Fire extinguishing and smoke dust collecting device

Abstract

The invention discloses a fire extinguishing and smoke dust collecting device comprising a telescopic section, a top cover, a grabbing device and a dust purifying device. A telescopic section is arranged on the lower surface of the top cover, is of a cylindrical structure and is coaxial with the top cover; the grabbing device is arranged on the top cover, and the grabbing end of the grabbing device is located in the telescopic section; and the top of a pit furnace quenching oil tank is connected with the dust purifying device. The device can effectively extinguish fire and collect smoke dust waste gas generated during quenching, the purpose of safe production is achieved, the collected smoke dust waste gas can be further purified subsequently, and the workshop environment is improved.

Description

technical field [0001] The invention belongs to the technical field of fire extinguishing and dust collection in a quenching oil tank of a well type furnace, and in particular relates to a fire extinguishing and dust collection device. Background technique [0002] The oil quenching process of the heat treatment pit furnace is to heat the workpiece stack in the pit furnace, and then use the crane hook (or clamping pliers) in the workshop to lift the hot workpiece stack out of the pit furnace and move it Go to the top of the quenching oil tank, and then the hook (or clamp) of the crane will lower the workpiece stack into the quenching oil tank for quenching. During the process of sinking the hot workpiece into the quenching oil, a large amount of flames and smoke and exhaust gas will be generated, which will seriously pollute the workshop environment, affect the health of the operators, and there is also a risk of fire. [0003] In the situation of increasingly stringent saf...

Problems solved by technology

Of course, this solution also requires an independent and dedicated double-girder crane. In order to prevent the workpiece stacks hanging in the fume collecting hood from swinging due to inertia when moving, the control system is also more particular, so the cost is expensive.

[0006] However, there are still many well-type furnaces in the heat treatment industry in our country. The safety problems (oil tank fire) and environmental protection problems (release of a large amount of smoke and waste gas) during quenching need to be solved urgently, and economical, efficient and simple solutions are urgently needed.
