Description

Technical Field

[0001] This utility model relates to the field of solid-liquid separation technology for soybean products, specifically a solid-liquid separation device for soybean product production. Background Technology

[0002] Solid-liquid separation is a crucial step in the production of soy products, directly impacting product quality and production efficiency. However, traditional solid-liquid separation equipment for soy products suffers from numerous technical shortcomings, making it difficult to meet the demands of high-efficiency production. Currently, the mainstream separation methods mostly rely on manual extrusion or simple filtration devices. Manual extrusion is not only labor-intensive but also results in uneven force application, leading to excessive liquid residue in the soy products and significant resource waste. Simple filtration devices are mostly single-layer filtration structures with insufficient filtration precision, leaving a large number of fine solid particles in the separated liquid, affecting the quality of subsequent processing.

[0003] Meanwhile, traditional equipment suffers from poor cleaning convenience: most filter components are fixedly connected to the main body of the equipment, requiring disassembly for residue cleaning, which is cumbersome, time-consuming, and prone to production interruptions; some devices lack reasonable liquid guidance and collection structures, causing liquid to splash during separation, resulting in waste and pollution of the production environment. In addition, traditional equipment has limited adaptability, making it difficult to accommodate different forms of soy product raw materials, and filter components are prone to clogging during separation, requiring frequent shutdowns for cleaning, further reducing production efficiency and failing to meet the batch, high-efficiency, and high-quality production needs of small and medium-sized soy product enterprises.

[0018] 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. Example

[0019] Please refer to the following: Figure 1-4 , A solid-liquid separation device for soybean product production, comprising: The base plate 1, U-shaped rod 2, water guide frame 3 and four support columns 4 are fixedly installed on the top of the base plate 1, the water guide frame 3 is fixedly installed on the top of the base plate 1, and the four support columns 4 are fixedly installed on the top of the base plate 1. The water guide plate 5, the filter screen 6, and the four insert rods 7 are provided. The water guide plate 5 is movably attached to the top of the four support columns 4. The filter screen 6 is fixedly installed on the top of the water guide plate 5. The four insert rods 7 are fixedly installed on the bottom of the water guide plate 5, and the insert rods 7 are movably connected to the support columns 4. The filter plate 8 is movably inserted inside the filter screen 6, and filter cotton is provided on the outside of the filter plate 8. Hydraulic rod 9 and pressure frame 10 are provided. The hydraulic rod 9 is fixedly installed on the outside of the U-shaped rod 2, and the pressure frame 10 is fixedly installed on the output end of the hydraulic rod 9. The pressure frame 10 is located directly above the filter screen 6. Specifically, the base plate 1, U-shaped rod 2, water guide frame 3, and support columns 4 are as follows: The base plate 1 is the reference load-bearing structure of the device, providing a fixed installation platform for all components such as the U-shaped rod 2, water guide frame 3, and support columns 4, ensuring the overall stability of the device during separation and preventing displacement caused by squeezing and vibration; the U-shaped rod 2 is fixed to the top of the base plate 1, providing vertical support for the hydraulic rod 9, and reserving working space for the hydraulic rod 9 and pressure frame 10 through a transverse structure, while also enhancing the stability of the hydraulic rod 9 after installation; the water guide frame 3 is fixed to the top of the base plate 1 and serves as a collection carrier for the separated liquid, used to centrally collect the filtered liquid from the bean products, preventing liquid splashing and environmental pollution; the four support columns 4 are fixed to the top of the base plate 1, providing support and positioning for the water guide plate 5, ensuring that the water guide plate 5 is horizontal and stable after installation, and limiting the displacement of the water guide plate 5 through cooperation with the insertion rod 7; Water guide plate 5, filter screen 6, and insert rods 7: The water guide plate 5 is movably attached to the top of the support column 4, serving as a liquid flow guide and transition component. After the filtered liquid flows out from the filter screen 6, it is guided into the water guide frame 3 through the water guide plate 5, preventing liquid spillage. The filter screen 6 is fixed to the top of the water guide plate 5, serving as a carrier for placing and initially filtering the raw materials of the bean products. It is used to hold the raw materials of the bean products to be separated, while blocking solid residues and allowing liquid to pass through. The four insert rods 7 are fixed to the bottom of the water guide plate 5 and are movably connected to the support column 4. They are positioning connectors for the water guide plate 5, ensuring that the water guide plate 5 is accurately