[0002] The stirred tank promotes the mutual dissolution of liquids, the mutual dissolution and mixing of two or more liquids, and the stirring of uniform liquids. It should be able to distinguish whether there is a chemical reaction in the uniform liquid mixture. Stirring tanks are mostly used in industrial production. When using stirring tanks, catalysts are often used, and many catalysts are spherical particles with very small diameters. After the reaction is completed, we need to remove the catalyst from the reactor.

[0003] The existing device filters the catalyst by setting up a drawer-shaped screening device. When the liquid is completely discharged, the filtered catalyst is taken out. However, by setting up the drawer screening structure on the mixing kettle, the staff is required to manually take out the drawer screening structure, and too much catalyst is accumulated on the screen, which is easy to affect the discharge speed of the mixing kettle.

[0004] Moreover, as the sealing between the drawer screening structure and the stirring kettle decreases with long-term use, leakage is likely to occur during the stirring process. Therefore, it is necessary to propose a stirring kettle capable of screening catalyst particles to solve the above-mentioned problems. Utility Model Content
