Description

Technical Field

[0001] The invention relates to the technical field of air compression, and in particular to a novel spiral multiplication air compression system. Background Art

[0002] With the continuous development of modern industry, the requirements for compressed air quality are becoming higher and higher, and are becoming more diversified. At present, compressed air has become an indispensable power in human production and life, and is widely used in various industrial fields.

[0003] At present, air compression mainly relies on piston compressors, which are compressors that rely on the reciprocating motion of pistons to pressurize and transport gas, also known as "reciprocating piston compressors" or "reciprocating compressors". For example, CN201621261865.4 discloses a crankshaft of a piston compressor and a piston compressor (published on 2017-11-27); CN201811068778.0 discloses a cylinder seat assembly of a piston compressor, a piston compressor and a refrigeration system (published on 2018-11-11); CN201510240999.1 discloses a crankshaft for a piston compressor and a piston compressor having the same (published on 2015-08-05); its working principle is as follows:

[0004] S1. When the motor is started, it drives the crankshaft to rotate, and through the transmission of the connecting rod, the piston reciprocates in the cylinder.

[0005] S2. When the piston starts to move from the cylinder head, the working volume in the cylinder gradually increases. At this time, the gas pushes open the intake valve along the intake pipe and enters the cylinder until the working volume becomes the maximum and the intake valve closes.

[0006] S3. When the piston moves in the reverse direction, the working volume in the cylinder decreases and the gas pressure increases. When the pressure in the cylinder reaches and is slightly higher than the exhaust pressure, the exhaust valve opens and the gas is discharged from the cylinder until the piston moves to the limit position and the exhaust valve closes.

[0007] S4. When the piston moves in the opposite direction again, the above process repeats. In short, the crankshaft rotates one circle, the piston reciprocates once, and the process of intake, compression, and exhaust is realized in the cylinder successively, that is, a working cycle is completed.

[0008] During the compression process of a piston compressor, the gas is discharged intermittently, that is, each time the piston moves in the opposite direction to the limit position, the exhaust valve opens and the gas is discharged. This discontinuous exhaust method causes the gas pressure in the compressor exhaust pipe to fluctuate. As the piston reciprocates in the cylinder, the working volume increases and decreases periodically, causing the gas volume and pressure to change accordingly. This change in volume and pressure is intermittent, causing fluctuations in gas pressure. At the same time, there is an inherent vibration frequency in the exhaust pipe and intermediate pipe of the piston compressor. When the frequency of the exhaust pressure fluctuation is close to or the same as the inherent vibration frequency of the pipe, resonance will occur, further exacerbating the pressure fluctuation.

[0009] In turn, this intermittent pressure fluctuation will increase the power required by the compressor, because the compressor needs to consume more energy to overcome the pressure fluctuations in the pipeline. Pressure fluctuations may cause abnormal swings in the pipeline, causing damage to components connected to the pipeline, pipeline equipment, and buildings. Pressure fluctuations will make the operation of the compressor unstable, affecting the quality and output of compressed gas.

[0010] Therefore, a new type of spiral multiplication air compression system is proposed. Summary of the invention

[0011] In view of this, the embodiment of the present invention hopes to provide a new type of spiral multiplication air compression system to solve or alleviate the technical problem existing in the prior art, that is, how to avoid intermittent pressure fluctuations, and at least provide a beneficial option for this; the technical solution of the present invention is implemented as follows:

[0012] A novel spiral multiplication air compression system includes a conical compression mechanism 2. The compression mechanism is designed with precise spiral grooves, which gradually narrow as the cone shrinks. The rotating member is installed inside the compression mechanism and is connected to the rotary actuator 5. When the rotary actuator 5 is started, it drives the rotating member to perform continuous rotational motion inside the compression mechanism 2. Air is sucked in through the inlet of the compression mechanism and is enclosed in the gradually shrinking spiral groove as the rotating member rotates. As the rotating member continues to rotate, the air enclosed in the spiral groove is continuously compressed and moves along the spiral groove toward the air outlet. Finally, the high-pressure air is discharged from the air outlet for subsequent use.

[0013] In one embodiment, the compression mechanism 2 is designed as a closed, tapered casing tube 201. The large end of the casing tube serves as an air inlet 203 for inhaling external air, while the small end serves as an air outlet 204 for discharging compressed high-pressure air. Inside the casing tube 201, the rotating member is precisely installed and forms a rotational fit with the casing tube. The design of this rotating member is very critical. Its shape is completely consistent with the taper of the casing tube 201, ensuring that it can fit tightly with the inner wall of the casing tube during rotation, thereby forming a series of gradually shrinking spiral grooves. When the rotating member rotates in the casing tube, it drives the inhaled air to move in the spiral groove, and is gradually compressed as the groove shrinks.

