Description

TECHNICAL FIELD

[0001] The utility model relates to a bottom extraction type filter element filter. BACKGROUND

[0002] The filter element filter is first entered into the coalescence layer with small filter hole diameter, and the small liquid drops are intercepted and adsorbed on the surface of the coalescence layer, and with the gas flowing forward, the small liquid drops are sent to the deep layer fiber, and after colliding with another small liquid drop, a large liquid drop is coalesced. With the liquid drop flowing forward, the coalescence process is repeated, and the filter hole diameter of the coalescence layer is continuously increased, and the diameter of the liquid drop is gradually increased. When the gravity of the liquid drop is greater than the buoyancy of the gas, the liquid drop falls off from the outermost liquid discharge layer, and the gas is discharged through the outer surface of the filter element.

[0003] The traditional filter element filter usually adopts a complete welding structure, and the filter element is not convenient to disassemble, which is not conducive to on-site maintenance and overhaul. SUMMARY

[0004] The utility model discloses a bottom extraction type filter element filter, which solves the problem of the traditional filter element filter, which usually adopts a complete welding structure, and the filter element is not convenient to disassemble, which is not conducive to on-site maintenance and overhaul.

[0005] To solve the above technical problems, the utility model provides the following technical scheme: a bottom extraction type filter element filter, which comprises a filter housing, an air inlet and an air outlet are formed on the two sides of the filter housing, a filter element is arranged between the air inlet and the air outlet, and installation structures are arranged on the two sides of the filter element.

[0006] The filter element is fixed in the housing through the installation structures.

[0007] Preferably, the installation structures comprise a mesh cage arranged on the outer periphery of the filter element, the bottom of the mesh cage is connected with a bearing plate through a support, and the outer periphery of the bearing plate is connected with the inner wall of the filter housing.

[0008] Preferably, a pressing plate is arranged at the bottom end of the mesh cage, and the pressing plate is connected with the bearing plate through a fixing bolt, so that the bearing plate fixes the filter element in the mesh cage through the pressing plate.

[0009] Preferably, two groups of channels for connecting the mesh cage are formed in the bearing plate, and a plurality of bolt holes for connecting the fixing bolts are arranged on the outer periphery of the channels.

[0010] Preferably, an end cover is arranged at the top end of the mesh cage, and a finger cone is arranged in the middle of the end cover.

[0011] Preferably, the top of the wire mesh cage is provided with a support frame, and the support frame is provided with two sets of connecting holes that cooperate with the finger cones, so that the wire mesh cage is connected to the support frame through the finger cones.

[0012] Preferably, the filter element has an internal stainless steel frame and protective cotton threads are provided on the outer periphery of the filter element.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The installation structure of this utility model allows for easy removal of the filter element after disassembling the bottom support plate using fixing bolts. The structure is simple, easy to disassemble, less prone to clogging, and requires minimal maintenance. It is commonly used in the pretreatment of fuel gas in gas turbines, removing lubricating oil leaking into compressed gas from the compressor, recovering lubricating oil from screw compressors, protecting adsorbents, molecular sieves, and membrane separation equipment, and protecting precision analytical and measuring instruments.

[0015] Compared to traditional filter cartridges with a fully welded structure, which involve cumbersome disassembly and low efficiency, the invented bottom-extraction filter cartridge simplifies the disassembly process and improves maintenance and repair efficiency.

[0016] Because the filter element can be pulled out from the bottom, on-site maintenance and repair are more convenient, especially in space-constrained environments, where this design can greatly reduce the difficulty of operation.

[0017] The design of the mesh cage, bearing plate, and pressure plate enhances the stability of the filter element, thereby improving the filter's service life and filtration efficiency.

[0018] The bottom-pull-out method of the filter element makes filter element replacement faster, without the need to disassemble the upper or side structure of the filter, reducing the time and complexity required for filter element replacement.

[0019] Because filter replacement is more convenient and quicker, maintenance costs are reduced, and downtime caused by maintenance is minimized. Attached Figure Description
