Abstract

The invention discloses a coal washing device for improving the cleaning efficiency of the raw coal and facilitating the feeding and discharging. The coal washing device comprises a barrel body, a speed reducer, wherein an upper end cover is arranged on the upper side of the barrel body through bolt, a vibrating rod is arranged inside a feeding hopper, a main shaft is arranged below the speed reducer, a ball is arranged below a supporting rod, a clean coal discharging port is inlaid in the upper portion of the left side of the barrel body, a collecting groove is welded below the outer side ofthe discharging opening, the tail end of a packing auger is connected with a servo motor, a waste discharging port is formed below the right side of the packing auger, and a discharging pipe is weldedbelow the waste discharging port. The cleaning efficiency of the raw coal is improved, the coal washing device convenient for feeding and discharging is provided with the vibrating rod, in the usingprocess, the rotating block makes contact with the vibrating rod through the rotation of the shifting rod, so that the vibrating rod vibrates, so that the flowing speed of the raw coal in the feedinghopper is accelerated, and the problem that the feeding hopper is blocked is effectively solved.

Description

technical field [0001] The invention relates to the technical field of coal washing, in particular to a coal washing device for improving the cleaning efficiency of raw coal and facilitating the feeding and discharging of raw coal. Background technique [0002] Coal washing is a process of operating raw coal. It is a series of processes to separate clean coal, gangue, ash, sulfur and other impurities in raw coal, and then extract the clean coal. The existing coal washing industry uses liquid floating The selection method and the dry selection method have their own advantages and disadvantages. In the existing flotation method coal washing device, some important problems are faced. For example, the flow rate of raw materials inside the feed hopper is relatively slow during feeding, which affects the entire The operating efficiency of the device, and the problem of raw coal clogging often occurs in the feeding hopper. At the same time, during the use of the existing coal washi...
