Description

Technical Field

[0001] This utility model relates to the field of wedge-shaped mesh filter cartridges, and in particular to large-scale wedge-shaped mesh filter cartridges for waste and sewage treatment. Background Technology

[0002] Wedge mesh filter cartridges are filter elements made of stainless steel wedge wire welded mesh. They feature high strength, high hardness, wear and corrosion resistance, uniform gaps, good permeability, and easy cleaning and backwashing. They are mainly composed of stainless steel wedge wires welded to support bars, with a filtration accuracy range of 30-800μm. They are widely used in screening and water treatment filtration in industries such as petroleum, chemical, pharmaceutical, food and beverage, metallurgy, and coal. Due to their wear and corrosion resistance, wedge mesh filter cartridges are also widely used in the environmental protection industry, and are also used in large-scale waste and sewage treatment processes for water treatment.

[0003] An existing wedge wire filter cartridge for wastewater treatment (publication number: CN217220472U) has at least the following drawbacks: In the aforementioned patent, a cleaning brush is used to clean the inner wall of the filter cartridge body, and the first motor and the second motor are used to rotate the cleaning brush while moving it up and down. However, the first motor and the second motor are located inside the filter cartridge body during operation, which means that they are in constant contact with wastewater, which will reduce the life of the motors due to corrosion and other reasons. They are also inconvenient to maintain. At the same time, the cleaning brush is not detachable, which makes it difficult to replace and makes it inconvenient to use, thus having certain limitations. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a large-scale wedge-shaped filter cartridge for waste and sewage treatment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0022] Reference Figures 1-4A large-scale wedge-shaped screen filter cartridge for waste and sewage treatment includes a filter cartridge body 1, with several brush heads 2 inside the filter cartridge body 1, and a cleaning assembly for cleaning the inside of the filter cartridge body 1. The cleaning assembly is located on the inner bottom surface of the filter cartridge body 1 and includes: a fixed pipe 3, which is fixedly installed on the inner bottom surface of the filter cartridge body 1; and a movable ring 4 that is movably sleeved on the outside of the fixed pipe 3. A fixed plate 5 is fixedly installed on one side of the inner side of the movable ring 4, and the fixed plate 5 is movably sleeved with the fixed pipe 3. The top of the fixed plate 5... The filter cartridge body 1 has a first threaded hole 6, and a threaded post 7 is threadedly connected to the inner circular wall of the first threaded hole 6. A rotating plate 8 is fixedly installed on the top surface of the threaded post 7, and several limiting posts 10 are fixedly installed on the bottom surface of the rotating plate 8. A rotating frame 14 is movably sleeved on the outer circular wall of the moving ring 4. Several limiting holes 9 are opened on the top surface of the rotating frame 14, and the limiting holes 9 are movably sleeved with the limiting posts 10. A drive motor 11 is provided on the top surface of the filter cartridge body 1. The bottom surface of the drive shaft of the drive motor 11 is fixedly installed with the rotating plate 8, and the brush head 2 is movably sleeved with the rotating frame 14.

[0023] In this embodiment, a support plate 12 is fixedly installed on the outer circular wall of the filter cartridge body 1. A fixing hole 13 is opened on the top surface of the support plate 12. The drive motor 11 is fixedly installed on the support plate 12. The drive shaft of the drive motor 11 is movably connected to the fixing hole 13. The top surface of the rotating frame 14 and the top surface of the brush head 2 are respectively provided with second threaded holes 15. The inner circular wall of the second threaded hole 15 is threaded with bolts 16. A fixing ring 17 is movably sleeved on the outside of the fixing tube 3. The fixing ring 17 is fixedly installed on the limiting post 10. The rotating plate 8 is made of stainless steel.

[0024] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When the user needs to use the filter cartridge body 1 and clean its interior, the drive motor 11 drives the rotating plate 8 to rotate, causing several limiting posts 10 and threaded posts 7 to rotate. The rotating limiting posts 10 then push the limiting holes 9 and the rotating frame 14 to rotate. The rotating frame 14 drives several brush heads 2 to rotate and clean the inner wall of the filter cartridge body 1. Simultaneously, the rotating threaded posts 7 and the first threaded hole 6 convert the rotational motion into linear motion, causing the fixing plate 5 to move inside the fixing tube 3. The moving fixing plate 5 then drives the moving ring 4 and the rotating frame 14 to move, thereby causing the several brush heads 2 to rotate. While rotating horizontally and moving up and down, the brush head 2 thoroughly cleans the interior of the filter cartridge body 1, ensuring a good cleaning effect. When the brush head 2 reaches the lowest or highest position, the drive motor 11 is started to rotate in the opposite direction. Furthermore, by rotating the bolt 16 out of the second threaded hole 15, the brush head 2 can be released from its fixation and removed from the outside of the rotating frame 14 for replacement. This achieves the comprehensive cleaning effect of the interior of the filter cartridge body 1. It allows multiple brush heads 2 to rotate and move up and down simultaneously, ensuring a good cleaning effect on the inner wall of the filter cartridge body 1. Moreover, the drive motor 11 is located outside the filter cartridge body 1, preventing it from being submerged in water and reducing the chance of damage from prolonged immersion in water. This facilitates maintenance, and the single-motor operation reduces costs. At the same time, the brush head 2 can be replaced, making it convenient to use and quite practical.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
