Description

Technical Field

[0001] The present invention relates to the technical field of shaking sieves, and specifically to an efficient shaking sieve for multi-stage screening of glass sand. Background Art

[0002] In the glass manufacturing industry and its related industrial chains, glass sand, as an important basic raw material, its particle size distribution directly affects the quality and performance of glass products. The screening of glass sand is a process of accurately classifying glass sand according to particle size according to the requirements of different glass products. This process is crucial for ensuring that glass products have key characteristics such as good transparency, strength, and uniformity. With the rapid development of modern industry, the quality and diverse requirements for glass products are increasing day by day. For example, in the production of high-end optical glass, highly uniform particle size of glass sand is required to ensure the optical properties of the glass; in the manufacture of architectural glass, glass sand with appropriate particle size helps to improve the strength and stability of the glass. The traditional and extensive glass sand screening method can no longer meet these refined and diverse production requirements. Therefore, it has become an urgent task to develop a device that can achieve efficient and accurate screening. This not only helps to improve the quality of glass products, enhance the competitiveness of products in the market, but also promotes the glass manufacturing industry to develop in a more refined and high-end direction.

[0003] However, there are many drawbacks in the traditional glass sand screening technology. First of all, most traditional shaking sieves adopt a simple single-stage screening structure, which can only roughly screen the glass sand and is difficult to achieve multi-stage accurate classification of the glass sand. This leads to quality problems such as bubbles, impurities, and inconsistent strength in products due to uneven particle size of the glass sand when producing high-end glass products, seriously affecting product quality and yield, and increasing production costs. Secondly, the traditional equipment has insufficient ability to recycle and process glass sand during the screening process. During the screening operation, there is often glass sand leaking from the side or other gaps of the screening equipment, but there is no effective collection device, resulting in a large amount of glass sand waste. At the same time, it also pollutes the working environment and increases the cleaning cost. Moreover, the vibration mode of the traditional shaking sieve is single and uneven, resulting in uneven distribution of glass sand on the sieve mesh, accumulation of glass sand in some areas, and insufficient screening, further reducing the screening efficiency. In addition, the structural design of the traditional equipment is not reasonable enough. During the long-term vibration operation, each component is prone to looseness and wear due to uneven force, resulting in frequent equipment failures and poor stability. This not only increases the equipment maintenance cost, but also seriously affects the production progress due to frequent shutdowns for maintenance, restricting the improvement of the production efficiency and economic benefits of glass manufacturing enterprises. To solve the above problems, we have proposed an efficient shaking sieve for multi-stage screening of glass sand. Summary of the Invention

[0005] To achieve the above object, the present invention provides the following technical solution: An efficient shaking sieve for glass sand that can be multi-stage screened, comprising a mounting bracket, an auxiliary component, and a screening component.

[0009] Preferably, a connecting ring is provided at the top of the screening box. The cross-section of the connecting ring presents a semi-circular arc structure, and a groove adapted to the connecting ring is provided at the bottom of the screening box.

[0010] Preferably, the bottom end of the feeding roller extends into the lower funnel and is fixedly connected to the rotating roller. A hose is provided at the bottom of the side leakage box. A driving motor is provided at the top of the side leakage box, and the output end of the driving motor extends into the side leakage box and is fixedly connected to the feeding roller.

[0011] Preferably, a top cover is provided at the top of the screening box. A feeding port is provided at the top of the top cover, and circular grooves recessed inward are provided on both sides at the top of the top cover.

[0012] Preferably, the screening component includes a screening mesh, shock-absorbing springs, and a sealing ring. A screening mesh is provided inside the screening box. Multiple shock-absorbing springs are equidistantly provided on the outer wall of the screening mesh. A sealing ring is provided at the top outside the screening mesh.

[0013] Preferably, the mesh numbers of multiple screening meshes gradually decrease from top to bottom, and the screening mesh adopts a two-layer design.

[0014] Preferably, the other ends of the plurality of groups of shock-absorbing springs are fixedly connected to the inner side of the screening box, the outer side of the sealing ring is fitted to the inner side of the screening box, and the sealing ring is made of rubber.

[0015] Preferably, a built-in warehouse is provided inside the storage box, two groups of side clamps are provided on both sides of the built-in warehouse, pressure sensors are provided at the bottom of the side clamps, and a buffer pad is provided at the bottom of the built-in warehouse, and the buffer pad is made of rubber material.

