Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air compressors, in particular to a pneumatic supercharged air compressor. BACKGROUND

[0002] An air compressor is a device used to compress and increase the pressure of a gas. Its main function is to suck in atmospheric air into the machine, then compress it through mechanical means to increase its pressure and temperature, thereby providing a power source or process gas for various industrial applications. The power source of a pneumatic supercharged 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] Existing pneumatic air compressors are divided into single-acting and double-acting types, both of which rely on high-pressure gas to drive the piston to compress air. Single-acting type relies on spring and other mechanical means to reset the piston, while double-acting type realizes more efficient but higher temperature rise of compressed air process by alternating intake of two chambers. Due to the intensified collision of gas molecules and the heat generated by high-pressure gas driving the piston, the temperature inside the compressed gas chamber will rise significantly during the continuous air compression process, especially for double-acting type. High temperature may cause local overheating, which is more likely to cause lubricating oil failure, increase friction resistance, and further cause deformation or damage of piston, cylinder wall and other key components. Based on this, the present application provides a pneumatic supercharged air compressor that can ensure that the compressed air chamber is always in a low-temperature environment during continuous air compression. SUMMARY

[0004] The present application aims to solve the technical problem of heat accumulation in the compressed air chamber during air compression, which cannot be dissipated in time and is prone to local overheating.

[0007] A gas storage tank is fixedly installed on the installation table, and a cavity is fixedly installed on the installation table. A piston is slidably installed in the cavity, and first and second chambers are formed at both ends of the piston. The first and second chambers are both connected to a charging valve, a suction valve, an exhaust valve, and a waste gas recovery valve. The charging valve is connected to a high-pressure gas source device, and the waste gas recovery valve is connected to the gas storage tank. The charging valve, the suction valve, the exhaust valve, and the waste gas recovery valve are all connected to a controller.

[0008] Cooling cylinders are arranged on the outer walls of the first chamber and the second chamber respectively, each of the cooling cylinders is filled with cooling water, and each of the cooling cylinders is provided with a circulating cooling assembly;

[0009] A control assembly is arranged on the cavity and connected with the circulating cooling assembly and the exhaust valve, when the controller controls the exhaust valve to open, the high-pressure gas discharged by the exhaust valve drives the circulating cooling assembly to operate through the control assembly, and at this time, the cooling water in the cooling cylinder circulates.

[0010] As a further scheme of the present application, the circulating cooling assembly comprises a circulating pipe, a turbine pump and a condenser, the mounting table is fixedly provided with a mounting plate, the input end and the output end of the circulating pipe are communicated with the cooling cylinder, the turbine pump and the condenser are arranged on the circulating pipe and fixedly installed on the mounting plate, and the rotating shaft of the turbine pump is driven to intermittently rotate by the control assembly.

[0011] As a further scheme of the present application, the input end of the circulating pipe is communicated with the highest horizontal position of the cooling cylinder, and the output end of the circulating pipe is communicated with the lowest horizontal position of the cooling cylinder.

[0012] As a further scheme of the present application, the control assembly comprises a conveying pipe, a wind collecting pipe, a wind wheel and a synchronous belt, the mounting table is fixedly provided with a fixed plate, the wind wheel is rotatably installed on the fixed plate and the rotating shaft thereof is in transmission connection with the rotating shaft of the turbine pump through the synchronous belt, the wind collecting pipe is fixedly installed on the fixed plate and the air outlet thereof faces the blades of the wind wheel, and the wind collecting pipe is communicated with the exhaust valve through the conveying pipe.

[0013] As a further scheme of the present application, the number of the conveying pipes is two, the two conveying pipes are communicated with the two exhaust valves respectively, and the output ends of the two conveying pipes are communicated with the wind collecting pipe.

[0014] As a further scheme of the present application, the mounting plate is fixedly provided with a blowing pipe, the air outlet of the blowing pipe faces the turbine pump and the condenser, the air inlet of the blowing pipe is provided with a wind collecting assembly, and the wind collecting assembly cooperates with the wind collecting pipe.

[0015] As a further scheme of the present application, the wind collecting assembly comprises a wind collecting cover and a communication pipe, the wind collecting cover is fixedly installed on the fixed plate, the blades of the wind wheel and the air outlet of the wind collecting pipe are located in the wind collecting cover, and the wind collecting cover is communicated with the blowing pipe through the communication pipe.

[0016] As a further scheme of the present application, the mounting table is provided with an air cooling assembly, and the air cooling assembly cooperates with the cavity.

