[0056] The groundwater remediation device described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the groundwater remediation device described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described in some examples may also be combined in other examples.

[0057] Embodiment 1

[0058] like Figure 1 and Figure 5 As shown, a groundwater remediation device according to an embodiment of the present invention comprises a treatment cylinder 1 with an opening formed upward, a filtering mechanism 2, a cleaning mechanism 3 and an adsorption mechanism 4;

[0059] A drain valve 7 is provided at the bottom of the treatment cylinder 1;

[0060] The filtering mechanism 2 and the cleaning mechanism 3 are arranged on the treatment cylinder 1, and the treatment cylinder 1 is connected with an adsorption mechanism 4 for adsorbing the treated water;

[0061] The filter mechanism 2 is connected to a driving member, which drives the filter mechanism 2 to rotate and filter. When the filter mechanism 2 is rotated out of the treatment cylinder 1, the filter mechanism 2 self-cleans its filter area. With the continuous driving of the driving member, the filter mechanism 2 rotates to cooperate with the cleaning mechanism 3 for vibration and scraping.

[0062] Reference Figure 2-Figure 7 and Fig. 9 As shown, in order to perform filtering and self-cleaning, the filtering mechanism 2 includes a conical fixed tube 21, a conical rotating tube 22, a filter screen 23 and a self-cleaning part. The number of the filter screens 23 is multiple, and the multiple filter screens 23 are arranged at equal intervals. The filter screen 23 is non-hollowed near the conical rotating tube 22. The conical rotating tube 22 is rotatably sleeved on the central axis of the treatment tube 1 and cooperates with the driving part. The conical fixed tube 21 is located inside the conical rotating tube 22 and is fixedly connected to the treatment tube 1 through a connecting plate 24. The filter screen 23 is fixedly installed on the outer periphery of the conical rotating tube 22. A leakage port 221 is opened on the conical rotating tube 22, and a port with a diameter larger than the leakage port 221 is opened on the top of the conical fixed tube 21. The discharge port 211 of the material port 221 is to facilitate the salvaged objects to enter the interior of the discharge port 211. The self-cleaning part is arranged on the filter screen 23. The self-cleaning part includes a scraper frame 25 which is slidably sleeved on the filter screen 23. A magnetic strip 26 for adsorbing the scraper frame 25 is embedded at one end of the filter screen 23 away from the conical rotating tube 22. The magnetic strip 26 serves to limit the position of the scraper frame 25. As the filter screen 23 is rotated out of the processing tube 1 and gradually presents a vertical state, the adsorption force of the magnetic strip 26 is less than the gravity of the scraper frame 25, and the scraper frame 25 moves along the filter screen 23 toward the conical rotating tube 22 to scrape the filter screen 23. The objects dropped on the filter screen 23 are referred to Figure 7The direction marked by the arrow passes through the leakage port 221 and the discharge port 211 to enter the interior of the conical fixed tube 21. The driving part includes a driving motor 5 and a reducer 6. The driving motor 5 and the reducer 6 are both installed on the processing tube 1. The driving motor 5 is connected to the conical rotating tube 22 through the reducer 6. The driving motor 5 drives the conical rotating tube 22 through the reducer 6 to drive the filter screen 23 to rotate. One end of the conical rotating tube 22 is a closed end, and a driving rod 27 is fixedly connected to the inside of the conical rotating tube 22. A spiral blade 28 is fixedly mounted on the driving rod 27. The spiral blade 28 is adapted to the inner wall of the conical fixed tube 21, and is arranged with a spiral diameter increasing from one end to the other end. The driving rod 27 passes through the closed end of the conical rotating tube 22 (the driving rod 27 is fixedly sleeved with the conical rotating tube 22) and is axially connected to the output shaft of the reducer 6.

[0063] In order to increase the stability of the driving rod 27 during rotation, a right-angle plate 29 is installed on the processing cylinder 1. The right-angle plate 29 is rotatably connected to the driving rod 27 to stabilize the radial position of the driving rod 27 during rotation.

[0064] In order to clean and impact the filter screen 23, the cleaning mechanism 3 includes a scraper 31, a guide frame 32, a return spring 33 and a guide rod 34. The guide frame 32 is obliquely installed on the processing cylinder 1, and guide grooves are provided on both sides of the guide frame 32. Protrusions are formed on both sides of the scraper 31 and extend into the interior of the guide groove and are slidably connected with the guide rod 34. One end of the guide rod 34 is fixedly connected to the inner wall of the guide groove. The return spring 33 is movably sleeved on the outer periphery of the guide rod 34. One end of the return spring 33 is fixedly connected to the protrusion (the protrusion is block-shaped and is slidably connected to the inner wall of the guide groove), and the other end is fixedly connected to the inner wall of the guide groove.

