Description

Technical Field

[0001] The invention relates to the technical field of air compressors, in particular to an energy-saving vertical air compressor. Background Art

[0002] Vertical air compressors have become a key direction for industrial energy-saving transformation due to their compact layout and low vibration characteristics. In particular, the piston structure is widely used due to its high compression ratio characteristics. However, the reciprocating motion of the piston assembly needs to rely on lubricating oil to reduce friction loss. Traditional lubrication systems have problems such as oversupply of oil and high-temperature deterioration, which not only increases viscous resistance but also leads to waste of heat energy. Although the vertical design reduces pumping energy consumption through gravity-assisted oil supply, the coordinated optimization of lubrication efficiency and thermal management is still the key to breaking through the energy efficiency bottleneck.

[0003] For example, the patent application number "CN112065687B" proposes a piston air compressor and its use method, which effectively realizes the function of reciprocating extraction of air in the cylinder body through the piston plate. At the same time, the ball bearings on the piston plate can apply lubricating oil to the inner wall of the cylinder body, thereby effectively reducing the friction between the sealing gasket and the cylinder body, ensuring the use effect of the sealing gasket.

[0004] However, in actual application, the above patent still has some defects. Although its ball-type oiling structure can achieve local lubrication of the cylinder wall, the continuous friction between the ball and the inner wall of the cylinder will accelerate the consumption of lubricating oil, resulting in insufficient continuity of lubrication; at the same time, the lubricating oil is replenished in the groove, causing key friction pairs such as the crank connecting rod end to be in the lubrication blind spot for a long time. This dual defect of local coverage and inefficient replenishment seriously limits the energy efficiency stability of vertical air compressors under high-frequency conditions.

[0021] 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.

[0022] An energy-saving vertical air compressor, such as Figure 1-Figure 8 As shown, it includes a chassis 1, an oil bin 2 is provided inside the chassis 1, a piston bin 3 is provided on the top of the oil bin 2, a piston body 4 is slidably provided inside the piston bin 3, a drainage chute 5 is symmetrically provided on the inner bottom of the oil bin 2, an arc-shaped oil collecting groove 6 is provided on the inner bottom of the drainage chute 5, support rods 7 are symmetrically fixedly connected inside the oil bin 2, one end of the two support rods 7 is rotatably connected to a crankshaft 8, a connecting rod 9 is hinged at the bottom of the piston body 4, the bottom of the connecting rod 9 is hinged to the crankshaft 8, an oil pumping cylinder 10 is rotatably connected inside the arc-shaped oil collecting groove 6, a pair of circumferential guide vane rings 11 are fixedly connected inside the oil pumping cylinder 10, and the inner blades of the two circumferential guide vane rings 11 have opposite deflection directions; One end of the chassis 1 is equipped with an operating mechanism for driving the crankshaft 8 to drive the pumping cylinder 10 to rotate. The interior of the oil tank 2 is provided with a guiding component for guiding the lubricating oil to the hinged ends of the crankshaft 8, the connecting rod 9 and the piston body 4. The interior of the oil tank 2 is equipped with a monitoring component.

[0023] When in use, first, the crankshaft 8 is driven to rotate by starting the operating mechanism, and the pumping cylinder 10 is driven to rotate at the same time, and the crankshaft 8 is caused to rotate around the hinge shaft to pull one end of the connecting rod 9. At the same time, the other end of the connecting rod 9 pulls the piston body 4 to reciprocate along the inner wall of the piston chamber 3. While the pumping cylinder 10 is rotating, the lubricating liquid inside the oil tank 2 is guided to flow into the arc-shaped oil collecting tank 6 for collection through the drainage chute 5 and the action of gravity. In this way, the lubricating liquid flowing into the arc-shaped oil collecting groove 6 is driven by the pumping cylinder 10 to rotate the circumferential guide vane ring 11. The blades in the circumferential guide vane ring 11 far away from the end of the connecting rod 9 are designed with negative curvature. When the pumping cylinder 10 rotates at ≥2500rpm, a negative pressure area is generated to suck the lubricating oil in the arc-shaped oil collecting groove 6; the blades in the circumferential guide vane ring 11 close to the end of the connecting rod 9 are designed with positive curvature. Through the centrifugal supercharging effect, the oil sucked into the pumping cylinder 10 is pushed to the hinged end of the support rod 7, the crankshaft 8, and the connecting rod 9 through the guide component, and the inner wall of the piston chamber 3 for lubrication. Then, as the piston body 4 reciprocates along the inner wall of the piston chamber 3, the lubricating oil is evenly coated between the piston body 4 and the piston chamber 3, and the motion trajectory of the piston body 4 is fully lubricated to reduce motion friction. At the same time, the oil pressure state of the lubricating oil is monitored in real time through the monitoring component to ensure the stability and continuity of the lubrication process and avoid energy efficiency loss caused by excessive or insufficient lubrication. This facilitates the stable drainage of lubricating oil to between the support rod 7 and the crankshaft 8, the crankshaft 8 and the connecting rod 9, and the piston body 4 and the piston chamber 3 when the piston body 4 is driven to reciprocate along the inner wall of the piston chamber 3, thereby effectively reducing the lubrication blind area of ​​the lubricating oil and improving the lubrication efficiency and stability of the device.

