Description

Technical Field

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

[0002] An air compressor, abbreviated as an air compressor, is the main body in the air source device. It is a device that converts the mechanical energy of the prime mover into pressure energy and is a pneumatic generating device for compressed air. As a movable emergency air source, a medical air compressor plays a crucial role in providing a clean and pure air source for medical equipment.

[0003] The working principle of an air compressor is to compress the input low-pressure gas through a compression pump to produce high-pressure and high-temperature gas (the temperature can reach 75 - 90 degrees Celsius). Through subsequent heat dissipation systems, filtration systems, and pneumatic control systems, the high-temperature and high-pressure gas is converted into low-temperature and high-pressure dry gas, and the output is supplied to users.

[0004] Currently, in medical clinics, medical air compressors are used in a one-to-one matching manner with ventilators and anesthetic machines separately. Existing medical air compressors generally have a first-stage cooling design, and the drainage design is generally after the air storage tank.

[0005] The inventor believes that: this existing technology has the defect that the water vapor after cooling the compression pump is likely to stay in the compression pump pipeline or flow into other devices, and the condensation of water vapor causes harm and failures to the equipment, reducing the service life of the equipment. Summary of the Invention

[0006] In view of the deficiencies of the existing technology, the present invention proposes a medical air compressor system. This medical air compressor can effectively solve the problems existing in the existing technology and extend the service life of the air compressor.

[0007] A medical air compressor system provided by the present invention adopts the following technical solutions:

[0008] A medical air compressor system includes a front-end load starting system. The front-end load starting system includes an intake filter F3, a compression pump connected to the intake filter F3, a radiator HE connected to the compression pump and used for condensing high-temperature and high-pressure gas, a relief valve RV, and a drain silencer F4 used for discharging the condensed coolant. A connecting pipe 1 is provided between the radiator HE and the drain silencer F4, and the radiator HE is connected to the drain silencer F4. The relief valve RV is arranged on the connecting pipe 1. When the relief valve RV is opened, the water condensed by the radiator HE enters the drain silencer F4 through the connecting pipe 1 and is discharged through the drain silencer F4.

[0009] By adopting the above technical solution, when the compression pump works, the compression pump is communicated with the external atmospheric pressure, and the pressure inside the compression pump is released through the relief valve RV, reducing the starting load of the compression pump, realizing the pressure reduction treatment of the compression pump. At the same time, the condensed water produced after the high-temperature and high-pressure gas processed by the compression pump is cooled and condensed by the radiator HE flows through the opened relief valve RV, through the first connecting pipe into the drain silencer F4 and is discharged outwards, realizing the discharge of the front-end liquid, and can avoid the water vapor after the compression pump is cooled from staying in the compression pump pipeline or flowing into other devices, and the condensation of water vapor causes harm and failures to the equipment, thereby extending the service life of the air compressor;

[0010] At the same time, the airflow that releases the pressure inside the compression pump through the relief valve RV continuously flushes the drain filter F4, flushing the particulate matter in the airflow to the outside of the drain filter F4, preventing the particulate matter from accumulating in the drain filter F4, so as to extend the service life of the air compressor and reduce the maintenance frequency.

[0011] Optionally, it further includes a three-stage drainage control system. The three-stage drainage control system includes: a cooler communicated with the first connecting pipe, an internal water filter WT1 communicated with the cooler, and a drain solenoid valve SOL1 for discharging the condensate. A second connecting pipe is arranged between the internal water filter WT1 and the drain silencer F4, and the internal water filter WT1 is communicated with the drain silencer F4. The drain solenoid valve SOL1 is arranged on the second connecting pipe.

[0012] By adopting the above technical solution, through the setting of the three-stage drainage control system, the liquid condensate generated by the gaseous water condensation system is filtered by the internal water filter WT1, and after the condensate is collected, it is discharged to the drain silencer F4 through the drain solenoid valve SOL1, realizing the primary discharge of the water vapor in the gas, and further improving the effect of discharging the water vapor.

[0013] Optionally, the three-stage drainage control system further includes an internal air storage tank communicated with the internal water filter WT1, a water level sensor WS arranged on the internal air storage tank, and a monitoring drain solenoid valve SOL2. A third connecting pipe is arranged between the internal air storage tank and the drain silencer F4, and the internal air storage tank is connected to the drain silencer F4. The monitoring drain solenoid valve SOL2 is arranged on the third connecting pipe.

[0014] By adopting the above technical solution, the low-temperature and high-pressure gas flows into the internal air storage tank through the internal water filter WT1 for storage and precipitation. If the water level sensor WS detects liquid water in the internal air storage tank, the monitoring drain solenoid valve SOL2 is started, so that the condensate in the internal air storage tank can be discharged through the third connecting pipe through the drain silencer F4, realizing the secondary discharge of the water vapor in the gas, and further improving the effect of discharging the water vapor.

