Description

Technical Field

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

[0002] An air compressor is a device used to compress gas and increase its pressure. Its main function is to draw air from the atmosphere into the machine and then compress it mechanically to increase the pressure and temperature of the air, thereby providing a power source or process gas for various industrial applications. The power of a pneumatic booster air compressor comes from compressed air. This design uses the energy of compressed air to drive the piston to reciprocate, thereby achieving air compression and pressure increase.

[0003] The existing pneumatic air compressors are divided into two categories: single-acting and double-acting. Both rely on high-pressure gas to push the piston to compress the air. The single-acting type relies on a spring or other mechanical reset piston, while the double-acting type alternately intakes air through the chambers on both sides to achieve a more efficient but higher temperature rise compressed air process. Due to the intensified collision of gas molecules and the heat generated by the high-pressure gas driving the piston, the temperature in the chamber of the compressed gas will rise significantly during the continuous air compression process, especially for the double-acting type. The high temperature will cause local overheating, which is more likely to cause lubricating oil failure and increase friction resistance, thereby causing deformation or damage to the piston, cylinder wall and other key components. Based on this, the present invention purposely provides a pneumatic booster air compressor that can ensure that the compressed air chamber is always in a low temperature environment while continuously compressing the air. Summary of the invention

[0004] The purpose of the present invention is to provide a pneumatic booster air compressor to address the deficiencies of the prior art, so as to solve the technical problem that the heat generated when compressing air accumulates in the compressed air chamber and cannot be dissipated in time, which easily causes local overheating.

[0005] The purpose of the present invention can be achieved through the following technical solutions: A pneumatic booster air compressor, comprising: An air storage tank, on which a mounting platform is fixedly mounted, on which a cavity is fixedly mounted, in which a piston is slidably mounted, and a first chamber and a second chamber are respectively opened at two ends of the gas storage tank, and the two ends of the gas storage tank are respectively opened, and the two ends of the piston are respectively located in the first chamber and the second chamber, and the first chamber and the second chamber are both connected with an inflation valve, an air intake valve, an exhaust valve and an exhaust gas recovery valve, the inflation valve is connected with a high-pressure gas source device, the exhaust gas recovery valve is connected with the gas storage tank, and the inflation valve, the air intake valve, the exhaust valve and the exhaust gas recovery valve are all connected with a controller; Cooling cylinders, two cooling cylinders are respectively arranged on the outer walls of the first chamber and the second chamber, each cooling cylinder is filled with cooling water, and each cooling cylinder is provided with a circulating cooling assembly; The control component is arranged on the cavity and is connected to the circulating cooling component and the exhaust valve. When the controller controls the exhaust valve to open, the high-pressure gas discharged from the exhaust valve drives the circulating cooling component to operate through the control component, and the cooling water in the cooling cylinder circulates at this time.

[0006] As a further solution of the present invention: the circulating cooling component includes a circulating pipe, a turbine pump and a condenser, a mounting plate is fixedly installed on the mounting platform, the input end and the output end of the circulating pipe are connected to the cooling cylinder, the turbine pump and the condenser are arranged on the circulating pipe, and both are fixedly installed on the mounting plate, and the rotating shaft of the turbine pump is driven by the control component to rotate intermittently.

[0007] As a further solution of the present invention: the input end of the circulation pipe is connected to the highest point of the cooling cylinder, and the output end of the circulation pipe is connected to the lowest point of the cooling cylinder.

[0008] As a further solution of the present invention: the control component includes a delivery pipe, an air collecting pipe, a wind wheel and a synchronous belt; a fixed plate is fixedly installed on the mounting platform; the wind wheel is rotatably installed on the fixed plate, and its rotating shaft is transmission-connected to the rotating shaft of the turbine pump through a synchronous belt; the air collecting pipe is fixedly installed on the fixed plate, and its air outlet faces the blades of the wind wheel; the air collecting pipe is connected to the exhaust valve through the delivery pipe.

[0009] As a further solution of the present invention: the number of the delivery pipes is two, the two delivery pipes are respectively connected to the two exhaust valves, and the output ends of the two delivery pipes are both connected to the air collecting pipe.

