Filed: 1991-08-27
Abstract: PURPOSE: To enable continuous supplying of powder by measuring momentary powder consumption. CONSTITUTION: At the time of consuming the powder in a mold 1, the height of powder is lowered and the powder in a supplying pipe 10 and a second hopper 18 flows downward. An opening end of a discharging pipe 15 is opened and the portion in the discharging pipe 15 at the lower side from a valve 17, is emptied out. After a fixed time period, the continuity between a principal hopper 13 and the second hopper 18 is broken off. The weight in the principal hopper 13 is measured by using a weight indicator 14 and the measured value is recorded. At the time of reopening the valve 17 after the lapse of a prescribed time according to the desired measuring accuracy for pre-estimated power consumption, the powder flows again in the pipe 15 and the second hopper 18 is filed up. Thereafter, the above process is repeated.

SOLUTION: When performing filtration treatment, a liquid to be treated is guided to the lower part of a filtration tower 1 from a passage 4 for the liquid to be treated and a turbid matter is uptake from the liquid to be treated by the filtration layer 3. The filtrate passes through a filtering medium support part 2, entering a liquid storage part 7. Further, the filtrate passes through a filtrate passage 9 to be stored in a storage tank 10 and then is delivered into a filtrate passage 12. When cleaning the filtration layer 3, the filtrate contained in the storage tank 10 is drained from a drain passage 6 while being sent to the liquid storage part 7, so that a turbid matter sludge is washed out. In addition, air is diffused in some area, e.g. an area A. If this air diffusion is performed with an air diffusion device 5a, the downward flow of a cleaning liquid is inhibited.  On the other hand, the downward current is formed in an area B in which the air diffusion does not take place, so that a filtering medium is engulfed into a gyrating current to peel the sludge.
