[0071] Embodiment 2

[0072] Reference Figure 7 - Fig.10 , which is the second embodiment of the present invention.

[0073] In this embodiment, preferably, a scraping member 300 for scraping oil from the inner wall of the oil-water separation box 100 is provided inside. The scraping member 300 can cooperate with the cooling and solidifying member 203. As the cooling and solidifying member 203 rotates, the scraping member 300 is driven to move upward, and moves downward under the action of gravity. The scraping member 300 moves up and down to scrape off the oil attached to the inner wall of the oil-water separation box 100 flush with the liquid surface and reposition it on the liquid surface, so as to facilitate the subsequent adsorption treatment of the cooled and solidified member 203. The scraping member 300 includes:

[0074] The oil scraping frame plate 301 is attached to the inner wall of the oil-water separation box 100. The plurality of oil scraping frame plates 301 are connected and fixed by connecting frames 302. The number of oil scraping frame plates 301 can be set as required, and the lowest oil scraping frame plate 301 will contact the bottom of the oil-water separation box 100 to limit the position of the oil scraping frame plate 301.

[0075] An extension plate 303 is installed on the right side of the upper end of the connecting frame 302, and an upper semicircular plate 304 is arranged on the lower surface of the right end of the extension plate 303. In order to cooperate with the rotation of the cooling and solidifying component 203, the upper semicircular plate 304 and the lower semicircular plate 305 can be designed as semispheres; the lower semicircular plate 305 is installed on the upper surface of the cooling and solidifying component 203 and can be fitted with the upper semicircular plate 304. The two semicircular plates cooperate with each other, which neither affects the rotation of the cooling and solidifying component 203 nor can it move upward against the upper semicircular plate 304.

[0076] In summary, when the cooling and solidifying component 203 moves toward the oil-water separation box 100, the lower semicircular plate 305 on the upper surface of the cooling and solidifying component 203 rotates to the upper semicircular plate 304, and the arc surfaces of the two are fitted together to drive the upper semicircular plate 304 to move upward, and drive the connecting frame 302 and the oil scraping frame plate 301 to move upward. The moving oil scraping frame plate 301 scrapes off the grease attached to the inner wall of the oil-water separation box 100 and floats on the water surface again, and the cooling and solidifying component 203 moves along with the electric telescopic rod 201. When the inner rod is retracted downward, the lower semicircular plate 305 is separated from the upper semicircular plate 304, and the upper semicircular plate 304 is not restricted. The oil scraper frame plate 301 will move downward to its original position under the action of gravity. When the cooled and solidified component 203 moves upward and rotates again, it will drive the oil scraper frame plate 301 to move upward again and return to its original position, so that the oil scraper frame plate 301 can continuously scrape off the grease attached to the inner wall of the oil-water separation box 100, making it convenient for the grease to float on the water surface and be adsorbed and collected again, thereby improving the cleanliness of the grease collection.

[0077] In this embodiment, preferably, an oil pipe cleaning structure 500 for cleaning the inner wall of the oil filling pipe is provided on the left side of the oil-water separation box 100. The oil pipe cleaning structure 500 does not affect the oil and water entering the oil-water separation box 100 through the oil inlet pipe 502, and can clean the inner wall of the oil inlet pipe 502 afterwards, so as to avoid the blockage caused by the long-term accumulation of grease inside the oil inlet pipe 502, and ensure the subsequent continuous separation and treatment of kitchen garbage oil and water. The oil pipe cleaning structure 500 includes:

[0078] A recoil water tank 501 is located on the left side of the oil-water separation tank 100, and an oil delivery pipe 503 is provided between the right side of the recoil water tank 501 and the left side of the oil-water separation tank 100;

[0079] The oil inlet pipe 502 is installed on the left side of the recoil water tank 501. The left end of the oil inlet pipe 502 can be connected to an external water pipe. A rotating oil scraping component 504 is arranged inside the oil inlet pipe 502 to clean the inner wall thereof.

[0080] In this embodiment, preferably, the rotating oil scraper component 504 includes a central twisted rod 5041 horizontally located at the center of the oil inlet pipe 502, both ends of the central twisted rod 5041 can be fixed to the inner wall of the oil inlet pipe 502 by a bracket, and the size of the bracket does not affect the inflow and outflow of oil and water, a sleeve 5042 is sleeved on the central twisted rod 5041, and the two are threadedly matched to facilitate the sleeve 5042 to rotate along the central twisted rod 5041, a fixing ring 5045 is sleeved on the outer side of the sleeve 5042, and a plurality of inclined blades 5044 are arranged circumferentially therebetween, and the inclination of the inclined blades 5044 is convenient for matching the inflow and outflow of liquid, an oil scraper ring 5043 is attached to the inner wall of the oil inlet pipe 502, an annular rail 5046 is arranged on the outer circumferential surface of the fixing ring 5045, and an annular groove 5047 that slides with the annular rail 5046 is arranged on the inner circumferential surface of the oil scraper ring 5043.

[0081] In summary, the oil and water treated by the previous extrusion enter the oil inlet pipe 502, and the oil and water impact on the inclined blade 5044 to rotate, and the rightward impact makes the inclined blade 5044 tend to move to the right. In conjunction with the twist pattern on the central twist rod 5041, the impact force makes the sleeve 5042 rotate and move along the central twist rod 5041, driving the oil scraper ring 5043 to move, and while moving, the grease impurities attached to the inner wall of the oil inlet pipe 502 are scraped off, and the oil and water enter the oil-water separation box 100. The oil scraper ring 5043 is located on the right side of the oil inlet pipe 502. When no oil and water enter, the inner wall of the oil inlet pipe 502 can be cleaned, and the recoil water tank 501 can be connected to the pump, and the pump removes the outside The water is sucked into the box and flushed to the left from the right side of the oil inlet pipe 502 to enter the interior. The water impacts the inclined blade 5044, driving the sleeve 5042 and the oil scraper ring 5043 to move to the left, scraping off the impurities and grease attached to the inner wall of the oil inlet pipe 502, and entering the oil storage tank on the left with the water. Then, high-pressure water is injected into the water pipe connected to the left side of the oil inlet pipe 502, and the oil scraper ring 5043 is moved to the right again, and the water and the carried grease are injected into the recoil water tank 501, and enter the oil-water separation box 100 through the oil delivery pipe 503. The whole process is repeated to achieve continuous cleaning of the inner wall of the oil inlet pipe 502, thereby maintaining the cleanliness of the inner wall of the oil inlet pipe 502 and the adequacy of grease collection.
