Description

Technical Field

[0001] This invention belongs to the field of air compressor manufacturing technology, and specifically relates to a multi-functional single-cylinder air compressor. Background Technology

[0002] An air compressor, also known as an air compressor, is a device used to compress gases. Air compressors are similar in construction to water pumps. Most air compressors are reciprocating piston, rotary vane, or rotary screw types. When traditional air compressors are running, over 60% of the input energy is converted into waste heat, mainly discharged into the environment through heat sinks or fans, resulting in energy waste. Some manufacturers use water-cooling or oil-cooling systems, but these require additional energy (such as cooling pumps), and the heat is not reused.

[0003] A search revealed that the prior art includes a patent document with publication number CN214145805U and publication date of September 7, 2021, which discloses a single-cylinder air compressor, relating to the field of air compressor manufacturing technology. This application includes a shock-absorbing support mechanism, on which the air compressor body is fixed. The air compressor body includes a support plate and a support plate, and several shock-absorbing components are fixed between the support plate and the support plate. Each shock-absorbing component includes a sleeve and a first spring, which is located between the support plate and the support plate and fixedly connected to both. This invention, by setting the air compressor body on the shock-absorbing support mechanism and utilizing the several shock-absorbing components within the mechanism to dampen the air compressor body, and with the first and second springs in the air compressor body cooperating, achieves primary shock absorption of the air compressor body. Simultaneously, air inside the sleeve below the slider is ejected along several jet nozzles on the slider during the shock absorption process, consuming the energy from the impact, thereby achieving multi-stage shock absorption of the air compressor body, resulting in better shock absorption during use.

[0004] However, the device still has the following drawbacks: although it can achieve multi-stage vibration reduction of the air compressor body, making the air compressor body more effective in vibration reduction during use, the heat generated by the air compressor during operation is discharged into the external environment through the fan, causing environmental heat pollution and energy waste. Summary of the Invention

[0005] To address the above problems, the present invention provides a multifunctional single-cylinder air compressor, including a trolley, a protective cylinder on the trolley, an air compressor body inside the protective cylinder, and a heat recovery mechanism on the outer wall of the air compressor body.

[0006] The heat recovery mechanism includes several sets of heat-conducting fins and heat-absorbing tubes for storing cooling water to absorb waste heat. The heat-absorbing tubes are S-shaped and are attached to the outside of the air compressor body. The heat-absorbing tubes and several sets of heat-conducting fins are attached to each other, and one end of the heat-absorbing tube is connected to a water inlet pipe.

The inlet end of the water pump extends into the interior of the water tank, and the outlet end of the water pump is connected to an outlet pipe. The other end of the outlet pipe extends into the interior of the protective cylinder and is connected to the inlet pipe.

[0011] Furthermore, the other end of the heat absorption tube is connected to an overflow prevention tube, the overflow prevention tube is equipped with a liquid level sensor, and the overflow prevention tube is connected to a return pipe.

[0012] Furthermore, a buffer box is provided at the bottom of the trolley, and several sets of rollers are provided at the bottom of the buffer box. A spring is provided between the piston cylinder and the bottom of the trolley, and the spring is sleeved on the air guide pipe. A vacuum suction cup is provided at the bottom of the piston cylinder. A pressure relief pipe is connected to the side wall of the piston cylinder near the bottom. The other end of the pressure relief pipe extends into the buffer box, and a solenoid valve is provided on the pressure relief pipe.

[0013] Furthermore, a piston is provided inside the piston cylinder, and the piston is movably fitted with the inner wall of the piston cylinder. A graphite sealing ring is provided between the piston and the piston cylinder. A pressure sensor is provided at the bottom end of the piston. The top end of the piston is fixedly connected to the bottom end of the air guide pipe. The bottom end of the air guide pipe is connected to a second air blowing pipe, which passes through the center of the piston.

[0014] Furthermore, an air filter box is provided at the top of the outer wall of the protective cylinder, an air inlet pipe is provided at the top of the air filter box, an air guide pipe is provided at the bottom of the air filter box, and a filter blowing mechanism is provided on the air filter box.

[0015] Furthermore, the filter blowing mechanism includes a blowing pipe and a circulation pipe, both of which are connected to the interior of the air filter box. The bottom end of the blowing pipe is connected to a condenser pipe, and a guide bend is connected between the blowing pipe and the circulation pipe. A strip plate is fixedly connected to the inner wall of the blowing pipe, and a fan is installed on the strip plate. The air generated by the rotation of the fan blows into the interior of the air filter box.

