Description

Technical Field

[0001] This utility model relates to the field of potato starch extraction technology, specifically a potato starch extraction and filtration device. Background Technology

[0002] Potatoes, also known as yam, are herbaceous plants belonging to the Solanaceae family and the Solanum genus. They can grow up to 80 cm tall, are hairless or sparsely pubescent, and have tuberous underground stems that are flat and round or oblong. The tubers are rich in starch and can be eaten. They are one of the staple foods in mountainous areas and a major raw material for the starch industry. The newly sprouted shoots and fruits are rich in solanine, which is the raw material for extracting solanine. Potatoes are also the fourth most important food crop in the world, after wheat, rice, and corn, and can also be used as a vegetable.

[0003] When using this method, potato slurry needs to be poured into a coarse sieve placed above the container for filtration. It is then repeatedly rinsed and rubbed with water to allow the starch milk to flow through the sieve into the container below, while the coarse residue remains on the sieve. However, the accumulation of potato slurry on the top of the sieve can prevent filtration. Therefore, a potato starch extraction and filtration device is proposed to solve the aforementioned problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a potato starch extraction and filtration device to address the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a potato starch extraction and filtration device, including a filter box, a filter screen frame inside the filter box, and a roller pressing mechanism inside the filter box. The roller pressing mechanism includes an electric push rod, which is fixedly connected to the inner wall of the filter box. A fixed plate is fixedly connected to the left side of the electric push rod, and a gate-shaped plate is fixedly connected to the bottom of the fixed plate. A rotating rod moves through the interior of the gate-shaped plate and extends to its front and rear sides. A pressure roller is fixedly connected to the outer wall of the rotating rod. When the electric push rod is activated, the telescopic rod of the electric push rod pushes the fixed plate and the gate-shaped plate connected thereto to reciprocate horizontally. The gate-shaped plate slides in the groove of the filter screen frame through a slider at its bottom, ensuring a smooth movement trajectory. While the gate-shaped plate moves horizontally, it drives the pressure roller to move laterally, reciprocatingly rolling and crushing the potato pulp accumulated on the filter screen frame. This action directly and proactively flattens and thins the piled-up potato slurry, spreading it evenly on the screen surface, completely changing the traditional method where the potato slurry piles up below the feed inlet.

[0006] Preferably, a first spring is sleeved on the outer wall of the rotating rod, the first spring is disposed between the gate-shaped plate and the pressure roller, and a corrugated groove is formed on the inner wall of the filter box, the corrugated groove being in contact with the rotating rod.

[0007] Preferably, the filter screen frame has an internal groove, and a slider is slidably connected inside the groove. The slider is fixedly connected to a portal plate. As the portal plate moves horizontally, the two ends of a rotating rod fixedly connected to the portal plate roll in a corrugated groove on the inner wall of the filter box. Due to the undulating contour of the corrugated groove, the rotating rod is forced to produce a vertical displacement while moving horizontally, thereby driving the pressure roller to compress or release the first spring, producing an up-and-down undulating motion. Ultimately, the combined motion trajectory of the pressure roller is a combination of horizontal reciprocating motion and vertical vibration, which, while rolling and crushing the potato pulp on the screen surface, periodically knocks and vibrates the pulp. During its undulating movement, the pressure roller generates strong rolling pressure on the accumulated potato pulp, forcibly squeezing and separating the starch particles from the fibers. The separated starch milk passes through the sieve holes of the filter screen frame under pressure, completing the extraction. At the same time, the vibration of the pressure roller helps prevent the potato pulp from caking and shakes off surface adhering substances.

[0008] Preferably, the filter box is provided with a puncturing mechanism, which includes a vertical rod fixedly connected to the inside of the filter box. A square plate is fitted on the outer wall of the vertical rod, and a puncturing rod is fixedly connected to the top of the square plate. A second spring is fitted on the outer wall of the vertical rod.

[0009] Preferably, there are two vertical rods and two second springs, which are arranged on the left and right sides inside the filter box.

[0010] Preferably, the second spring is disposed between the bottom of the square plate and the filter box. A protrusion is fixedly connected to the bottom of the square plate, and an abutment rod is fixedly connected to the front of the gate-shaped plate. The abutment rod contacts the protrusion, and the abutment rod fixed to its front moves synchronously during the horizontal movement of the gate-shaped plate. When the abutment rod moves to below the protrusion of the abutment mechanism, it will push the protrusion upward. When the protrusion is pushed up, it will cause the square plate to compress the second spring and slide upward along the vertical rod. The abutment rod fixed to the top of the square plate moves upward, and its tip pierces into the screen hole of the filter screen frame from bottom to top, pushing out the fiber impurities blocking the hole and realizing the clearing of the blockage. When the gate-shaped plate continues to move, causing the abutment rod to separate from the protrusion, the square plate and the abutment rod move downward rapidly under the restoring force of the second spring, disengaging from the screen hole and returning to the initial position, ready for the next abutment.

