Description

Technical Field

[0001] This invention relates to the field of cooling tower technology, specifically to an energy-saving cooling tower for mining. Background Technology

[0002] In underground mining operations, a large number of equipment require cooling to ensure normal and stable operation. According to the current coal mine work schedule, the cooling effect of equipment hydraulic and air compressor systems directly affects the equipment's lifespan and work efficiency. In order to ensure the cooling effect of the equipment, a large amount of cooling water is needed to cool the equipment.

[0003] Currently, the cooling methods are direct-flow static pressure water or circulating water cooling. After heat exchange in the cooler, the heat generated by the equipment is carried away. The water after heat exchange is directly discharged back to the water tank as wastewater, resulting in a large waste of water resources and a significant burden on the underground drainage system. At the same time, after heat exchange, the internal temperature of the circulating water rises. If the circulating water is not cooled in time, the cooling effect will be poor when the circulating water cools the equipment again, and the equipment is prone to failure due to excessive heat.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1 and Figure 2 A mining energy-saving cooling tower includes a supporting mechanism 1, with multiple axially distributed primary cooling mechanisms 2 inside the supporting mechanism 1, an inward conversion mechanism 3 at the upper end of the supporting mechanism 1, an outward conversion mechanism 4 at the lower end of the supporting mechanism 1, a secondary cooling mechanism 5 installed on the supporting mechanism 1, and a tertiary cooling mechanism 6 installed on the outside of the supporting mechanism 1.

[0024] Please see Figure 3 The primary cooling mechanism 2 includes a casing 21 located inside the bearing mechanism 1. The casing 21 has an internal cavity 23. A bent pipe 22 is fixedly connected to the inner wall of the casing 21. The bent pipe 22 is composed of multiple bow-shaped water pipes. An oil inlet 24 connected to the bent pipe 22 is located inside the casing 21 and at the upper end of the bent pipe 22. A water inlet 25 connected to the internal cavity 23 is located at the upper end of the casing 21. An oil outlet 26 connected to the internal cavity 22 is located at the lower end of the casing 21. A water outlet 27 connected to the internal cavity 23 is located at the lower end of the casing 21.

[0025] At the start of operation, the cooled circulating oil enters the primary cooling mechanism 2 through the inlet switching mechanism 3. Simultaneously, constant-temperature drinking water enters the primary cooling mechanism 2 through the inlet switching mechanism 3, allowing the circulating oil to undergo primary cooling within the primary cooling mechanism 2. The continuous supply of constant-temperature drinking water achieves the purpose of maintaining the cooling of the circulating oil. At the same time, the external secondary cooling mechanism 5 continuously supplies circulating water to the carrier mechanism 1, thereby cooling the outside of the primary cooling mechanism 2 and achieving the effect of secondary cooling. The tertiary cooling mechanism 6 continuously provides air cooling to the surface of the carrier mechanism 1, which is around the primary cooling mechanism 2. The tertiary cooling mechanism 6 also surrounds the outside of the carrier mechanism 1, cooling the inside of the carrier mechanism 1, thus completing the tertiary cooling and achieving the effect of efficient cooling of the circulating oil.

[0026] Please see Figure 1 , Figure 2 and Figure 4 The bearing mechanism 1 includes a load-bearing cylinder 11, an upper cover plate 12 fixedly installed at the upper end of the load-bearing cylinder 11, a lower cover plate 13 fixedly installed at the lower end of the bearing mechanism 1, an adaptation cavity 14 opened inside the bearing mechanism 1, the inner wall of the adaptation cavity 14 adapts to the surface of the primary cooling mechanism 2, the upper cover plate 12 and the lower cover plate 13 close the upper and lower ends of the adaptation cavity 14, a sealing cover 15 fixedly installed on the outer wall of the load-bearing cylinder 11, the sealing cover 15 is distributed circumferentially around the outer wall of the load-bearing cylinder 11 and corresponds one-to-one with the primary cooling mechanism 2, and a gap is left between the sealing cover 15 and the primary cooling mechanism 2.

