Description

Technical Field

[0001] This utility model relates to the field of air flotation technology, and more specifically, to a novel air flotation device. Background Technology

[0002] In wastewater treatment, dissolved air flotation (DAF) technology is a highly efficient and widely used method. It involves injecting microbubbles into the wastewater, causing suspended solids to adhere to the bubbles and be carried to the surface as they rise, forming a foam layer and thus achieving solid-liquid separation. However, most existing dissolved air flotation systems only perform a single flotation stage, resulting in insufficient flotation of wastewater and incomplete removal of light suspended solids, leading to incomplete wastewater purification.

[0003] A search revealed that Chinese patent CN218345217U discloses a novel high-efficiency air flotation device. Through the design of valves, quick connectors, a primary air flotation release device, and a secondary air flotation release device, it improves upon the shortcomings of the original primary air flotation system, which was incomplete in purifying light suspended solids in wastewater. It also addresses the issue that the release device in the air flotation system was controlled by a single valve or quick connector, requiring shutdown for maintenance if the release device became clogged. The proposed device utilizes two quick connectors, two valves, a primary air flotation release device, and a secondary air flotation release device, thereby enhancing the air flotation effect on wastewater.

[0004] When the above-mentioned air flotation device is in use, air bubbles are released through the primary air flotation releaser and the secondary air flotation releaser. Countless micro bubbles rise to the surface and cause suspended matter in the water to adhere to the bubbles. However, it is inconvenient to adjust the depth of the air flotation releaser in the water. If the air flotation releaser is too deep or too shallow, the bubbles will not be able to fully combine with the suspended matter, thereby reducing the efficiency of air flotation treatment. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a novel air flotation device, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel air flotation device, comprising a suspension box and a dissolved air box, wherein the dissolved air box is fixedly installed at the top of the suspension box, an air compressor is fixedly connected to the rear side of the dissolved air box, a three-way hose is fixedly connected to the output end of the air compressor, and air flotation release devices are fixedly connected to both ends of the three-way hose. Movable components are provided on the two air flotation release devices, each movable component comprising a first stepper motor, a lead screw, a slide bar, and a slide plate. The output shaft end of the first stepper motor is fixedly connected to the lead screw, and the bottom ends of the lead screw and the slide bar both penetrate the slide plate. The two air flotation release devices are fixedly installed on the rear side of the slide plate.

[0007] Furthermore, a limiting ring is fixedly fitted at the bottom outer edge of both the lead screw and the slide rod.

[0008] It can be seen that the above technical solution limits the distance the skateboard can move downwards.

[0009] Furthermore, a piston is threadedly connected to the top of the dissolved gas chamber.

[0010] As can be seen, in the above technical solution, the piston is rotated and moved away from the dissolved air tank, and then raw water is added into the dissolved air tank.

[0011] Furthermore, each of the two air flotation release devices is fixedly connected to a control valve on its opposite side, and both control valves are fixedly installed on a three-way flexible hose.

[0012] As can be seen, in the above technical solution, closing one of the control valves can prevent one of the air flotation releasers from releasing microbubbles.

[0013] Furthermore, a support plate is fixedly connected inside the suspension box, the first stepper motor is fixedly installed on the top of the support plate, and the top of the slide rod is fixedly connected to the support plate.

[0014] It can be seen that the above technical solution facilitates the support and separation of the first stepper motor.

[0015] Furthermore, the support plate is provided with a guide assembly, which includes two first rotating shafts, two baffles, a second rotating shaft, a toothed belt, a second stepper motor, and two gears. The top ends of the two first rotating shafts are movably connected to the suspension box through bearings, and the bottom end of the second rotating shaft is movably connected to the support plate through bearings.

[0016] Furthermore, the top ends of the two baffles are respectively fixedly connected to two first rotating shafts, one of which is connected to the second rotating shaft via a toothed belt, and the other is connected to the second rotating shaft via two gears. The second stepper motor is fixedly installed inside the top of the suspension box, and the output shaft end of the second stepper motor is fixedly connected to the second rotating shaft.

[0017] It can be seen that the above technical solution is designed to facilitate the adjustment of the angles of the two baffles.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] 1. This utility model releases microbubbles through an air compressor and two air flotation releasers to adhere suspended solids in wastewater. The first step motor drives the lead screw to rotate, which in turn drives the slide plate to move downward, thereby moving the two air flotation releasers downward. The depth of the two air flotation releasers in the wastewater can be adjusted as needed. The operation is simple and convenient to adjust the depth of the two air flotation releasers in the water, effectively improving the efficiency of air flotation treatment.

