[0016] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0017] like Figure 1-4 The synchronous backwashing structure of a feces and wastewater integrated lifting device shown in the figure comprises a water tank 1 and a tank cover 2 located on the top of the water tank 1, a wastewater input pipe 3 is installed on the outer wall of the water tank 1, a cutting device for cutting fibers and debris in the wastewater is installed inside the water tank 1, the wastewater transported by the wastewater input pipe 3 enters the water tank 1 after being processed by the cutting device, a pumping pump 4 for transporting the wastewater in the water tank 1 to the sewage pipe network is also installed inside the water tank 1, a backwashing pipe 5 is connected to the outlet of the pumping pump 4, and the backwashing pipe 5 extends along the inner wall of the water tank 1 to the inlet of the cutting device;

[0018] On the basis of the above, the wastewater input pipe 3 is located on the outer wall of the water tank 1 outside the cutting device, and the other end of the wastewater input pipe 3 is set at the fecal wastewater of the toilet. When working, the wastewater input pipe 3 transports wastewater containing sludge, feces and other substances to the cutting device in the water tank 1. The cutting device performs crushing cutting on the fiber tissue in the wastewater so that the treated wastewater does not contain large particles and long fiber impurities. The treated wastewater accumulates at the bottom of the water tank 1 and is transported to the sewage network through the operation of the pumping pump 4.

[0019] Furthermore, during the process of the pumping pump 4 transporting the treated wastewater, part of the wastewater flows back along the backwash pipe 5 to the fecal sludge deposition area at the inlet of the cutting device, flushing the solid waste in the deposition area to avoid some solid waste from accumulating at the inlet of the cutting device.

[0020] The cutting device comprises a cutting box 6 located inside the water tank 1, wherein the cutting box 6 is hollow inside and has open front and rear sides, and a plurality of cutting wheels 7 are installed inside the cutting box 6;

[0021] A support frame 8 is installed at the bottom of the cutting box 6, and a motor 9 for driving the cutting wheel 7 is installed on the top of the cutting box 6. The top of the cutting box 6 is embedded on the box cover 2, and the motor 9 is located above the box cover 2;

[0022] Furthermore, the wastewater inlet pipe 3 transports the wastewater to the front side of the cutting box 6, and the wastewater and solid waste fall into the inside of the cutting box 6. The motor 9 drives several groups of cutting wheels 7 to rotate inside the cutting box 6, and the solid waste and long-fiber impurities are cut and processed by the several groups of cutting wheels 7 for crushing. The treated wastewater is accumulated at the bottom of the water tank 1 due to gravity.

[0023] Furthermore, a water outlet pipe 10 is installed at the outlet of the pumping pump 4, and the water outlet pipe 10 extends upward through the box cover 2 to the top of the box cover 2;

[0024] The pumping pump 4 pumps the wastewater accumulated at the bottom of the water tank 1 outwards and delivers it to the external sewage network through the outlet pipe 10;

[0025] There may be multiple pumping pumps 4, and multiple water outlet pipes 10 may be controlled and connected via valves to centrally transport wastewater to an external sewage pipe network.

[0026] One end of the backwash pipe 5 is connected to the water outlet pipe 10, and the other end of the backwash pipe 5 is bent to the front side of the cutting box 6 and extends to one side of the cutting wheel 7;

[0027] On the basis of the above, the backwash pipe 5 is connected to the outlet pipe 10. When the pumping pump 4 discharges wastewater, a part of the wastewater returns along the pipeline into the backwash pipe 5, and then is transported along the backwash pipe 5 to the front side of the cutting box 6, that is, the feces sludge deposition area at the wastewater inlet. The wastewater transported by the pumping pump 4 is a high-pressure water body. After the energy conversion of the pump, the wastewater pressure increases (normal pressure is about 0.3-0.4MPa), and it has the kinetic energy to flush feces and sludge, and can flush the feces sludge deposition area, flushing away the sediment to avoid accumulation.

[0028] An induction switch 11 is installed on the wastewater inlet pipe 3 .

[0029] When the wastewater in the toilet pipe network is transported from the wastewater input pipe 3 to the inside of the water tank 1, the induction switch 11 will sense the input of the wastewater, and at this time, the motor 9 and the pumping pump 4 are started at the same time. After the wastewater enters the tank, it is cut by the cutting device, and then the wastewater is transported from the pumping pump 4 and the outlet pipe 10 to the external sewage pipe network, and part of the wastewater flows back from the backwash pipe 5 to the fecal sludge deposition area for flushing, realizing the automatic and synchronous backwashing function, without the need for regular shutdown, and manually connected to tap water, or directly connected to external tap water for flushing and cleaning, saving labor costs and reducing tap water consumption. The economic benefits are very obvious.

[0030] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
