[0002] Sewage treatment is the process of purifying sewage so that it meets the water quality requirements for discharge into a water body or reuse. Disinfection equipment is used to treat and disinfect sewage. Sewage treatment generally includes filtering solid impurities. Sewage also contains a large amount of organic matter. Therefore, disinfection equipment is needed when treating sewage.

[0004] However, in the actual use of the above-mentioned equipment, the organic matter contained in the sewage is generally treated by microbial filtration and aeration, which eventually causes the organic matter in the sewage to precipitate and eventually be discharged. However, since the microbial treatment of organic matter in sewage has certain requirements for the pH value of the sewage, and the activity of the microorganisms themselves will gradually decrease, the continuous addition of materials not only wastes raw materials, but also the dispersion area of ​​these additives in the sewage treatment equipment is limited, thereby having limited effect on improving the efficiency of sewage treatment.

[0016] Compared with the prior art, the present invention provides a disinfection device for sewage treatment, which has the following beneficial effects: 1. The disinfection device for sewage treatment is provided with an injection assembly. Through the continuous rotation of the aeration plate, the inner gear ring can drive the aeration plate and the injection barrel to have a speed difference, so that the piston rod is affected by the wave groove and the convex ball to perform continuous reciprocating piston motion inside the injection barrel, and cooperate with the piston plate to pressurize the space inside the injection barrel, so that the pH value regulator in the injection barrel is ejected into the treatment tank through the one-way valve. In this process, as the injection barrel rotates, the diffusion range of the pH value regulator and the microbial activator is expanded, thereby maintaining the pH value of the sewage and the activity of the microorganisms in the treatment tank, and ensuring the purification efficiency of the equipment on the organic matter contained in the sewage.

[0017] 2. The disinfection device for sewage treatment is provided with a diffusion component. During the continuous rotation of the aeration disc, it is affected by the high-speed airflow generated in the aeration head, and under the influence of the elastic force of the scroll spring, the rotating ring is prompted to make a small reciprocating rotation on the outside of the aeration head, and at the same time drives the blades to rotate back and forth, so as to increase the flow rate of sewage around the aeration head, so as to quickly diffuse the bubbles generated by the aeration head in the treatment tank, thereby effectively increasing the dissolved oxygen content in the sewage in the treatment tank, thereby improving the efficiency of microbial degradation of organic matter in the sewage.

[0018] 3. The disinfection device for sewage treatment is provided with an anti-blocking component, which cooperates with the relative rotation of the injection barrel and the aeration disk, so that the turntable will drive the arc plate to intermittently squeeze the convex rod inside the aeration disk, so as to prompt the convex rod to push the rotating ring upward, thereby changing the relative position of the rotating ring and the aeration head. Due to the rotation of the rotating ring on the outer surface of the aeration head, the cleaning ring will drive the cleaning plate to continuously sweep the outer surface of the aeration head under the elastic force of the guide spring, so as to prevent the organic degradation residues from adhering to the outer surface of the aeration head, thereby affecting the subsequent sewage treatment aeration work.

[0019] 4. The disinfection device for sewage treatment is provided with a rolling assembly. When the high-speed airflow is output outward from the aeration plate, the high-speed airflow enters the air outlet pipe through the air guide tube, and as the air pressure in the air outlet pipe increases, the arc-shaped sheet is pushed outward, and the high-speed airflow is released outward through the square opening to form bubbles on the outside of the drum, thereby increasing the dissolved oxygen content in the sewage at the bottom of the treatment tank. At the same time, through the setting of the pointed cone, the drum will also squeeze the precipitated sludge on the inner wall of the bottom of the treatment tank during rotation, so that the residual sewage inside can continue to react with the microorganisms, ensuring the sewage treatment effect of the device on the bottom position with low dissolved oxygen.

A wave groove 716 is provided on the arc-shaped inner surface of the injection barrel 710, and the convex ball 715 is arranged inside the wave groove 716.

