Abstract
Description
Technical Field
[0001] This utility model relates to the field of mixing equipment technology, and in particular to a solvent addition mechanism for the dissociation of organic matter in low- and medium-rank coal. Background Technology
[0002] The organic matter in low- and medium-rank coal typically contains a large amount of volatile matter, aromatic hydrocarbons, and some non-flammable impurities. To improve its energy conversion efficiency, the organic matter in coal needs to be converted into combustible gases, liquid chemicals, or products usable for other industrial applications through a dissociation process. This process usually requires the use of solvents and heating methods to break down the molecular structure of coal, thereby releasing the organic matter, enhancing its combustion performance, or converting it into other high-value-added products.
[0003] Existing coal organic matter dissociation technologies often face the problem of poor mixing between solvent and coal during implementation. Traditional mixing equipment mostly relies on a single mixing method, resulting in uneven mixing and affecting the mixing effect between solvent and coal. Due to the low mixing efficiency, the dissociation process of coal organic matter often takes longer, which increases energy consumption and operating costs.
[0004] The existing equipment is also difficult to clean. Residue easily accumulates on the inner walls of traditional equipment, making cleaning time-consuming and labor-intensive, and leaving behind sources of contamination that affect subsequent use. Most equipment lacks automatic cleaning functions, forcing operators to clean manually, creating an additional workload. Utility Model Content

[0024] Reference Figures 1-3This utility model provides an embodiment of a solvent addition mechanism for the dissociation of organic matter in low-rank coal, comprising a stirring tank 5, a sealing cover 11 on the upper surface of the stirring tank 5, and a mixing mechanism on the upper surface of the sealing cover 11; the mixing mechanism includes a protective box 9 and a second connecting block 10, the lower surface of the protective box 9 being fixedly connected to the upper surface of the sealing cover 11, a motor 12 being fixedly connected inside the protective box 9, a first bevel gear 13 being fixedly connected to the output end of the motor 12, the lower surface of the second connecting block 10 being fixedly connected to the upper surface of the sealing cover 11, and a first connecting rod 14 being rotatably connected inside the second connecting block 10. A second bevel gear 15 is fixedly connected to the outer wall of the first connecting rod 14. A rotating rod 17 is rotatably connected to the outer wall of the first connecting rod 14. An inner stirring rod 22 is fixedly connected to one end of the first connecting rod 14. The outer wall of the rotating rod 17 is rotatably connected to the inside of the sealing cover 11. A third bevel gear 16 is fixedly connected to the outer wall of the rotating rod 17.

An outer stirring rod 23 is fixedly connected to the outer wall of the second connecting plate 21.
[0025] Specifically, the output of motor 12 drives the first bevel gear 13 to rotate, which in turn drives the second bevel gear 15 and the third bevel gear 16 to rotate. This causes the second bevel gear 15 and the third bevel gear 16 to drive the first connecting rod 14 and the rotating rod 17 to rotate in opposite directions. The first connecting rod 14 rotates inside the rotating rod 17. The rotation of the first connecting rod 14 drives the inner stirring rod 22 to rotate. The rotation of the rotating rod 17 drives the third connecting block 18 to move the second connecting plate 21. The second connecting plate 21 then drives the outer stirring rod 23 to move. The counter-rotation of the inner stirring rod 22 and the outer stirring rod 23 improves the mixing effect.
[0026] A scraper 24 is fixedly connected to one end of the second connecting plate 21. The outer wall of the second connecting plate 21 is fixedly connected to the outer wall of the outer stirring rod 23. A second connecting rod 26 is fixedly connected to one end of the scraper 24. A third connecting plate 25 is rotatably connected to one end of the second connecting rod 26. The lower surface of the third connecting plate 25 is rotatably connected to the inner bottom of the mixing tank 5. The upper surface of the third connecting plate 25 is fixedly connected to the lower surface of the inner stirring rod 22.
[0027] Specifically, the movement of the second connecting plate 21 drives the scraper 24 to move, which in turn drives the second connecting rod 26 to move, causing the second connecting rod 26 to rotate on the third connecting plate 25. The movement of the scraper 24 and the second connecting rod 26 scrapes off the deposits on the inner wall of the mixing tank 5, thus achieving the effect of cleaning the inner wall.
[0028] A first connecting block 6 is fixedly connected to the outer surface of the mixing tank 5. A hydraulic rod 7 is fixedly connected inside the first connecting block 6. A first connecting plate 19 is fixedly connected to the output end of the hydraulic rod 7. The lower surface of the first connecting plate 19 is fixedly connected to the upper surface of the sealing cover 11, and the outer wall of the first connecting plate 19 is fixedly connected to the outer wall of the protective box 9.
[0029] Specifically, the output end of the hydraulic rod 7 drives the first connecting plate 19 to move, which in turn drives the sealing cover 11 to move, thereby lifting the inner stirring rod 22 and the outer stirring rod 23 from the mixing tank 5, thus facilitating the cleaning of the interior.
[0030] A support frame 2 is fixedly connected to the outer wall of the mixing tank 5, and a base 1 is fixedly connected to the lower surface of the support frame 2; a solution tank 4 is fixedly connected to the upper surface of the base 1, a high-pressure pump 3 is fixedly connected to one side of the outer wall of the solution tank 4, the lower surface of the high-pressure pump 3 is fixedly connected to the upper surface of the base 1, and a delivery pipe 8 is fixedly connected to the output end of the high-pressure pump 3; a sealing cover 11 is fixedly connected to the outer wall of the delivery pipe 8, a spray pipe 20 is fixedly connected to one end of the sealing cover 11, and the outer wall of the spray pipe 20 is fixedly connected to the inside of the sealing cover 11;
[0031] Specifically, the solution in the solution tank 4 is extracted by starting the high-pressure pump 3 and transported to the inside of the delivery pipe 8, so that the delivery pipe 8 transports the solution to the inner wall of the spray pipe 20, and then sprays it into the inside of the mixing tank 5 through the spray pipe 20. The solution is mixed with the coal by the stirring of the inner stirring rod 22 and the outer stirring rod 23.
[0032] Working principle: First, the output of motor 12 drives the first bevel gear 13 to rotate, which in turn drives the second bevel gear 15 and the third bevel gear 16 to rotate. This causes the second bevel gear 15 and the third bevel gear 16 to drive the first connecting rod 14 and the rotating rod 17 to rotate in opposite directions. The first connecting rod 14 rotates inside the rotating rod 17, which in turn drives the inner stirring rod 22 to rotate. The rotation of the rotating rod 17 then drives the third connecting block 18 to move the second connecting plate 21, which in turn moves the outer stirring rod 23. This stirs the internal coal material. During the stirring process, the high-pressure pump 3 draws the solution from the solution tank 4 and transports it into the conveying pipe 8. The delivery pipe 8 delivers the solution to the inner wall of the spray pipe 20, and then sprays it into the interior of the mixing tank 5 through the spray pipe 20. The solution is mixed with the coal by the stirring of the inner stirring rod 22 and the outer stirring rod 23. The movement of the second connecting plate 21 drives the scraper 24 to move, which in turn drives the second connecting rod 26 to move, causing the second connecting rod 26 to rotate on the third connecting plate 25. The movement of the scraper 24 and the second connecting rod 26 scrapes off the deposits on the inner wall of the mixing tank 5, achieving the effect of cleaning the inner wall. The output end of the hydraulic rod 7 drives the first connecting plate 19 to move, which in turn drives the sealing cover 11 to move, thereby lifting the inner stirring rod 22 and the outer stirring rod 23 out of the mixing tank 5, thus facilitating the cleaning of the interior.
