Background
In the liquid reaction system, the operation of recycling the solid substance as a catalyst after the completion of the reaction is very complicated, and the effect is not satisfactory.
Disclosure of Invention
The invention aims to provide a method for automatically separating and recycling a solid catalyst in a liquid reaction, which can effectively separate the solid from the liquid in a reaction kettle and can simplify and facilitate the recycling operation of the solid catalyst.
The technical solution of the invention is as follows:
a method for automatically separating and recycling a solid catalyst in liquid reaction is characterized in that: the inner wall of the reaction kettle is uniformly distributed and fixed with a cylindrical steel wire mesh, cylindrical filter cloth tightly attached to the inner wall of the cylindrical steel wire mesh is arranged in the cylindrical steel wire mesh, and the filter cloth is fixed with the steel wire mesh and is prevented from deforming along with the flow of liquid in the reaction kettle;
the cloth filtering ports in the reaction kettle are distributed along the anticlockwise direction, in the reaction process of the system, the stirring in the kettle is stirred along the anticlockwise direction, and the solid catalyst is dispersed in the system and cannot enter the cloth filtering bag; after the reaction is finished, the stirring direction is changed into clockwise rotation, the solid catalyst enters the filter bag from the filter cloth opening along with the liquid, the liquid flows out of the filter cloth by using the driving force of stirring, and the solid is blocked by the filter cloth and is left in the filter cloth bag; the liquid flows along one direction and has a driving force provided by stirring, and the solid in the filter cloth bag cannot reversely flow out, so that the liquid continuously containing the catalyst solid enters, is separated by the filter cloth, the solid is left, and the liquid flows out until the liquid does not contain the catalyst solid; when the separated liquid is discharged from the reaction kettle, the clockwise rotation is also kept, so that the catalyst in the filter cloth bag is prevented from flowing out;
when new unreacted liquid is replenished in the reaction kettle, the stirring is adjusted to be anticlockwise rotated, the catalyst solid in the filter cloth bag is flushed by utilizing the flow of the liquid to be mixed into the liquid, and the anticlockwise rotation is kept until the reaction is finished.
The method does not need additional filtering equipment, can effectively separate the solid and the liquid of the system in the reaction kettle, and can ensure that the operation of recycling the solid catalyst becomes simpler and more convenient.

Detailed Description
A method for automatically separating and recycling a solid catalyst in a liquid reaction comprises the steps that a cylindrical steel wire mesh 2 is uniformly distributed and fixed on the inner wall of a reaction kettle 3, cylindrical filter cloth 1 attached to the inner wall of the cylindrical steel wire mesh is arranged in the cylindrical steel wire mesh, and the filter cloth is fixed with the steel wire mesh and is prevented from deforming along with the flowing of liquid in the reaction kettle (as shown in figures 1, 2 and 3);
the cloth filtering ports in the reaction kettle are distributed along the counterclockwise direction, in the reaction process of the system, the stirring in the kettle is stirred along the counterclockwise direction, and the solid catalyst is dispersed in the system and cannot enter the cloth filtering bag (as shown in figure 4).
After the reaction is finished, the stirring direction is changed into clockwise rotation, the solid catalyst enters the filter bag from the filter cloth opening along with the liquid, the liquid flows out of the filter cloth by using the driving force of stirring, and the solid is blocked by the filter cloth and is left in the filter cloth bag; the liquid flows along one direction and has a driving force provided by stirring, and the solid in the filter cloth bag cannot reversely flow out, so that the liquid continuously containing the catalyst solid enters, is separated by the filter cloth, the solid is left, and the liquid flows out until the liquid does not contain the catalyst solid; the separated liquid is discharged from the reaction kettle while being kept rotating clockwise to prevent the catalyst in the filter cloth bag from flowing out (as shown in fig. 5).
When new unreacted liquid is replenished into the reaction kettle, the stirring is adjusted to be anticlockwise rotated, the catalyst solid in the filter cloth bag is washed by the flowing of the liquid to be mixed into the liquid, and the anticlockwise rotation is kept until the reaction is finished (as shown in figure 6).
