The HD single machine bag filter enters the box through the inlet and is filtered by a filter bag. The dust is left on the inner surface of the filter bag, and the purified gas enters the fan through the filter bag. It is sucked in by the fan and directly discharged into the room, or it can be discharged to the outside through an exhaust pipe. As the filtration time increases, the dust adhering to the inner surface of the filter bag also increases, and the resistance of the filter bag increases accordingly, requiring dust cleaning. After the dust cleaning is completed, the dust collector works normally again. The dust collector adopts a self controlled dust cleaning mechanism for timed vibration and cleaning, or a manually controlled dust cleaning mechanism that automatically vibrates for tens of seconds after manual shutdown, to shake off the dust adhering to the inner surface of the filter bag. Dust falls into ash hoppers, drawers, or directly into production equipment. [1]

Structural Features Editing

（1） Structural characteristics of HD type single machine bag filter

The HD type single machine bag filter consists of a fan, a box, and an ash hopper. Each component is installed in a vertical frame, and the structure is extremely compact. The structural characteristics of each component are as follows.

① The fan components are selected from universal standard fans for easy maintenance and replacement, and seismic isolation facilities are used for low noise.

② The dust removal bag filter material is a cylindrical filter bag made of 208 industrial polyester twill fabric or 729 filter cloth, which has good filtration effect and long service life.

③ The dust cleaning mechanism uses an electric motor to drive the connecting rod mechanism, which causes the filter bag to shake and the dust on the inner surface of the filter bag. The control mechanism has two types: manual control and automatic control. The automatic control is that when the fan is continuously working, the dust cleaning mechanism automatically vibrates and cleans the dust at a fixed time. Manual operation means that the fan stops and the dust cleaning mechanism works automatically. After several tens of seconds, it stops automatically. The dust cleaning mechanism (motor) can also be started at any time to vibrate and clean the dust as needed. The dust cleaning time can be adjusted by the user through a time relay.

④ The ash hopper adopts two structures: drawer type and ash hopper type, making it convenient for filtering dust.
