できない。Conventionally, powdered ion exchange resin used in condensate filtration equipment in thermal power plants and nuclear power plants has been manually poured directly into precoat material supply tanks, but in recent years, especially in shallow water filtration equipment 4 for nuclear power plants, Due to the large amount of powdered ion-exchange resin used and to prevent operator exposure to radiation, methods and devices have been adopted to automatically charge the pre-coat material into the supply tank. It is not possible to measure the powder to 6 (grams), and if the feeder is installed at the bottom of the hopper, the powder may stick together or cause bridging, making smooth transfer impossible.

In the figure, the left side shows, for example, a cationic powder resin system, and the right side shows an anionic powder resin system, and since the components are the same, the anionic powder resin system is shown with a dashed number. The cationic powder resin thread will be described below, but the same applies to the anionic powder resin thread.

The powder passes through a discharge pipe 9 to a metering tank 6, and a second rotary blade feeder 4 is attached to the lower part of the metering tank 6. 4
It is a mechanical stile. The powder is introduced into the precoat material supply tank 5 from the discharge pipe 10. The weighing tank 6 and the second rotary blade feeder 4 are mounted on a common pedestal 7 via a load cell 6. The weighing tank 3 and the second rotary difficult feeder 4 are completely separated from other equipment by a universal joint 8, and a load cell 6 is used to prevent errors when measuring the weight of the tank. It is designed to stop at the first rotary feeder 2 depending on the amount of waste in the measuring tank.

の落下粉末量は小さいので精度良く排出できる。The first rotary type feeder 2 is configured to stop rotating in response to a signal from the load cell 6 when the amount in the measuring tank 3 becomes approximately 10% larger than the prescribed input limit. In addition, the rotor of the second rotary vane feeder is initially 5 to 8
While rotating at r, p, m, and measuring with the load cell 6, about 90% of the specified input amount is discharged into the precoat material supply tank 5, and then the rotation speed is reduced to about 1/10, and the remaining 10%
discharge. By doing this, it is possible to increase the number of squares and improve the accuracy by a total of 1111. Since the Il amount mass of the second rotary vane feeder is small, even if the rotation of the rotor is stopped, the amount of powder falling from the weighing mass is small and can be discharged with high accuracy.
