Description

Technical Field

[0001] This utility model relates to the field of compressed air dewatering technology, specifically to an automatic dewatering device for compressed air system pipelines. Background Technology

[0002] In compressed air systems, moisture often accumulates in the pipelines. This is because during air compression, the unsaturated water vapor in the original air becomes saturated as the pressure increases, condensing into water. As the compressed air flows and the temperature gradually decreases, water continues to condense. Therefore, compressed air pipeline systems require constant drainage. This not only reduces system efficiency but can also cause corrosion and damage to equipment.

[0003] Traditional drainage methods mostly rely on manual operation or simple mechanical devices, such as installing drain valves and manually draining water. However, these methods are cumbersome to operate, slow to respond, and have high maintenance costs. Therefore, this application is hereby submitted. Utility Model Content

[0005] An automatic drainage device for compressed air system pipelines includes a drainage tank, an inlet pipe, a float, a fixed base, rotating balls, a connecting rod, a guide device, a drainage channel, a lifting rod, a drain outlet, a limiting device, and a counterweight device. The inlet pipe is located on one side of the drainage tank, the drainage channel is located on the lower side of the drainage tank, the lifting rod is slidably disposed within the drainage channel, the drain outlet is located on the lifting rod, the limiting device is located on the lower side of the lifting rod, the counterweight device is located on the top of the lifting rod, the guide device is located within the drainage tank, the fixed base is respectively disposed on the counterweight device and the float, the rotating balls are rotatably disposed on the fixed base, and the connecting rod is disposed between the two rotating balls.

[0006] Furthermore, the counterweight device includes a fixed rod and a counterweight ball. The fixed rod is disposed at the top of the lifting rod, the counterweight ball is disposed at the top of the fixed rod, and the connecting rod connects the counterweight ball and the float.

[0007] Furthermore, the guiding device includes a guide frame, a guide groove, and a slider.

[0012] This application utilizes the synergistic action of components such as a float, counterweight, connecting rod, and rotating ball to automatically adjust the opening and closing of the drain outlet according to water level changes, eliminating the need for manual intervention and significantly improving the automation of the drainage process. When the water level rises, the float rises rapidly, driving the counterweight and lifting rod to move, allowing the drain outlet to quickly connect with the drainage cavity for efficient drainage.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0022] Please see the appendix Figure 1-5 An automatic drainage device for compressed air system pipelines includes a drainage tank 1, an inlet pipe 2, a float 3, a fixed base 4, a rotating ball 5, a connecting rod 6, a guide device, a drainage channel 7, a lifting rod 8, a drain outlet 9, a limiting device, and a counterweight device. The inlet pipe 2 is located on one side of the drainage tank 1, the drainage channel 7 is located on the lower side of the drainage tank 1, the lifting rod 8 is slidably disposed within the drainage channel 7, the drain outlet 9 is opened on the lifting rod 8, the limiting device is located on the lower side of the lifting rod 8, the counterweight device is located on the top of the lifting rod 8, the guide device is located within the drainage tank 1, the fixed base 4 is respectively disposed on the counterweight device and the float 3, the rotating balls 5 are rotatably disposed on the fixed base 4, and the connecting rod 6 is disposed between the two rotating balls 5.

[0023] Using the above technical solution, the core of the automatic drainage device for compressed air system pipelines in this application lies in using water level changes to control drainage. When the condensate in the compressed air pipeline flows into the drainage tank 1 through the inlet pipe 2, the water level in the drainage tank 1 rises, and the float 3 rises accordingly. The float 3 and the counterweight ball 11 are connected as a whole through the connecting rod 6, the rotating ball 5, and the connecting rod 6. The rise of the float 3 will drive the entire counterweight device and the lifting rod 8 connected to it to rise. This upward movement causes the drain outlet 9 to gradually connect with the drainage cavity in the drainage channel 7, thereby achieving the drainage effect. When the water level drops, the float 3 also drops. Through the same connection mechanism, the counterweight device drops, and the lifting rod 8 also drops, closing the drain outlet 9 and stopping drainage. The limit device ensures that the lifting rod 8 moves within a specific range to prevent excessive lifting.

