Description
Technical field
The invention belongs to the nonflame pressure release module on pipeline, specifically a kind of dust nonflame bleeder.
Background technology
Nonflame bleeder is mainly used in the industries such as grain, metallurgy, chemical industry, electric power, pharmacy, machining, concrete application
On the official road that the equipment such as cyclone separator, deduster, dust collector, filtering cartridge filter, Geldart-D particle are connected.
In the prior art, nonflame bleeder is connected on pipeline by the flange of both sides, its internal fire suppression module master
If the corrugated plating formed by steel plate compacting forms.This nonflame bleeder mainly has the disadvantage that：1. percent of pass is general only
30% or so can be reached, in the case where not changing pipeline valid circulation area, it is necessary to which the latus rectum of nonflame bleeder is increased
It is more than three times；2. because corrugated plating is formed by steel plate compacting, weight is heavier, adds the overall weight of nonflame bleeder
Amount, it is necessary to bear shear stress using large diameter bolt when on pipeline；3. maintaining difficulty is, it is necessary to both sides
Flange take apart and nonflame bleeder could be pulled down, then carry out maintaining；4. after venting of dust explosion, venting of dust explosion barrier plate is torn
Split, it is therefore desirable to venting of dust explosion barrier plate is frequently changed, so as to increase maintenance cost.5. after venting of dust explosion piece venting of dust explosion, due to venting of dust explosion piece by
Destroy, extraneous air can be back in pipeline and pollute.6. the Opening pressure of venting of dust explosion piece is fixed, therefore in practicality not
Greatly.
The content of the invention
It is an object of the invention to：In order to solve nonflame bleeder maintenance suffering and repeatedly practical technical problem, carry
For it is a kind of for ease of maintenaince and can nonexpondable nonflame bleeder have it is simple in construction, for ease of maintenaince with nonexpondable spy
Point.
The technical solution adopted by the present invention is as follows：
It is a kind of for ease of maintenaince and can nonexpondable nonflame bleeder, including support frame, venting of dust explosion barrier plate and venting of dust explosion chamber

In the entrance point of venting of dust explosion cavity, it is characterised in that the exit of the venting of dust explosion cavity is provided with flame retardant bed, and the flame retardant bed uses
Copper material is made, and the outlet of the venting of dust explosion cavity is provided with venting of dust explosion cylinder, institute for sector, the venting of dust explosion inside cavity from the side
State venting of dust explosion cylinder and be internally provided with back-moving spring, described back-moving spring one end is connected with venting of dust explosion barrier plate, and the back-moving spring is another
End is connected with supporting plate, and the supporting plate is located at the bottom of venting of dust explosion casing.
Further preferably, the entrance of the venting of dust explosion cavity is provided with flanged plate.
Further preferably, the flame retardant bed is made by being at least two layers of stainless steel mesh.
Further preferably, it is provided with rubber sheet gasket between the venting of dust explosion barrier plate and flanged plate.
Further preferably, the inner edge edge of the flanged plate is provided with the mounting groove of circle, the rubber sheet gasket installation
In the mounting groove.
Further preferably, it is provided with signal supervisory instrument on venting of dust explosion barrier plate.
Operation principle：The present invention is arranged on pipeline, when the equipment such as deduster or dust collector generation dust is quick-fried
When fried, flame and shock wave are simultaneously delivered to letting out positioned at emission device front end by pressure rise in equipment by pipeline
Quick-fried, because the pressure in pipeline has exceeded the Opening pressure of venting of dust explosion piece, now the air pressure in external pipe is more than back-moving spring
Opening pressure, the venting of dust explosion barrier plate pushed up out, and high pressure draught is entered inside nonflame bleeder by venting of dust explosion cylinder, impact
Ripple and flame are by reaching the flame retardant bed of emission device after venting of dust explosion piece, the pressure in pipeline is reduced rapidly, and flame is hindered
Fire bed stops, and imperfect combustion dust is stopped by flame retardant bed, after the pressure releasing in pipeline,
Under the extruding of back-moving spring, venting of dust explosion barrier plate can Rapid reset so as to realize the closing of bleeder reset, effectively prevent
Extraneous air-flow falls in flowing into pipeline.
In summary, by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
1. the present invention is after the pressure releasing in pipeline, under the extruding of back-moving spring, venting of dust explosion barrier plate can be fast
Position is replied immediately so as to realize that the closing of bleeder resets, effectively prevents the air-flow in the external world from falling in flowing into pipeline.
2. venting of dust explosion barrier plate of the present invention is made of copper material, be not easy to be destroyed, venting of dust explosion barrier plate and venting of dust explosion cylinder coordinate so as to
Realization is used repeatedly.
3. bottom flanged plate and gasket seal that the present invention is set can effectively ensure that the sealing of device.
4. by adjusting the decrement of spring, the flexible modulation of Opening pressure of the present invention can be realized so that this hair
It is bright to meet different venting of dust explosion scenes.
