Abstract
A pressure explosion venting bolt device for a spray chamber comprises pressure buckles and pressure seats. The end portion of each pressure buckle is an inclined plane. Each pressure seat is in a hollow structure. A notch is disposed in one sidewall of each pressure seat. An adjustable screw is arranged on the other sidewall of a frame-type pressure seat. One end of a spring is fixed on the inner wall of each pressure seat and abuts against the adjustable screw. The other end of the spring is connected with the back side of one movable baffle. One end of the movable baffle is fixed on the sidewall of one pressure seat through a hinged shaft. The other end of the movable baffle extends out of the sidewall face of the pressure seat through the notch disposed in one sidewall face of the frame-type pressure seat. When the pressure explosion venting bolt device is in a normal state, the extension end of each movable baffle abuts against the inclined plane on the end portion of one pressure buckle. The pressure explosion venting bolt device can automatically open a safety gate without any motive power when the fixed explosion venting pressure is exceeded, and therefore the pressure explosion venting bolt device plays roles of decompression and anti-explosion, and is energy-saving, environmental-friendly, simple in manufacturing, low in cost, and convenient to install and use.
Description
Technical field
The utility model relates to pressure venting of dust explosion pin device, relates in particular to the explosion venting device on the work safety door that applies to the paint spray booth.
Technical background
Because country is to the requirement of environmental protection, the plant equipment surface lacquer need to carry out in the airtight paint spray booth of specialty, then by supply and exhaust device and emission-control equipment the high-altitude is processed and effectively be discharged into to the gas sampling that produces.Because the supply and exhaust air quantity in the paint spray booth is larger, and a pressure relief opening just must be arranged in such one airtight paint spray booth, the wallboard that cause under than Wind Volume and Action of Wind pressure inside, paint spray booth when preventing that exhaust system is not normal is out of shape and bursts apart.
The paint spray booth is provided with manually operated door in the prior art, but can't automatically open in needs after the manually operated door locking.In addition with the safety door of electrical control, its electric control gear parts are many in the prior art, need the combination of control assembly and action component chain, make complicatedly, and the cost cost is relatively high again, and control signal is malfunctioning just can't move.
The utility model content
The applicant improves for above-mentioned shortcoming of the prior art, a kind of pressure venting of dust explosion pin device for the paint spray booth is provided, when air-supply air quantity in the paint spray booth (can set) to a certain extent greater than air draft the time safety door can need not power and automatically open, play the pressure-relief explosion-proof effect, and it makes simple, with low cost, install and use all very convenient.
The technical solution of the utility model is as follows:
The pressure venting of dust explosion pin device that is used for the paint spray booth, comprise pressure buckle, pressure seat, the end of pressure buckle is the inclined-plane, pressure seat is hollow-core construction, one sidewall of pressure seat has breach, another sidewall of shaped as frame pressure seat is installed adjustment screw, spring one end be fixed in the pressure seat inwall and with the adjustment screw butt, the other end is connected with the dorsal part of sideboard, sideboard one end is fixed on the sidewall of pressure seat by hinge, the other end extends to outside the side wall surface of pressure seat by the breach that described shaped as frame pressure seat side wall surface has, when this pressure venting of dust explosion pin device is in normal condition, and the described end chamfer butt of the described elongated end of sideboard and pressure buckle.
Its further technical scheme is:
Described pressure buckle is hollow-core construction;
Termination outside the sidewall that extends to pressure seat of described sideboard is equipped with roller;
The side wall surface of described pressure buckle relative pressure seat is the inclined-plane, and when having venting pressure to apply, the described side wall inclined plane of the described elongated end of sideboard from the described end chamfer of pressure buckle to pressure buckle slides, and realizes the pressure venting of dust explosion.
Technique effect of the present utility model:
The utility model need not any power just can be when surpassing certain venting pressure automatic opening safety door, thereby play the pressure-relief explosion-proof effect, its energy-conserving and environment-protective are made simply, with low cost, install and use all very convenient.In addition, this device can substitute the originally door lock effect of work safety door, and no matter the people can easily open the door by door handle indoor or outdoor.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
Please consult simultaneously Fig. 1, Fig. 2, Fig. 3, Fig. 4, the utility model comprises the pressure buckle 3 that is installed on the door-plate 1, be installed in the pressure seat 4 on the doorframe 2, the end of pressure buckle 3 is the inclined-plane, pressure seat 4 is hollow-core construction, one sidewall of pressure seat 4 has breach, another sidewall of shaped as frame pressure seat 4 is installed adjustment screw 5, spring 6 one ends be fixed in pressure seat 4 inwalls and with adjustment screw 5 butts, the other end is connected with the dorsal part of sideboard 7, sideboard 7 one ends are fixed on the sidewall of pressure seat 4 by hinge 8, the other end extends to outside the side wall surface of pressure seat 4 by the breach that described shaped as frame pressure seat 4 side wall surfaces have, the termination of this end is equipped with roller 9, when this pressure venting of dust explosion pin device is in normal condition, the described end chamfer butt of the described elongated end of sideboard 7 and pressure buckle 3.
Operation of the present utility model is as follows:
See Fig. 4, without under the External Force Acting, the sideboard 7 of pressure seat 4 withstands pressure under the elastic force effect of spring 6 and buckles 3, thereby makes safety door be in closed condition; See Fig. 5, when having venting pressure F to apply (adjustable settings), pressure buckle 3 outside Compressive activities baffle plates 7, the side wall surface of pressure buckle 3 relative pressure seats 4 is the inclined-plane, and the described side wall inclined plane of the described elongated end of sideboard 7 from the described end chamfer of pressure buckle 3 to pressure buckle 3 slides, and sideboard 7 is forced to indent after extruding, force spring 6 to shrink, thereby break away from sideboard 7 scopes, reach the effect of automatic opening safety door door, realize the pressure venting of dust explosion.For opening pressure, can when mounted as required, come the pressure of regulating spring 6 to set and regulate with chock by adjustment screw 5.
Above description is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range within protection domain of the present utility model, can be done any type of modification referring to claim.
