Description

Technical Field

[0001] This utility model relates to the field of air flotation technology, specifically to an efficient air flotation device for separation. Background Technology

[0002] An air flotation machine is a highly efficient wastewater treatment device. It uses a microbubble generator to dissolve air into the wastewater instead of a traditional air-inducing device, causing impurities and organic matter in the wastewater to float to the surface with the microbubbles. Then, a scraper removes the waste residue from the surface, thereby achieving the purpose of wastewater purification.

[0003] According to the dissolved air flotation machine disclosed in Chinese Patent Publication No. CN216997990U, which relates to the field of dissolved air flotation technology, the device includes a housing. A flocculation zone is fixedly located at one end of the housing. One end of a rotating shaft is connected to a motor. A transmission mechanism is fixed between the motor and a stirring shaft. Both ends of the two rotating shafts are connected to conveyor belts via transmission wheels. Several mounting blocks are symmetrically fixed on the two conveyor belts. A scraper is movably inserted into a mounting groove, and a fixing mechanism that cooperates with the scraper is fixed within the mounting groove. This utility model has a reasonable structure. The transmission mechanism allows the motor to drive the rotating shaft while simultaneously causing the stirring shaft to rotate, effectively reducing the number of motors used, thus reducing energy consumption and saving production costs. Furthermore, the fixing mechanism facilitates quick installation and disassembly of the scraper and mounting groove without the need for tools, making it convenient for the scraper to be disassembled and replaced after prolonged use.

[0004] Currently, when existing air flotation machines scrape and convey foam, gaps exist between the scraper and the baffle during the foam lifting process. This causes some foam to flow away through the gaps, leaving some foam residue on the water surface, resulting in incomplete cleaning. Therefore, a high-efficiency separation air flotation device is proposed to solve the above-mentioned problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a highly efficient air flotation device to address the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a high-efficiency separation air flotation device, including an air flotation machine, a scraper mechanism provided on the air flotation machine, a partition plate fixedly connected inside the air flotation machine, and an arc-shaped guide plate fixedly connected on the partition plate;

[0007] The scraper mechanism includes a fixed plate and a motor. The motor is fixedly connected to the fixed plate. A rotating shaft is fixedly connected to the output end of the motor. A sprocket is fixedly connected to the rotating shaft. A chain is driven through the sprocket. A fixed frame is fixedly connected to the chain. A guide post is provided on the fixed frame. A mounting plate is fixedly connected to one end of the guide post. A scraper is fixedly connected to the mounting plate. A spring is sleeved on the guide post.

[0008] Preferably, the fixing plate is fixedly connected to the air flotation machine, the fixing frame is provided with guide holes, and the guide post passes through the interior of the guide hole. The setting of the guide post and the guide hole can limit the position of the mounting plate.

[0009] Preferably, a limiting block is fixedly connected to the other end of the guide post, one end of the spring abuts against the fixing frame, and the other end of the spring abuts against the mounting plate. The limiting block can prevent the guide post from detaching from the fixing frame.

[0010] Preferably, the air flotation machine has a drain outlet on its front side, a water inlet on its surface, and a drain outlet on its surface, so that foamy wastewater can be discharged through the drain outlet.

[0011] Preferably, the air flotation machine is equipped with a blower mechanism, which includes a fan. The fan is fixedly connected to the air flotation machine, and an air supply pipe is fixedly connected to the fan. The blower mechanism allows the foam on the water surface to be blown towards the arc-shaped guide plate.

[0012] Preferably, the air flotation machine is internally connected to an air duct, and the air outlet of the air duct is internally connected to a filter screen. The other end of the air supply pipe is connected to the air duct. The filter screen can prevent foreign objects from entering the interior of the air duct.

[0013] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0014] 1. This highly efficient air flotation device uses a motor to drive a rotating shaft, which in turn drives a chain via a sprocket. This causes a scraper to scrape and convey foam on the water surface inside the air flotation machine. When the scraper pushes the foam onto the arc-shaped guide plate, the scraper adheres to the guide plate due to the force of the spring, preventing gaps from causing some foam to flow away. When the scraper rises to a certain height, it will separate from the arc-shaped guide plate, thus guiding the foam into the chamber at the right end of the air flotation machine, improving the practicality of the air flotation device.

