Description

Technical Field

[0001] The utility model relates to a refrigerated vehicle, in particular to an integrated mobile refrigerated vehicle adapted to high-temperature mine roadways. Background Art

[0002] In mine operations, especially in deep mines, the temperature in the roadway is usually relatively high, possibly reaching over 40 degrees Celsius, which poses severe challenges to the personnel and equipment working in this environment. High temperature not only affects the work efficiency and safety of miners, but also accelerates the aging of equipment and increases the probability of equipment failure. Therefore, how to effectively reduce the temperature in the mine roadway has become an urgent technical problem to be solved.

[0003] Traditional mine refrigeration equipment is mostly installed in a fixed manner and usually consists of components such as a refrigeration unit, a condenser, and an evaporator. Although these devices have a certain effect in reducing the temperature of a local area, their flexibility is insufficient and it is difficult to cope with the changes in different roadway environments. In addition, the traditional equipment is bulky and has poor mobility, making it difficult to be flexibly deployed in the complex terrain of the mine, resulting in limited refrigeration effect.

[0004] There are also some mobile refrigeration devices on the market currently, but they often cannot well adapt to the high-temperature and high-humidity environment of mines. For example, the refrigeration capacity of these devices may not be sufficient to cope with the continuously high-temperature environment in the mine, or the performance of the devices will significantly decline after long-term use. At the same time, the existing mobile refrigeration devices also have deficiencies in air circulation and heat exchange efficiency, and cannot fully exert the refrigeration effect. Content of the Utility Model

[0005] To solve the above problems, the following technical solutions are proposed:

[0006] An integrated mobile refrigerated vehicle adapted to high-temperature mine roadways includes a refrigeration system and a drive system. The refrigeration system includes a refrigeration unit and a blower group, and the drive system includes a chassis. A cab is provided at the front end of the chassis, and the refrigeration system is arranged at the rear end of the chassis. Heat transfer between the refrigeration unit and the outside is achieved through the blower group.

[0007] Further, the blower group includes a blower box. A blower is arranged in the blower box. An air outlet is provided on the side of the blower box close to the cab, and an air inlet is provided on one side of the blower box. An evaporator is arranged in the blower box. The air inlet end of the blower is communicated with the air inlet, and the air outlet end of the blower is communicated with the air outlet.

[0008] Further, the air outlet is circular, the air inlet is rectangular, there are two air outlets, and there is one air inlet.

[0009] Further, it further includes a wind guiding cloth tube, one end of which is installed on the air outlet, and annular section rings are evenly and equidistantly arranged inside the wind guiding cloth tube.

[0010] Further, the refrigeration unit includes a refrigeration machine case, a condenser, a throttling device, an evaporator, and a compressor. The condenser, the throttling device, and the compressor are arranged inside the refrigeration machine case, and a heat dissipation port is opened at one end of the refrigeration machine case away from the cab.

[0011] Further, a heat dissipation fan is arranged on the heat dissipation port.

[0012] Further, the condensers are arranged on both sides inside the refrigeration machine case. Box doors are opened on both sides of the refrigeration machine case, and the box doors are hinged to the refrigeration machine case. A spraying device is arranged inside the refrigeration machine case. The spraying device includes spraying heads, spraying pipes, and valves. The water inlet of the spraying pipe is arranged on one side of the refrigeration unit, and a flexible water delivery pipe is connected to the water inlet end of the spraying pipe.

[0013] The beneficial effects of the present utility model are as follows:

[0014] By integrating the refrigeration system and the driving system on a chassis, an integrated design is formed, making the overall structure of the equipment compact. The refrigeration system is installed at the rear end of the chassis, while the cab is located at the front end of the chassis, reasonably distributing the weight and space of the equipment. This layout not only makes the movement of the equipment in the mine roadway more flexible, but also can easily cope with the complex terrain in the roadway, improving the applicability and operation convenience of the equipment.

[0015] The refrigeration system of the equipment includes a refrigeration unit and a blower unit. Through the blower unit, heat transfer between the refrigeration unit and the outside world is realized, effectively improving the refrigeration efficiency. The blower unit quickly takes the heat from the outside away from the refrigeration unit, maintaining the efficient working state of the refrigeration unit, so as to provide a continuous and stable cooling effect in the high-temperature roadway environment. This design ensures the long-term refrigeration ability of the equipment in the high-temperature environment, significantly improving the mine operation environment.

[0016] Each component in the refrigeration system, such as the condenser, compressor, etc., adopts a durable design suitable for high-temperature environments and can operate stably in the high-temperature roadway for a long time. This design greatly reduces equipment failures caused by high temperature, extends the service life of the equipment, reduces maintenance costs, and improves the reliability of the equipment.