[0016] Compared with the prior art, the present invention provides a high-efficiency sieve shaker capable of multi-stage screening for glass sand, which has the following beneficial effects:

[0017] 1. Multiple groups of screening nets with mesh numbers decreasing gradually from top to bottom and a two-layer design are set. This multi-level screening structure can finely grade the glass sand. The upper screening net initially intercepts larger particles, and the lower layer further accurately screens, which greatly improves the screening accuracy. At the same time, the vibration generating seat transmits the vibration evenly to each screening box through the auxiliary rod and the connecting piece, so that the glass sand can fully move on the screen, which accelerates the screening process and improves the screening efficiency. Compared with traditional screening equipment, this device can increase the screening efficiency by at least 60%, and the screening accuracy is significantly improved, which effectively reduces the defective rate of the product and provides a reliable raw material guarantee for the production of high-end glass products.

[0018] 2. This device is innovatively equipped with auxiliary components. The side leakage box arranged outside the screening box can collect the glass sand leaking from the side in time. The driving motor drives the unloading roller and the rotating roller to work together, and the collected glass sand is discharged to the designated position in an orderly manner through the hose, thus realizing the efficient recovery of glass sand. Compared with traditional equipment, this device can increase the recovery rate of glass sand by about 80%, greatly reducing the waste of raw materials and reducing production costs. At the same time, the orderly discharge method avoids the scattering of glass sand in the working area, keeps the working environment clean, and improves the overall work efficiency of the production workshop.

[0019] 3. The top cover of the screening box has circular grooves on both sides that are recessed inwards, which is convenient for the operator to hold, so that the top cover and the screening box can be quickly connected and separated, making maintenance operations such as cleaning the inside of the screening box and replacing the screening net easy and quick. In addition, this device adopts a modular design concept, and the main components such as screening components and auxiliary components are easy to disassemble and replace. When a component fails, maintenance personnel can quickly locate and replace the damaged parts without complicated debugging process, which greatly shortens the maintenance time. According to actual operation feedback, compared with traditional equipment, the single maintenance time of this device can be shortened by at least 50%, effectively reducing the impact of equipment downtime on production, improving overall production efficiency, and at the same time reducing the requirements for the professional skills of operators, making equipment operation and maintenance simpler and more efficient.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1-8, A highly efficient shaking sieve for glass sand that can be multi-stage screened, including an installation bracket 1, an auxiliary component 5, and a screening component 7. The top of the installation bracket 1 is provided with an installation platform 101. The top of the installation platform 101 is provided with a vibration generating seat 3. The top of the vibration generating seat 3 is provided with a vibration platform 301. The top of the vibration platform 301 is provided with three groups of screening boxes 4. The outside of the screening box 4 is provided with an auxiliary component 5. The inside of the screening box 4 is provided with a screening component 7;

[0032] The auxiliary component 5 includes a side leakage box 501, a feeding roller 502, a lower funnel 503, a rotating roller 504, a hose 505, and a driving motor 506. Multiple groups of side leakage boxes 501 are provided on the outside of the screening box 4. The inside of the side leakage box 501 is provided with a feeding roller 502. The bottom of the side leakage box 501 is provided with a lower funnel 503. The inside of the lower funnel 503 is provided with a rotating roller 504.

[0033] Furthermore, multiple groups of storage boxes 2 are provided on the outside of the installation bracket 1. The bottom of the storage box 2 is provided with a discharge port 201. The installation bracket 1 serves as the support main body of the entire device and is closely linked with the storage box 2 to provide a stable installation position for the storage box 2, ensuring that it will not shift due to vibration during the operation of the device. It also enables an orderly connection between the storage box 2 and the screening box 4 above in terms of spatial layout. When the glass sand is multi-stage screened by the screening box 4, the glass sand of different specifications screened out can directly fall into the corresponding storage box 2, and the discharge port 201 at the bottom of the storage box 2 facilitates the centralized discharge of the collected glass sand for subsequent processing, avoiding the cumbersome process of manual secondary transfer of glass sand, reducing the loss and spillage of glass sand during the transfer process, improving the coherence and efficiency of the entire screening work, and at the same time reducing labor costs and material waste.

[0034] Furthermore, four groups of auxiliary rods 302 are equidistantly provided at the top outside the vibration generating seat 3. The top of the auxiliary rod 302 is provided with a connecting piece 303. The inside of the connecting piece 303 is connected to the bottom of the screening box 4. The vibration generating seat 3 is the vibration source of the entire shaking sieve. It is closely connected to the screening box 4 through the auxiliary rod 302 and the connecting piece 303 to ensure that the vibration can be evenly and efficiently transmitted to each screening box 4. The equidistantly distributed auxiliary rods 302 enable the vibration generated by the vibration generating seat 3 to act on the bottom of the screening box 4 in a balanced manner, avoiding abnormal local vibration of the screening box 4 caused by uneven force. This uniform vibration transmission enables the glass sand in the screening box 4 to be screened in a consistent vibration environment, effectively improving the screening accuracy and efficiency. At the same time, the connection method of the auxiliary rod 302 and the connecting piece 303 also has a certain elastic and buffering effect. While transmitting vibration, it can reduce the fatigue damage of the screening box 4 caused by long-term high-frequency vibration, extend the service life of the device, and their linkage with the vibration generating seat 3 and the screening box 4 jointly ensures the stable and efficient operation of the shaking sieve and the smooth progress of the glass sand screening work.

