Abstract

The invention discloses a method for determining the contour of a dead angle side slope of a sedimentation tank. The method comprises the following steps: determining the contour of a circumference formed by the bottom surface of the dead angle side slope based on a predetermined filling angle and a predetermined height of the slope at the bottom of the tank, equally dividing the pool wall corresponding to a quarter of the circumference formed by the bottom surface of the dead angle slope into a plurality of sections, forming a plurality of equal division points on a bottom line where the poolwall is intersected with the pool bottom, measuring a distance between each of the plurality of equal division points and a corresponding one of the plurality of circumferential intersection points,vertically and upwards extending a corresponding distance from each of the plurality of equal division points along the pool wall so as to form a plurality of matching points corresponding to the plurality of equal division points on the pool wall, determining the length of the corresponding distance based on a predetermined filling angle, and respectively connecting the plurality of matching points and the plurality of circumferential intersection points to form a plurality of connecting lines, wherein the plurality of connecting lines form the outline of the dead angle slope.

Description

technical field [0001] The invention relates to a method for determining the contour of a dead slope of a sedimentation tank. Background technique [0002] Sedimentation tanks (especially high-density sedimentation tanks) are buildings that use coagulants and flocculants to contact, adsorb and settle impurities in raw water to separate mud and water. The structure of the tank body in the clarification area of ​​the sedimentation tank is generally a square structure. The sludge entering the clarification area settles evenly to the bottom of the tank. A mud scraper is installed at the bottom of the clarification area. The mud scraper takes the drive shaft as the center of the circle and the scraper arm as the radius. During the process, the sludge settled in the clarification area is scraped into the sludge collection device. [0003] However, because the four corners of the bottom of the pool (referred to as "dead corners") exceed the radius of rotation of the mud scraper, t...
