Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to a corrosion-resistant, high-flow filter element. Background Technology

[0002] In the process of wastewater treatment, filters are often used to filter wastewater. Filter cartridges are important filter elements in filters. Among them, corrosion-resistant high-flow filter cartridges are high-performance filter elements designed specifically for handling large flow of chemically corrosive liquids. They are widely used in industries such as chemical, electroplating, electronics, and pharmaceuticals.

[0003] A search revealed CN218794449U, with an application date of April 21, 2022, disclosing a high-precision, high-flow-rate filter element, comprising an outer filter element and an inner filter element. The outer filter element has grooves on its surface, and a replacement mechanism is installed inside these grooves. One end of the outer filter element is connected to an installation mechanism, and the other end is fitted with a splicing mechanism. In this high-precision, high-flow-rate filter element, the filter cotton plate, activated carbon adsorption plate, and deodorizing plate are securely connected through the interaction of the slots and blocks. The filter cotton plate intercepts impurities in the filter, while the activated carbon adsorption plate adsorbs minute particles, increasing the filtration precision through dual filtration. Simultaneously, the deodorizing plate adsorbs odors, improving water quality. Furthermore, the use of anti-corrosion and anti-rust layers ensures that the inner filter element is covered with a protective film both inside and out, reducing damage from raw water.

[0004] However, it still has the following drawbacks in practical use: Existing corrosion-resistant high-flow filter cartridges use a splicing mechanism to connect and install the outer filter cartridge and the splicing filter cartridge. However, this method uses a mortise and tenon structure, which makes it difficult to separate the two after splicing, affecting work efficiency. 2. Existing corrosion-resistant high-flow-rate filter elements have their inner filter element, filtration mechanism, and protective mechanism all located inside the outer filter element on the support frame during use, which hinders the inspection and replacement of these components and results in low efficiency. Therefore, we provide a corrosion-resistant high-flow-rate filter element to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a corrosion-resistant, high-flow filter element. By setting a connecting component, the position of the U-shaped block is adjusted under the elastic action of the first spring, thereby achieving or releasing the limiting effect between the U-shaped block and the slot. This facilitates the quick disassembly and assembly of the outer filter element and the splicing of the filter element by the operator, resulting in high efficiency. Furthermore, by utilizing the limiting component, the height of the bracket end is adjusted under the elastic action of the second spring, which further facilitates the quick disassembly and assembly of the bracket by the operator, as well as the inspection and replacement of the components on it, making the operation convenient.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a corrosion-resistant high-flow filter element, including an outer filter element and a spliced ​​filter element disposed at its bottom. Connecting blocks are provided on both sides of the adjacent end faces of the outer filter element and the spliced ​​filter element. A first U-shaped groove is provided at both ends of the inner side of the connecting block. A second U-shaped groove is provided on the opposite end faces of the outer filter element and the spliced ​​filter element. A connecting component is provided inside the first U-shaped groove, and a limiting component is provided inside the second U-shaped groove. The connecting assembly includes a push plate disposed on the outside of the connecting block, and connecting columns arranged in an array from top to bottom on the inner wall of the push plate; The limiting assembly includes a top plate that is slidably mounted on the inner wall of the second U-shaped groove, and telescopic rods that are evenly spaced at the bottom of the top plate.

[0007] The present invention is further configured such that connecting grooves are provided on both sides of the adjacent end faces of the outer filter element and the splicing filter element, and slots are provided on both sides of the inner wall of the connecting grooves, and connecting blocks are installed inside the adjacent connecting grooves.

[0008] The present invention is further configured such that both the outer filter element and the spliced ​​filter element are equipped with a bracket inside, and the inner side of the bracket is provided with an inner filter element, a filtration mechanism and a protective mechanism.

[0009] The present invention is further configured such that the other end of the connecting column passes through the strip hole on the first U-shaped groove and is connected to the movable plate, and connecting rods are arrayed from top to bottom on one side wall of the movable plate.

[0010] The present invention is further configured such that the other end of the connecting rod slides through the sliding hole in the fixed plate and connects with the U-shaped block, and a first spring is sleeved on the outer wall of the connecting rod.

[0011] The present invention is further configured such that the first spring is located between the fixed plate and the U-shaped block, and the outer wall of the fixed plate is fixed on the inner wall of the first U-shaped groove.

[0013] This utility model has the following beneficial effects: This invention, by setting a connecting component, adjusts the position of the U-shaped block under the elastic action of the first spring, thereby achieving or releasing the limiting effect between the U-shaped block and the slot. This facilitates quick disassembly and assembly of the outer filter element and the splicing filter element by the staff, resulting in high efficiency. It solves the problem that existing corrosion-resistant high-flow filter elements use a splicing mechanism to connect and install the outer filter element and the splicing filter element, but this method uses a mortise and tenon structure, which makes it difficult to separate the two after splicing, thus affecting work efficiency.

[0014] This utility model, by setting a limiting component, adjusts the height of the bracket end under the elastic action of the second spring, thereby facilitating the quick disassembly and assembly of the bracket by the staff, and the inspection and replacement of the components on it. The operation is convenient and solves the problem that in the existing corrosion-resistant high-flow filter cartridges, the inner filter cartridge, filtration mechanism and protective mechanism on the bracket are all located inside the outer filter cartridge, which affects the inspection and replacement of the components and results in low efficiency.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1 Please see Figures 1 to 5 This utility model is a corrosion-resistant high-flow filter element, including an outer filter element 100 and a splicing filter element 200 disposed at its bottom. Connecting blocks 103 are provided on both sides of the adjacent end faces of the outer filter element 100 and the splicing filter element 200. A first U-shaped groove 103a is provided at both ends of the inner side of the connecting block 103. A second U-shaped groove 104 is provided on the opposite end faces of the outer filter element 100 and the splicing filter element 200. A connecting component 300 is provided inside the first U-shaped groove 103a. The connecting component 300 includes a push plate 301 disposed on the outside of the connecting block 103 and connecting posts 302 fixedly arranged from top to bottom on the inner wall of the push plate 301.

