Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically to a pre-coated filtration device with an air blowing structure. Background Technology

[0002] A filter is a device or equipment used to separate, screen, or purify substances. Through specific filter media, such as filter screens, membranes, or cartridges, it can block or retain larger particles, impurities, and suspended solids, while allowing smaller particles or fluids to pass through. Filters play an important role in many fields, such as filtering impurities from liquids or gases in industrial production to ensure the normal operation of production processes and product quality.

The residue is usually blown off by injecting compressed gas. However, existing filter devices require welding two ports, one for liquid outlet and one for air inlet. This welding process is complex, and the filter device is prone to leakage and has poor sealing. Utility Model Content

[0027] Embodiment 1

[0028] As Figs. 1 to 3 shown in the present application, the embodiments of the present application provide a pre-coated filtering device with a blowing structure, which comprises a filtering tank body 1 provided with an outlet end 11 and a three-way pipe body 2 connected by a first pipe body 21, a second pipe body 22 and a third pipe body 23; one end of the first pipe body 21 is in communication with the outlet end 11; the second pipe body 22 is provided with a first diaphragm 3; the first diaphragm 3 is arranged vertically to the inner wall of the second pipe body 22, and the sealing side of the first diaphragm 3 faces the communication position of the second pipe body 22 with the first pipe body 21 and the third pipe body 23.

[0029] More preferably, in the embodiments provided in the present application, the filter tank body 1 is a filter tank body commonly known in the prior art, the lower end of the filter tank body 1 is provided with a liquid inlet 12 and a filter residue discharge port 13, the filter tank body 1 is provided with a filter element, and the upper end cover of the filter tank body 1 is provided with an outlet end 11. The liquid discharged from the liquid inlet 12 is discharged from the outlet end 11.

[0030] A three-way pipe body 2 is connected to the outlet end 11 by flange connection. The three-way pipe body 2 is in the shape of T. The first pipe body 21 and the third pipe body 23 are integrally formed into a branched pipe, and the second pipe body 22 is vertically arranged between the first pipe body 21 and the third pipe body 23. The end of the third pipe body 23 not connected to the first pipe body 21 is connected to the liquid discharge pipe of the filter system. The end of the second pipe body 22 not connected to the first pipe body 21 is connected to the gas outlet of the external gas blowing device for providing high-pressure gas.

[0031] A first diaphragm 3 is arranged inside the second pipe body 22. The first diaphragm 3 is arranged in the second pipe body 22 close to the first pipe body 21 and the third pipe body 23. The first diaphragm 3 is a one-way diaphragm. The pressure side of the first diaphragm 3 is away from the direction of the first pipe body 21 and the third pipe body 23. The first diaphragm 3 is made of elastic material, including but not limited to rubber and plastic.

[0032] In use, the liquid to be filtered enters from the lower end of the filter tank body 1. The filtered liquid enters the first pipe body 21 from the outlet end 11. Due to the one-way nature of the first diaphragm 3, the liquid can only be discharged through the third pipe body 23. After the filtration is completed, the external gas blowing device inputs high-pressure gas through the second pipe body 22. The high-pressure gas opens the first diaphragm 3 and enters the filter tank body 1 through the first pipe body 21, and blows off the filter residue remaining on the filter element.

[0033] In this embodiment, by arranging the three-way pipe body 2 at the outlet end 11 of the filter tank body 1, the generation of multiple welding interfaces is avoided, the production process of the equipment is simplified, the sealing performance and flow consistency are improved, and the simple structure is easy to produce and manufacture.

[0034] Embodiment 2

[0035] Further, on the basis of the above-mentioned embodiment 1, as shown in Fig. 2 The first diaphragm 3 is arranged in the second pipe body 22 in a detachable manner. A first groove is arranged on the inner wall of the second pipe body 22. The first diaphragm 3 is embedded in the first groove. The first diaphragm 3 is arranged perpendicular to the central axis of the second pipe body 22. In use, when the first diaphragm 3 needs to be replaced, only the connection between the second pipe body 22 and the gas blowing pipe needs to be disconnected. The first diaphragm 3 is taken out from the pipe opening of the second pipe body 22. A new first diaphragm 3 is embedded to complete the replacement of the first diaphragm 3.

[0036] In the embodiment, the quick replacement of the first diaphragm 3 is realized by mounting the detachable first diaphragm 3 in the second pipe body 22, the efficiency of equipment maintenance is improved, and the simple structure is easy to produce and manufacture.

[0037] Embodiment 3

[0038] Further, on the basis of the above-mentioned embodiment 1, as shown in Fig. 2 and Fig. 3 The first diaphragm 3 is composed of eight diaphragm petals, each of which is provided with a reinforcing rib 31, and the eight reinforcing ribs 31 form a circular pie structure with a smaller diameter than the first diaphragm 3, and the outer side walls of the eight reinforcing ribs 31 abut against the second pipe body 22. When the liquid flows through the first diaphragm 3, the reinforcing rib 31 is used for strengthening and supporting, and the risk of liquid leakage is reduced.

[0039] In the diameter direction of the first diaphragm 3, from the outer circle of the first diaphragm 3 to the center, the thickness of the eight reinforcing ribs 31 gradually decreases, that is, there is a conical recess on the circular pie structure composed of the eight reinforcing ribs 31. When the gas is input, the setting of the recess makes the first diaphragm 3 more easily opened by the gas.

[0040] In the embodiment, by providing the reinforcing rib 31 on the first diaphragm 3, the use stability of the first diaphragm 3 is improved, the risk of liquid leakage is reduced, and at the same time, the recess structure is provided on the eight reinforcing ribs 31, the threshold value of the opening of the first diaphragm 3 is reduced, and the efficiency of the gas opening the first diaphragm 3 is improved.

[0042] The above-mentioned only for the preferred embodiments of the present application, and does not limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included in the protection scope of the present application.
