Problems solved by technology

However, when the above two muffle furnaces are charging or discharging, when the door is opened and closed, a small amount of air outside the furnace enters the furnace and mixes with hydrogen, which may cause "blasting" phenomenon, sometimes even due to " "fire" and hurt people
Therefore, there are certain potential safety hazards in the production process of the existing muffle furnace

Abstract

The invention relates to an explosion-proof device of a muffle furnace. The explosion-proof device of the muffle furnace comprises a furnace body and a support. One end of the furnace body is providedwith a hydrogen inlet pipe, and the other end of the furnace body is provided with a hydrogen outlet pipe. The hydrogen inlet pipe is arranged on a shell of a discharging channel, and the hydrogen outlet pipe is arranged on a shell of a feeding channel. The part, between the hydrogen outlet pipe and the furnace body, of the shell of the feeding channel is provided with an explosion-proof device body. The hydrogen inlet pipe, the hydrogen outlet pipe and the explosion-proof device communicate with a furnace cavity in the furnace body. The explosion-proof device body comprises an explosion-proof pipe, an explosion-proof membrane, an upper flange and a lower flange. The lower flange is fixed to the upper end of the explosion-proof pipe, the lower end of the explosion-proof pipe is fixed to the shell of the feeding channel, and the explosion-proof membrane is arranged between the upper flange and the lower flange. The upper flange, the explosion-proof membrane and the lower flange are fixed through bolts to form seal connection. According to the explosion-proof device of the muffle furnace, the part, between the hydrogen outlet pipe and the furnace body, of the shell of the feeding channel is provided with the explosion-proof device, so that the safety of the muffle furnace is improved. The explosion-proof device of the muffle furnace is simple in structure and safety and reliablein use.

Description

technical field [0001] The invention relates to the technical field of muffle furnaces, in particular to an explosion-proof device for muffle furnaces used for processing sintered tungsten-molybdenum alloys. Background technique [0002] Both non-ferrous metals tungsten and molybdenum are refractory metals. The production of existing tungsten-molybdenum alloys is generally processed by powder metallurgy sintering. The production process is usually to put the molybdenum boat loaded with materials into the muffle furnace for high-temperature sintering. Hydrogen is used as a protective gas during the sintering process. [0003] At present, traditional muffle furnaces for processing tungsten-molybdenum alloys generally have two structures: single-door and double-door. The single-door muffle furnace needs to open the door for feeding or discharging, which cannot be used for continuous production. The degree of automation is low and it is not suitable for batch production. Produc...
