2The welding machine implementation and operation, produce amounts of dust and smog in the arc-welding welding process, these dust and smog reverberate in air and have had a strong impact on the shopwork environment that is welded, simultaneously serious harm employee health.In order to address this problem, that main buying is conventional single station CO at present
2Cleaner, this occupation area of equipment is big, and maintenance of equipment is complicated, and cost is roughly equal to 60,000 yuan of RMB than higher every simultaneously, in conjunction with conventional single station CO
2Cleaner, and a single station dust discharge arc-welding anchor clamps of enforcement improvement on the basis of household smoke exhaust ventilator principle make it dedusting and the anchor clamps that freeze effectively combine, and greatly reduce manufacturing cost, save the space, have improved employee's operating environment simultaneously.
Summary of the invention
The present invention has designed a kind of single station dust exhausting equipment that is welded, and the dust and the pollution of smog that unskilled labourer position arc-welding welding such as the existing blast pipe suspension hook that is welded of the technical problem of its solution are produced cause personnel's actual bodily harm easily and have conventional single station CO now
2Cleaner costs an arm and a leg.
In order to solve the technical problem of above-mentioned existence, the present invention has adopted following scheme:
A kind of single station dust exhausting equipment that is welded; Comprise dust return air inlet (1), dust return duct (2), the cotton holder (3) of activated filter film, air exhauster (4) and switch (8); It is characterized in that: said dust return air inlet (1) is positioned at the top of welding work pieces (6); Said dust return air inlet (1) is connected with the cotton holder of activated filter film (3) upper end through said dust return duct (2); The cotton holder (3) of activated filter film lower end is connected with air exhauster (4), and said air exhauster (4) is fixed on weld jig basal plane (5).
Further, dust return air inlet (1), dust return duct (2), the cotton holder (3) of activated filter film and air exhauster (4) combination back form an inverted U structure.
Further, dust return duct (2) is an elastomeric material, on dust return duct (2), is with bourdon tube (9) and positions.
Further, the cotton holder of activated filter film (3) that is positioned between dust return duct (2) and the air exhauster (4) is dismountable.
Further, the cotton holder of activated filter film (3) is fixed through bolt respectively respectively and between dust return duct (2) and the air exhauster (4).
Further, dust return air inlet (1) is the cover body structure, and the under shed of this cover body structure is greater than the bore area of upper shed.
Further, switch (8) is arranged on the dust return air inlet (1).
Further, on dust return air inlet (1), also be provided with bulb (7).
This list station dust exhausting equipment that is welded is compared with existing conventional single station CO2 cleaner, has following beneficial effect:
(1) the single station of the present invention is welded, and dust exhausting equipment makes cleaner and the anchor clamps that freeze effectively combine, and greatly reduces manufacturing cost, saves the space, has improved employee's operating environment simultaneously.
(2) the present invention makes the dust return air inlet can rotate freely angle owing to adopt the structure of dust return duct and bourdon tube one, makes things convenient for the employee to operate, and can guarantee that the dust return air inlet keeps stable attitude simultaneously, avoids because deadweight is sagging.
(3) the cotton holder of activated filter film of the present invention is dismountable; Can easily change, guarantee dust removing effects, guarantee the cleaning and the machine shaft cleaning on draught fan impeller surface; Avoid influencing dust removing effects because dust too much causes influencing the vane machine machine shaft and can not run well.
Description of drawings
Fig. 1: the be welded structural representation of dust exhausting equipment of the single station of the present invention.
Description of reference numerals:
1-dust return air inlet; 2-dust return duct; The cotton holder of 3-activated filter film; 4-air exhauster; 5-weld jig basal plane; 6-workpiece; 7-bulb; 8-switch; 9-bourdon tube; 10-fastening bolt.
The specific embodiment
Below in conjunction with Fig. 1, the present invention is further specified:
The anti-dress of air exhauster 4 impellers is guaranteed that the air exhauster wind direction is reverse exhausting, then air exhauster 4 is fixed on the weld jig basal plane 5 through fastening bolt 10,, this air exhauster 4 is installed toward a side for guaranteeing also to adorn effective welding procedure space.
Bourdon tube 9 connects into an integral body with dust return duct 2, is convenient to dust return air inlet 1 and can rotates freely angle, makes things convenient for the employee to operate.Can guarantee simultaneously that dust return air inlet 1 keeps stable attitude, avoids because deadweight is sagging.
The cotton holder 3 of activated filter film is carried out Corner Strapped through bolt to be connected on air exhauster 4 return air inlets own; Dust return duct 2 is carried out Corner Strapped on the cotton holder 3 of activated filter film through bolt equally; Dust return air inlet 1 is carried out Corner Strapped on dust return duct 2 through bolt equally; Switch 8 is fixed on dust return air inlet 1 outer cover with bulb 7; After being placed into workpiece above the anchor clamps like this, adjust dust return duct 2 positions with over against welding work pieces through bourdon tube 9, starting switch 8 such as makes at brand 7 and air exhauster 4 energising power supplys synchronously simultaneously, and whole work just can begin.
The replacing of the cotton holder 3 of activated filter film combines the workload of actual welding to confirm; Next order of classes or grades at school of ordinary circumstance is once cleared up; Mainly the activated filter film cotton is taken out cleaning from holder, air exhauster 4 needs time-based maintenance simultaneously, guarantees the cleaning and the machine shaft cleaning on draught fan impeller surface; Avoid influencing dust removing effects because dust too much causes influencing the vane machine machine shaft and can not run well.
The be welded installation steps of dust exhausting equipment of the single station of the present invention are following:
