Technical Field
[0001] The present invention relates to the technical field of mine cooling, in particular to a water filtering and cooling circulation system supporting a mine refrigeration device. Background Art
[0002] The mining temperature inside the mine is relatively high, and the continuous high temperature and high humidity environment affects the normal mining of ore. By installing a refrigeration and cooling system in the mine, the temperature and humidity in the mine tunnels can be effectively reduced, the environment in the mine tunnels can be improved, and the work efficiency of the staff can be improved.
[0003] For mines with low mining depths, installing the heat dissipation structure of the refrigeration equipment on the ground and transporting the refrigerant into the tunnel through a pipeline is an efficient means of cooling, while avoiding the need to open a special heat dissipation chamber in the mine.
[0004] However, for mines with greater mining depths, due to the greater depth, the distance of the refrigerant transportation pipeline increases, the internal pressure of the pipeline increases, and the requirements for pipeline laying and material strength increase. At the same time, the long-distance transportation of refrigerants is also affected.
[0005] After searching, patent document CN103912241 B discloses a mine refrigeration and cooling system that is similar to the concept of the present application. Both install the heat dissipation structure in the return air shaft below the ground, which can reduce the length of the conveying pipeline. At the same time, the air flow in the return air shaft can be used to bring out the generated water vapor to avoid affecting the normal construction environment in the mine; however, the heat dissipation structure uses water evaporation to absorb heat and dissipate it to the outside. For high-power refrigeration devices, a matching high-power heat dissipation structure is also required to obtain better heat dissipation effect. For the existing structure, it fails to fully utilize the cooling resources of most mines, and requires the special laying of large-diameter cooling water conveying pipelines, which increases the difficulty of related structural arrangement and also increases the loss of resources. Summary of the Invention

DETAILED DESCRIPTION
[0033] The present invention will be further described below with reference to the accompanying drawings and examples.
[0034] In order to solve the problems mentioned in the background technology, Figure 1 -Attached Figure 7 The mine refrigeration device is equipped with a water filtration cooling circulation system, including a cooling system 100 installed in the tunnel 400 and a heat sink 200 installed between the tunnel 400 and the return air shaft 300. The cooling system 100 is similar to the principle of air conditioning cooling. It realizes heat transfer and exchange by compressing the refrigerant, concentrates the heat in the tunnel 400 to one side of the heat sink 200, and then discharges it to the return air shaft 300 through the heat sink 200; by placing the heat sink 200 between the return air shaft 300 and the tunnel 400, compared with setting it on the ground, the cooling medium transportation distance is short, which is suitable for mines with greater mining depth.
[0035] Specifically, the heat dissipation device 200 includes a heat exchanger 210, a heat exchange circulation pipe 220 and a heat dissipation tower 230. The heat dissipation tower 230 includes a heat dissipation body 231. The upper end of the heat dissipation body 231 is connected to a plurality of hollow heat dissipation fins 234. The heat dissipation fins 234 are made of metal material, and can be made of copper with good heat dissipation effect and corrosion resistance. The inner wall of the heat dissipation body 231 is penetrated by a heat dissipation pipe group 600 connected to the heat exchange circulation pipe 220. During the heat exchange process, the heat on one side of the cooling system 100 is absorbed and exchanged through the heat exchanger 210, and the absorbed cooling medium is transported to the heat dissipation tower 230 through the heat exchange circulation pipe 220. The cooling medium with a certain temperature enters the heat dissipation pipe group 600 in the heat dissipation tower 230 for cooling and heat dissipation, and continuously evaporates in the heat dissipation tower 230 to generate water vapor, and dissipates heat during the evaporation process.
[0036] At the same time, the evaporated water vapor passes through the heat sink 234 and is cooled and dissipated along the heat sink 234. The heat sink 234 here is relatively long, and part of the water vapor is cooled into liquid in the heat sink 234, and then drips into the heat dissipation body 231 to realize liquid recovery, thereby avoiding excessive consumption of water resources and preventing excessive water vapor from being discharged into the return air shaft 300 and causing an impact.
