Description
Technical field
The utility model belongs to deduster technical field, is related to a kind of dedicated explosion-proof type sack cleaner of underground coal mine.
Background technique
A kind of existing sack cleaner, it is mainly made of shell, filter bag, ash bucket, anti-blow cleaning dust device.Shell
Internal two sides are dirt pocket, and upper part is equipped with upper face plate, and the upper end of filter bag is arranged on upper face plate, and the top of upper face plate is net gas
Room.Part between the dirt pocket of enclosure interior two sides, the inclined plate by being located at middle part make the part at upper and lower two Room.It is down air inlet
Room, the room and housing forward end face air inlet be connected, be above discharge chamber, the air outlet of the room and housing rear end face is connected.
Ash bucket is arranged in housing bottom.After dusty gas enters inlet plenum from air inlet when work, dusty gas is moved downward from air inlet
Room enters the change direction of motion after hopper bottom collides therewith and enters in the dirt pocket of enclosure interior two sides, and what is moved upwards contains
Dust detention in dust and gas body is purified dusty gas outside filter bag.Purified gas is out of filter bag through upper face plate
It is discharged into air-purifying chamber, then from discharge chamber by exhaust blower from air outlet.After the running resistance of deduster increases to certain value, instead
The pulse valve of blowing deashing device is opened, and back-blowing enters in filter bag, and the filter bag shriveled originally expands deformation, removes filter bag
Outer surface attachment dust, clearly under dust fall into ash bucket.Deduster after a period of work, always has one on ash bucket inner surface
The thicker dust of layer.
In industrial enterprise, in the technical process such as pulverized coal preparation, metal ball blast, smelting non-ferrous metal in can generate and raise
Dirt had not only polluted operating environment but also had polluted atmospheric environment.For many years, industry uses a variety of dedusters to administer, and has achieved
Effect, but due to many, occurs that occupation area of equipment is big, life-span of the filter bag is short, and equipment resistance is high, concentration of emission height etc.
The problem of influencing efficiency of dust collection, however existing some high-effective dust-removing equipment lead to gas since internal structure arrangement is unreasonable
Since the expansion of air pressure easily causes equipment explosion when flue dust etc. enters deduster.
