Dispersion machine for producing environment-friendly low-carbon paint

Abstract

The invention discloses a dispersion machine for producing environment-friendly low-carbon paint in the field of paint and pigment stirring equipment. The dispersion machine comprises a machine frame, a suspension frame is arranged on the machine frame and provided with a guide column, a movable frame is arranged above the suspension frame, the guide column is movably sleeved with the movable frame, and a lifting device is arranged on the movable frame. A main shaft is movably supported on the movable frame, a dispersion plate is arranged at the lower end of the main shaft, and the movable frame is provided with a main driving device used for driving the main shaft to rotate. A rotary shaft is movably supported in the suspension frame, the main shaft is sleeved with the rotary shaft, the rotary shaft can independently rotate relative to the main shaft, the suspension frame is provided with a second driving device used for driving the rotary shaft to rotate, and an arc-shaped scraper is arranged below the suspension frame and fixed to the rotary shaft through a support. When a barrel used for fixing raw materials is placed below the suspension frame and the main shaft is located in the center of the barrel, the arc-shaped scraper can be attached to the inner wall of the barrel. The dispersion machine has the advantages of being good in stirring and dispersing effect, high in work efficiency and the like.

Description

technical field [0001] The invention relates to the field of paint and pigment stirring equipment, in particular to a disperser. Background technique [0002] Disperser is a high-efficiency equipment capable of stirring, dispersing, emulsifying and mixing slurry materials with different viscosities. It is widely used in the production and preparation of paints and pigments. Such as figure 1 As shown, the structure of a dispersing machine commonly used in the industry at present includes: a frame 101, a suspension beam frame 102 is arranged on the top of the frame 101, a main shaft 103 is movably supported in the suspension beam frame 102, and the lower end of the main shaft 103 protrudes vertically downward from the suspension beam The frame 102 and the lower end of the main shaft 103 are provided with a dispersing disc 104 . On the suspension beam frame 102, a drive motor 105 is also fixedly installed. The output shaft of the drive motor 105 is connected with the upper en...

AI Technical Summary

Problems solved by technology

[0003] The dispersion machine of above-mentioned structure has following shortcoming when working: one, because dispersion disc 104 is closer to the bottom position of bucket 107 buckets, and the height position of dispersion disc 104 remains unchanged from beginning to end, although be in the slurry form of bucket 107 lower floors like this The raw materials have a better stirring and dispersing effect, but they cannot stir and disperse the raw materials in the middle and upper layers of the material tank 107 well, especially for those materials that are added into the material tank 107 according to the needs of the production process. The stirring effect is weak, which will lead to some raw materials not being fully stirred, dispersed and dissolved, and piled up in the middle and upper positions of the material tank 107, which will eventually affect the product quality; The shear force generated by the disk 104 gradually spreads to the peripheral area of ​​the material tank 107, causing a part of the slurry material that has not been completely dissolved to adhere to the inner wall of the material tank 107, and cannot be further stirred and dispersed, which will lead to the stirring and dispersing effect of the disperser. poor

Therefore in the work, it is often necessary for the operator to stand on the edge of the mouth of the bucket 107 with a stirring rod in hand, and constantly scrape off the raw materials adhered to the inner wall of the bucket 107. Not only is the operation very cumbersome, but the work efficiency is low; Risk of personnel accidentally falling into barrel 107