[0017] The present application has the following beneficial effects:

[0018] 1. In the application, the cooling water filled in the cooling cylinder can absorb heat from the outer walls of the first chamber and the second chamber by direct contact, 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 circulating cooling assembly to operate through the control assembly, thereby circulating the cooling water in the cooling cylinder. This ensures that the cooling water in the cooling cylinder is circulated after each compression of air, avoiding the temperature of the cooling water from rising to a temperature that cannot exchange heat with the first chamber and the second chamber, thereby ensuring that the cooling effect is always good.

[0019] 2. In the application, when the cooling water in the cooling cylinder is circulated, the cooled cooling water is drawn away at the same time, and the cooling water that has just been cooled enters the cooling cylinder. In this way, the cooling water in the cooling cylinder will form a cold water and hot water distribution situation. Since the density of cold water is greater than that of hot water, cold water will tend to sink below the cooling cylinder, and hot water will float above the cooling cylinder due to its smaller density. The input end of the circulating pipe is arranged above the cooling cylinder, so that hot water can be drawn away first, and cold water is injected into the cooling cylinder from below, ensuring that cold water accumulates below to avoid the situation where cold water sinks after being injected from above.

[0020] 3. In the application, a large amount of high-pressure gas flows out of the air blowing port of the air collecting pipe and hits the blades of the wind wheel, 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 the circulating cooling assembly can effectively remove heat from the chamber during continuous operation, preventing overheating. The energy of the high-pressure gas discharged from the chamber is used as a power source, realizing secondary utilization of energy and improving the overall energy utilization rate.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the application will be apparently and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0030] Please refer to Figures 1-6 The application is a kind of pneumatic supercharged air compressor, which comprises:

[0031] The gas storage tank 1 is fixedly installed with the mounting table 2, the mounting table 2 is fixedly installed with the cavity 3, the piston 4 is slidingly installed in the cavity 3, and the first chamber 5 and the second chamber 6 are respectively arranged at both ends of the piston 4, the first chamber 5 and the second chamber 6 are both communicated with the inflation valve 7, the suction valve 8, the exhaust valve 9 and the waste gas recovery valve 10, the inflation valve 7 is communicated with the high-pressure gas source equipment, the waste gas recovery valve 10 is communicated with the gas storage tank 1, and the inflation valve 7, the suction valve 8, the exhaust valve 9 and the waste gas recovery valve 10 are connected with the controller;

[0032] The cooling cylinder 11 is arranged on the outer wall of the first chamber 5 and the second chamber 6, and the cooling water is filled in each cooling cylinder 11, and each cooling cylinder 11 is provided with a circulating cooling assembly 12.

[0033] The control assembly 17 is arranged on the cavity 3 and connected with the circulating cooling assembly 12 and the exhaust valve 9, when the controller controls the exhaust valve 9 to open, the high-pressure gas discharged by the exhaust valve 9 drives the circulating cooling assembly 12 to operate through the control assembly 17, and at this time, the cooling water in the cooling cylinder 11 circulates.

[0034] In one 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 intake valve 8 is connected to an air filter. The high-pressure air source device can be a high-pressure air tank, the output end of another air compressor, etc. This embodiment does not make specific limitations here.

[0035] In practical application, the intake valve 8 is used to introduce outside air into the chamber to prepare for the next compression cycle. The high-pressure gas source equipment 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, allowing the compressed gas to leave the chamber and be transported to the gas storage tank 1. The exhaust valve 9 discharges 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 air introduction.

[0036] like Figure 3 Taking the example shown, at this time, all the inflation valves 7, intake valves 8, exhaust valves 9, and waste gas recovery valves 10 are closed. Then, the cavity 3 will enter the compression stage of the first chamber 5. First, the intake valve 8 on the first chamber 5 opens to introduce air and then closes. Then, the inflation valve 7 on the second chamber 6 opens, and high-pressure gas is injected into the second chamber 6, pushing the piston 4 to move towards the first chamber 5, thereby compressing the air in the first chamber 5. When the air in the first chamber 5 is compressed to the required pressure, the waste gas recovery valve 10 on the first chamber 5 opens to discharge the high-pressure gas into the gas storage tank 1. Then, the exhaust valve 9 on the second chamber 6 opens to discharge the high-pressure gas that pushed the piston 4, thus entering the compression stage of the second chamber 6. Whenever the first chamber 5 completes compression and exhaust, the second chamber 6 can carry out a new round of intake and compression. This cycle continues, allowing the piston 4 to move continuously back and forth, thereby achieving continuous compression of the gas.

