Description

Technical Field

[0001] The invention relates to a gas compressor, belonging to the field of compressors. Background Art

[0002] A gas compressor is a power device that converts mechanical energy into gas pressure energy. Its core function is to compress and transport gas through precise mechanical movement. It uses the reciprocating motion of the piston in the cylinder or the forced action of the rotating element to seal the gas in a specific space, and increases the gas pressure by gradually reducing the volume, thereby generating a high-pressure gas flow. This type of equipment can provide relatively stable exhaust pressure, and the pressure fluctuation of the output gas is small, which is particularly important for certain processes that require extremely high pressure stability. For example, in the pneumatic control system of the air-blowing aircraft de-icing equipment, stable pressure is the key factor to ensure that the equipment can effectively perform de-icing operations; At present, gas compressors are usually composed of key components such as cylinders, pistons, and crankshafts. Generally, gas compressors are installed on air-blowing aircraft de-icing equipment, and the gas compressors are connected to the heating pipeline system on the equipment. Its working principle is based on the rotation drive of the crankshaft, so that the piston completes periodic reciprocating motion in the cylinder, thereby realizing the cycle of suction, compression and exhaust. In a complete working cycle, when the piston moves downward, the cylinder volume increases and the external gas is sucked in, and when the piston moves upward, the cylinder volume decreases, the gas is compressed and discharged into the heating pipeline system in the form of high pressure. This process is repeated to form a continuous compressed gas output; However, since the process of suction and compression and exhaust is essentially cyclical and intermittent, the output compressed gas will inevitably show periodic fluctuations in flow rate and pressure. Such fluctuations can easily cause pressure pulsation in the delivery pipeline. Such pressure pulsation will not only cause additional stress burden on the pipeline system, but may also cause problems such as fatigue cracking and loose connections in the pipeline, thereby affecting the overall operating efficiency and stability of the compressor.

The filter plate 821 is used to lift the filter agent, and the filter agent located at the outer end of the filter plate 821 is filled in the space formed by the inner cylinder 82 and the filter cylinder 81. The filter agent is used to filter impurities such as oil and water in the compressed gas. The filter agent can be activated carbon. Then, a conical cylinder 823 that is wide on the outside and narrow on the inside and is located just outside the outlet pipe 47 is installed on the inner end of the filter plate 821. The conical cylinder 823 is used to provide a processing carrier for the through groove 822. The conical outer end surface of the conical cylinder 823 is recessed inward to form a plurality of through grooves 822 extending to the inner wall of the conical cylinder 823. The compressed gas enters the inner cylinder 82 through the through grooves 822.

