Detailed Implementation

[0028] In the accompanying drawings of this utility model, the same or similar reference numerals correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0029] like Figures 1 to 4 As shown, this utility model provides an oil pressing pan, which includes a pan body 10, a material removal component 20, and an oil pan base plate 40. The pan body 10 includes a pan bottom 12 and a pan wall 11 surrounding the pan bottom 12, with a pressing chamber formed between the inner walls of the pan bottom 12 and the pan wall 11. The pan bottom 12 is provided with a through material removal hole 19, and the material removal component 20 is installed on the pan body 10 and slidably connected to the material removal hole 19.

[0030] The material removal assembly 20 includes a material removal plate 22 and a guide post mechanism 23 fixedly connected to the material removal plate 22. The material removal plate 22 is adapted to the shape of the pressing chamber and is laid at the bottom of the pressing chamber. The guide post mechanism 23 slides in the material removal hole 19 to drive the material removal plate 22 to slide in the pressing chamber without causing the material removal plate 22 to detach from the disc body 10.

[0031] The oil pan bottom plate 40 is detachably connected to the pan bottom 12 by fasteners. The stripping plate 22 and the oil pan bottom plate 40 are located on both sides of the pan bottom 12. During the oil pressing process of multiple oil pressing pans stacked together, part of the pan bottom 12 and the oil pan bottom plate 40 of the previous oil pressing pan are inserted into the pressing chamber of the next oil pressing pan. The oil pan bottom plate 40 moves toward the stripping plate 22 in the pressing chamber. Both the oil pan bottom plate 40 and the stripping plate 22 are provided with screen holes 21, which can filter the oil liquid out without introducing oilseed raw materials, thereby improving the purity of the oil liquid.

[0032] The disc wall 11 is arranged around the disc bottom 12, and an assembly step 15 is formed between the lower end face of the disc bottom 12 and the disc wall 11. During the stacking of two oil pressing discs, the lower end face of the disc wall 11 of the previous oil pressing disc can approach or even abut against the top end face of the disc wall 11 of the next oil pressing disc, thereby achieving maximum pressing depth.

[0033] The inner wall of the disc wall 11 can be configured with a gradually increasing opening structure to facilitate the stacking and assembly of the oil pressing discs. Optionally, the difference between the inner diameter of the pressing chamber and the outer diameter of the disc bottom 12 is D, where 1mm≤D≤10mm.

[0034] The disc wall 11 surrounds the disc bottom 12, and the minimum dimension of the bottom of the disc wall 11 is less than or equal to the dimension of the disc bottom 12. The opening dimension of the disc wall 11 is larger than the outer diameter dimension of the disc bottom 12, and the difference between the inner diameter of the pressing chamber and the outer diameter of the disc bottom 12 can be set to 1mm, 2mm, 3mm, 5mm, 6mm, 8mm, or 10mm.

[0035] Furthermore, the disc wall 11 includes a positioning groove 13, multiple oil guiding channels 14, and multiple flow guide grooves 18. The positioning groove 13 is an annular recess at the top of the disc wall 11, and the multiple oil guiding channels 14 extend from the positioning groove 13 to the assembly step 15. The positioning groove 13 has an inwardly recessed guide groove structure, which can connect the top area of ​​the disc wall 11 into a whole, facilitating the collection and flow of oil. The multiple oil guiding channels 14 are evenly distributed around the center line of the oil pressing disc to form a balanced conduction path in all directions.

[0036] The oil guiding channel 14 runs from top to bottom through the disc wall 11, allowing the oil in the positioning groove 13 to flow downwards through the oil guiding channel 14, reducing the probability of oil overflowing outside the disc wall 11 and greatly improving the cleanliness of the oil pressing disc. Furthermore, the oil is not exposed to the external environment, further enhancing cleanliness. The oil guiding channel 14 can connect stacked oil pressing discs, and oil overflowing from its own pressing disc can also flow through the oil guiding channel 14.

[0037] Furthermore, multiple guide channels 18 are partially recessed from the inner wall, with one end of each channel extending to intersect the step surface of the assembly step 15. Located within the pressing chamber, the guide channels 18 allow oil to flow directly through the channels 18 to the lower side of the assembly step 15 for output during pressing, thus achieving multi-path oil output in conjunction with the oil guiding channel 14. All oil converges at the positioning groove 13 of the next pressing disc, achieving secondary balanced flow and greatly improving flow efficiency.