[0010] As a further solution of the present invention: a blowing pipe is fixedly installed on the mounting plate, the air outlet of the blowing pipe faces the turbine pump and the condenser, the air inlet of the blowing pipe is provided with an air collecting component, and the air collecting component cooperates with the air collecting pipe.

[0011] As a further solution of the present invention: the wind collecting assembly includes a wind collecting hood and a connecting pipe, the wind collecting hood is fixedly installed on the fixed plate, the blades of the wind wheel and the air outlet of the wind collecting pipe are both located in the wind collecting hood, and the wind collecting hood is connected to the blowing pipe through the connecting pipe.

[0012] As a further solution of the present invention: an air cooling component is arranged on the mounting platform, and the air cooling component cooperates with the cavity.

[0013] Beneficial effects of the present invention: 1. In the present invention, the cooling water filled in the cooling cylinder can absorb the heat from the outer wall of the first chamber and the second chamber by direct contact, thereby avoiding the occurrence of local overheating. When the controller controls the exhaust valve to open and discharge the high-pressure gas that has completed the task, the high-pressure gas discharged by the exhaust valve drives the circulation cooling component to operate through the control component, thereby circulating the cooling water in the cooling cylinder. In this way, it is ensured that the cooling water in the cooling cylinder can be circulated after each air compression, thereby avoiding the water temperature of the cooling water from rising to a temperature at which heat exchange with the first chamber and the second chamber cannot be performed, thereby ensuring that the cooling effect is always good. 2. In the present invention, when the cooling water in the cooling cylinder is circulated, the heated cooling water is pumped away while the cooled cooling water enters the cooling cylinder. Thus, the cooling water in the cooling cylinder will be relatively distributed in cold water and hot water. Since the density of cold water is greater than that of hot water, the cold water tends to sink below the cooling cylinder, while the hot water floats to the top of the cooling cylinder due to its smaller density. The input end of the circulation pipe is arranged above the cooling cylinder, so that the hot water can be pumped away first, and the cold water is injected into the cooling cylinder from below, so that the cold water can be gathered at the bottom, avoiding the situation where the cold water is injected from above and then sinks and is pumped away. 3. In the present invention, a large amount of high-pressure gas gushes out from the air outlet of the air collecting pipe and hits the blades of the wind wheel, thereby causing the wind wheel to rotate. The rotation of the wind wheel drives the turbine pump shaft to rotate through the synchronous belt, thereby circulating the cooling water. This process ensures that during continuous operation, the circulating cooling component can effectively remove heat from the chamber to prevent overheating, and reasonably utilizes the energy of the high-pressure gas that has completed the task and is discharged from the chamber as a power source, thereby realizing the secondary utilization of energy and improving the overall utilization rate of energy.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-Figure 6 As shown, the present invention is a pneumatic booster air compressor, comprising: A gas storage tank 1, on which a mounting platform 2 is fixedly mounted, on which a cavity 3 is fixedly mounted, in which a piston 4 is slidably mounted, and a first chamber 5 and a second chamber 6 are respectively opened at both ends of the cavity 3, and the two ends of the cavity 3 are respectively opened, and the two ends of the piston 4 are respectively located in the first chamber 5 and the second chamber 6, and the first chamber 5 and the second chamber 6 are both connected with an inflation valve 7, an air intake valve 8, an exhaust valve 9 and an exhaust gas recovery valve 10, the inflation valve 7 is connected with a high-pressure gas source device, and the exhaust gas recovery valve 10 is connected with the gas storage tank 1, and the inflation valve 7, the air intake valve 8, the exhaust valve 9 and the exhaust gas recovery valve 10 are all connected with a controller; Cooling cylinders 11, two cooling cylinders 11 are respectively arranged on the outer walls of the first chamber 5 and the second chamber 6, each cooling cylinder 11 is filled with cooling water, and each cooling cylinder 11 is provided with a circulating cooling component 12; The control component 17 is arranged on the cavity 3 and is connected to the circulating cooling component 12 and the exhaust valve 9. When the controller controls the exhaust valve 9 to open, the high-pressure gas discharged from the exhaust valve 9 drives the circulating cooling component 12 to operate through the control component 17, and the cooling water in the cooling cylinder 11 circulates at this time.

