Description

Technical Field

[0001] This utility model relates to the field of quartz sand cleaning technology, specifically a vibrating dewatering screen for natural quartz sand. Background Technology

[0002] The quartz sand vibrating dewatering screen is a high-efficiency dewatering device specifically designed for mineral particles such as quartz sand. It uses the excitation force generated by high-frequency vibration to continuously loosen and convey the wet material layer on the screen surface. At the same time, the fine pore size of the screen mesh rapidly separates water from solid particles. During the vibration process, the material is evenly spread on the screen surface under the action of inertial force, which not only avoids local accumulation that affects dewatering efficiency, but also accelerates the discharge of free water through the screen through continuous vibration. Ultimately, it can significantly reduce the moisture content of quartz sand while maintaining stable particle size distribution. It is widely used in industrial scenarios that require efficient solid-liquid separation, such as quartz sand purification and tailings dry discharge.

[0003] Existing quartz sand vibrating dewatering screen devices often suffer from a lack of effective material distribution design, resulting in severe imbalance in the distribution of incoming material when it enters the screen surface. When the material rushes in in a pulsed or unbalanced manner, local areas of the screen surface will accumulate due to the instantaneous material thickness exceeding the limit. This not only hinders the path of water through the screen and reduces the dewatering efficiency, but also aggravates the wear of the screen.

[0004] Therefore, we propose a vibrating dewatering screen for natural quartz sand. Utility Model Content

[0005] The purpose of this invention is to provide a vibrating dewatering screen for natural quartz sand to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vibrating dewatering screen for natural quartz sand, comprising:

[0007] A vibration frame, wherein a fixed plate is fixedly connected to the inner wall of the vibration frame, springs are installed at equal intervals on the top of the fixed plate, a dehydration plate is fixedly connected to the other end of the spring, and a support plate is fixedly connected between the two fixed plates;

[0008] A vibration mechanism is installed on the top of the support plate. The vibration mechanism includes guide rails. The top of the support plate is symmetrically and fixedly connected to the guide rails. Top blocks are slidably installed inside the two guide rails. The top blocks have movable grooves inside, and movable blocks are slidably installed inside the movable grooves.

[0009] The material leveling mechanism is installed inside the vibrating frame. The material leveling mechanism includes a conveying cylinder. The conveying cylinder is symmetrically fixedly connected inside the vibrating frame. An inlet is opened on the outer side of the top of the conveying cylinder. A rotating rod is rotatably installed inside the conveying cylinder.

[0010] Preferably, the vibration mechanism further includes a fixed disk, which is fixedly connected inside the movable block. A bracket is fixedly connected to one side of the guide rail, and a connecting rod is fixedly connected to the front end of the fixed disk. A rotary motor is installed at the front end of the bracket, and the output end of the rotary motor is fixedly connected to the connecting rod. When the rotary motor starts, its output end drives the fixed disk to rotate through the connecting rod. The movable block on the fixed disk slides in the movable groove of the top block. Due to the eccentric setting of the fixed disk, the top block reciprocates within the symmetrical guide rails on the top of the support plate, thereby generating a high-frequency periodic excitation force on the dewatering plate.

[0011] Preferably, a conveyor belt is rotatably mounted on the inner wall of the vibration frame.

[0012] Preferably, the material leveling mechanism further includes helical blades. The helical blades are fixedly connected to the outer side of the rotating rod. A discharge port is opened on the outer side of the bottom end of the conveying cylinder. A drive motor is installed on the outer side of the vibrating frame, and the output end of the drive motor passes through the inside of the vibrating frame and is fixedly connected to the rotating rod. Quartz sand enters the conveying cylinder of the material leveling mechanism through the inlet. After the drive motor starts, its output end drives the rotating rod to rotate, and the helical blades on the outer side of the rotating rod rotate accordingly, uniformly conveying the quartz sand within the conveying cylinder, and then discharging it from the discharge port.

