Description

Technical Field

[0001] This utility model belongs to the field of snowmaking air compressor technology, and particularly relates to a dual-cooling vane air compressor for snowmaking. Background Technology

[0002] Vane air compressors are widely used in the field of artificial snowmaking due to their compact structure, stable operation, and relatively low noise.

[0003] Currently available vane air compressors have the following problems in actual use: When traditional vane air compressors are used for long periods of time under high load, the cooling effect of a single cooler on the compressed air is limited, resulting in high exhaust temperature. High-temperature air is not conducive to snowmaking efficiency and may accelerate the wear and tear of subsequent pipelines and snowmaking nozzles. In order to reduce the exhaust temperature, some solutions use an additional independent air-cooled or water-cooled air cooler at the exhaust end. However, this significantly increases the size, weight and complexity of the entire unit, which is not conducive to the transportation, installation and flexible deployment of the equipment at the snowmaking site. At the same time, independent air coolers usually require additional power sources such as fan drive motors or water pumps, which increases the energy consumption, manufacturing costs and maintenance points of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a dual-cooling vane air compressor for snowmaking, in order to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A dual-cooling vane air compressor for snowmaking includes a main housing, a central oil cooler installed at one end of the main housing, a motor cooling fan connected to the side of the central oil cooler, a drive motor installed on the side of the motor cooling fan, a rear air cooler at one end of the drive motor, an oil-gas separator connected to the side of the central oil cooler, an air inlet connected to the oil-gas separator via a pipe, the air inlet being located on the surface of the rear air cooler, an exhaust port being opened on the surface of the rear air cooler, and the airflow in the rear air cooler moving along the cooling airflow path.

[0006] Preferably, a support frame is installed at the bottom of the main unit housing, a side frame is connected to the side of the support frame, and a base plate is welded to the side of the side frame.

[0007] Preferably, bolts are installed on the side of the support frame, the bolts penetrate the side frame, nuts are sleeved on the surface of the bolts, and one end of the nut is attached to the side of the side frame.

[0008] Preferably, a hanging ring is welded to the top of the oil-gas separator, and the hanging ring is located outside the main housing.

[0009] Preferably, the bolts and nuts are symmetrically distributed.

[0010] Preferably, the main housing is located at one end of the drive motor, and the motor cooling fan is located outside the rear air cooler.

[0011] This utility model discloses a dual-cooling vane air compressor for snowmaking, which has the following advantages: The dual-cooling vane air compressor for snowmaking features a central oil cooler installed at one end of the main unit housing. A motor cooling fan is connected to the side of the central oil cooler, and a drive motor is installed on the side of the motor cooling fan. A rear air cooler is located at one end of the drive motor. An oil-gas separator is connected to the side of the central oil cooler, and this oil-gas separator is connected to an air inlet via a pipe. This air inlet is located on the surface of the rear air cooler, which also has an exhaust port. The airflow in the rear air cooler moves along the cooling airflow path. When using this device, the central oil cooler is located in the middle of the unit, and its main function is to cool the high-temperature lubricating oil from the main unit's working chamber that has absorbed the heat of compression, ensuring the viscosity, lubrication performance, and sealing performance of the lubricating oil. The rear air cooler is located downstream of the main unit, near the final exhaust port. The air cooler is located at the rear of the unit. Compared to the drive motor and main unit, its main function is to provide secondary cooling for the compressed air after it has been separated by the intermediate oil cooler. At this time, the compressed air undergoes more thorough heat exchange through a two-stage cooling method. In particular, the rear-mounted air cooler deeply cools the compressed air after the initial cooling and separation by the intermediate oil cooler, making the final exhaust temperature significantly lower than that of traditional vane machines that only use oil coolers. This is more conducive to the formation of snow ice crystals, improving snowmaking efficiency and snow quality. At the same time, it eliminates the need for additional fan and motor space required for a separate air cooler. The two coolers are integrated into the core path inside the unit, with a reasonable and compact layout. Air cooling is achieved by the motor fan, eliminating the need to design separate air ducts or installation locations for the air cooler. This makes it easier to deploy and transport in snowmaking sites with limited space. It also reduces manufacturing costs and operating energy consumption, improving the system's economy and reliability. Attached Figure Description

[0022] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a dual-cooling vane air compressor for snowmaking.