[0020] The air storage tank 1 is installed on the air-blowing aircraft deicing device in a vertical manner, and the air storage tank 1 is connected to the heating pipe system on the device. When in use, the motor 2 is started first to drive the small pulley 21 to rotate, and with the assistance of the belt, the annular pulley 71 is rotated, and then the multiple blades 72 and the mounting seat 73 are rotated. The rotation of the multiple blades 72 will generate wind flow, and the wind flow blows toward the compression cylinder 7, thereby air-cooling the compression cylinder 7. The rotation of the mounting seat 73 will rotate the input shaft of the compression cylinder 7, and then the movable plug in the compression cylinder 7 performs internal and external circulation movement in the air compression part of the compression cylinder 7. When the movable plug moves inward along the compressed air portion of the compression cylinder 7, the external gas will enter the compressed air portion of the compression cylinder 7 along the filter 3, the air inlet 54 and the inlet 53, and the filter 3 will filter the external gas, and then the movable plug moves outward along the compressed air portion of the compression cylinder 7, thereby compressing the external gas entering the compressed air portion of the compression cylinder 7; When the compressed gas in the compression part of the compression cylinder 7 reaches a suitable pressure, the compressed gas will enter the inner cylinder 82 through the outlet pipe 47 with the help of the valve, and at this time, the compressed gas will collide with the conical cylinder 823, so that the conical cylinder 823 moves outward, and then the filter plate 821, the inner cylinder 82 and the filter cylinder 81 move outward, so that the piston 8 moves outward along the buffer tank 4, which will buffer the impact force. At the same time, the outward movement of the piston 8 will cause the lower magnetic ring 43 to move outward, and then the distance between the lower magnetic ring 43 and the upper magnetic ring 44 will become smaller. Because the lower magnetic ring 43 and the upper magnetic ring 44 are arranged to repel each other, a gradually increasing repulsive force will be generated between the lower magnetic ring 43 and the upper magnetic ring 44. And the conical cylinder 823 will disperse the impacted compressed gas, so as to reduce the impact force of the compressed gas and the pulsation of the compressed gas caused by the pressure difference. Then the dispersed compressed gas will enter the conical cylinder 823 in a diversion manner through multiple through grooves 822, and then the compressed gas in the conical cylinder 823 will pass through the filter plate 821 and enter the filter agent. Then the filter agent will filter and absorb impurities such as oil and water in the compressed gas. Then the filtered compressed gas will enter the buffer tank 4 through the filter cylinder 81, and the compressed gas will spread inward in the buffer tank 4, further reducing the pulsation of the compressed gas caused by the pressure difference, realizing multi-stage buffering treatment of the compressed gas, effectively reducing the probability of cracking and loosening of the output pipeline due to the pulsation caused by the interval exhaust, and effectively ensuring the operation effect and stability of the compressor; Then the compressed gas in the buffer tank 4 will enter the gas storage tank 1 along the first connecting pipe 41 and the air pipe 6 for temporary storage, so that the compressed gas can be continuously input into the heating pipeline system. When the movable plug moves inward again along the compressed gas part of the compression cylinder 7, the lower magnetic ring 43, the piston 8, the filter cylinder 81, the inner cylinder 82 and other components will return to their original positions under the action of the repulsive force, thereby ensuring the subsequent normal buffering treatment of the generated compressed gas.

[0021] Embodiment 2: Figure 4 and Figure 5As shown, the round rod 45 located on the inner side of the upper magnetic ring 44 and the inner side of the lower magnetic ring 43 is rotatably connected to the inner outer wall of the buffer tank 4, and the inner end of the round rod 45 slidably connected to the piston 8 passes through the piston 8 and the filter cartridge 81 and extends into the inner cylinder 82. Through the round rod 45, a mounting carrier is provided for the first spiral plate 46 and other components, and the first spiral plate 46 located in the space formed by the filter cartridge 81 and the inner cylinder 82 is installed on the outer end of the round rod 45. Through the first spiral plate 46, the filter agent is turned over, and a spiral groove 801 located at the outer end of the round rod 45 is formed on the inner wall surface of the piston 8 outwardly. Through the spiral groove 801, a movement channel is provided for the rolling member, and then the rolling member rolling connected in the spiral groove 801 is set on the outer end of the round rod 45. The rolling member and the spiral groove 801 are used in conjunction to rotate the round rod 45. The rolling member can use a universal ball 451.

[0022] When in use, the motor 2, the small pulley 21, the annular pulley 71, the plurality of fan blades 72 and the mounting seat 73 are first used to make the movable plug in the compression cylinder 7 perform an internal and external circulation movement in the compressed air part of the compression cylinder 7. When the movable plug moves inward along the compressed air part of the compression cylinder 7, the external gas will enter the compressed air part of the compression cylinder 7 along the filter 3, the air inlet hole 54 and the inlet 53, and then the movable plug moves outward along the compressed air part of the compression cylinder 7, thereby compressing the external gas entering the compressed air part of the compression cylinder 7. When the compressed gas in the compression part of the compression cylinder 7 reaches a suitable pressure, the compressed gas will enter the inner cylinder 82 through the outlet pipe 47 with the assistance of the valve. At this time, the compressed gas will collide with the conical cylinder 823, so that the conical cylinder 823 moves outward, and then the filter plate 821, the inner cylinder 82 and the filter cylinder 81 move outward, so that the piston 8 moves outward along the buffer tank 4. At this time, the universal ball 451 will move along the spiral groove 801, so that the round rod 45 rotates, and then the first spiral plate 46 rotates, so that the filter medium moves up and down in the space formed by the filter cylinder 81 and the inner cylinder 82, so as to stir the filter medium, effectively reduce the probability of blockage of the output compressed gas due to factors such as agglomeration of the filter medium, effectively ensure that the compressed gas can be output normally, and effectively ensure the operation effect and stability of the compressor; Then, the compressed gas enters the conical cylinder 823 through multiple through grooves 822, and then the compressed gas in the conical cylinder 823 passes through the filter plate 821 and enters the filter agent, and then the filter agent filters and absorbs impurities such as oil and water in the compressed gas, and then the filtered compressed gas passes through the filter cylinder 81 and enters the buffer tank 4, and then the compressed gas in the buffer tank 4 will enter the gas storage tank 1 along the first connecting pipe 41 and the air pipe 6 for temporary storage, so that the compressed gas can be continuously input into the heating pipeline system.

