[0029] In addition, the terms "first" and "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0030] In the embodiments of the utility model, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting", "fixing" and the like should be understood in a broad sense, for example, can be fixed connection, can also be detachable connection, or be integrated; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, can be the communication inside two elements or the interaction relation between two elements. For ordinary skilled in the art, the specific meanings of the above terms in the embodiments of the utility model can be understood according to the specific circumstances.

[0031] In one embodiment of the utility model, as shown in Figures 1-4 A stable solid glue filter element is provided, which comprises end cover 100, pleated filter cartridge 200 and glue filling layer 300, the end cover 100 is provided with opening cavity 400 for curing glue material, the end of the pleated filter cartridge 200 extends into the opening cavity 400, the glue filling layer 300 is cured and formed in the opening cavity 400, wherein the inner wall of the opening cavity 400 is provided with tapered convex rib 500, the tapered convex rib 500 gradually narrows towards the opening direction of the opening cavity 400, and the edge of the glue filling layer 300 covers and fixes at least part of the tapered convex rib 500. Specifically, the number of the end cover 100 is two groups, and the two groups of end cover 100 are arranged at the two ends of the pleated filter cartridge 200.

[0032] During the process of curing the glue material in the open cavity 400, the end of the conical convex rib 500 extends into the cured glue layer 300, and the glue layer 300 is fixedly bonded with the conical convex rib 500 and the inner wall of the open cavity 400. Compared with the inner wall of the cavity in the end cover 100 in the prior art, the inner wall of the cavity is relatively smooth, and the glue layer 300 is easy to slide relative to the inner wall of the cavity in the end cover 100, which causes the glue layer 300 to fall off and affects the stability of the filter element. The stable glue-cured filter element provided in the embodiment of the utility model adopts the conical convex rib 500 extending into the cured glue layer, which greatly increases the contact area between the glue layer 300 and the end cover 100, effectively prevents the glue layer 300 and the pleated filter cartridge 200 from falling off, and improves the stability of the filter element.

[0033] As shown in Figures 1-4 Further, the end cover 100 comprises a base 110 and a sealing ring 120, both of which are arranged in a circular ring structure, the sealing ring 120 is sleeved on the outer side wall of the base 110, and the sealing ring 120 is detachably connected with the base 110. The outer side wall of the sealing ring 120 is provided with a clamping groove 130 for clamping a pre-installed position. In this embodiment, the filter element is used for natural gas filtering device, and the clamping groove 130 is clamped and matched with the edge of the pre-installed hole of the external frame.

[0034] As shown in Figures 1-4 Further, the sealing ring 120 is threadedly connected on the base 110. Threaded connection is conducive to conveniently detaching the base 110 from the sealing ring 120, and improves the operation convenience of the filter element.

[0035] As shown in Figures 1-4 Further, the outer side of the base 110 is provided with a raised thread ring 111, and the inner ring of the sealing ring 120 is provided with a thread groove capable of threadedly matching the raised thread ring 111. The outer diameter of the raised thread ring 111 gradually decreases in the direction towards the pleated filter cartridge 200. The thread ring with gradually decreasing outer diameter can smoothly enter the inner hole of the sealing ring 120 when the sealing ring 120 is installed, so that the thread groove can be quickly and smoothly butt-jointed with the thread ring of corresponding size, and the installation speed of the sealing ring 120 is effectively improved. Figure 4 As shown in Figure 4 The raised thread ring 111 comprises a first thread ring, a second thread ring and a third thread ring, which are sequentially and spacedly distributed on the outer side wall of the base 110 in the direction towards the pleated filter cartridge 200. The radius of the first thread ring is D1, the radius of the second thread ring is D2, and the radius of the third thread ring is D3, wherein D1>D2>D3.

[0036] As shown in Figures 1-4As shown, further, the middle position of the opening cavity 400 is provided with a positioning ring 410 extending from the bottom wall of the opening cavity 400 to the opening of the opening cavity 400, the inner circle of the positioning ring 410 is provided with an input hole 420, the end of the pleated filter cartridge 200 is clamped on the positioning ring 410, and the inner circle of the pleated filter cartridge 200 is in communication with the input hole 420. In this embodiment, the positioning ring 410 is used to preliminarily position the pleated filter cartridge 200, effectively preventing the pleated filter cartridge 200 from being deflected during the glue pouring and curing process, causing the curing position to be misaligned with the preset position and affecting the structural stability of the filter element.

[0037] As shown in Figures 1-4 further, the outer side wall of the positioning ring 410, the bottom wall of the opening cavity 400, and the inner side wall end face of the opening cavity 400 are all frosted surfaces, which is beneficial to improve the friction between the glue pouring layer 300 and the opening cavity 400 and the positioning ring 410, and further prevent the glue pouring layer 300 from falling off.

[0038] As shown in Figures 1-4 further, the bottom wall of the opening cavity 400 is provided with reinforcing ribs 430, one end of the reinforcing ribs 430 is fixedly connected with the inner wall of the opening cavity 400, and the other end of the reinforcing ribs 430 is fixedly connected with the bottom of the outer side wall of the positioning ring 410, wherein the number of the reinforcing ribs 430 is at least two groups. The reinforcing ribs are beneficial to improve the structural strength of the end cover 100. In this embodiment, the number of the reinforcing ribs 430 is six groups and is distributed on the bottom wall of the opening cavity 400, wherein the reinforcing ribs 430 protrude into the opening cavity 400, and a stress deformation compensation groove is formed between adjacent two groups of reinforcing ribs 430. During the glue pouring and curing process, the glue pouring layer 300 changes from a liquid state to a solid state and increases in volume, which will cause a certain extrusion to the end cover 100. The stress deformation compensation groove can effectively buffer the stress generated by the structural deformation caused by the extrusion, thereby improving the structural strength of the filter element.

[0039] As shown in Figures 1-4 further, the number of the tapered convex ribs 500 is multiple groups, and the multiple groups of tapered convex ribs 500 are distributed in a circle along the inner wall of the opening cavity 400. The use of multiple groups of tapered convex ribs 500 is beneficial to improve the stress balance of the glue pouring layer 300.

[0040] As shown in Figures 1-4As shown, further, a gap 600 is arranged between the bottom of the tapered convex rib 500 and the bottom of the open cavity 400, and the glue filling layer 300 solidified in the gap 600 is in close abutment with the bottom of the tapered convex rib 500. After the glue filling layer 300 is solidified in the gap 600, the tapered convex rib 500 can act as a reverse hook structure for stopping the glue filling layer 300 from being separated from the open cavity 400, effectively preventing the glue filling layer 300 from falling off and improving the stability of the filter core structure.

[0041] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