[0038] The perforated plate 30 is plugged into the corresponding guide channel 18, and the perforated plate 30 has multiple oil-passing perforations evenly distributed. The perforated plate 30 filters the oil through the oil-passing perforations, preventing residue from entering the guide channel 18, thus achieving the filtration effect.

[0039] like Figures 1 to 4 As shown, the oil in the pressing chamber is directionally guided by the guide channel 18 to the area below the assembly step 15. When the pressing pans are stacked, the oil directly enters the oil guide channel 14 of the next pressing pan, thereby reducing or even preventing the oil from flowing to the outer surface of the pressing pan. The perforated plate 30 fills the guide channel 18 and filters the residue, improving the purity of the oil. The guide channel 18 and the oil guide channel 14 create a directional flow of oil in the pressing pan, making the flow direction of the pressed oil controllable and reducing oil waste.

[0040] In one embodiment, the assembly step 15 and the positioning groove 13 are located at both ends of the disc wall 11, respectively. Correspondingly, when two adjacent oil pressing discs are stacked, the step surface of the assembly step 15 of the upper oil pressing disc and the positioning groove 13 of the lower oil pressing disc are arranged opposite to each other. The assembly step 15 and the positioning groove 13 form an annular flow guiding space, and the opening of the oil guiding channel 14 is located in the annular flow guiding space. The annular flow guiding space is connected to the oil guiding channel 14, and the annular flow guiding space constitutes an oil buffer space and a space for convergence.

[0041] In one embodiment, the step surface of the mounting step 15 partially protrudes to form a positioning rib 17. The highest point of the protrusion of the positioning rib 17 is located within the projection range of the positioning groove 13. The oil guiding channel 14 connects the positioning groove 13 and the positioning rib 17. On a plane perpendicular to the axis of the oil pressing disc, the projection of the positioning rib 17 is located within the projection range of the positioning groove 13. Correspondingly, the oil in the oil guiding channel 14 is guided by the positioning rib 17 into the positioning groove 13, achieving directional flow.

[0042] In one embodiment, the width of the positioning groove 13 is greater than the width of the positioning rib 17, and the positioning rib 17 gradually decreases in size from the assembly step 15 towards its end. Preferably, the positioning rib 17 is a triangular protrusion, a curved protrusion, or a hemispherical protrusion. The small end size of the positioning rib 17 can guide the oil to converge and change the liquid flow direction.

[0043] The positioning groove 13 has a large groove width, which increases the contact area for oil and thus improves the bearing capacity.

[0044] Furthermore, the positioning rib 17 is provided with an outer conical surface 171, and the positioning groove 13 is provided with a matching inner conical surface 131. The cone angle of the outer conical surface 171 is the same as that of the inner conical surface 131. The outer conical surface 171 and the inner conical surface 131 are complementary conical surface structures. When the outer conical surface 171 and the inner conical surface 131 are closed, they form a sealing surface between two adjacent oil pressing discs, forming a channel space with a closed outer edge and annular flow of internal oil.

[0045] In a preferred embodiment, the height of the inner wall 133 of the positioning groove 13 is less than the height of the outer wall 132 of the positioning groove 13. The two sides of the positioning groove 13 have a height difference, with the outer wall 132 being greater than the inner wall 133, so that even if the oil in the positioning groove 13 flows back towards the inside of the pressing pan, it will not flow out of the pressing pan. The oil guide channel 14 constitutes the main oil output direction of the positioning groove 13, greatly improving the controllability of the oil output range.

[0046] Furthermore, the inner wall 133 of the positioning groove 13 is provided with a plurality of spaced notches 134. These notches 134 connect the positioning groove 13 and the pressing chamber, allowing a portion of the oil extracted from the oilseeds to enter the positioning groove 13 through the notches 134, and then be directionally output through the oil guide channel 14. Simultaneously, the notches 134 further reduce the risk of oil leaking from the outer wall 132 of the positioning groove 13. Optionally, the notches 134 are spaced around the center line of the pressing disc. For example, the number of notches 134 can be set to 10 or more.

[0047] In addition to the oil guide channel 14 also having an output, the oil pressing disc can also directionally discharge oil from the guide channel 18. The perforated screen 30 is installed in the guide channel 18 and can withstand the pressure during the pressing process; the position of the perforated screen 30 will not shift.

