Generally, the dust removing method is divided into pulse type dust removing filter bags, vibration type dust removing cloth bags, back blowing type dust removing cloth bags and the like according to different dust removing modes. In pulse and air box type pulse dust collector, dust is attached to the outer surface of the filter bag. When the dust-containing gas passes through the dust remover, the dust is trapped on the outer surface of the filter bag, and the clean gas enters the interior of the filter bag through the filter material.
The bag-type dust collector has the defects that the filter bag needs to be replaced, some filter bags need to be replaced in a short time of several months, the traditional bag-type dust collector adopts a round bag, the void ratio among the round bags is large, and particularly for a large-scale dust collector, the whole appearance is large, the operation cost and the maintenance workload are increased, in addition, the whole blowing system is complicated, the equipment investment is large, the maintenance and the occupied area are large, and the inconvenience is brought to users.
The utility model has the following contents:
the utility model aims at providing a bag type dust collector to the problem that above-mentioned exists, simple structure, it is convenient to change the sack, and equipment investment is little, and area is little.
The above purpose is realized by the following technical scheme:
the utility model provides a cloth bag type dust collector, includes the box, box one side be provided with the air intake, the opposite side of box is provided with the air outlet, the box the inside is provided with a set of top guide roll and lower guide roll respectively from top to bottom at the interval, the air intake of box the inside and the both sides of air outlet are provided with motorized pulley respectively, the filter bag is walked around through upper and lower U type end to end the top guide roll and lower guide roll and two respectively fixed connection in both sides motorized pulley on, every the upper portion of going up the guide roll and every the lower part of guide roll is provided with the brush respectively down, every interval on the filter bag two times distance department between top guide roll and the lower guide roll is provided with the ash falling hole.
The bottom of the box body of the cloth bag type dust collector is provided with a dust collecting hopper.
The filter bag of the cloth bag type dust collector is fixedly connected with the electric roller by a pressure spring clamp.
In the cloth bag type dust collector, each electric roller is respectively connected with a driving motor, and the driving motors on two sides are synchronously controlled by the same variable frequency controller.
The bag type dust collector is characterized in that an induced draft fan is arranged at the air outlet.
The filter bag of the cloth bag type dust collector adopts an integral filter bag.
Has the advantages that:
the utility model discloses a guide roll that sets up from top to bottom arranges the filter bag layering, the filter bag adopts flat filter bag or individual layer filter cloth can realize, for drum type filter bag, the equipment space has been saved, in addition the brush deashing through upper and lower setting, motorized pulley through both sides drives the filter bag and removes, the brush deashing to it, the brush deashing of lower part directly falls into the ash collecting bucket, after the brush deashing on upper portion falls down, wait the filter bag rotate to fall down from falling down in the ash hole when being located under, overall structure has got rid of traditional jetting system numerous and diverse's pipeline and valve etc. simple structure, and the in-process of changing only needs to fix the head and the tail of a whole filter bag on the motorized pulley of both sides, it is convenient to change the sack, the equipment investment is little, area is little.
The filter bag with motorized pulley between adopt the mode of pressure spring clamping fixed connection to connect, it is more convenient to dismantle the change filter bag.
