Description

Technical Field

[0001] The invention relates to the field of coal sample mixing and reduction, in particular to a coal sample mixing and reduction integrated machine based on laser burning. Background Art

[0002] Coal samples are small quantities of coal collected according to specific procedures from coal resources (such as coal mines, coal piles, and coal in transit) for laboratory analysis, quality testing, or scientific research to characterize the overall coal. Their primary purpose is to determine coal's calorific value, ash content, volatile matter, sulfur content, and other indicators to determine whether it meets standards for industrial use (e.g., power generation, steelmaking, and chemical raw materials). They also help identify coal types (e.g., lignite, bituminous coal, and anthracite) in geological exploration and analyze the distribution and reserves of coal resources. They provide data support for coal processing (e.g., coal washing and coking) and optimize production processes. They serve as a basis for quality arbitration in coal trading and are also used in environmental regulations (e.g., sulfur emission control).

[0003] Coal sampling must ensure that the sample reflects the overall physical and chemical properties of the coal, avoiding distortions caused by deviations in sampling location, particle size, and other factors. Therefore, the coal sampling and preparation process typically includes crushing, screening, mixing, fractionation, drying, and pulverization. The mixing and fractionation steps are crucial, as they reduce the sample volume while ensuring that the remaining sample accurately represents the composition and properties of the original coal sample.

[0004] Currently, coal sampling and preparation are largely manual processes, with 1g of coal sampled and then burned and ashed in a muffle furnace. The mixing and fractionation process is cumbersome, time-consuming, and requires dedicated personnel. Therefore, a coal sample mixing and fractionation machine based on laser ablation is proposed.

[0034] The following will be combined with the Figure 1 To the attached Figure 10 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort shall fall within the scope of protection of the present invention.

[0035] Example 1:

[0036] like Figures 1-10As shown, the present invention discloses a coal sample mixing and reducing integrated machine based on laser burning, comprising a chassis 1, a stirring and mixing bin 2 is installed on the inner wall of one side of the chassis 1, a feeding port 3 and a discharging port 5 are respectively provided on the upper and lower sides of the stirring and mixing bin 2, and the inner walls on both sides of the discharging port 5 are rotatably connected with an arc-shaped bin cover 6 through a spring hinge, and arc seats 8 are slidably connected to the outer side surfaces of the arc-shaped bin covers 6 on both sides of the inner wall of the chassis 1, and a slide seat 11 is also slidably connected to the two sides of the chassis 1, and a rotating plate 2 46 is rotatably connected between the slide seat 11 and the arc seat 8, and a frame 19 is also slidably provided in the chassis 1, and a rotating shaft 22 is rotatably connected to the frame 19, and a sampler 20 is connected through the rotating shaft 22, and a plurality of sampling cavities 21 are provided on the sampler 20;

[0037] When the side of the sampler 20 with the sampling cavity 21 faces upward, the upper end surface of the sampler 20 is higher than the frame 19, so as to facilitate the fitting of the upper end surface of the sampler 20 with the lower end surface of the arc seat 8, thereby achieving compaction of the coal sample in the sampling cavity 21;

[0038] The frame 19 is in contact with the upper end of the slide seat 11, and the upper end surface of the sampler 20 is in contact with the lower end surfaces of the arc seats 8 on both sides. A driving component is provided in the chassis 1, and the driving component is used to drive the frame 19 to slide in the horizontal and vertical directions. A flip component is provided in the frame 19, and the flip component is used to drive the sampler 20 to flip. A slide rod frame three 39 is connected to the side of the chassis 1 away from the mixing bin 2, and the sliding sleeve on the slide rod frame three 39 is provided with an impact seat 40 that cooperates with the lower end of the sampler 20 to collide. A limiting component is provided in the chassis 1, and the limiting component is used to limit the impact seat 40 at a high position.

