Technical Field

The invention relates to an efficient demagnetizing and sorting cavity, and belongs to the technical field of ore sorting equipment.

Background

The non-metal ore is an important industrial mineral except for the metal ore, is widely applied to the traditional industries such as building materials, chemical industry, energy, light power and the like and the high and new technology industries such as aerospace, electronics, communication, new materials and the like, and is also widely applied to the aspects of environmental protection, new energy and the like in the present year, so that the rapid development of the non-metal ore industry is strongly promoted to the rapid development of national economy.

The non-metallic mineral materials generally have high purity requirements, the impurity content often determines the quality grade of products, particularly the iron content in the products, and iron removal operation is generally required in the processing process of non-metallic ores. The iron impurities in the nonmetallic minerals have the characteristics of low content, weak magnetism, fine granularity, difficult removal and the like, and materials with different properties need different methods for iron removal operation. The magnetic separation is a method for removing iron from non-metal ores, which has wider application and is more effective.

Disclosure of Invention

The invention aims to solve the technical problems, and provides a sorting device for non-metal ores, which has the advantages of reasonable structural arrangement, high sorting efficiency, high purity of sorted concentrate, small resistance to ore pulp when the ore pulp passes through, easiness in flushing, difficulty in pressing and hardening, convenience in disassembly and assembly and the like.

In order to solve the above problems, the technical scheme adopted by the invention is as follows:

a sorting device for nonmetallic ores comprises a sorting cavity and a plurality of steel wool cakes arranged at intervals in the sorting cavity, wherein a steel plate net is arranged between every two adjacent steel wool cakes; the edge of the steel wool cake is in close contact with the inner wall of the sorting cavity, so that slurry leakage is prevented.

As an improvement, the specification of the steel wool cakes is coarse steel wool cakes and fine steel wool cakes, the coarse steel wool cakes and the fine steel wool cakes are alternately arranged in the separation cavity along the flow direction of the ore pulp, and the ore pulp firstly flows through the coarse steel wool cakes and then flows through the fine steel wool cakes.

As an improvement, the filling amount of the steel wool cakes in the separation cavity is 5-7%. Wherein the ratio of the coarse steel wool cake to the fine steel wool cake is 4:6 to 5: 5.

As an improvement, hard steel nets are arranged at two ends of the inner side of the sorting cavity.

As an improvement, the thickness of the steel plate net is 0.5-1.2 mm; the grid specification is 3mmx5mm or 4mmx6 mm.

As an improvement, two ends of the separation cavity are respectively provided with an ore pulp inlet and an ore pulp outlet.

As an improvement, a gap is formed between the edge of the steel plate net and the inner wall of the separation cavity, so that the steel plate net and the separation cavity can be conveniently disassembled and assembled.

As an improvement, the steel wool cake is formed by drawing a magnetic conductive medium rod into a metal wire with the diameter of 0.05-0.2 mm and then paving the metal wire; the cross-section of the wire is circular.

As an improvement, a detachable end cover is fixed at one end of the sorting cavity; the steel wool cake and the steel plate net can be conveniently disassembled and replaced.

As an improvement, the middle part of the separation cavity is provided with a fixing frame penetrating through two ends, and the centers of the steel wool cake and the steel plate net are both provided with through holes; the steel wool cake is tightly contacted with the fixed frame to prevent slurry leakage; a gap is arranged between the through hole of the steel plate net and the fixing frame, so that the steel plate net is convenient to disassemble, assemble and replace.

By adopting the technical scheme, compared with the prior art, the invention has the following advantages:

because the steel plate net is arranged between the adjacent steel hair cakes and has a manufacturing effect on the steel hair cakes, the steel hair cakes can not curl, hold or be pressed under the action of a magnetic field and the action of slurry flow, the resistance of the slurry is small when the slurry passes through, the slurry is fully contacted with the steel hair cakes, and magnetic substances are separated from the slurry.

The steel wool cake is made by drawing a magnetic conductive medium rod into a metal wire with the diameter of 0.05-0.2 mm and then winding the metal wire; the cross-section of the wire is circular. The steel wool cakes with the same mass have the largest surface area, can be fully contacted with ore pulp, and improve the separation rate. And the resistance of the round steel wire to the ore pulp is small, and the requirement on the conveying pressure of the ore pulp during ore dressing is lower than that of common steel wool. After the steel wool cake is demagnetized, the surface of the steel wire is smooth and easy to wash, and the washing is cleaner, so that the phenomenon of pressing knots can not occur.

The sorting device for the non-metallic ores has the advantages of reasonable structural arrangement, high sorting efficiency, high purity of the sorted concentrate, small resistance to the ore pulp when the ore pulp passes through, easiness in flushing, difficulty in pressing and hardening, convenience in disassembly and assembly and the like.
