Description

Technical Field

[0001] This utility model relates to the field of cooling towers, specifically to energy-saving cooling towers for mining. Background Technology

[0002] Nitrogen is chemically stable and highly inert under normal conditions, making it resistant to chemical reactions with other substances. Therefore, nitrogen is widely used as a protective gas in industrial production activities, especially in the mining industry, where it plays a crucial role in reducing the oxygen content in mining areas, minimizing air leakage in coal mines, and rendering explosives incapable of detonation, thereby ensuring the safe operation of coal mines.

[0003] Nitrogen generators produce a significant amount of heat during operation, and heat exchange also occurs between modules. Because the explosion-proof housing is a closed space, this heat accumulates inside and cannot dissipate, leading to damage to power devices, reduced reliability, and shortened lifespan. Therefore, a cooling system is essential.

[0004] For example, patent CN220771957U discloses a cooling device, specifically a closed-loop cooling tower for mining, comprising a base, an upper shell, a water tank, a cooling pipe assembly, a spray device, and a hydraulic fan. The base is detachably connected to the upper shell and communicates internally with it. An air inlet is provided on the base, and an air outlet is provided at the top of the upper shell. The water tank is located inside the base, and the cooling pipe assembly is located inside the upper shell for cooling hot water in the mine. The spray device is located above the cooling pipe assembly and sprays cooling water onto it. The hydraulic fan is located at the air outlet at the top of the upper shell and is detachably connected to it.

[0005] The aforementioned patent has no electrical equipment and can be disassembled and transported to the mine for assembly, meeting the transportation and usage requirements in the mine. However, the disadvantage of the aforementioned patent is that it is fixed after installation and cannot be moved for use.

[0006] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

A single-stage, single-suction centrifugal pump is used to extract cooling water from the return water section and transport it to a distribution plate through a return water pipe and a distribution pipe. The distribution plate is generally rectangular in shape, with multiple distribution plates arranged in parallel, and gaps are provided between the multiple distribution plates, with the width of the gaps being greater than half the width of the distribution plate. These gaps are mainly for airflow passage. The distribution pipes are connected to the multiple distribution plates through branch pipes. Air inlets are provided on both the front and rear sides of the lower end of the cooling section. At the same time, a baffle plate is provided on the inner side of the air inlet, with the top inner side of the baffle plate being arc-shaped to prevent cooling water falling on the baffle plate from accumulating. The lower edge of the baffle plate extends beyond the bottom of the air inlet.

[0010] Furthermore, the cooling fan is a nylon fan.

[0011] Furthermore, the single-stage single-suction centrifugal pump for clean water is driven by an explosion-proof three-phase asynchronous motor used in coal mines; both the single-stage single-suction centrifugal pump for clean water and the explosion-proof three-phase asynchronous motor used in coal mines are fixedly installed on a mining flatbed truck.

[0012] Furthermore, the single-stage single-suction centrifugal pump for clean water and the explosion-proof three-phase asynchronous motor for use in coal mines are also equipped with protective shells on their outer sides.

[0013] Furthermore, both the hot water inlet pipe and the cold water outlet pipe extend through the protective shell.

[0014] Furthermore, the bottom of the water distribution plate is provided with several water outlet holes, and the diameter of the water outlet holes gradually increases from the side closer to the water distribution pipe to the side farther away from the water supply pipe.

At the same time, it can effectively reduce the temperature of hot water and reduce thermal pollution to the environment.

[0018] To adapt to the complex working environment underground, it is equipped with a mobile device that can be moved and used via rails in complex environments. The matching electrical equipment has explosion-proof performance and can be used in underground environments containing explosive gases such as methane. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0029] Please see Figure 1-9 The mining energy-saving cooling tower includes a mining cooling device main module 1 and a mining flatbed truck 2;

[0030] The mining flatbed car 2 serves as the base of the entire module, enabling the main module 1 of the mining cooling device to be moved and used via tracks in complex environments.

[0031] The main module 1 of the mining cooling device includes a box 3, which is rectangular in shape, and an exhaust pipe 4 is connected to the top of the box 3; a cooling fan 401 is installed inside the exhaust pipe 4, and a fan protective cover 402 is also installed on the top of the exhaust pipe 4.

[0032] Meanwhile, the cooling fan 401 is a nylon fan;

[0033] The housing 3 includes a water distribution section 301, a cooling section 302, and a return water section 303 arranged sequentially from top to bottom. A water distribution plate 5 is provided in the water distribution section 301, and a heat dissipation coil 6 is provided in the cooling section 302. The inlet and outlet of the heat dissipation coil 6 are respectively connected by a hot water inlet pipe 601 and a cold water outlet pipe 602.

