Problems solved by technology

However, at present, there is no positive solution to determine the contour of the slope, which leads to the fact that the built slope cannot effectively realize the sludge collection function, and sometimes affects the operation of the sludge scraper, affecting the process operation and equipment life

Abstract

The invention discloses a method for determining the contour of a dead angle slope of a sedimentation tank, comprising the following steps: determining the contour of the circumference formed by the bottom surface of the dead angle slope based on a predetermined filling angle and a predetermined height of the slope at the bottom of the tank; The pool wall corresponding to a quarter of the circumference formed by the bottom surface of the slope is divided into multiple sections, and multiple equal points are formed on the bottom line where the pool wall and the pool bottom intersect; respectively connect the center of the pool bottom with multiple equal sections points forming multiple circle intersections on one quarter of the circle; measure the distance between each of the multiple equal points and the corresponding one of the multiple circle intersections; from each of the multiple equal points A corresponding distance is extended vertically upward along the pool wall, so that multiple matching points corresponding to multiple bisection points are formed on the pool wall, and the length of the corresponding distance is determined based on the predetermined filling angle; multiple matching points and multiple circumferences are respectively connected The intersection points form a plurality of connecting lines that compose the contour of the dead-end 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...
