Description
Technical Field
[0001] The utility model relates to the technical field of tailings screening, and particularly relates to an aggregate device for fine-grained tailings grading and dewatering screens. Background Art
[0002] A dewatering screen is a mining mechanical equipment used for dehydration, de-sludging, and de-medium separation. The working principle of the dewatering screen is based on the vibration generated by a vibration motor, which makes the screen box perform periodic reciprocating motion along a straight track. Materials enter the screen box from the feeding end. Under the action of vibration, the moisture smaller than the screen holes falls through the screen holes, while the solid particles larger than the screen holes continue to move forward to the discharging end. In this way, the dewatering screen realizes the functions of material grading and dehydration. The dewatering screen is widely used in occasions such as sand washing in sand and gravel plants, coal slime recovery in coal preparation plants, and dry discharge of tailings in ore dressing plants. It can effectively remove the moisture in the muddy water mixture and separate the solid particles, thereby improving the dryness and cleanliness of the materials. The design of the dewatering screen usually includes components such as a vibration motor, a screen box, a vibration damping device, a screen mesh, and a frame. According to different industrial requirements, the dewatering screen can have different models and specifications to meet the requirements of different processing capacities and material characteristics.
[0003] However, the existing dewatering screens often encounter the following problems when in use: When dealing with fine-grained tailings, to ensure the grading and dewatering efficiency of the fine-grained tailings, water is sprayed on the screen surface of the grading and dewatering screen and the inclination angle of the screen surface is increased. The feeding end is at the lower position of the screen surface with a large amount of water, and the discharging section is at the higher position of the screen surface with a smaller amount of water. The slope of the under-screen aggregate funnel is fixed, and tailings are likely to accumulate on one side of the discharging end. Tailings grading is at the end of the ore dressing production process, and the temperature of the pulp is relatively low in winter, which is likely to freeze and affect subsequent production and processing, reducing production efficiency.

[0039] Such as Figures 1 - 3As shown in the figure, a fine-grained tailings grading and dewatering screen aggregate device includes: an aggregate main body 1, a feed opening 2, a discharge port 3, a weight reduction tank 4, and a corrugated side conveyor belt 5; a roller body housing 6, a roller main body 7, a current collector 8, an insulating housing 9, an electric heating tube 10, a plug hole 11, and bristles 12. The aggregate main body 1 is erected on the ground, providing support and a structural foundation for the entire device. The feed opening 2 is opened at the top of the aggregate main body 1, and the discharge port 3 is opened at the bottom of the aggregate main body 1. There are two groups of weight reduction tanks 4, and the two groups of weight reduction tanks 4 are respectively opened on both sides of the aggregate main body 1, which helps to reduce the overall weight of the device and plays a role in balance and stability at the same time. The corrugated side conveyor belt 5 is installed in the feed opening 2. The roller body housing 6 is located below one end of the corrugated side conveyor belt 5. The roller main body 7 penetrates through the central axis of the roller body housing 6, and the roller main body 7 penetrates through the inner wall of the aggregate main body 1.
[0040] In this embodiment, as Figure 3 shown, the current collector 8 is installed at one end of the roller main body 7. The current collector 8 is electrically connected to the power supply box 13. The current collector 8 is installed at one end of the roller main body 7 and is electrically connected to the power supply box 13, responsible for power transmission. There are two insulating housings 9, and the two insulating housings 9 are respectively arranged at both ends of the roller body housing 6. At least four electric heating tubes 10 respectively penetrate through the insulating housings 9. The design of the electric heating tubes 10 can be used to heat the roller body housing 6 in a low-temperature environment to prevent the material from freezing and ensure the continuous operation of the equipment. The plug holes 11 are distributed on the outer surface of the roller body housing 6. The electric heating tubes 10 are electrically connected to the current collector 8, and the electric heating tubes 10 are in contact with the inner wall of the roller body housing 6. There are several bristles 12, and several bristles 12 are inserted into the plug holes 11. The bristles 12 are made of PA46 nylon. Using bristles 12 made of PA46 nylon has good wear resistance and flexibility, and has a relatively high melting point, extending the service life of the equipment. The power supply box 13 is installed on the other side of the aggregate main body 1, providing power for the entire device.
[0041] Preferably, both ends of the first roller shaft 51 penetrate through the inner walls on both sides of the aggregate main body 1. The second roller shaft 52 is located above the discharge port 3, and the two cooperate to realize the conveying of materials. The ribbed drive belt 53 is sleeved on the first roller shaft 51 and the second roller shaft 52.

When in use, the device is installed below the classification and dehydration screen. The motor 54 is started, and the output end of the motor 54 rotates to drive the second roller shaft 52. The rotation of the second roller shaft 52 drives the ribbed conveyor belt 53 and the first roller shaft 51 to start conveying materials. After the classification and dehydration screen feeds the materials, the speed of the corrugated rib conveyor belt is adjusted according to the amount of tailings under the screen to ensure that the tailings are transported out in time. The rotation speed of the roller body 7 is adjusted according to the discharging effect of the tailings to ensure that the discharging point of the tailings is located on the steep pulp, and is carried into the funnel outlet by the pulp. When the temperature is lower than 0 °C, the heating function is turned on. The power supply box 13 is started, and the power supply box 13 conducts electricity to the current collector 8. Then, the current collector 8 transmits the current to the four electric heating tubes 10 respectively. The electric heating tubes 10 generate heat and conduct the heat to the roller body housing 6, and then the roller body housing 6 conducts the heat to the bristles 12. After the material falls and contacts the roller body housing 6 and the bristles 12, the roller body housing 6 will roll, and the material will be scattered and receive some heat at the same time to prevent the tailings under the screen from freezing, and finally discharged from the discharge port 3.
