Description
Technical Field
[0001] This invention relates to the technical field of coal gangue sorting, and more particularly to an intelligent underground gangue sorting device. Background Technology
[0002] When coal mines are mining coal, the coal they extract usually contains a lot of gangue. In order to collect coal blocks independently, sorting devices are usually used to separate coal from gangue, thereby recovering effective coal resources and avoiding the increase in transportation costs caused by transporting gangue and coal together.
[0003] Existing sorting devices employ various methods to separate coal from gangue. For example, a coal gangue sorting device with publication number CN112295924A includes an operating table and a support side frame. A motor is installed on one side of the support side frame, and a sorting structure is provided between the support side frames. The sorting structure includes a conveyor belt, rollers, a sorting plate, and a sliding baffle. A roller is provided on each side of the support side frame, and the two ends of the roller are rotatably connected to the two sides of the support side frame.
[0004] Existing sorting devices typically use filter plates for filtration and screening to separate coal lumps and gangue. This method can only separate larger coal lumps and gangue, while coal lumps and gangue of similar size cannot be effectively distinguished, resulting in poor sorting performance. For example, the aforementioned prior art uses a sorting plate to screen coal lumps and gangue. This screening method can only separate coal lumps or gangue of different sizes, while coal lumps and gangue of similar size will always be mixed together, making it impossible to effectively screen coal lumps and gangue of the same size. At the same time, the dust generated during screening cannot be treated, which can easily cause significant environmental pollution, thus having certain limitations. Therefore, there is an urgent need to design an intelligent sorting device for underground gangue to solve the above problems. Summary of the Invention

Multiple high-pressure jetting components for blowing coal blocks are fixedly installed on the gas collecting box, and each high-pressure jetting component is matched with a corresponding detection and identification module. The screening box is equipped with a discharge inclined plate for conveying coal blocks and gangue.
[0016] This invention provides an intelligent sorting device for underground gangue. It has the following beneficial effects: 1. When separating coal blocks and gangue, this sorting device can efficiently screen larger coal blocks by combining the vibrating components and the screening inclined plate, while smaller gangue and small coal blocks will continue to be conveyed after passing through the screening inclined plate, thus achieving the initial screening of coal blocks and gangue.
[0017] 2. When separating coal and gangue, this sorting device, through the cooperation of multiple guide plates in the ash removal box, can achieve stable falling and transmission of coal and gangue, while avoiding the accumulation of coal and gangue.

[0020] 5. When separating coal and gangue, this sorting device, in conjunction with the screening box, can automatically collect the coal and gangue after they are transported. During the falling process of the coal and gangue, the detection and identification module, in conjunction with the high-pressure airflow generated by the high-pressure jet, can selectively blow and push the lighter coal blocks, so that the coal and gangue are automatically separated during the falling process and stored in different areas within the screening box, thus completing the automatic separation of coal and gangue of the same volume.
[0021] In summary, this invention utilizes vibrating screening to achieve automatic screening of large-volume coal blocks. By employing collision conveying, air blowing, and adsorption, it can not only arrange coal blocks and gangue in sequence but also effectively remove dust from the coal gangue. Furthermore, by using precise detection and identification combined with airflow for sorting, it can achieve automatic sorting of coal blocks and gangue of the same volume with higher sorting accuracy.

Detailed Implementation
[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0026] Example 1: Refer to Figures 1-2 An intelligent sorting device for underground gangue includes a sorting box 1 for sorting coal blocks and gangue. The coal gangue to be sorted usually contains large coal blocks, smaller coal blocks and gangue, and some coal dust is also attached to the coal blocks and gangue. This sorting device is mainly used to sort and collect coal blocks, gangue and dust.
[0027] This sorting device also includes: The vibration sorting unit is installed inside the sorting box 1. The vibration sorting unit uses reciprocating vibration to assist in screening to achieve the initial separation of large-volume coal blocks and small-volume coal gangue. It can greatly improve the screening efficiency, quickly screen out large-volume coal blocks, simplify the process for subsequent precise sorting, and has a high degree of automation, requiring no manual intervention in the initial separation process.
[0028] The ash removal unit is installed inside the sorting box 1. The ash removal unit is used to shake and collect dust during the conveying of coal gangue. It works in conjunction with air blowing and adsorption to achieve efficient ash removal and avoid dust pollution. At the same time, it sorts out the arrangement of coal gangue, so that the coal gangue is arranged in an orderly manner, creating good conditions for subsequent identification and sorting.
