Abstract
The invention discloses a kind of folding air-suction cover, belong to weld fumes processing technology field, the air intake duct of air-suction cover is housed including bottom, the air-suction cover includes support bar, rib support assembly and air-breathing cover, the support bar is fixed on the lower section of air intake duct, the rib support assembly is connected with the support bar, and the air-breathing cover is arranged on rib support assembly.Present apparatus air-suction cover uses very light fire retardant as air-breathing cover, very small to the pulling force of air intake duct, will not damage air intake duct；The air-breathing area of this air-suction cover is big, and larger operating space is provided for Site Welding operation, is advantageous to improve operating efficiency.
Description
Technical field
The present invention relates to weld fumes processing technology field, more particularly to a kind of folding air-suction cover.
Background technology
Weld fumes clarifier is used to weld, cut, polish etc. in process the purification of generation flue dust and dust and to dilute
There is recovery of metal, valuable material etc., a large amount of fine metal particles harmful in atmosphere that suspend can be purified.
The operation principle of weld fumes clarifier is：By blower fan graviational interaction, weldering smoke waste gas is through Universal flexible inhalation arm
Cover mouth inhalation device, back-fire relief net is equipped with air suction arm cover mouth, and bulky grain spark enters filtering by back-fire relief net detention, weldering smoke waste gas
Room, weldering smoke waste gas are filtering indoor moveable, and using gravity and air upflow, the grey drawer of collection is directly down to first by coarse grain flue dust,
Weldering cigarette containing particle dust is obstructed by columnar filter cylinder, and under sieving effect, particle dust is delayed on filter cylinder surface, weldering
After the filtered purification of smoke waste gas, toilet is flowed into by filter cylinder center, then through the discharge up to standard of equipment exhaust outlet.
Air suction arm on weld fumes clarifier is made up of air intake duct and air-suction cover, and traditional air-suction cover has following lack
Point, first, the material of air-suction cover is mostly irony or steel, itself is heavier, so as to produce larger pulling force to air intake duct, for a long time
It is easily damaged air intake duct；Second, the air-breathing area of air-suction cover is small, and height adjusts inconvenience, is not easy to weld larger workpiece.
The content of the invention
To make up the deficiencies in the prior art, the invention provides a kind of folding air-suction cover.
The present invention is achieved through the following technical solutions：
A kind of folding air-suction cover, including bottom are equipped with the air intake duct of air-suction cover, and the air-suction cover includes support bar, umbrella frame branch
Frame assembly and air-breathing cover, the support bar are fixed on the lower section of air intake duct, and the rib support assembly is connected with the support bar,
The air-breathing cover is arranged on rib support assembly.
Preferably, the rib support assembly includes supporting part and connecting portion, supporting part connection air-breathing cover, and connecting portion connects
Support bar is connect, for the connecting portion of the rib support assembly when being slided from bottom to top on support bar, supporting part props up air-breathing cover
Area gradually increase.
Preferably, multiple grooves are offered on the support bar, are provided with the inside of the connecting portion of the rib support assembly
It is corresponding with the groove raised.
Preferably, the air-breathing cover uses flame retardant fabric.
The invention has the advantages that present apparatus air-suction cover uses very light fire retardant as air-breathing cover, to inhaling
The pulling force of tracheae is very small, will not damage air intake duct；The air-breathing area of this air-suction cover is big, is provided for Site Welding operation larger
Operating space, be advantageous to improve operating efficiency.
Brief description of the drawings
The invention will be further described below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the profile of A-A in Fig. 1.
In figure, 1 air intake duct, 2 air-suction covers, 21 support bars, 22 rib support assemblies, 23 air-breathing covers, 221 supporting parts, 222
Connecting portion.
Embodiment
The invention will be further described with reference to the accompanying drawings and examples.
Such as Fig. 1, a kind of folding air-suction cover, including bottom are equipped with the air intake duct 1 of air-suction cover 2, and the air-suction cover 2 includes
Support bar 21, rib support assembly 22 and air-breathing cover 23, the support bar 21 are fixed on the lower section of air intake duct 1, the umbrella frame
Bracket assembly 22 is connected with the support bar 21, and the air-breathing cover 23 is arranged on rib support assembly 22.
The rib support assembly 22 includes supporting part 221 and connecting portion 222, and supporting part 221 connects air-breathing cover 23, even
The connection support bar 21 of socket part 222, the connecting portion 222 of the rib support assembly 22 when being slided from bottom to top on support bar 21,
The air-breathing area that supporting part 221 props up air-breathing cover 23 gradually increases.
Offer 4 grooves on the support bar 21, the inner side of connecting portion 222 of the rib support assembly 22 be provided with
Corresponding 4 projections of groove, such benefit are better able to be fixedly connected with portion 222, and air-suction cover 2 has 4 grades of open surfaces
Product.
To avoid welding spark from causing damage sucting mask 23, air-breathing cover 23 uses flame retardant fabric.
Present apparatus air-suction cover uses very light fire retardant as air-breathing cover, negligible not to the pulling force of air intake duct
Meter, will not damage air intake duct；The air-breathing area of this air-suction cover is big, and larger operating space is provided for Site Welding operation, is had
Beneficial to raising operating efficiency.