[0048] like Figures 2 to 6 As shown, the flow guide trough 18 defines the installation position of the perforated plate 30. In one embodiment, the bottom width of the flow guide trough 18 is greater than the opening width, and the edges of the perforated plate 30 complement the walls of the flow guide trough 18. The flow guide trough 18 can be configured with a T-shaped, dovetail-shaped, or trapezoidal cross-section to restrict the perforated plate 30 from being pulled out of the opening of the flow guide trough 18. The flow guide trough 18 extends to the mounting step 15, and the perforated plate 30 can be inserted and tightly fitted into the flow guide trough 18 from the opening of the mounting step 15, thereby achieving lateral flow guidance of the perforated plate 30. Preferably, the perforated plate 30 is configured as a mesh plate.

[0049] As the main flow channel of the oil pressing discs, the oil channel 14 is particularly important when multiple oil pressing discs are stacked and pressed, as the oil from multiple discs converges, requiring improved oil flow efficiency. Therefore, the cross-sectional area of ​​the oil channel 14 needs to be increased to cover the flow area of ​​the disc wall 11.

[0050] In one embodiment, on the circumference of the center line of the oil guide channel 14, the ratio of the sum of the arc lengths of the oil guide channel 14 to the circumference is set to K, where 0.25≤K≤0.5. The oil guide channel 14 can be configured as a circular hole or an arc-shaped hole to penetrate the upper and lower ends of the disk wall 11.

[0051] Multiple oil guiding channels 14 have their centerlines on the same diameter, and adjacent oil guiding channels 14 are separated by walls. To maximize the flow efficiency and channel area of ​​the oil guiding channels 14, as many oil guiding channels 14 as possible are provided, while maintaining the structural strength of the oil pressing disc. The arc length of the oil guiding channel 14 is slightly larger than its diameter; correspondingly, the circumference is the virtual circumference corresponding to the diameter of the centerline of the oil guiding channel 14 on the oil pressing disc.

[0052] The sum of the arc lengths of all oil guide channels 14 is the channel space occupied by the oil guide channel 14 on the disk wall 11. The larger the value of K, the larger the conduction area of ​​the oil guide channel 14. For example, K can be set to 0.25, 0.3, 0.35, 0.4, 0.45, or 0.5.

[0053] The discharge plate 22 is located at the bottom of the pressing chamber. It can support and lift the oilseeds and also push the pressed residue out of the pressing chamber. The discharge plate 22 has multiple screen holes 21 that pass through it and a guide screen groove 221 on the back. The screen holes 21 are microporous and can filter and drain the oil.

[0054] The guide mesh trough 221 is located on the back side of the stripper plate 22 to facilitate rapid oil flow. To improve oil flow efficiency, preferably, the guide mesh trough 221 includes concentrically distributed annular grooves 2211 and radially radiating grooves 2212, which intersect with the annular grooves 2211. The annular grooves 2211 consist of multiple concentric circles, and the radial grooves 2212 have multiple radial structures, thus forming a network-type flow channel. This not only expands the flow area but also creates an overhead structure, maintaining support and providing high resistance to bending and torsion.

[0055] Preferably, the structure of the oil pan base plate 40 is basically the same as that of the stripper plate 22. The oil pan base plate 40 is provided with a guide mesh groove 221 and multiple screen holes 21. The difference is that the oil pan base plate 40 is provided with clearance holes, which surround the stripper hole 19. The oil pan base plate 40 is locked to the pan bottom 12 by fasteners, thereby achieving a fixed connection.

[0056] The guide mesh 221 is attached to the bottom surface of the pressing chamber, and the guide mesh 221 is connected to the guide channel 18. The guide mesh 221 can guide the oil into the guide channel 18, so that the oil in the pressing pan can be output through the top oil guiding channel 14 of the pan wall 11 and the bottom side guide channel 18, resulting in high oil output efficiency.

[0057] Furthermore, the length of the perforated plate 30 is less than the depth of the guide groove 18 within the pressing chamber; the opening height between the perforated plate 30 and the bottom surface of the pressing chamber is less than the thickness of the discharge plate 22. The perforated plate 30 is inserted into the guide groove 18, with one end of the perforated plate 30 abutting against the top wall of the guide groove 18, while the lower end of the perforated plate 30 has a perforated area between it and the guide groove 18. This perforated area communicates with the guide mesh groove 221, thereby enabling rapid oil outflow.

[0058] In one embodiment, a stacking groove 16 is provided on the outer side of the disc wall 11, and the oil guiding channel 14 and the stacking groove 16 are distributed at intervals. The stacking groove 16 has a ring structure, which facilitates the stacking of oil pressing discs. The stacking groove 16 and the assembly step 15 are spaced apart to reduce mutual interference.

[0059] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of this application and include common knowledge or customary technical means in the art that are not disclosed in this invention.
