DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following descriptions, the descriptions of well - known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0024] As Figures 1-4As shown in the figure, a tear-resistant filter material proposed by the present utility model, the filter material group includes an A filter layer 11, a support layer 12 and a B filter layer 13 arranged in a laminated manner, and the A filter layer 11 and the B filter layer 13 are formed on the upper and lower end faces of the support layer 12;

[0025] The edge sealing structure includes an edge sealing member 21 sleeved on the edge of the filter material group, and a wrapping groove 22 is provided on the end face of the edge sealing member 21 attached to the whole combination;

[0026] A through hole is provided at the attachment part of the edge sealing member 21 and the filter material group, and the locking mechanism includes a two-way bolt 32 arranged in the through hole, an A locking member 31 is screwed on the upper end of the two-way bolt 32, and a B locking member 33 is screwed on the lower end.

[0027] In this embodiment, during the use of the integrally formed filter material group, the parts that are prone to warping and separation at the edges are protected by the edge sealing mechanism. The edge sealing member 21 wraps around the edges of the A filter layer 11, the support layer 12 and the B filter layer 13 to prevent the A filter layer 11, the support layer 12 and the B filter layer 13 from directly contacting the outside and causing warping and separation and tearing. With the setting of the locking mechanism, the B locking member 33 is screwed to one end of the two-way bolt 32 and then placed into the through hole provided at the attachment part of the edge sealing member 21 and the filter material group. Subsequently, the A locking member 31 is screwed to the other end of the two-way bolt 32. The combined locking mechanism tightly connects the edge sealing mechanism and the filter material group together for external support and reinforcement to prevent tearing during the use of the filter material.

[0028] It should be noted that: filter gaps are provided inside both the A filter layer 11 and the B filter layer 13, and the number of filter gaps in the A filter layer 11 and the B filter layer 13 increases along the medium flow direction; when the medium flows, it passes through the A filter layer 11 and the B filter layer 13 in sequence to perform hierarchical filtration of impurities.

[0029] As Figure 3 shown, the support layer 12 includes an outer frame 121 arranged on the outside, a cross support 122 for separation is installed in the middle of the outer frame 121, and a diagonal rod group 123 with an "X-shaped" structure is installed in the four separated intervals.

[0030] Among them, the frame structure supported by the combination of the outer frame 121 and the cross support 122 adheres the filter layers on the upper and lower layers, and the separated through intervals reduce the weight of the frame structure. On the other hand, it does not hinder the normal flow of the medium, and the diagonal rod group 123 with an "X-shaped" structure internally braces the connection positions of the outer frame 121 and the cross support 122, improving the overall strength of the support layer 12 and facilitating the composite molding and filtration use of the filter layer.

[0031] In order to improve the filtration performance, further, particulate filter materials are placed in the intervals separated by the combination of the outer frame 121 and the cross support 122.

[0032] To facilitate the connection between the filter media and external devices, further, a pre-installation groove 23 is provided on the outer side of the edge-sealing member 21. The pre-installation groove 23 is connected to an external installation mechanism. The pre-installation groove 23 is convex to facilitate external cooperation.

[0033] As Figure 4 shown, the edge-sealing member 21 and the filter media group are clamped between the protruding parts of the A locking member 31 and the B locking member 33. A sealing ring sleeve (not shown in the figure) is provided in the gap where the A locking member 31, the bidirectional bolt member 32, the B locking member 33 and the filter media group are attached.

[0034] Among them, the combination of the A locking member 31, the bidirectional bolt member 32 and the B locking member 33 strengthens the A filter layer 11 and the B filter layer 13 on the support layer 12, and the setting of the sealing ring sleeve can prevent medium leakage at the connection part.

[0035] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principle of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modification examples falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