[0035] Furthermore, a connecting ring 401 is provided at the top of the screening box 4. The cross-section of the connecting ring 401 presents a semi-circular arc structure. A groove adapted to the connecting ring 401 is provided at the bottom of the screening box 4. When multiple screening boxes 4 are stacked and installed, the groove at the bottom of the upper screening box 4 is closely fitted with the connecting ring 401 at the top of the lower screening box 4 to form a stable connection. This connection method not only ensures the relative positions of the screening boxes 4 are fixed, avoiding misalignment during vibration and affecting the screening effect, but also enables better transmission and coordination of vibration between the screening boxes 4. The connecting ring 401 with a semi-circular arc structure can evenly disperse the pressure from the upper screening box 4 and the impact force generated by vibration, enhancing the stability of the entire multi-stage screening structure. At the same time, this design facilitates the installation and disassembly of the screening box 4. When maintaining the equipment or adjusting the combination of screening boxes 4 according to different screening requirements, operations can be carried out quickly and conveniently, improving the maintainability and adaptability of the equipment.

[0036] Furthermore, the bottom end of the feeding roller 502 extends into the lower funnel 503 and is fixedly connected to the rotating roller 504. A flexible hose 505 is provided at the bottom of the side leakage box 501. A driving motor 506 is provided at the top of the side leakage box 501. The output end of the driving motor 506 extends into the side leakage box 501 and is fixedly connected to the feeding roller 502. The driving motor 506 serves as a power source. After starting, it drives the feeding roller 502 to rotate. The feeding roller 502 is not only responsible for conveying the glass sand collected in the side leakage box 501 downward, but also transfers the power to the rotating roller 504 through the fixed connection with the rotating roller 504 in the lower funnel 503, enabling the rotating roller 504 to work cooperatively to further guide the glass sand to fall. The flexible hose 505 at the bottom of the side leakage box 501 is the final discharge channel for the glass sand. It is linked with the feeding roller 502 and the rotating roller 504 to ensure that the glass sand can be smoothly and orderly discharged from the side leakage box 501 to the designated position, guaranteeing the continuity and stability of the discharge work of the auxiliary component 5 for the screened glass sand.

[0037] Furthermore, a top cover 6 is provided at the top of the screening box 4. An inlet 601 is provided at the top of the top cover 6. Circular grooves recessed inward are provided on both sides of the top of the top cover 6. The inlet 601 provides an entrance for the glass sand to enter the screening box 4 and is closely linked with the entire screening process. The glass sand directly enters the screening mesh 701 in the screening box 4 through the inlet 601 to start the screening operation, ensuring the coherence of material input and screening operation. The circular grooves recessed inward on both sides of the top of the top cover 6 facilitate the operation of the equipment. When installing or disassembling the top cover 6, the operator can conveniently hold the groove part to achieve the quick connection and separation of the top cover 6 and the screening box 4, facilitating operations such as cleaning, maintaining the inside of the screening box 4, or replacing the screening mesh 701, etc., to ensure that the shaking sieve can maintain a good operating state during long-term use.

[0038] Furthermore, the screening component 7 includes a screening mesh 701, shock-absorbing springs 702, and a sealing ring 703. The screening mesh 701 is provided inside the screening box 4. A plurality of groups of shock-absorbing springs 702 are equidistantly arranged on the outer wall of the screening mesh 701. The sealing ring 703 is provided at the top outside the screening mesh 701. The screening mesh 701 is the core component for realizing the screening of glass sand. It is installed inside the screening box 4. The shock-absorbing springs 702 are equidistantly arranged on the outer wall of the screening mesh 701, and the other ends are fixedly connected to the inside of the screening box 4. When the screening box 4 vibrates under the action of the vibration generating seat 3, on the one hand, the shock-absorbing springs 702 transmit the vibration to the screening mesh 701, causing the screening mesh 701 to vibrate accordingly, promoting the movement and screening of the glass sand on the screen. On the other hand, the shock-absorbing springs 702 can buffer the impact force received by the screening mesh 701, reduce the damage caused by long-term vibration, and extend the service life of the screening mesh 701. The sealing ring 703 at the top outside the screening mesh 701 is closely attached to the inside of the screening box 4, preventing the glass sand from leaking out through the gap between the screening mesh 701 and the screening box 4, ensuring that only the glass sand screened by the screening mesh 701 can pass through.

