Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of wastewater treatment equipment, and in particular relates to a treatment device for mining wastewater. Background Technology
[0002] Mining operations generate a lot of wastewater containing impurities. This wastewater needs to be filtered and separated by treatment equipment before it can be discharged in an environmentally friendly manner.
[0003] In the prior art, such as the Chinese patent (CN220116390U) which discloses a treatment device for mining wastewater, belonging to the field of wastewater treatment technology, the filtration mechanism includes a filter chamber fixedly installed on the outside of a vertical plate, with a rotating wheel rotatably arranged inside the filter chamber; the purification mechanism includes a vertical support frame fixedly installed on the outer wall of the purification chamber, with a horizontal support frame at the top of the vertical support frame; a swing plate is movably arranged on the inner side of the vertical support frame, a sleeve is slidably arranged on a sliding rod one, a lifting seat is slidably arranged on a sliding rod two, a swing block is movably arranged on the outside of the hanging plate, and the inner side of the swing block is movably connected to the swing plate; the inner side of the lifting seat is movably connected to the swing block through a swing rod.
[0004] This method has the following drawbacks: First, when the device filters debris from wastewater, during the process of the flap lifting the debris and sending it to the discharge port, the debris located on the flap that is far from the outlet cannot be discharged from the discharge port in time. As the flap continues to rise, the debris is sent back inward by gravity. This repeated process causes the debris to accumulate inside the device, resulting in low filtration efficiency. Second, the device filters and separates sediment from filtered water through side filter holes. However, the position and area of the filter holes affect the filtration efficiency of the device. If the holes are located higher and have a smaller area, they are less affected by sediment but have lower filtration efficiency. If the holes are located lower and have a larger area, they have higher filtration efficiency but are more affected by sediment. Third, the flat surface at the bottom of the device cannot completely drain the sediment. Some sediment will remain on the bottom surface when the filtered water is drained.
[0005] Therefore, this paper provides a treatment device for mining wastewater. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Example
[0025] like Figures 1 to 6 As shown:
[0026] The prior art in this embodiment has the following problems: The inventors have found the following defects in the prior art: 1. When the device filters debris from wastewater, during the process of the flap flipping up and lifting the debris to the discharge port, the debris located on the flap that is far from the outlet cannot be discharged from the outlet in time. As the flap continues to lift upward, the debris is sent back inward by gravity. This repeated process causes the debris to accumulate inside the device, resulting in low efficiency in filtering debris. 2. The device filters and separates sediment and filtered water through the side filter holes 15. However, the position and area of the filter holes affect the filtration efficiency of the device. If the position is higher and the area is smaller, it is less affected by sediment, but the filtration efficiency is low. If the position is lower and the area is larger, the filtration efficiency is high, but the filter holes are more affected by sediment. 3. The flat surface at the bottom of the device cannot completely drain the sediment. When the filtered water is drained, some sediment will remain on the bottom surface.
[0027] Therefore, the inventor provides a treatment device for mining wastewater, including a device body and a controller 1. The controller 1 is located on the front side of the device body and is electrically connected to the device body. The device body also includes a crushing and filtering device, a dosing device, and a sedimentation and separation device. The crushing and filtering device is located on the left side of the dosing device, and the sedimentation and separation device is located below the dosing device. The crushing and filtering device also includes a cylinder 2, a drive motor 3, an auger blade 4, a slag discharge port 5, a waste bin 6, a feed inlet 7, and a water outlet a8. The cylinder 2 is inclined on the left side of the dosing device. The drive motor 3 is located at the top left side of the cylinder 2. The auger blade 4 is located inside the cylinder 2, and the top of the auger blade 4 is connected to the lower output end of the drive motor 3. The slag discharge port 5 is located on the lower left side of the cylinder 2. The waste bin 6 is located below the slag discharge port 5. The feed inlet 7 is located in the upper middle part of the cylinder 2. The water outlet a8 is located on the right side of the cylinder 2 and is connected to the side rear inlet of the dosing device.
