Description

Technical Field

[0001] The present invention discloses a dosing tank cleaning structure for an air flotation machine and an air flotation machine, and relates to a dosing tank cleaning structure used on an air flotation machine, and belongs to the technical field of sewage treatment, and particularly relates to a dosing tank cleaning structure that stirs water flow in different directions by stirring blades at different angles, and drives a scraper to clean the inner wall of a flocculation box by rotating a rotating roller, so as to realize automatic cleaning of the inner wall of a flocculation box. Background Art

[0002] Air flotation machine is a kind of equipment used for water treatment, mainly used in chemical plants, drinking water treatment, industrial wastewater treatment and other fields. Its working principle is to inject air or other gases into the water to generate a large number of tiny bubbles, and use these bubbles to adsorb impurities such as suspended matter, grease, etc. that are difficult to remove by natural sedimentation or floating in the water, so that they float on the water surface, thereby achieving solid-liquid separation. The traditional air flotation machine mainly includes components such as dosing device, dissolved air system, air flotation tank and scraping mechanism. The sewage first enters the reaction tank and mixes with the added flocculant to produce flocculation reaction, and then enters the contact tank to combine with the tiny bubbles in the dissolved air water to form floccules, enter the separation tank and float to the water surface to form scum, and finally the scum is scraped into the scum collection tank by the scraping mechanism for discharge. However, in traditional flotation machines, flocculants are added into the reaction tank through a dosing device. When the flocculants are added, they only exist in a certain position of the reaction tank, and the addition is uneven. Since the sewage continuously flows into the reaction tank at a certain flow rate, the sewage and the flocculant cannot fully contact each other before entering the next link, so that part of the sewage cannot be flocculated and floccules cannot be produced, resulting in low sewage treatment efficiency and poor treatment effect; and the tiny bubbles generated in the dissolved air system are also only concentrated in a certain position of the contact tank and cannot quickly diffuse to various areas of the contact tank, resulting in some floccules cannot be fully bonded with the tiny bubbles and cannot produce scum, resulting in low sewage treatment efficiency and poor treatment effect.

[0003] Announcement No. CN217895336U discloses a flotation machine with a sludge dewatering device, including an equipment body, the equipment body is divided into a dosing pretreatment unit, a flotation reaction treatment unit and a sludge dewatering treatment unit by a stainless steel partition, the dosing pretreatment unit includes a coagulant dosing reaction zone and a coagulant dosing reaction zone, the flotation reaction treatment unit is provided with a perforated water distribution pipeline, a dissolved air releaser, a mud discharge pipeline, an emptying pipeline, a slag scraping device, and a slag collection tank, and the sludge dewatering treatment unit includes a dehydration rotating motor and a dewatering tank. The above-mentioned flotation machine is provided with a coagulant dosing reaction zone agitator and a coagulant dosing reaction agitator, which can promote the full contact between sewage and flocculants and produce more floccules, but the tiny bubbles generated by the dissolved air tank in the above-mentioned flotation machine are only concentrated at a certain position of the equipment body through the dissolved air releaser, and cannot be quickly diffused to various areas of the equipment body, resulting in that some floccules cannot be fully bonded with the tiny bubbles and cannot produce slag, thereby resulting in low sewage treatment efficiency and poor treatment effect.

[0004] The applicant has designed a flotation machine to solve the above-mentioned problem, which includes a separation tank, a scraper plate, a slag collection tank, a rotating motor, a flocculation box, a contact box, spiral blades, a blower, a disc aerator, a rotating blade and other structures. However, when the flocculation box of the flotation machine is cleaned, water can only be injected for sufficient stirring so that the water flow carries the pollutants and is discharged from the water outlet. However, the flocculation box treats sewage for a long time, and sludge and other pollutants that cannot be washed away by water flow will remain on the inner wall of the box. The pollutants accumulate on the inner wall of the flocculation box, which may affect the mixing uniformity of the agent and water, so that the agent cannot fully play its role, thereby reducing the treatment effect.

The flotation machine is more integrated as a whole, occupies a smaller area, and can be used in places with limited space. The design of the separation tank (1) and the slag collection tank (7) forming an annular structure can effectively improve the dynamic characteristics of the sewage flow, so that the sewage forms a circulation between the separation tank (1) and the slag collection tank (7), thereby obtaining a more stable fluid motion state, thereby reducing the drift of micro-bubbles in the separation tank (1), increasing the residence time of micro-bubbles, facilitating the contact between micro-bubbles and suspended particles in the water, facilitating the separation and collection of slag, and improving the treatment efficiency of the flotation machine; The separation tank (1) and the slag collection tank (7) form a ring-shaped structure, which can extend the flow path of the sewage, so that the sewage can be discharged from the flotation machine after being fully treated, thereby reducing the risk of short-circuiting and improving the treatment effect of the flotation machine; The design of the separation tank (1) and the slag collection tank (7) forming an annular structure can prolong the residence time of sewage in the annular separation tank (1), so that suspended particles and flocs in the water have more time to float up to become scum or settle to become sludge, thereby achieving a better solid-liquid separation effect.
