Description

Technical Field

[0001] This application relates to the technical field of ore impurity separation, and in particular to a coal and gangue separation device. Background Technology

[0002] The general sorting methods for coal and gangue can be divided into two main categories: physical methods and chemical methods. Physical methods mainly include density separation, magnetic separation, flotation, and dry separation. Density separation: This method separates coal and gangue based on their density difference using hydraulic or pneumatic methods. Its characteristic is that it utilizes the difference in settling velocity between coal and gangue in a medium to achieve separation; it is simple to operate and low in cost. Magnetic separation: This method utilizes the difference in magnetic properties between coal and gangue using a magnetic separator. Its characteristic is that it has high separation efficiency for coal and gangue with significant magnetic differences and is suitable for large-scale coal preparation plants. Flotation: This method separates coal and gangue by placing them in water and utilizing their specific gravity difference. Its characteristic is that it is suitable for processing fine-grained coal and coal slime; it is low in cost, effective, and simple to operate.

[0003] Dry coal separation primarily relies on the differences in physical properties between coal and gangue, such as density, ash content, texture, hardness, radioactivity, magnetic permeability, and coefficient of friction. Specific methods include manual sorting, pneumatic coal preparation, fluidized bed coal preparation, selective crushing, X-ray transmission, imaging, and magnetic separation. A key advantage of dry coal preparation is that it effectively utilizes coal resources while minimizing environmental impact.

[0004] The conventional coal and gangue separation process involves first identifying the coal and gangue on the conveyor line, then locating them, and finally using high-pressure airflow to blow away the located coal or gangue, thereby achieving separation. However, coal and gangue are heavy and vary in volume, so the same high-pressure airflow does not achieve uniform separation of solid blocks with different volumes and weights, and the separation efficiency needs to be improved. Summary of the Invention

[0005] In order to improve the separation effect of ore impurities, this application provides a coal and gangue separation device.

[0006] This application provides a coal and gangue separation device, which adopts the following technical solution:

[0007] A coal and gangue separation device includes the following modules:

[0008] The positioning data acquisition module acquires the first position data of the first solid object and the second position data of the second solid object on the conveyor line, and triggers the solid object separation module based on the first position data and the second position data.

[0009] A solid separation module includes multiple separation components. Each separation component includes a fixed frame with a separation plate slidably connected to the fixed frame. One end of the separation plate faces the conveyor line. A driving component connects the fixed frame and the separation plate, and the driving component drives the separation plate to slide on the fixed frame. The direction of sliding of the separation plate is towards or away from the conveyor line. The driving component controls the sliding distance and sliding speed of the separation plate.

[0010] The driving component responds to the first position data by driving the separation plate corresponding to the first position data to extend and contact the first solid object to change the movement trajectory of the first solid object; the driving component responds to the second position data or to the disappearance of the first position data by driving the corresponding separation plate to reset and not contact the second solid object.

[0011] The solid output module includes a first storage area and a second storage area. The second storage area is located at one end of the separating plate facing the conveyor line, between the separating plate and the conveyor line, and below the separating plate and the conveyor line.

[0012] Wherein, the first storage area is located at one end of the separation plate away from the conveyor line, or the first storage area is located below the conveyor line;

[0013] The first solid object falls into the first storage area, and the second solid object falls into the second storage area.

[0014] By adopting the above technical solution, the first solid material (such as coal) has its trajectory altered after contacting the separating plate and eventually falls into the first receiving area; the second solid material (such as gangue), because the separating plate resets at an appropriate time, continues to move along the conveyor line and eventually falls into the second receiving area. The coal and gangue separation device achieves a highly efficient and automated separation process, reducing the need for manual intervention and improving production efficiency. Furthermore, due to the use of position data to precisely control the movement of the separating plate, the device also has high separation accuracy and stability. In other operating conditions, the second solid material can also be coal, and the first solid material can be gangue.

[0015] Optionally, when the first storage area is located at one end of the separation plate away from the conveyor line, the driving member responds to the first position data, drives the separation plate corresponding to the first position data to extend and catch the first solid object, and guides the first solid object to roll on the separation plate to the first storage area;

[0016] The positioning data acquisition module also acquires the volume data of the first solid object. In response to the volume data, the solid object separation module controls multiple sequentially adjacent driving components to drive the separation plate to extend and catch the first solid object. The larger the value of the volume data, the more separation plates are driven to extend; the smaller the value of the volume data, the fewer separation plates are driven to extend.

