Description

Technical Field

[0001] This utility model relates to the field of ore recovery technology, specifically to a magnetic separation equipment for recovering tungsten from copper-sulfur tailings. Background Technology

[0002] Tungsten is an irreplaceable basic material for the national economy and modern national defense, and is an important strategic resource. It is widely used in important fields such as aerospace, machinery manufacturing, and defense industry. Therefore, the country attaches great importance to the development and utilization of tungsten resources. Existing technologies for tungsten ore recovery equipment typically use magnetic separators.

[0003] The core principle of a magnetic separator is to attract magnetic minerals with magnetic force to achieve separation. However, existing magnetic separators lack a material distribution function during use. When tailings are transported to the magnetic separator, they tend to accumulate in one position on the magnetic roller, resulting in a small portion of the magnetic minerals on the upper layer not being adsorbed, leading to poor screening effect. Therefore, a copper-sulfur tailings magnetic separation and tungsten beneficiation equipment is proposed to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a copper-sulfur tailings magnetic separation and tungsten beneficiation equipment, which has advantages such as improved screening effect. It solves the problem that existing magnetic separators lack material distribution function during use, and tailings tend to accumulate in one position on the magnetic roller when transported to the magnetic separator, resulting in a small amount of magnetic minerals on the upper layer not being adsorbed and poor screening effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a copper-sulfur tailings magnetic separation and tungsten beneficiation equipment, comprising a frame, a drive motor fixedly installed on the outside of the frame, and a magnetic separation roller rotatably installed on the inside of the frame. A belt conveyor is provided on one side of the frame, and a material distribution mechanism is provided above the magnetic separation roller.

[0006] The material distribution mechanism includes a support frame installed on the top of the machine frame and a guide plate installed on the top of the support frame. A first partition and a second partition are fixedly installed on the outer wall of the guide plate, and a connecting rod is movably inserted between the first partition and the second partition. An electric push rod is provided at one end of the connecting rod. Multiple material distribution plates are fixedly installed on the outer wall of the connecting rod. The multiple material distribution plates are equidistantly distributed along the connecting rod and are located between the first partition and the second partition.

[0007] Furthermore, one end of the magnetic separator roller is fixedly installed to the output shaft of the drive motor, and a collection hopper is fixedly installed on the side of the frame away from the belt conveyor.

[0008] Furthermore, a scraper is fixedly installed on the side of the collecting hopper near the magnetic separator roller, the scraper is in contact with the outer wall of the magnetic separator roller, and a discharge port is provided at the bottom of the collecting hopper.

[0009] Furthermore, a baffle is fixedly installed at the top edge of the belt conveyor away from the frame, and the baffle corresponds to the magnetic separation roller.

[0010] Furthermore, the guide plate is inclined downward at one end near the belt conveyor and corresponds to the top of the magnetic separator roller.

[0011] Furthermore, a mounting bracket is fixedly installed on the outer wall of the guide plate, the electric push rod is fixedly installed on the outside of the mounting bracket, and the connecting rod is fixedly connected to the output shaft of the electric push rod.

[0012] Furthermore, a sleeve is fixedly installed on the side of the second partition away from the first partition, and the end of the connecting rod away from the electric push rod extends into the sleeve.

[0013] Furthermore, a slider is fixedly connected to one end of the connecting rod located inside the sleeve, and the slider slides in contact with the inner wall of the sleeve.

[0014] Compared with the prior art, this utility model provides a magnetic separation equipment for recovering tungsten from copper-sulfur tailings, which has the following beneficial effects:

[0015] This copper-sulfur tailings magnetic separation equipment for tungsten ore beneficiation uses a feeder to transport tungsten-containing copper-sulfur tailings to a guide plate. The guide plate then guides the tailings onto the magnetic separation roller. An electric push rod moves a connecting rod left and right, which in turn moves multiple distribution plates synchronously. The movement of these plates disperses the tailings on the guide plate, causing them to fall onto the magnetic separation roller. The cooperation between the guide plate and the distribution plates buffers the fall of the tailings, reducing accumulation and ensuring that the magnetic separation roller efficiently adsorbs the magnetic minerals in the tailings. This improves screening efficiency and enhances practicality. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 The copper-sulfur tailings magnetic separation and tungsten beneficiation equipment in this embodiment includes a frame 1, a drive motor 2 fixedly installed on the outside of the frame 1, and a magnetic separation roller 3 rotatably installed on the inside of the frame 1. One end of the magnetic separation roller 3 is fixedly installed with the output shaft of the drive motor 2, and a belt conveyor 4 is provided on one side of the frame 1.

