Description

Technical Field

[0001] This utility model relates to the field of dewatering screen technology, specifically a dewatering screen for copper-molybdenum separation and tailings recovery. Background Technology

[0002] In tailings treatment, tailings water milling and flotation are required to separate copper and molybdenum. The copper and molybdenum rough concentrate is then separated into copper and molybdenum by hydrometallurgical process, so that the copper and molybdenum in the molybdenum tailings can be effectively utilized. After the copper and molybdenum ore particles are washed with water, they need to be rapidly dewatered and air-dried for subsequent processing. The existing dewatering method mainly uses a dewatering screen for vibration dewatering. In the vibration dewatering, a polarization servo motor performs high-speed and high-frequency motion, and the tailings particles on the screen body surface undergo high-frequency vibration motion to achieve the effect of dewatering copper and molybdenum ore particles.

[0003] In the current process of dewatering copper-molybdenum ore particles through a dewatering screen, the particles gradually fall off the screen. However, some particles adhere to the inner walls of the screen, causing more particles to accumulate. These particles remain in the screen, making it difficult to remove them. Furthermore, the screens are fixed with multiple bolts, requiring disassembly by rotating these bolts to replace them with different models, which is time-consuming and labor-intensive. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a dewatering screen for copper-molybdenum separation and tailings recovery. It solves the problem that some copper-molybdenum ore particles adhere to the inner walls of both sides of the dewatering screen, causing more copper-molybdenum ore particles to gradually adhere to the inner walls of both sides of the dewatering screen. This makes it inconvenient to clean and discharge the residual copper-molybdenum ore particles and requires replacing the screen with other models, which requires disassembling by turning multiple bolts, making the operation too time-consuming and labor-intensive.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dewatering screen for copper-molybdenum separation and tailings recovery, comprising a dewatering screen body located above a base, fixed frames fixedly connected to both sides of the top of the base, a fixed box fixedly connected between opposite sides of the two fixed frames, a servo motor fixedly connected to the bottom of the inner cavity of the fixed box, a reciprocating screw fixedly connected to the output shaft of the servo motor via a coupling, one end of the reciprocating screw being rotatably connected to the top of the inner cavity of the fixed box via a bearing, a ball nut provided on the surface of the reciprocating screw, sliding grooves provided on both sides of the fixed box, a sliding block slidably connected inside the sliding groove, a ball nut fixedly connected to one side of the sliding groove, a connecting plate fixedly connected to the other side of the sliding block, and a lower inclined shovel plate fixedly connected to the bottom of the connecting plate.

[0006] Preferably, the dewatering screen body includes a dewatering frame, a screen is provided at the bottom of the dewatering frame through an opening, an mounting plate is fixedly connected to the top of the dewatering frame, two sets of vibrating motors are fixedly installed on the top of the mounting plate, mounting blocks are fixedly connected to the front and rear of both sides of the dewatering frame, and a rubber spring is fixedly connected between the bottom of the mounting block and the top of the base.

[0007] Preferably, the bottom of the dewatering frame is fixedly connected with a plurality of support plates that cooperate with the screen, and both sides of the dewatering frame are fixedly connected with mounting rods, the surfaces of which are slidably connected with sliding plates.

[0008] Preferably, a circular plate is fixedly connected to one end of the mounting rod, and a metal spring is sleeved on the surface of the mounting rod between the sliding plate and the circular plate.

[0009] Preferably, a movable plate is fixedly connected to the bottom of the sliding plate, and a plurality of limiting rods are fixedly connected to one side of the movable plate.

[0010] Preferably, both sides of the dewatering frame and the screen are provided with a number of limiting holes that cooperate with the limiting rod.

[0011] Beneficial effects

[0012] This invention provides a dewatering screen for copper-molybdenum separation tailings recovery. Compared with existing technologies, it has the following advantages:

[0013] (1) This utility model controls the servo motor to drive the reciprocating screw to rotate. The reciprocating screw will drive the ball nut to move up and down reciprocally. The ball nut will drive the two connecting plates to move up and down reciprocally through the sliding block. The two connecting plates will drive the two lower inclined shovels to move up and down reciprocally. The two lower inclined shovels will shovel the inner walls on both sides of the dewatering frame, which can effectively remove the copper and molybdenum ore particles adhering to the inner walls on both sides of the dewatering frame, effectively preventing the copper and molybdenum ore particles from adhering to the inner walls on both sides of the dewatering frame, and ensuring that the copper and molybdenum ore particles are dewatered and discharged normally.

