Description

Technical Field

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

[0002] An air compressor is a device that converts mechanical energy into gas pressure energy. It compresses air to increase the air pressure, thereby meeting various industrial, commercial or life needs. For example, in an auto repair shop, an air compressor can be used to provide a power source for pneumatic tools (such as pneumatic wrenches, pneumatic screwdrivers, etc.); on a construction site, it can be used to drive tools such as pneumatic nail guns.

[0003] For example, an energy-saving air compressor disclosed in the authorization announcement number CN220726509U includes a frame body, an air storage tank body fixedly mounted on the top of the frame body, a compressor body fixedly mounted on the top of the air storage tank body, a cooling device fixedly mounted on one side of the air storage tank body, a waste heat utilization device fixedly mounted on one side of the compressor body, and a power generation device fixedly mounted on one side of the waste heat utilization device. After adopting the above technical scheme, the beneficial effects of the utility model are as follows: through the waste heat utilization device and the power generation device, the excess power of the motor in the air extraction stage and the excess heat generated when the compressor is working are fully utilized to generate electricity, and the generated electricity can be used to power the motor, thereby greatly reducing energy consumption.

[0004] Although the above patent makes full use of the excess power of the motor in the exhaust stage and the excess heat generated by the compressor during operation to generate electricity, greatly reducing energy consumption. However, during the operation of the compressor, the cooling water is constantly circulated and absorbs heat, so the sealed nitrogen is also constantly expanding due to heat. Therefore, when the power generation cam rotates and presses down the push block, it will be affected by the resistance generated by the expanded nitrogen, which may invisibly increase the energy consumption of the compression motor;

[0005] Moreover, the high-temperature nitrogen may conduct heat to the generator box through the push block, and the high-temperature nitrogen is continuously heated, and the heat cannot be effectively volatilized. At the same time, the high-temperature return water directly enters the cooler, and the heat in the high-temperature return water is not recovered and utilized by the cooler, resulting in a certain amount of energy waste. Summary of the invention

[0006] The object of the present invention is to provide an energy-saving gas compressor to solve the problems raised in the above background technology.

[0017] Furthermore, the recovery mechanism includes a water tank, which is opened at the middle upper end of the box body, and a second installation tank is arranged at the upper right end of the inner side of the box body. The end of the return pipe away from the cooling shell passes through the second installation tank and is connected to the water tank.

There is an air intake pipe 19, and the right side of the upper end of the piston cylinder 17 is connected to an exhaust pipe 20 through a one-way valve. The other end of the exhaust pipe 20 is connected to the air inlet end of the air storage tank 2. The end of the air storage tank 2 away from the exhaust pipe 20 is provided with an air outlet pipe. A second heat dissipation mechanism is provided between the compression mechanism and the shell 3 and the box body 4. The second heat dissipation mechanism includes a cooling shell 21. The cooling shell 21 is annularly arranged on the outside of the middle part of the piston cylinder 17. The lower end of one end of the cooling shell 21 is connected to the hot water pipe 15. A return pipe 22 is provided on the upper end of the adjacent side of the cooling shell 21 close to the hot water pipe 15. The other end of the return pipe 22 is connected to the recovery mechanism.

[0035] In this embodiment, since the large pulley 11 is meshed with the small pulley 8 through a toothed belt for transmission, the large pulley 11 can drive the small pulley 8 to rotate synchronously through the toothed belt, thereby driving the heat dissipation fan blades 9 to rotate. When the heat dissipation fan blades 9 rotate, they drive the air to flow and blow toward the heat dissipation fins 16 in the middle of the hot water pipe 15.

