Description

Technical Field

[0001] This utility model relates to the field of water filter technology, specifically to a large-diameter W-shaped water filter. Background Technology

[0002] Water filters are used in water supply systems for high-flow-rate industrial equipment, such as power plants, steel mills, paper mills, and chemical plants.

[0003] It is well-known that water filters suffer from the problem of their filter screens gradually becoming clogged by debris in the filtered water during operation. In other words, the filter cannot completely and promptly remove debris from the screen during water delivery, leading to further clogging and requiring manual cleaning. Existing water filters are not easy to disassemble and maintain, and their flat filter screens are particularly prone to clogging, making them inconvenient to use and requiring improvement.

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a large-diameter W-shaped water filter, including a shell, one end of the shell is provided with a water inlet hole, the other end is provided with a water outlet hole, the top is provided with a mounting hole, the top of the shell is provided with a cover that mates with the mounting hole, and the cover is provided with a W-shaped filter screen that fits against the inner wall of the shell.

[0008] As an improvement, the housing and the cover are provided with a plurality of mutually cooperating first screw holes, and the first screw holes are provided with first bolts that can fix the cover to the housing.

[0009] As an improvement, the housing is provided with a circular plate that is fixedly connected to the W-shaped filter screen. The circular plate and the cover are provided with a second screw hole that matches each other. The second screw hole is provided with a second bolt that fixes the circular plate to the cover.

[0010] As an improvement, the outer side of the circular plate is provided with a sealing ring that mates with the housing and the cover.

[0011] As an improvement, the bottom of the W-shaped filter screen is fixed with an arc-shaped plate that fits against the inner wall of the housing.

[0012] (III) Beneficial Effects

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] 1. The W-shaped filter screen can block impurities in the water and can buffer and accommodate impurities to a certain extent, making the W-shaped filter screen less prone to clogging.

[0015] 2. The W-shaped filter screen is installed on the cover, which is attached to the housing by the first bolt, making it easy for personnel to disassemble and maintain. Attached Figure Description

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] Example 1

[0023] Combined with appendix Figure 1-4 A large-diameter W-shaped water filter includes a housing 1. One end of the housing 1 is provided with a water inlet 2, the other end is provided with a water outlet 3, and the top is provided with a mounting hole 4. The top of the housing 1 is provided with a cover 5 that mates with the mounting hole 4. The cover 5 is provided with a W-shaped filter screen 6 that fits against the inner wall of the housing 1. The W-shaped filter screen 6 blocks impurities. After being blocked by the W-shaped filter screen 6, the impurities will enter the bend of the W-shaped filter screen 6 and will not affect the operation of the filter.

[0024] The housing 1 and the cover 5 are evenly provided with a number of first screw holes 7 that cooperate with each other. The first screw holes 7 are provided with first bolts 8 that can fix the cover 5 to the housing 1, so as to facilitate the quick disassembly of the water filter by personnel.

[0025] The housing 1 is provided with a circular plate 9 that is fixedly connected to the W-shaped filter screen 6. The circular plate 9 and the cover 5 are provided with a second screw hole 10 that cooperates with each other. The second screw hole 10 is provided with a second bolt 11 that fixes the circular plate 9 to the cover 5, so as to facilitate personnel to disassemble and clean the W-shaped filter screen 6.

[0026] The outer side of the circular plate 9 is provided with a sealing ring 12 that mates with the shell 1 and the cover 5.

[0027] The bottom of the W-shaped filter screen 6 is fixed with an arc-shaped plate 13 that fits against the inner wall of the housing 1.

[0028] The working principle of this utility model is as follows: Water enters the water filter through the inlet hole 2, and after being filtered by the W-shaped filter screen 6 in the water filter, it is discharged from the outlet hole 3. After being filtered by the W-shaped filter screen 6, the impurities are washed by the water flow to the bending part of the W-shaped filter screen for storage, which will not affect the operation of the water filter.

[0029] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions, alterations, deletions of some features, additions of features, or recombinations of features to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the innovative principles of the present invention shall still fall within the scope of the technical solutions of the present invention.
