Embodiment 1

[0041] combine Figure 1-2 , a device for removing material and debris in this embodiment includes a screen 1, wherein the screen 1 includes a screen bar 14, a sleeve 11, a base 12 and a frame 13, the screen 1 is located in the hopper, and the upper part of the screen 1 is located Below the upper belt, that is, below the scraper blade of the upper belt head pulley, such as figure 2 As shown; the bottom of the screen 1 is provided with a transmission shaft 2, and the transmission shaft 2 is connected with the transmission connecting rod 4, as figure 1 shown.

[0042] Below the base 12 of screen cloth 1 is provided with inclined chute, and inclined chute is positioned at the outside of hopper, as figure 2 As shown, when the screen cloth 1 is not in use, the plane where the screen cloth 1 is located is in the vertical direction.

[0043] The two ends of the transmission shaft 2 are connected with the bearing seat 3, the bearing seat 3 is located on the hopper, the transmissi...

Embodiment 2

[0050] A kind of method for removing material sundries of the present embodiment, comprises the following steps:

[0051] Step A, build the above-mentioned a kind of device for removing material and sundries, the screen 1 is in a vertical state;

[0052] Step B, the motor runs to drive the transmission connecting rod 4;

[0053] Step C, the transmission connecting rod 4 simultaneously drives the transmission shaft 2 to move;

[0054] Step D, the transmission shaft 2 and the screen 1 are connected through the base 12, the bearing seat 3 drives the base 12 to move, and the angle between the plane where the screen 1 is located and the horizontal direction changes;

[0055] Step E, the screen 1 continues to move and touches the support block in the hopper, or after the transmission connecting rod 4 reaches the position of the limit switch, the limit switch sends a signal to the motor, the motor stops running, and the transmission connecting rod 4 and the transmission shaft 2 and...

Embodiment 3

[0061] A device for removing material debris in this embodiment is installed at the head wheel of the incoming material belt. The upper part of the screen 1 is below the scraper of the upper belt head wheel, and the lower part is at the front of the hopper. The angle between the plane where the screen 1 is located and the horizontal direction is 75°, the lower part of the screen 1 passes through the inclined chute, and the sundries can be introduced into the belt platform below, and the holes are drilled at the platform position with a length of 1200mm * a width of 650mm, and the sundries are led to the first floor, and the sundries are transported regularly every week.

[0062] Such as figure 2 As shown, the mark A indicates the position of the screen 1 when it is not in use, and the mark B indicates the position of the screen 1 when it screens out the sundries in the incoming material; When passing through the screen 1, the debris enters the debris pile through the inclined...

Abstract

The invention discloses a materials and sundries clearing device and a method thereof, which belongs to the technical field of mineral screening. The device includes a screen which consists of a grating, a sleeve, a base and frames. The screen is located in the hopper and the upper part of the screen is located under a scraper blade of an upper belt head wheel. A transmission shaft is arranged in the bottom of the screen and connected to a transmission connecting rod. An inclined chute is arranged under the base of the screen and is located outside the hopper. The method includes the steps that the transmission connecting rod is driven through a motor, the transmission connecting rod drives a transmission shaft to adjust the angle between the plane where the screen is located and the horizontal direction to be over 70 DEG C and less than 90 DEG C. The materials drop on the belt through the screen and the sundries are left on the screen. Affected by their own action of gravity, the materials and sundries move downward the plane where the screen is located and pass the inclined chute. Then the device separates the materials and sundries and can effectively eliminate the sundries in the material, satisfying the requirements of pelletizing process operation. The device can be used to eliminate the sundries in the materials like concentrate fines.

Description

technical field [0001] The invention relates to the technical field of mineral screening, in particular to a device and method for removing material impurities. Background technique [0002] There are many impurities in the pellet raw material concentrate powder, which has not been completely resolved, which affects the process operation of the pelletizing system. Domestic general impurity removal equipment includes electromagnetic iron remover and roller screen impurity removal equipment. Electromagnetic equipment for iron parts in non-magnetic materials is generally installed at the head or middle of the belt conveyor. The strong magnetic force generated by the electrification will pick up the iron parts mixed in the material and throw them out from the unloading belt to achieve the purpose of automatic removal. , but concentrate powder materials are not suitable for this equipment; roller sieve impurity removal equipment is used to sieve raw ball powder, unsuitable for si...
