[0021] Reference Figures 4 to 8An adaptive medicine adding component is rotatably connected to the linear slider 13, and the adaptive medicine adding component includes a transfer rod 24 that is rotatably connected to the linear slider 13. Both ends of the transfer rod 24 are fixedly connected to gears 25. Two tooth plates 26 are fixedly connected to the outer wall of the linear guide rail 12.

It should be noted that the two ends of the fan-shaped scraper 43 are in sliding cooperation with the side walls of the linear guide 12, that is, the linear guide 12 will limit the fan-shaped scraper 43. When the No. 2 lifting block 16 rotates, the lubricated bearing can prevent the fan-shaped scraper 43 from having a rotation tendency. At the same time, the fan-shaped scraper 43 can move up and down smoothly through the limiting cooperation of the linear guide 12 on the fan-shaped scraper 43.

When the main stirring rod 38 and the auxiliary stirring rods 41 are used to stir the wastewater, the ups and downs generated by the upper wastewater will also push the baffle 46, so that the straight rod 44 can rotate relative to the fan-shaped scraper 43, and the arc pressure spring 48 can be used to The elastic force pushes the elastic slider 54, which can increase the frequency and speed of the straight rod 44 rotating relative to the fan-shaped scraper 43, so that the concave cleaning block 47 can move relative to the fan-shaped scraper 43 and self-clean the cleaning objects on the fan-shaped scraper 43, so as to realize the synchronous self-cleaning of the inner wall of the treatment tube 4 and the fan-shaped scraper 43, effectively reducing the subsequent cleaning work cost, and after the treatment is completed, the wastewater can be discharged through the water collection port 55 opened at the bottom. At this time, the reduction in the wastewater water level will drive the fan-shaped scraper 43 to move downward, and the dirt on the inner wall of the treatment tube 4 will be scraped off again.

[0024] The working principle of the present invention is as follows: When the device is in use, after the kitchen waste enters the feed hopper 2, part of the waste water enters the treatment barrel 4 through the drain pipe 5, and the stepper motor 19 is controlled to start, and the stepper motor 19 drives the rotating shaft 17 and the push plate 20 to rotate 180 degrees, so as to flip the kitchen waste into the pressing frame 3, and then the electric push rod 22 is controlled to drive the pressing plate 23 to move upward, so that the pressing plate can squeeze the kitchen waste, and squeeze the waste water in the kitchen waste into the feed hopper 2 through the push plate 20, so that the waste water can enter the treatment barrel 4 through the drain pipe 5, so as to quickly complete the dry and wet separation operation of the kitchen waste in the feed hopper 2; During the process of wastewater passing through the drain pipe 5 into the treatment barrel 4, the servo motor 15 is controlled to drive the spline shaft 6 to rotate, so that the second lifting block 16, the main stirring rod 38 and the plurality of auxiliary stirring rods 41 rotate synchronously and stir the wastewater in the treatment barrel 4, so that the wastewater begins to circulate in the treatment barrel 4 and the wastewater in the upper layer fluctuates. Since the floating airbag 11 floats on the upper layer of the wastewater, the floating airbag 11 can swing, and the liquid storage tank 10 is driven to swing synchronously through the connection and cooperation of the double-section universal coupling 9 and the single-section universal coupling 14, so that the composite water pollution control agent in the liquid storage tank 10 can continue to shake during the process of adding it into the wastewater; As the wastewater enters the treatment barrel 4, the water level of the wastewater in the treatment barrel 4 gradually rises, and the floating airbag 11 and the liquid storage tank 10 can gradually rise and move as the wastewater level rises. When the liquid storage tank 10 rises and moves, it will synchronously drive the linear slider 13 to move upward. At this time, the meshing transmission of the gear 25 and the toothed plate 26 can drive the transfer rod 24 to rotate, so that the circumferential guide rod 27 rotates synchronously and periodically pulls and pushes the T-shaped limit block 30 through the transmission action of the transmission rod 31, so that the T-shaped limit block 30 is The block 30 can slide back and forth at the limit sliding hole 29, so that the connecting rod 36 can drive the sealing plate 35 to slide back and forth in the suction cylinder 32 to periodically change the pressure of the sealed space formed by the suction cylinder 32 and the sealing plate 35, so that the suction cylinder 32 can reciprocally suck the composite water pollution control agent from the liquid storage tank 10, and add the composite water pollution control agent into the wastewater through the discharge nozzle 34. When the wastewater level in the treatment cylinder 4 stops rising, the suction cylinder 32 immediately stops the suction action; During the process of the wastewater level rising in the treatment barrel 4, since the arc-shaped floating plates 39 also float on the upper layer of the wastewater, the main stirring rod 38 can be driven to move upward when the wastewater level rises, and then the transmission effect of the scissor-type connecting rod groups 40 and the gravity effect of the several auxiliary stirring rods 41 below are used to make the several auxiliary stirring rods 41 gradually extend, so that the main stirring rod 38 and the several auxiliary stirring rods 41 can fully and evenly stir and mix the wastewater; As the arc-shaped floating plates 39 rise and fall with the increase or decrease of the wastewater level, the No. 2 lifting block 16 can be lifted and lowered synchronously and drive the fan-shaped scraper 43 to move up and down, so that the fan-shaped scraper 43 can move relative to the inner wall of the treatment tube 4 and scrape and clean the solids adhering to the inner wall of the treatment tube 4. When the main stirring rod 38 and the auxiliary stirring rods 41 are used to stir the wastewater, the ups and downs generated by the upper wastewater will also push the baffle 46, so that the straight rod 44 can rotate relative to the fan-shaped scraper 43. At the same time, the elastic force of the arc-shaped pressure spring 48 can be used to push the elastic slider 54, which can increase the frequency and speed of the rotation of the straight rod 44 relative to the fan-shaped scraper 43, thereby enabling the concave cleaning block 47 to move relative to the fan-shaped scraper 43 and self-clean the cleaning objects on the fan-shaped scraper 43, so as to realize the synchronous self-cleaning of the inner wall of the treatment tube 4 and the fan-shaped scraper 43.