[0014] In one embodiment, the rotating member is designed as a spiral member 203 having a spiral continuous blade structure. The spiral member 203 is installed inside the casing tube 201 and forms a series of spiral grooves with the tube wall of the casing tube. These spiral grooves extend along the conical direction of the casing tube, gradually shrinking from the air inlet 203 until the air outlet 204 reaches the minimum volume. When the spiral member 203 starts to rotate under the drive of the rotary actuator 5, it drives the inhaled air to move along the conical direction in the spiral groove. As the volume of the spiral groove gradually decreases, the air is continuously compressed during the movement and is finally discharged from the air outlet 204 in a high-pressure state.

[0015] In one embodiment, the air inlet 203 is connected to the air inlet device 3 through a pipe or a connector. The air inlet device 3 is responsible for introducing external air into the compression mechanism 2 to provide a continuous supply of raw materials for the air compression process. At the same time, the air outlet 204 is also connected to the storage device 4 through a pipe or a connector. The storage device 4 is used to receive and store compressed high-pressure air for subsequent use or distribution. In addition, a control system 6 is also connected to the part of the casing tube 201 near the air outlet 204. The control system 6 is used to monitor and adjust the air compression process to ensure that the compression mechanism can work according to predetermined parameters and requirements. By adjusting the settings of the control system 6, precise control of the air compression process can be achieved, thereby obtaining the required compressed air quality and pressure.

[0016] In one embodiment, the control system 6 is specifically designed as a pressure relief valve, a control valve, an air volume regulating valve, a stop valve, a gate valve, a throttle valve or a pressure reducing valve in any combination. These valves or regulating devices are installed at the part of the casing pipe 201 close to the air outlet 204, or are connected to other key components of the compression mechanism 2 to achieve accurate control and regulation of the air compression process.

[0017] In one embodiment, the compression mechanism 2 is fixed on the frame 1, and the frame 1 is fixed in the external environment.

[0018] Implementation method: The compression mechanism 2 is fixedly mounted on the frame 1, and the frame 1 is firmly fixed in the external environment, such as the ground, wall or other supporting structures. This installation method ensures the stability and reliability of the compression mechanism 2 during operation, and avoids performance degradation or damage caused by vibration or movement. The frame 1, as a supporting platform for the compression mechanism 2, not only provides a stable installation foundation, but also facilitates the maintenance and overhaul of the compression mechanism. At the same time, by fixing the frame 1 in the external environment, the entire air compression system can be made more compact and neat, and easy to connect with other equipment or systems in the external environment.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Efficient and stable compression performance: The new spiral design allows the air to maintain continuous and stable flow during the compression process, avoiding intermittent pressure fluctuations caused by mechanical structure limitations of traditional compressors, thereby improving compression efficiency and stability. The continuous spiral compression process reduces energy loss and heat generation, making the compressor more energy efficient and less expensive to operate.

[0021] 2. Easy maintenance and long service life: The spiral compressor has relatively few parts and the contact area between moving parts is small, which reduces the possibility of wear and failure, thereby extending the service life of the compressor. At the same time, the compact structure design also facilitates the maintenance and overhaul of the compressor, reducing maintenance costs and difficulty. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below;

[0028] Example: In the prior art, traditional air compression systems often use reciprocating or rotary compressors. Due to the limitations of the mechanical structure, these compressors are prone to intermittent pressure fluctuations during operation. Such fluctuations not only affect the quality and stability of compressed air, but may also cause impact and damage to downstream equipment. For this purpose, please refer to Figure 1-3 , this embodiment will provide relevant technical solutions to solve the above technical problems: a new type of spiral multiplication air compression system, including a compression mechanism 2;

[0029] The compression mechanism 2 is conical and has a rotating part inside. When the rotating part is driven to rotate by the rotary actuator 5, the inhaled air is enclosed in the compression mechanism 2 which gradually shrinks, and moves along with the rotation direction of the rotating part, thereby achieving air compression.

[0030] As the air is enclosed in the gradually shrinking spiral groove and moves toward the outlet, the air is compressed due to the gradual reduction in the volume of the spiral groove. This process is continuous because the screw is constantly rotating. Compared with piston compressors, this continuous compression process avoids intermittent pressure fluctuations and provides more stable compressed air.

