DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Embodiment: A wastewater treatment device based on aeration treatment, such as Figure 1 and Figure 2As shown, it includes a bottom plate 1, a mounting frame 2, a tank body 3, a mesh plate 301, a water inlet pipe 4, a water outlet pipe 5, an electric control valve I 6, a water pump I 7, a connecting pipe 8, a waste pipe 9 and an electric control valve II 10. The mounting frame 2 is connected to the right side of the top surface of the bottom plate 1, and the tank body 3 is connected to the lower part of the mounting frame 2. The height of the bottom surface of the tank body 3 gradually decreases from the surrounding to the center position, so as to facilitate the discharge of the clear liquid on the bottom surface of the tank body 3. The middle part of the inner side of the tank body 3 is symmetrically connected with the mesh plate 301, and the mesh plate 301 is inclined. The mesh plate 301 can divide the internal space of the tank body 3 into upper and lower layers. The quartz sand filler is laid on the top surface of the mesh plate 301, that is, it is located in the upper space inside the tank body 3. Since the mesh plate 301 is a porous structure, the clear liquid filtered by the quartz sand filler can flow through the mesh plate 301 to the lower space inside the tank body 3, and the pore size of the mesh plate 301 is larger than the particle size of the quartz sand filler. The quartz sand filler cannot fall into the lower space inside the tank body 3 through the mesh plate 301, so that the mesh plate 301 can provide support for the quartz sand filler without affecting the quartz sand filler's filtering work on wastewater; the water inlet pipe 4 is connected to the left side of the top surface of the tank body 3, and the water outlet pipe 5 is connected to the middle of the bottom surface of the tank body 3. The water inlet pipe 4 and the water outlet pipe 5 are both installed with an electric control valve Ⅰ6. The water pump Ⅰ7 is installed on the left front side of the top surface of the bottom plate 1. The water inlet and water outlet of the water pump Ⅰ7 are connected with connecting pipes 8. There are two connecting pipes 8. The front ends of the two connecting pipes 8 are connected to the outlet pipe 5, and the two connecting pipes 8 are respectively located on the left and right sides of the electric control valve Ⅰ6 on the outlet pipe 5. The waste pipe 9 is connected to the left front side of the top surface of the bottom plate 1, and the upper end of the waste pipe 9 is connected to the water inlet pipe 4. The upper end of the waste pipe 9 is located on the right side of the electric control valve Ⅰ6 on the inlet pipe 4, and the electric control valve Ⅱ10 is installed on the waste pipe 9.

[0028] Initially, a sufficient amount of quartz sand filler is laid on the top surface of the mesh plate 301, and the left end of the water inlet pipe 4 is connected to the wastewater tank, the left end of the water outlet pipe 5 is connected to the water storage tank, and the electric control valve I6 and the electric control valve II10 are both in a closed state; first open the two electric control valves I6, and then the wastewater in the wastewater tank can be passed into the tank body 3 through the water inlet pipe 4. Since the electric control valve II10 is in a closed state, the wastewater will not enter the waste discharge pipe 9, and the quartz sand filler in the tank body 3 can remove suspended matter and particulate impurities in the wastewater therein, and play a filtering role. The filtered clear liquid will fall down through the mesh plate 301 to the lower space inside the tank body 3, and then the clear liquid will be discharged into the water storage tank through the water outlet pipe 5 for storage; after the quartz sand filler has been used for a period of time, dirt will adhere to its surface. At this time, the two electric control valves I6 can be closed , so that the sewage in the wastewater pool no longer flows into the tank body 3, and then the electric control valve II10 is opened, and the water pump I7 is controlled to start working. The water pump I7 can extract the clear liquid in the water storage tank and transport it to the outlet pipe 5, and send the clear liquid into the tank body 3 through the outlet pipe 5, so that the clear liquid can surge upward from the bottom of the mesh plate 301 and fill the inside of the tank body 3. The quartz sand filler will become a little loose due to the upward thrust of the clear liquid. In this way, the quartz sand filler on the mesh plate 301 can be reversely flushed by the clear liquid to remove the dirt adhered to the surface of the quartz sand filler, and the dirt will flow to the water inlet pipe 4 with the clear liquid, and finally discharged out through the waste pipe 9, and collected and processed by the workers. After the quartz sand filler is flushed, the water pump I7 and the electric control valve II10 are turned off, and the electric control valve I6 is opened again, and the quartz sand filler can be used to filter the wastewater.