[0029] The identification and sorting unit is set inside the sorting box 1. The identification and sorting unit can accurately identify the position and size of coal gangue during transportation, and can realize the automatic sorting of coal blocks and gangue of the same volume. At the same time, it can use targeted airflow to separate the coal blocks from the gangue, solving the problem of difficulty in distinguishing coal gangue of the same volume. The sorting accuracy and sorting efficiency are both higher.
[0030] The side of the sorting box 1 is equipped with an intelligent control host 2, which is used to control the opening and closing and operation status of the vibration sorting unit, the ash removal unit and the identification sorting unit, so as to realize the automated sorting of coal blocks and gangue.
[0031] Example 2: Refer to Figures 2-8 The difference between this embodiment and embodiment one is that the vibration sorting unit includes a screening component and a vibration component. The screening component is provided with a vibration frame 10, and the vibration frame 10 is provided with a screening inclined plate 11 for screening large-volume coal blocks. The vibration component is used to drive the vibration frame 10 to vibrate back and forth, thereby improving the efficiency of the screening component in screening large-volume coal blocks.
[0032] The vibration sorting unit includes a partition plate 9 fixedly installed in the sorting box 1. A servo motor 6 is fixedly installed in the sorting box 1, and a drive roller 7 for driving is provided on the drive end of the servo motor 6. The servo motor 6 and the vibration frame 10 are located on both sides of the partition plate 9. When the servo motor 6 is started, it will drive the drive roller 7 to rotate, and the rotation speed of the drive roller 7 can be controlled by the servo motor 6.
[0033] In a further embodiment, the screening assembly includes a transmission inclined plate 21 fixedly installed in the vibrating frame 10, and the transmission inclined plate 21 is located at the lower part of the screening inclined plate 11. The sorting box 1 is provided with a feed hopper 3 for placing coal blocks and gangue, and the feed hopper 3 is located at the upper part of the screening inclined plate 11. During the screening of coal gangue, the coal gangue to be screened is poured into the sorting box 1 through the feed hopper 3. At this time, the coal gangue will fall onto the screening inclined plate 11 on the vibrating frame 10. At this time, the larger coal blocks in the coal gangue cannot pass through the screening inclined plate 11 and will slide down on the screening inclined plate 11 under the action of gravity. The smaller coal blocks and gangue will fall onto the conveying inclined plate 21 through the screening inclined plate 11 and slide down on the conveying inclined plate 21 under the action of gravity, thus realizing the preliminary separation and screening of large coal blocks and small coal gangue.
[0034] The vibration assembly includes a linkage roller 13 rotatably mounted inside the sorting box 1, a vibration frame 10 slidably mounted between the separator plate 9 and the sorting box 1, a transmission belt 16 for transmitting power is sleeved between the linkage roller 13 and the drive roller 7, a lifting plate 19 is fixedly mounted on the side of the vibration frame 10, and a vibration spring rod 20 for resetting is fixedly mounted between the lifting plate 19 and the top wall of the sorting box 1, a vibration cam 17 is fixedly mounted on the linkage roller 13, and a lifting block 18 that cooperates with the vibration cam 17 is fixedly mounted on the lower part of the lifting plate 19. While the coal gangue is being transported, the servo motor 6 can be started to drive the drive roller 7 to rotate. The rotation of the drive roller 7 will drive the linkage roller 13 to rotate in conjunction with the transmission belt 16. The rotation of the linkage roller 13 will drive the vibration cam 17 on it to rotate. When the vibration cam 17 rotates to contact the lifting block 18, it will lift the lifting block 18 at the same time as it rotates and contacts it. As the lifting block 18 is lifted and rises, it will drive the lifting plate 19 and the vibration frame 10 to move upward synchronously. When the lifting plate 19 moves upward, it will compress the two vibration spring rods 20. When the vibrating cam 17 rotates to a point where it no longer contacts the lifting block 18, the vibrating spring rod 20 will automatically extend and reset, and under the action of gravity of the vibrating frame 10, it will drive the vibrating frame 10 to move down automatically. When the vibrating cam 17 continues to rotate and contacts the lifting block 18, the above process will be repeated, thus realizing the reciprocating vibration of the vibrating frame 10.
[0035] When the vibrating frame 10 reciprocates, it will drive the screening inclined plate 11 and the coal gangue on it to vibrate synchronously, which can drive the coal gangue to turn over and move quickly, thereby breaking up the stacked coal gangue, effectively preventing the coal gangue from getting stuck or piling up when it slides down, and accelerating the movement speed of the coal gangue, thus promoting the screening efficiency of large-volume coal blocks and small-volume coal gangue.
