Description

Technical Field

[0001] The present invention relates to the technical field of groundwater remediation, and specifically to an in-situ remediation and treatment system for groundwater in a landfill. Background Art

[0002] The leachate of a landfill mainly comes from precipitation and the internal water content of the garbage itself. It is a high-concentration organic wastewater with complex components. Inevitably, it will pollute the groundwater when infiltrating into the ground. Therefore, it is necessary to remediate the groundwater at the landfill to reduce water source pollution from the source.

[0003] After retrieval, the existing patent (publication number: CN117049687A) discloses an in-situ remediation and treatment system for groundwater in a landfill, which includes a chemical agent release mechanism. The chemical agent release mechanism includes an impeller, a piston cylinder, a piston rod, and a connecting rod. The piston rod is installed in the piston cylinder so that it can rotate around its own axis and also move along its own axis. A piston plate is provided on the piston rod; a medicine inlet and a medicine outlet are provided on the piston cylinder. When the piston rod drives the piston plate to reciprocate along its own axis, the chemical agent enters from the medicine inlet and is discharged from the medicine outlet. The rotation of the impeller driven by the water flow drives the piston rod to reciprocate along its own axis and rotate around its own axis. Furthermore, the piston plate is driven by the piston rod to suck the chemical agent into the medicine chamber and then spray it out. Moreover, the faster the water flow velocity, the faster the rotation speed of the impeller, the faster the piston drives the piston plate to move, and the more the chemical agent is sprayed out. Thus, the amount of sprayed chemical agent is adapted to the water flow velocity, avoiding insufficient addition of the chemical agent due to too fast water flow velocity.

[0004] It functions to suck and discharge medicine by the piston driving the piston plate to move. However, it has deficiencies. There is no blocking mechanism provided at its medicine inlet and medicine outlet. In this way, groundwater will also be sucked into the medicine outlet when sucking the medicine, which will lead to a decrease in the amount of sucked medicine. When pushing the medicine out, the mixture of groundwater and the liquid medicine will also be pushed into the medicine inlet, further reducing the entry of the liquid medicine into the water flow and affecting the treatment of groundwater. Moreover, it is just inserted into the ground. In places where the groundwater has a relatively large width, it can only treat a part and the treatment is incomplete. Summary of the Invention

Advantageous Effects

[0014] The present invention provides an in-situ remediation system for groundwater in a landfill. Compared with the prior art, it has the following advantageous effects: 1. For the in-situ remediation system for groundwater in this landfill, by setting the fixed frame, L-shaped plate, fixed tube, connecting tube, medicine suction tube and medicine outlet tube, according to the width and depth of the underground river, multiple fixed frames are spliced through the L-shaped plate and bolts and nuts, so that the water in the underground river all flows through the fixed frame. In this way, the medicine water enters the medicine guiding tube from the medicine inlet tube, then enters the medicine suction tube, connecting tube and fixed tube, and finally enters the medicine outlet tube and is discharged from the medicine outlet hole. This can make the groundwater fully contact with the liquid medicine, and the treatment is more comprehensive.

[0015] 2. For the in-situ remediation system for groundwater in this landfill, by setting the medicine pumping mechanism, anti-medicine outlet mechanism and anti-water inlet mechanism, the water flow drives the leaf plate and the crankshaft to rotate. The crankshaft pulls the connecting rod, and the connecting rod pulls the connecting rod and the piston to move. When the piston moves downward, a negative pressure is generated inside the medicine suction tube, sucking the anti-medicine outlet sealing plate. In this way, a negative pressure can be generated inside the medicine guiding tube and the medicine inlet tube, and the medicine inlet tube and the medicine guiding tube suck the medicine water, and then the medicine water enters the medicine suction tube. When the piston moves upward, the liquid medicine inside the medicine suction tube will be pushed upward, and the liquid medicine enters the inside of the connecting tube. In this way, automatic medicine suction can be achieved.

