Description
Technical Field
[0001] This utility model relates to the field of screening equipment technology, and in particular to a multi-stage discharge port control screening enhancement device. Background Technology
[0002] In the mineral processing industry, the coordinated operation of crushing and screening processes is key to improving mineral processing efficiency. Currently, the industry widely adopts multi-stage discharge port control technology to optimize the crushing process. This involves adjusting the discharge port sizes of coarse, medium, and fine crushing equipment in stages (e.g., controlling the coarse crushing discharge port below 170mm) to reduce the overall particle size of the crushed product. However, in actual production, the particle size of the crushed product changes with the adjustment of the multi-stage discharge ports. When the adjustment reduces the particle size, the fixed screen aperture of traditional screening devices becomes relatively too large. While fine-grained ore can pass through the screen, some material that could have passed through a finer screen is easily trapped, resulting in incomplete screening and requiring secondary processing. Conversely, when the particle size increases due to the discharge port adjustment, the fixed screen aperture becomes relatively too small, making it difficult for coarse particles to pass through effectively and quickly, leading to the accumulation of coarse particles on the screen surface and failing to meet the requirements of subsequent grinding processes for raw material precision. Utility Model Content
[0003] The technical problem to be solved by this utility model is that the particle size of the crushed product changes with the adjustment of multiple discharge ports in the existing technology, and the existing device cannot meet the requirements of the subsequent grinding process for the precision of the raw materials. To this end, we propose a multi-stage discharge port control screening enhancement device.
[0004] To achieve the above objectives, this application adopts the following technical solution: a multi-stage discharge outlet control screening and strengthening device, comprising a mounting base plate and a mounting bracket fixedly connected to the upper end of the mounting base plate. A feeding body is mounted on the upper end of the mounting bracket, and a guiding body is shaft-connected to one side of the mounting bracket. A guiding channel is formed on the upper wall of the guiding body, and a collection box is connected to one end of the guiding channel. A coarse filter body, a medium filter body, and a fine filter body are provided on the inner wall of the guiding channel. The coarse filter body is fixedly disposed on the inner wall of the guiding channel, and the medium filter body and the fine filter body are slidably disposed on the inner wall of the guiding channel. An adjusting plate is fixedly connected to the upper wall of both the medium filter body and the fine filter body. A threaded rod is threaded through the upper wall of the guiding body, and the threaded rod is threaded through and connected to the adjusting plate. A motor is fixedly connected to the lower end of the threaded rod, and the motor is mounted on the lower wall of the guiding body. An L-shaped plate is rotatably connected to the upper end of the threaded rod, and the L-shaped plate is fixedly connected to the upper wall of the guiding body.
[0005] Furthermore, the bottom of the material guide channel is inclined, and the lowest point of the inclined bottom of the material guide channel connects to the collection box, which improves the screening efficiency of materials, reduces the manual cleaning work required due to ore accumulation, lowers the manual cleaning cost, and ensures that the screening process can be carried out continuously.
[0006] Furthermore, the two sides of the adjustment plate rest on the upper wall of the material guiding body, which enhances the stability of the adjustment structure, avoids the screening failure caused by the misalignment of the middle filter body 8 and the fine filter body 9, and ensures the normal operation of the screening work.
[0007] Furthermore, when the adjusting plate is attached to the upper wall of the material guiding body, the lower walls of the medium filter body and the fine filter body are attached to the bottom of the material guiding channel, ensuring thorough screening, effectively preventing the mixing of ores of different particle sizes, significantly improving the accuracy of ore classification, and providing raw materials with more uniform particle size for subsequent grinding processes.
[0008] Furthermore, a support frame is fixedly connected to the upper wall of the mounting base plate, a power unit is fixedly connected to the inner wall of the support frame, and an angle control block is fixedly connected to the output end of the power unit.
[0009] Furthermore, the angle control block is attached to the lower wall of the material guide body, which can flexibly match the screening requirements of ores of different particle sizes, effectively avoiding incomplete screening or ore accumulation caused by improper flow rate, and further improving the efficiency and quality of screening.