[0016] Furthermore, a steam guide pipe is provided on one side of the filter box. The bottom end of the steam guide pipe passes through the protective cylinder and extends to the top of the outer wall of the air compressor body. The outlet end of the steam guide pipe is connected to a first air blowing pipe. The outlet end of the first air blowing pipe passes through the inner wall of the purge pipe and extends into the interior of the purge pipe.

[0017] Furthermore, a filter screen is installed on the inner wall of the air filter box, the purge pipe is located above the filter screen, the circulation pipe is located below the filter screen, a dust collection box is fixedly connected to the outer wall of the air filter box away from the purge pipe, a pull-out drawer is provided inside the dust collection box, and a dust guide groove is provided on the side wall of the air filter box adjacent to the dust collection box.

The first baffle plate is connected to the inner wall of the air filter box via a torsion spring. The first baffle plate is attached to one end of the blow pipe. A second baffle plate is provided at the top of the inner wall of the dust collection box. The second baffle plate is connected to the inner wall of the dust collection box via a torsion spring. The second baffle plate is attached to one side of the dust guide groove.

[0019] The beneficial effects of this invention are:

[0020] 1. Heat is absorbed through the heat absorption tube. The water inside the heat absorption tube absorbs heat and evaporates into water vapor. The water vapor is then introduced into the air guide pipe by controlling the three-way solenoid valve. The water vapor is then blown into the bottom of the piston cylinder through the second air blowing pipe, thereby pushing the piston cylinder to move the vacuum suction cup downwards. This causes the vacuum suction cup to adhere to the ground, effectively damping the air compressor body and limiting its movement to prevent it from shifting during operation. This effectively recovers and utilizes the heat generated by the air compressor body while achieving the effect of damping and limiting the movement of the device.

[0021] 2. The air pressure inside the piston cylinder is monitored by an air pressure sensor. When the air pressure inside the piston cylinder exceeds the preset value, the solenoid valve is opened to perform a first-stage pressure relief to prevent the cylinder from bursting due to excessive air pressure. At the same time, water vapor continuously enters the piston cylinder, and the water condensed inside the piston cylinder is pushed into the buffer tank through the pressure relief pipe for storage. Through air pressure monitoring and first-stage pressure relief operation, the stability of the piston cylinder operation is effectively improved.

[0022] 3. When the air pressure in the piston cylinder increases too quickly and the air pressure value still exceeds the preset value, the three-way solenoid valve is controlled to allow water vapor to enter the steam guide pipe, and then blow it into the filter cleaning mechanism through the first air blowing pipe. At the same time, the filter screen is cleaned while performing secondary pressure relief. The water vapor drives the fan to rotate, thereby realizing the automatic cleaning of the filter screen. The heat energy is converted into mechanical energy for recycling, effectively avoiding heat dissipation into the outside air and causing pollution. At the same time, there is no need to consume other energy for cleaning the filter screen, effectively achieving "energy saving and emission reduction".

[0023] 4. When the air compressor body stops working, the heat recovery mechanism no longer produces water vapor, and no more water vapor is injected into the piston cylinder. Through the pulling force of the spring, the piston cylinder and vacuum suction cup move upward, so that they are no longer attached to the ground. At this time, the trolley can be pushed to move the air compressor body to other positions for operation. As the piston cylinder moves upward, the piston scrapes the condensate attached to the inner wall of the piston cylinder to the bottom of the piston cylinder and injects it into the buffer tank through the pressure relief pipe, thereby effectively avoiding the residue of condensate in the piston cylinder.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] This invention provides a multi-functional single-cylinder air compressor, including a trolley 100; for example, such as... Figures 1-4 As shown.

[0036] The trolley 100 is equipped with a protective cylinder 200, which is made of heat-insulating material. The trolley 100 is equipped with a water tank 300, and a water pump 400 is installed on the water tank 300. The inlet end of the water pump 400 extends into the interior of the water tank 300, and the outlet end of the water pump 400 is connected to a water outlet pipe 410. The other end of the water outlet pipe 410 extends into the interior of the protective cylinder 200.

[0037] An air filter box 500 is provided at the top of the outer wall of the protective cylinder 200. An air inlet pipe 510 is provided at the top of the air filter box 500, and an air guide pipe 550 is provided at the bottom of the air filter box 500. A filter purging mechanism 520 is provided on the air filter box 500. The filter purging mechanism 520 includes a purging pipe 521 and a circulation pipe 522, both of which are connected to the interior of the air filter box 500. The bottom end of the purging pipe 521 is connected to a condenser pipe 524. The bottom end of the condenser pipe 524... Extending into the interior of the water tank 300, the purge pipe 521 and the circulation pipe 522 are connected by an air guide bend 523. A strip plate 525 is fixedly connected to the inner wall of the purge pipe 521. A fan 526 is installed on the strip plate 525. The air generated by the rotation of the fan 526 blows into the interior of the air filter box 500. A first wind baffle 527 is rotatably connected to the inner wall of the air filter box 500. The first wind baffle 527 is connected to the inner wall of the air filter box 500 by a torsion spring. The first wind baffle 527 is attached to one end of the purge pipe 521.