[0024] Please refer to the instruction manual for details. Figure 1-Figure 2In an embodiment of the present invention, the outlet valve 3 and the inlet valve 2 are respectively arranged on the left and right sides of the treatment tank 1. Specifically, the inlet valve 2 is connected to an external water supply pipe, and the outlet valve 3 is connected to other sewage treatment equipment, so that after the organic matter in the sewage is precipitated and removed in the treatment tank 1, it undergoes other sewage treatment steps and finally the sewage is purified to a usable degree to ensure the recycling of water resources. At the same time, an isolation chamber is arranged at the bottom of the treatment tank 1, and air holes are opened on the side of the isolation chamber, so that the aeration pump 4 and the drive motor 71 in normal operation will not affect the normal working efficiency of the above equipment due to the high temperature in the closed environment during operation. At the same time, a discharge port is arranged on the side of the treatment tank 1 to facilitate the timely extraction of the sludge precipitated in the treatment tank 1.

[0025] In addition, please refer to the instructions attached Figure 3-Figure 6 The driven gear 73 meshes with the driving gear 72 to realize transmission, so that when the driving motor 71 is started, the driving gear 72 rotates to make the driven gear 73 drive the aeration plate 5 to rotate. At the same time, a small cylinder is provided at the bottom of the chassis 74, so that there is a large gap between the chassis 74 and the top of the bottom air intake pipe of the aeration plate 5, so that when the bottom air intake pipe of the aeration plate 5 is connected to the output end of the aeration pump 4, the high-speed airflow formed by the compressed air transmitted in the aeration pump 4 can enter the internal cavity of the aeration plate 5 through the bottom air intake pipe of the aeration plate 5, and finally to the treatment tank 1 through the aeration head 6. The oxygen content in the wastewater in the treatment tank 1 is output to achieve the effect of aeration, thereby increasing the oxygen content in the wastewater in the treatment tank 1, and then increasing the decomposition efficiency of the microorganisms in the treatment tank 1 to the organic matter. Furthermore, a square groove adapted to the square rod 75 is opened on the bottom inner wall of the piston rod 76, and the square rod 75 is arranged inside the square groove. Specifically, the two ends of the return spring 77 are respectively connected to the top surface of the square rod 75 and the top inner wall of the square groove, so that the piston rod 76 can only move in the vertical direction, and under the elastic force of the return spring 77, the piston rod 76 always has a tendency to move downward and fit against the upper surface of the chassis 74.

[0026] At the same time, the inner gear ring 713 is arranged in a T shape, and the number of pinion gears 79 is arranged in multiple groups, and the multiple groups of pinion gears 79 are evenly distributed on the top lower surface of the inner gear ring 713 in a circular array. In addition, the inner and outer sides of the pinion gear 79 are respectively meshed with the gear ring 78 and the inner gear ring 713 to realize transmission. Further, when the aeration disk 5 rotates, the gear ring 78 will rotate synchronously with the aeration disk 5 in the same direction, and with the cooperation of the pinion gear 79, the gear ring 78, the pinion gear 79 and the inner gear ring 713 are arranged in a planetary gear shape, and the inner gear ring 713 will rotate at a lower speed than the rotation speed of the gear ring 78, that is, there is a speed difference between the aeration disk 5 and the inner gear ring 713, so that the aeration disk 5 5 has a rotation speed difference with the injection barrel 710. In addition, the pH value regulator and the microbial active agent are pre-added into the injection barrel 710 during the sewage treatment process. At the same time, the injection barrel 710 is rotatably connected to the top inner wall of the treatment tank 1, and the top of the injection barrel 710 exceeds the top of the treatment tank 1, so that the staff can add materials in time when treating the sewage to ensure the continuity of the sewage treatment process. At the same time, a one-way air inlet valve is provided at the center of the sealing cover 711 to replenish the air in the external environment in time when the piston plate 714 stretches the internal cavity of the injection barrel 710, so as to facilitate the pH value regulator and the microbial active agent in the injection barrel 710 to be injected into the interior of the treatment tank 1.

[0027] Specifically, the outer diameter of the piston rod 76 is adapted to the internal cavity of the injection barrel 710, and the number of the one-way valves 712 is set in a plurality of groups, and the plurality of one-way valves 712 are evenly distributed on the arc-shaped outer wall of the injection barrel 710 in a spiral array. During the relative rotation between the aeration plate 5 and the injection barrel 710, the piston rod 76 is affected by the wave groove 716 and the convex ball 715, so that the piston rod 76 performs a continuous reciprocating piston motion inside the injection barrel 710, and cooperates with the piston plate 714 to pressurize the space inside the injection barrel 710, thereby causing the pH value in the injection barrel 710 to increase. The regulator is sprayed into the treatment tank 1 through the one-way valve 712. During this process, as the injection barrel 710 rotates, the diffusion range of the pH regulator and the microbial active agent is expanded. In the reset stage of the piston movement, the piston plate 714 moves downward relative to the injection barrel 710. At this time, the one-way air inlet valve provided on the sealing cover 711 is used to replenish air inside the injection barrel 710, thereby facilitating the next spraying of the pH regulator and the microbial active agent, thereby maintaining the sewage pH value and the activity of the microorganisms in the treatment tank 1, and ensuring the purification efficiency of the equipment for organic matter contained in the sewage.

