Blowout prevention device for shielding screen at furnace outlet

Abstract

The invention provides a furnace outlet blocking screen material spraying prevention device which comprises a calcium carbide furnace main body, a raw material ejection opening, a furnace outlet trolley and a blocking screen plate, the raw material ejection opening is fixedly connected to the calcium carbide furnace main body, the furnace outlet trolley is located under the raw material ejection opening, and the blocking screen plate is arranged on the side, away from the calcium carbide furnace main body, of the raw material ejection opening. The calcium carbide furnace main body is fixedly connected with an anti-sputtering cap; the raw material spraying device has the beneficial effects that when the raw material spraying opening is used for discharging materials, firstly, the anti-sputtering cover cap plays an anti-sputtering effect on the raw materials, the slag material conduction blade assists in preventing sputtering spraying, and then the shielding plate and the material guide plate on the shielding plate are used for further preventing sputtering of the raw materials, so that the raw materials are not prone to sputtering in the discharging process of the device, and the discharging efficiency is improved. And meanwhile, the raw materials and the calcium carbide can smoothly flow into the pot vehicle during material spraying, so that the labor intensity of workers during hot calcium carbide cleaning is reduced, and the sanitation and tidiness of the field environment are guaranteed.

Description

technical field [0001] The invention relates to the technical field of calcium carbide furnace production, in particular to an anti-blowout device for a screen at the outlet of a furnace. Background technique [0002] Calcium carbide furnace is the main equipment for the production of calcium carbide; in the calcium carbide furnace, due to the high temperature emitted by the arc, the furnace material is melted and reacted to form calcium carbide; because the reaction temperature is as high as 2000 ° C, such a high temperature is difficult for general refractory materials; so the furnace body The volume of the furnace must be greater than the reaction space; that is to say, a layer of charge should be reserved between the reaction zone and the furnace lining to protect the furnace lining. [0003] The calcium carbide furnace is occasionally accompanied by raw material ejection during the furnace, and it is easy to spray on the screen and scatter into the track, causing the ca...
