Description

Technical Field

[0001] This utility model belongs to the field of tailings treatment technology, specifically relating to an integrated tailings cleaning and screening device. Background Technology

[0002] Tailings refer to the waste residue discharged by mining enterprises after mineral processing. They are mostly discharged in the form of slurry, and the output is enormous. Currently, the main methods for tailings treatment include landfill, surface stockpiling, damming for stockpiling, and use as building materials after treatment. Among these, landfill and stockpiling remain the most common methods, resulting in extremely low utilization rates. Tailings typically contain residual valuable minerals, incompletely dissociated mineral particles, and large amounts of sludge, impurities, and chemical residues. To recover valuable components, reduce resource waste, mitigate environmental risks (such as heavy metal leaching and dust pollution), and meet environmental emission or comprehensive utilization requirements (such as building material production and filling of mined-out areas), efficient and thorough washing of tailings (removing attached sludge, chemical residues, soluble salts, etc.) is a crucial pretreatment step.

[0003] Currently, tailings cleaning and treatment largely rely on single washing equipment (such as drum washers and trough washers). However, existing technologies have significant drawbacks: First, such equipment often only performs a single rinse or scrub, making it difficult to thoroughly remove highly adhesive or tightly bound fine mud and residual agents, resulting in "incomplete cleaning in one go," affecting recovery rates and the quality of subsequent products. Second, existing washing equipment generally lacks the function of efficient "draining" and "screening" during or immediately after washing. This leads to the slurry being directly discharged or entering subsequent stages without effective solid-liquid separation (draining) and particle size classification (screening). Slurry with high water content and mixed mud and sand easily causes blockage of downstream screening equipment, significantly reducing screening efficiency and accuracy.

[0004] Therefore, there is an urgent need to provide a cleaning device that can thoroughly clean tailings and then drain and screen them after cleaning. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, an integrated tailings cleaning and screening device is provided, which solves the problems of incomplete tailings cleaning and the inability to drain and screen tailings after cleaning in existing technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tailings washing and screening integrated equipment includes:

[0008] A spiral cleaning unit includes a first cleaning tank and a propeller blade rotatably disposed within the first cleaning tank;

[0009] A waterwheel-type cleaning unit is connected to the spiral cleaning unit. The waterwheel-type cleaning unit includes a second cleaning tank. A screening component for cleaning and screening tailings is rotatably installed in the second cleaning tank, and the cleaned tailings are sent to the next process through the screening component.

[0010] The above structural design allows for multi-stage cleaning of tailings by setting up spiral cleaning units and waterwheel cleaning units, ensuring thorough cleaning. At the same time, the waterwheel cleaning unit is equipped with a screening component to drain and screen the tailings before discharge after secondary cleaning.

[0011] Preferably, the first cleaning tank and the second cleaning tank are connected, and the height of the first cleaning tank is higher than that of the second cleaning tank.

[0012] The above structural design allows tailings that have undergone a first cleaning in the first cleaning tank to be directly fed into the second cleaning tank for a second cleaning via a propeller blade. The entire process of cleaning the two cleaning steps is automated, resulting in a more thorough cleaning of the tailings.

[0013] Preferably, the spiral cleaning unit further includes a first rotating shaft and a first connecting component disposed on the first rotating shaft, wherein the propeller blades are fixedly connected to the first connecting component.

[0014] Preferably, the screening and washing assembly includes a second rotating shaft and a second connecting assembly disposed on the second rotating shaft. The end of the second connecting assembly is provided with a plurality of material receiving grooves, and the material receiving grooves are arranged in a ring.

[0015] With the above structural design, several feeding troughs are arranged in a ring structure, similar to a waterwheel structure. Therefore, when the feeding troughs rotate, they can not only collide and rub against the tailings to achieve secondary cleaning, but also automatically collect the tailings. After rotating to a certain position, the tailings are automatically poured out and enter the conveying device of the next process.

[0016] Preferably, the first and second rotating shafts are coaxial and are driven to rotate by a motor located on one side.

[0017] The above structural design simplifies the equipment and reduces costs, and the motor power can be selected according to requirements.

[0018] Preferably, the material feeding trough is inclined and has a detachable screen inside, and the adjacent material feeding troughs are connected by baffles on their outer sides.

[0019] With the above structural design, the lower trough can automatically pick up material when the material trough rotates. After picking up the material, it rotates away from the second washing trough and is automatically drained and screened through a screen, thus realizing the integrated operation of washing, draining and screening. At the same time, the baffle can limit the discharge of tailings when the material trough rotates to a certain angle, preventing the tailings from spilling out.

[0020] Preferably, the second cleaning tank is provided with a guide plate on one side of the rotation direction of the material receiving tank, and the guide plate is provided with upwardly extending limiting plates on both sides. The guide plate is connected to the conveying device of the next process to send out the cleaned tailings.