[0014] (2) By pulling two sliding plates to both sides, the sliding plates will move multiple limiting rods through the moving plate, so that the multiple limiting rods move out of the limiting hole, so that the limiting rods no longer jam the screen, thus making it easy to disassemble and replace the screen without having to turn multiple bolts to disassemble, making the operation more convenient.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a dewatering screen for copper-molybdenum separation and tailings recovery, including a dewatering screen body 2 located above a base 1. The dewatering screen adopts dual-electrode self-synchronization technology, a universal eccentric block, and an adjustable amplitude vibrator. Two independent vibrators are driven synchronously in opposite directions via a belt coupling. The centrifugal forces generated by the two sets of eccentric masses are superimposed along the vibration direction, and the reverse centrifugal forces cancel each other out, thus forming a single excitation vibration along the vibration direction, causing the dewatering frame 21 to perform a back-and-forth reciprocating tilting linear motion. Fixed frames 3 are fixedly connected to both sides of the top of the base 1, and a fixed box is fixedly connected between the opposite sides of the two fixed frames 3. 4. A servo motor 5 is fixedly connected to the bottom of the inner cavity of the fixed box 4. The servo motor 5 is electrically connected to an external power source and controlled by a control switch. The output shaft of the servo motor 5 is fixedly connected to a reciprocating screw 6 through a coupling. One end of the reciprocating screw 6 is rotatably connected to the top of the inner cavity of the fixed box 4 through a bearing. A ball nut 7 is provided on the surface of the reciprocating screw 6. Sliding grooves 8 are provided on both sides of the fixed box 4. A sliding block 9 is slidably connected inside the sliding groove 8. One side of the sliding groove 8 is fixedly connected to the ball nut 7. A connecting plate 10 is fixedly connected to the other side of the sliding block 9. A lower inclined shovel plate 11 is fixedly connected to the bottom of the connecting plate 10.

[0023] Furthermore, in order to effectively dewater copper-molybdenum ore particles, the dewatering screen body 2 includes a dewatering frame 21, with a lower inclined shovel plate 11 in contact with the inner wall of the dewatering frame 21. A screen 22 is provided at the bottom of the dewatering frame 21 through an opening. An installation plate 23 is fixedly connected to the top of the dewatering frame 21. Two sets of vibration motors 24 are fixedly installed on the top of the installation plate 23. The vibration motors 24 are electrically connected to an external power source and controlled by a control switch. Installation blocks 25 are fixedly connected to the front and rear of both sides of the dewatering frame 21. A rubber spring 26 is fixedly connected between the bottom of the installation block 25 and the top of the base 1.

[0024] It should be noted that water guide plates are fixedly connected to both sides of the bottom of the dehydration frame 21 to guide the dehydrated water to the middle position and collect it through the collection frame.

[0025] Furthermore, to facilitate the disassembly and replacement of the screen 22, several support plates 12 that cooperate with the screen 22 are fixedly connected to the bottom of the dewatering frame 21. Mounting rods 14 are fixedly connected to both sides of the dewatering frame 21. A sliding plate 13 is slidably connected to the surface of the mounting rod 14. A circular plate 15 is fixedly connected to one end of the mounting rod 14. A metal spring 16 is sleeved on the surface of the mounting rod 14 and between the sliding plate 13 and the circular plate 15. The metal spring 16 is made of stainless steel. A moving plate 17 is fixedly connected to the bottom of the sliding plate 13. Several limiting rods 18 are fixedly connected to one side of the moving plate 17. Several limiting holes 19 that cooperate with the limiting rods 18 are opened on both sides of the dewatering frame 21 and the screen 22.

[0026] In use, copper-molybdenum ore particles are added into the dewatering frame 21. By starting two vibration motors 24, the two vibration motors 24 drive the dewatering frame 21 to tilt and shake forward through the mounting plate 23. The dewatering frame 21 will drive the screen 22 to shake, which will cause the copper-molybdenum ore particles on the screen 22 to shake. During the shaking process, the copper-molybdenum tailings will move forward on the screen 22 and be gradually discharged. At the same time, the water in the copper-molybdenum ore particles will be shaken off, filtered, and discharged.

[0027] At the same time, the servo motor 5 drives the reciprocating screw 6 to rotate. The reciprocating screw 6 drives the ball nut 7 to move up and down reciprocally. The ball nut 7 drives the two connecting plates 10 to move up and down reciprocally through the sliding block 9. The two connecting plates 10 drive the two lower inclined shovel plates 11 to move up and down reciprocally. The two lower inclined shovel plates 11 shovel the inner walls on both sides of the dewatering frame 21, and shovel down the tailings adhering to the inner walls on both sides of the dewatering frame 21 for discharge.

[0028] When the screen 22 needs to be replaced, pull the two sliding plates 13 outward to squeeze the metal spring 16. The two sliding plates 13 will drive the two moving plates 17 to move to both sides. The moving plates 17 will drive multiple limiting rods 18 to move out of the limiting holes 19, so that the limiting rods 18 are no longer limiting and jamming the screen 22. Then pull the screen 22 upward to remove it from the front of the dewatering frame 21. Place the new screen 22 on the two support plates 12. Stop pulling the sliding plates 13. The metal spring 16 will be pushed to move back to the center by the force of the metal spring 16. The sliding plates 13 will drive the multiple limiting rods 18 to move through the moving plates 17, so that the multiple limiting rods 18 are inserted into the limiting holes 19 on the screen 22 for limiting and fixing.
