Description

Technical Field

[0001] This utility model relates to the field of pigment manufacturing equipment technology, specifically a mixing device for pigment manufacturing with quantitative addition function. Background Technology

[0002] In the pigment manufacturing process, multiple raw materials need to be mixed in specific proportions to obtain the desired color and properties. Existing pigment manufacturing mixing equipment typically uses manual estimation or simple metering devices to add raw materials, which presents the following problems:

[0003] Low metering accuracy: Manual operation is prone to deviations in the amount of raw materials added, affecting the consistency between batches of pigments;

[0004] Uneven mixing: Traditional stirring structures can only achieve mixing in one direction or region, which cannot fully disperse pigment particles;

[0005] Inconvenient to operate: The opening, closing, cleaning and unloading processes of the equipment are cumbersome, reducing production efficiency;

[0006] Maintenance difficulties: Key components lack protective structures and are susceptible to corrosion from pigment dust, which shortens their service life. Utility Model Content

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. In this utility model, the precise control of the amount of raw materials added is achieved by using a quantitative valve in conjunction with a measuring scale, thereby improving the consistency between batches of pigments. In addition, the double helix structure formed by the outer and inner stirring belts generates axial and radial convection under the drive of the stirring shaft, which significantly improves the uniformity of pigment mixing.

[0019] 2. In this utility model, the opening and closing of the top cover and the discharge baffle are assisted by the first hydraulic support rod and the second hydraulic support rod respectively, which reduces the intensity of manual operation and facilitates equipment cleaning and maintenance. In addition, the protective shell effectively isolates the drive motor and reducer from the contact with pigment dust, reduces equipment failure, and extends service life.
