Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
Example 1
As shown in fig. 1, a stirring blade for a center stirring device includes a hub 1 and blade assemblies located on both sides of the hub 1, the blade assemblies including a first flat plate portion 2 adjacent to the hub 1 and a twisted portion 3 connected to the first flat plate portion 2. The hub 1 is used for being connected with a stirring shaft in the central stirring equipment, the stirring shaft is positioned at the central position of the central stirring equipment, and the stirring shaft is connected with corresponding driving equipment such as a motor and the like, so that the stirring shaft drives the stirring blade to stir at the central position of the stirring equipment. When the stirring shaft rotates anticlockwise according to the driving direction, the first flat plate part 2 can drive the corresponding raw material liquid to flow upwards, and the twisting part 3 can drive the corresponding raw material liquid to flow downwards.
Referring to fig. 1 and 2, the first flat plate portion 2 has a flat plate structure, and the first flat plate portion 2 is provided with two sides respectively connected to two sides of the hub 1, wherein one side overlaps with the other side after rotating 180 ° along the hub 1. As shown in fig. 2, the first plate portions 2 include an upper flat top end 4 and a lower flat bottom end 5, and a connecting line between the upper flat top end 4 and the lower flat bottom end 5 is obliquely arranged with a central axis of the hub 1 portion, as shown by an arrow K1 in fig. 1, when the hub 1 rotates counterclockwise, two first plate portions 2 are driven to rotate counterclockwise, and the first plate portions 2 drive a raw material liquid portion in a corresponding area to flow outwards and a portion to flow upwards. The twisting part 3 connected with the outer side of the first flat plate part 2 is of a twisted plate-shaped structure, the twisting part 3 comprises an upper twisting top end 6 and a lower twisting bottom end 7, a connecting line between the upper twisting top end 6 and the lower twisting bottom end 7 and a connecting line between the upper leveling top end 4 and the lower leveling bottom end 5 are arranged in a crossed mode, as shown in fig. 3, a certain included angle a is formed between the outer side edge of the first flat plate part 2 and the outer side edge of the twisting part 3, the included angle a ranges from 45 degrees to 90 degrees, when the hub 1 rotates anticlockwise, the twisting part 3 is driven to rotate anticlockwise, and the twisting part 3 drives a raw material liquid part in a corresponding area to flow outwards and to flow downwards as shown by an arrow K2 in fig. 1. At this time, the material liquid in the stirring area of the first flat plate portion 2 and the material liquid in the stirring area of the twisted portion 3 generate a certain convection, and the material liquid in the stirring area of the first flat plate portion 2 and the material liquid in the stirring area of the twisted portion 3 are sufficiently collided and mixed, so that a better mixing effect can be generated. And the convection current that produces in this scheme is bigger, compares traditional technique, and the mixing effect is better.
