Problems solved by technology

[0005] The object of the present invention is realized, and the main improvement is that the scraper arm of the rotary mud scraper used in the existing circular sedimentation tank, at least one end is provided with a parallelogram mechanism (parallelogram linkage) that can automatically swing back and forth radially according to the pool wall during the rotation process. , commonly known as the hinge four-bar mechanism) is a mud scraping device composed of auxiliary scraping arms, so that during the rotating mud scraping process, the mud scraper can make the square sedimentation tank All the settled sludge in the tank can be scraped to the center of the pool to be effectively removed, which overcomes the shortcomings of the existing rotary mud scraper that can only scrape mud in a circle and cannot run in a square track

Embodiment 1

[0021] Embodiment 1: referring to Fig. 1-4, the side length 6 of the water treatment sedimentation tank is a circular circumscribed square, and each adjacent surface is perpendicular to each other, and the center has the same central water distribution pillar similar to the circular sedimentation tank (not shown in the figure ), the bottom of the pool is inclined towards the center, and the pool body is equipped with a rotary mud scraper.

[0022] There are several main scrapers 12 on the scraper arm 13 of the rotary mud scraper, and there are vertical inclined supports 11 arranged obliquely at 45°±2° near both ends, and there are vertical shafts on the scraper arm and the inclined supports 9.1 and 9.2 and rotating sleeve 15.1 and 15.2 constitute rotating hinge 3 (Fig. 1, 4). The parallelogram mechanism composed of rods 5 and 2 is movable and hinged on the scraper arm 13 and the oblique support 11 through two living hinges 3 parallel to the pool plane, wherein the parallelogra...

Embodiment 2

[0023] Embodiment 2: referring to Fig. 5, as embodiment 1, omit gravity counterweight, a fixed rod 17 is set on scraper 13 upper arm, extension spring 16 is set between rod 17 and parallelogram bar 5.1, the pulling force that extension spring produces, same The parallelogram mechanism can always be kept outwardly stretched and deformed, so that the roller 8 at the opposite end of the rod member 2 of the parallelogram scraper arm can always keep sticking to the wall surface of the pool.

Embodiment 3

[0024] Embodiment 3: Referring to Fig. 6, as in Embodiment 1, the gravity counterweight is omitted, and a guide groove 18 is provided on the peripheral surface 6 of the pool wall, so that the end of the parallelogram scraper arm opposite to the rod 2 is movable into the guide groove through the roller 19 , the parallelogram mechanism can also be kept stretched and deformed all the time, so that the parallelogram scraper arm facing bar 2 can always keep sticking to the wall of the pool.

Abstract

The invention discloses a water processing flow tank and rolling scraper improvement method, which is characterized by the following: the flow tank section is round externally tangent square with the length of edge equaling to diameter, wherein the flow tank section installs rolling scraper; at least one end of turning scraping arm is linked to parallelogram device paralleling to tank plane; the opponent bar of parallelogram scraping arm installs scraping mud device; the parallelogram bar keeps deforming to external diameter with the action of present apparent force which can make the outer opponent bar of parallelogram scraping arm abutting to square tank wall and proceeding radial oscillating traverse motion. The invention has the advantages of round flow tank and rectangle flow tank, which overcomes the shortage of two.

Description

technical field [0001] The invention relates to the improvement of the water treatment sedimentation tank and the rotary mud scraper, in particular to a square sedimentation tank which integrates the advantages of the circular sedimentation tank and the rectangular sedimentation tank, and which can scrape the sludge at the four corners of the square sedimentation tank rotary mud scraper. Background technique [0002] In the water supply and drainage system, sedimentation tanks or clarification tanks are usually divided into rectangular (advection) sedimentation tanks and circular sedimentation tanks according to the plane shape (section) of the tank. According to the sedimentation mechanism, the hydraulic characteristics and sedimentation effect of the circular sedimentation tank should be It is superior to the rectangular sedimentation tank, and the rotary mud scraping device can be used to make a large-diameter sedimentation tank. Therefore, the circular sedimentation tank...
