Description

Technical Field

[0001] This utility model relates to the field of press cleaning technology, and in particular to a quick-release press chamber cleaning structure for rapeseed oil presses. Background Technology

[0002] A rapeseed oil press is a specialized mechanical device that extracts vegetable oil from rapeseed using physical pressure. Its core process involves using strong mechanical pressure to squeeze pre-treated rapeseed, causing the oil to separate and overflow from the cell structure. During operation, the rapeseed raw material is subjected to continuous pressure within a sealed space. The oil flows out through specific channels, while the residue after defatting forms a cake-like byproduct. The entire pressing process is carried out at room temperature or a suitable temperature, effectively preserving the natural nutrients and flavor compounds of the oil, making it a key piece of equipment in the edible oil processing industry.

[0003] Cleaning the pressing chamber is crucial for ensuring oil quality and production efficiency. During rapeseed oil pressing, oil residue easily adheres to the inner wall of the pressing chamber and oil leakage seams. Long-term residue will oxidize, clump, and breed mold, leading to increased acid value, rancid odor, and a 30%–50% reduction in shelf life. Simultaneously, residual residue can clog oil outlet channels, reducing oil yield by more than 15%, and exacerbating wear on the inner wall of the pressing chamber, shortening equipment lifespan. Furthermore, cleaning removes impurities such as metal shavings mixed in during pressing, preventing equipment malfunctions. However, existing cleaning methods have significant drawbacks: they mostly rely on manual entry into the pressing chamber to clean with scrapers and brushes. But the inner wall of the pressing chamber has narrow oil leakage seams, making it difficult for manual tools to reach these dead corners, resulting in high residue rates. This manual entry not only poses a risk of mechanical injury, but also takes 1–2 hours per batch, severely impacting production continuity. Moreover, the oil residue mixed with oil is highly adhesive, making it impossible to completely remove by hand wiping; repeated accumulation forms stubborn oil stains, further complicating the cleaning process.

[0004] In response to this technical problem, this application proposes a quick-release pressing chamber cleaning structure for rapeseed oil presses. Utility Model Content

[0005] In order to address the significant drawbacks of existing manual cleaning methods, such as difficulty in reaching blind spots, incomplete cleaning, long processing time, and safety risks, this application provides a quick-release pressing chamber cleaning structure for rapeseed oil presses.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A quick-release pressing chamber cleaning structure is used in a rapeseed oil press, including a pressing chamber body. Multiple oil outlet grooves are opened in the middle of the pressing chamber body, and an oil cylinder is installed at its bottom. A pressing plate, which fits against the inner wall of the pressing chamber body, is fixedly connected to the top of the oil cylinder. During the pressing process, the pressing plate is driven upwards by the oil cylinder, thereby cooperating with the external top plate to press the rapeseed material. A mounting plate is detachably connected to the top of the pressing chamber body via a fixing bolt. The bottom of the mounting plate is connected to the top side of the pressing plate via a limiting assembly. Two sliding rods pass through the mounting plate, and a mounting plate is fixedly connected to the bottom of each sliding rod. A scraper ring is connected to the mounting plate via a positioning assembly to scrape away residue adhering to the inner wall of the pressing chamber body when the pressing plate slides up and down.

[0007] As a further improvement of this utility model, the positioning group includes a rod that passes through the inner wall of the mounting plate, a clamping plate is provided at the bottom of the rod, and the top of the rod is fixed to the top side of the mounting plate by a screw sleeve, so as to form a quick-release clamping mechanism, which facilitates the quick replacement or fixation of the scraper ring.

[0008] As a further improvement of this utility model, the scraper ring is located on the side of the mounting plate and the clamping plate, and its inner side is provided with a through hole that matches the insertion rod, so as to ensure that the scraper ring is stably clamped and aligned with the inner wall of the pressing chamber, thereby effectively dispersing the circumferential stress generated during the scraping operation.

[0009] As a further improvement of this utility model, the limiting group includes support columns fixedly connected to both ends of the bottom side of the mounting plate and a limiting block fixedly connected to the top side of the extrusion plate. The bottom side of the support column is provided with a slot that matches the limiting block.

[0010] As a further improvement of this utility model, the top ends of the slide bars on both sides are connected by a handle to provide the operator with a concentrated point of force for manual assistance or independent pulling of the scraper ring for cleaning operations.

[0011] As a further improvement of this utility model, an oil collecting hopper is provided on the outer wall of the pressing chamber body, and an oil outlet pipe is provided at the outer end of the oil collecting hopper to collect the oil flowing out of the oil outlet trough and guide it out of the press.

[0012] As a further improvement of this utility model, the top side of the mounting plate is provided with multiple through slots to reduce the overall weight of the component and save materials, while facilitating observation of the internal cleaning status and component movement.

[0013] As a further improvement of this utility model, the sliding rod and the mounting plate are slidably fitted at the insertion point to ensure that the cleaning mechanism frame formed by the sliding rod and the mounting plate can move stably along the axial direction of the pressing chamber body, providing precise motion guidance for the scraper ring.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: This invention employs a modular design concept, enabling the rapid separation and integration of the cleaning function with the main operating system. This feature eliminates the need for routine cleaning and maintenance in complex machine environments, significantly reducing equipment downtime and substantially improving overall maintenance efficiency.