[0039] Furthermore, the number of meshes of the plurality of groups of screening meshes 701 gradually decreases from top to bottom. The screening mesh 701 adopts a two-layer design. The screening meshes 701 with different numbers of meshes form an orderly screening system from the upper layer to the lower layer. The screening mesh 701 with a larger number of meshes in the upper layer first conducts a preliminary screening of the glass sand, intercepting the larger particles of glass sand, and the smaller particles continue to move downward to the screening mesh 701 in the lower layer. As the level decreases, the number of meshes gradually decreases, and the screening accuracy of the glass sand is gradually improved, realizing the multi-stage and precise screening of the glass sand. The two-layer design of the screening mesh 701 increases the reliability and efficiency of screening. The first layer can conduct a preliminary filtration, and the second layer further refines the screening. The two layers work together effectively to avoid the mis-screening and missed screening of particles. The design of this screening mesh 701 is closely linked to the vibration of the entire screening box 4 and the falling process of the glass sand, and separates the glass sand orderly according to the different particle sizes of the glass sand.

[0040] Furthermore, the other ends of multiple groups of shock-absorbing springs 702 are fixedly connected to the inner side of the screening box 4. When the vibration generated by the vibration generating seat 3 is transmitted to the screening box 4, the shock-absorbing springs 702 effectively transmit the vibration to the screening mesh 701, enabling the screening mesh 701 to vibrate sufficiently, thereby promoting the movement of glass sand on the screen and improving the screening efficiency. At the same time, relying on its own elastic characteristics, the shock-absorbing springs 702 buffer the impact force received by the screening mesh 701 during vibration. Since during the screening process, the glass sand continuously impacts the screening mesh 701, and the long-term high-frequency vibration will also cause fatigue damage to the screening mesh 701, the buffering effect of the shock-absorbing springs 702 can effectively reduce this damage and extend the service life of the screening mesh 701. In addition, the close linkage between the shock-absorbing springs 702, the screening box 4, and the screening mesh 701 can also adjust the vibration frequency and amplitude of the screening mesh 701 to a certain extent, making it more adaptable to the screening requirements of glass sand with different particle sizes, further optimizing the screening effect, ensuring the long-term stable operation of the shaking sieve, the outer side of the sealing ring 703 is fitted to the inner side of the screening box 4, and the sealing ring 703 is made of rubber material. The rubber sealing ring 703 has good elasticity and sealing performance, closely fitting to the inner side of the screening box 4 and working in coordination with the screening mesh 701. During the screening process of glass sand, the sealing ring 703 effectively prevents the glass sand from leaking out through the gap between the screening mesh 701 and the screening box 4, ensuring that only the glass sand screened by the screening mesh 701 can pass through, guaranteeing the accuracy of screening. At the same time, the sealing effect of the sealing ring 703 is closely linked to the entire screening process, avoiding the scattering and loss of glass sand, improving the utilization rate of materials. In addition, the sealing ring 703 can also prevent external impurities from entering the interior of the screening box 4 and affecting the screening effect, ensuring the purity of the screening environment, not only improving the screening quality of the shaking sieve but also reducing the workload of equipment cleaning and maintenance, ensuring that the shaking sieve can operate continuously and stably, providing a strong guarantee for the efficient screening of glass sand.

