Description

Technical Field

[0001] The present invention relates to the technical field of filtration and purification, and particularly relates to a high-efficiency anaerobic wastewater flow-limiting structure. Background Art

[0002] An anaerobic reactor is a device for treating high-concentration organic wastewater through the metabolic action of microorganisms in anaerobic granular sludge. During the treatment process, in order to ensure the orderly entry of wastewater into the anaerobic reactor, a wastewater flow-limiting structure is usually set up to improve the treatment effect of wastewater.

[0003] For example, an efficient water distribution device for an anaerobic reactor with the publication number of CN218810823U in the prior art combines a flow control valve provided on the water inlet pipe and the sewage pipe with a turbidity sensor on the connecting pipe. Although it is convenient to adjust the flow ratio of water and sewage according to the turbidity of the wastewater, thereby optimizing the turbidity of the wastewater and improving the treatment effect of the anaerobic reactor, it is only through the way that the liquid is injected to impact the baffle plate and then contact and mix with the liquid level of the mixed liquid. It is difficult to ensure the full mixing of the later incoming wastewater and water before discharge, resulting in deviation of the detection results of the turbidity sensor and greatly affecting the treatment effect of the anaerobic reactor on the wastewater.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the Invention

Then, with the assistance of a scraping plate, the automatic discharge of impurities is realized to improve the cleaning convenience inside the cylinder, so as to solve the above-mentioned technical defects.

[0006] The purpose of the present invention can be achieved by the following technical solutions: A high-efficiency anaerobic wastewater flow-limiting structure includes a cylinder body and a conveying mixing component located inside the cylinder body.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Embodiment 1: Please refer to Figures 1 - 6 As shown, for the problem that in the prior art, when liquid is injected, it is difficult to ensure that the later incoming wastewater and water are fully mixed before being discharged by the method of hitting the baffle and then contacting the liquid level of the mixed liquid, the following solutions can be adopted; An efficient anaerobic wastewater flow limiting structure in this embodiment includes a cylinder body 1 for mixing wastewater and water and stably discharging the mixed liquid, and a conveyor-type mixing assembly 2 located inside the cylinder body 1. First, the sinking injection of wastewater and water is realized, and then the multi-stage high-efficiency mixing treatment of the mixed liquid is realized before being discharged. A liquid inlet pipe I 11 and a liquid inlet pipe II 12 are installed at the top of the cylinder body 1, and flow control valves are installed on both the liquid inlet pipe I 11 and the liquid inlet pipe II 12; The provided liquid inlet pipe I 11, liquid inlet pipe II 12 and the corresponding flow control valves are respectively used for injecting water and wastewater and controlling the flow rates of the two to enter, so as to achieve the flow limiting effect during discharge. A liquid outlet pipe I 13 and a control panel are installed on the outer wall of one side of the cylinder body 1. A turbidity sensor is installed on the inner side wall of the cylinder body 1 and below the liquid outlet pipe I 13. The flow control valves on the liquid inlet pipe I 11 and the liquid inlet pipe II 12 are controlled through the controller in the control panel to adjust the flow rates of water and sewage entering the cylinder body 1, and thus indirectly adjust the flow rate of the mixed liquid entering the anaerobic reactor; As water and wastewater are added, the liquid level height of the mixed liquid gradually rises, first contacts the turbidity sensor, and the turbidity sensor collects data on the turbidity of the mixed liquid and transmits the collected data obtained from the detection to the controller. The controller compares the collected data with the set data range: When the collected data is greater than or equal to the set data range, a control signal is generated and the flow control valve is controlled to reduce the flow rate of the flow control valve on the inlet pipe 11 and increase the flow rate of the flow control valve on the inlet pipe 2 12. When the collected data is less than the set data range, the flow control valve on the inlet pipe 11 increases the flow rate and the flow control valve on the inlet pipe 2 12 reduces the flow rate, so as to maintain a stable flow rate of the mixed liquid while optimizing and controlling the turbidity of the mixed liquid at all times.