[0016] 3. For the in-situ remediation system for groundwater in this landfill, by setting the plug, after the horizontal devices are connected together, the plug is inserted into the jack of the crankshaft of another device. In this way, multiple crankshafts can rotate simultaneously. In some places, the water flow is gentle, and the rotation speed of the leaf plate and the crankshaft is slow, so the liquid medicine is sucked and discharged slowly. In places where the water flow is rapid, the rotation speed of the leaf plate and the crankshaft is fast. In this way, the faster-rotating crankshaft can drive the slower-rotating one to rotate, increasing the rotation speed of the slower-rotating crankshaft. Description of the Drawings

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figure 1-6, the present invention provides a technical solution: an in-situ groundwater remediation system for a landfill, comprising a fixed frame 16. Inside the fixed frame 16, a fixed pipe 17 is fixed. A plurality of medicine outlet pipes 8 are fixed on the outer side wall of the fixed pipe 17. The bottom end of the medicine outlet pipe 8 is fixedly connected to the inner bottom surface of the fixed frame 16. A plurality of medicine outlet holes 9 are formed on the outer side wall of the medicine outlet pipe 8. Two connecting pipes 14 are fixed on the outer side wall of the fixed pipe 17. The other end of the connecting pipe 14 is fixed with a medicine suction pipe 13. The other end of the medicine suction pipe 13 is fixed with a medicine guiding pipe 26. At the top of the medicine guiding pipe 26, there is a medicine inlet pipe 18. Inside the lower part of the medicine guiding pipe 26, a sealing cylinder 20 is screwed. A rotating rod 19 is fixed on the inner side wall of the sealing cylinder 20. At the four corners of the front and rear surfaces of the fixed frame 16, L-shaped plates 7 are fixedly provided. Fixing holes 1 are formed on the left side and the top of the L-shaped plate 7. Flange connection mechanisms 6 are integrally formed at the top and bottom of the medicine guiding pipe 26 and at the bottom of the medicine inlet pipe 18. The top of the medicine guiding pipe 26 and the bottom of the medicine inlet pipe 18 are fixedly connected by a plurality of bolts and nuts, so that water flow can completely pass through the device, enabling the water flow and the liquid medicine to fully contact and achieve complete treatment. A fixed rod 12 is fixed between two fixing plates 10. A reinforcing plate 11 is fixed on the outer side wall of the medicine guiding pipe 26. The rear end of the reinforcing plate 11 is fixedly connected to the front surface of the fixed rod 12, which can improve the stability of the medicine guiding pipe 26.

[0021] Furthermore, a medicine extraction mechanism 2 is provided in front of the fixed frame 16. The medicine extraction mechanism 2 includes a crankshaft 201. A plurality of blade plates 202 are fixed to the outer sidewall of the crankshaft 201. Two connecting rods 203 are rotatably connected to the outer sidewall of the crankshaft 201. The other end of the connecting rod 203 is rotatably connected to a connecting rod 204. The other end of the connecting rod 204 is fixed with a piston 205. The outer sidewall of the piston 205 is slidably connected to the inner sidewall of the medicine suction pipe 13. Two fixing plates 10 are rotatably connected to the outer sidewall of the crankshaft 201. The other end of the fixing plate 10 is fixedly connected to the front surface of the fixed frame 16. In this way, the medicine liquid can be automatically extracted. An anti-drug-out mechanism 4 is provided inside the medicine suction pipe 13. The anti-drug-out mechanism 4 includes an anti-drug-out fixed ring 401. The outer sidewall of the anti-drug-out fixed ring 401 is fixedly connected to the inner sidewall of the medicine suction pipe 13. An anti-drug-out spring 402 is fixed to the rear surface of the anti-drug-out fixed ring 401. The other end of the anti-drug-out spring 402 is fixed with an anti-drug-out plugging plate 403. An anti-drug-out plugging ring 404 is fixed inside the medicine suction pipe 13 behind the anti-drug-out plugging plate 403. In this way, when the medicine liquid is pushed, the medicine liquid is prevented from flowing back into the inside of the medicine guiding pipe 26. An anti-water-inlet mechanism 5 is provided inside the connecting pipe 14. The anti-water-inlet mechanism 5 includes an anti-water-inlet fixed ring 501. The outer sidewall of the anti-water-inlet fixed ring 501 is fixedly connected to the inner sidewall of the connecting pipe 14. An anti-water-inlet spring 502 is fixed to one end of the anti-water-inlet fixed ring 501 close to the medicine suction pipe 13. The other end of the anti-water-inlet spring 502 is fixed with an anti-water-inlet plugging plate 503. An anti-water-inlet plugging ring 504 is provided on the side of the anti-water-inlet plugging plate 503 away from the anti-water-inlet spring 502. The outer sidewall of the anti-water-inlet plugging ring 504 is fixedly connected to the inner sidewall of the connecting pipe 14. In this way, the groundwater is prevented from being sucked. A plurality of through holes 22 penetrating through the front and back and left and right are respectively formed on the front surface of the anti-drug-out fixed ring 401 and the left side of the anti-water-inlet fixed ring 501. In this way, the medicine liquid can pass through.

