Problems solved by technology

However, since the functional powder slurry often uses diol monomer as a solvent, when it is mixed with polyester oligomers, there is often a problem that the excess diol monomer evaporates instantaneously at high temperature and the functional powder reunites.

Embodiment 1

[0051] As an embodiment of the present invention, this embodiment provides a high shear reactor, such as figure 1 As shown, there is a reaction chamber inside the high shear reaction kettle, and a shear jet device is arranged in the reaction chamber, including,

[0052]A radial flow stirring paddle, located inside the reaction chamber, has a rotating shaft and a paddle, and is used to drive the reactants to flow in the radial direction;

[0053] a shear jet mechanism, located inside the reaction chamber, fixedly connected with the inner wall of the reaction chamber, and has a cavity for accommodating the radial flow stirring paddle;

[0054] The radial flow stirring paddle is located in the shear jet mechanism, which provides power for the reactants in the cavity, so that the reactants are sprayed to the outside through the shear jet mechanism, which realizes the full dispersion of the functional powder in the reactants and avoids the function of Agglomeration of powders.

Embodiment 2

[0064] As another embodiment of the present invention, this embodiment is further improved on the basis of Embodiment 1, and the details are as follows.

[0065] like Figure 4 and Figure 5 As shown, in this embodiment, the high shear reactor also includes,

[0066] The baffle 802 is fixed on the guide tube 8 and extends inward from the inner wall of the guide tube 8 .

[0067] The baffle 802 is located on one side of the paddle along the axial direction of the guide tube 8, and is fixedly connected with the inner wall of the guide tube 8.

[0068] Specifically, the plane where the baffle plate 802 is located is parallel to the axis of the guide tube 8 , and the length along the radial direction of the guide tube 8 is greater than the gap between the guide tube 8 and the end of the blade , the radial flow stirring paddle 9 drives the reactant to move in the circumferential direction of the diversion cylinder 8 during the rotation process. When passing through the baffle 80...

Embodiment 3

[0074] As another embodiment of the present invention, the embodiment of this city makes further improvements on the basis of the second embodiment, and the details are as follows.

[0075] In this embodiment, the radial flow stirring paddle 9 and the guide cylinder 8 are located at the lower part of the reactor, and an axial flow stirring paddle for guiding the reactants to flow along the axial direction to the radial flow stirring paddle 9 is also provided in the reactor. 10, the axial flow stirring paddle 10 can be arranged above or below the radial flow stirring paddle 9; the above-mentioned scheme is formed in the reactor by the radial flow stirring paddle 9, the guide cylinder 8 and the axial flow stirring paddle 10 for the circulation of the reactants. The passage of the duct, so that the reactants located outside the diversion cylinder 8 can be continuously supplemented into the interior of the diversion cylinder 8, thereby realizing the full dispersion of the functiona...

Abstract

A plurality of partition plates extending upwards from the bottom are arranged in the reaction kettle, gaps are formed between the partition plates and the top wall of the reaction kettle, a plurality of reaction cavities which are arranged side by side and sequentially communicated are formed in the reaction kettle, and the sizes of the gaps between the partition plates and the top wall of the reaction kettle are adjustable. The partition plate comprises a fixed part connected with the bottom of the reaction kettle and a movable part movably connected with the fixed part, and the gap between the partition plate and the top wall of the reaction kettle is adjusted by adjusting the movable part, so that the flowing direction of reactants and the quantity of the reactants in the plurality of reaction cavities are controlled; meanwhile, the reaction time of reactants in the reaction cavity can be controlled by adjusting the height of the partition plate, the control method is simplified, and the control efficiency is improved; and the shear mixing device is also arranged in the reaction cavity, so that functional powder in reactants can be fully dispersed, agglomeration of the functional powder is avoided, and the performance of subsequent products is improved.

Description

technical field [0001] The invention belongs to the technical field of chemical equipment, and particularly relates to a continuous reaction kettle. Background technique [0002] At present, the preparation method of functional polyester fiber is mainly the master batch method. The masterbatch method is to first melt and mix functional powder and carrier resin to obtain functional masterbatch with high functional powder content, and then uniformly mix the functional masterbatch melt with the polyester melt for spinning to obtain functional polymer through the spinning process. Ester fiber. [0003] In the above process of preparing functional polyester fibers, the functional powder is mainly dispersed in the high-viscosity polyester melt by the mechanical shearing force provided by the mixing equipment, because the mechanical shearing force provided in the conventional equipment is small and uneven. , while the functional powder is dispersed, there is also the problem of a...