[0015] Optionally, a manual exhaust valve SV is provided on the connecting pipe three, and the manual exhaust valve SV is arranged between the internal gas storage tank and the monitoring drain solenoid valve SOL2.

[0016] By adopting the above technical solution, through the setting of the manual exhaust valve SV, when the monitoring drain solenoid valve SOL2 malfunctions, the internal gas storage tank can be drained and tested through the manual exhaust valve SV to achieve the third discharge of the water vapor in the gas, further improving the effect of discharging the water vapor. At the same time, this technical solution can be used to judge the abnormal source of the gaseous water condensation system and facilitate the maintenance of the air compressor.

[0017] Optionally, it further includes a clean gas recovery and compression system. The clean gas recovery and compression system includes a one-way valve CV1. A connecting pipe four is provided between the internal gas storage tank and the intake filter F3. The one-way valve CV1 is arranged on the connecting pipe four and is located between the intake filter F3 and the internal gas storage tank.

[0018] By adopting the above technical solution, through the setting of the clean gas recovery and compression system, when the air pressure in the internal gas storage tank is higher than the air pressure in the connecting pipe four, the gas in the internal gas storage tank will push open the one-way valve CV1, and the low-temperature and high-pressure clean gas will be blown back into the intake filter F3 and the compression pump through the connecting pipe four, realizing the reverse flushing air flow of the intake filter F3, flushing the particulate matter attached to the intake filter F3 due to the suction of the compression pump with the reverse flushing air flow, improving the service life of the intake filter F3, and at the same time enabling part of the clean gas to enter the compression pump for recycling, effectively reducing the energy consumption of the equipment.

[0019] Optionally, the clean gas recovery and compression system further includes a pressure regulating valve Reg arranged on the connecting pipe four, and the pressure regulating valve Reg is located between the intake filter F3 and the one-way valve CV1.

[0020] By adopting the above technical solution, through the setting of the pressure regulating valve Reg, when the air pressure of the gas reaching the pressure regulating valve Reg is greater than the threshold value of the pressure regulating valve Reg, the low-temperature and high-pressure clean gas will open the pressure regulating valve Reg and enter the intake filter F3. The intake filter F3 is flushed with high-pressure gas, and at the same time, after the gas is regulated by the pressure regulating valve Reg, low-temperature, high-pressure, clean and highly stable gas meeting the user's requirements is output.

[0021] Optionally, the clean gas recovery and compression system further includes an intake filter cotton F2 arranged at the intake filter F3.

[0022] By adopting the above technical solution, through the setting of the intake filter cotton F2, the gas entering the intake filter F3 can be filtered.

[0023] Optionally, the pressure regulating valve Reg is provided with three interfaces, two of which are installed on the connecting pipe four, and the other interface is connected to a conveying pipe one, and the other end of the conveying pipe one is connected to a backup gas storage tank.

[0024] By adopting the above technical solution, through the conveying pipe one, the low-temperature and high-pressure gas meeting the user requirements can enter the backup gas storage tank through the conveying pipe one for storage.

[0025] Optionally, a conveying pipe two is connected to the conveying pipe one, the other end of the conveying pipe two is connected to a central air switching component, and a three-stage water filter WT2 is connected to the central air switching component.

[0026] By adopting the above technical solution, through the conveying pipe two, the low-temperature and high-pressure gas meeting the user requirements can be transported to the user through the central air switching component and the three-stage water filter.

[0027] Optionally, a heat dissipation and noise reduction system is further included, and the heat dissipation and noise reduction system includes an intake air filter F1, a fan, and a refrigeration fan. The intake air filter F1 is arranged at the radiator HE and the refrigeration device, the fan is arranged at the compression pump, and the refrigeration fan is arranged at the refrigeration device.

[0028] By adopting the above technical solution, the intake air filter F1 is the main component of the heat dissipation intake air channel of the heat exchanger HE, the fan, and the refrigeration device, and the heat of the compression device, the heat exchanger HE, and the refrigeration device is dissipated through the combined heat dissipation channel. At the same time, the heat dissipation channels are separated according to different heat dissipation air pressures to dissipate the heat generated during the working process and effectively reduce the mutual interference of the heat dissipation airflows. The air intake, the compressed gas release, and the compression device are the main noise sources of the air compressor.

