Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, in particular to a bag dust collector skeleton structure. Background Art

[0002] Bag dust collector is a common air purification equipment, widely used in industrial, commercial and domestic environments. It filters particulate matter in the air through bag filter materials to achieve the purpose of dust removal and air purification. The working principle of this dust collector is to pass the dust-containing gas through the filter bag, and the particulate matter is retained on the surface of the filter bag, while the purified gas is discharged through the outside of the filter bag.

[0003] The frame of the bag filter is an important component of the bag filter, which is responsible for supporting the filter bag. In the existing technology, the filter bag is usually placed directly in the frame, which is composed of multiple vertical plates. The filter bag is then placed in the frame. However, when the filter bag is in use, the air or gas cannot flow evenly around the filter bag, which may cause local blockage or leakage. At the same time, the contact area between the frame and the outside of the filter bag is large, which may result in the result that the gas inside the filter bag is discharged too slowly.

[0004] Therefore, the utility model provides a bag dust collector skeleton structure. Utility Model Content

[0018] The technical effect of adopting the above further solution is: by providing the connecting piece, the first bolt and the second bolt, the pressure plate can be detachably installed on the top of the shell.

[0019] Compared with the prior art, the advantages and positive effects of the utility model are:

[0020] By using the upper stabilizing plate and the lower stabilizing plate in coordination, the stability of the top and bottom of the spiral sleeve is increased. By the action of the reinforcement rod, the bearing capacity of the spiral sleeve is further increased. By the action of the spiral sleeve, the stability of the filter bag is increased, thereby promoting a more uniform flow of air or gas around the filter bag, avoiding local blockage or leakage caused by uneven flow speed, and reducing the contact area between the skeleton and the outside of the filter bag, thereby increasing gas emissions during the use of the filter bag.
