Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment, specifically an anaerobic reaction mixer for wastewater treatment. Background Technology

[0002] Wastewater treatment requires a mixer to agitate the wastewater, ensuring it reacts fully with the reactants. Existing anaerobic reactor mixers consist of a reducer and a stirring rod, connected by a coupling. When the outer blades of the stirring rod are damaged after prolonged use, they need to be replaced. This can be done by disassembling the connecting parts, but since the blades and the shaft of the stirring rod are fixed, the stirring shaft cannot be reused after replacement, resulting in a waste of resources. Therefore, a device is urgently needed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide an anaerobic reactor mixer for wastewater treatment to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an anaerobic reaction mixer for sewage treatment, comprising a support plate and mixing blades, a fixing frame installed at the top of the support plate, a sealing gasket installed between the fixing frame and the support plate, a reducer fixedly installed at the top of the fixing frame, a rotating shaft fixedly installed at the output end of the reducer, and a fixing mechanism for conveniently fixing the mixing blades provided between the rotating shaft and the mixing blades;

[0005] The fixing mechanism includes a cavity, a threaded sleeve, a screw, a hollow cylinder, a pressing rod, a fixing ring, a spring, an inclined block, and a frustum block. The cavity is located inside the rotating shaft. The threaded sleeve is fixed at the top of the cavity. The screw is threadedly inserted into the threaded sleeve. The frustum block is fixed around the outside of the screw. The hollow cylinder is embedded and fixed to the outside of the rotating shaft. The fixing ring is fixed inside the hollow cylinder. The pressing rod is movably inserted into the center of the fixing ring. The inclined block is fixed to one side of the pressing rod. The spring is fixed between the inclined block and the fixing ring. In use, the stirring blade is sleeved on the outside of the rotating shaft. Then, the screw is rotated, causing it to move upward along the threaded sleeve, which in turn moves the frustum block upward. The frustum block presses against the inclined block, causing the inclined block to press against the inside of the stirring blade. Friction fixes the position of the stirring blade, and the spring is compressed. When the stirring blade needs to be replaced, the screw is rotated in the opposite direction, causing the frustum block to move downward. The spring then resets, causing the pressing rod to reset. Moving downward allows the stirring blade to be removed. This facilitates replacement and allows for the reuse of the rotating shaft.

[0006] Preferably, the lower end of the screw extends movably to the outside of the rotating shaft, and a rotating block is fixedly provided at the lower end of the screw to facilitate the rotation of the screw.

[0007] Preferably, several hollow cylinders are provided and symmetrically fixed on both sides of the rotating shaft.

[0008] Preferably, one side of the inclined block is a smooth inclined surface and is in close contact with the outer side of the frustum block.

[0009] Preferably, the outer surface of the frustum block is a smooth surface.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] In use, the stirring blade is fitted onto the outside of the rotating shaft. Then, the screw is rotated, causing it to move upward along the screw sleeve, which in turn moves the frustum block upward. The frustum block presses against the tilting block, which in turn moves the pressing rod to press against the inside of the stirring blade. The stirring blade is fixed in position by friction, and the spring is compressed. When the stirring blade needs to be replaced, the screw is rotated in the opposite direction, causing the frustum block to move downward. The spring then returns to its original position, causing the pressing rod to return to its original position. Moving the blade downward allows it to be removed. This method facilitates replacement and allows for the reuse of the rotating shaft. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides an anaerobic reaction mixer for sewage treatment, including a support plate 1 and a stirring blade 4. A fixing frame 5 is bolted to the top of the support plate 1. A sealing gasket 6 is installed between the fixing frame 5 and the support plate 1. A reducer 2 is fixed to the top of the fixing frame 5 by a mounting bracket. A rotating shaft 3 is fixed to the output end of the reducer 2 by a coupling. A fixing mechanism is provided between the rotating shaft 3 and the stirring blade 4 to facilitate fixing the stirring blade 4. The fixing mechanism includes a cavity 7, a screw sleeve 8, a screw 9, a hollow cylinder 10, a pressing rod 12, a fixing ring 11, a spring 14, an inclined block 13, and a frustum block 15. The cavity 7 is opened inside the rotating shaft 3. The screw sleeve 8 is welded and fixed to the top position inside the cavity 7. The screw 9 is threaded through the screw sleeve 8. The lower end of the screw 9 extends movably to the outside of the rotating shaft 3.

[0018] A rotating block is welded to the lower end of the screw 9 for easy rotation. A frustum block 15 is welded to the outside of the screw 9, and its outer surface is smooth. A hollow cylinder 10 is embedded and fixed to the outside of the rotating shaft 3. Several hollow cylinders 10 are symmetrically fixed on both sides of the rotating shaft 3. A fixing ring 11 is welded and fixed inside the hollow cylinder 10. A pressing rod 12 is movably inserted through the center of the fixing ring 11. An inclined block 13 is welded and fixed to one side of the pressing rod 12. One side of the inclined block 13 is a smooth inclined surface and is tightly attached to the outside of the frustum block 15. A spring 14 is welded and fixed between the inclined block 13 and the fixing ring 11. During use, the stirring... The mixing blade 4 is sleeved on the outside of the rotating shaft 3. Then, the screw 9 is rotated, causing the screw 9 to move upward along the screw sleeve 8, which drives the frustum block 15 to move upward. The frustum block 15 presses the inclined block 13, which in turn drives the extrusion rod 12 to press the inner side of the mixing blade 4. The position of the mixing blade 4 is fixed by friction, and the spring 14 is in a compressed state. When the mixing blade 4 needs to be replaced, the screw 9 is rotated in the opposite direction, causing the frustum block 15 to move downward. At this time, the spring 14 returns to its original position, which drives the extrusion rod 12 to return to its original position. The mixing blade 4 can then be removed by moving downward. This makes replacement convenient and also facilitates the reuse of the rotating shaft 3.

[0019] Working principle: In use, the stirring blade 4 is sleeved on the outside of the rotating shaft 3. Then, the screw 9 is rotated, causing the screw 9 to move upward along the screw sleeve 8, which drives the frustum block 15 to move upward. The frustum block 15 presses the inclined block 13, which in turn drives the pressing rod 12 to press the inside of the stirring blade 4. The stirring blade 4 is fixed in position by friction, and the spring 14 is in a compressed state. When the stirring blade 4 needs to be replaced, the screw 9 is rotated in the opposite direction, causing the frustum block 15 to move downward. At this time, the spring 14 returns to its original position, which drives the pressing rod 12 to return to its original position. The stirring blade 4 can then be removed by moving it downward. This makes replacement convenient and also facilitates the reuse of the rotating shaft 3.