[0029] In summary, the present invention includes at least one of the following beneficial technical effects:

[0030] 1. Through the setting of the front-end load startup system, when the compression pump works, if the pressure difference between the compression pump and the external atmospheric pressure exceeds the preset value, the relief valve RV automatically opens to release the pressure in the compression pump, reduce the startup load of the compression pump, and achieve the pressure reduction treatment of the compression pump. At the same time, the condensed water produced after the high-temperature and high-pressure gas processed by the compression pump is cooled and condensed by the radiator HE flows through the opened relief valve RV, through the connecting pipe one into the drainage silencer F4 and is discharged outwards, realizing the discharge of the front-end liquid, and can avoid the water vapor after the compression pump is cooled from staying in the compression pump pipeline or flowing into other devices, and the condensation of the water vapor causes harm and faults to the equipment, thereby prolonging the service life of the air compressor;

[0031] 2. Through the setting of the three - stage drainage control system, the high - temperature and high - pressure gas is further cooled to about 10 degrees by the cooler. The generated condensate and the low - temperature and high - pressure gas flow through the built - in water filter WT1 for filtration. After collecting the condensate, it is discharged through the drainage solenoid valve SOL1 to the drainage silencer F4, realizing the secondary discharge of the water vapor in the gas and further improving the effect of discharging the water vapor.

[0032] 3. Through the setting of the one - way valve CV1, the gas in the internal gas storage tank can be output more stably, reducing the oscillation amplitude of the gas in the internal gas storage tank. Brief Description of the Drawings

[0035] The following further describes the present invention in detail with reference to the attached Figure 1 drawings.

[0036] An embodiment of the present invention discloses a medical air compressor system. Referring to Figure 1 , it includes a front - end load - starting system, a three - stage drainage control system, a clean gas recovery and compression system, and a heat dissipation and noise reduction system. A low - pressure gas is input into the front - end load - starting system, and after passing through the front - end load - starting system, the three - stage drainage control system, and the clean gas recovery and compression system in sequence, finally, the low - temperature and high - pressure gas meeting the user's requirements is delivered to the user.

[0037] Among them, referring to Figure 1 , the front - end load - starting system includes an intake filter F3, a compression pump connected to the intake filter F3, a radiator HE connected to the compression pump and used for condensing high - temperature and high - pressure gas, a relief valve RV, and a drainage silencer F4 used for discharging the condensed coolant. The intake filter F3 is connected to a compensation voltage (COV). A first connecting pipe 1 is arranged between the radiator HE and the drainage silencer F4, and the radiator HE is connected to the drainage silencer F4. The relief valve RV is arranged on the first connecting pipe 1.

[0038] Referring to Figure 1, start the compression pump. Since the port A of the compression pump is connected to the atmospheric pressure, the starting load of the compression pump is reduced. Because a negative pressure is formed inside the compression pump, the low-pressure gas in the room is sucked in and filtered through the intake filter F3. The filtered gas enters the compression pump, and the compression pump compresses the gas, and the high-temperature, high-pressure gas rich in moisture is output from the port B of the compression pump. At the same time, judge the air pressure inside the compression pump. When the pressure difference between the compression pump and the outside atmospheric pressure exceeds the preset value and the voltage is too low, the relief valve RV automatically opens to quickly release the pressure inside the compression pump, reduce the starting load of the compression pump, and enable the compression pump to work normally, completing the decompression process of the compression pump. After the compression pump starts, the high-temperature, high-pressure gas passes through the radiator HE, and the heat of the radiator HE is taken away by the negative pressure generated when the cooling fan sucks air, and the high-temperature, high-pressure, high-humidity gas is cooled and condensed for the first time, and the high-temperature, high-pressure, high-humidity gas with condensed moisture is output. The condensate gathers at the relief valve RV, and the relief valve RV opens, and the condensate is directly drained into the drain silencer F4 through the connecting pipe 1 and discharged to the outside through the drain silencer F4, discharging the liquid and completing the first system water filtration and drainage process.

[0039] Refer to Figure 1 , the three-stage drainage control system includes: a cooler connected to the connecting pipe 1, an internal water filter WT1 connected to the cooler, a drainage solenoid valve SOL1 for discharging the condensate, an internal air storage tank connected to the internal water filter WT1, a water level sensor WS provided on the internal air storage tank, and a monitoring drainage solenoid valve SOL2. A connecting pipe 2 is provided between the internal water filter WT1 and the drain silencer F4, and the internal water filter WT1 is connected to the drain silencer F4. The drainage solenoid valve SOL1 is provided on the connecting pipe 2. A connecting pipe 3 is provided between the internal air storage tank and the drain silencer F4, and the internal air storage tank is connected to the drain silencer F4. The monitoring drainage solenoid valve SOL2 is provided on the connecting pipe 3. A manual exhaust valve SV is provided on the connecting pipe 3, and the manual exhaust valve SV is provided between the internal air storage tank and the monitoring drainage solenoid valve SOL2.

