Description

Technical Field

[0001] This invention relates to a mineral processing device and method, specifically a box-type linear suspension vibration mineral processing device and method, belonging to the technical field of mineral processing equipment and methods. Background Technology

[0002] With the development of science and technology and the economy, the demand for various mineral products is increasing. In addition, the environmental protection requirements for mineral processing technology are also getting higher and higher. Especially when mineral processing is carried out in the field, chemical beneficiation cannot be used due to environmental protection considerations. Only gravity separation or magnetic separation can be used.

[0003] Currently, gravity separation equipment used in the mineral processing industry, such as jigs, centrifugal concentrators, spiral sluices, and shaking tables, all have certain problems, such as difficulty in field use, inability to arbitrarily assemble and expand production, small processing capacity, low recovery rate, unstable operating conditions, large human interference factors, high power consumption, complex installation and maintenance, and high noise.

[0004] Therefore, it is necessary to develop a mineral processing device that is both environmentally friendly and convenient to use in the field, achieving stable operation and high recovery efficiency to solve this problem. Summary of the Invention

[0005] The present invention aims to solve a series of problems existing in the technology of existing gravity separation equipment, and to provide a box-type linear suspension vibration mineral processing device and mineral processing method.

[0006] To solve the above problems, the technical solution adopted by the present invention is as follows: A box-type linear suspension vibratory mineral processing device is characterized by using a shipping container as the equipment carrier. A raw material feed hopper is mounted on the top of the container, and a high-frequency vibrating host and a flat bed frame are suspended inside the container and connected to each other. A trough-type bed plate is mounted on the flat bed frame. A feed equalizer connected to the raw material feed hopper is mounted at the feed end of the trough-type bed plate, and a cutter for cutting and diverting the slurry is mounted at the discharge end of the trough-type bed plate. One end of the cutter is adapted to the discharge end of the trough-type bed plate to form a concentrate discharge channel, and the other end of the feed equalizer is adapted to a sloping plate installed on the flat bed frame to form a tailings discharge channel.

[0007] Furthermore, the planar bed frame is a multi-layer planar bed frame, and the number of the grooved bed boards matches the number of layers of the planar bed frame; the grooved bed board is a box-groove structure, with three sides folded up to form a deep groove, leaving one short side laid flat as the discharge end; the tail of the discharge end has a lower-step guide plate, which is lower than and parallel to the surface of the discharge end.

[0008] Furthermore, the material cutter has a T-shaped flow cutter, which is composed of a top horizontal panel and a bottom vertical rib perpendicular to the horizontal panel. One end of the horizontal panel overlaps the lower step flow guide plate of the trough bed plate and leaves a certain flow guide gap with it. The other end of the horizontal panel overlaps the material feeding inclined plate.

[0009] Furthermore, the cutter also includes an angle iron beam and an adjusting screw. The angle iron beam is fixed on the flat bed frame, and the adjusting screw is used to adjust the height of the T-shaped cut-off plate. Its upper end is connected to the angle iron beam, and its lower end is fixed to the horizontal panel of the T-shaped cut-off plate.

[0010] Furthermore, the flat bed frame is suspended in an adjustable manner on the crossbeam at the top of the container by two sets of suspension components, one in front and one behind. The two sets of suspension components have the same structure, each including a lifting rod, a pulley, and a fixed angle iron. The upper end of the lifting rod is connected to the crossbeam, and the lower end is connected to the pulley installed on the fixed angle iron. The fixed angle iron is fixed to one side of the flat bed frame. The suspension method of the high-frequency vibration host is the same as that of the flat bed frame, including a fixed angle iron fixed to the outside of the high-frequency vibration host box, a pulley installed on the fixed angle iron, and a lifting rod with the upper end connected to the crossbeam and the lower end connected to the pulley.

[0011] Furthermore, the raw material feed hopper is connected to the feed equalizer via a feed branch pipe. The feed equalizer has a feed hole at the top to connect to the feed branch pipe and a discharge hole at the bottom for distributing material onto the surface of the trough-type bed board.

[0012] Furthermore, the high-frequency vibration host and the flat bed frame are connected by a connector suspended inside the container. The connector is equipped with pulleys, and the crossbeam at the top of the container is connected to the pulleys on the connector via a lifting cable.

[0013] Furthermore, a mineral concentrate feeding hopper is arranged below the bed surface of the trough-type bed plate. The feeding slope of the mineral concentrate feeding hopper is <15°. Its upstream inlet is located at the mineral concentrate feeding channel at the front end of the cutter, and its downstream outlet is connected to the mineral concentrate feeding pipe.

[0014] Furthermore, the container is also equipped with a tailings hopper on its inner side. The tailings hopper is located on the discharge side of the flat bed frame with a material-carrying inclined plate, and is used to connect with the tailings discharge channel. The installation angle of the inclined plate on the flat bed frame shall not be less than 15°.