[0011] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0012] 1. This potato starch extraction and filtration device, driven by an electric pusher, reciprocates and rolls the potato slurry piled on the filter screen frame. This action directly and actively flattens and thins the piled-up slurry, spreading it evenly on the screen surface. This completely changes the traditional method where the slurry piles up below the feed inlet. Furthermore, the pressure roller moves in a corrugated groove via a rotating rod and can float up and down under the action of a first spring. Its periodic undulation effectively breaks the initial caking tendency of the slurry, preventing the formation of dense, difficult-to-handle lumps.

[0013] 2. This potato starch extraction and filtration device utilizes the reciprocating motion of a piercing rod to push upwards onto the screen from below. This action powerfully breaks down the "caking layer" formed by potato pulp fibers at the top of the screen, disrupting the fiber structure and releasing the starch granules trapped inside. This creates a channel for the starch to pass through the screen, fundamentally solving the filtration stagnation problem caused by material clumping. During the upward movement, the piercing rod directly penetrates and loosens the fiber clumps clogging the screen holes, achieving physical unblocking from the back of the screen. This is an extremely efficient and direct unclogging method, especially suitable for processing potato pulp with high fiber content and a tendency to stick together. Attached Figure Description

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 component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" means two or more, unless otherwise explicitly specified.

[0023] Please see Figure 1-4One embodiment of this utility model is: a potato starch extraction and filtration device, including a filter box 1, a filter screen frame 2 is provided inside the filter box 1, and a roller pressing mechanism 3 is provided inside the filter box 1. The roller pressing mechanism 3 includes an electric push rod 311, which is fixedly connected to the inner wall of the filter box 1. A fixing plate 312 is fixedly connected to the left side of the electric push rod 311, and a gate-shaped plate 313 is fixedly connected to the bottom of the fixing plate 312. A rotating rod 314 is movably passed through the interior of the gate-shaped plate 313 and extends to its front and rear sides. A pressure roller 319 is fixedly connected to the outer wall of the rotating rod 314. When the electric push rod 311 is activated, the telescopic rod of the electric push rod 311 pushes the fixing plate 312 and the gate-shaped plate 313 connected thereto to reciprocate in the horizontal direction. The portal plate 313 slides within the groove 317 of the filter screen frame 2 via the slider 318 at its bottom, ensuring a smooth movement trajectory. As the portal plate 313 moves horizontally, it drives the pressure roller 319 to move laterally, reciprocatingly rolling and crushing the potato pulp accumulated on the filter screen frame 2. This action directly and actively flattens and thins the piled-up potato slurry, spreading it evenly on the screen surface. This completely changes the traditional method where the potato slurry accumulates below the feed inlet. A first spring 315 is fitted on the outer wall of the rotating rod 314, and is positioned between the gate plate 313 and the pressure roller 319. A corrugated groove 316 is formed on the inner wall of the filter box 1, which contacts the rotating rod 314. A sliding groove 317 is formed inside the filter screen frame 2, and a slider 318 is slidably connected inside the sliding groove 317. The slider 318 is fixedly connected to the gate plate 313. As the gate plate 313 moves horizontally, both ends of the rotating rod 314, which is fixedly connected to the gate plate 313, roll in the corrugated groove 316 on the inner wall of the filter box 1. Due to the undulating contour of the corrugated groove 316, the rotating rod 314 is forced to produce a vertical displacement while moving horizontally, thereby driving the pressure roller 319 to compress or release the first spring 315, producing an up-and-down undulating motion. Ultimately, the combined motion trajectory of the pressure roller 319 is a combination of horizontal reciprocating motion and vertical vibration. While rolling and pressing the potato pulp on the screen surface, it also periodically strikes and vibrates the pulp. During its undulating movement, the pressure roller 319 generates strong rolling pressure on the accumulated potato pulp, forcibly squeezing and separating the starch granules from the fibers. The separated starch milk passes through the sieve holes of the filter screen frame 2 under pressure, completing the extraction. Simultaneously, the vibration of the pressure roller 319 helps prevent the potato pulp from clumping and shakes off surface adhering substances.

