Oil-quenching-tank flue-gas collecting device

Abstract

The invention relates to a heat-treatment flue-gas collecting device, in particular to an oil-quenching-tank flue-gas collecting device. The oil-quenching-tank flue-gas collecting device comprises atleast two cover bodies, wherein the cover bodies are of semi-shell structures, and cover the upper portion of an oil quenching tank; at least one cover body in the at least two cover bodies is a rotating cover body, and the rotating cover body can rotate at the upper portion of the oil quenching tank; the at least two cover bodies can form a closed shell through rotating of the rotating cover body, or form an in-out opening for a workpiece to pass in and out the oil quenching tank. By means of the oil-quenching-tank flue-gas collecting device, it can be achieved that the workpiece passes in and out the oil quenching tank all around, the limitation performance of operation space is smaller, and operation is more convenient; in addition, the oil-quenching-tank flue-gas collecting device is ingenious and simple in structural design, smaller in device occupied space and lower in 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
