Description
Technical Field
[0001] This utility model relates to the field of crack-resistant quartz sand screening technology, and in particular to a crack-resistant quartz sand screening machine with stable vibration screening function. Background Technology
[0002] Crack-resistant quartz sand screening machines are used to screen and classify crack-resistant quartz sand particles. Their working principle typically involves separating the particles according to physical properties such as size and density through vibration, rotation, or other mechanical action. These machines are widely used in industries such as construction, glass, ceramics, and metallurgy.
[0003] A crack-resistant quartz sand screening machine generally consists of the following key parts: Feeding and discharging device: This part is responsible for feeding the crack-resistant quartz sand raw material to be screened into the screening machine. The screened crack-resistant quartz sand particles are discharged through the discharge device, which may include multiple discharge ports to collect crack-resistant quartz sand of different particle sizes separately. Screening mechanism: This is the core part of the screening machine, usually composed of multiple layers of screens. The mesh size (i.e., aperture size) of the screens is determined according to the required screening particle size. The screening mechanism separates the crack-resistant quartz sand particles on the screens through vibration or rotation, achieving the purpose of grading. Vibrator or drive device: This part provides power to the screening mechanism, causing it to vibrate or rotate.
[0004] Conventional crack-resistant quartz sand screening machines classify crack-resistant quartz sand through vibration or rotation. When using rotation to classify crack-resistant quartz sand, circular rings are placed between the filter screens inside the device to prevent the crack-resistant quartz sand from accumulating and affecting the filtration efficiency of the filter screens. However, this method cannot stably agitate the crack-resistant quartz sand, and these rings may also block the discharge port, affecting the discharge efficiency. Therefore, a crack-resistant quartz sand screening machine with stable vibration screening function is proposed to solve the above problems. Utility Model Content

[0032] 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.
[0033] Reference Figure 1 , Figure 2 , Figure 4This utility model provides an embodiment of a crack-resistant quartz sand screening machine with stable vibration screening function, comprising a shell 1. The shell 1 provides a fixing effect for the internal connecting rod 6 and motor 7. The connecting rod 6 is rotatably connected to the inner wall of the shell 1. The connecting rod 6 drives the U-shaped groove 12 to rotate through the motor 7, causing the connected filter screen 3 to rotate. The outer wall of the connecting rod 6 is rotatably connected to a fixed outer shaft 5. Multiple sets of fixed outer shafts 5 are provided, each set at the lower end of the corresponding U-shaped groove 12. The lower end of the bottom set of fixed outer shafts 5 is fixed to the bottom of the shell 1. A support frame 10 is fixedly connected to the inner wall of the shell 1. The support frame 10 is fixedly connected to the outer wall of the fixed outer shaft 5, and the support frame 10 provides a fixing support effect for the fixed outer shaft 5. The outer wall of the outer shell 1 is fixedly connected to a discharge port 2. Multiple sets of discharge ports 2 are provided, each corresponding to different grades of crack-resistant quartz sand particles. The discharge ports 2 are located on the outer side of the outer shell 1. The rotation and vibration of the filter screen 3 causes the crack-resistant quartz sand on the upper side to be pushed outwards by inertia and the pushing of the actuating rod 4. A motor 7 is fixedly connected to the bottom of the inner wall of the outer shell 1, providing a fixed position for the motor 7. The output end of the motor 7 is fixedly connected to the lower end of the connecting rod 6, allowing the motor 7 to drive the connecting rod 6 to rotate. The inner wall of the outer shell 1 contacts the filter screen 3. A limiting groove is provided on the inner wall of the outer shell 1 at the contact point between the outer shell 1 and the filter screen 3 to prevent the crack-resistant quartz sand from flowing directly outwards from the outside of the filter screen 3. The sand falls directly to the next layer. Multiple sets of filter screens 3 are provided, with the mesh size decreasing from top to bottom, thus classifying the crack-resistant quartz sand. A lever 4 contacts the upper end of each filter screen 3. The lever 4 rotates in the opposite direction to the filter screen 3. This counter-rotation of the lever 4 and filter screen 3 allows for better and more active agitation of the crack-resistant quartz sand. Simultaneously, the arc-shaped lever 4 pushes the crack-resistant quartz sand outwards, allowing it to flow out through the outlet 2, improving filtration efficiency. A reversing mechanism is provided on the outside of the connecting rod 6. This reversing mechanism includes multiple sets of reversing outer shafts 8. Each set of reversing outer shafts 8 can drive the lever 4 to rotate in the opposite direction to the filter screen 3. The upper end of the reversing outer shaft 8 contacts the filter screen 3. The lower end of the fixed outer shaft 5 is rotatably connected, so that the fixed outer shaft 5 provides a fixing effect for the reverse outer shaft 8. The inner wall of the reverse outer shaft 8 is fixedly connected with a retaining tooth 15. The outer wall of the connecting rod 6 is fixedly connected with a main gear 14. The inner wall of the fixed outer shaft 5 is fixedly connected with a support rod 13. The outer wall of the support rod 13 is rotatably connected with a secondary gear 11, and the support rod 13 provides a fixing effect for the secondary gear 11. The outer wall of the main gear 14 meshes with the outer wall of the secondary gear 11. The outer wall of the secondary gear 11 meshes with the retaining tooth 15. The connecting rod 6 drives the main gear 14 to rotate. The main gear 14 drives the secondary gear 11 to rotate. The secondary gear 11 drives the retaining tooth 15 to rotate in the opposite direction relative to the connecting rod 6, so that the reverse outer shaft 8 rotates in the opposite direction to the U-shaped groove 12 at the lower end.
