Description
Technical field
The present invention is a kind of sack cleaner, belongs to environmental protection machinery equipment technical field.
Background technology
Some produce the workshop of a large amount of dust, sack cleaner are equipped with, for purifying air, it is to avoid harmful dust is damaged
Workman's is healthy；The current small-sized few reverse gas cleaning functions of sack cleaner, medium-sized and large-scale sack cleaner is all
Reverse gas cleaning system is designed with, has and deashing is carried out using back blowing machine, is had using air compressor jetting deashing etc., except gathering dust
Outside blower fan, installation reverse gas cleaning blower fan or compressor are additionally needed, sack cleaner operation needs two air blowers to work simultaneously,
Power consumption is big, and equipment is more complicated, repairs also pretty troublesome etc..
The content of the invention
In order to solve the above problems, present invention design is a kind of only to be run with an air blower, real by a set of change-over switch
The negative pressure bag-type dust collector that existing dedusting and deashing are completely combined.
In order to solve the problems, such as above-mentioned branch art, a kind of sack cleaner, including:Air hose, air intake threeway valve block, air blower
Aspiration channel, air blower, air blower discharge pipe, air-out threeway valve block, discharge pipe, deduster exhaust column, anti-blowpipe, ipper air chamber, cloth
Bag inner frame, dust-removal cloth-bag, outer case of dust remover, dirt airduct, lower air chamber, series connection relay valve, blowback branch pipe.
It is characterized in that:Ipper air chamber and lower air chamber are provided with outer case of dust remover, ipper air chamber is negative pressure chamber, is exported as deduster
Exhaust column simultaneously connects with air intake threeway valve block room blast pipe, and air intake threeway valve block is changed in air intake threeway valve block room, works as dedusting
When device works：Air intake threeway valve block closes air hose, and fan induced draught pipe is opened；Air-out threeway valve block closes anti-blowpipe, opens
Discharge pipe.
It is provided with lower air chamber in outer case of dust remover inside many dust-removal cloth-bags, dust-removal cloth-bag and cloth bag in-seam is installed
Frame, the dust-removal cloth-bag section mouthful suitable for reading with ipper air chamber downwards connects, and lower air chamber is provided with the air inlet of dirt airduct, dirt airduct and dust-laden
Workshop is connected in room.
The lower mouth of lower air chamber's vertebra shape bucket is provided with double relay valves of series connection, for automatic gas-locking ash discharge.
When deduster is used for high-temperature hot-air dedusting, cloth bag material should use the glass fibre cloth of superelevation heatproof, heatproof
It should be greater than 200 DEG C of degree；Cloth bag inner frame is designed as spring steel wire and rolled to form.
At normal temperatures during dedusting, inner frame is designed as plastic grid inner frame.
Dusty gas connects because of the suction of air blower, the outlet of air blower with the blast pipe of air-out threeway valve block room, threeway
Two discharge pipes of valve block room, one of outlet between ipper air chamber by anti-blowpipe with being connected, another discharge pipe and big gas phase
Connection, threeway valve block now is in the state for closing anti-blowpipe, and discharge pipe is opened.
Reverse gas cleaning, which is also named, flashes deashing：Air-out threeway valve block now opens the air hose for entering air, and blower fan is inhaled
Airduct is closed, while being opened anti-blowpipe by air-out threeway valve block, closes discharge pipe；Negative pressure chamber's fast transition is plemum, drum
The pressure wind of blower fan pass through air blower discharge pipe, into anti-blowpipe after every dust-removal cloth-bag inner chamber is blowed to by blowback branch pipe again, this
When dust-removal cloth-bag drum is big rapidly, the dirt ash adsorbed in dust-removal cloth-bag outer surface is blown off, then dust removal state is rapidly returned back to again.
The outlet air end of anti-blowpipe is connected with blowback branch pipe much thinner, and blowback branch pipe puts in every dust-removal cloth-bag outlet
It is interior, 10-20mm depth is inserted inwards.
The angle of vertebra shape bucket is 60-62 degree.
The air blower of 10000 cubic metres of disposal ability per hour, airduct basal area should be greater than 0.4 square metre.
For favourable reverse gas cleaning, per hour 10000 cubic metres disposal ability when dust-removal cloth-bag answer intended diameter to exist
Between 300-400mm.
The dust-removal cloth-bag gross area is no less than 300-500 square metres, and the dust-removal cloth-bag gross area is determined by the grey moisture content of dirt.
The deashing blowback time is designed as 6-10 seconds, if dirt ash water content is higher, the blowback time wants proper extension, instead
It, the blowback time can shorten.
Blowback overlong time can be influenceed to gather dust, and the blowback time is too short, and ash-removal effect can be reduced again.
When dusty gas temperature is higher, cloth bag material should use the glass fibre cloth of superelevation heatproof, and heatproof should be greater than 200
DEG C degree.
A kind of sack cleaner that the present invention is set has following progress compared with general sack cleaner.
The present invention can reduce a reverse gas cleaning air blower or pressure fan using conversion wind direction reverse gas cleaning.
Reverse gas cleaning control is simple, and operation is flexible, and ash-removal effect is preferable.
The present invention can reduce equipment, simplify design, reduce investment.
Automation dedusting can be achieved using microcomputer control.
Equipment making is simple, is adapted to large, medium and small type sack cleaner design and installation and uses.
