[0033] Please refer to Figure 1 、 Figure 2 and Figure 3 ,in Figure 1 The utility model is a three-dimensional dual-system air compression station with multiple cooling functions. Figure 1 , Figure 2 The utility model is a three-dimensional dual-system air compression station with multiple cooling functions.

[0035] The terms "first" and "second" in the present invention are used for descriptive purposes only and should not be understood as indicating or implying relative importance, nor as limiting the order of precedence.

[0036] The utility model provides a dual-system air compressor station with multiple cooling functions, including an air intake device 12, a first cooling device 13 connected to the air intake device 12, a second cooling device 15 connected to the first cooling device 13, and a water supply device 14 connected to the first cooling device 13 and the second cooling device 15 respectively, and a post-processing device 16 connected to the second cooling device 15, the water supply device 14 transports cooling water to the first cooling device 13 and the second cooling device 15, the air and oil generated by the air intake device 12 are transported to the first cooling device 13 for cooling, the air cooled by the first cooling device 13 enters the second cooling device 15 for cooling, and the air after secondary cooling enters the post-processing device 16, the air intake device 12 is used to inhale air and transport the air and oil together to the first cooling device 13, the first cooling device 13 cools the compressed air and oil for the first time, the water supply device 14 provides water to the first cooling device 13 and the second cooling device 15, and the water cools the compressed air and oil after entering the first cooling device 13, so that the second The temperature of the compressed air in the first cooling device 13 is reduced to about 40°. The compressed air after being cooled by the first cooling device 13 enters the second cooling device 15 under the promotion of the continuous compressed air of the air inlet device 12. The second cooling device 15 reduces the temperature of the compressed air to about 35°. After being cooled by the second cooling device 15, the compressed air will produce moisture in the cooling process. When cooled in the second cooling device 15, part of the moisture in the compressed air can be taken away, thereby reducing the moisture in the compressed air. The compressed air in the second cooling device 15 enters the post-processing device 16. The post-processing device 16 adsorbs the moisture in the compressed air, which can greatly reduce the moisture in the compressed air. Since the compressed air is cooled twice by the second cooling device 15 and part of the moisture in the compressed air is taken away, the post-processing device 16 can effectively accelerate and adsorb the moisture in the compressed air. On the one hand, it can effectively improve the efficiency of the compressed air, and on the other hand, it can obtain higher quality compressed air.

[0037] Please refer to Figure 2 、 Figure 4 and Figure 6The air intake device 12 includes a motor 121, an air compressor head 122 connected to the motor 121, and an oil-gas separation cylinder 123 located on one side of the air compressor head 122 and connected to the air compressor head 122. The first cooling device 13 includes a first cooler 132 connected to the oil-gas separation cylinder 123 and used to cool the separated oil, and a second cooler 133 located above the first cooler 132 and used to cool the air. The motor 121 is used to drive the air compressor head 122 to compress air. The compressed air is continuously pushed forward by the air compressor head 122 and enters the oil-gas separation cylinder 123, and the air and the oil in the oil-gas separation cylinder 123 are transported to the first cooling device 13. Since the air is located above the oil-gas separation cylinder 123, the air enters the second cooler 133 from above the oil-gas separation cylinder 123, and the oil enters the first cooler 132 from below the oil-gas separation cylinder 123, so that the first cooler 132 can cool the separated oil, and the second cooler 133 can cool the compressed air.

[0038] The second cooler 133 includes a water circuit and an air circuit. The water circuit of the second cooler 133 is connected with the water circuit of the first cooler 132. The air circuit of the second cooler 133 is connected with the air circuit of the oil-gas separation cylinder 123. The water supply device 14 is connected with the water circuit of the second cooler 133. The oil-gas separation cylinder 123 conveys the compressed air to the second cooler 133 through the air circuit. The water supply device 14 conveys cooling water to the second cooler 133 through the water circuit to cool the compressed air. After cooling the compressed air, the cooling water enters the first cooler 132 to cool the oil in the first cooler 132. While cooling the compressed air and oil, it can also reduce the pipeline connection of the dual-system air compressor station.

[0039] The water supply device 14 includes a first water inlet pipe 141 and a first water outlet pipe 142. The first water inlet pipe 141 is connected to the water path of the second cooler 133. The first water outlet pipe 142 is respectively connected to the water path of the second cooler 133 and the second cooling device 15. The water flow of the first cooling device 13 flows from the first water inlet pipe 141 through the second cooler 133 and the first cooler 132 to the first water outlet pipe 142. The water supply device 14 provides cooling water to the second cooler 133 through the first water inlet pipe 141. The cooling water is discharged from the first water outlet pipe after passing through the second cooler 133 and the first cooler 132.

[0040] The water supply device 14 includes a second water inlet pipe 1311 and a second water outlet pipe 1313 respectively connected to the water inlet end and the water outlet end of the second cooling device 15. The water flow of the second cooling device 15 flows from the second water inlet pipe 1311 through the second cooling device 15 to the second water outlet pipe 1313. The second water inlet pipe is located below the second water outlet pipe 1313. The second water inlet pipe 1311 is used to provide cooling water to the second cooling device 15. The cooling water is discharged from the second water outlet pipe 1313 after cooling the second cooling device 15. At the same time, due to the difference in water level, the water entering from the second water inlet pipe 1311 can naturally flow to the bottom of the second cooling device 15, which is convenient for cooling the compressed air of the second cooling device 15.

