The specific embodiments of the device will be described in detail below in combination with the drawings and part numbers.

[0025] As shown in Figure 1 , the overall assembly structure of the utility model is composed of a sedimentation structure 1, a separation structure 2 and a control structure 3, which realize the efficiency and convenience of sewage treatment through reasonable spatial layout. The sedimentation structure 1 is located at the bottom of the device, the separation structure 2 is fixedly arranged at the upper part of the sedimentation structure 1, and the control structure 3 is detachably installed in the middle part of the side wall of the separation structure 2. This upper and lower combination design not only saves the space occupied by the device, but also facilitates the maintenance and repair of each part by the operator. In practical application, sewage first enters the sedimentation structure 1 for preliminary treatment, then flows into the separation structure 2 for further separation, and finally realizes automatic drainage and monitoring through the control structure 3.

[0026] The specific structure of the sedimentation structure 1 is shown in Figure 2 , which comprises a sedimentation tank 11, a water inlet pipe 12, a sludge discharge port 13, a flow guide plate 14, a filter screen 15 and a water outlet 16. The sedimentation tank 11 is a rectangular box body, the top of which is provided with a water inlet, and the water inlet pipe 12 is fixedly connected to the water inlet for introducing the sewage to be treated into the sedimentation tank 11. The sludge discharge port 13 is arranged at the bottom of the sedimentation tank 11 near the left side, which is used for periodically discharging the sludge deposited. The flow guide plate 14 is arranged inside the sedimentation tank 11 below the water inlet pipe 12, which is used to guide the flow of sewage in a specific direction, thereby prolonging the residence time of sewage in the sedimentation tank 11 and improving the sedimentation effect. The filter screen 15 is fixedly arranged in the middle of the sedimentation tank 11, which is used to intercept larger suspended solids to prevent them from entering the subsequent separation structure 2. The water outlet 16 is arranged on the right side wall of the sedimentation tank 11 near the upper end, which is used to guide the sewage after preliminary sedimentation to the separation structure 2. In actual operation, the sewage enters the sedimentation tank 11 through the water inlet pipe 12 and forms a slow flow under the action of the flow guide plate 14, the larger particle solid substances gradually settle at the bottom of the sedimentation tank 11, and the smaller particle suspended solids are intercepted by the filter screen 15, and finally the relatively clear sewage flows into the separation structure 2 through the water outlet 16.

[0027] The specific structure of the separation structure 2 is shown in Figure 3As shown, its main components include separation cylinder 21, rotating shaft 22, drive motor 23, scraper assembly 24, sludge collecting tank 25 and drain pipe 26. Separation cylinder 21 is a cylindrical body, the bottom of which is fixedly connected with the top of sedimentation tank 11, ensuring that sewage can flow smoothly from sedimentation structure 1 into separation structure 2. Rotating shaft 22 is movably penetrated through the central axis of separation cylinder 21, one end of which is connected with drive motor 23 and the other end of which extends into the interior of separation cylinder 21. Drive motor 23 is fixedly arranged on the top of separation cylinder 21 and is used to drive rotating shaft 22 to rotate. Scraper assembly 24 is fixedly sleeved on the outer wall of rotating shaft 22 and is used to clean the impurities adhered to the inner wall of separation cylinder 21. Sludge collecting tank 25 is fixedly arranged on the inner wall of separation cylinder 21 close to the bottom and is used to collect the impurities scraped off by scraper assembly 24. Drain pipe 26 is fixedly connected with the right side wall of separation cylinder 21 close to the upper end and is used to discharge the treated clean water. In actual operation, drive motor 23 is started to drive rotating shaft 22 to rotate, which in turn drives scraper assembly 24 to rotate in separation cylinder 21. Scraper teeth set 242 on scraper assembly 24 scrapes the impurities adhered to the inner wall of separation cylinder 21 into sludge collecting tank 25, while the buffer action of elastic connecting member 243 protects the inner wall of separation cylinder 21 from being damaged. The clean water treated by separation is discharged through drain pipe 26, thus completing the further purification of sewage.

Key group 34 is symmetrically arranged at the two corner positions near the lower end of the front side wall of control box 31, including start key and stop key, respectively used for controlling the running and stopping of driving motor 23. Sensor module 35 is fixedly arranged on the inner wall of separation cylinder 21 and electrically connected with circuit board 32, for real-time monitoring of the liquid level height and water quality parameters in separation cylinder 21 and transmitting data to circuit board 32 for processing. Electromagnetic valve 36 is fixedly installed on drain pipe 26 and electrically connected with circuit board 32, for automatically controlling the opening and closing of drain pipe 26 according to the instruction of circuit board 32. In actual operation process, sensor module 35 continuously monitors the liquid level and water quality parameters in separation cylinder 21 and transmits data to circuit board 32 for analysis and processing. When the liquid level reaches the preset value or the water quality parameters meet the requirements, circuit board 32 sends an instruction to control electromagnetic valve 36 to open drain pipe 26, thereby realizing automatic drainage. In addition, operating personnel can manually control the start and stop of driving motor 23 through key group 34 to meet the needs under different working conditions.

Then, the driving motor 23 starts to drive the rotating shaft 22 to rotate, so that the scraper assembly 24 rotates in the separation cylinder 21. The scraper teeth group 242 on the scraper assembly 24 scrapes the impurities attached to the inner wall of the separation cylinder 21 into the sludge collecting tank 25, and at the same time, the elastic connecting piece 243 protects the inner wall of the separation cylinder 21 from being damaged by the buffering action. The clean water after separation treatment is discharged through the drain pipe 26. In this process, the sensor module 35 monitors the liquid level height and water quality parameters in the separation cylinder 21 in real time, and transmits data to the circuit board 32 for processing. When the liquid level reaches the preset value or the water quality parameters meet the requirements, the circuit board 32 sends an instruction to control the electromagnetic valve 36 to open the drain pipe 26, thereby realizing automatic drainage. In addition, operating personnel can manually control the start and stop of the driving motor 23 through the key group 34 to meet the needs under different working conditions.

[0030] The utility model discloses the advantages lie in through the up and down combination design of sedimentation structure 1 and separation structure 2, realized the grading treatment of sewage, improved the sewage treatment efficiency significantly. The rotary motion of scraper assembly 24 effectively cleaned the impurity attached in the inner wall of separation cylinder 21, avoided the cumbersome operation of manual cleaning in traditional equipment, and separation cylinder 21 inner wall was protected with the help of elastic connecting piece 243. Control structure 3 through sensor module 35 real -time monitoring the liquid level and water quality parameter in separation cylinder 21, combines electromagnetic valve 36 automatic control drainage, has guaranteed the accuracy and automation level of sewage treatment process. In conclusion, the utility model discloses sewage sedimentation and separation equipment through structure optimization and technical improvement, improved the efficiency and reliability of sewage treatment significantly, reduced the equipment maintenance cost, has higher practical value and popularization prospect
