Description

Stirring device

The present invention relates to a power machine, and more particularly to a stirring machine.

Referring to Fig. 1, a conventional agitating device 1 includes a motor 11, a speed reducer 12 coupled to the motor 11, a coupling 13 coupled to the speed reducer 12, and a stirring shaft 14 coupled to the coupling 13. The agitator shaft 14 has a plurality of blades 15 .

In practical application, the speed reducer 12 is used to reduce the output speed of the motor 11, and the coupling shaft 13 is driven to rotate by the coupling 13 to drive the blade 15 to agitate the fluid 100 to fully mix the fluid 100 or the fluid. 100 fully responded.

However, the agitating shaft 14 is only supported by the coupling 13 and the other end lacks strong support. Therefore, the reaction force of the agitating fluid 100 and the generated turbulence are completely borne by the agitating shaft 14 at the coupling 13. As a result, the agitating shaft 14 is easily broken by the coupling 13, and the overall service life is short.

Therefore, the object of the present invention is to provide a stirring device which is excellent in strength and has a long service life.

Therefore, the novel stirring device comprises a stirring unit, a driving unit for driving the stirring unit, and a supporting unit spaced apart from the driving unit for pivoting the stirring unit.

The agitating unit includes a stirring shaft, and a plurality of blades extending radially outward from the agitating shaft, the agitating shaft having an opposite driving end and a supporting end. The driving unit is a driving end connected to the stirring shaft to drive the stirring shaft to rotate. The support unit is pivoted for the support end of the agitator shaft.

The utility model has the advantages that the supporting unit is pivoted for the supporting end of the stirring shaft, and the supporting point of the stirring shaft can be increased to increase the overall strength, so as to reduce the reaction force of the stirring shaft and the generated reaction force. The turbulence, the resulting fatigue stress caused by the swing, thereby increasing the service life.

Referring to Figures 2 and 3, an embodiment of the present agitating device 2 includes a stirring unit 3, a driving unit 4 coupled to the agitating unit 3 to drive the agitating unit 3, and a drive unit 4 spaced from the driving unit 4 in the fluid 200. The support unit 5 is provided for the agitation unit 3 to be pivoted.

The agitating unit 3 includes a stirring shaft 31 and a plurality of blades 32 extending radially outward from the agitating shaft 31. The agitating shaft 31 has an opposite driving end 311 and a supporting end 312.

The driving unit 4 includes a motor 41, a speed reducer 42 connected to the motor 41, and a coupling 43 connecting the driving end 311 of the stirring shaft 31 and the speed reducer 42.

The support unit 5 includes a base 51 , a support base 52 detachably coupled to the base 51 , a mount 53 detachably coupled to the support base 52 , and a bearing 54 disposed in the mount 53 . A bearing 54 for communicating the liquid 56 into the bearing 54 of the bearing 54 and a set of water sealing rings 57 disposed at the supporting end 312 and covering the bearing 54 are provided. The support end 312 of the agitating shaft 31 is placed through the bearing 54 to rotate relative to the mounting seat 53. In this embodiment, the base 51, the support base 52 and the mounting base 53 are screwed to each other.

By using the supporting unit 5 for pivoting the supporting end 312 of the stirring shaft 31, the supporting point of the stirring shaft 31 can be increased to increase the overall strength, so as to reduce the reaction force of the stirring end 31 of the stirring shaft 31 due to the reaction force of the fluid 200. The fatigue stress caused by the oscillation caused by the turbulence. The liquid inlet 56 is used to input the liquid 56 into the bearing 54 to not only lubricate the bearing 54 but also to generate a positive pressure in the bearing 54 to fit the water seal that is sleeved on the support end 312 and covers the bearing 54. The ring 57 effectively prevents impurities in the fluid 200 from entering the bearing 54 and causing wear, thereby increasing the service life.

Moreover, since the support base 52 is separable from the base 51 and the mount 53, the support base 52 is separated from the base 51 and the mount 53 to laterally support the support base 52. With the removal, the mount 53 can be moved downward to facilitate the replacement of the bearing 54, without lifting the entire agitator shaft 31.

In summary, the stirring device 2 of the present invention is configured to pivot the supporting end 312 of the stirring shaft 31 by using the supporting unit 5, and the supporting point of the stirring shaft 31 can be increased to increase the overall strength to reduce the supporting end of the stirring shaft 31. Because of the reaction force generated by the reaction force of the fluid 200 and the disturbing flow caused by the fluid 200, the fatigue stress caused by the swing, thereby increasing the service life, can indeed achieve the purpose of the present invention.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
