Description

Technical Field

[0001] This utility model relates to the field of air compressor equipment technology, specifically an air compressor with an automatically cleanable radiator. Background Technology

[0002] Air compressors, as core equipment in the industrial field, are widely used in equipment manufacturing, automotive, metallurgy, power, electronics, medical, and textile industries. During operation, if the heat generated by compressed air cannot be dissipated in time, it can lead to overheating, causing problems such as lubricating oil carbonization, bearing wear, and seal failure, and even shutdown. The radiator, as a key heat dissipation component of the air compressor, transfers heat to the external environment through heat conduction, convection, and radiation; its performance directly affects the stability and lifespan of the equipment. However, radiators easily accumulate dust, oil, and fiber debris during use, which can clog the gaps and reduce heat dissipation efficiency. To ensure the normal operation of the radiator, current cleaning methods generally involve manual disassembly and cleaning, requiring periodic shutdowns for radiator removal, which is time-consuming, labor-intensive, and inefficient, incurring significant cleaning costs. Utility Model Content

[0003] The purpose of this invention is to provide an air compressor that can automatically clean the radiator, which can perform all-round cleaning of the radiator through a blower without stopping the machine and disassembling the radiator, thus solving the problems in the prior art.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: an air compressor with an automatically cleanable radiator, including a casing, an air compressor pump, an oil-gas separator, a radiator, and an oil filter installed inside the casing; a mixed compressed air pipeline is installed between the air compressor pump and the oil-gas separator; a compressed air pipeline is installed between the oil-gas separator and the radiator; an oil return pipeline is installed between the oil-gas separator and the oil filter; an oil cooling inlet pipe and an oil cooling return pipe are installed between the oil filter and the radiator; an oil discharge pipe is installed between the oil filter and the air compressor pump; a radiator bracket is installed inside the casing, and the radiator is installed in the radiator bracket; a fan is installed in the radiator bracket on the side away from the radiator. A mesh cover is installed on the chassis at the location of the heat dissipation bracket. The heat sink is located between the fan and the mesh cover. An automatic cleaning device is also installed on the heat dissipation bracket between the heat sink and the fan. The automatic cleaning device includes vertically arranged blow pipes. The length of the blow pipes is the same as the width of the heat sink. The blow pipes can move back and forth along the length of the heat sink. Flexible water supply pipes and flexible air supply pipes are installed on the blow pipes. The blow pipes can spray water and air onto the heat sink for all-round cleaning. Several interconnected first sewage pipes are installed at the bottom of the heat dissipation bracket. A water collection tank is installed on the chassis at the bottom of the mesh cover. Several interconnected second sewage pipes are installed at the bottom of the water collection tank. The heat dissipation bracket contains two parallel drive rods, each vertically positioned at both ends of the radiator's length. Both ends of the drive rods are fixed to the heat dissipation bracket via bearing seats. Each drive rod has a pulley, and a drive belt is fitted between corresponding pulleys on the two drive rods. A blower pipe is fixed to the drive belt. A drive motor is installed at the end of one drive rod that extends beyond the bearing seat. When the drive motor starts, it drives the blower pipe to reciprocate along the length of the radiator via the drive belt. The blower pipe contains isolated water and air chambers. A flexible water supply pipe connects to the water chamber, and a flexible air supply pipe connects to the air chamber. A detachable cover plate is installed on the blower pipe, located above the air chamber. Several water nozzles connected to the water chamber are mounted on the blower pipe, and several air nozzles connected to the air chamber are mounted on the cover plate. The water nozzles and air nozzles are coaxially arranged opposite each other. The radiator includes a heat dissipation coil with several vertically arranged heat dissipation fins. A manual cleaning mechanism is installed on the heat dissipation bracket between the radiator and the automatic cleaning device. The manual cleaning mechanism can clean the gaps between the heat dissipation fins. The manual cleaning mechanism includes a U-shaped frame with a baffle at the top and a handle on the baffle. Several elastic hooks are installed at the bottom of the U-shaped frame, and each elastic hook is located between adjacent heat dissipation fins. A vertical guide slot frame that cooperates with the U-shaped frame is installed inside the heat dissipation bracket. The top of the heat dissipation bracket has a through slot that allows the elastic hooks to pass through. The area of ​​the baffle is larger than the area of ​​the through slot, and the baffle is always located on the heat dissipation bracket above the through slot.

