Description

Technical Field

[0001] This utility model relates to the field of anaerobic tower technology, specifically to an anaerobic tower that can prevent sludge calcification. Background Technology

[0002] An anaerobic digester is an anaerobic bioreactor used to treat high-concentration organic wastewater. It is typically cylindrical in shape and consists of, from bottom to top, an influent distribution system, a sludge bed, a suspended sludge layer, and a three-phase separator. Wastewater enters from the bottom of the digester and is evenly distributed across the entire cross-section of the reactor through the influent distribution system, ensuring full contact with the anaerobic microorganisms in the sludge bed. Under anaerobic conditions, the microorganisms decompose the organic matter in the wastewater into biogas, carbon dioxide, and water. Anaerobic digesters have advantages such as high treatment efficiency, low energy consumption, and low sludge production, and are widely used in the field of industrial wastewater treatment.

[0003] In anaerobic digesters, stirring is necessary to prevent sludge calcification. This is because stirring promotes thorough mixing of wastewater and sludge, ensuring uniform distribution of nutrients, acids, and alkalis, and preventing the accumulation of high-concentration substances that promote sludge calcification in certain areas. Existing stirring methods mainly involve mechanical stirring, which uses a motor to drive a stirring rod to move the liquid. However, in actual use, existing stirring rods often rotate around a drive rod, which is relatively inefficient in achieving uniform mixing. Due to gravity and the pressure from the upper sludge and liquid, the sludge at the bottom of the anaerobic digester has a high density and poor fluidity, causing it to accumulate at the bottom and leading to sludge calcification. Therefore, we propose an anaerobic digester that can prevent sludge calcification. Utility Model Content

[0004] The purpose of this invention is to provide an anaerobic tower that can prevent sludge calcification, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anaerobic tower capable of preventing sludge calcification, comprising a base, an anaerobic tower body mounted on the surface of the base, a stirring structure provided on the inner wall of the anaerobic tower body, the stirring structure comprising a support plate, the support plate being fixedly connected to the inner wall of the anaerobic tower body, a motor being fixedly connected to the surface of the support plate, a drive rod being fixedly connected to the output end of the motor, a plurality of stirring rods A being fixedly connected to the surface of the drive rod, a bevel gear A being fixedly connected to the end of the drive rod away from the motor, a fixing ring being fixedly connected to the arc surface of the drive rod, two circular rings being fixedly connected to the arc surface of the fixing ring, a circular rod being rotatably connected to the inner wall of the circular ring, a bevel gear B being fixedly connected to the end of the circular rod near the bevel gear A, and a plurality of stirring rods B being fixedly connected to the arc surface of the circular rod.

[0006] The effect achieved by the above components is as follows: through the coordinated work of each component in the stirring structure, the wastewater and sludge in the anaerobic tower are fully mixed, and nutrients, acid and alkaline substances are evenly distributed. This effectively avoids the accumulation of high-concentration substances that are conducive to sludge calcification in local areas, thereby achieving the purpose of preventing sludge calcification and improving the treatment effect of the anaerobic tower on high-concentration organic wastewater.

[0007] Preferably, a plurality of extension rods are fixedly connected to the surface of the stirring rod A, and a scraper is fixedly connected to the end of the extension rod away from the stirring rod A.

The scraper can scrape the sludge attached to the inner wall of the anaerobic tower body, prevent the sludge from accumulating on the tower wall, and further promote the mixing of sludge and wastewater.

[0009] Preferably, the arc surfaces of the round rod and the drive rod are fitted with a sealing cover, the sealing cover is fixedly connected to the drive rod, and the round rod rotates inside the sealing cover.

[0010] The effect achieved by the above components is that the sealing cover fitted on the arc surface of the round rod and the drive rod can prevent sludge and wastewater from entering the gap between the bevel gear A and the bevel gear B, avoid hindering the rotation, and ensure the stable operation of the stirring structure.

