[0002] Food wastewater treatment is a method for purifying wastewater discharged during food industry production. This type of wastewater has a complex composition due to the variety of raw materials used, and its main pollutants include suspended solids, grease, dissolved organic matter, and pathogens. It is characterized by high organic content and easy spoilage, and improper treatment can easily lead to eutrophication of water bodies. In the process of food production wastewater treatment, in order to achieve solid-liquid separation and thus treat the pollutants in the wastewater, dissolved air flotation tanks are used to generate scum from the wastewater.

[0003] In existing dissolved air flotation (DAF) tanks, scum generated on the water surface is scraped off by a circulating scraper. However, the scraper's operation is not always reliable in removing scum, and prolonged use can lead to residual scum on the surface, reducing the effectiveness of subsequent circulation. Therefore, a scum scraping device for DAF treatment of food production wastewater is proposed to address these issues. Utility Model Content

[0006] The other end of the connecting block is provided with a fixing box, and a first servo motor is provided in the fixing box. The first servo motor is provided with an output shaft, and a rotating block is inserted into another set of fixing boxes on one side of the output shaft. A scraper is provided between the output shaft and the rotating block.

[0007] The fixed frame is provided with slag receiving boxes at both ends on the outer wall of the flotation tank, and each slag receiving box is provided with a material receiving plate.

The fixed frame is provided with a second servo motor at both ends, and one end of the output shaft of the second servo motor is connected to a rotating shaft through a coupling. The rotating shaft is provided with a spray arm on the outer wall, and multiple sets of nozzles are evenly provided on the lower end face of the spray arm. A water inlet pipe is provided on the spray arm, and the other end of the water inlet pipe is connected to a water source through a water pump.

It should be noted that the fixed frame 2 of this device is installed on the mounting frame near the air flotation tank 1 according to the actual situation, so as to ensure that the transmission chain 3 can work normally.

[0020] Furthermore, under the action of the motor, the connecting rod 4 forms a transmission structure through the output shaft, driven wheel and fixed frame 2, thereby driving the scraper 8 assembly to move in a cycle through the transmission chain 3, thereby scraping off the scum in the flotation tank 1 through the scraper 8.

[0021] The transmission chain 3 has multiple sets of connecting rods 4 on its outer wall, and a fixing rod 5 is provided at one end of the connecting rod 4. Multiple sets of spiral holes are opened on the fixing rod 5, and sliding grooves are opened on the opposite side of the fixing rod 5. Connecting blocks are inserted in the sliding grooves, and bolts are inserted in the connecting blocks and spiral holes. A nut is screwed on the other end of the bolt.

[0022] Furthermore, the first servo motor 7 forms a sliding structure with the fixed rod 5 via a connecting block, and the connecting block forms a spiral locking structure with the fixed rod 5 via bolts 6 and nuts, thereby facilitating the adjustment of the position of the scraper 8 according to the thickness of the scum layer in the flotation tank 1, so as to ensure the scraping effect of the scraper 8 on the scum.

[0023] The other end of the connecting block is provided with a fixing box, and the fixing box is provided with a first servo motor 7. The first servo motor 7 is provided with an output shaft, and a rotating block is inserted into another fixing box on one side of the output shaft. A scraper 8 is provided between the output shaft and the rotating block.

[0024] Furthermore, the scraper 8 has an L-shaped structure, and under the action of the first servo motor 7, the scraper 8 forms a rotating structure with the fixed rod 5 through the rotating block. Thus, the rotatable scraper 8 can be circulated while facilitating the cleaning of residual scum on its surface.

[0025] The fixed frame 2 has slag receiving boxes 9 at both ends on the outer wall of the flotation tank 1, and each slag receiving box 9 has a receiving plate 10 inside. One side of the receiving plate 10 has an opening on the slag receiving box 9. The fixed frame 2 has second servo motors 11 at both ends, and one end of the output shaft of the second servo motor 11 is connected to a rotating shaft 12 via a coupling. The rotating shaft 12 has a spray arm on its outer wall, and multiple sets of nozzles 13 are evenly distributed on the lower end face of the spray arm. A water inlet pipe is provided on the spray arm, and the other end of the water inlet pipe is connected to a water source via a water pump. It should be further noted that this utility model is... A slag scraping device for air flotation treatment of food production wastewater comprises standard parts or parts known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. All electrical components mentioned above in this device refer to power components, electrical components, and the matching monitoring computer and power supply, which are connected by wires. The specific connection method should refer to the working principle described above, and the electrical connection between each electrical component should be completed in the order of operation. The detailed connection method is a well-known technology in the field.

[0026] Furthermore, under the action of the second servo motor 11, the nozzle 13 forms a rotating structure with the fixed frame 2 through the rotating shaft 12, so that the rotatable nozzle 13 can easily wash the scum inside the scraper 8 and the scum receiving box 9, thereby ensuring the scraping effect of the scraper 8 on the scum in the future.

[0027] Working Principle: When using the scum scraping equipment for food production wastewater flotation treatment, the wastewater is first placed into the flotation tank 1. Air is introduced into the water or a large number of microbubbles are generated. These bubbles rise along with suspended particles in the water, forming a scum layer on the surface. During the scum layer treatment process in the flotation tank 1, the position of the scraper 8 needs to be adjusted according to the thickness of the scum layer. After adjusting the scraper 8 to the appropriate position using the connecting block, it is screwed in place using bolts 6 and nuts. Then, the servo motor in the fixed frame 2 can be started, so that the scraper 8 is driven to move cyclically via the moving transmission chain 3, thereby scraping away the scum on the water surface. The L-shaped scraper 8 further enhances the scum removal effect. When the scraper 8 moves above the scum receiving box 9 on the right end of the fixed frame 2, the system can be activated. The first servo motor 7 is activated to drive the scraper 8 to rotate so that the scum falls into the scum collection box 9. At the same time, the water pump can be started to wash the scum attached to the scraper 8 through the nozzle 13, so as to ensure that the scum can be flushed into the scum collection box 9 for collection and treatment. This also ensures that the scraper 8 can work continuously. When the scraper 8 moves to the scum collection box 9 at the left end of the fixed frame 2, its surface can be further washed by the nozzle 13 to ensure the cleanliness of the scraper 8 surface and thus ensure the subsequent cycle work effect of the scraper 8. During the operation, the second servo motor 11 can be started to drive the nozzle 13 to rotate through the rotating shaft 12 so that the scraper 8 and the scum collection box 9 can be cleaned periodically by the nozzle 13. This is the operation process of the scum scraping equipment for the air flotation treatment of food production wastewater.
