Embodiment 1

[0023] Embodiment 1: A needle electrode arrangement device for a high-voltage electrostatic separator.

[0024] Such as Figure 1~Figure 3 As shown, the device of the present invention includes a circular tubular shell 1, a metal mesh filled column 2, a needle electrode 3 and a negative high-voltage power supply 4 and other parts.

[0025] The shell 1 is an insulated hollow tubular structure made of polytetrafluoroethylene material with good high-voltage insulation performance. It is arranged inside the sorting machine and arranged parallel to its rotating roller to carry the needle electrode 3 . Two axial long holes are opened on the tube wall of the shell 1, which are respectively the first long hole 5 and the second long hole 7, and the first long hole 5 and the second long hole 7 are related to the shell 1. The central axis is symmetrical to form an insertion opening through which the needle electrodes 3 are arranged. The length of the long hole is slightly shorter than ...

Embodiment 2

[0027] Embodiment 2: A needle electrode arrangement method of a high-voltage electrostatic separator.

[0028] The inventive method comprises the following steps:

[0029] a. Set the needle electrode arrangement device of the high-voltage electrostatic separator described in Example 1.

[0030] b. Insert the needle electrodes 3 vertically from the long holes on the housing 1 so that they penetrate the metal mesh filled column 2, and make the tip of each needle electrode 3 point vertically to the roller shaft of the high-voltage electrostatic separator, and turn on the high-voltage power supply , all the needle electrodes 3 produce a discharge phenomenon for the roller, and the electric field intensity is measured and calculated.

[0031] c. Repeat step b according to the designed arrangement spacing of the needle electrodes and the distance between the tips of the needle electrodes and the surface of the roller.

[0032] d. According to the measured and calculated electric f...

Abstract

The invention relates to an arrangement device and an arrangement method for pin electrodes in a high-voltage electrostatic separator. The device comprises the pin electrodes, electrode carriers and a negative-high-voltage power supply, wherein each electrode carrier comprises an insulated circular-tube-shaped housing and a reel-shaped metal mesh filling column; two axial strip holes are formed in the outer-circle surface of each housing, and are symmetrical about the central axis of the housing to form a penetration port for penetrating the corresponding pin electrode; a circular-barrel-shaped inner cavity of each housing is filled with the corresponding metal mesh filling column, and the corresponding metal mesh filling column is tightly jacked on the inner-circle surface of the inner cavity, the central axis of each metal mesh filling column is superposed with the central axis of the corresponding inner cavity, and the length of each metal mesh filling column is not less than the length of the corresponding inner cavity, for forming location for the corresponding pin electrode; and one end of each metal mesh filling column is connected with the negative-high-voltage power supply through a conductive wire. According to the invention, the problem that the positions of pin electrodes cannot be freely adjusted in the existing arrangement device is solved, and the optimal arrangement manner for the pin electrodes can be chosen, which are of great significance to improvement for a corona electrode structure of a pin-roll type high-voltage electrostatic separator.

Description

technical field [0001] The invention relates to a device and method for arranging needle electrodes, in particular to a device and method for arranging needle electrodes in a high-voltage electrostatic separator. Background technique [0002] High-voltage electrostatic separator is mainly composed of high-voltage electrostatic generator, shell, insulating plate, material conveying plate chain, power wheel, rotating roller, discharge electrode and recovery plate chain, etc. It is used to separate the mixture of conductors and non-conductors. Electrostatic separation is a clean separation technology that will not cause serious water pollution like general industrial separation, so it is widely used in industrial mineral processing and waste treatment and other fields. The working principle of the high-voltage electrostatic separator is: when the material passes through the high-voltage electric field formed by the action of the rotating roller and the corona electrode, it will...
