Description

Technical Field

[0001] This invention relates to the field of soil remediation technology, and in particular to a system for inducing the migration and discharge of water-soluble pollutants in soil. Background Technology

[0002] Contaminated soil remediation is a crucial measure for protecting natural resources. To this end, engineers and researchers have conducted extensive research on contaminated soil treatment. Currently, common treatment methods for contaminated soil mainly include in-situ solidification and pollutant extraction. In-situ solidification involves adding cement or other solidifying agents to the soil, forming a unified whole with the pollutants, soil, and cementitious materials, thus preventing the spread of pollutants. Pollutant extraction uses physicochemical processes to extract pollutants from the soil, preserving its usability. Comparing the two methods, solidified soil lacks agricultural value because it contains pollutants and lacks the conditions for vegetation growth. Extraction, on the other hand, extracts pollutants or reduces their concentration, allowing for the planting of non-utilitarian vegetation on the soil surface, which is of significant value for the full utilization of soil resources. Therefore, when possible, engineers tend to use extraction to reduce the pollutant content in the soil. Currently, soil pollution mainly originates from sewage discharge. Sewage continuously infiltrates the soil, causing widespread contamination. Therefore, soil purification requires removing the contaminated soil, which not only increases the workload but also fails to effectively solve the problem of sewage-contaminated soil.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example 1

[0032] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a soil water-soluble pollutant induced migration and discharge system. The soil water-soluble pollutant induced migration and discharge system includes a filter component 100 and a mixing component 200. Through the arrangement of the two, sewage can be effectively purified and discharged, so that the soil is not polluted by sewage and the soil has full utilization value.

[0033] The filter assembly 100 includes a housing 101, a filter element 102, a dosing device 103, a mixing tank 104, and a drain element 105. The filter element 102 is disposed on the outside of the housing 101, the dosing device 103 is disposed inside the housing 101, the mixing tank 104 is fixed on the dosing device 103, and the drain element 105 is disposed on one side of the mixing tank 104.

[0034] By burying the tank 101 at the sewage discharge point, the sewage is filtered through the filter element 102 and then enters the mixing tank 104. The chemical agent inside the dosing element 103 is then delivered to the mixing tank 104 to neutralize the sewage and reduce the harmful substances in the sewage, thereby purifying the sewage. The purified sewage is then discharged into the soil through the drainage element 105, thus solving the problem of sewage polluting the soil.

[0035] The mixing component 200 is disposed on the mixing box 104 and includes a fixed box 201, a driving component 202, a mixing component 203, a limiting component 204, and an adjusting component 205. The fixed box 201 is disposed at the bottom of the box body 101, the driving component 202 is located inside the fixed box 201, the mixing component 203 is disposed inside the mixing box 104, the limiting component 204 is fixed inside the box body 101, and the adjusting component 205 is disposed on the driving component 202.

[0036] The fixed box 201 is rectangular and is used to install the drive component 202. The drive component 202 drives the mixing component 203 to rotate, thereby agitating the sewage and chemicals inside the mixing box 104. This allows the chemicals and sewage inside the mixing box 104 to react quickly, thus accelerating the purification of harmful substances in the sewage. The limiting component 204 is used to open or close the discharge of the dosing component 103, which helps to control the addition of chemicals. The adjusting component 205 is used to cooperate with the drive component 202 to drive the mixing box 104 to move up and down, which helps to agitate and mix the sewage. Example 2

[0037] Reference Figures 2-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, the filter element 102 includes a fixed pipe 102a, a water inlet tank 102b, and a filter screen 102c. The fixed pipe 102a is located on the outside of the housing 101, the water inlet tank 102b is fixed to the side of the fixed pipe 102a, and the filter screen 102c is located on the top of the fixed pipe 102a.

[0039] The fixed pipe 102a is used to transport the wastewater filtered by the filter screen 102c to the inlet tank 102b. Both sides of the inlet tank 102b are provided with through grooves that are connected to the fixed pipe 102a. There are three fixed pipes 102a, all of which are fixed to the outside of the box body 101. The fixed pipes 102a on both sides of the box body 101 are fixed at an angle to facilitate the flow of wastewater into the inlet tank 102b. There are four filter screens 102c, and the four filter screens 102c are respectively fixed to the fixed pipe 102a and the top of the inlet tank 102b.

[0040] The dosing device 103 includes a reagent tank 103a, a connecting pipe 103b, and a liquid outlet pipe 103c. The reagent tank 103a is fixed inside the housing 101, the connecting pipe 103b is connected to the bottom of the housing 101, and the liquid outlet pipe 103c is connected to one side of the connecting pipe 103b.

[0041] The reagent tank 103a is rectangular and is used to store externally added chemical reagents. When the chemical reagents are transported, the chemical reagents inside the reagent tank 103a are transported to the outlet pipe 103c through the connecting pipe 103b, and then from the outlet pipe 103c to the mixing tank 104, so that the chemical reagents and sewage are together in the mixing tank 104.

