Description
Technical Field
[0001] This utility model relates to the technical field of quartz sand screening devices, and in particular to a simple quartz sand screening device. Background Technology
[0002] In the processing and application of quartz sand, screening is a key step in improving the quality of quartz sand.
[0003] In the prior art, Chinese Patent No. CN220072396U discloses a quartz sand screening machine, including a main body, a bracket set at the bottom of the main body, and motors symmetrically installed at the bottom of the main body. The bottom of the motor is fixed with a base, and the bottom of the main body is fixed with an installation plate. A locking mechanism is provided at the connection between the base and the installation plate. The locking mechanism consists of a limiting block, a limiting groove, and a limiting component. The limiting groove is opened on the surface of the installation plate, and the limiting block is fixed to the bottom of the base.
[0004] However, the screening equipment in this patent suffers from the same drawbacks as existing screening equipment: the screening angle is mostly fixed, and the angle between the screen and the horizontal plane cannot be adjusted. For example, in actual production, the moisture content and particle size distribution of quartz sand often vary from batch to batch: dry, fine-grained quartz sand tends to accumulate on screens with a fixed angle, resulting in low screening efficiency; damp, agglomerated quartz sand, due to insufficient gravity, is difficult to move along the screen with a fixed angle, easily clogging the mesh; and for quartz sand with a mixture of coarse and fine particles, the fixed angle cannot accommodate the screening speed of different particles, often resulting in insufficient screening of fine particles and premature discharge of coarse particles. This inability to adjust the angle leads to poor adaptability of the screening device, making it difficult to match complex raw material characteristics. Utility Model Content
[0005] In view of the technical problem that the screening angle of existing screening equipment is mostly fixed and the angle between the screen and the horizontal plane cannot be adjusted, this utility model provides a simple quartz sand screening device.

[0007] A further feature of this invention is that a feed hopper is fixedly connected to the top of the fixed frame, a guide plate is fixedly connected to one end of the fixed frame, and a discharge hopper is fixedly connected to the bottom of the frame.
[0008] A further feature of this invention is that a hinge is provided between the adjustment frame and the machine frame, and the adjustment frame and the machine frame are rotatably connected by the hinge.
[0009] A further feature of this invention is that a mounting base is fixedly connected to the outside of the frame, the adjustment assembly includes a gear and an arc-shaped rack, a rotating rod is rotatably connected to the outside of the mounting base, the gear is fixedly connected to the rotating rod, the arc-shaped rack is fixedly connected to the adjustment frame, the arc-shaped rack meshes with the gear, and the arc-shaped rack and the hinge are concentric circles.
[0010] A further feature of this invention is that a fixed frame is fixedly connected to the outside of the frame, a housing is fixedly connected to the fixed frame, a worm and a worm wheel are rotatably connected inside the housing, and one end of the rotating rod extends into the housing and is fixedly connected to the worm wheel.
[0011] A further feature of this invention is that a rotating shaft is rotatably connected to the outside of the housing, the rotating shaft is fixedly connected to a worm gear, and a handwheel is fixedly connected to the outside of the rotating shaft.
[0012] A further feature of this invention is that one end of the rotating rod extends to the outside of the housing and is fixedly connected to a positioning plate. The positioning plate has multiple positioning ports on its outside, and the housing has positioning holes on its outside. A positioning strip is inserted between the positioning holes and the positioning ports.
[0013] A further feature of this invention is that a magnet block is fixedly connected to one end of the positioning strip and the inner wall of the positioning hole, and the magnet blocks are arranged with opposite poles attracting each other.
[0014] The beneficial effects of this invention are as follows: With the adjustable components, the screening angle can be flexibly adjusted according to the different particle sizes and moisture content of the quartz sand, improving screening efficiency and effectiveness. For example, for damp quartz sand that is prone to clumping, the tilt angle can be appropriately increased to utilize gravity to assist material movement; for finer quartz sand, the tilt angle can be decreased to extend the screening time and ensure thorough screening. The overall operation is simple and easy to understand, and the equipment is convenient to maintain, making it suitable for small to medium-scale quartz sand processing. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1-7 The present invention will be further described below.
