Dust collector structure of mine crusher:

1. Upper box: Contains the dust collector cover, rotary cover removal equipment, cleaning room, bag changing hole, investigation hole, and air outlet after purification.

2. Medium box: It includes flower plate, filter bag, filter bag structure, filter bag guide, filter chamber tube, dust-containing gas inlet and inlet.

3. Lower box: Contains positioning support frame, ash bucket, star-shaped ash discharge valve, and support.

4. Anti-blowing and dust-cleaning tissue: including spiral arms, mouthpieces, looped blow-back tissues, circulating air ducts, anti-blow tubes, anti-blowers, and spiral arm deceleration tissues.

The mine crusher dust collector is not restricted by the gas source conditions of the use occasion, with few wearing parts, convenient protection and reliable operation. Overcome the problem of compressed air pulse dust removal, the interval of the anti-blowing effect is large, long cloth bags can be used to make full use of space and occupy a small area.

The working principle of the mine dust collector is to enter the dust-containing gas tangentially into the upper space of the filter room. Under the effect of centrifugal force of large particles and agglomerated dust particles, the ash bucket is rotated down the cylinder wall, and small particles are dispersed in the empty space between the bags of the filter room and then blocked. Purified air passes through the wall of the bag and collects in the cleaning room through the filter bag guide on the flower plate. It is sucked in by the ventilator and discharged into the atmosphere. With the progress of the filtering conditions, dust is attached to the surface of the dust removal bag, and the resistance of the dust removal bag is gradually added. When the upper limit of the resistance of the anti-air blower is reached, the differential pressure transmitter connected to the front and rear interfaces of the dust collector sends a signal to initiate the reaction. Blow to organize the job.

Purification of dust only needs to be performed by a bag filter. The selection of the dust collector directly affects the capture effect of the dust removal system, the power consumption of the dust removal, and whether the entire system can be stably and reliably operated for a long time. The way of the dust collector is complicated, each has its advantages and disadvantages. The key lies in how to learn from each other. Adapt to the system technology and dust composition to achieve good results. As for material transportation, a bag filter is more suitable. Its effect of removing fine dust is remarkable, and the emission concentration can be controlled below 20mg / Nm3.

Generally speaking, the dust removal efficiency of different types of dust collectors will change under different operating conditions. When selecting mine dust collectors, comprehensive consideration should be given to relevant parameters of factories and mining enterprises, and reasonable dust collectors should be determined according to the prescribed emission standards. To achieve the desired dust removal effect.

1. When determining the dust collector according to the required dust removal efficiency, the stability of the processing air volume should be considered. For example, the efficiency of the cyclone dust collector will increase with the increase of the processing air volume, while the efficiency of the electrostatic dust collector will decrease with the increase of the wind speed of the electric field.

2. Gas and dust properties and particle size distribution are of great significance to the choice of dust collector. To select a suitable filter material according to the characteristics of the dust to be purified, pay attention to the wear of the dust on the inner wall of the cyclone dust. The corrosive gas and dust can cause premature damage to the dust collector in the wet dust collector, so It is very important to choose the type of dust collector according to the nature of the dust. For this kind of gas, a stainless steel dust collector can be selected. This type of dust collector has a good effect on anticorrosion.

3. When a bag type dust collector is used to process a gas with a high dust concentration, a low-resistance pre-stage dust removal device should be provided, which can improve the filtering wind speed of the bag type dust collector.

4. Consider recycling of collected dust. For example, dust such as cement should be included in the recycling process system.

5. According to the specific conditions of factories and mines, the selection of technically feasible and economical dust collectors, such as energy, equipment investment, steel consumption, size of the floor area and technical requirements, are all constraints in selecting mine dust collectors.