[0017] By employing the above technical solution, the extension operation of the separation plate is optimized based on the position and volume data of the first solid material, ensuring effective separation of coal and gangue. This control method enables more precise control of the separation plate's extension action, thereby improving the efficiency and accuracy of coal and gangue separation. Furthermore, this method can be flexibly adjusted according to the actual conditions of the solid material to adapt to solids of different sizes and shapes.

[0018] Optionally, in response to the first position data, the driving member drives the separation plate corresponding to the first position data to extend and catch the first solid object, guiding the first solid object to roll on the separation plate to the first storage area;

[0019] The positioning data acquisition module also acquires the volume data of the first solid object. In response to the volume data, the solid object separation module controls multiple non-adjacent driving components to drive the separation plates to extend and catch the first solid object. The distance between the two farthest extended separation plates is less than the minimum outer diameter of the first solid object. The larger the volume data value, the larger the distance between the two farthest extended separation plates; the smaller the volume data value, the smaller the distance between the two farthest extended separation plates.

[0020] By adopting the above technical solution and method, the coal and gangue separation device can more flexibly adjust the number and position of the extension of non-adjacent separation plates according to the volume of the first solid material, so as to ensure that the first solid material can be stably caught and guided to the correct receiving area, thereby improving the accuracy and efficiency of the separation process.

[0021] Optionally, the solid separation module controls the driving component to drive the other separation plates, and the driven other separation plates are located between the extended separation plates;

[0022] The extension length of the other separation plates is less than the extension length of the already extended separation plates;

[0023] The solid separation module controls the extension length of the other separation plates in response to the volume data. The larger the volume data value, the larger the extension length of the other separation plates, and the smaller the volume data value, the smaller the extension length of the other separation plates.

[0024] By adopting the above technical solution, when it is necessary to catch and stably guide the first solid material (such as coal) to the first receiving area, in addition to the extension of the separation plate directly corresponding to the first position data, the solid material separation module will also control other separation plates located between the already extended separation plates to extend as well, in order to provide more stable support and guidance. The coal and gangue separation device can more flexibly and accurately adjust the extension strategy and length of the separation plates according to the volume of the first solid material, thereby providing a more efficient and stable separation effect.

[0025] Optionally, after the separation plate that needs to be extended is fully extended, the solid separation module controls the driving component to drive the other separation plates to extend further, with the ends of the other separation plates abutting the lower end of the first solid that has fallen onto the extended separation plate.

[0026] By adopting the above technical solution, in the coal and gangue separation device, when the required extending separation plate is fully extended to catch the first solid material (such as coal), in order to ensure that the first solid material can be stably supported and transported, the solid material separation module further controls the drive component to drive other separation plates to extend, providing more support points; at a certain speed, the first solid material (such as coal) can be scooped up. Even on uneven or bumpy conveyor lines, the first solid material can be adequately supported, reducing the possibility of tumbling or slipping. Therefore, this method enhances the stability of the first solid material on the separation plate by providing additional support points, thereby improving the overall performance and efficiency of the coal and gangue separation device.

[0027] Optionally, the larger the value of the volume data, the faster the driving member drives the separation plate to extend; the smaller the value of the volume data, the slower the driving member drives the separation plate to extend.

[0028] By adopting the above technical solution, the extension speed of the separation plate is dynamically adjusted according to the volume of the first solid material, thereby improving the working efficiency and safety of the coal and gangue separation device.

[0029] Optionally, when the second storage area is located below the conveyor line, the drive unit responds to the first position data and drives the separation plate corresponding to the first position data to extend and push open the first solid object, so that the first solid object has a tendency to move away from the separation plate and fall into the second storage area;

[0030] The positioning data acquisition module also acquires the volume data of the first solid object. In response to the volume data, the solid object separation module controls multiple driving components to drive the separation plates to extend and push open the first solid object. The larger the value of the volume data, the more separation plates are driven to extend, until the number of extended separation plates reaches a preset extension reference value.

[0031] By employing the above technical solution, the solid separation module continuously monitors the position and state of the first solid object and dynamically adjusts the extension number and speed of the separation plates as needed. If the volume data of the first solid object changes or its support becomes unstable during the extension process, the solid separation module will immediately make corresponding adjustments to ensure that the first solid object can be stably pushed open and fall into the second storage area. This not only improves separation efficiency but also enhances the safety and reliability of the entire separation process. By reasonably controlling the extension number and speed of the separation plates, unnecessary risks to equipment or operators can be avoided. This method can effectively adapt to first solid objects of different sizes and achieve a stable and efficient separation process through reasonable control of the extension number and speed of the separation plates.