[0019] In one case of this embodiment, the controller includes a pressure sensor for monitoring the air pressure in the first chamber 5 and the second chamber 6, a signal transmission module, a PLC control system, etc. The air intake valve 8 is connected to the air filter, and the high-pressure air source equipment can be a high-pressure gas tank, the output end of another air compressor, etc. This embodiment does not make specific limitations here.

[0020] In actual application of this embodiment, the air intake valve 8 is used to introduce outside air into the chamber to prepare for the next compression cycle. The high-pressure gas source device injects high-pressure gas into the chamber through the inflation valve 7 to push the piston 4 to move, thereby compressing the gas in another chamber. When the gas is compressed to the required pressure, the exhaust gas recovery valve 10 opens to allow the compressed gas to leave the chamber and be transported to the gas storage tank 1, while the exhaust valve 9 is used to discharge the high-pressure gas that has completed its task but still has a certain amount of energy from the chamber to prepare for the next introduction of air. like Figure 3 Taking the example shown, at this time, all the charging valves 7, the intake valves 8, the exhaust valves 9 and the exhaust gas recovery valve 10 are closed, and then the cavity 3 is about to enter the first chamber 5 compression stage. First, the intake valve 8 on the first chamber 5 is opened, and the air is introduced and then closed. Then the charging valve 7 on the second chamber 6 is opened, and the high-pressure gas is injected into the second chamber 6, pushing the piston 4 to move toward the first chamber 5, thereby compressing the air in the first chamber 5, until the air in the first chamber 5 is compressed to the required pressure, the exhaust gas recovery valve 10 on the first chamber 5 is opened, and the high-pressure gas is discharged into the gas storage tank 1, and then the exhaust valve 9 on the second chamber 6 is opened to discharge the high-pressure gas that pushes the piston 4 to move, thereby entering the second chamber 6 compression stage. Whenever the first chamber 5 completes compression and exhaust, the second chamber 6 can perform a new round of intake and compression, and this cycle continues, so that the piston 4 can continuously reciprocate, thereby realizing continuous compression of the gas; During the gas compression process, the collision frequency between gas molecules increases, and the kinetic energy is improved, which is manifested as an increase in temperature. When the high-pressure gas is injected into the chamber as a kinetic energy source, it pushes the cavity 3 to move and generates heat. This causes the temperature in the first chamber 5 and the second chamber 6 to gradually rise during the continuous gas compression process. The cooling water filled in the cooling cylinder 11 can absorb the heat from the outer walls of the first chamber 5 and the second chamber 6 through direct contact to avoid local overheating. When the controller controls the exhaust valve 9 to open and discharge the high-pressure gas that has completed the task, the high-pressure gas discharged by the exhaust valve 9 drives the circulating cooling component 12 to operate through the control component 17, thereby circulating the cooling water in the cooling cylinder 11. This ensures that the cooling water in the cooling cylinder 11 can be circulated after each air compression to avoid the cooling water temperature from rising to a temperature at which it cannot exchange heat with the first chamber 5 and the second chamber 6, thereby ensuring that the cooling effect is always good.

[0021] like Figure 1-Figure 3As shown, as a preferred embodiment of the present invention, the circulating cooling component 12 includes a circulating pipe 13, a turbine pump 14 and a condenser 15, a mounting plate 16 is fixedly mounted on the mounting platform 2, the input end and the output end of the circulating pipe 13 are both connected to the cooling cylinder 11, the turbine pump 14 and the condenser 15 are arranged on the circulating pipe 13, and both are fixedly mounted on the mounting plate 16, and the rotating shaft of the turbine pump 14 is driven by the control component 17 to rotate intermittently.

[0022] In one case of this embodiment, it should be noted that the turbine pump 14 and the condenser 15 described in the present invention are both prior arts, and the present invention does not improve them. Therefore, there is no need to disclose their specific mechanical structure and circuit structure, which does not affect the integrity of the present invention.

