top plate 14 is pulled out from the inner tank 13, and then the corresponding movable filter ring 10 is pulled outward by force. This allows the corresponding movable filter ring 10 to be removed, making it easy to clean. In this way, it is not necessary to disassemble the entire filtration equipment, ensuring that the sewage is effectively filtered while cleaning. Moreover, individual cleaning and disassembly are more convenient, improving the convenience and practicality of the application.

[0020] One end of the central shaft 9 is detachably connected to a motor 4. Both sides of the motor 4 are detachably connected to fixed horizontal plates 3. One end of the fixed horizontal plate 3 is fixedly connected to the inner wall of the conveying pipe 1. A through hole 8 is provided on the cover plate 7. The through hole 8 is sleeved on the outside of the fixed filter ring 2. A storage box 5 is fixedly connected to one side wall of the conveying pipe 1. A lever 6 is fixedly connected to the upper side wall of the conveying pipe 1. The lever 6 has an L-shaped structure, and one end of the lever 6 is attached to one side wall of the fixed filter ring 2 and the movable filter ring 10.

[0021] The technical effects of this solution are as follows: a storage box 5 is fixed on one side of the conveying pipe 1, and a baffle 6 is fixed on the top side wall of the conveying pipe 1. When the filter structure passes the baffle 6, the debris on its surface will be scraped off and enter the storage box 5 along the baffle 6, achieving a self-cleaning effect and reducing the frequency of manual disassembly and cleaning of the filter structure. The cover 7 can prevent water from spilling out, and the through hole 8 can ensure the normal rotation of the filter structure.

[0022] Specifically, when this utility model is in use, the starting motor 4 drives the central shaft 9 to rotate, which in turn drives all the movable filter rings 10 to rotate via the central shaft 9 and the fixed filter ring 2. Because the outer ring walls of the fixed filter ring 2 and the movable filter ring 10 are in contact with the inner wall of the conveying pipe 1, they can fully block the sewage passing through, ensuring effective filtration and interception of the sewage. As the fixed filter ring 2 and the movable filter ring 10 rotate, different movable filter rings 10 can be used for filtration, reducing the excessive accumulation of impurities in a single part. The set-in baffle 6 can also clean the debris on the surface of the movable filter ring 10 and the fixed filter ring 2. When it is necessary to clean the filtration equipment, simply pull out the top plate 14 and then pull the corresponding movable filter ring 10 outward. Under pressure, the positioning plate 16 will retract into the inner groove 13, ensuring that the movable filter ring 10 can be pulled out smoothly. This ensures effective filtration and facilitates cleaning of the filtration structure. During the cleaning process, the motor 4 stops working, and the filtration equipment is switched to manual rotation.

[0023] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0024] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
