Description

Technical Field

[0001] The present invention relates to the technical field of compressors, and in particular to compressors. Background Art

[0002] A drive-type compressor is a type of positive displacement compressor that relies on the reciprocating motion of a drive element within the cylinder to compress the gas within, thereby increasing the gas pressure. A drive-type compressor system consists of a driver, crankcase, crankshaft, connecting rod, crosshead, drive rod, cylinder, drive element and piston ring assembly, packing, valve, cooler, and oil-water separator.

[0046] like Figures 1-9 As shown, in this embodiment, the compressor includes a cylinder body 1, a buffer tank assembly and a driving member 4. The cylinder body 1 has a cooling cavity 11, and the cylinder body 1 is provided with a first air inlet hole 12, a first air inlet channel 13 and a first cooling channel 14. The first air inlet hole 12 is connected to the first air inlet channel 13, and the first air inlet channel 13 is connected to the cooling cavity 11 through the first cooling channel 14. The buffer tank assembly includes a first air intake buffer tank 21 and a first exhaust buffer tank 22 integrated inside the cylinder body 1. The first air intake hole 12 is connected to the first air intake channel 13 through the first air intake buffer tank 21, and the cooling cavity 11 is connected to the first exhaust buffer tank 22. The driving member 4 is slidably provided in the cylinder body 1 and can open or close the first cooling channel 14 and the first exhaust buffer tank 22.

[0047] A first air inlet hole 12 is provided at the bottom of the cylinder body 1. The interior of the cylinder body 1 is integrated with a first air inlet channel 13, a first cooling channel 14, and a buffer tank assembly, which reduces the overall volume of the compressor and is suitable for micro compressors. No joints are required between the pipes, reducing the risk of compressor leakage. The first air inlet hole 12 is connected to the first air inlet buffer tank 21, which is connected to the first air inlet channel 13. The first air inlet channel 13 is connected to the cooling chamber 11 through the first cooling channel 14. The driving member is configured as a piston and is driven by a motor. The driving member 4 performs linear reciprocating motion along its axis. When the driving member 4 moves outward, the first cooling channel 14 and the first exhaust buffer tank 22 are opened. When the driving member 4 moves inward, the first cooling channel 14 and the first exhaust buffer tank 22 are closed. The gaseous medium enters the compressor through the air inlet, flows sequentially through the first air inlet hole 12, the first air inlet buffer tank 21, the first air inlet channel 13, the first cooling channel 14, and reaches the cooling chamber 11. The gaseous medium in the cooling chamber 11 then enters the first exhaust buffer tank 22 and is finally discharged through the compressor's exhaust port, completing the compressor's workflow. The compressor's gas piping system, buffer tank assembly, and cylinder body 1 are integrated, significantly reducing the compressor's size and ensuring smooth and stable operation.

[0048] Continue to refer to Figures 1-9The compressor also includes a drive source, an eccentric slip ring 3, and a combination valve 5. The eccentric slip ring 3 is disposed in the cylinder body 1 and connected to the output end of the drive source. One end of a driver 4 is disposed in an annular groove of the eccentric slip ring 3. The other end of the driver 4 slides through the cylinder body 1 and is connected to the combination valve 5. The combination valve 5 is disposed at the opening of the first exhaust buffer tank 22. Under the eccentric rotation of the eccentric slip ring 3, the driver 4 can extend and retract relative to the cylinder body 1 to open or close the first cooling channel 14 and the first exhaust buffer tank 22. The drive source is configured as a motor. The output end of the drive source is connected to the eccentric slip ring 3. The cylinder body 1 is mounted in the center hole of the eccentric slip ring 3. The eccentric slip ring 3 has an annular groove. One end of the driver 4 is movably positioned in the annular groove. The other end of the driver 4 penetrates the cylinder body 1 and is connected to the combination valve 5. The combination valve 5 is disposed between the cooling chamber 11 and the first exhaust buffer tank 22. The combination valve 5 serves to open and close the cooling chamber 11 to the first exhaust buffer valve 22. Under the driving action of the driving source, the eccentric slip ring 3 can rotate eccentrically relative to the cylinder body 1, thereby driving the driving member 4 to perform linear reciprocating motion along its axis. When the driving member 4 moves outward, the outer peripheral surface of one end of the driving member 4 contacts the inner track wall of the annular groove of the eccentric slip ring 3, and the inner track wall pulls the driving member 4 to complete the suction. When the driving member 4 moves inward, the outer peripheral surface of one end of the driving member 4 contacts the outer track wall of the annular groove of the eccentric slip ring 3, and the outer track wall drives the driving member 4 to perform work. Finally, the gas medium is discharged through the exhaust port, completing a working cycle. The compressor is driven by the eccentric slip ring 3 and the driving member 4. Compared with the traditional crank-connecting rod drive, the drive mechanism of this embodiment has a simple structure and stable transmission.

