[0002] The heat treatment mesh belt furnace is a device widely used in industrial production. Its mesh belt furnace is one of the commonly used devices in the metal heat treatment process. After the metal is heat-treated, its physical properties can be changed, such as strength, hardness, toughness, wear resistance, etc. The mesh belt furnace can perform various types of heat treatment on metals, such as annealing, normalizing, quenching, tempering, surface carburizing, nitriding, etc.

[0003] In the existing technology, the device transports the workpiece to the conveyor through the loading hoist, and then transports it to the water tank by the conveyor, and raises the temperature to fifty degrees Celsius to form warm water cleaning, so that the lubricating oil on the workpiece is thoroughly cleaned. Subsequently, a series of processing procedures for the workpiece are completed through multiple processes such as a quenching heating furnace, a quenching tank, a tempering furnace, and a blackening tank. However, in the actual use process, the device only cleans the surface of the workpiece with warm water, resulting in the warm water being unable to completely remove the lubricating oil attached to the surface. Especially when the lubricating oil has penetrated into the tiny gaps on the material surface or formed stubborn stains, the surface of the workpiece is not thoroughly cleaned. Therefore, a heat treatment mesh belt furnace needs to be improved. Content of the Utility Model