[0015] A mineral processing method based on the above-described box-type linear suspension vibration mineral processing device is characterized by comprising the following steps: Step 1: Select the particle size of the slurry, adjust the mass ratio of water to ore in the slurry, and control the thickness of the stockpile; based on the selected slurry, adjust the slope of the bed, the oscillation frequency and stroke of the high-frequency vibrator, and the cutting gap of the cutter. Step 2: Start the high-frequency vibration host, adjust the frequency converter to the appropriate oscillation frequency, and the high-frequency vibration host drives the slotted bed board on the flat bed frame to swing horizontally back and forth through the connecting parts; Step 3: After the slurry is injected from the raw material feed tank, it is evenly distributed to each feeder through the feed branch pipe, and then evenly distributed on the feed end of the trough bed plate by the feeder. Step 4: Under the high-frequency uniform vibration of the high-frequency vibrating host, the slurry continuously moves from the feed end to the discharge end on the surface of the trough bed plate; Step 5: Under the action of buoyancy of the medium and the shear force generated by the reciprocating motion of the tank, the slurry continues to loosen and stratify according to density in the tank bed plate, with heavy minerals sinking to the bottom and light minerals floating on top. Step Six: When the stratified slurry moves to the cutter at the end of the trough bed plate, the cutter cuts the slurry layer into upper and lower layers from the cross section. The heavy minerals in the lower layer enter the cutter below through the lower step guide plate at the end of the trough bed plate, flow through the bottom surface of the T-shaped cutter plate to the concentrate discharge hopper, and finally collect and discharge through the concentrate discharge pipe. The light minerals in the upper layer flow from the top of the T-shaped cutter plate of the cutter to the feed inclined plate, and finally collect and discharge through the tailings discharge hopper.

[0016] Furthermore, in step one, the particle size of the slurry is 0.01-5.0 mm; the mass ratio of water to mineral sand in the slurry is 1-3:1; and the thickness of the stockpile is 10-35 mm.

[0017] This invention discloses a box-type linear suspension vibration mineral processing device, using a shipping container as the equipment carrier. It is suitable for field mineral processing, facilitating transportation, installation, and maintenance. It can be arbitrarily assembled for capacity expansion, effectively increasing slurry processing capacity and production output. The core functional components within the container employ a multi-layer planar bed frame suspension structure, ensuring stable operation, low resonance, and low noise. The suspension structure allows for adjustment of the bed surface slope according to different ore types and particle sizes. The designed cutter structure enables adjustable height and gap for layered cutting, transforming the traditional planar segmented cutting into upper and lower layered cutting, significantly improving mineral processing output and efficiency. This box-type linear suspension vibration mineral processing method, by pre-screening uniform particle sizes and adjusting the bed surface slope, vibration frequency, stroke, and cutter gap, can achieve ideal mineral processing results.

[0034] Example 2 This embodiment relates to a mineral processing method based on a box-type linear suspension vibrating mineral processing device as described in Embodiment 1, including the following mineral processing steps: Step 1: Select mineral slurry with a particle size of 0.01-5.0mm, adjust the mass ratio of water to mineral sand in the slurry to 1-3:1, and control the thickness of the stockpile layer to 10-35mm; Based on the selected slurry, adjust the slope of the bed surface, the oscillation frequency and stroke of the high-frequency vibrating host, and the height position of the cutter 9 to ensure a reasonable cutting gap. Step 2: Start the high-frequency vibration host 5. The high-frequency vibration host 5 drives the grooved bed board 8 on the flat bed frame 7 through the connector 6. Figure 5 The AB direction is shown as longitudinal horizontal reciprocating oscillation; Step 3: After the slurry is injected from the raw material feed tank 15, it is evenly distributed to each feeder 17 through the feed branch pipe 16, and then evenly distributed on the bed surface of the trough bed plate 8 at the feed end (A end) through the feeder 17.

Step 5: Under the action of buoyancy of the medium and the shear force generated by the reciprocating motion of the tank, the slurry continues to loosen and stratify according to density in the bed of the trough bed plate 8, with heavy minerals sinking to the bottom and light minerals floating on top. Step Six: When the stratified slurry moves to the cutter 9 at the end of the trough bed plate 8, the cutter 9 divides the slurry layer into upper and lower layers from the cross section. The heavy minerals in the lower layer enter the cutter 9 below through the lower step guide plate 81 at the end of the trough bed plate 8, flow through the bottom surface of the T-shaped cutter plate 91 to the concentrate discharge hopper 11, and finally collect and discharge through the concentrate discharge pipe 12.

This embodiment employs an upper and lower layer cutting method, increasing the output of minerals processed per hour from 1 ton to approximately 4 tons, with a recovery rate more than 40% higher. Furthermore, it eliminates the need for long-term on-site personnel during production. By pre-screening to ensure uniform particle size and adjusting the slope of the bed, the frequency of vibration, the stroke, and the gap of the cutter, ideal mineral processing results can be achieved.
