Description

[0002] In the process of sewage treatment, the air flotation machine is one of the commonly used equipment. Its main function is to inject bubbles into the sewage, so that the suspended particles in the sewage adhere to the bubbles and float to the water surface with the bubbles to form a scum layer, thereby realizing the solid-liquid separation.

[0003] However, there are many problems in the actual operation of the existing shallow air flotation machines. For example, the cleaning and discharging of the scum are generally driven by a combination of multiple driving sources, which will increase the cost of the equipment and reduce its reliability. Moreover, there is no effective automatic mechanism for collecting newly generated scum. Therefore, during the process of the scraper resetting, the scum will be pushed onto the side wall of the housing of the air flotation machine body, increasing the subsequent cleaning difficulty and affecting the continuity and efficiency of the entire sewage treatment process.

[0048] The air flotation machine body 1 is further installed with a driving component. The driving component includes an adjusting roller 2 for driving the scum cleaning component to slide. A lifting block 253 is installed at the center of the adjusting roller 2. A telescopic component is installed on the cleaning frame 3. The telescopic component is slidably connected to the upper surface of the adjusting roller 2. After the telescopic component follows the scum cleaning component and slides to the lifting block 253, the scum cleaning component is lifted upward to discharge the cleaned scum;

[0049] A collecting component is installed on the side wall of the cleaning rack 3. The collecting component includes a fan blade 511 and a driving gear 521 connected by a synchronous belt 52, and a positioning rack 522 fixedly connected thereto. The teeth of the positioning rack 522 are located above the driving gear 521.

[0050] A positioning component is installed on the telescopic component. The positioning component positions the cleaning rack 3 after discharging, and pushes the driving gear 521 and the positioning rack 522 to engage during the reset process, completing the floating slag collection operation.

[0051] As Figures 1 to 12 shown, in the specific implementation, a base 11 is installed at the bottom of the air flotation machine body 1. A rib plate 111 is installed on the base 11. The other end of the rib plate 111 is installed and connected to the side wall of the air flotation machine body 1. Through the rib plate 111, the air flotation machine body 1 and the base 11 are connected more tightly. A water outlet pipe 12 is installed on the side wall of the air flotation machine body 1. An air inlet pipe 13 is installed on the other side wall of the air flotation machine body 1. A collection box 15 is installed on the back of the air flotation machine body 1. A fence 151 is installed on the collection box 15. A fixing rod 152 is installed on the fence 151. The collection box 15 is convenient for collecting the floating slag after discharging.

[0052] As Figures 1 to 12 shown, further, positioning frames 14 are installed on both side walls of the air flotation machine body 1. A reinforcing rib 141 is installed at the bent portion of the positioning frame 14. A positioning table 143 is installed on one side positioning frame 14. A driving motor 21 is installed on the positioning table 143. The output shaft of the driving motor 21 is connected to the rotation center of the adjusting roller 2. A positioning seat 142 is installed on the other side positioning frame 14. The positioning seat 142 is connected to the rotation center of the adjusting roller 2. The above structure positions the positions of the driving motor 21 and the adjusting roller 2.

[0053] Example 2:

[0054] Based on Example 1, the difference from this example is: As Figures 1 to 12As shown in the figure, a combined groove 22 is formed on the adjusting roller 2. The combined groove 22 is alternately composed of a pair of spiral grooves 221 and lifting grooves 222. The central angle corresponding to the lifting groove 222 corresponds to the central angle corresponding to the lifting block 253. A slider 23 is slidably installed at the bottom of the combined groove 22. A guide rod 231 is movably inserted through the slider 23. A fixed seat 232 is installed on the side wall of the guide rod 231. The fixed seat 232 is connected to the side wall of the air flotation machine body 1. The bottom of the slider 23 is connected to the output end of the telescopic assembly. By driving the driving motor 21 to drive the adjusting roller 2 to rotate at this time, the position of the combined groove 22 on the adjusting roller 2 can be changed. Through the guiding of the spiral groove 221 in the combined groove 22, the slider 23 sliding therein is driven to slide onto the central lifting groove 222. During this process, the slider 23 slides along the guide rod 231, mainly serving the purpose of guiding.

[0055] As Figures 1 to 12 shown, in the specific embodiment, the telescopic assembly includes a sleeve 24. A top rod 241 is movably inserted into the sleeve 24. The top of the top rod 241 is connected to the bottom of the slider 23. The above structure discloses the specific structure of the telescopic assembly. And a limiting rod 242 is movably inserted through the sleeve 24. Limiting seats 244 are installed at both ends of the limiting rod 242. The limiting seats 244 are installed on the cleaning frame 3. A limiting spring 243 is installed on the limiting rod 242. One end of the limiting spring 243 is clamped on the limiting seat 244, and the other end is clamped on the side wall of the sleeve 24. When the cleaning frame 3 slides, the limiting seat 244 on the cleaning frame 3 and the limiting rod 242 slide in the sleeve 24, and further squeeze the limiting spring 243 at this time, facilitating the later reset operation through the limiting spring 243. A synchronous bracket 25 is installed on the side wall of the sleeve 24. A synchronous plate 251 is installed on the top of the synchronous bracket 25. A protrusion 252 is installed on the bottom of the synchronous plate 251. The bottom of the protrusion 252 is smoothed. The protrusion 252 is slidably connected to the adjusting roller 2. Among them, the protrusion 252 can slide on the surface of the adjusting roller 2, reducing the friction force.

