Coal washing mechanism with filtering mechanism for separating wastewater

Abstract

The invention discloses a coal washing mechanism with a filtering mechanism and for separating waste water, and belongs to the technical field of coal washing mechanisms. The coal washing mechanism comprises a machine shell, a combined connecting piece, a dewatering mechanism, a vibration shell and a vibration block, a water collecting shell is fixedly installed on the inner wall of the top face of the machine shell, water spray heads are fixedly installed at the bottom of the water collecting shell, and a dewatering mechanism is rotatably mounted in the center of the bottom of the water collecting shell on the two sides of the water spray heads; According to the coal washing mechanism, the dewatering mechanism is arranged in the coal washer and consists of dewatering blades, a mounting shaft and a shaft sleeve, and the inclined water spray heads are arranged on the two sides of the dewatering mechanism correspondingly due to the inclined surface design of the dewatering blades, so that the inclined water spray heads spray water during coal washing, and different pressures can be generated on the inclined surfaces of the dewatering blades; and due to the fact that stress on the dewatering blades is uneven, the dewatering blades can rotate around the mounting shaft, water on the dewatering blades can be dispersed, the spraying range and the spraying width of coal washing liquidare greatly increased during coal washing, and the coal washing effect is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of coal washing mechanisms, and in particular relates to a coal washing mechanism with a filtering mechanism for separating waste water. Background technique [0002] Coal washing is an indispensable process of coal deep processing. Generally, the coal mined directly from the mine is called raw coal. Raw coal is mixed with many impurities during the mining process, and the quality of coal is also different. Coal with small internal ash content and large internal ash content are mixed. Together, coal washing, as the name suggests, is an industrial process that removes impurities in raw coal, or classifies high-quality coal and low-quality coal, and is widely used in the coal mining industry. [0003] Compared with the Chinese patent (CN201921424559.1), a coal washing device for coal mines, including a working body, the bottom of the working body is fixedly connected and connected with a gangue outlet, and the...
