Abstract
Description
Technical Field
[0001] The invention relates to the technical field of stirring, in particular to a dispersing disc stirring device for a dispersing kettle. Background Art
[0002] Dispersion kettles require extended use, and the agitator discs rotate constantly to disperse the contents. The agitator shaft and agitator disc are welded together, and this weld is susceptible to cracking during prolonged rotation. The agitator disc can become partially cracked and hang from the agitator shaft, or even completely crack and fall, causing dispersing and stirring to fail. In even worse cases, the agitator shaft can be pulled along and bend. If cracking occurs during operation, the weld between the agitator disc and the agitator shaft can lead to dispersing and stirring failure, potentially damaging the agitator shaft and agitator disc. Therefore, a new solution is urgently needed to address these technical issues. Summary of the Invention
[0003] To address the above-mentioned issues, the present invention discloses a dispersing disc agitator for a dispersing kettle, comprising a stirring shaft, a dispersing disc fixedly connected to the lower end of the stirring shaft, and a plurality of stirring teeth fixedly connected to the edge of the dispersing disc. The stirring teeth are bent upward or downward, and the upwardly bent stirring teeth and the downwardly bent stirring teeth are staggered. The stirring teeth on the dispersing disc achieve a stirring and dispersing effect on the material in the reactor as the stirring shaft rotates.
[0004] The lower end of the agitator shaft is provided with a flat washer, with a bolt inserted through the middle of the flat washer. The bolt threadably engages with a pre-set threaded hole at the end of the agitator shaft. Once the dispersion plate is mounted on the agitator shaft, the bolt and flat washer secure the dispersion plate to the agitator shaft, effectively securing it. Compared to traditional welding methods, this method reduces the risk of failure and makes replacement of the dispersion plate easier.
[0005] Preferably, connecting plates are provided above and below the dispersion disc, which clamp the dispersion disc in the middle and ensure the stability of the dispersion disc after the flat gasket is installed.
[0006] Preferably, the inner wall of the opening in the center of the dispersion disc and the connecting plate and the side wall of the stirring shaft are all provided with keyways, and the inner part of the keyways is matched with a flat key. The use of the flat key avoids the problem of slipping between the dispersion disc and the rotating shaft.
[0007] The beneficial effects of the present invention are as follows: the dispersion disk is fixed by a connection method of bolts, flat washers and matching flat keys, which is more stable than the traditional welding method of fixing the dispersion disk. At the same time, it can avoid the dispersion disk from being used for a short time and the bending and deformation of the stirring shaft, reduce the company's maintenance costs, and improve economic benefits.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inward" and "outward" refer to directions toward or away from the geometric center of a particular component, respectively.
[0015] like Figures 1 to 4 As shown, a dispersion disc stirring device for a dispersion kettle includes a stirring shaft 4. The stirring shaft 4 is a stepped shaft, and its upper end is connected to the output end of the driving motor through gears, pulleys, etc. The lower end of the stirring shaft 4 is fixedly connected to a dispersion disc 5. The dispersion disc 5 is circular, and a plurality of stirring teeth 6 are fixedly connected to the edge of the dispersion disc 5. The stirring teeth 6 are bent upward or downward, and the stirring teeth 6 bent upward and the stirring teeth 6 bent downward are staggered. When the dispersion disc 4 rotates with the stirring shaft 4, the stirring teeth 6 "bump" / "cut" the material.
[0016] A flat gasket 1 is provided at the lower end of the stirring shaft 4. The flat gasket 1 is a circular gasket ring. A bolt 2 is inserted into the middle of the flat gasket 1. The bolt 2 is threadedly fitted into a preset threaded hole at the end of the stirring shaft 4. When the flat gasket 1 is fixed to the stirring shaft 4 by the bolt 2, the flat gasket 1 supports and fixes the dispersion plate 5 above.
[0017] Connecting plates 3 are provided above and below the dispersion disk 5 , and the two connecting plates 3 clamp the dispersion disk 5 in the middle.
[0018] The inner walls of the openings in the center of the dispersion disk 5 and the connecting plate 3 and the side walls of the stirring shaft 4 are all provided with keyways, and the interior of the keyways is fitted with flat keys to ensure that the stirring shaft 4 and the dispersion disk 5 do not slip.
[0019] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above-mentioned embodiment, but also include technical solutions composed of any combination of the above technical features.
