Description

Technical Field

[0001] The utility model relates to the technical field of air filters, in particular to a modular air filter structure. Background Art

[0002] Air filter is a device that captures dust from gas-solid two-phase flow and purifies the gas through the action of porous filter materials. It sends the low-dust air into the room after purification to ensure the process requirements of the clean room and the air cleanliness in the general air-conditioned room.

[0003] The air filter is mainly composed of two parts: an outer frame and filter paper. Currently, the filter paper is fixed to the outer frame by common fixing methods such as gluing, binding with ropes, hot pressing or riveting. Among them, the air filter fixed by gluing is prone to odorous gas volatilization during processing and use, which cannot meet the current environmentally friendly processing and use requirements. The fixing methods such as gluing, binding with ropes, hot pressing or riveting require operators to operate the equipment, which increases the processing difficulty and manufacturing cost of the air filter and does not meet the current green manufacturing processing requirements.

[0004] In view of this, it is particularly important to design and manufacture an air filter structure that has low processing difficulty, controllable manufacturing cost, and meets green environmental protection requirements. Utility Model Content

[0007] A modular air filter structure comprises an outer frame and filter paper arranged inside the outer frame, wherein a mold assembly mechanism for limiting and fixing the filter paper assembly inside the outer frame is arranged between the outer frame and the filter paper.

[0008] As a further description of the above technical solution:

[0009] The molding mechanism includes side fasteners symmetrically fastened on the left and right ends of the filter paper and fitted with the inner wall of the outer frame, a plurality of supporting rods equidistantly fixed on the inner sides of the side fasteners and fastened with the folded parts of the filter paper, a one-way locking block symmetrically fixed on the outer sides of the vertical ends of the side fasteners, and a one-way locking groove opened on the left and right ends of the outer frame and corresponding to the one-way locking block.

[0010] As a further description of the above technical solution:

[0011] The molding mechanism also includes T-shaped hollow cannulas symmetrically fixed on the front and rear ends of the filter paper, transverse slots opened on the two horizontal ends of the side fasteners and used for the transverse insertion of the T-shaped hollow cannulas, and lower slots opened on the front and rear ends of the outer frame and used for the vertical insertion of the T-shaped hollow cannulas.

[0012] As a further description of the above technical solution:

[0013] The inner side of the side fastener is fixedly connected with a plurality of sealing buckle strips which are buckled with the folded parts of the side edges of the filter paper.

[0014] As a further description of the above technical solution:

[0015] The outer sides of the two horizontal ends of the side fasteners are located above the T-shaped hollow inserting pipe and are fixedly connected with lower inserting blocks corresponding to the lower slots.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0017] In the utility model, the original air filter structure is scientifically and rationally improved, and side fasteners are added between the outer frame and the filter paper. The side fasteners can be stably wrapped on the outside of the filter paper through supporting rods, T-shaped hollow tubes and transverse slots.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 The utility model provides a technical solution: a modular air filter structure, including an outer frame 1 and a filter paper 2 arranged on the inner side of the outer frame 1, and a molding mechanism is arranged between the outer frame 1 and the filter paper 2 for combining and limiting the filter paper 2 and fixing it on the inner side of the outer frame 1.

[0025] The molding mechanism includes side fasteners 3 symmetrically buckled on the left and right ends of the filter paper 2 and fitted with the inner wall of the outer frame 1, a plurality of support rods 301 equidistantly fixed on the inner side of the side fasteners 3 and buckled with the folded part of the filter paper 2, a one-way locking block 303 symmetrically fixed on the outer side of the vertical end of the side fastener 3, and a one-way locking groove 102 opened on the left and right ends of the outer frame 1 and corresponding to the one-way locking block 303. After the one-way locking block 303 is inserted into the one-way locking groove 102, the side fastener 3 will be stably locked in the outer frame 1.

[0026] At the same time, the molding mechanism also includes a T-shaped hollow cannula 201 symmetrically fixed on the front and rear ends of the filter paper 2, a transverse slot 305 opened on the two horizontal ends of the side fastener 3 and used for the transverse insertion of the T-shaped hollow cannula 201, and a lower slot 101 opened on the front and rear ends of the outer frame 1 and used for the vertical insertion of the T-shaped hollow cannula 201. When the T-shaped hollow cannula 201 slides into the transverse slot 305, the filter paper 2 and the horizontal ends of the side fastener 3 can be actively fixed, thereby improving the stability and air tightness of the connection between the filter paper 2 and the side fastener 3 after assembly. At the same time, the opening of the lower slot 101 can hide and fix the end of the T-shaped hollow cannula 201 in the outer frame 1.

[0027] Specifically, Figure 1-3 As shown, the inner side of the side fastener 3 is fixedly connected with a plurality of sealing strips 302 which are engaged with the folded parts of the side edges of the filter paper 2. The provision of the sealing strips 302 enables the side ends of the filter paper 2 to be stably engaged with the side fastener 3, thereby improving the air tightness between the filter paper 2 and the side fastener 3 after assembly and the stability of the structural connection.

[0028] Specifically, Figure 1-3As shown, the outer sides of the two horizontal ends of the side fasteners 3 are located above the T-shaped hollow insert 201 and are fixedly connected with a lower insert block 304 corresponding to the lower slot 101. The setting of the lower insert block 304 can limit and fix the side fasteners 3 on the inner side of the outer frame 1, further improving the structural connection and load-bearing stability of the combination of the side fasteners 3 and the outer frame 1.

[0029] Working principle: When using, first, pick up the filter paper 2, and insert the support rod 301 on the inner side of the side fastener 3 into the folded part of the filter paper 2, and then squeeze the end of the filter paper 2 into the sealing buckle strip 302 of the side fastener 3. At the same time, the T-shaped hollow cannula 201 on the filter paper 2 will slide into the horizontal slot 305 of the side fastener 3, and the filter paper 2 can be stably unfolded and fixed between the two side fasteners 3. Secondly, the two closed side fasteners The one-way locking block 303 on the component 3 slides downward into the one-way locking groove 102 of the outer frame 1. When the one-way locking block 303 is elastically locked into the one-way locking groove 102, the two side fasteners 3 will be hidden and fixed in the outer frame 1. At the same time, the lower insert block 304 on the side fastener 3 and the T-shaped hollow insert tube 201 on the filter paper 2 will also slide into the lower slot 101 of the outer frame 1, thus completing the comprehensive limiting and fixing operation between the filter paper 2 and the outer frame 1.