[0019] The conveying mixing assembly 2 includes a rotating liquid inlet seat 21 rotatably mounted on the top of the cylinder 1, and the bottom of the rotating liquid inlet seat 21 is fixedly connected with a waste water pipe 22 and a water inlet pipe 23, the water inlet pipe 23 is located outside the waste water pipe 22, and the two are coaxially arranged, and waste water and water are introduced into the mixed liquid through the waste water pipe 22 and the water inlet pipe 23 to avoid contact with the mixed liquid, resulting in discharge without sufficient mixing, and the problem of liquid surface disturbance during the injection process causing unstable discharge flow; The two sides of the wastewater pipe 22 are connected with a disturbance frame 25 through a telescopic sleeve 24. The wastewater pipe 22 carries the telescopic sleeve 24 and the disturbance frame 25 to rotate, so as to stir and mix the bottom layer of the mixed liquid. The interior of the cylinder 1 is fixedly connected with a wave-proof orifice plate 3. With the arrangement of the wave-proof orifice plate 3, on the one hand, it is used to prevent large particles of impurities contained in the wastewater from entering the anaerobic reactor through the outlet pipe 13, thereby reducing the treatment efficiency of the anaerobic reactor for wastewater. On the other hand, the multi-stage mixing process is reduced to cause severe disturbance of the upper mixed liquid, avoiding the problem of unstable flow discharge that affects mixing, so as to ensure the efficient treatment effect of the anaerobic reactor on wastewater, and by setting up multiple wave-breaking orifice plates 3, it is used to further increase the calm state of the mixed liquid located at the outlet pipe 13, achieve stable flow discharge, and realize the effect of current limiting introduction. The water inlet pipe 23 is fixedly connected to the wave-breaking orifice plate 3 and the cylinder 1 through a connecting rod. The set connecting rod can further increase the range of stirring of the mixed liquid to enhance the stirring and mixing effect.

[0020] A liquid inlet trough 1 connected to the liquid inlet pipe 11 and the waste water pipe 22 is provided on the top of the rotating liquid inlet seat 21. The liquid inlet trough 1 is used to allow waste water to enter the waste water pipe 22 through the liquid inlet pipe 11, and a liquid inlet trough 2 is located outside the liquid inlet trough 1 and connected to the liquid inlet pipe 2 12. The liquid inlet trough 2 and the water inlet pipe 23 are connected through a connecting pipe. The liquid inlet trough 2 and the connecting pipe are used to allow water to enter the water inlet pipe 23 through the liquid inlet pipe 2 12 without interfering with the rotation of the waste water pipe 22.

[0021] On both inner walls of the wastewater pipe 22, flow restrictors one 26 are staggeredly installed to limit the downward flow rate of the wastewater in the wastewater pipe 22. On both inner walls of the water inlet pipe 23, flow restrictors two 27 are staggeredly installed to limit the downward flow rate of the water in the water inlet pipe 23. Liquid discharge holes 28 are penetrated and opened at the bottoms of the wastewater pipe 22 and the water inlet pipe 23, so that the transported wastewater and water are discharged to the bottom of the mixed liquid before contacting the mixed liquid, and are discharged through the top position in combination with the mixed liquid, extending the time of the wastewater and water in the cylinder 1 and improving the mixing quality. At the bottom of the cylinder 1, a motor for driving the wastewater pipe 22 to rotate is installed by bolts.

[0022] A guide pin 29 is fixedly installed on the telescopic sleeve rod 24. A cam groove 14 for sliding with the guide pin 29 is opened at the bottom inside the cylinder 1. A pipe body 41 for sliding with the corresponding disturbance frame 25 is fixedly installed on the annular filter screen 4. The arrangement of the pipe body 41 prevents the guide pin 29 from separating from the cam groove 14 and affects the stable reciprocating motion of the disturbance frame 25. When the wastewater and water enter the cylinder 1, the motor drives the wastewater pipe 22 to drive the water inlet pipe 23 to rotate. While feeding the liquid, it promotes the rotation of the telescopic sleeve rod 24, the disturbance frame 25, the connecting rod, the annular filter screen 4 and the pipe body 41, performs rapid mixing treatment on the mixed liquid, and through the circumferential rotation of the telescopic sleeve rod 24, combines with the cam groove 14 to guide the guide pin 29 installed on one side of the disturbance frame 25 on the telescopic sleeve rod 24, promoting the disturbance frame 25 to reciprocate synchronously in the corresponding pipe body 41, increasing the disturbance mixing of the mixed liquid for the second time, and further improving the mixing quality.

[0023] A second liquid discharge pipe 15 is installed inside the annular filter screen 4 at the bottom of the cylinder 1, and a sewage discharge pipe 16 is installed outside the annular filter screen 4. Control valves are installed on both the second liquid discharge pipe 15 and the sewage discharge pipe 16. For the discharge of the mixed liquid below the first liquid discharge pipe 13, the control valve on the second liquid discharge pipe 15 is opened for discharge. A plurality of sludge scraping plates 43 are fixedly connected to the outer bottom of the annular filter screen 4 for mixing treatment of the mixed liquid outside the annular filter screen 4.

