A mechanism for lifting and lowering the dust-absorbing furnace cover and an industrial furnace using the mechanism

Abstract

The invention relates to a dust collection furnace lid mechanism capable of ascending and descending. An industrial furnace comprises a furnace body, a furnace lid and a lifting mechanism used for lifting and dropping the furnace lid. A semi-closed cavity is formed by the inner wall of the furnace lid. A salting channel communicating with the cavity is formed in the top of the furnace lid. The dust collection furnace lid mechanism further comprises a fixed flue gas pipeline and a movable flue gas pipeline of which one end communicates with the salting channel in a fixed mode. The fixed flue gas pipeline is provided with a first flue gas inlet, a second flue gas inlet and a flue gas outlet, and the first flue gas inlet, the second flue gas inlet and the flue gas outlet communicate with the interior of the fixed flue gas pipeline. The flue gas outlet is connected with a flue gas exhauster. The end of the movable flue gas pipeline can move up and down along the outer wall of the fixed flue gas pipeline. The salting channel communicates with the first flue gas inlet or the second flue gas inlet through the movable flue gas pipeline. According to the dust collection furnace lid mechanism, the condition that a material tool interferes with the furnace lid when workpieces are hoisted into the furnace body is avoided, and flue gas diffused in the furnace body can be exhausted and sucked in a centralized mode no matter when the furnace lid is opened or closed, so that the workshop environment is improved and the physical health of workers is facilitated.

Description

technical field [0001] The invention relates to a furnace cover, in particular to a liftable and dust-absorbing furnace cover mechanism. Background technique [0002] In the field of heat treatment technology, the collection and discharge of smoke and dust is one of the important links in the production process. Such as figure 1 As shown, the furnace cover 1' of the existing heat treatment furnace is arranged above the furnace mouth, and can be opened or closed by the lifting mechanism. A large amount of toxic gas such as smoke and dust will be directly diffused into the production workshop. Although a part of the toxic gas diffused into the workshop is finally discharged through the exhaust channel set on the top of the workshop, the circulation time of the toxic gas in the workshop is long, causing pollution. The production environment in the workshop is not conducive to the health of the production personnel. In addition, when the workpiece is hoisted in or out, the mat...

AI Technical Summary

Problems solved by technology

like figure 1 As shown, the furnace cover 1' of the existing heat treatment furnace is arranged above the furnace mouth, and can be opened or closed by the lifting mechanism. A large amount of toxic gas such as smoke and dust will be directly diffused into the production workshop. Although a part of the toxic gas diffused into the workshop is finally exhausted through the exhaust channel set on the top of the workshop, the circulation time of toxic gas in the workshop is long, causing pollution. The production environment in the workshop is not conducive to the health of the production personnel. In addition, when the workpiece is hoisted in or out, the material frame often interferes with the furnace cover and cannot be put in, which hinders the production progress and cannot be applied to heat treatment. In the production line, the scope of application is limited