[0023] like Figure 1-3 As shown, this utility model discloses a dual-cooling vane air compressor for snowmaking, comprising a main housing 1, a central oil cooler 5 installed at one end of the main housing 1, and a motor cooling fan 3 connected to the side of the central oil cooler 5. The central oil cooler 5, located in the middle of the unit, primarily cools the high-temperature lubricating oil from the main working chamber that has absorbed compression heat, ensuring the viscosity, lubrication performance, and sealing performance of the lubricating oil. A drive motor 2 is installed on the side of the motor cooling fan 3, and a rear air cooler 6 is provided at one end of the drive motor 2. The central oil cooler 5 is connected to the side of the motor cooling fan 3. The oil-gas separator 4 is connected to the air inlet 7 via a pipe. The air inlet 7 is located on the surface of the rear air cooler 6. The exhaust port 8 is opened on the surface of the rear air cooler 6. The airflow in the rear air cooler 6 moves along the cooling airflow path 9. By installing the rear air cooler 6, which is located downstream of the main unit and close to the final exhaust port 8, the main air cooler 6 is located at the rear of the unit. Relative to the drive motor 2 and the main unit, its main function is to perform secondary cooling on the compressed air separated by the intermediate oil cooler 5. Through secondary cooling, a cooling effect can be quickly achieved.

[0024] A support frame 12 is installed at the bottom of the main housing 1. A side frame 14 is connected to the side of the support frame 12. A base plate 11 is welded to the side of the side frame 14. By installing the base plate 11, the contact area between the bottom of the device and the installation position is increased, thereby improving the stability of the device after installation.

[0025] Bolts 13 are installed on the side of the support frame 12, and bolts 13 penetrate the side frame 14. Nuts 15 are fitted onto the surface of bolts 13, and one end of the nut 15 is attached to the side of the side frame 14. By installing bolts 13 and nuts 15, when installing and connecting the side frame 14 and the support frame 12, bolts 13 can penetrate the support frame 12 and the side frame 14, and then nuts 15 can be installed on bolts 13 until the nuts 15 are attached to the side of the side frame 14. At this time, the installation connection between the support frame 12 and the side frame 14 can be provided, which is very convenient to use.

[0026] The top of the oil-gas separator 4 is welded with a hanging ring 10. The hanging ring 10 is located outside the main housing 1. By installing the hanging ring 10, when moving the device, the hanging ring 10 can be used as the force point, and a hoisting device can be connected to the hanging ring 10. It is very convenient to use.

[0027] The bolts 13 and nuts 15 are symmetrically distributed. The distribution of the bolts 13 and nuts 15 can further improve the stability of the installation between the side frame 14 and the support frame 12, resulting in strong stability during use.

[0028] The main housing 1 is located at one end of the drive motor 2, and the motor cooling fan 3 is located outside the rear air cooler 6. By installing the motor cooling fan 3, the drive motor 2 can drive the cooling fan to rotate, generating forced cooling airflow, thereby further improving the cooling effect of the airflow and increasing the speed of the airflow, thus improving efficiency during use.

[0029] The working principle of this dual-cooling vane air compressor for snowmaking is as follows: When using this air compressor, a central oil cooler 5 is installed at one end of the main unit housing 1, and a motor cooling fan 3 is connected to the side of the central oil cooler 5. A drive motor 2 is installed on the side of the motor cooling fan 3, and a rear air cooler 6 is provided at one end of the drive motor 2. An oil-gas separator 4 is connected to the side of the central oil cooler 5, and the oil-gas separator 4 is connected to an air inlet 7 through a pipe. The air inlet 7 is located on the surface of the rear air cooler 6, and an exhaust port 8 is opened on the surface of the rear air cooler 6. The airflow in the rear air cooler 6 moves along the cooling airflow path 9. When using this device, the central oil cooler 5 is located in the middle of the unit, and its main function is to cool the high-temperature lubricating oil from the working chamber of the main unit that has absorbed the heat of compression, ensuring the viscosity, lubrication performance, and sealing performance of the lubricating oil. The rear air cooler 6 is located downstream of the main unit, near the final exhaust port 8. The air cooler 6 is located at the rear of the unit. Compared to the drive motor 2 and the main unit, its main function is to provide secondary cooling for the compressed air after it has been separated by the intermediate oil cooler 5. At this time, the compressed air undergoes more thorough heat exchange through a two-stage cooling method. In particular, the rear-mounted air cooler 6 deeply cools the compressed air after it has undergone preliminary cooling and separation by the intermediate oil cooler 5, so that the final exhaust temperature is significantly lower than that of a traditional vane machine that only uses an oil cooler. This is more conducive to the formation of snow ice crystals, improving snowmaking efficiency and snow quality. At the same time, it eliminates the need for additional fan and motor space required for a separate air cooler. The two coolers are integrated into the core path inside the unit, with a reasonable and compact layout. Air cooling is achieved by the motor fan, eliminating the need to design separate air ducts or installation locations for the air coolers. This makes it easier to deploy and transport in snowmaking sites with limited space. It also reduces manufacturing costs and operating energy consumption, improving the economy and reliability of the system.

[0030] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are protected by this utility model.
