Optionally, a process of using a vortex air flotation system for food waste squeeze liquid treatment, the specific steps are as follows:

S1: First, support the second support plate and rotate the control rod to drive the overflow lifting plate to extend from the support base. Control the lifting height of the overflow lifting plate according to the needs of use, thereby preventing sewage from overflowing into the garbage concentration tank, and then through The first solenoid valve is opened to discharge the food waste pressed liquid from the input water pipe into the aeration tank, and the vortex aerator supported by the first support plate is started to drive microbubbles into the aeration tank through the diffusion impeller. In the sewage, the suspended solids in the squeezed liquid are brought to the water surface by the rise of microbubbles;

S2: Then, the solid garbage suspended on the water surface is started by the third motor to drive the transmission gear to rotate, and is driven by the connecting rod to drive the transmission gear to rotate together, and then drives the meshed transmission chain to rotate and move, and the transmission chain moves to drive the supporting mud scraper. The plate rotates back and forth to push the solid garbage suspended on the water surface onto the inclined mud plate and into the garbage concentration chute. At the same time, the reaction force of the first spring causes the telescopic scraper to extend from the inside of the first telescopic chute. Make the telescopic scraper and the inclined mud plate closely fit, thereby pushing the garbage by supporting the movement of the scraper and driving the telescopic scraper to move and fully push the garbage into the garbage concentration tank to prevent the garbage residue from adhering to the inclined mud plate. on board;

S3: At the same time, the garbage pushed into the garbage concentration tank is started by the second motor to drive the rotation of the rotating shaft. The rotation of the rotating shaft drives the cutting blade on it to rotate to cut and crush the larger garbage, thereby effectively preventing the garbage from being oversized. It is easy to cause blockage and is inconvenient for discharge and cleaning. After crushing, the first motor is started to drive the conveyor roller to rotate in the garbage concentration trough, and the crushed garbage rolls are sent to the garbage discharge trough for centralized discharge and cleaning;

S4: Secondly, while part of the unsuspended garbage moves with the water flow, the garbage is filtered, separated and blocked by the filter screen plate. After being impacted by the garbage, the filter screen plate slides and moves on the buffer slider, and passes through the reaction force of the second spring. The impact force is cushioned and shock-absorbed to protect the filter plate from damage. After long-term use, the electric push rod protected by the waterproof box is used to telescopically drive the moving block to move back and forth on the side wall of the supporting slide rail, and through The reaction force of the third spring causes the anti-blocking scraper to stretch out from the second telescopic chute and fit closely with the surface of the filter plate. The moving block moves the fixed plate to move, and the fixed plate moves back and forth to drive the anti-blocking scraper. During the process of moving back and forth, the blocking scraper scrapes and cleans the garbage blocked on the surface of the filter plate to avoid accumulation and blockage of garbage and affecting normal filtration;

S5: Finally, the fixed plate moves back and forth to drive 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 mixing blade to rotate to stir the sewage. Garbage is active in the sewage to avoid settling at the bottom of the flotation tank. The diffuser impeller generates microbubbles at the bottom of the aeration tank and at the same time forms a negative pressure zone at the bottom of the aeration tank. The pressure in the negative pressure zone makes the air float. The sewage with garbage at the bottom of the tank is sucked back into the aeration tank through the return tank and re-aerated to be suspended on the water surface. Finally, the sewage after garbage separation is opened by the second solenoid valve to discharge the sewage through the output water pipe. , complete the processing of kitchen waste squeezed liquid.

The present invention at least has the following beneficial effects:

(1) This solution sets up a filtering and anti-clogging mechanism, specifically filtering, separating and blocking the garbage through the filter plate. After the filter plate is impacted by the garbage, it slides and moves on the buffer slider, and the impact is prevented by the reaction force of the second spring. The force is used for buffering and shock absorption, thereby protecting the filter plate from damage. After long-term use, the telescopic push rod is started by the electric push rod protected by the waterproof box to drive the moving block to move back and forth on the side wall of the supporting slide rail, and through the third The reaction force of the spring causes the anti-blocking scraper to stretch out from the second telescopic chute and fit closely with the surface of the filter plate. The moving block then moves the fixed plate, and the fixed plate moves back and forth to drive the anti-blocking scraper. When the plate moves back and forth, it scrapes and cleans the garbage blocked on the surface of the filter plate to avoid accumulation and blockage of garbage, which will affect normal filtration, thereby effectively filtering, separating and blocking unsuspended solid garbage, and preventing garbage from being randomly distributed. Discharge directly with the water flow, effectively improving the separation and processing effect of garbage, and achieving the purpose of fully and thoroughly separating garbage;

(2) This plan sets up a sufficient mud scraping mechanism, specifically starts the third motor to drive the transmission gear to rotate, drives the transmission gear to rotate together through connecting rod transmission, and then drives the meshed transmission chain to rotate and move, and the transmission chain moves to thereby The support scraper is driven to rotate back and forth to push the solid garbage suspended on the water surface to the inclined mud plate and into the garbage concentration chute. At the same time, the reaction force of the first spring causes the telescopic scraper to move from the first telescopic chute. The inside extends to make the telescopic scraper and the inclined mud plate fit closely, thereby pushing the garbage by supporting the movement of the scraper and driving the telescopic scraper to move and fully push the garbage into the garbage concentration tank to prevent garbage residue from sticking. Attached to the inclined mud plate, it can effectively and conveniently push and clean the garbage, and avoid the impact of garbage residue on subsequent cleaning and discharge;

