Technical Field
[0001] This utility model relates to the field of edible oil pressing and processing, specifically a cleaning device for edible oil physical pressing equipment. Background Technology
[0002] In the physical pressing process of edible oil production, raw materials such as soybeans, peanuts, and rapeseed are squeezed by the pressing structure, producing a large amount of oil and material residue. These substances easily adhere to key parts of the pressing equipment, such as the pressing chamber, pressing rod, and oil filter components. Due to the significant differences in flavor and composition among different varieties of edible oil and the extremely high requirements for purity, if the residual oil and impurities in the equipment are not thoroughly cleaned, they will deteriorate due to oxidation and microbial growth over a long period of time. This will not only produce off-odors but may also breed harmful substances. When pressing other varieties of raw materials in the future, the deteriorated residues will mix into the new oil, destroying its flavor and quality and even affecting food safety. At the same time, the accumulation of impurities can also clog the gaps in the equipment, reduce pressing efficiency, and shorten the service life of the equipment. Therefore, thorough cleaning of the pressing equipment is a key step in ensuring the quality of edible oil and the continuity of production. However, current cleaning methods for edible oil physical pressing equipment have significant drawbacks, failing to meet the demands for efficient and thorough cleaning. Existing equipment often features integrated or bolted-fixed pressing structures, requiring the machine to be stopped before cleaning. Specialized tools are then used to disassemble components such as the pressing chamber and filter plates, a cumbersome and time-consuming process that severely impacts production efficiency. This is especially true in scenarios requiring frequent changes in the type of raw material being pressed, where the time cost of disassembly and cleaning significantly increases the production cycle. Furthermore, manual disassembly and cleaning can only target the exterior and easily removable parts of the equipment, failing to thoroughly clean hidden areas such as dead corners inside the pressing chamber and gaps between the pressing rods. Therefore, a cleaning device for edible oil physical pressing equipment needs to be designed to address these issues. Utility Model Content
[0003] The purpose of this invention is to provide a cleaning device for edible oil physical pressing equipment to solve the problems mentioned in the background art.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Example 1 Please refer to Figure 1-6 As shown, this utility model provides a cleaning device for a physical pressing equipment of edible oil, including a support frame 1 of the pressing equipment. A motor 2 is fixedly installed at the bottom of the support frame 1 by bolts. A fixed plate 3 is installed on the output shaft of one side of the motor 2. The fixed plate 3 is connected to the driven plate 5 by a belt 4. A feeding rack 6 is installed at the top of the support frame 1. A connecting shaft 7 passes through the inner side of the feeding rack 6. A pressing shaft 8 is fixedly installed at one end of the connecting shaft 7 by bolts. The connecting shaft 7 is fixedly connected to the driven plate 5. A pressing component for processing materials is installed inside the feeding rack 6. A cleaning component for cleaning residual materials is installed outside the pressing shaft 8. A connector for connecting an external conduit is installed at the end of the pressing shaft 8.
[0017] In addition, motor 2 can drive driven disc 5 to rotate via belt 4 on the outside of fixed disc 3. Driven disc 5 drives pressing shaft 8 to rotate rapidly via connecting shaft 7. Pressing shaft 8 can drive pressing components to push and press materials. The cleaning components on the outside of pressing shaft 8 can wash away residual impurities and oil with high-pressure water flow. The connector at one end of pressing shaft 8 can be installed and fixed with external conduit without affecting the normal rotation of pressing shaft 8. Therefore, the rapid rotation of connecting shaft 7 and pressing shaft 8 during the washing process allows the aqueous solution to self-clean the connecting shaft 7 and pressing shaft 8, improving the efficiency and thoroughness of the cleaning operation and preventing impurities and oil from remaining on the inside of pressing frame 9.
[0018] Specifically, the pressing component includes a pressing frame 9 bolted to one side of the feeding frame 6, a pressing part 10 integrally formed on the outer side of the pressing shaft 8 near one end, a mating strip 11 welded to the inner side of the pressing frame 9, and a pushing strip 12 welded to the outer side of the pressing shaft 8 and the outer side of the pressing part 10.