[0039] The stirring and mixing bin 2 is equipped with an electric stirring rod 4, and a sampling port 44 is provided on the side of the chassis 1 away from the stirring and mixing bin 2. A waste sample collection bin 45 is also provided below the stirring and mixing bin 2 and installed in the chassis 1, so that the coal sample groups ground to a specified particle size by the grinder can be poured into the stirring and mixing bin 2 through the feed port 3, and the electric stirring rod 4 can mix each group of coal samples evenly. At the same time, the sampling port 44 makes it convenient to take out the prepared coal samples from the chassis 1, and the waste sample collection bin 45 can collect the excess coal samples mixed in the stirring and mixing bin 2, and facilitate the collection of excess coal samples on the sampler 20 during the sample preparation process.

[0040] The front and rear inner walls of the chassis 1 are horizontally connected with a slide frame 7, and the arc seats 8 on both sides are respectively slidably mounted on the outer sides of the front and rear slide frames 7. A spring 9 mounted on the outer side of the slide frame 7 is connected between the arc seat 8 and the inner wall of the chassis 1. The front and rear lower inner walls of the chassis 1 are vertically connected with a slide frame 2 10, and the slide plate seats 11 on both sides are respectively slidably mounted on the outer sides of the front and rear slide frames 10. A spring 2 12 mounted on the outer side of the slide frame 2 10 is connected between the slide plate seat 11 and the inner wall of the chassis 1.

[0041] Such a configuration enables the arc seats 8 on both sides to approach each other and collide with each other under the action of the spring 1 9, and drive the arc-shaped bin cover 6 to overcome the elastic force of the spring hinge between the inner wall of the discharge port 5 and close the discharge port 5. The slide seat 11 moves upward under the action of the spring 2 12, pushing the rotating plate 2 46 to rotate, which can also help the arc seats 8 on both sides to approach each other and drive the arc-shaped bin cover 6 to close the discharge port 5.

[0042] On the contrary, when the slide seat 11 moves downward, the arc seats 8 on both sides can be pulled away from each other through the second rotating plate 46, eliminating the resistance to the arc-shaped bin cover 6, so that the arc-shaped bin cover 6 can rotate under the action of the spring hinge and open the discharge port 5.

[0043] Each slide seat 11 is connected to a vertical tooth plate 13 on both sides, and a tooth 14 is connected to the outer side of the arc-shaped bin cover 6. The tooth 14 engages with the vertical tooth plate 13, so that when the slide seat 11 slides downward and the arc-shaped bin covers 6 on both sides are rotated and opened, the vertical tooth plate 13 can also be pulled downward to drive the vertical tooth plate 13 to engage with the tooth 14 on the outer side of the rotated and opened arc-shaped bin cover 6, thereby driving the arc-shaped bin cover 6 to vibrate and shake, so as to ensure that the coal sample mixed evenly in the mixing bin 2 is smoothly discharged to the sampler 20.

[0044] Example 2:

[0045] like Figures 1-10 As shown, the present invention discloses a coal sample mixing and reducing integrated machine based on laser burning. Compared with the first embodiment, this embodiment discloses the structure of the driving component.

[0046] The driving assembly includes a guide rail 15, a slider 16, a telescopic member 17, and a connecting folding rod 18. The guide rail 15 is set as two parallel front and rear members and is installed on the inner wall of the chassis 1. The slider 16 is slidably sleeved in the guide rail 15. The telescopic member 17 is installed on the slider 16. The connecting folding rod 18 is connected to the upper output end of the telescopic member 17, and the end of the connecting folding rod 18 away from the telescopic member 17 is connected to the frame 19.

[0047] Among them, the guide rail 15 and the slider 16 adopt the existing electric linear guide rail and slider to drive the telescopic part 17, and then drive the connecting folding rod 18 and the frame 19 to slide left and right in the chassis 1. At the same time, the frame 19 can also drive the frame 19 to move up and down through the extension and contraction of the telescopic part 17, and move down through the slide seat 11 on both sides of the frame 19, or the frame 19 can also drive the upper end of the sampler 20 to contact the lower end of the arc seat 8, so as to facilitate the compaction and sampling of the coal sample contained in the sampling cavity 21 on the sampler 20 and dropped from the discharge port 5.

