Description

Improved thickening device for sulfur concentrate Technical Field The utility model relates to the technical field of mineral separation in the metallurgical industry, in particular to an improved concentration device for sulfur concentrate. Background In the sulfur concentrate beneficiation process, solid and liquid in ore pulp are separated in a concentration and precipitation mode, ore pulp with low solid content (such as 10% -20%) is concentrated into underflow ore pulp with high solid content (such as 45% -55%) through gravity sedimentation, and clear water at the upper part overflows from the upper edge of a concentration tank, so that the purpose of solid-liquid separation is achieved. However, in the actual production process, a multistage sedimentation tank is generally collected for natural concentration and sedimentation, the occupied area of the mode is large, meanwhile, the required concentration and sedimentation time is long, the efficiency of concentrating and sedimentation of sulfur concentrate into underflow ore pulp is low, in order to solve the technical problems, a common rake type concentrator is adopted at present, the mixing of ore pulp and flocculating agent is realized by using a stirring device of the common rake type concentrator, the mode needs an electric drive stirring device, the energy consumption is increased, meanwhile, the structure in the flocculating agent is easily damaged in the stirring process, the flocculating agent is invalid, and the flocculating effect is poor. Disclosure of utility model The utility model aims to provide an improved thickening device for sulfur concentrate, which can reduce energy supply, can fully mix ore pulp with flocculant, can not damage the structure of the flocculant, and can improve the flocculation effect of the ore pulp.
