Abstract

PURPOSE: To continuously and quantitatively supply a slurry by controlling a pressure controller so that a slurry supply rate detected by a supply rate detecting sensor of the slurry supplied from a pressure tank to a nozzle may be a target value. CONSTITUTION: The slurry S is supplied from a supply port 4a into a pressure tank 4 to store, and a float 5 is floated on a surface of the slurry S. Then, a compressed air from a pressure source 1 is introduced into an upper part of the pressure tank 4 through a proportioning controlling valve 2 and an air tube 3. The pressure of this introduced compressed air is impressed on a surface of the float 5 in the pressure tank 4 to uniformly pressurize a liq. surface of the slurry S and the slurry S is flew out from the nozzle 10. Moreover, an opening degree of the proportioning controlling valve 2 which is the pressure controlling device is controlled so that the slurry S supply rate detected by an electromagnetic flowmeter 7 of the supply rate detecting sensor may be the target value. In this way, the slurry can be supplied continuously and quantitatively.

EXAMPLE FIG. 1 is a systematic diagram of a slurry quantitative supply device according to an example. Compressed air from a pressure source 1 such as a compressor is introduced into the upper portion of a pressure tank 4 via a proportional control valve 2 and an air tube 3. The slurry S is supplied from the charging port 4a and stored in the pressure tank 4, and the float 5 floats above the liquid surface of the slurry S. The bottom surface of the pressure tank 4 is roundly curved, and the lower surface of the float 5 is curved following the bottom surface of the pressure tank 4, so that when the float 5 sinks, almost the entire lower surface of the float 5 is pressure tank. It overlaps with the bottom surface of No. 4 to almost eliminate the residual slurry.