[0041] Please refer to Figure 4 and Figure 5 The first cooling device 13 is also provided with a heat exchanger 131 connected to the first cooler 132. The heat exchanger 131 is connected to the first cooler 132. The oil cooled in the first cooler 132 enters the heat exchanger 131. The heat exchanger 131 cools the cooled oil again to further reduce the temperature of the hot oil.

[0042] The heat exchanger 131 is also provided with a third water inlet pipe and a third water outlet pipe respectively connected to the heat exchanger 131. The third water inlet pipe is used to transport water into the heat exchanger 131 to cool the oil in the heat exchanger 131. The cooled water in the heat exchanger 131 is discharged from the third water outlet pipe, thereby forming a cycle, which can continuously cool the oil in the heat exchanger 131.

[0043] In the present invention, the first water inlet pipe 141 , the first water outlet pipe 142 , the second water inlet pipe 1311 , the second water outlet pipe 1313 , the third water inlet pipe, and the fourth water inlet pipe are all connected to the external water tank.

[0044] The heat exchanger 131 is also provided with an oil inlet pipe 1312 connected to the oil-gas separation cylinder 123 for transporting cooled oil. The oil inlet pipe 1312 is used to transfer the oil in the heat exchanger 131 to the oil-gas separation cylinder 123, so that the oil in the oil-gas separation cylinder 123 enters the first cooler 132 for cooling, and after the oil is cooled again by the heat exchanger 131, it enters the oil-gas separation cylinder 123 to form a cycle, thereby effectively reducing the damage of the oil.

[0045] In this embodiment, an oil filter 1314 is also provided on the peripheral side of the oil-gas separation cylinder 123. The oil after heat treatment from the heat exchanger 131 is transported to the oil filter 1314, and then enters the oil-gas separation cylinder 123 through the oil filter 1314 to filter impurities in the oil.

[0046] There are two groups of air inlet devices 12 and first cooling devices 13. The two groups of first cooling devices 13 are separately connected to the two groups of air inlet devices 12. The two groups of air inlet devices 12 can speed up the efficiency of compressed air. At the same time, the two groups of air inlet devices 12 have separate first cooling devices 13 to perform the first cooling of the oil and compressed air, effectively reducing the temperature of the compressed air and the temperature of the oil.

[0047] In this embodiment, the two groups of first cooling devices 13 are connected to the second cooling device 15. On the one hand, it is used to reduce the volume of the dual-system air compression station. On the other hand, the air in the two groups of first cooling devices 13 enters the second cooling device 15, and the second cooling device 15 simultaneously cools the air transmitted from the first cooling device 13, which can effectively improve the efficiency of cooling the compressed air.

[0048] The dual-system air compressor station is also provided with a shell 11, and the air intake device 12, the first cooling device 13, the second cooling device 1515, the water supply device 14, and the post-processing device 16 are all located in the shell 11. The shell 11 is used to protect the air intake device 12, the first cooling device 13, the second cooling device 15, and the post-processing device 16. The dual-system air compressor station can be placed outdoors to prevent it from being wetted by rain or entering by debris.

[0049] Working principle:

[0050] When the air is compressed, first, the first water inlet pipe 141 of the water supply device 14 provides cooling water to the second cooler 133 and the second device through the second water inlet pipe 1311, and the third water inlet pipe provides water to the heat exchanger 131. The motor 121 is started, and the motor 121 drives the air compressor head 122 to compress the air and transmit it to the oil-gas separation cylinder 123. The air in the oil-gas separation cylinder 123 enters the second cooler 133 from the top of the oil-gas separation cylinder 123, and the oil enters the first cooler 133 from the bottom of the oil-gas separation cylinder 123. In the first cooler 132, the water in the second cooler 133 flows into the first cooler 132 after dissipating heat to the air. After dissipating heat to the oil in the first cooler 132, the water flows out from the first water outlet pipe 142. The oil cooled by the first cooler 132 enters the heat exchanger 131. The heat exchanger 131 dissipates heat to the oil again and enters the oil-gas separation cylinder 123 through the oil inlet pipe 1312, thus forming a cycle to reduce waste of resources. The water in the heat exchanger 131 flows out from the second water outlet pipe 1313 after dissipating heat to the oil.

[0051] Furthermore, the temperature of the compressed air is reduced to about 40° through water cooling in the second cooler 133. The compressed air produces a large amount of moisture during cooling, thereby reducing the moisture content in the compressed air. The compressed air cooled by the second cooler 133 enters the second cooling device 15. The second cooling device 15 reduces the temperature of the compressed air to about 35° through water cooling. The compressed air produces moisture after secondary cooling, preventing the moisture in the compressed air from entering the post-processing device 16. After cooling by the second cooling device 15, the compressed air that has discharged a large amount of moisture enters the post-processing device 16. The post-processing device 16 adsorbs the moisture in the compressed air to obtain compressed air of better quality. The compressed air after twice cooling greatly reduces the moisture content in the compressed air. The post-processing device 16 further adsorbs the moisture in the compressed air to obtain compressed air of higher quality.

[0052] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined by the claims.