[0024] At the bottom of the anti-wave hole plate 3, a plurality of rotating rods distributed in an annular array relative to the annular filter screen 4 are rotatably installed, and a cleaning brush 31 and a gear 32 are fixedly installed on the rotating rods. A tooth ring 44 meshing with the gear 32 is fixedly installed on the annular filter screen 4. By means of the rotation of the annular filter screen 4 carrying the tooth ring 44 and the meshing of the tooth ring 44 with a plurality of gears 32, a plurality of cleaning brushes 31 are promoted to rotate, so as to perform three-time mixing treatment on the mixed liquid and further ensure the full mixing of the mixed liquid.

[0025] Embodiment Two: Please refer to Figures 2 - 8 As shown, for the problem that it is not easy to automatically discharge impurities in the wastewater, the following solution can be adopted; In this embodiment, a guiding pin 29 is fixedly installed on the telescopic sleeve rod 24. A cam groove 14 for the guiding pin 29 to slide is formed at the bottom inside the cylinder body 1. A pipe body 41 for the corresponding disturbing frame 25 to slide is fixedly installed on the annular filter screen 4. Through the circumferential rotation of the telescopic sleeve rod 24 and the guidance of the cam groove 14 and the guiding pin 29, the disturbing frame 25 is urged to reciprocate synchronously inside the corresponding pipe body 41.

[0026] On both sides inside the disturbing frame 25, a first rotating baffle 210 is hinged. And a limiting plate in contact with the end of the first rotating baffle 210 is fixedly connected to the middle inside the disturbing frame 25. When the disturbing frame 25 moves away from the water inlet pipe 23 inside the corresponding pipe body 41, the first rotating baffle 210 is restricted from rotating under the resistance of the limiting plate, thereby pushing the mixture inside the pipe body 41 to move and injecting it outside the annular filter screen 4, and extruding the mixture outside to cause it to filter and flow back through the annular filter screen 4, realizing the isolated collection of impurities inside the mixture. A second rotating baffle 42 is hinged to the top of one side inside the pipe body 41. When the disturbing frame 25 moves towards the water inlet pipe 23 inside the corresponding pipe body 41, the second rotating baffle 42 restricts the mixture outside the annular filter screen 4 from being extracted through the pipe body 41, and causes the first rotating baffle 210 to rotate, thereby extracting the liquid containing suspended impurities inside the annular filter screen 4 until the disturbing frame 25 moves in the reverse direction and again pushes the mixture containing suspended impurities to the outside of the annular filter screen 4 for filtration treatment.

[0027] A first limiting block for restricting the deflection angle of the first rotating baffle 210 is fixedly connected to the inner side wall of the disturbing frame 25. The provided first limiting block is used to restrict the excessive rotation of the first rotating baffle 210. When the disturbing frame 25 moves in the reverse direction, with the resistance of the mixture to it, the first rotating baffle 210 quickly completes the reset rotation, realizing the isolated collection of impurities. A second limiting block is fixedly connected to the top of one side of the second rotating baffle 42. When the disturbing frame 25 moves towards the water inlet pipe 23 inside the corresponding pipe body 41, the second limiting block is used to limit the position of the second rotating baffle 42 after blocking the pipe body 41 to prevent the problem that it cannot block water due to excessive rotation.

[0028] A second liquid outlet pipe 15 is installed inside the bottom of the cylinder body 1 within the annular filter screen 4, and a sewage discharge pipe 16 is installed outside the annular filter screen 4. Control valves are installed on both the second liquid outlet pipe 15 and the sewage discharge pipe 16. For the impurities outside the annular filter screen 4, the control valve on the sewage discharge pipe 16 is opened to discharge them. A plurality of sludge scraping plates 43 are fixedly connected to the outer bottom of the annular filter screen 4. After the mixture inside the cylinder body 1 is discharged through the second liquid outlet pipe 15, with the rotation of the annular filter screen 4 carrying the sludge scraping plates 43, the impurities at the bottom of the outer side of the cylinder body 1 of the annular filter screen 4 are pushed to assist in discharging. The sludge scraping plates 43 can be of an L-shaped structure and simultaneously clean the annular side wall of the cylinder body 1.

