Description

Technical Field

[0001] This utility model relates to the technical field of ozone flotation, and in particular to an ozone flotation device for combined sewer overflow sewage. Background Technology

[0002] Ozone flotation is a powerful technical means to degrade typical CSO pollutants and can adapt to the complex and variable situation of combined sewer overflow pollution of water quality and quantity.

[0003] Among existing ozone flotation devices for combined sewer overflows, such as the one disclosed in utility model patent application number 202320194683.3, this utility model breaks through the limitations of traditional devices on dissolved gas volume, greatly improving ozone mass transfer efficiency and simultaneously enhancing the effects of ozone microbubble oxidation and coagulation flotation. It utilizes active oxygen free radicals generated by catalytic oxidation to non-selectively oxidize recalcitrant organic matter, enhancing the removal effect of organic matter and greatly improving the treatment efficiency of the device, while also increasing the utilization rate of ozone. This skid-mounted device can achieve rapid and efficient treatment of combined sewer overflow pollution, possessing advantages such as good treatment effect, resistance to shock loads, no permanent land occupation, easy mobility and scheduling, flexible operation mode, convenient operation and management, and excellent applicability. It can be industrialized and has good engineering application prospects.

[0004] However, during ozone flotation, it is not easy to clean up impurities floating on the surface of the material by simply removing them, and foamy impurities adhere to the equipment and are not easy to clean. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an ozone flotation device for combined overflow sewage, which, by setting up a scraping mechanism and a rinsing mechanism, can more thoroughly clean impurities on the liquid surface during the ozone flotation process and can also rinse the equipment to reduce the adhesion of impurities to the equipment.

[0006] This utility model discloses an ozone flotation device for combined overflow sewage, including an aeration mechanism; it also includes a filtration mechanism, a drive mechanism, multiple scraping mechanisms and a flushing mechanism. The filtration mechanism is installed at the right end of the aeration mechanism, the drive mechanism is installed on the aeration mechanism, the multiple scraping mechanisms are installed on the drive mechanism, and the flushing mechanism is installed at the right end of the filtration mechanism.

[0007] The aeration mechanism performs aeration, the filtration mechanism performs filtration, the drive mechanism performs actuation, the scraping mechanism performs scraping, and the rinsing mechanism performs rinsing. By opening the aeration mechanism, impurities in the material are separated; by opening the drive mechanism, the scraping mechanism is driven, and the scraping mechanism scrapes off impurities from the liquid surface; by opening the rinsing mechanism, the scraping mechanism is rinsed, and the rinsing water from the scraping mechanism is poured into the filtration mechanism for further filtration. This allows for a more thorough cleaning of impurities from the liquid surface during ozone flotation and also rinses the equipment, reducing the adhesion of impurities to the equipment.

[0008] Preferably, the aeration mechanism includes a liquid tank, an air pump, and an aeration pipe. The air pump is installed at the left end of the liquid tank, the aeration pipe is installed inside the liquid tank, and the input end of the aeration pipe is connected to the output end of the air pump. By turning on the air pump, aeration is carried out through the aeration pipe, causing impurities in the liquid to adhere to tiny bubbles and float to the surface.

[0009] Preferably, the filtration mechanism includes a filter chamber and a filter screen. The filter chamber is installed at the right end of the liquid tank, and the filter screen is slidably installed inside the filter chamber. The rinsing water poured out by the scraping mechanism is filtered through the filter screen.

[0010] Preferably, the drive mechanism includes two sets of sprocket shafts, two sets of chains, and a motor. The two sets of sprocket shafts are rotatably installed inside the liquid tank, and the two sets of chains are wrapped around the two sets of sprocket shafts. The motor is installed at the front end of the liquid tank, and the output end of the motor is connected to the input end of one set of sprocket shafts. By turning on the motor, the sprocket shafts are driven to rotate, and the rotation of the sprocket shafts is coordinated with the chain to make the chain rotate.

[0011] Preferably, the scraping mechanism includes a mounting plate, a scraping scoop, a screen, and multiple sets of baffles. The mounting plate is mounted on two sets of chains, the scraping scoop is rotatably mounted on the mounting plate, the screen is mounted on the scraping scoop, and the multiple sets of baffles are rotatably mounted on the scraping scoop. The rotation of the chains drives the mounting plate to move, thereby causing the mounting plate to move the scraping scoop. As the scraping scoop moves, it collects impurities from the liquid surface. At the same time, the liquid surface impacts the baffles, causing the baffles to open and release impurities and the mixture. When the scraping scoop moves to the tipping position, it filters the liquid through the screen, and the remaining impurities are stored in the scraping scoop.

[0012] Preferably, the rinsing mechanism includes a pump, a nozzle, and a water pipe. The pump is installed at the right end of the filter compartment, the nozzle is installed inside the filter compartment, and the output end of the pump and the input end of the nozzle are connected through a water pipe. By turning on the pump, the scraping mechanism is rinsed through the water pipe and the nozzle, so that the impurities in the scraping spoon are poured into the filter compartment.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by opening the aeration mechanism to separate impurities in the material, by opening the drive mechanism to drive the scraping mechanism, by scraping the impurities on the liquid surface by the scraping mechanism, by opening the rinsing mechanism to rinse the scraping mechanism, and by pouring the rinsing water in the scraping mechanism into the filtration mechanism for filtration, the impurities on the liquid surface can be cleaned more thoroughly during the ozone flotation process, and the equipment can be rinsed to reduce the adhesion of impurities to the equipment.

