[0016] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] As Figure 1 shown, the present application provides an integrated screw machine, including: an air storage tank 1, a support plate 2, a compression component 4, an oil inlet component 5, a variable frequency speed regulation module 6 and a control module.

[0018] Specifically, a fixing member 3 is provided at the bottom of the support plate 2 and is installed on the top of the air storage tank 1 through the fixing member 3. The compression assembly 4 is installed on the support plate 2 and includes a driving motor 41 and a compression rotor 42. The driving motor 41 and the compression rotor 42 are connected by a coupling and are used to drive the compression rotor 42 to compress the input air. The compression assembly 4 is communicated with the air storage tank 1. The oil inlet assembly 5 is installed on the support plate 2 and is connected to the compression assembly 4 through a pipeline. The oil inlet assembly 5 can input oil for cooling into the compression assembly 4. The variable frequency speed regulation assembly is installed on the compression assembly 4 and is used to realize the variable frequency regulation of the driving motor 41. The control module is installed on the compression assembly 4 and is integrally arranged with the variable frequency speed regulation module 6 and is used to set parameters and control the operation of the variable frequency speed regulation module 6.

[0019] The above integrated screw machine significantly optimizes the structural design. Compared with the traditional split layout, it effectively reduces the installation floor area and wiring complexity, and is especially suitable for usage scenarios with high space requirements. At the same time, due to the physical integration of the control module and the frequency conversion module, the system runs more stably, has a faster response speed, and enhanced anti-interference ability, thereby improving the operation reliability and control accuracy of the whole machine. In addition, this structure also makes the later maintenance more convenient, reduces the maintenance workload and labor cost, and improves the equipment operation and maintenance efficiency.

[0020] More specifically, the oil inlet assembly 5 includes a fan 51 and an oil storage member 52. The fan 51 is at least partially arranged on the support plate 2. The oil storage member 52 is connected to the fan 51 through a pipeline, and the oil storage member 52 is internally communicated with the compression assembly 4 through a pipeline. Through the above settings, the rise of the oil temperature can be effectively controlled, and the operation risk caused by the over-high temperature of the compression assembly 4 can be reduced. At the same time, the combination of the fan 51 and the oil storage member 52 improves the heat dissipation efficiency of the lubrication system and the oil circulation capacity, which is beneficial to extending the service life of the oil product and enhancing the overall service life of the compressor. The overall design layout is compact, the lubrication path is clear, and the assembly consistency and later maintenance convenience are improved.

[0021] Further, the fixing member 3 is a flange structure or a welding structure, which enhances the adaptability of the equipment in various application scenarios. Among them, the flange connection structure is convenient for on-site rapid assembly and disassembly maintenance and is suitable for occasions with high requirements for equipment maintainability; the welding structure provides higher mechanical strength and stability and is suitable for working conditions with high vibration or long-term continuous operation. The flexible fixing method effectively improves the safety and reliability of the overall structure of the equipment, and at the same time optimizes the on-site construction process and later maintenance efficiency.

[0022] The screw machine further includes an oil mist separation assembly 7. The oil mist separation assembly 7 is installed on the support plate 2, is connected to the compression assembly 4, and the oil mist separation assembly 7 is also internally communicated with the air storage tank 1.

[0023] Such as Figure 2As shown in the figure, an oil return pipe 71 is provided at the bottom of the oil mist separation component 7, and it is connected to the oil storage component 52 through the oil return pipe 71. Introducing the oil mist separation component 7 significantly improves the purity of the compressed air, prevents the oil mist from directly entering the air storage tank 1 and causing pollution. At the same time, the recovered lubricating oil can be used for re-lubrication, improving the utilization efficiency of the oil product and reducing the operating cost. Further, the oil mist separation component 7 is integrally arranged on the support plate 2, forming a closed-loop system with the compression component 4 and the air storage tank 1, effectively reducing the space for wiring and piping, and improving the overall machine integration and operating reliability.

[0024] A number of baffles 72 are provided inside the oil mist separation component 7. The baffles 72 divide the bottom cavity of the oil mist separation component 7 into multiple regions, which can effectively block the air cyclone inside the oil mist separation component 7 and prevent the problem of false high oil level affecting oil drainage.

[0025] As Figure 1 shown in the figure, a number of moving wheel sets 8 are provided at the bottom of the air storage tank 1. A braking device is provided on the moving wheel sets 8 for realizing the movement and positioning of the screw machine, so that the equipment can be applied to a variety of different installation and operating environments. By equipping with the braking device, the problem of instability caused by movement during operation or maintenance of the equipment is effectively solved, and the safety and operation convenience during use are improved.

[0026] A push-pull handrail is provided at the end of the air storage tank 1. The push-pull handrail provides a safe and stable force application point, reducing the labor intensity of human-machine interaction. At the same time, as an auxiliary structure, the handrail further protects the end of the air storage tank 1 from accidental collision, which is beneficial to extending the service life of the equipment.

[0027] A pressure detection module and a temperature detection module are provided inside the compression component 4. The pressure detection module and the temperature detection module are respectively connected to the control module. Based on the detection data of the pressure detection module and the temperature detection module, the control module performs variable-frequency regulation on the drive motor 41 through the variable-frequency speed regulation module 6. Specifically, when the air pressure inside the compression component 4 is higher than the preset air pressure threshold or the temperature is lower than the preset temperature threshold, the control module sets the drive motor 41 to a high-frequency operation state to optimize the energy consumption level and prevent condensation from occurring inside the compression component 4.

[0028] The above is the description of the embodiments of the present invention. Through the above description of the disclosed embodiments, those skilled in the art can implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel points disclosed herein.
