Ore pulp distributing and guiding device

Abstract

The invention discloses an ore pulp distributing and guiding device to solve the problem of unreasonable material distribution of conventional concentration tanks. The device is characterized in thata distributing and guiding device body is arranged below an outlet of a material distributing cylinder and comprises a static inner flow guide cover located at an upper position and a rotary outer flow guide cover located at a lower position, wherein the small end of the inner flow guide cover is connected with a central strut, and the large end of the inner flow guide cover is provided with a lower flange; and the outer flow guide cover is fixed on a rotating cage, the small end of the outer flow guide cover extends into the lower flange and is overlapped with the inner flow guide cover, thelarge end of the outer flow guide cover is positioned outside the rotating cage, and the diameter of the outer flow guide cover is greater than the diameter of a collecting hopper. The ore pulp distributing and guiding device changes flow direction and prevents coarse particle solids from directly sinking into the collecting hopper; the rotary outer flow guide cover is adopted, so secondary material distribution is achieved, and deflected settlement is eliminated; solids settled at the bottom of a pond is scraped and collected to the collecting hopper through a material scraping rake and are discharged out of the collecting hopper in time, so the collecting hopper is free of material accumulation and hardening which will leads to blockage of a discharging pipe; and discharging is smooth, overflow solid content and underflow concentration are stable, and a mud scraping rake works stably.

Description

technical field [0001] The invention relates to a diversion device, specifically a material distribution diversion device for a thickening tank with a central pillar and feeding pulp from the upper part of the center. Background technique [0002] It is a method widely used in the liquid-solid separation process to use a concentration tank for gravity settling to obtain an overflow with a low solid content and a high-concentration underflow, and then dehydrate the high-concentration underflow. In industrial production, concentration and sedimentation is a continuous process. Low-concentration liquid-solid mixture—ore pulp, continuously enters the thickening tank for gravity settlement, the liquid rises and overflows through the overflow weir at the upper part of the thickening tank; the solid settles at the bottom of the thickening tank, and is continuously scraped and collected to the bottom center of the thickening tank by the scraping rake of the thickener The inside of ...

Problems solved by technology

In addition, due to the increase in the amount of solids in the thickening tank, the scraping resistance increases, resulting in overload shutdown

[0005] In order to solve this problem, the engineering and technical personnel of the thickener manufa
