[0020] For example, Figs. 1-2As shown, an automatic dredging anaerobic water inlet pipe device, which mainly comprises a pipe body 1, a monitoring module 10, a dredging module 12 and a control module. A rotating filter crushing assembly is further arranged at the inlet of the pipe body 1, which comprises a spiral conveying rod 5 rotatably installed at the inlet of the pipe body 1, and the end of the spiral conveying rod 5 is connected with a crushing blade 16 through a linkage structure.

[0021] Specifically, the pipe body 1 is an anaerobic water inlet pipe, which is a conveying channel for sewage entering an anaerobic treatment unit, and is made of a corrosion-resistant and wear-resistant PE pipe to adapt to the corrosive environment of sewage.

[0022] The monitoring module 10 is installed on the pipe body 1 and is used for real-time monitoring of the pressure change of the inlet and outlet of the pipe to determine whether there is a sign of blockage. The monitoring module 10 comprises pressure sensors 14 installed at the inlet and outlet of the pipe body 1, which are used for monitoring the pressure in the pipe. When the pressure at the inlet abnormally rises, it may indicate that the pipe is blocked. A flow rate sensor 15 is installed at the end of the pipe body 1 and is used for detecting the water flow rate. A significant decrease in the water flow rate may also be a signal of blockage. A video monitoring device is provided at the inlet of the anaerobic pipe of the biochemical tank. A miniature camera is installed at a key position of the pipe to directly observe the water flow condition of the pipe.

[0023] The dredging module 12 is composed of a driving mechanism and a dredging tool. The driving mechanism is selected from an electric push rod, which can provide sufficient power to push the dredging tool to move in the pipe. The dredging tool comprises a dredging flexible shaft 13, a brush, a high-pressure water gun nozzle and the like. The dredging flexible shaft 13 is an encryption spring. When the monitoring module 10 detects a pipe blockage signal, the electric door is first opened, and then the driving mechanism drives the dredging tool to enter the pipe for dredging operation. The specific operation is that the spiral drill rod breaks and carries out the blockage by rotating drilling into the blockage; the brush can clean the impurities attached to the inner wall of the pipe; and the high-pressure water gun nozzle can use high-pressure water flow to impact the blockage to disperse and flush it away. The dredging module 12 is arranged in a branch pipe 11, which is obliquely arranged on the main pipe, and the outlet of the branch pipe 11 faces the water outlet of the main pipe.

[0024] Rotary filtering and crushing assembly: provided at the inlet of the pipeline body 1, comprising a spiral conveying rod 5 rotatably installed at the inlet of the pipeline body 1, the end of the spiral conveying rod 5 being connected to a crushing blade 16 through a linkage structure. The connecting pipeline body 1 comprises a vertically arranged water inlet pipe 2 and a horizontally arranged main pipeline; the rotary filtering and crushing assembly further comprises a filtering pipeline 3 arranged in the water inlet pipe 2, the filtering pipeline 3 being composed of a funnel-shaped water inlet section 4 and a straight pipeline section, the spiral conveying rod 5 being rotatably installed in the straight pipeline section along the length direction of the straight pipeline section; the linkage structure comprises a driving wheel 7 arranged at the bottom of the spiral conveying rod 5, a rotary rod 9 horizontally arranged and hung in the main pipeline, and a driven wheel 8 installed at the end of the rotary rod 9, the driven wheel 8 being engaged with the driving wheel 7, both the driven wheel 8 and the driving wheel 7 being conical gears, and the crushing blade 16 being installed on the rotary rod 9; a driven blade 17 is further installed on the rotary rod 9, under the action of the driven blade 17, the flowing sewage drives the crushing blade 16 to rotate, crushes the sundries, increases the passing property of the sewage, and further avoids the blocking condition.

[0025] The liquid inlet of the water inlet section 4 is provided with a filter plate 6, and the top of the spiral conveying rod 5 is movably connected to the filter plate 6 through a connecting rod. The sewage enters the water inlet section 4 through the filter plate 6, passes through the spiral conveying rod 5, drives the spiral conveying rod 5 to rotate, the spiral conveying rod 5 drives the driving wheel 7 at the bottom to rotate, the driving wheel 7 drives the driven wheel 8 to rotate, and further drives the rotary rod 9 and the crushing blade 16 to rotate, thereby performing dynamic filtering on the sewage.

[0026] Control module: as the core control unit of the entire device, it receives monitoring data from the monitoring module 10, and analyzes and judges the data according to the preset algorithm and threshold value. When it is judged that the pipeline is blocked, the control module issues an instruction to start the dredging module 12 to perform dredging work. At the same time, the control module can also monitor the dredging process, and timely adjust the dredging strategy according to the dredging effect, such as changing the working parameters of the dredging tool, prolonging the dredging time, etc. The control module is connected to the upper computer of the equipment through DP communication, and the operator can remotely understand the running condition of the device and the pipeline blockage dredging progress.

[0027] The working process of the device will be described in detail below with reference to the accompanying drawings in the embodiments.

When installing the dredging module 12, it is necessary to ensure that the driving mechanism is installed firmly, and the dredging tool can smoothly enter and exit the pipeline. The control module is installed at a position convenient for wiring and maintenance, and completes the communication connection configuration with the monitoring module 10, the dredging module 12 and external equipment.

[0030] 2. Operation monitoring:

[0031] During the normal operation of the sewage treatment system, the monitoring module 10 collects the water flow state and pressure change data in the pipeline in real time and transmits the data to the control module. The control module continuously analyzes the data to determine whether the pipeline is in a normal operation state.

[0032] 3. Blockage dredging:

[0033] When the monitoring module 10 detects a pipeline blockage signal and transmits it to the control module, the control module immediately starts the dredging module 12. According to the blockage condition, the appropriate dredging tool is executed, first the high-pressure water gun nozzle is used for impact; if there is no improvement, it is determined that the blockage is relatively hard, and the spiral drill rod is started for crushing. During the dredging process, the control module adjusts the dredging strategy in a timely manner according to the dredging effect until the pipeline is restored to smoothness.
