Description

Technical Field

[0001] This utility model relates to the technical field of air compressor auxiliary equipment, and more specifically, to a drainage mechanism for an air compressor storage tank. Background Technology

[0002] During operation, the air compressor draws in water vapor, which condenses into liquid water in the air tank after compression and cooling. If this condensate is not drained in time, it will accumulate at the bottom of the air tank, causing internal corrosion, shortening the equipment's lifespan, and potentially entering subsequent air-using equipment with the compressed air, affecting the normal operation of pneumatic components and even contaminating the production process.

[0003] Based on the above, the inventors have discovered that there are currently two main methods for draining air compressor storage tanks: manual drain valves, typically ball valves or needle valves. Operators need to manually open the valves periodically (e.g., daily) to drain the water. This method relies entirely on manual labor, posing risks of forgetting to drain or delayed drainage, and is inconvenient to operate in harsh environments such as high temperatures and dust. Mechanical automatic drainers, on the other hand, automatically open and close solenoid valves via time control or liquid level sensing. While achieving automation, their structure is relatively complex, electronic components are susceptible to failure due to humid environments, and the float or sensor probe is easily clogged by sludge and impurities, leading to malfunctions or complete failure, resulting in high maintenance costs. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a drainage mechanism for air compressor storage tanks, aiming to achieve a more practical purpose. Utility Model Content

[0004] 1. Technical problems to be solved

It can realize reliable timed automatic drainage while retaining the convenient manual drainage function. Moreover, the overall structure is simple, there are no electronic components, it has strong resistance to oil and impurities, is not easy to clog, and is easy to maintain, which significantly improves the reliability and convenience of drainage.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A drainage mechanism for an air compressor storage tank includes a main pipeline, a shut-off valve installed on one side of the main pipeline, a tee connector installed on one side of the shut-off valve, a connecting pipe one and a connecting pipe two threadedly connected to one side and the other side of the tee connector, a filter device installed on one side of the connecting pipe two, a U-shaped pipe installed on one side of the filter device, a bend threadedly connected to one side of the U-shaped pipe, a one-way valve installed on one side of the bend, a drain pipe two threadedly connected to one side of the one-way valve, a manual drain valve installed on one side of the connecting pipe one, and a drain pipe one threadedly connected to one side of the manual drain valve.

[0009] Furthermore, the main pipeline is connected to the drain port at the bottom of the gas storage tank, and the shut-off valve is a ball valve.

[0010] Furthermore, the filtration device is a Y-type filter with a mesh size of 60 mesh.

[0011] Furthermore, the main pipeline, connecting pipe one, connecting pipe two, and bend are all made of stainless steel.

[0012] Furthermore, the U-shaped tube is made of copper tubing with an outer diameter of 8mm, and its highest point is set at a height of 15cm from the bottom of the gas storage tank, which is higher than the maximum allowable water level inside the gas storage tank.

[0013] Furthermore, the one-way valve is a check valve, and its opening pressure is less than 0.01 MPa.

[0014] Furthermore, a threaded head is fixedly connected to one end of the main pipeline, and an internal thread is provided on the inner side wall of the shut-off valve, with the threaded head threadedly connected to the internal thread.

[0015] 3. Beneficial effects

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

[0017] (1) This solution utilizes an automatic drainage assembly consisting of a U-shaped pipe and a one-way valve, employing the siphon principle and gravity to achieve timed automatic drainage of condensate. When the pressure generated by the weight of the water in the U-shaped pipe is sufficient to overcome the opening pressure of the one-way valve, the valve opens, and the water is rapidly discharged under negative pressure and gravity. This process requires no electricity, eliminates the risk of moving parts jamming, and features an extremely simple, reliable, and durable structure with strong resistance to oil and impurities, fundamentally solving the problems of easy clogging and damage in traditional automatic drainers.

[0018] (2) This design, by setting up a manual drainage branch and retaining a shut-off valve, provides dual drainage protection for the device. In daily use, automatic drainage is achieved via the U-shaped pipe; when a thorough cleaning of the gas storage tank or maintenance of the drainage mechanism is required, the shut-off valve can be closed and the manual drainage valve opened for complete emptying and cleaning. This design ensures both the convenience of automated operation and the flexibility for emergency response and maintenance, making it safe, reliable, and extremely easy to maintain.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] Please see Figure 1-4A drainage mechanism for an air compressor storage tank includes a main pipeline 1, a shut-off valve 2 installed on one side of the main pipeline 1, a three-way connector 3 installed on one side of the shut-off valve 2, a connecting pipe 4 and a connecting pipe 7 threadedly connected to one side and the other side of the three-way connector 3, a filter device 8 installed on one side of the connecting pipe 7, a U-shaped pipe 9 installed on one side of the filter device 8, a bend 10 threadedly connected to one side of the U-shaped pipe 9, a one-way valve 11 installed on one side of the bend 10, a drain pipe 12 threadedly connected to one side of the one-way valve 11, and the end of the drain pipe 12 leads sewage to a drainage ditch. A manual drain valve 5 is installed on one side of the connecting pipe 4, and a drain pipe 6 is threadedly connected to one side of the manual drain valve 5.

[0028] See Figure 1 and Figure 2 The main pipeline 1 is connected to the drain port at the bottom of the gas storage tank. The shut-off valve 2 is a ball valve. The main pipeline 1 is used to connect to the drain port for sewage discharge.

[0029] See Figure 1 and Figure 4 The filter device 8 is a Y-type filter with a mesh size of 60 mesh. The Y-type filter can effectively intercept oil sludge and particulate impurities in the condensate.

[0030] See Figure 1 and Figure 3 The main pipe 1, connecting pipe 4, connecting pipe 7, and bend 10 are all made of stainless steel.

[0031] See Figure 1 and Figure 2 The U-shaped tube 9 is made of copper tubing with an outer diameter of 8mm. Its highest point is set at a height of 15cm from the bottom of the gas tank, which is higher than the maximum allowable water level inside the gas tank.

[0032] See Figure 1 and Figure 4 One-way valve 11 is a check valve, and its opening pressure is less than 0.01MPa.

[0033] See Figure 1 and Figure 4 One end of the main pipeline 1 is fixedly connected to a threaded head 14, and the inner wall of the shut-off valve 2 is provided with an internal thread 13. The threaded head 14 is threadedly connected to the internal thread 13, and the threaded head 14 and the internal thread 13 are used to connect the main pipeline 1 and the shut-off valve 2.

[0034] During use: After system installation, keep shut-off valve 2 in the normally open position. Condensate in the gas tank flows into main pipe 1 under gravity. The water first passes through tee connector 3, with most of the water flowing into connecting pipe 2 7 and then to filter device 8. The purified water enters U-tube 9 and begins to accumulate. As the water level rises on the right side of the drain in U-tube 9, when the static pressure generated by the weight of the accumulated water exceeds the opening pressure of check valve 11, check valve 11 is opened, forming a siphon within U-tube 9, and the accumulated water is quickly discharged into the drain ditch. After drainage is complete, air enters U-tube 9, the siphon is interrupted, and check valve 11 automatically closes, awaiting the next water accumulation. The entire process repeats continuously, achieving automatic drainage. Manual drain valve 5 is kept closed during normal use. When it is necessary to thoroughly clean the gas tank or replace the filter, first close the shut-off valve 2 to cut off the water supply, and then open the manual drain valve 5. This will completely drain the residual water and impurities in the main pipe 1, tee joint 3, connecting pipe 1 4, connecting pipe 2 7 and filter device 8 through the drain pipe 1 6, which is convenient for maintenance.
