[0002] Sodium alginate is a byproduct of the extraction of iodine and mannitol from brown algae such as kelp or Sargassum. It is a natural polysaccharide that possesses the stability, solubility, viscosity, and safety required for pharmaceutical excipients. Sodium alginate has been widely used in the food industry and pharmaceutical field. The production process of sodium alginate requires the use of extraction tanks.

[0003] During the extraction process, seaweed and alkaline solvent are added to the extraction tank in sequence and stirred. Then, the alginic acid in the seaweed cell wall reacts with the alkaline solvent to generate sodium alginate solution.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments: like Figures 1 to 4 As shown, an extraction tank for sodium alginate production includes an extraction tank body 1, an extraction tank body 1 including a discharge pipe 2, a valve 3 installed on the discharge pipe 2, and a movable pipe 4. The movable tube 4 and the discharge tube 2 have the same diameter. The movable tube 4 is provided with an annular groove (not shown in the figure), and the discharge tube 2 is provided with an annular protrusion 5 that mates with the annular groove. The movable tube 4 is installed on the discharge tube 2 by a locking member 6. The locking member 6 is specifically either a snap fastener or a clamp, without modification (the figure shows a snap fastener connection). The structure of the snap fastener and the clamp is as follows: I. Clamp Connection Core Structure Composed of annular bands, sealing gaskets, and bolts made of stainless steel / carbon steel, it achieves locking by engaging with the pre-fabricated flange at the pipe end through grooves; Sealing gaskets are mostly made of EPDM or silicone; Connection steps Pre-processing: Standard grooves need to be rolled out at the pipe ends, with the depth matching the inner diameter of the clamp; Assembly: Embed the sealing ring into the inner cavity of the clamp, put it on the two pipe ends, and then tighten the bolts alternately to lock it in place; II. Buckle Connection U-shaped buckle: Two-way elastic structure, fastened to round / square tubes with screws; Key points of operation Positioning: Matching slots or holes need to be pre-made at both ends of the tube to ensure that the buckle flange is accurately embedded; Tightening: The U-shaped buckle needs to be inserted into the screw and tightened evenly to avoid stress concentration on one side.

[0016] (In order to improve the sealing of the joint between the movable pipe 4 and the discharge pipe 2 after installation, a sealing ring is further provided in the annular groove, which is not shown in the figure.) Limiting blocks 7 are symmetrically arranged inside the movable tube 4; The filter plate 8 abuts against the limiting block 7 and is attached to the inner wall of the movable tube 4; The slag discharge pipe 9 is inclined downward and connected to the interior of the movable pipe 4. One end of the slag discharge pipe 9 connected to the movable pipe 4 is higher than the filter plate 8 and is equipped with a solenoid valve 91. The fixing rod 10 is fixed inside the discharge pipe 2, and the first connecting roller 11 is vertically rotatably connected inside the fixing rod 10; The second connecting roller 12 is horizontally rotatably connected inside the discharge pipe 2, and the end of the second connecting roller 12 and the upper end of the first connecting roller 11 are driven by a differential gear set 13 (the differential gear set 13 includes a driving gear and a driven gear, the driving gear is fixed on the second connecting roller 12, and the driven gear is fixed on the first connecting roller 11). The drive assembly 14 is mounted on the discharge pipe 2, and the drive assembly 14 is connected to the second connecting roller 12; The scraper assembly 15 is located at the lower end of the first connecting roller 11 and is in contact with the surface of the filter plate 8.

[0017] Specific implementation of this utility model solution, such as Figure 1 As shown, the drive assembly 14 includes a reducer and a servo motor (the reducer and servo motor are not labeled in the figure). The reducer is fixed on the outer wall of the discharge pipe 2. The output end of the reducer is connected to one end of the second connecting roller 12 through a coupling, and the input end of the reducer is connected to the motor shaft of the servo motor through a coupling.

[0018] Specific implementation of this utility model solution, such as Figure 1 As shown, the scraping assembly 15 includes a scraper 151 and bristles 152. The scraper 151 is horizontally fixed in the lower end region of the first connecting roller 11; Several bristles 152 are disposed at the bottom of scraper 151 and in contact with the surface of filter plate 8.

[0019] To reduce the obstruction of the fixing rod 10 to the dispensing of sodium alginate solution, further optimizations to the above-described embodiments are made, such as... Figure 1 As shown, the fixing rod 10 has several leakage holes 101, and the bottom of the fixing rod 10 is provided with several reinforcing ribs (not shown in the figure) that are staggered with the leakage holes 101.

[0020] To prevent seaweed residue from adhering to the differential gear set 13 and affecting the transmission effect, the above embodiment solution is further optimized, such as... Figure 1As shown, the differential gear set 13 is covered by a housing 131 fixed on the fixing rod 10. The housing 131 has a through hole (not shown in the figure) that allows the first connecting roller 11 and the second connecting roller 12 to pass through. Based on this, in order to reduce the probability of seaweed residue remaining on the shell 131, more detailed measures are taken, such as... Figure 1 As shown, a flow guide platform 132 with a high center and low periphery is provided on the upper surface of the housing 131.

[0021] It should be noted that the servo motor and solenoid valve 91 are electrically connected to the controller, which is not shown in the figure. It can be installed on the frame of the extraction tank.

[0022] The working process of this utility model is as follows: After the alginic acid in the seaweed has reacted with the alkaline solvent, valve 3 is opened. At this time, the sodium alginate solution mixed with seaweed residue will flow out from the discharge pipe 2. Initially, the discharge pipe 2 and the movable pipe 4 are accurately connected and installed by locking part 6. Then the material will move to the filter plate 8 (at this time, the solenoid valve 91 is in the closed state). At this time, the sodium alginate solution can pass through the filter plate 8 and flow out from the end of the movable pipe 4 for collection. The seaweed residue is trapped on the filter plate 8. Meanwhile, the servo motor is controlled by the controller to rotate the second connecting roller 12. Then, the scraping assembly 15 can rotate by the differential gear set 13. This will push the seaweed residue to turn over in real time, so that the sodium alginate solution can pass through the filter plate 8 to complete the solid-liquid separation. When the liquid output at the end of the movable tube 4 decreases significantly or stops, the solenoid valve 91 is opened by the controller. The scraping assembly 15 continues to rotate, so that the seaweed residue is discharged from the slag outlet pipe 9. When the filter plate 8 needs to be replaced or cleaned, the valve 3 is closed first, and then the movable tube 4 is removed. After the movable tube 4 is removed, the filter plate 8 can be easily removed for cleaning and the inside of the slag outlet pipe 9 can be rinsed and cleaned. After maintenance, the filter plate 8 can be reinstalled to start a new round of sodium alginate extraction and solid-liquid separation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
