A condensate drainage structure for air compressor stages

Abstract

This utility model relates to the field of air compressor condensate drainage technology, and discloses an interstage condensate drainage structure for air compressors, including a collection pipe, a transparent funnel, and a drain branch pipe. An installation hole is formed at the top of the collection pipe, and the transparent funnel is embedded in the hole. The end of the drain branch pipe extends into the cavity of the transparent funnel. This solution allows for real-time observation of the condensate drainage status through the transparent funnel, and the funnel cavity physically constrains the water flow, solving the problem that traditional drain pipe structures cannot simultaneously achieve both visualization and splash prevention.

Description

Technical Field

[0001] This utility model relates to the field of air compressor condensate drainage technology, specifically to an interstage condensate drainage structure for air compressors. Background Technology

[0002] When an air compressor is operating, the ambient air containing a certain level of humidity is compressed and cooled, causing water vapor in the air to condense into liquid water. If this condensate is not drained in time, it can lead to safety accidents such as water hammer, corrosion, and lubricating oil emulsification in the compressor. Furthermore, the condensate generated between air compressor stages is highly clean and has significant recycling value. Therefore, timely and efficient drainage of condensate from between air compressor stages is crucial for stable equipment operation and an important means of achieving energy conservation and environmental protection. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide an interstage condensate drainage structure for air compressors, which is simple to manufacture, realizes condensate recovery, and enables real-time observation of the drainage process and prevents splashing.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a condensate drainage structure for an air compressor, characterized in that it includes a collection pipe, several transparent funnels, and drainage branch pipes corresponding to the transparent funnels; the collection pipe has an installation hole at its top, the transparent funnels are embedded in the installation hole of the collection pipe, and the ends of the drainage branch pipes extend into the cavity of the transparent funnels.

[0005] Preferably, the collection pipe is made of carbon steel, with one end sealed by a pipe cap and the other end extending to connect to a drainage pit or a collection well.

[0006] Preferably, the outlet end of the collection pipe (1) is inclined downward relative to the sealing end, with an inclination angle of 1-3°, to guide the condensate to the drainage pit or collection well.

[0007] Preferably, the mounting hole at the top of the collection tube is a round hole or a square hole.

[0008] Preferably, the transparent funnel is a conical triangular funnel made of highly transparent glass or engineering plastic.

[0009] Preferably, the diameter or side length of the mounting hole at the top of the collection tube is 2-3 mm larger than the lower outer diameter of the transparent funnel.

[0010] Preferably, the drain branch pipe originates from the drain port of the air compressor interstage cooler and extends 50-100mm into the interior of the transparent funnel cavity.

[0011] Preferably, the outlet of the hydrophobic branch pipe is located on the center line of the transparent funnel to prevent water from splashing due to impact on the side wall of the funnel.

[0012] Preferably, the end of the drainage branch pipe is bent vertically.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] 1. The main pipe of this utility model can be made on-site using steel pipes, with locally sourced materials; the installation holes are round or square, making the manufacturing process simple.

[0015] 2. The transparent funnel of this utility model uses standardized finished parts, which are widely available in the market; the transparent funnel is directly embedded in the mounting hole, making disassembly convenient.

[0016] 3. In this utility model, a transparent funnel is used to achieve real-time visualization of the hydrophobic process.

[0017] 4. In this utility model, the drainage branch pipe extends vertically into the interior of the transparent funnel wall to prevent water from splashing out of the drainage branch pipe. Attached Figure Description

[0018] Figure 1 This is a schematic diagram of the structure of this utility model.

[0019] In the diagram: 1-summit pipe; 2-transparent funnel; 3-drainage branch pipe. Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following embodiments will provide a more detailed description of this utility model.

[0021] Example: Figure 1 As shown, an interstage condensate drainage structure for an air compressor consists of three components, from bottom to top: a main pipe 1, three spaced transparent funnels 2, and three drainage branch pipes 3.

[0022] Among them, the main pipe 1 is a DN300 carbon steel pipe, one end of which is sealed with a pipe cap, and the other end extends to the water collection well to store the collected condensate for later use.

[0023] Three φ55mm circular mounting holes are evenly distributed on the upper surface of the main tube 1.

[0024] The transparent funnel 2 is a thickened transparent plastic funnel with a diameter of 150mm. It is an industrial-grade finished product. The outer diameter of the narrow end of the transparent funnel 2 is slightly smaller than the diameter of the mounting hole, so that it can be inserted into the circular mounting hole of the collection tube 1 to achieve embedded installation.

[0025] The drain branch pipe 3 is led out from the drain port of the interstage cooler of the air compressor. Its end is bent into a vertical shape. The vertical part coincides with the center line of the transparent funnel 2, and the end outlet penetrates into the cavity of the transparent funnel 2 by 50-100mm (preferably 80mm). The deviation between the end outlet of the drain branch pipe 3 and the center line of the funnel is ≤3mm.

[0026] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