[0022] Furthermore, a receiving hole 24 is formed at the right end of the crankshaft 201. A compression spring 23 is fixed inside the receiving hole 24. The other end of the compression spring 23 is fixed with a plug 21. A jack 25 is formed on the left side of the crankshaft 201. In this way, a plurality of crankshafts 201 can rotate synchronously. A circular shell 3 is rotatably connected to the outer sidewall of the crankshaft 201. A limiting rod 15 is fixed to the outer sidewall of the circular shell 3. The other end of the limiting rod 15 is fixedly connected to the fixed frame 16. The blade plates 202 are located inside the circular shell 3. In this way, all the blade plates 202 and the crankshaft 201 can rotate in the same direction.

[0023] During operation, according to the width and depth of the underground river, a plurality of fixing frames 16 are spliced through the L-shaped plates 7 and bolts and nuts. At the same time, the insertion blocks 21 are inserted into the inside of the insertion holes 25. The lowest guide medicine tube 26 is sealed with the sealing cylinder 20. The top of the upper guide medicine tube 26 is connected to the medicine inlet tube 18. The other end of the medicine inlet tube 18 is inserted into the liquid medicine. In this way, the flowing water will drive the vane 202 and the crankshaft 201 to rotate. The crankshaft 201 pulls the connecting rod 203, and the connecting rod 203 pulls the connecting rod 204 and the piston 205 to move. When the piston 205 moves downward, a negative pressure is generated inside the medicine suction tube 13, sucking the anti-drug outlet blocking plate 403. In this way, a negative pressure can be generated inside the guide medicine tube 26 and the medicine inlet tube 18. The medicine inlet tube 18 and the guide medicine tube 26 suck the liquid medicine, and then the liquid medicine enters the medicine suction tube 13. At the same time, the negative pressure will suck and hold the anti-water inlet blocking plate 503 to prevent the medicine outlet tube 8 from sucking in groundwater. When the piston 205 moves upward, the liquid medicine inside the medicine suction tube 13 will be pushed upward. The strong pressure pushes the anti-drug outlet blocking plate 403 to prevent the liquid medicine from entering the guide medicine tube 26. At the same time, the strong pressure pushes the anti-water inlet blocking plate 503. In this way, the liquid medicine enters the inside of the connecting tube 14 and the fixed tube 17, and finally enters the medicine outlet tube 8 and is discharged from the medicine outlet hole 9 to treat the water flow. In this way, making all the water flow through the device can make the groundwater fully contact with the liquid medicine, and the treatment is more comprehensive. At the same time, it can automatically suck and discharge medicine. And in some places, the water flow is gentle, and the rotation speed of the vane 202 and the crankshaft 201 is slow, so the liquid medicine is sucked and discharged slowly. Where the water flow is rapid, the rotation speed of the vane 202 and the crankshaft 201 is fast. In this way, the faster-rotating crankshaft 201 can drive other crankshafts 201 to rotate through the insertion blocks 21, so as to increase the rotation speed of the slower-rotating crankshaft 201.