[0024] Working principle: When the electric push rod 311 is activated, its telescopic rod pushes the fixed plate 312 and the connected portal plate 313 to reciprocate horizontally. The portal plate 313 slides within the groove 317 of the filter screen frame 2 via its bottom slider 318, ensuring a smooth movement trajectory. Simultaneously, the portal plate 313 drives the pressure roller 319 to move laterally, reciprocatingly rolling and pressing the potato slurry accumulated on the filter screen frame 2. This action directly and actively flattens and thins the accumulated potato slurry, spreading it evenly on the screen surface, completely changing the traditional method where the potato slurry accumulates below the feed inlet.

[0025] As the portal plate 313 moves horizontally, the two ends of the rotating rod 314, fixedly connected to the portal plate 313, roll in the corrugated groove 316 on the inner wall of the filter box 1. Due to the undulating contour of the corrugated groove 316, the rotating rod 314 is forced to produce a vertical displacement while moving horizontally, thereby driving the pressure roller 319 to compress or release the first spring 315, producing an up-and-down undulating motion. Ultimately, the combined motion trajectory of the pressure roller 319 is a combination of horizontal reciprocating motion and vertical vibration, which causes it to periodically knock and vibrate the potato pulp on the screen surface while rolling and crushing it. During its undulating movement, the pressure roller 319 generates strong rolling pressure on the accumulated potato pulp, forcibly squeezing and separating the starch particles from the fibers. The separated starch milk passes through the sieve holes of the filter screen frame 2 under pressure, completing the extraction. At the same time, the vibration of the pressure roller 319 helps to prevent the potato pulp from caking and shake off surface adhering substances.

[0026] Please see Figure 1-4Based on the above embodiments, in another embodiment of the present invention, a poking mechanism 4 is provided inside the filter box 1. The poking mechanism 4 includes a vertical rod 411, which is fixedly connected to the inside of the filter box 1. A square plate 413 is sleeved on the outer wall of the vertical rod 411. A poking rod 414 is fixedly connected to the top of the square plate 413. A second spring 412 is sleeved on the outer wall of the vertical rod 411. There are two vertical rods 411 and two second springs 412, which are arranged on the left and right sides inside the filter box 1. The second spring 412 is arranged between the square plate 413 and the bottom of the filter box 1. A protrusion 416 is fixedly connected to the bottom of the square plate 413. An abutment rod 415 is fixedly connected to the front of the door-shaped plate 313. The abutment rod 415 contacts the protrusion 416. During the horizontal movement of the door-shaped plate 313, the abutment rod 415 fixed to its front moves synchronously. When the abutment rod 415 moves below the protrusion 416 of the abutment mechanism 4, it pushes the protrusion 416 upward. When the protrusion 416 is pushed up, it causes the square plate 413 to compress the second spring 412 and slide upward along the vertical rod 411. The abutment rod 414, fixed to the top of the square plate 413, moves upward accordingly, and its tip pierces into the screen hole of the filter screen frame 2 from bottom to top, pushing out the fiber impurities blocking the hole and clearing the blockage. When the gate plate 313 continues to move, causing the abutment rod 415 to separate from the protrusion 416, the square plate 413 and the abutment rod 414 move downward rapidly under the restoring force of the second spring 412, disengaging from the screen hole and returning to the initial position, ready for the next abutment.

[0027] Working principle: During the horizontal movement of the gate-shaped plate 313, the abutment rod 415 fixed to its front moves synchronously. When the abutment rod 415 moves below the protrusion 416 of the abutment mechanism 4, it pushes the protrusion 416 upward. When the protrusion 416 is pushed up, it causes the square plate 413 to compress the second spring 412 and slide upward along the vertical rod 411. The abutment rod 414 fixed to the top of the square plate 413 moves upward, and its tip pierces into the screen hole of the filter screen frame 2 from bottom to top, pushing out the fiber impurities blocking the hole and realizing the clearing of the blockage. When the gate-shaped plate 313 continues to move, causing the abutment rod 415 to separate from the protrusion 416, the square plate 413 and the abutment rod 414 move downward rapidly under the restoring force of the second spring 412, disengaging from the screen hole and returning to the initial position, ready for the next abutment.

[0028] This utility model provides a potato starch extraction and filtration device. There are many methods and approaches to implement this technical solution. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model. All components not explicitly stated in this embodiment can be implemented using existing technology.