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0020] Example 1

[0021] like Figures 1 to 4 As shown, an ozone flotation device for combined overflow sewage includes an aeration mechanism 1, a filtration mechanism 2, a drive mechanism 3, multiple scraping mechanisms 4, and a flushing mechanism 5. The filtration mechanism 2 is installed at the right end of the aeration mechanism 1, the drive mechanism 3 is installed on the aeration mechanism 1, the multiple scraping mechanisms 4 are installed on the drive mechanism 3, and the flushing mechanism 5 is installed at the right end of the filtration mechanism 2.

[0022] The aeration mechanism 1 performs aeration, the filtration mechanism 2 performs filtration, the driving mechanism 3 performs driving, the scraping mechanism 4 performs scraping, and the rinsing mechanism 5 performs rinsing.

[0023] The aeration mechanism 1 includes a liquid tank 11, an air pump 12 and an aeration pipe 13. The air pump 12 is installed at the left end of the liquid tank 11, and the aeration pipe 13 is installed inside the liquid tank 11. The input end of the aeration pipe 13 is connected to the output end of the air pump 12.

[0024] The filtration mechanism 2 includes a filter chamber 21 and a filter screen 22. The filter chamber 21 is installed at the right end of the liquid tank 11, and the filter screen 22 is slidably installed inside the filter chamber 21.

[0025] The drive mechanism 3 includes two sets of sprocket shafts 31, two sets of chains 32 and a motor 33. The two sets of sprocket shafts 31 are rotatably installed inside the liquid tank 11, and the two sets of chains 32 are wrapped around the two sets of sprocket shafts 31. The motor 33 is installed at the front end of the liquid tank 11, and the output end of the motor 33 is connected to the input end of one set of sprocket shafts 31.

[0026] The scraping mechanism 4 includes a mounting plate 41, a scraping spoon 42, a screen 43, and multiple sets of baffles 44. The mounting plate 41 is mounted on two sets of chains 32. The scraping spoon 42 is rotatably mounted on the mounting plate 41. The screen 43 is mounted on the scraping spoon 42. The multiple sets of baffles 44 are rotatably mounted on the scraping spoon 42.

[0027] The rinsing mechanism 5 includes a pump 51, a nozzle 52 and a water pipe 53. The pump 51 is installed at the right end of the filter chamber 21, the nozzle 52 is installed inside the filter chamber 21, and the output end of the pump 51 and the input end of the nozzle 52 are connected through the water pipe 53.

[0028] By turning on the air pump 12 and aerating the liquid through the aeration pipe 13, impurities in the liquid adhere to tiny bubbles and float to the surface. Turning on the motor 33 drives the sprocket shaft 31 to rotate. Simultaneously, the chain 32 rotates, causing the mounting plate 41 to move. This movement, in turn, moves the scraper 42, which collects impurities from the liquid surface. Simultaneously, the liquid surface impacts the baffle 44, causing it to open and allow impurities to escape. The liquid and mixture are released. When the scraper 42 moves to the flip position, the liquid is filtered through the screen 43. The remaining impurities are stored in the scraper 42. By turning on the pump 51, the scraper mechanism 4 is flushed through the water pipe 53 and the nozzle 52, so that the impurities in the scraper 42 are poured into the filter chamber 21. The flushing water poured out by the scraper mechanism 4 is filtered through the filter screen 22. Thus, during the ozone flotation process, the impurities on the liquid surface can be cleaned more thoroughly, and the equipment can be rinsed to reduce the adhesion of impurities to the equipment.

[0029] like Figures 1 to 4As shown, this utility model discloses an ozone flotation device for combined sewer overflow sewage. During operation, the air pump 12 aerates the liquid via the aeration pipe 13, causing impurities in the liquid to adhere to tiny bubbles and float to the surface. The motor 33 drives the sprocket shaft 31 to rotate, and the chain 32 rotates simultaneously. This chain rotation moves the mounting plate 41, which in turn moves the scraper 42. As the scraper 42 moves, it collects impurities from the liquid surface. Simultaneously, the liquid impacts the baffle 44, causing it to open and allowing the impurities and mixture to pass through. When the scraper 42 moves to the tipping point, it filters the liquid through the screen 43. The remaining impurities are stored in the scraper 42. By turning on the pump 51, the scraping mechanism 4 is flushed through the water pipe 53 and the nozzle 52, causing the impurities in the scraper 42 to be poured into the filter chamber 21. The flushing water poured out by the scraping mechanism 4 is filtered through the filter screen 22.

[0030] The air pump 12, motor 33 and pump 51 of this utility model are purchased from the market. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0031] The main function achieved by this utility model is: during the ozone flotation process, by setting up a scraping mechanism and a rinsing mechanism, impurities on the liquid surface can be cleaned more thoroughly during the ozone flotation process, and the equipment can be rinsed to reduce the adhesion of impurities to the equipment.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
