Description

Technical Field

[0002] An air compressor is an air compressor, and common air compressors include screw air compressors. During the operation of the air compressor, heat will be generated when the air is compressed, so the compressed air needs to be cooled, especially in the technical solution of a multi-stage air compressor, which requires multi-stage compression to provide compressed gas with a higher degree of compression. When transferring gas between adjacent air compressor hosts, the lower the inlet temperature, the more free water can be precipitated, and the gas entering the compressor chamber of the air compressor host is drier, which is beneficial to improving the volumetric efficiency of the air compressor host. Therefore, a cooler needs to be configured, so there is a pipeline setting for transporting the gas to the next level of the air compressor host. In the prior art, the main idea is to connect through pipelines, and the pipelines are long and have many elbows. In this way, when multiple coolers are set, it will be more serious to cause a longer gas path on the one hand, and a larger and more complex structure on the other hand. Utility Model Content

The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.

[0017] The utility model is further described in detail below:

[0018] like Figures 1 to 3 As shown, the present disclosure proposes an air compressor, including an air compressor main unit, and also including a first cooler 1 and a second cooler 2, the first cooler 1 and the second cooler 2 are adjacent in the horizontal direction and arranged parallel to each other to obtain a horizontal interval, a first direct pipe 9 is arranged between the first cooler 1 and the second cooler 2 in the horizontal interval to connect, the air compressor main unit is located on the upper side of the first cooler 1 and is adjacently arranged to obtain a vertical interval, and a second direct pipe 10 is arranged between the air compressor main unit and the first cooler 1 in the vertical interval to connect. In this example, the air compressor main unit is the first air compressor main unit 5.

[0019] like Figure 1 As shown, the air outlet of the air compressor main unit is arranged on the upper side of the first cooler 1 and is provided with a first connecting flange 11, a second direct pipe 10 is arranged at the position of the first cooler 1 corresponding to the first connecting flange 11, a second connecting flange 12 is arranged at the upper end of the second direct pipe 10, and the first connecting flange 11 is detachably connected to the second connecting flange 12 in a vertical manner. This makes disassembly and assembly convenient.

[0020] like Figure 2 As shown, the first direct pipe 9 includes a first part 13 and a second part 14 which are coaxially arranged. The first part 13 is arranged at the first cooler 1 and a third connecting flange 15 is arranged. The second part 14 is arranged at the second cooler 2 and a fourth connecting flange 16 is arranged. The third connecting flange 15 is detachably connected to the fourth connecting flange 16 in the horizontal direction.

[0021] like Figure 2As shown, a post-cooling air outlet 17 is provided on the upper side of the second cooler 2, and the post-cooling air outlet 17 is connected to one end of a first elbow 18, and the other end of the first elbow 18 is connected to the next-stage air compressor.

[0022] like Figure 3 As shown, the next-stage air compressor includes the next-stage air compressor main unit, the third cooler 3 and the fourth cooler 4. The third cooler 3 and the fourth cooler 4 are adjacent to each other in the horizontal direction and are arranged parallel to each other to obtain a horizontal interval. A first direct pipe 9 is arranged between the third cooler 3 and the fourth cooler 4 in the horizontal interval to connect.