[0028] Using the above scheme, wastewater enters the device from above the crushed stone filtration device. After filtration, the crushed stone is conveyed upwards and discharged. The filtered wastewater then enters the dosing device downwards. In the dosing device, the wastewater is mixed evenly with the precipitant by centrifugal force and then discharged downwards into the sedimentation separation device. After sedimentation separation, the precipitate is separated from the filtered water. Example
[0029] like Figures 1 to 6 As shown:
[0030] Furthermore, the surface of the auger blade 4 is provided with holes 9;
[0031] Furthermore, a cleaning strip (not shown in the figure) is provided inside the cylinder 2 on the front side of the slag discharge port 5 to fit the screw conveyor blades 4.
[0032] Wastewater enters the cylinder 2 through the feed inlet 7 and is filtered through the holes 9 on the auger blades 4, leaving the gravel on the blades 4. The holes 9 can be set to be uniform or irregular depending on the amount of gravel in the filtered wastewater to increase the filtration effect. The filtered wastewater is discharged downward through the holes 9 from the outlet a8 to the dosing device. During the filtration process, the drive motor 3 drives the auger blades 4 to rotate, carrying the filtered gravel upward to the slag discharge port 5 and then downward. The cleaning strip on the side of the slag discharge port 5 can brush off the gravel adhering to the auger blades 4. The cleaning strip can be made of rubber, which is durable and has a good cleaning effect. This ensures the separation efficiency of the device while separating gravel and wastewater. Example
[0033] like Figures 1 to 6 As shown:
[0034] Furthermore, the dosing device also includes a mixing tank 10, a dosing box 11, an electric valve 12, and an outlet b13. The mixing tank 10 is located to the right of the outlet a8. The dosing box 11 is located above the mixing tank 10 via a pipe. The electric valve 12 is located on the pipe between the dosing box 11 and the mixing tank 10. The outlet b13 is located below the mixing tank 10.
[0035] In this process, after the wastewater is filtered to remove the gravel, it enters from the rear side of the mixing tank 10 and rotates downwards along the side of the mixing tank 10 before being discharged. During this process, the controller 1 controls the electric valve 12 to open, allowing the precipitant in the dosing tank 11 to be discharged downwards. As the wastewater rotates, it is mixed by the centrifugal force of the wastewater and then discharged downwards into the sedimentation and separation device. This method ensures that the precipitant and wastewater are mixed evenly while saving the step of setting up a separate dosing and mixing mechanism, making it simple and efficient. Example
[0036] like Figures 1 to 6 As shown:
[0037] Furthermore, the sedimentation separation device also includes a housing 14, filter holes 15, a water collection tank 16, a linear motor 17, a cleaning rod 18, a drain pipe 19, and a sewage pipe 20. The housing 14 is located below the water outlet b13. The filter holes 15 are respectively located on the front and rear sides of the housing 14. The water collection tank 16 is respectively located on the front and rear sides of the filter holes 15. The linear motor 17 is respectively located on the front and rear sides of the top of the housing 14. The cleaning rod 18 is located below the slider on the side of the linear motor 17. The drain pipe 19 is respectively located on the right side of the water collection tank 16. The sewage pipe 20 is respectively located on the right side of the housing 14.
[0038] Furthermore, the housing 14 also includes a sedimentation chamber 21 and a filter chamber 22. The sedimentation chamber 21 is located inside the rear side of the housing 14 and below the outlet b13. The filter chamber 22 is located in front of the sedimentation chamber 21, and the volume of the filter chamber 22 is smaller than that of the sedimentation chamber 21.