[0021] Preferably, the first cleaning tank is provided with a shell on top and a feed inlet at the front end.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. This utility model performs multi-stage cleaning of tailings by setting up a spiral cleaning unit and a waterwheel cleaning unit to ensure thorough cleaning of tailings. At the same time, the waterwheel cleaning unit is equipped with a screening component to drain and screen the tailings before discharge after secondary cleaning. Therefore, it not only improves the cleaning effect of tailings, but also has the functions of draining and screening, thus improving the efficiency of tailings treatment.

[0024] 2. Based on the working principle of a waterwheel, the waterwheel-type cleaning unit of this utility model can not only perform secondary cleaning by colliding and rubbing the tailings when rotating, but also automatically pick up the material and automatically drain and screen it through the screen, thus realizing the integrated operation of cleaning, draining and screening. After the cleaning tank rotates to a certain position, it can automatically pour out the tailings and enter the next process. Attached Figure Description

[0030] Please see Figure 1 A tailings cleaning and screening integrated device includes a spiral cleaning unit 1 and a waterwheel-type cleaning unit 2. The spiral cleaning unit 1 includes a first cleaning tank 1a and a propeller blade 1b rotatably disposed within the first cleaning tank 1a. The propeller blade 1b rotates to stir and clean the tailings within the first cleaning tank 1a while simultaneously propelling the tailings forward. An outer shell is provided above the first cleaning tank 1a, and a feed inlet is located at the front end. The waterwheel-type cleaning unit 2 is connected to the spiral cleaning unit 1 to perform continuous two-stage cleaning of the tailings. The waterwheel-type cleaning unit 2 includes a second cleaning tank 2a, within which a screening assembly 2b is rotatably disposed to clean and screen the tailings. The screen assembly 2b then transports the cleaned tailings to the next process. Based on the working principle of a waterwheel, the waterwheel-type cleaning unit 2, while rotating, performs friction cleaning on the tailings within the second cleaning tank 2a and loads the tailings into the screening assembly 2b. During rotation, the tailings are drained and screened before being automatically discharged.

[0031] The first cleaning tank 1a and the second cleaning tank 2a are connected, and the height of the first cleaning tank 1a is higher than that of the second cleaning tank 2a. In this embodiment, the bottom of both the first cleaning tank 1a and the second cleaning tank 2a are provided with structures such as drain outlets and sewage outlets, which are conventional technologies in the art and therefore will not be described in detail.

[0032] The spiral cleaning unit 1 further includes a first rotating shaft 1c and a first connecting component 1d disposed on the first rotating shaft 1c. The propeller blade 1b is fixedly connected to the first connecting component 1d. The first connecting component 1d serves to fix and support the propeller blade 1b. Due to the large resistance during tailings cleaning and conveying, the first connecting component 1d is staggered to improve its stability.

[0033] The screening and washing assembly 2b includes a second rotating shaft (not shown in the figure) and a second connecting assembly 21b disposed on the second rotating shaft. The end of the second connecting assembly 21b is provided with a plurality of material picking grooves 22b, and the material picking grooves 22b are arranged in a ring around the second rotating shaft to form a waterwheel-type structure.

[0034] In this embodiment, the first rotating shaft 1c and the second rotating shaft are coaxial and are driven to rotate by a motor located on one side.

[0035] Furthermore, the feeding trough 22b is inclined and has a detachable screen 23b inside. Adjacent feeding troughs 22b are connected by baffles 24b on their outer sides. The second washing tank 2a has a guide plate 2c on one side of the feeding trough 22b's rotation direction, and upward-extending limiting plates 25b are provided on both sides of the guide plate 2c. The guide plate 2c connects to the conveying device of the next process to deliver the washed tailings. The baffles 24b, limiting plates 25b, and guide plates 2c ensure that the tailings poured out of the feeding trough 22b enter the next process in a designated direction.

[0036] The working principle of this utility model is as follows:

[0037] When cleaning tailings, the tailings are first poured into the first cleaning tank 1a through the feed inlet of the spiral cleaning unit 1. The tailings are then agitated and cleaned in the first cleaning tank 1a by the rotation of the propeller blades 1b. Simultaneously, the tailings are fed into the second cleaning tank 2a along the first cleaning tank 1a. At this time, the receiving trough 22b rotates under the drive of the second rotating shaft. The receiving trough 22b, entering the second cleaning tank 2a, contacts and rubs against the tailings, and the tailings rub against each other, completing the secondary cleaning of the tailings. Simultaneously, the receiving trough 22b automatically scoops in the tailings and automatically rotates to detach from the second cleaning tank 2a. Because a screen 23b is installed inside the receiving trough 22b, preliminary screening and drainage of the tailings can be performed after receiving the material. When the receiving trough 22b rotates to a certain position, it automatically pours out the tailings inside and proceeds to the next process. Therefore, this invention can perform multi-stage cleaning of tailings, ensuring the effectiveness of the tailings cleaning process. Meanwhile, the water-wheel type cleaning unit 2 can simultaneously clean the tailings, drain the tailings, and perform preliminary screening.

[0038] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