[0036] like Figure 3 , Figure 6 and Figure 7 As shown, a recovery mechanism is provided inside the box body 4, and the recovery mechanism includes a water tank 23, which is opened at the middle upper end of the box body 4, and a second installation tank 24 is provided at the upper right end of the box body 4. The end of the return pipe 22 away from the cooling shell 21 passes through the second installation tank 24 and is connected to the water tank 23. The second installation tank 24 is located outside the return pipe 22 and a thermoelectric power generation module 25 is provided. The box body 4 is located at the middle of the bottom end of the water tank 23 and a ceramic sealing plate 26 is provided. The ceramic sealing plate 26 A Peltier cooling sheet array 27 is provided on the lower end surface, and the Peltier cooling sheet array 27 is electrically connected to the thermoelectric power generation module 25. A heat dissipation duct 28 is also provided at the lower middle part of the box body 4. A worm 29 is laterally provided at the upper middle end of the heat dissipation duct 28. The two ends of the worm 29 are respectively connected to the large pulley 11 and the centrifugal pump 13 through a transmission shaft 30. A fan assembly 31 is further provided at the lower inner part of the heat dissipation duct 28, and the fan assembly 31 is meshed with the worm 29 through a worm gear 32.

[0037] In this embodiment, the cooling water absorbs heat and enters the return pipe 22. The thermoelectric power generation module 25 converts the thermal energy of the high-temperature return water in the return pipe 22 into electrical energy. The generated electrical energy is supplied to the Peltier cooling plate array 27. The Peltier cooling plate array 27 starts to work after receiving the provided electrical energy. The ceramic sealing plate 26 absorbs the heat of the high-temperature return water in the water tank 23 to reduce its temperature. In this way, the heat of the high-temperature return water can be directly recycled and utilized, so that it drives the Peltier cooling plate array 27 to cool the high-temperature return water again, thereby achieving the purpose of energy saving.

[0038] Working principle: When working, the motor 10 is started, and the motor 10 drives the piston body 18 to move up and down inside the piston cylinder 17, compressing the air entering from the intake pipe 19 into the exhaust pipe 20, and then storing it in the gas storage tank 2 through the exhaust pipe 20; when the motor 10 is started, it drives the large pulley 11 and the transmission shaft 30 to rotate. Since the transmission shaft 30 is connected to the driving end of the centrifugal pump 13, the driving end of the centrifugal pump 13 is driven to rotate when the transmission shaft 30 rotates, and controls the impeller inside it to rotate at a high speed to extract the cooling water inside the water tank 23, and then send it into the outer shell 3 through the cold water pipe 14. The cooling water absorbs the heat of the gas inside the gas storage tank 2 and enters the hot water pipe 15. Since the large pulley 11 is meshed with the small pulley 8 through the toothed belt, the large pulley 11 can drive the small pulley 8 to rotate synchronously through the toothed belt, thereby driving the heat dissipation fan blades 9 to rotate. When the heat dissipation fan blades 9 rotate, they drive the air to flow and blow to the middle of the hot water pipe 15. The cooling fins 16 of the heat dissipation device 10 absorb part of the heat from the cooling water output from the housing 3. At this time, the cooling water is heat-dissipated by the flowing air and enters the cooling shell 21, and then the piston cylinder 17 and the piston body 18 are heat-dissipated. After absorbing the heat, the cooling water enters the return pipe 22, and the thermoelectric power generation module 25 converts the heat energy of the high-temperature return water in the return pipe 22 into electrical energy. The generated electrical energy is supplied to the Peltier cooling plate array 27. The Peltier cooling plate array 27 starts to work after receiving the provided electrical energy. The ceramic sealing plate 26 absorbs the heat of the high-temperature return water in the water tank 23 to reduce its temperature. When the transmission shaft 30 rotates, it also drives the worm 29 to rotate. When the worm 29 rotates, it drives the worm wheel 32 to rotate. Since the worm wheel 32 is connected to the fan blade component inside the fan assembly 31 through the rotating shaft, the worm wheel 32 drives the fan blade component to rotate, and the heat generated by the hot end of the Peltier cooling plate array 27 is discharged from the heat dissipation duct 28.
