Rotary self-cleaning divider

Abstract

The invention belongs to the field of coal processing, and discloses a rotary self-cleaning divider which comprises a shell. A rotating shaft is arranged in the shell, a plurality of supporting rods are arranged on the rotating shaft, auxiliary rods are arranged between every two adjacent supporting rods, the supporting rods and the auxiliary rods are telescopic rods, supporting blocks are arranged at the ends, away from the rotating shaft, of the supporting rods and the auxiliary rods, and the supporting blocks are sleeved with skin; the shell is provided with a feeding port and a discharging port. The supporting rods, the auxiliary rods and the supporting blocks support the skin through extension and shortening of the supporting rods and the auxiliary rods, and then the inner wall of the rotary type self-cleaning divider is cleaned through the friction effect of the skin, so that the rotary type self-cleaning divider can work in a division state and a self-cleaning state; the divider has the function of self-cleaning the sample adhered to the surface of the divider, so that the adhesion effect of the obviously humid and high-viscosity coal sample to the divider is reduced, and the trafficability of the obviously humid and high-viscosity coal sample in the divider is enhanced.

Description

technical field [0001] The invention belongs to the field of coal processing and relates to a rotary self-cleaning shrink divider. Background technique [0002] Separation is the most critical step in the process of coal sample preparation, and it is a process in which the particle size of the coal sample remains unchanged but the quality decreases. The purpose of shrinking is to reduce the workload of the next step and gradually reduce the quality of coal samples under the premise of ensuring that the coal samples are representative, so as to finally obtain sufficient samples for testing. The mechanical shrinking device is a mechanical device that takes out a part or several parts of the sample by cutting a large and small sample. High, can reduce the cause of bias caused by sample preparation, and has been widely used. [0003] At present, there are many types of coal used in power plants, and the properties of different types of coal vary greatly. In particular, the qua...