[0011] Preferably, the surface of the support plate is provided with a protective structure, the protective structure including a protective cover, the protective cover being fitted onto the surface of the motor, two limiting arms being fixedly connected to the arc surface of the protective cover, the surface of the limiting arms being provided with circular holes, two frames being fixedly connected to the surface of the support plate, the limiting arms being located within the frames, and pins slidingly penetrating the surface of the frames, the size of the pins being adapted to the size of the circular holes.

[0012] The effect achieved by the above components is as follows: by setting up a protective structure, the motor is prevented from being damaged by sewage and sludge inside the anaerobic tower. Sewage and sludge have a certain degree of conductivity and viscosity. After entering the motor, they may affect the electromagnetic environment inside the motor, interfere with the normal electromagnetic induction process of the motor, and cause unstable motor operation, such as speed fluctuations and abnormal noise. This ensures the working efficiency of the motor.

[0013] Preferably, a spring is fitted onto the arc surface of the pin, and the two ends of the spring are fixedly connected to the pin and the frame, respectively.

[0014] The effect achieved by the above components is that the spring improves the stability of the pin inserted into the round hole and prevents the pin from coming out of the round hole due to shaking.

If they enter the motor, they may affect the electromagnetic environment inside the motor, interfere with the normal electromagnetic induction process of the motor, and cause unstable motor operation, such as speed fluctuations and abnormal noise. This ensures the working efficiency of the motor. Attached Figure Description

[0029] Please see Figure 1-2 This utility model provides a technical solution: an anaerobic tower capable of preventing sludge calcification, comprising a base 1, an anaerobic tower body 2 mounted on the surface of the base 1, and a stirring structure 3 on the inner wall of the anaerobic tower body 2. Through the coordinated operation of the components in the stirring structure 3, the wastewater and sludge in the anaerobic tower are fully mixed, allowing nutrients, acids, and alkalis to be evenly distributed, effectively preventing the accumulation of high-concentration substances that promote sludge calcification in certain areas, thereby achieving the purpose of preventing sludge calcification and improving the treatment effect of the anaerobic tower on high-concentration organic wastewater. The surface of the support plate 301 is provided with a protective structure 4. By setting the protective structure 4, the motor 302 located inside the anaerobic tower is prevented from being damaged by sewage and sludge. Sewage and sludge have a certain degree of conductivity and viscosity. After entering the motor 302, they may affect the electromagnetic environment inside the motor 302, interfering with the normal electromagnetic induction process of the motor 302, leading to unstable operation of the motor 302, such as speed fluctuations and abnormal noise, thereby ensuring the working efficiency of the motor 302.

[0030] Reference Figure 3 and Figure 4 and Figure 5As shown in this embodiment: the stirring structure 3 includes a support plate 301, which is fixedly connected to the inner wall of the anaerobic tower body 2. A motor 302 is fixedly connected to the surface of the support plate 301. A drive rod 303 is fixedly connected to the output end of the motor 302. Several stirring rods A304 are fixedly connected to the surface of the drive rod 303. A bevel gear A307 is fixedly connected to the end of the drive rod 303 away from the motor 302. A fixing ring 308 is fixedly connected to the arc surface of the drive rod 303. Two circular rings 309 are fixedly connected to the arc surface of the fixing ring 308. A circular rod 310 is rotatably connected to the inner wall of the circular ring 309. A bevel gear B311 is fixedly connected to the end of the circular rod 310 near the bevel gear A307. Several stirring rods B312 are fixedly connected to the arc surface of the circular rod 310. Several extension rods 305 are fixedly connected to the surface of the stirring rod A304. A scraper 306 is fixedly connected to the end of each extension rod 305 away from the stirring rod A304. The extension rods 305 on the surface of the stirring rod A304 and the scraper 306 at the end function to scrape the sludge attached to the inner wall of the anaerobic tower body 2, preventing sludge from accumulating on the tower wall and further promoting the mixing of sludge and wastewater. The arc surfaces of the round rod 310 and the drive rod 303 are fitted with sealing covers 313. The sealing covers 313 are fixedly connected to the drive rod 303. The round rod 310 rotates inside the sealing covers 313. The sealing covers 313 fitted on the arc surfaces of the round rod 310 and the drive rod 303 can prevent sludge and wastewater from entering the gap between the bevel gear A307 and the bevel gear B311, avoiding obstruction to rotation and ensuring the stable operation of the stirring structure 3.