[0042] The dosing unit 103 also includes a fixed plate 103j, a slider 103d, a connecting plate 103e, a movable block 103f, a support block 103g, a first spring 103h, and a positioning post 103i. The fixed plate 103j is fixed inside the housing 101. A groove S is provided on one side of the fixed plate 103j. The slider 103d slides in the groove S. The connecting plate 103e is fixed to one side of the slider 103d. The movable block 103f slides in the groove S. The support block 103g is fixed inside the housing 101. The first spring 103h is fixed to the top of the support block 103g. The top of the first spring 103h is fixed to the movable block 103f. The mixing tank 104 is fixed to the top of the connecting plate 103e. The positioning post 103i is fixed to the top of the movable block 103f.

[0043] By setting the fixed plate 103j and the slide groove S, the slider 103d can be limited when sliding in the slide groove S. The mixing box 104 is limited by the connecting plate 103e, so that the mixing box 104 can move vertically up and down. The top of the positioning column 103i is located in the connecting pipe 103b. The moving block 103f drives the positioning column 103i to move downward, so that the top of the positioning column 103i moves downward, and the chemical agent inside the reagent tank 103a flows into the outlet pipe 103c through the connecting pipe 103b. Then, the outlet pipe 103c transports the chemical agent into the mixing box 104. After that, the driving component 202 drives the mixing component 203 to stir the sewage and chemical agent inside the mixing box 104, so that the sewage and chemical agent are fully mixed.

[0044] The drainage component 105 includes a drain pipe 105a, a support column 105b, a lever 105c, a baffle 105d, a water receiving plate 105e, a conveying pipe 105f, a fixing block 105g, and a torsion spring 105h. The drain pipe 105a is connected to one side of the mixing tank 104. The support column 105b is rotatably connected inside the drain pipe 105a. The lever 105c is fixed to one end of the support column 105b. The baffle 105d is fixed to the outside of the support column 105b. The water receiving plate 105e is fixed to the bottom wall inside the tank 101. One end of the conveying pipe 105f is connected to the water receiving plate 105e. The fixing block 105g is fixed to the inner wall of the tank 101. The torsion spring 105h is sleeved on the outside of the support column 105b.

[0045] The drain pipe 105a is used to discharge the purified wastewater inside the mixing tank 104. When the mixing tank 104 moves downward, it moves the drain pipe 105a, which in turn moves the support column 105b, the lever 105c, and the baffle 105d. The bottom of the lever 105c contacts the fixing block 105g, which in turn pushes the lever 105c to rotate. The lever 105c then rotates the support column 105b, which in turn rotates the baffle 105d, changing the baffle 105d from a vertical position to a horizontal position. The mixing tank 104 is positioned such that the wastewater inside flows from the drain pipe 105a into the receiving plate 105e, and then is discharged into the soil by the conveying pipe 105f. The two ends of the torsion spring 105h are fixed to the lever 105c and the drain pipe 105a respectively. When the mixing tank 104 moves upward, the return force of the torsion spring 105h drives the lever 105c to rotate in the opposite direction. The lever 105c drives the support column 105b to rotate, and the support column 105b drives the baffle 105d to change from a horizontal position to a vertical position, thereby blocking the drain pipe 105a and facilitating the subsequent mixing of wastewater. Example 3

[0046] Reference Figures 1-10 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0047] Specifically, the drive unit 202 includes a motor 202a and a threaded post 202b. The motor 202a is fixed inside the fixed box 201, and the threaded post 202b is fixed to the output end of the motor 202a. The top of the threaded post 202b is located inside the mixing box 104.

[0048] The output of motor 202a drives the threaded column 202b to rotate, and the threaded column 202b drives the mixing component 203 and the adjusting component 205 to rotate, thereby stirring and mixing the sewage and chemicals inside the mixing tank 104.

[0049] The mixing component 203 includes a fixed sleeve 203a, a sleeve 203b, a bracket 203c, a stirring blade 203d, and a fixed column 203e. The fixed sleeve 203a is fixed inside the mixing box 104, the sleeve 203b is sleeved on the outside of the threaded column 202b, the bracket 203c is fixed on the outside of the sleeve 203b, the stirring blade 203d is fixed at the bottom of the bracket 203c, and the fixed column 203e is fixed on the inside of the sleeve 203b.

[0050] By setting the fixed sleeve 203a, the agent inside the mixing tank 104 is prevented from flowing out from the connection of the sleeve 203b. By setting the bracket 203c, the stirring blade 203d is installed, so that when the sleeve 203b rotates, the bracket 203c rotates, and the bracket 203c drives the stirring blade 203d to rotate, thereby mixing the sewage and agent inside the mixing tank 104.

