Description

Technical Field

[0001] This invention relates to the field of groundwater treatment technology, and more specifically, to the construction of groundwater treatment devices. Background Technology

[0002] A cavern is a warehouse built inside a rocky mountain, and is a type of underground engineering structure. The construction of water-sealed caverns is characterized by its large scale, complex engineering techniques, and high safety requirements. During the construction of water-sealed cavern projects, a significant amount of groundwater is generated, and any contaminated groundwater is treated and reused.

[0003] Currently, when treating groundwater during construction, it is necessary to pass the groundwater into a sedimentation tank for sedimentation. After the solid residues in the groundwater settle to the bottom, they are then separated from the groundwater. However, this method requires a long settling time, has low treatment efficiency, and some solids do not settle completely, resulting in poor separation and treatment of groundwater.

[0004] Therefore, it is necessary to provide groundwater treatment equipment to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a groundwater treatment device for construction to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The groundwater treatment system includes a treatment tank and also includes:

[0008] A separation chamber is located inside the processing tank. The processing tank has a water inlet communicating with the separation chamber on its rear side, and a control valve is installed inside the water inlet.

[0009] A filter plate is disposed inside the separation chamber and slidably attached to its surrounding inner walls, used to separate solids from wastewater within the separation chamber;

[0010] A drive mechanism, located on the processing box, is used to drive the filter plate to move up and down;

[0011] A water passage is provided inside the treatment tank and communicates with the separation chamber. Wastewater filtered by the filter plate is discharged through the water passage.

[0012] A baffle is provided inside the water passage hole to block the water passage hole. A linkage mechanism is provided at the corresponding position of the baffle in the treatment tank. After the filter plate moves down to the designated position, the linkage mechanism drives the baffle to move down, so that the water passage hole and the separation chamber are connected and the sewage is discharged through the water passage hole.

[0013] As a further embodiment of the present invention: the linkage mechanism includes a movable inner groove and a movable outer groove opened in the processing box, the movable inner groove is provided with a first elastic member connected to the baffle, and the movable outer groove is provided with a movable plate connected to the baffle.

[0014] The side wall of the separation chamber is provided with a sliding groove corresponding to the position of the movable outer groove. A pressure rod connected to the side wall of the filter plate is slidably arranged in the sliding groove. A pressing block that cooperates with the pressure rod is provided on the movable plate.

[0015] As a further aspect of the present invention: the interior of the processing tank is provided with a liquid storage chamber and a reaction tank that communicate with the water passage, and the liquid storage chamber and the water passage are connected through a liquid outlet.

[0016] As a further aspect of the present invention: a rotating shaft is rotatably connected inside the water passage hole, and a fan blade is provided on the rotating shaft; the liquid outlet hole is located between the baffle and the fan blade.

[0017] As a further aspect of the present invention: the end of the rotating shaft is provided with an incomplete gear, and a blocking plate is movably provided on the inner wall of the water passage at the position corresponding to the liquid outlet. The blocking plate is provided with two connecting holes corresponding to the liquid outlet, and the blocking plate is provided with a rack that intermittently meshes with the incomplete gear.

[0018] As a further aspect of the present invention: a movable groove is provided on the inner wall of the water passage at the position corresponding to the blocking plate, a slider connected to the blocking plate is slidably connected in the movable groove, and a second elastic element is provided between the slider and the inner wall of the movable groove.

[0019] As a further aspect of the present invention: the driving mechanism includes a lead screw rotatably connected to the upper wall of the separation chamber, and a driving component for rotating the lead screw is provided at the top of the processing box at the position corresponding to the lead screw. The lead screw is threadedly connected to the filter plate.

[0020] As a further embodiment of the present invention: the side wall of the processing box is provided with a discharge port, the discharge port is provided with a sealing plate, and the side wall is provided with a first telescopic member connected to the sealing plate;

[0021] A push plate is provided inside the separation chamber on one side of the water inlet, and a second telescopic component connected to the push plate is provided inside the treatment box.

[0022] As a further aspect of the present invention, it also includes a collection box, which has an inlet communicating with the discharge port, and a filter screen inside the collection box that can separate solids from wastewater.

[0023] As a further aspect of the present invention, it also includes a pump body, wherein the inlet and outlet of the pump body are provided with water pipes, and the two water pipes are respectively connected to the bottom of the collection tank and the treatment tank.

[0024] Compared with the prior art, the advantages of this invention are:

[0025] 1. This solution uses a driving mechanism to move the filter plate down along the inner wall of the separation chamber. As the filter plate gradually moves down, solid residues in the sewage move down and eventually accumulate between the filter plate and the bottom of the separation chamber, thus achieving the separation of solid residues from underground sewage. Simultaneously, as the filter plate descends, a linkage mechanism moves the baffle down, opening the water passage and allowing the sewage to drain away. This achieves the discharge of sewage after separation of sewage and solid residues, avoiding the long time required for current static sedimentation. It has high treatment efficiency for underground sewage and greatly avoids the situation where some solids are not completely settled, resulting in good separation and treatment effects.

