Description

Technical Field

[0001] This utility model relates to the field of anaerobic digester technology, and more specifically, to an anaerobic digester agitator. Background Technology

[0002] In existing technologies, an anaerobic digester agitator is a device used in anaerobic digesters. Its main function is to promote the uniform mixing of sludge in the anaerobic digester and improve digestion efficiency.

[0003] A significant problem with existing anaerobic digester mixers is their inability to achieve uniform sludge mixing. This directly leads to low anaerobic digestion efficiency. In traditional mixing systems, the mixing intensity is often insufficient or unevenly distributed, making it difficult to fully mix the sludge in the digester. This uneven mixing state has several negative effects: First, it leads to uneven temperature distribution within the digester, affecting the activity and growth of microorganisms; second, the distribution of nutrients is also uneven, resulting in insufficient nutrients for microorganisms in some areas.

[0004] Another prominent problem is that the installation and disassembly process of the stirring rod in the existing technology is complicated and time-consuming. The traditional method of fixing the stirring rod usually uses bolt connection or welding. These methods require a lot of time and manpower when replacing or maintaining the stirring rod. For example, when using bolt connection, the operator has to carry out tedious disassembly and installation work in a confined space, which not only increases the labor intensity but also prolongs the downtime of the equipment. For welding connection, the situation is even more complicated and may require professional welding equipment and technicians, which greatly increases the maintenance cost.

[0005] Furthermore, existing technologies generally suffer from the inability to effectively control sludge discharge after digestion. Traditional discharge systems often employ simple valve control or gravity discharge methods, which are difficult to precisely control the discharge speed and quantity. During the discharge process, there may be situations where a large amount of sludge suddenly surges out or discharge is obstructed. This not only affects the stability of subsequent treatment processes but may also cause environmental pollution. At the same time, due to the lack of an effective control mechanism, operators find it difficult to flexibly adjust the discharge parameters according to actual needs, which affects the continuity and efficiency of the entire digestion process.

[0041] In this embodiment, after the motor 15 starts, it transmits power to the stirring shaft 5 through the transmission assembly. The motor 15 outputs power through the drive wheel 16, which is connected to the driven wheel 17 via a transmission chain 18. The driven wheel 17 is mounted on the base frame 1. The other end of the connecting shaft 19, which is connected to the stirring shaft 5, is connected to the driven wheel 17.

The operation of the motor 15 drives the stirring shaft 5 to rotate. The stirring shaft 5 is rotatably mounted on the shaft seat 4, which is located on both sides of the mixing tank 3 to ensure the stable rotation of the stirring shaft 5. The stirring rod 6 is mounted on the outer wall of the stirring shaft 5 via a quick-clamping mechanism. As the stirring shaft 5 rotates, the stirring rod 6 performs stirring operations inside the mixing tank 3, causing the sludge to... Uniform mixing improves digestion efficiency. The stirring shaft 5 drives the stirring rod 6 to perform stirring operations in the mixing tank 3. The quick-clamping mechanism and locking assembly ensure the rapid installation and stable locking of the stirring rod 6. The feed pipe 14 at the top of the mixing tank 3 is used to input sludge into the mixing tank 3. When installing the stirring rod 6, the positioning rod 28 at the top of the clamping rod 7 is inserted into the positioning groove 29. The control sleeve 20 of the locking assembly is rotated to drive the inclined block sleeve 21 to abut against multiple sets of inclined push blocks 22, pushing the locking sleeve 13. Through the locking sleeve 13, multiple sets of locking blocks 12 are abutted, causing the sliding block 11 to slide along the clamping sleeve 9, pushing multiple sets of clamping blocks 10 to clamp into the clamping groove 8 to lock the clamping rod 7. Then, the rotating sleeve 24 is rotated to drive multiple sets of support rods 25 to drive multiple sets of limiting plates 26 to abut against and limit the two sides of multiple sets of limiting blocks 23.

[0042] Please see Figure 8As one implementation of the discharge mechanism: a discharge mechanism is provided at one end of the mixing tank 3. The discharge mechanism includes a discharge pipe 33, a rotating rod 34, a valve plate 35, a positioning plate 36, a handle 37, a positioning hole 38, and a positioning bolt 39. The discharge pipe 33 is installed on one side of the mixing tank 3. The rotating rod 34 is rotatably installed on the discharge pipe 33. The valve plate 35 is installed on the outer wall of the rotating rod 34. The positioning plate 36 is installed at the top of the discharge pipe 33. The handle 37 is installed at the top of the rotating rod 34. The positioning hole 38 is provided on the positioning plate 36 and the handle 37. The positioning bolt 39 is inserted into the positioning hole 38. The discharge mechanism controls the rotation of the rotating rod 34 and the valve plate 35 by rotating the handle 37, thereby adjusting the opening degree of the discharge pipe 33. The positioning plate 36, the positioning hole 38, and the positioning bolt 39 provide a locking function.

[0043] A connecting plate 40 is installed on the outer wall of the discharge pipe 33. The connecting plate 40 facilitates connection with other equipment and improves the scalability of the system.