[0048] The specific sampling process is as follows: the control frame 19 moves downward, which can resist the sliding plate seat 11 from moving downward, and pull the arc seats 8 on both sides away from each other through the rotating plate 246, and then the arc bin covers 6 connected by spring hinges on both sides of the discharge port 5 will be opened under the action of elastic force to pour the evenly mixed coal sample in the mixing bin 2 into the sampling cavity 21 of the sampler 20, and then drive the frame 19 to move upward, so that the arc seats 8 on both sides are close to each other, and drive the arc bin covers 6 on both sides to close. At the same time, as the frame 19 moves upward, the upper end of the sampler 20 thereon will be able to fit with the bottom of the arc seats 8 on both sides after the arc seats 8 on both sides are close to each other, so that the coal sample in the sampling cavity 21 is compacted, and then by controlling the left and right reciprocating movement of the frame 19, the bottom of the arc seat 8 can be used to scrape the upper end surface of the sampler 20 to achieve the scraping of excess coal sample on the sampler 20, and the sampling can be realized automatically, avoiding manual work.

[0049] Example 3:

[0050] like Figures 1-10 As shown, the present invention discloses a coal sample mixing and reducing integrated machine based on laser burning. Compared with the second embodiment, this embodiment discloses the structure of the flip component.

[0051] The flip assembly includes a cam 23, a gear 24, a rack 25, a limit slide 26, and a push rod 28. The cam 23 is connected to one end of the rotating shaft 22 extending outside the frame 19, and the gear 24 is mounted on the surface of the rotating shaft 22 inside the frame 19. The rack 25 slides through the frame 19, and both ends of the rack 25 extend outside the frame 19. The rack 25 is above the gear 24 and meshes with the gear 24. The limit slide 26 is connected to the two outer side surfaces of the frame 19. The two side extension ends of the rack 25 are respectively slidably sleeved on the outer side surfaces of the limit slide 26 on both sides. A spring three 27 sleeved on the outside of the limit slide 26 is connected between the extension end of the rack 25 away from the mixing and mixing bin 2 and the frame 19. The push rod 28 is connected to the inner wall of the side of the chassis 1 away from the mixing and mixing bin 2, and cooperates and conflicts with the extension end of the rack 25.

[0052] When the sample preparation is completed, the frame 19 is driven to move to the right through the driving assembly, so that the end of the rack 25 away from the mixing chamber 2 can come into contact with the top rod 28, and then the rack 25 slides in the frame 19 toward the side close to the mixing chamber 2. During the process, the rack 25 can drive the sampler 20 to rotate 180° in the frame 19 by engaging with the gear 24, and then dump the compacted coal sample in the sampling chamber 21, thereby realizing automatic unloading of the prepared coal sample.

[0053] Example 4:

[0054] like Figures 1-10As shown, the present invention discloses a coal sample mixing and reducing integrated machine based on laser burning. Compared with the third embodiment, this embodiment discloses the structure of the limiting component.

[0055] The limiting assembly includes a support plate 29, a slide plate 31, a dial plate 34, and an inclined block 36. The support plates 29 are arranged in two front and rear positions and are located on the front and rear outer sides of the frame 19 and are connected to the bottom of the chassis 1 away from the mixing bin 2. The slide plate 31 is slidably connected to a side of the support plates 29 on both sides that are away from each other. The dial plate 34 is connected to a side of the slide plates 31 on both sides that are close to each other and passes through the support plates 29, extending between the support plates 29 on both sides. The extended end of the dial plate 34 cooperates and contacts with the cam 23. The inclined block 36 is on the upper side of the dial plate 34 and slides through the support plate 29. A rotating plate 38 is rotatably connected between the slide plate 31 and the inclined block 36, and the upper end surface of the inclined block 36 cooperates and contacts with the lower side of the impact seat 40. The two sides of the impact seat 40 also fit and contact with the lower side surfaces of the inclined blocks 36 on both sides.

