The large-scale construction of sewage treatment plants has greatly improved the urban sewage treatment capacity. The role of septic tanks in urban sewage treatment and urban water environment protection has been significantly weakened, and its existence will also bring many problems. At present, Shanghai, Guangzhou, Hangzhou, Sichuan, Shandong and other places have clearly proposed relevant regulations to cancel septic tanks in newly built areas. However, since there are many large particles in fecal sewage, if it is allowed to enter the pipeline directly after the septic tank is cancelled, it is easy to cause pipeline blockage and affect the urban environmental sanitation and safety.

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a structural schematic diagram of the present invention.

[0017] Figure 2 yes Figure 1 AA view. DETAILED DESCRIPTION

[0018] The following is a detailed description of an embodiment of the present invention in conjunction with the accompanying drawings. This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation method and a specific operation process are given, but the protection scope of the present invention is not limited to the following embodiment.

[0019] like Figure 1 , 2 As shown, the cyclone crushing and lifting integrated device for sewage pipe network described in the present invention comprises a tank body 1, wherein a sewage collecting chamber 2 and a sewage discharging chamber 3 are formed by a partition plate in the tank body 1, wherein the sewage collecting chamber 2 is large at the top and small at the bottom, and a water inlet 4 is provided at the top, which can be connected to the sewage outlet pipe or the community drainage main pipe, and a cyclone crushing and lifting mechanism is installed at the bottom, which is used to grind and crush large particles of debris in the sewage; a connecting port is provided at the bottom of the sewage collecting chamber 2 and the sewage discharging chamber 3, and a drainage port is provided at the top of the sewage discharging chamber 3, which is used to connect to the municipal sewage pipe network. When the sewage of the residents enters the sewage collecting chamber 2, the large particles of debris therein are ground and crushed by the cyclone crushing and lifting mechanism, and then enter the sewage discharging chamber 3 and are discharged into the municipal sewage pipe network.

[0020] The tank body 1 is usually made of corrosion-resistant stainless steel or fiberglass. A liquid level meter 5 is installed on one side of the sewage collection chamber 2 of the tank body 1 to monitor the liquid level and adjust the processing capacity of the system. In order to deal with system failures, the sewage collection chamber 2 is also connected to an accident overflow pipe 6, which can directly discharge sewage into the municipal sewage network to ensure system safety.

[0021] The above-mentioned cyclone crushing and lifting mechanism uses the motor 7.1 installed on the top of the tank body 1 as a power source, and the rotating shaft 7.2 connected to the motor 7.1 extends downward into the sewage collecting chamber 2. The rotating shaft 7.2 is equipped with a grinding and crushing disc 7.3 and a rotating and lifting impeller 7.4 located below the water inlet 4, wherein the grinding and crushing disc 7.3 is located above the rotating and lifting impeller 7.4, and the grinding and crushing disc 7.3 is arranged in three levels, including a first disc 7.3a, a second disc 7.3b and a third disc 7.3c installed on the rotating shaft 7.2 from top to bottom, and each disc is provided with a grinding hole and a stirring knife. When the motor 7.1 is running and drives the rotating shaft 7.2 and the grinding and crushing disc 7.3 to rotate at high speed, the large particles of debris suspended above the sewage collection chamber 2 are accelerated into the grinding and crushing disc 7.3 under the vacuum formed by the initial operation, and pass through the first disc 7.3a, the second disc 7.3b, and the third disc 7.3c from top to bottom, and are continuously cut, collided and rubbed, so that the particle size of the impurities is continuously reduced, and finally they are ground into particles within 1mm, and are evenly mixed with the sewage to ensure its fluidity. While the grinding and crushing disc 7.3 is rotating, the rotating lifting impeller 7.4 below it also rotates synchronously at high speed, so that a vortex is generated at the bottom of the sewage collection chamber 2, and the mixed sewage crushed by the grinding and crushing disc 7.3 is sucked out, enters the sewage discharge chamber 3, and rises along the wall, and enters the anti-backflow storage drainage pipe 8 connected to the drainage outlet of the tank body 1.

[0022] Normally, the connecting openings of the sewage collecting chamber 2 and the sewage discharge chamber 3 are arranged at the same height as the rotating lifting impeller 7.4, the drainage port is higher than the water inlet 4, and the anti-backflow storage drainage pipe 8 connected to the drainage port is a B-shaped flushing pipe with the outlet end tilted downward, and the inlet end is also equipped with an anti-backflow valve plate 9 as a non-return mechanism. When the treated sewage enters the anti-backflow storage drainage pipe 8 from the sewage discharge chamber 3, the sewage's own gravity potential energy impacts the municipal sewage pipe, preventing the particles in the sewage from being deposited in the municipal pipe.

[0023] The facility of the present invention has low engineering cost, simple maintenance, and convenient operation and management. It can crush large particles of debris in sewage, alleviate the blockage and siltation problems that may occur in sewage pipes, improve the biodegradability of sewage treatment plants through crushing treatment, and play an important role in the resource reuse of fecal and urine sewage.

[0024] It should be noted that, in the description of the present invention, terms indicating orientation or positional relationships, such as "front", "rear", "left", "right", "vertical", "horizontal", "inside", "outside", etc., are based on the orientation or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
