Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a kitchen waste sewage MBR membrane bioprocessor. Background Art

[0002] MBR membrane is a membrane separation technology used in membrane bioreactor (MBR) to treat wastewater and sewage. MBR membranes are usually made of polymer or ceramic materials and have a microporous structure, which can effectively filter out pollutants such as solid particles, bacteria and viruses in the water while retaining beneficial microorganisms. MBR membrane technology has the advantages of high efficiency, energy saving and small footprint, and is widely used in the field of wastewater treatment.

[0003] For example, the Chinese utility model patent with patent publication number CN213865824U, although this patent allows sewage to enter the interior of the filter device through the water inlet pipe during use, and is filtered from the inside to the outside under the push of pressure, and is effectively filtered through the MBR membrane inside the filter device, and finally is coarsely filtered and discharged through the filter plate inside the filter box, but it accumulates impurities and garbage inside the sewage pipe during filtration. At this time, it is necessary to use a sealing cover to close the sewage pipe to prevent the propeller from discharging sewage and garbage together through the sewage pipe. However, due to the limited volume of the sewage pipe, when the garbage inside the sewage pipe is full, it is necessary to stop the machine to collect the garbage in the sewage pipe, but it is impossible to treat the sewage continuously, which reduces the practicality of the processor. In view of this, we have proposed a kitchen waste sewage MBR membrane biological processor. Utility Model Content

[0006] Preferably, the support assembly includes a support sleeve, which is sleeved on the outer surface of the second motor, and the outer surface of the first motor is also sleeved with a support sleeve, and a support plate is fixedly connected between the two support sleeves.

[0007] Preferably, a surface of the sealing plate on one side away from the rotating shaft is provided with a wear-resistant coating, and an inner wall of the sealing cavity is provided with a second wear-resistant coating.

[0008] Preferably, a second sewage pipe is fixedly connected to the lower surface of the sewage ball, the interior of the second sewage pipe is communicated with the interior of the sealed cavity, a control valve is provided on the outer surface of the second sewage pipe, and a water transfer cavity is opened inside the sewage ball.

[0009] Preferably, a through hole is formed on the inner wall of the sealing cavity, the through hole extends into the interior of the water transfer cavity, and a sealing ring is fixedly connected to the inner wall of the through hole.

[0010] Preferably, the inner wall of the sealing ring is slidably connected to a limiting ring, and the outer surface of the limiting ring is provided with a water groove extending into the inner wall thereof.

[0011] Preferably, a baffle is fixedly connected to one end of the limiting ring close to the rotating shaft, and a spring is fixedly connected to a surface of one side of the baffle close to the limiting ring.

[0012] Preferably, the other end of the spring is fixedly connected to the sealing ring, and the outer surface of the sewage discharge ball is fixedly connected to a water delivery pipe, which extends into the interior of the water delivery cavity.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The kitchen waste sewage MBR membrane bioprocessor uses the propeller in the patent to transport the garbage to the inside of the sewage pipe when filtering the sewage. Since the garbage sediment is denser than the sewage, it will gradually settle. The precipitated impurities enter the inside of the sewage ball. Since the inside of the sealed chamber is divided into multiple sealed areas by six sealing plates, the impurities fall into one of the sealed areas. After a period of sedimentation, the second motor drives the rotating shaft to rotate. After the rotating shaft rotates, the sealing plate is driven to rotate synchronously. When the sealing plate rotates, since the multiple sealing plates are in a relatively static state, the sealing area moves with the movement of the sealing plate. When the sealing area moves to the bottom, it is discharged. Through the above structure, when the impurities in the sewage are discharged, there is no need to shut down and open the sealing cover, so that the processor can perform continuous sewage treatment, thereby indirectly improving the efficiency of sewage treatment and improving the practicality of the processor.

[0015] (2) The kitchen waste sewage MBR membrane bioprocessor injects water into the water supply chamber through a water supply pipe. When the water supply chamber is full of water, the pressure will gradually increase. The water pressure will squeeze the baffle to move. When the baffle moves, the spring will be stretched synchronously, and the movement of the baffle will simultaneously drive the limit ring to move. After the baffle moves, it will detach from the through hole and communicate with the inside of the water supply chamber through the water trough, so that water can flow in. Through the above structure, when cleaning the inside of the sewage ball, it only needs to transport water to the inside of the water supply chamber through the water supply pipe, which reduces the difficulty of cleaning the sewage ball and avoids impurities solidifying in the inside of the sealing chamber to cause sealing problems.

Since the garbage sediment is denser than the sewage, it will gradually settle. The precipitated impurities enter the inside of the sewage ball 6. Since the inside of the sealing chamber 7 is divided into multiple sealing areas by six sealing plates 9, the impurities fall into one of the sealing areas. After a period of sedimentation, the second motor 10 drives the rotating shaft 8 to rotate. After the rotating shaft 8 rotates, the sealing plate 9 is driven to rotate synchronously. When the sealing plate 9 rotates, since the multiple sealing plates 9 are in a relatively static state, the sealing area will move with the movement of the sealing plate 9, and will be discharged when the sealing area moves to the bottom. Through the above structure, when the impurities in the sewage are discharged, there is no need to shut down and open the sealing cover, so that the processor can perform continuous sewage treatment, thereby indirectly improving the efficiency of sewage treatment and improving the practicality of the processor.

[0025] Furthermore, the support assembly includes a support sleeve 11, which is sleeved on the outer surface of the second motor 10, and the outer surface of the first motor 5 is also sleeved with the support sleeve 11.

[0026] Working principle: When filtering sewage, the propeller in the patent is used to transport garbage to the inside of the sewage pipe 4. Since the garbage sediment is denser than the sewage, it will gradually settle. The precipitated impurities enter the inside of the sewage ball 6. Since the inside of the sealing chamber 7 is divided into multiple sealing areas by six sealing plates 9, the impurities fall into one of the sealing areas. After a period of sedimentation, the second motor 10 drives the rotating shaft 8 to rotate. After the rotating shaft 8 rotates, the sealing plate 9 is driven to rotate synchronously. When the sealing plate 9 rotates, since the multiple sealing plates 9 are in a relatively static state, the sealing area will move with the movement of the sealing plate 9. When the sealing area moves When the sealing area is aligned with the second sewage pipe 15, the impurities fall into the second sewage pipe 15 under the action of gravity. When the inside of the sealing chamber 7 needs to be cleaned after a long period of shutdown, water can be injected into the water delivery chamber 17 through the water delivery pipe 23. When the water inside the water delivery chamber 17 is full of water, the pressure will gradually increase, and the water pressure will squeeze the baffle 21 to move. When the baffle 21 moves, the spring 22 will be stretched synchronously, and the movement of the baffle 21 will synchronously drive the limit ring 20 to move. After the baffle 21 moves, it will disengage from the through hole 18, and the sealing chamber 7 is connected to the inside of the water delivery chamber 17 through the water groove 24, so that water can flow in.
