It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0013] like Figure 1~Figure 2 A general-purpose skid-mounted integrated explosion-proof air-conditioning device for mining is shown, comprising: an explosion-proof air-conditioning body 1, a skid-mounted base 2, a protective frame 3, and an external power supply 4. The explosion-proof air-conditioning body 1, the protective frame 3, and the external power supply 4 are all installed on the skid-mounted base 2, the protective frame 3 is located on the outside of the explosion-proof air-conditioning body 1, and the external power supply 4 is located on one side of the explosion-proof air-conditioning body 1; mounting plates 5 are provided on all four sides of the skid-mounted base 2, and the protective frame 3 is installed on the mounting plate 5 through fixing holes 6 on the mounting plate 5; an explosion-proof control device 7 is provided in the explosion-proof air-conditioning body 1, and the explosion-proof control device 7 is electrically connected to the external power supply 4. The explosion-proof control device 7 is located in the explosion-proof air-conditioning body 1 and serves as a master control device of the explosion-proof air-conditioning body 1, and the external power supply 4 reduces the underground high voltage electricity to 380V for use by the explosion-proof air-conditioning device body.

[0014] The explosion-proof air conditioner body 1 is composed of a body 8, a compressor 9, a condenser 10, an evaporator 11, a first fan 12, and a second fan 13. A partition 14 is provided in the middle of the body 8. The partition 14 divides the interior of the body 8 into an upper evaporation chamber 15 and a lower condensation chamber 16. The condensation chamber 16 is provided with a condenser 10, a liquid storage tank 17, a compressor 9, and a first fan 12. The first fan 12 exhausts hot air to the outside of the body 8 and is generally connected to an exhaust pipe 20. The evaporator 11, the second fan 13, and the explosion-proof control device 7 are all installed in the evaporation chamber 15. An air inlet 18 is provided on one side of the machine body 8. The evaporator 11 and the condenser 10 are located on the inner side of the air inlet 18. The second fan 13 transports cold air to the outside through the air duct 20. The air duct 20 can adopt an elastic flame-retardant and noise-reducing air duct, which can be externally connected to the cold air supply duct 20. The second fan 13 is located in the heat-insulating warehouse 21, and the heat-insulating warehouse 21 is connected to the evaporator 11.

[0015] The evaporator 11 and the condenser 10 both adopt an air-cooling working mode.

[0016] A filter 19 is further provided between the air inlet 18 and the evaporator 11 and the condenser 10 . The filter 19 is mounted at the air inlet 18 of the machine body 8 by magnetic attraction.

[0017] The liquid storage tank 17 contains refrigerant. The liquid inlet pipe of the evaporator 11 and the liquid return pipe of the condenser 10 are both connected to the liquid storage tank 17. An expansion valve 22 and a drying filter 23 are provided on the liquid inlet pipe of the evaporator 11. The liquid return pipe of the evaporator 11 is connected to a gas-liquid separator 24, and the gas-liquid separator 24 is connected to the compressor 9. The compressor 9 is also connected to the liquid inlet pipe of the condenser 10.

[0018] Its working process is: when the power is turned on, the compressor 9 starts first, and the high-temperature and high-pressure refrigerant gas enters the upper part of the condenser 10. After cooling or heat dissipation, it becomes a refrigerant at normal temperature and high pressure. The refrigerant at normal temperature and high pressure flows back to the liquid storage tank 17, and after being dried by the filter, it is reduced in pressure by the expansion valve 22 and enters the lower part of the evaporator 11. After passing through the evaporator 11, the refrigerant evaporates into gas. The gaseous refrigerant enters the compressor 9 after passing through the gas-liquid separator 24 to complete the refrigeration cycle.

[0019] In the above process, the air enters the evaporation chamber 15 of the body 8 after being filtered. When the water vapor in the air enters the evaporation chamber 15, it will condense on the surface of the evaporator 11 when it encounters cold. After gradually accumulating, it naturally flows through the surface of the condenser 10 of the evaporator 11 and evaporates at the condenser 10 to maximize the refrigeration efficiency. The evaporated water vapor is sent to the exhaust system by the first fan 12 along with the circulating air.

[0020] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