(3) This solution sets up a crushing mechanism, and specifically starts the second motor to drive the rotating shaft to rotate. The rotating shaft rotates to drive the cutting blade on it to rotate to cut and crush larger-volume garbage, so as to effectively facilitate the processing of large-volume garbage. The garbage is crushed to prevent the garbage from being too large and causing blockage, which is inconvenient for discharge and cleaning;

(4) This solution sets up an anti-sedimentation mechanism, specifically moves back and forth through the fixed plate, thereby driving the rotating roller supported by the fixed rod to move. The rotating roller is affected by the resistance of water and rotates on the fixed rod, thereby rotating through the rotating roller. The stirring blade is driven to rotate to stir the sewage so that the garbage is active in the sewage, effectively preventing the garbage from settling at the bottom of the flotation tank, and allowing the garbage to fully flow back, circulate, and be separated for treatment.

The working flow and principle of the present invention: First, the second support plate 601 supports the rotating control rod 602 to drive the overflow lifting plate 603 to extend from the support base 604, and controls the lifting height of the overflow lifting plate 603 according to the needs of use, thereby preventing The sewage overflows into the garbage concentration tank 402, and then the first solenoid valve 202 is opened so that the food waste pressed liquid is discharged from the input water pipe 201 into the aeration tank 304, and is aerated through the vortex supported by the first support plate 301 The machine 302 is started to drive micro bubbles into the sewage in the aeration tank 304 through the diffuser impeller 303. The micro bubbles rise to bring the solid suspended matter in the squeezed liquid to the water surface. Then, the solid garbage suspended on the water surface passes through the third The three motors 702 are started to drive the transmission gear 703 to rotate, and are driven by the connecting rod 704 to drive the transmission gear 703 to rotate together, and then drive the meshed transmission chain 705 to rotate and move. The movement of the transmission chain 705 drives the support scraper 706 to rotate and move back and forth. The solid garbage suspended on the water surface is pushed onto the inclined mud plate 401 and pushed into the garbage concentration chute 402. At the same time, the reactive force of the first spring 708 causes the telescopic scraper 709 to extend from the inside of the first telescopic chute 707. The telescopic scraper 709 is closely attached to the inclined mud plate 401, thereby pushing the garbage by supporting the movement of the scraper 706 and driving the telescopic scraper 709 to move and fully push the garbage into the garbage concentration tank 402 to prevent garbage residue. It is attached to the inclined mud plate 401, so as to effectively facilitate and fully push and clean the garbage, and avoid the garbage residue from affecting the subsequent cleaning and discharge. At the same time, the garbage pushed into the garbage concentration tank 402 is started by the second motor 501. The rotating shaft 502 is driven to rotate, and the cutting blade 503 on the rotating shaft 502 is rotated to rotate to cut and crush larger-volume garbage, thereby effectively and conveniently crushing large-volume garbage and preventing the garbage from being easily blocked due to excessive volume. The situation is inconvenient for the purpose of discharge and cleaning. After crushing, the first motor 403 is started to drive the conveyor roller 404 to rotate in the garbage concentration chute 402, and the crushed garbage rolls are sent to the garbage discharge chute 405 for centralized discharge for cleaning. Secondly, while part of the unsuspended garbage moves with the water flow, the garbage is filtered, separated and blocked by the filter plate 803. After being impacted by the garbage, the filter plate 803 slides and moves on the buffer slider 802, and is passed by the second spring 804. The reaction force cushions the impact force, thereby protecting the filter plate 803 from damage. After long-term use, the electric push rod 807 protected by the waterproof box 806 starts to telescope and drives the moving block 808 on the side of the support slide rail 805. The wall moves back and forth, and the reaction force of the third spring 811 causes the anti-blocking scraper 812 to stretch out from the second telescopic chute 810 and closely fit the surface of the filter plate 803, and is driven by the movement of the moving block 808. The fixed plate 809 moves, and the fixed plate 809 moves back and forth, thereby driving the anti-clogging scraper 812 to scrape and prevent clogging of the garbage blocked on the surface of the filter plate 803 during the back and forth movement, so as to avoid garbage accumulation and blockage, thereby affecting normal filtration. In order to achieve the purpose of effectively filtering, separating and blocking unsuspended solid waste, preventing the garbage from being discharged directly with the water flow, effectively improving the separation treatment effect of the garbage, and making the garbage separation fully and thoroughly, finally, the fixed plate 809 is moved back and forth, thereby The rotating roller 902 supported by the fixed rod 901 is driven to move. The rotating roller 902 is affected by the resistance of the water and rotates on the fixed rod 901. Thus, the rotating roller 902 drives the stirring blade 903 to rotate to stir the sewage and make the garbage active in the sewage. , to effectively prevent the garbage from settling at the bottom of the air flotation tank 1, so that the garbage can fully recirculate and separate for treatment, and then use the diffuser impeller 303 to generate micro bubbles at the bottom of the aeration tank 304, and at the same time form a negative pressure at the bottom of the aeration tank 304. Pressure zone, through the pressure of the negative pressure zone, the sewage with garbage at the bottom of the air flotation tank 1 is sucked back into the aeration tank 304 through the return tank 305 and re-aerated to be suspended on the water surface. Finally, the sewage after garbage separation is , and then the second solenoid valve 204 is opened so that the sewage is discharged through the output water pipe 203 to complete the processing of the food waste squeezed liquid.
