Background

Stirring is a common process in industrial production or experiments, and a stirring rod is a stirring tool which is necessary for industrial production or experiments and cannot use stirring blades (the stirring blades have large stirring vibration), and the application range of the stirring tool is quite wide, such as: the reaction rate is accelerated through the mixed liquid in the stirring reaction kettle in a chemical laboratory, or the speed of heating and melting sugar particles into liquid syrup is improved through stirring in the food processing process, or raw materials of artificial stones are stirred and uniformly mixed in the artificial stone production process.

The existing stirring rod is actually a cylindrical rod made of corresponding materials, and axial rotation is realized through a power device in the stirring process so as to stir mixed liquid. The stirring rod forms the purpose that the shearing force realized the stirring through rotating to mixed liquid body, therefore the stirring rod rotates the size that forms the shearing force and determines the stirring effect, and the stirring rod rotates the shearing force to mixed liquid more promptly, and stirring effect is better in same churning time, otherwise, then stirring effect is not good enough. In the process of rotating the existing stirring rod, the shearing force is formed on the mixed liquid only through the side wall, and the side wall of the stirring rod is a smooth arc surface, so that the formed shearing force is small.

Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1 and 2, a stirring rod comprises a rod body 1 which is columnar and stirs a liquid mixture by axial rotation, and a stirring tank 2 for increasing shearing force to the liquid mixture during the stirring process of the rod body 1. The agitating tank 2 is formed by arranging a plurality of layers of agitating tanks 2 on the side wall of the stick body 1 up and down along the axial direction of the stick body 1, and each layer of agitating tank 2 has a plurality of agitating tanks 2.

The opening of the stirring groove 2 faces the outer side of the stick body 1, and the two side surfaces of the stirring groove are a first side surface 3 and a second side surface 4 respectively in the front and at the back of the stick body 1 in the rotating direction. One end of the first side surface 3 is located at a corresponding position in the stick body 1, and the other end is deflected by an angle α in a direction opposite to the direction of rotation of the stick body 1 and toward the outside of the stick body 1. One end of the second side surface 4 is located at a corresponding position in the stick body 1, and the other end is deflected by an angle θ toward the outside of the stick body 1 and toward the rotation direction of the stick body 1.

When α > θ: as shown in fig. 3, the roller 1 is driven by the power unit to rotate, and during the rotation, the first side 3 forms a stirring shear force to the mixed liquid in the stirring tank 2 in addition to the stirring shear force to the mixed liquid formed by the side wall of the roller 1: since α > θ, the shearing force applied to the mixed liquid body by the end (L) of the first side surface 3 close to the outside of the stick body 1 is not affected by the second side surface 4 (the straight arrow in fig. 3), that is, the end of the first side surface 3 close to the outside of the stick body 1 stirs the mixed liquid body.

When α is θ, that is, the first side surface 3 and the second side surface 4 are arranged in parallel (as shown in fig. 4), the shearing force formed by the end of the first side surface 3 close to the outer side of the stick body 1 to the mixed liquid is affected by the second side surface 4, and the second side surface 4 blocks the stirring of the mixed liquid by the first side surface 3, so that the purpose of improving the stirring efficiency cannot be achieved.

When alpha < theta (as shown in FIG. 5), the portion L of the first side surface 3 that can stir the mixed liquid is located at the end portion of the stick body 1 near the outside thereof₁，L₁L, and therefore the final stirring effect α > θ is inferior to that when α > θ.

The shearing force formed on the mixed liquid body is influenced by the second side surface 4, and the second side surface 4 can block the stirring of the mixed liquid body by the first side surface 3, so that the purpose of improving the stirring efficiency cannot be achieved. In addition, since the first side surface 3 has a straight surface structure, a larger shearing force is generated to the mixed liquid than the arc-shaped side surface of the stick body 1.

The central line of the included angle formed by the first side surface 3 and the second side surface 4 does not pass through the center of the bottom surface of the stick body 1, so that each layer of the stirring groove 2 is in a spiral shape consistent with the rotation direction of the stick body. Because the same layer of stirring tank 2 is spiral, the mixed liquid in the same layer of stirring tank is thrown farther away under the action of centrifugal force, so that the liquid at the farther position of the rod body 1 is stirred, and finally, the stirring efficiency is further improved. The two adjacent layers of the stirring grooves 2 are arranged in a staggered manner in the axial direction of the rod body 1, so that the rod body 1 has the functions of the stirring grooves 2 in different radial directions, and the effect of stronger shearing force on the mixed liquid in the axial direction of the rod body 1 is realized.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
