Mill and non-deslagging side material cleaning device thereof

Abstract

The invention discloses a mill and a non-deslagging side material cleaning device thereof. The non-deslagging side material cleaning device comprises a rotor arranged on the inner side of a collecting hopper of an air inlet pipe on the non-deslagging side, a material conveying space is arranged on the periphery of the rotor, the material conveying space on the upper side of the rotor is arranged in the air inlet pipe on the non-deslagging side, the middle of the material conveying space is fixed to the upper end of a rotating shaft, the collecting hopper comprises an inclined plate obliquely arranged on the side close to a scraping plate, and a through hole is formed in the inclined plate. The rotating shaft penetrates through the through hole from inside to outside, the middle of the rotating shaft is connected with a supporting seat bearing, the upper end of the supporting seat is fixedly connected with the inclined plate, and the lower end of the rotating shaft is connected with a speed reducer. According to the mill and the non-deslagging side material cleaning device thereof, materials accumulated on the non-deslagging side can be emptied in time, smooth, stable and uniform ventilation of the air inlet pipe is maintained, the operation working condition of the vertical mill is better, and the efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of a grinding machine and its non-slagging side cleaning device, in particular to a grinding machine and its non-slagging side cleaning device. Background technique [0002] Vertical mill is currently the most popular large-scale grinding equipment at home and abroad. It integrates grinding and drying, and is widely used in slag grinding in steel plants, raw meal and clinker grinding in cement plants, etc. Compared with other grinding equipment, the vertical mill has the characteristics of high grinding efficiency, small footprint, adjustable grinding fineness, low noise, low power consumption, and low component wear. As the size of the vertical mill increases, the mill often adopts multiple air inlet pipes to enter the air, while the slag discharge system of the mill is generally only provided with one, and baffles are often installed on the non-slag discharge side to reduce the accumulation of materials. ...

Problems solved by technology

Through long-term operation observation, these measures can only work in the short term. When the mill is running in an unstable state, the air inlet pipe on the non-slag discharge side will be filled with materials soon. Even if the mill is running in a stable state, after After a period of time, the air inlet pipe on the non-slag discharge side will also be filled with materials. If the air inlet is blocked, the ventilation effect of the vertical mill will be seriously affected. The air volume of the two air inlet pipes will be unbalanced, and the condition of the mill will also be unstable.

Therefore, at this time, it is necessary to manually clean the material through the slag discharge port placed on the air duct. The workload of manual cleaning workers is large, and the operation is inconvenient. Some sites have small spaces and do not even have the conditions for manual material cleaning. The mill has been in an unstable production state