[0029] A plurality of rotating rods that are rotationally installed at the bottom of the wave prevention orifice plate 3 and are distributed in an annular array relative to the annular filter screen 4 are provided, and a cleaning brush 31 and a gear 32 are fixedly installed on the rotating rods. A toothed ring 44 that meshes with the gear 32 is fixedly installed on the annular filter screen 4. By means of the rotation of the annular filter screen 4 carrying the toothed ring 44 and the meshing of the toothed ring 44 with a plurality of gears 32, a plurality of cleaning brushes 31 are caused to rotate, impurities on the annular filter screen 4 are cleaned, and with the assistance of the mud scraping plate 43, automatic discharge of the impurities is completed.

[0030] Embodiment 3: Please refer to Figures 1 - 8 As shown, the present invention also proposes a usage method of an efficient anaerobic wastewater flow limiting structure, including the following steps: Step 1: Inject wastewater into the first liquid inlet tank through the first liquid inlet pipe 11, and then discharge it to the bottom inside the cylinder 1 through the liquid outlet hole 28 on the wastewater pipe 22. Inject water into the second liquid inlet tank through the second liquid inlet pipe 12, and then synchronously discharge it to the bottom inside the cylinder 1 through the connecting pipe and the liquid outlet hole 28 on the water inlet pipe 23 and mix it with the wastewater to reduce the turbidity of the wastewater. As water and wastewater are added, the liquid level height of the mixed liquid gradually increases. First, it contacts the turbidity sensor installed on the inner wall of the cylinder 1, and then is discharged into the anaerobic reactor through the first liquid outlet pipe 13. Large particle impurities in the mixed liquid are blocked by the wave prevention orifice plate 3; Step 2: Control the flow control valves on the first liquid inlet pipe 11 and the second liquid inlet pipe 12 through the controller in the control panel to adjust the flow rates of water and sewage entering the cylinder 1, thereby indirectly adjusting the flow rate of the mixed liquid entering the anaerobic reactor, and collecting data on the turbidity of the mixed liquid through the turbidity sensor and transmitting it to the controller. The controller compares the collected data with the set data range and makes opening and closing adjustments to the flow control valves to maintain a stable flow rate of the discharged mixed liquid while controlling the turbidity of the mixed liquid; Step 3: While wastewater and water enter the cylinder 1, the motor drives the wastewater pipe 22 to carry the water inlet pipe 23 to rotate. While feeding liquid, the telescopic sleeve rod 24, the disturbance frame 25, the connecting rod, the annular filter screen 4 and the pipe body 41 are caused to rotate to perform rapid mixing treatment on the mixed liquid. Through the circumferential rotation of the telescopic sleeve rod 24 and the guidance of the cam groove 14 and the guide pin 29, the disturbance frame 25 is caused to reciprocate synchronously inside the corresponding pipe body 41, secondarily increasing the disturbance mixing of the mixed liquid and improving the mixing quality; Step 4: When the disturbance frame 25 moves in the corresponding pipe body 41 towards the water inlet pipe 23, the rotating baffle plate II 42 blocks the pipe body 41 under the restriction of the limiting block II, and under the obstruction of the liquid, the rotating baffle plate I 210 deflects to prevent the liquid outside the annular filter screen 4 from being extracted through the pipe body 41, so as to extract the liquid containing suspended impurities inside the annular filter screen 4. When the disturbance frame 25 moves away from the water inlet pipe 23, the rotating baffle plate I 210 combines with the limiting block I to reset and deflect, promoting the rotation of the rotating baffle plate II 42 by the impurities carried by the liquid in the pipe body 41, and pushing it to the outside of the annular filter screen 4. Then, the liquid is filtered and refluxed through the annular filter screen 4 to complete the isolated collection of impurities inside the mixed liquid; Step 5: For the discharge of the mixed liquid below the first liquid outlet pipe 13, it is discharged by opening the control valve on the second liquid outlet pipe 15. For the impurities outside the annular filter screen 4, they are discharged by opening the control valve on the sewage discharge pipe 16. With the rotation of the annular filter screen 4 carrying the toothed ring 44 and the meshing of the toothed ring 44 with multiple gears 32, multiple cleaning brush rollers 31 are promoted to rotate to clean the impurities on the annular filter screen 4, and with the assistance of the mud scraping plate 43, the automatic discharge of impurities is completed. In addition, during the mixing process, with the rotation of the cleaning brush rollers 31, the mixed liquid is subjected to three times of mixing treatment to further ensure the full mixing of the mixed liquid.

[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
