The lower side of the rubber plate 32 is in contact with the upper surface of the bottom plate 33 to avoid excessive water leakage. The filter screen 2 8 performs filtration again, and the filtered water flows out from the water outlet 5. The filtration of the double filter screens improves the effect of mud and water separation;

[0025] The scraper mechanism 2 is arranged on the upper surface of the support platform and inside the separation tank 1. The scraper mechanism 2 includes a motor 21, an anti-reversal assembly 22, a rotating shaft 23 and a scraper plate 24. The rotating shaft 23 is rotatably connected to the left side wall of the separation tank 1. A circular hole rotatably connected to the rotating shaft 23 is opened in the middle of the filter screen 7. Two groups of scraper plates 24 are arranged on the right side of the rotating shaft 23. The scraper plates 24 are respectively located on the left side of the filter screen 1 7 and the filter screen 2 8. The upper surface of the support platform is connected to the motor 21 by bolts. The output of the motor 21 The right side of the output shaft is fixedly connected to the left side of the rotating shaft 23. An anti-reversal component 22 is arranged on the left side of the rotating shaft 23. The anti-reversal component 22 is located between the motor 21 and the left side of the separation tank 1. The input end of the motor 21 is electrically connected to the output end of the single-chip microcomputer 4. When it is found that the filtering efficiency becomes low, the motor 21 is controlled to rotate by the single-chip microcomputer 4. The output shaft of the motor 21 drives the rotating shaft and the scraper 24 to rotate. The scraper 24 scrapes off the mud attached to the filter screen 1 7 and the filter screen 2 8, thereby extending the service life of the filter screen 1 7 and the filter screen 2 8.

[0026] The anti-reversal assembly 22 includes a block 221, a pawl 222 and a ratchet 223. The ratchet 223 is fixedly sleeved on the left side of the rotating shaft 23. The ratchet 223 is located between the motor 21 and the left side of the separation tank 1. The left side of the separation tank 1 is rotatably connected with the pawl 222 through a rotating rod. The ratchet 223 and the pawl 222 are matched. A block 221 is provided on the left side of the separation tank 1. The block 221 is located at the lower side of the pawl 222. The muddy water scouring the scraper 24 may cause the rotating shaft to reverse. When the ratchet 223 reverses, the pawl 222 blocks the ratchet teeth of the ratchet 223, and the rotating shaft cannot reverse, thereby avoiding the occurrence of reversal.

[0027] Mud cleaning mechanism 3: It is arranged at the lower end of the separation tank 1. The mud cleaning mechanism 3 includes an electric push rod 31, a rubber plate 32 and a bottom plate 33. The bottom plate 33 is slidably connected to the lower end of the separation tank 1. The electric push rod 31 is arranged on the upper surface of the right side of the lower edge of the separation tank 1. The front side of the extended end of the electric push rod 31 is fixedly connected to the rear side of the edge of the bottom plate 33. The rubber plate 32 is fixedly connected to the front, back, left and right sides of the lower end of the separation tank 1. The lower side of the rubber plate 32 is in contact with the upper surface of the bottom plate 33. The electric push rod 31 is arranged on the upper surface of the right side of the lower edge of the separation tank 1. The input end of 1 is electrically connected to the output end of the single-chip microcomputer 4. The mud cleaning mechanism 3 also includes an auxiliary rod 34, which is slidably connected to the slide seat at the lower end of the left side of the separation tank 1. The front side of the auxiliary rod 34 is fixedly connected to the rear side of the edge of the bottom plate 33. When too much mud accumulates, the pouring of mud and water is stopped, and the output end of the electric push rod 31 is extended through the single-chip microcomputer 4 to drive the bottom plate 33 to be pulled out. At the same time, the auxiliary rod 34 slides to the front side to prevent the bottom plate 33 from being offset and stuck, so that the mud is quickly cleaned out of the mud and water separator.

[0028] The single chip microcomputer 4 is also included. The single chip microcomputer 4 is arranged on the upper surface of the lower edge of the separation tank 1 . The input end of the single chip microcomputer 4 is electrically connected to an external power supply to control the motor 21 and the electric push rod 31 .

[0029] The working principle of a mud-water separator for domestic sewage treatment provided by the utility model is as follows: muddy water is poured into the separation tank 1 from the left side of the upper end of the separation tank 1, the filter screen 17 performs preliminary filtration, and the filtered mud and sand fall into the lower end of the separation tank 1. The lower side of the rubber plate 32 contacts the upper surface of the bottom plate 33 to avoid excessive water leakage. The filter screen 28 performs filtration again, and the filtered water flows out from the water outlet 5. The filtration of the double filter screens improves the effect of mud-water separation. During the filtration, mud adheres to the filter screen 1 7 and the filter screen 2 8, clogging the mesh and reducing the filtration efficiency. The filter screen is corroded for too long, reducing the service life of the filter screen 1 7 and the filter screen 2 8. When it is found that the filtration efficiency becomes low, the motor 21 is controlled to rotate by the single-chip microcomputer 4, and the motor 2 The output shaft drives the rotating shaft and the scraper blade 24 to rotate. The scraper blade 24 scrapes off the mud attached to the filter screen 1 7 and the filter screen 2 8 to extend the service life of the filter screen 1 7 and the filter screen 2 8. The mud and water washing the scraper blade 24 may cause the rotating shaft to reverse. When the ratchet 223 reverses, the pawl 222 gets stuck on the ratchet teeth of the ratchet 223, and the rotating shaft cannot reverse. Reversal avoids the occurrence of reversal. When too much mud accumulates, the pouring of mud and water is stopped. The output end of the electric push rod 31 is controlled by the single-chip microcomputer 4 to extend, driving the bottom plate 33 to be pulled out, and the auxiliary rod 34 slides to the front side at the same time to avoid the bottom plate 33 from being offset and stuck, and the mud is quickly cleaned out of the mud and water separator. After the cleaning is completed, the electric push rod 31 drives the bottom plate 33 to be retracted to continue the mud and water separation of sewage.

[0030] It is worth noting that the single chip microcomputer 4 disclosed in the above embodiment can use MCIMX515DJM8C, the motor 21 can use R37-11.83 / Y280-4 helical gear reduction motor, the electric push rod 31 can use BR50 electric push rod, and the single chip microcomputer 4 controls the motor 21 and the electric push rod 31 to work using methods commonly used in the prior art.

[0031] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
