Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Example 1, referring to Figures 1-4, a mine waste treatment device, including a cylinder body 1, a support frame 2, a conveying frame main body 3 and a conveying pipe 6. The cylinder body 1 is located above the conveyor belt 3. The cylinder body 1 contains lime slurry. The cylinder body 1 is provided with a feed hole 25 for adding lime slurry. A power component unit is arranged inside the cylinder body 1, and a material leakage component is arranged at the bottom of the cylinder body 1. The material leakage component includes a blanking pipe 16, a through hole 17 and a rotating column 18; the blanking pipe 16 is arranged at the bottom of the cylinder body 1, the rotating column 18 is rotatably arranged inside the blanking pipe 16, and the through hole 17 is opened on the rotating column 18 along the axis direction of the rotating column 18.

[0027] Flange plates 15 are symmetrically arranged at the upper edge of the blanking pipe 16. There is a gap between the two flange plates 15, and when the push plate 13 rotates to the position of the flange plate 15, it will fit with the upper surface of the flange plate 15.

[0028] The power component unit includes a motor 22, a transmission shaft 14, a connecting rod 28 and a push plate 13. The motor 22 is installed outside the cylinder body 1. The transmission shaft 14 is rotatably arranged inside the cylinder body 1, and the transmission shaft 14 is connected to the end of the output shaft of the motor 22. Multiple groups of connecting rods 28 are evenly installed on the transmission shaft 14. The push plate 13 is fixed by the connecting rod 28, and the side of the push plate 13 that fits the inner wall of the cylinder body 1 is arranged in an arc shape.

[0029] Gangue is a solid waste generated during coal mining and washing. Now, through research, gangue can be used as a material in the construction industry. Adding it to concrete as an aggregate can improve the strength of the concrete. Therefore, a large amount of gangue in the mining area needs to be piled up on the land. The residual carbon and sulfide in the gangue without any treatment oxidize and release heat, posing a risk of spontaneous combustion. At the same time, the gangue also contains heavy metal ions Pb 2+ , which will have an impact on the environment.

[0030] During the process of the conveying frame main body 3 conveying gangue, since the cylinder body 1 is located above the conveying frame main body 3, a feed hole 25 is arranged on the cylinder body 1. The feed hole 25 is connected to a pipeline, and lime slurry is conveyed into the cylinder body 1 through the feed hole 25. The motor 22 drives the transmission shaft 14 to rotate. During the rotation process, the push plate 13 is driven to move. At the same time, the push plate 13 and the transmission shaft 14 are connected by two connecting rods 28. During the movement of the push plate 13, the lime slurry will pass through between the two connecting rods 28 at the upper end of the push plate 13. At the same time, the lower rotating column 18 will rotate continuously, so that the position of the through hole 17 on the rotating column 18 can be changed. When the through hole 17 is in a vertical state, the lime slurry inside the cylinder body 1 will pass through the through hole 17 and fall on the gangue, evenly wrapping the outside of the gangue particles, and forming a protective layer after hardening.

[0031] In rainy areas, continuous rainwashing may remove the protective layer on the outer surface of coal gangue. Therefore, a spraying device can be connected to the material leakage component to spray lime slurry onto the coal gangue that has been piled up. If the rain is frequent, the spraying frequency can be appropriately increased.

[0032] Example 2, refer to Figures 5-6 , the difference between this embodiment and Embodiment 1 is that a feeding port 26 is provided at a position near the upper end on one side of the cylinder body 1, and a conveying pipe 6 is inclinedly installed outside the feeding port 26. An anti-cracking component is arranged inside the conveying pipe 6. The anti-cracking component includes a feeding bin 4 installed above the conveying pipe 6. A feeding port 12 is provided at the top of the feeding bin 4. Straw fibers are added above the conveying pipe 6. The straw fibers slide down inside the conveying pipe 6 with a relatively high inclination and enter the cylinder body 1 through the feeding port 26; a cam 7 is rotatably arranged at the bottom of the feeding bin 4, and several scraping plates 29 are arranged at the lower end of the cam 7.

