Description

A powder sorting machine

technical field

The device belongs to the field of powder metallurgy, and specifically relates to a powder sorting machine, which is especially suitable for sorting powders with the same specific gravity, close particle size and large shape difference. It is mainly used to separate flake powder from spherical powder with the same material and similar particle size.

Background technique

The spherical powder produced by the plasma rotating electrode milling process often has a large amount of flake powder. After grading by a sieving machine or a grading system, the spherical powder and flake powder of the same size are still mixed together and cannot be separated. The specific gravity is the same, and there is no equipment on the market to separate the two. Due to the existence of flake powder, the quality of the powder produced by the plasma rotating electrode powder making process is seriously affected. At present, in order to improve product quality, enterprises often use screening machines to remove large-size flake powder and spherical powder together, so as to reduce the impact of large-size flake powder on powder quality, while small-size flake powder still cannot be removed.

Contents of the invention

In order to overcome the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a powder sorting machine, which solves the problem of flake powder in spherical powder, removes flake powder from spherical powder, has simple structure and improves powder quality features.

In order to achieve the above object, the technical solution adopted in the present invention is: a powder sorting machine, including a base with a tank body, an upper receiving port, a lower receiving port, an upper receiving port, Both sides of the lower receiving port are slopes, on which the upper roller is installed, and the transmission motor 4 is set on the slope, and the driving motor is connected with the upper roller, and the lower roller is arranged on the upper part of the lower receiving port; between the upper roller and the lower roller A belt is provided, and the bottom of the belt is tangent to the upper roller brush and the lower roller brush; the upper roller brush and the lower roller brush are respectively fixed in the two receiving ports of the slope.

The slope is an angle-adjustable slope.

The beneficial effects of the present invention are:

The present invention mainly utilizes the difference in fluidity between flake powder and spherical powder, and the mixed flake powder and spherical powder evenly and slowly fall on the belt with a certain angle, and the belt moves upward to take away the fluidity. Poor flaky powder, under the action of the upper roller brush, the flaky powder is collected from the upper receiving port of the slope; due to the better fluidity of the spherical powder, after the spherical powder touches the belt, the spherical powder will It falls into the lower receiving port of the slope along the belt surface, and then is collected. The lower roller brush mainly cleans the spherical powder adhered to the belt surface due to static electricity. Powders with similar sizes and different shapes can be separated by such a device. Different metal powders and different belts have different adsorption capabilities. You can also adjust the slope angle, belt material and powder feeding speed to control the separation effect. By adjusting the angle of the slope, it is possible to separate powders of the same material, the same size and different shapes.

The invention has the characteristics of quickly and effectively sorting powders with the same specific gravity and similar size with large shape differences. Especially for the sorting of flake powder and spherical powder with smaller sizes.

detailed description

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

Referring to Fig. 1, a powder sorting machine includes a base 10, an upper material receiving port 11 and a lower material receiving port 12 are respectively arranged on both sides of the base, the two sides of the upper material receiving port and the lower material receiving port are slopes, and the slopes An upper roller 5 is installed on the top, and the transmission motor 4 is set on the slope. The transmission motor 4 is connected to the upper roller 5, and the lower roller 8 is arranged on the upper part of the lower receiving port; a belt 1 is provided between the upper roller and the lower roller, and the belt 1 The bottom of the bottom is tangent to the upper roller brush 6 and the lower roller brush 7; the upper roller brush 6 and the lower roller brush 7 are respectively fixed in two receiving ports of the slope.

The slope is an angle-adjustable slope.

By adjusting the angle of the slope, it is possible to separate powders of the same material, the same size and different shapes.

The upper roller 5 is installed on the angle-adjustable slope 9 with two material receiving ports, the transmission motor 4 is located on the angle-adjustable slope 9 with two material receiving ports and connected with the upper roller 5, the upper roller brush 6 and the lower roller brush 7 are respectively fixed in the two receiving openings of the slope 9 tangentially with the belt 1, and the lower drum 8 is fixed on the upper part of the lower receiving opening, and the flake powder 2 and the spherical powder 3 fall on the belt 1.

In addition, the transmission motor is fixed by the motor seat, and the upper roller and the lower roller are fixed by the bearing seat.

Working principle: start the transmission motor 4, the motor drives the upper roller 5 to rotate, the upper roller 5 is the active one, the lower roller 8 is the driven one, the belt 1 rotates around the upper roller 5 and the lower roller 8, the flake powder 2 and the spherical powder 3 fall to the After the belt 1 is on the top, due to the different fluidity of the two, the flake powder is moved by the belt 1 in the direction of the upper roller brush 6, and finally, under the action of the upper roller brush 6, the flake powder 2 enters the upward collection of the slope. Powder outlet; the spherical powder 3 will enter the lower powder inlet of the slope 9 due to its good fluidity. The flake powder 2 mixed together and the spherical powder 3 just can be separated by such a device.
