Abstract
PURPOSE: Air blowing tube is installed adjacent to the supporting plate lower part. By doing so, air is uniformly lifted up in the filtering layer for the break away of suspension from filtering material.
CONSTITUTION: An air blowing tube 3 is installed very adjacent to the lower part of a supporting plate 1 in which a hollow leg 5a of a strainer 5 is projected downward and an air zone 7 by the air blown from this blowing tube 3 is formed beneath the supporting plate 1. Then, this air zone 7 gradually lowers to thicken its thickness and finally lower part of aforesaid hollow leg 5a is exposed to the water level of a lower chamber 6. Through this exposure, air forming the air zone 7 enters to the hollow leg part 5a from its lower part and it is injected from a water passing hole 5c through a hollow head 5b of the strainer 5 to a filtering layer; 2 and 4, supported to above mentioned supporting plate 1 and it lifts up uniformly through the filtering layer; 2 and 4 and then it agitates the filtering material wholly to break away the suspension stuck in the filtering material.
