[0041] In order to better understand the above technical solution, the exemplary embodiments of the present utility model will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present utility model can be understood more clearly and thoroughly, and the scope of the present utility model can be fully conveyed to those skilled in the art.

[0042] As Figures 1 to 3 shown, according to an embodiment of the present application, a split-type high-frequency vibration superimposed sieve is provided, including: a sieve body 100 and a discharge box 200 which are separately arranged; wherein, a height difference is formed between the sieve body 100 and the discharge box 200 in the height direction, and the discharge box 200 is used to receive the materials sieved by the sieve body 100.

[0043] The split-type high-frequency vibrating multi-layer sieve provided by the embodiments of the present application includes a sieve body 100 and a discharge box 200 that are separately arranged; the sieve body 100 is the core component for performing the screening work. Driven by a high-frequency vibration motor, it can quickly and accurately screen the input materials. Since the sieve body 100 and the discharge box 200 are independent of each other, the vibration mode of the sieve body 100 is more free and efficient, and is not affected by the structure and weight of the discharge box 200. The height difference formed by the sieve body 100 and the discharge box 200 in the height direction. The existence of this height difference enables the screened materials to naturally and smoothly fall into the discharge box 200 under the action of gravity during the vibration screening process of the sieve body 100. At the same time, an appropriate height difference also avoids the splashing and rebound of the materials during the falling process, ensuring the stability and accuracy of the screening process.

[0044] Exemplarily, when processing ore materials with uneven particle sizes, the sieve holes on the sieve body 100 screen the materials according to preset specifications. Smaller particles fall through the sieve holes, while larger particles move in a specific direction under the vibration of the sieve body 100. When the fine particles pass through the sieve holes, due to the existence of the height difference, they can fall into the discharge box 200 in a more concentrated and orderly manner.

[0045] Exemplarily, the internal space of the discharge box 200 is spacious and can accommodate a large amount of screened materials. Moreover, the opening position and size of the discharge box 200 match the discharge end of the sieve body 100 to ensure that the materials can enter unobstructed.

[0046] Exemplarily, in order to better adapt to various complex working environments and different material characteristics, the material selection of the sieve body 100 and the discharge box 200 is also very crucial. Materials with high strength, wear resistance and good corrosion resistance are usually selected to ensure the reliability and stability of the equipment during long-term use.

[0047] In the prior art, there are mainly two structural deficiencies in the currently common high-frequency vibrating multi-layer sieves.

[0048] Exemplarily, the sieve body of the high-frequency vibrating multi-layer sieve with traditional stainless steel sieve sheets usually adopts an integrated design, and the sieve body and the discharge box form an inseparable whole. This design results in a significant increase in the weight of the sieve body, and due to the heavy weight at the lower discharge end, during the working process, materials are prone to accumulate at the lower part of the sieve sheets. This not only affects the normal screening process but also has the problem of poor high-frequency vibration effect. Specifically, the vibration frequency is difficult to reach the ideal state, and the screening of materials is not fine and uniform enough, thereby reducing the efficiency and quality of the entire production process.

[0049] Another common structure is the traditional stacked screen with the upper and lower screen material collection boxes arranged centrally. In this structure, the lower screen material collection box is arranged in the middle of the upper screen material collection box. This causes the surface of the lower screen material collection box to be eroded by the upper screen material for a long time, posing extremely high requirements for its material and sealing performance. However, even with high-quality materials and complex sealing designs, it is difficult to avoid the shortening of the equipment life due to material leakage and wear. Moreover, this complex structural design not only increases the manufacturing difficulty and cost but also brings many inconveniences during subsequent maintenance and repair, further increasing the operation and maintenance cost of the equipment.

[0050] The split-type high-frequency vibration stacked screen proposed by the present utility model includes a screen body 100 and a discharge box 200 that are separately arranged. There is a height difference between the screen body 100 and the discharge box 200 in the height direction. During operation, the screen body 100 vibrates at a high frequency to screen the material. Since the screen body 100 and the discharge box 200 are separately arranged, the weight of the screen body is greatly reduced, avoiding the problem of overweight at the lower discharge end, thus effectively preventing the accumulation of materials at the lower part of the screen. At the same time, this split-type design enables the discharge box 200 to better receive the materials screened by the screen body 100, reducing the possibility of material splashing and leakage. Moreover, due to the independence between the screen body 100 and the discharge box 200, during the maintenance and repair of the equipment, operations can be carried out separately for the screen body 100 and the discharge box 200, reducing the maintenance difficulty and cost, and improving the maintainability and service life of the equipment.