[0023] In actual application of this embodiment, the control component 17 drives the turbine pump 14 to rotate, so that the cooling water in the cooling cylinder 11 and the circulation pipe 13 is pumped and circulated. During the circulation process, the cooling water will pass through the condenser 15 for heat exchange and cooling. In this way, the cooling water that has been heated up after absorbing heat will be cooled and then transported back to the cooling cylinder 11. In this way, the cooling water in the cooling cylinder 11 is ensured to exchange heat at the lowest temperature in each process of compressing the air, thereby ensuring that the first chamber 5 and the second chamber 6 can continuously absorb heat and cool down.

[0024] like Figure 1-Figure 3 As shown, as a preferred embodiment of the present invention, the input end of the circulation pipe 13 is connected to the highest point of the cooling cylinder 11, and the output end of the circulation pipe 13 is connected to the lowest point of the cooling cylinder 11.

[0025] In actual application of this embodiment, when the cooling water circulates in the cooling cylinder 11, the heated cooling water is pumped away while the cooling water that has just been cooled enters the cooling cylinder 11. In this way, the cooling water in the cooling cylinder 11 will relatively form a distribution of cold water and hot water. Since the density of cold water is greater than that of hot water, the cold water tends to sink below the cooling cylinder 11, while the hot water floats to the top of the cooling cylinder 11 due to its smaller density. The input end of the circulation pipe 13 is set above the cooling cylinder 11. In this way, the hot water can be pumped away first, and the cold water is injected into the cooling cylinder 11 from below. This can ensure that the cold water gathers at the bottom, avoiding the situation where the cold water is injected from above and then sinks and is pumped away.

[0026] like Figure 1-Figure 4As shown, as a preferred embodiment of the present invention, the control component 17 includes a delivery pipe 18, an air collecting pipe 19, a wind wheel 20 and a synchronous belt 21. A fixed plate 22 is fixedly installed on the mounting platform 2. The wind wheel 20 is rotatably installed on the fixed plate 22, and its rotating shaft is transmission-connected to the rotating shaft of the turbine pump 14 through the synchronous belt 21. The air collecting pipe 19 is fixedly installed on the fixed plate 22, and its air outlet faces the blades of the wind wheel 20. The air collecting pipe 19 is connected to the exhaust valve 9 through the delivery pipe 18.

[0027] In actual application of this embodiment, when the exhaust valve 9 is opened, the high-pressure gas that has completed its task will be discharged into the delivery pipe 18, and the capacity contained in the high-pressure gas makes its delivery speed faster, and in order to drive the piston 4 to move, the amount of high-pressure gas contained in the chamber is large, and a large amount of high-pressure gas will hit the blades of the wind wheel 20 after pouring out from the blowing port of the air collecting pipe 19, thereby causing the wind wheel 20 to rotate, and the rotation of the wind wheel 20 will drive the shaft of the turbine pump 14 to rotate through the synchronous belt 21, thereby circulating the cooling water. This process ensures that during continuous operation, the circulating cooling component 12 can effectively take away heat from the chamber to prevent overheating, and reasonably utilizes the energy of the high-pressure gas that has completed its task and discharged from the chamber as a power source, thereby realizing the secondary utilization of energy and improving the overall utilization rate of energy.

[0028] like Figure 1-Figure 4 As shown, as a preferred embodiment of the present invention, the number of the delivery pipes 18 is two, the two delivery pipes 18 are respectively connected to the two exhaust valves 9, and the output ends of the two delivery pipes 18 are both connected to the air collecting pipe 19.

[0029] In actual application of this embodiment, the first chamber 5 and the second chamber 6 can be connected to the air collecting pipe 19 through two delivery pipes 18. During the process of alternating compressed air in the first chamber 5 and the second chamber 6, there is always a chamber that needs to perform the exhaust valve 9 to discharge the high-pressure gas that has completed the task, thereby causing the cooling water to circulate once. In this way, the cooling water can be circulated once between the alternating compressed air to ensure that the heat generated by the compressed air is taken away.

