Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0041] See also Figure 1-8 The present invention provides a technical solution: an intelligent groundwater pollution treatment device, comprising:

[0042] A liquid inlet pipe 1 and a biological purification pool 6, a filter tank 2 is fixedly embedded on the top of the liquid inlet pipe 1, the liquid inlet pipe 1 extends into the ground, and a pump is used to pump groundwater into the filter tank 2;

[0043] The filter assembly is arranged in the filter tank 2, and the filter assembly is used to filter the water pumped into the filter tank 2 by the liquid inlet pipe 1. The filter assembly includes a filter tube 321 fixedly installed in the filter tank 2. The inner wall of the filter tube 321 is fixedly installed with a bottom plate 301, a first partition plate 302, a second partition plate 303, a top plate 304, a bearing plate 305 and a third partition plate 306 from bottom to top, and the liquid inlet pipe 1 is fixedly penetrated and extended to the top of the bottom plate 301, the first partition plate 302 The first baffle 302, the second baffle 303 and the top plate 304 are all porous structures, and the pore sizes of the middle parts of the first baffle 302, the second baffle 303 and the top plate 304 are successively reduced, so that water can pass through the first baffle 302, the second baffle 303 and the top plate 304. The middle parts of the first baffle 302, the second baffle 303, the top plate 304 and the supporting plate 305 are respectively rotatably connected with a driving rod 307 through a bearing, and a liquid outlet pipe 308 is fixedly installed on the top of the middle part of the supporting plate 305. A plurality of liquid outlet grooves 309 are provided on the surface of the tube 308. The liquid outlet tube 308 is fixedly penetrated and extended to the top of the third partition 306. Activated carbon is filled between the third partition 306 and the supporting plate 305. The driving rod 307 is respectively fixedly installed with first stirring arms 310 at the top and bottom of the first partition 302, the top and bottom of the second partition 303, and the bottom of the top plate 304. The first stirring arm 310 is arranged in an arc shape. The driving rod 307 is driven by a servo motor. The liquid level of the biological purification pool 6 is lower than the height of the supporting plate 305. An installation box 311 is fixedly installed at the bottom of the first partition 302, and a nano-microbubble generating device 312 is fixedly embedded at the top of the installation box 311. The installation box 311 is rotatably connected to the surface of the driving rod 307 through a bearing, so that the nano-bubbles generated by the nano-microbubble generating device 312 are in contact with organic pollutants in the water, so that the organic pollutants in the water are pre-decomposed, and the suspended matter in the water is floated at the same time.

[0044] When the above structure is in use, when groundwater is pumped into the interior of the filter tube 321, the groundwater will pass through the first partition plate 302, the second partition plate 303 and the top plate 304 in sequence. When groundwater with sediment enters the interior of the filter tube 321, the sediment will settle on the top of the bottom plate 301 due to its heavy weight. Water containing some impurities will pass through the first partition plate 302, the second partition plate 303 and the top plate 304 in sequence. A device for placing flocculants is installed at the bottom of the installation box 311, so that the water between the first partition plate 302 and the second partition plate 303 can be mixed with the flocculant. At the same time, under the action of the nano-microbubble generating device 312 generating nano-microbubbles, the suspended matter floats upward. At the same time, the nano-bubbles generated by the nano-microbubble generating device 312 come into contact with the organic pollutants in the water, so that the organic pollutants in the water are pre-decomposed.

[0045] A plurality of slag outlets 313 are provided on the side wall of the filter tube 321 corresponding to the top position of the bottom plate 301, and a plurality of slag outlets 314 are provided on the filter tube 321 corresponding to the top and bottom of the first partition plate 302, the top and bottom of the second partition plate 303, the top and bottom of the top plate 304, and the bottom position of the supporting plate 305, and the apertures of the plurality of slag outlets 314 decrease from bottom to top, and a spiral groove is provided on the top of the bottom plate 301, the first partition plate 302, the second partition plate 303, and the top plate 304, respectively, so that when the arc-shaped first stirring arm 310 is driven to rotate by the driving rod 307, the first stirring arm 310 first rotates on the spiral groove and pushes the fixed residue to the inner side wall position of the filter tube 321, and at the same time, the arc-shaped first stirring arm 310 squeezes the fixed residue to the inner wall of the filter tube 321, so that the solid residue and the suspended matter pass through the slag outlet 313 and the slag outlet 314;

[0046] When the above structure is in use, when the driving rod 307 rotates, the driving rod 307 will drive the first stirring arm 310 to rotate, and the first stirring arm 310 will first sweep the sediment on the top of the bottom plate 301, the first partition plate 302 and the second partition plate 303 through the guidance of the spiral structure on the top of the bottom plate 301 to the position of the slag outlet 313 and the slag outlet hole 314, and make the sediment pass through the slag outlet 313 and the slag outlet hole 314 into the position between the filter tank 2 and the filter tube 321. At the same time, the rotation of the first stirring arm 310 will sweep the suspended matter at the bottom of the first partition plate 302, the second partition plate 303 and the top plate 304 toward the inner wall of the filter tube 321, and as the first stirring arm 310 continues to rotate, the suspended matter is squeezed through the slag outlet hole 314 into the position between the filter tank 2 and the filter tube 321.