[0038] The air filter box 500 has a filter screen 530 installed on its inner wall. The blow pipe 521 is located above the filter screen 530, and the circulation pipe 522 is located below the filter screen 530. A dust collection box 540 is fixedly connected to the outer wall of the air filter box 500 away from the blow pipe 521. A pull-out drawer 541 is provided inside the dust collection box 540. A dust guide groove 511 is opened on the side wall of the air filter box 500 adjacent to the dust collection box 540. A second wind baffle 542 is provided at the top of the inner wall of the dust collection box 540. The second wind baffle 542 is connected to the inner wall of the dust collection box 540 by a torsion spring. The second wind baffle 542 is attached to one side of the dust guide groove 511.

[0039] A steam guide pipe 600 is provided at the center of the top of the outer wall of the protective cylinder 200. The outlet of the steam guide pipe 600 is connected to a first blowing pipe 610. The outlet of the first blowing pipe 610 extends into the interior of the blowing pipe 521 after penetrating the inner wall of the blowing pipe 521.

[0040] Specifically, steam enters the first blowing pipe 610 through the steam guide pipe 600, and then is blown into the purging pipe 521 through the first blowing pipe 610, driving the fan blades of the fan 526 to rotate, causing the fan 526 to drive air circulation, blowing up the first baffle plate 527, and allowing the airflow to enter the air filter box 500 to purge the upper surface of the filter screen 530. The flowing air blows air onto the second baffle plate 542, causing impurities and dust attached to the surface of the filter screen 530 to enter the pull-out drawer 541 in the dust collection box 540 through the dust guide groove 511 for collection.

[0041] Furthermore, when not purging, the tension of the torsion spring allows the first baffle plate 527 and the second baffle plate 542 to close the purging pipe 521 and the dust guide groove 511 respectively, thereby preventing dusty air from flowing back into the air filter box 500 and increasing the filtration burden on the filter screen 530. By setting the circulation pipe 522, the air blown into the air filter box 500 by the purging pipe 521 is all clean air, thereby effectively preventing dust from re-adhering to the surface of the filter screen 530 during the purging process.

[0042] Furthermore, water vapor is sprayed onto the surface of the fan 526, causing the fan 526 to rotate rapidly and generate centrifugal force, which causes condensate to be thrown out onto the inner wall of the blow pipe 521. Finally, it flows back into the water tank 300 through the condenser pipe 524 for recycling. The water vapor drives the fan 526 to rotate, thereby achieving automatic cleaning of the filter 530. The heat energy is converted into mechanical energy for recycling, effectively preventing heat from being dissipated into the outside air and causing pollution. At the same time, there is no need to consume other energy for cleaning the filter 530, effectively achieving energy conservation and emission reduction.

[0043] For example, such as Figures 5-8 As shown.

[0044] The protective cylinder 200 is equipped with an air compressor body 700 inside. The air compressor body 700 is connected to the air guide pipe 550. The air compressor body 700 is also connected to an air collecting pipe 900. The other end of the air collecting pipe 900 is connected to an air storage tank. The outer wall of the air compressor body 700 is equipped with a heat recovery mechanism 800.

[0045] The heat recovery mechanism 800 includes several sets of heat-conducting fins 810 and heat-absorbing pipes 820. The heat-absorbing pipes 820 are S-shaped and are attached to the outside of the air compressor body 700. The heat-absorbing pipes 820 and the several sets of heat-conducting fins 810 are attached to each other. One end of the heat-absorbing pipe 820 is connected to a water inlet pipe 830, which is connected to a water outlet pipe 410. The other end of the heat-absorbing pipe 820 is connected to an overflow prevention pipe 840. A liquid level sensor is installed inside the overflow prevention pipe 840. A return pipe 850 is connected to the overflow prevention pipe 840, and the other end of the return pipe 850 extends into the interior of the water tank 300.

[0046] The top end of the heat absorption tube 820 is connected to several sets of three-way solenoid valves 860. One set of output ends of the three-way solenoid valves 860 is connected to the inside of the steam guide tube 600, and the other set of output ends of the three-way solenoid valves 860 is connected to the air guide tube 870. The bottom ends of several sets of air guide tubes 870 all pass through the trolley 100 and extend to the bottom end of the trolley 100.

