Description

Technical Field

[0001] The utility model belongs to the technical field of environmental protection and water treatment, and specifically relates to an anti-flushing assembly and a drum-type precision filter. Background Art

[0002] Due to its advantages such as compact structure, large filtration area, and simple operation, the drum-type precision filter is widely used in the water treatment field. However, after long-term use of the traditional drum-type filter, impurities are likely to accumulate on the surface of the filter media, resulting in an increase in filtration resistance and a decrease in filtration efficiency. It is necessary to stop the machine for cleaning regularly, which affects the production continuity and filtration effect.

[0003] The utility model with the publication number CN218923972U relates to the filtration field in the production and molding process of polymer materials, and discloses a full-automatic drum backwashing filter, which includes a protective cover. Inside the protective cover, there is a filter body. The filter body includes a main body, a filter drum, a guide column, an inlet flange, and an outlet flange. The inlet flange and the outlet flange are fixedly installed on both sides of the main body. The filter drum is rotatably installed inside the main body. A support cylinder is arranged inside the filter drum. The end of the support cylinder is fixedly connected to the inlet flange. A guide column is arranged inside the support cylinder. An intermediate connecting part is inserted into the guide column. Inside the outlet flange, there is a transmission gear fixedly connected to the end of the filter drum. A transmission gear meshing with the transmission gear is rotatably installed inside the main body. The transmission gear is connected to the motor. Four cavities communicating with the inlet flange are opened inside the main body.

[0004] However, the above patent still has the following problems: During the cleaning process of the drum filter by the backwashing structure, there will still be some tiny residues attached to the water filter mesh holes, which are difficult to completely remove. The residues will gradually accumulate, affecting the subsequent filtration effect and even shortening the service life of the filter. When it is necessary to deeply clean or replace the backwashing structure, it is often necessary to disassemble the entire filter body or a large number of components, which not only increases the maintenance difficulty and time cost, but also may cause equipment damage due to improper operation. The lack of a quick-disassembly design also makes daily maintenance cumbersome and is not conducive to the long-term stable operation of the equipment. It is more inconvenient to clean the backwashing structure subsequently.

[0005] In view of this, the present utility model is specifically proposed. Summary of the Utility Model

[0042] Working principle: First, the first fixing plate 10 is fixed to the bottom of the second fixing plate 11 through a quick-release structure (the second threaded groove 16 and the limit bolt 17 on the third fixing plate 15). The quick-release structure allows for quick installation and disassembly, facilitating maintenance and component replacement. The limiting structure (the clamping of the first clamping plate 13 and the first clamping groove 14, and the limit bolt 17 passing through the second threaded groove 16 and being helically installed in the first threaded groove 12) further enhances the structural stability. Start the servo motor 19, and its output shaft drives the threaded rod 20 to rotate through a coupling. The rotation of the threaded rod 20 causes the threaded sleeve 23 to move on the threaded rod, thereby driving the slider 22 to move along the guide rod 21, ensuring the smooth movement and precise positioning of the slider 22. The movement of the slider 22 drives the connecting plate 24 and the cleaning brush 25 to move. The cleaning brush 25 closely adheres to the outer surface of the drum filter 29 for cleaning, removing dirt and impurities on the surface. Water is introduced into the water tank 26 from an external water tank through the water delivery pipe 28. The water in the water tank 26 is evenly sprayed onto the outer surface of the drum filter 29 through the spray nozzles 27, further flushing away the dirt and impurities remaining after cleaning. The drum filter 29 rotates driven by a driving device for liquid filtering operation. The wastewater generated during the filtering process is discharged into the sewage trough plate 30 through the hole at one end of the drum filter 29 and the drain pipe 32, realizing the collection and centralized treatment of wastewater. The drain pipe 32 not only serves for wastewater discharge but also plays a supporting role for the fifth fixing plate 31, and the fifth fixing plate 31 limits the drum filter 29 to ensure its stability during operation.