[0056] As Figures 1 to 12 shown, further, a plane 341 is installed on the guide seat 34. The end of the plane 341 is connected to the slope 342. And the side walls of the plane 341 and the slope 342 are smoothed. An extrusion rod 343 is installed on the side wall of the cleaning frame 3. A rolling ball 344 is installed at the end of the extrusion rod 343. The rolling ball 344 is slidably connected to the plane 341. The rolling ball 344 reduces the friction force generated by mutual sliding, making it better for sliding operation.

[0057] Embodiment 3:

[0058] Based on Embodiment 2, the difference from this embodiment is: As Figures 1 to 12As shown, one end of the cleaning rack 3 is provided with a side plate 32. A clamping shaft 332 is installed at the rotation center of the turning plate 33. A clamping seat 334 is installed on the clamping shaft 332. The clamping seat 334 is installed on the side wall of the cleaning rack 3. A clamping spring 333 is sleeved on the clamping shaft 332. One end of the clamping spring 333 is clamped on the clamping seat 334, and the other end of the clamping spring 333 is clamped on the turning plate 33. The clamping shaft 332 and the swing arm 331 are connected to each other. When the turning plate 33 of the cleaning rack 3 slides above the collection box 15, at this time, the swing arm 331 is in extrusion contact with the fixedly installed fixing rod 152. The swing arm 331 is rotated by extrusion, and the clamping shaft 332 on the swing arm 331 drives the turning plate 33 to rotate, thereby opening the chamber formed by a pair of cleaning racks 3, side plates 32 and turning plates 33. At this time, a part of the liquid and scum can slide down along the inclined surface of the scraping plate 31, achieving the purpose of automatic discharging.

[0059] As Figures 1 to 12As shown, in the specific implementation, the positioning component includes a fixing frame 4. A connecting plate 41 is installed at the center of the fixing frame 4. An installation plate 411 is welded on the connecting plate 41, and the installation plate 411 is installed on the guiding seat 34. A rectangular groove 42 is formed on the fixing frame 4. A vertical plate 421 is installed on the fixing frame 4 and penetrates through the rectangular groove 42. An installation groove 431 is formed on the rectangular groove 42 at the top corner near the center of the fixing frame 4. A baffle 43 is rotatably installed on the installation groove 431. A sliding rod 422 is slidably installed on the rectangular groove 42. The sliding rod 422 is connected to the synchronous bracket 25. An L-shaped frame 523 is installed on the fixing frame 4, and the L-shaped frame 523 is connected to the positioning rack 522. A rotating shaft 51 is installed on the fan blade 511, and the bottom position of the fan blade 511 is lower than the bottom position of the cleaning frame 3. The rotating shaft 51 is meshed with one end of the synchronous belt 52. A connecting frame 5 is installed on the rotation centers of the rotating shaft 51 and the driving gear 521. The connecting frame 5 is installed on the side wall of the synchronous bracket 25. The driving gear 521 is located below the positioning rack 522. During the process of the above-mentioned cleaning frame 3 sliding horizontally and then moving upward, the sliding rod 422 on the synchronous bracket 25 on the side wall of the sleeve 24 first slides horizontally along the rectangular groove 42, and then the sliding rod 422 vertically moves along the end of the rectangular groove 42. Finally, the sliding rod 422 presses the baffle 43, and at this time the baffle 43 flips. And when the sliding rod 422 is completely separated from the baffle 43, at this time the baffle 43 automatically resets by gravity and is clamped in the installation groove 431. So at this time the sliding rod 422 is lapped above the baffle 43 and slides on the rectangular groove 42 at this time, and then the cleaning frame 3 is driven to be positioned after discharging is completed. During the later reset process, at this time the cleaning frame 3 can only slide to both sides along the highest rectangular groove 42. During this process, the driving gear 521 that has moved upward will slide onto the positioning rack 522 at this time, and then the driving gear 521 rotates synchronously. The driving gear 521 drives the rotating shaft 51 to rotate in the same direction through the synchronous belt 52. Then the rotating shaft 51 can drive the fan blade 511 to rotate. During the rotation of the fan blade 511, the fan blade 511 slides the liquid towards the center, so that the newly generated scum in the liquid can gather towards the center, which is convenient for subsequent cleaning. When the driving gear 521 is separated from the positioning rack 522, at this time the cleaning frame 3 moves to the side of the rectangular groove 42 and resets along the vertical groove, and finally the purpose of restoring the initial state is achieved.

[0060] The implementation principle of an efficient shallow - layer air flotation machine of the present invention is as follows:

[0061] During the normal operation of the air flotation machine body 1, due to the buoyancy of the bubbles, the liquid impurities in the air flotation machine body 1 float to the water surface together with the bubbles, forming a scum layer floating on the top. Among them, the air flotation machine body 1 is a prior art, and its working principle will not be elaborated here.

