Description

Technical Field

[0001] The utility model relates to the field of oil presses, and more specifically, to an anti-clogging oil press. Background Art

[0002] Cold-pressed oil presses use mechanical force to separate the oil from the crude oil. The entire process is performed without heating or at low temperatures, preventing the damage to the oil's nutrients caused by high temperatures. This process preserves the active substances and nutrients in the oil, such as vitamin E and sterols, resulting in cold-pressed oil with higher nutritional value and health benefits. However, the feed hopper of existing cold-pressed oil presses is difficult to break up after the first press cycle. During the second and third press cycles, the cake easily clogs the feed hopper, hindering the feed.

[0003] For example, patent number CN202221143952.5 discloses an anti-clogging low-temperature oil press. During the use of this device, the material enters the equipment through the hopper and is stirred inside the hopper by the contact plate. At the same time, the adjustable baffle controls the falling speed of the material. However, the function of the contact plate is only to stir the material. When faced with a large amount of accumulated oil cakes, the contact plate cannot crush the cakes in time, resulting in the oil being easily blocked at the feed port, which greatly affects the oil pressing efficiency of the oil press.

[0033] like Figure 1 The anti-clogging oil press shown in the figure comprises: an oil press body 1, a screw shaft 3 for squeezing material is disposed in a pressing chamber 2 inside the oil press body 1, a feed hopper 4 is disposed above the oil press body 1, the bottom of the feed hopper 4 is connected to a discharge pipe 5, a discharge auxiliary component 6 is disposed in the discharge pipe 5, a spiral feeding component 7 for transferring cake to the feed hopper 4, and a cake crushing component 8 disposed at the outlet of the feeding component;

[0034] The discharge port 15 of the spiral feeding assembly 7 is located directly above the feed hopper 4 .

[0035] Working principle:

[0036] The material (oil-bearing crop seeds) is placed into the feed hopper 4 above the oil press body 1. Once the material enters the feed hopper 4, it flows through the discharge tube 5 at the bottom into the press chamber 2 of the oil press. The auxiliary discharge assembly 6 in the discharge tube 5 helps the material fall smoothly, quickly and evenly into the press chamber 2, avoiding blockage and agglomeration. Inside the press chamber 2, the spiral shaft 3 begins to rotate, strongly squeezing and crushing the material. The spiral shaft 3 causes the material to be gradually compressed as it moves forward, and the oil and fat inside are squeezed out and collected through the oil outlet of the oil press. During this process, the material gradually turns into cake, which is transferred to the oil press directly above the feed hopper 4 through the spiral feeding assembly 7 at the discharge port of the oil press. A cake crushing assembly 8 is provided at the outlet to break the large cake into smaller particles or powder for subsequent reuse or processing. The crushed cake falls directly into the feed hopper 4 through the feeding assembly, is mixed with new materials and squeezed again, and the cake crushing assembly 8 further reduces the size of the cake and reduces the risk of blockage.

[0037] In the above technical solution, the spiral feeding assembly 7 includes: a feeding pipe I 71 matched with the discharge port of the oil press, and a feeding spiral 73 arranged inside the vertical pipeline of the feeding pipe I 71;

[0038] a feeding pipe II 72 connected to the top of the feeding pipe I 71;

[0039] The cake crushing assembly 8 includes: an active crushing roller 81 and a driven crushing roller 82 arranged side by side at the discharge port 15 of the feeding pipe II 72;

[0040] The discharge port 15 of the feeding pipe II 72 is located just above the feed hopper 4. This technical method is used, wherein the feeding pipe I 71 is spatially distributed as a vertical upward pipeline. The bottom of the feeding pipe I 71 is connected to the discharge port of the oil press through a connecting pipe. A feeding screw 73 is installed inside the vertical pipeline of the vertical feeding pipe I 71. The top of the feeding pipe is provided with a feeding pipe II 72 with a downward tilt angle. The active crushing roller 81 and the driven crushing roller 82 are provided at the discharge port 15 of the feeding pipe II 72. During the working process, after the initial The cake formed from the secondary pressing enters the connecting pipe through the discharge port. The cake then passes through the bottom motor of the feeding screw 73, which drives the feeding screw 73 to rotate and lift the cake from a low position (the discharge port of the oil press) to a high position (directly above the feed hopper 4). Finally, it passes through the inclined feeding pipe II 72 and falls between the active crushing roller 81 and the driven crushing roller 82 at the discharge port 15. The cake is simultaneously squeezed and sheared by the active crushing roller 81 and the driven crushing roller 82. This dual action effectively breaks large cake into smaller particles or powder, making it easier to reuse or process.

