Mesh belt furnace rapid carbon burning system

Abstract

The invention provides a mesh belt furnace rapid carbon burning system and relates to the field of industrial heat treatment equipment. The mesh belt furnace rapid carbon burning system comprises a mesh belt furnace, a gas replacement device, a carbon burning device and a control device. The gas replacement device comprises an inert gas source, a spray pressing pump, a purging pipeline and a first flow adjusting assembly. The inert gas source is connected with the mesh belt furnace through the purging pipeline. The spray pressing pump is arranged in the position, between the inert gas source and the mesh belt furnace, of the purging pipeline. The first flow adjusting assembly is arranged in the position, between the spray pressing pump and the mesh belt furnace, of the purging pipeline. The carbon burning device is connected to the mesh belt furnace. The control device is electrically connected with the spray pressing pump, the first flow adjusting assembly and the carbon burning device. According to the mesh belt furnace rapid carbon burning system provided by the invention, compared with the prior art, inert gas is introduced before carbon burning, thus, an explosion whistle cannot occur when air is introduced through the carbon burning device, and meanwhile, deposited carbon in the mesh belt furnace can be effectively and rapidly removed by the carbon burning air introduced through the carbon burning device.

Description

technical field [0001] The invention relates to the field of industrial heat treatment equipment, in particular to a rapid carbon burning system of a mesh belt furnace. Background technique [0002] After more than half a century of development, the mesh belt furnace has reformed and developed several generations of products, from the first generation of heating under an oxidizing atmosphere to the second generation of protective atmosphere, less oxidation-free heating, and to the third generation of controllable Atmosphere heating, fourth generation through computer management, etc. [0003] As we all know, after the continuous use of the mesh belt furnace, due to the protective atmosphere in the furnace, carbon black may be produced in the furnace, scattered or attached to the metal components in the furnace, the outer wall of the radiant tube, the workpiece and the surface of the mesh belt. At this time, it is often necessary to burn charcoal in the hearth, but the inven...

AI Technical Summary

Problems solved by technology

At this time, it is often necessary to burn charcoal in the hearth, but the inventors found that the charcoal burning in the hearth in the prior art is often not thorough, and the incomplete charcoal burning in the hearth will cause the following hazards:

[0004] 1. The oxygen probe cannot accurately measure the carbon potential in the furnace, which affects the quality of heat treatment, causes accelerated carbon deposition, and damages the oxygen probe and the metal components in the furnace

[0005] 2. Too much carbon deposit, carbon black covers the outer wall of the radiant tube, so that the heat cannot be dissipated, causing damage to the protective tube and heating element

[0006] 3. The temperature measurement of the thermocouple is inaccurate due to carbon deposition, making the actual temperature in the furnace higher than the set temperature, which affects the quality of heat treatment

[0007] 4. The stirring fan has too much carbon deposit, which affects the dynamic balance and causes abnormal shaking. In severe cases, the fan bearing will be deformed and stuck, and even the stirring motor will be burned out.

[0008] 5. Carbon deposits will also cause the metal rollers in the furnace to be stuck or deformed, and in severe cases, the rollers will break

[0009] 6. Excessive carbon deposits will fall into the oil tank with the operation of the mesh belt, resulting in accelerated aging of the quenching oil

[0010] At the same time, in the existing furnace carbon burning technology, the carbon burning speed is slow, which makes the production efficiency low