[0051] The limiting component 204 includes a movable column 204a, a limiting block 204b, a second spring 204c, a connecting block 204d, a stop block 204e, and a connecting column 204f. The movable column 204a is movably connected inside the movable block 103f. The limiting block 204b is fixed to one end of the movable column 204a. The second spring 204c is sleeved on the outside of the movable column 204a. The connecting block 204d is fixed to one side of the fixed plate 103j. The stop block 204e is fixed on the connecting block 204d. The connecting column 204f is located on one side of the connecting plate 103e.

[0052] When the connecting plate 103e moves, it drives the connecting column 204f to move. The connecting column 204f drives the limiting block 204b to move, and the limiting block 204b drives the movable block 103f to move. After the movable block 103f moves downward, the positioning column 103i flows from the connecting pipe 103b into the liquid outlet pipe 103c, thereby discharging the agent.

[0053] The adjusting component 205 includes a threaded sleeve 205a, a retaining ring 205b, a positioning block 205c, an insert block 205d, a positioning plate 205e, and a third spring 205f. The threaded sleeve 205a is threadedly connected to the outside of the threaded post 202b. The retaining ring 205b is sleeved on the outside of the threaded sleeve 205a. The positioning block 205c is fixed to one side of the retaining ring 205b. The insert block 205d is movably connected inside the positioning block 205c. The positioning plate 205e is fixed to the top of the insert block 205d. The third spring 205f is fixed to one side of the positioning plate 205e.

[0054] When the mixing box 104 moves up and down, the insert block 205d is inserted into the threaded sleeve 205a, causing the threaded sleeve 205a to rotate with the threaded post 202b. This causes the mixing box 104 to move the positioning block 205c, the insert block 205d, the positioning plate 205e, and the third spring 205f downward. Then, the bottom of the insert block 205d is in contact with the second insert plate 205h, thereby allowing the liquid medicine inside the mixing box 104 to be discharged.

[0055] The adjusting component 205 also includes a first insert plate 205g and a second insert plate 205h. The first insert plate 205g is disposed at the bottom of the mixing box 104, and the second insert plate 205h is fixed to the inner bottom wall of the box body 101.

[0056] One end of the first insert plate 205g and the second insert plate 205h are both inclined. The top of the insert block 205d is provided with a slot that cooperates with the first insert plate 205g and the second insert plate 205h. The positioning block 205c can be pushed by the cooperation of the first insert plate 205g, the second insert plate 205h and the slot.

[0057] In use, the wastewater filtered by the filter screen 102c is first transported to the inlet tank 102b through the fixed pipe 102a. Both sides of the inlet tank 102b are provided with through slots that are connected to the fixed pipe 102a. There are three fixed pipes 102a, all of which are fixed to the outside of the box body 101. The fixed pipes 102a on both sides of the box body 101 are fixed at an angle to facilitate the flow of wastewater into the inlet tank 102b. The inlet tank 102b transports the wastewater to the mixing tank 104 for subsequent mixing of wastewater and chemical agents.

[0058] The mixing tank 104 is limited by the connecting plate 103e, thereby allowing the mixing tank 104 to move vertically up and down. The top of the positioning column 103i is located inside the connecting pipe 103b. The movable block 103f drives the positioning column 103i to move downward, causing the top of the positioning column 103i to move downward. This allows the chemical agent inside the reagent tank 103a to flow into the outlet pipe 103c through the connecting pipe 103b. The outlet pipe 103c then transports the chemical agent into the mixing tank 104. The output end of the motor 202a drives the threaded column 202b to rotate. The threaded column 202b drives the threaded sleeve 205a to rotate. The top of the threaded sleeve 205a is fixed to the sleeve 203b and drives the sleeve 203b to rotate. When the sleeve 203b rotates, it drives the support 203c to rotate. The support 203c drives the stirring blade 203d to rotate, thereby mixing the sewage and the chemical agent inside the mixing tank 104.

[0059] When the purified wastewater is discharged, the mixing tank 104 moves downward, which in turn moves the drain pipe 105a. The drain pipe 105a then moves the support column 105b, the lever 105c, and the baffle 105d, causing the bottom of the lever 105c to contact the fixing block 105g. The fixing block 105g limits the lever 105c's rotation, which in turn rotates the support column 105b. The support column 105b then rotates the baffle 105d, changing it from a vertical to a horizontal position. This allows the mixing tank 104 to move downward. The sewage inside flows into the receiving plate 105e from the drain pipe 105a, and then is discharged into the soil by the conveying pipe 105f. The two ends of the torsion spring 105h are fixed to the lever 105c and the drain pipe 105a respectively. When the mixing box 104 moves upward, the return spring force of the torsion spring 105h drives the lever 105c to rotate in the opposite direction. The lever 105c drives the support column 105b to rotate. The support column 105b drives the baffle 105d to change from a horizontal position to a vertical position, thereby blocking the drain pipe 105a and facilitating the subsequent mixing of sewage.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
