Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and more specifically, to a screw air compressor. Background Technology

[0002] An air compressor is a device that converts electricity into gas pressure energy, providing power by compressing air. It is widely used in various industrial and non-industrial processes, such as manufacturing, construction, automobile repair, painting, and cleaning. Depending on the working principle and design, air compressors can be divided into several types. Screw air compressors are a common type of air compression device, particularly suitable for industrial applications that require a continuous air supply. They compress gas through a pair of meshing helical rotors. One rotor has convex teeth, while the other has corresponding grooves. The two are precisely matched, and when they rotate, air is drawn in, compressed, and finally discharged.

[0003] Existing screw air compressors include a main unit, which is the core component of the compressor. It consists of a pair of precision-manufactured male and female rotors. These two rotors are precisely meshed by synchronous gears. When they rotate, air is drawn in, compressed, and discharged. During operation, the motor provides power to the compressor, driving the rotors to rotate. The air entering the compressor is filtered through the intake filter to prevent dust and other impurities from entering the machine, thus protecting the main unit and other components from damage. Modern screw air compressors are usually equipped with intelligent control systems that can automatically adjust the operating status, monitor performance parameters, and perform fault diagnosis.

[0004] In practical applications, existing technologies suffer from the following problems: when air is compressed by the screw rotor during operation, its volume decreases while its pressure increases. During this process, mechanical energy is converted into heat energy, causing the temperature of the air and equipment components to rise. Equipment in high-temperature environments is prone to damage or performance degradation. Therefore, a screw air compressor is proposed. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, this utility model provides a screw air compressor. It uses a drive motor to rotate a screw rotor inside the compressor housing. As the rotor rotates, air enters through the intake pipe, is gradually compressed, and finally discharged through the outlet pipe. The heat generated during air compression is conducted to the interior of the cooling housing via heat-conducting fins. Multiple heat-conducting fins are fixed between the compressor housing and the cooling housing, increasing the heat dissipation area and providing support. Conductive cooling fins cool the liquid inside the cooling housing, effectively controlling the internal temperature of the compressor, preventing overheating that could damage the equipment or degrade its performance, and ensuring the compressor operates at a suitable operating temperature.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A screw-type air compressor includes a compressor housing, with two helical rotors symmetrically rotatably connected to the inner cavity of the compressor housing. A partition is fixedly connected to the inner cavity of the compressor housing, and a synchronous gear is fixedly connected to the connecting shaft of the helical rotors through the partition. A cooling assembly is installed on the outer surface of the compressor housing, and a support assembly is installed on the lower surface of the cooling assembly. The cooling assembly includes multiple heat-conducting fins symmetrically fixedly connected to the outer surface of the compressor housing, and a cooling housing is fixedly connected to the outer surface of the heat-conducting fins. Two semiconductor cooling chips are symmetrically embedded on the outer surface of the cooling housing. The support assembly includes multiple sleeves symmetrically fixedly connected to the lower surface of the cooling housing. An adjusting rod is inserted through the inner cavity of each sleeve, and multiple adjusting holes are evenly opened on the adjusting rod. An insert rod is inserted through the adjusting holes and the inner cavity of the sleeve, and a moving plate is fixedly connected to one end of the insert rod. A spring is sleeved on the outer surface of the insert rod.

[0010] Furthermore, the upper surface of the compressor housing is connected to an air inlet pipe, and the lower surface of the compressor housing is connected to an air outlet pipe. The outer surfaces of the air inlet pipe and the air outlet pipe are fixedly connected to the cooling housing.

[0011] Furthermore, a drive motor is fixedly connected to one side of the compressor housing, and the output shaft end of the drive motor passes through the compressor housing and is fixedly connected to the end of the spiral rotor shaft.

[0012] Furthermore, there are two synchronous gears, which are meshed together. The cold end of the semiconductor refrigeration chip is located inside the cooling housing, and the hot end of the semiconductor refrigeration chip is located outside the cooling housing.

[0013] Furthermore, a water inlet pipe is connected to the outer surface of the cooling housing, and a valve is installed on the water inlet pipe.