[0047] A second stirring arm 315 is fixedly installed on the surface of the driving rod 307 at a position between the top plate 304 and the supporting plate 305, a support arm 316 is fixedly installed on the surface of the middle bottom of the supporting plate 305, and a slag blocking ring 317 is fixedly installed on the top of the support arm 316. The slag blocking ring 317 is composed of a plurality of conical rings whose diameters increase successively from the inside to the outside, and a plurality of conical rings constituting the slag blocking ring 317 are provided with a plurality of bosses on the surfaces to prevent suspended matter from flowing upward with the water. The second stirring arm 315 is a frame-shaped structure with an open end, and the top of the second stirring arm 315 is rotatably connected to the bottom of the supporting plate 305, the slag blocking ring 317 is located on the inner wall of the second stirring arm 315, and the second stirring arm A cleaning bar 318 is fixedly installed on the inner wall of 315, and the cleaning bar 318 is located between the multiple conical rings constituting the slag blocking ring 317, so that when the cleaning bar 318 moves relative to the slag blocking ring 317, the suspended matter precipitated in the slag blocking ring 317 can be scraped out. A plurality of air guide covers 319 are fixedly installed on the top of the supporting plate 305, and a plurality of air outlet holes 320 are opened in the middle of the supporting plate 305 corresponding to the air guide covers 319 and the surface of the supporting plate 305, so that the water filtered by the slag blocking ring 317 passes through the filter tube 321 and flows to the outer layer of the supporting plate 305 and the third partition plate 306 filled with activated carbon through the guidance of the air guide covers 319, thereby increasing the time for water to pass through the activated carbon;

[0048] When the above structure is in use, the filtered water passes through the top plate 304 and flows upward. By setting the slag ring 317, the water that wants to pass through the bearing plate 305 must first pass through the slag ring 317. Since the slag ring 317 is composed of a plurality of conical rings with increasing diameters from the inside to the outside, and the surfaces of the plurality of conical rings constituting the slag ring 317 are provided with a plurality of bosses, this will slow down the water flow speed and increase the contact area with the water flow, thereby intercepting some suspended matter. At the same time, when the driving rod 307 drives the second stirring arm 315 to rotate, the second stirring arm 315 will drive the cleaning bar 318 to sweep between the plurality of conical rings of the slag ring 317, thereby preventing the suspended matter from accumulating in the slag ring 317 and affecting the water flow speed. At the same time, the swept suspended matter will accumulate and be swept by the second stirring arm 315 driven by the driving rod 307, so that it passes through the slag discharge hole 314 and enters the position between the filter tank 2 and the filter tube 321.

[0049] The filtered water will pass through the supporting plate 305 through the air outlet hole 320. Since the air outlet hole 320 is arranged at the middle of the air guide cover 319 corresponding to the supporting plate 305 and the surface of the supporting plate 305, the water entering between the supporting plate 305 and the third partition plate 306 will flow from the surface of the supporting plate 305 to the liquid outlet pipe 308 in the middle of the supporting plate 305. Since the supporting plate 305 and the third partition plate 306 are filled with activated carbon, the water will pass through the activated carbon from the edge of the activated carbon and flow to the liquid outlet pipe 308 in the middle of the activated carbon, thereby improving the effect of the activated carbon on water filtration.

[0050] A solid-liquid separation component is arranged in the filter tank 2, and the solid-liquid separation component is used to separate solids from liquids in water. The solid-liquid separation component includes a slag hopper 401 fixedly installed on the top of the filter tube 321. The inner wall of the filter tank 2, the surface of the filter tube 321 and the surface of the slag hopper 401 are rotatably connected with a shaftless spiral blade 402. A plurality of slag discharge ports 403 are opened on the side wall at the top of the slag hopper 401, and the slag discharge ports 403 are arranged in a conical shape. A driving ring 404 is fixedly installed on the top of the shaftless spiral blade 402, and the driving ring 404 is rotatably connected to the slag hopper 40 1, a gear ring is provided on the surface of the driving ring 404, and the gear ring is driven by a driving motor, so that when the driving motor cooperates with the gear ring to drive the driving ring 404 to rotate, the driving ring 404 drives the shaftless spiral blade 402 to rotate, and the solid residue and suspended matter discharged from the filter tube 321 through the slag outlet 313 and the slag outlet hole 314 are transported upward, and finally the solid residue and suspended matter are squeezed through the slag outlet 403 and enter the interior of the slag outlet 401, and a top cover 405 is fixedly installed on the top of the filter tank 2, and the driving ring 404 is rotatably connected to the inner wall of the top cover 405;

[0051] When the above structure is in use, when the driving ring 404 rotates, the driving ring 404 will drive the shaftless spiral blade 402 to rotate, and the shaftless spiral blade 402 will drive the solid residue and suspended matter in the form of sediment to be transported upward. Since the liquid level of the biological purification tank 6 is lower than the height of the supporting plate 305, the liquid level between the filter tank 2 and the filter tube 321 will not be much higher than the liquid level of the supporting plate 305.