[0019] The pressing section 10 has a diameter larger than the pressing shaft 8, and there is a connecting part between the pressing section 10 and the pressing shaft 8 to facilitate the material to be guided to the outside of the pressing section 10. Both the mating strip 11 and the pushing strip 12 are spiral-shaped. The pushing strip 12 on the outside of the pressing shaft 8 can push and guide the material. The pushing strip 12 on the outside of the pressing section 10 and the mating strip 11 can squeeze the material to extract oil. The pressed oil is discharged separately as solid and liquid through the pressing frame 9, which improves the efficiency of the equipment in pressing oil from the material.
[0020] More specifically, the cleaning component includes a guide cavity 13 located inside the press shaft 8, a plurality of circumferentially arranged water spray chambers 14 located outside the guide cavity 13, a sliding rod 15 slidably connected inside the water spray chambers 14, a sealing block 16 integrally formed on the top of the sliding rod 15, a pad 17 additionally provided outside the sliding rod 15 near the bottom, a spring 18 fixedly connected between the pad 17 and the water spray chambers 14, a plurality of circumferentially arranged water spray holes 19 located on the top of the water spray chambers 14, a guide strip 23 welded inside the guide cavity 13, a plurality of circumferentially arranged fixing strips 24 welded outside the pusher strip 12, and a plurality of scraper strips 25 fixedly installed on one side of the fixing strips 24.
[0021] In addition, the guide cavity 13 can be connected to a hot water solution and pressurized. The spring 18 in the spray cavity 14 can squeeze the pad 17, causing the pad 17 to drive the sealing block 16 at the top of the sliding rod 15 to seal the spray hole 19 at the top of the spray cavity 14. When the water pressure is high, it pushes the pad 17, so that the water can flow through the spray cavity 14 and the spray hole 19 to spray out and wash the inner wall of the press frame 9 and the feeding frame 6. The guide strip 23 in the guide cavity 13 can guide the water flow and accelerate the water flow rate. The pusher strip 12 can drive the scraper 25 to rotate quickly on the inner wall of the feeding frame 6 through the fixing strip 24, so that the scraper 25 can scrape and clean the impurities and oil on the inner wall of the feeding frame 6. The water solution in the feeding frame 6 and the press frame 9 can quickly wash the press shaft 8 to avoid the residue of impurities and oil inside the equipment.
[0022] Furthermore, the connector includes a retaining ring 20 screwed to one end of the press shaft 8, a connecting ring 21 for connecting the water guide pipe 22 is fitted on the outside of the retaining ring 20 and rotatably connected, and a flow guide portion 26 is welded to the inner ring of the connecting ring 21.
[0023] The fixing ring 20 is screwed to one end of the pressing shaft 8. The connecting ring 21 can rotate with the outside of the fixing ring 20. The outside of the connecting ring 21 can be connected and fixed to the water guide pipe 22 without affecting the normal rotation of the pressing shaft 8. The flow guide part 26 of the inner ring of the connecting ring 21 can guide and seal the water flow, preventing water overflow caused by gaps between the connecting ring 21 and the inner ring of the flow guide cavity 13.
[0024] Working principle: First, the fixing ring 20 is screwed to one end of the pressing shaft 8. Then, the external water pipe 22 is screwed to the connecting ring 21 or flanged. Then, the flow guide part 26 of the inner ring of the connecting ring 21 fits into the inner ring of the flow guide cavity 13. Then, high-pressure hot water is flushed into the flow guide cavity 13. At the same time, the high-pressure water pushes the pad 17 upward and the pad 17 squeezes the spring 18. Then, the sliding rod 15 in the pad 17 pushes the sealing block 16 away from the spray chamber 14. Then, the water flows out through the spray chamber 14 and the spray hole 19 to wash the inner wall of the pressing frame 9 and the feeding frame 6. Next, start motor 2, which drives driven disc 5 to rotate via belt 4 on the outside of fixed disc 3. At this time, driven disc 5 drives pressing shaft 8 to rotate rapidly via connecting shaft 7. At this time, push bar 12 drives scraper 25 to rotate rapidly on the inner wall of feeding rack 6 via fixed bar 24. At this time, scraper 25 scrapes and cleans impurities and oil on the inner wall of feeding rack 6. At the same time, the aqueous solution in feeding rack 6 and pressing rack 9 quickly washes pressing shaft 8.