[0024] In detail, the counterweight ball 11 and the float ball 3 are connected and fixed by the rotating ball 5 connected to it by the connecting rod 6. Since the rotating ball 5 can rotate 360 ​​degrees in the fixed seat 4, when the float ball 3 rises and then drives the lifting rod 8 to rise together with the connecting rod 6, the rotating ball 5, and the fixed seat 4, the certain rotation amplitude of the rotating ball 5 can prevent the lifting rod 8 from getting stuck in the drainage channel 7 due to the angle limitation when the float ball 3 drives the counterweight ball 11 to rise.

[0025] In some embodiments, the counterweight device includes a fixed rod 10 and a counterweight ball 11. The fixed rod 10 is disposed at the top of the lifting rod 8, the counterweight ball 11 is disposed at the top of the fixed rod 10, and the connecting rod 6 connects the counterweight ball 11 and the float 3.

[0026] Using the above technical solution, the fixed rod 10 is firmly connected to the top of the lifting rod 8, serving as a support and force transmission mechanism. The counterweight ball 11 is located at the top of the fixed rod 10, increasing the weight of the entire counterweight device and enabling it to move more stably with the rise and fall of the float ball 3. When the water level in the drainage tank 1 rises, the float ball 3 rises accordingly. Since the float ball 3 and the counterweight device are tightly connected through the connecting rod 6 and the rotating ball 5, the upward movement of the float ball 3 directly drives the counterweight ball 11 and the lifting rod 8 to rise as a whole, thereby gradually connecting the drainage outlet 9 with the drainage channel 7. The cavities are interconnected, allowing water to flow out and achieving a drainage effect. Conversely, when the water level drops, the float 3 also drops. Through the transmission action of the connecting rod 6 and the rotating ball 5, the counterweight device drops as a whole, the lifting rod 8 also drops, and the drain outlet 9 gradually closes, stopping the drainage. In this way, the entire drainage device can automatically adjust the opening and closing state of the drain outlet 9 according to the change of water level, thereby effectively controlling the drainage process, keeping the compressed air system dry and stable. At the same time, the addition of the counterweight device also improves the stability and reliability of the device, making it better adaptable to various working environments and conditions.

[0027] In some embodiments, the guiding device includes a guide frame 12, a guide groove 13, and a slider 14. The guide frame 12 is disposed inside the drainage tank 1, the guide groove 13 is opened on both sides of the guide frame 12, and the slider 14 is disposed on both sides of the lifting rod 8. The slider 14 slides in the guide groove 13.

[0028] By adopting the above technical solution, the guide device ensures the stable sliding of the lifting rod 8 in the drainage channel 7. The guide frame 12 serves as a support structure, and the guide groove 13 provides a clear sliding path for the slider 14. The slider 14 is fixed on both sides of the lifting rod 8 and slides in the guide groove 13 as the lifting rod 8 rises and falls. This not only improves the stability of the lifting rod 8, but also ensures the accuracy and reliability of the opening and closing of the drain outlet 9, preventing poor drainage or device damage caused by shaking or displacement.

[0029] In some embodiments, the limiting device includes limiting blocks 15, which are symmetrically arranged on both sides of the lifting rod 8 and engage with the bottom of the drainage channel 7. The limiting device, through the design of the limiting blocks 15, restricts the range of movement of the lifting rod 8 within the drainage channel 7. When the lifting rod 8 reaches its highest point, i.e., when the drain outlet 9 is fully open, the limiting blocks 15 contact the bottom of the drainage channel 7, and the drainage pipe limits the limiting blocks 15, preventing the lifting rod 8 from continuing to rise, thereby ensuring smooth drainage.

[0030] In some embodiments, the drainage channel 7 has a drainage cavity, and the drainage channel 7 is disposed through the drainage tank 1.

[0031] The drainage cavity in the drainage channel 7 is used to collect and discharge water flowing out through the drain outlet 9. The drainage channel 7 is installed through the drainage tank 1 to ensure that water can be smoothly discharged from the drainage tank 1 through the drain outlet 9 and the drainage cavity.

[0032] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
