[0029] See also Figure 1-6 ,The utility model provides a technical solution:

[0030] A sewage enclosed lifting device with pre-treatment backwashing, comprising a sewage tank 1, a filter box 2 is provided on the upper side of the sewage tank 1, an inlet pipe 3 is fixedly provided on the upper side of the filter box 2, and a sewage pipe 4 is fixedly provided on one side of the filter box 2, the other end of the sewage pipe 4 is connected to the sewage tank 1, a second filter screen 20 is provided between the filter box 2 and the sewage pipe 4, and a sewage pipe 5 is fixedly provided on the other side of the filter box 2, a collection box 6 is fixedly provided on the outer end of the sewage pipe 5, a mounting pipe 7 is fixedly provided on the lower side of the collection box 6, and the other end of the mounting pipe 7 is connected to Sewage tank 1, and a rotating rod 13 is rotatably provided inside the mounting pipe 7, a water wheel 14 is fixedly provided at one end of the rotating rod 13, and the other end of the rotating rod 13 movably passes through the collection box 6 and extends to the inside, the other end of the rotating rod 13 is located at the inner part of the collection box 6 and is fixedly provided with a crushing knife group 15, and a first processing mechanism 11 is provided inside the filter box 2. When discharging sewage and debris, the water wheel 14 rotates through the impact force of the water flow, thereby driving the crushing knife group 15 to rotate, which is more energy-saving while facilitating the crushing of debris.

[0031] Specifically, a sewage pump 8 is fixedly provided on the outside of the sewage tank 1, and a water pumping pipe 9 is fixedly provided on one side of the sewage pump 8. The water pumping pipe 9 passes through the sewage tank 1 and extends to the inside, and a drain pipe 10 is fixedly provided on the other side of the sewage pump 8. The drain pipe 10 passes through the mounting pipe 7 and extends to the inside. The sewage pump 8 is installed on the outside of the sewage tank 1 and discharges sewage through the water pumping pipe 9 and the drain pipe 10 to avoid rust and corrosion caused by the sewage pump 8 being immersed in the sewage tank 1 for a long time.

[0032] Furthermore, a discharge pipe 12 is fixedly provided on the outer side of the collection box 6, which is located on the upper side of the crushing knife group 15. When the stains are discharged through the discharge pipe 12, the debris in the collection box 6 can be easily taken out, thereby improving the cleaning effect of the debris.

[0033] It is worth mentioning that a first filter screen 16 is fixedly provided between the collection box 6 and the mounting pipe 7. The provision of the first filter screen 16 facilitates filtering and collecting debris and facilitates the discharge of the debris.

[0034] It is worth noting that an overflow pipe 17 is fixedly provided on the lower side of the sewage pipe 5, and the other end of the overflow pipe 17 is connected to the sewage tank 1. By setting the overflow pipe 17, it is convenient for the filtered debris to enter the sewage pipe 5, and a small amount of water inside is discharged into the sewage tank 1, thereby further improving the solid-liquid separation effect of the dirt.

[0035] In addition, the first processing mechanism 11 includes a mounting cylinder 18 rotatably arranged on the inner side of the filter box 2, and a connecting rod 181 is movably inserted into the inner side of the mounting cylinder 18. The connecting rod 181 movably passes through the mounting cylinder 18 and extends to the outside, and the outer end of the connecting rod 181 is located on the outer side of the mounting cylinder 18 and is fixedly connected to the crushing knife group 2 19. A spring 182 is provided on the inner side of the mounting cylinder 18, one end of the spring 182 is connected to the mounting cylinder 18, and the other end of the spring 182 is connected to the connecting rod 181. Two groups of limit blocks 183 are fixedly provided on the outer side of the connecting rod 181, and two groups of limit grooves 184 for docking the limit blocks 183 are opened on the inner side of the mounting cylinder 18. Motor 21, the power end of motor 21 moves through the filter box 2 and is fixedly connected to the mounting cylinder 18. Motor 21 is controlled by a PLC controller, and the specific working time can be conveniently set and controlled. When the stains enter the filter box 2, they can drive the crushing knife group 2 19 and the connecting rod 181 to move downward. When the connecting rod 181 moves downward, it squeezes the spring 182 in the mounting cylinder 18, causing the spring 182 to deform. Subsequently, the elastic potential energy of the spring 182 is released, which can drive the connecting rod 181 and the crushing knife group 2 19 to move upward, so that the crushing knife group 2 19 can move up and down while rotating, further improving the crushing effect of the debris.

[0036] It must be said that both the sewage pipe 4 and the sewage pipe 5 are provided with a check valve 22 inside. The provision of the check valve 22 can prevent the backflow of the sewage when the sewage is discharged from the sewage tank 1 .

[0037] Working principle: First, the dirt enters the filter box 2 through the inlet pipe 3, and the dirt is filtered through the second filter screen 20 in the filter box 2. The sewage enters the sewage tank 1 through the sewage pipe 4, and the debris enters the collection box 6 through the sewage pipe 5. At the same time, when the dirt enters the filter box 2, the pressure sensor in the filter box 2 monitors the pressure and transmits the information to the PLC controller. Then the PLC controller starts the motor 21 to drive the installation cylinder 18 and the crushing knife group 2 19 to rotate, which can crush the debris entering the filter box 2. When the sewage collected in the sewage tank 1 reaches the set value The liquid level sensor in the sewage tank 1 transmits the information to the PLC controller, and then the PLC controller starts the sewage pump 8. The sewage pump 8 pumps the sewage in the sewage tank 1 into the installation pipe 7 through the suction pipe 9 and the drainage pipe 10. The sewage enters the collection box 6 through the installation pipe 7 and is finally discharged to the septic tank or the urban sewage network through the discharge pipe 12. At the same time, when the sewage enters the installation pipe 7, it can drive the water wheel 14 to rotate. The rotation of the water wheel 14 drives the rotating rod 13 and the crushing knife group 15 to rotate. The crushing knife group 15 can crush the debris in the collection box 6 to avoid blockage.
