Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, and in particular to an antifreeze screw air compressor. Background Technology

[0002] Screw air compressors, with their significant advantages such as high efficiency, strong stability, and convenient maintenance, have been widely used in many fields, including industrial production, construction, and mining. However, in low-temperature environments, screw air compressors face numerous challenges in operation.

[0003] Coolant in the cooling system is prone to freezing at low temperatures. Once the coolant freezes, it will not only cause the cooling system to malfunction, but also generate huge pressure due to the expansion of the frozen coolant, which can cause the cooler, pipes and other components to rupture and be damaged, thus affecting the overall operation of the air compressor and even causing equipment failure and shutdown. Utility Model Content

[0004] To address the above problems, this utility model provides an antifreeze screw air compressor.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] An antifreeze screw air compressor includes a body, on which a cooling module, a lubrication module, a heating module and a control module are provided. The cooling module, lubrication module, heating module and control module are interconnected to improve the antifreeze performance of the body.

[0007] The control module includes a temperature sensor, a controller, and a display screen. The temperature sensor monitors the internal temperature of the machine in real time. The controller automatically controls the working status of the heating module, cooling module, and lubrication module according to a preset temperature threshold. When the temperature sensor detects that the lubricating oil temperature is lower than the preset lower limit, the controller starts the heating module to heat the lubricating oil. When the temperature reaches the normal range, heating stops. The display screen is used to display the working status of the machine, which facilitates the operator to monitor the operation of the equipment in real time.

[0008] Preferably, the cooling module includes a cooler, a cooling fan, and a circulating water pump. The cooler is used to cool the compressed high-temperature gas, the cooling fan accelerates airflow and improves cooling efficiency, and the circulating water pump ensures the circulation of coolant in the cooling system.

[0009] Preferably, the coolant is a special antifreeze coolant with a low freezing point to prevent the coolant from freezing at low temperatures.

[0010] Preferably, the lubrication module includes a lubricating oil tank, an oil pump, and oil pipes. The lubricating oil tank is used to store lubricating oil, and the oil pump delivers the lubricating oil to various parts of the machine body through the oil pipes, thereby playing a role in lubrication and cooling.

[0011] Preferably, the lubricating oil is a special lubricating oil with good low-temperature performance, which can maintain good fluidity in low-temperature environments and ensure normal lubrication of various components.

[0012] Preferably, the heating module consists of an electric heater and a heating tube. The electric heater is installed inside the lubricating oil tank and cooler. In low-temperature environments, the electric heater is activated to heat the lubricating oil, coolant, and pipelines to prevent freezing.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The cooler adopts a finned structure to increase the heat dissipation area. The cooling fan can automatically adjust its speed according to the temperature. The circulating water pump can stably drive the coolant circulation. The lubricating oil tank has double-layer insulation with a corrosion-resistant inner layer.

The special lubricating oil has good low-temperature fluidity, ensuring that all components can still be well lubricated at low temperatures.

[0015] 2. The heating module employs a high-efficiency PTC ceramic heating element, capable of heating lubricating oil, coolant, and pipelines in low-temperature environments to prevent freezing and ensure the normal operation of the lubrication and cooling systems.

[0023] Reference Figure 1-3 An antifreeze screw air compressor includes a body 1, on which a cooling module 2, a lubrication module 3, a heating module 4 and a control module 5 are integrated. The modules work together to form a complete antifreeze system, which significantly improves the working performance and reliability of the body 1 in low-temperature environments.

[0024] Cooling module 2, a key component ensuring stable operation of the air compressor, consists of a cooler 21, a cooling fan 22, and a circulating water pump 23. The cooler 21 employs a high-efficiency finned structure, increasing the heat dissipation area to rapidly dissipate heat from the compressed high-temperature gas, achieving efficient cooling. The cooling fan 22, located near the cooler 21, uses variable frequency speed control technology to automatically adjust its speed according to temperature changes in the cooler 21, accelerating airflow when needed to significantly improve cooling efficiency and ensure the gas temperature quickly drops to a suitable range. The circulating water pump 23 is a high-performance centrifugal pump with stable flow output, continuously and stably driving the coolant to circulate within the cooling system. This allows the coolant to absorb heat at the cooler 21 and release heat at other heat dissipation points, forming an efficient heat exchange cycle.

