Description

Technical Field

[0001] This utility model relates to the technical field of material stacking devices, and in particular to a material stacking device for a cement production line reducer. Background Technology

[0002] The vertical mill in a cement production line is an ideal large-scale grinding equipment. It drives the grinding disc to rotate through a motor and reducer. The material falls from the feed port to the center of the grinding disc and moves towards the edge of the grinding disc under the action of centrifugal force and is crushed by the grinding rollers. The crushed material overflows from the edge of the grinding disc and is carried by the high-speed upward hot airflow from the nozzle ring (air ring) to the high-efficiency air classifier integrated with the vertical mill. The coarse powder is separated by the separator and returned to the grinding disc for re-grinding. The fine powder is discharged from the mill with the airflow and collected in the dust collection device of the system, which is the product. Coarse particles and accidentally entered metal parts fall from the air ring to the slag discharge bin, are scraped out by the scraper, and are fed into the mill again for re-grinding by the external circulation bucket elevator.

[0003] During the production process, due to the crushing of the grinding rollers and the influence of negative pressure air, the messy material on the grinding disc falls into the slag discharge bin through the nozzle ring. When the dust seal at the connection between the reducer output shaft and the grinding body is worn significantly, the material that is not cleaned in time will pass over the cleaner and overflow from the reducer output shaft end. The overflowing material aggravates the wear of the seals, pollutes the on-site environment, increases the system air leakage, and increases the workload of workers. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a material stacking device for a cement production line reducer that achieves the effect of preventing material leakage, reducing the labor intensity of workers in cleaning, reducing maintenance costs, and increasing equipment operating rate.

[0005] This utility model discloses a material stacking device for a cement production line reducer, comprising a machine body and a grinding roller, the grinding roller being rotatably mounted on the machine body; it also includes a cleaning device, a conveying device, a reducer, a slag discharge bin, and an annular retaining ring. The reducer is mounted on the outer wall of the machine body, the slag discharge bin is mounted on the outer wall of the machine body and is connected to the grinding chamber of the machine body, the annular retaining ring is mounted on the lower part of the outer wall of the slag discharge bin and is located in front of the reducer, the cleaning device is located in the lower part of the slag discharge bin and is used to clean the material, and the conveying device is located inside the slag discharge bin and is used to convey the material. During production, under the influence of the grinding rollers and negative pressure air, the disordered material on the grinding disc falls into the slag discharge bin through the nozzle ring. Most of the material is conveyed to the discharge chute by the conveying device at the front end of the slag discharge bin and then transferred to the external circulation. The remaining small part of the material is cleaned by the cleaning device. By setting the annular retaining ring between the slag discharge bin and the front of the reducer, the annular retaining ring blocks the remaining small part of the material, thereby preventing the material from moving towards the reducer, thus achieving the effect of preventing material leakage, reducing the labor intensity of workers in cleaning, reducing maintenance costs, and increasing equipment operating rate.

[0006] Preferably, the conveying device includes a scraping assembly and a cleaning assembly. The scraping assembly is arranged inside the slag discharge bin by means of a power assembly and a scraper, and the cleaning assembly is arranged inside the slag discharge bin by means of a power assembly and a brush. The power assembly drives the scraping assembly to move back and forth, thereby scraping and conveying the material. By activating the cleaning assembly, the cleaning assembly cleans up the remaining material and reduces material leakage.

[0007] Preferably, it also includes a bottom plate, which is connected to the bottom of the slag discharge bin; by opening the bottom plate, the ease of operation for cleaning and maintenance inside the slag discharge bin is improved.

[0008] Preferably, it also includes an inclined surface, which is set on the cleaning component; by setting the inclined surface, the size of the cleaning component is reduced, the gap between the rear end of the cleaning component and the slag discharge chamber is increased, allowing more material to accumulate in the space, and at the same time, the material's natural accumulation angle and the annular retaining ring are used to form an accumulation, thereby achieving the effect of preventing material leakage.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: During the production process, under the influence of the grinding roller and negative pressure air, the disordered material on the grinding disc falls into the slag discharge bin through the nozzle ring. Most of the material is conveyed to the discharge chute by the conveying device at the front end of the slag discharge bin and then transferred to the external circulation. The remaining small part of the material is cleaned by the cleaning device. By setting the annular retaining ring between the slag discharge bin and the front of the reducer, the annular retaining ring blocks the remaining small part of the material, thereby preventing the material from moving towards the reducer, thus achieving the effect of preventing material leakage, reducing the labor intensity of workers in cleaning, reducing maintenance costs, and increasing equipment operating rate.
