Description

Technical Field

[0001] The utility model relates to the field of environmental protection, and particularly relates to a deep - pool mixer. Background Art

[0002] Due to the relatively long stirring shaft of the deep - water mixer, if the manufacturing and installation precision is not high enough, the axes of the underwater bearing and the motor shaft will be deflected. It is difficult to avoid this error during actual installation, and it is impossible to ensure that the axes of the underwater bearing and the motor shaft are completely coaxial. Moreover, in the past, the motor and the main shaft were connected by a rigid coupling, and the installation precision was not high enough. When the coaxiality deviation between the motor shaft and the main shaft is too large, when the motor rotates, the motor will swing left and right along the diagonal line of the main shaft, causing the frame to also swing violently, and ultimately resulting in the destruction of the machine. Content of the Utility Model

[0003] The purpose of the utility model is to provide a deep - pool mixer to solve the problems mentioned in the background art.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A deep - pool mixer, comprising an above - water driving assembly, a stirring shaft and an underwater supporting assembly; the stirring shaft is connected between the above - water driving assembly and the underwater supporting assembly; the above - water driving assembly includes a mounting seat, a driving device, a roller chain coupling, a tapered roller bearing and an upper shaft head; the driving device is installed above the mounting seat and the output shaft is arranged downward; the upper shaft head is installed at the lower part of the mounting seat through the tapered roller bearing and is coaxially arranged with the output shaft; the roller chain coupling connects the lower end of the output shaft and the upper end of the upper shaft head; the upper end of the stirring shaft is fixedly connected with the upper shaft head, and the lower end is installed with a lower shaft head; the lower shaft head is rotationally connected with the underwater supporting assembly; several groups of stirring blades are arranged up and down on the outer periphery of the stirring shaft.

[0006] For a further description of the utility model, the tapered roller bearing is fixed on the mounting seat through a bearing seat.

[0007] For a further description of the utility model, the driving device adopts a cycloid pinwheel speed reducer.

[0008] For a further description of the utility model, the underwater supporting assembly includes an underwater bearing mounting plate and an underwater bearing; the underwater bearing is fixed above the underwater bearing mounting plate; the lower shaft head is rotationally connected in the underwater bearing.

[0011] The beneficial effects of the present utility model are as follows:

[0012] This design uses a roller chain coupling to connect the output shaft and the upper shaft head, allowing a small radial deviation in the axial line between the output shaft and the upper shaft head. Combined with the tapered roller bearing, which also allows a small radial deviation in the axial line of the upper shaft head, the combined effect of the two can offset the error of the low coaxiality of the output shaft, the upper shaft head, and the underwater support assembly, enabling the machine to operate smoothly.
