Description

TECHNICAL FIELD

[0001] The utility model relates to coal slime production and processing technical field, concretely is a coal slime dewatering device. BACKGROUND

[0002] Coal slime refers to semi-solid material formed by coal powder containing water, which is a byproduct in the process of coal production. According to different causes, it can be divided into primary coal slime and exogenous coal slime. Due to the existence of a large number of negative charges on the surface of coal slime particles, like charges repel each other, so that the coal slime particles can maintain a dispersed state in water. In addition, coal slime contains a high content of clay minerals, which makes coal slime have high cohesiveness. The coal slime of most coal preparation plants refers to the product obtained after the coal slime water in the washing and processing process is concentrated and dewatered. In order to improve the quality of coal slime and facilitate storage and transportation, a dewatering device needs to be used during the production and processing of coal slime.

[0003] The common coal slime dewatering device is usually composed of a box body, a screening plate, a drainage plate, an inlet, an outlet and a drainage port. The coal slime is first introduced into the box body through the inlet, so that the coal slime falls to the top of the screening plate, and the water in the coal slime is discharged downward through the drainage holes on the screening plate, so that the water falls to the drainage plate and is discharged to the outside of the box body through the drainage port. At the same time, the dewatered coal slime can be outputted to the outside of the box body through the outlet.

[0004] The traditional coal slime dewatering device has a screening plate and a drainage port uniformly arranged on the surface of the device. When the coal slime is transported to the top of the screening plate, the liquid in the coal slime is discharged downward along the drainage port. Since the coal slime accumulates on the top of the screening plate, not only the dewatering effect of the screening plate is reduced, but also the dewatering efficiency is reduced. To solve the above problems, some coal slime dewatering devices are provided with a centrifugal barrel, a motor and a drainage groove. The drainage groove is arranged on the surface of the centrifugal barrel. The coal slime is first transported into the centrifugal barrel, and then the centrifugal barrel is rotated by the motor, so that the coal slime adheres to the inner wall of the centrifugal barrel, and the water in the coal slime is discharged to the outside of the centrifugal barrel by centrifugal force and the drainage groove. Not only the dewatering effect of the coal slime is improved, but also the dewatering efficiency is increased. However, since the coal slime adheres to the inner wall of the centrifugal barrel after centrifugal dewatering, not only the cleaning difficulty of the coal slime is increased, but also the coal slime is not convenient to take. Therefore, a coal slime dewatering device is proposed. TECHNICAL FIELD