[0034] refer to Figure 3The outer wall of the reversing outer shaft 8 is provided with a sliding groove, and the inner wall of the actuating rod 4 is fixedly connected with a slider 9. The inner wall of the sliding groove is slidably connected to the outer wall of the slider 9. The sliding groove will lock the slider 9, causing the reversing outer shaft 8 to drive the actuating rod 4 to rotate. Because the actuating rod 4 is in close contact with the filter screen 3, the filter screen 3 will move up and down under the drive of the pulse vibrator 16. The slider 9 in the actuating rod 4 can move up and down in the sliding groove so that the actuating rod 4 can fit better with the filter screen 3.
[0035] refer to Figure 5 , Figure 6 A vibration mechanism is provided on the outer wall of the fixed outer shaft 5. The vibration mechanism includes a U-shaped groove 12, which provides a fixing effect for the filter screen 3. The lower end of the U-shaped groove 12 is rotatably connected to the upper end of the fixed outer shaft 5. Multiple sets of U-shaped grooves 12 are provided so that the fixed outer shaft 5 provides a fixing effect for the U-shaped grooves 12. The inner wall of the U-shaped groove 12 is fixedly connected to the outer wall of the connecting rod 6. The outer wall of the connecting rod 6 is provided with a protrusion that is directly fixedly connected to the U-shaped groove 12, so that the connecting rod 6 drives the U-shaped groove 12 to rotate. A pulse vibrator 16 is fixedly connected to the outer wall of the U-shaped groove 12. The pulse vibrator 16 is existing technology and drives the object to vibrate by emitting vibration pulses. The upper end of the pulse vibrator 16 is in contact with the filter screen 3. The pulse vibrator 16 drives the filter screen 3 to vibrate at high frequency by emitting vibration pulses through contact with the filter screen 3. The upper end of the U-shaped groove 12 is connected to the reverse outer shaft 8. The lower end is rotatably connected, and the connecting rod 6 drives the U-shaped groove 12 to rotate. The connecting rod 6 drives the reverse outer shaft 8 to rotate in the opposite direction through the secondary gear 11, so that the U-shaped groove 12 and the secondary gear 11 rotate in opposite directions. The inner wall of the U-shaped groove 12 is fixedly connected to the guide short shaft 17, which provides guidance for the spring 19 and can also protect the inner spring 19 from contacting the scattered crack-resistant quartz sand. The inner wall of the guide short shaft 17 is slidably connected to the pad 18. The upper end of the pad 18 is fixedly connected to the lower end of the filter screen 3. The pad 18 is elastically connected to the U-shaped groove 12 through the spring 19. One end of the spring 19 is fixedly connected to the lower end of the pad 18, and the other end of the spring 19 is fixedly connected to the inner wall of the U-shaped groove 12. The filter screen 3 can move up and down at high frequency on the inner wall of the U-shaped groove 12 through the spring 19 under the action of the pulse vibrator 16 to achieve the vibration effect.
[0036] Working principle: Before use, the crack-resistant quartz sand needs to be graded. Turning on motor 7 drives connecting rod 6 to rotate, and crack-resistant quartz sand is poured in from the top of outer casing 1. The rotation of connecting rod 6 causes U-shaped groove 12 to rotate, making the filter screen 3 connected to U-shaped groove 12 rotate. The main gear 14 fixed on connecting rod 6 drives secondary gear 11 to rotate, which in turn drives the retaining gear 15 to rotate in the opposite direction, thus causing the reverse outer shaft 8 to rotate in the opposite direction. The sliding groove on the reverse outer shaft 8 drives the slider 9 inside the actuating rod 4, causing the actuating rod 4 to... The filter screen 3 rotates in the opposite direction, allowing the actuating rod 4 to better agitate the crack-resistant quartz sand on the filter screen 3. The rotation of the filter screen 3, through centrifugal force, causes the crack-resistant quartz sand to move outward. Smaller pieces of crack-resistant quartz sand will fall into the lower layer through the filter screen 3, while the remaining crack-resistant quartz sand will reach the outer side of the filter screen 3 and flow out through the discharge port 2. The outer wall of the actuating rod 4 is arc-shaped, which can push the crack-resistant quartz sand outward while agitating it, thus speeding up the filtration and discharge process.
[0037] When filtering crack-resistant quartz sand, it is necessary to vibrate the filter screen 3 to enhance the filtration effect and prevent the crack-resistant quartz sand from accumulating on the filter screen 3 and affecting the filtration effect. The filter screen 3 can be driven to vibrate by the pulse vibrator 16. The pulse vibrator 16 will emit high-frequency vibration pulses to the filter screen 3. The filter screen 3 will move up and down at high frequency under the action of the spring 19 through the pad 18 connected at the bottom to achieve the vibration effect. When the filter screen 3 vibrates, the slider 9 on the inner wall of the actuating rod 4 will also slide up and down with the filter screen 3 on the inner wall of the sliding groove of the reverse outer shaft 8, so that the actuating rod 4 can better fit with the filter screen 3 and ensure the actuating rod 4 has the effect of turning over the crack-resistant quartz sand.