[0033] A transmission component is arranged between the cam 7, the transmission shaft 14 and the rotating column 18. The transmission component includes a first transmission gear 19, a second transmission gear 20, a third transmission gear 24 and a chain 5. One end of the cam 7 is connected with a first transmission gear 19 through a round shaft. A third transmission gear 24 is installed on the transmission shaft 14. The second transmission gear 20 is installed on the rotating column 18 through a round shaft. The chain 5 is sleeved outside the first transmission gear 19, the second transmission gear 20 and the third transmission gear 24. An idler gear 23 is arranged on the cylinder body 1 on one side of the third transmission gear 24, and the idler gear 23 cooperates with the chain 5.

[0034] After the lime slurry is evenly sprayed on the outer surface of the coal gangue, after a period of time, cracking and peeling will occur. This is because the lime slurry shrinks in volume due to water evaporation and produces cracks, so the pollution threat during the piling of coal gangue is not completely eliminated.

[0035] For this reason, a conveying pipe 6 is arranged on one side of the cylinder body 1, and straw fibers are supplemented through a feeding device at the top of the conveying pipe 6. Since the conveying pipe 6 is arranged obliquely downward, the straw fibers entering the conveying pipe 6 roll towards the direction close to the cylinder body 1 and finally fall into the cylinder body 1 to be mixed with the lime slurry, so that the lime slurry can better prevent cracking after hardening. During the conveying process, the rotating cam 7 drives the scraping plate 29 at its lower end to assist in the conveying of the straw fibers.

[0036] Example 3, refer to Figures 7-8The difference between this embodiment and embodiment 1 and embodiment 2 is that a leakage pipe 9 is provided at the bottom of the feeding bin 4, a straight plate 10 is slidably provided inside the leakage pipe 9, an arc plate 8 is installed on the top of the straight plate 10, the size of the arc plate 8 matches the size of the upper port of the leakage pipe 9, a column 11 is fixedly installed at the bottom of the straight plate 10, and the column 11 cooperates with the eccentric wheel 7 below.

[0037] Limiting blocks 27 are alternately arranged on the inner walls of the straight plate 10 and the leakage pipe 9 , and the two limiting blocks 27 are located on the same side of the straight plate 10 .

[0038] A cavity 21 is provided on the inner side of the eccentric wheel 7, a feeding pipe 32 is provided on the other end of the eccentric wheel 7, and the feeding pipe 32 is rotatably provided in a reserved hole on one side of the conveying pipe 6, an arc-shaped groove 31 is provided on the bottom of the eccentric wheel 7, a plurality of scrapers 29 are evenly installed on the inner side of the groove 31, a through-type square hole 30 is provided in the area between two adjacent scrapers 29, and vegetable oil is filled in the cavity 21.

[0039] Since the straw fibers are not split and are fluffy, static electricity will be generated during the friction between the straw fibers and the lime powder, which will not only cause the straw fibers to be adsorbed on the top of the conveying pipe 6, but also cause the problem of uneven dispersion of the straw fibers.

[0040] To this end, a cavity 21 is provided on the inner side of the eccentric wheel 7, and the cavity 21 is filled with vegetable oil. A scraper 29 and a square hole 30 are provided at the bottom of the eccentric wheel 7. Whenever the square hole 30 at the bottom of the eccentric wheel 7 rotates to the lowermost end, the vegetable oil inside the cavity 21 will pass through the square hole 30 and contact the straw fiber. At the same time, the scraper 29 pushes the straw fiber to evenly apply the vegetable oil on the outer surface of the straw fiber, thereby solving the problem of uneven dispersion of the straw fiber caused by static electricity.

[0041] The transmission shaft 14, the eccentric wheel 7 and the rotating column 18 are linked by the rotation of the transmission assembly. The structure composed of the first transmission tooth 19, the second transmission tooth 20, the third transmission tooth 24 and the chain 5 realizes the transmission of kinetic energy. At the same time, the setting of the idler wheel 23 can effectively adjust the wrap angle between the third transmission tooth 24 and the chain 5.

[0042] The working principle of the device is: Gangue is a solid waste generated during coal mining and washing. After research, it has been found that gangue can be used as a material in the construction industry. Adding it to concrete as an aggregate can improve the strength of concrete. Therefore, a large amount of gangue needs to be piled up on the land in the mining area. The residual carbon in the gangue without any treatment will oxidize with sulfide to release heat, causing the risk of spontaneous combustion. At the same time, gangue also contains heavy metal ions Pb 2+ , which will have an impact on the environment.

