Embodiment Construction
[0024] Below in conjunction with accompanying drawing and specific embodiment the present invention will be further described:
[0025] Such as figure 1 , figure 2 and image 3 As shown, the automatically controlled safety explosion-proof muffle furnace includes a bracket 1, a furnace body 2, an automatic feeding mechanism and a control device. A hydrogen outlet pipe 4 is provided, a feed door 5 is provided on one side of the furnace body 2, and a discharge door 6 is provided on the other side, a feed passage 7 is provided between the feed door 5 and the furnace body 2, and a discharge door 6 There is a discharge channel 8 between the furnace body 2 and a molybdenum boat for placing materials in the furnace body 2. The automatic feeding mechanism is connected with the molybdenum boat and can push the molybdenum boat to move. The control device is electrically connected to the automatic feeding mechanism. connected, the control device includes a control circuit board and a ...

The invention relates to an automatic control safety explosion-proof muffle furnace. The automatic control safety explosion-proof muffle furnace comprises a support, a furnace body, an automatic feeding mechanism and a control device. The furnace body is internally provided with a molybdenum boat for bearing materials. The control device comprises a control circuit board and an optoelectronic switch. A bottom plate of a feeding port of the furnace body is provided with a hydrogen air curtain groove, the air curtain groove communicates with an air inlet pipe, and a feeding channel is provided with an explosion-proof device. According to the automatic control safety explosion-proof muffle furnace, a PLC and an optoelectronic switch are used for controlling starting and stopping actions of the whole boat feeding process of the muffle furnace, and continuous sintering processing of a tungsten-molybdenum alloy is achieved. According to the automatic control safety explosion-proof muffle furnace, the feeding port of the furnace body is provided with a hydrogen air curtain isolating device preventing air from entering, air is effectively prevented from entering the muffle furnace to be mixed with hydrogen, meanwhile, the feeding channel is provided with the explosion-proof device, the hurting phenomenon of blasting of a traditional muffle furnace is effectively avoided, and the safetyof the tungsten-molybdenum furnace is further improved. The automatic control safety explosion-proof muffle furnace is high in degree of automation, the labor intensity is reduced, the working efficiency is improved, using is safe and reliable, and the working environment is better.
Description
technical field [0001] The invention relates to the technical field of muffle furnaces, in particular to an automatic control safety explosion-proof muffle furnace which is used for the production of tungsten-molybdenum alloy and adopts a photoelectric switch and an explosion-proof device. 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 and close the door for feeding or discharging, which cannot be used for continuous pro...
