Plate is fixed with air inlet on partition board.Deduster gas tank 10 is equipped with by fixing piece 11 on side outside the enclosure, is store in deduster
On gas tank one end filter 13 and shut-off valve 12 are connected with by articulation 17, to silk 18 and carbon steel pipe.The deduster air storage
Tank top is connected with high-pressure hose 9, deduster diaphragm valve 8, jet pipe 6 and weld ell 21, the centrifugal blower by clip 19
By being flexible coupling 23, clip and shell air inlet is connected to box cover.Cabinet door 4 is housed, in babinet on the babinet side
Star-like handle 5 is housed on door.
In the present embodiment, the suitable for reading of the filter cylinder 7 connect to form seal cavity with box house.
In the present embodiment, the deduster diaphragm valve uses submerged pulse diaphragm valve arrangement.
In the present embodiment, pulse valve shield 20 is housed on the deduster diaphragm valve.
In the present embodiment, the centrifugal blower is affixed with box cover by flange, is set between flange and box cover
There is seal gasket.
In the present embodiment, seal gasket is equipped between the babinet and box cover.
In the present embodiment, the filter cylinder 7 selects polyurethane filter cylinder, and with acid and alkali-resistance, corrosion-resistant, explosion-proof performance is strong, mistake
Filtering surface product is big, grease-proof and waterproof, filter efficiency are high, processing air quantity is big, intensity is high, pulling force is big, wearability is strong, filtering accuracy is high, fortune

Etc. advantages, filter cylinder be easy to deashing, it is convenient to install and maintain, service life is long the features such as.
The pedestal must be welded in the silo roof of silo, must ensure horizontal, the vertical and circularity of pedestal, when necessary in flange
Sealed silicone is stamped on face.When dust-extraction unit is installed, maintenance door is opened when should also provide enough spaces to safeguard.
The deduster gas tank 10 is mainly used for stablizing pipeline and the pressure in pulse dust collector gas bag and tolerance.Originally it removes
Dirt device gas tank uses welding structure, and form is more, and gas tank belongs to pressure vessel, must pressing force Vessel Design and manufacture.This
In embodiment, deduster gas tank is circle, volume size according to air supply system air consumption and retention time how much, volume root
It is determined according to required air supply within a certain period of time.Required gas tank, air storage are supplied for independent deduster
The configurating filtered device, shut-off valve on tank.
The submerging pulse valve of this dust-extraction unit is to remove filter medium (cloth bag or filter by the method for blowing pressurized air
Cylinder) on the dust that adheres to；There may be a few group pulse valves according to the size of deduster, open set of pulses valve every time and controlled to remove it
The part cloth bag of system or the dust of filter cylinder, and other cloth bags or filter cylinder normal work, a lower set of pulses after a period of time
Valve is opened, and the dust of next part filter cylinder is cleared up.
The submerging pulse valve of this dust-extraction unit claims submerged using the installation method being submerged in gas bag.It and its
He compares structure type, reduces circulating resistance, reduces injection bleed pressure, thus can be suitably used for the low occasion of pressure, and
Energy consumption can be reduced and extend the diaphragm service life.
Submerging pulse valve operation principle is：Submerging pulse valve is that pulse valve is divided into former and later two rooms by diaphragm, when connecing
When logical compressed air, compressed air enters rear gas chamber by airflow hole, and diaphragm is close to the gas outlet of valve by rear gas chamber's pressure at this time,
Pulse valve is closed.When the electric signal of pulse control instrument makes pulse valve armature move, valve rear gas chamber air vent is opened, after
Gas chamber presses rapidly, and diaphragm movement, compressed air is blown by valve delivery outlet, and pulse valve is in open state.Moment sprays at this time
Go out compressed air.Pulse control instrument electric signal disappears, and pulse valve armature resets, rear gas chamber's deflation bore closure, rear gas chamber's pressure
Power raising makes diaphragm be close to valve outlet, and pulse valve is closed again.
The operation principle of the utility model is：
Silo roof dust-extraction unit dusty gas enters the filter cylinder in babinet by opening wide flange port, and dusty gas penetrates filter cylinder mistake
Filter is that net gas enters air-purifying chamber, then through air-purifying chamber exhaust outlet, is drained by centrifugal blower.Dust accumulates the outer surface for being attached to filter cylinder, and
It is continuously increased, the resistance of dust-extraction unit is made constantly to increase, to make equipment resistance be no more than 1200Pa, dust-extraction unit can interrupted work
Make, need to periodically remove dust on filter bag.DMC series of pulses, which is blown dust-extraction unit deashing, to be started by cyclelog timing sequence
Pulse valve makes compressed air in gas tank (0.5~0.7MPa) be sprayed by jet pipe eyelet and (be claimed First air) and is induced by Venturi tube
It is several times as much as the surrounding air (claiming Secondary Air) of First air, shakes off dust into filter cylinder and along with the effect of the negative direction of air-flow, it is attached
Dust in filter cylinder surface is detached from rapidly filter bag and falls into ash bucket or ash cellar, reaches the mesh of deashing collection.With easy to operate, deashing
Continuously, resistance is stable, high, the internal without motion parts of the rate of filtration, designs the features such as simple, is a kind of dynamical dedusting dress
It sets.
Embodiment described in the utility model attached drawing is exemplary, and is only used for explaining the utility model, and cannot be managed
Solution is limitations of the present invention.