[0029] like Figure 3-Figure 6As shown, an aeration mechanism is also included, which includes a high-pressure air pump 11, an air supply pipe 12, a pulse solenoid valve 13, a vertical pipe 14, an agitation component and an anti-blocking component. The high-pressure air pump 11 is installed on the left rear side of the top surface of the bottom plate 1, the air supply pipe 12 is connected to the lower left part of the tank body 3, and the left end of the air supply pipe 12 is connected to the air outlet of the high-pressure air pump 11, the right part of the air supply pipe 12 is located in the lower space inside the tank body 3, and the overall shape of the right part of the air supply pipe 12 is annular, and the pulse solenoid valve 13 is installed on the air supply pipe 12. The pulse solenoid valve 13 is located at the bottom of the tank body 3. On the outside, vertical pipes 14 are symmetrically connected to the two mesh plates 301. There are four vertical pipes 14. The lower ends of the four vertical pipes 14 are connected to the right part of the air supply pipe 12. The stirring assembly is used to stir the quartz sand filler on the mesh plate 301, and the anti-blocking assembly is used to protect the stirring assembly; the stirring assembly includes a sliding pipe 15, a connecting spring 16 and a transverse pipe 17. The sliding pipe 15 is slidably connected to the upper end of the vertical pipe 14. The connecting spring 16 is located on the upper side of the vertical pipe 14, and the two ends of the connecting spring 16 are respectively connected to the sliding pipe 15 and the vertical pipe 14. The outer wall of the sliding tube 15 is connected with four transverse tubes 17 in a circumferentially spaced order from top to bottom, so that the overall shape of the sliding tube 15 and the transverse tube 17 is in the shape of a stirring rod, and the interior of the transverse tube 17 is connected to the interior of the sliding tube 15; the anti-blocking assembly includes a perforated plate 18, a sliding rod 19, a stopper 20, a return spring 21 and a protection frame 22, the middle of the transverse tube 17 is connected with a perforated plate 18, and a plurality of circular holes are spaced circumferentially on the perforated plate 18. The sliding rod 19 is slidably connected to the middle of the perforated plate 18, and the end of the sliding rod 19 away from the sliding tube 15 is connected A stopper 20 is connected, and the side of the stopper 20 is fitted with the side of the orifice plate 18 to block the round hole on the orifice plate 18. A reset spring 21 is wound around the outside of the sliding rod 19, and the two ends of the reset spring 21 are respectively connected to the side of the orifice plate 18 and the end of the sliding rod 19. A protective frame 22 is connected to the side of the transverse tube 17 away from the sliding tube 15. A gap is left between the outer wall of the protective frame 22 and the inner wall of the transverse tube 17 for compressed air to flow, and the outer wall of the stopper 20 is in sliding contact with the inner wall of the protective frame 22, and the internal space of the protective frame 22 can be used for the stopper 20 to slide.