[0024] like Figure 2-Figure 5 , Figure 8 As shown, the operating mechanism includes a transmission gear 12 fixedly connected to one end of the pumping cylinder 10, a transmission gear 2 13 is symmetrically fixedly connected to one end of the crankshaft 8, a transmission gear 3 14 meshing with the transmission gear 2 13 is rotatably connected to one end of the support rod 7, a transmission gear 4 15 meshing with the transmission gear 1 12 is fixedly connected to one end of the transmission gear 3 14, and an operating component for driving the crankshaft 8 to rotate is installed at one end of the chassis 1; Among them, the transmission ratio of the transmission gear 2 13 and the transmission gear 3 14 is 2:1, and the transmission ratio of the transmission gear 4 15 and the transmission gear 1 12 is 1.5:1, and the transmission gear 1 12, the transmission gear 2 13, the transmission gear 3 14 and the transmission gear 4 15 all adopt a helical tooth design with a helical angle of 25°; Moreover, the operating assembly includes an energy supply motor 17 fixedly connected to the inside of the chassis 1, the output end of the energy supply motor 17 passes through the chassis 1 and is fixedly connected to a driving gear 18, one end of the crankshaft 8 passes through the chassis 1 and is fixedly connected to a driven gear 19, and a synchronous belt 20 is provided on the outer periphery of the driving gear 18 and the driven gear 19; Furthermore, a centrifugal filter 33 is fixedly connected to the input end of the oil pump 10. The base material of the centrifugal filter 33 is titanium alloy, and an oleophobic coating is provided on its surface.

[0025] When in use, first, starting the energy supply motor 17 can drive the driving gear 18 to rotate, and then the driven gear 19 is rotated synchronously through the synchronous belt 20. Subsequently, the driven gear 19 drives the crankshaft 8 to rotate, causing the two transmission gears 2 13 to rotate synchronously and mesh with the transmission gear 3 14. At the same time, the transmission gear 3 14 drives the transmission gear 4 15 to mesh with the transmission gear 1 12, and then the transmission gear 1 12 drives the pumping cylinder 10 to rotate. At the same time, the transmission ratio of the transmission gear 2 13 to the transmission gear 3 14 is set to 2:1, and the transmission ratio of the transmission gear 4 15 to the transmission gear 12 is set to 1.5:1. Through two-stage speed change, the rotation speed of the pumping cylinder 10 can reach 3 times that of the crankshaft 8, ensuring the centrifugal separation efficiency of the lubricating oil and improving the delivery flow rate of the lubricating oil. At the same time, the helical gear design with a helical angle of 25° adopted by the transmission gear 1 12, the transmission gear 2 13, the transmission gear 3 14 and the transmission gear 4 15 makes the transmission gear 1 12 and the transmission gear 2 13, the transmission gear 3 14 and the transmission gear 4 15 mesh with multiple teeth simultaneously through progressive meshing, which significantly improves the stability. And while driving the pumping cylinder 10 to rotate at high speed, the pumping cylinder 10 drives the centrifugal filter 33 to rotate synchronously, and before the lubricating oil enters the pumping cylinder 10, it is first intercepted and filtered by the centrifugal filter 33, and the centrifugal filter 33 is shaken off the foreign matter attached to the surface at a speed of 3000rpm. At the same time, the oleophobic coating reduces the amount of oil adhesion by 40%, avoiding the clogging of the centrifugal filter 33 under low temperature conditions.

