Description

Technical Field

[0001] This utility model relates to the field of soybean processing technology, specifically to a pulp and residue separation device for deep processing of soybeans. Background Technology

[0002] In the field of soybean deep processing, pulp-residue separation is one of the core steps in the production of soybean products (such as soy milk, tofu, and soybean flour). In traditional processes, soybeans are soaked and ground to form a pulp-residue mixture, which needs to be separated by physical means to extract the pulp and remove the soybean residue. Early separation technologies mainly relied on gravity natural filtration or manual pressing, which had problems such as low efficiency, large pulp residue, and high labor intensity. With the increase in industrial demand, mechanical filtration devices have gradually become more widespread, but existing technologies still have significant limitations.

[0003] Currently, most mainstream soybean pulp and residue separation equipment adopts a single-layer bottom filtration structure, such as the "Soybean Pulp and Residue Separation Device for Deep Processing" disclosed in Chinese Utility Model Patent CN215203593U. This device includes a support base, a slurry collection platform, and a hinged arc-shaped protective cover. Its core filtration component is a bottom metal filter screen. During operation, the pulp and residue mixture is placed above the filter screen, and the slurry permeates downwards by gravity or simple mechanical compression, while the soybean residue accumulates on the screen surface. However, this type of design has the following drawbacks: Single filtration path: filtration is only carried out through the bottom filter screen in one direction. The flow rate of the slurry is limited by the area and porosity of the filter screen, which is prone to clogging, especially when processing high-viscosity slurry, resulting in low separation efficiency (measured efficiency is less than 50%); High slurry residue rate: After unidirectional extrusion, some slurry is retained in the soybean residue layer due to gravity back-seepage, making it difficult to separate completely, with a raw material waste rate as high as 15%-20%; Structural limitations: The bottom filter screen is fixedly installed, making disassembly and maintenance difficult, and it lacks dynamic pressure adjustment function, making it unable to adapt to the processing needs of slurry residue with different particle sizes or moisture contents.

[0004] To address the aforementioned issues, the industry urgently needs an innovative solution that can overcome the limitations of unidirectional filtration and achieve multi-channel separation. By introducing an upper and lower dual-channel filtration design, the slurry outflow path is expanded and dynamic extrusion control is enhanced, which can significantly improve separation efficiency and resource utilization while reducing equipment maintenance costs.

[0087] Working principle:

[0088] This device achieves efficient separation of soybean pulp residue through a combination of mechanical extrusion and double-layer filtration. Its core principle is:

[0089] Dual-channel filtration: The top filter plate 33 and the filter screen 21 of the filter element 2 work simultaneously. The slurry is discharged through the top separation hole 331 and the bottom screen, which expands the filtration area and improves the separation efficiency.

[0090] Dynamic pressure control: The multi-stage telescopic cylinder 31 drives the top filter plate to press down, applying controllable pressure to the slurry. The elastic reset component 5 buffers the pressure impact, ensuring the stability of the extrusion process.

[0091] Splash prevention and guiding design: After the splash plate 322 is fixed, it forms a sealed space to prevent slurry from splashing; the auxiliary guide rod 61 ensures that the filter plate moves vertically and avoids deviation that would lead to uneven filtration.

[0092] The functions of each component are as follows:

[0093] Separation Tank 1: As the core container for slurry-sludge separation, it provides a closed space for physical compression and filtration.

[0094] Top opening 11: Used for adding soybean pulp residue, making it easy to operate.

[0095] Conical receiving zone: The slurry after separation is concentrated by gravity and guided to the discharge port to reduce slurry residue.

[0096] Discharge port 12 and control valve 13: control the discharge speed of slurry and achieve accurate collection of slurry after separation.

[0097] Support legs 15 and stabilizing plate 16: Ensure the stability of the device and prevent tilting due to pressure or vibration during operation. The support legs increase the contact area and are suitable for high-load conditions.

[0098] Filter cartridge 2: As the main filtration unit, it intercepts soybean residue and allows the slurry to pass through.

[0099] Filter screen 21: The aperture is designed to be 0.1-0.3mm to achieve physical separation of slurry and soybean residue.

[0100] Side wall guide rod 22: The guide groove embedded in the inner wall of the separation barrel ensures that the filter element moves vertically and avoids displacement.