[0028] Please refer to the instruction manual Figure 4 and Figure 7The surface of the aeration disk 5 is provided with a diffusion component 8 which can diffuse and disperse the bubbles generated by the aeration head 6. The diffusion component 8 includes an air outlet 81, and the air outlet 81 is opened on the arc-shaped outer surface of the aeration head 6. A rotating ring 82 is rotatably installed on the arc-shaped outer surface of the aeration head 6. An annular cavity is opened at the axis center of the rotating ring 82, and a volute spring 83 is arranged in the annular cavity. The two ends of the volute spring 83 are respectively fixedly connected to the arc-shaped outer wall of the aeration head 6 and the side inner wall of the annular cavity. A baffle 84 is fixedly installed on the arc-shaped inner surface of the rotating ring 82, and a blade 85 is fixedly installed on the arc-shaped outer wall of the rotating ring 82.

[0029] Specifically, there are multiple groups of diffusion components 8, and each group of diffusion components 8 is provided with two in a linear array, and the two diffusion components 8 are arranged in a linear array on the top arc surface of the aeration disk 5, and multiple groups of diffusion components 8 are arranged in a circular array to increase the amount of bubbles generated by the aeration disk 5 when aerating the treatment tank 1, so that the dissolved oxygen content in the sewage to be treated is increased, thereby improving the degradation efficiency of organic matter by microorganisms in the treatment tank 1. Furthermore, the aeration head 6 includes a large diameter end and a small diameter end, and the small diameter end is arranged on the side close to the aeration disk 5. At the same time, the rotating ring 82 and the scroll spring 83 are both arranged on the outside of the small diameter end of the aeration head 6. At the same time, the air outlet 81 is arranged in a relatively inclined state with respect to the diameter direction of the large diameter end.

[0030] In addition, the high-speed airflow ejected from the aeration head 6 will be ejected outward at the periphery of the aeration head 6 at an angle to the diameter direction of the aeration head 6 itself, and the high-speed airflow has a certain initial velocity in the process of forming bubbles on the outside of the aeration head 6, so that after these bubbles with a certain velocity come into contact with the baffle 84, a driving force is generated on the baffle 84, thereby prompting the baffle 84 to drive the rotating ring 82 to rotate on the outside of the small-diameter end of the aeration head 6. At this time, due to the elastic force restriction of the volute spring 83, the rotating ring 82 will have the reverse rotation and return when the thrust of the bubbles is slightly weak. The movement trend of the aeration disc 5 eventually makes the aeration disc 5 be affected by the high-speed airflow generated in the aeration head 6 during its continuous rotation, and under the influence of the elastic force of the spiral spring 83, the rotating ring 82 is prompted to rotate back and forth slightly on the outside of the aeration head 6, and at the same time drives the blades 85 to rotate back and forth, so as to increase the flow rate of sewage around the aeration head 6, so as to quickly diffuse the bubbles generated by the aeration head 6 in the treatment tank 1, thereby effectively increasing the dissolved oxygen content in the sewage in the treatment tank 1, thereby improving the efficiency of microorganisms in degrading organic matter in the sewage.

[0031] Please refer to the instruction manual Figure 7-Figure 9In the present invention, an anti-blocking component 9 for intermittently cleaning the surface of the aeration head 6 is provided on the outer side of the aeration disk 5. The anti-blocking component 9 includes a convex rod 91, which penetrates and is slidably installed on the inner wall of the aeration disk 5. A small spring 92 is sleeved on the arc-shaped outer wall of the convex rod 91 close to the center of the aeration disk 5. The end of the convex rod 91 away from the small spring 92 is movably connected to the lower surface of the rotating ring 82. A cleaning ring 93 is rotatably installed on the upper surface of the bottom of the rotating ring 82. A cleaning plate 94 is fixedly installed on the upper surface of the cleaning ring 93. A convex block 95 is fixedly installed on the arc-shaped inner surface of the cleaning ring 93. A guide spring 96 is fixedly connected between the convex block 95 and the inner wall of the bottom of the rotating ring 82. A rotating disk 97 is rotatably installed on the inner wall of the aeration disk 5, and an arc plate 98 is fixedly installed on the upper surface of the rotating disk 97.