[0005] The positive effects of this utility model are as follows: The air compressor with automatic radiator cleaning described in this utility model uses a reciprocating blowing pipe as an automatic cleaning device, combined with the water and air supply functions of the flexible water supply pipe and air supply pipe, to achieve automated control of the cleaning process. It can remove dust, oil, and other impurities from the radiator surface and the gaps between the heat dissipation fins in real time without stopping the machine, avoiding equipment overheating problems caused by radiator blockage. The setting of sewage pipe and water collection tank inside the device can uniformly collect and treat the sewage attached to the radiator, avoiding pollution of the equipment by leaving it inside the device. The cleaning process does not require frequent shutdown maintenance, which greatly reduces labor costs and downtime losses. At the same time, automatic cleaning reduces manual intervention, improves cleaning efficiency, reduces the risk of equipment damage due to improper operation, further saves maintenance costs, significantly improves the overall operational stability and reliability of the equipment, and extends the service life of the equipment.

[0017] This utility model describes an air compressor with an automatically cleanable radiator, such as... Figure 1 and Figure 2 As shown, it includes a housing 1, inside which an air compressor pump 2, an oil-gas separator 3, a radiator 4, and an oil filter 5 are installed.

[0018] A mixed compressed air pipeline 6 is installed between the air compressor pump 2 and the oil-gas separator 3; a compressed air pipeline 7 is installed between the oil-gas separator 3 and the radiator 4; an oil return pipeline 8 is installed between the oil-gas separator 3 and the oil filter 5; an oil cooling inlet pipe 9 and an oil cooling return pipe 10 are installed between the oil filter 5 and the radiator 4; and an oil discharge pipe 11 is installed between the oil filter 5 and the air compressor pump 2.

[0019] The air compressor pump 2 compresses the intake gas to increase the air pressure. The compressed high-pressure gas, mixed with water, oil and other impurities, enters the oil-gas separator 3 through the mixed compressed gas pipeline 6. After separation, the pure high-pressure gas enters the radiator 4 through the compressed gas pipeline 7 for cooling. After cooling, it can provide a high-pressure gas source for other devices. The separated oil enters the oil filter 5 through the oil return pipeline 8 for impurity filtration. After filtration, the oil enters the radiator 4 through the oil cooling inlet pipe 9 for cooling. After cooling, the oil flows back to the oil filter 5 through the oil cooling return pipe 10, and then flows back to the air compressor pump 2 through the oil discharge pipe 11. This completes the oil separation, cooling and return cycle.

[0020] To facilitate the installation and heat exchange of radiator 4, such as Figure 3 and Figure 4 As shown, a heat dissipation bracket 12 is installed inside the chassis 1, and the heat sink 4 is installed in the heat dissipation bracket 12. A fan 13 is installed in the heat dissipation bracket 12 on the side away from the heat sink 4. A mesh cover 14 is installed on the chassis 1 at the position of the heat dissipation bracket 12, and the heat sink 4 is located between the fan 13 and the mesh cover 14.

[0021] The heat dissipation bracket 12 provides a stable mounting position for the heat sink 4. The fan 13 can blow air to cool the heat sink 4. The mesh cover 14 can smoothly expel the high-temperature gas inside the chassis 1, while the mesh structure prevents external debris from entering the chassis.

[0022] The fan 13 can be started and stopped by a control switch, and it is also equipped with a reversing switch. When the fan 13 rotates forward, it can blow towards the heat sink 4 to cool the heat sink 4. When the fan 13 rotates in reverse, it can blow towards the air intake on the chassis 1 to blow away the explosive sponge on the air intake and remove the debris attached to the explosive sponge, so as to ensure that the outside air can smoothly enter the chassis 1.

[0023] To enable cleaning of the radiator 4 without disassembly, an automatic cleaning device is installed on the heat dissipation bracket 12 between the radiator 4 and the fan 13. This automatic cleaning device includes a vertically arranged blowpipe 15, the length of which is the same as the width of the radiator 4. The blowpipe 15 can reciprocate along the length of the radiator 4. This reciprocating movement can be achieved through existing screw and nut mechanisms, gear and rack mechanisms, or other transmission mechanisms. The blowpipe 15 is equipped with a flexible water supply pipe 16 and a flexible air supply pipe 17, which can be made from existing corrugated pipes. One end of the flexible water supply pipe 16 is connected to a water pump, and one end of the flexible air supply pipe 17 is connected to an air pump, allowing for the supply of water and air to the blowpipe 15 respectively. This enables the blowpipe 15 to blow high-pressure gas or high-pressure water mist onto the radiator 4 for comprehensive cleaning.