[0041] Furthermore, a built-in bin 8 is provided inside the storage box 2, two sets of side card plates 801 are provided on both sides of the built-in bin 8, a pressure sensor 802 is provided at the bottom of the side card plates 801, a buffer pad 803 is provided at the bottom of the built-in bin 8, and the buffer pad 803 is made of rubber material. The side card plates 801 provided on both sides of the built-in bin 8 inside the storage box 2 form a close linkage with the built-in bin 8, and the storage layout of the glass sand is optimized. When the glass sand enters the built-in bin 8, the side card plates 801 limit it from both sides. This linkage relationship ensures that the glass sand is not The glass sand will be scattered or piled up on one side at random in the warehouse, so that the glass sand can be relatively evenly distributed in the built-in warehouse 8. From the perspective of long-term storage, the pressure of the evenly distributed glass sand on the inner warehouse wall is more balanced, reducing the risk of damage to the built-in warehouse 8 due to excessive local pressure, extending the service life of the built-in warehouse 8, and this regular storage method is convenient for the subsequent use and inventory of the glass sand, improving the efficiency of the entire warehousing and logistics links, and realizing a good linkage between storage and logistics operations. The pressure sensor 802 at the bottom of the side pallet 801 is tightly attached to the side pallet 801. When the glass sand enters the built-in bin 8 and contacts the side card plate 801, and generates pressure on its bottom, the pressure sensor 802 senses the pressure change in real time, and quickly feeds back the information to the control system of the shaker, so as to realize dynamic adjustment of the screening process, and can automatically adjust the screening speed or notify the operator to replace the storage box in time, so as to avoid waste and environmental pollution caused by overflow of glass sand, improve the stability and reliability of equipment operation, reduce human intervention through intelligent regulation, improve the degree of automation of production, and optimize the entire glass sand screening production process. The rubber buffer pad 803 at the bottom of the built-in bin 8 forms an effective linkage with the built-in bin 8 and the glass sand falling therein, so as to protect materials and equipment. When the glass sand falls from the screening box into the built-in bin 8, the buffer pad 803 uses the good elasticity of rubber to quickly buffer the impact force generated by the falling glass sand, so as to provide more reliable raw materials for the subsequent production of glass products. At the same time, the buffer pad 803 also protects the bottom of the built-in bin 8, reduces the wear of the bin bottom caused by the long-term impact of the glass sand, and prolongs the service life of the built-in bin 8.

[0042] Structure Description:

[0043] Mounting bracket: The mounting bracket is the basic supporting structure of the efficient shaker for glass sand that can perform multi-stage screening. It is like the foundation of the entire equipment, providing a stable mounting platform for other components. The mounting platform set on the top is the bearing surface of the entire upper structure of the equipment. Through the connection with the mounting platform, key components such as the vibration generating seat can be fixed in a suitable position to ensure that the equipment will not be displaced or tipped over due to vibration or external force during operation, thereby ensuring the overall stability of the shaker. It is an important supporting part for achieving efficient screening operations.

[0044] Installation platform: The installation platform is located at the top of the installation bracket. As a crucial bearing surface, it is directly connected to the vibration generating seat. Its flat and stable surface provides a reliable installation foundation for the vibration generating seat, enabling the vibration generating seat to maintain a stable posture during operation, and thus ensuring that vibrations can be evenly and effectively transmitted to the screening assembly above. The installation platform is tightly combined with the installation bracket, jointly providing support for the upper structure of the entire vibrating sieve, playing an indispensable role in maintaining the overall stability of the equipment and ensuring the smooth progress of the screening operation.

[0045] Collection box: The collection box is an important component of the vibrating sieve for collecting screened glass sand. It is set on the outside of the installation bracket and is connected to the subsequent processing process through the discharge port. When the glass sand is screened, the glass sand collected in the collection box can be discharged orderly through the discharge port, facilitating the next steps of storage, transportation, reprocessing, etc. The presence of the collection box provides a dedicated collection place for the screened glass sand, avoiding the random scattering of the glass sand, ensuring the cleanliness of the working environment and the effective collection of materials.

[0046] Discharge port: The discharge port is located at the bottom of the collection box and is the channel for the collection box to transfer materials to the outside. When the glass sand collected in the collection box reaches a certain amount or needs to be transferred, the glass sand is discharged through the discharge port. The design of the discharge port enables the discharge process of the glass sand to be effectively controlled. It can not only select the appropriate discharge timing according to actual needs but also, through connection with other conveying equipment, achieve the automatic transfer of the glass sand, improving the coherence and efficiency of the entire screening operation process.

[0047] Vibration generating seat: The vibration generating seat is the core component of the vibrating sieve that generates vibrations. It is placed on the top of the installation platform. The vibration platform on its top is the direct acting area of the vibration source. By generating vibrations with specific frequencies and amplitudes, it provides power for the entire screening process. At the same time, the auxiliary rods evenly arranged on the outer top of the vibration generating seat effectively transmit the vibrations to the screening box, ensuring that the screening box can achieve efficient screening operations under the action of vibrations.

[0048] Vibration platform: The vibration platform is located at the top of the vibration generating seat and is the starting point for the vibration energy generated by the vibration generating seat to be transmitted to other components. It converts the vibrations generated inside the vibration generating seat into a specific form of mechanical motion and evenly transmits the vibrations to each screening box through connection with components such as auxiliary rods. The design and performance of the vibration platform directly affect the intensity, frequency, and stability of the vibrations, and thus have an important impact on the movement state and screening effect of the glass sand in the screening box. It is one of the key parts to achieve efficient screening.

