Description

Technical Field

[0001] The present invention is 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 achieve the compression and transportation of gas through precise mechanical movements. It uses the reciprocating movement of a piston in a cylinder or the forced action of a rotating element to enclose the gas in a specific space and increase the gas pressure by gradually reducing the volume, thereby generating a high-pressure gas flow. This device can provide a relatively stable exhaust pressure, and the pressure fluctuation of the output gas is small, which is particularly important for some technological processes with extremely high requirements for pressure stability. For example, in the pneumatic control system of a blowing-type aircraft de-icing device, stable pressure is the key factor to ensure the effective de-icing operation of the device;

[0003] Currently, a gas compressor usually consists of key components such as a cylinder, a piston, and a crankshaft. Generally, the gas compressor is installed on a blowing-type aircraft de-icing device and connected to the heating pipeline system on the device. Its working principle is based on the rotation drive of the crankshaft to make the piston complete a periodic reciprocating movement in the cylinder, thereby realizing the cyclic operation of suction, compression, and exhaust. In a complete working cycle, when the piston moves downward, the volume of the cylinder increases, and the outside gas is inhaled. When the piston moves upward, the volume of the cylinder decreases, and the gas is compressed and discharged into the heating pipeline system in a high-pressure form. This process repeats continuously to form a continuous output of compressed gas;

[0004] However, since the processes of suction, compression, and exhaust are essentially periodic and intermittent, the output compressed gas inevitably shows periodic fluctuations in flow rate and pressure. This kind of fluctuation is likely to cause pressure pulsation phenomena in the conveying pipeline. This pressure pulsation will not only cause additional stress on the pipeline system but also may lead to problems such as fatigue cracking and loose connections of the pipeline, thereby affecting the overall operating efficiency and stability of the compressor.

An air inlet hole 54 located in front of the air outlet hole 55 is formed by a backward depression on the front end surface of the functional block 5. Through the air inlet hole 54, gas is conveyed into the air compression part of the compression cylinder 7.

[0040] An air outlet hole 55 penetrating through the functional block 5 is formed by the outer end face of the functional block 5 recessing inwards. Through the air outlet hole 55, an installation space is provided for the buffer tank 4. An outlet penetrating through the cover plate 52 and communicating with the air compression part of the compression cylinder 7 is formed by the outer end face of the cover plate 52 recessing inwards, and the outlet is communicated and arranged at the inner end of the air outlet hole 55.

Through the first connecting pipe 41, the air pipe 6 and the buffer tank 4 are communicated and arranged;

[0041] The inner cylinder 82 is movably installed in the buffer tank 4. Through the inner cylinder 82, an installation space is provided for components such as the filter plate 821, and the second plug 472 threadedly connected in the inner cylinder 82 is installed at the outer end of the air outlet pipe 47. Through the second plug 472, on the one hand, the disassembly and assembly between the air outlet pipe 47 and the inner cylinder 82 are facilitated, and on the other hand, the inner ends of the air outlet pipe 47 and the inner cylinder 82 are communicated and arranged. The inner end of the air outlet pipe 47 equipped with a valve passes through the buffer tank 4 and the outlet and extends into the air compression part of the compression cylinder 7. Through the air outlet pipe 47, the air compression part of the compression cylinder 7 and the inner cylinder 82 are communicated and arranged. Then, the first plug 471 located on the inner side of the inner cylinder 82 is slidably connected to the outer end of the air outlet pipe 47, and the first plug 471 extending towards the inner side of the buffer tank 4 is threadedly connected in the buffer tank 4. Through the first plug 471, the buffer tank 4 is blocked;

[0042] A first sealing gasket located at the outer end of the air outlet pipe 47 and attached to the outer end face of the cover plate 52 is installed on the inner end of the first plug 471. Through the first sealing gasket, the first plug 471 and the air outlet hole 55 are hermetically connected. A plurality of first annular grooves are formed by the inner wall surface of the first plug 471 recessing outwards. Through the first annular grooves, an installation space is provided for the first sealing ring, and the first sealing ring located at the outer end of the air outlet pipe 47 is assembled on the first annular grooves. Through the first sealing ring, the air outlet pipe 47 and the first plug 471 are hermetically connected;

[0043] The filter cartridge 81 is connected and installed on the outer end of the inner cylinder 82. Through the filter cartridge 81, compressed gas is transported into the buffer tank 4. The piston 8 slidably connected in the buffer tank 4 is arranged on the outer end of the filter cartridge 81. Through the piston 8, an installation carrier is provided for components such as the filter cartridge 81. The lower magnetic ring 43 is installed on the outer end of the piston 8, and then the upper magnetic ring 44 located directly outside the lower magnetic ring 43 is arranged on the inner wall of the buffer tank 4. The upper magnetic ring 44 and the lower magnetic ring 43 are arranged to repel each other. The upper magnetic ring 44 and the lower magnetic ring 43 are used in cooperation to move the piston 8 downward. The auxiliary pipe 401, whose connection position with the buffer tank 4 is between the round rod 45 and the upper magnetic ring 44, is connected and installed on the outer end of the buffer tank 4. Through the auxiliary pipe 401, the space inside the buffer tank 4 above the piston 8 is communicated with the outside;

