Description

Technical Field

[0001] The utility model relates to the technical field of air flotation machines, in particular to an air flotation machine for scraping suspended dirt. Background Technique

[0002] As a commonly used water treatment equipment, the air flotation machine is widely used in the fields of industrial wastewater treatment, domestic sewage treatment, and water purification. Its working principle is mainly to inject tiny bubbles into the water, so that solid particles or pollutants such as grease suspended in the water adhere to the bubbles, thereby realizing the rapid floating and separation of dirt. Traditional air flotation machines usually adopt a single-sided or single-station treatment method. Although this design can meet the basic sewage treatment requirements to a certain extent, there are obvious limitations in terms of treatment efficiency and treatment capacity.

[0003] The deficiencies of the existing air flotation machines are mainly reflected in the following aspects:

[0004] Limited treatment efficiency: Due to the limited treatment area of traditional single-sided or single-station air flotation machines, the treatment speed is slow, and it cannot meet the sewage treatment requirements of large-scale or high-load. Especially during peak hours or when treating high-concentration sewage, the treatment capacity of this design is significantly insufficient. Content of the Utility Model

[0006] In view of the deficiencies of the prior art, the utility model provides an air flotation machine for scraping suspended dirt to solve the above problems.

[0007] (II) Technical solutions

[0008] To achieve the above object, the utility model provides the following technical solution: An air flotation machine for scraping suspended dirt, including a processing tank distributed horizontally in a long strip shape. On both sides of the center of the processing tank, an inclined center partition plate is provided. The two center partition plates divide a U-shaped sewage inlet bin. On the left and right sides of the top of the processing tank, floating dirt conveyor belts are installed. On the outer belt surface of each floating dirt conveyor belt, a number of floating dirt pushing plates are evenly installed. At the left and right ends inside the processing tank, V-shaped dirt collection plates are installed. Inside both sides of the V-shaped dirt collection plates, feeding augers are installed.

[0026] Preferably, a bubble discharge pipe connected to an external air pump is installed at the bottom inside the treatment tank and between the two center partition plates.

[0027] Compared with the prior art, the present utility model provides a flotation machine for scraping suspended dirt, having the following beneficial effects:

[0028] Bilateral Symmetric Processing Improves Efficiency: This air flotation machine adopts a bilateral symmetric double-station sewage treatment operation. Through a synchronous drive mechanism, the synchronous operation of the floating sewage conveyor belts and feeding augers on both sides is ensured.

[0045] On the left and right ends inside the processing tank 1, there are respectively installed V-shaped dirt collection plates 3. Inside these V-shaped dirt collection plates 3, there is installed a feeding auger 5, which is used to convey the collected dirt out. On the front side outside the processing tank 1, there is installed a synchronous drive mechanism 6, which can drive the floating dirt conveyor belts 4 and the feeding auger 5 on both sides to run synchronously.

[0046] The specific structure of the synchronous drive mechanism 6 includes: a drive motor 61 installed at the center of the bottom of the front side of the processing tank 1; a drive gear 62 connected to the output end of the drive motor 61; a transmission gear 63 meshing with the top of the drive gear 62; and symmetrically distributed synchronous transmission components 64 on the left and right. These components are respectively docked with the rotation axes of the drive gear 62 and the transmission gear 63, and synchronously drive the floating dirt conveyor belt 4 and the feeding auger 5 on the same side, thereby ensuring the coordination and efficiency of the entire processing process.

[0047] The specific structure of the synchronous transmission component 64 includes: a drive shaft 645 and a fourth synchronous belt pulley 646 respectively docked with the drive shaft end of the floating dirt conveyor belt 4 and the front end of the feeding auger 5 on the same side; a third synchronous belt pulley 644 on the outer end of the drive shaft 645; a second synchronous belt 647 sleeved between the fourth synchronous belt pulley 646 and the third synchronous belt pulley 644; a second synchronous belt pulley 643 docked with the center of the outer side of the third synchronous belt pulley 644; a first synchronous belt 642 with one end sleeved on the second synchronous belt pulley 643; a first synchronous belt pulley 641 tensioned at the other end of the first synchronous belt 642; the first synchronous belt pulley 641 inside the left synchronous transmission component 64 is docked with the center of the drive gear 62; the first synchronous belt pulley 641 inside the right synchronous transmission component 64 is docked with the center of the transmission gear 63;

[0055] Introduce the sewage between the central partition plates 2 on both sides. The external air pump injects air bubbles into the bottom of the treatment tank 1 through the air bubble discharge pipe 7 to help the suspended contaminants float up and then spread from the center to both sides.

[0056] The floating contaminants are pushed by the floating contaminant pushing plates 41 on the floating contaminant conveyor belts 4 on both sides to the V-shaped contaminant collecting plate 3.

[0057] The feeding auger 5 operates inside the V-shaped contaminant collecting plate 3 to convey the collected contaminants out.

[0058] The collected contaminants are discharged through the floating contaminant discharge pipe 8.

[0059] The treated water flows back through the return pipe 9 for recycling or further treatment.