The arc of the inner wall and the surface of the spherical shell 705 are adapted to each other so that the driving arm 704 can rotate around the center of the second fixed hemispherical shell 705 and the first fixed hemispherical shell 701. The surface of the driving rod 307 corresponding to the rotating hemispherical shell 702 is fixedly installed with a second spherical gear 710. The surface of the rotating hemispherical shell 702 corresponding to the second spherical gear 710 is fixedly installed with two first gear rings 709, and the two first gear rings 709 are respectively located in front and behind the second spherical gear 710.

[0055] When the above structure is in use, when the driving ring 404 rotates, the driving ring 404 will drive the rotating tube 501 to rotate through the connecting arm 504. At the same time, when the driving rod 307 rotates, the driving rod 307 will respectively drive the second spherical gear 710 and the third spherical gear 712 to rotate, and when the second spherical gear 710 rotates, the second spherical gear 710 will not simultaneously drive the two first gear rings 709 to rotate in the opposite direction, that is, the two first gear rings 709 will drive the rotating hemispherical shell 702 to swing back and forth, and the rotating hemispherical shell 702 will drive the driving arm 704 to swing back and forth with the center of the rotating hemispherical shell 702 as the rotation center and extending to the inner wall of the second movable groove 706. By setting the first limit block 707 and the first spherical gear 708, the swing of the driving arm 704 is smoother, and when the third spherical gear 712 rotates, the third spherical gear 712 will be driven to rotate in the opposite direction. The wheel 712 drives the two second gear rings 711 to rotate in the opposite direction, and the two second gear rings 711 drive the first spherical gear 708 to rotate, so that the first spherical gear 708 drives the driving arm 704 to rotate, and when the driving arm 704 rotates, the driving arm 704 drives the scraping arm 713 to move on the inner wall of the slag bucket 401, and at the same time cooperates with the rotation of the rotating tube 501, so that the scraping arm 713 rotates and revolves regularly on the inner wall of the slag bucket 401, and at the same time, when the driving arm 704 rotates to the highest point and the scraping arm 713 rotates to a horizontal state and is at the same height as the top of the slag bucket 401, a slag plate 714 is set, so that when the scraping arm 713 scrapes the solid residue and suspended matter inside the slag bucket 401 out of the slag bucket 401, it just falls into the slag plate 714 to complete the collection, thereby achieving the purpose of automatic solid-liquid separation and collection of solid waste.

[0056] Working principle: When in use, the groundwater is first pumped into the interior of the filter tube 321 through the liquid inlet pipe 1 by a pump, and at this time, the driving motor and the servo motor simultaneously drive the driving ring 404 and the driving rod 307 to rotate respectively;

[0057] When groundwater is pumped into the filter tube 321, it will pass through the first partition 302, the second partition 303 and the top plate 304 in sequence. When groundwater with sediment enters the filter tube 321, the sediment will settle on the top of the bottom plate 301 due to its heavy weight. Water containing some impurities will pass through the first partition 302, the second partition 303 and the top plate 304 in sequence. A device for placing flocculants is installed at the bottom of the installation box 311, so that the water between the first partition 302 and the second partition 303 can be mixed with the flocculants. At the same time, under the action of the nano-microbubble generating device 312 generating nano-microbubbles, the suspended matter floats upward. At the same time, the nano-bubbles generated by the nano-microbubble generating device 312 come into contact with the organic pollutants in the water, so that the organic pollutants in the water are pre-decomposed.

[0058] When the driving rod 307 rotates, the driving rod 307 drives the first stirring arm 310 to rotate, and the first stirring arm 310 first sweeps the sediment on the top of the bottom plate 301, the first partition plate 302 and the second partition plate 303 toward the position of the slag outlet 313 and the slag outlet hole 314 through the guide of the spiral structure on the top of the bottom plate 301, and makes the sediment pass through the slag outlet 313 and the slag outlet hole 314 into the position between the filter tank 2 and the filter tube 321, and at the same time, the rotation of the first stirring arm 310 sweeps the suspended matter on the bottom of the first partition plate 302, the second partition plate 303 and the top plate 304 toward the inner wall of the filter tube 321, and as the first stirring arm 310 continues to rotate, the suspended matter is squeezed through the slag outlet hole 314 into the position between the filter tank 2 and the filter tube 321;