[0062] When it is necessary to clean the scum layer, the operator can first start the drive motor 21. The drive motor 21 drives the adjusting roller 2 to rotate at this time. The position of the combined groove 22 on the adjusting roller 2 can change. Driven by the guide of the spiral groove 221 in the combined groove 22, the slider 23 sliding therein slides onto the central jacking groove 222. In this process, the slider 23 slides along the guide rod 231, mainly serving the purpose of guiding.

[0063] During the sliding process of the slider 23, the slider 23 can drive the entire cleaning frame 3 to slide towards the center through the telescopic assembly. The scraper 31 on the cleaning frame 3 can slide towards the center, and at this time, the scraper 31 slides along a height 1 cm below the liquid surface, thereby collecting the scum on the liquid surface layer. Finally, the two side scrapers 31 are inserted into each other, and the scraper 31 is inserted into the staggered gaps. At this time, a pair of cleaning frames 3, side plates 32, and turning plates 33 form a chamber, and at this time, the scum and a part of the liquid fall into the cavity. And in this process, the slider 23 just slides onto the spiral groove 221.

[0064] When the adjusting roller 2 continues to slide, the jacking block 253 of the adjusting roller 2 starts to rotate upward at this time. The jacking block 253 can jack up the protrusion 252, and the protrusion 252 drives the synchronous plate 251 and the synchronous bracket 25 to move upward. At this time, the synchronous bracket 25 drives the cleaning frame 3 to move upward through the sleeve 24. Finally, the collected scum moves upward and can be separated from the liquid surface.

[0065] And in this process, at this time, the cleaning frame 3 moves vertically upward. The extrusion rod 343 on the side wall of the cleaning frame 3 drives the rolling ball 344 to slide on the plane 341 of the guide seat 34. In this stage, finally, the bottom of the scraper 31 is separated from the liquid in the air flotation machine body 1, so that the scraper 31 moves above the air flotation machine body 1. At the same time, the extrusion rod 343 and the rolling ball 344 on the cleaning frame 3 slide on the plane 341 of the guide seat 34. When the scraper 31 is completely separated from the air flotation machine body 1, at this time, the rolling ball 344 will slide onto the slope 342, and then the entire cleaning frame 3 moves towards the collection box 15 side. When the turning plate 33 of the cleaning frame 3 slides above the collection box 15, at this time, the swing arm 331 makes extrusion contact with the fixedly installed fixed rod 152, the swing arm 331 is extruded and rotated, and the clamping shaft 332 on the swing arm 331 drives the turning plate 33 to rotate, thereby opening the chamber formed by a pair of cleaning frames 3, side plates 32, and turning plates 33. At this time, a part of the liquid and scum can slide downward along the inclined surface of the scraper 31, achieving the purpose of automatic unloading.

[0066] When moving to the discharging position on the cleaning rack 3, the connecting rack 5 moves upward synchronously at this time. The bottom fan blades 511 connected to the rotating shaft 51 on the connecting rack 5 will be lifted, and a part of the fan blades 511 will be inserted into the liquid. And at this time, the driving gear 521 on the connecting rack 5 moves upward synchronously, so that the driving gear 521 slides above the positioning rack 522.

[0067] When the cleaning rack 3 slides, the limit seat 244 and the limit rod 242 on the cleaning rack 3 slide in the sleeve 24, and further squeeze the limit spring 243 at this time, which facilitates the later reset operation through the limit spring 243.

[0068] During the process of the above-mentioned cleaning rack 3 sliding horizontally and then moving upward, the sliding rod 422 on the synchronous support 25 on the side wall of the sleeve 24 first slides horizontally along the loop groove 42, and then the sliding rod 422 moves vertically along the end of the loop groove 42. Finally, the sliding rod 422 squeezes the baffle 43. At this time, the baffle 43 flips, and when the sliding rod 422 is completely separated from the baffle 43, the baffle 43 automatically resets by gravity and is clamped in the installation groove 431. So at this time, the sliding rod 422 overlaps above the baffle 43 and slides on the loop groove 42 at this time, and then drives the cleaning rack 3 to be positioned after discharging is completed.

[0069] During the later reset, the cleaning rack 3 can only slide to both sides along the loop groove 42 at the highest position. During this process, the driving gear 521 that has moved upward will slide onto the positioning rack 522 at this time, and then the driving gear 521 rotates synchronously. The driving gear 521 drives the rotating shaft 51 to rotate in the same direction through the synchronous belt 52. Then the rotating shaft 51 can drive the fan blades 511 to rotate. During the rotation of the fan blades 511, the fan blades 511 slide the liquid towards the center, so that the newly generated scum in the liquid can gather towards the center, which is convenient for continued cleaning later. When the driving gear 521 is separated from the positioning rack 522, the cleaning rack 3 moves to the side of the loop groove 42 and resets along the vertical groove, and finally achieves the purpose of restoring the initial state.