[0032] Optionally, the larger the value of the volume data, the faster the driving member drives the separation plate to extend; the smaller the value of the volume data, the slower the driving member drives the separation plate to extend.

[0033] By adopting the above technical solution, it is shown that the larger the volume of the first solid object, the faster the separation plate needs to extend to catch and stabilize it. Therefore, the drive component will extend the separation plate at a faster speed. Conversely, if the volume value is small, it indicates that the volume of the first solid object is small, and a faster extension speed is not required. Therefore, the drive component will extend the separation plate at a slower speed. By dynamically adjusting the extension speed of the separation plate according to the volume of the first solid object, the working efficiency and safety of the coal and gangue separation device are improved.

[0034] Optionally, if the number of the separation plates that need to extend is greater than the extension reference value, then the larger the value of the volume data, the fewer the number of adjacent separation plates that the driving member drives to extend simultaneously; the smaller the value of the volume data, the more the number of adjacent separation plates that the driving member drives to extend simultaneously.

[0035] By adopting the above technical solution, when the number of separation plates that need to extend exceeds a certain preset extension reference value, in order to ensure the stability and efficiency of the device, the number of adjacent separation plates that extend at the same time can be adjusted to accommodate the first solid object of different volumes.

[0036] In summary, this application includes at least one of the following beneficial technical effects: dynamically adapting to solids of different volumes, improving separation efficiency and stability, optimizing resource utilization, enhancing safety and reliability, and providing high flexibility.

[0051] The present application will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the application and are not intended to limit the scope of the application.

[0052] This application discloses a coal and gangue separation device, referring to... Figure 1 and Figure 2 It includes the following modules:

[0053] The positioning data acquisition module acquires the first position data of the first solid object 6 and the second position data of the second solid object 7 on the conveyor line 2, and triggers the solid object separation module based on the first and second position data. The first and second position data can be obtained by scanning the mixture of coal and gangue on the conveyor line 2 (such as a conveyor belt) with an X-ray device 1. Based on the different light reflections and textures of the solid objects, the coal and impurities are identified, thereby locating the positions of the coal and gangue on the conveyor line 2, as well as their length or width information at each position—that is, the first and second position data.

[0054] Reference Figure 1 and Figure 3 The solid separation module includes multiple separation components 3. Each separation component 3 includes a fixed frame 31, on which a separation plate 32 is slidably connected. One end of the separation plate 32 is inclined upwards and faces the output port of the conveyor line 2. A driving component 33 connects the fixed frame 31 and the separation plate 32, and the driving component 33 is used to drive the separation plate 32 to slide on the fixed frame 31. The direction of sliding of the separation plate 32 is towards or away from the conveyor line 2; the driving component 33 is used to control the sliding distance and sliding speed of the separation plate 32. (Refer to...) Figure 3 and Figure 4The driving component 33 includes a servo motor, which is fixed to the mounting frame 31. The servo motor drives the sliding of the separating plate 32 via a belt drive. The belt drive includes a synchronous pulley 34, a driven pulley 35, and a belt 36 wound around the outside of the synchronous pulley 34 and the driven pulley 35. The servo motor is coaxially and fixedly connected to the synchronous pulley 34. The conveying direction of the belt 36 is consistent with the sliding direction of the separating plate 32. A fixing clamp 37 is clamped on the belt 36. The mounting frame 31 is fixedly connected to a guide rod 38, which is slidably connected to the mounting frame 31. The section of the guide rod 38 away from the fixing clamp 37 is fixedly connected to the separating plate 32.

[0055] To maintain the stability of the guide rod 38, the four sides of the fixing frame 31, near the receiving end and corresponding to the length of the guide rod 38, are equipped with abutment wheels 39. Since the abutment wheels 39 in the vertical direction are subject to greater influence from gravity and other factors, they are larger. Furthermore, to ensure the abutment wheels 39 can withstand impacts, springs 312 are installed along the vertical direction to buffer them. The remaining wheels on the two opposite sides are smaller and symmetrically distributed, primarily providing stable support for the guide rod 38. The side of the fixing frame 31 away from the receiving end is also equipped with guide limiting components, such as guide limiting grooves that cooperate with the guide rod 38, to ensure the stable movement of the guide rod 38.

[0056] In addition, in order to reduce the degree of friction between the separation plate 32 and the fixing frame 31, a roller 310 is provided on the fixing frame 31 at the sliding part corresponding to the separation plate 32 to convert sliding friction into rolling friction.