[0049] Reference Figure 1-Figure 5 The compressor also includes a bearing 6, which is rotatably mounted on one end of the driver 4. Driven by the driver 4, the bearing 6 can selectively contact one of the two side walls of the annular groove. A mounting hole is provided at one end of the driver 4. The bearing 6 is inserted into the mounting hole and connected via a flange nut, allowing the bearing 6 to be rotatably mounted on the driver 4. The drive source drives the eccentric slip ring 3 to rotate, thereby driving the driver 4 to perform linear reciprocating motion. When the driver 4 moves outward, the outer circumference of the bearing 6 contacts the inner track wall of the annular groove of the eccentric slip ring 3, increasing the internal volume of the cylinder 1 and creating negative pressure. The gaseous medium is drawn into the gas pipeline system integrated within the cylinder 1 through the air inlet, where the inner track wall pulls the driver 4 to complete the intake. When the driver 4 moves inward, the outer circumference of the bearing 6 contacts the outer track wall of the annular groove of the eccentric slip ring 3, reducing the internal volume of the cylinder, increasing the gas pressure, and closing the air inlet. The gaseous medium is finally discharged through the exhaust port. The driver 4 closes the exhaust port after reaching the top dead center, completing one working cycle of the compressor.

[0050] Reference Figure 1The compressor also includes a first lubricating layer and a second lubricating layer. The first lubricating layer is provided on the outer circumference of the bearing 6, and the second lubricating layer is provided on the sidewalls of the annular groove. The bearing 6 is a sealed grease bearing 6 with a first lubricating layer on its outer circumference. The inner walls of the annular groove of the eccentric ring 3 are provided with a second lubricating coating. This ensures smooth and smooth movement between the bearing 6 on the drive element 4 and the eccentric ring 3 without any jamming.

[0051] Reference Figure 1 and Figure 9 The compressor also includes a piston ring assembly 7, which is fixedly mounted on the driver 4. The cylinder body 1 is provided with a sliding channel, and the driver 4 is slidably inserted into the sliding channel so that the piston ring assembly 7 slides with the inner circumferential wall of the sliding channel. The piston ring assembly 7 includes a throttle ring 72, a support ring 71 and a piston ring 73. Along the axial direction of the driver 4, the driver 4 is sequentially provided with a throttle ring 72, a piston ring 73 and a support ring 71. Among them, the throttle ring 72 can assist the driver 4 in maintaining linear motion, reduce lateral vibration, and can preliminarily block the leakage of high-pressure gas to form a throttling effect. The piston ring 73 is adjacent to the throttle ring 72. One or more piston rings 73 can be provided. Multiple piston rings 73 are arranged at intervals along the axial direction of the driver 4. Through the effect of elastic close contact, it is ensured that the driver 4 has good sealing between the driver 4 and the cylinder body 1 during the inward or outward movement of the driver 4, thereby reducing the risk of gas leakage and ensuring compression efficiency. The support ring 71 can withstand the lateral force of the driving member 4, maintain the coaxiality of the driving member 4 and the cylinder body 1, and prevent the driving member 4 from eccentric wear.

[0052] Reference Figures 1-8 The compressor also includes a heat exchanger 8, which is mounted on the cylinder body 1 and has a first exhaust port connected to the first exhaust buffer tank 22. A first switching valve 91 is integrated with the heat exchanger 8 and is used to open or close the first exhaust port. The heat exchanger 8 is integrated with the cylinder body 1 to cool the gaseous medium within the cylinder body 1 through heat exchange and discharge it through the first exhaust buffer tank 22 and the first exhaust port. The first switching valve 91 can control the opening and closing of the first exhaust port, thereby controlling the intake and exhaust of the compressor according to demand.

[0053] Continue to refer to Figures 1-8The cylinder block 1 also defines a second air intake port 15, a second air intake passage 16, and a second cooling passage 17. The second air intake port 15 is connected to the second air intake passage 16, which in turn is connected to the cooling chamber 11 via the second cooling passage 17. The buffer tank assembly also includes a second air intake buffer tank 23 and a second exhaust buffer tank 24, which are integrated within the cylinder block 1. The second air intake port 15 is connected to the second air intake passage 16 via the second air intake buffer tank 23, and the cooling chamber 11 is connected to the second exhaust buffer tank 24. The heat exchanger 8 also defines a second exhaust port, which is connected to the second exhaust buffer tank 24. The compressor also includes a second switching valve 92, which is integrated with the heat exchanger 8 and is used to open or close the second exhaust port. When the first switching valve 91 opens the first exhaust port and the second switching valve 92 closes the second exhaust port, only the first air intake port 12, the first air intake passage 13, the first cooling passage 14, and the first air intake buffer tank 21 and the first exhaust buffer tank 22 are in operation. When the first switching valve 91 and the second switching valve 92 open the first exhaust port and the second exhaust port, respectively, the first and second gas pipeline systems integrated within the cylinder body 1 operate simultaneously. Optionally, the cylinder body 1 is provided with multiple air inlets, air inlet passages, cooling passages, and buffer tanks, and multiple switching valves are provided correspondingly to control the operation of different gas pipeline systems as required.

[0054] Continue to refer to Figures 1-8 There are multiple driving members 4, and multiple driving members 4 are arranged at intervals along the circumferential direction of the eccentric slip ring 3. In this embodiment, there are four driving members 4. Under the driving action of the driving source, the eccentric slip ring 3 can rotate eccentrically relative to the cylinder body 1, thereby driving the multiple driving members 4 to perform a cross reciprocating motion. Among them, when the driving member 4 moves outward, the outer peripheral surface of the bearing 6 contacts the inner track wall of the annular groove of the eccentric slip ring 3, and the inner track wall pulls the driving member 4 to complete the suction. When the driving member 4 moves inward, the outer peripheral surface of the bearing 6 contacts the outer track wall of the annular groove of the eccentric slip ring 3, and the outer track wall drives the driving member 4 to perform work.