[0024] To facilitate the recycling and treatment of residual dripping cleaning water on the radiator 4, several interconnected first wastewater pipes 28 can be installed at the bottom of the radiator bracket 12. A water collection tank 29 is installed on the chassis 1 at the bottom of the mesh cover 14, and several interconnected second wastewater pipes 30 are installed at the bottom of the water collection tank 29. The first wastewater pipes 28 and the second wastewater pipes 30 are located at the bottom of the inner and outer sides of the radiator 4, respectively, allowing for unified recycling and treatment of cleaning wastewater. The design of the wastewater pipes and the water collection tank 29 facilitates the collection and discharge of cleaning wastewater, preventing wastewater from contaminating the inside of the equipment.

[0025] With its automatic cleaning device, this air compressor can remove dust, oil, and other impurities from the surface of radiator 4 in real time without shutting down, preventing overheating caused by radiator blockage. This not only reduces the risk of malfunctions such as lubricant carbonization, bearing wear, and seal failure caused by high temperatures, but also significantly improves the overall operational stability and reliability of the equipment, extending its service life. After cleaning the surface of radiator 4, heat transfer efficiency is significantly improved, allowing the heat generated by compressed air to be transferred to the external environment more quickly, thereby reducing the operating temperature of the equipment. This not only reduces energy consumption increases caused by high temperatures but also improves the overall energy efficiency of the air compressor, meeting the environmental protection requirements of energy conservation and emission reduction.

[0026] Furthermore, in order to achieve the reciprocating movement of the blow pipe 15 along the length of the radiator 4, such as... Figure 5As shown, two drive rods 18 arranged side by side can be installed inside the heat dissipation bracket 12. Each drive rod 18 is vertically arranged at both ends of the length direction of the radiator 4. Both ends of the drive rod 18 in the length direction are fixed to the heat dissipation bracket 12 through bearing seats 19.

[0027] The transmission rod 18 is equipped with pulleys 20, and a transmission belt 21 is installed between the corresponding pulleys 20 on the two transmission rods 18. The blowpipe 15 is fixed on the transmission belt 21. The transmission belt 21 not only provides a mounting position for the blowpipe 15, but also drives the two transmission rods 18 to rotate synchronously. A drive motor 22 is installed at one end of one of the transmission rods 18 that protrudes from the bearing housing 19. When the drive motor 22 is started, it can drive the blowpipe 15 to reciprocate along the length of the radiator 4 via the transmission belt 21.

[0028] The start, stop, and forward / reverse rotation of the drive motor 22 can be controlled by an internal controller, with feedback monitoring via an internal temperature sensor. When the temperature sensor detects a significant temperature rise, it activates the drive motor 22, moving the blower pipe 15 to clean the radiator 4. The automatic cleaning device uses the drive motor 22 and transmission belt 21 to achieve the reciprocating movement of the blower pipe 15. Combined with the water and air supply functions of the flexible water supply pipe 16 and flexible air supply pipe 17, it achieves automated control of the cleaning process, ensuring comprehensive and efficient cleaning and enhancing the automation and intelligence level of the equipment.

[0029] Furthermore, in order to achieve separate storage of air and water within the blowpipe 15, and to allow for separate high-pressure air cleaning, separate high-pressure water mist cleaning, or high-pressure air-water mixed cleaning of the radiator 4 according to actual cleaning needs, such as... Figure 6 and Figure 7 As shown, the blow pipe 15 may have a water storage chamber 23 and an air storage chamber 24 that are isolated from each other. The flexible water supply pipe 16 is connected to the water storage chamber 23, and the flexible air supply pipe 17 is connected to the air storage chamber 24.

[0030] A detachable cover plate 25 is provided on the blow pipe 15. The cover plate 25 is located on the upper side of the air storage chamber 24, which is located on the upper side of the water storage chamber 23. Several water nozzles 26 connected to the water storage chamber 23 are installed on the blow pipe 15. The water nozzles 26 can pass outward through the air storage chamber 24 and the cover plate 25. Several air nozzles 27 connected to the air storage chamber 24 are installed on the cover plate 25. The water nozzles 26 and air nozzles 27 are arranged coaxially and correspondingly.

[0031] The above-mentioned arrangement not only separates the storage of air and water in the blow pipe 15, but also, due to the coaxial arrangement of the water nozzle 26 and air nozzle 27, ensures that the high-pressure air and high-pressure water mist do not interfere with each other when they are sprayed out, which can effectively improve the comprehensiveness and thoroughness of cleaning the radiator 4.

