More specifically, with respect to the manufacturing method, the solid content separation is performed in the same tank and Z or the flange directly connected to the same tank in which the operation for obtaining the slurry suspension is performed. It is about.
- Examples of the slurry suspension that can be used in the present invention include suspensions of polymer particles, crystallized particles, metal particles, and the like. Among them, a slurry-like suspension obtained by agglomerating and agglomerating particles suspended or dispersed as fine particles in a solution from the viewpoint that the solid content is not solid and the solid content is not adhesive. U, prefer to be. Although the solid content is very small, particles that have passed through filtration may accumulate in the valve part, causing damage to the nozzle during opening and closing operations. This is because there is a risk of clogging and blocking the filtration surface.
- a polymer latex is obtained using water as a solvent and various monomers, emulsifiers, and catalysts, and then a slurry suspension containing polymer particles agglomerated and enlarged by a coagulant such as saline or hydrochloric acid. Turbid I can give it.
- a slurry suspension containing a polymer with few impurities can be raised by adding a solvent such as methanol having a high polarity to the latex of polymer particles.

- the opening area per hole is preferably 0.002 to 3 cm 2 , more preferably 0.01 to 1.2 cm 2 .
- opening area per the hole one place is less than 0. 002cm 2, since the separation speed is significantly slow, it becomes wider than 3 cm 2 in the reverse loss solids are in tended to increase rapidly It is.
- the particle size of the solid content in the slurry suspension is preferably a number average particle size of 0.05 mm or more, more preferably 0.2 mm or more. If the solids particle size is less than 0.05 mm, the particle size is too small and the gaps between the particles are narrowed. As a result, the filtrate to be discharged passes through, and the filtration separation takes a long time. Tend to require. On the other hand, the upper limit of the particle size of the solid content is preferably 10 mm.
- the average particle size can be measured by, for example, a Coulter counter using a commonly used electrical resistance method (such as Multisizer, manufactured by Beckman Coulter).

In this case, it is preferable that the flange portion is closer to the tank bottom discharge outlet portion.
- the perforated plate is brought closer to the tank bottom by inserting it from the flange. It is preferable. This is because if the distance between the tank bottom outlet and the perforated plate is increased, the piping portion becomes a dead space in the subsequent operations such as reslurry, and there is a high possibility that the solid content remains.
- the slurry suspension immediately after performing the agglomeration operation has a generally uniform slurry concentration under the agitation operation, so the agitation operation is performed before the separation operation by filtration. It can be stopped and allowed to stand for a certain period of time, and then the filtration operation can be performed after the solid particles float or settle.
- the discharge rate of the filtrate in the filtration operation is no limitation, when the floating particles start to settle immediately after the filtration operation or during the filtration operation, the solid content is relatively easily discharged along with the filtrate through the perforated plate. It is desirable to slow down to a certain extent.
- the discharged filtrate can be returned again to the tank during the filtration operation.
- the outflow of solid content in the slurry suspension can be prevented by performing the filtration operation in combination with the interface detection sensor and the control sequence.
- the solid content in the slurry-like suspension filtered by such a method remains in the tank, and operations such as reslurry, dissolution, or dispersion can be subsequently performed.
- These operations such as reslurry, dissolution, or dispersion can be performed by a general method in which a solvent such as water or a solvent is introduced into the tank and a stirring operation is performed for a certain period of time.
- a solvent such as water or a solvent
- a stirring operation is performed for a certain period of time.
- the solvent include water, methanol and hexane for the purpose of washing as described above, and acetone and methyl ethyl ether for the purpose of dissolution and dispersion.
- the solid content can be separated without carrying the slurry-like suspension in the tank out of the tank or using the filtration apparatus outside the tank, and the same tank is used. Processing such as reslurry, dissolution, or dispersion, which is the next step, can be performed. Such a method simplifies the manufacturing process and reduces the construction cost, and in a system using a solvent, the solvent discharge to the environment can be remarkably suppressed.
- the production method of the present invention includes, for example,