[0036] The vibrating frame 10 is provided with a discharge port for conveying large coal blocks, and the sorting box 1 is provided with a discharge inclined plate 4 that cooperates with the discharge port. When the large coal blocks are conveyed to the end of the screening inclined plate 11, they will be automatically discharged from the discharge port under the action of vibration, and discharged to the outside of the sorting box 1 through the discharge inclined plate 4, so as to realize the automatic conveying and collection of large coal blocks.
[0037] Example 3: Refer to Figures 2-5 as well as Figures 9-13 The difference between this embodiment and embodiment two is that the ash removal unit includes an adsorption component and an ash removal component. The adsorption component is equipped with multiple impellers 28 for generating suction. The ash removal component is used to realize the automatic conveying of coal blocks and gangue, and works with the adsorption component to realize the adsorption and collection of dust inside.
[0038] The adsorption assembly includes a dust collection box 8 fixedly installed in the sorting box 1. The dust collection box 8 is rotatably connected to the drive roller 7. Multiple impellers 28 are fixedly installed on the drive roller 7, and all multiple impellers 28 are located inside the dust collection box 8. A barrier plate 29 for separation is fixedly installed inside the dust collection box 8, and a conductive square tube is provided on the barrier plate 29. As the servo motor 6 drives the drive roller 7 to rotate, the rotation of the drive roller 7 will drive multiple fan impellers 28 to rotate. When the multiple fan impellers 28 rotate, they will generate negative pressure suction in the dust collection box 8, which will draw outside air into the dust collection box 8.
[0039] The ash collection box 8 is equipped with an adsorption box for air intake and a filter air guide box 25 for air exhaust. The adsorption box and the filter air guide box 25 are located on both sides of the baffle plate 29, respectively. The negative pressure suction force acts on the adsorption box, which draws outside air and dust into the dust collection box 8, and then into the right side of the baffle plate 29 (see instruction manual). Figure 11 (As shown in the direction, the same applies to the directions described below), and will be injected into the left side of the baffle plate 29 through the conduction square tube, and will be discharged through the filter air guide box 25. The filter air guide box 25 has the function of filtering dust, so that the dust cannot be discharged through the filter air guide box 25, but will only accumulate on the left side of the baffle plate 29 in the dust collection box 8, thus automatically completing the dust collection.
[0040] The ash collection box 8 is equipped with an ash discharge pipe, which can be opened periodically to discharge and collect the dust in the ash collection box 8.
[0041] In a further embodiment, the ash removal assembly includes an ash removal box 12 fixedly installed in the sorting box 1 for carrying coal blocks and gangue, and the ash removal box 12 cooperates with the conveying inclined plate 21. Multiple guiding inclined plates 26 for conveying coal blocks and gangue are fixedly installed inside the ash removal box 12. Coal blocks and gangue of equal volume will fall into the ash removal box 12 after being conducted by the conveying inclined plate 21. When the coal blocks and gangue fall into the ash removal box 12, they will collide and roll in sequence on multiple guiding inclined plates 26. The rolling action can realize the sequential arrangement of coal blocks and gangue, avoiding their accumulation. At the same time, the collision action can shake off the dust adhering to the coal blocks and gangue, realizing the automatic separation of dust from the coal blocks and gangue.
[0042] The side of the dust removal box 12 is fixedly installed with an adsorption box 23 and an air blowing box 24, and an adsorption tube 22 for adsorbing dust is fixedly connected between the adsorption box 23 and the adsorption box, and an air blowing tube for blowing air is fixedly connected between the air blowing box 24 and the filter air guiding box 25. As coal and gangue fall and collide within the ash removal box 12, air blown out from the filter air guide box 25 is conducted to the air blowing box 24 through the air blowing pipe. At this time, the air blowing box 24 blows horizontal air into the ash removal box 12, while the negative pressure suction generated by the adsorption box acts on the adsorption box 23 through the adsorption pipe 22. Thus, the dust and air are adsorbed into the ash collection box 8 through the adsorption box 23, completing the dust adsorption treatment.
[0043] This allows for the horizontal airflow from the air blowing box 24 into the ash removal box 12. The airflow blows the falling dust, causing it to move laterally within the ash removal box 12. When the dust moves laterally and comes into contact with the adsorption box 23, the adsorption generated by the adsorption box 23 will draw the dust and airflow into the ash collection box 8. This achieves the automatic adsorption, collection, and treatment of dust on coal and gangue by blowing air into the ash removal box 12 through the air blowing box 24 and then removing it through the adsorption box 23.
