Description

Technical Field

[0001] This utility model relates to the field of tailings treatment technology, and in particular to a tailings dry discharge and dewatering equipment. Background Technology

[0002] Dry tailings stacking technology, as an important means of green tailings treatment in mines, is widely used in the beneficiation processes of metallic and non-metallic mineral resources. Its main purpose is to effectively remove water from tailings slurry, achieving dry stacking and storage of tailings to reduce environmental pollution risks, while simultaneously recovering clean water for recycling within the mining area. Tailings dry stacking dewatering equipment, as the core equipment of this process, typically includes a feeding system, a vibrating screen mechanism, a dewatering unit, and a water collection system. Its overall performance directly affects the tailings dewatering efficiency and the stability of subsequent treatment.

[0003] Existing tailings dry discharge dewatering equipment mostly uses linear vibrating screens or high-frequency dewatering screens as the main screening components, utilizing mechanical vibration to separate free water from solid particles in the tailings slurry. The tailings slurry typically flows freely into the screen surface through the feed inlet. Due to the screen surface's angle, the material moves forward under the combined action of gravity and vibration force, gradually achieving solid-liquid separation during this movement. Some systems are equipped with hydrocyclones and thickeners to further improve dewatering efficiency. The overall structure is relatively compact and suitable for continuous operation.

[0004] However, existing tailings dry discharge dewatering equipment has defects in the structural design of the feeding section, lacking flow regulation and buffer structures. The tailings slurry directly impacts the screen surface without being slowed down, resulting in severe wear of the screen in the feeding section. This not only shortens the service life of the equipment but also increases maintenance costs and affects the continuous and stable operation of the dry discharge system. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a tailings dry discharge dewatering equipment, which aims to improve the existing structure's lack of flow regulation and buffer structure at the feed inlet and the serious wear of the feed section screen caused by direct impact of materials on the screen.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tailings dry discharge dewatering device, comprising a support frame, a frame fixedly connected to the upper surface of the support frame, a connecting block one fixedly connected to the inner wall of the frame, a fixing plate two fixedly connected to the upper surface of the connecting block one, a feed pipe fixedly connected to the upper surface of the fixing plate two, and an adjustment component provided inside the feed pipe;

[0007] The adjustment assembly includes a sliding plate one and a sliding plate two, both of which are disposed inside the feed pipe.

[0015] This utility model has the following beneficial effects:

[0016] In this invention, by setting an adjustment component inside the feed pipe, including a sliding plate one, a sliding plate two, and a reciprocating screw, the cross-sectional area of ​​the feed channel can be precisely adjusted according to the actual tailings slurry flow requirements, thereby achieving material flow control.

[0027] The regulating assembly includes a sliding plate 19 and a sliding plate 20, which are symmetrically arranged to form a variable channel, assisting in the precise control of tailings slurry flow. Both sliding plates 19 and 20 are located inside the feed pipe 9. A stepped buffer plate 16 is fixedly connected to the inner wall of the feed pipe 9. The stepped buffer plate 16 is used to reduce the falling speed and impact force of the tailings slurry, preventing the material from directly impacting the screen 6 and causing wear. A spiral guide plate 17 is fixedly connected to the inner wall of the feed pipe 9. The spiral guide plate 17 guides the tailings slurry to fall slowly along a spiral path, extending the buffer path.

A sealing strip 31 is fixedly connected to the outer wall of the sliding plate 19.

The motor 8 and the vibration motor 8 generate excitation force to make the screen 6 vibrate, which accelerates the removal of water from the tailings and improves the dewatering efficiency. The upper surface of the frame 3 is fixedly connected to the column 12, and the lower surfaces of the sliding plate 19 and the sliding plate 20 are slidably connected to the inner wall of the feeding plate 21. The feeding plate 21 is set below the feeding system to receive the buffered tailings and guide them to fall evenly onto the screen 6 to avoid concentrated impact. The outer wall of the reciprocating screw 18 is threaded to the inner wall of the feeding pipe 9, and the threaded rod 32 is threaded to the inner wall of the sliding rail 26. The outer wall of the connecting rod 12 is sleeved on the inner wall of the connecting rod 23.

[0029] Working Principle: When a tailings dry discharge dewatering device is needed, the tailings slurry first enters the device through the feed pipe 9. The feed pipe 9 contains a flow regulation component, which consists of a sliding plate 19, a sliding plate 20, and a reciprocating screw 18. The reciprocating screw 18 is threaded onto the inner walls of the sliding plates 19 and 20. Rotating the reciprocating screw 18 drives the sliding plates 19 and 20 to move up and down along the inner wall of the discharge plate 21, thereby changing the cross-sectional area of ​​the internal channel of the feed pipe 9 and regulating the tailings slurry flow rate. To avoid… The tailings slurry directly impacts the screen 6 at high speed. The inner wall of the feed pipe 9 is equipped with a stepped buffer plate 16 and a spiral guide plate 17. Under the guidance of the spiral guide plate 17, the tailings slurry slowly falls along the spiral path. The stepped buffer plate 16 disperses and slows down the falling speed, effectively reducing the impact of the material on the screen 6. The tailings slurry falls onto the screen surface through the feed plate 21. Under the synergistic effect of the flow regulation component and the buffer structure, the impact force in the feed section is significantly reduced, thereby slowing down the wear rate of the screen 6, improving the service life of the screen 6, and enhancing the stability of the whole machine operation and the continuity of dewatering treatment.

[0030] In addition, to achieve flexible adjustment of the screen angle 6, a connecting plate 13 and a connecting plate 28 are provided on the frame 3. A slide rail 24 is fixed on the upper surface of the connecting plate 13, and a slider 25 is slidably connected to the inner wall of the slide rail 24. The slider 25 is rotatably connected to the outer wall of the connecting plate 28 via a connecting rod 23. A slide rail 26 is provided on the lower surface of the connecting plate 28, and a slider 29 is slidably connected to the inner wall of the slide rail 26. The slider 29 is connected to the slider 25 via a connecting rod 22 to achieve vertical linkage. A threaded rod 32 is threadedly connected to the inner wall of the slide rail 26. Rotating the threaded rod 32 can drive the slider 29 to move in the vertical direction, thereby causing the height of the connecting plate 28 to change. The upper surface of the connecting plate 28 is fixed. A spring 27 is connected, with one end of the spring 27 connected to a fixed frame 30. The outer wall of the fixed frame 30 is rotatably connected to a fixed plate 5. At the same time, a spring 27 is also provided on the column 12 and connected to the fixed frame 30. The spring 27 works in conjunction with the vibrating motor 8 to achieve vibration dewatering of the screen 6. Since one end of the fixed plate 5 is fixedly connected, the other end can change height with the rise and fall of the connecting plate 28, thus realizing the adjustment of the installation angle of the screen 6. This adjustment structure can flexibly control the screen surface inclination angle according to the characteristics of the tailings, thereby adjusting the movement trajectory and residence time of the tailings on the screen surface, effectively preventing the material from accumulating or clogging on the screen surface, improving the dewatering efficiency, extending the service life of the screen 6, and enhancing the equipment's adaptability to different working conditions.
