Abstract
The invention provides a double-layer waste gas collection hood. The double-layer waste gas collection hood comprises a hood body and an air inlet in the center of the hood body, the air inlet is externally connected with a draft fan, the hood body is of double-layer structure, the hood is circular and an adjusting valve is arranged at the air inlet of the center of the hood body. The double-layer waste gas collection hood has the advantages that the hood body is of double-layer structure, large suction force can be formed at the edge, and waste gas collection effect is better; the section of the hood body is circular, and suction force is more uniformly distributed; the adjusting valve is arranged at the center of the air inlet and can adjust suction force.
Description
Technical field
The present invention relates to a kind of waste gas recovering device, relate to a kind of double-deck gas sampling cover particularly
Background technology
In reclaimed rubber production line, glue pressing machine is conventional machinery, because generation waste gas, so generally will arrange gas sampling cover on glue pressing machine top, existing gas sampling cover is generally single layer designs, obvious in the negative pressuren zone effect of central authorities, but in neighboring area, especially fringe region, suction just reduces greatly, cause waste gas excessive, collecting effect is bad.And existing gas sampling cover mostly is square, the dead angle of the position of a corner suction especially.
Summary of the invention
The object of this invention is to provide the gas sampling cover that a kind of structure is simple, reasonable in design, fringe region suction increases, especially solve the technical problem of existing gas sampling shroud rim region suction difference.
Technical scheme of the present invention is: a kind of double-deck gas sampling cover, comprises the air-vent at cover body and cover body center, and the external air-introduced machine of air-vent, is characterized in that: described cover body is double-decker.
Further, described cover body is circular.
Further, air-vent place, described cover body center is provided with control valve.
The advantage that the present invention has and good effect are: cover body adopts double-decker, and can form larger suction in edge, gas sampling effect is better; Cover body cross section is set to circle, and suction is more evenly distributed; Air-vent center is provided with control valve, can regulate suction size.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention
In figure:
1, cover body 2, air-vent 3, air-introduced machine
4, control valve
Detailed description of the invention
A kind of double-deck gas sampling cover, comprise the air-vent 2 at cover body 1 and cover body 1 center, the external air-introduced machine 3 of air-vent 2, described cover body 1 is double-decker, inside and outside two-layer.
Further, described cover body 1 cross section is done circular.
Further, air-vent 2 place, described cover body 1 center is provided with control valve 4.
The course of work of this double-deck gas sampling cover is: when glue pressing machine work, open air-introduced machine 3, now air-flow is discharged from cover body 1 bottom and the two-layer middle crack circulation of cover body 1 by air-vent 2, because double-layer structure, the negative pressure formed in edge will be larger, suction is stronger, overcomes the difficult problem that unborn edge suction does not reach.And cover body 1 is designed to circle, the negative pressure value at such double-decker collection cover horn mouth position is more evenly distributed, and ensure that the effect of waste gas is collected by edge.
In addition, at air-vent 2, place is also provided with control valve 4, can regulating air volume, thus regulates suction.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
Claims (3)
