Problems solved by technology

[0004] At present, the common stirring paddle is a consumable part in the stirring device that is easily damaged and worn due to its low mechanical strength and the blade is easily damaged.
Most of the stirring heads use couplings or flanges to connect the stirring paddle and the stirring shaft on the hub, and using this connection method, two flanges on the hub and the stirring shaft are required in the process of installing the stirring paddle Or the screw holes on the coupling can be installed correctly only if all the screw holes are aligned. If the screw holes are not aligned or the connection angle is wrong, it will affect the installation process and installation effect
Therefore, the installation process of the mixing head using this connection method is extremely inconvenient, and the requirements for the operating proficiency of the installers are also relatively high.
On the other hand, if there is a deviation during the installation or replacement of the stirring paddle, it will easily affect the operation stability of the entire stirring device, and at the same time cause abnormal wear and tear on the flanges, couplings and other components used for fixing in the stirring device. loss, increased cost
And because the unstable operation of the stirring device will also affect the mixing effect between the medium phases, if the expected mixing effect cannot be achieved, it will affect the further operation, and even require rework

Embodiment 1

[0024] Such as figure 1 and figure 2 The shown agitating head includes a stirring shaft 1, a stirring paddle 2, and the stirring paddle 2 includes a hub 3 and paddles 4 arranged on the hub 3, and the hub 3 is sleeved on the stirring shaft 1, wherein, The outer periphery of the stirring shaft 1 is provided with a groove 11 , the hub 3 is provided with a fixing part 5 , and the positioning end 51 of the fixing part 5 is matched with the groove 11 . The groove 11 is used in cooperation with the fixing part 5, and it cannot be installed when the angle between the fixing part 5 and the groove 11 is wrong, which avoids damage to the flange or coupling caused by the wrong angle during the installation process. On the other hand, since there is no screw connection between the provided groove 11 and the fixing member 5, the need for tools in the installation process is avoided, and the installation and replacement of the stirring paddle is convenient.

[0025] Further, the outer per...

Embodiment 2

[0029] Such as image 3 and Figure 4 The difference between the agitating head shown in Embodiment 1 is that the fixing member 5 is provided with a locking groove 52, the hub 3 is provided with an elastic buckle 32, and the locking groove 52 and the locking groove 52 are The elastic buckle 32 is engaged with each other. This setting can make the fixing effect of the fixing part 5 more stable, and only when a sufficiently large axially outward pulling force is applied on the fixing part 5, the fixing part 5 will come out of the through hole 31 and the groove 11, avoiding the operation process. The loosening of the middle fixing part 5 and the hub 3.

[0030] A stirring device, comprising a motor, a reducer and a stirring head, the motor drives the stirring head to rotate through the reducer, characterized in that the stirring head is any one of the stirring heads described in Embodiment 1 or 2 above.

Abstract

The invention relates to a stirring head which comprises a stirring shaft and a stirring paddle. The stirring paddle comprises a hub and a blade; the blade is arranged on the hub; the hub is sleeved on the stirring shaft; the periphery of the stirring shaft is provided with a groove; the hub is provided with a fixing component; and the fixing end of the fixing component matches with the groove. The invention also relates to a stirring device which comprises a motor, a speed reducer and a stirring head; the motor is used for driving the stirring head to rotate through the speed reducer; and the stirring head is the stirring head provided by the invention. The stirring head and the stirring device with the stirring head are simple in structure, and the paddle can be installed and changed conveniently.

Description

technical field [0001] The invention relates to a stirring paddle, in particular to a conveniently installed stirring head. [0002] The invention also relates to a stirring device, in particular to a stirring device which is convenient for installing a stirring head. Background technique [0003] The constant stirring device is a kind of equipment that makes the liquid and gas medium forced convection and makes them evenly mixed, and can strengthen the heat transfer and mass transfer between the phases. The stirring device is mainly composed of three parts: the stirrer, the transmission device and the stirring shaft system. The agitator is mainly composed of stirring paddles or impellers and auxiliary components. The transmission device is mainly composed of motors, reducers, brackets, etc. The stirring shaft system is mainly composed of stirring shafts, bearings, couplings, etc. [0004] At present, the common stirring paddle is a consumable part in the stirring device t...
