[0002] During the production process of alumina powder, an air lift is required to cooperate with the fresh chute of the purification system for transportation. The fresh chute is the main channel for alumina powder transportation. Impurities often exist in alumina powder, and these impurities are extremely likely to accumulate in the fresh chute, affecting the normal transportation of materials, resulting in uneven feeding of each air lift, and the inability of the materials to be evenly mixed with the fluorine-containing flue gas in the subsequent process for reaction. Eventually, the flue gas purification efficiency is reduced, and the stability of the produced materials is poor. Content of the Utility Model

[0003] According to the above deficiencies in the prior art, the technical problem to be solved by the utility model is: to provide an automatic cleaning device for impurities in a fresh chute, which can clean the accumulated impurities in the fresh chute, prevent the transportation of materials from being affected by the accumulation of impurities, enable the materials to be evenly mixed and react with the fluorine-containing flue gas, and improve the flue gas purification efficiency and the stability of the produced materials.

[0004] The automatic cleaning device for impurities in the fresh chute described in the utility model includes a fresh chute. The tail end of the fresh chute is connected to a blowing device, which can blow compressed air into the fresh chute. The head end of the fresh chute is connected to a discharging device. The discharging device includes a hopper and a discharging pipe. The hopper is funnel-shaped, the bottom of the hopper is connected to the discharging pipe, and a woven bag for receiving materials is tied to the bottom of the discharging pipe.

[0005] The technical solution of the utility model is to provide an automatic cleaning device for impurities in a fresh chute. When the impurities in the fresh chute need to be cleaned, the blowing device is turned on, and the impurities in the chute are blown towards the discharging device at the head end through compressed air. The impurities enter the woven bag at the back end through the discharging device for collection.

[0006] Preferably, a cover plate for maintenance is provided at the top of the hopper. The cover plate is hinged to the top plate of the hopper, and a locking buckle is provided on the cover plate, which can be locked with the hopper.

[0007] Furthermore, a vibrator and a level gauge are installed on the side wall of the hopper. The vibrator and the level gauge are interlocked and controlled. When the bottom of the hopper is blocked and the material level rises to the level gauge, the vibrator can be started for vibrating to assist in discharging materials.

[0008] Preferably, the blowing device is a blowing solenoid valve, and the blowing solenoid valve is connected to the fresh chute through a pipeline.

[0009] Preferably, a knife gate valve is provided at the feeding port of the fresh chute. When cleaning the chute, the knife gate valve is closed to prevent impurities from flowing back through the feeding port.

[0010] Preferably, an observation port is further provided on the top plate of the hopper, and the observation port is sealed with transparent plexiglass so as to observe the material level in the hopper without opening the cover plate.

[0011] The beneficial effects of the present utility model compared with the prior art are as follows:

[0012] For the automatic impurity cleaning device of the fresh chute of the present utility model, impurities in the fresh chute are blown towards the discharging device at the head end by the blowing device, and the impurities enter the woven bag at the rear end through the discharging device for collection, preventing the accumulation of impurities inside the chute to ensure the normal transportation of materials, enabling the materials to be evenly mixed with the fluorine-containing flue gas, improving the flue gas purification efficiency and the stability of production materials; the impurity cleaning of the present utility model is automated, without manual cleaning, and the cleaning process is a closed and process-based operation, avoiding the unorganized emission of waste gas.