[0030] Initially, the protection frame 22 covers the outside of the block 20, so as to block the quartz sand filler entering the horizontal pipe 17 and prevent excessive quartz sand filler from entering the horizontal pipe 17 and causing blockage; when the equipment is flushing the quartz sand filler, the high-pressure air pump 11 and the pulse solenoid valve 13 can be started, and the high-pressure air pump 11 can inject compressed air into the left end of the air supply pipe 12, and the pulse solenoid valve 13 can control the instantaneous opening and closing of the compressed air in the air supply pipe 12 to realize the pulse delivery of compressed air, so that the compressed air can be intermittently delivered to the vertical pipe 14 at high frequency. When there is compressed air transported upward in the vertical pipe 14, the sliding pipe 15 moves upward under the thrust of the compressed air, the connecting spring 16 is stretched, and then the compressed air can enter the horizontal pipe 17 along the sliding pipe 15. The compressed air in the horizontal pipe 17 pushes the stopper 20 and the sliding rod 19 to move away from the sliding pipe 15 through the round hole on the orifice plate 18. The return spring 21 is compressed so that the stopper 20 no longer blocks the round hole on the orifice plate 18. Then the compressed air can flow out through the gap between the outer wall of the protective frame 22 and the inner wall of the horizontal pipe 17. Since there is air coming out from the end of the horizontal pipe 17, the compressed air will flow out. The compressed air is used to make the quartz sand filler not enter the horizontal pipe 17. The compressed air emitted from the end of the horizontal pipe 17 can form bubbles inside the quartz sand filler, and the bubbles will gradually rise. When the quartz sand filler is flushed, the dirt on the surface of the quartz sand filler will be separated from the quartz sand filler. At this time, the bubbles can carry the dirt separated from the quartz sand filler and rise together, assisting the dirt to enter the sewage pipe 9 and be discharged outward. When there is no compressed air transported upward in the vertical pipe 14, the connecting spring 16 will return to its original state, driving the sliding pipe 15 to move downward and reset, and there is no compressed air in the horizontal pipe 17. Air, at this time the reset spring 21 will return to its original state, driving the stopper 20 and the sliding rod 19 to move and reset in the direction close to the sliding tube 15, so that the stopper 20 blocks the round hole on the orifice plate 18 again, preventing the quartz sand filler from entering the sliding tube 15 through the round hole on the orifice plate 18, and so on and so forth, the flushing efficiency and flushing effect of the quartz sand filler can be improved by aeration, and the sliding tube 15 can be made to reciprocate up and down, so that the quartz sand filler around it can be intermittently poked to stir it, so that the quartz sand filler moves slightly, which is convenient for the rise of bubbles.

[0031] like Figure 7As shown, it also includes a discharge frame 23, a discharge pipe 24, an electric control valve III 25, a screw feeder I 26 and a feeding assembly. The discharge frame 23 is connected between the sides of the bottom surfaces of the two mesh plates 301 that are close to each other. The discharge pipe 24 is connected to the bottom surface of the discharge frame 23, and the inside of the discharge pipe 24 is connected to the inside of the discharge frame 23. The electric control valve III 25 is installed at the left end of the discharge pipe 24, and the screw feeder I 26 is installed at the lower right part of the tank body 3. The screw rod of the screw feeder I 26 rotates and penetrates the side of the tank body 3, and the screw rod of the screw feeder I 26 is located in the discharge pipe 24. The feeding assembly is used to transport the quartz sand filler to the mesh plate 301; the feeding assembly includes a charging tank 27 , feed pipe 28, screw feeder II 29, discharge pipe 30 and electric control valve IV 31, the charging tank 27 is connected to the upper part of the mounting frame 2, the height of the inner bottom surface of the charging tank 27 gradually decreases from the surrounding to the center position, the feed pipe 28 is connected to the top surface of the tank body 3, the overall shape of the feed pipe 28 is an inverted L shape, so that the lower end of the feed pipe 28 passes through the top surface of the tank body 3, the lower end of the feed pipe 28 is located at the upper inner side of the tank body 3, the screw feeder II 29 is installed on the top surface of the tank body 3, and the screw rod of the screw feeder II 29 is located in the feed pipe 28, the two ends of the discharge pipe 30 are respectively connected to the middle of the bottom surface of the charging tank 27 and the right side of the top surface of the feed pipe 28, and the electric control valve IV 31 is installed on the discharge pipe 30.