[0015] In this invention, the unique connection and fixing method makes the replacement of vulnerable parts exceptionally simple. After cleaning the wear of parts, operators can complete the replacement in a short time without the need for special tools or professional technicians. This not only reduces maintenance costs but also minimizes equipment downtime losses caused by parts replacement.

[0016] In this invention, a precise guiding mechanism ensures that the cleaning components always move along the optimal path, effectively preventing deviation or jamming during movement. This feature guarantees the comprehensiveness and uniformity of the cleaning operation, avoiding the blind spots that may exist in traditional cleaning methods, thereby maintaining high-quality cleaning results.

[0025] like Figures 1-4As shown, the rapeseed oil press uses a quick-release pressing chamber cleaning structure, including a pressing chamber body 1. Multiple oil outlet grooves 2 are opened in the middle of the pressing chamber body 1, and an oil cylinder is installed at its bottom. A pressing plate 5, which is fixedly connected to the top of the oil cylinder and fits against the inner wall of the pressing chamber body 1, is used to push upwards under the drive of the oil cylinder during the pressing process, thereby cooperating with the external top plate to squeeze the rapeseed material. A mounting plate 7 is detachably connected to the top of the pressing chamber body 1 via a fixing bolt 8. This detachable connection facilitates the quick installation and disassembly of the entire cleaning module. The bottom of the mounting plate 7 is connected to the top side of the pressing plate 5 via a limiting group. This limiting group can effectively transmit pressure during the pressing process and plays a guiding role during cleaning. Two sliding rods 10 are passed through the mounting plate 7. A mounting plate 11 is fixedly connected to the bottom of the sliding rods 10. A scraper ring 16 is connected to the mounting plate 11 via a positioning group to scrape off the residue adhering to the inner wall of the pressing chamber body 1 when the pressing plate 5 slides up and down, achieving efficient cleaning. Example

[0026] like Figures 2-4 As shown, the positioning assembly includes a rod 12 that passes through the inner wall of the mounting plate 11. A clamping plate 14 is provided at the bottom of the rod 12, and the top of the rod 12 is fixed to the top side of the mounting plate 11 by a threaded sleeve 13 to form a quick-release clamping mechanism, which facilitates the quick replacement or fixing of the scraper ring 16. This design greatly improves the efficiency of scraper ring 16 maintenance. The scraper ring 16 is located on the side of the mounting plate 11 and the clamping plate 14, and its inner side is provided with a through hole 15 that matches the rod 12, so as to ensure that the scraper ring 16 is stably clamped and aligned with the inner wall of the pressing chamber body 1, thereby effectively dispersing the circumferential stress generated during the scraping operation and extending the service life of the scraper ring 16. The limiting assembly includes support columns 6 fixedly connected to both ends of the bottom side of the mounting plate 7 and limiting blocks 18 fixedly connected to the top side of the extrusion plate 5. The bottom side of the support columns 6 has slots that fit the limiting blocks 18. This structure ensures a reliable connection between the extrusion plate 5 and the mounting plate 7, and provides accurate movement guidance for the cleaning mechanism. The top ends of the two sliding rods 10 are connected by a handle 17 to provide a concentrated force point for the operator, facilitating manual assistance or independent pulling of the scraper ring 16 for cleaning operations when needed, thus enhancing operational convenience. An oil collecting hopper 3 is provided on the outer wall of the pressing chamber body 1 to collect oil. An oil outlet pipe 4 is provided at the outer end of the oil hopper 3 to collect the oil flowing out of the oil outlet trough 2 and guide it out of the press to prevent oil spillage. Multiple through slots 9 are provided on the top side of the mounting plate 7 to reduce the overall weight of the component and save materials, while facilitating observation of the internal cleaning status and component movement. The sliding rod 10 and the mounting plate 7 are slidably fitted to ensure that the cleaning mechanism frame formed by the sliding rod 10 and the mounting plate 11 can move stably along the axial direction of the pressing chamber body 1, providing precise motion guidance for the scraper ring 16, preventing the scraper ring 16 from tilting, and ensuring a uniform and thorough cleaning effect.

[0027] Working principle: After the pressing operation is completed, the operator first installs the mounting plate 7 on the top of the pressing chamber body 1 using the fixing bolts 8. At this time, the support column 6 at the bottom of the mounting plate 7 is connected to the limiting block 18 on the top side of the extrusion plate 5 through the slot on its bottom side. During the cleaning operation, the operator holds the handle 17 and pulls the slide rod 10 up and down. The slide rod 10 drives the mounting plate 11 at the bottom and the scraper ring 16 fixed by the insert rod 12, clamp 14 and screw sleeve 13 to move axially along the pressing chamber body 1. At this time, the edge of the scraper ring 16 contacts the inner wall of the pressing chamber and scrapes off the residual oil residue. The scraped residue falls on the extrusion plate 5, and the residual oil falls into the oil collection hopper 3 through the oil outlet 2 and is finally discharged from the oil outlet pipe 4. Throughout the process, the sliding cooperation between the slide rod 10 and the mounting plate 7 ensures the stable movement of the scraper ring 16, while the through groove 9 on the mounting plate 7 facilitates the observation of the internal cleaning situation. After the cleaning is completed, the fixing bolts 8 can be loosened to quickly disassemble the entire cleaning module and complete the entire cleaning process.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