[0044] More specifically, after the mixing process is completed, the discharge mechanism is in the closed state. At this time, the valve plate 35 is tightly fitted against the inner wall of the discharge pipe 33 to prevent sludge leakage. The positioning bolt 39 is inserted into the positioning hole 38 on the positioning plate 36 and the handle 37 to fix the position of the valve plate 35. The operator holds the handle 37 and rotates it clockwise or counterclockwise depending on the initial position of the valve plate 35. As the handle 37 rotates, the connecting rod 34 also rotates. The rotation of the rod 34 drives the valve plate 35 installed on its outer wall to rotate, gradually opening the discharge channel. By controlling the rotation angle of the handle 37, the operator can precisely adjust the opening degree of the valve plate 35, thereby controlling the discharge. The greater the rotation angle, the larger the opening, and the faster the discharge speed. As the valve plate 35 opens, the digested sludge in the mixing tank 3 is discharged through the discharge pipe 33 under the action of gravity. The connecting plate 40 may be used to connect subsequent conveying equipment or collection containers to ensure smooth and clean discharge process. When the sludge in the mixing tank 3 is discharged or reaches the predetermined amount, the operator rotates the handle 37 again to make the valve plate 35 fit against the inner wall of the discharge pipe 33 again, closing the discharge channel. In order to ensure the valve is closed, the operator re-inserts the positioning bolt 39 into the positioning hole 38 on the positioning plate 36 and the handle 37 to lock the position of the valve plate 35 and prevent accidental opening.

[0045] In summary, during the use or operation of the overall equipment: After the motor 15 starts, it transmits power to the stirring shaft 5 through the transmission assembly. The motor 15 outputs power through the drive wheel 16, which is connected to the driven wheel 17 via a transmission chain 18. The driven wheel 17 is mounted on the base frame 1. The other end of the connecting shaft 19, which is connected to the stirring shaft 5, is connected to the driven wheel 17. The power of the motor 15 is transmitted to the stirring shaft 5 through the transmission chain 18 and the connecting shaft 19, driving the stirring shaft 5 to rotate, which in turn drives the stirring rod 6 to perform stirring. The operation of the motor 15 drives the stirring shaft 5 to rotate. The stirring shaft 5 is rotatably mounted on the shaft seat 4, which is located on both sides of the mixing tank 3 to ensure the stable rotation of the stirring shaft 5. The stirring rod 6 is mounted on the outer wall of the stirring shaft 5 via a quick-clamping mechanism. As the stirring shaft 5 rotates, the stirring rod 6 performs stirring operations inside the mixing tank 3. This ensures uniform mixing of the sludge and improves digestion efficiency. The stirring shaft 5 drives the stirring rod 6 to perform stirring operations in the mixing tank 3. The quick-clamping mechanism and locking assembly ensure the rapid installation and stable locking of the stirring rod 6. The feed pipe 14 at the top of the mixing tank 3 is used to input sludge into the mixing tank 3. When installing the stirring rod 6, the positioning rod 28 at the top of the clamping rod 7 is inserted into the positioning groove 29. The locking assembly is rotated and the control sleeve 20 drives the inclined block sleeve 21 to abut against multiple sets of inclined push blocks 22, pushing the locking sleeve 13. Through the locking sleeve 13, multiple sets of locking blocks 12 abut against each other, causing the sliding block 11 to slide along the clamping sleeve 9, pushing multiple sets of clamping blocks 10 to clamp into the clamping groove 8 to lock the clamping rod 7. Then, the rotating sleeve 24 is rotated to drive multiple sets of support rods 25 to drive multiple sets of limiting plates 26 to abut against and limit the two sides of multiple sets of limiting blocks 23.

[0046] After the mixing process is completed, the discharge mechanism is in the closed state. At this time, the valve plate 35 is tightly fitted against the inner wall of the discharge pipe 33 to prevent sludge leakage. The positioning bolt 39 is inserted into the positioning hole 38 on the positioning plate 36 and the handle 37 to fix the position of the valve plate 35. The operator holds the handle 37 and rotates it clockwise or counterclockwise depending on the initial position of the valve plate 35. As the handle 37 rotates, the connected rotating rod 34 also rotates. The rotation of the rotating rod 34 drives the valve plate 35 installed on its outer wall to rotate, gradually opening the discharge channel. By controlling the rotation angle of the handle 37, the operator can precisely adjust the opening degree of the valve plate 35, thereby controlling the discharge speed. The larger the rotation angle, the larger the opening, and the faster the discharge speed. As the valve plate 35 opens, the digested sludge in the mixing tank 3 is discharged through the discharge pipe 33 under the action of gravity. The connecting plate 40 may be used to connect subsequent conveying equipment or collection containers to ensure smooth and clean discharge process. When the sludge in the mixing tank 3 is discharged or reaches the predetermined amount, the operator rotates the handle 37 again to make the valve plate 35 fit against the inner wall of the discharge pipe 33 again, closing the discharge channel. In order to ensure the valve is closed, the operator re-inserts the positioning bolt 39 into the positioning hole 38 on the positioning plate 36 and the handle 37 to lock the position of the valve plate 35 and prevent accidental opening.
