Description

[0019] Optionally, a process for a vortex flotation system for treating kitchen waste squeezed liquid, the specific steps are as follows:

[0020] S1: First, the overflow lifting plate is extended out of the support base by supporting the rotating control rod through the second support plate, and the lifting height of the overflow lifting plate is controlled according to the use needs, so as to prevent the sewage from overflowing into the garbage collection tank, and then the first solenoid valve is opened to discharge the kitchen waste squeezed liquid from the input water pipe into the aeration tank, and the vortex aerator supported by the first support plate is started to inject microbubbles into the sewage in the aeration tank through the air diffusion impeller, and the solid suspended matter in the squeezed liquid is brought to the water surface by the rise of the microbubbles;

[0021] S2: Then, the solid garbage suspended on the water surface is started by the third motor to drive the transmission gear to rotate, which is then driven by the connecting rod to drive the transmission gear to rotate together, and then the meshing transmission chain is driven to rotate and move, and the transmission chain is driven to drive the supporting scraper plate to rotate back and forth to push the solid garbage suspended on the water surface onto the inclined mud plate and into the garbage collection tank. At the same time, the reaction force of the first spring causes the telescopic scraper plate to extend from the inside of the first telescopic slide slot, so that the telescopic scraper plate fits tightly with the inclined mud plate, thereby driving the telescopic scraper plate to move and fully push the garbage into the garbage collection tank by pushing the garbage through the supporting scraper plate, thereby preventing the garbage from remaining attached to the inclined mud plate;

[0022] S3: At the same time, the garbage pushed into the garbage collection tank is driven to rotate by the second motor, and the rotation of the shaft drives the cutting blade thereon to rotate to cut and crush the larger garbage, thereby effectively preventing the garbage from being blocked due to excessive volume and inconvenient to discharge and clean. After crushing, the first motor is started to drive the conveying roller to rotate in the garbage collection tank, and the crushed garbage rolls are sent to the garbage discharge tank for centralized discharge and cleaning;

[0023] S4: Secondly, while some of the unsuspended garbage moves with the water flow, the garbage is filtered, separated and blocked by the filter screen. After the filter screen is hit by the garbage, it slides on the buffer slide rod, and the reaction force of the second spring is used to buffer and reduce the shock of the collision force, thereby protecting the filter screen from damage. After long-term use, the electric push rod protected by the waterproof box is activated to telescope and drive the moving block to move back and forth on the side wall of the supporting slide rail, and the reaction force of the third spring causes the anti-blocking scraper to be forced to extend from the second telescopic slide groove and fit closely to the surface of the filter screen, and then the moving block moves to drive the fixed plate to move, and the fixed plate moves back and forth to drive the anti-blocking scraper to scrape and clean the garbage blocked on the surface of the filter screen during the back and forth movement, thereby avoiding garbage accumulation and blockage that affects normal filtration;

[0024] S5: Finally, the fixed plate moves back and forth, thereby driving the rotating roller supported by the fixed rod to move. The rotating roller moves and is affected by the resistance of the water to rotate on the fixed rod, so that the rotating roller drives the stirring blade to rotate to stir the sewage, so that the garbage is active in the sewage and prevents it from settling at the bottom of the flotation tank. Then, the air diffuser impeller generates microbubbles at the bottom of the aeration tank and forms a negative pressure zone at the bottom of the aeration tank. The pressure in the negative pressure zone causes the sewage with garbage at the bottom of the flotation tank to be sucked back into the aeration tank through the reflux tank and re-aerated to be suspended on the water surface. Finally, the sewage after the garbage separation treatment is discharged through the output water pipe by opening the second solenoid valve, thereby completing the treatment of the kitchen waste squeezed liquid.

[0025] The present invention has at least the following beneficial effects:

[0026] (1) This scheme sets up a filtering and anti-blocking mechanism, specifically, through the filter screen plate to filter, separate and block the garbage, and the filter screen plate slides on the buffer slide rod after being hit by the garbage, and the reaction force of the second spring is used to buffer and reduce the shock of the impact force, thereby protecting the filter screen from damage. After long-term use, the electric push rod protected by the waterproof box starts to telescope and drives the moving block to move back and forth on the side wall of the supporting slide rail, and the reaction force of the third spring causes the anti-blocking scraper to be forced to extend from the second telescopic slide groove and fit closely to the surface of the filter screen plate, and then the moving block drives the fixed plate to move, and the fixed plate moves back and forth to drive the anti-blocking scraper to scrape and clean the garbage blocked on the surface of the filter screen plate during the back and forth movement, so as to avoid garbage accumulation and blockage that affects normal filtration, thereby achieving the purpose of effectively facilitating the filtering, separation and blocking of non-suspended solid garbage, avoiding garbage from being directly discharged with the water flow, effectively improving the separation and treatment effect of garbage, and making the garbage separation fully and thoroughly;