[0101] Convenient handle 23 and end connector 24: quick disassembly design for easy cleaning of residue or replacement of filter screen.

[0102] Top extrusion component 3: Accelerates slurry separation through mechanical pressure, achieving dual-channel filtration.

[0103] Multi-stage telescopic cylinder 31: Provides controllable linear power to drive the top filter plate downward.

[0104] Top connector 32: connects the power source telescopic cylinder to the actuator filter plate, transmitting pressure and ensuring stability.

[0105] Separation hole 331: Auxiliary filter screen to increase the slurry outflow path.

[0106] Inclined flow surface 332: guides the top slurry to flow towards the periphery of the separation tank, avoiding accumulation.

[0107] Fixing component 4 and elastic reset component 5: Modular quick-release design reduces downtime, and elastic reset avoids hard collisions.

[0108] Movable block 41 and quick insertion block 42: The inclined contact surface 421 realizes self-locking during insertion, and the spring 44 provides insertion stability.

[0109] Pull handle 43: Manual operation for quick release of the filter plate, facilitating maintenance.

[0110] Spring 252: The high-elasticity stainless steel material provides stable restoring force, ensuring the splash guard springs back to its original position.

[0111] Auxiliary guide component 6: It has a dual function of guiding and limiting, which improves the safety of the extrusion process.

[0112] Auxiliary guide rod 61: threaded connection to the top filter plate 33, ensuring vertical movement trajectory and preventing deviation.

[0113] Limiting plate 62: Limits the travel of guide rod 61 to prevent excessive pressure from damaging the filter element.

[0114] The detailed workflow is as follows:

[0115] S1, Preparation Phase

[0116] S11, Device inspection: Confirm that there are no residues in the separation tank 1, the filter element 2 and the top filter plate 33 are installed in place, and the control valve 13 is closed.

[0117] S12, Start the equipment: The multi-stage telescopic cylinder 31 retracts, and the top filter plate 33 rises to its highest point, freeing up space for feeding.

[0118] S2, Feeding

[0119] S21, Pour in the pulp residue: Pour the soybean pulp residue into the filter element 2 through the opening 11 at the top of the separation tank. The pulp residue accumulates on the filter screen 21.

[0120] S3, splash-proof fixing

[0121] S31, splash guard docking: Start the multi-stage telescopic cylinder 31 to slowly press down, driving the top connector 32 to descend. The docking blocks 323 around the splash guard 322 are precisely docked with the docking groove 17 on the inner wall of the separation tank, locking the position of the splash guard 322 and forming a closed space at the top to prevent slurry from splashing.

[0122] S4, Extrusion Separation

[0123] S41, Initial Pressing: The multi-stage telescopic cylinder 31 continues to extend, the spring 52 of the elastic reset member 5 begins to compress, and the top filter plate 33 contacts the slurry surface.

[0124] S42, Dynamic Extrusion: The top filter plate 33 continuously presses down, applying uniform pressure to the slurry residue, and the slurry is discharged through the following path:

[0125] S421, Upper discharge: Part of the slurry flows out from the separation hole 331 of the top filter plate 33, is guided along the inclined flow surface 332 to the perimeter wall of the separation tank 1, and flows into the bottom receiving area.

[0126] S422, Lower layer discharge: The remaining slurry penetrates the filter screen 21 and flows directly into the conical receiving area.

[0127] S5, Slurry Collection

[0128] S51, Collection and Discharge: The separated slurry collects at the bottom of the conical receiving area and flows to the discharge port 12 by gravity. The control valve 13 is opened to adjust the flow rate and introduce the slurry into the external container.

[0129] S6, Residue Treatment

[0130] S61, Lifting extrusion component: Multi-stage telescopic cylinder 31 retracts, top filter plate 33 rises, splash guard 322 resets with elastic reset component 5.

[0131] S62, Remove the filter element: Lift the filter element 2 with the convenient handle 23, and the side guide rod 22 slides out along the guide groove. The remaining soybean residue in the separation bucket is removed along with the filter element.

[0132] S63, Cleaning soybean residue: Remove filter element 2, pour out or rinse the soybean residue on the filter screen, and prepare for the next use.

[0133] S7, Cleaning and Maintenance
