[0025] During operation, the stirring device 10 in the current sewage treatment stirring aeration device cannot be disassembled and is usually fixedly connected to the aeration device to prevent it from falling off during stirring. However, when a large amount of sludge is attached to the stirring device and cannot be cleaned in time, the stirring device may be damaged. When the stirring device 10 fails, it is difficult to disassemble and repair the device. The installation pipe 1 is placed at the bottom of the sewage pool, and the whole is an aeration device. When the stirring device 10 needs to be installed, the card slot 15 at the bottom of the stirring device 10 is connected to the card block 14 at the top of the motor 4, and the stirring device 10 is connected to the stirring device 10. The fixing hole inside the fixing block 11 on the outer side of the bottom end of the device 10 is aligned with the top of the screw 9. At this time, rotating the rotating block 13 drives the screw 7 to rotate inside the rotating groove 6. At this time, the moving block 8 rises with the rotation of the screw 7, and the screw 9 rises and the top of the screw 7 passes through the round hole 12. At this time, the bolt 100 is threadedly connected to the outside of the screw 9 to complete the fixation of the mixing device 10. As the motor 4 is turned on, the block 14 rotates to drive the entire mixing device 10 to rotate to achieve mixing. At the same time, the working column 5 rotates with the slider 18 inside the T-shaped surrounding groove 17.
[0026] The fixing mechanism is provided with two groups, and the two groups of fixing mechanisms are arranged outside the connecting seat 2;
[0027] During operation, the two sets of fixing mechanisms enable the stirring device 10 to be fixed to the mounting base more firmly, and will not fall off during rotation.
[0028] The moving block 8 is completely inside the rotating groove 6, and the size of the moving block 8 is adapted to the rotating groove 6;
[0029] During operation, because the size of the moving block 8 matches the inner size of the rotating groove 6 , the moving block 8 does not rotate together with the screw rod 7 but moves up and down.
[0030] The output end of the motor 4 is fixedly connected with a block 14, and the bottom end of the stirring device 10 is provided with a slot 15, the size of the block 14 matches the size of the slot 15, and the block 14 is inside the slot 15;
[0031] During operation, the block 14 at the bottom of the stirring device 10 is connected to the slot 15 to position the stirring device 10 . The size of the block 14 matches the size of the slot 15 , which can drive the stirring device 10 when the block 14 rotates, so that it can rotate normally.
[0032] A sliding pad 16 is provided at the top of the connecting seat 2, and the sliding pad 16 is fixedly connected to the connecting seat 2;
[0033] During operation, the sliding pad 16 can reduce the friction between the stirring device 10 and the connecting seat 2, so that the stirring device 10 can rotate normally.
[0034] A T-shaped surrounding groove 17 is formed on the outer side of the connecting seat 2, and a slider 18 is slidably connected to the T-shaped surrounding groove 17, and the slider 18 is fixedly connected to the working column 5;
[0035] During operation, because the stirring device 10 is connected to the working column 5 through the fixed column outside the stirring device 10 and the screws 9 and bolts 100 inside the working column 5, the stirring device 10 will drive the working column 5 to rotate when it rotates, and the sliding block 18 and the T-shaped surrounding groove 17 are slidably connected, so that the working column 5 can rotate around the connecting seat 2 while rotating with the stirring device 10.
[0036] Working principle: the stirring device 10 in the stirring and aerating device cannot be disassembled and is usually fixedly connected to the aerating device to prevent it from falling off during stirring. However, when a large amount of sludge is attached to the inside of the stirring device and cannot be cleaned in time, the stirring device may be damaged. When the stirring device 10 fails, the device is difficult to disassemble and repair. The installation pipe 1 is placed at the bottom of the sewage pool, and the whole is an aerating device. When the stirring device 10 needs to be installed, the slot 15 at the bottom of the stirring device 10 is connected to the block 14 at the top of the motor 4, and the fixing hole inside the fixing block 11 on the outside of the bottom of the stirring device 10 is aligned with the top of the screw 9. At this time, rotating the rotating block 13 drives the screw 7 to rotate. The groove 6 rotates inside, and the moving block 8 rises with the rotation of the screw 7. Because the size of the moving block 8 is compatible with the internal size of the rotating groove 6, the moving block 8 does not rotate together with the screw 7 but moves up and down, and the screw 9 rises and the top of the screw 7 passes through the round hole 12. At this time, the bolt 100 is threadedly connected to the outside of the screw 9 to complete the fixation of the stirring device 10, and as the motor 4 is turned on, the block 14 rotates to drive the entire stirring device 10 to rotate to achieve stirring. The working column 5 and the slider 18 simultaneously rotate inside the T-shaped surrounding groove 17. The sliding pad 16 can reduce the friction between the stirring device 10 and the connecting seat 2, so that the stirring device 10 rotates normally.
[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
