Embodiment Construction

[0021] The technical solutions of the present invention will be further described in detail below through the accompanying drawings and embodiments.

[0022] Device embodiment

[0023] figure 1 It is a schematic structural diagram of an embodiment of the circulating grinding and dispersing device of the present invention. like figure 1 As shown, the main structure of this embodiment is a grinding cylinder 4, a material circulation pipe 5 and a storage cylinder for storing materials. In this embodiment, the storage cylinder includes two outer cylinders, specifically a first outer cylinder 11 and a second outer cylinder 12 . The feed port of the grinding cylinder 4 is connected to the connection between the discharge port of the first outer cylinder 11 and the discharge port of the second outer cylinder 12, and is used to The material output from the drum 12 is ground and dispersed. The discharge port of the grinding drum 4 is connected to the connection between the feeding...

Abstract

The invention relates to a cycle grind dispersing device, which comprises a sand cylinder used for grind dispersing treatment of materials, storage cylinders used for storing materials and a material circulating tube communicating the sand cylinder and the storage cylinder. The invention is characterized in that the storage cylinders are at least two outer material cylinders respectively used for storing materials treated by the sand cylinder in different grind dispersing cycles; one end of each outer material cylinder is communicated with the material circulating tube and is provided with an inlet valve used for controlling the materials to enter; the other end is communicated with the sand cylinder and is provided with an outlet valve used for controlling the materials to flow out. The invention also relates to a cycle grind dispersing method, which ensures that all the materials stored in the outer material cylinders are fully grinded and evenly dispersed, while the materials after the grind dispersing treatment has small particle size, equal particle size without materials with large particle size and with narrow particle size distribution, thus remarkably improving the dispersing quality and efficiency of the materials and having the advantages of large material quantity of a single grind dispersing, high quality of grind dispersing, high efficiency and so on.

Description

technical field [0001] The invention relates to a circulating grinding and dispersing device and method, in particular to a circulating grinding and dispersing device and method for increasing the amount of dispersing materials in a single grinding, and can be used to modulate organic pigments for color filter pigment photoresists of liquid crystal displays. Background technique [0002] In the production of inks, coatings and pigment photoresists, the selected materials are usually ground and dispersed, so that the materials after grinding and dispersing can meet the particle size distribution requirements of the finished product. The particle size of the material after initial synthesis is relatively coarse, generally distributed in a wide particle size distribution range of 10-200 μm. Since the particle size of the material directly affects its color strength, transparency, heat resistance, light resistance and solvent resistance, the initially synthesized materials canno...
