Description

Technical Field

[0001] This invention relates to a cooling mechanism, specifically a coal transportation cooling mechanism for coal mines. Background Technology

[0002] Coal is the most important solid fuel and a type of combustible organic rock. It is formed from abundant vegetation that grew during specific geological eras, gradually accumulating into thick layers under suitable geological conditions, and then being buried underwater or in silt, undergoing natural coalification over long geological periods. Among the world's various geological periods, the Carboniferous, Permian, Jurassic, and Tertiary strata contain the most coal and represent important coal-forming eras. Coal generally has a carbon content of 46-97%, is brown to black, and has a dull to metallic luster. Based on the degree of coalification, coal can be classified into four categories: peat, lignite, bituminous coal, and anthracite.

[0003] During coal mining, coal needs to be crushed to facilitate subsequent transportation. However, after mining and crushing, a large amount of heat accumulates inside the coal. To prevent this heat buildup from causing hazards during mining, traditional techniques involve directly spraying water to cool the coal. However, in practice, traditional water spraying only cools the surface of the coal; the water cannot penetrate the high temperature to the interior, resulting in insufficient cooling of the internal temperature. Based on these reasons, this invention proposes a coal transportation cooling mechanism. Summary of the Invention

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] Example: Figure 1-8 As shown, a coal transportation cooling mechanism for coal mines includes an installation plate 1 with an inverted concave cross-section. A fixed pipe 2 is fixedly connected inside the installation plate 1. Several annular plates 3 are movably connected evenly distributed on the side wall of the fixed pipe 2. Nozzles 4 are fixedly connected between the annular plates 3 of the fixed pipe 2. Several through holes 5 are evenly distributed on the side wall of the fixed pipe 2 inside the annular plates 3. Movable pipes 6 are fixedly connected to the side wall of the annular plates 3 and communicate with the annular plates 3. A horizontal pipe 7 is fixedly connected to the side wall of the movable pipe 6 away from the annular plates 3 and communicates with the inner cavity of the movable pipe 6. A circular shell 8 is movably connected to the side wall of the horizontal pipe 7. Several circular pipes 9 are movably connected evenly distributed on the side wall of the circular shell 8. An insertion pipe 10 is sleeved on the outer wall of the circular pipe 9. Several drainage holes 11 are evenly distributed on the side walls of the insertion pipe 10 and the circular pipe 9, which can realize drainage and cooling operations inside the coal mine.

[0029] Among them, several threaded holes 20 are evenly distributed on the side wall of the circular shell 8, and threads are opened on the outer side wall of the circular tube 9. The circular tube 9 is threadedly connected to the threaded holes 20. Several clamping bolts 21 are evenly distributed on the side wall of the circular shell 8 away from the movable tube 6. The clamping bolts 21 are tightened against the circular tube 9, which facilitates the fixed installation of the circular tube 9 and the insertion tube 10 according to the actual thickness of the coal mine, and the use effect is good.

[0030] Among them, a horizontal plate 22 is fixedly connected to the inner wall of the end of the round tube 9 away from the round shell 8. A square rod 23 is movably connected to the center of the side wall of the horizontal plate 22. A square plate 24 is fixedly connected to the end of the square rod 23 near the round shell 8. The other end of the square rod 23 is fixedly connected to the inner wall of the insertion tube 10. A second spring 25 is sleeved on the square rod 23. One end of the second spring 25 is fixedly connected to the horizontal plate 22. The other end of the second spring 25 is fixedly connected to the square plate 24. This can realize the reset movement between the insertion tube 10 and the round tube 9, reduce the discharge of cooling water from the insertion tube 10 that is not inserted into the coal mine, and reduce water waste.

[0031] Among them, two annular grooves 26 are symmetrically opened on the inner side wall of the annular plate 3, and two annular plates 27 are symmetrically fixedly connected on the inner side wall of the fixed tube 2. The annular plates 27 are movably connected to the annular grooves 26, which facilitates the stable rotation of the annular plate 3 on the side wall of the fixed tube 2.

[0032] The end of the insertion tube 10 away from the circular shell 8 is set in a conical shape, which makes it easy to insert the insertion tube 10 into the coal mine for operation.

[0033] An actuating mechanism is provided on the side wall of the actuating tube 6. The actuating mechanism includes a side plate 12. An arc-shaped rod 13 is movably connected to the side wall of the side plate 12. A flat plate 14 is fixedly connected to one end of the arc-shaped rod 13. The flat plate 14 is fixedly connected to the mounting plate 1. A limit plate 15 is fixedly connected to the other end of the arc-shaped rod 13. A fixing plate 16 is fixedly connected to the side wall of the arc-shaped rod 13. A first spring 17 is sleeved on the side wall of the arc-shaped rod 13. One end of the first spring 17 is fixedly connected to the fixing plate 16. The other end of the first spring 17 is fixedly connected to the side plate 12. This allows the insertion tube 10 and the round tube 9 to be inserted into the coal mine, which facilitates the cooling operation inside the coal mine.

[0034] An installation mechanism is provided on the bottom surface of the mounting plate 1. The installation mechanism includes a base plate 18. The cross-section of the base plate 18 is concave. Several fixing bolts 19 are evenly distributed on the side wall of the base plate 18 away from the center of the mounting plate 1, which facilitates the fixed installation operation between this device and the existing conveying equipment.

[0035] Working Principle: Before use, this invention first connects a suitable length of round tube 9 and insertion tube 10 to the threaded hole 20 on the side wall of the round shell 8 according to the thickness of the coal being conveyed. The round tube 9 is positioned and installed by screwing in the clamping 21. Then, the mounting plate 1 is placed at a suitable position on the coal conveying equipment, allowing the base plate 18 to be inserted into the appropriate position on the conveying equipment. The operator rotates the fixing bolt 19 to tighten it against the conveying equipment, thus fixing the device to the conveying equipment. Then, both ends of the fixing pipe 2 are connected to an external cooling water filling device, allowing cooling water to enter the inner cavity of the fixing pipe 2 and spray out from the nozzle 4. The cooling water in the inner cavity of the fixing pipe 2 enters the annulus through the through hole 5. The cooling water in the inner cavity of plate 3 and movable tube 6 enters the inner cavity of round shell 8 through horizontal pipe 7. During the coal conveying operation, the insertion tube 10 is inserted into the coal mine under the action of gravity and the first spring 17. At this time, the insertion tube 10 drives the square rod 23 to move, and the second spring 25 deforms, so that the drainage hole 11 on the side wall of the insertion tube 10 and the round tube 9 are connected. The cooling water in the inner cavity of round shell 8 is discharged into the coal mine from the drainage hole 11, realizing the cooling operation of the coal mine. Through the conveying equipment, the coal mine can be driven to run, so that the insertion tube 10 can be inserted into the coal mine alternately and continuously, realizing the efficient and convenient cooling operation of coal transportation. Then, the surface of the coal mine is cooled through the nozzle 4, so that the cooling effect of the coal mine is good.
