A phosphoric ore pulp particle separator based on layering separation

Abstract

A phosphoric ore pulp particle separator based on layering separation is disclosed. The separator includes a phosphoric ore pulp feeding pipe, a phosphoric ore pulp tank inlet, a phosphoric ore pulp tank wall, a phosphoric ore pulp tank, a drive motor, a stirring paddle, a phosphoric ore pulp tank outlet, a controllable valve, a phosphoric ore pulp returning pipe and a phosphoric ore pulp discharging pipe. The phosphoric ore pulp tank outlet is disposed between the lower end and the side wall of the phosphoric ore pulp tank to prevent excessive accumulation of phosphoric ore pulp in the phosphoric ore pulp discharging pipe, and therefore, the phosphoric ore pulp can be brought to the phosphoric ore pulp tank outlet in a situation that the stirring paddle rotates without the worry that thephosphoric ore pulp cannot flow out of the phosphoric ore pulp tank. If the phosphoric ore pulp tank outlet is disposed at the lower end of the phosphoric ore pulp tank, phosphoric ore under the function of gravity naturally accumulates toward the phosphoric ore pulp discharging pipe, and if the duration of the accumulation state is long, the phosphoric ore pulp accumulated in the phosphoric ore pulp discharging pipe cannot be stirred and the controllable valve and the phosphoric ore pulp discharging pipe are liable to damage. The separator is simple in structure and reasonable in operation and greatly saves the cost.

Description

technical field [0001] The invention relates to the field of filtration equipment in the production process of phosphorus chemical industry, in particular to a separation device for phosphate rock slurry particles based on layered separation. Background technique [0002] In recent years, phosphate rock resources have become more and more poor, and the application of medium and low-grade phosphate rocks is dominant. Phosphate rocks generally have high hardness and many impurities, resulting in incomplete grinding by ball mills. Avoid containing small particles of phosphate rock and other small particles of impurities. When entering the phosphate rock slurry pump, it is easy to cause the impeller to be stuck, increase the maintenance amount of the slurry pump, and seriously affect production. In response to this phenomenon, the most common method in China is to add a filter screen at the inlet of the phosphate slurry pipe, or add a pair of flanges to the diameter of the slurr...

AI Technical Summary

Problems solved by technology

Using this method, the purpose of filtration is achieved, but when the time is a little longer or there are too many particles, the flow rate of the phosphate slurry pipe will be reduced or even blocked, and the production will inevitably be affected, and the filtration is not layered, it is just a general one-time filtration. The effect is not good, and only a small part of the filtered waste has accumulated and needs to be cleaned up manually, which will consume a lot of manpower and material resources