[0047] Specifically, when the air compressor body 700 is running, the filtered air enters the air compressor body 700 through the air guide pipe 550, and the air is compressed by the air compressor body 700. The compressed air is then discharged to the air storage tank through the air collection pipe 900 for use. The air compressor body 700 generates a large amount of heat when it is running. The heat is absorbed by the heat absorption pipe 820. The heat conduction area is increased by setting the heat conduction fins 810 to improve the heat absorption efficiency. The water in the heat absorption pipe 820 absorbs heat and evaporates into water vapor. The water vapor can be allowed to enter the air guide pipe 870 or the steam guide pipe 600 by controlling the three-way solenoid valve 860.

[0048] The water level in the heat absorption tube 820 is monitored by a liquid level sensor in the overflow pipe 840. When the water level is lower than the preset value, the water pump 400 is turned on to allow water to enter the heat absorption tube 820 through the inlet pipe 830, thereby maintaining the water level at the preset value. This allows the water in the heat absorption tube 820 to continuously evaporate and be replenished through the inlet pipe 830, thus achieving circulating heat absorption and effectively improving heat absorption efficiency. By setting a return pipe 850, when the water level in the heat absorption tube 820 exceeds the preset value, it flows out to the water tank 300 through the return pipe 850, preventing the water in the heat absorption tube 820 from being overloaded and causing the pipe to break.

[0049] The bottom of the trolley 100 is provided with a buffer box 110, the bottom of the buffer box 110 is provided with several sets of rollers 120, and the bottom of the trolley 100 is provided with several sets of vibration damping support mechanisms 130. The several sets of vibration damping support mechanisms 130 are respectively connected to a corresponding set of air ducts 870.

[0050] The vibration damping support mechanism 130 includes a piston cylinder 131. The bottom end of the air guide pipe 870 extends into the piston cylinder 131 and is movably fitted with the cylinder opening of the piston cylinder 131. A spring 132 is provided between the piston cylinder 131 and the bottom end of the trolley 100. The spring 132 is sleeved on the air guide pipe 870. A vacuum suction cup 133 is provided at the bottom end of the piston cylinder 131. A pressure relief pipe 134 is connected to the side wall of the piston cylinder 131 near the bottom end. The other end of the pressure relief pipe 134 extends into the buffer box 110. The pressure relief pipe 134 is equipped with a solenoid valve 135. The piston 136 is installed inside the piston cylinder 131. The piston 136 is in contact with the inner wall of the piston cylinder 131. A graphite sealing ring is provided between the piston 136 and the piston cylinder 131. A pressure sensor 137 is installed at the bottom end of the piston 136. The top end of the piston 136 is fixedly connected to the bottom end of the air guide pipe 870. The bottom end of the air guide pipe 870 is connected to a second air blowing pipe 871, which passes through the center of the piston 136.

[0051] Specifically, by controlling the three-way solenoid valve 860, water vapor is allowed to enter the air guide pipe 870. The water vapor is then blown into the bottom end of the piston cylinder 131 through the second air blowing pipe 871, thereby pushing the piston cylinder 131 to drive the vacuum suction cup 133 to move downward, so that the vacuum suction cup 133 is attached to the ground. This effectively reduces the vibration of the air compressor body 700 while limiting its movement, preventing it from deviating during operation.

[0052] Furthermore, the air pressure in the piston cylinder 131 is monitored by the air pressure sensor 137. When the air pressure in the piston cylinder 131 exceeds the preset value, the solenoid valve 135 is opened to perform a first-stage pressure relief to prevent the cylinder body from bursting due to excessive air pressure in the piston cylinder 131. At the same time, water vapor continuously enters the piston cylinder 131, and the water condensed in the piston cylinder 131 is pushed into the buffer tank 110 for storage through the pressure relief pipe 134.

[0053] Furthermore, when the air pressure in the piston cylinder 131 increases too quickly and the air pressure value still exceeds the preset value, the three-way solenoid valve 860 is controlled to allow water vapor to enter the steam guide pipe 600, and then blow it into the filter screen cleaning mechanism 520 through the first air blowing pipe 610 to perform secondary pressure relief while cleaning the filter screen 530.

[0054] Furthermore, when the air compressor body 700 stops working, the heat recovery mechanism 800 no longer generates water vapor, and no more water vapor is injected into the piston cylinder 131. Through the pulling force of the spring 132, the piston cylinder 131 and the vacuum suction cup 133 are moved upward, so that they are no longer attached to the ground. At this time, the trolley 100 can be pushed to move the air compressor body 700 to other positions for operation. While the piston cylinder 131 moves upward, the piston 136 scrapes the condensate attached to the inner wall of the piston cylinder 131 to the bottom of the piston cylinder 131 and injects it into the buffer tank 110 through the pressure relief pipe 134, thereby effectively avoiding the residue of condensate in the piston cylinder 131.