[0043] During the process of transporting coal gangue by the main body 3 of the conveying rack, since the cylinder body 1 is located above the main body 3 of the conveying rack, a feed hole 25 is provided on the cylinder body 1. The feed hole 25 is connected to a pipeline, and lime slurry is conveyed into the interior of the cylinder body 1 through the feed hole 25. The motor 22 drives the transmission shaft 14 to rotate. During the rotation process, the push plate 13 is driven to move. At the same time, the push plate 13 and the transmission shaft 14 are connected by two connecting rods 28. During the movement of the push plate 13, the lime slurry will pass through between the two connecting rods 28 at the upper end of the push plate 13. At the same time, the rotating column 18 at the lower end will rotate continuously, so that the position of the through hole 17 on the rotating column 18 can be changed. When the through hole 17 is in a vertical state, the lime slurry inside the cylinder body 1 will pass through the through hole 17 and fall on the coal gangue, evenly covering the outside of the coal gangue particles, and forming a protective layer after hardening.

[0044] In the case of rainy areas, continuous rain erosion may remove the protective layer on the outer surface of the coal gangue. Therefore, the spraying equipment can be connected to the material leakage component to spray the lime slurry onto the coal gangue that has already been piled up. If the rain is frequent, the spraying frequency can be appropriately increased.

[0045] After the lime slurry is evenly sprayed on the outer surface of the coal gangue, after a period of time, cracking and peeling will occur. This is because the lime slurry shrinks in volume due to water evaporation and produces cracks, so the pollution threat during the stacking of coal gangue is not completely eliminated.

[0046] Therefore, a conveying pipe 6 is provided on one side of the cylinder body 1. Straw fiber is supplemented through a feeding device at the top end of the conveying pipe 6. Since the conveying pipe 6 is arranged obliquely downward, the straw fiber entering the conveying pipe 6 rolls towards the direction close to the cylinder body 1 and finally falls into the cylinder body 1 to be mixed with the lime slurry, so that the lime slurry can better prevent cracking after hardening. During the conveying process, the rotating eccentric wheel 7 drives the scraper 29 at its lower end to assist in the conveying of the straw fiber.

[0047] During the direct contact between the straw fiber and the lime slurry, due to the loose surface of the straw fiber, the straw fiber will show stratification and agglomeration phenomena in the lime slurry.

[0048] Therefore, a feeding bin 4 is provided at the upper end of the conveying pipe 6. The feeding bin 4 is filled with lime powder. When the eccentric wheel 7 at the bottom rotates, it will push the upper column body 11 and the straight plate 10 upward. When the upper arc-shaped plate 8 enters the interior of the feeding bin 4, part of the lime powder enters the leakage pipe 9 and then enters the conveying pipe 6, and will contact and mix with the lower straw fiber. In this way, the fine particles of the lime powder can be adsorbed on the fiber surface, reducing the direct contact between the fibers and playing a certain role in inhibiting their agglomeration.

[0049] Since the straw fibers are not split and are fluffy, static electricity will be generated during the friction between the straw fibers and the lime powder, which will not only cause the straw fibers to be adsorbed on the top of the conveying pipe 6, but also cause the problem of uneven dispersion of the straw fibers.

[0050] To this end, a cavity 21 is provided on the inner side of the eccentric wheel 7, and the cavity 21 is filled with vegetable oil. A scraper 29 and a square hole 30 are provided at the bottom of the eccentric wheel 7. Whenever the square hole 30 at the bottom of the eccentric wheel 7 rotates to the lowermost end, the vegetable oil inside the cavity 21 will pass through the square hole 30 and contact the straw fiber. At the same time, the scraper 29 pushes the straw fiber to evenly apply the vegetable oil on the outer surface of the straw fiber, thereby solving the problem of uneven dispersion of the straw fiber caused by static electricity.

[0051] The transmission shaft 14, the eccentric wheel 7 and the rotating column 18 are linked by the rotation of the transmission assembly. The structure composed of the first transmission tooth 19, the second transmission tooth 20, the third transmission tooth 24 and the chain 5 realizes the transmission of kinetic energy. At the same time, the setting of the idler wheel 23 can effectively adjust the wrap angle between the third transmission tooth 24 and the chain 5.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
