2. Description of the Related Art An electronic functional material, for example, a phosphor used for forming a fluorescent film of a color cathode-ray tube has impurities attached to its surface or contains impurity ions inside. When a phosphor film is formed using such a phosphor as it is, the quality of the phosphor film is significantly reduced. For this reason, the phosphor is dispersed in water to prepare a phosphor slurry, which is stirred to wash the phosphor by increasing the contact of the phosphor with water.

It comprises a speed reducer 38 built in the casing 37 and a motor 39 provided on the speed reducer 38 and having a drive shaft (not shown) coupled to the speed reducer 38. The rotating shaft 40 has an upper end coupled to the speed reducer 38 and a lower end penetrating the support plate 35 and inserted into the cleaning tank 31.

First, a desired amount of the slurry 43 to be cleaned (for example, an amount slightly lower than the upper opening of the cleaning tank 31) is supplied into the cleaning tank 31 from a supply pipe (not shown). By rotating the motor 39 of the rotating mechanism 36, the rotating shaft 40 connected to the speed reducer 38 is rotated, and the stirring blade 41 at the lower end thereof is rotated. Such rotation of the stirring blade 41 generates a horizontal vortex in the slurry 43 to be cleaned in the cleaning tank 31 and, as shown by a dashed line in FIG.
The baffle plates 42a and 42b generate a flow (vertical flow) from the vicinity of the inner wall surface of the cleaning tank 31 toward the center and further downward from that location. For this reason, the stirring efficiency of the electronic functional material (for example, phosphor) in the slurry to be cleaned is increased, and the chance of contact with water is increased, thereby removing impurities and the like on the surface.

However, in the case of a structure in which two baffle plates 42a and 42b are arranged in the cleaning tank 31 to change the flow of the slurry to be cleaned, as shown in FIGS. Since turbulence occurs near the plates 42a and 42b and accumulation occurs near the bases of the baffle plates 42a and 42b, electronic functional materials such as phosphors in the slurry to be cleaned are disturbed by the baffle plates 42a and 42b. Collision and damage. Damage to the electronic functional material not only lowers the quality of the product used, but also lowers the cleaning yield.
