Description
Technical field
The utility model, which belongs to, inhibits dust explosion technical field, and in particular to a kind of piston type explosion suppressor.
Background technology
The design of explosion suppressor is for inhibiting or hindering detonation or flame transmission, by detecting pressure change or infrared
Line detects, and to judge whether explode in industrial equipment, inhibitor (in millisecond) is rapidly introduced into container after confirmation, is hindered
Disconnected flame transmission.
Existing explosion suppressor is substantially what is automatically controlled, due to automatically control sensitive so being widely used, however from
The circuit easy failure easy to aging that dynamic control can increase production cost and automatically control.
Utility model content
The purpose of this utility model is that for increasing production cost existing for the explosion suppressor automatically controlled and automatically controlling
Circuit easy failure easy to aging the problem of, the utility model provides a kind of piston type explosion suppressor.
The technical solution adopted in the utility model is as follows：
A kind of piston type explosion suppressor, including housing, the outward bending of housing lower end forms connecting flange, is set through case top
Explosion suppressant storage room is equipped with, the lower end of Explosion suppressant storage room stretches into the enclosure interior and is sealed end；Explosion suppressant storage room
Cylinder is arranged with outside lower part, the upper end of cylinder and the outer surface of the Explosion suppressant storage room lower part are welded, the lower end of cylinder
It bends inwards to form boss, the cylinder top inner wall is fixedly connected with several adjustable springs, and one end of adjustable spring is freely
End and straight down；
Piston is provided in the cylinder, piston upper surface outwardly convex forms tartar, set on the side wall of the cylinder
There are several spray orifices.
Further limit, it is described that the housing sidewall is provided with pressure detector.
It further limits, alarm is provided on the hull outside wall.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are：
1. the utility model is simple in structure, lowers production cost, solve the circuit automatically controlled easy failure easy to aging
The problem of.
2. setting adjustable spring, when avoiding the pressure in powder carry pipeline from being in normal range (NR), piston is pushed up
And tartar punctures the sealed end of Explosion suppressant storage room so that Explosion suppressant and nitrogen leak out, and cause to waste and so that powder is defeated
Journey is passed through to stop and lose economical.
3. the lower end of cylinder bends inwards to form boss, store indoor Explosion suppressant for Explosion suppressant and when nitrogen discharges or
It is when not having pressure in powder carry pipeline, piston out of cylinder to be released and is fallen into powder carry pipeline.
4. pressure detector is used to detect the pressure in powder carry pipeline, patrol officer is avoided to check at any time.
5. when pressure is more than the preset range of alarm, alarm sends out alarm, is looked into convenient for staff
It sees.
Description of the drawings
The utility model will illustrate by example and with reference to the appended drawing,：
Fig. 1 is the structure diagram of the utility model；
Wherein：1- housings；2- connecting flanges；3- Explosion suppressant storage rooms；4- cylinders；5- boss；6- spray orifices；7- pistons；8-
Adjustable spring；9- sealed ends；10- pressure detectors；11- alarms.
Specific embodiment
All features or disclosed all methods disclosed in this specification or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.It elaborates with reference to Fig. 1 to the utility model.
Embodiment one
The technical solution of the present embodiment is：A kind of piston type explosion suppressor, including housing 1,1 lower end outward bending of housing is formed
Connecting flange 2 is provided with Explosion suppressant storage room 3 through 1 top of housing, and the lower end of Explosion suppressant storage room 3 is stretched into the housing 1
Portion and for sealed end 9；Cylinder 4 is arranged with outside the lower part of Explosion suppressant storage room 3, the upper end of cylinder 4 is stored with the Explosion suppressant
The outer surface welding of 3 lower part of room, the lower end of cylinder 4 bend inwards to form boss 5, and 4 top inner wall of cylinder is fixedly connected
There are several adjustable springs 8, one end of adjustable spring 8 is for free end and straight down；
Piston 7 is provided in the cylinder 4,7 upper surface outwardly convex of piston forms tartar 12, the side wall of the cylinder 4
On be provided with several spray orifices 6.
As shown in Figure 1, Explosion suppressant storage room 3 is packed into Explosion suppressant in advance and inert gas causes in Explosion suppressant storage room 3
Pressure be slightly larger than powder explosion critical pressure, connect by connecting flange 2 with powder carry pipeline, when powder carry pipeline
When interior pressure is in normal range, piston 7 compress adjustable spring 8, but tartar 12 not with 3 lower end of Explosion suppressant storage room
Sealed end 9 contacts；It is when the pressure in powder carry pipeline is more than the critical pressure of powder explosion, piston 7 is axial along cylinder 4
Push up and compress adjustable spring 8, tartar 12 contacts with the sealed end 9 of 3 lower end of Explosion suppressant storage room and pricks, Explosion suppressant and
Inert gas is sprayed and is sprayed into cylinder 4, while piston 7 is axially downwardly pushed away along cylinder 4 from the place of puncturing, finally tight with boss 5
Contiguity is touched, and Explosion suppressant and inert gas are sprayed and sprayed to from spray orifice 6 and extinguish fire in powder carry pipeline and inhibit the hair of explosion
It is raw；Adjustable spring 8 is set, when avoiding the pressure in powder carry pipeline from being in normal range (NR), piston 7 is pushed up and tartar
The sealed end 9 of Explosion suppressant storage room 3 is punctured so that Explosion suppressant and nitrogen leak out, and cause to waste and cause powder carry mistake
Journey stops and loses economy, and the lower end of cylinder 4, which bends inwards, to form boss 5, for the Explosion suppressant and nitrogen in Explosion suppressant storage room 3
When there is no pressure when gas discharges or in powder carry pipeline, piston 7 out of cylinder 4 is released and is fallen into powder carry pipeline.
Embodiment two
On the basis of embodiment one, the technical solution of the present embodiment is：It is described that 1 side wall of housing is provided with pressure
Force detector 10.Alarm 11 is provided on 1 lateral wall of housing.
As shown in Figure 1, pressure detector 10 is used to detect the pressure in powder carry pipeline, patrol officer is avoided to look at any time
It sees；When pressure is more than the preset range of alarm 11,11 devices of alarm send out alarm, are checked convenient for staff.