[0037] And in the process of compressing gas, the collision frequency between gas molecules increases, and the kinetic energy improves, which is manifested as the temperature rising. When the high-pressure gas is injected into the chamber as a kinetic energy source, it will also generate heat when driving the movement of the chamber 3. Therefore, the temperature in the first chamber 5 and the second chamber 6 gradually rises in the continuous process of compressing gas. The cooling water filled in the cooling cylinder 11 can absorb heat from the outer wall of the first chamber 5 and the second chamber 6 through direct contact, thereby 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 assembly 12 to operate through the control assembly 17, thereby circulating the cooling water in the cooling cylinder 11. In this way, the cooling water in the cooling cylinder 11 can be circulated after each compression of air, thereby avoiding the temperature of the cooling water rising to a temperature that cannot be used for heat exchange with the first chamber 5 and the second chamber 6, and thereby ensuring that the cooling effect is always good.

[0038] As shown in Figures 1-3 As a preferred embodiment of the present application, the circulating cooling assembly 12 includes a circulating pipe 13, a turbine pump 14, and a condenser 15. The mounting plate 16 is fixedly installed on the mounting table 2. The input end and the output end of the circulating pipe 13 are in communication with the cooling cylinder 11. The turbine pump 14 and the condenser 15 are arranged on the circulating pipe 13 and are fixedly installed on the mounting plate 16. The rotating shaft of the turbine pump 14 is driven to rotate intermittently by the control assembly 17.

[0039] In one case of the present embodiment, it should be noted that the turbine pump 14 and the condenser 15 of the present application are both prior art, and the present application does not improve them. Therefore, their specific mechanical structure and circuit structure do not need to be disclosed, and the integrity of the present application is not affected.

[0040] In actual application, the rotating shaft of the turbine pump 14 is driven to rotate by the control assembly 17, thereby pumping and circulating the cooling water in the cooling cylinder 11 and the circulating pipe 13. In the circulation process, the cooling water is cooled by the condenser 15. In this way, the cooling water that absorbs heat and rises in temperature is cooled and then transported back into the cooling cylinder 11. In this way, the cooling water in the cooling cylinder 11 can exchange heat at the lowest temperature in the process of compressing air each time, thereby ensuring that the first chamber 5 and the second chamber 6 can be continuously cooled by heat absorption.

[0041] As shown in Figures 1-3 As a preferred embodiment of the present application, the input end of the circulating pipe 13 is in communication with the highest horizontal level of the cooling cylinder 11, and the output end of the circulating pipe 13 is in communication with the lowest horizontal level of the cooling cylinder 11.

[0042] In actual application, when the cooling water in the cooling cylinder 11 is circulated, the cooling water after being heated is extracted at the same time as the cooling water after being cooled enters the cooling cylinder 11, so that the cooling water in the cooling cylinder 11 forms a distribution of cold water and hot water. Since the density of the cold water is greater than that of the hot water, the cold water tends to sink below the cooling cylinder 11, and the hot water tends to float above the cooling cylinder 11 due to the smaller density. The input end of the circulating pipe 13 is arranged above the cooling cylinder 11, so that the hot water can be extracted first, and the cold water is injected into the cooling cylinder 11 from below, so that the cold water can be accumulated below to avoid the situation that the cold water is extracted after sinking from above.

[0043] As shown in Figures 1-4 As a preferred embodiment of the present application, the control assembly 17 includes a conveying pipe 18, a wind collecting pipe 19, a wind wheel 20, and a synchronous belt 21. The mounting table 2 is fixedly provided with a fixed plate 22, the wind wheel 20 is rotatably arranged on the fixed plate 22, and the rotating shaft of the wind wheel 20 is in driving connection with the rotating shaft of the turbine pump 14 through the synchronous belt 21. The wind collecting pipe 19 is fixedly arranged on the fixed plate 22, and the air outlet of the wind collecting pipe 19 faces the blades of the wind wheel 20. The wind collecting pipe 19 is in communication with the exhaust valve 9 through the conveying pipe 18.

[0044] In actual application, when the exhaust valve 9 is opened, the high-pressure gas after completing the task is discharged into the conveying pipe 18. The high-pressure gas has a high conveying speed due to the contained energy, and a large amount of high-pressure gas contained in the chamber is discharged from the air outlet of the wind collecting pipe 19 to hit the blades of the wind wheel 20, so that the wind wheel 20 rotates, and the rotating shaft of the turbine pump 14 is driven to rotate through the synchronous belt 21, so that the cooling water is circulated. This process ensures that the circulating cooling assembly 12 can effectively take away heat from the chamber during continuous operation to prevent overheating, and the energy of the high-pressure gas after completing the task discharged from the chamber is used as a power source to realize secondary utilization of energy and improve the overall utilization rate of energy.