[0044] The filter plate 821 is threadedly connected inside the inner cylinder 82. Through the filter plate 821, the filter agent is lifted. 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 cartridge 81. Through the filter agent, impurities such as oil and water in the compressed gas are filtered. The filter agent can be activated carbon. Then, the conical cylinder 823, which is arranged with a wider outer part and a narrower inner part and is located directly outside the air outlet pipe 47, is installed on the inner end of the filter plate 821. Through the conical cylinder 823, a processing carrier is provided for the through slots 822. A plurality of through slots 822 extending to the inner wall of the conical cylinder 823 are formed by inward depression on the conical outer end surface of the conical cylinder 823. Through the through slots 822, the compressed gas enters the inner cylinder 82.

[0045] The air storage tank 1 is installed on the blowing-type aircraft deicing equipment in a vertical manner, and the air storage tank 1 is communicated with the heating pipeline system on the equipment. During use, the motor 2 is started first, thereby driving the small pulley 21 to rotate. With the assistance of the belt, the annular pulley 71 rotates, and then a plurality of fan blades 72 and the mounting seat 73 rotate. The rotation of the plurality of fan blades 72 generates an air flow, and the air flow blows towards the compression cylinder 7, thereby performing air cooling treatment on the compression cylinder 7. The rotation of the mounting seat 73 causes the input shaft of the compression cylinder 7 to rotate, and then the piston in the compression cylinder 7 performs an internal and external circulation movement in the air compression part of the compression cylinder 7;

[0046] When the piston moves inward along the air compression part of the compression cylinder 7, it causes the outside air to enter the air compression part of the compression cylinder 7 along the air filter 3, the air inlet hole 54, and the inlet 53. The air filter 3 filters the outside air, and then the piston moves outward along the air compression part of the compression cylinder 7, thereby compressing the outside air that has entered the air compression part of the compression cylinder 7;

[0047] When the compressed gas in the gas compression part of the compression cylinder 7 reaches an appropriate air pressure, with the assistance of the valve, the compressed gas will enter the inner cylinder 82 through the air outlet pipe 47. At this time, the compressed gas will impact the conical cylinder 823, causing the conical cylinder 823 to move outward. As a result, the filter plate 821, the inner cylinder 82, and the filter cylinder 81 will move outward, and then the piston 8 will move outward along the buffer tank 4, buffering 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. Since 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;

[0048] And the conical cylinder 823 will disperse the impacting compressed gas, thereby reducing the impact force generated by the compressed gas and reducing the pulsation formed by the compressed gas due to the air pressure difference. Then the dispersed compressed gas will enter the conical cylinder 823 in a shunt manner through multiple through slots 822. Then the compressed gas in the conical cylinder 823 will penetrate 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 make the compressed gas spread inward in the buffer tank 4, further reducing the pulsation formed by the compressed gas due to the air pressure difference, realizing multi-stage buffering treatment of the compressed gas, effectively reducing the probability of cracking, loosening, etc. of the output pipeline caused by the pulsation generated by intermittent exhaust, and effectively ensuring the operation effect and stability of the compressor;

[0049] 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 piston moves inward again in the gas compression part of the compression cylinder 7, under the action of the repulsive force, components such as the lower magnetic ring 43, the piston 8, the filter cylinder 81, and the inner cylinder 82 will return inward to their original positions, ensuring normal buffering treatment of the generated compressed gas in the subsequent process.

[0050] Embodiment 2: As Figure 4 and Figure 5As shown in the figure, the round rod 45 located inside the upper magnetic ring 44 and the lower magnetic ring 43 is rotatably connected to the inner wall of the buffer tank 4 facing the outer wall. The inner end of the round rod 45 slidably connected to the piston 8 penetrates through the piston 8 and the filter cartridge 81 and extends into the inner cylinder 82. Through the round rod 45, an installation carrier is provided for components such as the first spiral plate 46, 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. A spiral groove 801 is formed on the inner wall of the piston 8 facing outward and located at the outer end of the round rod 45. Through the spiral groove 801, a movement channel is provided for the rolling members. Then, the rolling members rollingly connected in the spiral groove 801 are arranged on the outer end of the round rod 45. The rolling members cooperate with the spiral groove 801 to make the round rod 45 rotate. The rolling members can be universal balls 451.

