Abstract

The utility model relates to simple spark arrester, including exhaust pipe, exhaust pipe outlet side is connected with to the spiral type pipe that Mars is extinguished in discharge exhaust gas；The outlet side and spiral type pipe junction of exhaust pipe seal；By being connected with spiral type pipe in exhaust pipe outlet side, after exhaust gas with Mars is discharged into spiral type pipe, advance with helix-type channel, impact several times can occur for Mars and the inner wall of spiral type pipe during advance, and it is carried out by discharge air-flow air-cooled, so that Mars extinguishes, discharge gas reaches the safety requirements such as fire prevention, explosion-proof.

Description

A kind of simple spark arrester

Technical field

The utility model relates to Mars to extinguish technical field, more specifically to a kind of simple spark arrester.

Background technique

Spark arrester be it is a kind of elimination Mars, spark device, design principle mainly be depressured slow down, change direction, Mesh filtering and cooling.Its application is the field for needing to be discharged into danger zone with the exhaust gas of Mars or spark Institute or the exhaust gas possibly into danger zone situation, in short, Mars or spark may be had in exhaust gas, and exhaust gas may flow When entering danger zone, according to national security production requirement, it should be exhaust gas and install spark extinguishing device additional.

In various kinds of equipment, daily production and living it is most common to spark arrester be that the effective spark of engine exhaust is put out Go out device, and structure is generally labyrinth type, water-bath type, grid-plate type, laminated type and combined, these arc arresters have centainly Flame-out ability, but structure is more complicated, it is difficult to be applied in the middle of medium and small equipment positive-pressure explosion-proof design.

Utility model content

The technical problem to be solved by the present invention is in view of the above drawbacks of the prior art, provide a kind of simple fire Star extinguisher.

The technical scheme adopted by the utility model to solve the technical problem is as follows:

Construct a kind of simple spark arrester, wherein including exhaust pipe, the exhaust pipe outlet side is connected with The spiral type pipe that Mars in discharge exhaust gas is extinguished；The outlet side of the exhaust pipe and the spiral type pipe junction Sealing.

Simple spark arrester described in the utility model, wherein the exhaust pipe passes through with the spiral type pipe Connector sleeve connection；The connector sleeve be internally provided with matched first silica gel sheath of the exhaust pipe outer diameter, and with it is described Matched second silica gel sheath of the outer diameter of spiral type pipe；Be provided on the connector sleeve the fixed exhaust pipe of multiple abuttings with And the screw of the spiral type pipe, and with the one-to-one screw hole of screw.

Simple spark arrester described in the utility model, wherein the exhaust pipe and the spiral type pipe are welded It is fixed.

Simple spark arrester described in the utility model, wherein exhaust pipe tail end end face is machined with first Annular tooth mouth；The spiral type pipe end face is provided with and the first annular matched second annular tooth mouth of tooth mouth.

Simple spark arrester described in the utility model, wherein multiple be staggered is provided in the spiral type pipe Barrier flaps.

Simple spark arrester described in the utility model, wherein the barrier flaps semicircular in shape.

The utility model has the beneficial effects that: by being connected with spiral type pipe, band Mars in exhaust pipe outlet side Exhaust gas be discharged into spiral type pipe after, advance with helix-type channel, Mars and the inner wall of spiral type pipe can occur during advance Impact several times, and it is air-cooled by discharge air-flow progress, and so that Mars extinguishes, discharge gas reaches the safety requirements such as fire prevention, explosion-proof.

Detailed description of the invention

In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, below in conjunction with attached drawing and reality Applying example, the utility model is described in further detail, and the accompanying drawings in the following description is only section Example of the invention, for this For the those of ordinary skill of field, without creative efforts, it is attached to can also be obtained according to these attached drawings other Figure:

Fig. 1 is the simple spark arrester structural schematic diagram of the utility model preferred embodiment；

Fig. 2 is the simple spark arrester connection cross-sectional view of the utility model preferred embodiment.

Specific embodiment

It is practical below in conjunction with this in order to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer Technical solution in new embodiment carries out clear, complete description, it is clear that described embodiment is the portion of the utility model Point embodiment, rather than whole embodiments.Based on the embodiment of the present invention, those of ordinary skill in the art are not paying creation Property labour under the premise of every other embodiment obtained, belong to the protection scope of the utility model.

The simple spark arrester of the utility model preferred embodiment is as shown in Figure 1, simultaneously referring to Fig.2, including that exhaust gas is arranged Pipe 1 is put, 1 outlet side of exhaust pipe is connected with to the spiral type pipe 2 that Mars is extinguished in discharge exhaust gas；Exhaust pipe 1 Outlet side and 2 junction of spiral type pipe seal；By being connected with spiral type pipe 2 in 1 outlet side of exhaust pipe, with Mars After exhaust gas is discharged into spiral type pipe 2, advance with helix-type channel, Mars and the inner wall of spiral type pipe 2 can occur during advance Impact several times, and it is air-cooled by discharge air-flow progress, and so that Mars extinguishes, discharge gas reaches the safety requirements such as fire prevention, explosion-proof； The simple spark arrester that structure is simple, manufacturing cost is cheap, outer dimension is small, the extinguisher can satisfy medium and small positive pressure The blow-out requirement of antiknock device.

As depicted in figs. 1 and 2, exhaust pipe 1 is connect with spiral type pipe 2 by connector sleeve 3；It is arranged inside connector sleeve 3 Have and matched first silica gel sheath 30 of 1 outer diameter of exhaust pipe, and matched second silica gel sheath 31 of outer diameter with spiral type pipe 2； Multiple screws 32 for pushing against fixed exhaust pipe 1 and spiral type pipe 2 are provided on connector sleeve 3, and a pair of with screw 32 1 The screw hole (not identified in figure) answered.

It should be noted that the connection type of exhaust pipe 1 and spiral type pipe 2 can also be using the side being welded and fixed Formula.

As depicted in figs. 1 and 2,1 tail end end face of exhaust pipe is machined with first annular tooth mouth；2 end face of spiral type pipe is set It is equipped with and the matched second annular tooth mouth of first annular tooth mouth；Contraposition when being easily installed.

As depicted in figs. 1 and 2, multiple barrier flaps 20 being staggered are provided in spiral type pipe 2；Further it is significantly increased Mars collision probability, while it is short that the length of spiral type pipe 2 is further done.
