[0002] In the production and processing of edible oil, the storage of semi-finished oil is a crucial step. As the core storage equipment, the ease of use and cleanliness of oil storage tanks directly affect production efficiency and the quality of semi-finished oil. Currently, most oil storage tanks for semi-finished edible oil on the market are traditional sealed tanks with simple structures, which can only achieve the basic storage function of semi-finished oil and cannot solve the problem of cleaning after use.

[0003] Because semi-finished oil may contain small amounts of grease residue and impurities, these can adhere to the inner wall of the tank after long-term storage. Therefore, the tank must be thoroughly cleaned after use to prevent residual impurities from contaminating subsequently stored semi-finished oil. Current cleaning methods mainly rely on manual labor. Before cleaning, the remaining grease in the tank must be drained and the tank ventilated. Then, workers enter the tank to clean the inner wall residue by wiping and rinsing. This process is cumbersome, time-consuming, and labor-intensive, not only consuming significant manpower but also resulting in low cleaning efficiency.

[0004] Therefore, the development of a storage tank for semi-finished edible oil that simplifies the cleaning process and eliminates the need for cumbersome manual operations has become an urgent need in the industry. Utility Model Content

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] Please see Figure 1-5 A semi-finished edible oil storage tank includes a tank body 1, wherein the tank body 1 is made of food-grade stainless steel, the top surface of the tank body 1 is provided with a filling port, a sealing cap is installed on the filling port, the bottom side of the tank body 1 is provided with an oil outlet, and a hollow tube 2 is movably inserted into the top surface of the tank body 1. The hollow tube 2 is a hollow cylindrical structure that can slide flexibly up and down along the top surface of the tank body 1.

[0024] The tank body 1 is also equipped with a drive assembly that drives the hollow tube 2 to move up and down. The end of the hollow tube 2 located inside the tank body 1 is fixedly equipped with a lifting seat 3. The lifting seat 3 is equipped with a cleaning assembly, which is used to automatically clean the grease residue and impurities on the inner wall and bottom of the tank, thereby realizing automatic cleaning of the tank. The cleaning assembly includes a scraper 4 fixedly installed on the lifting seat 3 and a rotating part 5 rotatably installed on the bottom surface of the lifting seat 3. Both the scraper 4 and the rotating part 5 are provided with weight reduction holes. The scraper 4 is a circular ring structure, and the rotating part 5 is a circular disc that can rotate flexibly around the bottom surface of the lifting seat 3. A silicone scraper ring 6 is installed on the outer ring side wall of the scraper 4. The silicone scraper ring 6 is a ring elastic structure that fits tightly against the inner wall of the tank, which can thoroughly scrape off the residue on the inner wall while avoiding damage to the inner wall of the tank. The rotating part 5 is driven by a first motor 7 installed inside the lifting seat 3, and multiple silicone scraper strips 8 are fixedly installed on the bottom surface of the rotating part 5. The silicone scraper strips 8 are arranged in a uniform array, are soft and fit the bottom surface of the tank, and are used to scrape off residual impurities on the bottom surface of the tank.

[0025] The lifting seat 3 is equipped with multiple nozzles 9 arranged in an array on the side wall between the scraper 4 and the rotating component 5. These nozzles 9 are connected to an annular pipe 10 inside the lifting seat 3. The nozzles 9 are atomizing nozzles used to spray cleaning fluid, working in conjunction with the cleaning components to improve the cleaning effect. The annular pipe 10 is a hollow annular pipe used to evenly distribute the cleaning fluid to each nozzle 9, ensuring uniform spraying. The annular pipe 10 is connected to a conveying pipe 11 inside the hollow pipe 2. The conveying pipe 11 is used to transport the cleaning fluid, introducing external cleaning fluid into the annular pipe 10. A pump body is connected to the external conveying pipe 11 to provide power for the delivery of the cleaning fluid, ensuring stable spraying. The cleaning fluid and the cleaning components work together to thoroughly remove stubborn residue from the inner wall and bottom of the tank, solving the problems of blind spots and incomplete cleaning that are common with manual cleaning, further improving the cleaning effect, ensuring tank cleanliness, and preventing residual impurities from contaminating subsequent semi-finished products.

[0026] Preferably, the nozzle 9 is tilted towards the silicone scraper ring 6. This tilt allows some of the cleaning fluid to be sprayed directly onto the silicone scraper ring 6. While the cleaning component is working, the silicone scraper ring 6 is cleaned simultaneously to remove residues adhering to the scraper ring, achieving synchronous self-cleaning of the silicone scraper ring. This prevents residues from adhering to the scraper ring and affecting the subsequent cleaning effect. The silicone scraper strip 8 at the bottom of the rotating component 5 is immersed in the cleaning fluid and can self-clean during rotation, eliminating the need for separate cleaning of the silicone scraper strip 8.

