Description

Technical Field

[0001] This utility model belongs to the field of tungsten mining technology, and in particular relates to a ore beneficiation and fine separation device for tungsten mining. Background Technology

[0002] Tungsten ore is a mineral containing tungsten, mainly including scheelite and wolframite. Tungsten has a high melting point, high hardness, and high temperature resistance, making it a core raw material for manufacturing key materials such as high-temperature alloys, cemented carbides, and tungsten wire. It is widely used in aerospace, defense, and electronic information industries, and is very important for industrial development and national industrial security. Natural tungsten ore has a low tungsten content and is often mixed with gangue minerals, so the raw ore cannot meet industrial needs. Therefore, mineral processing equipment is used to separate and purify the tungsten by taking advantage of the differences in the physical properties of the minerals through crushing, flotation, and other processes, thereby increasing the tungsten grade and producing qualified tungsten concentrate. This lays the foundation for subsequent smelting and product manufacturing and is the key to the efficient utilization of tungsten resources.

[0003] However, in the existing mineral processing and fine separation equipment, materials tend to accumulate on the screen during use, which directly leads to a reduction in the effective screening area of ​​the screen, thereby reducing the overall screening efficiency and throughput, resulting in uneven particle size of the produced mineral processing products and affecting the quality of subsequent mineral processing operations. Utility Model Content

[0004] The purpose of this utility model is to provide a mineral processing and fine separation device for tungsten mining. By setting up a vibrating part, it solves the problem that in the existing mineral processing and fine separation devices, material tends to accumulate on the screen during use, which directly leads to a reduction in the effective screening area of ​​the screen, thereby reducing the overall screening efficiency and throughput, resulting in uneven particle size of the produced mineral processing products, and affecting the quality of subsequent mineral processing operations.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a ore beneficiation and fine separation device for tungsten ore mining, comprising a base, and further comprising: a vibrating part installed on the top of the base; a screening part installed on the vibrating part; the vibrating part comprising a vibrating assembly installed on the top of the base; and a driving assembly installed on the base; the vibrating assembly comprising a U-shaped bracket installed on the top of the base, wherein two telescopic rods are fixedly connected to the top inner wall and the bottom inner wall of the U-shaped bracket, and inverted T-blocks are fixedly connected between several telescopic rods; each of the telescopic rods is fitted with a spring on its outer wall, with the sides of the springs close to each other fixedly connected to the inverted T-blocks, and the sides of the springs far apart from each other fixedly connected to the U-shaped bracket. Next, a support member is provided on the top of the base; the inverted T-block is located inside the U-shaped bracket. The support member includes two support plates fixedly connected to the top of the base. Two hexagonal sliding rods pass through each of the two support plates. Several hexagonal sliding rods are slidably connected to the two support plates. The sides of the hexagonal sliding rods that are close to each other are fixedly connected to the U-shaped bracket. The outer walls of the hexagonal sliding rods are fitted with springs. The sides of the springs that are close to each other are fixedly connected to the U-shaped bracket. The sides of the springs that are close to each other are respectively fixedly connected to the two support plates. The two support plates are located on the left and right sides of the U-shaped bracket, respectively. The springs are located between the two support plates, ensuring that the inverted T-block drives the screening section to vibrate smoothly and at high frequency.

[0007] Furthermore, the screening section includes a support assembly mounted on an inverted T-block; and a screening assembly mounted on the support assembly.

[0008] Furthermore, the drive assembly includes a motor fixedly connected to the rear side of the inverted T-block. The output shaft of the motor is fixedly connected to a rotating shaft via a coupling. The front side of the rotating shaft passes through the inverted T-block and extends outward. The rotating shaft is rotatably connected to the inverted T-block. An eccentric block is fixedly connected to the outer wall of the rotating shaft. The eccentric block is located on the front side of the inverted T-block and provides the core vibration force source for the vibrating part. It is a key component for realizing screen vibration and preventing material accumulation.

[0009] Furthermore, the support assembly includes a support frame fixedly connected to the top of the inverted T-block, and a collection component is provided on the support frame; the support frame is located on top of the base, and the collection component includes a collection box fixedly connected to the inner wall of the bottom of the support frame; the collection box is located below the three-stage screen to achieve centralized collection of the screened raw materials and prevent fine materials from scattering.

[0010] Furthermore, the screening assembly includes a primary screen fixedly connected to the inner wall of the support frame, a secondary screen fixedly connected to the inner wall of the support frame, and a tertiary screen fixedly connected to the inner wall of the support frame; the right sides of the primary, secondary, and tertiary screens are all open, the openings of the primary, secondary, and tertiary screens are arranged crosswise, and the primary, secondary, and tertiary screens are inclinedly arranged on the support frame to achieve multi-particle-size grading and screening, thereby improving the fine separation accuracy of mineral processing.

[0011] This utility model has the following beneficial effects:

[0012] 1. By setting up a vibrating section, during the screening process, after the motor is started, the motor drives the eccentric block to rotate through the shaft and generates centrifugal force, which in turn causes the inverted T-block to shake. When the inverted T-block shakes, it squeezes several telescopic rods and spring 1 above and below, causing spring 1 to generate elastic force. At the same time, it squeezes several hexagonal sliding rods and spring 2 through the U-shaped bracket, causing spring 2 to deform and generate elastic force. Under the combined action of the elastic forces of spring 1 and spring 2, the shaking frequency of the inverted T-block is enhanced. Finally, the inverted T-block drives the primary screen, secondary screen and tertiary screen to shake together through the support frame. This can effectively reduce the accumulation of raw materials on the screen, avoid screen hole blockage, ensure the continuous and stable operation of screening, and improve the stability of the classification of raw materials of different particle sizes, thus improving the sorting quality.

[0013] 2. By setting up a screening section, raw materials are added from the top left side of the primary screen. With the help of the inclined screen design, the raw materials roll to the right on the primary screen. The raw materials that meet the aperture requirements of the primary screen fall into the secondary screen, the raw materials that meet the aperture requirements of the secondary screen then fall into the tertiary screen, and the raw materials that meet the aperture requirements of the tertiary screen finally fall into the collection box for collection. The raw materials that do not meet the corresponding aperture requirements and are blocked by the primary, secondary and tertiary screens respectively flow out through the openings on the right side of each screen and are collected. This can achieve multi-level separation of raw materials of different particle sizes, meet the classification needs of raw materials of different particle sizes, and improve the precision of raw material sorting.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