[0015] 2. This highly efficient air flotation device uses a blower to blow foam on the water surface inside the flotation machine towards the arc-shaped guide plate through its air duct. This, in turn, assists the scraper in pushing the foam, concentrating it on the right side of the water surface inside the flotation machine. This facilitates foam removal and further improves the practicality of the air flotation device. Attached Figure Description

For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" means two or more, unless otherwise explicitly specified.

[0027] Please see Figure 1-6 One embodiment of this utility model is: a high-efficiency separation air flotation device, including an air flotation machine 1, a scraper mechanism 2 provided on the air flotation machine 1, a partition 4 fixedly connected inside the air flotation machine 1, and an arc-shaped guide plate 5 fixedly connected on the partition 4.

[0028] The scraper mechanism 2 includes a fixed plate 201 and a motor 202. The motor 202 is fixedly connected to the fixed plate 201. A rotating shaft 203 is fixedly connected to the output end of the motor 202. A sprocket 204 is fixedly connected to the rotating shaft 203. A chain 205 is driven through the sprocket 204. A fixed frame 206 is fixedly connected to the chain 205. A guide post 209 is provided on the fixed frame 206. A mounting plate 208 is fixedly connected to one end of the guide post 209. A scraper 207 is fixedly connected to the mounting plate 208. A spring 210 is sleeved on the guide post 209. The motor 202 is started to drive the scraper. The rotating shaft 203 rotates, causing its sprocket 204 to drive the chain 205 for transmission. This allows the scraper 207 to scrape and convey the foam on the water surface inside the flotation machine 1. When the scraper 207 pushes the foam onto the arc-shaped guide plate 5, the scraper 207 will adhere to the arc-shaped guide plate 5 due to the force of the spring 210, preventing gaps from causing some foam to flow away. When the scraper 207 rises to a certain height, it will be offset from the arc-shaped guide plate 5, thereby guiding the foam into the right-end chamber inside the flotation machine 1, improving the practicality of the flotation device.

[0029] The fixing plate 201 is fixedly connected to the air flotation machine 1. The fixing frame 206 has a guide hole 211. The guide post 209 passes through the interior of the guide hole 211. The setting of the guide post 209 and the guide hole 211 can limit the position of the mounting plate 208.

[0030] The other end of the guide post 209 is fixedly connected to the limit block 212. One end of the spring 210 abuts against the fixing frame 206, and the other end of the spring 210 abuts against the mounting plate 208. The limit block 212 can prevent the guide post 209 from detaching from the fixing frame 206.

[0031] The air flotation machine 1 has a drain outlet 6 on its front side, a water inlet 7 on its surface, and a drain outlet 8 on its surface. The foamy wastewater can be discharged through the drain outlet 6.

[0032] Working principle: The motor 202 drives the shaft 203 to rotate, which in turn drives the chain 205 via the sprocket 204. This causes the scraper 207 to scrape and convey the foam on the water surface inside the flotation machine 1. When the scraper 207 pushes the foam onto the arc-shaped guide plate 5, the scraper 207 adheres to the arc-shaped guide plate 5 due to the force of the spring 210, preventing gaps from causing some foam to flow away. When the scraper 207 rises to a certain height, it will be offset from the arc-shaped guide plate 5, thus guiding the foam into the right-end chamber inside the flotation machine 1, improving the practicality of the flotation device.

[0033] Please see Figure 1-6Based on the above embodiments, in another embodiment of the present invention, the air flotation machine 1 is provided with a blower mechanism 3, which includes a blower 301. The blower 301 is fixedly connected to the air flotation machine 1, and an air supply pipe 302 is fixedly connected to the blower 301. The blower mechanism 3 is used to blow the foam on the water surface toward the arc-shaped guide plate 5.

[0034] The air flotation machine 1 is internally fixedly connected to an air duct 303. The air outlet of the air duct 303 is internally fixedly connected to a filter screen 304. The other end of the air supply pipe 302 is connected to the air duct 303. The filter screen 304 can prevent foreign objects from entering the interior of the air duct 303.

[0035] Working principle: By starting the blower 301, the air duct 303 blows the foam on the water surface inside the air flotation machine 1 towards the arc-shaped guide plate 5, thereby achieving the auxiliary scraper 207 to push the foam, so that the foam will be concentrated on the right side of the water surface inside the air flotation machine 1, which is convenient for foam removal and further improves the practicality of the air flotation device.

[0036] This utility model provides a highly efficient air flotation device for separation. There are many methods and approaches to implement this technical solution, and the above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model. All components not explicitly stated in this embodiment can be implemented using existing technology.
