Description

Technical Field

[0001] The utility model relates to the technical field of roasting furnaces, in particular to a roasting furnace which is convenient to clean. Background Art

[0002] A roasting furnace is a high-temperature processing equipment, also known as a calcining furnace. According to the different energy sources used, it can be divided into four types: coal-fired furnaces, gas-fired furnaces, oil-fired furnaces and electric heating furnaces; according to the heating method, it can be divided into two categories: direct heating and indirect heating; according to the operation method, it can be divided into two types: continuous operation and intermittent operation. Roasting furnaces are widely used in the production process of special materials in industries such as petrochemicals, inorganic chemicals, and metallurgy. When the roasting furnace is in use, smoke will be discharged through the flue, and the flue needs to be cleaned regularly to keep it clean. For the convenience of cleaning, the existing roasting furnace flue generally has a cleaning pipe installed on the side, but the smoke will enter the cleaning pipe and flow, affecting the circulation speed. After long-term use, a lot of dust will accumulate inside the cleaning pipe, increasing the dust cleaning area and increasing the workload.

[0003] China Utility Model Announcement No.: CN212901569U includes a roasting furnace flue main body, a cleaning pipe is installed on the outside of the top of the roasting furnace flue main body, and a sealing top cover is connected to the outside of the top of the cleaning pipe, the sealing top cover and the two sides of the outer wall of the cleaning pipe are respectively connected with hydraulic hinges and sealing lock buckles, the two sides of the top of the sealing top cover are provided with avoidance through holes, and the avoidance through holes are connected with a telescopic push rod body, the top of the cleaning pipe is installed with a supporting column, and the top of the supporting column is connected with a fixed table, the two sides of the top of the fixed table are installed with electric push rod hosts, and the bottom of the electric push rod host is externally connected with a telescopic push rod body. The roasting furnace flue structure that is easy to clean regularly can effectively reduce the smoke from entering the cleaning pipe, avoid the situation that the cleaning pipe affects the smoke circulation and the dust accumulates on the inner wall, and facilitates subsequent cleaning.

[0004] The applicant found that this patent had some shortcomings in use: when cleaning the flue of the roasting furnace, the guide baffle needs to be raised first through the electric push rod, and after leaving the cleaning pipe, the sealing top cover needs to be rotated to open the cleaning pipe for cleaning. However, due to the high height of the electric push rod, the overall space occupied is large, which is not space-saving enough.

[0005] Therefore, the utility model designs a roasting furnace which is convenient to clean to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of the utility model is to provide a roasting furnace which is easy to clean, so as to solve the problems raised in the above background technology.

[0010] Preferably, the driving mechanism includes a rotating shaft, which is rotatably mounted on the top of the U-shaped frame, a driving gear is mounted on the bottom of the rotating shaft, and a driven gear meshing with the driving gear is mounted on one side of the screw rod. The rotating shaft causes the driving gear to rotate, and the driving gear drives the two driven gears to rotate, so that the two screw rods can rotate synchronously, which is more convenient.

[0011] Preferably, a rotating wheel is installed on the top of the rotating shaft, and the rotation of the wheel makes it convenient for the staff to rotate the rotating shaft and to lift the pipe cover upwards.
