Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment flotation machine. Background Art

[0002] Flotation machines are mainly divided into super-efficiency, horizontal flow and horizontal flow air flotation machines. The working principle of the air flotation machine is that the dissolved air system produces a large number of fine bubbles in the water, so that the air is attached to the particles in the form of highly dispersed tiny bubbles, resulting in a state where the density is less than that of water. The buoyancy principle is used to make the particles float on the water surface, thereby realizing the separation of solid into liquid. The air flotation machine is used in water supply, and.

The upper limit is fixed, and the specific surface area of ​​bubbles is small. The above factors limit the treatment rate of sewage treatment, but this method exists. In order to remove pollutants, flocculants are usually added before sewage is added to the flotation machine to make the pollutants flocculate into particles. Different flocculants are added to different sewage, and there is usually an antagonistic reaction. That is, if mixed together, it may cause the pollutants that have already formed particles to dissolve again. Therefore, usually one type of sewage can only be contained in one flotation machine, and each corresponding flotation machine also needs to be equipped with a corresponding scraper structure for scraping operations. However, the scraper of the scraping mechanism needs to be driven by a waterproof motor to move back and forth, resulting in each flotation machine needing to be equipped with a corresponding waterproof motor, thereby increasing the cost consumption.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0039] Specifically, the first motor 11 is turned on to drive the first gear 21 to rotate, which in turn drives the second gear 13 and the lifting sprocket 7 to rotate, thereby driving the arc scraper 3 to move and scrape off the pollutants.

[0040] Reference Figure 3 The air flotation assembly includes an air flotation device 14, a water storage tank 20 is provided inside the air flotation device 14, an air flotation generator 15 is installed on the inner bottom wall of the air flotation device 14, and the bottom wall of the air flotation device 14 is installed on the top wall of the right-angle frame 1;

[0041] Specifically, sewage is injected into the water storage tank 20, and microbubbles are generated by the flotation generator 15. The microbubbles adsorb suspended matter during their rising process, causing the suspended matter to float to the surface of the sewage. The model of the flotation generator 15 is a super-floating flotation generator 15, and its working principle is: the flotation generator 15 introduces compressed air or other gases at appropriate positions through a gas introduction system. The gas enters the water body in some way (such as a nozzle, an aerator or a blower), and a large number of tiny bubbles are formed at the contact point. The generated bubbles rise upward due to the buoyancy and adhere to the surface of pollutants such as suspended matter, grease and dissolved organic matter. The buoyancy of the bubbles causes the pollutants attached to the surface of the bubbles to rise to the liquid surface or above the liquid surface together, forming a floating foam layer.

[0042] Reference Figure 3 The material leakage component includes a funnel 10, the top wall of the funnel 10 is installed with an L-shaped rubber scraper 9, the bottom wall of the funnel 10 is connected with a material leakage pipe 19, and the left side of the funnel 10 is fixedly connected to the right side of the flotation device 14;

[0044] Reference Figure 3The feeding mechanism 2 includes a right-angle plate 209 and a connecting belt 204. The front side of the right-angle plate 209 is fixedly connected to a second motor 203. The output end of the second motor 203 passes through the right-angle plate 209 and is fixedly connected to a driving pulley 202. The right end of the rear side of the right-angle plate 209 is rotatably connected to a third rotating rod 208. The rear end of the third rotating rod 208 is fixedly connected to a driven pulley 207. The driven pulley 207 is connected to the driving pulley 202 through the connecting belt 204. A conveyor belt 201 is installed on the rear side of the driving pulley 202 and the driven pulley 207. A plurality of vertical plates 205 are equidistantly installed on the outer wall of the conveyor belt 201. A filter 206 is installed on the right side of the top wall of the right-angle frame 1.

The model of the filter 206 is a belt filter 206, and the working principle of the filter 206 is: the liquid or slurry mixture is evenly sprayed into the feeding area of ​​the belt filter 206 through the feeding system; the feeding area is provided with a cloth or mesh belt for supporting and transmitting the filter medium, and the mixture gradually enters the filtering area as the belt filter 206 moves; in the filtering area, the liquid part will pass through the filtering medium (usually a filter cloth or a filter screen), while the solid part will be retained on the filtering medium; the filtering medium plays the role of filtering and dehydrating. The solid particles are captured and a solid retention layer is formed, while the filtrate is allowed to pass through. After the filtration area is passed, a washing operation can be performed to remove the attached liquid in the solid retention layer. The washing water is applied to the solid layer by spraying or soaking, which helps to wash away the soluble substances attached to the solid particles, thereby increasing the dryness of the solid. After washing, it enters the pressing area. In the pressing area, the solid retention layer is further dehydrated by appropriate pressure. Rollers or drums are usually used to appropriately squeeze the solid retention layer to further discharge the retained liquid. The belt filter 206 continues to move, and eventually the dense solid retention layer is peeled off from the filter medium and discharged. The solid retention layer can be scraped off the filter medium by a scraper or brush and other devices, and then transported to the solid collection area. At this time, the filter medium is ready to enter the next cycle.
