INTRODUCTION
A large amount of dust is generated during the working process of the vibrating screen. When the dust collector starts to work, the centrifugal fan of the mine dust collector is used to form a negative pressure area at the place where the dust overflows, and the dust-containing gas is sucked into the dust collector. There are multiple filter bags in the dust collector. When the dust-containing gas passes through the filter bag, the dust is blocked and separated, and the purified gas is discharged through the fan.
When the dust on the surface of the filter bag increases and the resistance reaches a predetermined value, the pressure sensor sends an instruction signal to the electric control box, and the pulse injection system automatically controlled by pLc automatically blows the filter bag, and the dust attached to the filter bag shakes off. , directly to the belt through the sealed ash discharge pipe.
Operation
The characteristics of vibrating screen dust collector are:
1. Pulse off-line cleaning, up to 99.9% or more, dust does not produce secondary adsorption;
2. The air source pressure is only 0.2, 0.3Mpa, and the filter bag and pulse valve have a long service life;
3. To handle high temperature and high humidity gas, the filtration wind speed can reach 1.2m/min
4. The filter bag is easy to disassemble and assemble, and the sealing performance is good;
5. The electronic control plc machine is automatically controlled, easy to operate and high performance;
6. The new fms microporous thin composite filter material is suitable for various flue gas conditions and has a service life of more than 3 years;
7. Small footprint, low investment and good effect.
The hood type dust removal equipment is to control part of the dust source points in the closed hood. According to the collection of smoke and dust, the hood type dust removal equipment is used for the crushing, transportation and screening of raw materials, such as belt conveyors, vibrating screens, warehouse roofs. Wait for dust. For the vibrating screen dust collector used to deal with dust pollution in the production of mining processes, it is generally installed in the middle of the equipment. After the vibrating screen dust collector is installed, a closed device is installed above the vibrating screen, through a pipeline or other transmission equipment, and then The dust is transported to the dust collector through a huge pressure for centralized treatment to meet the environmental protection emission requirements.