[0051] Exemplarily, in actual ore screening operations, for ore raw materials with different particle sizes, the split-type high-frequency vibration stacked screen of the present utility model can quickly and accurately separate fine materials and coarse materials. During the whole process, the vibration of the screen body 100 is stable and efficient, and there will be no uneven vibration or low efficiency due to weight and structural problems. And the discharge box 200 can accurately receive and store the screened materials, providing convenience for subsequent processing and transportation.

[0052] In summary, through the unique split-type design, the split-type high-frequency vibration stacked screen of the present utility model effectively overcomes various problems existing in the prior art, improves the screening efficiency, reduces the equipment investment and operation and maintenance cost, and has significant practical value and market prospects.

[0053] As Figures 1 to 3 shown, in some examples, the above-mentioned screen body 100 is inclined. Along the height direction, the lowest end of the inclined screen body 100 is the output end, the highest end of the inclined screen body 100 is the input end, and the output end of the screen body 100 extends into the interior of the discharge box 200.

[0054] In this technical solution, the screen body 100 is tilted relative to the discharge box 200, and its highest end is used as the input end, and the material is evenly fed into the screen body 100 from this end. Due to the existence of the tilt angle, the material will naturally move to the lowest end, that is, the output end, under the action of its own gravity. During the screening process, when the material gradually moves from the input end to the output end, the high-frequency vibration makes the material continuously roll and jump on the screen body 100, thereby achieving effective screening. Smaller particles can pass through the sieve holes smoothly, while larger particles continue to move along the screen surface to the output end.

[0055] The structure that the output end of the sieve body 100 is deeply inside the discharge box 200 can ensure that the screened materials fall into the discharge box 200 accurately and accurately, thereby minimizing the loss and splashing of materials. On the other hand, the output end deeply inside the discharge box 200 can also prevent the mixing of external impurities to a certain extent, thereby ensuring the purity of the screened materials.

[0056] For example, when processing materials with high water content, the inclined screen body 100 helps the water to flow down quickly and not accumulate on the screen surface, thereby improving the screening efficiency and effect. Moreover, for some materials that are easy to stick, the synergistic effect of the inclined setting and high-frequency vibration can effectively prevent the material from clogging and piling up on the screen body 100.

[0057] For example, in addition, the inclination angle of the screen body 100 can be flexibly adjusted according to different material characteristics and screening requirements. For materials with larger particles and heavier specific gravity, the inclination angle can be appropriately increased to speed up the movement of the materials; for materials with smaller particles and lighter specific gravity, the inclination angle can be appropriately reduced to increase the residence time of the materials on the screen body 100 to ensure the screening accuracy.

[0058] In summary, the inclined setting of the screen body 100 and the structural feature that its output end is deeply inserted into the discharge box 200 effectively improve the screening efficiency, ensure the screening quality, and have good adaptability and operability.

[0059] like Figures 1 to 4 As shown, in some examples, the above-mentioned discharge box 200 includes: a screen box body 210; a neutral plate 220, which is arranged inside the above-mentioned screen box body 210 to divide the above-mentioned screen box body 210 into at least two receiving spaces 201; a discharge pipe 230 is arranged at the bottom of the above-mentioned receiving space 201 for connecting with external equipment.

[0060] In this technical solution, the discharge box 200 includes a sieve box body 210, a neutral plate 220, and a discharge pipe 230. Among them, at least two receiving spaces 201 are separated inside the sieve box body 210 by the neutral plate 220. First of all, this technical feature can classify and store materials according to different material specifications or characteristics obtained by screening. For example, finer materials can be stored in one receiving space 201, while coarser materials are stored in another receiving space 201, thus realizing the preliminary classification of materials. Secondly, when multiple different materials need to be processed simultaneously, multiple receiving spaces 201 can correspond to different materials respectively, avoiding confusion and cross-contamination between materials.

[0061] A discharge pipe 230 is provided at the bottom of each receiving space 201. Through the discharge pipe 230, the materials in the receiving space 201 can flow into external equipment. The size and shape of the discharge pipe 230 are not limited and can be set according to the actual production needs such as external equipment to ensure that the materials can flow out smoothly and can be seamlessly connected to the external equipment. Exemplarily, in a large ore processing production line, the ores of different particle sizes obtained by screening can be directly transported to subsequent different processing equipment, such as crushers, mills, etc., through the discharge pipes 230 of their respective corresponding receiving spaces 201, realizing the efficient connection of the production process.

[0062] Exemplarily, the discharge pipe 230 can also be equipped with control valves to flexibly adjust the outflow speed and flow rate of the materials according to actual production requirements. Moreover, in order to adapt to different installation and connection requirements, the connection method of the discharge pipe 230 is diverse and can be threaded connection, flange connection, etc.