[0014] Furthermore, one end of the spring is fixedly connected to the movable plate, the other end of the spring is fixedly connected to the outer surface of the sleeve rod, and the lower end of the adjusting rod is fixedly connected to the base plate.

[0015] 3. Beneficial Effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) This solution starts the drive motor to drive the spiral rotor to rotate inside the compressor housing. As the spiral rotor rotates, air enters from the intake pipe and is gradually compressed, and finally discharged through the outlet pipe. The heat generated during the air compression process is conducted to the inside of the cooling housing through the heat conduction plate. Multiple heat conduction plates are fixed between the compressor housing and the cooling housing, which increases the heat dissipation area and also plays a supporting role. The liquid inside the cooling housing is cooled by the conductor cooling plate, which effectively controls the internal temperature of the compressor, prevents equipment damage or performance degradation caused by overheating, and ensures that the compressor can operate at a suitable working temperature.

[0018] (2) This solution achieves height adjustment by sliding the plug rod inside the sleeve rod, and by pulling the plug rod outward to move it into the adjustment holes of different heights, the position of the adjusted plug rod is locked. The spring provides an automatic reset function. At the same time, the base plate increases the contact area with the ground, improving the overall stability. According to the needs, the compressor can be installed at a suitable height, which makes it convenient for operators to carry out daily inspection, maintenance and repair work, and ensures that the compressor is installed at a safe height. This not only helps to protect the equipment itself, but also prevents accidents, such as avoiding damage to the equipment caused by natural disasters such as floods. Attached Figure Description

[0028] Example 1

[0029] Reference Figure 1 , Figure 2 and Figure 3This is the first embodiment of the present invention. This embodiment provides a screw air compressor, including a compressor housing 1, a cooling assembly 2, and a support assembly 3. Two helical rotors 102 are symmetrically rotatably connected to the inner cavity of the compressor housing 1. A partition 101 is fixedly connected to the inner cavity of the compressor housing 1. A synchronous gear 103 is fixedly connected to the connecting shaft of the helical rotors 102 through the partition 101. A cooling assembly 2 is installed on the outer surface of the compressor housing 1, including a plurality of heat-conducting plates 201 symmetrically fixedly connected to the outer surface of the compressor housing 1. A cooling housing 202 is fixedly connected to the outer surface of the heat-conducting plates 201. Two semiconductor cooling plates 203 are symmetrically embedded on the outer surface of the cooling housing 202.

[0030] Specifically, an intake pipe 105 is connected to the upper surface of the compressor housing 1, and an outlet pipe 106 is connected to the lower surface of the compressor housing 1. The outer surfaces of the intake pipe 105 and the outlet pipe 106 are fixedly connected to the cooling housing 202. A drive motor 104 is fixedly connected to one side of the compressor housing 1. The output shaft of the drive motor 104 passes through the compressor housing 1 and is fixedly connected to the shaft end of the spiral rotor 102. There are two synchronous gears 103, which are meshed together. The cold end of the semiconductor refrigeration chip 203 is located inside the cooling housing 202, and the hot end of the semiconductor refrigeration chip 203 is located outside the cooling housing 202. A water inlet pipe 204 is connected to the outer surface of the cooling housing 202, and a valve is installed on the water inlet pipe 204.

[0031] Furthermore, the drive motor 104 is started, which drives the spiral rotor 102 to rotate inside the compressor housing 1. The two spiral rotors 102 are symmetrically installed and maintain a precise relative position and speed through the synchronous gear 103. As the spiral rotors 102 rotate, air enters from the intake pipe 105 and is gradually compressed, and finally discharged through the exhaust pipe 106. The two spiral rotors 102 are a pair of precision-manufactured male and female rotors. The two rotors maintain precise meshing. When they rotate, air is drawn in, compressed and discharged. The partition 101 divides the compressor housing 1 into a compression zone and a transmission zone.

[0032] The heat generated during air compression is conducted to the interior of the cooling shell 202 through the heat-conducting plate 201. Multiple heat-conducting plates 201 are fixed between the compressor shell 1 and the cooling shell 202, which increases the heat dissipation area and also provides support. The semiconductor cooling chip 203 is installed on the cooling shell 202, with the cold end located inside the cooling shell to absorb the heat of the liquid, and the hot end located outside to release heat, thereby cooling the cooling liquid inside the cooling shell 202.