[0045] As shown in Figures 1-4 As a preferred embodiment of the present application, the number of the conveying pipes 18 is two, and the two conveying pipes 18 are in communication with two exhaust valves 9, respectively. The output ends of the two conveying pipes 18 are in communication with the wind collecting pipe 19.

[0046] In actual application, the first chamber 5 and the second chamber 6 are communicated with the air collecting pipe 19 through the two conveying pipes 18, and during the alternating compression air process of the first chamber 5 and the second chamber 6, one chamber needs to discharge the high-pressure gas which has completed the task through the exhaust valve 9, so that the cooling water is circulated once, and the circulation of the cooling water is realized between the alternating compression air, and the heat generated by the compression air is removed.

[0047] As shown in Figures 1-6 , as a preferred embodiment of the present application, the mounting plate 16 is fixedly provided with a blowing pipe 26, the air outlet of the blowing pipe 26 is directed to the turbine pump 14 and the condenser 15, and the air inlet of the blowing pipe 26 is provided with an air collecting assembly 23 which cooperates with the air collecting pipe 19.

[0048] In actual application, the air blown out by the air collecting pipe 19 is collected through the air collecting assembly 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 the effect of cooling.

[0049] As shown in Figures 1-6 , as a preferred embodiment of the present application, the air collecting assembly 23 comprises an air collecting cover 24 and a communication pipe 25, the air collecting cover 24 is fixedly installed on the fixed plate 22, the blades of the air wheel 20 and the air outlet of the air collecting pipe 19 are located in the air collecting cover 24, and the air collecting cover 24 is communicated with the blowing pipe 26 through the communication pipe 25.

[0050] In actual application, the blades of the air wheel 20 and the air outlet of the air collecting pipe 19 are arranged in the air collecting cover 24, which not only makes the airflow blown out by the air collecting pipe 19 more concentrated on the blades of the air wheel 20, thereby accelerating the rotation of the air wheel 20, but also concentrates the airflow in the air collecting cover 24 and transports it to the blowing pipe 26 through the communication pipe 25, thereby further utilizing the energy of the high-pressure gas which has completed the task and further saving the cost.

[0051] As shown in Figure 1 , as a preferred embodiment of the present application, the mounting table 2 is provided with an air cooling assembly 27 which cooperates with the chamber 3.

[0052] In one case of the present embodiment, it should be noted that the air cooling assembly 27 of the present application comprises a cooling fan, a radiator, an air duct, a temperature control module and the like, all of which are prior art, and the present application does not improve them, therefore, the specific mechanical structure and circuit structure thereof do not need to be disclosed, and the integrity of the present application is not affected

[0053] In actual application, the air cooling assembly 27 can perform basic air cooling on the whole device, so that the whole device is in a lower temperature working environment, and the cooling water is used to cool the first chamber 5 and the second chamber 6, and the circulating cooling assembly 12 is used to circulate the cooling water, so that the anti-overheating capability of the whole device is improved.

[0054] The working principle of the present application is as follows: in the above embodiment of the present application, a pneumatic supercharged air compressor is provided, first, the air suction valve 8 on the first chamber 5 is opened to introduce air, and then the air filling valve 7 on the second chamber 6 is opened to inject high-pressure gas into the second chamber 6, which pushes the piston 4 to move towards the first chamber 5, so as to compress the air in the first chamber 5, until the air in the first chamber 5 is compressed to the required pressure, the waste gas recovery valve 10 on the first chamber 5 is opened to discharge the high-pressure gas 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, so as to enter the second chamber 6 for compression, whenever the first chamber 5 completes compression and exhaust, the second chamber 6 can perform a new round of air intake and compression, and the cooling water filled in the cooling cylinder 11 can absorb heat from the outer wall of the first chamber 5 and the second chamber 6 through direct contact, so as to avoid local overheating, and when the controller controls the exhaust valve 9 to open to discharge the high-pressure gas that has completed the task, the high-pressure gas discharged by the exhaust valve 9 drives the circulating cooling assembly 12 to operate through the control assembly 17, so as to circulate the cooling water in the cooling cylinder 11, so as to ensure that the cooling water in the cooling cylinder 11 is circulated after each compression of air, so as to avoid that the temperature of the cooling water is too high to exchange heat with the first chamber 5 and the second chamber 6.

[0055] The above describes one embodiment of the present application in detail, but the above description is only a preferred embodiment of the present application, and cannot be considered as limiting the scope of the present application. Any equivalent changes and improvements made according to the scope of the present application should still belong to the scope of the present application.