[0031] Specifically: The working principle of the spiral multiplier air compression system is based on the volume change of the spiral groove and the continuous movement of the rotating part. When the rotating part rotates, it drives the air to move in the spiral groove. Since the volume of the spiral groove gradually decreases as the cone shrinks, the air is continuously compressed during the movement. This compression process is continuous because the rotating part is constantly rotating, thus avoiding intermittent pressure fluctuations like piston compressors. The design of the spiral groove allows the air to maintain a stable flow state during the compression process, thereby achieving more efficient compression and more stable output pressure.

[0032] It can be understood that in the technical solution provided in this embodiment: the new spiral multiplying air compression system has significant functional advantages. First, its continuous compression process avoids intermittent pressure fluctuations and provides a more stable and reliable compressed air output. This is crucial for industrial applications that require stable air pressure. Secondly, since the compression process is continuous, the compression efficiency of the present system is higher and the required compression ratio can be achieved in a shorter time. In addition, the structure of the present system is relatively simple, the maintenance cost is low, and it is easy to realize automatic control. These characteristics make the new spiral multiplying air compression system have broad application prospects in industrial production, medical equipment, aerospace and other fields. Especially in situations where high requirements are placed on the quality and stability of compressed air, the present system can perform excellent performance.

[0033] In this solution, all electrical components of the device as a whole rely on AC power for energy supply; specifically, the electrical components of the device as a whole are conventionally electrically connected to the AC power output port through devices such as relays, transformers and button panels to meet the energy supply requirements of all electrical components of the device.

[0034] Specifically, a controller is also provided on the outside of the device, which is used to connect and control all electrical components of the device as a whole to be driven according to a pre-set program as a preset value and a driving mode; it should be pointed out that the above-mentioned driving mode corresponds to the corresponding start and stop time intervals, speed, power and other output parameters between the relevant electrical components mentioned below, that is, it meets the requirements of the relevant electrical components described below to drive the relevant mechanical devices to operate according to the functions described therein.

[0035] Preferably, the controller is a PLC controller, which completes the above control requirements through conventional PLC control modes such as ladder diagrams, sequential function diagrams, function block diagrams, instruction tables or structured texts; it should be pointed out that the output parameters such as the start and stop time intervals, speed, power, etc. of the electrical components or other power components driven by its programming are non-limiting; specifically, the relevant drive control is adjusted according to actual usage requirements.

[0036] In the technical solution provided in this embodiment, please refer to Figures 2-3 The compression mechanism 2 comprises a closed and tapered casing tube 201, wherein the large opening of the casing tube 201 is an air inlet 203 and the small opening is an air outlet 204; a rotating member is rotatably matched inside the casing tube 201. The rotating member has the same taper as the casing tube 201.

[0037] Specifically: Based on spiral compression and volume change of the tapered space. Since the rotating part has the same taper as the casing tube, when the rotating part rotates, it forms a continuously changing spiral groove in the casing tube. The volume of this spiral groove gradually decreases from the air inlet until it reaches the minimum at the air outlet. After being inhaled, the air is enclosed in this gradually shrinking spiral groove and is continuously compressed as the rotating part rotates. Since this process is continuous, intermittent pressure fluctuations can be avoided and more stable air compression can be achieved.

[0038] It is understandable that in the technical solution provided in this embodiment: through the design of the conical casing tube and the rotating part matched therewith, a continuous and stable air compression process is achieved, and the compression efficiency and air quality are improved. Secondly, since the taper of the rotating part is the same as that of the casing tube, the continuity and sealing of the spiral groove are ensured, and gas leakage and energy loss in the compression process are avoided. In addition, this design also makes the structure of the compression mechanism more compact, simple, and easy to maintain and operate. These characteristics make the system have broad application prospects in industrial fields that require stable and efficient air compression, such as manufacturing, aerospace, medical equipment and other fields.

[0039] In the technical solution provided in this embodiment, please refer to Figures 2-3 : The rotating member is a spiral member 203 having a spiral continuous fan blade structure; a spiral groove is formed between the spiral member 203 and the tube wall of the casing tube 201; according to the conical direction, when the spiral member 203 rotates, the volume of the spiral groove gradually decreases, thereby achieving air compression.

[0040] Preferably, the rotary actuator 5 is a servo motor, and the output shaft of the servo motor is fixedly connected to the shaft of the screw member 203 to drive the rotation.

[0041] Preferably, the helix angle of the spiral element 203 (the plane section angle of the spiral tooth angle, ie, the axial side section angle thereof) is 45°.