[0059] The filtered water passes through the top plate 304 and flows upward. By setting the slag ring 317, the water must first pass through the slag ring 317 if it wants to pass through the bearing plate 305. Since the slag ring 317 is composed of a plurality of conical rings with increasing diameters from the inside to the outside, and a plurality of bosses are provided on the surfaces of the plurality of conical rings constituting the slag ring 317, this will slow down the water flow speed and increase the contact area with the water flow, thereby intercepting some suspended matter. At the same time, when the driving rod 307 drives the second stirring arm 315 to rotate, the second stirring arm 315 will drive the cleaning bar 318 to sweep between the plurality of conical rings of the slag ring 317, thereby preventing the suspended matter from accumulating in the slag ring 317 and affecting the water flow speed. At the same time, the swept suspended matter will accumulate and be swept by the second stirring arm 315 driven by the driving rod 307, so that it passes through the slag discharge hole 314 and enters the position between the filter tank 2 and the filter tube 321;

[0060] The filtered water will pass through the carrier plate 305 through the air outlet hole 320. Since the air outlet hole 320 is arranged at the middle of the air guide cover 319 corresponding to the carrier plate 305 and the surface position of the carrier plate 305, the water entering between the carrier plate 305 and the third partition plate 306 will flow from the surface position of the carrier plate 305 to the liquid outlet pipe 308 in the middle position of the carrier plate 305. Since the inside of the carrier plate 305 and the third partition plate 306 are filled with activated carbon, the water will pass through the activated carbon from the edge position of the activated carbon and flow to the liquid outlet pipe 308 in the middle of the activated carbon, thereby improving the effect of the activated carbon on water filtration;

[0061] When the water filtered by the activated carbon enters the liquid outlet pipe 308 through the liquid outlet tank 309, it enters the rotating tube 501 in the liquid outlet pipe 308, and enters the biological purification pool 6 through the connecting cover 502 and the connecting pipe 503, and microorganisms are added to the biological purification pool 6. The water is purified again by the microorganisms, so as to achieve the purpose of thoroughly and efficiently purifying the groundwater, and avoid the influence of impurities on the purification of groundwater by microorganisms. The purified water is finally discharged to the earth;

[0062] When the driving ring 404 rotates, the driving ring 404 drives the shaftless spiral blade 402 to rotate, and the shaftless spiral blade 402 drives the solid residue and suspended matter in the form of sediment to be transported upward. Since the liquid level of the biological purification pool 6 is lower than the height of the supporting plate 305, the liquid level between the filter tank 2 and the filter tube 321 will not be much higher than the liquid level of the supporting plate 305. Under the continuous transporting action of the shaftless spiral blade 402, the solid residue and suspended matter will accumulate on the top of the filter tank 2, and will be continuously compressed as the shaftless spiral blade 402 rotates, so that the solid residue and suspended matter will pass through the slag discharge port 403 and enter the interior of the slag discharge hopper 401, thereby realizing the separation of the fixed liquid.

[0063] When the driving ring 404 rotates, the driving ring 404 will drive the rotating tube 501 to rotate through the connecting arm 504. At the same time, when the driving rod 307 rotates, the driving rod 307 will respectively drive the second spherical gear 710 and the third spherical gear 712 to rotate. When the second spherical gear 710 rotates, the second spherical gear 710 will not simultaneously drive the two first gear rings 709 to rotate in the opposite direction, that is, the two first gear rings 709 will drive the rotating hemispherical shell 702 to swing back and forth, and the rotating hemispherical shell 702 will drive the driving arm 704 to swing back and forth with the center of the rotating hemispherical shell 702 as the rotation center and extending to the inner wall of the second movable groove 706. By setting the first limit block 707 and the first spherical gear 708, the swing of the driving arm 704 is smoother, and when the third spherical gear 712 rotates, the third spherical gear 712 will The two second gear rings 711 are driven to rotate in the opposite direction, and the two second gear rings 711 drive the first spherical gear 708 to rotate, so that the first spherical gear 708 drives the driving arm 704 to rotate, and when the driving arm 704 rotates, the driving arm 704 drives the scraping arm 713 to move on the inner wall of the slag bucket 401, and at the same time, cooperate with the rotation of the rotating tube 501, so that the scraping arm 713 can rotate and revolve regularly on the inner wall of the slag bucket 401, and at the same time, when the driving arm 704 rotates to the highest point and the scraping arm 713 rotates to a horizontal state and is at the same height as the top of the slag bucket 401, a slag plate 714 is set, so that when the scraping arm 713 scrapes the solid residue and suspended matter inside the slag bucket 401 out of the slag bucket 401, it just falls into the slag plate 714 to complete the collection, thereby achieving the purpose of automatic solid-liquid separation and collection of solid waste.