[0063] Exemplarily, the sieve box body 210, as the main part of the discharge box 200, is made of strong and durable materials, has sufficient strength and stability, and can withstand the impact and pressure of a large amount of materials.

[0064] In summary, the collaborative design of the sieve box body 210, the neutral plate 220, and the discharge pipe 230 of the discharge box 200 not only improves the efficiency of material classification and transportation but also enhances the compatibility and scalability of the entire equipment with the external system, providing great convenience for production operations.

[0065] Exemplarily, a discharge chute 700 for receiving materials is also provided at the bottom of the discharge box 200 and / or the sieve body 100. Among them, a discharge chute partition 710 is provided in the discharge chute 700, so that at least two discharge spaces 701 are separated in the discharge chute 700. The materials flowing out of the discharge pipe 230 can be received through the discharge spaces. Exemplarily, the discharge chute 700 can be installed or removed according to the user's usage requirements. When the discharge chute 5 is removed, the discharge pipe 230 is directly connected to the user's main pipeline.

[0066] As Figures 1 to 4 shown, in some examples, the split-type high-frequency vibration multi-layer sieve further includes: a separating member 300 disposed at the bottom end of the sieve body 100, and the neutral plate 220 supports the separating member 300.

[0067] In this technical solution, the separating member 300 is made of a steel plate, has the shape of the side of a pitched roof, and is welded to the lower part of the inclined sieve body 1; the separating member 300 with the shape of the side of a pitched roof is firmly connected to the lower part of the inclined sieve body 100 by welding, ensuring that it always remains stable in the high-frequency vibration working environment. The fine execution of the welding process makes the connection between the separating member 300 and the sieve body 100 close and seamless, and it can withstand long-term vibration and material impact without loosening or separation. The technical feature that the neutral plate 220 supports the separating member 300 not only provides additional support and stability for the separating member 300, but also can effectively disperse the pressure from the sieve body 100 and the material.

[0068] Exemplarily, when the material moves downward along the inclined sieve body 100, the shape of the side of the pitched roof of the separating member 300 can guide the material to flow more smoothly, reducing the accumulation and blockage of the material at the bottom end of the sieve body 100. At the same time, when the sieve body 100 vibrates during operation, the separating member 300 can limit the connection between the sieve body 100 and the discharge box 200.

[0069] Exemplarily, the material of the separating member 300 can be selected from materials with good wear resistance and corrosion resistance, which can operate stably for a long time under harsh working conditions.

[0070] As Figures 1 to 4 shown, in some examples, the split-type high-frequency vibration multi-layer sieve further includes: a sealing assembly 400 disposed between the sieve body 100 and the discharge box 200 for blocking the splashing material in the discharge box 200.

[0071] In this technical solution, there is a gap between the sieve body 100 and the discharge box 200, and the sealing assembly 400 is disposed between the sieve body 100 and the discharge box 200, which can achieve the technical effect of blocking the splashing material in the discharge box 200. Exemplarily, the sealing assembly 400 can be selected from but not limited to high-performance sealing materials with excellent elasticity and wear resistance.

[0072] During the process of material screening by the high-frequency vibration of the sieve body 100, the material in the discharge box 200 may splash due to vibration and the mutual collision of the materials. The sealing assembly 400 acts as a barrier and effectively blocks these splashing materials.

[0073] Exemplarily, the sealing assembly 400 is characterized by being easy to install and maintain. After long-term use, if the sealing performance deteriorates, it can be conveniently replaced or repaired to ensure that the split high-frequency vibrating multi-layer sieve always maintains a good working state.

[0074] The presence of the sealing assembly 400 effectively solves the problem of material splashing in the discharge box 200, providing an important guarantee for the stable and efficient operation of the split high-frequency vibrating multi-layer sieve.

[0075] As Figures 1 to 4 shown, in some examples, the above-mentioned sealing assembly 400 includes: a side sealing strip 410 disposed between the inner wall of the sieve body 100 and the sieve box body 210.

[0076] In this technical solution, the sealing assembly 400 includes a side sealing strip disposed between the sieve body 100 and the sieve box body 21. During the process of material screening with the high-frequency vibration of the sieve body 100, the side sealing strip 410 can effectively prevent materials from splashing out through the gap between the sieve body 100 and the inner wall of the sieve box body 210.

[0077] The side sealing strip 410 adapts to the small displacements caused by vibration and always maintains good sealing performance; the sealing baffle can block most of the splashing materials and prevent them from escaping from the discharge box 200; in actual working scenarios, even when facing the rapid processing of a large amount of materials and strong vibration, the side sealing strip 410 can excellently complete the task of blocking material splashing. This not only reduces material loss, improves production efficiency, but also avoids the pollution of the surrounding environment by splashing materials and potential hazards to operators.