[0033] The semiconductor cooling chip 203 utilizes the Peltier effect (semiconductor cooling chips are a mature existing technology, and their connection methods and the working principles of each component are existing technology for those skilled in the art, and will not be elaborated further here) to directly absorb heat at the cold end and release heat at the hot end. It is an effective local cooling method that can rapidly cool the coolant. The coolant is mainly used to absorb and remove excess heat generated during compression, ensuring that the compressor can operate at a suitable operating temperature. Common coolants include water, ethylene glycol aqueous solution (antifreeze), mineral oil, etc. The operator should choose according to the actual situation. The function of the water inlet pipe 204 is mainly to facilitate the injection and circulation of coolant. Through valve control, the flow rate of coolant can be easily adjusted and the coolant can be replaced to maintain the best cooling effect.

[0034] Example 2

[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the second embodiment of the present invention. Based on the previous embodiment, a support assembly 3 is installed on the lower surface of the cooling assembly 2. The support assembly 3 includes multiple sleeve rods 301 symmetrically fixedly connected to the lower surface of the cooling housing 202. An adjusting rod 302 is inserted into the inner cavity of the sleeve rod 301. Multiple adjusting holes 303 are evenly opened on the adjusting rod 302. An insert rod 304 is inserted into the adjusting hole 303 and the inner cavity of the sleeve rod 301. A moving plate 306 is fixedly connected to one end of the insert rod 304. A spring 305 is sleeved on the outer surface of the insert rod 304.

[0036] Specifically, one end of the spring 305 is fixedly connected to the movable plate 306, the other end of the spring 305 is fixedly connected to the outer surface of the sleeve rod 301, and the lower end of the adjusting rod 302 is fixedly connected to the base plate 307.

[0037] Furthermore, when the compressor is supported, the height is adjusted by sliding the insert rod 304 within the sleeve rod 301. By pulling the insert rod 304 outward, it moves into the adjustment holes 303 at different heights, locking the adjusted insert rod 304 in place. The spring 305 provides an automatic reset function. At the same time, the base plate 307 increases the contact area with the ground, improving overall stability and reducing the risk of tilting due to uneven ground. The larger contact area also helps to distribute the weight of the compressor, further reducing the risk of damage caused by excessive local pressure. This design allows the screw air compressor to adapt to different ground conditions and installation requirements, ensuring equipment stability while facilitating maintenance and adjustment.

[0038] Working principle: During operation, the drive motor 104 is started, which drives the spiral rotor 102 to rotate inside the compressor housing 1. The two spiral rotors 102 are symmetrically installed and maintain a precise relative position and speed through the synchronous gear 103. As the spiral rotors 102 rotate, air enters through the intake pipe 105 and is gradually compressed, eventually being discharged through the exhaust pipe 106. The two spiral rotors 102 are a pair of precision-manufactured male and female rotors, which maintain precise meshing. When they rotate, air is drawn in, compressed, and discharged. The heat generated during air compression is conducted to the interior of the cooling housing 202 through the heat-conducting fins 201. Multiple heat-conducting fins 201 are fixed to the compressor housing 1 and the cooling housing 202. Between the shells 202, the heat dissipation area is increased and a supporting function is provided. The semiconductor cooling chip 203 is installed on the cooling shell 202, with the cold end located inside the cooling shell to absorb heat from the liquid, and the hot end located outside to release heat, thus cooling the cooling liquid inside the cooling shell 202. The water inlet pipe 204 is used to inject and output cooling liquid. When the compressor is supported, the height is adjusted by sliding the plug rod 304 in the sleeve rod 301. By pulling the plug rod 304 outward, it can be moved into the adjustment hole 303 at different heights, and the adjusted plug rod 304 is locked in position. The spring 305 provides an automatic reset function. At the same time, the base plate 307 increases the contact area with the ground, improving the overall stability.

[0039] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