[0065] As the filter screen 23 continuously rotates and approaches the scraper 31, the scraper 31 is continuously pushed, so that the protrusion moves along the guide groove, compressing the return spring 33 to store energy, so that after the filter screen 23 passes through the scraper 31, the scraper 31 is moved back by the return spring 33 to impact the next filter screen 23, thereby playing a vibrating role.

[0066] Reference Figure 2 , Figure 8 , Fig.10 and Fig.11 In order to scrape the objects on the scraper 31, a mounting shell 35 is fixedly installed on the guide frame 32, and a cleaning plate 37 is rotatably connected to the mounting shell 35 through a rotating shaft 36. An inclined portion 38 is provided at the bottom of the cleaning plate 37, and the cleaning plate 37 is connected to the mounting shell 35 through a torsion spring 39.

[0067] As the scraper 31 continues to move toward the guide frame 32, the scraper 31 acts on the inclined portion 38, and the cleaning plate 37 rotates around the rotating shaft 36 (during this rotation, the torsion spring 39 is energized), so that the cleaning plate 37 rotates to scrape the top surface of the scraper 31. When the scraper 31 moves back and releases the abutment against the inclined portion 38, the energized torsion spring 39 is restored, so that the cleaning plate 37 rotates back to a vertical state, causing the objects on the cleaning plate 37 to scatter, and a collection box is placed in the scattering area of ​​the cleaning plate 37.

[0068] Reference Figure 5 The adsorption mechanism 4 includes a treatment tank 41, which is connected to the treatment cylinder 1. An activated carbon layer 42 is laid inside the treatment tank 41, and a drainage port is provided at the bottom of the treatment tank 41. Due to its porous structure and rich functional groups, activated carbon exhibits strong adsorption, catalytic oxidation and biodegradation capabilities in sewage treatment, and can effectively remove impurities such as suspended matter, organic matter, color and odor in water.

[0069] As a further optimization scheme of the present invention, the drain valve 7 is connected to the treatment cylinder 1 through the drain pipe 8. One side of the drain pipe 8 is connected to the connecting pipe 9, and the connecting pipe 9 is provided with a one-way valve. When air is introduced into the interior of the treatment cylinder 1 (the connecting pipe 9 can be supplied with air by an air pump), the drain valve 7 is in a closed state. When the liquid in the treatment cylinder 1 is discharged, due to the setting of the one-way valve, the discharged liquid cannot enter the interior of the connecting pipe 9, and enters the interior of the treatment tank 41, and is filtered through the activated carbon layer 42 and discharged.

[0070] Embodiment 2

[0071] On the basis of the above-mentioned embodiment 1, the present invention proposes a groundwater remediation method, which uses the above-mentioned groundwater remediation device and includes the following steps:

[0072] S1. Sedimentation treatment:

[0073] The underground sewage and flocculant are added into the treatment cylinder 1, and air is supplied through the connecting pipe 9 to perform flocculation treatment;

[0074] S2. Filter the precipitate:

[0075] The cleaning mechanism 3 is driven by the driving member to filter out the sediment inside the treatment cylinder 1;

[0076] S3. Clean the filtered sediment:

[0077] The filter mechanism 2 performs self-cleaning by rotating, and is cleaned by the cleaning mechanism 3 as it rotates, and the sediment is cleaned onto the cleaning mechanism 3;

[0078] S4, filtering again:

[0079] The wastewater in the treatment tube 1 enters the adsorption mechanism 4 and is discharged after being filtered.

[0080] Example 3

[0081] The difference from Example 2 is that:

[0082] Reference Figure 1 , Figure 5 , Figure 12-14 The scraper 31 is provided with a blowing cleaning mechanism 10, which includes a sleeve 101 installed on both sides of the scraper 31, and the interior of the sleeve 101 is connected to a slide plate 103 through a return spring 102. The two slide plates 103 are provided with a rotating joint 104, and one end of the two rotating joints 104 is connected to a nozzle 105. The other end of one rotating joint 104 is connected to a diversion channel 1001 opened in the wall of the treatment tube 1 through a vent pipe 106. The bottom wall is provided with an air hole 1002 connected to the diversion channel 1001, the other end of the other rotary joint 104 is connected to the air supply pipe 107, the nozzle 105 is provided with a spray hole 1051, and the interior of the nozzle 105 is installed with an auger blade 108, when the cleaning plate 37 cleans the scraper 31, when it is located between the scraper 31 and the nozzle 105, it can act on the nozzle 105 to move upward, so that when the cleaning plate 37 stops cleaning the scraper 31, the nozzle 105 moves back.