[0032] In the embodiment of the present invention, a through hole with a diameter matching that of the convex rod 91 is provided on the top arc-shaped inner wall of the aeration plate 5, and a hole with a diameter larger than the outer diameter of the small spring 92 is provided at one end of the through hole near the center of the aeration plate 5 to facilitate the installation of the small spring 92. At the same time, a circular plate matching the inner diameter of the above-mentioned hole is provided on the arc-shaped outer wall at one end of the convex rod 91 near the center of the aeration plate 5, and the two ends of the small spring 92 are respectively fixedly connected to the side wall of the circular plate and the top inner wall of the hole, so that the convex rod 91 can perform linear motion in the through hole and reset. Furthermore, an arc block is provided at the top of the convex rod 91, and the rotating ring 82 An annular arc groove adapted to the above-mentioned arc block is provided on the lower surface, so that the top end of the convex rod 91 can always be connected to the rotating ring 82, and will not affect the rotation of the rotating ring 82 itself with the aeration head 6 as the rotation center. At the same time, the outer surface of the cleaning plate 94 close to the aeration head 6 is arranged to be an arc adapted to the aeration head 6, and the cleaning plate 94 is provided with bristles on the side close to the aeration head 6, so that the cleaning plate 94 can brush and clean the arc-shaped outer surface of the aeration head 6 during the rotation of the cleaning ring 93, so as to avoid organic matter precipitation and residue on the surface of the aeration head 6, thereby affecting the subsequent sewage treatment work.

[0033] At the same time, an annular groove matched with the cleaning ring 93 is provided on the bottom upper surface of the rotating ring 82, so that the cleaning ring 93 can rotate on the bottom upper surface of the rotating ring 82. In addition, a plurality of fan-shaped cavities are provided on the inner wall of the rotating ring 82, so that the interior of the rotating ring 82 is not a closed space, and thus a large amount of organic matter will not be precipitated and remain. The two ends of the guide spring 96 are respectively fixedly connected to the side walls of the fan-shaped cavity and the side walls of the protrusion 95. At the same time, an arc-shaped telescopic hose is provided at the center of the guide spring 96, so that the guide spring 96 can only move along the outer surface of the arc-shaped telescopic hose, so as to limit the rotation angle of the cleaning ring 93 on the rotating ring 82. Specifically, the axis of the turntable 97 is fixedly connected to the outer wall of the bottom end of the injection barrel 710, so that as the injection barrel 710 and the aeration plate 5 rotate relative to each other, the turntable 97 will drive the arc plate 98 to intermittently squeeze the protruding rod 91 inside the aeration plate 5, so as to prompt the protruding rod 91 to push the rotating ring 82 upward, thereby changing the relative position of the rotating ring 82 and the aeration head 6. Due to the rotation of the rotating ring 82 on the outer surface of the aeration head 6, the cleaning ring 93 will drive the cleaning plate 94 to continuously sweep the outer surface of the aeration head 6 under the elastic force of the guide spring 96, so as to prevent the organic degradation residues from adhering to the outer surface of the aeration head 6, thereby affecting the subsequent sewage treatment aeration work.

[0034] Please refer to the instruction manual Figure 10-11 In an embodiment of the present invention, a rolling assembly 10 is provided on the arc-shaped outer wall of the aeration plate 5, which can squeeze the precipitated organic matter and close to the aeration to promote the reaction. The rolling assembly 10 includes an air guide cylinder 101, which is fixedly installed on the arc-shaped outer wall of the aeration plate 5. A roller 102 is sleeved on the outer surface of the air guide cylinder 101, and an air outlet pipe 103 is slidably installed through the inner wall of the roller 102. An arc-shaped sheet 104 is fixedly installed on the end of the air outlet pipe 103 away from the air guide cylinder 101, and a pointed cone 105 is fixedly installed on the lower surface of the arc-shaped sheet 104. A square opening 106 is opened on the arc-shaped outer wall of the end of the air outlet pipe 103 close to the arc-shaped sheet 104, and a disc 107 is penetrated and fixedly installed on the air outlet pipe 103. A contraction spring 108 is fixedly connected to the end of the disc 107 away from the air guide cylinder 101.