[0051] During use, first, the motor 2, the small pulley 21, the annular pulley 71, multiple fan blades 72, and the mounting seat 73 are used to make the piston in the compression cylinder 7 of the compression cylinder 7 perform an internal and external circulation movement in the air compression part of the compression cylinder 7. When the piston moves inward along the air compression part of the compression cylinder 7, it will cause the outside air to enter the air compression part of the compression cylinder 7 along the air filter 3, the air inlet hole 54, and the inlet 53. Then, the piston moves outward along the air compression part of the compression cylinder 7, thereby compressing the outside air entering the air compression part of the compression cylinder 7.

[0052] When the compressed air in the air compression part of the compression cylinder 7 reaches the appropriate air pressure, with the assistance of the valve, the compressed air will enter the inner cylinder 82 through the air outlet pipe 47. At this time, the compressed air will collide with the conical cylinder 823, thereby causing the conical cylinder 823 to move outward, and further causing the filter plate 821, the inner cylinder 82, and the filter cartridge 81 to 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, thereby causing the round rod 45 to rotate, and further causing the first spiral plate 46 to rotate, so that the filter agent moves up and down in the space formed by the filter cartridge 81 and the inner cylinder 82, realizing the agitation of the filter agent, effectively reducing the probability of blockage and other problems of the output compressed air due to factors such as caking of the filter agent, effectively ensuring the normal output of the compressed air, and effectively ensuring the operation effect and stability of the compressor.

[0053] Then, through multiple through slots 822, the compressed air enters the conical cylinder 823. Then, the compressed air in the conical cylinder 823 penetrates through the filter plate 821 and enters the filter agent. Then, the filter agent filters and absorbs impurities such as oil and water in the compressed air. Then, the filtered compressed air enters the buffer tank 4 through the filter cartridge 81. Then, the compressed air 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 air is continuously input into the heating pipeline system.

[0059] Then rotate the buffer tank 4, so that the movable plate 422 rotates, and then the clamping columns 425 move along the connection grooves 513 and enter the clamping grooves 512. Then release the buffer tank 4, and under the elastic force of a plurality of elastic members 423, the movable plate 422 moves upward, and then the clamping columns 425 are clamped into the clamping grooves 512, realizing the clamping installation of the buffer tank 4, facilitating the disassembly and assembly of the buffer tank 4, effectively avoiding the probability of shaking and other phenomena due to pulsation and other phenomena of the buffer tank 4, effectively reducing the probability of gas leakage of the buffer tank 4, and effectively ensuring the operation effect and stability of the compressor.

[0060] Example 4: As Figures 11 - 13As 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 arranged in communication with the buffer tank 4. Through the outer cylinder 402, a heat dissipation space is formed at the outer end of the buffer tank 4, and the second spiral plate 405 located outside 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. Through the second spiral plate 405, the space formed between the buffer tank 4 and the outer cylinder 402 is divided into a spiral channel;

[0061] The functional pipe 404 with the other end arranged in communication with the auxiliary pipe 401 is communicatively installed at the upper end of the outer cylinder 402. Through the functional pipe 404, the outer cylinder 402 and the functional pipe 404 are arranged in communication, and a first one-way valve is assembled on the functional pipe 404.

[0062] During use, first, the input shaft of the compression cylinder 7 is rotated by using the motor 2, the small pulley 21, the belt, the annular pulley 71, a plurality of fan blades 72 and the mounting seat 73. Then, the piston in the compression cylinder 7 moves in and out in the air compression part of the compression cylinder 7. When the piston moves inward along the air compression part of the compression cylinder 7, the outside air will enter the air compression part of the compression cylinder 7 along the filter 3, the air inlet hole 54 and the inlet 53. Then, the piston moves outward along the air compression part of the compression cylinder 7, so as to compress the outside air entering the air compression part of the compression cylinder 7;

[0063] When the compressed air in the air compression part of the compression cylinder 7 reaches the appropriate air pressure, with the assistance of the valve, the compressed air will enter the inner cylinder 82 through the air outlet pipe 47. At this time, the compressed air will impact 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;

[0064] And the gas in the space above the piston 8 in the buffer tank 4 is extruded, 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, realizing the secondary heat dissipation treatment of the compressed gas in the buffer tank 4, effectively reducing the probability of damage to components such as the air pipe 6 due to the residual temperature in the compressed gas, and effectively ensuring the operation effect of the compressor;

[0065] Then the gas will enter the filter 3 through the second connecting pipe 403 to realize the recycling of the extruded gas, effectively reducing resource waste. 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 gas pipe 6 for temporary storage, so as to continuously input the compressed gas into the heating pipeline system;

[0066] When the movable plug moves inward again in the air compression part of the compression cylinder 7, under the action of the repulsive force, components such as the lower magnetic ring 43, the piston 8, the filter cartridge 81, and the inner cylinder 82 will return inward to their original positions. At this time, the outside gas will enter the space above the piston 8 in the buffer tank 4 through the auxiliary pipe 401 to ensure the normal buffering treatment of the generated compressed gas in the follow-up.