[0037] A first spraying device 700 is further provided at the bottom of the heat dissipation body 231 toward the heat dissipation tube group 600, and the first spraying device 700 is connected to a pumping assembly 800. A liquid cold source collecting container 500 with a built-in purifier is further provided on the outside of the heat dissipation body 231, and the pumping assembly 800 is connected to the liquid cold source collecting container 500; the cold source in the mine includes a solid cold source and a liquid cold source, the solid cold source is a rock or other solid material with a lower temperature, and the liquid cold source is a groundwater flow with a lower temperature; the liquid cold source can be collected by the liquid cold source collecting container 500, and at the same time, the liquid cold source collected in the liquid cold source collecting container 500 is pumped by the pumping assembly 800, and the liquid cold source is pumped out toward one side of the heat dissipation tube group 600 through the first spraying device 700, thereby cooling the surface of the heat dissipation tube group 600 and realizing heat exchange.
[0038] Through the above-mentioned structural design, the structure and resources within the mine can be reasonably utilized, reducing or even eliminating the need to introduce liquid cooling sources. The liquid cooling source in the mine can be purified by the purifier in the liquid cooling source collection container 500, and the low-temperature liquid cooling source in the mine can be reasonably utilized for cooling. This greatly improves the liquid cooling efficiency while maximizing the utilization of the cooling resources in the mine, thereby improving the cooling efficiency.
[0039] The above-mentioned cooling equipment is arranged according to the following steps: a chamber is opened at the position where there is a cold source on the inner wall of the return air shaft 300, and a heat dissipation tower 230 is installed. The heat sink 234 is arranged upward along the cold source. The side walls of the heat sink 234 can be provided with vertical metal sheets to increase the heat exchange area. In the process of water vapor flowing upward along the heat sink 234, it can contact the inner wall of the heat sink 234 to achieve efficient cooling, and the heat is transferred to the cold source on the outside to achieve heat dissipation.
[0040] The cold source for water vapor cooling can be a solid cold source or a liquid cold source. Through the above structural design, the cooling medium in the mine can be fully utilized to cool the water vapor, achieving efficient heat dissipation. At the same time, the water vapor can be condensed and refluxed, minimizing the loss of water resources and avoiding the impact of excessive water vapor overflow on normal construction in the mine.
[0041] The liquid cooling source is introduced into the liquid cooling source collecting container 500 for collection, and the liquid cooling source is directed toward the surface of the heat dissipation tube group 600 through the pumping component 800 and the first spraying device 700 to achieve evaporative heat dissipation. The pumping component 800 pumps the liquid cooling source with a lower temperature into the first spraying device 700, and the liquid cooling source is sprayed toward one side of the heat dissipation tube group 600 through the first spraying device 700 to achieve cooling of the heat dissipation tube group 600. Part of the liquid cooling source evaporates due to the heat and enters the heat sink 234 for cooling, heat exchange and cooling; and part of the liquid cooling source flows back to the heat dissipation body 231 for subsequent cooling.
[0042] In summary, through the above-mentioned structural design, structures such as the heat dissipation tower 230 can be optimized. Arranging the heat dissipation tower 230 in the return air shaft 300 can reduce the distance of heat exchange medium transportation and reduce the transportation pressure of related structural parts; at the same time, by setting up structures such as the liquid cold source collection container 500, the first spraying device 700, and the pumping assembly 800, the mine's own cold source can be fully utilized for efficient heat exchange, thereby improving the efficiency of heat exchange cooling, and efficiently condensing and cooling water vapor, thereby saving water resources and avoiding affecting the normal construction environment in the mine.
[0043] Furthermore, a second spraying device 900 is provided on the inner wall of the heat dissipation body 231 opposite to the heat dissipation tube group 600. The second spraying device 900 is horizontally arranged at the top of the heat dissipation body 231. The second spraying device 900 is connected to the pumping assembly 800 through a pumping pipe 910. The second spraying device 900 can be located at the top position to pump the cooling liquid retained in the heat dissipation body 231 again, and the secondary cooling liquid that has been cooled once is pumped to the top position to exchange heat and cool the heat dissipation tube group 600 again, thereby further improving the efficiency of heat exchange and cooling.
