HD type standalone dust collector

The HD type single machine dust collector is a small mechanical vibrating bag dust collector, mainly used for dust removal on the top, bottom, belt conveyor, and local dust sources of the warehouse. The dust coming down from the unit can be directly discharged into the warehouse or directly fall onto the belt. The dusty gas enters from the lower part of the machine body. After filtering through the filter bag, the clean air is discharged by the induced draft fan. After the equipment works for a period of time, the dust on the filter bag gradually increases, causing the resistance of the filter bag to rise. It needs to be eliminated. After elimination, the unit can resume normal operation.

The HD type single machine dust collector has six specifications, divided into three types: A, B, and C. Type A does not have a dust door, type B does not have drawers, and type C neither has a dust door nor drawers; The lower addition is directly connected to the dust collector at the top of the warehouse, material bin, belt conveyor, etc. according to requirements for on-site dust removal, and the dust is directly recovered.

The HD type single machine dust collector consists of three components: a fan, a box, and an ash hopper. Each component is installed in a vertical frame and has a compact structure. 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 filter bag is a cylindrical filter bag made of polyester filter cloth, which has good filtering effect and long service life.

3. The dust cleaning mechanism is a method of using an electric motor to drive a connecting rod mechanism, causing the filter bag to shake and remove dust from the inner surface of the filter bag. Its control device is divided into two sides and three types of self-control. The self-control is that when the fan is continuously working, the dust cleaning mechanism automatically vibrates and cleans the dust at a fixed time. Manual control refers to the automatic operation of the dust cleaning mechanism after the fan is stopped, and it will automatically stop after tens of seconds. The dust cleaning mechanism (motor) can also be started at any time as needed to vibrate and clean the dust. The dust cleaning time can be adjusted by the user by cutting off the power supply.

4. The ash hopper adopts two structures: drawer type and ash hopper type, which are convenient for dust collection.

Working principle of HD type single machine dust collector:

The dusty gas enters the box through the inlet of the dust collector and is filtered by the dust removal filter bag. The dust is left on the inner surface of the dust removal filter bag. The purified gas enters the fan through the filter bag and is directly sucked into the room by the fan. It can also be discharged to the outside through an exhaust pipe. As the filtration time increases, the dust adhering to the inner surface of the dust removal filter bag also increases, and the resistance of the dust removal filter bag increases accordingly, requiring dust cleaning. After the dust cleaning is completed, the single machine bag filter can work normally again.

The HD type single machine 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 dust removal filter bag. Dust falls into ash hoppers, drawers, or directly into dust producing equipment.

Three types of ash discharge methods for HD type single machine dust collector:

1. The bottom of the HD type single machine dust collector is equipped with an ash hopper to collect dust. The dust falls into the ash hopper and is regularly cleaned by the staff. It is mainly suitable for gas purification in ventilation openings with low concentration.

2. The bottom of the HD type single machine dust collector is equipped with a drawer for collecting dust, which can be directly dropped into the drawer and pulled out for easy dust discharge. Generally applicable to dust points at the bottom of warehouses and conveying equipment.

3. The bottom of the HD type single machine dust collector is open and does not have ash hoppers or drawers. Dust is directly recovered and purified and collected in coal bunkers, silos, and warehouses.