installed on the support column 4 and facilitating the disassembly of the water guide plate 5, which in turn moves the filter screen 6 and the residue as a whole, enabling convenient cleaning. Filter plate 8: It is movably inserted inside the filter screen 6 and has filter cotton on the outside. It is a high-precision filter element that works with the filter screen 6 to form a dual filtration structure. The filter cotton can further intercept fine solid particles and improve the purity of the separated liquid. The movable insertion and removal design allows the filter plate 8 to be removed separately, which is convenient for cleaning the residual residue on the filter cotton and avoids clogging that affects the filtration efficiency. Hydraulic rod 9 and pressure frame 10: Hydraulic rod 9 is fixed to the outside of U-shaped rod 2 and is the power source for lifting and lowering pressure frame 10. Through hydraulic extension and retraction, pressure frame 10 is driven to move vertically downward, applying squeezing pressure to the raw bean product inside filter screen 6; Pressure frame 10 is fixed to the output end of hydraulic rod 9, so that the squeezing actuator is located directly above filter screen 6. When it moves downward, it penetrates into the interior of filter screen 6, squeezing the raw bean product evenly and squeezing out the liquid in the raw material to achieve solid-liquid separation; In this embodiment: the four support columns 4 are arranged in a rectangular shape at the four corners of the top of the base plate 1, and the height of the support columns 4 is greater than the height of the water guide frame 3; Specifically, the four support columns 4 are arranged in a rectangular shape at the top four corners of the base plate 1, which can make the water guide plate 5 evenly stressed and avoid tilting that would cause the liquid to deviate. If the support columns 4 are not symmetrically distributed, the support force on one side of the water guide plate 5 will be insufficient, and it is easy for one side to sink. The liquid will flow unevenly on the water guide plate 5, and some liquid will not be able to flow into the water guide frame 3. The rectangular distribution can evenly transfer the weight of the water guide plate 5 to the four support columns 4, ensuring that the water guide plate 5 always remains horizontal and provides a stable flow path for the liquid. The height of the support column 4 is greater than the height of the water guide frame 3, so as to reserve a flow guiding space between the water guide plate 5 and the water guide frame 3. If the height of the support column 4 is too low, the water guide plate 5 will be close to the top of the water guide frame 3, the liquid flow space will be narrow and easy to stagnate, and the water guide plate 5 will be easy to collide with the water guide frame 3 when it is disassembled; sufficient height can ensure that a smooth flow channel is formed between the water guide plate 5 and the water guide frame 3, and the liquid will flow into the water guide frame 3 quickly, while avoiding component interference when disassembling the water guide plate 5. In the embodiment: the four insertion rods 7 are respectively arranged in a one-to-one correspondence with the four support columns 4, and the outer diameter of the insertion rod 7 is adapted to the inner diameter of the support column 4; Specifically, the insertion rod 7 and the support column 4 are set in a one-to-one correspondence, which can achieve precise positioning of the water guide plate 5. If the insertion rod 7 and the support column 4 are misaligned, the water guide plate 5 will be offset after installation, the filter screen 6 will not be aligned with the pressure frame 10, the force will be uneven when squeezed, and the water guide plate 5 will deviate from the water guide frame 3. The one-to-one correspondence can make the water guide plate 5 quickly find the installation position, ensure that the filter screen 6 and the pressure frame 10 are coaxial, and the water guide plate 5 and the water guide frame 3 are precisely connected, reducing the installation and adjustment time. The outer diameter of the insert rod 7 is adapted to the inner diameter of the support column 4, which can achieve a tight and movable connection. If the gap is too large, the water guide plate 5 will easily shake after installation and the filter screen 6 will shift during squeezing, affecting the separation effect. If the gap is too small, the insert rod 7 is difficult to insert or pull out, and disassembly and cleaning are inconvenient. The matching size allows the water guide plate 5 to be stably installed on the support column 4 without displacement during squeezing. At the same time, disassembly can be done simply by lifting the water guide plate 5 upwards, which is convenient. In this embodiment: the top surface of the water guide plate 5 is inclined, and the lowest end of the water guide plate 5 corresponds to the top end of the water guide frame 3; Specifically, the top surface of the water guide plate 5 is inclined to accelerate the flow of liquid using gravity. If the top surface of the water guide plate 5 is horizontal, the liquid flow speed is slow and it is easy to stagnate on the surface of the water guide plate 5, causing residue to be drawn back into the liquid, resulting in low separation efficiency. The inclined design allows the liquid to flow quickly along the inclined surface under