Description

Technical Field

[0001] This utility model relates to the technical field of seaweed extract separation devices, and in particular to a seaweed extract separation device. Background Technology

[0002] In the production of seaweed extracts, solid-liquid separation is a crucial step determining the purity and production efficiency of the extract. The mixture formed after seaweed is crushed, enzymatically hydrolyzed, or fermented contains a large amount of incompletely degraded seaweed residue, fibrous material, and other solid impurities. These impurities need to be separated from the liquid extract through a filtration device. Traditional filtration processes often use filter cloth, filter cartridges, or simple metal filter screens as the separation medium, but these methods have many technical limitations in practical applications.

[0003] Because the seaweed extract mixture is rich in viscous components such as polysaccharides and proteins, solid impurities easily accumulate on the surface of the filter media, forming a filter cake layer and causing rapid clogging of the filter pores. This clogging significantly increases liquid flow resistance, causing filtration efficiency to drop sharply over time. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a seaweed extract separation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a seaweed extract separation device, comprising a filter tank with a hollow cavity structure, an assembly part for solid-liquid separation is provided in the inner cavity of the filter tank, and a scooping part for removing filter residue is provided at the upper part of the inner cavity of the filter tank. The assembly part includes a gasket fixed circumferentially along the inner wall of the filter tank, a metal filter plate is mounted on the top surface of the gasket, and a ring-shaped sealing support ring is fixed circumferentially on the top surface of the gasket. The sealing support ring is made of rubber. Under its own weight, the metal filter plate presses the sealing support ring downward to cause the sealing support ring to undergo elastic deformation to achieve a sealing fit between the metal filter plate and the gasket ring.

[0006] Preferably, a plurality of mounting rods are fixedly fixed at intervals along the circumference of the top surface of the gasket, and mounting holes are opened on the surface of the metal filter plate corresponding to the positions of the mounting rods. A limit ring is fixed on the outer circumferential surface of each mounting rod. The limit ring is interference-fitted with the mounting hole, and the mounting rod passes through the mounting hole to realize the positioning and assembly of the metal filter plate on the gasket.

[0007] Preferably, a circumferential sealing ring is fixed on the outer peripheral side of the metal filter plate. When the metal filter plate is placed in the filter tank, the circumferential sealing ring abuts against the inner wall of the filter tank, and the metal filter plate squeezes the circumferential sealing ring under the action of gravity, causing the circumferential sealing ring to undergo elastic deformation to achieve a sealing fit between the metal filter plate and the inner wall of the filter tank.

[0008] Preferably, the inner wall of the filter tank is provided with an annular groove along the circumferential direction that is adapted to the circumferential sealing ring. The circumferential sealing ring is embedded in the annular groove, and the annular groove and the circumferential sealing ring are interference-fitted to further enhance the sealing effect between the metal filter plate and the inner wall of the filter tank.

[0009] Preferably, the scooping unit includes a motor fixed to the upper part of the outer wall of the filter tank. A lead screw is rotatably connected to the upper part of the filter tank along its length. One end of the lead screw passes through the side wall of the filter tank and is coaxially fixedly connected to the output end of the motor. It also includes two guide blocks spaced apart along the length of the filter tank. One of the guide blocks has a threaded hole in its middle. The guide block is threaded onto the outer circumferential surface of the lead screw through the threaded hole. Each guide block has a groove on its opposite side. A connecting frame is inserted into both grooves. A mesh scooping frame is fixedly connected to the bottom end of the connecting frame. The bottom end of the mesh scooping frame is in contact with the top surface of the metal filter plate. When the motor drives the lead screw to rotate, the guide block moves along the axial direction of the lead screw, causing the mesh scooping frame to slide on the top surface of the metal filter plate to scoop out the accumulated debris.

[0010] Preferably, another guide block has a guide hole in the middle, and a guide rod is slidably inserted into the guide hole. The two ends of the guide rod are respectively fixed to the upper part of the inner wall of the two sides of the filter tank, and the guide rod is arranged parallel to the lead screw to guide the movement of the guide block.

[0011] Preferably, a pin is inserted into the side of the guide block along a direction perpendicular to the movement direction of the guide block, and one end of the pin passes through the side wall of the guide block and extends into the interior of the connecting frame in sequence, so as to realize the detachable fixing of the connecting frame and the guide block.

[0012] Preferably, a spring is fitted on the outer circumferential surface of the pin, one end of the spring is fixedly connected to the outer wall of the guide block, and the other end is fixedly connected to the end of the pin away from the connecting frame. The spring is always in a stretched state to provide an elastic force that keeps the pin inserted into the connecting frame.

[0013] Preferably, a number of supports are fixed at intervals along the circumference of the bottom end of the filter pool, and each support is arranged perpendicular to the bottom surface of the filter pool to support the filter pool.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, the mesh scooping frame effectively cleans debris from above the metal filter plate, preventing debris from accumulating and clogging the filter holes. This keeps the filter holes clear, ensuring that the liquid components in the seaweed extract mixture can continuously and efficiently pass through the filter holes to complete solid-liquid separation and maintain stable separation efficiency.

