Description

Technical Field

[0001] The invention discloses a double-port dosing structure of an air flotation machine and an air flotation machine, and relates to a dosing hopper structure used on a dosing tank in the air flotation machine, and belongs to the technical field of sewage treatment, and particularly relates to a dosing hopper structure which is separated by a partition and can simultaneously inject two agents into a flocculation box without contacting each other, and realizes the opening and closing of the dosing port by fixing the fan leaf pieces by a spring hinge and a limiting ring, thereby minimizing the influence of the external environment on the inside of the 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 and combines with the tiny bubbles in the dissolved air water to form floccules, enters the separation tank and floats to the water surface to form scum, and finally the scum is scraped into the scum collecting 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 problems, 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. The sewage enters the flocculation box to react with the drug, the flocs and the sewage enter the contact box, and are fully bonded with the bubbles to form foam flocs. Finally, the foam flocs and the sewage enter the separation tank, and the foam flocs float to the water surface to form scum, which is scraped by the scraper plate to the slag collection tank and discharged through the slag discharge hole. However, when adding flocculants to the flocculation component, coagulants cannot be added to the sewage at the same time, and the flocculants are usually added in batches. The coagulants can only be added after the flocculants are added, which is time-consuming and labor-intensive. In addition, the dosing hopper is an uncovered structure. If solid garbage or other garbage falls from the dosing hopper into the flocculation box, it will affect the reaction of the drug and reduce the sewage treatment efficiency. Summary of the invention

[0014] The conical structure may be a pyramidal structure, and the columnar structure may be a prismatic structure, which can guide the medicine from the corners, making the conical structure more stable and more effective when bearing pressure, and can simplify the manufacturing process of the medicine adding hopper (12), reduce production costs and improve efficiency; The design that the conical structure and the cylindrical structure are detachably connected by threads makes the assembly and disassembly process easier and more efficient, facilitates adjustment and replacement, and saves maintenance time and cost; The partition (32) and the conical structure are slidably connected via a slide rail, so that the partition (32) can be relatively freely adjusted in position, which is convenient for disassembly and assembly, and reduces maintenance time and cost; The fan leaf (35) is designed to be divided into three parts, so that the opening and closing of the two areas can be controlled without affecting each other, and the third fan leaf (35) is used to improve its stability, enhance its performance and efficiency; The design of the stop ring (33) and the spring hinge (34) cooperates so that the fan leaf (35) rebounds to the stop ring (33) under the pull of the spring hinge (34), so that the dosing hopper (12) can be closed, thereby preventing solid waste from falling into the flocculation box (15) and reducing the sewage treatment efficiency.

[0015] The purpose is to separate the dosing hopper (12) by the partition (32), to inject two kinds of drugs into the flocculation box (15) at the same time without contacting each other, to fix the fan leaf (35) by the spring hinge (34) and the limit ring (33), to realize the opening and closing of the dosing port, and to minimize the influence of the external environment on the inside of the flocculation box (15).