[0027] (2) This scheme sets up a sufficient scraping mechanism, specifically, the third motor is started to drive the transmission gear to rotate, which is driven by the connecting rod transmission to drive the transmission gear to rotate together, and then drives the meshing transmission chain to rotate and move, and the transmission chain moves to drive the supporting scraper plate to rotate back and forth to push the solid garbage suspended on the water surface onto the inclined mud plate and into the garbage collection tank. At the same time, the reaction force of the first spring causes the telescopic scraper plate to extend from the inside of the first telescopic slide groove, so that the telescopic scraper plate and the inclined mud plate fit closely, so that the supporting scraper plate pushes the garbage while driving the telescopic scraper plate to move and fully push the garbage into the garbage collection tank, preventing the garbage residue from sticking to the inclined mud plate, thereby achieving the purpose of effectively and conveniently pushing and cleaning the garbage and preventing the garbage residue from affecting the subsequent cleaning and discharge;

[0028] (3) This solution sets up a crushing mechanism, specifically, the second motor is started to drive the rotating shaft to rotate, and the rotating shaft rotates to drive the cutting blades thereon to rotate to cut and crush the large volume of garbage, thereby achieving the purpose of effectively facilitating the crushing of large volume of garbage and preventing the situation where the garbage is too large to cause blockage and inconvenience in discharge and cleaning;

[0029] (4) This scheme sets up an anti-sedimentation mechanism. Specifically, the fixed plate moves back and forth, thereby driving the rotating roller supported by the fixed rod to move. The rotating roller is affected by the resistance of the water and rotates on the fixed rod. The rotating roller drives the stirring blade to rotate to stir the sewage and make the garbage active in the sewage, thereby effectively preventing the garbage from settling at the bottom of the flotation tank and allowing the garbage to fully flow back and circulate for separation and treatment.

[0054] In actual application, the conveying mechanism 2 includes an input water pipe 201, a first solenoid valve 202, an output water pipe 203 and a second solenoid valve 204. One end of the input water pipe 201 is fixedly connected to one end of the flotation tank 1, and the kitchen waste squeezed liquid is conveniently conveyed to the flotation tank 1 through the input water pipe 201. The first solenoid valve 202 is fixedly installed on the side wall of the input water pipe 201, and the opening and closing of the input water pipe 201 are controlled by the first solenoid valve 202. One end of the output water pipe 203 is fixedly connected to the other end of the flotation tank 1, and the treated sewage is conveniently discharged through the output water pipe 203. The second solenoid valve 204 is fixedly installed on the side wall of the output water pipe 203, and the opening and closing of the output water pipe 203 are controlled by the second solenoid valve 204.

