Description

Technical Field

[0001] This utility model relates to the technical field of extraction equipment for polysaccharides from marine invertebrates, specifically to an extraction device for polysaccharides from marine invertebrates. Background Technology

[0002] Marine invertebrates are the most numerous group in terms of both species and phylum, constituting the vast majority of marine animals. Invertebrates are animals without a vertebral column on their backs; they represent the primitive form of animals. They account for 95% of all animal species, are distributed worldwide, and contain a variety of bioactive substances. Among these, polysaccharides have attracted considerable attention due to their unique structure and function. A polysaccharide extraction device is used to extract these polysaccharide components.

[0003] The prior art provides a separation device for extracting sea cucumber polysaccharides (publication number CN212633050U), which includes a box body. A mixing chamber is fixedly connected to the top of the inner cavity of the box body. A rotating column is rotatably connected to the top of the inner cavity of the mixing chamber. A fixing block is fixedly connected to the bottom end of the rotating column. Rotating rods are rotatably connected to both sides of the outer surface of the fixing block. Centrifuge racks are fixedly connected to the bottom ends of the two rotating rods. A telescopic rod is fixedly connected to the bottom of the fixing block. A first rotating component is fixedly connected to the bottom end of the telescopic rod. Rotating frames are rotatably connected to both sides of the inner surface of the first rotating component. This invention allows for adjustment of the angle of the centrifuge rack through the cooperation between the rotating column, rotating rods, fixing block, telescopic rod, and rotating frame, thereby adjusting the degree of centrifugation. This increases the degree of centrifugation, avoids excessive polysaccharide components being incompletely extracted, and is relatively simple to operate.

[0004] Based on the above patent search, in actual use, the polysaccharide extraction equipment lacks effective heat preservation function, making it difficult to maintain a stable temperature environment during operation. This may lead to instability in the polysaccharide molecular structure, affecting the purity and activity of the extracted product. At the same time, the extraction efficiency of polysaccharides is significantly reduced under low temperature conditions, prolonging the extraction time and increasing energy consumption. Therefore, we need to propose an extraction device for polysaccharides from marine invertebrates. Utility Model Content

By setting up a stirring component and a water bath insulation component, the stirring component stirs the raw materials in the centrifuge tube, and under the action of centrifugal force, the marine invertebrate tissues can be efficiently centrifuged and separated.

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] An extraction device for polysaccharides from marine invertebrates includes an extraction tank 1, a sealing cap 2 at the top of the extraction tank 1, a feed pipe 3 connected to the top of the sealing cap 2, a discharge pipe 4 connected to the bottom of the extraction tank 1, an annular block 5 at the bottom of the sealing cap 2, a centrifuge cylinder 6 inside the annular block 5, and multiple sets of centrifuge holes 7 on the outside of the centrifuge cylinder 6.

[0025] The bottom of the sealing cap 2 is equipped with a stirring assembly 8 for centrifugal extraction of polysaccharides from marine invertebrates, and the outside of the extraction tank 1 is equipped with a water bath insulation assembly 9 to maintain the internal temperature of the extraction tank 1.

[0026] The water bath insulation component 9 includes a heating water tank 91 fixedly installed on the outside of the extraction tank 1. An insulation cavity 92 is opened inside the extraction tank 1. A water pump 93 is installed at the bottom of the heating water tank 91. The water inlet of the water pump 93 is connected to the bottom of the heating water tank 91 through an inlet pipe. The water outlet of the water pump 93 is connected to a delivery pipe 94. The end of the delivery pipe 94 away from the water pump 93 is connected to a heating coil 95. The end of the heating coil 95 away from the delivery pipe 94 is connected to a return pipe 96. Through the setting of the water bath insulation component 9, and the circulation system design of the heating water tank 91, water pump 93, heating coil 95 and return pipe 96, a constant temperature environment can be provided for the extraction tank 1, ensuring that the polysaccharide extraction process is carried out at a suitable temperature, thereby improving the extraction efficiency and product quality.

[0027] The bottom end of the return pipe 96 is connected to the top of the heating water tank 91. The heating coil 95 is set in the heat-insulating cavity 92. The connection between the return pipe 96 and the heating water tank 91 realizes the recycling of hot water and reduces energy consumption. At the same time, the heating coil 95 is set in the heat-insulating cavity 92, which further improves the heat utilization efficiency and ensures that the temperature distribution inside the extraction tank 1 is uniform, avoiding local overheating or overcooling.