[0023] It should be noted that a hopper 5 is fixedly installed on the side of the frame 1 away from the belt conveyor 4, and a scraper 6 is fixedly installed on the side of the hopper 5 close to the magnetic separator 3. The scraper 6 is in contact with the outer wall of the magnetic separator 3, and a discharge port 7 is provided at the bottom of the hopper 5.

[0024] Understandably, by starting the drive motor 2 to drive the magnetic separator 3 to rotate clockwise (on one side of the collection hopper 5), the tungsten-copper-sulfur tailings are conveyed to the magnetic separator 3 by the feeder, so that the magnetic separator 3 adsorbs the magnetic minerals in the tailings. When passing the scraper 6, the scraper 6 will scrape the magnetic minerals away from the magnetic separator 3 and make them fall into the collection hopper 5. The tungsten ore and other non-magnetic minerals will slide down the surface of the magnetic separator 3 onto the belt conveyor 4. The belt conveyor 4 will transport the tungsten ore and other non-magnetic minerals to the next process for fine selection.

[0025] It should be added that a baffle 18 is fixedly installed at the top edge of the belt conveyor 4 away from the frame 1. The baffle 18 corresponds to the magnetic separation roller 3 and plays a role in preventing the minerals that slide onto the belt conveyor 4 from falling off.

[0026] In this embodiment, a material distribution mechanism is provided above the magnetic separator roller 3. The material distribution mechanism includes a support frame 8 installed on the top of the frame 1 and a guide plate 9 installed on the top of the support frame 8. The guide plate 9 is inclined downward at one end near the belt conveyor 4 and corresponds to the top of the magnetic separator roller 3. A first partition 10 and a second partition 11 are fixedly installed on the outer wall of the guide plate 9. A connecting rod 14 is movably inserted between the first partition 10 and the second partition 11. An electric push rod 13 is provided at one end of the connecting rod 14. A plurality of material distribution plates 15 are fixedly installed on the outer wall of the connecting rod 14. The plurality of material distribution plates 15 are equidistantly distributed along the connecting rod 14 and are located between the first partition 10 and the second partition 11.

[0027] The guide plate 9 is fixedly mounted with a mounting bracket 12, the electric push rod 13 is fixedly mounted on the outside of the mounting bracket 12, and the connecting rod 14 is fixedly connected to the output shaft of the electric push rod 13.

[0028] It should be noted that a sleeve 16 is fixedly installed on the side of the second partition 11 away from the first partition 10. The end of the connecting rod 14 away from the electric push rod 13 extends into the sleeve 16. A slider 17 is fixedly connected to the end of the connecting rod 14 inside the sleeve 16. The slider 17 slides with the inner wall of the sleeve 16, which plays a guiding role and improves the stability of the structure.

[0029] The working principle of the above embodiments is as follows:

[0030] In operation, tungsten-copper-sulfur tailings are conveyed to guide plate 9 via a feeder. Guide plate 9 guides the tailings to magnetic separator roller 3. By activating electric push rod 13, connecting rod 14 moves left and right, which in turn moves multiple distribution plates 15 synchronously. The movement of the distribution plates 15 disperses the tailings on guide plate 9, causing them to fall onto magnetic separator roller 3. The cooperation between guide plate 9 and distribution plates 15 buffers the fall of tailings, reduces accumulation, and ensures that magnetic separator roller 3 efficiently adsorbs magnetic minerals in the tailings. When passing through scraper plate 6, scraper plate 6 scrapes the magnetic minerals away from magnetic separator roller 3, causing them to fall into collection hopper 5. Tungsten ore and other non-magnetic minerals slide down the surface of magnetic separator roller 3 onto belt conveyor 4. Belt conveyor 4 transports tungsten ore and other non-magnetic minerals to the next process for fine separation.

[0031] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