[0027] Please see Figure 4 The inlet switching mechanism 3 includes a drinking water decomposition ring 31, the lower end of which is fixedly connected to the upper end of the upper cover plate 12. A circulating oil decomposition ring 32 is fixedly connected to the upper end of the drinking water decomposition ring 31. The drinking water decomposition ring 31 and the circulating oil decomposition ring 32 are annular. The diameter of the drinking water decomposition ring 31 is larger than the diameter of the circulating oil decomposition ring 32. A water inlet pipe 34 is fixedly connected to the upper end of the drinking water decomposition ring 31 and is connected to the interior of the drinking water decomposition ring 31. An oil inlet pipe 33 is fixedly connected to the upper end of the circulating oil decomposition ring 32 and is connected to the circulating oil decomposition ring. The internal parts of the circulating oil decomposition ring 32 are interconnected. Multiple first circulating oil transfer pipes 35 are fixedly installed on the outside of the circulating oil decomposition ring 32. The first circulating oil transfer pipes 35 are distributed around the circulating oil decomposition ring 32 and correspond one-to-one with the first-stage cooling mechanism 2. Each first circulating oil transfer pipe 35 is connected to the oil inlet 24 inside the single bend pipe 22. Multiple first water pipes 36 are fixedly installed on the outside of the drinking water decomposition ring 31. The first water pipes 36 are distributed around the drinking water decomposition ring 31 and correspond one-to-one with the first-stage cooling mechanism 2. Each first water pipe 36 is connected to the water inlet 25 inside the single bend pipe 22.

[0028] Please see Figure 4The outflow conversion mechanism 4 includes a drinking water collecting ring 41, the upper end of which is fixedly connected to the lower end of the lower cover plate 13. A circulating oil collecting ring 42 is fixedly connected to the lower end of the drinking water collecting ring 41. The drinking water collecting ring 41 and the circulating oil collecting ring 42 form a ring shape. The diameter of the drinking water collecting ring 41 is larger than the diameter of the circulating oil collecting ring 42. A water outlet pipe 46 is fixedly connected to the lower end of the drinking water collecting ring 41, and the water outlet pipe 46 communicates internally with the drinking water decomposition ring 31. An oil outlet pipe 45 is fixedly connected to the lower end of the circulating oil collecting ring 42, and the oil outlet pipe 45 communicates with the circulating oil collecting ring. The internal parts of the circulating oil collection ring 42 are interconnected. Multiple second circulating oil transfer pipes 44 are fixedly installed on the outside of the circulating oil collection ring 42. The second circulating oil transfer pipes 44 are distributed around the circulating oil decomposition ring 32 and correspond one-to-one with the first-stage cooling mechanism 2. Each second circulating oil transfer pipe 44 is connected to the oil outlet 26 inside the single bend pipe 22. Multiple second water pipes 43 are fixedly installed on the outside of the drinking water collection ring 41. The second water pipes 43 are distributed around the drinking water collection ring 41 and correspond one-to-one with the first-stage cooling mechanism 2. Each second water pipe 43 is connected to the water outlet 27 inside the single bend pipe 22.

[0029] The circulating oil enters the circulating oil decomposition ring 32 through the oil inlet pipe 33. Due to the large unit delivery volume of the circulating oil, it gradually fills the circulating oil decomposition ring 32 and is then transported to each bend 22 through the first circulating oil transfer pipe 35 and the oil inlet 24. Simultaneously, external constant-temperature drinking water enters the drinking water decomposition ring 31 through the water inlet pipe 34. Due to the high water pressure, the constant-temperature drinking water gradually fills the drinking water decomposition ring 31 and is then transported to each receiving cavity 23 through the first water pipe 36 and the water inlet 25. Thus, the constant-temperature drinking water completely surrounds the bend 22 inside the casing 21. The constant-temperature drinking water and the circulating oil inside the bend 22 gradually exchange heat, achieving the purpose of cooling the circulating oil. Because the bend 22 is... Multiple bow-shaped pipes are combined to increase the transport distance of the circulating oil in the bend 22, so that the circulating oil and the constant temperature drinking water can complete the heat exchange to the maximum extent, thereby achieving the effect of cooling the circulating oil. Since there are multiple primary cooling mechanisms 2, the air pressure can be effectively dispersed and fully contacted with the constant temperature cooling water to ensure the maximum heat exchange efficiency. The cooled circulating oil is collected in the circulating oil collection ring 42 through the oil outlet 26 and the second circulating oil transfer pipe 44, and then transported into the equipment through the circulating oil collection ring 42. The constant temperature drinking water after heat exchange enters the drinking water collection ring 41 through the water outlet 27 and the second water pipe 43, and is then transported to the water storage tank through the drinking water collection ring 41.

