[0025] 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.
[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] Reference Figure 1-6 As shown, this embodiment provides a mine wastewater recycling treatment system, including a filter box 1. A coarse filter assembly is provided at the top of the filter box 1. A diversion hopper 2 is symmetrically fixed to and connected to the bottom of the filter box 1. An aeration assembly is provided inside the diversion hopper 2. A partition plate 3 is fixed between the two diversion hoppers 2, located within the inner cavity of the filter box 1. Sedimentation tanks 4 are symmetrically fixed to both sides of the filter box 1. One end of the sedimentation tank 4 is open and communicates with the inner cavity of the filter box 1. A first mesh 5 is fixed to the open end of the sedimentation tank 4. A telescopic plate assembly is provided above the first mesh 5. There is a gap between the telescopic plate assembly and the open end of the sedimentation tank 4. One end of the telescopic plate assembly is movably connected to the side wall of the sedimentation tank 4. A reciprocating transmission assembly is provided in the partition plate 3. The ends of the two telescopic plate assemblies away from the sedimentation tank 4 are movably connected to the reciprocating transmission assembly. The bottom ends of the two diversion hoppers 2 are fixedly connected to and connected to a mixing tank 6. A dual-shaft motor 7 is fixedly installed on the top surface of the mixing tank 6. One output shaft of the dual-shaft motor 7 extends into the mixing tank 6 and is fixedly connected to a stirring assembly. The other output shaft of the dual-shaft motor 7 is fixedly connected to the reciprocating transmission assembly.
[0028] First, the coarse filter assembly initially filters out large particles of slag and other impurities from the wastewater. Then, the separator plate 3 divides the wastewater into two parts, allowing the diverted flow to fall onto two telescopic plate assemblies. Flocculant is added to flocculate the impurities. Then, the dual-shaft motor 7 drives the reciprocating transmission assembly, which in turn tilts the telescopic plate assembly, allowing the flocculated impurities to enter two sedimentation tanks 4. The first screen 5 intercepts the impurities, improving the filtration efficiency of the wastewater and facilitating impurity collection. The filtered wastewater flows into the mixing tank 6 through the two diversion hoppers 2, where chemicals are added. At the same time, the dual-shaft motor 7 drives the stirring assembly to mix the acid and alkali.
[0029] The scheme is further optimized. The coarse filter component includes rotating shafts 8 that are rotatably connected to the two sides of the top of the filter box 1. A filter conveyor belt 9 is connected between the two rotating shafts 8. Either rotating shaft 8 is driven by a first single-axis motor 10.
[0030] In a further optimized design, a collection frame 11 is fixedly connected to and connected to the side wall of the filter box 1. A second partition 12 is fixedly connected to the end of the collection frame 11 that is connected to the filter box 1. The collection frame 11 is located on one side of the filter conveyor belt 9, and the rotation direction of the filter conveyor belt 9 is towards the collection frame 11. A scraper 13 is fixedly connected to the top of the filter box 1 near the collection frame 11. The scraper 13 is inclined and abuts against the filter conveyor belt 9.
[0031] When wastewater is added to the filter box 1, it is first filtered by the filter conveyor belt 9. The filter conveyor belt 9 is driven by the first single-axis motor 10 to rotate between the two rotating shafts 8, so that the large particles of impurities intercepted on the filter conveyor belt 9 can be transferred to the collection frame 11. The collection efficiency can be improved by setting the scraper 13, and too many impurities can be avoided from sticking to the filter conveyor belt 9.
[0032] The scheme is further optimized. The telescopic plate assembly includes two first bearings 14. The two first bearings 14 are symmetrically fixed to the two side walls of the open end of the sedimentation tank 4. A shaft 15 is rotatably connected between the two first bearings 14. A main plate 16 is fixed to the shaft 15. A secondary plate 17 is slidably connected inside the main plate 16. The end of the secondary plate 17 near the partition plate 3 extends out of the main plate 16 and is movably connected to the reciprocating transmission assembly.
[0033] By using two first bearings 14 and shafts 15 to limit the end of the main plate 16 away from the secondary plate 17, the secondary plate 17 is moved by the reciprocating transmission assembly, and the secondary plate 17 drives the main plate 16 to move, so that the whole is tilted, allowing the flocculated material to slide into the sedimentation tank 4 for collection and sedimentation.
[0034] Furthermore, one end of the extension plate 17 extending from the main plate 16 is fixedly connected to the telescopic sealing strip 35, and the other end of the telescopic sealing strip is fixedly connected to the main plate 16. Thus, when the extension plate 17 extends and retracts along the main plate 16, the extension plate 17 and the side wall of the filter box 1 are kept sealed to prevent the leakage of debris and thus improve the filtration effect.