[0028] The stirring assembly 8 includes a motor 81 fixedly installed on the top of the sealing cover 2. The output end of the motor 81 is fixedly connected to a rotating rod 82 via a coupling. The rotating rod 82 is rotatably installed inside the sealing cover 2. Two sets of stirring rods 83 are symmetrically installed on the outer side of the rotating rod 82. Through the arrangement of the stirring assembly 8, the motor 81 drives the rotating rod 82 and the stirring rods 83. The two sets of symmetrically arranged stirring rods 83 can fully stir the raw materials, accelerate the dissolution and release of polysaccharides, and improve the extraction efficiency. The stirring assembly 8 is located at the bottom of the sealing cover 2. After extraction, the sealing cover 2, the stirring assembly 8, and the centrifuge cylinder 6 are removed together. The centrifuge cylinder 6 is detachable, which facilitates the cleaning of the residue inside.

[0029] A spiral blade 10 is fixedly installed on the outer side of the rotating rod 82, and a fixed cylinder 11 is fixedly installed on the inner bottom of the centrifuge cylinder 6. Multiple sets of through grooves 12 are opened at the bottom end of the fixed cylinder 11. Through the arrangement of the spiral blade 10, the fixed cylinder 11 and the through grooves 12, the spiral blade 10 rotates in the fixed cylinder 11, pushing the material at the bottom of the centrifuge cylinder 6 through the through grooves 12 into the fixed cylinder 11. The spiral blade 10 flips it upward, thereby achieving full mixing of the material.

[0030] Multiple sets of through channels 12 are arranged in a ring array, and the spiral blades 10 are located inside the fixed cylinder 11. Through the arrangement of the through channels 12 and the spiral blades 10, the through channels 12 are arranged in a ring array to ensure that the material is evenly distributed in the centrifuge cylinder 6, avoiding local accumulation or emptying, and improving separation efficiency. The spiral blades 10 are located inside the fixed cylinder 11, which can efficiently push the material through the through channels 12, and at the same time fully stir the material to improve the extraction effect.

[0031] Cleaning brushes 13 are installed on the outer sides of the two sets of stirring rods 83 respectively. The side of the two sets of cleaning brushes 13 away from the stirring rods 83 is in contact with the inner wall of the centrifuge cylinder 6. The cleaning brushes 13 can automatically remove the residue attached to the inner wall of the centrifuge cylinder 6, prevent the residue from clogging the centrifuge hole 7, and also assist the stirring rods 83 in stirring the material, thereby improving the stirring effect.

[0032] Working Principle: In use, marine invertebrate raw materials and extraction solvent are added to the extraction tank 1 through the feed pipe 3. The sealing cap 2 is tightly connected to the top of the extraction tank 1 to ensure the extraction process takes place in a sealed environment, preventing external contamination. Then, the stirring assembly 8 is activated, and the motor 81 drives the rotating rod 82 to rotate, which in turn drives the stirring rod 83 and the spiral blades 10 to thoroughly stir the raw materials, accelerating the dissolution and release of polysaccharides. Simultaneously, the spiral blades 10 rotate within the fixed cylinder 11, pushing the material at the bottom of the centrifuge cylinder 6 through the channel 12 into the fixed cylinder 11. The spiral blades 10 then tumble the material upwards, achieving thorough stirring. During the centrifugal process, the polysaccharide solution is filtered out through the centrifuge hole 7 under centrifugal gravity, while the residue remains in the centrifuge cylinder 6. During the extraction of polysaccharide components, the water bath insulation component 9 heats the water through the heating water tank 91. The water pump 93 delivers the hot water to the heating coil 95 through the delivery pipe 94. The heating coil 95 circulates within the insulation cavity 92, providing a constant temperature environment for the extraction tank 1 and ensuring that the extraction process is carried out at a suitable temperature. The return pipe 96 sends the cooled water back to the heating water tank 91, forming a circulation system to maintain a stable temperature. After the extraction is completed, the polysaccharide solution is discharged through the discharge pipe 4, thus achieving efficient extraction of polysaccharide components.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