[0078] As Figures 1 to 4 shown, in some examples, the above-mentioned sealing assembly 400 further includes: a top sealing strip 420 disposed between the neutral plate 220 and the partition member 300.

[0079] In this technical solution, the top sealing strip 420 is disposed between the neutral plate 220 and the partition member 300. During the operation of the split high-frequency vibrating multi-layer sieve, due to high-frequency vibration and the impact of material flow, gaps are likely to appear at the connection between the neutral plate 220 and the partition member 300, resulting in material leakage, and the presence of the top sealing strip 420 effectively solves this problem.

[0080] Exemplarily, the top sealing strip 420 can adopt a multi-layer sealing structure, and each layer has specific sealing functions. For example, the outer sealing layer can withstand large impact forces to prevent materials from directly breaking through the sealing strip; the middle sealing layer has good elasticity and can adapt to the relative displacement caused by vibration between the neutral plate 220 and the partition member 300; the inner sealing layer can further improve the sealing tightness to ensure that no tiny material particles pass through.

[0081] As Figure 1 shown, in some examples, the split-type high-frequency vibrating multi-layer sieve further includes: a feed box 500, which is arranged at the input end of the sieve body 100.

[0082] In this technical solution, the feed box 500 is arranged at the input end of the sieve body 100. Exemplarily, the feed box 500 can be made of a sturdy and durable material, so as to have good wear resistance and impact resistance.

[0083] During the operation of the equipment, the material to be sieved is first conveyed into the feed box 500. Exemplarily, a diversion plate and a buffer device can be arranged inside the feed box 500. The diversion plate can guide the material to enter the sieve body 100 in a predetermined direction and speed, avoiding the accumulation and deviation of the material; the buffer device can reduce the impact force when the material enters, and reduce the wear on the sieve body 100.

[0084] Exemplarily, the capacity of the feed box 500 is reasonably designed according to the actual production requirements. A larger capacity can meet the needs of large-scale continuous production, reduce the feeding frequency, and improve production efficiency; a smaller capacity is suitable for small-scale or intermittent production, saving space and cost.

[0085] In actual screening operations, the feed box 500 can effectively control the input speed and flow rate of the material, ensuring that the sieve body 100 can fully exert its screening performance. At the same time, the feed box 500 also has good sealing performance, preventing the material from leaking during the input process and avoiding polluting the working environment.

[0086] In addition, the feed box 500 is separately arranged from the sieve body 100, which is convenient for daily maintenance and cleaning. When maintenance or replacement is required, the operator can quickly complete the operation without affecting the normal operation of the entire equipment. In short, the setting of the feed box 500 provides strong support for the efficient and stable operation of the split-type high-frequency vibrating multi-layer sieve, and is an indispensable part of the entire screening system.

[0087] In some examples, the above sieve body 100 includes at least two overlapping sieve layers. Exemplarily, the sieve layers can be selected from, but not limited to, two to five layers.

[0088] As Figure 2 shown, in some examples, the split-type high-frequency vibrating multi-layer sieve further includes: a vibration motor 600, which is arranged at the bottom of the above sieve body 100.

[0089] In this technical solution, the vibration motor 600 is arranged at the bottom of the sieve body 100. Exemplarily, it can be located at the center of the bottom of the sieve body 100. During the operation of the equipment, the vibration motor 600 plays a crucial role. The high-frequency vibration it generates can be quickly transmitted to the sieve body 100, causing the sieve body 100 to vibrate at a specific frequency and amplitude. This vibration mode effectively promotes the stratification and screening of materials on the sieve surface.

[0090] The vibration motor 600 can precisely adjust its vibration frequency, amplitude, and vibration force magnitude through a control system to meet the screening requirements of different materials. For example, for materials with larger particles and heavier specific gravity, the vibration frequency and amplitude can be appropriately increased to enhance the screening effect; for fine and easily agglomerated materials, relatively gentle vibration parameters can be adopted to avoid material clogging of the sieve holes.

[0091] Exemplarily, at the bottom of the sieve body 100, a sturdy mounting bracket and shock-absorbing device can be provided. On the one hand, it can firmly support the vibration motor 600, and on the other hand, it can effectively absorb and reduce the impact force generated during the vibration transmission process, reducing damage to other components of the equipment.

[0092] The split-type high-frequency vibration superimposed sieve further includes a support frame 800. Among them, the sieve body 100, the discharge box 200, the feeding box 500, and the discharge chute 700 are all installed on the support frame 800, and the support frame 800 plays a role in supporting the whole.