[0057] In addition, one end of the separating plate 32 is used to contact the first solid object 6, and the other end, in addition to sliding on the fixing frame 31, also slides onto the guide plate 311 with the same inclination as the separating plate 32, for guiding the first solid object 6.

[0058] In response to the first position data, the driving element 33 drives the separation plate 32 corresponding to the first position data to extend and contact the first solid object 6 to change the movement trajectory of the first solid object 6. In response to the second position data or the disappearance of the first position data, the driving element 33 drives the corresponding separation plate 32 to reset, so that the separation plate 32 does not contact the second solid object 7, thereby not changing the movement trajectory of the second solid object 7.

[0059] Reference Figure 5 The solid output module includes a first storage section 4 and a second storage section 5. The second storage section 5 is located at one end of the separation plate 32 facing the conveyor line 2, between the separation plate 32 and the conveyor line 2, and below the separation plate 32 and the conveyor line 2.

[0060] The first storage section 4 is located at the end of the separation plate 32 away from the conveyor line 2, or, referring to... Figure 6 The first storage section 4 is located below the conveyor line 2.

[0061] The first solid object 6 falls into the first storage area 4, and the second solid object 7 falls into the second storage area 5. The first storage area 4 and the second storage area 5 can be storage boxes or conveyor belts, used to transport the separated first solid object 6 and second solid object 7 to the next node.

[0062] In this application, the first solid material 6 (such as coal) has its trajectory altered after contacting the separating plate 32, eventually falling into the first receiving section 4; this trajectory alteration can be achieved through catching or impacting and lifting. The second solid material 7 (such as gangue), due to the separating plate 32 resetting at an appropriate time, continues to move along the conveyor line 2 and eventually falls into the second receiving section 5. The coal and gangue separation device achieves a highly efficient and automated separation process, reducing the need for manual intervention and improving production efficiency. Furthermore, because position data is used to precisely control the movement of the separating plate 32, the device also has high separation accuracy and stability. In other operating conditions, the second solid material 7 can also be coal, and the first solid material 6 can be gangue.

[0063] Reference Figure 7 and Figure 8 and Figure 9 When the first storage area 4 is located at the end of the separation plate 32 away from the conveyor line 2, the drive unit 33 responds to the first position data, drives the separation plate 32 corresponding to the first position data to extend and catch the first solid object 6, and guides the first solid object 6 to roll on the separation plate 32 to the first storage area 4.

[0064] The positioning data acquisition module also acquires the volume data of the first solid object 6. In response to the volume data, the solid object separation module controls multiple sequentially adjacent driving components 33 to extend the separation plates 32 to catch the first solid object 6. The larger the volume data value, the more separation plates 32 extend; the smaller the volume data value, the fewer separation plates 32 extend. The volume data is estimated using length and width information: volume data = length × width × height, where height is defaulted to 1 and the unit is not included in the calculation. During the process of the separation plates 32 changing the movement trajectory of the solid object, the height has little impact on the extension and retraction length of the separation plates 32; therefore, only the length and width information needs to be considered. In other embodiments, if only the number of extensions of the separation plates 32 is considered, the length parameter can be ignored, setting the length to 1, leaving only the width parameter as an influencing factor. For example, if the width of the first solid object 6 is three times the width of the separation plates 32, then three or more separation plates 32 will extend to support the first solid object 6. If the width of the first solid object 6 is the width of one separation plate 32, then one or more separation plates 32 extend out to receive the first solid object 6.

[0065] Among them, reference Figure 8 The initial position of the separating plate 32 is flush, and its distance from the outlet of the conveyor line 2 is d. Since the second solid object 7 falls directly without operation, the separating plate 32 will only retract to make way when the second solid object 7 is large. In other embodiments, if the total extension length of the separating plate 32 is greater than the total retraction length within a set time period, and both are greater than the corresponding preset values, it indicates that the length of the object to be separated is relatively large. Therefore, d is reduced to decrease the total extension length and the total retraction length, thereby saving energy. Conversely, if the total retraction length is greater than the total extension length, and both are greater than the corresponding preset values, it indicates that the length of the separating plate 32 to be retracted is relatively large, indicating that d is too small and needs to be appropriately increased to reduce the number and length of the retractable separating plates 32. The specific method of increasing or decreasing d can be a step-by-step gradual increase, such as increasing or decreasing by 1 cm or 0.5 cm each time.

