[0006] In order to improve the convenience and efficiency of the assembly of the filter box chamber body, the top plate, the left and right side plates and the front and rear side plates are all assembled by a plurality of rock wool plug-in plates.

[0007] In order to realize the heat preservation function of the whole filter box chamber body, the rock wool plug-in plate is a heat preservation material, and a heat preservation layer, a skeleton and heat preservation nails do not need to be designed additionally.

[0008] In order to better protect the corner joints, the joints of the top plate, the left and right side plates and the front and rear side plates are provided with corner cover plates.

[0009] As preferred, the corner angle plate section is L-shaped, and frame connecting parts are extended inwardly from two side edges, and other structures of the corner angle plate can also be designed according to actual conditions.

[0010] In order to improve the rigidity of the whole filter box body, an internal frame is further included, which supports an internal part arranged inside the box body and intermittently spot-welded to the inner surface of the box body.

[0011] Further, the internal frame includes a plurality of vertical steel pipes arranged in a vertical direction and a plurality of horizontal steel pipes arranged in a horizontal direction, and the corners of the box body are provided with the vertical steel pipes or the horizontal steel pipes.

[0012] In order to further improve the assembly convenience, the base is of an integral structure and is integrally formed.

[0013] In order to prevent condensate water from leaking to the bottom and to timely discharge the condensate water, the base is of a waterproof structure and is connected with a drain pipe.

[0014] The application has the following beneficial effects: the novel filter box body structure applied to VOC waste gas treatment of a coating line is characterized in that the box body is assembled by rock wool plug-in plates with heat preservation performance, which replaces the stainless steel bent inner and outer plates with a heat preservation layer structure in the prior art, greatly improves the assembly convenience of the filter box body, thereby improving the efficiency, simplifying the structure and improving the material utilization rate; the internal frame is spot-welded inside the box body assembled by the rock wool plug-in plates, thereby improving the rigidity and reliability of the whole box structure; in addition, the novel filter box body structure applied to VOC waste gas treatment of a coating line is compact in structure, good in sealing performance and waterproof performance, and high in economy.