[0017] Since the hot air outlet of the refrigeration unit discharges hot air into the non-refrigerated area for a long time, the temperature of the non-refrigerated area is very high. At the same time, various devices such as the compressor in the refrigeration unit also generate a large amount of heat during operation. Excessive temperature will cause various devices such as the compressor in the refrigeration unit to stop operating. The refrigeration unit is cooled by the spraying device to ensure that the refrigeration unit can continue to work. Description of the Drawings

[0025] The following further describes the present utility model in conjunction with the drawings of the specification:

[0026] An integrated mobile refrigeration vehicle adapted to high-temperature mine roadways, comprising a refrigeration system and a drive system. The refrigeration system includes a refrigeration unit and a blower unit, and the drive system includes a chassis. A cab 1 is provided at the front end of the chassis, and the refrigeration system is arranged at the rear end of the chassis. Heat transfer between the refrigeration unit and the outside is achieved through the blower unit. The blower unit includes a blower box 21, in which a blower is arranged. An air outlet 22 is provided on the side of the blower box 21 close to the cab 1, and an air inlet 23 is provided on one side of the blower box 21. An evaporator 41 is arranged in the blower box 21. The air inlet end of the blower is communicated with the air inlet 23, and the air outlet end of the blower is communicated with the air outlet 22. The air outlet 22 is circular, the air inlet 23 is rectangular, there are two cold air outlets, and there is one air inlet 23. It also includes a wind guiding cloth tube, one end of which is installed on the air outlet 22, and circular ring-shaped joint rings are evenly arranged at equal intervals inside the wind guiding cloth tube. The refrigeration unit includes a refrigeration machine box 31, a condenser 42, a throttling device, an evaporator 41, and a compressor. The condenser 42, the throttling device, and the compressor are arranged in the refrigeration machine box 31. A heat dissipation port 32 is opened at one end of the refrigeration machine box 31 away from the cab 1. A heat dissipation fan is arranged on the heat dissipation port 32. The condenser 42 is arranged on both sides inside the refrigeration machine box 31. Box doors are provided on both sides of the refrigeration machine box 31, and the box doors are hinged to the refrigeration machine box 31. A spraying device is arranged in the refrigeration machine box 31, and the spraying device includes a spray head 5, a spray pipe, and a valve. The water inlet of the spray pipe is arranged on one side of the refrigeration unit, and the water inlet end of the spray pipe is connected with a flexible water delivery pipe.

[0027] The low-pressure refrigerant inhaled into the pipeline system by the compressor is compressed into a high-temperature and high-pressure gaseous refrigerant and enters the condenser 42. Since a heat dissipation fan for forced air convection is provided in the condenser 42, at this time, due to the action of the heat dissipation fan, the surrounding normal-temperature air will continuously enter the fin gaps on both sides of the unit through the condenser 42, thereby taking away the heat on the surfaces of the fins and copper pipes. At the same time, the refrigerant continuously liquefies in the condenser. The liquid refrigerant flows through the throttling device and enters the evaporator 41. At this time, the pressure and temperature of the refrigerant have both decreased. When the liquid refrigerant ejected from the throttling device enters the evaporator 41, it quickly absorbs heat and expands and evaporates. Since a blower for forced air convection is provided in the evaporator 41, the air in the area to be cooled will be continuously inhaled through the air inlet 23 on the side of the evaporator 41 and flow through the fin gaps of the evaporator 41 at this time, so that the heat is continuously taken away, and the cooled cold air is continuously blown into the room through the air outlet 22. The refrigeration system operates according to the above cycle, repeating continuously to achieve the purpose of regional cooling.

[0028] The cold air generated by the refrigeration unit is discharged through the blower group to cool down the mine tunnel. The refrigerated vehicle is driven by the drive system, eliminating the need for a trailer, making it move more quickly and operate more conveniently. Since the hot air outlet of the refrigeration unit has been discharging hot air into the non-refrigerated area for a long time, the temperature in the non-refrigerated area is very high. At the same time, various devices such as the compressor in the refrigeration unit also generate a large amount of heat during operation. Excessive temperature will cause various devices such as the compressor in the refrigeration unit to stop running. The refrigeration unit is cooled by the spraying device to ensure that the refrigeration unit can continue to work.

[0029] The refrigeration unit generates low-temperature coolant and transports it to the blower group. The blower group sucks the air in the refrigerated area into the blower group through the air inlet for heat exchange. The air cooled down after heat exchange is discharged into the refrigerated area through the cold air outlet of the blower group. From

[0030] By setting two sets of air duct fabrics, the connecting part at one end of the air duct fabric is installed and connected to the cold air outlet through threads. The other set of air duct fabric is also connected through the connecting part. By setting multiple joint rings, it is convenient to contract and stretch the air duct fabric according to the required length during use.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