[0010] The technical effects and advantages of this utility model are as follows: In this invention, when processing fine ore, the adjusting plate descends to fit against the upper wall of the material guide body, and the lower walls of the medium and fine filter bodies fit against the bottom of the material guide channel, forming a three-stage filtration surface together with the coarse filter body. The ore passes through the three filters sequentially. When processing medium ore, the threaded rod drives the adjusting plate to rise, and the fine filter body rises accordingly, with only the coarse and medium filter bodies functioning. When processing coarse ore, the adjusting plate continues to rise, and both the medium and fine filter bodies rise, with only the coarse filter body working. Through mechanical connection and power transmission, the various components achieve coordinated adjustment of filtration levels, angle adjustment, and material conveying, accurately adapting to changes in the particle size of the crushed product and meeting the requirements of subsequent grinding for raw material precision. This solves the problem that the particle size of the crushed product changes with the adjustment of multiple discharge ports, and existing devices cannot meet the requirements of subsequent grinding processes for raw material precision.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0014] Reference Figures 1-5 As shown, in order to address the problem that the particle size of the crushed product changes with the adjustment of multiple discharge ports, and the existing equipment cannot meet the requirements of the subsequent grinding process for raw material precision, the following preferred technical solution is provided: A multi-stage discharge port controlled screening and strengthening device includes a mounting base plate 1, which serves as the foundation of the entire device, providing a stable mounting platform for all components. A mounting bracket 2 is fixedly connected to its upper end, supporting the feed body 3 and the guide body 4, ensuring these two key components maintain a stable relative position during operation. The feed body 3 receives the ore raw material from the crushing stage and smoothly conveys it to the guide body 4 through its own channel. The guide body 4 achieves flexible angle adjustment through a shaft connection with the mounting bracket 2. This connection allows the guide body 4 to rotate within a certain range around the shaft, thereby changing its tilt angle. The guide channel 5 on the upper wall of the guide body 4 is the main site for ore screening. After screening within the guide channel 5, the ore is finally conveyed to the collection box 6 connected at the end. The collection box 6 is responsible for collecting the qualified products after screening, providing raw materials for the subsequent grinding process. The inner wall of the feed channel 5 is sequentially equipped with a coarse filter body 7, a medium filter body 8, and a fine filter body 9. These three filter bodies together constitute a three-stage screening system, capable of classifying and screening ores of different particle sizes. The coarse filter body 7 is fixedly installed on the inner wall of the feed channel 5, maintaining its position, and is mainly used to intercept larger particles of ores in the crushed product. The medium filter body 8 and the fine filter body 9 are slidably installed on the inner wall of the feed channel 5, and their positions can be adjusted according to changes in the particle size of the crushed product. Adjusting plates 10 are fixedly connected to the upper walls of both the medium filter body 8 and the fine filter body 9. A threaded rod 11 is threaded through the upper wall of the feed channel 4, and the threaded rod 11 is threaded through the adjusting plate 10. A motor is fixedly connected to the lower end of the threaded rod 11, which is installed on the lower wall of the feed channel 4 to provide power for the rotation of the threaded rod 11. An L-shaped plate 12 is rotatably connected to the upper end of the threaded rod 11. The L-shaped plate 12 is fixedly connected to the upper wall of the guide body 4, which limits and supports the threaded rod 11, ensuring that the threaded rod 11 remains stable during rotation and does not deviate. The bottom of the feed channel 5 is inclined, with the lowest point of the inclination connecting to the collection box 6. This inclined design fully utilizes gravity; when ore enters the feed channel 5, it slides downwards along the inclined bottom under the pull of gravity, accelerating the flow speed of the ore within the channel and effectively preventing ore accumulation. Simultaneously, the inclined bottom ensures that the screened material can smoothly and automatically flow into the collection box 6, minimizing ore residue in the channel. This improves material screening efficiency, reduces manual cleaning work required due to ore accumulation, lowers manual cleaning costs, and ensures the continuous operation of the screening process. The two sides of the adjusting plate 10 rest against the upper wall of the material guide body 4. This overlapping method allows the adjusting plate 10 to provide vertical support for the intermediate filter body 8 and the fine filter body 9, distributing their weight across the material guide body 4 and avoiding excessive stress on the intermediate filter body 8 and the fine filter body 9, which would otherwise rely solely on their connection to the threaded rod 11. Simultaneously, the portion of the adjusting plate 10 resting against the upper wall of the material guide body 4 restricts the horizontal displacement of the intermediate filter body 8 and the fine filter body 9, ensuring that they remain aligned with the material guide channel 5 during adjustment, preventing ore leakage from the gap between the filter body and the channel wall. This enhances the