Description

Technical Field

[0001] The utility model belongs to the technical field of dispersion equipment, in particular to vacuum dispersion equipment. Background Art

[0002] In the fields of coatings, dyes, inks, pigments, cosmetics, resins, adhesives, emulsions, medicines, petroleum, etc., dispersion devices are generally used to stir, dissolve and disperse materials at high speed. Dispersion devices include vacuum dispersion. Dispersion in a vacuum state can accelerate the dispersion fineness of the material, quickly degas the material, and thus improve the dispersion effect of the material.

[0003] At present, the stirring mechanism inside the vacuum dispersion device is too simple and can usually only stir within a certain range. There are dead corners in the dispersion box, which leads to incomplete dispersion. In addition, when the raw materials are poured into the dispersion box, the heavier raw materials are easy to deposit at the bottom of the dispersion box, making it impossible to disperse and mix quickly, resulting in a lot of time for dispersion, which in turn increases the dispersion cost. Utility Model Content

[0004] The utility model provides vacuum dispersing equipment, aiming to solve the problems of dead stirring angles in current dispersing equipment and poor dispersing effect caused by easy sedimentation of raw materials.

Two groups of connecting plates 7 are symmetrically fixed on the side of the connecting sleeve 6. The surfaces of the two groups of connecting plates 7 are provided with grooves that are compatible with the diameter of the fixed rod 4. The connecting plates 7 are slidably connected to the fixed rod 4. A stirring blade 8 is fixed at the far end of the two groups of connecting plates 7. The dispersion box 1 is supported and fixed by a support frame 9. A motor 10 is installed on the upper surface of the support frame 9. The output shaft of the motor 10 is transmission-connected to the rotating shaft 3 through a belt 11. A material port 12 is provided on the outer wall of the dispersion box 1, and the material A valve is provided at the opening 12, a vacuum pump 20 is installed on the top of the support frame 9, a connecting pipe 21 is connected to the lower side of the vacuum pump 20, the connecting pipe 21 is a plastic hose, and a matching connector is provided between the connecting pipe 21 and the material opening 12. When the device is used, the raw materials can be poured into the dispersion box 1 from the material opening 12, and then the valve at the material opening 12 is closed, and then the motor 10 is started. The motor 10 drives the rotating shaft 3 to rotate through the belt 11, and the rotating shaft 3 drives the connecting plate 7 and the connecting sleeve 6 to rotate as a whole through two sets of fixed rods 4. The connecting sleeve 6 slides horizontally under the action of the thread of the screw 5, so that the stirring blade 8 is located in the dispersion box 1 and moves for stirring. Through this arrangement, the stirring range of the stirring blade 8 can be increased, the stirring can be made more thorough, and the problem of poor dispersion effect due to stirring dead corners can be avoided.

[0020] The support frame 9 is arranged in a ring shape and has a ball embedded inside. The dispersion box 1 is rotationally connected to the support frame 9. A gear 13 is fixed to the outside of the output shaft of the motor 10. A gear ring 14 is installed on the outer wall of the dispersion box 1. The gear 13 and the gear ring 14 are meshed with each other. By providing the gear 13 and the gear ring 14, the motor 10 drives the dispersion box 1 to rotate as a whole through the transmission of the gear 13 and the gear ring 14.
