Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage UASB anaerobic tower. Background Art

[0002] The UASB process, also known as the upflow anaerobic sludge blanket process, is a high-speed biological wastewater treatment process that utilizes a high-concentration sludge bed at the bottom of the reactor to perform anaerobically treatment on upflowing wastewater. The UASB anaerobic tower, the core device of UASB technology, is a tall cylindrical container filled with anaerobic granular sludge. Sewage enters the tower from the bottom and flows upward through the sludge bed, where it comes into contact with the microorganisms present in the sludge, completing the anaerobic reaction. The methane gas produced during the reaction is collected and used as an energy source. UASB anaerobic towers are commonly used in wastewater treatment to decompose organic matter and reduce its chemical oxygen demand (COD) and biochemical oxygen demand (BOD). The use of UASB anaerobic towers can remove harmful substances from wastewater, reduce environmental pollution, and protect the health of water bodies and ecosystems. Biogas can also be used as an energy source, enabling resource recycling.

[0003] When sewage is treated by a UASB anaerobic tower, the sewage generally enters the tower through the water inlet pipe and reacts with the microorganisms in the sludge to achieve purification. Since the sewage contains some impurity particles, the impurities in the sewage cannot be removed well during the reaction, so the impurities will enter with the sewage, which can easily cause the water inlet pipe and water distributor to become blocked, affecting the inflow and distribution of sewage, and thus failing to ensure the quality and efficiency of the sewage reaction.

[0022] The motor 33 used in this application is a product that can be directly purchased on the market. Its principle and connection method are existing technologies well known to those skilled in the art, so they will not be described here in detail.

[0023] The sewage UASB anaerobic tower includes a shell, which includes a tower body 1. A water inlet pipe 11 is fixedly connected to the surface of the tower body 1.

The water inlet pipe 11 allows sewage to enter the inner side of the tower body 1. The water distributor 12 allows sewage to be evenly distributed in the tower body 1. The upstream sludge can contact the sludge in the anaerobic sludge bed 13 and the deep purification reaction chamber 15, and undergo anaerobic reaction with the microorganisms in the sludge. The anaerobic microorganisms decompose organic matter under anaerobic conditions and convert it into inorganic matter, thereby achieving sewage purification.

[0024] The surface of the water inlet pipe 11 is provided with a debris removal mechanism, which includes a filter box 2, which is fixedly connected to the surface of the water inlet pipe 11, and a filter plate 21 is movably connected to the inner side of the filter box 2, and the top of the filter plate 21 is fixedly connected to the connecting plate 22, and the lower surface of the connecting plate 22 is fixedly connected to the positioning block 23. A positioning groove 24 is provided on the inner side of the filter box 2, and a movable groove 25 is provided on the inner side of the positioning block 23. The movable groove 25 is provided on the inner side of the connecting plate 22 and the positioning block 23, and an insert block 210 is movably connected to the inner side of the movable groove 25. A slot 211 is provided on the inner wall of the positioning groove 24. Through the setting of the filter plate 21, impurities in the sewage can be filtered and intercepted, thereby preventing impurities from entering and causing blockage of the water inlet pipe 11 and the water distributor 12, thereby ensuring the entry and full reaction of sewage.

[0025] Furthermore, the impurity removal mechanism also includes a pull rod 26, which is movably connected to the inner side of the movable groove 25, and the pull rod 26 and the connecting plate 22 are movably connected. The top end of the pull rod 26 is fixedly connected to the connecting rod 27, and the bottom end of the pull rod 26 is fixedly connected to the connecting block 28. The surface of the connecting block 28 is movably connected to a movable rod 29, and the upper surface of the connecting block 28 is fixedly connected to a spring 212. The surface of the connecting plate 22 is fixedly connected to a sealing gasket 213. The connecting block 28 and the plug block 210 are connected by the movable rod 29, so that when the movable rod 29 moves, the plug block 210 moves accordingly and can be inserted into and separated from the slot 211, thereby facilitating the fixing or disassembly of the filter plate 21 and the filter box 2, and facilitating the removal of the filter plate 21 for cleaning or replacement, which can ensure the effect of the filter plate 21 in filtering impurities.

