Problems solved by technology

But the mixer of existing structure has the following problems: because the impeller has a certain distance from the bottom of the tank body, the stirring effect at the bottom of the tank is poor, which affects the physical or chemical process of the medium; when the tank body is very high, its drive shaft will also When the mixer is rotating, the winding degree of the drive shaft is large; when the chemical medium contains fibrous substances, the fibrous substances are easy to wrap around the blades, which affects the balance of the impeller; the movement mode of the mixed liquid is single
These problems have adverse effects on the mixing effect

Embodiment Construction

[0019] The following description is merely exemplary in nature and not intended to limit the disclosure, application or use. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

[0020] Such as figure 1 and figure 2 As shown, a stirring device according to an embodiment of the present invention includes a driving device 1, a transmission shaft 3 and a lantern-shaped impeller 4, one end of the transmission shaft 3 is connected to the driving device 1, and the other end of the transmission shaft 3 is connected to the impeller 4 .

[0021] In the stirring device of this embodiment, the impeller 4 is set in a lantern shape, so that when the impeller 4 rotates, flow is formed in the upper part and the lower part respectively, and convection is formed at the junction of the upper part and the lower part (that is, the parting surface of the impeller 4). In this way, it can be fully mixed and sti...

Abstract

The invention discloses a stirring device. The stirring device comprises a driving device, a transmission shaft and a lantern-shaped impeller, wherein one end of the transmission shaft is connected with the driving device, and the other end of the transmission shaft is connected with the impeller. The stirring device can fully mix and stir, and does not have stirring dead corners, so that the stirring effect is improved.

Description

technical field [0001] The invention belongs to the technical field of chemical machinery, and in particular relates to a stirring device. Background technique [0002] The mixer is widely used in the chemical process for mixing and mixing liquid-solid, liquid-liquid, liquid-vapor two-phase and solid-liquid-vapor three-phase media in various physical and chemical processes. Chemical processes have a big impact. The mixer is vertically installed in the tank, and usually includes a driving device, a frame, a transmission shaft and an impeller. The impeller rotates with the transmission shaft to perform work on the mixed liquid for stirring and mixing. But the mixer of existing structure has the following problems: because the impeller has a certain distance from the bottom of the tank body, the stirring effect at the bottom of the tank is poor, which affects the physical or chemical process of the medium; when the tank body is very high, its drive shaft will also When the mi...
