Description

Technical Field

[0001] The invention relates to the field of non-metallic ore dressing, in particular to a re-selection and band-cutting device for purifying zirconium-titanium ore. Background Art

[0002] In the prior art, the beneficiation and purification of zircon-titanium ore utilizes the characteristic that its density is much higher than that of silicate minerals, and separates the heavy minerals containing zirconium and titanium under the action of gravity. However, due to the uneven feeding of gravity separation, the width of the spiral band of zircon-titanium ore gravity separation also changes, resulting in the following problems: if the band width is greater than the cut-off band, part of the concentrate will enter the tailings, and the recovery rate of heavy minerals will be lost; if the band width is less than the cut-off band, part of the tailings will enter the concentrate, and the grade of heavy minerals will be reduced. In severe cases, rework is required. Therefore, manual assistance is required to adjust the position of the cut-off baffle in the gravity separation operation, which not only wastes manpower, but also introduces human errors. Summary of the invention

[0003] The present invention aims to overcome the deficiencies in the prior art and provides a gravity separation and interception device for purifying zirconium-titanium ore.

[0004] The present application provides the following technical solutions: a re-selection and intercepting device for purifying zircon-titanium ore, which comprises a pillar, a spiral chute is surrounded on the pillar, a corresponding feeder is provided at the upper end of the spiral chute, and a corresponding receiving trough is provided on one side of the discharge end of the spiral chute, characterized in that a rotatable material distribution guide block is provided in the trough body at the discharge end of the spiral chute, a rotating motor corresponding to the material distribution guide block is provided at the discharge end of the spiral chute, a camera for irradiating downward is provided on the spiral chute above the material distribution guide block, a partition is provided in the receiving trough, and the receiving trough is divided into a concentrate trough and a tailings trough by the partition, and a control module is provided to form an electrical signal control cooperation with the rotating motor and the camera.

[0005] On the basis of the above technical solutions, there can also be the following further technical solutions: A material guide plate distributed longitudinally is arranged on the upper surface of the material distribution guide block.

[0006] The upper end of the partition extends out of the bottom surface of the trough body at the discharge end of the spiral chute for a distance.

[0007] The material distribution guide block is approximately triangular in shape, with its tip located at the material incoming side and its connection end with the rotating motor close to the material receiving trough side.

[0008] Advantages of the invention: The present invention has a simple structure and is easy to use. It controls the swing of the dividing guide block by the difference in specific gravity of the minerals and the color difference fed back by the camera to distinguish the concentrate from the tailings. It is suitable for all mineral processing and purification processes containing the above two characteristics, and can solve a series of problems caused by uneven feeding in subsequent work stages to the greatest extent, especially for precious minerals such as rare earths, ThO2 and HfO2, and recovers great economic benefits. In addition, the method improves the automation level of the mineral processing plant and saves labor costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a structural schematic diagram of the present invention. DETAILED DESCRIPTION

[0010] like Figure 1 As shown, a re-selection and intercepting device for purifying zircon-titanium ore comprises a support 1, a spiral chute 2 is surrounded on the support 1, and a feeder (not shown in the figure) is installed on the upper end of the spiral chute 2.

[0011] A receiving trough 3 is provided on one side of the spiral chute 2 at the discharge end, a rotatable material dividing guide block 4 is provided in the trough body at the discharge end of the spiral chute 2, and a rotating motor 5 corresponding to the material dividing guide block 4 is provided on the outer side of the discharge end of the spiral chute 2. The output of the motor drives the material dividing guide block to swing in the trough body, thereby separating the concentrate and tailings of the material.

[0012] The material distribution guide block 4 is approximately triangular, with its tip located on the incoming material side, and the connection end with the rotating motor 5 is close to the side of the receiving trough 3. A longitudinally distributed material guide plate 8 is connected to the upper surface of the material distribution guide block 4, and a tip is provided on the thickness end surface of one side of the material guide plate 8, and its tip is located on the incoming material side.

[0013] A downward-illuminating camera 6 is installed on the bottom outer wall of the spiral chute 2 above the material distribution guide block 4, and a control module (not shown in the figure) is arranged on the outer side of the spiral chute 2. The control module is a computer, which forms an electrical signal control coordination with the rotating motor 5 and the camera 6 through unshown wires.

[0014] A step 3a is provided in the receiving trough 3, on which a vertically distributed partition 7 is installed, and the upper end of the partition 7 extends upward for a distance from the bottom surface of the trough body at the discharge end of the spiral chute 2. The receiving trough 3 is divided into a concentrate trough a and a tailings trough b by the partition 7.

[0015] The color difference of minerals collected by the camera is fed back to the control module. The control module controls the motor output to drive the material distribution guide block to swing to the appropriate position, thereby diverting the mineral materials sliding down the spiral chute, so that the concentrate can fall into the concentrate trough, and the tailings fall into the tailings trough.