[0013] Preferably, a reciprocating lead screw is rotatably mounted inside the vibrating frame, and gears are symmetrically rotatably mounted on one side of the vibrating frame. Two gears are fixedly connected to the reciprocating lead screw and the rotating rod, respectively, and the two gears are meshed together. Meshing blocks are meshed on the outer sides of both ends of the reciprocating lead screw, and an extension rod is fixedly connected to the bottom of each meshing block. A push plate is fixedly connected to the bottom of the extension rod. While the rotating rod rotates, the reciprocating lead screw, which is meshed with it via gears, also rotates synchronously. The meshing blocks on the outer sides of both ends of the reciprocating lead screw reciprocate under the action of the lead screw, and the extension rod at the bottom of the meshing blocks drives the push plate to move back and forth, further evenly pushing the quartz sand falling from the discharge port onto the conveyor belt.

[0014] Preferably, a recycling bin is installed inside the front end of the vibration frame.

[0015] Preferably, a control panel is installed on the outside of the vibration frame, and both the rotating motor and the drive motor are electrically controlled and connected by the control panel.

[0016] Compared with existing technologies, the beneficial effects of this utility model are as follows: The cooperation of the guide rail, top block, movable groove, movable block, fixed disc, support, connecting rod, and rotating motor enables the material layer on the screen surface to remain in a loose, suspended state through high-frequency periodic excitation force. This effectively disrupts the capillary water absorption and surface tension between particles, accelerating the detachment of free water from the sand particle surface and allowing it to pass through the screen quickly. Furthermore, the inertial throwing action ensures uniform material distribution, preventing local accumulation that hinders drainage and significantly improving dewatering efficiency. The cooperation of the conveyor cylinder, feed inlet, rotating rod, spiral blades, discharge outlet, drive motor, reciprocating screw, meshing block, extension rod, and push plate ensures uniform material distribution on the screen surface, significantly improving the processing efficiency and operational stability of the dewatering screen. A uniform material layer ensures balanced load across all areas of the screen, preventing screen breakage and vibration system fatigue caused by localized overload, extending equipment lifespan. Balanced material distribution also reduces idle vibration energy consumption, lowers operating noise and dust emission, achieving efficient, low-consumption, and environmentally friendly continuous production.

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.

[0023] Please see Figure 1-4 A vibrating dewatering screen for natural quartz sand, comprising:

[0024] A vibration frame 1 has a fixed plate 2 fixedly connected to its inner wall. Springs 3 are installed at equal intervals on the top of the fixed plate 2. A dehydration plate 4 is fixedly connected to the other end of the springs 3. A support plate 5 is fixedly connected between the two fixed plates 2.

[0025] The vibration mechanism includes a guide rail 6. The guide rail 6 is symmetrically fixedly connected to the top of the support plate 5. A top block 7 is slidably installed inside the two guide rails 6. A movable groove 8 is opened inside the top block 7. A movable block 9 is slidably installed inside the movable groove 8.

[0026] The material leveling mechanism is installed inside the vibrating frame 1. The material leveling mechanism includes a conveying cylinder 15. The conveying cylinder 15 is symmetrically fixedly connected inside the vibrating frame 1. The outer side of the top of the conveying cylinder 15 is provided with a material inlet 16. A rotating rod 17 is rotatably installed inside the conveying cylinder 15.

[0027] Please see Figure 3 The vibration mechanism also includes a fixed disk 10, which is fixedly connected inside the movable block 9. A bracket 11 is fixedly connected to one side of the guide rail 6. A connecting rod 12 is fixedly connected to the front end of the fixed disk 10. A rotary motor 13 is installed at the front end of the bracket 11, and the output end of the rotary motor 13 is fixedly connected to the connecting rod 12. When the rotary motor 13 starts, its output end drives the fixed disk 10 to rotate through the connecting rod 12. The movable block 9 on the fixed disk 10 slides in the movable groove 8 of the top block 7. Due to the eccentric setting of the fixed disk 10, the top block 7 reciprocates within the symmetrical guide rail 6 on the top of the support plate 5, thereby generating a high-frequency periodic excitation force on the dewatering plate 4.

[0028] Please see Figure 4 The inner wall of the vibration frame 1 is rotatably mounted with a conveyor belt 14.

