Treatment device and treatment method for iron oxide red crude product

Abstract

The invention relates to the technical field of iron oxide red treatment, and discloses a treatment device for an iron oxide red crude product. The treatment device comprises a treatment box, a rotating pipe is arranged in the treatment box, the outer wall of the rotating pipe is rotationally connected with the treatment box through a first bearing, a ball milling pipe and a conveying pipe are arranged in the rotating pipe, a plurality of grinding balls are arranged in the ball milling pipe, one end of the ball milling pipe is fixedly connected with one end of the conveying pipe, the other end of the ball milling pipe and the other end of the conveying pipe are rotationally connected with the rotating pipe through second bearings, the outer wall of the conveying pipe is fixedly sleeved with a spiral blade, the spiral blade is matched with the rotating pipe, a baffle is fixed in the conveying pipe, and a first discharging opening is formed in the side wall of the conveying pipe. According to the treatment device and the treatment method for the iron oxide red crude product, the iron oxide red crude product can be ground and subjected to solid-liquid separation in a centrifugal mode, the recovery rate and the recovery quality of the iron oxide red are improved, meanwhile, the separated liquid can be recycled, and the treatment cost is reduced.

Description

technical field [0001] The invention relates to the technical field of red iron oxide treatment, in particular to a treatment device and method for crude iron oxide red. Background technique [0002] Iron oxide red, the main component is ferric oxide, chemical formula: a-Fe2O3, is a non-toxic red or dark red amorphous powder, is a very important inorganic color pigment, with good pigment quality, application field Very broad. [0003] At present, the iron oxide red crude product is obtained by roasting, and then the iron oxide red crude product is washed and dried to obtain the iron oxide red product. However, in the prior art, the iron oxide red is easily settled by washing and drying, resulting in a low recovery rate. The problem is that iron oxide red particles cannot be processed during the processing process, resulting in different particle sizes and affecting the quality of the product.

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a treatment device and method for crude iron oxide red, which can grind the crude iron oxide red and separate it from solid and liquid by centrifugation, thereby improving the efficiency of iron oxide red. high recovery rate and recovery quality, and at the same time, the separated liquid can be recycled, which reduces the cost advantage of treatment, and solves the problem of low recovery rate caused by easy sedimentation when the iron oxide red is processed by washing and drying in the prior art. And in the process of processing, iron oxide red particles cannot be processed, resulting in different particle sizes and affecting product quality.
