Description

Technical Field

[0001] This utility model relates to the field of combined filter element technology, specifically a combined filter element. Background Technology

[0002] A modular filter cartridge is an innovative design that integrates multiple filter materials or functional layers into a single filter cartridge structure to achieve multi-stage filtration, improve filtration efficiency, and extend service life. Its core lies in combining filter layers of different materials or functions to work together to complete tasks such as coarse filtration, fine filtration, and adsorption. It is suitable for scenarios such as water treatment, air purification, and industrial filtration.

[0003] According to patent publication CN215962484U published on the Chinese Patent Network, a combined filter element for water treatment equipment includes a housing mechanism and a cleaning mechanism. The housing mechanism includes a housing body, guide rails, a filter plate, a lifting plate, filter elements, and a drain pipe. Guide rails are fixedly installed on both the left and right sides inside the housing body. A filter plate is fixedly installed inside the housing body. A lifting plate is fixedly installed between the two guide rails. Two filter elements are fixedly installed on the outer surface of the filter plate. This combined filter element for water treatment equipment is activated by an electric push rod. The function box and lifting plate are pushed. The left and right sides of the lifting plate are inside the guide rail. Under the push of the electric push rod, the lifting plate descends. Then the cleaning column surrounds the filter element inside the cleaning column. Then the motor is started. The motor drives the rotating rod to rotate. The rotation of the rotating rod drives the rectangular gear to rotate. Then the rectangular gear drives the driven gear that meshes with it to rotate. However, the assembly and disassembly of this combined filter element is not convenient. It is difficult to easily disassemble and replace individual filter elements during maintenance. After long-term use, the filter element can only be disassembled as a whole for cleaning and replacement, which cannot meet the user's needs.

[0004] Therefore, it is necessary to redesign and modify the modular filter element to effectively prevent its difficulty in disassembly and assembly. Utility Model Content

[0028] refer to Figure 4 The scrubbing assembly 3 includes a short strip 301. The left side of the short strip 301 is fixedly connected to the surface of the screw 206. A scrubbing strip 302 is provided on the right side of the short strip 301. The scrubbing strip 302 is located on the surface of the filter element body 1. A positioning rod 303 is fixedly connected to the top of the short strip 301. A cleaning brush 304 is fixedly connected to the left side of the scrubbing strip 302. The left side of the cleaning brush 304 is in contact with the surface of the filter element body 1.

[0029] As a technical optimization of this utility model, by setting the brushing component 3, the surface of the filter element body 1 can be cleaned, thereby improving the cleanliness of the filter element body 1.

[0030] refer to Figure 2 A top ring 4 is fixedly connected to the top of the filter element body 1. The top ring 4 is located on the surface of the movable sleeve 207. A sealing ring 5 is fixedly connected to the surface of the top ring 4. There are two sealing rings 5.

[0031] As a technical optimization of this utility model, by setting the top ring 4 and the sealing ring 5, the top of the filter element body 1 can be sealed, thereby improving the sealing performance of the filter element body 1.

[0032] refer to Figure 2 A handle 6 is fixedly connected to the top of the top ring 4. The surface of the handle 6 is provided with anti-slip texture. There are several handles 6, which are evenly distributed.

[0033] As a technical optimization of this utility model, by setting a handle 6, it is easier for users to pull the filter element body 1, thus improving the ease of pulling the filter element body 1.

[0034] refer to Figure 1 A sealing ring 7 is fixedly connected to the top of the bottom frame 201, and the top of the sealing ring 7 contacts the bottom of the filter element body 1.

[0035] As a technical optimization of this utility model, by setting a sealing ring 7, the gap between the bottom frame 201 and the filter element body 1 can be sealed, thereby improving the sealing performance of the bottom frame 201.

[0036] refer to Figure 3 The surface of the movable sleeve 207 is fixedly connected with a retaining strip 8, and the inside of the inner sleeve 202 is fixedly connected with a retaining plate 9, with the retaining strip 8 located inside the retaining plate 9.

[0037] As a technical optimization of this utility model, by setting the card strip 8 and the card plate 9, the movable sleeve 207 can be limited to prevent the movable sleeve 207 from rotating, thereby improving the moving stability of the movable sleeve 207.

[0038] The working principle and usage process of this utility model are as follows: When cleaning or replacing a single filter element, the operator can slowly rotate the screw 206. Under the precise engagement of the threads, the rotational motion of the screw 206 is converted into the linear downward displacement of the moving sleeve 207. During this process, the clamping plate 9 and the clamping strip 8 are tightly engaged to form a reliable limiting structure, effectively preventing the moving sleeve 207 from rotating with the screw 206, ensuring that the moving sleeve 207 only moves vertically. As the moving sleeve 207 descends smoothly, the rotating plate 208 connected to its bottom is driven downward and begins to rotate downward around the fixed fulcrum. The rotation of the rotating plate 208 further drives the positioning plate 209 connected to it to move inward. The horizontal displacement causes the positioning plate 209 to gradually disengage from the top ring 4. At this time, the operator only needs to lift the handle 6 upwards, and the handle 6 will drive the single top ring 4 and the filter element body 1 connected to it to move upwards together, thereby easily realizing the disassembly of the single filter element body 1. In addition, while rotating the screw 206 to drive the moving sleeve 207 to move downwards, the screw 206 also forms a transmission relationship with the brush strip 302 through the short strip 301, driving the brush strip 302 to rotate synchronously. The rotation of the brush strip 302 then drives the cleaning brush 304 to rotate. The bristles of the cleaning brush 304 are closely attached to the surface of the filter element body 1, and the impurities and dirt attached to the surface of the filter element are effectively removed through rotational friction, achieving the cleaning effect.

[0039] In summary, this modular filter cartridge allows for the individual assembly and disassembly of each cartridge using a modular assembly. This facilitates easy removal and replacement of individual cartridges during maintenance. After prolonged use, the entire filter cartridge can be cleaned and replaced without requiring complete disassembly, thus meeting user needs and solving the problem of difficult assembly and disassembly.