[0066] The extension operation of the separation plate 32 is optimized based on the position and volume data of the first solid object 6 to ensure effective separation of coal and gangue. This control method allows for more precise control of the extension action of the separation plate 32, thereby improving the efficiency and accuracy of coal and gangue separation. Furthermore, this method can be flexibly adjusted according to the actual conditions of the solid object to adapt to solid objects of different sizes and shapes.

[0067] Reference Figure 10In response to the first position data, the drive unit 33 drives the separation plate 32 corresponding to the first position data to extend and catch the first solid object 6, guiding the first solid object 6 to roll on the separation plate 32 to the first storage area 4.

[0068] The positioning data acquisition module also acquires the volume data of the first solid object 6. The solid object separation module responds to the volume data and refers to... Figure 11 Multiple non-adjacent driving components 33 are controlled to extend the separation plates 32 to catch the first solid object 6. The distance between the two farthest extended separation plates 32 is less than the minimum outer diameter of the first solid object 6. The larger the volume value, the larger the distance between the two farthest extended separation plates 32, and vice versa. For example, for a first solid object 6 with a width greater than four separation plates 32, the two middle separation plates 32 do not need to extend during the receiving process, and the first solid object 6 can be caught by two or more separation plates 32 on both sides.

[0069] The solid object separation module determines the number and location of non-adjacent separation plates 32 to extend and catch the first solid object 6 based on the volume data. The control strategy ensures that the distance between the two furthest extended separation plates 32 is less than the minimum outer diameter of the first solid object 6, guaranteeing its secure catching and preventing it from slipping between the plates 32. A larger volume data value indicates a larger volume of the first solid object 6, requiring a greater distance between the extended non-adjacent separation plates 32 to accommodate the larger volume. Therefore, the solid object separation module controls more non-adjacent driving elements 33 to extend the separation plates 32, ensuring a sufficiently large distance between them. Conversely, a smaller volume data value indicates a smaller volume of the first solid object 6, requiring fewer or no extended non-adjacent separation plates 32. Therefore, the solid object separation module controls fewer non-adjacent driving elements 33 to extend the separation plates 32, keeping the distance between them relatively small. Using the above method, the coal and gangue separation device can more flexibly adjust the number and position of the extension of the non-adjacent separation plates 32 according to the volume of the first solid 6, so as to ensure that the first solid 6 can be stably caught and guided to the corresponding receiving area, thereby improving the accuracy and efficiency of the separation process.

[0070] Reference Figure 11 and Figure 12 The solid separation module controls the drive unit 33 to drive other separation plates 32, and the driven other separation plates 32 are located between the extended separation plates 32;

[0071] The extension length of other separation plates 32 is less than the extension length of the already extended separation plate 32;

[0072] The solid separation module controls the extension length of other separation plates 32 in response to volume data. The larger the volume data value, the larger the extension length of other separation plates 32, and the smaller the volume data value, the smaller the extension length of other separation plates 32.

[0073] When it is necessary to catch and stably guide the first solid material 6 (such as coal) to the first receiving section 4, in addition to the extension of the separation plate 32 directly corresponding to the first position data, the solid material separation module will also control other separation plates 32 located between the already extended separation plates 32 to extend as well, in order to provide more stable support and guidance. The coal and gangue separation device can more flexibly and accurately adjust the extension strategy and length of the separation plates 32 according to the volume of the first solid material 6, thereby providing a more efficient and stable separation effect.

[0074] Once the required separation plate 32 is fully extended, the solid separation module controls the drive unit 33 to drive the other separation plates 32 to extend further, with the ends of the other separation plates 32 abutting against the lower end of the first solid 6 that has already fallen onto the extended separation plate 32.

[0075] In the coal and gangue separation device, when the required extending separation plate 32 is fully extended to catch the first solid material 6 (such as coal), to ensure that the first solid material 6 can be stably supported and transported, the solid material separation module further controls the drive component 33 to drive other separation plates 32 to extend, providing more support points. At a certain speed, the first solid material 6 (such as coal) can be scooped up. Even on uneven or bumpy conveyor lines 2, the first solid material 6 can be adequately supported, reducing the possibility of tumbling or slipping. Therefore, this method enhances the stability of the first solid material 6 on the separation plate 32 by providing additional support points, thereby improving the overall performance and efficiency of the coal and gangue separation device.

[0076] The larger the volume data value, the faster the extension speed of the separation plate 32 driven by the drive component 33; the smaller the volume data value, the slower the extension speed of the separation plate 32 driven by the drive component 33.

