Description

Technical Field

[0001] The present invention relates to the field of tailings treatment, in particular to a crushing device for tailings treatment. Background Art

[0002] Tailings: After the original ore is sorted, its main components are concentrated in the concentrate. Some ore is neutralized to recover minor components or other associated metals. The remaining product, which contains very low levels of useful components, is called final tailings. It should be noted that tailings still contain useful components that are difficult to extract with modern technology, but they may become reusable raw materials in the future.

[0003] Patent No. CN222984463U proposes a tailings crushing device, comprising a housing housing two crushing rollers that rotate in opposite directions. A feed pipe, located between the two crushing rollers, is connected to the upper end of the housing. The feed pipe includes a material guide structure that distributes material along the axial direction of the crushing rollers to different positions on the rollers. This prevents excessive material from accumulating in the middle of the crushing rollers, which would otherwise cause heavy loads there and severe wear on the roller surface, shortening the roller's service life.

[0004] In this patent, although the material can be transported to different locations for crushing, a lot of dust will be generated during the tailings crushing process. However, this patent does not process the dust, which makes it easy for the dust to drift to the outside, which can easily cause environmental pollution. It is not convenient for the crushing of the tailings and reduces the crushing efficiency of the tailings.

In addition, the gap formed by the grinding roller and the grinding trough is in a state of wide at the top and narrow at the bottom. In this way, the tailings can be gradually crushed, thereby facilitating the full crushing of the tailings and improving the crushing efficiency of the tailings. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In this embodiment, when the tailings are crushed, the tailings are transported to the crushing box 1 through the feed hopper 2. At this time, under the movement of the first drive motor 62, the meshing movement of the two gears 61 is coordinated, so that the two crushing rollers 3 can be driven to rotate in opposite directions, and the tailings can be crushed by the crushing rollers 3. When the gear 61 rotates, the eccentric rotation of the first connecting rod 71 is driven at the same time, and the first connecting rod 71 can pull the reciprocating swing of the second connecting rod 72, and the second connecting rod 72 drives the reciprocating swing of the nozzle 4 and the nozzle 5.

In this way, when the tailings are fed through the feed hopper 2, they will fall through between the two nozzles 4, so that the tailings will not fall onto the nozzle 4 and cause impact damage.

[0034] Example 2:

[0035] Please refer to Figure 4 , two cover plates 9 are slidably provided at the top of the feed hopper 2, and a material guide trough 10 is inclined at the top of the two cover plates 9.

The two sliders 121 drive the two adjustment plates 11 to move in the opposite direction, thereby driving the two cover plates 9 to move in the opposite direction. During the movement of the two cover plates 9, the opening size of the feed hopper 2 can be adjusted, thereby adjusting the feeding amount of the tailings, avoiding excessive feeding of the tailings and resulting in incomplete crushing, thereby improving the crushing efficiency of the tailings. Efficiency, and the setting of the guide chute 10 can facilitate the guiding of the tailings and the transportation of the tailings to the feed hopper 2. When the tailings feeding is completed, the two cover plates 9 will completely close the feed hopper 2, so as to prevent dust from drifting to the outside through the feed hopper 2. An accordion cover is provided in the chute 122, one end of the accordion cover is connected to the chute 122, and the other end is connected to the slider 121, which is used to close the chute 122, thereby facilitating the protection of the structure in the chute 122 and preventing dust from adhering to the material and affecting its use.

[0037] Example 3:

[0038] Please refer to Figure 5 A support base 13 located below the crushing roller 3 is fixed in the crushing box 1, and a grinding groove 14 is opened at the top of the support base 13. A grinding roller 15 is rotatably connected in the grinding groove 14. The bottom end of the support base 13 is provided with a driving assembly 16 for driving the grinding roller 15 to move.

The support seat 13 is in a state of high sides and low middle, so that the crushed tailings can fall into the grinding trough 14, and then under the movement of the third drive motor 162, the grinding roller 15 is driven to rotate, so that the grinding roller 15 can grind and crush the tailings again, and the gap formed by the grinding roller 15 and the grinding trough 14 is in a state of wide at the top and narrow at the bottom, so that the tailings can be gradually crushed, thereby facilitating the full crushing of the tailings and improving the crushing efficiency of the tailings.

[0040] The working principle of the crushing device for tailings treatment provided by the present invention is as follows:

[0041] When the tailings are fed through the feed hopper 2, the movement of the second drive motor 124 drives the rotation of the bidirectional screw rod 123, and the bidirectional screw rod 123 drives the two sliders 121 to move in the opposite direction. The two sliders 121 drive the two adjustment plates 11 to move in the opposite direction, thereby driving the two cover plates 9 to move in the opposite direction. During the movement of the two cover plates 9, the opening size of the feed hopper 2 can be adjusted, thereby adjusting the feeding amount of the tailings, avoiding excessive feeding of tailings and incomplete crushing, thereby improving the crushing efficiency of the tailings. In addition, the setting of the guide chute 10 can facilitate the guiding of the tailings and facilitate the transportation of the tailings into the feed hopper 2. When the tailings feeding is completed, the two cover plates 9 completely close the feed hopper 2, which can prevent dust from drifting to the outside through the feed hopper 2. At this time, under the movement of the first drive motor 62, the meshing movement of the two gears 61 is coordinated, which can drive the two crushing rollers 3 to rotate in opposite directions, and the crushing rollers 3 can be used to crush the tailings. During the rotation of the gear 61, the first connecting rod 71 is driven at the same time. By eccentric rotation, the first connecting rod 71 can pull the second connecting rod 72 to swing back and forth, and the second connecting rod 72 drives the nozzle 4 and the nozzle 5 to swing back and forth. Then, under the operation of the water pump 83, the water in the water supply tank 81 is pumped out, and then transported to the nozzle 4 through the three-way pipe 84 and the hose 85, and then sprayed out through the nozzle 5 swinging, so that the dust in the crushing box 1 can be sprayed to reduce dust, thereby reducing the dust dispersion, facilitating the crushing of the tailings, and improving the crushing efficiency of the tailings. When the tailings pass through the crushing roller 3 After being crushed, it falls onto the support seat 13, which is in a state of high sides and low middle, so that the crushed tailings can fall into the grinding trough 14, and then under the movement of the third drive motor 162, the grinding roller 15 is driven to rotate, so that the grinding roller 15 can grind and crush the tailings again, and the gap formed by the grinding roller 15 and the grinding trough 14 is in a state of wide at the top and narrow at the bottom, so that the tailings can be gradually crushed, thereby facilitating the full crushing of the tailings and improving the crushing efficiency of the tailings.