[0056] During the rotation of the sampler 20, the cam 23 can be driven to rotate through the rotating shaft 22 to resist the downward movement of the dial plate 34, thereby pulling the slide plate 31 downward, and pulling the inclined blocks 36 on both sides away from each other through the rotating plate 38, canceling the limit on the impact seat 40, so that the impact seat 40 can fall from the upper side and impact the sampler 20 with the bottom turned up, so that the coal samples in the sampling chamber 21 turned upside down can all fall, avoiding the coal samples from adhering to and being retained in the sampling chamber 21 due to compaction, further ensuring the stability and reliability of automatic sample preparation and material discharge, and ensuring the degree of automation, avoiding manual operation, and improving the efficiency of sample preparation.

[0057] An opening 33 is provided on the support plates 29 on both sides, and the selector plates 34 on both sides are close to each other and extend between the support plates 29 on both sides through the opening 33 on one side, and slide in the opening 33. An opening 2 35 is provided on the support plates 29 on both sides, and the inclined blocks 36 on both sides are close to each other and extend between the support plates 29 on both sides through the opening 2 35 on one side, and slide in the opening 2 35, so that the selector plates 34 can slide between the support plates 29 on both sides to achieve cooperation with the cam 23, and so that the inclined blocks 36 on both sides are close to each other and can slide between the support plates 29 on both sides to achieve the limitation of the impact seat 40, or cancel the limitation of the impact seat 40.

[0058] The support plate 29 is connected to a limited slide bar 2 30, and both sides of the slide plate 31 are slidably sleeved on the outside of the limited slide bar 2 30. A spring 4 32 sleeved on the outside of the limited slide bar 2 30 is connected between the lower end of the slide plate 31 and the lower end of the limited slide bar 2 30. The support plates 29 on both sides are away from each other and are also connected to a limited slide bar 37 on one side. The inclined block 36 is slidably sleeved on the outside of the limited slide bar 37. A spring 5 41 sleeved on the outside of the slide bar frame 39 is connected between the impact seat 40 and the upper end of the slide bar frame 39. The bottom of the slide bar frame 39 is connected to a limit platform 42 for limiting the impact seat 40, so that the slide plate 31 can be stably moved up and down on the support plate 29 The sliding and inclined blocks 36 can also slide horizontally and stably on the support plate 29, and under the action of the spring four 32, the dial plates 34 on both sides are at the top, so as to facilitate the downward movement of the cam 23 in cooperation with the inclined blocks 36 on both sides. At the same time, the inclined blocks 36 on both sides can also be close to each other under the action of the spring four 32, so as to realize the limitation of the impact seat 40, so that when the dial plate 34 moves downward, the limitation of the impact seat 40 is cancelled, so that the impact seat 40 can move downward at high speed under the action of its own gravity and the elastic force of the spring five 41 to impact the sampler 20 that rotates to the upward bottom, ensuring that the coal samples compacted in the sampling chamber 21 can fall automatically, thereby ensuring the degree of automation.

[0059] The frame 19 is connected to an inclined frame 43 that slides and fits against the side of the impact seat 40. The setting of the inclined frame 43 allows the frame 19 to cooperate with the inclined frame 43 when it is driven to slide toward the side of the mixing bin 2, thereby driving the impact seat 40 to move upward and contact the inclined blocks 36 on both sides to move away from each other until the impact seat 40 moves up to above the inclined blocks 36. Under the action of the spring 432, the inclined blocks 36 on both sides move closer to each other, limiting the impact seat 40 again to facilitate the next impact and discharge. The setting of the limit platform 42 ensures that the impact seat 40 has a lowest point for downward movement, ensuring that the impact seat 40 can effectively fit with the inclined frame 43, move up and reset, and prepare for the next impact. Finally, the coal sample prepared in this way can be ashed using laser burning technology.

[0060] Based on the disclosure and teachings of the above description, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although certain specific terms are used in this description, these terms are only for convenience of description and do not constitute any limitation to the present invention.
