Embodiment Construction

[0019] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0020] Such as figure 1 As shown, a low energy consumption buoyancy propulsion type slag scraping device includes a floating ball 11 arranged in the ozone gas floating cylinder 1, and the floating ball 11 is connected to the track bracket 6 on the top of the ozone gas floating cylinder 1 through an expansion and contraction bracket 12 Above, the track support 6 is a parallel double track, and the structure and the parts arranged thereon are exactly the same.

[0021] The expansion bracket 12 is an inverted V-shaped structure, which is connected by two rods through a horizontal shaft. The lower end of the rear rod is connected to the floating ball 11, and the lower end of the front rod is connected to the curved slag scraper 13 with the inner arc facing downward. The horizontal rotating shaft is slidably arranged on the track support 6 and is pe...

Abstract

A low-energy-consumption buoyancy pushing type scum scraping device comprises a floating ball arranged in an ozone floatation column, the floating ball is connected to a rail bracket on the top of the ozone floatation column through an extending and contracting support which is of an inverted V-shaped structure, the extending and contracting support is formed by connecting two rods through a horizontal rotating shaft, the lower end of the rod located on the rear portion is connected with the floating ball, the lower end of the rod located on the front portion is connected with an arc-shaped scum scraping plate, the horizontal rotating shaft is arranged on the rail bracket in a slidable mode and is perpendicular to the rail direction, a spring for horizontally abutting against the rotating shaft is arranged on the rail bracket, and the arc-shaped scum scraping plate and the spring are located in front of and behind the floating ball respectively. Compared with a traditional closed scum extruding technology, by means of the low-energy-consumption buoyancy pushing type scum scraping device, the problems that the traditional technology is larger in energy consumption, and more equipment is used are solved; meanwhile, automatic operation is easy to conduct, the treatment effect is stable, and important significance in the field of advanced wastewater treatment is achieved.

Description

technical field [0001] The invention belongs to the technical field of advanced sewage treatment, and in particular relates to a buoyancy propulsion type slag scraping device with low energy consumption. Background technique [0002] As an advanced treatment process for urban sewage, the ozone flotation process has the characteristics of good organic matter and chroma removal effect, short residence time, and small footprint. The top of the traditional vertical flow air flotation process device is sealed with a slag discharge pipe, relying on the rise of the water level during the operation cycle to squeeze the scum into the slag discharge pipe for discharge. During this process, frequent slag extrusion tends to cause a large amount of scum to adhere to the top and surrounding of the wall, and these walls have a high density of scum, which is easy to break away from the wall and sink to the reaction when the liquid level rises and falls periodically and is impacted by the wa...
