Description

Technical Field

[0001] This utility model relates to the field of air flotation machine technology, and in particular to leachate electrolytic air flotation machine. Background Technology

[0002] In landfill leachate treatment, dissolved air flotation (DAF) machines are used to separate solids from the leachate. A DAF machine uses small or microbubbles to float impurities to the surface. Currently, in water supply and drainage, the pre-treated water, apart from some raw water bodies with high sand content and wastewater containing heavy mechanical impurities, mostly contains light suspended particles. When this wastewater enters the DAF machine, gas is introduced from the outside, causing the bubbles to adhere to the flocs. The flocs then float to the surface with the bubbles, thus achieving rapid solid-liquid separation.

[0003] Patent document CN212476176U discloses an air flotation machine for treating oily landfill leachate, comprising a housing, an aeration device at one end of the housing, and a slag collection trough at the other end. A slag scraping device is located at the top of the housing to scrape slag into the slag collection trough. The aeration device includes an air tank, a stirring shaft, an air ring, and a drive component for rotating the stirring shaft. The stirring shaft is vertically oriented, and the drive component is fixed to the housing. Stirring blades are mounted on the stirring shaft. The air ring is an annular tube, fitted around the stirring shaft and located below the stirring blades. Ventilation holes are provided on the air ring, which communicates with the air tank. This invention increases the efficiency of bubble cutting and reduces bubble volume.

[0004] However, the above structure still has certain defects. When slag is scraped, its horizontal level will drop, resulting in poor performance in the next slag scraping.

[0005] Therefore, in order to solve the aforementioned technical problems, a leachate electrolysis flotation machine is needed. Utility Model Content

[0020] The embodiments of this utility model are described in detail below, with examples of the embodiments shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] The leachate electrolysis flotation machine of this utility model is described below with reference to the accompanying drawings.

[0022] like Figures 1 to 3 As shown, the leachate electrolysis flotation machine of this utility model embodiment may include a housing 1, a flocculation zone 2, a flotation zone 3, a collection zone 4, a mixing device 5, and a sludge scraping assembly 6.

[0023] The flocculation zone 2, the flotation zone 3 and the collection zone 4 are arranged sequentially in the working direction inside the box 1. The mixing device 5 is arranged in the flocculation zone 2. The slag scraping assembly 6 is arranged on the box 1, and the scraping end of the slag scraping assembly 6 is located in the flotation zone 3.

[0024] Preferably, pull rings (not shown in the figure) are provided on opposite sides of the housing 1, which facilitates the lifting of the pull rings by the staff using hoisting equipment, thereby lifting this utility model.

[0025] The mixing device 5 includes: a plate 51, a first drive motor 52, a guide rod 53, and a stirring rod 54.

[0026] Among them, a plate 51 is set at the top of the flocculation zone 2, a first drive motor 52 is set on the plate 51 through a mounting bracket, a guide rod 53 is axially set at the bottom of the plate 51, and the drive end of the first drive motor 52 passes through the plate 51 and is connected to the guide rod 53. Multiple stirring rods 54 are respectively set on the guide rod 53 and are respectively located in the flocculation zone 2.

[0027] The slag scraping assembly 6 includes a slag scraping device 61 and an adjusting device 62.

[0028] The slag scraping device 61 is installed on the housing 1, and the slag scraping end of the slag scraping device 61 is located in the air flotation zone 3. The adjusting device 62 is installed on the housing 1, and the adjusting end of the adjusting device 62 is connected to the connecting end of the slag scraping device 61.

[0029] The slag scraping device 61 includes: an inclined platform 611, a second plate 612, a transmission roller 613, a transmission belt 614, a scraper 615, and a second drive motor 616.

[0030] The inclined platform 611 is located at the bottom of the air flotation zone 3. Four transmission rollers 613 are respectively axially connected to the opposite sides of the two plates 612 and are located in the air flotation zone 3. The transmission belt 614 is sleeved on the four transmission rollers 613. Multiple scrapers 615 are respectively set on the outer wall of the transmission belt 614. The second drive motor 616 is set on one side of one of the plates 612 through the mounting bracket, and the drive end of the second drive motor 616 passes through the plate 612 and is connected to one of the transmission rollers 613.

[0031] It should be noted that the four transmission rollers 613 are arranged in a trapezoidal shape, and the hypotenuse of the trapezoid is parallel to the hypotenuse of the inclined platform 611, which facilitates the movement of multiple scrapers 615 along the hypotenuse of the inclined platform 611 in sequence.

[0032] In another possible embodiment of the present invention, multiple scrapers 615 are provided with filter holes (not shown in the figure) to facilitate the filtration of impurities in wastewater.

[0033] The adjusting device 62 includes: three plates 621, a rod 622, a drive cylinder 623, and a connecting ring 624.

[0034] Two three-plates 621 are respectively set on opposite sides of the housing 1, and inclined sliding holes 6211 are respectively opened on the opposite sides of the two three-plates 621, which are parallel to the inclined side of the inclined platform 611. One end of the two rods 622 are respectively set on opposite sides of the two two-plates 612, and the other end passes through the two sliding holes 6211 and extends. Two drive cylinders 623 are respectively set on opposite sides of the two three-plates 621 by mounting brackets. Two connecting rings 624 are respectively connected to the drive ends of the two rods 622 and the two drive cylinders 623.

[0035] It should be noted that the outer wall of rod 622 fits into the inner wall of sliding hole 6211, which effectively increases the stability of rod 622 and thus prevents it from shaking during operation.

[0036] Specifically, when this utility model is to be used, firstly, flocculant is added to the flocculation zone 2 and the first drive motor 52 is started. Multiple rotating stirring rods 54 are used to stir and coagulate the sewage impurities. The flocculated sewage enters the flotation zone 3. Microbubbles in the dissolved air water in the flotation zone 3 are adsorbed onto the surface of the flocs. Secondly, the second drive motor 616 is turned on and multiple moving scrapers 615 push the suspended matter floating on the water surface and make it fall into the collection zone 4.

[0037] It should be noted that when the second drive motor 616 is working, the drive end of the second drive motor 616 drives the connected transmission roller 613 to rotate, thereby driving the transmission belt 614 to rotate, and then driving multiple other transmission rollers 613 to rotate. At the same time, the transmission belt 614 drives multiple scrapers 615 to rotate, thereby pushing the suspended matter floating on the water surface.

[0038] It should be noted that when one of the scrapers 615 comes into contact with the surface of the inclined platform 611, the scraper 615 continues to move, thereby moving along the surface of the inclined platform 611 and pushing the suspended matter into the collection area 4.

[0039] When it is necessary to adjust the height between the scraper 615 and the water surface, the drive cylinder 623 is activated. The working end of the drive cylinder 623 drives the connecting ring 624 to move, and drives the rod 622 to slide along the sliding hole 6211, thereby driving the scraper device 61 to move, and then driving the scraper 615 to gradually approach the water surface.

[0040] In summary, the leachate electrolysis flotation machine according to the present invention, through the cooperation between the scraping device 61 and the adjusting device 62, facilitates the downward movement of the scraper 615 by the drive cylinder 623, thereby avoiding the situation where the water level drops and gradually moves away from the scraper 615 during long-term operation, thus reducing the scraping efficiency. Moreover, it is simple to operate and highly practical.
