[0002] A vacuum mixer is a device that integrates stirring and vacuum degassing. It is mainly used for mixing and stirring high-viscosity liquids and granular liquids. However, most vacuum mixers in the prior art tend to focus on stirring and mixing without considering the actual particle size of the materials. During the stirring and mixing process, the particles are easily settled under the action of the stirring centrifugal force and gravity, resulting in uneven distribution of the mixed liquid particles and poor stirring effect. Summary of the invention

[0003] In order to solve the problems existing in the prior art, the present invention provides a vacuum mixer which can prevent particles from settling.

The strong magnetic rings are sleeved on the outer periphery of the mixing drum and movably cooperate with the mixing drum. Iron blocks are fixedly installed on the outer ends of the mixing blades. The strong magnetic rings attract the iron blocks on the inner side of the mixing drum. The vertical movement of the strong magnetic rings is adjusted by installing the adjustment assembly to adjust the angle of the mixing blades.

[0007] Furthermore, the installation and adjustment component includes an electric telescopic rod, at least four electric telescopic rods are hingedly installed below the strong magnetic ring on the lower side, the fixed ends of the electric telescopic rods are installed above the base, and vertical connecting rods corresponding to the electric telescopic rods are provided between adjacent strong magnetic rings. Both ends of the connecting rods are hingedly connected to the strong magnetic rings on the corresponding sides, and the strong magnetic ring located at the upper end is installed on the upper periphery of the mixing drum through springs corresponding to the electric telescopic rods.

[0008] Furthermore, the angle limiting components include four limit columns, which are installed on the outside of the spherical mounting seat. The four limit columns on the outside of each spherical mounting seat are distributed at the four corners of an inverted isosceles trapezoid and are staggered between the two limit columns located on the upper and lower sides of the spherical mounting seat.

[0009] Furthermore, the connecting rod adopts an electric push rod structure, and the height between two adjacent strong magnetic rings is adjusted by the electric push rod type connecting rod.

[0010] Furthermore, the lower end of the vertical shaft passes through the lower end of the mixing drum and is rotatably connected thereto, a sealing assembly is installed on the outer side of the lower end of the vertical shaft to ensure sealing, a vertical groove is provided on the top surface of the base, a motor is installed in the groove, the output shaft of the motor is fixedly connected to the lower end of the vertical shaft, the vertical shaft is driven to rotate by the motor, a vacuum assembly is installed on the outer side of the mixing drum cover, the vacuum assembly is connected to the inside of the mixing drum, and the vacuum assembly vacuums the inside of the mixing drum.

[0011] The beneficial effects achieved by the present invention are as follows: the present invention installs the stirring blades through a spherical mounting seat, and each group of stirring blades is deflected along the corresponding spherical mounting seat under the action of its corresponding strong magnetic ring, so that the stirring blades can flip the materials in the mixing drum along the up and down directions and the inside and outside directions of the mixing drum during the rotational stirring, thereby improving the overall stirring effect and effectively preventing the sedimentation of the particulate material; and the present invention deflects each group of stirring blades at different angles by adjusting the different extension lengths of four electric telescopic rods, so that materials at different heights can be stirred by the same group of stirring blades, and multi-level stirring of the materials in the mixing drum can be achieved through the stirring of multiple groups of stirring blades, thereby further improving the stirring effect.

The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0020] like Figures 1 to 4As shown, the present invention provides a vacuum mixer for preventing particle sedimentation, comprising a base 1, a cylindrical mixing drum 2 is installed above the base 1, a vertical mixing shaft 3 is arranged in the mixing drum 2, and a group of mixing blades 4 are arranged on the outside of the mixing shaft 3 along the length thereof, each group of mixing blades 4 includes a number of mixing blades 4 evenly distributed along the circumferential direction, each mixing blade 4 is spherically installed on the outside of the mixing shaft 3 through a spherical mounting seat 5, and a torsion spring is installed at the mounting position of the mixing blade 4 to facilitate the mixing blade 4 to maintain a horizontal state, so that the mixing blade 4 is installed by the spherical mounting seat 5 so that the mixing blade 4 can be relatively moved under the action of an external force The stirring shaft 3 is deflected at multiple angles to adjust the stirring angle of the stirring blade 4, making the stirring angle of the stirring blade 4 diversified. When the stirring shaft 3 rotates, the stirring blade 4 can rotate and stir the material inside the stirring drum 2. As the angle of the stirring blade 4 changes, the material can be stirred in multiple dimensions in the inside and outside directions and in the up and down directions of the stirring drum 2. Of course, an adjustment component for adjusting the angle of the stirring blade 4 is provided on the outside of the stirring drum 2, and an angle limiting component is provided on the outside of the spherical mounting seat 5 to limit the deflection angle of the stirring blade 4.

[0021] like Figure 1 , 2 As shown, one implementation of the angle adjustment component is that the outer side of the mixing drum 2 is installed with strong magnetic rings 10 with the same number as the mixing blades 4 through the installation of the adjustment component. The strong magnetic rings 10 are sleeved on the outer periphery of the mixing drum 2 and movably cooperate with it. The outer ends of the mixing blades 4 are fixedly installed with iron blocks 6. In this way, the strong magnetic rings 10 attract the iron blocks 6 on the inner side of the mixing drum 2, and the vertical movement of the strong magnetic rings 10 is adjusted by installing the adjustment component, thereby driving the mixing blades 4 to deflect in the upward and downward directions along the spherical mounting seat 5, thereby adjusting the stirring angle of the mixing blades 4.

