[0002] The bag filter is a dry dust filter. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of fiber fabric to filter the dust-containing gas. When the dust-containing gas enters the bag filter, the large particles and heavy dust settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, so that the gas is purified.

[0003] For example, a new type of filter bag for dust collector with announcement number CN210186638U includes a filter bag body, a dust removal frame is provided inside the filter bag body, a plurality of grooves are provided on the side wall inside the filter bag body, adsorption rods are provided in the grooves, and clamping grooves are provided on the opposite side walls in the grooves, and a limiting mechanism is provided in the clamping grooves, and the upper end of the filter bag body is fixedly connected with a bag mouth, and both sides of the bag mouth are provided with a storage cavity, and a fixing rod is provided in the storage cavity, and a fixing plate is sleeved on the fixing rod. The filter bag is tensioned by the dust removal frame to form an effective filtering interface, but because the dust removal frame structure is fixed, when the bag is loose due to long-term use, temperature changes, dust accumulation, etc., the dust removal frame cannot adjust the tension of the bag, which is easy to affect the filtering effect on the gas.

[0004] Therefore, a filter bag tensioning and slack adjusting mechanism has been developed which can adjust the tension of the bag to prevent the bag from loosening and affecting the filtering effect of the gas. Utility Model Content

[0007] Furthermore, it also includes a fixing part and an electric push rod. The fixing frame is connected to a plurality of fixing parts, and each of the fixing parts is connected to the electric push rod.

[0008] Furthermore, it also includes a movable plate and an anti-slip strip. The telescopic end of the electric push rod is connected to the movable plate, the lower side of the movable plate is in contact with the mounting frame, and the outer side of the movable plate is connected to a plurality of anti-slip strips.

[0009] Furthermore, a protective cover is also included. The upper middle part of the fixing frame is connected with the protective cover, and the protective cover is located outside the motor.

[0010] Furthermore, the protective cover is a conical structure.