[0040] Refer to Figure 1, the cooler is a thermoelectric cooler. The high-temperature, high-pressure and high-humidity gas undergoes secondary refrigeration through the cooler, reducing the temperature of the compressed gas to about 10°C. The generated condensed water and the low-temperature and high-pressure gas flow through the built-in water filter WT1 for water-gas separation, outputting low-temperature and dry high-pressure gas. The condensed liquid is collected and discharged to the drain silencer F4 through the drain solenoid valve SOL1 and the connecting pipe two 2, and finally discharged through the drain silencer F4 to complete the secondary drainage control to prevent the separated liquid water from flowing into the internal gas storage tank. The water level sensor WS is electrically connected to the monitoring drain solenoid valve SOL2. The low-temperature, high-pressure and dry gas flows into the internal gas storage tank for storage and precipitation. The water level sensor WS detects whether the incoming low-temperature and high-pressure gas carries condensed water. If it is detected that the incoming gas still has not drained all the water, the monitoring drain solenoid valve SOL2 is activated to perform secondary drainage of the condensed water in the internal gas storage tank through the connecting pipe three 3 and the drain silencer F4. When the monitoring drain solenoid valve SOL2 fails, the internal gas storage tank can be drained and tested through the manual exhaust valve SV to determine the fault source and complete temporary fault maintenance.

[0041] Refer to Figure 1 , the clean gas recovery and compression system includes a pressure sensor PS for monitoring the air pressure in the internal gas storage tank, a check valve CV1, a pressure regulating valve Reg, and an intake filter cotton F2 provided at the intake filter F3. A connecting pipe four 4 is provided between the internal gas storage tank and the intake filter F3. The pressure regulating valve Reg is provided on the connecting pipe four 4, and the check valve CV1 is provided on the connecting pipe four 4 and is located between the intake filter F3 and the internal gas storage tank; the pressure regulating valve Reg is located between the intake filter F3 and the check valve CV1. The pressure regulating valve Reg has three interfaces, two of which are installed on the connecting pipe four 4, and the other interface is connected to a delivery pipe one 5. The other end of the delivery pipe one 5 is connected to a reserve gas storage tank. A delivery pipe two 6 is connected to the delivery pipe one 5, and the other end of the delivery pipe two 6 is connected to a central air switching component. A three-stage water filter WT2 is connected to the central air switching component.

[0042] Refer to Figure 1, the pressure sensor PS is used to monitor the air pressure in the internal gas storage tank, enabling operators to detect the air pressure in the internal gas storage tank in real time. When the air pressure in the internal gas storage tank is too high, the compressor system is powered off. The check valve CV1 can reduce the oscillation amplitude of the gas in the internal gas storage tank, allowing for stable output. As a result, the low-temperature and high-pressure dry gas reaches the pressure regulating valve Reg after passing through the check valve CV1. When the difference between the air pressure inside the internal gas storage tank and the external air pressure is greater than the preset threshold, the diversion port of the pressure regulating valve Reg is opened by the gas in the connecting pipe 4. The low-temperature and high-pressure gas passes through the connecting pipe 4 and enters the pipe connected to the intake filter F3 and the compression pump port A, using the high-pressure gas to clean the intake filter F3 and the intake filter cotton F2, and recycling part of the gas to the compression pump. After the low-temperature and high-pressure dry gas is diverted by the pressure regulating valve Reg after passing through the check valve CV1, low-temperature and high-pressure gas meeting the user's requirements is output. Part of it flows into the backup gas storage tank through the conveying pipe 1 5, and part of it directly flows through the central air switching component and the three-stage water filter WT2 through the conveying pipe 2 6 and is output to the user, completing the compression operation of the air.

[0043] Refer to Figure 1 , the heat dissipation and noise reduction system includes an intake filter net F1, a fan, and a refrigeration fan. The intake filter net F1 is arranged at the radiator HE and the refrigerator. The fan is arranged at the compression pump and is used to cool the compression pump. The refrigeration fan is arranged at the refrigerator. The high-temperature, high-pressure, and high-humidity gas undergoes secondary refrigeration through the refrigerator. Meanwhile, under the action of the refrigeration fan, the dew point can reach -40°C. When the air is inhaled by the compression device, a gas vortex is formed in the intake filter F3, generating an intake noise. By utilizing the characteristics of the intake filter cotton net F2 and the intake filter F3, the gas vortex is greatly reduced, thereby achieving a reduction in the air intake noise. The relief valve RV, the drain solenoid valve SOL1, and the monitoring drain solenoid valve SOL2 release high-pressure airflows, causing disturbances in the surrounding static air and generating jet noises. The higher the pressure and the higher the release flow rate, the greater the noise. By utilizing the throttling and pressure reduction characteristics of the drain silencer F4, the noise of the compressed gas release is reduced. Additionally, the rotational noise generated during the operation of the compression device is transmitted out through the heat dissipation channel. By utilizing the combined noise reduction characteristics of the maze and chamber types of the heat dissipation channel, the operating noise of the compression device is reduced.

[0044] The above are only the embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various modifications and changes can be made to the present invention.