[0026] Furthermore, the positioning blocks 23 are in two groups and fixedly connected to the connecting plate 22, and the positioning grooves 24 are in two groups opened on the inner side of the filter box 2. One end of the movable rod 29 is movably connected to the connecting block 28 through a rotating shaft, and the other end of the movable rod 29 is movably connected to the insert block 210 through a rotating shaft. By setting the positioning blocks 23 and the positioning grooves 24, the connection plate 22 can be positioned, thereby avoiding the installation of the filter plate 21 from being skewed and misplaced, and ensuring the use effect of the filter plate 21.

[0027] Furthermore, one end of the spring 212 is fixedly connected to the movable groove 25, and the other end of the spring 212 is fixedly connected to the connecting block 28. Through the setting of the spring 212, the connecting block 28 can be reset, and then the movable rod 29 can drive the plug block 210 to reset under the action of the connecting block 28, thereby realizing the insertion of the plug block 210 and the slot 211, making it more convenient to fix the filter box 2.

[0028] Furthermore, a disturbance mechanism is provided on the inner side of the anaerobic sludge bed 13, and the disturbance mechanism includes a first fixed rod 3, which is fixedly connected to the inner wall of the tower body 1, and a fixed block 31 is fixedly connected to the end of the first fixed rod 3 away from the tower body 1, and a rotating rod 32 is movably connected to the inner side of the fixed block 31, and a motor 33 is fixedly installed on the inner side of the fixed block 31, and a second fixed rod 34 is fixedly connected to the surface of the rotating rod 32, and a fixed plate 35 is fixedly connected to the surface of the second fixed rod 34. Through the arrangement of the first fixed rod 3 and the fixed block 31, the rotating rod 32 and the motor 33 can be supported, so that the motor 33 can drive the rotating rod 32 to rotate, thereby realizing the disturbance of the sewage and sludge by the fixed plate 35, which is beneficial to improving the efficiency of the anaerobic reaction.

[0029] Furthermore, the rotating rod 32 is fixedly connected to the output end of the motor 33, and the second fixed rods 34 are fixedly connected to the rotating rod 32 in eight groups. The two groups of second fixed rods 34 are correspondingly connected to the fixed plate 35.

[0030] Working principle: When in use, the filter plate 21 is set to intercept and filter impurities in the sewage. When the filter plate 21 needs to be cleaned and replaced, by pulling the connecting rod 27, the pull rod 26 will move inside the movable groove 25 under the action of the connecting rod 27, and the connecting block 28 will rise to drive the movable rod 29 to move, and then the insert block 210 will move inside the movable groove 25 and separate from the slot 211, realizing the release of the fixation of the positioning block 23 and the filter box 2. At this time, the spring 212 is in a contracted state, and then the connecting plate is pulled 22, the filter plate 21 can be pulled out from the filter box 2; when the filter plate 21 needs to be used, the filter plate 21 is inserted into the filter box 2, and the positioning block 23 is inserted into the positioning groove 24, and then the connecting rod 27 is loosened. The connecting block 28 will be reset under the rebound action of the spring 212, and then the movable rod 29 drives the plug 210 to reset, so that the plug 210 and the slot 211 are inserted and connected, and the connecting plate 22 can be fixed. At this time, the sealing gasket 213 and the filter box 2 are tightly fitted to achieve a seal, and the filter plate 21 can be used;

[0031] The motor 33 is electrically connected to an external power source. The staff starts the motor 33 by pressing the switch. The operation of the motor 33 drives the rotating rod 32 to rotate. The second fixed rod 34 will drive the fixed plate 35 to rotate under the action of the rotating rod 32. The rotation of the fixed plate 35 can disturb the sewage, making the sewage more dispersed, and the sewage can better contact with the microorganisms in the sludge, thereby improving the effect and efficiency of the reaction.
