An anti-blocking and dredging device for the discharge port of a ball mill

Abstract

The invention discloses an anti-blocking dredging device for a discharge port of a ball mill. The anti-blocking dredging device comprises a hopper, a discharge pipe, the ball mill, a belt conveyor anda drilling machine; the hopper is provided with a sieve plate and a material blocking apron; the sieve plate is formed through combination of an upper sieve plate and a lower sieve plate; the upper sieve plate is connected to the right side of the rear end of the hopper through a rotating shaft; the lower sieve plate is connected on the left side of the rear end of the hopper through the rotatingshaft; each of the upper sieve plate and the lower sieve plate is provided with a round opening and a through hole; the material blocking apron is welded on the outer side of the hopper; the discharge pipe is in pipe connection at the bottom part of the hopper through an upper pipe section; an alkaline liquor pipe is in pipe connection between the discharge pipe and the upper pipe section; a material return pipe is welded at the rear end of the discharge pipe and is in pipe connection with the material blocking apron; the ball mill is installed at the rear end of the discharge pipe; the rearend of the discharge pipe is inserted into a feed port of the ball mill; the belt conveyor is installed above the hopper; and the drilling machine is installed right above the hopper. The anti-blocking dredging device can effectively prevent the phenomenon of blockage of the discharge pipe.

Description

technical field [0001] The invention relates to an anti-blocking and dredging device for a feeding port of a ball mill, belonging to the technical field of alumina production equipment. Background technique [0002] The production of alumina by the Bayer method is the main process for the production of alumina at present. It is roughly mixed with ore raw materials and lye to grind into a slurry, and then the qualified alumina is prepared through processes such as dissolution, sedimentation, decomposition, and roasting; and prepared from the slurry During the process, large pieces of ore often get stuck in the discharge pipe of the ball mill, and the stuck ore is often covered with thick ore and slurry. It is very time-consuming and laborious to open the discharge port manually, ranging from more than ten minutes to nearly an hour at most. , resulting in interruption of raw material supply, seriously affecting product quality and increasing costs. In order to solve the above...