[0026] like Figure 4-Figure 7 As shown, the guide assembly includes a guide channel 21 opened inside the support rod 7, a guide ring groove 22 is opened at the connecting end of the support rod 7 and the crankshaft 8, the input end of the guide channel 21 is connected to the inside of the arc-shaped oil collecting groove 6, an oil injection hole 23 is symmetrically opened at one end of the crankshaft 8, the oil injection hole 23 is installed inside the guide ring groove 22, a guide channel 24 connected to the two oil injection holes 23 is opened inside the crankshaft 8, an oil injection hole 25 connected to the middle section of the guide channel 2 24 is opened at the hinged end of the crankshaft 8 and the connecting rod 9, a guide ring groove 26 connected to the oil injection hole 25 is opened at the hinged end of the connecting rod 9 and the crankshaft 8, a guide channel 3 27 connected to the guide ring groove 26 is opened inside the connecting rod 9, and an oil injection hole 28 connected to the guide channel 3 27 is opened at the hinged end of the connecting rod 9 and the piston body 4; Among them, the monitoring component includes an oil filling nozzle 29 fixedly connected to the inner side of the oil tank 2, an oil filling valve 30 fixedly connected to the outer side of the chassis 1, the output end of the oil filling valve 30 fixedly connected to the oil storage tank 31, the output end of the oil storage tank 31 is connected to the oil filling nozzle 29, the connecting end of the oil injection hole 28 and the guide channel three 27 is fixedly connected to the oil pressure sensor 32, and the oil pressure sensor 32 is electrically connected to the oil storage tank 31.

[0027] When in use, when the operating mechanism is started to drive the pumping cylinder 10 to drive the circumferential guide vane ring 11 to rotate, and the lubricating oil liquid inside the oil tank 2 is pushed into the inside of the pumping cylinder 10, the lubricating oil liquid is pushed by the circumferential guide vane ring 11, passes through the guide channel 1 21 and enters the inside of the guide ring groove 1 22. This ensures that the hinged end of the crankshaft 8 and the support rod 7 is lubricated. Subsequently, the lubricating oil liquid passes through the oil injection hole 1 23 from the inside of the guide ring groove 1 22 into the guide channel 2 24, and then passes through the oil injection hole 25 into the guide ring groove 2 26 to lubricate the hinged end of the connecting rod 9 and the crankshaft 8. Then, the lubricating oil liquid inside the guide ring groove 2 26 passes through the guide channel 3 27 into the oil injection hole 28, and is sprayed into the inside of the piston chamber 3 through the oil injection hole 28. This enables the piston body 4 to drive the lubricating oil liquid inside the piston chamber 3 to lubricate when it reciprocates along the inner wall of the piston chamber 3, effectively improving the lubricating effect of the lubricating oil liquid and reducing the lubrication blind area. At the same time, the oil pressure sensor 32 is configured to monitor in real time the oil pressure of the lubricating oil entering the oil injection hole 28 through the guide channel 3 27. After startup, if the oil pressure in the guide channel 3 27 and the oil injection hole 28 is lower than the set value, the oil pressure sensor 32 will send a signal of too low oil pressure to the oil storage tank 31, causing the oil storage tank 31 to open, wherein the oil pressure sensor 32 is configured as the Omron D6F series. In this way, the lubricating oil in the oil filling valve 30 is sprayed into the oil tank 2 through the oil filling nozzle 29, realizing real-time monitoring of the oil in the oil tank 2, and facilitating the maintenance of the oil pressure stability in the oil tank 2.

[0028] like Figure 1-Figure 4 , Fig. 9 As shown, the inner top of the piston chamber 3 is respectively fixedly connected with an outlet valve 34 and an inlet valve 35, a spiral heat exchange groove 36 is provided inside the chassis 1, the piston chamber 3 is installed inside the spiral heat exchange groove 36, the output end of the spiral heat exchange groove 36 is fixedly connected with a circulation pipe 46, the output end of the circulation pipe 46 is fixedly connected with a circulation pump 37, the input end of the spiral heat exchange groove 36 is fixedly connected with a circulation pipe 1 38, the input end of the circulation pipe 1 38 is fixedly connected with a refrigerator 39, and one end of the chassis 1 is installed with a heat exchange component for connecting the output end of the circulation pump 37 and the input end of the refrigerator 39; The heat exchange assembly includes an intake pipe 40 fixedly connected to the input end of the intake valve 35, the input end of the intake pipe 40 is fixedly connected to a heat exchange pipe 41, the periphery of the heat exchange pipe 41 is fixedly sleeved with a spiral sleeve 42, the input end of the spiral sleeve 42 is fixedly connected to a circulation pipe 2 43, the input end of the circulation pipe 2 43 is fixedly connected to the output end of the circulation pump 37, the output end of the spiral sleeve 42 is fixedly connected to a circulation pipe 3 44, the output end of the circulation pipe 3 44 is fixedly connected to the input end of the refrigerator 39, and the input end of the heat exchange pipe 41 is fixedly connected to an air filter 45; Furthermore, a generator 47 is fixedly connected inside the chassis 1, and an energy storage flywheel 48 is fixedly connected to the output end of the generator 47. The output end of the generator 47 passes through the chassis 1 and is fixedly connected to a driven gear 2 49 meshed with the synchronous belt 20.