[0026] 2. In this solution, the wastewater discharged through the water inlet will drive the fan blades to rotate. The fan blades, through the incomplete gear and rack mechanism, will move the blocking plate and the connecting hole. At this time, the connecting hole will gradually align with the liquid outlet, meaning that the reaction solution in the storage chamber will enter the water inlet through the liquid outlet and mix with the incoming wastewater, thus further reacting and treating the wastewater. At the same time, the rotation of the fan blades will make the mixing more uniform and thorough, resulting in good wastewater treatment effect. No manual liquid addition is required, saving time and labor, and improving treatment efficiency. This further enhances the wastewater treatment performance and makes it highly practical.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1:

[0038] Please see Figure 1-3 and Figure 5-6 The groundwater treatment device includes a treatment tank 1, and further includes: a separation chamber 2 located inside the treatment tank 1, with an inlet 33 on the rear side of the treatment tank 1 communicating with the separation chamber 2, and a control valve inside the inlet 33; a filter plate 3 located inside the separation chamber 2 and slidingly attached to its surrounding inner walls, used to separate solids from sewage in the separation chamber 2; a drive mechanism 4 located on the treatment tank 1, used to drive the filter plate 3 to move up and down; a water passage hole 5 located inside the treatment tank 1 and communicating with the separation chamber 2, through which sewage filtered by the filter plate 3 is discharged; and a baffle 6 located inside the water passage hole 5, used to block the water passage hole 5. A linkage mechanism 7 is provided at the corresponding baffle 6 in the treatment tank 1. After the filter plate 3 moves down to a designated position, the linkage mechanism 7 drives the baffle 6 to move down, so that the water passage hole 5 and the separation chamber 2 are connected, allowing sewage to be discharged through the water passage hole 5.

[0039] In use, groundwater from construction is introduced into the separation chamber 2 inside the treatment tank 1 through the rear inlet. After the water is introduced, the filter plate 3 moves downward along the inner wall of the separation chamber 2 via the drive mechanism 4. The wastewater in the separation chamber 2 passes through the filter plate 3, while solid residues are blocked by the filter plate 3. As the filter plate 3 gradually moves downward, the solid residues in the wastewater move downward and eventually accumulate on the lower side of the separation chamber 2, that is, between the filter plate 3 and the bottom of the separation chamber 2. This achieves the removal of solid residues from the groundwater. The separation of sludge is achieved by simultaneously moving the baffle 6 downwards via the linkage mechanism 7 when the filter plate 3 descends. At this time, the water passage 5 is opened, and the separated sewage in the separation chamber 2 is discharged through the water passage 5. This achieves the discharge of sewage after the separation of sewage and solid residue, resulting in good performance. It avoids the long time required for current static sedimentation, has high efficiency in treating underground sewage, and ensures that the solid residue is located below the filter plate 3, greatly avoiding the situation where some solids are not completely settled. The separation and treatment effect is good.

[0040] In this embodiment, preferably, please refer to [reference needed]. Figure 1-3 The drive mechanism 4 includes a lead screw 41 rotatably connected to the upper wall of the separation chamber 2. A drive component 42 is provided at the corresponding position of the lead screw 41 on the top of the processing box 1 to drive its rotation. The lead screw 41 is threadedly connected to the filter plate 3. When the drive component 42 is activated, it drives the lead screw 41 to rotate. Since the filter plate 3 is rectangular and is restricted by the inner wall of the separation chamber 2, the rotation of the lead screw 41 will drive the filter plate 3 to move, causing the filter plate 3 to move downward along the inner wall of the separation chamber 2.

[0041] In this embodiment, preferably, please refer to [reference needed]. Figure 5-6 The linkage mechanism 7 includes a movable inner tank 71 and a movable outer tank 72 located within the treatment tank 1. The movable inner tank 71 contains a first elastic element 73 connected to a baffle 6, and the movable outer tank 72 contains a movable plate 74 connected to the baffle 6. The side wall of the separation chamber 2 has a sliding groove 8 corresponding to the position of the movable outer tank 72. A pressure rod 9 connected to the side wall of the filter plate 3 slides within the sliding groove 8. The movable plate 74 has a pressing block 10 that cooperates with the pressure rod 9. During its up-and-down movement, the movable plate 74 can completely block the movable inner tank 71, greatly preventing sewage and solid residue from the separation chamber 2 from entering the movable inner tank 71 and causing blockage, thus improving the efficiency of use.