[0055] The working principle of the multifunctional single-cylinder air compressor proposed in this invention is as follows:

[0056] When the air compressor body 700 is running, the filtered air enters the air compressor body 700 through the air guide pipe 550. The air is compressed by the air compressor body 700, and the compressed air is discharged to the air storage tank through the air collection pipe 900 for use. The air compressor body 700 generates a lot of heat when running. The heat is absorbed by the heat absorption pipe 820. The heat conduction area is increased by setting the heat conduction fins 810 to improve the heat absorption efficiency. The water in the heat absorption pipe 820 absorbs heat and evaporates into water vapor. The water vapor can be allowed to enter the air guide pipe 870 or the steam guide pipe 600 by controlling the three-way solenoid valve 860.

[0057] By controlling the three-way solenoid valve 860, water vapor is allowed to enter the air guide pipe 870. The water vapor is then blown into the bottom end of the piston cylinder 131 through the second air blowing pipe 871, thereby pushing the piston cylinder 131 to move the vacuum suction cup 133 downward, so that the vacuum suction cup 133 is attached to the ground. This effectively dampens the air compressor body 700 while limiting its movement, preventing it from deviating during operation.

[0058] The air pressure in the piston cylinder 131 is monitored by the air pressure sensor 137. When the air pressure in the piston cylinder 131 exceeds the preset value, the solenoid valve 135 is opened to release pressure in the first stage, so as to avoid the cylinder body from bursting due to excessive air pressure in the piston cylinder 131. At the same time, water vapor continues to enter the piston cylinder 131, and the water condensed in the piston cylinder 131 is pushed into the buffer tank 110 for storage through the pressure relief pipe 134.

[0059] When the air pressure in the piston cylinder 131 increases too quickly and the air pressure value still exceeds the preset value, the three-way solenoid valve 860 is controlled to allow water vapor to enter the steam guide pipe 600, and then blow it into the filter screen cleaning mechanism 520 through the first air blowing pipe 610 to perform secondary pressure relief while cleaning the filter screen 530.

[0060] Steam enters the first blowing pipe 610 through the steam guide pipe 600, and then is blown into the purging pipe 521 through the first blowing pipe 610, driving the fan blades of the fan 526 to rotate, causing the fan 526 to drive air circulation, blowing up the first baffle plate 527, and allowing the airflow to enter the air filter box 500 to purge the upper surface of the filter screen 530. The flowing air blows air onto the second baffle plate 542, causing impurities and dust attached to the surface of the filter screen 530 to enter the pull-out drawer 541 in the dust collection box 540 through the dust guide groove 511 for collection.

[0061] When not purging, the tension of the torsion spring allows the first baffle plate 527 and the second baffle plate 542 to close the purging pipe 521 and the dust guide groove 511 respectively, thereby preventing dusty air from flowing back into the air filter box 500 and increasing the filtration burden on the filter screen 530. By setting the circulation pipe 522, the air blown into the air filter box 500 by the purging pipe 521 is all clean air, thereby effectively preventing dust from re-adhering to the surface of the filter screen 530 during the purging process.

[0062] Water vapor is sprayed onto the surface of fan 526, causing fan 526 to rotate rapidly and generate centrifugal force, which causes condensate to be thrown out onto the inner wall of purge pipe 521. Finally, it flows back into water tank 300 through condenser pipe 524 for recycling. Water vapor drives fan 526 to rotate, thereby achieving automatic cleaning of filter screen 530. Heat energy is converted into mechanical energy for recycling, effectively preventing heat from being dissipated into the outside air and causing pollution. At the same time, there is no need to consume other energy for cleaning filter screen 530, effectively achieving "energy saving and emission reduction".

[0063] When the air compressor body 700 stops working, the heat recovery mechanism 800 no longer generates water vapor, and no more water vapor is injected into the piston cylinder 131. Through the pulling force of the spring 132, the piston cylinder 131 and the vacuum suction cup 133 are moved upward, so that they are no longer attached to the ground. At this time, the trolley 100 can be pushed to move the air compressor body 700 to other positions for operation. While the piston cylinder 131 moves upward, the piston 136 scrapes the condensate attached to the inner wall of the piston cylinder 131 to the bottom of the piston cylinder 131 and injects it into the buffer tank 110 through the pressure relief pipe 134, thereby effectively avoiding the residue of condensate in the piston cylinder 131.
