Description
Technical field
The utility model relates to the double-layer combined decompression anti-explosion device of a kind of diaphragm gravity, belongs to bag dust collector accessory technical field.
Background technique:
Decompression anti-explosion device is the vitals that is used for explosion-proof bag dust collector in the dust explosion risk place.According to the explosion-proof release area of decompression anti-explosion device, on the positive external wall slab of every explosion-proof cleanner bag chamber, need to install some these decompression anti-explosion devices usually.Decompression anti-explosion device has two important indicators, at first is the Security of pressure-relief explosion-proof, and flameproof apparatus can be guaranteed the safety that equipment uses according to predefined venting of dust explosion pressure venting of dust explosion.Next is for satisfy the sealing needs, reduce and leak out as far as possible.Existing decompression anti-explosion device has two kinds of heavy hammer type and explosion-proof locking-types.The heavy hammer type decompression anti-explosion device is made up of gate seat housing, door closure, counter weight, sealing joint strip, when the dust collector pressure inside surpasses certain pressure, door closure is opened release pressure automatically, after the gas release, door closure returns to the original place by the weight of weight, and its release pressure is adjusted by the position of adjusting counter weight.Explosion-proof locking-type decompression anti-explosion device is made up of gate seat housing, door closure, Explosion-proof Lock, sealing joint strip, when the dust collector internal pressure surpasses the Explosion-proof Lock setting pressure, door closure is opened release pressure, but door closure is difficult to return to the original place, and its release pressure is adjusted by the position of adjusting the Explosion-proof Lock lock core.
Above-mentioned two kinds of decompression anti-explosion devices all are that individual layer unloads laminated structure, all carry out pressure by opening of door closure and discharge, and exist venting of dust explosion pressure to be difficult to the problem of stable control.And owing to adopt the individual layer door, and its poor sealing performance, the air leak rate of air curtain height because of bag dust collector is a negative pressure mode, causes fresh air to be inhaled into deduster inside again easily, for the condition that provides is provided deduster inside coal dust.In addition, because the sealing joint strip on the door closure directly contacts with the door edge of gate seat housing, because of bag dust collector can produce little vibration under the negative pressure mode operation, bad adhesive tape can be cut in the door edge, and time one length will be severed adhesive tape, causes seriously and leaks out.The 4th, the door closure of explosion-proof locking-type decompression anti-explosion device relies on explosion-proof dead bolt and cylindrical rollers to carry out mechanical engagement and compresses, after door closure is being opened, because of the mechanical part resistance is difficult to return to the original place, if untimelyly after release takes place manually adjust recovery, can cause a large amount of fresh airs to be inhaled into deduster inside, will lead to bigger equipment and personal safety accident.
Summary of the invention
Technical problem to be solved in the utility model: provide a kind of good seal performance, the double-layer combined decompression anti-explosion device of diaphragm gravity of pressure release safety and stability.
Its technological scheme is: the double-layer combined decompression anti-explosion device of a kind of diaphragm gravity, comprise the explosion proof door gate seat housing that is welded on the positive wallboard of deduster, the top explosion proof door door closure on the deduster wallboard that is connected through the hinge, and the counter weight that is arranged on the door closure outer lower portion by depression bar, it is characterized in that: be provided with flanging around the door closure of described explosion proof door, the corresponding baffle plate that is provided with in door closure bottom in the flanging forms groove with flanging, and groove is embedded in square adhesive tape; The bottom of door closure is connected with shrouding by the horizontal and vertical stiffening rib of all establishing, and is laid with thermal insulating material between door closure and the shrouding; " U " type adhesive tape that the door of gate seat housing combines along the square adhesive tape coupling that last bonding one is enclosed and door closure four limit grooves are embedded in; On the inner flange frame of gate seat housing by fastening piece outward-dipping from top to bottom be fixed with explosion-proof diaphragm.
Around the above-mentioned explosion-proof diaphragm with the joint of the inner flange frame of gate seat housing, by rubber plate and pressing plate wrapped folder.
Compare with existing decompression anti-explosion device, the utility model has the advantages that:
1, this decompression anti-explosion device is the double-layer explosion-proof structure, explosion-proof diaphragm is set as first layer pressure-relief explosion-proof mechanism on the gate seat housing in the explosion proof door door closure, door at the gate seat housing has the door closure of counter weight and adhering and sealing adhesive tape as second layer pressure-relief explosion-proof mechanism along outer the installation, this door closure and explosion-proof diaphragm are arranged in parallel and keep certain distance, so when the dust collector internal pressure surpasses setting pressure, explosion-proof diaphragm as first layer promptly breaks, the door closure of thereupon opening the second layer is release pressure in time rapidly, thereby problems such as the difficult control of venting of dust explosion pressure have been solved effectively, improve the Security and the stability of pressure-relief explosion-proof, guaranteed the safe operation rate of equipment.
2, this device sealing effect is better, can guarantee that this part air leak rate of air curtain is lower than original technology, avoid too much oxygen to enter dust collector, increased the Safety performance of dust collector, reduce fresh air as far as possible and be inhaled into deduster inside, avoid entering the security incident that causes the inner coal dust of deduster to fire because of too much oxygen.
3, sponge adhesive tape on the door closure and door can farthest guarantee the sealing between door closure and door edge along the last soft way of contact of sandwich rubber strip adoption.
4, lay the dewfall that thermal insulation layer can effectively prevent the inboard dust-containing airflow of the inner explosion-proof diaphragm of deduster at the door closure internal surface, avoid sticking with paste the bag phenomenon, improve the filter bag ash removal effect, improve filter efficiency, prolong life of bag filter.
