AI Technical Summary
The lack of sealing between the traditional filter element and the shell causes unfiltered fluid to penetrate into the downstream system, causing pollution or damage and increasing maintenance costs.
An industrial filter element is designed, using a sealing strip, annular sealing gasket and a beveled sleeve structure. The sealing performance at both ends of the filter element body is ensured through a multi-layer sealing system, including the close contact between the sealing strip and the inner wall of the shell, and the inclined design of the annular slot and sleeve increases the contact area and squeezes the sealing gasket to improve the sealing effect.
Effectively avoiding unfiltered fluid penetration, improving the sealing of the filter element, reducing maintenance costs, and enhancing the practicality of the filter element.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of filter elements, in particular to an industrial filter element. Background Art
[0002] The filter element is a purification device used to purify water resources so that they can be reused. It has filter material inside. The filter material's super filtering ability and pollution-holding capacity can effectively improve water purification efficiency.
[0003] Traditional designs often struggle to ensure a tight seal between the filter element and housing, which directly impacts the overall efficiency and stability of the filtration system. Poor sealing can allow unfiltered fluid to penetrate into downstream systems, causing contamination or damage and increasing maintenance costs. Utility Model Content
[0004] Aiming at the deficiencies in the prior art, the utility model provides an industrial filter element.
[0005] The embodiment of the present utility model provides an industrial filter element, comprising:
[0006] The outer shell is provided with a sealing cover, a filter element body is provided in the outer shell, end covers are fixedly provided at both ends of the filter element body, sealing strips are fixedly provided on the outer sides of the two end covers, a support rod is provided through the filter element body, annular sealing gaskets are fixedly provided on the outer sides of the two end covers, annular grooves are provided on the two annular sealing gaskets, both sides of the two annular grooves are inclined, a sleeve is fixedly provided on the inner bottom of the outer shell and the inner side of the sealing cover, and both sides of the outer end of the sleeve are inclined.
[0007] Furthermore, the inner bottom of the shell and the inner side of the sealing cover are both fixedly provided with limiting tubes, and the two ends of the support rod are respectively inserted into the limiting tubes on the same side.
[0008] Furthermore, a glass fiber reinforced plastic shell is fixedly provided on the outside of the filter element body.
[0009] Furthermore, a plurality of fan-shaped holes are provided through the two end covers, and the support rod is fixedly provided through the two end covers.
[0010] Furthermore, a water inlet is provided through the sealing cover, and a water outlet is provided through the bottom of the shell.
[0011] Furthermore, a bracket is fixedly provided on one side of the shell, and a plurality of mounting holes are penetrated through the bracket.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. Sealing strips are set up, and both sealing strips are pressed against the inner wall of the shell, thereby sealing the two ends of the filter element body.
[0014] 2. A sleeve and an annular sealing gasket are provided. Since the outer ends of the sleeve are inclined on both sides and the inner ends of the annular groove are inclined on both sides, the contact area between the sleeve and the annular sealing gasket can be increased after the sleeve is inserted into the annular groove. Moreover, under the extrusion of the sleeve, both sides of the inner end of the annular groove will bend and deform toward the middle and squeeze the inner and outer sides of the sleeve, thereby further improving the sealing effect at both ends of the filter element body and ensuring the sealing performance.
[0015] In summary, the utility model is provided with a sealing strip and an annular sealing gasket, which ensures the sealing performance between the two ends of the filter element body through a multi-layer sealing system, preventing unfiltered fluid from penetrating into the downstream system and causing pollution or damage, reducing maintenance costs and increasing practicality.

[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.
[0022] like Figures 1-4 As shown, the embodiment of the present utility model provides an industrial filter element, comprising:
[0023] The housing 1 has a bracket 2 fixedly disposed on one side thereof, the bracket 2 having a plurality of mounting holes therethrough, the bracket 2 being used for mounting the housing 1, and a water outlet being disposed at the bottom of the housing 1 for discharging water;
[0024] A sealing cover 3 is provided on the housing 1, and a sealing ring is fixedly provided on the inner top of the sealing cover 3. The sealing ring is tightly arranged against the top of the housing 1 to seal the housing 1 and the sealing cover 3. A water inlet is provided through the sealing cover 3 for water intake. A limiting tube 12 is fixedly provided on the inner bottom of the housing 1 and the inner side of the sealing cover 3 for limiting the position of the filter element body 4;
[0025] A filter element body 4 is provided in the outer shell 1, and a glass fiber reinforced plastic shell 5 is fixedly provided on the outside of the filter element body 4 to improve the overall strength of the filter element body 4, avoid extrusion deformation, and improve stability. End caps 6 are fixedly provided at both ends of the filter element body 4, and a plurality of fan-shaped holes are provided on the two end caps 6 for water circulation. Sealing strips 8 are fixedly provided on the outside of the two end caps 6. The two sealing strips 8 are both set against the inner wall of the outer shell 1 to play a sealing role. A support rod 7 is provided on the filter element body 4, and the support rod 7 is fixedly provided on the two end caps 6. The two ends of the support rod 7 are respectively inserted into the limiting tube 12 on the same side, thereby limiting the filter element body 4;