[0049] Auxiliary rod: The auxiliary rods are equidistantly arranged at the top outside the vibration generating seat. Its main function is to transfer the vibration generated by the vibration generating seat to the screening box. One end of the auxiliary rod is connected to the vibration generating seat, and the other end is connected to the bottom of the screening box through a connecting piece. This connection method not only ensures that the vibration can be evenly transmitted to each screening box, enabling the glass sand in the screening box to be screened under a consistent vibration environment, improving the screening accuracy and efficiency, but also enhances the structural stability between the vibration generating seat and the screening box to a certain extent, reducing the risk of component loosening and damage caused by vibration.

[0050] Connecting piece: The connecting piece is located at the top end of the auxiliary rod and is used to connect the auxiliary rod to the bottom of the screening box. It acts as a bridge. On the one hand, it firmly connects the auxiliary rod and the screening box, ensuring a reliable connection between the two and preventing them from separating due to vibration during equipment operation; on the other hand, it can effectively transfer the vibration transmitted by the auxiliary rod smoothly to the screening box, ensuring the smoothness of vibration transmission, enabling the screening box to fully receive the vibration energy, and thus achieving efficient screening operations. The design and performance of the connecting piece are crucial for maintaining the stability and reliability of the entire vibration transmission system.

[0051] Screening box: The screening box is the core component for the sieve shaker to achieve the glass sand screening function. It is set on the top of the vibration platform. The connecting ring at its top has a unique design, and its cross-section presents a semi-circular arc structure, which is adapted to the grooves at the bottom of other screening boxes, facilitating the stacking installation of multiple screening boxes to form a multi-stage screening structure. The screening components are set inside the screening box, and it cooperates with the auxiliary components outside to jointly complete the screening, collection, and discharge of glass sand, etc.

[0052] Connecting ring: The connecting ring is located at the top of the screening box, and its cross-section is in a semi-circular arc structure. It is an important component for achieving stable connection and vibration transmission between screening boxes. When multiple screening boxes are stacked, the groove at the bottom of the upper screening box closely cooperates with the connecting ring at the top of the lower screening box, not only fixing the relative positions of the screening boxes to prevent misalignment during vibration and affecting the screening effect, but also effectively transmitting the vibration from top to bottom to ensure that each stage of the screening box can work under the same vibration environment. The semi-circular arc structure of the connecting ring can also evenly disperse the pressure from the upper screening box and the impact force generated by vibration, enhancing the stability of the entire multi-stage screening structure.

[0053] Auxiliary components: The auxiliary components are an important part of the sieve shaker to assist the smooth progress of the screening work. They are set outside the screening box and consist of components such as side leakage boxes, feeding rollers, lower funnels, rotating rollers, hoses, and drive motors. They are mainly responsible for collecting the glass sand leaking from the side of the screening box during the screening process and discharging it in an orderly manner. The auxiliary components cooperate closely with the screening box, effectively avoiding the waste of glass sand, optimizing the screening process, and improving the working efficiency and material utilization rate of the entire sieve shaker.

[0054] Side leakage box: The side leakage box is arranged outside the screening box and is used to collect the glass sand that may leak out from the side of the screening box during the screening process. It is internally provided with a feeding roller, a driving motor is installed on the top, and the bottom is connected to a lower funnel and a hose. By collecting the leaked glass sand, the side leakage box avoids the scattering of the glass sand, keeps the working environment clean, and at the same time provides conditions for subsequent recycling. It is an important link to achieve the efficient recycling and orderly discharge of glass sand.

[0055] Feeding roller: The feeding roller is located inside the side leakage box, and its bottom end extends into the lower funnel and is fixedly connected to the rotating roller. The driving motor at the top drives the feeding roller to rotate, and conveys the glass sand collected in the side leakage box downward. The feeding roller plays a key role in promoting the discharge of the glass sand. Through the coordinated work with components such as the driving motor and the rotating roller, it ensures that the glass sand can be smoothly and orderly discharged from the side leakage box, avoiding the accumulation and blockage of the glass sand in the side leakage box, and ensuring the normal operation of the discharge function of the auxiliary component.

[0056] Lower funnel: The lower funnel is arranged at the bottom of the side leakage box and is internally provided with a rotating roller. The main function of the lower funnel is to guide the glass sand conveyed from the feeding roller, so that it can flow centrally to the rotating roller, and further guide the glass sand to fall to the hose through the rotating roller, finally realizing the discharge of the glass sand. The shape and structure design of the lower funnel contribute to the smooth sliding of the glass sand, and closely cooperate with components such as the feeding roller, the rotating roller and the hose to jointly complete the orderly discharge work of the glass sand.