[0032] The aforementioned automated cleaning device reduces the need for manual contact with high-temperature equipment and cleaning agents, thus lowering the safety risks for operators. Simultaneously, the automation of the cleaning process reduces the workload of operators and improves their comfort. This design allows for adjustment of parameters such as the cleaning frequency and water / air pressure of the blowpipe 15 according to different working conditions and cleaning needs, demonstrating strong adaptability. Furthermore, the structural design of the automated cleaning device facilitates future upgrades and expansions, such as adding sensors to monitor the radiator's cleaning status and enabling remote control.

[0033] like Figure 8-10 As shown, the radiator 4 includes a heat dissipation coil 31, and the heat dissipation coil 31 is provided with a number of vertically arranged heat dissipation fins 32. The heat dissipation fins 32 realize the cooling and heat exchange in the heat dissipation coil 31. The heat dissipation fins 32 are arranged relatively tightly. If the air compressor is used during a period with a lot of airborne fluff, the probability of the heat dissipation fins 32 being blocked will increase significantly. The automatic cleaning device alone may not be able to thoroughly clean the dirt trapped between the heat dissipation fins 32.

[0034] To address the aforementioned issues, a manual cleaning mechanism can be installed on the heat dissipation bracket 12 between the radiator 4 and the automatic cleaning device. This manual cleaning mechanism can thoroughly clean the gaps between the heat dissipation fins 32. The manual cleaning mechanism includes a U-shaped frame 33, with a baffle 34 at its upper part and a handle 35 mounted on the baffle 34. The baffle 34 serves as a limiting mounting mechanism for the manual cleaning mechanism on the heat dissipation bracket 12, while the handle 35 allows operators to manually pull upwards to clean the gaps between the heat dissipation fins 32.

[0035] Several elastic hooks 36 are installed at the bottom of the U-shaped frame 33. Each elastic hook 36 is located between adjacent heat dissipation fins 32. When the elastic hooks 36 move upward, they can remove and clean the debris blocking the heat dissipation fins 32. Furthermore, due to the elasticity of the elastic hooks 36 themselves, such as... Figure 11 As shown, after the elastic hook 36 moves upward and comes into contact with the heat dissipation coil 31, it can bend and deform, without making hard contact with the heat dissipation coil 31 and causing damage to the surface. At the same time, it can also ensure the normal upward movement of the elastic hook 36 itself, so as to clean the gaps between the heat dissipation fins 32.

[0036] To achieve vertical movement guidance of the U-shaped frame 33, a vertical movement guide bracket 37 that cooperates with the U-shaped frame 33 is installed inside the heat dissipation bracket 12. The top of the heat dissipation bracket 12 is provided with a through slot 38 through which the elastic hook rod 36 can pass. The area of ​​the baffle 34 is larger than the area of ​​the through slot 38. The baffle 34 is always located on the heat dissipation bracket 12 above the through slot 38.

[0037] Under normal conditions, the U-shaped frame 33 is located inside the heat dissipation bracket 12, the baffle 34 is located on the heat dissipation bracket 12 above the through slot 38, and the elastic hook rod 36 is located at the bottom of the heat dissipation fins 32. The arrangement of the U-shaped frame 33 provides space between the heat dissipation fins 32 and the automatic cleaning device, and will not interfere with the automatic cleaning of the blow pipe 15. When manual cleaning is required, the operator only needs to pull the handle 35 upwards. Under the guidance of the vertical guide slot frame 37, the elastic hook rod 36 moves upwards between the heat dissipation fins 32, and the blockage between the heat dissipation fins 32 is thoroughly removed by the elastic hook rod 36. The addition of the manual cleaning mechanism provides an alternative cleaning solution and further enhances the convenience of cleaning the equipment.

[0038] Regular automatic cleaning removes impurities from the surface of the radiator 4 and the gaps between the heat dissipation fins 32, reducing corrosion and wear caused by impurity accumulation and thus extending the service life of the radiator 4. This not only reduces the replacement frequency of the radiator 4 but also reduces equipment downtime caused by radiator 4 malfunctions.

[0039] In summary, the air compressor with an automatically cleaning radiator of this utility model significantly improves the operational stability, reliability, energy efficiency, and automation level of the equipment through the innovative design of the automatic cleaning device, while reducing maintenance costs and downtime, resulting in significant economic and social benefits.