[0029] When in use, first, when the operating mechanism is started to drive the driving gear 18 to rotate, the synchronous belt 20 drives the driven gear 2 49 to rotate synchronously, and further causes the driven gear 2 49 to drive the energy storage flywheel 48 to rotate at high speed. In this process, the energy storage flywheel 48 stores mechanical energy. When the system needs additional energy, the rotational kinetic energy of the energy storage flywheel 48 drives the generator 47 to generate electricity through the principle of electromagnetic induction, converting the mechanical energy into electrical energy. The generated electrical energy is transmitted to the circulation pump 37 and the refrigerator 39 through the circuit to power them. The energy storage flywheel 48 adopts the Amber Kinetics - Flywheel Storage flywheel; Then, the circulation pump 37 is started to drive the heat exchange and cooling medium to pass through the spiral heat exchange groove 36, and exchange heat and cool with the inner wall of the piston chamber 3. When the intake valve 35 is started to suck in external air into the piston chamber 3 through the intake pipe 40, the circulation pump 37 drives the heat exchange and cooling medium to be introduced into the interior of the spiral sleeve 42 through the circulation pipe 2 43, and the spiral sleeve 42 uses the internal heat exchange and cooling medium to heat and heat the air that has not entered the intake pipe 40 through the heat exchange pipe 41 to preheat the air entering the piston chamber 3. After preheating, the medium inside the spiral sleeve 42 passes through the circulation pipe 3 44 and enters the interior of the refrigerator 39 for cooling, wherein the refrigerator 39 adopts the Ferrotec TEC1-12706 kit. Finally, the medium cooled by the refrigerator 39 is introduced into the input end of the spiral heat exchange tank 36 through the circulation pipe 1 38 to complete the circulation and cool the inside of the piston chamber 3, thereby facilitating energy recovery and release through the cooperation of the energy storage flywheel 48 and the generator 47, reducing the energy consumption of the system at high load and improving the overall energy efficiency.

[0030] The working principle of an energy-saving vertical air compressor provided by the present invention is as follows: First, the operating mechanism is started, and the power supply motor 17 drives the driving gear 18 to rotate. Then, the driving gear 18 drives the driven gear 19 to rotate synchronously through the synchronous belt 20, further driving the crankshaft 8 to rotate. Then, the crankshaft 8 pulls the piston body 4 to reciprocate along the inner wall of the piston chamber 3 through the connecting rod 9, and the air compression process begins.

[0031] At the same time, the rotation of the crankshaft 8 drives the pumping cylinder 10 to rotate, and the circumferential guide vane ring 11 inside the pumping cylinder 10 sucks the lubricating oil from the arc-shaped oil collecting groove 6 at the bottom of the oil tank 2 through the synergistic effect of centrifugal force and negative pressure zone. The lubricating oil is then evenly distributed to various lubrication points through the guide assembly including the guide channel 21, the guide ring groove 22, the oil filling hole 23, etc., including the hinged end of the crankshaft 8 and the support rod 7, the hinged end between the connecting rod 9 and the crankshaft 8, and the contact end between the piston body 4 and the piston bin 3. The oil pressure sensor 32 monitors the pressure of the lubricating oil in real time to ensure the stability and continuity of the lubrication process. If the oil pressure is lower than the set value, the oil filling valve 30 automatically opens, and the lubricating oil in the oil storage tank 31 is replenished into the oil tank 2 through the oil filling nozzle 29, which reduces the lubrication blind area and reduces friction loss.

[0032] During operation, the synchronous belt 20 also drives the driven gear 2 49 to rotate, further driving the energy storage flywheel 48 to rotate at high speed to store mechanical energy. When the system needs additional energy, the rotational kinetic energy of the energy storage flywheel 48 drives the generator 47 to generate electricity through the principle of electromagnetic induction, converting mechanical energy into electrical energy. Then, the generated electrical energy is transmitted to the circulating pump 37, the refrigerator 39 and other equipment through the circuit to power them.

[0033] The circulation pump 37 drives the heat exchange and cooling medium to pass through the spiral heat exchange groove 36 and exchange heat and cool the inner wall of the piston chamber 3. The air intake pipe 40 sucks the external air into the piston chamber 3 through the air intake valve 35. At the same time, the heat exchange and cooling medium preheats the incoming air through the heat exchange pipe 41 and the spiral sleeve 42. The preheated air participates in the compression process, and the heat exchange and cooling medium enters the refrigerator 39 through the circulation pipe three 44 for cooling. Finally, the cooled medium returns to the input end of the spiral heat exchange groove 36 through the circulation pipe one 38 to complete the cycle.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