[0044] The bottom of the ash removal box 12 is equipped with an ash removal filter plate 27 for filtering dust, and the ash removal box 12 is equipped with a discharge box. When the coal and gangue fall to the bottom in the ash removal box 12, they will fall onto the ash removal filter plate 27. At this time, the remaining dust on it will fall to the bottom of the ash removal box 12 through the ash removal filter plate 27 and be discharged and collected periodically through the discharge box, realizing the secondary separation of dust and coal gangue. The coal gangue that cannot pass through the ash removal filter plate 27 will continue to be transported and conducted.
[0045] Example 4: Refer to Figures 2-5 , Figure 9 as well as Figures 14-17The difference between this embodiment and embodiment three is that the identification and sorting unit includes a conveying component and a sorting component. The conveying component is equipped with a fully automatic conveyor belt 32 for conveying coal blocks and gangue. The conveying component is equipped with a detection and identification module 34 for identifying the position and size of coal blocks and gangue. The sorting component and the detection and identification module 34 work together to achieve automatic sorting of coal blocks and gangue.
[0046] The conveying assembly includes a conveying frame 15 fixedly installed inside the sorting box 1, and a fully automatic conveyor belt 32 is provided inside the conveying frame 15. The ash removal box 12 is provided with a conveying opening that cooperates with the fully automatic conveyor belt 32. The coal gangue in the ash box 12 will fall onto the fully automatic conveyor belt 32 through the conveying opening. At this time, the fully automatic conveyor belt 32 will start and drive the coal gangue on it to move, so as to realize the automatic conveying of coal gangue.
[0047] The fully automatic conveyor belt 32 has multiple conveying and distributing troughs 33, and multiple guide plates are provided on the conveying openings. The multiple guide plates cooperate with the multiple conveying and distributing troughs 33. The multiple guide plates are used to limit the coal gangue, so that when the coal gangue enters the fully automatic conveyor belt 32, it will only fall into the conveying and distributing troughs 33, and will not fall between the conveying and distributing troughs 33. In turn, it works with the conveying and distributing troughs 33 to limit the coal gangue, so that the coal gangue can only be conveyed sequentially on the conveying and distributing troughs 33, and will not be squeezed and piled up, which is convenient for subsequent identification and sorting.
[0048] The fully automatic conveyor belt 32 is an existing conveying equipment. It is equipped with a drive motor. The automatic transmission of the fully automatic conveyor belt 32 is achieved through the cooperation of the drive motor, thereby driving the coal gangue on it to be transported. This part is existing technology and will not be described in detail here.
[0049] In a further embodiment, an identification mechanism is provided on the conveying frame 15. The identification mechanism includes a support frame 30 fixedly installed on the conveying frame 15, and multiple detection and identification modules 34 for identifying coal blocks and gangue are fixedly installed on the support frame 30. Through the cooperation of the detection and identification modules 34, the position and size of coal blocks and gangue are accurately detected and identified during the conveying process. When coal gangue is conveyed on the fully automatic conveyor belt 32 and passes through the support frame 30, multiple detection and identification modules 34 on the support frame 30 will detect and identify the coal gangue, thereby accurately determining whether the coal gangue is coal or gangue, and identifying the volume of coal or gangue, which facilitates subsequent sorting.
[0050] If the detection module 34 detects that the material passing through it is a coal block, the detection module 34 will detect the size of the coal block and transmit the data to the intelligent control host 2 to record the position and size of the coal block. Then, during subsequent transportation, the intelligent control host 2 will control the coal block to perform targeted air jet treatment. If the material passing through it is gangue, it will be recorded and will not be treated during subsequent transportation.
[0051] In a further embodiment, the sorting component includes a screening box 14 for collecting coal blocks and gangue, which is fixedly installed in the sorting box 1. A material separating plate 37 for separating coal blocks and gangue is fixedly installed in the screening box 14. An air collecting box 35 is fixedly installed in the screening box 14, and an air blowing pipe 31 for blowing air is fixedly connected between the air collecting box 35 and the filter air guiding box 25. After being conveyed by the fully automatic conveyor belt 32, the coal and gangue fall into the screening box 14, thereby completing the automatic collection of the coal and gangue.
[0052] Multiple high-pressure jetting elements 36 for blowing coal blocks are fixedly installed on the gas collecting box 35, and each high-pressure jetting element 36 is matched with a corresponding detection and identification module 34. The screening box 14 is equipped with a discharge inclined plate 2 5 for conveying coal blocks and gangue. The airflow generated in the filter air guide box 25 is transported to the air collection box 35 through the air blower 31, and after being compressed by the air collection box 35, it is automatically ejected through multiple high-pressure jets 36 to realize the conduction and pressurization of the airflow, so that the airflow ejected through the high-pressure jets 36 has a large impact force.