[0032] The quartz sand filler has a service life. After the quartz sand filler has been used for a few years, it needs to be replaced. When replacing, the worker can put the new quartz sand filler into the charging tank 27, and then close the two electric control valves I6 to prevent the sewage in the wastewater pool from flowing into the tank body 3. Then open the electric control valve III 25 and the screw feeder I 26. The screw feeder I 26 can discharge the quartz sand filler in the discharge pipe 24. The quartz sand filler in the tank body 3 will gradually fall down into the discharge pipe 24 through the discharge frame 23 due to gravity, and then be discharged out along the discharge pipe 24. The worker Unified collection and processing; when the quartz sand filler in the tank body 3 is completely discharged, the electric control valve III 25 and the screw feeder I 26 can be closed, and the electric control valve IV 31 and the screw feeder II 29 can be opened. At this time, the quartz sand filler in the charging tank 27 will fall down into the feed pipe 28 through the discharge pipe 30, and then the screw feeder II 29 can transport the quartz sand filler in the feed pipe 28 downward into the tank body 3. After the quartz sand filler is replaced, the electric control valve IV 31 and the screw feeder II 29 can be closed, thereby automatically completing the replacement of the quartz sand filler in the tank body 3, saving time and effort.

[0033] like Figure 7 and Figure 8As shown, it also includes a water pump II 32, a shunt pipe 33 and a fixed pipe 34. The water pump II 32 is installed on the lower left side of the tank body 3. The water inlet of the water pump II 32 is connected to the inside of the tank body 3. The shunt pipe 33 is connected to the water outlet of the water pump II 32. A plurality of fixed pipes 34 are connected to the two mesh plates 301 at intervals, and the lower end of the fixed pipe 34 is connected to the shunt pipe 33. The upper end of the fixed pipe 34 is also provided with an anti-blocking component.

[0034] Initially, since an anti-blocking component is also provided at the upper end of the fixed pipe 34, the quartz sand filler can be prevented from entering the fixed pipe 34 and causing blockage; when the quartz sand filler in the tank body 3 needs to be replaced, only the two electrically controlled valves Ⅰ6 need to be closed so that the sewage in the wastewater pool no longer flows into the tank body 3. At this time, some clear liquid will remain in the lower space inside the tank body 3. At this time, the water pump Ⅱ32 can be started, and the water pump Ⅱ32 can transport the above clear liquid to the shunt pipe 33. The clear liquid in the shunt pipe 33 will flow into each fixed pipe 34 respectively. At this time, the clear liquid will emerge from the upper end of the fixed pipe 34 through the anti-blocking component, so that the clear liquid can flow downward along the mesh plate 301, and then the quartz sand filler on the top surface of the mesh plate 301 can be washed down, and the auxiliary quartz sand filler falls down into the discharge frame 23. In this way, the quartz sand filler can be prevented from remaining on the top surface of the mesh plate 301, ensuring that the quartz sand filler can be completely replaced.

[0035] like Fig. 9 As shown, it also includes a connecting frame 35, a rotating rod 36, a rotating tube 37 and a right-angle gear box 38. The connecting frame 35 is connected to the lower left side of the feed pipe 28, the rotating rod 36 is rotatably connected to the middle of the connecting frame 35, and the rotating tube 37 is rotatably connected to the lower end of the feed pipe 28. The rotating tube 37 is located inside the tank body 3, and the inner wall of the rotating tube 37 is connected to the lower end of the rotating rod 36. The right-angle gear box 38 is installed on the left side of the feed pipe 28. Two bevel gears are arranged inside the right-angle gear box 38, and the two bevel gears are perpendicular to each other and mesh with each other. The two bevel gears are respectively connected to the upper end of the rotating rod 36 and the left part of the screw rod of the screw feeder II 29.

[0036] When the screw feeder II 29 transports the quartz sand filler in the feed pipe 28 downward, the quartz sand filler in the feed pipe 28 will first flow into the rotating tube 37, and then the quartz sand filler in the rotating tube 37 will fall downward into the tank body 3. At the same time, the screw feeder II 29 can drive the rotating rod 36 to rotate through the right-angle gear box 38, and the rotating rod 36 can drive the rotating tube 37 to rotate, so that the rotating tube 37 can spread the quartz sand filler on the top surface of the mesh plate 301 to ensure the subsequent filtration of the wastewater by the quartz sand filler.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