[0035] Further optimization of the scheme: the reciprocating transmission assembly includes a transmission groove 18, which is opened in the partition plate 3. A transmission rod 19 is rotatably connected in the transmission groove 18. The transmission rod 19 is fixedly connected to the output shaft of the dual-shaft motor 7 away from the stirring assembly. A reciprocating threaded groove 20 is opened on the transmission rod 19. A slider 21 is connected to the reciprocating threaded groove 20. Sliding grooves 22 are symmetrically opened on both sides of the transmission groove 18. A hinge seat 23 is slidably connected in the sliding groove 22. Both hinge seats 23 are fixedly connected to the slider 21. The ends of the two auxiliary plates 17 away from the main plate 16 are respectively hinged to the two hinge seats 23 through support rods 24.
[0036] The dual-axis motor 7 drives the transmission rod 19 to rotate, which in turn drives the slider 21 to reciprocate through the reciprocating threaded groove 20. The two hinge seats 23 can guide and limit the slider 21, thus realizing that the two hinge seats 23 slide synchronously with the slider 21 in the sliding groove 22, driving the main plate 16 and the secondary plate 17 to achieve the effect of reciprocating tilting, which facilitates the collection of flocculated impurities into the sedimentation tank 4.
[0037] Furthermore, the hinge end between the sub-plate 17 and the support rod 24 is arc-shaped to avoid interfering with the tilting movement of the sub-plate 17.
[0038] The aeration component is further optimized to include an aerator 25, which is fixedly installed on the outer wall of the diversion bucket 2. An aeration pipe 26 is fixedly connected to the aerator 25 and extends into the inner cavity of the diversion bucket 2.
[0039] The wastewater after flocculation is aerated and discharged through aerator 25 and aeration pipe 26.
[0040] Furthermore, a microbial layer 36 is circumferentially fixed to the inner wall of the diversion hopper 2 to facilitate aeration treatment.
[0041] The scheme is further optimized by fixing a guide pipe 27 to the bottom of the diversion hopper 2. The guide pipe 27 is fixed and connected to the mixing box 6. A first acidity detector 28 and a flow rate controller 29 are installed on the guide pipe 27.
[0042] The acidity or alkalinity of the wastewater in the two diversion hoppers 2 can be detected by the first acidity / alkalinity detector 28. The flow rate and volume between the diversion hopper 2 and the mixing tank 6 can be adjusted by the flow rate and volume controller 29 to achieve flow rate and volume control of wastewater with different acidity / alkalinity in the two diversion hoppers 2, which facilitates acid-base neutralization of the wastewater in the mixing tank 6.
[0043] The design is further optimized so that the stirring assembly includes a stirring rod 30, which is fixedly connected to the output shaft of the dual-shaft motor 7 away from the transmission rod 19, and a number of stirring blades 31 are fixedly connected to the stirring rod 30.
[0044] The wastewater treatment effect can be improved by driving the stirring rod 30 and stirring blade 31 to rotate by the dual-shaft motor 7. The side wall of the mixing tank 6 is fixedly connected to and connected to the dosing pipe 37, and the dosing pipe is equipped with a valve for easy dosing. The inner side wall of the mixing tank 6 is fixedly installed with a second pH detector 38 for easy detection of the pH of the mixed wastewater.
[0045] Further optimization of the scheme: the side wall of the mixing tank 6 is symmetrically fixed and connected to a circulation pipe 32, a water pump 33 is fixedly installed on the circulation pipe 32, the end of the circulation pipe 32 away from the mixing tank 6 is connected to the inner cavity of the filter box 1, and the connection end of the circulation pipe 32 and the filter box 1 is located between the main board 16 and the diversion hopper 2.
[0046] When the acidity or alkalinity of the wastewater in the mixing tank 6 is not up to standard, the wastewater can be introduced into the two diversion hoppers 2 through the water pump 33 and the circulation pipe 32, thereby readjusting the flow rate ratio of the two diversion hoppers 2.
[0047] The scheme is further optimized by symmetrically fixing and connecting flocculant addition pipes 34 to the side wall of filter box 1. The two flocculant addition pipes 34 are located on both sides of the partition plate and above the main board.
[0048] The flocculant can be easily added to the filter box 1 by setting up a flocculant addition pipe 34, and a valve is installed on the flocculant addition pipe 34.
[0049] Furthermore, the bottom of the mixing tank 6 is fixedly connected to and connected to an outlet pipe 43, which facilitates the discharge of treated wastewater for recycling.
[0050] Furthermore, the bottom surface of the sedimentation tank 4 is inclined, and a sewage discharge sleeve 39 is fixedly connected to the bottom surface of the sedimentation tank 4. One end of the sewage discharge sleeve 39 extends out of the sedimentation tank 4, and a sewage discharge pipe 40 is fixedly connected and connected to the side wall of the extended end. At the same time, a second single-axis motor 41 is fixedly installed at the end of the extended end, and a spiral conveying blade 42 located inside the sewage discharge sleeve 39 is fixedly connected to the output shaft of the second single-axis motor 41.
[0051] Thus, when it is necessary to discharge the impurities in the sedimentation tank 4, the second single-shaft motor 41 can drive the spiral conveying blades 42 to rotate, and the spiral conveying blades 42 can transport the impurities to the sewage pipe 40 for discharge.
