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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figures 1-6 As shown, the existing technology, which uses liquid injection to impact the baffle plate and then mix with the liquid surface, makes it difficult to ensure that the wastewater and water are fully mixed before discharge. The following solution can be used to solve this problem.

[0034] This embodiment of a high-efficiency anaerobic wastewater flow-limiting structure includes a cylinder 1 for mixing wastewater and water and for stably discharging the mixture, and a conveying mixing component 2 located inside the cylinder 1, which first realizes the sinking injection of wastewater and water, and then realizes multi-stage high-efficiency mixing treatment of the mixture before discharge. The top of the cylinder 1 is equipped with an inlet pipe 11 and an inlet pipe 12, and both the inlet pipe 11 and the inlet pipe 12 are equipped with flow control valves.

[0035] The inlet pipe 11 and inlet pipe 2 12, along with their corresponding flow control valves, are used to inject water and wastewater, respectively, and control their flow rates to achieve flow restriction during discharge. An outlet pipe 13 and a control panel are installed on one outer wall of the cylinder 1. A turbidity sensor is installed on the inner wall of the cylinder 1, below the outlet pipe 13. The flow control valves on the inlet pipe 11 and inlet pipe 2 12 are controlled by the controller in the control panel to regulate the flow rate of water and wastewater entering the cylinder 1, thereby indirectly regulating the flow rate of the mixed liquor entering the anaerobic reactor.

[0036] With the addition of water and wastewater, the liquid level of the mixed liquid gradually rises, first contacts the turbidity sensor, and collects data on the turbidity of the mixed liquid through the turbidity sensor, and transmits the collected data to the controller. The controller compares the collected data with the set data range:

[0037] When the collected data is greater than or equal to the set data range, a control signal is generated to control the flow control valve, so that the flow control valve on the liquid inlet pipe 11 reduces the flow, and the flow control valve on the liquid inlet pipe 12 increases the flow. When the collected data is less than the set data range, the flow control valve on the liquid inlet pipe 11 increases the flow, and the flow control valve on the liquid inlet pipe 12 reduces the flow, so as to maintain the stable flow of the mixed liquid while optimizing the turbidity of the mixed liquid at all times.

[0038] The conveying type mixing assembly 2 includes a rotating liquid inlet seat 21 rotatably installed at the top of the cylinder body 1, and the bottom of the rotating liquid inlet seat 21 is fixedly connected with a wastewater pipe 22 and a water inlet pipe 23. The water inlet pipe 23 is located outside the wastewater pipe 22 and is coaxially arranged with the wastewater pipe 22. The wastewater and water are introduced into the mixed liquid through the wastewater pipe 22 and the water inlet pipe 23 to avoid the problem of not being fully mixed and being discharged due to contact with the mixed liquid, as well as the problem of unstable discharge flow caused by liquid surface disturbance during the liquid injection process;

[0039] The wastewater pipe 22 is connected with a disturbance frame 25 on both sides through a telescopic sleeve rod 24, which rotates with the wastewater pipe 22 to carry the telescopic sleeve rod 24 and the disturbance frame 25, and stirs and mixes the bottom layer of the mixed liquid. The inside of the cylinder body 1 is fixedly connected with a wave prevention hole plate 3. With the arrangement of the wave prevention hole plate 3, on the one hand, it is used to avoid large particles in the wastewater entering the anaerobic reactor through the liquid outlet pipe 13, thereby reducing the treatment efficiency of the anaerobic reactor on the wastewater;

[0040] On the other hand, it reduces the multi-stage mixing process, causing the violent disturbance of the upper layer of the mixed liquid, avoids the problem of unstable flow discharge while mixing, to ensure the efficient treatment effect of the anaerobic reactor on the wastewater, and by arranging multiple wave prevention hole plates 3, it is used to further increase the calm state of the mixed liquid at the liquid outlet pipe 13, to achieve the effect of stable flow discharge and realize the effect of flow limiting introduction. The water inlet pipe 23 is fixedly connected with an annular filter screen 4 which rotates with the wave prevention hole plate 3 and the cylinder body 1 through a connecting rod. The connecting rod can further increase the stirring range of the mixed liquid to improve the stirring and mixing effect.

[0041] The top of the rotating liquid inlet base 21 is provided with a liquid inlet groove I in communication with the liquid inlet pipe I 11 and the wastewater pipe 22, which is used for the wastewater to enter the inside of the wastewater pipe 22 through the liquid inlet pipe I 11, and a liquid inlet groove II in communication with the liquid inlet pipe II 12 outside the liquid inlet groove I, which is in communication with the water inlet pipe 23 through a connecting pipe, and the liquid inlet groove II and the connecting pipe are used for the water to enter the inside of the water inlet pipe 23 through the liquid inlet pipe II 12 without interfering with the rotation of the wastewater pipe 22.