[0077] The extension speed of the separation plate 32 is dynamically adjusted according to the volume of the first solid 6, thereby improving the working efficiency and safety of the coal and gangue separation device.

[0078] Reference Figure 11 and Figure 13 When the second storage area 5 is located below the conveyor line 2, the drive unit 33 responds to the first position data and drives the separation plate 32 corresponding to the first position data to extend and push open the first solid object 6, so that the first solid object 6 has a tendency to move away from the separation plate 32 and fall into the second storage area 5.

[0079] The positioning data acquisition module also acquires the volume data of the first solid object 6. In response to the volume data, the solid object separation module controls multiple driving components 33 to drive the separation plate 32 to extend and push open the first solid object 6. The larger the value of the volume data, the more separation plates 32 are driven to extend, until the number of extended separation plates 32 reaches the preset extension reference value.

[0080] The solid separation module continuously monitors the position and status of the first solid object 6 and dynamically adjusts the extension quantity and speed of the separation plate 32 as needed. If the volume of the first solid object 6 changes or its support becomes unstable during extension, the solid separation module will immediately make corresponding adjustments to ensure that the first solid object 6 can be stably pushed open and fall into the second storage area 5. This not only improves separation efficiency but also enhances the safety and reliability of the entire separation process. By reasonably controlling the extension quantity and speed of the separation plate 32, unnecessary risks to equipment or operators can be avoided. This method can effectively adapt to first solid objects 6 of different sizes and achieve a stable and efficient separation process through reasonable control of the extension quantity and speed of the separation plate 32.

[0081] The larger the volume data value, the faster the extension speed of the separation plate 32 driven by the drive component 33; the smaller the volume data value, the slower the extension speed of the separation plate 32 driven by the drive component 33.

[0082] The larger the volume of the first solid object 6, the faster the separation plate 32 needs to extend to catch and stabilize it. Therefore, the drive unit 33 will extend the separation plate 32 at a faster speed. Conversely, if the volume value is small, it indicates that the first solid object 6 is small, and a faster extension speed is not required. Therefore, the drive unit 33 will extend the separation plate 32 at a slower speed. By dynamically adjusting the extension speed of the separation plate 32 according to the size of the first solid object 6, the working efficiency and safety of the coal and gangue separation device can be improved.

[0083] In other embodiments, if the number of extending separation plates 32 is greater than the extension reference value, for example, the extension reference value is 2, then the larger the volume data value, the fewer adjacent separation plates 32 are driven to extend simultaneously by the driving member 33; conversely, the smaller the volume data value, the more adjacent separation plates 32 are driven to extend simultaneously. When the number of extending separation plates 32 exceeds a certain preset extension reference value, to ensure the stability and efficiency of the device, the number of simultaneously extending adjacent separation plates 32 can be adjusted to accommodate different volumes of the first solid object 6. For example, when the volume is large, two or three plates can be used, positioned approximately symmetrically to the first solid object 6, to receive it. When the volume is small, the first solid object 6 is prone to rolling due to rolling or being affected by bumps, so a larger number of separation plates 32, such as four or five plates, are used to ensure that the first solid object 6 is less likely to fall accidentally.

[0084] Advantages of this application:

[0085] Dynamically adapting to solids of different volumes: By adjusting the extension speed and number of the separation plates 32, as well as the number of adjacent separation plates 32 extending simultaneously, based on the volume data of the first solid 6, this application can dynamically adapt to solids of different sizes, ensuring that they can be stably caught and transported to the correct storage area.

[0086] Improving separation efficiency and stability: By optimizing the extension strategy and speed of the separation plate 32, this application improves the working efficiency of the coal and gangue separation device. Simultaneously, by adjusting the number of adjacent separation plates 32 extending simultaneously, this application can provide more uniform support, preventing solid materials from shifting or rolling during transportation, thereby improving the stability of the entire separation process.

[0087] Optimization of resource utilization: Based on the volume data of the solid material, this application can intelligently control the extension quantity and speed of the separation plate 32, avoiding unnecessary resource waste. This not only reduces energy consumption but also extends the service life of the equipment.

[0088] Enhanced safety and reliability: By monitoring the position and state of solids in real time and dynamically adjusting the extension strategy and speed of the separation plate 32, this application can promptly detect and address potential safety hazards, thereby enhancing the safety and reliability of the entire separation process.

[0089] High flexibility: The control strategy of this application can be flexibly adjusted according to actual needs to adapt to the separation requirements in different scenarios. This makes this application have a wider range of application prospects and adaptability.

[0090] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
