The top of the connecting sleeve of the uppermost layer of stirring rods abuts against the shoulder, and a pressing plate sealing assembly is detachably connected to the bottom of the stirring shaft. The pressing plate sealing assembly abuts against the bottom of the connecting sleeve of the lowermost layer of stirring rods, thereby positioning each stirring rod on the stirring shaft; annular sealing grooves are respectively arranged on the top surfaces of the connecting sleeves of each stirring rod, and sealing members are respectively arranged in the sealing grooves.

[0007] Further, the connecting sleeve and the stirring shaft are connected by a flat key.

[0008] Further, the pressing plate sealing assembly includes a pressing plate and a cover plate. The pressing plate is fixedly connected to the bottom of the stirring shaft by screws, and the cover plate is fixedly connected to the bottom of the pressing plate by screws. Annular sealing grooves are also respectively arranged on the upper end surfaces of the pressing plate and the cover plate, and corresponding sealing members are also arranged in the sealing grooves.

[0009] Further, the rod bodies of adjacent two - layer stirring rods are arranged in a staggered manner.

[0010] The utility model adopts the above - mentioned technical solutions and has the following beneficial effects:

[0011] The stirring rod of the present utility model adopts an assembled structure, and the structure of each layer of the stirring rod is the same. To prevent the slurry from infiltrating into the stirring shaft and causing difficulty in disassembly, a sealing groove is provided on the upper surface of each layer of the stirring rod, and a sealing member is installed. Each layer of the stirring rod is installed on the stirring shaft, driven by a flat key, and the tail is pressed by a pressing plate, and finally sealed and protected by a cover plate. This structure is simple for stocking, and each layer of the stirring rod can be stacked and shipped during transportation, greatly saving transportation costs. Description of the Drawings

[0012] The following further describes the present utility model in detail in conjunction with the drawings and specific embodiments:

[0013] Figure 1 is a perspective view of the present utility model;

[0014] Figure 2 is a sectional view of the present utility model;

[0015] Figure 3 is a top view of the stirring rod;

[0016] Figure 4 is a sectional view of the stirring rod. Specific Embodiments

[0017] As Figures 1-4 shown, a stirrer for an ultrafine grinding wet mill of the present utility model includes a stirring shaft 1. The stirring shaft 1 is of a hollow structure, and there are multiple layers of stirring rods 2 provided on the stirring shaft 1. The structure of each layer of the stirring rod 2 is the same. The stirring rod 2 includes a connecting sleeve 21, and a plurality of rod bodies 22 are fixedly arranged at intervals along the circumferential direction on the outer circumferential surface of the connecting sleeve 21.

[0018] In order to fix the stirring rod 2, a shoulder 11 is provided in the middle of the stirring shaft 1. The connecting sleeves 21 of each stirring rod 2 are sleeved on the stirring shaft 1 layer by layer in sequence and rotate with the stirring shaft 1. The top of the connecting sleeve 21 of the uppermost layer of the stirring rod 2 abuts against the shoulder 11, and a pressing plate 3 sealing assembly is detachably connected to the bottom of the stirring shaft 1. The pressing plate 3 sealing assembly abuts against the bottom of the connecting sleeve 21 of the lowermost layer of the stirring rod 2, so as to position each stirring rod 2 on the stirring shaft 1.

[0019] To prevent the slurry from infiltrating into the stirring shaft 1 and causing difficulty in disassembly, an annular sealing groove 23 is respectively provided on the top surface of the connecting sleeve of each stirring rod 2, and a sealing member 24 is respectively installed in each sealing groove.

[0020] The connecting sleeve 21 of the stirring rod 2 is in driving connection with the stirring shaft 1 through a flat key 5.

[0021] The pressing plate 3 sealing assembly includes a pressing plate 3 and a cover plate 4. The pressing plate 3 is fixedly connected to the bottom of the stirring shaft 1 by screws, and the cover plate 4 is fixedly connected to the bottom of the pressing plate 3 by screws. Annular sealing grooves are also respectively provided on the upper end surfaces of the pressing plate 3 and the cover plate 4, and corresponding sealing members are also provided in the sealing grooves.
