Abstract

The invention provides a quenching gas recycling system, which comprises a nitrogen cylinder, a gas storage tank 1, a gas storage tank 2, a quenching work chamber, a filter, a cooler, an air compressor, a gas pipe, a ball valve, a pressure regulating valve, a safety valve, a check valve, a drainage valve and the like. The system fundamentally solves the problem of large gas consumption in the gasquenching process, and improves resource utilization, reduces environmental pollution index, reduces cost, and meets automatic control requirements by recycling waste gas. The quenching gas recyclingsystem and the quenching work chamber are rigorously designed, and can quickly and efficiently complete gas quenching and nitrogen recycling work.

Description

technical field [0001] The invention relates to a quenching gas recycling system, belonging to the technical field of resource recycling. Background technique [0002] At present, none of the known gas quenching systems is equipped with nitrogen circulation equipment, and a large amount of nitrogen is discharged after one use, which not only causes a waste of resources, but also increases the cost of quenching. Therefore, it is necessary to improve the prior art. Contents of the invention [0003] The purpose of the present invention is to provide a quenching gas recycling system, which solves the problem of huge nitrogen consumption in the gas quenching process, increases the utilization rate of resources while ensuring the quenching quality of parts, and can reuse nitrogen for quenching operations, thereby The utilization rate of nitrogen gas is improved, and the cost of gas quenching is reduced. [0004] The technical solution adopted by the present invention to solve...
