Such a structure can avoid the cage from blocking the airflow excessively.
In the bag-type dust collector, the filter bag is coated on the second support ring and the first support ring, and the port of the filter bag is connected to the first support ring.
In the bag-type dust collector, the inner side of the support ring is provided with the X-shaped support rod, the end part of the support rod is fixedly connected with the inner side of the support ring, and the upper end of the connecting rod is fixedly connected with the X-shaped intersection of the support rod.
In the bag-type dust collector, the inner sides of the two support rings are provided with X-shaped support rods, the end parts of the support rods are fixedly connected with the inner sides of the two support rings, and the lower ends of the connecting rods are fixedly connected with X-shaped cross positions of the support rods.
The bracing piece is X shape and tip fixed connection at the support ring inner wall, and such structure can effectively improve support ring intensity, but also can avoid blockking to the air current as far as possible.
In the bag-type dust collector, the filter bag is made of woven filter cloth or non-woven felt.
The filter bag has the advantages of wide application range, long service life and high dust removal efficiency, can capture dust which is difficult to recover by electric dust, can be used for collecting organic nitrated compounds, sulfides and the like to a certain extent, and has higher safety when collecting dust-containing gas containing explosion risks or sparks.
In the bag-type dust collector, the clamping part is connected with the upper end of the cage frame into a whole and is buckled on the inner wall of the ash hopper.
Through the setting of joint portion, can be with the effectual ash bucket inner wall that is fixed in of filter bag, prevent to produce the shake at the during operation filter bag.
Compared with the prior art, dirty gas deposits because of the effect of gravity in this sack cleaner, fall into the ash bucket, the gas that contains finer dust is when passing through the filter bag, the dust is detained, the dust is attached to the surface of filter bag repeatedly, make gas obtain purifying, the suitability is strong can eliminate slight dirt particle, the dust particle size scope that can catch is big, in addition the filter bag can appear wearing and tearing after using a period of time, burn out, corrode etc., the one deck dust also can pile up on the surface of filter bag, change filter bag that can convenient and fast, can effectual clearance filter bag, the life of extension filter bag, moreover, the steam generator is simple in structure, high adaptability, stability is reliable, can catch the dust of different properties.
