[0029] Reference Figure 1-6 ,

[0030] A flotation purification device includes: a sedimentation tank 1, an aerator 2, a scraper 3, a drive 4, and a collection tank 5. The aerator 2 is located at the bottom of the sedimentation tank 1. The scraper 3 has a scraping portion, which is the end of the scraper 3 and is thinner than the normal thickness of the scraper 3. The sedimentation tank 1 contains liquid to be treated. The liquid contains impurities. The aerator 2 is used to aerate the bottom of the sedimentation tank 1. The impurities in the liquid in the sedimentation tank 1 rapidly float upward due to the aeration, resulting in a certain thickness of impurities accumulating on the liquid surface of the sedimentation tank 1. The scraper 3 contacts the liquid surface of the sedimentation tank 1, and the drive 4 is used to drive the scraper 3 to move in a predetermined direction on the liquid surface of the sedimentation tank 1. As the scraper 3 moves, it scrapes away impurities on the liquid surface, more precisely, it gathers impurities from one location in the sedimentation tank 1 to another. The collection tank 5 is located at the edge of the sedimentation tank 1 so that the scraper 3 can scrape impurities from the liquid surface of the sedimentation tank 1 into the collection tank 5. Thus, the dirt is discharged outward, and the sewage in the sedimentation tank 1 is preliminarily treated. In this solution, the liquid surface preferably matches the upper surface of the sedimentation tank 1, so that when the scraper 3 moves, the scraping part can directly scrape the dirt away from the sedimentation tank 1, so that the dirt falls into the collection box 5.

[0031] Specifically, two groups of the collecting boxes 5 are provided, and the two groups of the collecting boxes 5 are provided on both sides of the sedimentation tank 1. The collecting boxes 5 are distributed on both sides of the sedimentation tank 1 along the preset direction. The driving member 4 is used to drive the scraping portion to move back and forth between the two groups of the collecting boxes 5. Therefore, in the process of the reciprocating movement of the scraper 3, from one end of the sedimentation tank 1 to the other end, part of the stains will be scraped into one of the collecting boxes 5. Conversely, when the scraper 3 is reset, the stains on the liquid surface will be scraped into the other collecting box 5. In this way, the reset process of the scraper 3 can be utilized, and the stains on the liquid surface can be scraped off at a high frequency.

[0032] More specifically, the scraper 3 has two scraping portions, one at the upper end and the other at the lower end of the scraper 3. The scraper portion at the upper end is defined as the upper scraping portion 31, and the scraper portion at the lower end is defined as the lower scraping portion 32. The driving member 4 is also used to drive the scraper 3 to move upward, downward, and rotate. The driving member 4 drives the scraper 3 to rotate so that the upper scraping portion 31 or the lower scraping portion 32 contacts the liquid surface of the sedimentation tank 1. When the scraper 3 moves in the preset direction, the lower scraping portion 32 contacts the liquid surface of the sedimentation tank 1; when the scraper 3 moves away from the preset direction, the upper scraping portion 31 contacts the liquid surface of the sedimentation tank 1.

[0033] The driving member 4 includes: a guide rail 41, a slider, a mobile frame, a first driving structure 42, a second driving structure 43, a rotating driving structure 44 and a lifting frame 45. The guide rail 41 is fixedly arranged above the sedimentation tank 1, the slider is slidably connected to the guide rail 41, and the mobile frame is fixed to the slider. The first driving structure 42 is used to drive the mobile frame to move. The second driving structure 43 is installed on the mobile frame, and the lifting frame 45 is connected to the second driving structure 43, and the second driving structure 43 is used to drive the lifting frame 45 to move. The rotating driving structure 44 is fixed to the lifting frame 45, and the output end of the rotating driving structure 44 is connected to the scraper 3, and the rotating driving structure 44 is used to drive the scraper 3 to rotate.

[0034] The working process is as follows: the first drive structure 42 drives the movable frame to move from one end of the sedimentation tank 1 to the other end. Then the second drive structure 43 drives the lifting frame 45 to move upward, the rotary drive structure 44 drives the scraper 3 to rotate half a circle, the second drive structure 43 drives the lifting frame 45 to move downward and reset, and the first drive structure 42 drives the movable frame to reset.

[0035] The first drive structure 42 and the second drive structure 43 are each configured to be one of a pneumatic cylinder, a hydraulic cylinder, and a screw-nut pair. The rotation drive structure 44 is preferably configured to be a drive motor.

[0036] In other embodiments, a cleaning member 6 is provided on the scraper 3. The cleaning member 6 is used to clean the upper scraper 31 when the lower scraper 32 contacts the liquid surface of the sedimentation tank 1; and is used to clean the lower scraper 32 when the upper scraper 31 contacts the liquid surface of the sedimentation tank 1. In this embodiment, the cleaning member 6 comprises an air pipe 61 and an air pump 62. The air pipe 61 is provided in the middle of the scraper 3 and has two air outlets, one of which is used to blow air onto the upper scraper 31 and the other is used to blow air onto the lower scraper 32. A control valve is provided between the two air outlets to control the air outlet from one of the two outlets. The air pipe 61 is connected to the air pump 62. The cleaning member 6 is provided in the middle of the scraper 3; the axis of rotation of the scraper 3 is located in the middle of the scraper 3. Preferably, after the air pipe 61 is inserted into the scraper 3, it extends outward from the scraper 3.

[0037] In other embodiments, when the scraper 3 moves to the edge of the sedimentation tank 1, the driving member 4 rotates the scraper 3 until the scraper 3 is at least partially located above the collection box 5. When the scraper 3 is partially located above the collection box 5, the cleaning member 6 cleans the upper scraping portion 31 or the lower scraping portion 32. When the driving member 4 drives the scraper 3 to rotate 90°, the scraper 3 is partially located above the cleaning member 6.

[0038] The above description is only an illustration of some preferred embodiments of the present disclosure and the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept. For example, the above-mentioned features are replaced with (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure.