the action of gravity, reducing the residence time and improving the liquid collection efficiency. The lowest point of the water guide plate 5 corresponds to the top point of the water guide frame 3 to ensure that the liquid flows accurately into the water guide frame 3. If the lowest point deviates from the water guide frame 3, some liquid may drip from the edge of the water guide plate 5, causing waste and pollution. The corresponding setting allows all the flowing liquid to be concentrated and flow into the water guide frame 3 from the lowest point, realizing complete collection of liquid and avoiding waste. In this embodiment: the inner diameter of the filter screen 6 is adapted to the outer diameter of the filter plate 8, and the height of the filter plate 8 is less than the height of the filter screen 6; Specifically, the inner diameter of the filter screen 6 is matched with the outer diameter of the filter plate 8 to avoid filtration failure caused by gaps. If the gap is too large, fine solid particles will leak out from the gap, reducing the purity of the liquid. If the gap is too small, the filter plate 8 is difficult to insert or remove for cleaning. The matching size allows the filter plate 8 to fit tightly against the inner wall of the filter screen 6, forming a gapless filtration, ensuring that all liquids must pass through the filter cotton and filter screen 6, thus improving filtration accuracy. The height of the filter plate 8 is less than the height of the filter screen 6 to reserve space for raw material placement and compression. If the height of the filter plate 8 is the same as that of the filter screen 6, the top of the filter plate 8 will be flush with the top of the filter screen 6, resulting in insufficient space for raw material placement and the pressure frame 10 being unable to penetrate deeply to compress the liquid, leading to insufficient extrusion. The lower height ensures that there is sufficient space above the filter plate 8 to accommodate the raw material, and the pressure frame 10 can fully compress the raw material when it moves down, while avoiding direct collision between the pressure frame 10 and the filter plate 8, thus protecting the filter plate 8 and the filter cotton. In this embodiment: the outer diameter of the pressure frame 10 is smaller than the inner diameter of the filter screen 6, and the axis of the pressure frame 10 coincides with the axis of the filter screen 6; Specifically, the outer diameter of the pressure frame 10 is smaller than the inner diameter of the filter screen 6, allowing the pressure frame 10 to smoothly penetrate into the filter screen 6. If the outer diameter of the pressure frame 10 is too large, it cannot be inserted into the filter screen 6 and the raw material cannot be squeezed; if it is too small, the squeezing range is limited and liquid at the edge of the raw material cannot be squeezed out. The appropriate size allows the pressure frame 10 to maintain a reasonable gap with the inner wall of the filter screen 6 after penetrating into the filter screen 6, which covers the entire raw material area and avoids collision with the filter screen 6, protecting the filter screen 6 and ensuring that the raw material is evenly compressed. The axis of the pressure frame 10 coincides with the axis of the filter screen 6, which can ensure that the extrusion pressure is transmitted evenly. If the axis is offset, the pressure frame 10 will be biased to one side of the filter screen 6, resulting in excessive pressure on one side of the raw material, excessive extrusion and clumping of local residues, and insufficient pressure on the other side, leaving liquid residue. The coaxial setting allows the pressure frame 10 to apply pressure evenly from the center of the raw material to the surrounding area, so that the liquid in the raw material is fully squeezed out and the solid-liquid separation is more thorough. In this embodiment: the opening of the U-shaped rod 2 faces the water guide frame 3, and the height of the U-shaped rod 2 is greater than the length of the hydraulic rod 9; Specifically, the opening of the U-shaped rod 2 faces the water guide frame 3, which allows the pressure frame 10 to be precisely aligned with the filter screen 6. The cross structure of the U-shaped rod 2, combined with the opening direction, allows the hydraulic rod 9 to face the filter screen 6 directly after installation. The lifting trajectory of the pressure frame 10 always points to the center of the filter screen 6, avoiding the pressure frame 10 from shifting due to installation angle deviation. At the same time, the opening direction does not obstruct the water guide frame 3 and the water guide plate 5, making it convenient to observe the separation process and cleaning operation. The height of U-shaped rod 2 is greater than the length of hydraulic rod 9, allowing sufficient travel for the extension and retraction of hydraulic rod 9. If the height of U-shaped rod 2 is too low, the pressure frame 10 cannot move down to the preset extrusion position when hydraulic rod 9 is fully extended, resulting in insufficient material extrusion. Alternatively, when fully retracted, the pressure frame 10 cannot rise to the high position, affecting material placement and residue cleaning. Sufficient height ensures that hydraulic rod 9 can extend and retract freely, and the pressure frame 10 can move flexibly within its maximum stroke, meeting the requirements for extrusion