Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, and specifically relates to a filtering device for water treatment. Background Art

[0002] The filtration of water treatment is a key link in the water treatment process. It aims to remove suspended solids, particulate matter, dissolved substances, microorganisms and other impurities in water through the use of various filtration equipment and technologies to improve the quality and purity of water. When treating and filtering large particulate matter in water, by passing the water body through a sieve mesh, the purpose of screening out large particulate matter is achieved, and the mesh size of the sieve mesh can be adjusted according to needs to achieve different filtration effects. When treating and filtering large particulate matter in water through the sieve mesh, after a certain period of time, the large particulate matter in the water is intercepted by the mesh holes and blocked on the mesh holes. If not cleaned in time, it will reduce the water flow rate during water treatment, and seriously, it will cause blockage in the water treatment tank. For this reason, this application proposes a filtering device for water treatment to solve the above problems. Content of the Utility Model

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1-5 shown, the present invention provides a technical solution: a filtering device for water treatment, including a filtering box 1. There is an installation opening 2 on the top side of the filtering box 1, and a sealing plate 3 is arranged in the installation opening 2. The sealing plate 3 is installed in the installation opening 2 by bolts, and a first filter box 4 is installed on the bottom side of the sealing plate 3. There are two second filter boxes 5 arranged on the right side of the first filter box 4. The four sides of the first filter box 4 and the two second filter boxes 5 are all inclined and connected to the contracted shape of the right side opening. The four sides of the first filter box 4 and the two second filter boxes 5 are press-fitted in sequence from left to right. The first filter box 4 and the two second filter boxes 5 are connected by a plurality of mounting frames 6. The right side openings of the first filter box 4 and the two second filter boxes 5 are all in a contracted shape, and main filter meshes 7 are installed at the contracted openings on the right sides of the first filter box 4 and the two second filter boxes 5. The left and right ends of the filtering box 1 are respectively connected to an input pipeline and an output pipeline. Sewage enters the filtering box 1 and is filtered by the three main filter meshes 7 in sequence. The three main filter meshes 7 on the first filter box 4 and the two second filter boxes 5 become smaller in filter holes from left to right, so that impurities in the shape of large, medium and small particles can be filtered out in sequence. Groove openings 8 are formed on the four sides of the two second filter boxes 5, and side filter meshes 9 are installed in each groove opening 8. When the two main filter meshes 7 with relatively small filter holes on the second filter box 5 block a certain amount of impurities in the water, the water flow rate will be affected. At this time, the water flow will pass through the side channels of the second filter box 5 and flow to the right through the side filter meshes 9, which can avoid the normal water flow being blocked after being blocked by impurities on the two main filter meshes 7 and ensure the normal flow of water in the filtering box 1. When the water flows through the side filter meshes 9 on the four sides of the second filter box 5, the water flow rate detection module 11 can detect that the water flow rate in this area increases, realizing that the external control panel can receive in time that the main filter mesh 7 is blocked by impurities. By removing the sealing plate 3 through the installation opening 2, the main filter mesh 7 can be removed in time for cleaning or replacement. The four groove openings 8 on the two second filter boxes 5 are all arranged at the outermost edges of the sides. A water flow rate detection module 11 is installed on the outer sides of the two second filter boxes 5, and a sealing ring 10 is installed on the left edge of the first filter box 4.

[0024] The operation steps of the present invention are as follows:

[0025] The left and right ends of the filtering box 1 are respectively connected to an input pipeline and an output pipeline. Sewage enters the filtering box 1 and is filtered by the three main filter meshes 7 in sequence (as Figure 4As shown, after the main filter screen 7 with relatively small filter holes on the second filter box 5 blocks a certain amount of impurities in the water, its water flow rate will be affected. At this time, the water flow will pass through the side channel of the second filter box 5 and flow to the right through the side filter screen 9 (as Figure 5 shown), which can prevent the normal water flow from being blocked after being blocked by impurities on the two main filter screens 7, ensure the normal flow of water in the filter box 1, and when the water flows through the side filter screens 9 on the four sides of the second filter box 5, the water flow rate detection module 11 can detect that the water flow rate in this area increases, so that the external control panel can timely receive that the main filter screen 7 is blocked by impurities. By removing the sealing plate 3 through the installation opening 2, the main filter screen 7 can be removed in time for cleaning or replacement.