[0042] Specifically, continuous spiral grooves are formed between the spiral continuous blade structure of the spiral element 203 and the tube wall of the casing tube 201, and the volume of these spiral grooves gradually decreases as the cone direction extends. When the spiral element rotates, it drives the air to move in the spiral groove, and the air is gradually compressed due to the reduction in the volume of the groove. This process is continuous because the spiral element is constantly rotating, thereby avoiding intermittent pressure fluctuations. At the same time, the design of the spiral groove enables the air to maintain a stable flow state during the compression process, thereby improving the compression efficiency and air quality.

[0043] It is understandable that in the technical solution provided in this embodiment: the spiral member 203 with a spiral continuous fan blade structure plays a key role in the new spiral multiplication air compression system. It not only realizes the continuous compression process of air, but also improves the compression efficiency and air quality. As the volume of the spiral groove gradually decreases, the air is gradually compressed during the movement, thereby obtaining a higher compression ratio and a more stable output pressure. In addition, this design also makes the structure of the compression mechanism more compact, simple, easy to maintain and operate. These characteristics make the system have a wide range of application prospects in industrial fields that require efficient and stable air compression, such as pneumatic tools in the manufacturing industry, air pressure systems in the aerospace field, gas supply in medical equipment, etc. At the same time, since the system avoids intermittent pressure fluctuations, it is also suitable for occasions with high requirements for compressed air stability.

[0044] In the technical solution provided in this embodiment, please refer to Figures 2-3 : The air inlet 203 is connected to the air inlet device 3 through a pipeline or a connector. The air inlet device 3 is responsible for introducing external air into the compression mechanism 2 to provide a continuous supply of raw materials for the air compression process. At the same time, the air outlet 204 is also connected to the storage device 4 through a pipeline or a connector. The storage device 4 is used to receive and store compressed high-pressure air for subsequent use or distribution. In addition, a control system 6 is also connected to the part of the casing tube 201 near the air outlet 204. This control system 6 is used to monitor and adjust the air compression process to ensure that the compression mechanism can work according to predetermined parameters and requirements. By adjusting the settings of the control system 6, precise control of the air compression process can be achieved, thereby obtaining the required compressed air quality and pressure.

[0045] Specifically: the three processes of air intake, compression and storage are organically combined, and precise control is achieved through the control system. The air intake device 3 is responsible for providing a stable air source for the compression mechanism to ensure that the compression process can continue. The coordinated use of the casing tube 201 and the spiral member 203 realizes the continuous compression process of air. The storage device 4 is used to receive and store compressed high-pressure air for subsequent use. The introduction of the control system 6 makes the entire compression process more intelligent and controllable. By monitoring the working state of the compression mechanism and adjusting relevant parameters, the control system can ensure that the compression process always remains in the best state, thereby obtaining high-quality compressed air.

[0046] It can be understood that in the technical solution provided in this embodiment: through the coordinated use of the air intake device and the storage device, the continuous compression and storage process of air is realized, and the compression efficiency and air quality are improved. Secondly, the introduction of the control system makes the entire compression process more intelligent and controllable, and the compression parameters and working state can be adjusted according to actual needs, so as to obtain the required compressed air quality and pressure.

[0047] In the technical solution provided in this embodiment, please refer to Figures 2-3 The control system 6 is specifically designed as a pressure relief valve, a control valve, an air volume regulating valve, a stop valve, a gate valve, a throttle valve or a pressure reducing valve in any combination. These valves or regulating devices are installed in the part of the casing pipe 201 close to the air outlet 204, or are connected to other key components of the compression mechanism 2 to achieve precise control and regulation of the air compression process. It includes:

[0048] (1) Pressure relief valve: It is used to automatically open when the pressure inside the compression mechanism is too high to release part of the pressure to protect the compression mechanism from damage.

[0049] (2) Control valve: used to control the working state of the compression mechanism, such as starting, stopping or adjusting the compression ratio.

[0050] (3) Air volume regulating valve: used to adjust the air flow entering the compression mechanism, thereby controlling the output of compressed air.

[0051] (4) Stop valve: used to completely close or open the air inlet or outlet channel of the compression mechanism to achieve air cutoff or circulation.

[0052] (5) Gate valve: Similar to a stop valve, but usually has greater flow capacity and tighter closing performance.

[0053] (6) Throttle valve: used to adjust the flow rate and pressure of air inside the compression mechanism to achieve precise compression control.

[0054] (7) Pressure reducing valve: used to reduce the air pressure at the outlet of the compression mechanism to meet the requirements of compressed air pressure in different applications.

[0055] Through the combined use of these valves or regulating devices, all-round control of the air compression process can be achieved to ensure that the compression mechanism can work according to the predetermined parameters and requirements.

