Description

Technical Field

[0001] This utility model relates to the field of tailings processing technology, specifically a fine sand dewatering screen for tailings processing. Background Technology

[0002] Tailings, often simply referred to as tailings, refers to the portion of minerals produced during the beneficiation process that has a low content of useful target components and cannot be directly used in production. It can replace or partially replace sand and gravel aggregates for use in infrastructure projects such as buildings, roads, and bridges.

[0003] Tailings processing generates a large amount of fine sand, which needs to be washed to remove the mud before it can be used. Traditional fine sand dewatering screens dewater by vibration, but the fine sand produced by vibration will settle. The settled fine sand is too dense and will clump together, which prevents water from draining quickly. Instead, the water will flow down the slope. Therefore, a fine sand dewatering screen for tailings processing is proposed to address the above problems. Utility Model Content

A pressure rod is fixedly connected to the surface of the slide rod, and the two ends of the pressure rod are slidably connected through the through hole. An extrusion block is fixedly connected to the surface of the screen frame, and the bottom surface of the extrusion block is semi-circular. A top block is fixedly connected to the surface of the screen frame, and the top block is a 1 / 4 cylinder.

[0011] Preferably, rollers are rotatably connected to the surfaces of both ends of the pressure rod where they contact the extrusion block.

[0012] Preferably, the support rod has a cavity, an elastic rope is fixedly connected to the cavity, a main magnetic block is fixedly connected to the other end of the elastic rope, and a secondary magnetic ring is fixedly connected to the end of the slide rod.

Detailed Implementation

[0026] 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.

[0027] Example 1

[0028] Please see Figure 1-6 As shown, a fine sand dewatering screen for tailings processing includes a base frame 1, a vibrating motor 8, and a screen frame 3. The screen frame 3 is movably mounted on the base frame 1 by a spring, and the vibrating motor 8 is fixed on the screen frame 3 to generate vibration.

[0029] The feature is that it also includes a drive motor 2, which is fixed on one side of the frame, and a rotating shaft 6 is rotatably connected to the frame, and the rotating shaft 6 is driven by the drive motor 2.

[0030] The rectangular frame 11 has a support rod 7 fixedly connected to the surface of the rotating shaft 6. The frame 11 is fixedly connected to the rotating shaft 6 through the support rod 7. The crossbar 15 is set on the frame 11 and is connected through a sliding mechanism.

[0031] There are two rotating shafts 6, which are respectively located on both sides of the vibration motor 8 and are driven by the drive motor 2. The sliding mechanism includes a slide rod 17, which is slidably connected to the support rod 7 by a spring. The support rod 7 has a through hole 13 on its surface. A pressure rod 12 is fixedly connected to the surface of the slide rod 17. The two ends of the pressure rod 12 are slidably connected through the through hole 13. An extrusion block 5 is fixedly connected to the surface of the screen frame 3. The bottom surface of the extrusion block 5 is semi-circular. A top block 9 is fixedly connected to the surface of the screen frame 3. The top block 9 is a 1 / 4 cylinder.

[0032] During operation, the vibration motor 8 is started, and then fine sand is poured into the screen frame 3 through the feeding device. Then, the drive motor 2 is turned on, which drives the rotating shaft 6 to rotate. The rotating shaft 6 drives the support rod 7, which in turn drives the square frame 11 to stir and disperse the fine sand in the screen frame 3. Dispersing the fine sand prevents incomplete filtration of moisture from the deposited fine sand, ensuring that soil remains within the sand and reducing the cleaning effect. Because there are two rotating shafts 6 connected by belt drive, both shafts 6 rotate synchronously when the drive motor 2 starts. When the support rod 7 moves to the position of the extrusion block 5, the arc-shaped extrusion block... 5 will squeeze the pressure rod 12, causing it to move downwards and drive the crossbar 15 into the fine sand. After the pressure rod 12 passes through the squeezing block 5, the spring will drive the crossbar 15 to retract. The up-and-down movement of the crossbar 15 can further improve the dispersing effect of the fine sand. When the rotating shaft 6 drives the pressure rod 12 to the position of the top block 9, the top block 9 will squeeze the pressure rod 12 downwards. Because the top block 9 is a 1 / 4 cylinder, after the pressure rod 12 passes through the top block 9, the spring will drive the crossbar 15 to return to its original position instantly. The vibration generated by the pressure rod 12 hitting the side wall of the through hole 13 will shake the fine sand off the surface of the frame 11 and the crossbar 15.

[0033] Several short rods are fixedly connected to the surface of the crossbar 15. There are two sets of crossbar 15, and the short rods on the surface of the two sets of crossbar 15 are staggered. Rollers 16 are rotatably connected to the two ends of the pressure rod 12 at the part of the surface that contacts the extrusion block 5. During operation, the two sets of crossbar 15 with staggered design can form a mesh-like design to further improve the dispersing effect. The rollers 16 can prevent the pressure rod 12 from directly colliding and squeezing with the extrusion block 5, reducing friction and thus reducing wear.

[0034] The support rod 7 has a cavity 19, and an elastic rope 18 is fixedly connected to the cavity 19. The other end of the elastic rope 18 is fixedly connected to a main magnetic block 21. The end of the slide rod 17 is fixedly connected to a secondary magnetic ring 23. The main magnetic block 21 and the secondary magnetic ring 23 are attracted to each other by opposite phases. An elastic membrane 22 is fixedly connected to the main magnetic block 21 and the secondary magnetic ring 23. The slide rod 17 has an air groove 25 and an air hole 26.

[0035] During operation, the slide rod 17 drives the auxiliary magnetic ring 23 to move. When it moves into the magnetic range of the main magnetic block 21, the two magnetic blocks will instantly attract each other through the principle of opposite phase attraction, which can improve the vibration effect and further improve the cleaning effect of the frame 11. At the same time, when the two magnetic blocks attract each other, they will squeeze the elastic membrane 22, so that the gas in the elastic membrane 22 is blown to the surface of the slide rod 17 through the air groove 25 and the air hole 26, preventing fine sand from entering the cavity 19 and affecting the normal sliding of the slide rod 17.