[0022] like Figure 2 As shown in , in order to make the deflection angle of the stirring blade 4 more multi-dimensional, an implementation method of installing the adjustment component is that at least four electric telescopic rods 7 are hingedly installed below the strong magnetic ring 10 located at the lowermost side, and the fixed end of the electric telescopic rod 7 is installed above the base 1. At the same time, vertical connecting rods 8 corresponding to the electric telescopic rods 7 are provided between adjacent strong magnetic rings 10. The two ends of the connecting rods 8 are hingedly connected to the strong magnetic rings 10 on the corresponding side. At the same time, the strong magnetic ring 10 located at the uppermost end is installed on the upper periphery of the stirring drum 2 through springs 9 corresponding to the electric telescopic rods 7. In this way, the strong magnetic ring 10 can be installed so that the strong magnetic ring 10 is located on the outer side of the stirring blade 4 of the corresponding group in the initial state, and then the electric telescopic rod 7 is vertically extended and retracted, so that the strong magnetic ring 10 is moved vertically as a whole, so that the stirring blade 4 is vertically deflected along the spherical mounting seat 5. At the same time, the strong magnetic ring 10 can be made to be as follows through the different elongation lengths of the electric telescopic rod 7. Figure 4As shown in the figure, the deflection angles of the stirring blades 4 in the same group are different, so that each group of stirring blades 4 can perform multi-level and multi-angle stirring on the outer side of the material, ensuring the stirring effect, while effectively preventing the sedimentation of materials of different particle sizes under the action of centrifugal force.

[0023] like Figure 1 , 2 As shown, in order to limit the deflection angle of the stirring blade 4, preferably, the angle limiting components include four limit columns 11, and the limit columns 11 are installed on the outside of the spherical mounting seat 5, and the four limit columns 11 on the outside of each spherical mounting seat 5 are distributed at the four corners of an inverted isosceles trapezoid, so that the two limit columns 11 on the upper and lower sides of the spherical mounting seat 5 are staggered, so that when the stirring blade 4 deflects up and down along the spherical mounting seat 5, the two limit columns 11 on the upper and lower sides make the stirring blade 4 have a certain inclination angle, so that when the stirring blade 4 stirs the material inside the mixing drum 2, the material is turned over along the upper and lower directions of the mixing drum 2 to prevent the material from settling vertically.

[0024] More preferably, the connecting rod 8 also adopts an electric push rod structure, so that the height between adjacent strong magnetic rings 5 ​​can be adjusted, making the angle adjustment of the stirring blade 4 more diversified.

[0025] like Figure 1 , 2 As shown, the lower end of the vertical shaft 3 passes through the lower end of the mixing drum 2 and is rotatably connected thereto, and a sealing assembly is installed on the outer side of the lower end of the vertical shaft 3 to ensure sealing. At the same time, a vertical groove 13 is provided on the top surface of the base 1, and a motor 14 is installed in the groove 13. The output shaft of the motor 14 is fixedly connected to the lower end of the vertical shaft 3, and the vertical shaft 3 is driven to rotate by the motor 14. At the same time, a vacuum assembly 15 is installed on the outer side of the cover of the mixing drum 2, and the vacuum assembly 15 is connected to the inside of the mixing drum 2. In this way, the vacuum assembly 15 can vacuum the inside of the mixing drum 2, so that the inside of the mixing drum 2 can maintain a vacuum state during the process of the motor 14 driving the vertical shaft 3 to rotate. A discharging assembly is provided at the lower part of the mixing drum 2, and the discharging assembly belongs to a mature prior art and will not be described here.

[0026] Working principle: In the initial state, the cover of the mixing drum 2 is opened, and the material to be mixed is placed in the mixing drum 2, and then the cover seals the upper end of the mixing drum 2. All the mixing blades 4 are kept in a horizontal state outside the spherical mounting seat 5 under the action of the torsion spring, and all the strong magnetic rings 5 ​​are located outside the mixing blades 4 of the corresponding group and are in a horizontal state. Then, the mixing drum 2 is vacuumed by the vacuum assembly 15, and the motor 14 drives the vertical shaft 3 to rotate, thereby driving the mixing blades 4 to rotate accordingly. The strong magnetic ring 5 is moved by the extension of the electric telescopic rod 7, and the movement of the strong magnetic ring 5 attracts the iron block 6 to move accordingly, thereby causing the mixing blade 4 to deflect. The angle-deflected mixing blade 4 stirs the material inside the mixing drum 2, and due to the deflection of the mixing blade 4, the material is stirred and moved along the vertical direction of the mixing drum 2 and the inner and outer directions, thereby preventing the material from settling during the multi-angle stirring of the material. The above-described embodiments of the present invention do not constitute a limitation on the scope of protection of the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the claims of the present invention.