[0025] Embodiment 4: Figure 11-13 As shown, the outer cylinder 402 located on the outer side of the upper plate 42 is installed on the annular outer end of the buffer tank 4, and the first connecting pipe 41 passes through the outer cylinder 402 and is connected to the buffer tank 4. A heat dissipation space is formed at the outer end of the buffer tank 4 through the outer cylinder 402, and a second spiral plate 405 located on the outer side of the first connecting pipe 41 is installed between the outer end of the buffer tank 4 and the inner wall of the outer cylinder 402.

[0026] When in use, the motor 2, the small pulley 21, the belt, the annular pulley 71, the plurality of fan blades 72 and the mounting seat 73 are first used to rotate the input shaft of the compression cylinder 7, and then the movable plug in the compression cylinder 7 performs an internal and external circulation movement in the compressed air part of the compression cylinder 7. When the movable plug moves inward along the compressed air part of the compression cylinder 7, the external gas will enter the compressed air part of the compression cylinder 7 along the filter 3, the air inlet 54 and the inlet 53, and then the movable plug moves outward along the compressed air part of the compression cylinder 7, thereby compressing the external gas entering the compressed air part of the compression cylinder 7; When the compressed gas in the compression part of the compression cylinder 7 reaches a suitable pressure, the compressed gas will enter the inner cylinder 82 through the outlet pipe 47 with the help of the valve, and at this time, the compressed gas will collide with the conical cylinder 823, so that the conical cylinder 823, the filter plate 821, the inner cylinder 82, the filter cylinder 81 and the piston 8 move outward, and a gradually increasing repulsive force will be generated between the lower magnetic ring 43 and the upper magnetic ring 44; The gas in the space above the piston 8 in the buffer tank 4 is squeezed, so that the gas enters the spiral pipeline formed by the outer cylinder 402, the buffer tank 4 and the second spiral plate 405 along the auxiliary pipe 401 and the functional pipe 404, and the gas flows in the spiral pipeline and exchanges heat with the residual temperature in the compressed gas in the buffer tank 4, so as to achieve secondary heat dissipation treatment of the compressed gas in the buffer tank 4, effectively reduce the probability of damage to components such as the air pipe 6 due to the residual temperature in the compressed gas, and effectively ensure the operation effect of the compressor; Then the gas will enter the filter 3 through the second connecting pipe 403, so as to recycle the squeezed gas and effectively reduce the waste of resources. At the same time, the compressed gas after heat dissipation in the buffer tank 4 will enter the gas storage tank 1 along the first connecting pipe 41 and the air pipe 6 for temporary storage, so that the compressed gas can be continuously input into the heating pipeline system. When the movable plug moves inward again along the compressed air part of the compression cylinder 7, the repulsive force will cause the lower magnetic ring 43, the piston 8, the filter cylinder 81, the inner cylinder 82 and other components to return to their original positions. At this time, the external gas will enter the space above the piston 8 in the buffer tank 4 through the auxiliary pipe 401, ensuring the subsequent normal buffering treatment of the generated compressed gas.
