When the stirring blade is damaged, the damaged stirring blade can be replaced, thereby reducing the maintenance cost; secondly, all the stirring blades are connected to form a ring-shaped whole through the connecting edge of the arc plate, and the first tooth pattern, the second tooth pattern and the first elastic layer are provided to increase the friction between the arc plate and the stirring rod, further improving the firmness and stability of the installation, and the structure is simple and easy to disassemble and assemble.

[0005] Furthermore, the number of stirring blades is 3.

[0006] Furthermore, the connecting edges of adjacent arc-shaped plates are connected by bolts, and the second elastic sheet is pressed between the connecting edges of adjacent arc-shaped plates, thereby further improving the firmness of the connection between adjacent arc-shaped plates, and the structure is simple and easy to assemble and disassemble.

[0007] Furthermore, the stirring blade is in an arc shape, and the stirring blade is obliquely connected to the arc plate.

[0008] To sum up, the beneficial effects of the utility model are: this product can replace damaged mixing blades, thereby reducing maintenance costs; an arc-shaped plate and a connecting edge are also designed, so that the mixing blades can be connected into one, and pressed tightly against the outer wall of the mixing rod, and then through the first tooth pattern, the tooth pattern, and the first elastic layer, the mixing blade ensures the firmness and stability of the connection between the mixing blade and the mixing rod, and is also convenient for disassembly and assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 2 It is a partial structural schematic diagram of the utility model;

[0011] Among them, there are a stirring rod 1 ; a stirring blade 2 ; an arc plate 3 , a connecting edge 31 , a second tooth pattern 32 , a first elastic layer 33 , a first tooth pattern 34 ; a second elastic sheet 4 ; and a bolt 5 . DETAILED DESCRIPTION

[0012] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0013] like Figure 1 and 2 As shown, a detachable sewage agitator includes a stirring rod 1 and three stirring blades 2 for stirring sewage. In other embodiments, the number of stirring blades 2 can also be designed as needed. The top of the stirring rod 1 is connected to a motor, and the stirring blades 2 are evenly distributed on the outer wall of the bottom end of the stirring rod 1. The stirring rod 1 and the motor are selected from existing products, and the motor is no longer within the protection scope of this product. The connection method between the motor and the stirring rod can be snap-on, plug-in, threaded connection, etc. The stirring blade 2 is arc-shaped.

[0014] The improvement of the present product lies in that: each end of the stirring blade 2 is welded to an arc plate 3, that is, the arc plate 3 also consists of three pieces, and the stirring blades 2 are preferably connected to the arc plate 3 at an angle in one direction, and each arc plate 3 is bent into a circle, and the arc plate 3 is close to the outer wall of the stirring rod 1, and the left and right ends of the arc plate 3 are bent outwardly toward the stirring rod 1 to form a connecting edge 31, and the left and right ends of all the arc plates 3 are detachably connected to form a ring through the connecting edges 31 in sequence, that is, the connecting edges of adjacent arc plates 3 are connected by bolts 5, and the second elastic sheet 4 is pressed between the connecting edges of adjacent arc plates 3, and the second elastic sheet 4 is made of rubber material.

[0015] The surface of the arc plate 3 close to the stirring rod 1 is provided with a first tooth pattern 34, and the surface of the stirring rod 1 is provided with a second tooth pattern 32 close to the first tooth pattern 34, and the first elastic layer 33 is pressed between the first tooth pattern 34 and the second tooth pattern 32. The first tooth pattern 34 and the second tooth pattern 32 are both sawtooth-shaped, and the first elastic layer 33 is preferably made of rubber material, and the second elastic layer 33 is preferably made of a rubber ring.

[0016] During installation, align the connecting edges 31 at the left and right ends of the three arc-shaped plates 3 in sequence and then insert bolts, a total of three bolts, and connect the left and right ends of each arc-shaped plate with a bolt, do not tighten, then the three arc-shaped plates 3 are surrounded in a ring, and then put on the outer periphery of the bottom end of the stirring rod 1, so that the first tooth pattern 34 is aligned with the second tooth pattern 32, and then the first elastic layer 33 is placed between the first tooth pattern 34 and the second tooth pattern, and then the three bolts are tightened in sequence, thereby driving the three arc-shaped plates 3 to press the stirring rod 1, that is, the first tooth pattern 34 and the first elastic layer 33 are on the second tooth pattern 32, and the installation is completed. Start the motor, the motor drives the stirring rod to rotate, and then drives the stirring blade to rotate and stir the sewage. When the stirring blade is damaged, you only need to remove the bolts and replace the corresponding stirring blade, which greatly reduces the maintenance cost.

[0017] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