[0053] When coal and gangue fall into the screening box 14, if gangue is falling, the corresponding high-pressure jetting element 36 will not spray air, and the gangue will automatically fall to the right side of the partition plate 37 inside the screening box 14 (see instruction manual). Figure 17 (as shown in the direction, and the same applies to the directions described below), and discharged through the discharge inclined plate 25; If the falling object is a coal block, the corresponding high-pressure jetting component 36 will spray out a high-pressure airflow under the control of the intelligent control host 2, so that the high-pressure airflow comes into contact with and collides with the coal block, thereby pushing the coal block to the left in the screening box 14, so that the coal block falls to the left side of the partition plate 37 in the screening box 14, and is discharged through the discharge inclined plate 2 5.
[0054] Under the identification function of the detection and identification module 34, the position and size of the conveyed coal block can be detected and identified. When the coal block is detected on the conveying and distribution chute 33, its conveying position will be automatically identified. When the coal block is automatically dropped into the screening box 14, the high-pressure jetting element 36 corresponding to the conveying and distribution chute 33 will spray high-pressure airflow. The high-pressure airflow impacts the coal block and causes it to fall into the left side of the screening box 14 for discharge. The gangue is not treated by the jetting and falls to the right side of the screening box 14, thus completing the automatic sorting of coal blocks and gangue. The sorting is not affected by the size of the two. It can accurately sort coal blocks and gangue of the same size, with high sorting efficiency and higher accuracy.
[0055] The specific working principle of this sorting device is as follows: When screening coal gangue, the coal gangue to be screened is poured into the sorting box 1 through the feed hopper 3. At this time, the coal gangue will fall onto the screening inclined plate 11 on the vibrating frame 10. Larger coal blocks cannot pass through the screening inclined plate 11 and slide down on the screening inclined plate 11 under the action of gravity, while smaller coal blocks and gangue will fall onto the transmission inclined plate 21 through the screening inclined plate 11, thus realizing the preliminary separation and screening of large coal blocks and small coal gangue. While the coal gangue is being conveyed, the servo motor 6 can be started to drive the drive roller 7 to rotate. With the cooperation of the vibration component, the vibration frame 10 and the screening inclined plate 11 reciprocate to vibrate. The screening inclined plate 11 drives the coal gangue on it to vibrate synchronously, thereby breaking up the stacked coal gangue. This effectively prevents the coal gangue from getting stuck or piling up when it slides down, and can accelerate the movement speed of the coal gangue, thus promoting the screening efficiency of large-volume coal blocks and small-volume coal gangue.
[0056] While the servo motor 6 drives the drive roller 7 to rotate, the rotation of the drive roller 7 will drive multiple fan impellers 28 to rotate. The negative pressure suction will draw external air and dust into the dust collection box 8 through the adsorption box and discharge it through the filter air guide box 25. Coal blocks and gangue of equal volume fall into the ash removal box 12 after being conducted by the inclined plate 21. As the coal blocks and gangue fall into the ash removal box 12, they collide and roll on multiple inclined plates 26 in sequence. At the same time as the coal blocks and gangue fall, collide and roll in the ash removal box 12, the air blown out of the filter air box 25 is conducted to the air blowing box 24 through the air blowing pipe. At this time, the air blowing box 24 blows horizontal wind into the ash removal box 12, and the negative pressure suction generated by the adsorption box is applied to the adsorption box 23 through the adsorption pipe 22. Thus, the dust and air are adsorbed into the ash collection box 8 through the adsorption box 23, completing the dust adsorption treatment.
[0057] The coal gangue in the ash box 12 will fall onto the fully automatic conveyor belt 32 through the conveying opening. At this time, the fully automatic conveyor belt 32 will start and drive the coal gangue on it to move. When the coal gangue is conveyed on the fully automatic conveyor belt 32 and passes through the support frame 30, multiple detection and identification modules 34 on the support frame 30 will detect and identify the coal gangue, and then accurately determine whether the coal gangue that has passed through is coal or gangue. When a coal block is detected being conveyed on the conveying and distribution trough 33, its conveying position is automatically identified. When the coal block is conveyed into the screening box 14 and falls automatically, the high-pressure jetting element 36 corresponding to the conveying and distribution trough 33 will spray out a high-pressure airflow. The high-pressure airflow impacts the coal block, causing it to fall into the left side of the screening box 14 for discharge. The gangue is not treated by jetting and falls to the right side of the screening box 14, thereby completing the automatic sorting of coal blocks and gangue.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