[0041] In the above technical solution, the auxiliary unloading assembly 6 includes a motor mounted on the side wall of the unloading tube 5. A rotating shaft 9, which is rotated forward and reversely by the motor, is provided through the outer wall of the unloading tube 5. A plurality of unloading plates 10 are evenly distributed along the circumference of the rotating shaft 9. With this technical solution, the rotation of the motor drives the rotation of the rotating shaft 9, causing the unloading plates 10 to rotate within the unloading tube 5. This can impact the material during unloading, accelerate its descent, and avoid material accumulation and subsequent blockage.

[0042] In the above technical solution, the motor is configured as a variable frequency motor. With this technical solution, the influence on the falling speed of the material can be controlled by controlling the different speeds of the motor.

[0043] In the above technical solution, the blanking plate 10 is configured as a fan-shaped or spiral structure with multiple different angles. With this technical solution, the fan-shaped or spiral structure can increase the contact area between the blanking plate 10 and the material during rotation, thereby enhancing the process of material falling.

[0044] In the above technical solution, the pitch of the spiral blades at the front end of the spiral shaft 3 is greater than the pitch of the spiral blades at the rear end, and the diameter of the rear end of the spiral shaft 3 gradually decreases in the direction of the discharge port. With this technical solution, the pitch of the spiral blades at the front end is larger, and the front end can handle more materials. This helps to quickly crush and squeeze the material in the initial stage of entering the pressing chamber 2, thereby improving the efficiency of the entire oil pressing process. As the material gradually moves backward, the pitch of the spiral blades at the rear end decreases, making the extrusion process tighter and more delicate, ensuring that the oil is fully squeezed out. The diameter of the rear end of the spiral shaft 3 gradually decreases, which helps to optimize the flow of the material in the pressing chamber 2. As the material is gradually compressed, its volume decreases, and a smaller space is required to accommodate it. The reduction in the diameter at the rear end provides the necessary compression space for the material, ensuring that the material can move forward smoothly while reducing the risk of blockage.

[0045] In the above-mentioned technical solution, a squeezing portion 11 is provided in the middle of the spiral shaft 3; the outer surface of the squeezing portion 11 is provided with evenly distributed arc-shaped protrusions 12. With this technical solution, the arc-shaped protrusions 12 on the squeezing portion 11 directly contact the material during the rotation of the spiral shaft 3, creating a multi-point, uniform squeezing effect. This design not only increases the contact area for squeezing, but also, through the shape of the protrusions, makes the squeezing force more concentrated and effective. Therefore, it can more deeply disrupt the material structure, promote the precipitation of oil, and improve oil extraction efficiency. The coordination between the spiral blades provided on the spiral shaft 3 and the squeezing portion 11 ensures more complete crushing and squeezing of the material.

[0046] In the above technical solution, at least two buffer baffles 13 are hinged relative to each other in the height direction at the opening of the feed hopper 4; wherein, a buffer spring 14 is provided between the buffer baffle 13 and the feed hopper 4. With this technical solution, when materials are poured into the feed hopper 4, especially when the material flow rate is large or the particles are large, they may hit the bottom or side wall of the feed hopper 4 at a relatively fast speed, generating a large impact force. The provision of the buffer baffle 13 can effectively mitigate this impact force, allowing the material to enter the feed hopper 4 more smoothly, reducing impact damage to the feed hopper 4 and subsequent equipment. Because buffer springs 14 are provided between the buffer baffle 13 and the feed hopper 4, these springs can expand and contract to a certain extent according to the weight and impact force of the material. This expansion and contraction effect can indirectly adjust the feed speed of the material, allowing the material to enter the pressing chamber 2 of the oil press more evenly, avoiding the problem of blockage caused by excessive feed speed.

[0047] In the above technical solution, the feeding pipe I 71 and the feeding pipe II 72 are connected to the oil press body 1 via a supporting component 16;

[0048] Among them, the feeding pipe I71 and the discharge port and the feeding pipe I71 and the feeding pipe II72 are respectively connected by flanges 17. With this technical solution, the feeding pipe I71 and the feeding pipe II72 are firmly connected to the oil press body 1 by using the support component 16, which can ensure the stability and safety of the pipeline during the material transportation process. The support component 16 can not only effectively disperse the weight of the pipeline, but also the flange 17 connection is detachable, which facilitates the installation, disassembly and maintenance of the pipeline. When the pipeline needs to be cleaned or parts need to be replaced, it can be easily completed by loosening the bolts. The flange 17 connection can adapt to the connection requirements of pipelines of different specifications and materials. By selecting the appropriate flange 17 and sealing gasket, the tightness and reliability of the connection can be ensured.

[0049] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
