DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] In embodiment 1, the present invention provides Figure 1 and Figure 3 The device for preventing debris from entering the lifting pump in the regulating tank shown in the figure includes a regulating tank 100, a pumping mechanism is provided in the regulating tank 100, and the sewage in the regulating tank 100 is pumped into the subsequent treatment structure through the pumping mechanism so as to continue the subsequent treatment steps of the sewage treatment. The pumping mechanism includes a pump body 200 and a stratified extraction component 300. The pump body 200 is fixedly arranged at a side position outside the regulating tank 100. The pump body 200 can adopt a lifting pump. The water inlet of the pump body 200 is connected to a delivery pipe 101. One end of the delivery pipe 101 extends to the inside of the regulating tank 100. The stratified extraction component 300 is connected to the water inlet of the pump body 200. The stratified extraction component 300 is provided with a water outlet connected to one end of the delivery pipe 101, and the bottom of the stratified extraction component 300 is provided with multiple water inlet ends of different heights and controllable opening and closing. By adjusting the opening of the water inlet ends at different heights on the stratified extraction component 300, and then cooperating with the pump body 200 and the delivery pipe 101, it is possible to extract sewage at different liquid level positions in the regulating tank 100, thereby ensuring the extraction of sewage in the regulating tank 100, and at the same time avoiding the bottom of the pumping pipe from penetrating too deep into the regulating tank 100, which may easily bring out the accumulated mud deposited at the bottom of the regulating tank 100, thereby helping to ensure the normal operation of subsequent treatment structures.

[0022] The layered extraction assembly 300 includes a branch pipe 301 and a plurality of first extraction pipes 302. The lengths of the plurality of first extraction pipes 302 are different. Specifically, the plurality of first extraction pipes 302 on the branch pipe 301 can be gradually increased in a direction away from the pump body 200, so that the bottom ports of the plurality of first extraction pipes 302 penetrate into the regulating tank 100 at different depths to achieve the purpose of adapting to different liquid levels. The tops of the plurality of first extraction pipes 302 are all equipped with first valves 303. The plurality of first extraction pipes 302 are respectively connected to the branch pipe 301 through the first valves 303. The first valves 303 can be used to An electromagnetic valve is used to control the opening and closing of the connection between the corresponding first extraction pipe 302 and the branch pipe 301 through the first valve 303, so that the first valve 303 on the first extraction pipe 302 at the corresponding position can be controlled to open according to the liquid level height inside the regulating tank 100, and the first valves 303 on other first extraction pipes 302 can be closed. In this way, the sewage above the liquid level in the regulating tank 100 can be pumped into the subsequent treatment structure through the first extraction pipe 302, the delivery pipe 101 and the pump body 200, so as to prevent the sludge deposited at the bottom of the regulating tank 100 from being pumped into the subsequent treatment structure and affecting normal operation.

[0023] In a preferred embodiment, the bottom ends of multiple first extraction tubes 302 are fixedly connected to a first horn sleeve 304, and the inner side away from the port of the first extraction tube 302 is fixedly connected to a mesh cover 400. The setting of the first horn sleeve 304 can increase the water inlet area, and cooperate with the mesh cover 400 to play an auxiliary filtering role, further preventing impurities from entering the first extraction tube 302.

[0024] Example 2, as Figure 2 and Figure 3 As shown, the layered extraction component 300 also includes a hollow disk 311, and a plurality of water inlets are opened on the bottom end of the hollow disk 311. The plurality of water inlets of the hollow disk 311 are fixedly connected to a second extraction pipe 312. The lengths of the plurality of second extraction pipes 312 are different. A second valve 313 is fixedly installed between the plurality of second extraction pipes 312 and the hollow disk 311. The top end of the hollow disk 311 is fixedly connected to a bent pipe 315. The end of the bent pipe 315 away from the hollow disk 311 is connected to the branch pipe 301. The bottom end of the second extraction pipe 312 is fixedly connected to the second horn sleeve 313. 4. The second horn sleeve 314 is in the shape of a horn that is narrow at the top and wide at the bottom. A mesh cover 400 can also be installed at the bottom port of the second horn sleeve 314. Compared with the branch pipe 301 in Example 1, the hollow disk 311 can reduce the occupied area and can be equipped with a larger number of second extraction pipes 312, so that more second extraction pipes 312 can be placed in local positions in the regulating tank 100, thereby adapting to the use of more liquid levels in the regulating tank 100. Similarly, the second valve 313 can also be controlled by a solenoid valve, and the bent pipe 315 can facilitate the connection between the delivery pipe 101 and the hollow disk 311.