and avoidance. In this embodiment: the inner wall of the water guide frame 3 is smooth, and the length of the water guide frame 3 is adapted to the length of the water guide plate 5; Specifically, the smooth inner wall of the water guide frame 3 reduces liquid flow resistance and residue. If the inner wall is rough, liquid will easily adhere to the wall surface, causing waste, and the residual liquid will easily breed bacteria. The smooth inner wall allows the liquid to flow quickly, reducing adhesion and residue, and at the same time, it facilitates subsequent cleaning of the water guide frame 3, keeping the device clean and hygienic and in line with food production standards. The length of the water guide frame 3 is adapted to the length of the water guide plate 5 to ensure complete liquid collection. If the water guide frame 3 is too short, the liquid guided by the water guide plate 5 will drip out of the water guide frame 3 and be wasted; if it is too long, the water guide frame 3 will occupy too much space and the device volume will be redundant. The adapted length allows all the liquid guided by the water guide plate 5 to fall into the water guide frame 3, achieving efficient liquid collection while controlling the overall volume of the device. Working principle: Step 1: Equipment Assembly and Raw Material Preparation In the initial state of the device, the hydraulic rod 9 is in a retracted state, and the pressure frame 10 is located at a high position directly above the filter screen 6. First, the core components are assembled: the filter plate 8 is inserted into the filter screen 6, and the inner diameter of the filter screen 6 is adapted to the outer diameter of the filter plate 8. The installation is tight and without gaps, and the filter cotton on the outside of the filter plate 8 is attached to the inner wall of the filter screen 6 to form a double filtration structure. Then, the four insert rods 7 at the bottom of the water guide plate 5 are aligned with the rectangular support columns 4 at the top corners of the base plate 1. The insert rods 7 and the support columns 4 correspond one-to-one and are adapted in size. The water guide plate 5 is placed stably on the top of the support columns 4 to achieve precise positioning of the water guide plate 5. At this time, the top surface of the water guide plate 5 is inclined, and the lowest end corresponds to the top of the water guide frame 3 on the base plate 1, which is ready for liquid guidance. Finally, the raw materials of the bean products to be separated are evenly placed inside the filter screen 6. The raw materials are placed above the filter plate 8. The height of the filter plate 8 is less than the height of the filter screen 6 to leave enough space for the raw materials. Step 2: Hydraulic drive and extrusion separation: The hydraulic rod 9, fixed to the outside of the U-shaped rod 2, is activated. The opening of the U-shaped rod 2 faces the guide frame 3, and its height is greater than the length of the hydraulic rod 9 to avoid interference during compression. The hydraulic rod 9 extends, causing the pressure frame 10 to move vertically downward. Since the outer diameter of the pressure frame 10 is smaller than the inner diameter of the filter screen 6 and its axis is coaxial with the filter screen 6, the pressure frame 10 smoothly penetrates into the filter screen 6 and continuously applies downward compression pressure after contacting the top surface of the bean product raw material. Under the action of pressure, the liquid in the bean product raw material is gradually squeezed out, passes through the filter cotton on the outside of the filter plate 8 for preliminary high-precision filtration, and then passes through the filter screen 6 for secondary filtration, intercepting most of the solid residue and achieving solid-liquid separation. Step 3: Liquid diversion and centralized collection: The filtered liquid from the soy products flows out from the bottom of the filter screen 6 and drips onto the top surface of the water guide plate 5 below. Thanks to the inclined design of the water guide plate 5, the liquid flows rapidly along the inclined surface under the action of gravity, and finally flows precisely into the water guide frame 3 from the lowest end of the water guide plate 5. The inner side wall of the water guide frame 3 is smooth, reducing liquid residue. The water guide frame 3 collects the liquid in a concentrated manner, preventing liquid from splashing or scattering, and facilitating the subsequent recycling of the separated liquid. Step 4: Cleaning of Residue and Components: After solid-liquid separation is completed, the hydraulic rod 9 is reversed to move the pressure frame 10 to its initial high position, separating it from the filter screen 6 area. The operator then pulls the water guide plate 5 upwards, separating the insertion rod 7 from the support column 4, and removes the water guide plate 5, filter screen 6, and internal solid residue from the device as a whole. The residue can then be directly poured out, making the operation convenient. Subsequently, the filter plate 8 can be pulled out from the filter screen 6 to clean the fine residue adhering to the filter cotton separately, preventing the filter holes from becoming clogged. The water guide frame 3 and water guide plate 5 can be wiped clean separately to ensure that there are no residues inside the device, preparing it for the next separation operation.