[0017] Example 1, such as Figure 1-4As shown, a seaweed extract separation device includes a filter tank 1 with a hollow cavity structure. An assembly part for solid-liquid separation is provided inside the inner cavity of the filter tank 1. A scooping part for removing filter residue is provided at the upper part of the inner cavity of the filter tank 1. The assembly part includes a gasket 3 fixed circumferentially along the inner wall of the filter tank 1. A metal filter plate 2 is mounted on the top surface of the gasket 3. A ring-shaped sealing support ring 4 is fixed circumferentially on the top surface of the gasket 3. The sealing support ring 4 is made of rubber. Under its own weight, the metal filter plate 2 presses downward against the sealing support ring 4, causing the sealing support ring 4 to elastically deform to achieve a sealing fit between the metal filter plate 2 and the gasket 3. Several assembly uprights 5 are fixed at intervals along the circumferential direction on the top surface of the gasket 3. The surface of the metal filter plate 2... Assembly holes 7 are provided at the positions corresponding to the assembly uprights 5. Each assembly upright 5 has a limiting ring 6 fixed to its outer circumferential surface. The limiting ring 6 is interference-fitted with the assembly hole 7. The assembly upright 5 passes through the assembly hole 7 to achieve positioning and assembly of the metal filter plate 2 on the gasket 3. A circumferential sealing ring 8 is fixed to the outer circumferential side of the metal filter plate 2. When the metal filter plate 2 is placed in the filter tank 1, the circumferential sealing ring 8 abuts against the inner wall of the filter tank 1. Under the action of gravity, the metal filter plate 2 squeezes the circumferential sealing ring 8, causing the circumferential sealing ring 8 to undergo elastic deformation to achieve a sealing fit between the metal filter plate 2 and the inner wall of the filter tank 1. A groove is provided circumferentially on the inner wall of the filter tank 1 to fit the circumferential sealing ring 8. The circumferential sealing ring 8 is embedded in the groove. The sealing ring 8 is interference-fitted to further enhance the sealing effect between the metal filter plate 2 and the inner wall of the filter tank 1. The scooping part includes a motor 9 fixed to the upper part of the outer wall of the filter tank 1. A lead screw 10 is rotatably connected to the upper part of the filter tank 1 along its length. One end of the lead screw 10 passes through the side wall of the filter tank 1 and is coaxially fixedly connected to the output end of the motor 9. It also includes two guide blocks 11 spaced apart along the length of the filter tank 1. One of the guide blocks 11 has a threaded hole in its middle. The guide block 11 is threaded onto the outer circumferential surface of the lead screw 10 through the threaded hole. Each guide block 11 has a groove on its opposite side. A connecting frame 12 is inserted into both grooves. A mesh scooping frame 13 is fixedly connected to the bottom end of the connecting frame 12. The bottom end of the mesh scooping frame 13 is connected to... The top surfaces of the metal filter plates 2 are in contact with each other. When the motor 9 drives the lead screw 10 to rotate, the guide block 11 moves axially along the lead screw 10, causing the mesh scooping frame 13 to slide on the top surface of the metal filter plate 2 to scoop out the accumulated debris. Another guide block 11 has a guide hole in its middle, and a guide rod 14 is slidably inserted into the guide hole. The two ends of the guide rod 14 are respectively fixed to the upper part of the inner walls on both sides of the filter tank 1. The guide rod 14 is arranged parallel to the lead screw 10 to guide the movement of the guide block 11. A pin 15 is inserted into the side of the guide block 11 perpendicular to the direction of movement of the guide block 11. One end of the pin 15 passes through the side wall of the guide block 11 and extends into the interior of the connecting frame 12 to achieve detachable fixing between the connecting frame 12 and the guide block 11.A spring 16 is fitted onto the outer circumferential surface of the pin 15. One end of the spring 16 is fixedly connected to the outer wall of the guide block 11, and the other end is fixedly connected to the end of the pin 15 away from the connecting frame 12. The spring 16 is always in a stretched state to provide elastic force that keeps the pin 15 inserted into the connecting frame 12. Several supports 17 are fixedly fixed at intervals along the circumference of the bottom end of the filter tank 1. Each support 17 is arranged perpendicular to the bottom surface of the filter tank 1 to support the filter tank 1.

[0018] Working principle: After the seaweed extract mixture enters the filter tank 1, the liquid component of the seaweed extract permeates through the metal filter plate 2 under the action of gravity. The filter pores of the metal filter plate 2 intercept the solid seaweed residue in the mixture, allowing the liquid extract to pass through the filter pores and be separated from the solid residue. The liquid extract is collected at the bottom of the filter tank 1. In the assembly section, the metal filter plate 2 compresses the rubber sealing ring 4 and the circumferential sealing ring 8 under its own weight. With the interference fit between the limiting ring 6 and the assembly hole 7, and the ring groove and the circumferential sealing ring 8, unfiltered seaweed mixture can be prevented from seeping out from the gaps between the metal filter plate 2 and the gasket ring 3, and the inner wall of the filter tank 1, ensuring that all liquid extracts are filtered by the filter plate and improving the separation purity. When excessive seaweed solid residue accumulates on the metal filter plate 2, it can easily clog the filter holes and affect separation efficiency. At this time, the motor 9 is activated, driving the lead screw 10 to rotate. The guide block 11, threaded onto the lead screw 10, moves axially along the lead screw 10, while another guide block 11 moves synchronously along the parallel guide rod 14. This causes the connecting frame 12 and the bottom mesh scooping frame 13 to slide on the top surface of the metal filter plate 2, scraping out the accumulated seaweed residue, ensuring unobstructed filter holes, and maintaining a continuous and efficient separation process. The pin 15 is stably inserted into the connecting frame 12 under the tension of the spring 16, ensuring structural stability when the scooping frame 13 moves. To clean the residue inside the scooping frame 13, simply pull the pin 15 to disassemble it from the connecting frame 12; this operation is convenient. The bracket 17 supports the filter tank 1, providing a structural foundation for the entire seaweed extract separation process.