[0039] Furthermore, the housing 14 is provided with a sewage hopper 23, which has a structure that tapers downward and tilts to the right at the bottom;
[0040] The wastewater after chemical dosing enters the sedimentation chamber 21 from the outlet b13. After initial sedimentation in the sedimentation chamber 21, the sediment accumulates in the lower sludge hopper 23. Some of the filtered water is discharged from the side filter holes 15 to the collection tank 16, and then discharged from the drain pipe 19 through the collection tank 16. Because there is a lot of sediment entering the sedimentation chamber 21, the sediment will block the filter holes 15. Therefore, the controller 1 controls the linear motor 17 to drive the cleaning rod 18 to brush the surface of the filter holes 15 to ensure filtration efficiency. Most of the upper clear water enters the filter chamber 22 inside the tank 14. The treated water in the filter chamber 22 is also discharged through the filter holes 15 and the collection tank 16. A linear motor 17 and a cleaning rod 18 are also provided. However, after the preliminary filtration and separation in the sedimentation chamber 21, less sediment enters the filter chamber 22, and the filtration efficiency is higher. This separation filtration method improves the filtration efficiency of the device. The filtered sediment accumulates in the lower sludge hopper 23. As the filtered water flows out, it accumulates to the right side of the sludge hopper 23 and is discharged to the right through the sludge pipe 20 to prevent sediment from accumulating at the bottom of the device and to ensure the sludge discharge effect.
[0041] In summary, the device is equipped with a crushed stone filtration unit, which filters wastewater downwards while simultaneously conveying crushed stone upwards and discharging it downwards, ensuring the separation efficiency of the device while separating the crushed stone from the wastewater. A sedimentation separation mechanism is also included to perform preliminary separation of the wastewater after chemical dosing, retaining most of the sediment inside the sedimentation chamber 21, while the treated water with less sediment enters the filtration chamber 22 for filtration, thus improving the filtration rate of the device. A sludge discharge hopper 23 is installed at the bottom of the device to prevent sediment from accumulating at the bottom and ensure effective sludge discharge.
[0042] The working principle of this utility model:
[0043] Wastewater enters the device from above the crushed stone filter and is filtered through the holes 9 on the auger blades 4, leaving the crushed stone on the auger blades 4. The holes 9 can be set to be uniform or irregular depending on the amount of crushed stone in the filtered wastewater to increase the filtration effect. The filtered wastewater is discharged downward through the holes 9 from the outlet a8 to the dosing device. During the filtration process, the drive motor 3 drives the auger blades 4 to rotate, carrying the filtered crushed stone upward to the slag discharge port 5 and then downward. The cleaning strip on the side of the slag discharge port 5 can brush off the crushed stone attached to the auger blades 4. This can ensure the separation efficiency of the device while separating the crushed stone from the wastewater.
[0044] After the wastewater is filtered to remove the gravel, it enters from the rear side of the mixing tank 10 and rotates downwards along the side of the tank body to be discharged. During the process, the controller 1 controls the electric valve 12 to open, so that the precipitant in the dosing tank 11 is discharged downwards. During the rotation of the wastewater, it is mixed by the centrifugal force of the wastewater and then discharged downwards into the sedimentation and separation device. This method can save the step of setting up a separate dosing and mixing mechanism while ensuring that the precipitant and wastewater are evenly mixed. It is simple and efficient.
[0045] After chemical dosing, the wastewater flows downwards from outlet b13 into sedimentation chamber 21. After initial sedimentation in sedimentation chamber 21, the sediment accumulates in the lower sludge hopper 23. Some filtered water is discharged from the side filter holes 15 into the collection tank 16, and then discharged through the drain pipe 19. Due to the large amount of sediment entering sedimentation chamber 21, the sediment will clog the filter holes 15. Controller 1 controls linear motor 17 to drive cleaning rod 18 to brush the surface of the filter holes 15 to ensure filtration efficiency. Most of the upper clear water enters the filter chamber 22 inside the tank 14 for filtration. The treated water in chamber 22 is also discharged through the filter hole 15 and the collection tank 16. A linear motor 17 and a cleaning rod 18 are also provided. However, after the preliminary filtration and separation in the sedimentation chamber 21, less sediment enters the filter chamber 22, and the filtration efficiency is higher. In this way, the filtration efficiency of the device is improved by separation filtration. The filtered sediment accumulates in the lower sewage hopper 23. As the filtered water flows out, it accumulates to the right side of the sewage hopper 23 and is discharged to the right through the sewage pipe 20 to prevent sediment from accumulating at the bottom of the device and to ensure the sewage discharge effect.
[0046] This concludes the description of the working principle of the device.
