Problems solved by technology

[0004] However, the existing liquid grinding and refining equipment is too simple to continuously complete ultra-fine grinding, fractionation, mixing and refining of modifiers, and cannot achieve liquid phase stability in which the blends accommodate each other and disperse state
[0005] At the same time, the existing equipment and processes for homogenizing the mother liquor of modified aromatics and aromatics are too simple and cannot continuously meet the technical requirements for the preparation of multifunctional modified aromatics. After homogenization, the materials in the product cannot accommodate each other and cannot be dispersed. uniform

Embodiment 1

[0053] The invention relates to a manufacturing equipment of multifunctional modified aromatics, which includes a refining unit and a homogenizing unit.

[0054] Among them, such as figure 1 As shown, the refinery device includes a laterally arranged cylindrical refinery cylinder 100 and a stirring mechanism.

[0055] The refinery cylinder is divided into five refinery chambers 102 by partitions 101 in the axial direction, and the five refinery chambers are sequentially denoted as refinery chambers I to V according to the material flow direction, and the top of the refinery chamber I is respectively A feed port 103 is provided, and a discharge port 104 is provided on the top of refining chamber V. Adjacent refining chambers are connected by pipelines, and two parallel column filters 105 are arranged on the pipelines; Such as Figure 4 As shown, the cross-section of the filter net is toothed and annular. The mesh of the filter screen decreases in order according to the dire...

Embodiment 2

[0063] A method for preparing multifunctional modified aromatic hydrocarbons, using the manufacturing equipment of Example 1, first preparing the multifunctional modified aromatic hydrocarbon mother liquor from aromatic hydrocarbons containing modifiers through refining and chemical equipment, and then mixing the multifunctional modified aromatic hydrocarbon mother liquor with aromatic hydrocarbons Preparation of multifunctional modified aromatics by homogenization device.

[0064] The preparation method is specifically:

[0065] Aromatics containing modifiers are continuously transported from the feed port of refining unit to refining room I by branch pipe metering pumps. In refining room I, aromatics and modifiers are under the action of medium balls and stirring mechanisms. Refining, and then transported through the column filter to the refining room of the next level for more refined refining, and finally discharged from the outlet of the last level of refining room to pro...

Abstract

The invention relates to the field of chemical equipment, and discloses a multifunctional modified aromatics manufacturing equipment and preparation method, including a refining device and a homogenizing device; the refining device includes a refining cylinder and a stirring mechanism; the refining cylinder is equipped with N refinery chambers; pipelines are installed between adjacent refinery chambers, and column filters are installed on the pipelines; the stirring mechanism includes stepping motors, rotating shafts, inner magnetic rotors, isolation sleeves, outer magnetic rotors, stirring supports and stirring blades ;Inner magnetic rotor, spacer sleeve and outer magnetic rotor are sleeved on the rotating shaft in turn, and the outer magnetic rotor is provided with a stirring support; the main conveying pipeline of the homogenization device is divided into a jet mixing section, a static mixing section and an ultrasonic mixing section; the jet mixing There are branch pipes in the section. The invention can realize one-time continuous completion of ultra-fine grinding, fractionation, mixing and refining of modifiers, and continuous mixing of modified aromatic hydrocarbon mother liquor and aromatic hydrocarbons; it can make the blends accommodate and disperse each other liquid phase stability.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a production equipment and a preparation method of multifunctional modified aromatic hydrocarbons. Background technique [0002] Modifier liquid blending and grinding modification is to mix and grind two or more materials in a liquid state, and the particles of the dispersed phase are crushed and ultra-fine to achieve a stable state of the liquid phase in which the blends accommodate and disperse each other. It is a simple and effective material modification technology. [0003] When carrying out multifunctional modification of aromatic hydrocarbons, it is first necessary to blend, grind, refine and modify inorganic materials with aromatic hydrocarbon mother liquor. After obtaining the modified aromatic hydrocarbon mother liquor, it is then homogenized with aromatic hydrocarbons to obtain multifunctional modified aromatic hydrocarbons. [0004] However, the existing liquid grin...