stability of the adjusting structure, avoids screening failure caused by misalignment of the intermediate filter body 8 and the fine filter body 9, and ensures the normal operation of the screening process. When the adjusting plate 10 is in contact with the upper wall of the feed guide body 4, the lower walls of the intermediate filter body 8 and the fine filter body 9 are in contact with the bottom of the feed guide channel 5. At this time, the intermediate filter body 8 and the fine filter body 9 are completely embedded in the feed guide channel 5. They cooperate with the fixed coarse filter body 7 to form a complete screening surface, covering the entire cross-section of the feed guide channel 5. In this way, when the ore passes through the feed guide channel 5, it must be screened sequentially by the coarse filter body 7, the intermediate filter body 8, and the fine filter body 9, avoiding the direct passage of materials that have not passed through the corresponding filtration levels, and ensuring the comprehensiveness of screening. This ensures thorough screening, effectively prevents the mixing of ores of different particle sizes, significantly improves the accuracy of ore classification, and provides more uniformly sized raw materials for subsequent grinding processes. A support frame 13 is fixedly connected to the upper wall of the mounting base plate 1, providing a stable mounting foundation for the power unit 14. An angle control block 15 is fixedly connected to the output end of the power unit 14, and the angle control block 15 is attached to the lower wall of the material guide body 4. When it is necessary to adjust the tilt angle of the material guide body 4, the power unit 14 starts working, driving the angle control block 15 to move up and down. During the lifting and lowering process, the angle control block 15 pushes or pulls the material guide body 4 to rotate around its axis connection point with the mounting bracket 2, thereby changing the tilt angle of the material guide body 4. When the tilt angle of the material guide body 4 increases, the flow speed of the ore in the material guide channel 5 increases. This state is suitable for processing coarse ore with larger particle size, and can avoid the accumulation of coarse particles in the channel. When the tilt angle decreases, the flow speed of the ore slows down, providing sufficient time for the full screening of fine ore particles, ensuring that the fine ore particles can be accurately screened. It can flexibly match the screening requirements of ores of different particle sizes, effectively avoiding incomplete screening or ore accumulation caused by improper flow rate, and further improving screening efficiency and quality.
[0015] Specifically, the coarse filter body 7, the medium filter body 8, and the fine filter body 9 within the feed channel 5 form a three-stage screening system, working together to complete the screening process. The coarse filter body 7 is fixed to the inner wall of the feed channel 5, serving as the first screening checkpoint. The lifting and lowering adjustment of the medium filter body 8 and the fine filter body 9 is crucial for adapting to ores of different particle sizes: the motor drives the threaded rod 11 to rotate. Since the threaded rod 11 is threadedly connected to the adjusting plate 10, and the two sides of the adjusting plate 10 are restrained by resting against the upper wall of the feed body 4, the rotation of the threaded rod 11 is converted into the up and down movement of the adjusting plate 10, which in turn drives the medium filter body 8 and the fine filter body 9 to slide within the feed channel 5. When processing fine ore, the regulating plate 10 descends to fit against the upper wall of the material guide body 4, and the lower walls of the intermediate filter body 8 and the fine filter body 9 fit against the bottom of the material guide channel 5, forming a three-stage filtration surface together with the coarse filter body 7. The ore passes through the three filters in sequence. When processing medium ore, the threaded rod 11 drives the regulating plate 10 to rise, and the fine filter body 9 is raised accordingly. Only the coarse and intermediate filters are active. When processing coarse ore, the regulating plate 10 continues to rise, and both the intermediate filter body 8 and the fine filter body 9 are raised. Only the coarse filter body is active. The guide body 4 is shaft-connected to the mounting bracket 2, and its tilt angle can be adjusted. It works in conjunction with the power unit 14 and angle control block 15 on the support frame 13 to achieve angle control: the power unit 14 drives the angle control block 15 to rise and fall, and the angle control block 15, in contact with the lower wall of the guide body 4, pushes it to rotate. The bottom of the guide channel 5 is inclined, with its lowest point connecting to the collection box 6. When processing coarse ore, the tilt angle of the guide body 4 is increased to accelerate the ore flow using gravity and prevent coarse particles from accumulating; when processing fine ore, the tilt angle is decreased to slow the flow rate and ensure that fine particles are fully screened. Finally, the screened ore slides along the guide channel 5 into the collection box 6, completing the entire screening process. Through mechanical connections and power transmission, the various components achieve coordinated adjustment of filtration levels, angle adjustment, and material conveying, precisely adapting to changes in the particle size of the crushed product and meeting the requirements of subsequent grinding for raw material precision. This solves the problem that the particle size of the crushed product changes with the adjustment of multiple discharge ports, and existing devices cannot meet the requirements of subsequent grinding processes for raw material precision.

Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
