Abstract

The utility model discloses a welding-cinder eliminating device for submerged-arc welding in the inside of a double face spiral joint submerged-arc welding steel pipes, which is composed of a suction mouth, a casing pipe, a cyclone separator, an exhaust blower and a high tension electrostatic dust remover. The utility model is an environmental protection equipment to prevent dust polluting atmosphere, has the advantages of less noise, simple structure and safety, and can ease workers labour intensity.

Description

Welding-cinder eliminating device

A kind of two-sided spiral meets the inboard submerged-arc welding welding slag of submerged-arc welding steel pipe scavenge unit, its architectural feature is by the suction nozzle 1, transmission mechanism 2, motor 3, sleeve pipe 4, the bearing 5 that suck welding slag, removes the cyclone separator 6,7 of coarse grain welding slag, produce negative pressure air exhauster 8, the high-voltage electrostatic dust separator 9 of removing dust, the suction line 10 that can move freely, Live roller 11, steel pipe (workpiece) 12, flash composition such as valve 13.

Each petroleum steel pipe factory of the whole nation adopts crane to sling steel pipe with the welding slag in it, solder flux is poured out, perhaps use pneumatic, the lever that surges tilts steel pipe and pours out more than 45 degree, and is so both dangerous, easy again damage equipment, dust is flown upward all over the sky, caused than serious environmental and polluted, working strength of workers is big simultaneously, has influenced the healthy of workman.

The purpose of this utility model has been to avoid above-mentioned shortcoming, and in the service life of extension device, environmental contamination reduction has alleviated workman's labour intensity, reaches a kind of welding slag of carrying out production strictly in line with rules and regulations and designing and removes device.

The purpose of this utility model can reach by following measure: can before and after the suction nozzle 1 that moves freely welding slag in the steel pipe 12 and solder flux are sucked, through movably suction line 10 and sleeve pipe 4, reach cyclone separator 6 and 7 and carry out cyclonic separation, welding slag is separated with the bigger solder flux of granularity, and the less dust of granularity is separated in high-voltage electrostatic dust separator 9; The equipment that produces negative pressure is except that with the air exhauster, vacuum available pump also, with swiftly flowing water generates means for applying negative and other method that can produce negative pressure all can, require and discharge the amount of air according to different negative pressure, can adopt different equipment and method.

The drawing explanation of accompanying drawing: Fig. 1 is a front view, and Fig. 2 is a vertical view.

The utility model will be described in further detail in conjunction with the accompanying drawings, when air exhauster 8 exhausting, by suction nozzle 1 movably steel pipe (workpiece) 12 through movably suction line 10 and sleeve pipe 4, entering cyclone separator 6 separates with 7, suction nozzle 1 front and back move freely, suction line 10 places sleeve pipe 4, sleeve pipe is fixed on the bearing 5, when welding slag or solder flux dust reach a certain height, flashing valve (there have typing to produce to be brilliant) 13 opens automatically, welding slag or solder flux are discharged, the grey dust and the air that do not eliminate enter in the high-voltage electrostatic dust separator 9, and air is got rid of from the top, and ash fall is in the bottom, when dust reach a certain height, flash valve 13 and open discharge dust automatically.

It is little that the utility model compared with prior art has a noise, and the no dust pollution atmosphere is simple in structure, safe and reliable, implements easily, alleviated workman's labour intensity, do not affect the healthy of workman.

Claims