[0042] The inner walls of the two sides of the wastewater pipe 22 are alternately provided with flow limiting plates I 26 for limiting the downward flow rate of the wastewater in the wastewater pipe 22, and the inner walls of the two sides of the water inlet pipe 23 are alternately provided with flow limiting plates II 27 for limiting the downward flow rate of the water in the water inlet pipe 23, and the bottoms of the wastewater pipe 22 and the water inlet pipe 23 are both provided with liquid outlet holes 28, so that the transported wastewater and water are discharged into the bottom of the mixed liquid before contacting the mixed liquid, and are discharged through the top position in combination with the mixed liquid, thereby prolonging the time of the wastewater and water in the barrel 1 and improving the mixing quality, and the bottom of the barrel 1 is provided with a motor for driving the wastewater pipe 22 to rotate through bolts.

[0043] The telescopic sleeve rod 24 is fixedly provided with a guide pin 29, the bottom of the barrel 1 is provided with a cam groove 14 in sliding communication with the guide pin 29, and the annular filter screen 4 is fixedly provided with a pipe body 41 in sliding communication with the corresponding disturbance frame 25, and the pipe body 41 is arranged to avoid the separation of the guide pin 29 and the cam groove 14 and to avoid affecting the stable reciprocating motion of the disturbance frame 25.

[0044] When the wastewater and water enter the barrel 1, the motor drives the wastewater pipe 22 to rotate with the water inlet pipe 23, and at the same time, the telescopic sleeve rod 24, the disturbance frame 25, the connecting rod, the annular filter screen 4 and the pipe body 41 are rotated to rapidly mix the mixed liquid, and through the circumferential rotation of the telescopic sleeve rod 24, the guide pin 29 on one side of the telescopic sleeve rod 24 is guided by the cam groove 14, so that the disturbance frame 25 is reciprocated in the corresponding pipe body 41 at the same time, thereby increasing the disturbance mixing of the mixed liquid and improving the mixing quality.

[0045] The bottom of the barrel 1 is provided with a liquid outlet pipe II 15 inside the annular filter screen 4 and a sewage discharge pipe 16 outside the annular filter screen 4, and the liquid outlet pipe II 15 and the sewage discharge pipe 16 are both provided with control valves, and the mixed liquid below the liquid outlet pipe I 13 is discharged by opening the control valve of the liquid outlet pipe II 15, and the bottom of the outside of the annular filter screen 4 is fixedly connected with a plurality of mud scraping plates 43 for mixing the mixed liquid outside the annular filter screen 4.

[0046] The bottom of the anti-wave hole plate 3 is rotatably provided with a plurality of rotating rods arranged in an annular array relative to the annular filter screen 4, and the rotating rods are fixedly provided with cleaning roller brushes 31 and gears 32. The annular filter screen 4 is fixedly provided with a gear ring 44 engaged with the gears 32. The rotation of the annular filter screen 4 carrying the gear ring 44 and the engagement of the gear ring 44 with the plurality of gears 32 promote the rotation of the plurality of cleaning roller brushes 31, so that the mixed liquid can be treated for three times, further ensuring the sufficient mixing of the mixed liquid.

[0047] Embodiment two: please refer to Figures 2-8 As shown, the problem that impurities in wastewater are not easy to be automatically discharged can be solved by the following scheme.

[0048] The telescopic sleeve rod 24 in the embodiment is fixedly provided with a guide pin 29, and the bottom of the cylinder 1 is provided with a cam groove 14 in sliding connection with the guide pin 29. The annular filter screen 4 is fixedly provided with a pipe body 41 in sliding connection with the corresponding disturbance frame 25. Through the circumferential rotation of the telescopic sleeve rod 24, in combination with the guidance of the cam groove 14 and the guide pin 29, the disturbance frame 25 is promoted to reciprocate in the corresponding pipe body 41.

[0049] Both sides of the disturbance frame 25 are hingedly provided with rotating baffles one 210, and the middle of the disturbance frame 25 is fixedly connected with a limiting plate in contact with the end of the rotating baffle one 210. When the disturbance frame 25 moves in the corresponding pipe body 41 away from the water inlet pipe 23, the rotating baffle one 210 is limited from rotating under the resistance of the limiting plate, thereby pushing the mixed liquid in the pipe body 41 to inject outside the annular filter screen 4 and extruding the mixed liquid outside to filter back through the annular filter screen 4, realizing the isolation collection of impurities in the mixed liquid.

[0050] One side of the top of the pipe body 41 is hingedly provided with a rotating baffle two 42. When the disturbance frame 25 moves in the corresponding pipe body 41 close to the water inlet pipe 23, the rotating baffle two 42 limits the mixed liquid outside the annular filter screen 4 from being extracted through the pipe body 41, and promotes the rotating baffle one 210 to rotate, so as to extract the liquid containing suspended impurities inside the annular filter screen 4, until the disturbance frame 25 moves reversely, and the mixed liquid containing suspended impurities is pushed to the outside of the annular filter screen 4 again for filtering treatment.

