Description

Technical Field

[0001] The utility model relates to the technical field of stirrers, in particular to a stirring structure with a rotatable stirring arm. Background Art

[0002] The agitator arm is a key component in mixing equipment, used to mix, stir, or disperse materials within a container or reactor. Typically, most agitator arms are fixedly connected to the agitator shaft via threads, keys, or pins. However, this fixed connection can affect the mixing efficiency of the agitator. For example, depending on the viscosity, density, or particle size of the material, the mixing objectives (e.g., uniform mixing, dispersion, emulsification, dissolution), and process conditions (e.g., temperature, pressure, stirring speed), the angle of the agitator arm must be adjusted to optimize the mixing effect.

[0003] Therefore, in order to solve the defect that the fixed connection of the stirring arm leads to a decrease in mixing efficiency, it is necessary to propose a stirring structure with a rotatable stirring arm. Utility Model Content

[0004] The purpose of the present invention is to provide a stirring structure with a rotatable stirring arm. By designing a rotatable stirring arm, the angle of the stirring arm can be flexibly adjusted according to different material properties, mixing objectives and process conditions, thereby optimizing the mixing effect and solving the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A stirring structure with a rotatable stirring arm, comprising a stirring shaft, a stirring arm and a stirring blade, wherein the stirring arms are symmetrically arranged about the stirring shaft, and each two stirring arms form a group, and multiple groups of stirring arms are equidistantly installed on the stirring shaft;

[0007] The stirring arm includes a hoop plate and a cylinder welded to the hoop plate, a first flange is installed at one end of the cylinder, a rotating shaft is movably installed in the cylinder, a second flange is installed at one end of the rotating shaft outside the cylinder for use with the first flange, an arm body is welded to the outside of the second flange, and a stirring blade is detachably installed at the front end of the arm body.

[0008] Preferably, wing plates are symmetrically welded to both ends of the hoop plate, and a fixing plate assembled and connected to the wing plates is welded to the stirring shaft, and the wing plates and the fixing plates are fixed to each other by bolts.

[0009] Preferably, the first flange and the second flange are correspondingly provided with adjustment holes, and the first flange and the second flange are fixed to each other through bolts and the adjustment holes.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. The stirring structure of this stirring arm can be rotatable. By designing a rotatable stirring arm, the angle of the stirring arm can be flexibly adjusted according to different material properties, mixing goals and process conditions, thereby achieving a more precise and efficient mixing effect.

DETAILED DESCRIPTION

[0021] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] In order to solve the technical problem of how to assemble the stirring arm and the stirring shaft, please refer to Figure 1-Figure 2 The embodiment provides the following technical scheme:

[0023] A stirring structure with rotatable stirring arms comprises a stirring shaft 1, stirring arms 2 and stirring blades 3. The stirring arms 2 are symmetrically arranged about the stirring shaft 1, and every two stirring arms 2 form a group. A plurality of groups of stirring arms 2 are equidistantly installed on the stirring shaft 1.

[0024] The symmetrically arranged stirring arms 2 help to maintain the balance of the stirring shaft 1, reduce vibration and unbalanced force during high-speed rotation, and the plurality of groups of stirring arms 2 are arranged to increase the stirring area and ensure that the material can be subjected to uniform shearing force and stirring force during the stirring process.

[0025] The stirring arm 2 comprises a hoop plate 21, wing plates 211 are symmetrically welded at both ends of the hoop plate 21, a fixing plate 11 is welded on the stirring shaft 1 and connected with the wing plates 211, and the wing plates 211 and the fixing plate 11 are fixed by bolts.

[0026] Specifically, when the stirring arm 2 needs to be assembled, the two hoop plates 21 are attached to the left and right ends of the stirring shaft 1, the wing plates 211 of the two hoop plates 21 are aligned with the same fixing plate 11, the screw rod is passed through the corresponding assembly holes of the wing plates 211 and the fixing plate 11, and finally the nuts are screwed on both ends of the screw rod to fixedly connect the two hoop plates 21 to the fixing plate 11, thereby realizing the assembly of the stirring arm 2 and the stirring shaft 1.

[0027] In order to solve the technical problem of how to rotate the stirring arm, please refer to Figure 3 The embodiment provides the following technical scheme:

[0028] A cylinder 22 is welded on the hoop plate 21, a first flange plate 23 is installed at one end of the cylinder 22, a rotating shaft 24 is movably installed in the cylinder 22, a second flange plate 25 is installed at one end of the rotating shaft 24 outside the cylinder 22 and used in cooperation with the first flange plate 23, and an arm body 26 is welded outside the second flange plate 25.

[0029] Adjusting holes 27 are formed in the first flange plate 23 and the second flange plate 25, and the first flange plate 23 and the second flange plate 25 are fixed by bolts and the adjusting holes 27.

[0030] Specifically, when the angle of the stirring arm 2 needs to be adjusted, the bolts on the first flange 23 and the second flange 25 are removed. Since the rotating shaft 24 is movably installed with the cylinder 22, and the rotating shaft 24 is fixedly connected to the arm body 26 through the second flange 25, the rotating shaft 24 can drive the arm body 26 to rotate until the arm body 26 rotates to the desired angle and makes the adjustment holes 27 on the first flange 23 and the second flange 25 correspond. Finally, the first flange 23 and the second flange 25 are fixed with bolts.

[0031] To solve the technical problem of how to assemble the stirring blade and stirring arm, please refer to Figure 4 , this embodiment provides the following technical solutions:

[0032] A cross slot 261 is provided at the front end of the arm body 26, and a bracket plate 262 is welded outside the cross slot 261. A reinforcement plate 31 is welded to the blade surface of the stirring blade 3. The reinforcement plate 31 and the stirring blade 3 form a cross shape and are engaged with the cross slot 261. The stirring blade 3 and the reinforcement plate 31 are fixed to the bracket plate 262 by bolts.

[0033] Specifically, align the blade body and the reinforcing plate 31 of the stirring blade 3 with the cross groove 261 and insert them. At this time, the blade body and the reinforcing plate 31 are engaged with the cross groove 261, and then the reinforcing plate 31 and the blade are fixed to the bracket plate 262 with bolts.

[0034] Working principle: This stirring arm has a rotatable stirring structure. When the angle of the stirring arm 2 needs to be adjusted, the bolts on the first flange 23 and the second flange 25 are removed. Since the rotating shaft 24 is movably installed with the cylinder 22, and the rotating shaft 24 is fixedly connected to the arm body 26 through the second flange 25, the rotating shaft 24 can drive the arm body 26 to rotate, and then rotate the arm body 26 until the arm body 26 is rotated to the required angle, and the adjustment holes 27 on the first flange 23 and the second flange 25 correspond to each other. Finally, the first flange 23 and the second flange 25 are fixed with bolts to achieve the adjustment of the angle of the stirring arm 2.
