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; like 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 directi...

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 the refinery unit to refinery chamber I by branch pipe metering pumps. In refinery chamber I, aromatics and modifiers, 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...

Abstract

The invention relates to the field of chemical equipment and discloses manufacturing equipment and a preparation method of multifunctional modified aromatic hydrocarbon. The manufacturing equipment comprises a refining device and a homogenizing device, wherein the refining device comprises a refining barrel and a stirring mechanism; N refining chambers are arranged in the refining barrel; a pipeline is arranged between the adjacent refining chambers, and a column type filter is arranged on each pipeline; the stirring mechanism comprises a stepping motor, a spindle, an inner magnetic rotor, anisolation sleeve, an outer magnetic rotor, a stirring support and a stirring blade; the inner magnetic rotor, the isolation sleeve and the outer magnetic rotor sequentially sheathe the spindle, and the stirring support is arranged on the outer magnetic rotor; a main transmission pipeline of the homogenizing device is divided into a jet flow mixing section, a static mixing section and an ultrasonicmixing section; and a branch pipe is arranged in the jet flow mixing section. The manufacturing equipment disclosed by the invention can realize one-time continuous completion of ultrafine grinding and fractional separation, mixing and refining of a modifier as well as continuous material mixing of modified aromatic hydrocarbon mother liquor and aromatic hydrocarbon, and blends can be in a liquid-phase stable state, namely the blends accommodate each other and are dispersed mutually.

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...