[0051] The inner side wall of the disturbance frame 25 is fixedly connected with a limiting block one for limiting the deflection angle of the rotating baffle one 210, and the limiting block one is arranged to limit the excessive rotation of the rotating baffle one 210, so that the disturbance frame 25 can quickly complete the reset rotation of the rotating baffle one 210 by the resistance of the mixed liquid when the disturbance frame 25 moves reversely, and the impurity isolation type collection is realized. The side top of the rotating baffle two 42 is fixedly connected with a limiting block two, and when the disturbance frame 25 moves in the pipe body 41 towards the water inlet pipe 23, the limiting block two is used to limit the position of the pipe body 41 after being blocked by the rotating baffle two 42, so as to prevent the problem of excessive rotation and unable to realize water blocking.

[0052] The bottom of the cylinder body 1 is provided with a liquid outlet pipe two 15 inside the annular filter screen 4, and a sewage pipe 16 outside the annular filter screen 4, and control valves are arranged on the liquid outlet pipe two 15 and the sewage pipe 16. The impurities outside the annular filter screen 4 are discharged by opening the control valve on the sewage pipe 16.

[0053] The bottom of the outside of the annular filter screen 4 is fixedly connected with a plurality of mud scraping plates 43. After the mixed liquid in the cylinder body 1 is discharged through the liquid outlet pipe two 15, the rotation of the annular filter screen 4 carrying the mud scraping plates 43 pushes the impurities at the bottom of the cylinder body 1 outside the annular filter screen 4 to assist in discharging. The mud scraping plates 43 can be L-shaped structures, which can simultaneously clean the annular side wall of the cylinder body 1.

[0054] The bottom of the anti-wave hole plate 3 is rotatably provided with a plurality of rotating rods arranged in an annular array relative to the annular filter screen 4, and the rotating rods are fixedly provided with cleaning roller brushes 31 and gears 32. The annular filter screen 4 is fixedly provided with a gear ring 44 engaged with the gears 32. The rotation of the annular filter screen 4 carrying the gear ring 44 and the engagement of the gear ring 44 with the plurality of gears 32 cause the plurality of cleaning roller brushes 31 to rotate, clean the impurities on the annular filter screen 4, and automatically discharge the impurities with the assistance of the mud scraping plates 43.

With the addition of water and wastewater, the liquid level of the mixed liquid gradually rises, first contacts the turbidity sensor installed on the inner wall of the cylinder body 1, and then is discharged to the anaerobic reactor through the liquid outlet pipe one 13. The large-particle impurities in the mixed liquid are blocked by the anti-wave hole plate 3.

[0057] Step two: the flow control valve on the liquid inlet pipe one 11 and the liquid inlet pipe two 12 is controlled by the controller in the control panel to adjust the flow of water and sewage into the cylinder 1, thereby indirectly adjusting the flow of mixed liquor into the anaerobic reactor, and the turbidity of the mixed liquor is collected by the turbidity sensor and transmitted to the controller, and the controller compares the collected data with the set data range to adjust the opening and closing of the flow control valve, so as to maintain the stable flow of mixed liquor and control the turbidity of the mixed liquor;

[0059] Step four: when the disturbance frame 25 moves in the corresponding pipe body 41 towards the water inlet pipe 23, the rotating baffle two 42 is blocked in the pipe body 41 under the limitation of the limiting block two, and the rotating baffle one 210 is deflected under the resistance of the liquid, so as to avoid extracting the liquid outside the annular filter screen 4 through the pipe body 41, and 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 one 210 resets the deflection combined with the limiting block one, to push the rotating baffle two 42 in the pipe body 41, and to push it to the outside of the annular filter screen 4, and then the liquid is filtered back through the annular filter screen 4, to complete the isolation collection of the impurities in the mixed liquid;

[0060] Step five: for the discharge of the mixed liquid below the liquid outlet pipe one 13, the control valve on the liquid outlet pipe two 15 is opened to discharge, and the impurities outside the annular filter screen 4 are discharged by opening the control valve on the sewage pipe 16, and the rotation of the annular filter screen 4 carrying the gear ring 44 and the meshing of the gear ring 44 and the plurality of gear wheels 32 drive the plurality of cleaning rollers 31 to rotate, to clean the impurities on the annular filter screen 4, and the automatic discharge of the impurities is completed with the aid of the mud scraper 43, in addition, during the mixing process, the mixed liquid is mixed three times by the rotation of the cleaning roller 31, to further ensure the sufficient mixing of the mixed liquid.
