Description

Technical Field

[0001] The utility model relates to the technical field of wastewater cleaning, in particular to a water inlet device for a high-pressure dissolved air tank of an air flotation machine. Background Art

[0002] Air flotation machine is a widely used equipment in the field of sewage treatment, mainly used to achieve solid-liquid separation. The working principle of air flotation machine is mainly based on the principle of buoyancy and adhesion. In the air flotation machine, a large number of tiny bubbles are generated in a specific way. These bubbles collide with and adhere to the suspended particles in the sewage. Since the density of bubbles is much smaller than that of water, when the bubbles combine with the suspended particles, the overall density will decrease, thus being affected by buoyancy. Under the action of buoyancy, the bubbles and the suspended particles float to the water surface together, forming scum, achieving solid-liquid separation, and finally the scum is scraped off by the scraper to complete the cleaning purpose.

[0003] The existing dissolved air tank booster pump water inlet is in the clean water buffer tank, and the conduit is connected to the booster pump through the inside of the flotation machine. It is very easy to be corroded by long-term contact with wastewater. At the same time, cleaning and maintenance are more troublesome. During cleaning and maintenance, the internal sewage needs to be discharged cleanly, and manual entry is required. The gas produced by the fermentation of sewage is corrosive, and inhalation by the operator will affect his health. In addition, the existing pipeline is fixed with a flange and multiple sets of fixing bolts, and disassembly is also more troublesome. Therefore, we propose a flotation machine high-pressure dissolved air tank water inlet device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The embodiment of the present application provides a water inlet device for a high-pressure dissolved air tank of an air flotation machine, which solves the problem that the water inlet of the existing dissolved air tank booster pump is in the clean water buffer tank, and the conduit is connected to the booster pump through the inside of the air flotation machine. It is very easy to be corroded by long-term contact with wastewater, and it is more troublesome to clean and maintain. During cleaning and maintenance, the internal sewage needs to be discharged cleanly, and manual entry is required into the machine body. The gas generated by fermentation in the sewage is corrosive, and inhalation by the operator will affect his health. In addition, the existing pipeline is fixed with a flange and multiple sets of fixing bolts, and disassembly is also more troublesome.

[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] The utility model embodiment discloses a water inlet device for a high-pressure dissolved air tank of an air flotation machine.

[0024] According to the attached Figure 1-4As shown, it includes a body 1, a dissolved gas tank 2 is fixedly installed on one side of the body 1, a clean water buffer tank 6 is fixedly installed on the other side, a pressure pump 3 is arranged on the outer surface of the body 1, and first conduits 4 are movably inserted on both sides of the pressure pump 3, and the other end of the first conduit 4 is connected to the inside of the dissolved gas tank 2 and the clean water buffer tank 6, and a quick disassembly mechanism 5 is arranged between the pressure pump 3 and the first conduit 4, and the quick disassembly mechanism 5 includes a fixed plate 501, a movable plate 502, a wedge-shaped slot 503, a slider 504 and a fixing member 505;

[0025] When the device is in use, the pressure pump 3 draws water from the clean water buffer tank 6 through the first conduit 4 and draws it into the air dissolving tank 2. The air dissolving tank 2 forces the air to dissolve in the pressurized water to form saturated air-dissolving water. When the air-dissolving water is released into the body 1 at normal pressure by the air dissolving tank 2 through the second conduit 7, the air dissolved in the water will form a large number of microbubbles and precipitate. These microbubbles will combine with the suspended matter in the sewage to reduce the density of the suspended matter and float to the water surface, thereby achieving solid-liquid separation. When the conduit needs to be replaced or repaired, the fixing bolt 5052 is unscrewed, the movable disk 502 is rotated counterclockwise to make the slider 504 slide out of the wedge-shaped slot 503, the conduit that needs to be replaced and repaired is removed and replaced with a new one, and the fixed disk 501 is aligned. Insert the slider 504 at the end of the movable disk 502 into the wedge-shaped groove 503, and rotate the movable disk 502 clockwise to make the slider 504 slide along the wedge-shaped groove 503, so that the movable disk 502 moves toward one end close to the fixed disk 501, so as to be pressed against the sealing strip 507 to achieve sealing, and at the same time align the movable disk 502 with the fixing hole 5051 opened on one side of the fixed disk 501, insert the fixing bolt 5052 into the fixing hole 5051 and tighten it to complete the fixation of the quick-release mechanism 5. The movable disk 502 and the fixed disk 501 can be fixed by themselves once, so that only one set of fixing parts 505 is needed to complete the fixation of the entire quick-release mechanism 5, and the disassembly is also very convenient to meet the needs of users.

[0026] The fixed disk 501 is fixedly installed on one side of the booster pump 3, the movable disk 502 is rotatably connected to the end of the first conduit 4, the wedge-shaped slot 503 is opened inside the fixed disk 501, and multiple groups of wedge-shaped slots 503 are distributed in an annular manner inside the fixed disk 501, the slider 504 is set at the end of the movable disk 502, the slider 504 slides inside the wedge-shaped slot 503, the fixing piece 505 is set on one side of the fixed disk 501 and the movable disk 502, and the fixing piece 505 is movably engaged with the fixed disk 501 and the movable disk 502.

[0027] The fixing member 505 includes a fixing hole 5051 and a fixing bolt 5052;

[0028] The fixing hole 5051 is opened on one side of the fixed plate 501 and the movable plate 502, and the fixing bolt 5052 is threadedly connected to the inside of the fixing hole 5051. The fixing bolt 5052 further fixes the position of the movable plate 502 and the fixed plate 501 so that they will not fall off.

[0029] A fixed rod 506 is fixedly mounted on the end of the movable disk 502 , and the fixed rod 506 is fixedly connected to the slider 504 .

The movable disk 502 and the sealing groove 508 inside the fixed disk 501 are movably engaged with the sealing strip 507, ensuring that water will not leak from the quick disassembly mechanism 5, meeting the needs of users.

[0032] A second conduit 7 is provided at the bottom of the air dissolving tank 2, and the other end of the second conduit 7 is fixedly installed inside the body 1. When the air-dissolving water is released into the body 1 at normal pressure through the second conduit 7 by the air dissolving tank 2, the air dissolved in the water will form a large number of microbubbles and precipitate.
