Furthermore, the filter bag of the bag-type dust collector adopts a film-coated terylene needling filter felt.
Further, a heater is arranged outside the box body of the bag-type dust collector.
Adopt above-mentioned technical scheme to have following beneficial effect:
the dust absorption screening system is simple in structure, dust in the coal chute of the screening system is absorbed by the first dust absorption cover and the second dust absorption cover and enters the bag-type dust remover, and the absorbed coal dust falls onto the transmission belt of the belt conveyor through the blanking pipe through the bag-type dust remover, so that the passing area is increased, the dust concentration in the screening chamber is less than 50mg/m3, the environmental pollution is reduced, and the recycling of the coal dust is realized.
The box of the bag-type dust collector is externally provided with a heater, and when the humidity of the coal dust is higher, the coal dust in the bag-type dust collector is heated by the heater, so that the coal dust is dried and falls onto a transmission belt of a belt conveyor through a blanking pipe.
The filter bag of the bag-type dust collector adopts a film-coated terylene needle-punched filter felt, the dust collection efficiency is high, and the ash removal is easy
The following description is further described in conjunction with the accompanying drawings and the detailed description.
