[0032] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.

[0033] Example 1

[0034] like Figure 2 As shown, an embodiment of the utility model provides a water treatment station outlet pipe cleaning device, including an aeration tower 1, a water pump and a treatment water tank, wherein the water inlet of the aeration tower 1 is connected to the underground water pipe, the drainage valve 1.1 of the aeration tower 1 is connected to the drainage pipe 4, and the drainage pipe 4 is connected to the first branch pipe 5.1 and the second branch pipe 5.2 respectively; the first branch pipe 5.1 is connected to the first valve 6.1, the first water pump 2.1 and the first treatment water tank 3.1 in sequence, and the second branch pipe 5.2 is connected to the second valve 6.2, the second water pump 2.2 and the second treatment water tank 3.2 in sequence, and the water treatment station outlet pipe cleaning device includes a three-way connecting pipe and a flange cover arranged at the turning radius of the outlet pipe.

[0035] Specifically, a first three-way connecting pipe 9.1 and a first flange cover 10.1 are provided at the turning radius of the first branch pipe 5.1. The first three-way connecting pipe 9.1 is connected in series with the first branch pipe 5.1 through a first port and a second port, specifically by welding or threaded connection. The third port of the first three-way connecting pipe 9.1 is detachably threadedly connected to the first flange cover 10.1. The first branch pipe 5.1 is also provided with a first pressure gauge 7.1 and a first flow meter 8.1.

[0036] Similarly, a second three-way connecting pipe 9.2 and a second flange cover 10.2 are provided at the turning radius of the second branch pipe 5.2. The second three-way connecting pipe 9.2 is connected in series with the second branch pipe 5.2 through the first port and the second port, specifically by welding or threaded connection. The third port of the second three-way connecting pipe 9.2 is detachably threadedly connected to the second flange cover 10.2. The second branch pipe 5.2 is also provided with a second pressure gauge 7.2 and a second flow meter 8.2.

[0037] At the same time, in the embodiment of the utility model, the drainage pipe 4, the first branch pipe 5.1, the second branch pipe 5.2, the first three-way connecting pipe 9.1 and the first flange cover 10.1, and the second three-way connecting pipe 9.2 and the second flange cover 10.2 are all made of UPVC material, which has the advantages of strong corrosion resistance, smooth inner and outer surfaces, small fluid resistance, high mechanical strength, etc. At the same time, since the inner wall of the pipe is smooth, scale and high-viscosity dirt in the pipe can be prevented from forming wall hanging in the pipe, so as to avoid pollution and blockage of the pipe at the turning radius of the pipe.

[0038] During operation, when the pressure and flow rate detected by the pressure gauge and flow meter are small, it indicates that the corresponding branch pipe may be blocked and needs to be cleaned. At this time, close the drain valve 1.1, the first valve 6.1 and the second valve 6.2, and only need to remove the flange cover on the corresponding pipeline to clean the scale in the pipeline. There is no need to dismantle the entire outlet pipeline (drainage pipeline 4 + two branch pipes 5.1, 5.2). The cleaning and maintenance work is more convenient and efficient, and timely cleaning can effectively extend the service life of the pipeline and reduce the cost of pipeline replacement.

[0039] At the same time, if the first port and the second port of the first three-way connecting pipe 9.1 are threadedly connected to the first branch pipe 5.1, and the first port and the second port of the second three-way connecting pipe 9.2 are threadedly connected to the second branch pipe 5.2, when cleaning the pipe, when the blockage is serious or the blocked part extends for a long time and is not easy to clean, the entire three-way connecting pipe can also be disassembled for more thorough cleaning and maintenance. If necessary, the three-way connecting pipe corroded by scale can be directly replaced. Compared with disassembling the entire outlet pipe for cleaning and maintenance, disassembling the three-way connecting pipe is more time-saving, labor-saving and convenient, and the cost of replacing the pipe is relatively low.