[0083] Hot air is introduced from the air supply pipe 107 and enters the interior of the nozzle 105. Due to the setting of the auger blade 108, a spiral channel is formed between the auger blade 108 and the nozzle 105. The hot air drives the nozzle 105 to rotate through the spiral channel, and blows air to the filter surface of the filter 23 (accompanied by the contact between the filter 23 and the scraper 31, the nozzle 105 rotates continuously and blows hot air to the filter 23) to clean its mesh and mesh surface, and increase the cleanliness when it is used again. At the same time, the hot air enters the interior of the diversion channel 1001 through the ventilation pipe 106, and is ejected through the air hole 1002 to act on the sewage in the treatment cylinder 1, and brings the following effects:

[0084] 1. Accelerate the flocculation and sedimentation speed: hot air can increase the temperature of sewage, speed up the molecular movement, and make the flocculant combine with the pollutants in the sewage more quickly to form larger flocs, thereby accelerating the sedimentation process and improving the sedimentation efficiency. To a certain extent, it can alleviate the filter blockage problem caused by excessive sediment (too many fine sediments), reduce equipment downtime, and ensure the continuity of treatment.

[0085] 2. Promote neutralization reaction: The increase in temperature helps the neutralization liquid to react more fully with the acidic or alkaline substances in the sewage, making the reaction more thorough, improving the pH adjustment effect of the sewage, facilitating the subsequent treatment process, and improving the efficiency and quality of sewage treatment as a whole.

[0086] 3. Reduce the content of pollutants: The introduction of hot air can promote the dissolution and decomposition of some insoluble pollutants, converting pollutants that were originally difficult to remove into a form that is easier to handle, thereby further reducing the content of pollutants in sewage and improving the water quality of the effluent.

[0087] Working principle:

[0088] Underground sewage is added into the interior of the treatment tube 1, and flocculants and neutralizers are added into the interior of the treatment tube 1, and air is introduced into the bottom of the treatment tube 1 through the connecting pipe 9 to mix the liquid inside the treatment tube 1 and increase the flocculation effect. The driving motor 5 drives the conical rotating tube 22 and the spiral blades 28 to rotate through the reducer 6, and the filter screen 23 rotates along with the rotation of the conical rotating tube 22 to salvage the sediment and floating objects inside the treatment tube 1. As the filter screen 23 is continuously rotated out of the treatment tube 1 and presents a vertical state, the objects on the salvage surface of the filter screen 23 fall under the action of gravity, pass through the leakage port 221 and the discharge port 211 into the interior of the conical fixed pipe 21, and are discharged by the rotation of the spiral blades 28. As the filter screen 23 continues to rotate, the scraper frame 25 moves toward the conical rotating tube 22 under the action of gravity to clean the filter screen 23. The cleaned objects enter the interior of the leakage port 221. As the filter screen 23 rotates, the filtering surface of the filter screen 23 (refer to Figure 5) contacts with the scraper 31, and the scraper 31 plays the role of scraping the filter screen 23. Under the action of the return spring 33, the scraper 31 adapts to the rotation of the filter screen 23 to perform self-adaptive scraping. After a filter screen 23 passes through the scraper 31, the return spring 33 is in the limit position after energy storage. The return spring 33 drives the scraper 31 to move back to play the role of impact vibration on the next filter screen 23, so that the filter screen 23 vibrates after being impacted to increase the cleaning effect of the filter screen 23. The air supply pipe 107 is responsible for introducing hot air, and the hot air enters the interior of the nozzle 105. Due to the setting of the auger blade 108, a spiral channel is formed between it and the nozzle 105. When the hot air passes through the spiral channel, two effects will be produced. One is to drive the nozzle 105 rotates, and secondly, air is blown to the filtering surface of the filter 23 during the rotation process. While the filter 23 is in contact with the scraper 31, the nozzle 105 continues to rotate and blows hot air to the filter 23. This operation can effectively clean the mesh and mesh surface of the filter 23, thereby increasing its cleanliness when it is used again. In addition, the hot air will also pass through the vent pipe 106 into the diversion channel 1001, and then be ejected through the air hole 1002 to act on the sewage in the treatment cylinder 1. This process can enhance the flocculation effect of the sewage, so that the pollutants in the sewage can be more efficiently aggregated and precipitated, thereby improving the quality and efficiency of sewage treatment. After the filter 23 passes through the scraper 31 and is in an inclined state, the scraper frame 25 gradually moves to the filter 23 away from the conical rotating tube 22.

[0089] The above describes an embodiment of the present invention, but this embodiment is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Under the guidance of this embodiment, ordinary technicians in this field can also make many forms, all of which are protected by this embodiment.
