Abstract
The invention relates to an orifice-plate spark particle obstructing device which is applied on a positive pressure explosion-proof control cabinet. The obstructing device contains an exhaust pipe, an orifice plate and a shield. The exhaust pipe is fixedly arranged through an air exhaust opening of the positive pressure explosion-proof control cabinet. At least one orifice plate is fixed on the internal end of the exhaust pipe. The orifice plate is equipped with a plurality of through holes. The shield is sleeved on the orifice plate. The inner wall of the shield is fixedly connected with the edge of the orifice plate. There is a certain distance from the edge of the shield opening to the inner wall of the positive pressure explosion-proof control cabinet. The device has a simple and ingenious structure, is arranged at the air exhaust opening of the positive pressure explosion-proof control cabinet, and can be used to obstruct and intercept sparks and heat particles generated during the operation process of the explosion-proof control cabinet to discharge into an external dangerous environment of the control cabinet through the orifice plate, the shield and the exhaust pipe. Thus, the cooling distance of the spark particles is increased, and safe operation reliability of the positive pressure explosion-proof control cabinet is raised. The orifice plate, the shield and the exhaust pipe are all prepared from a metal material, the obstructing material is optimized, and the service life of the obstructing device is prolonged.
Description
Technical field
The present invention relates to a kind of orifice-plate type spark particulate blocking device that is applied on the positive-pressure explosion-proof switch board.
Background technology
In the prior art, the exhaust outlet of positive-pressure explosion-proof switch board normally adopts rubber slab to the baffling device of spark particle, and it is simple in structure, easy ageing, and long-time running can not be guaranteed the effective obstruct to the spark particle, influences the safe handling of positive-pressure explosion-proof switch board.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art; A kind of orifice-plate type spark particulate blocking device of simple and ingenious structure is provided; It adopts AND DEWATERING FOR ORIFICE STRUCTURE; The spark that produces in the positive-pressure explosion-proof switch board or hot particle are cooled off and intercept, improved the safe operation reliability of positive-pressure explosion-proof switch board in the explosion risk environment.
According to technical scheme provided by the invention: orifice-plate type spark particulate blocking device; It is characterized in that: comprise blast pipe, orifice plate and guard shield; Said blast pipe fixedly is located in the exhaust outlet of positive-pressure explosion-proof switch board; Be fixed with at least two orifice plates in blast pipe the inner, have a plurality of through holes on the orifice plate; Said guard shield is enclosed within on the orifice plate, and the guard shield inwall is connected fixing with the orifice plate edge, and the inwall of the edge of guard shield opening and positive-pressure explosion-proof switch board leaves a determining deviation.
As further improvement of the present invention, the through hole on the said different orifice plates staggers each other, and orifice plate is the closer to the air inlet end of blast pipe, and the through hole on this orifice plate is the closer to blast pipe.
As further improvement of the present invention, the quantity of said orifice plate is two.
As further improvement of the present invention, said blast pipe is threaded or is welded in the exhaust outlet of positive-pressure explosion-proof switch board, and said orifice plate is threaded or is welded on the blast pipe, and said guard shield inwall and the welding of orifice plate edge are fixing.
As further improvement of the present invention, said blast pipe, orifice plate and guard shield all are to adopt metal material to process.
The present invention compared with prior art; Advantage is: simple and ingenious structure of the present invention; It is arranged on the exhaust ports of positive-pressure explosion-proof switch board; Intercept the spark that produces in the interception flame proof switch board running and hot particulate emission to being discharged in the outside hazardous environment of switch board through parts such as orifice plate, guard shield and blast pipes, increased the cooling distance of spark particle, improved the safe operation reliability of positive-pressure explosion-proof switch board.Said orifice plate, guard shield and blast pipe all are to adopt metal material to process, and have optimized barrier material, prolong the service life of baffling device.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
As shown in the figure, the orifice-plate type spark particulate blocking device among the embodiment mainly is made up of parts such as blast pipe 1, orifice plate 2 and guard shields 3, and described blast pipe 1, orifice plate 2 and guard shield 3 all are to adopt metal material to process.
As shown in Figure 1, said blast pipe 1 fixedly is located in the exhaust outlet of positive-pressure explosion-proof switch board with the mode that is threaded or welds, and is fixed with two orifice plates 2 in blast pipe 1 the inner with the mode that is threaded or weld, and has a plurality of through hole 2a on the orifice plate 2; Said guard shield 3 is enclosed within on the orifice plate 2, and guard shield 3 inwalls and the welding of orifice plate 2 edges are fixing, and the edge of guard shield 3 openings and the inwall of positive-pressure explosion-proof switch board leave a determining deviation, so that the gas in the positive-pressure explosion-proof switch board can be discharged.
As shown in Figure 1, the through hole 2a on the said different orifice plates 2 staggers each other, and orifice plate 2 is the closer to the air inlet end of blast pipe 1, and the through hole 2a on this orifice plate 2 is the closer to blast pipe 1.Can more effectively intercept like this and discharge spark or the hot particle that is mingled with in the gas, make gas in the process of circulation, flow to the air inlet end of blast pipe 1 gradually simultaneously.
During concrete the application, the gas of discharging in the positive-pressure explosion-proof switch board gets into from guard shield 3 openings, passes the through hole 2a on the orifice plate 2 successively, gets into blast pipe 1; In the process of circulation of gas; Spark that possibly be mingled with in the gas or hot particle obtain cooling and intercept; After after blast pipe 1 is discharged to the outside explosion risk gaseous environment of positive-pressure explosion-proof switch board, can not bring extraneous explosion dangerous, make the safe operation of positive-pressure explosion-proof switch board.
