The internal layer of described burner hearth is built into by hollow ball alumina brick, and the top of burner hearth is high-strength high temperature-resistant ceramic beaverboard, and the outer layer of burner hearth is the most successively with high-temperature ceramic fibre and low-temp ceramics fiber composition.
Described bell hydraulic lifting and translation system include hydraulic cylinder, lifting arm, hoist cable, rotating support and rotary support, and bell hydraulic lifting and translation system are for controlling the folding of bell.
The lifting of described furnace bottom includes motor, elevator, shaft coupling, the axis of guide, elevating screw, furnace bottom cover, lifting pedestal, shears, roller and roller track with translation system.
Described cold terminated line room is arranged on the sidewall of body of heater, and cold terminated line room is connected with the external world.
Described cold terminated line room is arranged on the top of body of heater, and cold terminated line room is the chamber body closed, and cold terminated line room is by the air pressure in its independent air-channel system conditioning chamber.
Beneficial effect
The sintering furnace of the present invention it can be avoided that under high temperature hyperbaric environment heater cold junction temperature too high and cause the wiring position generation wire clamp of the cold end of heater to melt, beat the phenomenons such as arc, short circuit, oxidation and heater cold end fracture and have that burner hearth is lightweight, high insulating effect, advantage simple to operate, easy to maintenance.
