[0032] One end of air pressure condensate intake pipe 2000 is inserted into receiving cavity 1100 through first water inlet 1200;

[0033] Second communication port 3300 and drainage port 3200 are set in the side wall of drainage tank 3000, drainage port 3200 and second communication port 3300 are close to the bottom of drainage tank 3000, second blow-off port 3400 is set in the bottom of drainage tank 3000, drainage cavity 3100 is set in drainage tank 3000, mounting cylinder base 3500 is set in the bottom of drainage cavity 3100, the inner cavity of mounting cylinder base 3500 is hollow, the inner cavity of mounting cylinder base 3500 is communicated with second blow-off port 3400, first connecting port 3510 is set in the side wall of mounting cylinder base 3500, and first connecting port 3510 is close to second communication port 3300;

[0034] Communication component 4000 includes first communication pipe 4100 and second communication pipe 4200, one end of first communication pipe 4100 is inserted into receiving cavity 1100 through first communication port 1400, the other end of first communication pipe 4100 is communicated with first connecting port 3510 through second communication port 3300, one end of second communication pipe 4200 is connected with one end of first communication pipe 4100 vertically;

[0035] The filter assembly 5000 comprises a filter screen cylinder 5100 and a limiting flange cover 5200, the sidewall of the filter screen cylinder 5100 is provided with a second connecting port 5110, the filter screen cylinder 5100 is arranged in the inner cavity of the mounting cylinder seat 3500, and the second connecting port 5110 is coincided with the first connecting port 3510, the limiting flange cover 5200 is provided with a limiting groove 5210, the limiting groove 5210 is matched with the bottom of the filter screen cylinder 5100, the bottom of the filter screen cylinder 5100 is in an open shape, the top of the filter screen cylinder 5100 is in a closed shape, and the limiting flange cover 5200 is bolted on the second blowdown port 3400;

[0036] Wherein, when the user uses the drainage device for compressed air pipe network to drain the condensed water in the compressed air pipe network, one end of the air compression condensed water inlet pipe 2000 extends into the receiving cavity 1100 through the first water inlet 1200, and the other end of the air compression condensed water inlet pipe 2000 is communicated with the compressed air pipe network, so that the compressed air in the compressed air pipe network carries the condensed water and the impurities in the compressed air into the receiving cavity 1100 through the air compression condensed water inlet pipe 2000, and the impurities are deposited at the bottom of the receiving cavity 1100, at this time, the first blowdown port 1300 is in a closed state, and the condensed water slowly accumulates in the receiving cavity 1100, so that the condensed water level slowly rises, until the condensed water level height exceeds the height of the other end of the second communication pipe 4200, at this time, the compressed air press the condensed water into the filter screen cylinder 5100 arranged in the inner cavity of the mounting cylinder seat 3500 through the second communication pipe 4200 and the first communication pipe 4100, at this time, the filter screen cylinder 5100 performs secondary filtration on the inflowing condensed water, and the impurities are intercepted in the filter screen cylinder 5100, and the filtered condensed water is first stored in the inner cavity of the mounting cylinder seat 3500, when the condensed water level height is lower than the height of the other end of the second communication pipe 4200, the condensed water will no longer flow into the inner cavity of the mounting cylinder seat 3500, and needs to wait for the next time the condensed water level height exceeds the height of the other end of the second communication pipe 4200, in this process, the first communication pipe 4100 and the second communication pipe 4200 contain condensed water, forming a water seal, thereby preventing the compressed air in the receiving cavity 1100 from flowing into the drainage cavity 3100 and being drained by the drainage;

[0037] After the above-mentioned multiple steps, the condensed water is filled in the inner cavity of the mounting cylinder seat 3500 and then flows into the drainage cavity 3100, so that the condensed water flowing into the drainage cavity 3100 is directly drained by the drainage port 3200;

[0038] After prolonged use, users need to clean the impurities in the receiving chamber 1100 and the drain chamber 3100 in a timely manner to prevent the impurities from settling too high. First, the user closes the air compressor condensate inlet pipe 2000, and then opens the first drain port 1300 of the receiving tank 1000. The impurities deposited at the bottom of the receiving chamber 1100 are discharged through the first drain port 1300. After the receiving tank 1000 is drained, the user removes the limiting flange cover 5200, then pulls out the filter screen cylinder 5100 and rinses it separately. After cleaning the filter screen cylinder 5100, the user puts the filter screen cylinder 5100 into the inner cavity of the mounting base 3500 and reinstalls the limiting flange cover 5200 back into the second drain port 3400, ensuring that the limiting groove 5210 fits with the top of the filter screen cylinder 5100, thereby fixing the filter screen cylinder 5100 and completing the cleaning process to avoid condensate drainage failure.

[0039] Preferably, such as Figure 2 As shown, a ramp is provided at the bottom of the receiving cavity 1100. This facilitates the accumulation of impurities at the first drain outlet 1300.

[0040] Furthermore, as shown in the figure, multiple mounting grooves 3520 are formed in the inner cavity of the mounting base 3500, and multiple sliders 5120 are provided on the outer wall of the filter cylinder 5100. The sliders 5120 cooperate with the mounting grooves 3520. Multiple filter holes 5130 are provided on both the outer wall and the bottom of the filter cylinder 5100. There is a gap between the outer wall of the filter cylinder 5100 and the inner wall of the mounting base 3500. The sliders 5120 cooperate with the mounting grooves 3520 to assist in positioning the filter cylinder 5100. At the same time, the diameter of the filter holes 5130 is 1mm, which can effectively filter blocky impurities and dust particles, so that blocky impurities and dust particles are always retained inside the filter cylinder 5100.

[0041] Furthermore, such as Figure 2 and Figure 3 As shown, the drainage device for the compressed air pipeline network also includes a drain pipe 5220 and a drain valve. The drain pipe 5220 is located at the center of the limiting flange cover 5200. One end of the drain pipe 5220 is connected to the drainage chamber 3100, and the other end of the drain pipe 5220 is equipped with a drain valve. When cleaning the drainage tank 3000, directly disassembling the limiting flange cover 5200 can easily cause water splashing and wet the disassembly personnel. Therefore, by setting up the drain pipe 5220 and the drain valve, when cleaning the filter cylinder 5100 inside the drainage tank 3000, the drain valve is opened first to remove the water or some fluid impurities present in the filter cylinder 5100, making it easier for the disassembly personnel to disassemble later, thereby avoiding wetting the disassembly personnel.

[0042] Furthermore, such as Figure 2 and Figure 3As shown, the drainage device for compressed air pipe network further comprises a limiting pipe 6000, one end of the limiting pipe 6000 is provided with an internal thread, the other end of the first communication pipe 4100 is provided with an external thread, the limiting pipe 6000 is arranged in the inner cavity of the mounting cylinder seat 3500, and the limiting pipe 6000 is in threaded cooperation with the other end of the first communication pipe 4100. By arranging the limiting pipe 6000, it is ensured that the other end of the first communication pipe 4100 extends into the filter screen cylinder 5100, and the filter screen cylinder 5100 is assisted in positioning, so that the first connecting port 3510 and the second connecting port 5110 coincide.

[0043] Further, the drainage device for compressed air pipe network further comprises control valves, and the control valves control the air compressor condensate water inlet pipe 2000 and the drainage port 3200. Users can control the compressed air pipe network through the control valves, so that the cleaning work can be smoothly carried out.
