Description

One sack cleaner in high service life

Technical field

The utility model relates to sack cleaner in a kind of high service life, particularly relates to a kind of intelligence and exchanges filter bag orientation, delays life of bag filter, extends the sack cleaner in high service life of service interval.

Background technology

Dust-precipitator is mainly used in the dusty gas cleaning treatment system of the industries such as building materials, metallurgy, chemical industry, coal, the processing of nonmetallic ore superfine powder, is the ideal equipment of Environmental-protecting dust-removing.

Mostly there is the shortcoming that power consumption is large, dust-collecting efficiency is low, operation maintenance is ordinary, maintenance cost is high in existing deduster.

The efficient long bag pulse deduster of one as disclosed in patent announcement CN 103285674, comprise housing, be located at air-purifying chamber on housing, be located at ash bucket under housing, be located at unloading valve under ash bucket, be located at filter bag in housing, be located at filter bag top injection tube, be located at air-purifying chamber one end compressed air cylinder, be located at the pulse valve on compressed air cylinder, the lift valve that is located at the air-purifying chamber other end and lift valve cylinder; The shortcoming of this structure is: filter bag is comparatively common, because air inlet is arranged at housing sidewall, level is blown into housing inner chamber, because blowing to the amount of air inlet relative direction, the effect dusty gas of baffle plate is far longer than the air inlet side ash-laden gas scale of construction, will cause like this reducing away from the life of bag filter of air inlet side, cause high maintenance rate, and little owing to loading near the filter bag of air inlet side, service life is relatively long; Both sides life-span of the filter bag is unbalanced.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of intelligence and exchanges filter bag orientation, delays life of bag filter, extends the sack cleaner in high service life of service interval.

For solving above technical problem, the technical solution of the utility model is: a kind of high service life sack cleaner, its innovative point is: comprise housing, be located at the air-purifying chamber of housing top, be located at the ash bucket of housing below, described ash bucket below is provided with unloading valve; Described housing sidewall offers air inlet and gas outlet; In described housing, be provided with filter bag, above described filter bag, be provided with injection tube, be provided with compressed air cylinder in air-purifying chamber one end, be located at the pulse valve on compressed air cylinder, be located at lift valve and the lift valve cylinder of the air-purifying chamber other end; Also comprise an intelligent reversing arrangement, described intelligent reversing arrangement comprises swivel plate, on described swivel plate, middle position is welded with the first gear, above described the first gear upside air-purifying chamber, be installed with motor and speed reducer, the second gear is installed on described speed reducer output shaft, and described the first gear and the second gear are meshed; Straight line two places crossing with swivel plate periphery of crossing the center of circle on described swivel plate are respectively provided with a sheet metal, and a proximity transducer is installed in same level with sheet metal in the inner walls of described swivel plate periphery; One control centre is installed above described air-purifying chamber.

On this basis, described air inlet is arranged at the below of described housing sidewall.

On this basis, described gas outlet is arranged at the upside of described air inlet.

On this basis, on described housing, offer maintenance window.

The beneficial effects of the utility model are: in the time using the utility model sack cleaner in high service life, after long-time use, control centre is by drive circuit drive motors, the rotation of driven rotary plate, in the time of swivel plate Rotate 180 °, the proximity transducer being installed in housing sidewall detects sheet metal, proximity transducer is converted to digital signal transfers to control centre via amplifying circuit by analog signal by signal, control centre is converted to analog signal control motor by data signal and quits work, both sides filter bag is used alternatingly, and increases the service life; In the time that filter bag control of dust is expired, the utility model pulse valve can be realized the pulse of filter bag is washed away, and realizes and collects dust; Air inlet/outlet is opened in housing one side, makes this device structure more regular; Offering of window of maintenance is convenient to internal structure to overhaul.