[0030] Please see Figure 5The secondary cooling mechanism 5 includes a circulating water pipe 51. One end of the circulating water pipe 51 is fixedly connected to the upper end of the upper cover plate 12, and the other end of the circulating water pipe 51 is fixedly connected to the lower end of the lower cover plate 13. The interior of the circulating water pipe 51 is connected to the interior of the adapting cavity 14. A water pump 52 is fixedly installed in the middle of the circulating water pipe 51, and a water chiller 53 is fixedly installed in the middle of the circulating water pipe 51 and below the water pump 52. A first through hole is opened in the middle of the upper cover plate 12, and the upper end interface of the circulating water pipe 51 is connected to the adapting cavity 14 through the first through hole. A second through hole is opened in the middle of the lower cover plate 13, and the lower end interface of the circulating water pipe 51 is connected to the adapting cavity 14 through the second through hole.

[0031] When the circulating oil is cooled in the primary cooling mechanism 2, the circulating cooling water in the circulating water pipe 51 outside the bearing mechanism 1 is continuously pumped in from the top of the upper cover plate 12 by the power of the water pump 52, and then re-enters the circulating water pipe 51 from the bottom of the upper cover plate 12, forming a large circulation. This ensures that the circulating cooling water inside the upper cover plate 12 is always in a flowing state. Because the inner wall of the cavity 14 is in contact with the primary cooling mechanism 2, half of the bend 22 is in contact with the cooling water inside the upper cover plate 12 through the load cylinder 11, thus... When the constant-temperature water inside the cavity 23 exchanges heat with the air distribution inside the bend 22, the constant-temperature water also exchanges heat with the circulating cooling water through the surrounding cylinder 21 and the load-bearing cylinder 11. This avoids the constant-temperature cooling water getting too hot during the heat exchange with the circulating oil, which would result in insufficient cooling effect on the circulating oil. After the heat exchange, the circulating cooling water flows into the circulating water pipe 51 through the lower end of the upper cover plate 12 and is then cooled by the water chiller 53, making it easier for the circulating cooling water to re-enter the upper cover plate 12 for cooling.

[0032] Please see Figure 5 The three-stage cooling mechanism 6 includes a spiral tube 61, which is wound in a loop around the outside of each sealing cover 15. Circulating air ducts 62 are fixedly installed at both ends of the spiral tube 61. A fan 63 is fixedly installed inside the circulating air duct 62. An air cooler 64 is installed inside the circulating air duct 62 and below the fan 63. The side of the spiral tube 61 is in contact with the outside of the load-bearing cylinder 11. The spiral tube 61 is connected by multiple U-shaped tubes.

[0033] When the circulating chilled water flows, the air cooler 64 starts working, thereby circulating the chilled air inside the circulating air duct 62 and the wound tube 61. Because the wound tube 61 is wrapped around the surface of the sealing cover 15, the flowing chilled air flows around the surface of the sealing cover 15. The sealing cover 15 covers the surface of the primary cooling mechanism 2, so the other half of the primary cooling mechanism 2 is located inside the sealing cover 15. After the constant temperature drinking water in the cavity 23 is heated by heat exchange, the heat is transferred to the air between the sealing cover 15 and the primary cooling mechanism 2, so that the air inside the sealing cover 15... As the heat increases, the cold air flowing inside the winding tube 61 continuously carries away the heat inside the sealing cover 15. In other words, the cold air inside the winding tube 61 indirectly absorbs some of the heat from the constant-temperature cooling water in the cavity 23, thereby reducing the temperature of the constant-temperature cooling water to a certain extent. At the same time, the winding tube 61 surrounds the load cylinder 11, further cooling the upper cover plate 12, thus achieving efficient cooling of the circulating oil in a short time. The cold air inside the winding tube 61 is cooled again when it passes through the air cooler 64 after heat exchange.

[0034] Working principle: At the start of operation, the cooled circulating oil enters the first-stage cooling mechanism 2 through the inlet switching mechanism 3. At the same time, constant-temperature drinking water enters the first-stage cooling mechanism 2 through the inlet switching mechanism 3, allowing the circulating oil to undergo primary cooling within the first-stage cooling mechanism 2. The continuous supply of constant-temperature drinking water achieves the purpose of maintaining the cooling of the circulating oil. Meanwhile, the external second-stage cooling mechanism 5 continuously supplies circulating water to the carrier mechanism 1, thereby cooling the outside of the first-stage cooling mechanism 2 and achieving the effect of second-stage cooling. The third-stage cooling mechanism 6 continuously provides air cooling to the surface of the carrier mechanism 1, which is around the first-stage cooling mechanism 2. At the same time, the third-stage cooling mechanism 6 surrounds the outside of the carrier mechanism 1 and cools the inside of the carrier mechanism 1, thus completing the third-stage cooling and achieving the effect of efficient cooling of the circulating oil.
