Description

Technical Field

[0001] The present invention relates to the technical field of air compression, and particularly to an efficient and energy-saving magnetic levitation centrifugal air compressor. Background Art

[0002] The magnetic levitation centrifugal air compressor uses magnetic levitation technology to replace the traditional mechanical bearings, enabling the rotor to move in a non-contact and frictionless state, thereby eliminating the mechanical wear generated during the movement of the rotor in the traditional air compressor and the pollution problem caused by the lubricating oil. Currently, the disadvantages of the magnetic levitation centrifugal air compressor are as follows: its intake end is directly connected to the atmosphere, and the extremely fast flow velocity during the suction process will generate huge noise, which is a kind of pollution to the environment. Working in this environment for a long time is likely to affect the hearing of users. If a silencing device is set at the intake end, the air flow entering the magnetic levitation centrifugal air compressor will be unstable, resulting in pressure loss, thereby affecting the efficiency of the magnetic levitation centrifugal air compressor.

[0011] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0012] Such as Figure 1 、 Figure 2As shown in the figure, the present invention provides an efficient and energy-saving magnetic levitation centrifugal air compressor, which includes a chassis 1 and a magnetic levitation main unit 2 disposed within the chassis 1. One end of the magnetic levitation main unit 2 is provided with a primary compression air inlet 3 and a primary compression air outlet 4, and the other end is provided with a secondary compression air inlet 5 and a secondary compression air outlet 6. The end of the primary compression air outlet 4 is connected to the inlet of a gas cooler 7, and the outlet of the gas cooler 7 is connected to the secondary compression air inlet 5 through a secondary air pipe 8. An air inlet of the chassis 1 is provided on the chassis 1. An air inlet box 9 is disposed within the chassis 1. A serpentine sound-absorbing channel 10 and a filtering channel 11 connected to the lower end of the serpentine sound-absorbing channel 10 are provided in the air inlet box 9. The upper end of the serpentine sound-absorbing channel 10 communicates with the air inlet of the chassis 1. A plurality of filtering outlets are provided on the side wall of the filtering channel 11. Air filters 12 corresponding to the filtering outlets one by one are provided in the filtering channel 11. A conical funnel 13 is provided outside the air inlet box 9. The large end of the conical funnel 13 is connected to the air inlet box 9 and covers the plurality of filtering outlets therein. The small end of the conical funnel 13 is connected to the primary compression air inlet 3 through a primary air pipe 14. The primary air pipe 14 is a flexible pipe, which is convenient for connection.

[0013] When the present invention is in use, the magnetic levitation main unit 2 operates to suck a large amount of air from the air inlet of the chassis 1 and enter the serpentine sound-absorbing channel 10. The serpentine sound-absorbing channel 10 can effectively reduce the noise caused by the fast air flow speed during the air intake process. Then the air enters the filtering channel 11. The air is dispersed around the plurality of air filters 12, and impurities in the air can be removed when passing through the air filters 12, improving the air quality. The filtered air flows into the conical funnel 13 from the corresponding filtering outlets. The conical funnel 13 plays a role in converging the air, which can effectively prevent pressure loss. Then the air enters the magnetic levitation main unit 2 from the primary compression air inlet 3 through the primary air pipe 14. After being pressurized at the primary stage, it enters the gas cooler 7 from the primary compression air outlet 4. The gas cooler 7 cools the air with an increased temperature during the pressurization process. The cooled air enters the magnetic levitation main unit 2 again from the secondary air pipe 8 and the secondary compression air inlet 5 for secondary pressurization. The gas cooler 7 cools the air to prevent the air entering the magnetic levitation main unit 2 from being too hot. The air after secondary pressurization enters the exhaust pipe through the secondary compression air outlet 6 and is discharged.

[0014] Preferably, a cooling channel is provided around the magnetic levitation main machine 2. A cooling air inlet is provided on one side of the cooling channel. The cooling air inlet is connected to a cooling fan 16 through a cooling air inlet pipe 15. A cooling air outlet is provided on the other side of the cooling channel. The cooling air outlet is connected to a discharge port through a cooling air outlet pipe 27. A coolant tank 17 and a cooling water tank 18 are further provided in the chassis 1.

The outlet of the water tank coolant pipeline is connected to the liquid return port of the coolant tank 17 through a coolant return pipe 21. A coolant pump 22 is provided on the coolant return pipe 21. A cooling water inlet and a cooling water outlet are provided on the cooling water tank 18, and the cooling water can be replaced. The cooling fan 16 blows cold air into the cooling channel of the magnetic levitation main machine 1 through the cooling air inlet pipe 15 and the cooling air inlet. The cold air flows through the cooling channel and then is discharged from the cooling air outlet, the cooling air outlet pipe 27 and the discharge port, thereby taking away the heat dissipated by the magnetic levitation main machine 1, constituting an air cooling system, and achieving the effect of cooling the magnetic levitation main machine. The coolant in the coolant tank 17 is circulated in sequence through the main machine cooling liquid inlet pipe 19, the main machine coolant pipeline, the main machine coolant outlet pipe 20, the water tank coolant pipeline, and the coolant return pipe 21 by the coolant pump 22. The coolant in the main machine coolant pipeline cools the magnetic levitation main machine 1. When the coolant passes through the water tank coolant pipeline in the cooling water tank 18, the cooling water in the cooling water tank 18 cools the coolant, constituting a water cooling system, and achieving a better cooling effect.

[0015] Preferably, the magnetic levitation main machine 1 is electrically connected to a frequency converter 23. The frequency converter can adjust the rotational speed and power of the magnetic levitation main machine, thereby achieving the effects of energy saving, noise reduction, extending the service life of the equipment, and improving the operating efficiency. A frequency converter coolant pipeline is provided in the frequency converter 23. The inlet of the frequency converter coolant pipeline is connected to the liquid outlet of the coolant tank 17 through a frequency converter cooling liquid inlet pipe 24. The outlet of the frequency converter coolant pipeline is connected to the inlet of the water tank coolant pipeline through a frequency converter cooling liquid outlet pipe 25. While cooling the magnetic levitation main machine 1, the water cooling system can also cool the frequency converter 23.

[0016] Preferably, an air inlet hood 26 with side air intake is provided over the chassis air inlet, facilitating the entry of external air into the chassis air inlet.