[0019] To address the problems existing in the background technology, this application proposes the following technical solution: A simple quartz sand screening device, comprising a frame 1, an adjusting frame 3 rotatably connected to the frame 1, a fixed frame 5 above the adjusting frame 3, a screen 4 fixedly connected to the bottom of the fixed frame 5, multiple sets of springs 10 connected between the fixed frame 5 and the adjusting frame 3, a vibrating motor 9 fixedly connected to the outside of the fixed frame 5, and an adjusting component for adjusting the angle of the adjusting frame 3 on the frame 1; a feed hopper 6 fixedly connected to the top of the fixed frame 5, a guide plate 7 fixedly connected to one end of the fixed frame 5, and a discharge hopper 2 fixedly connected to the bottom of the frame 1; a hinge 8 is provided between the adjusting frame 3 and the frame 1, and the adjusting frame 3 and the frame 1 are rotatably connected by the hinge 8; the frame 1, as the basic support structure of the entire device, is welded from high-strength steel and can stably bear the weight of all components such as the adjusting frame 3 and the fixed frame 5, ensuring that there will be no shaking or displacement due to vibration during the screening process. The adjusting frame 3 is rotatably connected to the frame 1 via the hinge 8. This connection method allows the adjusting frame 3 to rotate flexibly around the hinge 8, thereby driving the fixed frame 5 to adjust the tilt angle to adapt to the screening requirements of quartz sand of different particle sizes.
[0020] The screen 4 at the bottom of the fixed frame 5 is the core component for achieving the screening function. Its mesh size can be selected according to actual needs, and it can separate quartz sand of different particle sizes. The multiple sets of springs 10 between the fixed frame 5 and the adjusting frame 3 play a role in buffering and amplifying the vibration when the vibrating motor 9 is working, so that the fixed frame 5 and the screen 4 generate high-frequency vibration, causing the quartz sand to jump quickly on the screen 4, accelerating the screening speed, and at the same time preventing the quartz sand from clogging the mesh.
[0021] The vibrating motor 9 provides power for screening. Fixed to the outside of the fixed frame 5, it directly drives the frame to vibrate, resulting in high vibration efficiency and low energy consumption. The feed hopper 6 at the top of the fixed frame 5 facilitates the addition of quartz sand. The large opening of the feed hopper 6 allows for feeding via conveyor belt or manual operation, preventing quartz sand spillage. The guide plate 7 at one end of the fixed frame 5 accurately guides the screened quartz sand to a designated location, preventing scattering. The discharge hopper 2 at the bottom of the frame 1 collects the fine quartz sand particles after screening for centralized processing. The overall structure is compact, with all components working collaboratively to efficiently complete the quartz sand screening operation. Its simple operation makes it suitable for small to medium-sized production scenarios.
[0022] In this embodiment, a mounting base 12 is fixedly connected to the outside of the frame 1. The adjustment assembly includes a gear 13 and an arc-shaped rack 11. A rotating rod 14 is rotatably connected to the outside of the mounting base 12. The gear 13 is fixedly connected to the rotating rod 14. The arc-shaped rack 11 is fixedly connected to the adjustment frame 3 and meshes with the gear 13. The arc-shaped rack 11 and the hinge 8 are concentric circles. A fixing frame 15 is fixedly connected to the outside of the frame 1. A housing 16 is fixedly connected to the fixing frame 15. A worm gear 19 and a worm wheel 18 are rotatably connected inside the housing 16. One end of the rotating rod 14 extends into the housing 16 and is fixedly connected to the worm wheel 18. A rotating shaft 17 is rotatably connected to the outside of the housing 16. The rotating shaft 17 is fixedly connected to the worm gear 19. A handwheel is fixedly connected to the outside of the rotating shaft 17. The mounting base 12 outside the frame 1 provides a stable rotational support for the rotating rod 14, ensuring that the rotating rod 14 is stable and reliable when driving the gear 13 to rotate. In the adjusting assembly, gear 13 meshes with the arc-shaped rack 11. When gear 13 rotates, it drives the arc-shaped rack 11 to move, thereby causing the adjusting frame 3 to rotate around the hinge 8, thus adjusting the angle of the fixed frame 5. The arc-shaped rack 11 and the hinge 8 are designed as concentric circles, ensuring that the arc-shaped rack 11 maintains good meshing with gear 13 during movement, avoiding jamming or tooth disengagement, and making the angle adjustment smooth and stable.
