Description

Technical Field

[0001] This utility model relates to a two-stage compression screw air compressor. Background Technology

[0002] The cooler of a screw air compressor is usually placed on the side of the compressor, resulting in a rectangular shape that may be too long to install in some situations. Furthermore, the traditional layout of screw air compressors can present difficulties in maintenance and hoisting. Utility Model Content

[0003] The main technical problem to be solved by this utility model is to provide a two-stage compression screw air compressor, which changes the internal layout of the air compressor to reduce the length of the air compressor, making it convenient for installation in various scenarios.

[0004] To address the aforementioned technical problems, this utility model provides a two-stage screw air compressor, comprising: a cubic frame, a support plate at the bottom of the frame, a two-stage screw air compressor main unit and an oil-gas separator mounted on the support plate, and a cooler and a cooling fan mounted above the two-stage screw air compressor main unit. The air inlet of the cooling fan is connected to the air outlet of the screw air compressor main unit via an air guide shroud. The frame, corresponding to the oil-gas separator, also has an independent air inlet assembly connected to the air inlet of the screw air compressor main unit. The air inlet assembly includes an air inlet, an oil filter, an air filter, and an air inlet pipe. The air inlet is connected to the air inlet of the two-stage screw air compressor main unit via the oil filter, the air filter, and the air inlet pipe.

[0005] The cooling fan is fixed to the upper surface of the frame, and a baffle extends downward along the height direction from the lower surface of the frame. The baffle is provided with a lifting hole.

[0006] The two sides of the frame corresponding to the area where the cooler and cooling fan are located are the air intake surfaces.

[0007] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0008] This invention provides a two-stage screw air compressor that adopts a cubic shape compared to the traditional rectangular shape, offering a new selection option when space is limited, especially in spaces with a maximum length restriction. It also features an independent air intake assembly, enhancing heat dissipation for the compressor unit and facilitating user maintenance and replacement of the oil and air filters within the intake assembly.

[0013] To make the technical solution and features of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific examples. It should be understood that these examples are only for illustrating this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model by those skilled in the art in various equivalent forms fall within the scope defined by the appended claims.

[0014] refer to Figures 1-4 This embodiment provides a two-stage screw air compressor, including: a cubic frame 1, a support plate 2 placed at the bottom of the frame 1, a two-stage screw air compressor main unit 3 and an oil-gas separator 6 disposed on the support plate 2, and a cooler and a cooling fan 4 disposed above the two-stage screw air compressor main unit 3. The air inlet of the cooling fan 4 is connected to the air outlet of the screw air compressor main unit 3 through an air guide shroud 5. The side of the frame 1 corresponding to the oil-gas separator 6 is also provided with a connection to the screw air compressor main unit 3. An independent air inlet assembly 7 is provided with an air inlet, an oil filter, an air filter, and an air inlet pipe. The air inlet is connected to the air inlet of the two-stage screw air compressor main unit 3 through the oil filter, the air filter, and the air inlet pipe. The cooling fan 4 is fixed on the upper surface of the frame 1, and the lower surface of the frame 1 extends downward along the height direction to form a baffle 8, which is provided with a lifting hole 9. The two sides of the frame 1 corresponding to the area where the cooler and the cooling fan 4 are located are the air inlet surfaces 10.

[0015] The aforementioned two-stage screw air compressor adopts a cubic shape compared to the traditional rectangular shape, providing a new selection option when the customer's site is limited, especially when there is a space with a limit on the maximum length. It also features an independent air intake assembly, which enhances heat dissipation for the compressor unit 3 and facilitates maintenance and replacement of the oil filter and air filter within the air intake assembly. Furthermore, the lifting hole is located on the baffle plate, preventing interference with the external mounting panel during hoisting.

[0016] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
