Quenching furnace with impurity removal function

Abstract

The invention relates to a quenching furnace with an impurity removal function. The quenching furnace comprises a main body, a cover plate, a heating chamber, a lifting plate, a quenching chamber, twoair cylinders, a stirring mechanism and an impurity removal mechanism, wherein the impurity removal mechanism comprises a filter screen, a transmission assembly, two driving assemblies and two impurity removal assemblies; each impurity removing assembly comprises a circular ring, a collecting box, a connecting pipe, a first branch pipe, a second branch pipe, a piston, a spring, a fixing ring, a first bearing, two fixing rods and a plurality of suction nozzles; each driving assembly comprises a transmission shaft, a one-way bearing, a driving shaft, a driving disc, a driving rope and two second bearings; and the stirring mechanism comprises a motor, a stirring shaft, a transmission gear, a third bearing and a plurality of stirring plates. According to the quenching furnace with the impurity removal function, the impurity removal function on quenching liquid is achieved through the impurity removal mechanism, the situation that impurities in the quenching liquid influence the quenchingquality is avoided, and the stirring function on the quenching liquid is achieved through the stirring mechanism, so that a workpiece makes full contact with the quenching liquid, and accordingly thequenching efficiency is improved.

Description

technical field [0001] The invention relates to the field of heat treatment, in particular to a quenching furnace with the function of removing impurities. Background technique [0002] The quenching furnace is a furnace that heats the workpiece before quenching. Quenching is to put the workpiece into the furnace and heat it to the quenching temperature above the critical point and keep it for a period of time, then quickly take the workpiece out of the furnace and put it into the quenching liquid (oil or water) for quenching. The heat source of the furnace can be electricity and fuel, and the temperature can be measured by a thermocouple. Furnaces using electricity, gas, and liquid fuels can be automatically controlled and regulated by instruments. [0003] When the existing quenching furnace is performing quenching work, because the workpiece is placed in the quenching liquid, the temperature is relatively concentrated, which reduces the conduction efficiency, thereby af...

Problems solved by technology

[0003] When the existing quenching furnace is performing quenching work, because the workpiece is placed in the quenching liquid, the temperature is relatively concentrated, which reduces the conduction efficiency, thereby affecting the quenching efficiency. Not only that, but the existing quenching furnace is quenched after long-term quenching. There will be more impurities in the liquid, which will affect the quality of the quenching liquid, affect the quenching work, reduce the quality of quenching, and greatly reduce the reliability of the existing quenching furnace
