Melting furnace for metal processing

Abstract

The invention provides a metal processing melting furnace which comprises a furnace body, the inner side of the furnace body is hollow, a storage plate with meshes is transversely arranged at the hollow position of the furnace body, a carbon frame which is used for bearing coal and is provided with a mesh structure is arranged on the lower side of the storage plate, and a water tank for absorbing combustion waste heat is embedded in the position, corresponding to the carbon frame, in the furnace body structure. The top of the water tank is provided with a driving mechanism driven by steam pressure of the water tank, the driving mechanism is in transmission connection with a shifting frame arranged on the lower side of the carbon frame, and one side of the driving mechanism is provided with a pressure storage mechanism for controlling the movement frequency of the shifting frame. The stirring frame is driven to stir and crush coal on the carbon frame, carbon residues are discharged, the combustion rate of the coal is increased, the utilization rate of energy is further increased, the content of CO generated by incomplete combustion in tail gas is reduced, the tail gas treatment difficulty and consumption are reduced, the energy utilization rate is increased, and good development prospects are achieved.

Description

technical field [0001] The invention relates to the field of chemical metallurgy, in particular to a melting furnace for metal processing. Background technique [0002] In the traditional chemical and metallurgical field, in order to obtain raw materials that meet the requirements, it is often necessary to melt solid raw materials in a high-temperature furnace. The heat sources of the furnace are mainly oil injection, high-voltage current and coal. Low is widely adopted. [0003] However, the traditional coal-type furnace is affected by surface hardening caused by coal combustion or residual coal slag after combustion, and the contact between the remaining coal and oxygen in the air is reduced, which will lead to incomplete combustion of coal, which will not only lead to waste of fuel utilization, but also It will also produce more coal ash. The coal ash attached to the furnace or exhaust pipe will have corresponding adverse effects. Incomplete combustion will also generate...

[0003] However, the traditional coal-type furnace is affected by the surface hardening caused by coal combustion or the residual cinder after combustion, and the contact between the remaining coal and oxygen in the air is reduced, which will lead to incomplete combustion of coal, which will not only lead to waste of fuel utilization, It will also produce more coal ash, which will have a corresponding adverse effect if the coal ash adheres to the furnace or exhaust pipe. Incomplete combustion will also produce a large amount of CO, which increases the difficulty and cost of tail gas treatment, and also makes the tail gas pollute the environment. more serious
