Embodiment Construction
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0019] see Figure 1-3 , a slag scraping device for an air flotation machine, comprising a water treatment tank body 1, the inner top of the water treatment tank body 1 is fixedly connected with a chain group 2, and the outside of the chain group 2 is equidistantly connected with a slag scraper plate 3, the water treatment tank The inner bottom of the body 1 is fixedly connected with a baffle 4, and the water treatment pool body 1 is divided into two areas by ...

The invention relates to the technical field of wastewater treatment, and discloses slag scraping equipment for an air flotation machine, the slag scraping equipment comprises a water treatment tank body, the top end of the interior of the water treatment tank body is fixedly connected with a chain group, the outer side of the chain group is connected with slag scraping plates at equal intervals, and the bottom end of the interior of the water treatment tank body is fixedly connected with a baffle plate. When the slag scraping plate rotates and moves along with the chain set, the slag scraping plate extrudes the surface of the water bag, so that the water bag deforms in the deformable area, the extrusion of the water bag on the surface of the flat plate is enlarged, and when the water bag loses the extrusion of the slag scraping plate, namely in the process of recovering the shape of the water bag, interaction force is generated between the deformation area of the water bag and the surface of the flat plate; internal water pressure of the water bag is controlled through mutual pulling, so that water flow is continuously sprayed to the top end of the baffle plate and the interior of a slag collecting pool through a water through hole in the bottom end of the water bag, slag is shaken, bubbles in the slag collecting pool are broken, and the capacity of the slag collecting pool for suspended pollutants is increased.
Description
technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a slag scraping device for an air flotation machine. Background technique [0002] Air flotation is to use highly dispersed micro-bubbles as a carrier to adhere to the suspended pollutants in the wastewater, so that the buoyancy is greater than gravity and resistance, so that the pollutants float to the water surface to form foam, and then scrape the foam from the water surface with scraping equipment. The process of realizing solid-liquid or liquid-liquid separation. [0003] The slag scraping equipment used in the traditional air flotation machine drives the rotation of the chain group through two movable shafts, so that the scum scraper can push the floating scum to one side. When moving sideways, the scum on the slag scraper plate falls naturally into the slag collection pool on one side by gravity, so that the scum attached to one side of the slag scraper plate...
