Corona concentrating machine

Technical Field

The utility model relates to the field of mineral electric separation equipment, in particular to a corona concentrator.

Background

The electric concentrator is a concentrating device for electric concentrating. The working principle is that when various minerals with different electric conductivities pass through an electric field, the minerals have different charges due to the action of electrostatic induction or charged ion capturing, and the minerals have different characteristics in the electric field; the gravity is used as an auxiliary force to generate different motion tracks; then, by means of a receiving device, the purpose of separating minerals with different conductivities is achieved. The working principle of the device is that when various minerals with different electric conductivities pass through an electric field, the minerals have different charges due to the action of electrostatic induction or capture of charged ions and show different characteristics in the electric field; the mining electric separator in the prior art still has many defects that the abrasion of the wool brush roller easily causes incomplete brushing of non-conductor minerals on the outer cambered surface of the rotary drum, the disassembly and the installation of the wool brush roller are inconvenient, and the minerals are easy to block during classified export.

Description of the embodiments

The utility model is described in further detail below with reference to fig. 1:

as shown in fig. 1, a corona concentrator comprising: the high-voltage corona electrode 1, the rotary drum 2, the brush roll 3, the ore separating plate 4, the shell 5 and the ore feeding hopper 6, wherein the rotary drum 2 is arranged above the inside of the shell 5, can rotate, is coaxially connected with a motor and is grounded; the brush roller 3 is adjacently arranged on one side of the rotary drum 2, the distance between the brush roller 3 and the rotary drum 2 is smaller than the cross-sectional diameter of mineral substances, and the brush roller 3 is coaxially connected with another motor; the high-voltage corona electrode 1 is positioned obliquely above the rotary drum 2 and is connected with a high-voltage power supply, and a corona region 7 is formed between the high-voltage corona electrode 1 and the rotary drum 2; the two ore separating plates 4 are positioned at the bottom of the shell, and the bottom of the shell 5 is divided into three areas by the two ore separating plates 4; the ore feeding funnel 6 is arranged above the shell 5, and the funnel opening is opposite to the rotary drum 2; the part of the shell 5 between the two ore separating plates 4 is provided with a discharge hole 51, a conveying device 8 is arranged right below the discharge hole 51, and the tail end of the conveying direction of the conveying device 8 is provided with a collecting box 9.

As shown in fig. 1, the conveyor 8 is preferably a conveyor belt.

The working principle of the corona concentrator of the utility model is as follows:

in the implementation, the high-voltage corona electrode 1 is electrified, minerals to be screened are slowly added into the shell 5 through the ore feeding hopper 6, and the grounded rotary drum 2 rotates clockwise; during the rotation of the drum 2, mineral aggregate is attached to the drum to rotate and enters a corona area 7 between the high-voltage corona electrode 1 and the drum 2; the air is ionized in the corona region 7, and the corona current makes the conductor particles and the non-conductor particles negatively charged; the contact resistance of the conductor particles is small, the charged particles are quickly penetrated through the rotary drum 2 through the grounding, and fall into a right separation area below the shell 5 through inertial motion; the non-conductor particles are worn away after a long time due to the relatively large contact resistance, and when reaching the left side of the rotary drum 2, the non-conductor particles are brushed down by the brush roller 3 and fall into a separation area at the left side; the mixed minerals fall into the middle part and fall into the conveyor belt from the discharge hole 51, are conveyed into the collecting box 9, and are added from the ore feeding hopper 6 after the collecting box is full, so that the aim of circulating ore dressing is fulfilled.

The above embodiments are not intended to limit the scope of the present utility model, so: all equivalent changes in structure, shape and principle of the utility model should be covered in the scope of protection of the utility model.
