Description
[technical field]
The utility model relates to a kind of dust arrester, is a kind of single blower fan negative pressure sack cleaner with anti-blow cleaning dust function specifically.
[background technology]
The engine house that some often produce a large amount of dust generally all is equipped with sack cleaner, in order to purify air, avoids harmful dust to damage the healthy of operator.Present sack cleaner is to allow the air of dust through a plurality of cloth bag filtrations, with dust every outside cloth bag, only allow be not with or the air of a small amount of fine dusts by cloth bag, deliver in operating room or the atmosphere by air exhauster at last.Because cloth bag can accumulate dust gradually in the process that intercepts dust, block the pore on the cloth bag gradually, not only will increase the power consumption of blower fan, also can reduce dust removing effects, also can lose dedusting function when serious.Therefore, after work a period of time, must shut down cloth bag is carried out the labor cleaning, a large amount of dust that cloth bag is being attached outward are by beaing or dither method removes.Like this, not only labour intensity is big, and also time-consuming taking a lot of work delayed production.
[summary of the invention]
For overcoming the above-mentioned defective of existing sack cleaner, the utility model provides a kind of single blower fan negative pressure sack cleaner with anti-blow cleaning dust function, after work a period of time, when cloth bag is stained with dust outward, as long as move two switches, blower fan will be dried by automatic reverse, and the dust that cloth bag is being attached outward blows off.
For solving its technical problem, the technical solution adopted in the utility model is: design and comprise casing, a plurality of cloth bags in the casing, dust air inlet on the box body wall, dust hopper, single blower fan blowback wind negative pressure bag-type dust collector of dust mouth and blower fan, its feature is: the negative pressure chamber that is provided with a sealing on the top of casing, be fixed with the gas outlet of a plurality of cloth bags on the base plate of this negative pressure chamber, each cloth bag is suspended in the casing, skeleton all is installed in the cloth bag, be provided with two airducts on the top board of closed chamber, the end in the triple valve on one of them airduct and the fan wind inleting tube is connected, and the end in the triple valve on another airduct and the blower fan discharge pipe is connected, all the other two ends of described two triple valves are an end and communicate with atmosphere, and the other end communicates with the blast pipe or the discharge pipe of blower fan; Be provided with a two-way switch in the valve body of described triple valve, this switch realizes opening/closing conversion by manual or electronic controller.
Be provided with tapered dust hopper in the bottom of described casing, the angle of tapered dust hopper is 55 °～60 °, relay valve is installed in the bottom of dust hopper, when the weight of dust is increased to certain value in the dust hopper, overcome the pressure of counterweight, force the relay valve valve open, dust glides in the dust hopper, after dust pressure reduced, counterweight weight forced the servo valve closing.
Compare with existing sack cleaner; the utility model has following beneficial effect: 1, the utility model is in work; can oppositely dry; can dispose the dust that cloth bag is attaching fast outward; avoided need shutting down the defective of manually clearing up cloth bag, therefore, it has not only alleviated working strength of workers in the past; also reduce downtime, helped improving efficiency of dust collection.The frequent blowback wind of energy to dispose the outer dust of cloth bag, makes the aeration status of cloth bag often in shape during 2, owing to the utility model work, helps alleviating the load of blower fan, can save a large amount of electric energy.According on probation, the utility model is used for filter area 17m
2, only need 1.5 kilowatts blower fan, filter area 20m
2, only need 2.2 kilowatts motor.Economize on electricity 30～40% on year-on-year basis.3, the utility model is only used a Daepori ventilation blower, avoided need using high pressure positive blower, so cost is low in the past, and is easy to maintenance, easy to utilize.
[description of drawings]
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1, triple valve, 2, blast pipe, 3, blower fan, 4, discharge pipe, 5, triple valve, 6, sealing negative pressure chamber, 7, cloth bag, 8, skeleton, 9, casing, 10, dust hopper, 11, counterweight, 12, relay valve, 13, the servo valve, 14, the dust air inlet, 15, baffle plate.
[specific embodiment]
With reference to accompanying drawing: the utility model comprises: casing 9, a plurality of cloth bags 7, dust air inlet 15, air intake baffle plate 13, relay valve 12 and blower fan 3, be provided with the negative pressure chamber 6 of a sealing on the top of casing, be fixed with the gas outlet of a plurality of cloth bags 7 on the base plate of this negative pressure chamber, each cloth bag is suspended in the casing, the skeleton made from steel wire 8 all is installed in the cloth bag, on the top board of negative pressure chamber, be provided with two airducts, one of them airduct with in establish two-way switch triple valve 1 one ends be connected, the two ends in addition of this triple valve, one end communicates with atmosphere, the other end is connected with the blast pipe 2 of blower fan 3, another airduct is connected with an end of the triple valve 5 that two-way switch is arranged, the two ends in addition of this triple valve 5, an end communicates with atmosphere, and an end is connected with the discharge pipe 4 of blower fan 3.
