Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

Referring to fig. 1, the bag type air filter with adjustable filtering area of the present invention includes a rectangular frame 1 and a detachable filter cloth 2 connected to the frame. An inserting edge 11 is arranged on the outer side surface of any edge of the frame 1, a connecting cavity 12 is correspondingly arranged on the outer side surface of the edge of the frame 1 opposite to the edge on which the inserting edge 11 is arranged, and the inserting edge 11 can be inserted into the connecting cavity 12. Be located its opening part and be provided with limiting plate 3 in connecting cavity 12, still be provided with many springs 5 with the lower fixed surface of limiting plate 3 and pass two guide posts 6 of limiting plate 3 in connecting cavity 12, guide post 6 is located two tip near limiting plate 3, guide post 6 with be connected the upper and lower inside wall fixed connection of cavity 12, limiting plate 3 can reciprocate along guide post 6, the lower extreme of spring 5 and the lower inside wall fixed connection who is connected cavity 12, the lower fixed surface of upper end and limiting plate 3 is connected. Therefore, when two different bag air filters are to be connected, the stopper plate 3 is pressed downward, the insertion edge 11 of one bag air filter is inserted into the connection cavity 12 of the bag air filter, and then the insertion edge 11 is fixed in the connection cavity 12 by the urging force of the spring 5. Thus, it is possible to connect the frames 1 of a plurality of different bag air filters and to achieve an adjustment of the filter area in the longitudinal direction (see fig. 2). It is clear that it is also possible to provide the bag air filter with a plug-in edge 11 at both adjacent edges and correspondingly to provide the connecting chamber 12 at the edge opposite to the edge at which the plug-in edge 11 is provided, whereby an adjustment of the filter area in the length and width direction of the filter can be achieved.

Referring to fig. 3, the end of the insertion edge 11 is provided with a connection edge 111 capable of being mutually clamped with the limiting plate 3. After the inserting edge 11 is inserted into the connecting cavity 12, the connecting edge 111 can be mutually clamped with the limiting plate 3, so that the inserting edge 11 is ensured not to slide out of the connecting cavity 12, and the firm connection of two adjacent bag type air filters is ensured. The distance between the mutually approaching surface of the stopper plate 3 and the insertion rim 11 and the connection rim 111 gradually increases in a direction from the opening of the connection cavity 12 toward the bottom of the connection cavity 12. Therefore, under the guidance of the slope structure of the limit plate 3, the connecting edge 111 can be conveniently pushed into the connecting cavity 12, and can be firmly clamped with the limit plate 3 in the connecting cavity 12.

Referring to fig. 4, the utility model discloses a bag type air filter has seted up a filter cloth spacing groove 4 along the length direction of edge respectively on each edge of frame 1, is provided with a fixed layering 7 respectively corresponding to every filter cloth spacing groove 4, and fixed layering 7 is corresponding respectively to articulate in a tip of filter cloth spacing groove 4. One end of each filter cloth limiting groove 4 is fixedly provided with a hinge shaft 41 which is perpendicular to the opening direction of the filter cloth limiting groove 4, and the fixing pressing strip 7 which is arranged corresponding to each filter cloth limiting groove 4 correspondingly penetrates through one hinge shaft 41, so that the fixing pressing strip 7 can swing along the hinge shaft 41 and can rapidly realize the disassembly and assembly of the filter cloth 2.

As shown in fig. 5, the width of the fixing pressing bar 7 of the present invention gradually decreases toward the distance from the surface close to the filter cloth limiting groove 4, and the width of the bottom of the filter cloth limiting groove 4 is not less than the width of the surface close to the filter cloth limiting groove 4 of the fixing pressing bar 7. Therefore, the fixing pressing strip 7 can be firmly clamped with the filter cloth limiting groove 4, so that the filter cloth is fixed, when the bag-type air filter reaches a filtering saturation value, the fixing pressing strip 7 can be quickly taken down from the filter cloth limiting groove 4, and the filter cloth 2 is convenient to clean or replace. As a preferred embodiment of the present invention, the surface of the fixing pressing strip 7 near one side of the filter cloth limiting groove 4 can be further provided with a rubber layer, so that the fixing pressing strip 7 can be better clamped in the filter cloth limiting groove 4.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered in the protection scope of the present invention.