[0042] Example 2:

[0043] Based on Example 1, please refer to Figure 3-4 and Figure 7The treatment tank 1 has a storage chamber 11 and a reaction tank 12 connected to the water passage 5. The storage chamber 11 and the water passage 5 are connected by an outlet 13. A rotating shaft 14 is rotatably connected inside the water passage 5, and a fan blade 15 is mounted on the rotating shaft 14. The outlet 13 is located between the baffle 6 and the fan blade 15. When the wastewater passes through the water passage 5, it mixes and reacts with the liquid medicine flowing down from the storage chamber 11. At the same time, the water flow drives the fan blade 15 to rotate, stirring the wastewater and further improving the mixing effect of the wastewater and the liquid medicine.

[0044] In this embodiment, preferably, please refer to [reference needed]. Figure 3-4 and Figure 7 An incomplete gear 16 is provided at the end of the rotating shaft 14. A blocking plate 17 is movably provided at the position of the corresponding liquid outlet 13 on the inner wall of the water passage 5. The blocking plate 17 has two connecting holes 18 corresponding to the liquid outlet 13. A rack 19 is provided on the blocking plate 17 to intermittently mesh with the incomplete gear 16. A movable groove 20 is provided at the position of the blocking plate 17 on the inner wall of the water passage 5. A slider 21 connected to the blocking plate 17 is slidably connected in the movable groove 20. A second elastic element 22 is provided between the slider 21 and the inner wall of the movable groove 20. The second elastic element 22 in this application is a spring. When the blocking plate 17 moves, it will drive the slider 21 to slide along the movable groove 20.

[0045] Wastewater discharged through water passage 5 flows through fan blade 15 into reaction tank 12. As water flows through fan blade 15, it rotates, causing the incomplete gear 16 to rotate. The incomplete gear 16 intermittently meshes with rack 19. When meshing with rack 19, it moves rack 19 and blocking plate 17. The movement of blocking plate 17 causes the connecting hole 18 to move, simultaneously compressing or stretching the second elastic element 22. Initially, the liquid outlet 13 is blocked by blocking plate 17, and the liquid storage chamber 11 is not connected to water passage 5. At this point, the connecting hole 18 will gradually align with the outlet hole 13. The storage chamber 11 will then connect to the water passage 5 via the outlet hole 13. This means the reaction solution in the storage chamber 11 will enter the water passage 5 through the outlet hole 13 and the connecting hole 18, mixing with the incoming wastewater for further reaction treatment. Simultaneously, the rotation of the fan blade 15 ensures more uniform and thorough mixing, resulting in excellent wastewater treatment. No manual addition is required, saving time and effort, and increasing treatment efficiency, further improving wastewater treatment performance and practicality. When no wastewater flows through the water passage 5, the fan blade 15 is no longer subjected to water flow force. The second elastic element 22 allows the blocking plate 17 and the connecting hole 18 to move to their initial positions. At this point, the blocking plate 17 will again block the outlet hole 13, preventing the solution in the storage chamber 11 from flowing down, greatly avoiding waste and meeting usage requirements.

[0046] When the incomplete gear 16 rotates to a point where it no longer meshes with the rack 19, the second elastic element 22 will cause the blocking plate 17 and the connecting hole 18 to return to their original positions, awaiting the next engagement. This not only allows the blocking plate 17 to move continuously but also allows the connecting hole 18 and the liquid outlet 13 to intermittently overlap, greatly reducing the waste of the reaction solution in the storage chamber 11 and resulting in good performance. The water passage 5 does not pass through sewage.

[0047] Example 3:

[0048] Based on Example 1, please refer to Figure 2-3 The processing tank 1 has a discharge port 23 on its side wall, and a sealing plate 24 is provided inside the discharge port 23. A first telescopic member 25 connected to the sealing plate 24 is provided inside the side wall. A push plate 26 is provided inside the separation chamber 2 on one side of the water passage 5. A second telescopic member 27 connected to the push plate 26 is provided inside the processing tank 1. Both the first telescopic member 25 and the second telescopic member 27 in this application are electric telescopic rods. The sealing plate 24 can then be moved upwards by the first telescopic member 25, at which point the discharge port 23 will be opened. Then, the push plate 26 will be extended and moved by the second telescopic member 27. Figure 3 Even if the push plate 26 moves to the left, it will cause the solid residue between the filter plate 3 and the separation chamber 2 to move, and finally discharge it out of the separation chamber 2 through the discharge port 23. This achieves the discharge of the solid residue after the separation of sewage and solid residue. The operation is convenient and efficient, and no manual waiting is required. It is highly practical.

