Technical Field

[0005] After searching, the Chinese patent application number CN202022615803.1 discloses a backwash sewage treatment device. The utility model uses the structure of the large and small ends of the cam to push the lifting rod to lift and lower, so that the vibration plate vibrates the first filter screen, effectively preventing the first filter screen from being blocked. In addition, a screw slider structure is arranged between the first filter screen and the second filter screen to drive the fan to move the second filter screen to blow impurities, effectively preventing the second filter screen from being blocked.

Two third motors 25 are fixedly connected to one side of the box body 1, and the output ends of the two third motors 25 are coaxially connected to the rotating blocks 26. The two filter screens 10 are quickly and slightly vibrated up and down by the two third motors 25 and the rotating blocks 26, so that impurities can be kept loose on the surface of the filter screen 10, so that the subsequent sewage treatment maintains a good filtering effect and speed, and at the same time, the two filter screens 10 can be quickly taken out from the inside of the box body 1, which is convenient for cleaning the filter screens 10.

[0042] Reference Figure 5 As shown, specifically, the other sides of the two filters 10 are fixedly connected with second rotating rods 13, and multiple second rotating rods 13 are symmetrically distributed on the other sides of the two filters 10, so that the two filters 10 can maintain a stable connection with the slots 3 on the inner wall of the box body 1.

[0043] Reference Figure 3 As shown, specifically, an inclined baffle 14 is fixedly connected to the bottom side of the interior of the box body 1, a plurality of baffle bars 15 are fixedly connected to the top of the inclined baffle plate 14, a first motor 16 is fixedly connected to the rear side of the box body 1, and a cleaning roller 17 is coaxially connected to the output end of the first motor 16 to further statically filter the treated water and then quickly transport it out through the cleaning roller 17.

[0044] Reference Figure 6 As shown, specifically, a fixing ring 18 is fixedly connected to the other side of the box body 1, a liquid collecting barrel 19 is fixedly connected inside the fixing ring 18, a second motor 20 is fixedly connected to the top of the liquid collecting barrel 19, a stirring rod 21 is coaxially connected to the output end of the second motor 20, and a water inlet pipe 22 is fixedly connected to the top of the second motor 20, so as to fully stir and disperse the sewage to prevent larger impurities from entering the interior of the box body 1 and affecting the sewage treatment effect.

[0046] Working principle of the utility model: when treating sewage by backwashing the sewage tank, water is first put into the liquid collecting barrel 19 through the water inlet pipe 22, and then the second motor 20 drives the two stirring rods 21 to rotate inside the liquid collecting barrel 19 to stir the sewage inside the liquid collecting barrel 19, so that the impurities in the sewage are stirred, and then the water pump 24 starts to operate, and the stirred water in the liquid collecting barrel 19 is transported to the inside of the box body 1 through the water outlet pipe 23.
