specific Embodiment 1

[0019] Such as figure 1 As shown, it is a structural schematic diagram of a specific embodiment 1 of the present invention, including: a vacuum stirring tank 1, the upper part of the vacuum stirring tank is provided with a pigment base material inlet 11, an auxiliary agent inlet 12 and a vacuum exhaust port 14, and the bottom is provided with Material outlet 13; the vacuum stirring tank is provided with a stirring shaft 2 connected to an external drive device, and an angle α is formed between the stirring shaft and the axis passing through the pigment base material inlet 11; the stirring shaft is provided with multiple A stirring part 21, this stirring part is made up of a plurality of stirring blades uniformly surrounding the stirring shaft, the shape of the blades is as figure 1 As shown, other blades that are conducive to stirring can also be used, and through holes can be opened on the surface of the stirring blade; and a plurality of stirring parts are equidistantly arran...

specific Embodiment 2

[0020] Such as figure 2 Shown is a schematic structural view of a specific embodiment 2 of the present invention. The difference between this embodiment and the above-mentioned embodiment is that the stirring blades of the stirring parts 22 and 23 located at both ends of the stirring shaft are helically distributed along the stirring shaft. The direction of the helical distribution of the blades of the stirring parts 22 and 23 is opposite, so that during the stirring process of the pigment slurry, the slurry in the stirring tank is pushed to the middle of the stirring shaft, so that the stirring is more uniform and the stirring is further improved. efficiency.

specific Embodiment 3

[0021] Such as image 3 As shown, it is a structural schematic diagram of a specific embodiment 3 of the present invention. The difference between this embodiment and embodiment 1 is that an auxiliary stirring shaft 3 is also provided at the bottom of the vacuum stirring tank 1, and the auxiliary stirring shaft is located at the bottom of the vacuum stirring tank 1. One end of the outside of the vacuum stirring tank is used to connect the driving device; the auxiliary stirring shaft 3 has an included angle less than 90 degrees and greater than 0 degrees between the axis passing through the inlet of the pigment base material, and the auxiliary stirring shaft 3 A plurality of stirring blades are provided surrounding the auxiliary stirring shaft. In order to prevent the stirring shaft 2 from forming a dead zone in the lower corner of the tank during operation, an auxiliary stirring shaft 3 is added here, and the blades of the stirring shaft are twisted to ensure that the material...

Abstract

The invention relates to a pigment paste twisting device that comprises the vacuum twisting can whose top has pigment base inlet, auxiliary agent inlet and vacuum exhaust, bottom with material outlet, inside the vacuum twisting can having twisting shaft connected with the outside drive device, which having a first included angle with the material inlet shaft line, the said twisting shaft having several twisting part which is made of several twisting blades surrounded the shaft. It not only reduces the contamination in the process of pigment twisting, but also realizes even twisting with improved efficiency and quality and reduced energy consumption.

Description

technical field [0001] The invention relates to a stirring device, in particular to a vacuum stirring device for stirring a photoresist pigment slurry for a color filter. Background technique [0002] For the production of pigment photoresists, stirring is an essential production link. The pigment slurry used for color filters is a kind of pigment slurry that has high requirements on the production environment and production process, which directly affects the color The photoresistive properties of the filter; therefore, in the process of stirring, it is necessary to avoid the pollution of various impurities, and the cleanliness of the stirring environment is high; and the components of the pigment slurry are required to be evenly mixed, and there is no Bubbles exist, which requires vacuum uniform stirring during the stirring process. [0003] Existing mixing equipment has low requirements for vacuum degree, most of them are non-airtight and cannot achieve a high degree of ...