[0023] The housing 16 on the fixed frame 15 protects the internal worm gear 19 and worm wheel 18 from external dust and debris, extending their service life. The cooperation between the worm gear 19 and worm wheel 18 has the effect of speed reduction and force amplification. When the operator turns the handwheel, the rotating shaft 17 drives the worm gear 19 to rotate, which in turn drives the rotating rod 14 and gear 13 to rotate. Only a small force is needed to rotate the adjusting frame 3, reducing the difficulty of operation. The handwheel provides the operator with a convenient point of force application. Turning the handwheel allows for precise control of the rotation angle of the adjusting frame 3, making it easy to adjust the fixed frame 5 to the optimal screening angle and improve screening efficiency. This angle adjustment method has a simple structure and precise adjustment, and can flexibly adjust the angle of the fixed frame 5 according to the particle size and moisture content of the quartz sand, ensuring stable screening results.
[0024] In this embodiment, one end of the rotating rod 14 extends to the outside of the housing 16 and is fixedly connected to a positioning plate 20. The positioning plate 20 has multiple sets of positioning ports 21 on its exterior, and the housing 16 has positioning holes 22 on its exterior. A positioning strip 23 is inserted between the positioning holes 22 and the positioning ports 21. A magnet is fixedly connected to one end of the positioning strip 23 and the inner wall of the positioning hole 22, with opposite poles attracting each other. Multiple positioning ports 21 are provided on the positioning plate 20 extending from the rotating rod 14 to the outside of the housing 16, which cooperate with the positioning holes 22 on the outside of the housing 16. By inserting the positioning strip 23, the rotating rod 14 can be fixed, preventing the adjusting frame 3 from shifting angle due to vibration during screening and ensuring the stability of the fixed frame 5's angle. The insertion of the positioning strip 23 is simple; it only needs to be inserted into the positioning ports 21 and the positioning holes 22 to complete the fixation, requiring no complex tools and facilitating quick operation by the operator.
[0025] One end of the positioning strip 23 is attracted to the opposite poles of the magnet on the inner wall of the positioning hole 22, which enhances the fixing effect of the positioning strip 23 and prevents it from accidentally falling off during equipment vibration, ensuring that the rotating rod 14 is firmly locked. The attractive force of the magnet is moderate, which ensures the stable fixing of the positioning strip 23 without affecting its normal insertion and removal. The operator can easily pull out the positioning strip 23 for angle adjustment with a little force. This locking structure makes the fixing after angle adjustment more reliable, avoiding the impact of angle changes caused by equipment vibration on the screening effect. At the same time, it is easy to operate and improves the flexibility and stability of equipment use.
[0026] The usage method of this embodiment is as follows: Start the vibration motor 9 to drive the fixed frame 5 and the screen 4 to vibrate, and add the quartz sand into the fixed frame 5 through the feed hopper 6, and then screen it through the screen 4; In addition, if it is necessary to adjust the screening angle of the fixed frame 5, simply pull out the positioning strip 23, turn the handwheel to drive the rotating shaft 17 and the worm gear 19 to rotate, the worm gear 19 drives the worm wheel 18 to rotate, the worm wheel 18 drives the rotating rod 14 to rotate, the rotating rod 14 drives the gear 13 to rotate, and the gear 13 drives the arc rack 11 to rotate, thereby realizing the rotation adjustment of the adjusting frame 3. The adjusting frame 3 drives the fixed frame 5 to adjust the angle. After the adjustment is completed, insert the positioning strip 23 into the positioning port 21 and the positioning hole 22 to lock the rotating rod 14.
[0027] The vibrating motor 9 drives the fixed frame 5 and the screen 4 to generate high-frequency vibration. The spring 10 between the fixed frame 5 and the adjusting frame 3 further amplifies the amplitude during vibration, causing the screen 4 to vibrate continuously. Quartz sand is then poured into the fixed frame 5 through the feed hopper 6. The quartz sand falls onto the vibrating screen 4. Fine particles of quartz sand fall through the mesh of the screen 4 and are collected by the discharge hopper 2 at the bottom of the frame 1. Coarse particles of quartz sand move along the direction of the guide plate 7 on the screen 4 under the action of vibration and are discharged through the guide plate 7, completing the screening process. The entire screening process is highly automated. The continuous vibration of the vibrating motor 9 ensures efficient screening, and the buffering effect of the spring 10 reduces equipment noise and wear.
[0028] With adjustable settings, the screening angle can be flexibly adjusted according to the different particle sizes and moisture content of the quartz sand, improving screening efficiency and effectiveness. For example, for moist quartz sand that is prone to clumping, the tilt angle can be appropriately increased to utilize gravity to assist material movement; for finer quartz sand, the tilt angle can be decreased to extend the screening time and ensure thorough screening. The overall operation is simple and easy to understand, and the equipment is easy to maintain, making it suitable for small to medium-scale quartz sand processing.