[0044] Specifically, the pumping assembly 800 includes a pumping housing 810, the inner wall of which is sealed and slidably connected to a pumping piston 820, and the two sides of the pumping piston 820 are respectively connected to a first pumping chamber 811 and a second pumping chamber 812, the first pumping chamber 811 and the second pumping chamber 812 are respectively connected to a pumping joint 840 with two built-in one-way valves, and a pumping rod 830 is fixed to the side wall of the pumping piston 820, and the end of the pumping rod 830 passes through the pumping housing 810 and is connected to the first spraying device 700.
[0045] Through the above-mentioned structural design, the pumping piston 820 can be driven to reciprocate synchronously by driving the pumping rod 830 to move back and forth. During the reciprocating movement of the pumping piston 820, the first pumping chamber 811 and the second pumping chamber 812 periodically expand and shrink. Due to the design of the one-way valve in the pumping joint 840, the cooling liquid can be continuously pumped through the first pumping chamber 811 and the second pumping chamber 812.
[0046] The second pumping chamber 812 can pump the external liquid cold source into the heat dissipation body 231 for initial cooling, and the first pumping chamber 811 can re-pump the cooling medium retained in the heat dissipation body 231 to the top for subsequent cooling. The drive control of the pumping component 800 can realize the simultaneous and efficient implementation of the two cooling modes, greatly improving the efficiency of liquid cooling.
[0047] Specifically, the first spraying device 700 is connected to the second pumping chamber 812 through a connecting pipe, and the end of the connecting pipe is connected to one of the pumping joints 840. The liquid cold source collecting container 500 is connected to the second pumping chamber 812 through the cold source delivery pipe 510, and the cold source delivery pipe 510 is connected to another pumping joint 840. The pumping rod 830 is located in the second pumping chamber 812. Through the above structural design, the pumping rod 830 is arranged in the second pumping chamber 812, which can reduce the volume of the second pumping chamber 812 and thus reduce the amount of cooling liquid pumped by the second pumping chamber 812 in a single time. Through the above structural design, the amount of new cooling liquid pumped into the liquid cold source collecting container 500 each time is controlled to be less than the amount of secondary cooling liquid pumped by the second spraying device 900. The amount pumped into the liquid cold source collecting container 500 can match the evaporation consumption, thereby maintaining the relative balance of the liquid in the heat dissipation body 231 and avoiding excessive accumulation of liquid in the heat dissipation body 231 that affects the normal operation of the overall structure.
[0048] A filtering device is also provided inside the pumping joint 840 connected to the first pumping chamber 811. The filtering device can filter some of the sediment in the heat dissipation body 231 to prevent the sediment from entering the internal structure and affecting the normal pumping of the liquid; and the filtering device is located on the outside of the one-way valve, which can form filtering protection on the outside.
[0049] Through the above-mentioned structural design, the liquid can be further purified, which is especially suitable for the liquid cooling source at the bottom of the mine. The liquid cooling source in the mine contains a large amount of metal ions, which will produce scale after heating. The scale accumulates in the heat dissipation body 231 and affects the normal operation of the structure; through the above-mentioned structural design, the scale in the heat dissipation body 231 can be continuously adsorbed and concentrated through the adsorption effect of the first pumping chamber 811, and collected in a centralized manner to avoid deposition in the heat dissipation body 231. Subsequent staff can regularly disassemble and clean the filter device.
[0050] Specifically, the first spraying device 700 includes a reciprocating drive shaft 720, a nozzle 710 is fixed to a first side of the drive shaft 720, a swing block 730 is fixed to a second side, and the pumping rod 830 is linked to the swing block 730 via a linkage rod 731.