[0031] Reference Figure 6 and Figure 7 As shown, specifically, the protective structure 4 includes a protective cover 41, which is fitted onto the surface of the motor 302. Two limiting arms 42 are fixedly connected to the arc surface of the protective cover 41. Circular holes 43 are formed on the surface of the limiting arms 42. Two frames 44 are fixedly connected to the surface of the support plate 301. The limiting arms 42 are located within the frames 44. A pin 45 slides through the surface of the frame 44, and the size of the pin 45 matches the size of the circular hole 43. A spring 46 is fitted onto the arc surface of the pin 45. The two ends of the spring 46 are fixedly connected to the pin 45 and the frame 44, respectively. The spring 46 improves the stability of the pin 45 inserted into the circular hole 43, preventing the pin 45 from dislodging from the circular hole 43 due to shaking. A sealing ring 47 is fixedly connected to the surface of the support plate 301. A sealing gasket 48 is glued to the inner wall of the sealing ring 47. The protective cover 41 is inserted into the sealing ring 47. The sealing ring 47 and the sealing gasket 48 can prevent external moisture, dust and other impurities from entering the interior of the protective cover 41 and affecting the performance of the motor 302.

[0032] Working Principle: When operating this anaerobic tower that prevents sludge calcification, the motor 302 installed on the surface of the support plate 301 is first started. After the motor 302 starts working, its output end drives the drive rod 303 to rotate. During the rotation of the drive rod 303, several stirring rods A304 fixedly connected to its surface rotate accordingly. The stirring rods A304 will initially stir the wastewater and sludge in the anaerobic tower body 2, so that they are initially mixed. At the same time, the extension rods 305 on the surface of the stirring rods A304 and the scraper 306 at the end play their role. The scraper 306 can scrape the sludge attached to the inner wall of the anaerobic tower body 2, preventing sludge from accumulating on the tower wall and further promoting the mixing of sludge and wastewater. As the drive rod 303 rotates, the bevel gear A307 fixedly connected to the end away from the motor 302 also rotates synchronously. Due to the bevel gear Wheel A307 meshes with bevel gear B311. The rotation of bevel gear A307 drives bevel gear B311 to rotate. Since bevel gear B311 is fixedly connected to round rod 310, the round rod 310 rotates under the support of ring 309, which in turn drives several stirring rods B312 fixedly connected to the arc surface of the round rod 310 to rotate. The stirring rods B312 stir the wastewater and sludge from another direction, complementing the stirring of stirring rod A304, making the stirring more uniform and further improving the mixing degree of wastewater and sludge. During the stirring process, the sealing cover 313 fitted on the arc surface of round rod 310 and drive rod 303 can prevent sludge and wastewater from entering the gap between bevel gear A307 and bevel gear B311, avoiding obstruction to rotation and ensuring the stable operation of stirring structure 3.

[0033] The protective structure 4 on the surface of the support plate 301 protects the motor 302. When the motor 302 needs maintenance or repair, pull the pin 45 to disengage it from the round hole 43, and the protective cover 41 can be removed from the surface of the motor 302. During installation, put the protective cover 41 on the motor 302, so that the limiting arm 42 is located inside the frame 44. Release the pin 45, and under the elastic force of the spring 46, the pin 45 inserts into the round hole 43 to complete the fixation of the protective cover 41. At the same time, the sealing ring 47 and the sealing gasket 48 can prevent external moisture, dust and other impurities from entering the interior of the protective cover 41 and affecting the performance of the motor 302.