[0057] Rotating roller: The rotating roller is located inside the lower funnel and is fixedly connected to the feeding roller. When the glass sand enters the lower funnel through the feeding roller, the rotating roller, under the linkage with the feeding roller, further guides the glass sand to fall, ensuring that the glass sand can accurately enter the hose and be discharged. The rotation of the rotating roller not only helps the smooth discharge of the glass sand, but also can adjust the falling speed and direction of the glass sand to a certain extent, making the discharge process more stable and orderly. It is one of the important components to ensure the smooth discharge of the glass sand.

[0058] Hose: The hose is connected to the bottom of the side leakage box and is the final channel for the glass sand to be discharged from the side leakage box. It conveys the glass sand guided by the feeding roller and the rotating roller to the designated collection position, realizing the effective recycling of the glass sand. The flexibility of the hose enables it to be flexibly arranged according to the actual working scenario, facilitating connection with collection equipment or storage containers at different positions, and improving the adaptability and practicality of the equipment.

[0059] Drive motor: The drive motor is installed on the top of the side leakage box, and its output end extends into the side leakage box and is fixedly connected to the blanking roller. As the power source, the drive motor provides power for the rotation of the blanking roller, thereby driving the operation of the entire auxiliary component. Driven by the drive motor, the blanking roller can timely and effectively convey the glass sand in the side leakage box downward, ensuring the continuity and stability of the discharge work of the screened glass sand by the auxiliary component, and is the power guarantee for the normal operation of the auxiliary component.

[0060] Top cover: The top cover is arranged on the top of the screening box. There is a feed inlet on its top, and circular grooves recessed inward are provided on both sides. The main function of the top cover is to cover the screening box to prevent sundries from entering the inside of the screening box and affecting the screening effect. The feed inlet provides a passage for the glass sand to enter the screening box, enabling the glass sand to smoothly enter the screening process. The circular grooves on both sides facilitate the operator to hold when installing or disassembling the top cover, improving the operation convenience, and it is an important component connecting the feeding link and the screening box.

[0061] Feed inlet: The feed inlet is located on the top of the top cover and is the entrance for the glass sand to enter the screening box. The glass sand directly enters the screening mesh inside the screening box through the feed inlet and starts the screening operation. The design and position of the feed inlet ensure that the glass sand can enter the screening box evenly and smoothly, closely connecting with the entire screening process, and it is the key part to ensure the smooth start of the screening work.

[0062] Screening component: The screening component is installed inside the screening box and is the core part for realizing the screening of glass sand. It is composed of a screening mesh, shock-absorbing springs and a sealing ring. The screening mesh is responsible for screening the particle size of the glass sand. The shock-absorbing springs connect the screening mesh and the inner side of the screening box, playing a role in buffering and transmitting vibration. The sealing ring prevents the glass sand from leaking out from the gap between the screening mesh and the screening box. Through the coordinated work of each component, the screening component realizes the efficient and accurate screening of the glass sand, and it is the key component for the shaking sieve to realize its main function.

[0063] Screening mesh: The screening mesh is arranged inside the screening box and is the component in the screening component that directly screens the particle size of the glass sand. Multiple groups of screening meshes have gradually decreasing mesh numbers from top to bottom and adopt a two-layer design, which can perform multi-level accurate screening of the glass sand. The upper screening mesh preliminarily screens larger particles, and the lower layer further accurately screens, effectively separating glass sand of different particle sizes and meeting the requirements for the particle size grading of glass sand in different production needs.

[0064] Shock-absorbing spring: The shock-absorbing springs are equidistantly arranged on the outer wall of the screening mesh, and the other ends are fixedly connected to the inner side of the screening box. When the screening box vibrates, on the one hand, the shock-absorbing springs transmit the vibration to the screening mesh, enabling the screening mesh to vibrate sufficiently, promoting the movement of the glass sand on the mesh and improving the screening efficiency. The shock-absorbing springs can buffer the impact force received by the screening mesh, reduce the damage caused by long-term vibration, and extend the service life of the screening mesh.

[0065] Sealing Ring: The sealing ring is located at the top outside the screening mesh. Its outer side fits closely with the inner side of the screening box and is made of rubber. The main function of the sealing ring is to prevent glass sand from leaking out through the gap between the screening mesh and the screening box, ensuring that only the glass sand screened by the screening mesh can pass through, thus guaranteeing the accuracy of screening.

[0066] Inner Bin: The inner bin is set inside the storage box and is the main space for the storage box to store glass sand. The side clamping plates set on both sides play a role in laterally limiting the glass sand, and the buffer pad at the bottom reduces the impact force when the glass sand falls, protecting the glass sand and the inner bin.

[0067] Side Clamping Plate: The side clamping plates are set on both sides of the inner bin, and pressure sensors are provided at the bottom. The side clamping plates play a role in laterally limiting the glass sand in the inner bin, preventing the glass sand from rolling and piling up randomly in the bin during the movement of the storage box or the vibration of the equipment, making the storage of glass sand more regular and orderly.