[0029] Please see Figure 4 The material leveling mechanism also includes a spiral blade 18. The spiral blade 18 is fixedly connected to the outer side of the rotating rod 17. A discharge port 19 is opened on the outer side of the bottom end of the conveying cylinder 15. A drive motor 20 is installed on the outer side of the vibrating frame 1, and the output end of the drive motor 20 passes through the inside of the vibrating frame 1 and is fixedly connected to the rotating rod 17. Quartz sand enters the conveying cylinder 15 of the material leveling mechanism through the feed port 16. After the drive motor 20 is started, its output end drives the rotating rod 17 to rotate, and the spiral blade 18 on the outer side of the rotating rod 17 rotates accordingly, uniformly conveying the quartz sand in the conveying cylinder 15, and then discharging it from the discharge port 19.

[0030] Please see Figure 4The vibrating frame 1 has a reciprocating screw 21 rotatably mounted inside. Gears 27 are symmetrically rotatably mounted on one side of the vibrating frame 1. Two gears 27 are fixedly connected to the reciprocating screw 21 and the rotating rod 17, respectively, and are meshed together. Meshing blocks 22 are meshed on the outer sides of both ends of the reciprocating screw 21. An extension rod 23 is fixedly connected to the bottom of the meshing blocks 22, and a push plate 24 is fixedly connected to the bottom of the extension rod 23. While the rotating rod 17 rotates, the reciprocating screw 21, meshing with it through the gears 27, also rotates synchronously. The meshing blocks 22 on the outer sides of both ends of the reciprocating screw 21 reciprocate under the action of the screw. The extension rod 23 at the bottom of the meshing blocks 22 drives the push plate 24 to move back and forth, further evenly pushing the quartz sand falling from the discharge port 19 onto the conveyor belt 14.

[0031] Please see Figure 1-4 The vibration frame 1 has a recycling bin 25 installed inside its front end.

[0032] Please see Figure 1-4 The vibration frame 1 is equipped with a control panel 26 on its outer side, and the rotating motor 13 and the drive motor 20 are both electrically controlled and connected by the control panel 26.

[0033] Working principle: First, the natural quartz sand to be processed enters the conveying cylinder 15 of the uniform material mechanism through the feed port 16. After the drive motor 20 starts, its output end drives the rotating rod 17 to rotate. The spiral blades 18 on the outside of the rotating rod 17 rotate accordingly, uniformly conveying the quartz sand in the conveying cylinder 15, and then discharging it from the discharge port 19. At the same time as the rotating rod 17 rotates, the reciprocating screw 21 connected to it through the gear 27 also rotates synchronously. The meshing blocks 22 on the outer sides of both ends of the reciprocating screw 21 reciprocate under the action of the screw. The extension rod 23 at the bottom of the meshing block 22 drives the push plate 24 to move back and forth, further uniformly pushing the quartz sand falling from the discharge port 19 onto the conveyor belt 14, ensuring that the material is evenly distributed on the screen surface and avoiding local accumulation. Then the conveyor belt 14 sends the uniformly distributed quartz sand to the dewatering plate 4 for dewatering.

[0034] Next, the vibration mechanism starts working. The rotating motor 13 starts, and its output end drives the fixed disk 10 to rotate through the connecting rod 12. The movable block 9 on the fixed disk 10 slides in the movable groove 8 of the top block 7. Due to the eccentric setting of the fixed disk 10, the top block 7 slides back and forth in the symmetrical guide rails 6 on the top of the support plate 5, thereby generating a high-frequency periodic excitation force on the dewatering plate 4. With the cooperation of the spring 3, the dewatering plate 4 generates high-frequency vibration, keeping the quartz sand material layer on the screen surface in a loose and suspended state. This high-frequency vibration effectively destroys the capillary water absorption and surface tension between particles, causing free water to accelerate away from the surface of the sand particles and quickly pass through the screen of the dewatering plate 4 and be discharged into the collection box 25 below for collection; it also causes the material to spread evenly on the dewatering plate 4 and move forward through inertial throwing action, avoiding local accumulation that hinders drainage.