[0027] In addition, multiple reinforcing ribs 13 are arrayed between the side wall of the hollow tube 2 and the lifting seat 3. The reinforcing ribs 13 are rigid strip structures used to enhance the connection strength between the hollow tube 2 and the lifting seat 3 and prevent the lifting seat 3 from shaking or shifting during lifting and cleaning. The top surface of the tank body 1 is provided with a protrusion 14 for accommodating the reinforcing ribs 13. The protrusion 14 is an arc-shaped protrusion used to provide clearance space for the lifting movement of the reinforcing ribs 13 and avoid interference between the reinforcing ribs 13 and the top surface of the tank body 1.

[0028] Specifically, the drive assembly includes a movable frame 15 movably mounted on the top surface of the tank 1 and lifting units symmetrically mounted on the outer side wall of the tank 1. The movable frame 15 is used to fix the hollow tube 2 and drive the hollow tube 2 to move up and down synchronously. The lifting unit includes a strip box 16, a screw 17, a guide rod 18, and a lifting arm 21. The strip box 16 is fixedly mounted on the outer side wall of the tank 1. The screw 17 is rotatably mounted inside the strip box 16 and is driven by a second motor mounted at the bottom of the strip box 16. The screw 17 is used to convert the rotational motion of the second motor 22 into linear motion. A screw sleeve 19 is also installed on the screw 17. The inner wall of the screw sleeve 19 is provided with an internal thread that precisely meshes with the external thread of the screw 17, so as to drive the lifting arm 21 to move up and down when the screw 17 rotates.

[0029] The guide rod 18 is fixedly installed inside the strip box 16 and arranged parallel to the screw 17. The guide rod 18 is a cylindrical rigid rod, which is used to guide the movement of the sliding sleeve 20 and the lifting arm 21 and prevent the lifting arm 21 from deviating. The sliding sleeve 20 is movably arranged on the guide rod 18. The sliding sleeve 20 can slide flexibly along the guide rod 18 to assist in supporting the lifting arm 21 and ensure that the lifting arm 21 moves smoothly. The lifting arm 21 passes through the top surface of the strip box 16 and is fixedly connected to the bottom surface of the movable frame 15. The lifting arm 21 is fixedly arranged between the screw sleeve 19 and the sliding sleeve 20 to connect the screw sleeve 19, the sliding sleeve 20 and the movable frame 15, transmit the lifting power and drive the movable frame 15 to move up and down synchronously.

[0030] Working principle:

[0031] When it is necessary to clean the tank 1, first empty the semi-finished edible oil in the tank 1, then start the second motor 22 of the drive assembly. The second motor 22 drives the screw 17 in the strip box 16 to rotate. The screw 17 is threadedly engaged with the screw sleeve 19, which drives the screw sleeve 19 to move downward along the screw 17. At the same time, the sliding sleeve 20 slides downward along the guide rod 18. The screw sleeve 19 and the sliding sleeve 20 together drive the lifting arm 21 to move downward. The lifting arm 21 drives the movable frame 15 to move downward, which in turn drives the hollow tube 2 and the lifting seat 3 to move downward. The cleaning components on the lifting seat 3 also move downward together.

[0032] At this time, the external pump body is started, and the pump body delivers the cleaning fluid through the delivery pipe 11 to the annular pipe 10 inside the lifting seat 3. The annular pipe 10 evenly distributes the cleaning fluid to each nozzle 9. The nozzle 9 is tilted towards the silicone scraper ring 6 to spray the cleaning fluid, which wets and pre-cleans the inner wall of the tank on the one hand, and cleans the silicone scraper ring 6 simultaneously on the other hand.

[0033] As the lifting seat 3 moves downward, the silicone scraper ring 6 on the outer ring of the scraper 4 closely adheres to the inner wall of the tank, simultaneously scraping away the grease residue and impurities attached to the inner wall of the tank, achieving a thorough cleaning of the inner wall of the tank. When the lifting seat 3 moves to the bottom of the tank 1, the silicone scraper strip 8 on the bottom surface of the rotating part 5 comes into close contact with the bottom surface of the inner cavity of the tank 1. At this time, the first motor 7 is started, and the first motor 7 drives the rotating part 5 to rotate slowly. The rotating part 5 drives multiple silicone scraper strips 8 to rotate synchronously. The silicone scraper strips 8 scrape away the residual impurities on the bottom surface of the tank 1. Combined with the cleaning fluid sprayed by the nozzle 9, the bottom surface of the tank is thoroughly cleaned. The wastewater generated during cleaning can be discharged through the drain port at the bottom of the tank 1.

[0034] After cleaning is completed, the second motor is started in reverse, which drives the screw 17 to rotate in the opposite direction. Then, through the screw sleeve 19, sliding sleeve 20, lifting arm 21 and movable frame 15, the hollow tube 2, lifting seat 3 and cleaning components are driven to return to the top of the tank 1, and the pump body and the first motor 7 are turned off.

[0035] When filling tank 1 with oil, the level of the semi-finished oil is controlled to be lower than the height of the cleaning components to avoid oil contact with the cleaning components and causing contamination. At the same time, it also prevents the cleaning components from being contaminated with oil, ensuring the subsequent cleaning effect and the quality of the semi-finished oil. The entire cleaning process does not require manual entry into the tank, has a high degree of automation, and is simple and quick to operate, completely solving the problems of cumbersome, time-consuming and labor-intensive cleaning of existing oil storage tanks.