[0020] 2. This utility model uses a second stepper motor to drive a second rotating shaft to rotate. The second rotating shaft drives one of the first rotating shafts to rotate in the same direction via a toothed belt, and drives the other first rotating shaft to rotate in the opposite direction via two gears. This causes the two baffles to rotate in the opposite direction. The angle between the two baffles can be adjusted as needed. When the connecting rope is pulled and the suspension box is moved in the sewage, the two baffles clean up leaves and other debris in the sewage. The structure is simple and easy to use.

The dissolved air box 2 is fixedly installed at the top of the suspension box 1. An air compressor 6 is fixedly connected to the rear side of the dissolved air box 2. A three-way hose 7 is fixedly connected to the output end of the air compressor 6. Air flotation release devices 8 are fixedly connected to both ends of the three-way hose 7. A moving component 3 is provided on the two air flotation release devices 8. The moving component 3 includes a first stepper motor 301, a lead screw 302, a slide bar 303, and a slide plate 304. The output shaft end of the first stepper motor 301 is fixedly connected to the lead screw 302. The bottom ends of the lead screw 302 and the slide bar 303 both penetrate the slide plate 304. The two air flotation release devices 8 are fixedly installed on the rear side of the slide plate 304.

[0030] Furthermore, a limiting ring 305 is fixedly sleeved at the bottom edge of the outer side of the lead screw 302 and the slide bar 303. A piston 5 is threadedly connected to the top of the dissolved gas tank 2. Control valves 9 are fixedly connected to the opposite side of the two air flotation releasers 8, and the two control valves 9 are fixedly installed on the three-way hose 7.

[0031] Furthermore, a support plate 10 is fixedly connected inside the suspension box 1, the first stepper motor 301 is fixedly installed on the top of the support plate 10, and the top of the slide rod 303 is fixedly connected to the support plate 10.

[0032] Furthermore, a guide assembly 4 is provided on the support plate 10. The guide assembly 4 includes two first rotating shafts 401, two baffles 402, a second rotating shaft 403, a toothed belt 404, a second stepper motor 405, and two gears 406. The top ends of the two first rotating shafts 401 are movably connected to the suspension box 1 through bearings, and the bottom end of the second rotating shaft 403 is movably connected to the support plate 10 through bearings. The top ends of the two baffles 402 are fixedly connected to the two first rotating shafts 401 respectively. One of the first rotating shafts 401 and the second rotating shaft 403 are connected through the toothed belt 404, and the other first rotating shaft 401 and the second rotating shaft 403 are connected through the two gears 406. The second stepper motor 405 is fixedly installed inside the top of the suspension box 1, and the output shaft end of the second stepper motor 405 is fixedly connected to the second rotating shaft 403.

[0033] The suspended tank 1 floats in the sewage and is connected to the dissolved air tank 2 by a connecting rope. The second stepper motor 405 is started, which drives the second rotating shaft 403 to rotate. The second rotating shaft 403 drives one of the first rotating shafts 401 to rotate in the same direction through a toothed belt 404, and drives the other first rotating shaft 401 to rotate in the opposite direction through two gears 406, thereby driving the two baffles 402 to rotate in the opposite direction.

When the connecting rope is pulled and the suspended tank 1 moves in the sewage, the two baffles 402 clean the leaves and other debris in the sewage. The structure is simple and easy to use.

[0034] The usage method of this embodiment is as follows:

[0035] In operation, the piston 5 is rotated away from the dissolved air tank 2, and raw water is added to the dissolved air tank 2. The air compressor 6 pressurizes and dissolves the air in the water, forming a supersaturated air solution. The dissolved air is then released as microbubbles through the two flotation releasers 8. Suspended solids in the wastewater adhere to the microbubbles and float to the surface under the action of buoyancy, forming a scum layer. At the same time, one of the control valves 9 is closed, preventing one of the flotation releasers 8 from releasing microbubbles. The first stepper motor 301 is started, which drives the lead screw 302 to rotate. Since the lead screw 302 is threadedly connected to the slide plate 304, and the slide bar 303 restricts the rotation of the slide plate 304, the lead screw 302 can drive the slide plate 304 to move downward, thereby driving the two flotation releasers 8 to move downward. The depth of the two flotation releasers 8 in the wastewater can be adjusted as needed. The operation is simple and convenient to adjust the depth of the two flotation releasers 8 in the water, effectively improving the efficiency of flotation treatment. At the same time, the two limit rings 305 can limit the downward movement distance of the slide plate 304.