[0049] It also includes a collection box 28, which has an inlet 29 communicating with the discharge port 23. The collection box 28 is equipped with a filter screen 30 that can separate solids and wastewater. When solid residue is discharged through the discharge port 23, it enters the collection box 28 through the inlet 29 and falls onto the filter screen 30. The collection box 28 can be opened to process the solid residue accumulated on the filter screen 30. Meanwhile, the wastewater pushed out from the separation chamber 2 and the residual wastewater in the solid residue will fall to the bottom of the collection box 28 through the filter screen 30, further achieving the separation of solids and wastewater, which facilitates subsequent treatment and is practical and convenient.

[0050] In this embodiment, preferably, please refer to [reference needed]. Figure 1 It also includes a pump body 31, with water pipes 32 at both the inlet and outlet of the pump body 31. The two water pipes 32 are connected to the bottom of the collection tank 28 and the treatment tank 1, respectively. By starting the pump body 31, the wastewater separated and filtered from the bottom of the collection tank 28 can be drawn out through the water pipes 32, and then discharged back into the treatment tank 1 for further separation and subsequent treatment, resulting in more thorough and effective treatment of underground wastewater.

[0051] Working principle: During use, the construction groundwater is introduced into the separation chamber 2 inside the treatment tank 1 through the inlet 33. After the introduction is completed, the control valve in the inlet 33 is closed, and the drive component 42 is started to drive the screw 41 to rotate. Since the filter plate 3 is rectangular and is restricted by the inner wall of the separation chamber 2, the screw 41 will drive the filter plate 3 to move when it rotates. At this time, the filter plate 3 moves down along the inner wall of the separation chamber 2. The water in the separation chamber 2 will pass through the filter plate 3, while solid residues will be blocked by the filter plate 3. As the filter plate 3 gradually moves down, the solid residues in the sewage will move down and eventually accumulate on the lower side of the separation chamber 2.

[0052] When the filter plate 3 descends, it simultaneously drives the pressure rod 9 to move down along the slide groove 8. When the filter plate 3 reaches the contact point with the pressure block 10, it continues to drive the pressure block 10 and the moving plate 74 down. The descent of the moving plate 74 causes the baffle 6 to move down, compressing the first elastic element 73. After the baffle 6 moves down, the water passage 5 is opened, allowing the separated wastewater in the separation chamber 2 to drain away through the water passage 5. Then, the sealing plate 24 can be moved upwards via the first telescopic element 25, opening the discharge port 23. The push plate 26 can then be extended and moved via the second telescopic element 27. Figure 3 Even if the push plate 26 moves to the left, it will cause the solid residue between the filter plate 3 and the separation chamber 2 to move, and finally discharge it out of the separation chamber 2 through the discharge port 23.

[0053] After solid residue is discharged through discharge port 23, it enters collection tank 28 through inlet 29. The solid residue falls onto filter screen 30. Collection tank 28 can be opened to process the solid residue accumulated on filter screen 30. Meanwhile, the wastewater pushed out from separation chamber 2 and the residual wastewater in the solid residue fall through filter screen 30 to the bottom of collection tank 28, further separating solids and wastewater for convenient subsequent treatment. It is practical and convenient. Afterwards, pump body 31 can be started to extract the wastewater separated and filtered from the bottom of collection tank 28 through water pipe 32, and then it can be discharged back into treatment tank 1 for separation and further treatment.

[0054] Wastewater discharged through water passage 5 flows through fan blade 15 into reaction tank 12. As water flows through fan blade 15, it rotates, causing the incomplete gear 16 to rotate. The incomplete gear 16 intermittently meshes with rack 19. When meshing with rack 19, it moves rack 19 and blocking plate 17. The movement of blocking plate 17 causes the connecting hole 18 to move, simultaneously compressing or stretching the second elastic element 22. Initially, the liquid outlet 1... When the liquid storage chamber 11 is blocked by the blocking plate 17, it is not connected to the water passage 5. At this time, the movement of the connecting hole 18 will gradually align it with the outlet hole 13. The liquid storage chamber 11 then connects to the water passage 5 through the outlet hole 13. This means the reaction solution in the liquid storage chamber 11 will enter the water passage 5 through the outlet hole 13 and the connecting hole 18, mixing with the incoming sewage for further reaction treatment. Simultaneously, the rotation of the fan blade 15 ensures more even and thorough mixing. When the incomplete gear 16 rotates to a point where it no longer meshes with the rack 19, the second elastic element 22 will drive the blocking plate 17 and the connecting hole 18 back to their original positions, awaiting the next engagement. The water passage 5 does not pass through sewage. When no sewage passes through the water passage 5, the fan blade 15 loses the driving force of the water flow. The second elastic element 22 will drive the blocking plate 17 to move, so that the connecting hole 18 returns to the initial position and blocks the liquid outlet 13, thus preventing the liquid in the storage chamber 11 from flowing out and being wasted.

[0055] After the underground sewage treatment is completed, the filter plate 3 is moved back to its initial position, and then the control valve on the inlet 33 is opened to open the inlet 33 for subsequent underground sewage treatment.
