Obviously, the described embodiments are only 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.

[0020] like Figure 1-Figure 3 As shown, a sewage flotation oil removal device comprises a shell 1; an input pipe 2 is fixedly connected to the side end of the shell 1; an air flotation chamber 8 is opened inside the shell 1; a motor 3 is fixedly connected to the inner wall of the air flotation chamber 8; a stirring blade 4 is fixedly connected to the output end of the motor 3; a No. 1 electric slide rail 5 is fixedly connected to the inner wall of the shell 1; a scraper 6 is slidably connected to the No. 1 electric slide rail 5; an oil removal unit is installed inside the shell 1; a collection box 7 is fixedly connected to the side end of the shell 1.

[0021] The sewage can be transported to the inside of the flotation chamber 8 through the input pipe 2, and then the flotation system of the shell 1 is turned on. At this time, the motor 3 is started, and the stirring blade 4 is rotated by the motor 3. The rotation of the stirring blade 4 can improve the flotation effect, so that the bubbles are mixed with the pollution, and then the grease in the sewage floats and moves to the right. After the work is completed, the water is extracted, and then the scraper 6 is slid by the No. 1 electric slide rail 5. The sliding of the scraper 6 can scrape the impurities precipitated at the bottom of the shell 1 to the collection box 7. The impurities are collected by the collection box 7, which is convenient for cleaning the impurities precipitated at the bottom of the shell 1 and improving the work efficiency.

[0022] The oil removal unit includes a No. 2 electric slide rail 11; the No. 2 electric slide rail 11 is fixedly connected to the inner wall of the shell 1; an oil scraper 12 is slidably connected to the No. 2 electric slide rail 11; a through hole 13 is opened inside the shell 1, and an oil scraper 12 is provided on one side of the through hole 13.

[0023] During the flotation process, the oil scraper blade 12 is made to slide by the No. 2 electric slide rail 11. The top of the oil scraper blade 12 is connected to a cylinder, which can move the oil scraper blade 12 up and down. When the No. 2 electric slide rail 11 makes the oil scraper blade 12 slide to scrape the grease on the water surface to the through hole 13 and enter the interior of the collection box 7, the cylinder moves the oil scraper blade 12 upward, and then returns to its original position through the No. 2 electric slide rail 11 and scrapes the grease into the interior of the collection box 7 for convenient unified treatment.

[0024] A sealing cover 14 is installed at the top of the shell 1; a connecting air pipe 15 is fixedly connected to the top of the sealing cover 14; a filter box 16 is fixedly connected to the side end of the connecting air pipe 15; a mounting plate 17 is installed inside the filter box 16; a filter cotton block 18 is fixedly connected to the bottom end of the mounting plate 17; and multiple groups of activated carbon 19 are fixedly connected inside the filter cotton block 18.

[0025] Before work, the sealing cover 14 is installed to the top of the shell 1 to seal the top of the shell 1. During the operation of the shell 1, odor will be generated, causing the odor to spread and seriously pollute the surrounding air. The side end of the filter box 16 is connected to an air pump, so that the connecting air pipe 15 absorbs the gas inside the shell 1 into the connecting air pipe 15. The filter cotton block 18 is made of filter cotton material. The gas entering the filter box 16 will be filtered by the filter cotton block 18. A plurality of groups of activated carbon 19 are arranged inside the filter cotton block 18. The activated carbon 19 can absorb impurities in the gas, thereby removing odor in the gas.

[0026] A purification block 20 is fixedly connected to the bottom end of the mounting plate 17 ; a plurality of air holes 21 are provided inside the purification block 20 , and a filter cotton block 18 is provided on one side of the air hole 21 .

[0027] A purification block 20 is installed inside the filter box 16. The gas is filtered by the filter cotton block 18 and enters the purification block 20. The gas flows from the inside of the pores 21. Multiple groups of aromatherapy blocks are installed inside the pores 21. The gas will be purified when it comes into contact with the aromatherapy blocks, thereby reducing the odor in the gas, and then discharged.

[0028] An electric push rod 9 is fixedly connected to the interior of the housing 1; a partition 10 is fixedly connected to the bottom end of the electric push rod 9, and a scraper 6 is provided on one side of the partition 10.

[0029] Before working, the scraper 6 slides the partition 10 upwards through the electric push rod 9. Only after the partition 10 is opened can the precipitated impurities be cleaned into the inside of the collection box 7 to prevent water from entering the inside of the collection box 7 through the partition 10 during flotation.

[0030] A magnet plate is fixedly connected to the bottom end of the sealing cover 14 ; and the bottom end of the magnet plate is connected to the housing 1 .

[0031] Before work, the sealing cover 14 is installed on the top of the housing 1. The sealing cover 14 is attracted to the housing 1 by the magnetic attraction of the magnet plate, and the sealing cover 14 is installed and removed on the housing 1 through the magnet plate.

[0032] The working principle of the utility model is as follows: before working, the sealing cover 14 is installed to the top of the shell 1, so as to seal the top of the shell 1. During the working process of the shell 1, odor will be generated, causing the odor to spread and seriously pollute the surrounding air. The side end of the filter box 16 is connected with an air pump, so that the connecting air pipe 15 absorbs the gas inside the shell 1 into the connecting air pipe 15. The filter cotton block 18 is made of filter cotton material. The gas entering the filter box 16 will be filtered by the filter cotton block 18. The filter cotton block 18 is provided with multiple groups of activated carbon 19. The activated carbon 19 can absorb impurities in the gas, thereby removing impurities in the gas. The filter box 16 is provided with a purification block 20 inside. The gas is filtered by the filter cotton block 18 and then enters the purification block 20. The gas flows from the inside of the air hole 21. There are multiple groups of aromatherapy blocks installed inside the air hole 21. The gas is purified by the aromatherapy blocks, thereby reducing the odor in the gas, and then discharged. Before work, the sealing cover 14 is installed to the top of the shell 1. The sealing cover 14 is attracted to the shell 1 by the magnetic attraction of the magnet plate. The sealing cover 14 is installed and removed from the shell 1 through the magnet plate. The sewage can be transported to the inside of the air flotation chamber 8 through the input pipe 2, and then the gas is opened. The air flotation system of the shell 1 is turned on, and the motor 3 is started at this time. The stirring blade 4 is rotated by the motor 3. The rotation of the stirring blade 4 can improve the air flotation effect, so that the bubbles are mixed with the pollution, and then the grease in the sewage floats and moves to the right. After the work is completed, the water is extracted, and then the scraper 6 is slid by the No. 1 electric slide rail 5. The sliding of the scraper 6 can scrape the impurities precipitated at the bottom of the shell 1 to the collection box 7. The impurities are collected by the collection box 7, which is convenient for cleaning the impurities precipitated at the bottom of the shell 1 and improving the work efficiency; before the scraper 6 works, the electric push rod 9 makes the partition 10 slide upward, and the partition 1 0 can be opened to clean the precipitated impurities into the collection box 7 to prevent water from entering the collection box 7 from the partition 10 during flotation; during the flotation process, the oil scraper 12 is slid by the No. 2 electric slide 11, and the top of the oil scraper 12 is connected to a cylinder, which can move the oil scraper 12 up and down. When the No. 2 electric slide 11 makes the oil scraper 12 slide to scrape the grease on the water surface to the through hole 13 to enter the collection box 7, the cylinder moves the oil scraper 12 upward, and then returns to its original position through the No. 2 electric slide 11 and scrapes the grease into the collection box 7, which is convenient for unified treatment.