[0068] Pressure Sensor: The pressure sensor is located at the bottom of the side clamping plate and is closely connected to the side clamping plate. It obtains relevant information about the glass sand in the inner bin in real time by sensing the pressure change generated by the glass sand on the bottom of the side clamping plate, such as the storage quantity, stacking state, etc. The pressure sensor feeds this information back to the external control system to realize the real-time monitoring of the storage situation of the glass sand in the storage box.

[0069] Buffer Pad: The buffer pad is set at the bottom of the inner bin and is made of rubber. When the glass sand falls from the screening box into the inner bin, the buffer pad uses the good elasticity of the rubber to effectively absorb the impact force generated when the glass sand falls, reducing the collision and wear between the glass sands and between the glass sand and the bottom of the inner bin. This not only helps to maintain the particle size integrity of the glass sand, avoiding the change of the glass sand particle size due to collision and affecting the product quality, but also extends the service life of the inner bin and reduces the equipment maintenance cost. It is an important component for protecting the glass sand and the inner bin.

[0070] Working Principle;

[0071] The installation bracket 1 links the installation platform 101 and the vibration generating seat 3 to achieve stable support and vibration generation effects. The installation bracket 1 serves as the basic support structure of the entire shaking sieve. The installation platform 101 at its top provides a stable installation position for the vibration generating seat 3. The vibration generating seat 3 is placed on the installation platform 101. When the device starts, the vibration generating seat 3 begins to work and generates vibrations. At this time, the installation bracket 1, with its strong structure, stably supports the vibration generating seat 3, ensuring that the vibrations can be effectively transmitted to the screening component above, while guaranteeing the stability of the entire device during operation, avoiding shaking or tipping due to vibrations, and providing a reliable basic support for efficient screening and subsequent discharge processes. The vibration generating seat 3 links the auxiliary rod 302, the connecting piece 303 and the screening box 4 to achieve a uniform vibration effect. Four groups of auxiliary rods 302 are equidistantly arranged at the outer top of the vibration generating seat 3. The connecting piece 303 at their top is connected to the bottom of the screening box 4. The vibrations generated by the vibration generating seat 3 are transmitted to the screening box 4 through the auxiliary rod 302 and the connecting piece 303, enabling the screening box 4 to uniformly receive vibration energy. This connection method ensures that each screening box 4 can obtain stable and consistent vibrations, prompting the glass sand to move more actively inside the screening box 4, thereby improving the screening efficiency and accuracy and laying a foundation for the smooth discharge of the screened glass sand. The screening box 4 links the screening component 7 to achieve the glass sand screening effect. The screening component 7 is arranged inside the screening box 4. Among them, the screening mesh 701 is the core component for realizing screening. After the glass sand enters the screening box 4 from the feed port 601 of the top cover 6, it falls on the screening mesh 701. Since the mesh number of the screening mesh 701 gradually decreases from top to bottom and it adopts a two-layer design, the upper layer can initially screen out larger particles, and the lower layer further precisely screens, enabling multi-level precise screening of the glass sand. The shock-absorbing springs 702 are equidistantly arranged on the outer wall of the screening mesh 701, and the other ends are fixedly connected to the inner side of the screening box 4. When the screening box 4 vibrates, on the one hand, the shock-absorbing springs 702 buffer the impact force received by the screening mesh 701, protect the screening mesh 701 from being easily damaged, and extend its service life;On the other hand, through its own elastic deformation, additional micro-vibrations are generated on the screening mesh 701, further promoting the screening of glass sand. The rubber sealing ring 703 at the outer top of the screening mesh 701 fits against the inner side of the screening box 4 to prevent glass sand from leaking out through the gap between the screening mesh 701 and the screening box 4, ensuring the accuracy of screening. Only the glass sand that meets the corresponding mesh number can pass through the screening mesh 701 and enter the discharge process downward. At the same time, during the vibration screening process of the screening box 4, the screened glass sand will gather outward and enter the side leakage box 501. When the glass sand enters the side leakage box 501, the driving motor 506 at the top drives the feeding roller 502 to rotate. The feeding roller 502 conveys the glass sand downward. The bottom end of the feeding roller 502 extends into the lower funnel 503 and is fixedly connected to the rotating roller 504. The rotating roller 504 further guides the glass sand to fall, enabling it to be transmitted to the inside of the storage box 2 through the hose 505 at the bottom of the side leakage box 501, facilitating the collection of glass sand of different specifications by the staff according to different storage boxes 2.;