[0034] In this scheme, a return water pipe 501 is connected to the side of the return water section 304, and a water distribution pipe 502 is connected to the outside of the water distribution plate 5. A single-stage single-suction clean water centrifugal pump 503 is installed between the return water pipe 501 and the water distribution pipe 502. The single-stage single-suction clean water centrifugal pump 503 is used to extract the cooling water inside the return water section 304 and transport it to the water distribution plate 5 through the return water pipe 501 and the water distribution pipe 502. The single-stage single-suction clean water centrifugal pump 503 is driven by an explosion-proof three-phase asynchronous motor 504 used in coal mines. Both the single-stage single-suction clean water centrifugal pump 503 and the explosion-proof three-phase asynchronous motor 504 used in coal mines are fixedly installed on the mining flatbed truck 2.

[0035] Meanwhile, in this solution, the single-stage single-suction centrifugal pump 503 and the explosion-proof three-phase asynchronous motor 504 used in coal mines are also provided with protective shells 505 on their outer sides;

[0036] In this design, both the hot water inlet pipe 601 and the cold water outlet pipe 602 extend through the protective shell 505;

[0037] Please see Figure 8-9 In this scheme, the water distribution plate 5 is generally in the shape of a rectangular shell, and multiple water distribution plates 5 are arranged in parallel, and gaps are provided between the multiple water distribution plates 5, and the width of the gap is greater than half the width of the water distribution plate 5; the gap is mainly used for the passage of airflow.

[0038] The water distribution pipe 502 is connected to multiple water distribution trays 5 via branch pipes 507;

[0039] In this scheme, the bottom of the water distribution plate 5 is provided with a number of water outlet holes 506, and the diameter of the water outlet holes 506 gradually increases from the side closer to the water distribution pipe 502 to the side farther away from the water supply pipe 502. Since the pressure on the side of the water distribution plate 5 closer to the water distribution pipe 502 is greater than the pressure on the side of the water supply pipe 502, using a smaller diameter water outlet hole on the side closer to the water distribution pipe 502 is beneficial to reduce the water output of the water outlet hole 506 on this side, thereby making the water droplets flowing out from the bottom of the entire water distribution plate 5 more uniform.

[0040] like Figure 7 As shown, in this scheme, air inlets 7 are provided on both the front and rear sides of the lower end of the cooling section 302; at the same time, a baffle plate 701 is provided on the inner side of the air inlet 7, wherein the top inner side of the baffle plate 701 is arc-shaped to prevent the cooling water falling on the baffle plate 701 from accumulating; at the same time, the lower edge of the baffle plate 701 extends beyond the bottom of the air inlet 7 to prevent water droplets falling from the water distribution plate 5 from flowing out of the air inlet 7.

[0041] In use, the hot water that needs to be cooled enters the radiator coil 6 through the hot water inlet pipe 601; the cooling water falls from the water distribution plate 5 and exchanges heat with the radiator coil 6; the cooling water that has undergone heat exchange falls into the return water section 303 and collects, and then the single-stage single-suction clean water centrifugal pump 503 draws the cooling water inside the return water section 304 and transports it to the water distribution plate 5 through the return water pipe 501 and the water distribution pipe 502; it is used in a cycle.

[0042] At the same time, the cooling fan 401 in the exhaust pipe 4 exhausts air upwards, and the external cold air enters the casing 3 from the air inlet 7. At the same time, the cold air exchanges heat with the heat dissipation coil 6 to remove heat, and the cold air is also cooled to carry away heat through heat exchange.

[0043] This solution should be able to operate normally under the following environmental conditions:

[0044] a) Ambient temperature: 2℃~40℃;

[0045] b) Atmospheric pressure 80 kPa~106 kPa;

[0046] c) Relative humidity ≤ 95% (at 25℃); and take into account condensation on the product surface due to temperature changes;

[0047] d) In situations where the surrounding air contains a mixture of explosive gases such as methane and coal dust, and there is no dripping water, strong turbulence, or vibration;

[0048] e) The air around the installation site is clean, free of oil mist, and well-ventilated;

[0049] This system primarily provides chilled water to the air compressor of a mining nitrogen generator. The 40-degree hot water from the air compressor's aftercooler enters a water storage tank. This system then cools the water to 32 degrees Celsius before it is forced back into the air compressor's aftercooler to further cool the compressor's exhaust and oil. The water then returns to the storage tank after its temperature rises, and this cycle repeats continuously.