[0030] like Figure 1-Figure 6 As shown, as a preferred embodiment of the present invention, a blowing pipe 26 is fixedly installed on the mounting plate 16, and the air outlet of the blowing pipe 26 faces the turbine pump 14 and the condenser 15. The air inlet of the blowing pipe 26 is provided with an air collecting component 23, and the air collecting component 23 cooperates with the air collecting pipe 19.

[0031] In actual application of this embodiment, the wind blown out of the wind collecting pipe 19 is collected by the wind collecting component 23, and then blown to each turbine pump 14 and condenser 15 through the air outlet of the blowing pipe 26, so that the heat generated by the turbine pump 14 and the condenser 15 during operation can be blown away, thereby achieving a cooling effect.

[0032] like Figure 1-Figure 6 As shown, as a preferred embodiment of the present invention, the wind collecting assembly 23 includes a wind collecting hood 24 and a connecting pipe 25, the wind collecting hood 24 is fixedly mounted on the fixing plate 22, the blades of the wind wheel 20 and the air outlet of the wind collecting pipe 19 are both located in the wind collecting hood 24, and the wind collecting hood 24 is connected to the blowing pipe 26 through the connecting pipe 25.

[0033] In actual application of this embodiment, the blades of the wind wheel 20 and the air outlet of the air collecting pipe 19 are both arranged in the wind collecting hood 24. This not only allows the airflow blown out of the air collecting pipe 19 to be more concentrated on the blades of the wind wheel 20 to accelerate the rotation of the wind wheel 20, but also concentrates the airflow in the wind collecting hood 24 and transports it to the blowing pipe 26 through the connecting pipe 25. This further utilizes the energy of the high-pressure gas that has completed the task and further saves costs.

[0034] like Figure 1 As shown, as a preferred embodiment of the present invention, an air cooling component 27 is provided on the mounting platform 2 , and the air cooling component 27 cooperates with the cavity 3 .

[0035] In one case of this embodiment, it should be noted that the air cooling assembly 27 of the present invention includes an air cooler, a radiator, an air duct, a temperature control module, etc. The above components are all prior art, and the present invention does not improve them. Therefore, it is not necessary to disclose their specific mechanical structure and circuit structure, and it does not affect the integrity of the present invention. In actual application of this embodiment, the air cooling component 27 can be used to perform basic air cooling on the entire device, so that the entire device is in a relatively low temperature working environment. Combined with the cooling of the first chamber 5 and the second chamber 6 by cooling water, and the circulation of cooling water by the circulating cooling component 12, the overheating prevention capability of the entire device can be improved.

[0036] Working principle of the present invention: The above embodiment of the present invention provides a pneumatic booster air compressor, first, the suction valve 8 on the first chamber 5 is opened, the air is introduced and then closed, then the inflation valve 7 on the second chamber 6 is opened, and the high-pressure gas is injected into the second chamber 6, pushing the piston 4 to move toward the first chamber 5, thereby compressing the air in the first chamber 5, until the air in the first chamber 5 is compressed to the required pressure, the exhaust gas recovery valve 10 on the first chamber 5 is opened, and the high-pressure gas is discharged into the gas storage tank 1, and then the exhaust valve 9 on the second chamber 6 is opened to discharge the high-pressure gas that pushes the piston 4 to move, thereby entering the compression stage of the second chamber 6, every time the first chamber 5 completes compression and exhaust , the second chamber 6 can start a new round of air intake and compression, and the cycle continues. The cooling water filled in the cooling cylinder 11 can absorb the heat from the outer walls of the first chamber 5 and the second chamber 6 by direct contact, avoiding the occurrence of local overheating. When the controller controls the exhaust valve 9 to open and discharge the high-pressure gas that has completed the task, the high-pressure gas discharged by the exhaust valve 9 drives the circulating cooling component 12 to operate through the control component 17, thereby circulating the cooling water in the cooling cylinder 11. This ensures that the cooling water in the cooling cylinder 11 can be circulated after each air compression, avoiding the cooling water temperature from rising to a temperature at which it cannot exchange heat with the first chamber 5 and the second chamber 6.

[0037] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
