Description

Fire channel cover of roasting furnace Technical Field The utility model relates to the technical field of roasting furnaces, in particular to a fire channel cover of a roasting furnace. Background The roasting furnace is one of the main thermal equipment in the carbon production industry, has higher energy consumption and lower heat utilization rate, is generally built underground, only the flame path cover is exposed on the ground, and consists of a steel structure framework and refractory materials. When the roasting furnace is used for production, the inner production condition of the roasting furnace is often observed by lifting the roasting furnace, so that the fire hole is always in an open state, a large amount of heat is easily discharged from the fire hole, the energy loss during firing of the carbon roasting furnace is increased, and the fuel consumption of the roasting furnace is improved, and therefore, the fire channel cover of the roasting furnace is provided for solving the problems. Disclosure of utility model In order to overcome the deficiencies of the prior art, at least one technical problem presented in the background art is solved. The fire channel cover of the roasting furnace comprises a fire channel cover body, wherein the inner side of the fire channel cover body is connected with a sealing block in a sliding manner, the outer side of the sealing block and the outer side of the fire channel cover body are fixedly connected with connecting blocks, the inner sides of the connecting blocks are connected with connecting rods in a sliding manner, the outer sides of the sealing blocks are fixedly connected with lifting frames, one side of each lifting frame is connected with a first limiting rod in a sliding manner, the inner sides of the lifting frames on the other side are connected with a first screw rod in a threaded manner, the first screw rod is connected with the fire channel cover body in a rotating manner, the outer sides of the fire channel cover body are connected with a second screw rod in a rotating manner, gears are fixedly connected with the outer sides of the first screw rod and the second screw rod, the gears are meshed with each other, the outer sides of the second screw rod are connected with high-temperature-resistant glass in a sliding manner, and the inner sides of the high-temperature-resistant glass are connected with a second limiting rod in a sliding manner; the step comprises covering the fire path cover body and the sealing block on the fire port for heat preservation, pulling the connecting rod to separate from the connecting block when observing the production condition of the inner side of the roasting furnace, driving the gears on the outer side of the connecting block to rotate through the first screw, and mutually meshing the gears to enable the second screw to rotate in opposite directions, wherein the first screw drives the sealing block to lift up to the fire path cover body so as to facilitate the observation of a user, the second screw drives the high temperature resistant glass to move downwards, the high temperature resistant glass shields the gap between the lifted sealing block and the fire path cover body to reduce the heat loss during the observation, observing through the high temperature resistant glass, and lifting the high temperature resistant glass away from the fire path cover body after the observation, the device is not easy to be baked at high temperature all the time, the sealing block is moved downwards to return to the position for continuous sealing, and the practicability of the device is improved.