[0025] Specifically, both sides of the adjacent end faces of the outer filter element 100 and the spliced ​​filter element 200 are provided with connecting grooves 101, and the inner walls of both sides of the connecting grooves 101 are provided with slots 101a. The connecting block 103 is installed inside the adjacent connecting grooves 101. The inner side of the outer filter element 100 and the spliced ​​filter element 200 are provided with brackets 102, and the inner side of the brackets 102 is provided with an inner filter element, a filtration mechanism and a protective mechanism. The other end of the connecting column 302 passes through the strip hole on the first U-shaped groove 103a and is connected to the moving plate 303. Connecting rods 305 are arranged in an array from top to bottom on one side wall of the moving plate 303. The other end of the connecting rod 305 slides through the sliding hole on the fixed plate 304 and is connected to the U-shaped block 306. A first spring 305a is sleeved on the outer wall of the connecting rod 305. The first spring 305a is located between the fixed plate 304 and the U-shaped block 306. The outer wall of the fixed plate 304 is fixed on the inner wall of the first U-shaped groove 103a.

[0026] Furthermore, the outer filter element 100, the spliced ​​filter element 200, the inner filter element, the filtration mechanism, the protective mechanism, etc. are all existing technologies, so they will not be described in detail here. One end of the second U-shaped groove 104 is open. The connecting column 302 connects the push plate 301 and the moving plate 303, and the connecting rod 305 connects the moving plate 303 and the U-shaped block 306, which serves as a connection. Under the elastic action of the spring, it can drive the U-shaped block 306 to move.

[0027] The operation process of this embodiment is as follows: When installing the filter element inside the filter, the length of the filter element can be adjusted according to the length of the filter. The length of the filter element can be determined by the outer filter element 100 in conjunction with a certain number of spliced ​​filter elements 200. When connecting the outer filter element 100 and the spliced ​​filter elements 200, the outer filter element 100 and the spliced ​​filter elements 200 are first stacked together, and then the push plates 301 at both ends are pushed towards the middle. The push plates 301 are driven by the connecting column 302 to move the moving plate 303. The outer wall of the moving plate 303 is connected to the U-shaped block 306 through the connecting rod 305. Therefore, when the moving plate 303 moves, it will be connected to the U-shaped block 306. The rod 305 moves the U-shaped block 306 and squeezes the first spring 305a. At this time, the U-shaped block 306 moves into the first U-shaped groove 103a. Then, the connecting block 103 is installed in the connecting groove 101 on the outer filter element 100 and the spliced ​​filter element 200. Then, the force applied to the push plate 301 is stopped. At this time, under the elastic action of the first spring 305a, the U-shaped block 306 will pop out and be stuck into the slot 101a, completing the installation of the connecting block 103 and realizing the docking of the outer filter element 100 and the spliced ​​filter element 200. This makes it easy for workers to quickly disassemble and assemble the outer filter element 100 and the spliced ​​filter element 200, which is highly efficient.

[0028] Example 2 Please see Figure 3 and Figure 6 Based on Embodiment 1, unlike the first embodiment, a limiting component 400 is provided. The limiting component 400 includes a top plate 401 that is slidably installed on the inner wall of the second U-shaped groove 104, and telescopic rods 402 that are evenly spaced at the bottom of the top plate 401. This solves the problem that when existing corrosion-resistant high-flow filter cartridges are used, the inner filter cartridge, filtration mechanism, and protective mechanism on the bracket are all located inside the outer filter cartridge, which affects the maintenance and replacement of the components and results in low efficiency.

[0029] Specifically, a second spring 403 is sleeved on the outer wall of the telescopic rod 402, and both the second spring 403 and the telescopic rod 402 are located between the top plate 401 and the inner wall of the second U-shaped groove 104. The bottom end of the telescopic rod 402 is installed on the inner wall of the second U-shaped groove 104.

[0030] Furthermore, the telescopic rod 402 acts as a limit for the second spring 403, and under the elastic action of the second spring 403, it can drive the top plate 401 to move.

[0031] The operation process of this embodiment is as follows: When it is necessary to repair or replace the inner filter element, filter mechanism and protective mechanism on the bracket 102, first press the bracket 102 inward. The bracket 102 moves under force and squeezes the inner top plate 401. The top plate 401 moves under force and squeezes the telescopic rod 402 and the second spring 403. When the bracket 102 moves out of one end of the second U-shaped groove 104, it rotates counterclockwise. At this time, the bracket 102 will rotate to the other end of the second U-shaped groove 104, and then pass through that end of the second U-shaped groove 104. Simply remove the bracket 102 from the opening. Then, the inner filter element, filtration mechanism, and protective mechanism on the bracket 102 can be inspected and replaced. The same applies to installation. After pressing the four ends of the bracket 102 into the second U-shaped groove 104, rotate it clockwise and then stop applying force. Under the elastic action of the second spring 403, it will be pushed into the notch of the second U-shaped groove 104, which will play a limiting role and complete the installation of the bracket 102. This makes it easy for workers to quickly disassemble and assemble the bracket 102 and inspect and replace the components on it. The operation is convenient.