[0055] The working process and principle of the present invention are as follows: first, the second support plate 601 supports the rotating control rod 602 to drive the overflow lifting plate 603 to extend out from the support base 604, and the lifting height of the overflow lifting plate 603 is controlled according to the use needs, so as to prevent the sewage from overflowing into the garbage collection tank 402, and then the first solenoid valve 202 is opened to discharge the kitchen waste squeezed liquid from the input water pipe 201 into the aeration tank 304, and the vortex aerator 302 supported by the first support plate 301 is started to inject microbubbles into the sewage in the aeration tank 304 through the air diffusion impeller 303, and the solid suspended matter in the squeezed liquid is brought to the water surface by the rise of the microbubbles, and then the solid garbage suspended on the water surface is started by the third motor 702 to drive the transmission gear The wheel 703 rotates, and the transmission is transmitted through the connecting rod 704, thereby driving the transmission gear 703 to rotate together, and then driving the meshing transmission chain 705 to rotate and move. The movement of the transmission chain 705 drives the supporting scraper plate 706 to rotate back and forth to push the solid garbage suspended on the water surface onto the inclined mud plate 401 and into the garbage collection tank 402. At the same time, the reaction force of the first spring 708 causes the telescopic scraper plate 709 to extend from the inside of the first telescopic slide groove 707, so that the telescopic scraper plate 709 is closely fitted with the inclined mud plate 401, so that the supporting scraper plate 706 moves to push the garbage while driving the telescopic scraper plate 709 to move and fully push the garbage into the garbage collection tank 402, preventing the garbage from remaining attached to the inclined mud plate 401, thereby achieving the purpose of effectively and conveniently pushing and cleaning the garbage and avoiding the influence of garbage residue on subsequent cleaning and discharge. At the same time, the garbage pushed into the garbage collection tank 402 is driven by the second motor 501 to rotate the rotating shaft 502, and the rotation of the rotating shaft 502 drives the cutting blade 503 thereon to rotate to cut and crush the larger garbage, thereby achieving the purpose of effectively and conveniently crushing the large-volume garbage and preventing the garbage from being blocked due to excessive volume and inconvenient to discharge and clean. After crushing, the first motor 403 is started to drive the conveying roller 404 to rotate in the garbage collection tank 402, and the crushed garbage rolls are sent to the garbage discharge tank 405 for centralized discharge and cleaning. Secondly, while some of the unsuspended garbage moves with the water flow, the garbage is filtered, separated and blocked by the filter screen plate 803. After the filter screen plate 803 is hit by the garbage, it slides on the buffer slide bar 802, and the reaction force of the second spring 804 is used to buffer and reduce the shock, thereby protecting the filter screen plate 803 from damage. After long-term use, the electric push rod 807 protected by the waterproof box 806 is activated to telescope and drive the moving block 808 to move back and forth on the side wall of the supporting slide rail 805, and the reaction force of the third spring 811 makes the anti-blocking scraper 812 stretched out from the second telescopic slide groove 810 and fit closely with the surface of the filter screen plate 803, and then the moving block 808 moves to drive the fixed plate 809 to move.The fixed plate 809 moves back and forth, thereby driving the anti-blocking scraper 812 to scrape and clean the garbage blocked on the surface of the filter screen plate 803 during the back and forth movement, so as to avoid garbage accumulation and blockage that affects normal filtration, thereby effectively facilitating the filtration and separation of non-suspended solid garbage, avoiding the garbage from being directly discharged with the water flow, effectively improving the separation and treatment effect of the garbage, and achieving the purpose of sufficient and thorough garbage separation. Finally, the fixed plate 809 moves back and forth, thereby driving the rotating roller 902 supported by the fixed rod 901 to move, and the rotating roller 902 moves and rotates on the fixed rod 901 due to the resistance of the water, so that the rotating roller 902 rotates. The stirring blade 903 is driven to rotate to stir the sewage so that the garbage is active in the sewage, so as to effectively prevent the garbage from settling at the bottom of the flotation tank 1 and make the garbage fully reflux and circulate for separation and treatment. Then, the air diffuser 303 generates microbubbles at the bottom of the aeration tank 304, and at the same time forms a negative pressure zone at the bottom of the aeration tank 304. The pressure of the negative pressure zone causes the sewage with garbage at the bottom of the flotation tank 1 to be sucked back into the aeration tank 304 through the reflux tank 305 and re-aerated so as to be suspended on the water surface. Finally, the sewage after the garbage separation treatment is discharged through the output water pipe 203 by opening the second solenoid valve 204, completing the treatment of the kitchen garbage squeezed liquid.

At the same time, the reaction force of the first spring (708) causes the telescopic scraper plate (709) to extend from the inside of the first telescopic sliding groove (707), so that the telescopic scraper plate (709) and the inclined mud plate (401) are closely attached, so that the support scraper plate (706) moves to push the garbage and drives the telescopic scraper plate (709) to move and fully push the garbage into the garbage collection tank (402), preventing the garbage from being attached to the inclined mud plate (401); S3: The garbage pushed into the garbage collection tank (402) is driven to rotate by the second motor (501), and the rotation of the rotating shaft (502) drives the cutting blade (503) thereon to rotate to cut and crush the garbage with a large volume, thereby effectively preventing the garbage from being blocked due to its large volume and being inconvenient to discharge and clean.

After the filter screen (803) is hit by the garbage, it slides on the buffer slide bar (802), and the impact force is buffered and damped by the reaction force of the second spring (804), thereby protecting the filter screen (803) from damage. After long-term use, the electric push rod (807) protected by the waterproof box (806) starts to extend and retract to drive the moving block (808) on the supporting slide rail (805).

The rotating roller (902) rotates on the fixed rod (901) due to the resistance of the water. The rotating roller (902) rotates and drives the stirring blade (903) to rotate to stir the sewage, so that the garbage is active in the sewage and prevents it from settling at the bottom of the flotation tank (1). Then, the air diffuser (303) generates microbubbles at the bottom of the aeration tank (304) and forms a negative pressure zone at the bottom of the aeration tank (304). The pressure of the negative pressure zone causes the sewage with garbage at the bottom of the flotation tank (1) to be sucked back into the aeration tank (304) through the reflux tank (305) and re-aerated so as to be suspended on the water surface. Finally, the sewage after the garbage separation treatment is discharged through the output water pipe (203) by opening the second electromagnetic valve (204), thereby completing the treatment of the kitchen garbage squeezed liquid.
