Oil-quenching-tank flue-gas collecting device

Abstract

The present invention relates to a heat treatment fume collection device, in particular to a quenching oil tank fume collection device, which includes at least two covers, wherein: the covers are both half-shell structures, and are all covered above the quenching oil tank; At least one of the at least two hoods is a rotating hood that can rotate above the quenching oil tank; at least two hoods can form a closed shell or form a quenching chamber for workpieces to enter and exit through the rotation of the rotating hood. The inlet and outlet of the oil tank. The fume collection device of the quenching oil tank of the present invention can realize the 360° omni-directional entry and exit of the workpiece into and out of the quenching oil tank, the limitation of the operating space is smaller, and the operation is more convenient; Smaller footprint and lower acquisition cost.

Description

technical field [0001] The invention relates to a heat treatment fume collection device, in particular to a quenching oil tank fume collection device. Background technique [0002] When the workpiece is quenched in the oil tank, it will generally cause a short-term fire on the surface of the oil tank and produce a lot of oily smoke, which makes the production unsafe. Traditional quenching oil tanks are generally open, and there is no equipment for effective collection and treatment of flue gas, which makes a large amount of oil vapor and quenching flue gas diffuse in the workshop, polluting the environment and damaging health. With the continuous promulgation of new national environmental protection regulations, quenching oil fumes cannot be discharged in an organized manner, and factories require smoke-free production. Subsequently, various fume collecting hoods for collecting fume have been born one after another. [0003] Existing fume collecting hoods are usually of fix...

AI Technical Summary

Problems solved by technology

[0003] Existing fume collecting hoods are usually of fixed structure or mobile structure, but there are certain defects, for example: the fixed structure fume collecting hood occupies a large space, the workpiece can only enter and exit from one or several directions, and the operating space is limited The mobility is too large; the mobile smoke hood needs a dedicated quenching lifting mechanism, which also occupies a large space, and cannot be completely sealed, and the smoke leakage is serious
