Continuous sealed high-temperature mesh belt furnace

Abstract

The invention discloses a continuous sealed high-temperature mesh belt furnace. The continuous sealed high-temperature mesh belt furnace comprises a furnace body and a rack, the continuous sealed high-temperature mesh belt furnace further comprises a feeding propulsion mechanism, a double-door front discharging replacement chamber, a sealed mesh belt driving chamber arranged at the front end of the furnace body, and the continuous sealed high-temperature mesh belt furnace further comprises a furnace body water cooling section, a sealed mesh belt rotating chamber, a sealed discharging driving roller set, a double-door rear discharging replacement chamber, a material moving mechanism and a material circulating conveying mechanism arranged at the rear end of the furnace body. According to themesh belt furnace, all the parts are connected in a sealed mode, especially the parts connected with the front portion and the rear portion of the furnace body in a sealed mode, sealing of the mesh belt furnace is achieved, and compared with an open-type mesh belt furnace, the gas consumption can be reduced, and the atmosphere using cost is saved.

Description

technical field [0001] The invention relates to a mesh belt furnace, in particular to a continuous sealed high-temperature mesh belt furnace, which belongs to the technical field of high temperature furnaces. Background technique [0002] The mesh belt furnace is a furnace body that uses a mechanically driven intermittent or continuously advancing mesh belt to pass the workpiece through a temperature-controlled heating zone, and then meets the requirements of the heat treatment process. Although the conventional mesh belt furnace has a high production capacity, the conventional mesh belt furnace has an open structure, and the use of micro positive pressure to block the entry of external air, or the curtain structure cannot realize the sealing of the furnace body, and the gas consumption is large, and the atmosphere The use cost is high; and the high-temperature process cannot be used. The reason is that the conventional mesh belt furnace uses a mesh belt made of stainless st...

Problems solved by technology

Although the conventional mesh belt furnace has a high production capacity, the conventional mesh belt furnace has an open structure, and the use of micro positive pressure to block the entry of external air, or the curtain structure cannot realize the sealing of the furnace body, and the gas consumption is large, and the atmosphere The use cost is high; and the high-temperature process cannot be used. The reason is that the conventional mesh belt furnace uses a mesh belt made of stainless steel for material transportation, and stainless steel is prone to deformation and softening when it is greater than 1150 ° C, and cannot be used normally; The mesh belt furnace feeds at the front end and discharges at the rear end, and runs the material tray back and forth, which is labor-intensive