[0025] To cope with low-temperature environments, a special antifreeze coolant with a low freezing point is selected. This coolant is specially formulated, and its freezing point is much lower than that of conventional coolants. It can remain liquid even under extreme low-temperature conditions, preventing the coolant from freezing and damaging components such as the cooler 21 and pipes due to the expansion of the frozen coolant, thus ensuring the normal operation of the cooling system.

[0026] The lubrication module 3 consists of a lubricating oil tank 31, an oil pump 32, and oil pipes 33, playing an indispensable role in ensuring the normal operation of all components of the air compressor. The lubricating oil tank 31 adopts a double-layer insulation design. The inner layer is made of corrosion-resistant stainless steel, effectively preventing lubricating oil contamination, while the outer layer is made of high-efficiency insulation material, reducing heat exchange between the lubricating oil and the external environment and maintaining a relatively stable lubricating oil temperature. The oil pump 32 is a high-precision gear pump with good self-priming capability and stable pressure output. It accurately and stably delivers the lubricating oil from the lubricating oil tank 31 to all moving parts of the machine body 1 through the oil pipes 33, forming a uniform lubricating oil film on the surface of the parts. This provides both lubrication and cooling, reducing frictional resistance between parts, minimizing wear, and extending the service life of the parts.

[0027] For low-temperature environments, a special lubricating oil with excellent low-temperature performance is selected. This lubricating oil has excellent low-temperature fluidity, and its viscosity changes little even at extremely low temperatures. It can quickly form an effective lubricating film on the surface of various components, ensuring that each component can still be well lubricated and maintain normal operation in low-temperature environments.

[0028] Heating module 4, consisting of electric heater 41 and heating tube 42, is a crucial protective unit ensuring the normal operation of the air compressor in low-temperature environments. Electric heater 41 utilizes a high-efficiency PTC ceramic heating element, offering advantages such as high heating efficiency, long service life, and good safety. Electric heater 41 is installed inside the lubricating oil tank 31 and the cooler 21, while heating tube 42 is laid along the oil pipe 33 and coolant pipeline. In low-temperature environments, when the ambient temperature or the internal temperature of the equipment drops to a certain level, electric heater 41 activates, heating the lubricating oil in the lubricating oil tank 31, the coolant in the cooler 21, and the oil pipe 33 and coolant pipeline through heat conduction and radiation. This raises the temperature of the lubricating oil and coolant, preventing freezing and ensuring the normal operation of the lubrication and cooling systems.

[0029] The control module, comprising a temperature sensor 51, a controller, and a display screen 52, is the core hub for the entire air compressor to achieve intelligent anti-freeze operation. The temperature sensor 51 uses a high-precision platinum resistance temperature sensor, characterized by fast response and high measurement accuracy, enabling real-time and accurate monitoring of the temperatures of key components inside the compressor body 1, such as the lubricating oil tank 31, the cooler 21, and various moving parts. The controller employs a high-performance microprocessor with built-in advanced control algorithms, capable of automatically and precisely controlling the operating status of the heating module 4, cooling module 2, and lubrication module 3 based on preset temperature thresholds.

[0030] When temperature sensor 51 detects that the lubricating oil temperature is lower than the preset lower limit, the controller immediately issues a command to start heating module 4 to heat the lubricating oil. As the temperature gradually rises, the controller automatically stops heating module 4 when it reaches the normal range. Similarly, for cooling module 2 and lubrication module 3, the controller will also adjust the speed of cooling fan 22, the flow rate of circulating water pump 23, and the working status of oil pump 32 according to temperature changes and preset programs to achieve coordinated and efficient operation of each module. Display screen 52 adopts a high-definition color touch screen, which can intuitively and clearly display the working status of machine body 1, including the temperature of each part, the operating parameters of each module, equipment running time, and other information, so that operators can monitor the equipment operation in real time, detect abnormalities in a timely manner, and handle them. At the same time, display screen 52 also has an operation interface function, allowing operators to perform parameter settings, equipment start and stop operations, etc. through the touch screen, improving the ease of operation and intelligence of the equipment.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