[0051] Through the above-mentioned structural design, in the process of driving the rotating shaft 720 to drive the nozzle 710 to swing back and forth, the cooling liquid can be pumped into the top of the heat dissipation tube group 600 in a reciprocating manner to achieve initial cooling; at the same time, in the process of driving the rotating shaft 720 to rotate back and forth, the swing block 730 can be driven to swing back and forth, and finally the outer pumping rod 830 can be driven to move back and forth, thereby realizing the drive control of the pumping assembly 800.
[0052] The pumping assembly 800 can also be driven and controlled solely by a telescopic rod or a reciprocating motor to achieve continuous pumping of the liquid.
[0053] The staff regularly disassembles and oxidizes the heat dissipation body 231 and the pumping assembly 800, cleans the remaining scale and excess cooling liquid, and ensures the continued normal operation of the relevant structures.
[0054] Specifically, the heat pipe group 600 includes a heat dissipation main pipe 610 and several heat dissipation branch pipes 620. A heat dissipation frame 630 is fixed to the lower end of the heat dissipation branch pipe 620. The heat dissipation frame 630 here is also made of metal heat dissipation material, which can efficiently conduct heat in the heat dissipation branch pipe 620. A separate circulation structure or an associated circulation structure can be set in the multiple heat dissipation branch pipes 620 to achieve efficient heat exchange of the cooling medium in the heat dissipation main pipe 610.
[0055] Furthermore, the plurality of heat dissipation racks 630 are connected by a first vibration rod 631 , a second vibration rod 632 is fixed to the lower end of the first vibration rod 631 , and the lower end of the second vibration rod 632 is located on the swing path of the nozzle 710 .
[0056] Through the above-mentioned structural design, during the reciprocating swing of the nozzle 710, the second vibration rod 632 with a certain elasticity can be knocked and interfered, which can drive the multiple heat dissipation racks 630 above to vibrate synchronously. In conjunction with the water flow sprayed toward the outside by the second spraying device 900, it can avoid the accumulation of scale on the surface of the heat dissipation rack 630 to the greatest extent, and avoid affecting the subsequent heat exchange of the heat dissipation rack 630.
[0057] At least two conveying cylinders 232 are connected to the upper end of the heat dissipation body 231, and the upper end of the conveying cylinder 232 is connected to the rectifier box 233. The heat sink 234 is connected to the rectifier box 233. The water vapor can be concentratedly transported to the rectifier box 233 through the conveying cylinder 232 to achieve integration. A one-way fan can be installed in the conveying cylinder 232 to accelerate the steam in the heat dissipation body 231 to be discharged into the rectifier box 233 for integration; the steam in the rectifier box 233 can enter the multiple heat sinks 234 under the action of pressure, and realize efficient heat exchange with the cold source inside the mine in the heat sink 234.
[0058] Specifically, the cooling system 100 includes an evaporator 110, a cooling circulation pipe 120 and a condenser 130. The condenser 130 is fitted with the heat exchanger 210. The evaporator 110 can blow out cool air at a location deep in the tunnel 400. At the same time, under the action of the airflow, the gas is heat exchanged and cooled. The heated refrigerant circulates between the evaporator 110 and the condenser 130 through the cooling circulation pipe 120. The heated refrigerant exchanges heat with the heat exchanger 210 at the condenser 130 to be cooled. The cooled refrigerant flows back to the side of the evaporator 110 for heat exchange. The above actions are repeated to blow low-temperature gas (in the direction of the arrow) toward the depth of the tunnel 400 to achieve efficient cooling.
[0059] Finally, it should be noted that an emergency water supply pipe can be laid between the liquid cold source collection container 500 and the ground, so that when the mine lacks cold source, domestic water can be used for emergency water supply, avoiding the inability to cool down due to lack of cooling water in the liquid cold source collection container 500 and the heat dissipation body 231; only a water supply pipe is needed, the pipe structure is simply arranged, and the domestic water on the ground can be used efficiently, avoiding waste of water resources.
[0060] For mines with excessive liquid cooling sources, holes can be drilled at the bottom of the pool to drain the excess liquid, and the excess overflowed liquid can be diverted to the bottom for rational use, avoiding affecting the normal cooling of structures such as the liquid cooling source collection container 500 and the heat dissipation device 200.
[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
