DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The present utility model will be further described in detail below in conjunction with the drawings and specific embodiments. The embodiments of the present utility model are given for the purpose of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and design various embodiments with various modifications suitable for specific purposes.

[0018] Please refer to Figures 1 to 5, in this embodiment, a sludge air flotation concentration device is provided, including a processing tank 1 and a top plate 2. It is characterized in that an air inlet is installed on the front end face inside the processing tank 1, and a dissolved air release device 11 is installed at the other end of the air inlet. A water inlet pipe 12 is installed on the upper end face of the dissolved air release device 11. A top plate 2 is arranged inside the processing tank 1. A fixed cavity 13 is installed on the right end face of the processing tank 1. A regulating lead screw 14 is rotatably installed on the front end face inside the fixed cavity 13 through a bearing. A regulating motor 15 is installed on the rear end face of the regulating lead screw 14. Regulating sliders are symmetrically installed on the front and rear outer side walls of the regulating lead screw 14. A side plate 16 is installed on the upper end face of the regulating slider. A base table is installed on the right end face of the processing tank 1. A regulating cylinder 17 is installed on the upper end face of the base table. A push plate 18 is installed at the output end of the regulating cylinder 17. Scraping knives 19 are symmetrically installed on the front and rear end faces of the push plate 18. During operation, sludge enters the processing tank 1, and the dissolved air water enters the dissolved air release device 11 through the water inlet pipe 12. The dissolved air release device 11 forms bubbles and enters the processing tank 1 through the air inlet pipe, mixes with the sludge to form flocs, floats to the bottom of the top plate 2 to form a scum layer. The top plate 2 rotates 180 degrees, and the regulating motor 15 is started to drive the regulating lead screw 14 to rotate, causing the side plate 16 to move inwards, thereby gathering the scum layer. Subsequently, the regulating cylinder 17 is started to drive the push plate 18 to move leftward to push the scum layer, ensuring the cleaning effect on the surface of the push plate 18 and avoiding waste of the scum layer. The scraping knives 19 clean the scum layer adhered to the inner side end of the side plate 16.

[0019] A main shaft is rotatably installed on the front end face inside the processing tank 1 through a bearing. A top plate 2 is installed on the outer side wall of the main shaft. A first motor 21 is installed on the rear end face of the main shaft. A side frame is installed on the left end face of the processing tank 1. A recovery cavity 22 is installed at the bottom inside the side frame. During operation, the first motor 21 is started to drive the main shaft to rotate, causing the top plate 2 to turn over. When the push plate 18 moves leftward, the scum layer is pushed into the recovery cavity 22 for collection.

[0020] A second motor 23 is arranged above the recovery cavity 22. A regulating cam 24 is installed at the output end of the second motor 23. A pressing plate is arranged below the regulating cam 24. First springs 25 are symmetrically installed on the front and rear bottom of the pressing plate. The other end of the first spring 25 is installed on the upper end face of the side frame. A spring rod 27 is installed on the bottom of the pressing plate. A scraping plate 26 is installed at the bottom of the spring rod 27. During operation, the second motor 23 is started to drive the regulating cam 24 to rotate. The regulating cam 24 presses the pressing plate, causing the scraping plate 26 to move downward to scrape and clean the left end face of the push plate 18, avoiding waste. The first spring 25 plays a role in resetting the pressing plate, and the spring rod 27 drives the push plate 18 to vibrate up and down, thereby further improving the cleaning effect on the push plate 18.

[0021] During specific operation, sludge enters the processing tank 1, and the dissolved air water enters the dissolved air release device 11 through the water inlet pipe 12. The dissolved air release device 11 forms bubbles that enter the processing tank 1 through the air inlet pipe, mix with the sludge to form flocs, float to the bottom of the top plate 2 to form a scum layer. The top plate 2 rotates 180 degrees, the adjustment motor 15 starts, drives the adjustment lead screw 14 to rotate, so that the side plate 16 moves inwards, thereby gathering the scum layer. Subsequently, the adjustment cylinder 17 starts, drives the push plate 18 to move left to push the scum layer, ensuring the cleaning effect on the surface of the push plate 18 and avoiding waste of the scum layer. The scraper 19 cleans the scum layer adhered to the inner end of the side plate 16.