[0040] Example 2

[0041] The present invention has made the following improvements on the basis of the first embodiment:

[0042] like Figure 3 As shown, a first pneumatic pipe vibrator 11.1 is provided on the first branch pipe 5.1 near the first three-way connecting pipe 9.1, and a second pneumatic pipe vibrator 11.2 is provided on the second branch pipe 5.2 near the second three-way connecting pipe 9.2;

[0043] The first branch pipe 5.1 and the second branch pipe 5.2 between the first pneumatic pipe vibrator 11.1 and the second pneumatic pipe vibrator 11.2 are connected to the third water pump 16 through the first flushing pipe 15.1 and the second flushing pipe 15.2 respectively, and the third water pump 16 is connected to one of the treatment water tanks, such as the first treatment water tank 3.1, through the third flushing pipe 15.3.

[0044] Meanwhile, the first flushing pipeline 15.1, the second flushing pipeline 15.2 and the third flushing pipeline 15.3 are respectively provided with a third valve 14.1, a fourth valve 14.2 and a fifth valve 14.3.

[0045] During operation, when the pressure and flow rate detected by the pressure gauge and flow meter are small, it indicates that the corresponding branch pipe may be blocked and needs to be cleaned. At this time, the pneumatic pipe vibrator can be turned on for a certain period of time (such as 1-2 minutes) for preliminary cleaning. If the monitored pressure and flow rate return to normal, there is no need to remove the flange cover and continue normal operation;

[0046] If the monitored pressure and flow still cannot return to normal, close the drain valve 1.1, the first valve 6.1 and the second valve 6.2, open the fifth valve 14.3 and the third valve 14.1 and / or the fourth valve 14.2 on the corresponding flushing pipeline, remove the flange cover on the corresponding pipeline, pump cleaning water into the pipeline through the third water pump 16, keep the first pneumatic pipeline vibrator 11.1 and / or the second pneumatic pipeline vibrator 11.2 running, perform pipeline vibration cleaning, and discharge the cleaning sewage from the third port of the three-way connecting pipeline until the cleaning water is clean and the cleaning is completed.

[0047] The above cleaning process first uses a pneumatic pipe vibrator to perform preliminary cleaning of pipe blockages. When the monitored pressure and flow still cannot return to normal, a special long-term vibration cleaning is performed in combination with flushing the pipe, and the cleaned sewage is discharged. This process can further improve the cleaning and maintenance efficiency, and directly uses a pneumatic pipe vibrator to clean pipe blockages, eliminating the trouble of manual cleaning, and cleaning is more efficient and convenient.

[0048] Example 3

[0049] The present utility model embodiment is based on the embodiment 2 with the following improvements:

[0050] like Figure 4 As shown, a dosing pipe 17 is connected to the third flushing pipe 15.3 between the third water pump 16 and the fifth valve 14.3. The dosing pipe 17 is connected to the dosing tank 12. The dosing tank 12 contains a cleaning agent. A dosing valve 13 is provided on the dosing pipe 17.

[0051] During operation, when the pressure and flow rate detected by the pressure gauge and flow meter are small, it indicates that the corresponding branch pipeline may be blocked and needs to be cleaned. At this time, the drain valve 1.1, the first valve 6.1 and the second valve 6.2 can be closed first, the flange cover on the corresponding pipeline can be removed, the fifth valve 14.3 and the third valve 14.1 and / or the fourth valve 14.2 on the corresponding flushing pipeline can be opened, and cleaning water can be pumped into the pipeline through the third water pump 16; at the same time, the first pneumatic pipeline vibrator 11.1 and / or the second pneumatic pipeline vibrator 11.2 on the corresponding branch pipeline can be started to perform pipeline vibration cleaning;

[0052] During the vibration cleaning process, open the dosing valve 13 on the dosing pipe 17 to pump the cleaning agent in the dosing tank 12 into the branch pipe to be cleaned. After a certain period of vibration cleaning, close the dosing valve 13 and then vibrate and flush the pipe with clean water until the cleaning water is clean and the cleaning is completed.

[0053] In the above cleaning process, a cleaning agent is added during the vibration cleaning process, which has a better effect and higher cleaning efficiency than directly using clean water for vibration cleaning.

[0054] The above description is only an embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement and improvement made within the scope of application of the present invention shall be included in the protection scope of the present invention.
