Description

Coal separation deduster
Technical field
A kind of coal separation deduster is the utility model is related to, in coal field.
Background technology
With novel dry cleaning unit constantly development and Environmental protection requirement continuous improvement, Its equipment shows exclusive superiority, is widely applied in screening technology flow.But most of dry coal separators are not matched somebody with somebody Cleaner is put, even if there are dust removing effects nor too preferable.Directly contributing most dry type coal preparation plants, all there is coal dust Big phenomenon, the physical and mental health of employee is had a strong impact on, pollute surrounding environment, brought much to plant area's production and the life of people It is unfavorable.
The purge mode used by the sack cleaner is overall reverse gas cleaning, and an only operating room.Both bag is worked as Yin blower fans are in running order in the case of formula deduster is in dust removal state) when needing deashing, will be in same operating room Two kinds of opposite gases will occur, that is absorbing quantity is formed with blowback air quantity and cancelled out each other;Therefore in continuous fortune for a long time In row, often generation deashing is not thorough, or even blocks phenomenon;The filter area of the deduster is less than normal, continuous operation A bit of time, dust settling pocket are all stifled real, to increase air inducing resistance, will cause the wretched insufficiency of air quantity.
Using swinging entirety deashing, its deashing intensity is poor, while neighboring area has a deashing dead band, in Ji Gai areas Coal dust on dust settling pocket timely and effectively can not be removed thoroughly, and the phenomenon that dust stratification increases occurs in work a period of time dust settling pocket, The resistance of absorbing quantity can equally be increased, while also thoroughly block the dust settling pocket for causing the area;Outside in addition, the coal master of my company It is sticky bigger after its chance water based on powder coal, as effectively removed the coal dust on dust settling pocket not in time, equally The phenomenon that dust settling pocket is blocked occurs.
The content of the invention
The present invention provides a kind of coal separation deduster, solves the deashing existing for purge mode that recoiled in original sack cleaner Halfway problem.
To achieve the above object, the technical solution adopted in the utility model is:
Coal separation deduster, including housing, housing inner route clapboard are divided into the air-purifying chamber on top and the dirt pocket of bottom, dedusting The bottom of room is provided with collection funnel, and air inlet is arranged on the side of collection funnel, and dirt pocket is vertically provided with uniform multigroup locellus, Dividing plate corresponding to locellus is provided with through hole, and the bottom of locellus is provided with flap valve and split with collection funnel, and through hole sets the multigroup of suspension Filter bag, the place suitable for reading of filter bag pass through the through hole provided with Venturi tube pipe, set injection tube in air-purifying chamber, injection tube is in the through hole Place top sets injection mouth, and injection tube corresponding to each through hole is one group.
The housing supports integral device provided with support frame, and the top of the housing is provided with the unlatching opened to both sides Door, the lower side of dirt pocket are provided with population, the exit electric brake plate valve of the collection funnel.
The rotating shaft of flap valve is provided with rotating driving system in hull outside, and the injection tube is provided at an outer portion with magnetic valve, spray Blowpipe accesses high-pressure air source, and the rotating driving system is pneumatic operated valve.
The top view cross section of the housing is rectangle, and each locellus is the rectangle with size.
The utility model has the advantage of:Integral dirt pocket is divided into multiple, is each corresponding with filter bag, can the time to every Individual locellus carries out individually recoil deashing, improves efficiency during deashing, improves dust removing effects, avoids air inlet air pressure and back flushing air Recoil failure caused by pressure liquidates, reasonable in design, floor space is small.

Embodiment
The utility model structure as illustrated, coal separation deduster, it is characterized in that, including housing 1, the inner route clapboard 7 of housing 1 It is divided into the air-purifying chamber 2 on top and the dirt pocket 3 of bottom, the bottom of dirt pocket 3 is provided with collection funnel 4, and air inlet 5 is arranged on collection The side of funnel 4, dirt pocket 3 are vertically provided with uniform multigroup locellus 6, and dividing plate 7 corresponding to locellus 6 is provided with through hole, under locellus 6 Portion is split provided with flap valve with collection funnel 4, and through hole sets multigroup filter bag 8 of suspension, and the place suitable for reading of filter bag 8 is provided with Venturi tube 9 pipes set injection tube 10, injection tube 10 sets injection mouth, each through hole above the through hole through the through hole in air-purifying chamber 2 Corresponding injection tube 10 is one group.
Housing 1 supports integral device provided with support frame 11, and the top of the housing 1 is provided with the unlatching opened to both sides Door 16, the lower side of dirt pocket 3 is provided with population 15, the exit electric brake plate valve of the collection funnel 4.
The rotating shaft of flap valve is provided with rotating driving system 12 outside housing 1, and the injection tube 10 is provided at an outer portion with electromagnetism Valve 13, injection tube 10 access high-pressure air source 14, and the rotating driving system 12 is air-leg.
The top view cross section of the housing 1 is rectangle, and each locellus 6 is the rectangle with size.
The operation principle of the present apparatus:The equipment is in the presence of air-introduced machine, air inlet of the gas from deduster bottom containing village In into the collection funnel of deduster bottom carry out dusty gas pretreatment, the larger grit in part due to inertial collision, so The effects such as sedimentation fall directly into collection funnel, and other grits are risen into each locellus of dirt pocket with air-flow, and dust is inhaled It is attached on the outer surface of filter cylinder, the clean gas after filtering enters the air-purifying chamber of upper box through filter cylinder and is collected to air outlet Discharge.Often arrange above filter bag and set an injection tube, injection tube is provided with the injection mouth corresponding with each filter bag, every group of injection tube Magnetic valve is installed in front end, controls magnetic valve
Open, compressed air sprays at a high speed from ejiction opening.Passed through together with 57 times bigger than own vol of induction air Venturi tube enters filter bag.Filter bag, which drastically expands, causes impact shock, makes to be attached to the dust releasing outside filter bag.
As filtering operating mode continues, accumulate in filter cylinder appearance and on dust will be cumulative, will accordingly increase equipment Running resistance in order to ensure the normal operation of system, system control flap valve processed cuts off the air intake passage of a certain room, makes this Room is in air-flow inactive state, is then compressed air pulse reverse gas cleaning, the nature after deashing again through some seconds After sedimentation, then the air intake passage of the room is opened, not only deashing is thorough, it is thus also avoided that the secondary suction of dust caused by jetting deashing It is attached, so by room pneumatic cycle ash removal.
The cleaner shares six operating rooms, wherein five operating rooms are completely in dedusting working condition, another room In completely offline deashing state line by line.The rotation of pulse signal six dirt pockets of control is sent using pulse protocol controller Work, rotation deashing,
The present apparatus uses the independent pulse dust cleaning of each locellus.Ensure that filter bag will not block up reality because dust stratification is excessive, overcome during with ^ Dust is not clean after deashing, in turn ensures that every filter bag with no dead spaces.