[0035] It is worth noting that there are three groups of rolling assemblies 10, and the three groups of rolling assemblies 10 are evenly distributed on the arc-shaped outer wall of the aeration plate 5 in a circular array, and the roller 102 is rotatably connected to the air guide cylinder 101. When blocked by the sediment at the bottom of the treatment tank 1, the sediment will cause the roller 102 to rotate on the outer surface of the air guide cylinder 101. At the same time, there are multiple groups of square openings 106, and the multiple groups of square openings 106 are evenly distributed on the bottom arc-shaped outer surface of the outlet pipe 103 in a circular array. Furthermore, a through hole compatible with the outlet pipe 103 is opened on the inner wall of the roller 102, and a through hole compatible with the disc 107 is opened at the center of the through hole. The adapted cylindrical hole, specifically, the disc 107 and the contraction spring 108 are both arranged inside the cylindrical hole. Under the elastic force of the contraction spring 108, the air outlet pipe 103 and the arc-shaped sheet 104 maintain a tendency to move outward, and then when the high-speed airflow is output outward from the aeration plate 5, the high-speed airflow enters the air outlet pipe 103 through the air guide cylinder 101, and as the air pressure in the air outlet pipe 103 increases, the arc-shaped sheet 104 is pushed outward, and at the same time, the high-speed airflow is released outward through the square opening 106 to form bubbles on the outside of the drum 102, thereby increasing the dissolved oxygen content in the sewage at the bottom of the treatment tank 1, thereby improving the degradation efficiency of organic matter in the sewage by microorganisms at this position.

[0036] At the same time, the arc-shaped piece 104 at the bottom of the drum 102 will be squeezed and fit with the outer surface of the drum 102, and finally the square opening 106 will shrink into the through hole, and the arc-shaped piece 104 away from the bottom of the drum 102 will move to the side away from the drum 102 due to the influence of the high-speed airflow and the contraction spring 108, thereby exposing the square opening 106, thereby spraying bubbles around the drum 102. At the same time, through the setting of the pointed cone 105, the drum 102 will also squeeze the precipitated sludge on the inner wall of the bottom of the treatment tank 1 during the rotation process, so that the residual sewage inside it can continue to react with the microorganisms, ensuring the device's treatment effect on sewage at the bottom with low dissolved oxygen.

[0037] In the present invention, when in use, external sewage is input into the interior of the treatment tank 1 through the water inlet valve 2. At this time, the driving motor 71 is started, and the rotation of the active gear 72 is coordinated so that the driven gear 73 drives the aeration plate 5 to rotate, and the aeration pump 4 is started at the same time, so that the high-speed airflow formed by the compressed air transmitted in the aeration pump 4 can enter the internal cavity of the aeration plate 5 through the air inlet pipe at the bottom of the aeration plate 5, and finally output to the wastewater in the treatment tank 1 through the aeration head 6. The aeration plate 5 is continuously rotated, so that the bubbles discharged from the aeration head 6 can diffuse in the sewage in the treatment tank 1, thereby increasing the dissolved oxygen content in the sewage, and then improving the degradation efficiency of the organic matter in the sewage by the microorganisms in the treatment tank 1.

[0038] At the same time, through the continuous rotation of the aeration plate 5, in cooperation with the pinion 79, the inner ring gear 713 will rotate at a lower speed than the rotation speed of the ring gear 78, so that there is a speed difference between the aeration plate 5 and the injection barrel 710. Affected by the wave groove 716 and the convex ball 715, the piston rod 76 is caused to perform continuous reciprocating piston motion inside the injection barrel 710, and in cooperation with the piston plate 714, the space inside the injection barrel 710 is pressurized, so that the pH adjuster in the injection barrel 710 is ejected into the treatment tank 1 through the one-way valve 712. In this process, as the injection barrel 710 rotates, the diffusion range of the pH adjuster and the microbial active agent is expanded, thereby facilitating the next ejection of the pH adjuster and the microbial active agent, thereby maintaining the pH value of the sewage and the activity of the microorganisms in the treatment tank 1, and ensuring the equipment's purification efficiency of organic matter contained in the sewage.

[0039] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
