Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an air flotation machine that is easy to clean. Background Technology

[0002] An air flotation machine is a water treatment device that uses a dissolved air system to generate a large number of microbubbles in water. This allows air to adhere to suspended particles in the form of highly dispersed microbubbles, creating a density less than that of water. By utilizing the principle of buoyancy, these particles float on the water surface, thus achieving solid-liquid separation.

[0003] For example, application number CN202222369393.6 relates to the technical field of sewage treatment, and in particular to a dissolved air flotation machine. Multiple sets of nozzles spray clean water onto the outer walls of the left and right sides of a scraper, washing away dirt adhering to the scraper surface and reducing secondary pollution of the water by the dirt adhering to the scraper. The machine includes a tank, a flocculation device, an aeration device, a water supply device, a flow guide, a conveyor belt, multiple sets of scrapers, a support, a water distribution tank, and multiple sets of nozzles. A drain outlet is provided at the bottom of the tank, an opening is provided at the right top of the tank, a flocculation device is provided at the left side of the tank, and a notch is provided at the upper right end of the tank. The flow guide is connected to the notch. The conveyor belt is installed on the upper inner wall of the tank and is located to the side of the notch. The conveyor belt rotates via a drive assembly. Multiple sets of scrapers are circumferentially installed on the outer walls of the conveyor belt. The support is installed on the upper outer wall of the tank. The top of the water distribution tank is connected to the inner wall of the support. The aeration device is connected to the lower outer wall of the tank.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problems of inconvenience in cleaning the scraper and the accumulation of dirt on its surface after prolonged use, which can easily fall back into the main body of the flotation machine and re-pollute the water after scraping, there are still limitations. During use, the scraper on the conveyor belt scrapes the foam on the water surface, and when the scraper removes the foam, it comes into contact with the water surface, causing the foam to be pushed back into the water, resulting in impurities falling back into the water.

[0023] like Figures 1 to 4 As shown, the present invention provides an easy-to-clean air flotation machine, including a housing 1, an inlet pipe 2, a drain pipe 3, an aeration pipe 4, and an aeration device 5.

An adjusting mechanism 11 is fixedly connected to the top of the adjusting plate 10. A collection box 12 is fixedly connected to the top of the right side of the housing 1.

[0024] refer to Figure 1 The adjustment mechanism 11 includes an adjustment cylinder 111, which is fixedly connected to the top of the adjustment plate 10. An adjustment rod 112 is provided on the right side of the mounting plate 6. The adjustment rod 112 is movably connected to the inside of the adjustment cylinder 111. Adjustment grooves 113 are provided on the front and rear sides of the inside of the housing 1. An adjustment plate 114 is movably connected inside the adjustment grooves 113. Transmission components 115 are provided on the front and rear sides of the top of the housing 1.

[0025] As a technical optimization of this utility model, by setting an adjustment mechanism 11, the adjustment plate 114 can rotate inside the adjustment groove 113 and drive the adjustment rod 112 to move and rotate. After the adjustment rod 112 moves and rotates, it can drive the adjustment plate 10 to rotate on the movable frame 9 through the adjustment cylinder 111, so that the airflow blown out of the ventilation groove 7 is guided by the adjustment plate 10.

[0026] refer to Figure 4The transmission assembly 115 includes a mounting groove 1151, which is connected to an adjustment groove 113. The mounting groove 1151 is located on the front and rear sides of the top of the housing 1. A motor 1152 is fixedly connected to the right side inside the mounting groove 1151. A screw 1153 is fixedly connected to the output end of the motor 1152. A threaded toothed plate 1154 is threadedly connected to the surface of the screw 1153. A gear 1155 is meshed at the bottom of the threaded toothed plate 1154. The outer side of the adjustment plate 114 is fixedly connected to the inner side of the gear 1155.

[0027] As a technical optimization of this utility model, by setting a transmission component 115, the motor 1152 inside the mounting groove 1151 can drive the screw 1153 to rotate after starting, and the screw 1153 can drive the threaded tooth plate 1154 to move after rotating, and the threaded tooth plate 1154 can drive the gear 1155 to rotate after moving, and the gear 1155 can drive the adjusting plate 114 to rotate after rotating.

[0028] refer to Figure 4 A support column 13 is fixedly connected to the outer side of the inner wall of the mounting groove 1151. The inner end of the support column 13 extends into the interior of the gear 1155 and is movably connected to the gear 1155.

[0029] As a technical optimization of this utility model, by setting a support column 13, the use of the support column 13 can support the gear 1155, so that the gear 1155 can rotate stably inside the mounting groove 1151.

[0030] refer to Figure 4 A frustum block 14 is movably embedded in the left side of the inner wall of the mounting groove 1151, and the right end of the frustum block 14 is fixedly connected to the left side of the screw 1153.

[0031] As a technical optimization of this utility model, by setting a frustum block 14, the use of the frustum block 14 can support the screw 1153, so that the screw 1153 can rotate stably and avoid the phenomenon of tilting when the screw 1153 rotates.

[0032] refer to Figure 4 The inner side of the threaded toothed plate 1154 is movably inlaid with balls 15, and there are several balls 15 distributed at equal intervals.

[0033] As a technical optimization of this utility model, by setting the ball 15, the use of the ball 15 can reduce the friction between the inner side of the threaded tooth plate 1154 and the inner wall of the mounting groove 1151, so that the threaded tooth plate 1154 can move stably inside the mounting groove 1151.

[0034] refer to Figure 4Guide strips 16 are fixedly connected to the front and rear sides of the bottom of the adjusting plate 10.

[0035] As a technical optimization of this utility model, by setting a guide bar 16, the use of the guide bar 16 can guide the airflow passing through the bottom of the adjusting plate 10, thereby guiding the airflow blown out of the ventilation slot 7.

[0036] The working principle and usage process of this utility model are as follows: During use, the air injection pipe 8 is connected to an external air pump, allowing airflow to pass through the air injection pipe 8 and into the ventilation slot 7 inside the mounting plate 6 when the air pump injects air into the pipe 8. Then, the motor 1152 inside the mounting slot 1151 is started, causing the motor 1152 to drive the screw 1153 to rotate. The rotation of the screw 1153 then moves the threaded toothed plate 1154 inside the mounting slot 1151, which in turn moves the gears on the surface of the support column 13. The gear 1155 rotates, causing the adjusting plate 114 inside the adjusting groove 113 to rotate. This causes the adjusting plate 114 to move the adjusting rod 112. The moving adjusting rod 112 then tilts the adjusting plate 10 on the movable frame 9 via the adjusting cylinder 111. This causes the airflow blowing out of the ventilation groove 7 to be blown diagonally downwards after passing through the tilted adjusting plate 10. The blowing airflow then blows the foam inside the box 1 into the collection box 12, thus achieving the effect of blowing and cleaning.

[0037] In summary, this easy-to-clean flotation machine, by setting up ventilation slots 7, allows the ventilation slots 7, in conjunction with the adjusting plate 10, to blow the foam inside the tank 1 into the collection tank 12. This solves the problem that during use, the foam on the water surface is scraped by a scraper on the conveyor belt, but when the scraper scrapes the foam, it comes into contact with the water surface and pushes the foam back into the water, causing impurities to fall back into the water, which has certain limitations.