[0056] Specifically: Different types of valves or regulating devices are used to accurately control the pressure, flow rate and flow rate of the air inside the compression mechanism. By adjusting the opening or position of these valves or regulating devices, the working state of the compression mechanism can be changed, thereby achieving accurate regulation of the air compression process. This control method has the advantages of fast response speed and high control accuracy, and can meet the requirements of compressed air quality and pressure in different applications.

[0057] It is understandable that in the technical solution provided in this embodiment: the control system 6 composed of valves or regulating devices such as pressure relief valves, control valves, air volume regulating valves, stop valves, gate valves, throttle valves or pressure reducing valves provides a powerful control function for the new spiral multiplier air compression system. This control system can not only realize the continuous compression and stable output of air, but also accurately adjust the quality, pressure and flow of compressed air according to actual needs. This makes the system have a wide range of application prospects in industrial fields that require efficient, stable and controllable air compression, such as pneumatic tools in manufacturing, automation equipment, air pressure systems in the aerospace field, gas supply in medical equipment, and air compression energy storage in the energy field. At the same time, because the system has a high degree of controllability and flexibility, it is also suitable for special occasions with high requirements for compressed air quality and pressure.

[0058] In the technical solution provided in this embodiment, please refer to Figures 2-3 :The compression mechanism 2 is fixedly mounted on the frame 1, and the frame 1 is firmly fixed in the external environment, such as the ground, wall or other supporting structures. This installation method ensures the stability and reliability of the compression mechanism 2 during operation, and avoids performance degradation or damage caused by vibration or movement. The frame 1, as a supporting platform for the compression mechanism 2, not only provides a stable installation foundation, but also facilitates the maintenance and overhaul of the compression mechanism. At the same time, by fixing the frame 1 in the external environment, the entire air compression system can be made more compact and neat, and easy to connect with other equipment or systems in the external environment.

[0059] In practical applications, this implementation can make the air compression system more adaptable to different working environments and needs. For example, in the manufacturing industry, the air compression system can be installed next to the production line to provide a stable compressed air source for pneumatic tools; in the aerospace field, the air compression system can be installed in the test equipment to provide accurate compressed air for the air pressure system; in medical equipment, the air compression system can be installed in the operating room or treatment room to provide a reliable gas supply for medical equipment.

[0060] In summary, in view of the related problems in the traditional technology, this specific implementation method is based on the above-mentioned new type of spiral multiplication air compression system, and adopts the following technical means or features to achieve the solution:

[0061] The novel system uses a spiral member 203 with a spiral continuous blade structure, which forms a continuous spiral groove when rotating in the casing tube 201. The volume of these spiral grooves gradually decreases as the cone direction extends, realizing a continuous compression process of the air. Due to the continuity of the spiral grooves and the gradually decreasing volume design, the air can maintain a stable flow state during the compression process, avoiding intermittent pressure fluctuations.

[0062] The spiral member 203 is stably driven by the rotary actuator 5 to ensure the stability of the rotation speed and the rotation direction. The stable rotation drive makes the compression process of the air in the spiral groove more stable, further reducing the possibility of pressure fluctuations.

[0063] The system is equipped with a control system 6, which can be a combination of multiple valves such as a pressure relief valve, a control valve, and an air volume regulating valve. The control system can monitor the working status of the compression mechanism in real time and adjust relevant parameters (such as air intake, compression ratio, rotation speed, etc.) as needed to ensure the stability and continuity of the compression process. When pressure fluctuations are detected, the control system can respond quickly and adjust the valve opening or rotation speed to smooth the fluctuations and maintain a stable output of compressed air.

[0064] The compression mechanism 2 is fixed on the frame 1, and the frame 1 is fixed in the external environment, which ensures the structural compactness and rigidity of the entire system. This design reduces pressure fluctuations caused by vibration or external interference and improves the stability and reliability of the system.

[0065] The new spiral multiplier air compression system achieves effective suppression of intermittent pressure fluctuations through a continuous spiral compression process, stable rotary drive, precise control system adjustment, and compact structural design. The continuous spiral compression process ensures that the air can flow smoothly and be gradually compressed during the compression process, avoiding intermittent pressure fluctuations caused by mechanical structural limitations. The stable rotary drive provides a constant power source for the rotation of the spiral, making the compression process more stable and controllable. Precise control system adjustment can monitor and adjust key parameters in the compression process in real time to ensure stable output of compressed air and controllable quality.

[0066] The above-mentioned embodiments only express the implementation methods of the relevant practical applications of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
