Description

Technical Field

[0002] Sodium alginate is an indispensable nutrient for the human body. It has an auxiliary therapeutic effect on preventing colon cancer, cardiovascular disease, obesity, and the accumulation of lead and cadmium in the body. It is known as "health and longevity food" in Japan and a wonderful food additive in the United States. As a kind of alginate, it can improve the properties and structure of food with its inherent physical and chemical properties. It is low-heat, non-toxic, easy to expand, and highly flexible. When added to food, its functions are coagulation, adjustment, emulsification, suspension, stabilization, and prevention of food drying.

[0003] The production of sodium alginate belongs to the high-consumption seaweed chemical industry, which consumes a lot of water, electricity and calcium chloride. The traditional process of sodium alginate made from seaweed such as kelp and giant kelp is: soaking - chopping - digestion - dilution - dissolved air - flotation - filtration - calcification - dehydration - drying.

[0004] After the seaweed is digested, the volume of its extract is generally 20 to 40 times the mass of the original algae. Due to the high concentration and viscosity, it is very difficult to directly remove a large amount of residue and insoluble impurities from it. These viscous suspensions are mainly composed of a paste-like sodium alginate liquid and contain a large amount of solid particles such as seaweed epidermis, residue, and mud. The presence of a large amount of residue brings great difficulties to the separation and purification of the subsequent process.

[0005] At present, the existing cyclone separator has a poor effect of separating the liquid from the slurry in the production of sodium alginate, and the residue after separation still contains a large amount of liquid, which is easy to cause waste.

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] The present invention provides Figure 1-6The cyclone separator for producing sodium alginate comprises a separator body 1, an overflow pipe 2 is arranged on the top of the separator body 1, an underflow pipe 3 is arranged on the bottom of the separator body 1, a filter cartridge 4 is connected to the bottom of the underflow pipe 3, a mesh cylinder 5 is nested inside the filter cartridge 4, the left and right ends of the mesh cylinder 5 are fixedly sealed to the left and right side walls of the inner cavity of the filter cartridge 4, a water storage cavity 6 is formed between the outer wall of the mesh cylinder 5 and the inner cavity wall of the filter cartridge 4, an input channel 7 is arranged on the left end of the top of the filter cartridge 4, the input channel 7 extends into the mesh cylinder 5, and the inside of the mesh cylinder 5 An auger 8 is movably nested, a motor 9 is installed at the left end of the filter residue cylinder 4, and the output end of the motor 9 is connected to the auger 8. A filter box 10 is arranged on the left side of the upper end of the separator body 1, and the filter box 10 includes an upper box body 11 and a slag collecting bucket 12. A feed port 13 is arranged on the left side of the upper box body 11, and a discharge port 14 is arranged on the right side of the upper box body 11. The port of the discharge port 14 is connected with a feed pipe 15, and the feed pipe 15 is connected to the left side of the upper end of the separator body 1. A filter cavity 16 is arranged inside the upper box body 11, and a filter screen 17 is installed inside the filter cavity 16.

[0024] The slag collecting bucket 12 is located below the upper box body 11, and the slag collecting bucket 12 and the upper box body 11 are connected by bolts. A sealing strip is provided at the connection between the slag collecting bucket 12 and the upper box body 11, and a discharge pipe 19 is provided at the bottom of the slag collecting bucket 12. A discharge valve 20 is installed on the discharge pipe 19. When the discharge valve 20 is opened, the residue collected in the slag collecting bucket 12 can be discharged through the discharge pipe 19.

[0025] The input channel 7 is connected to the bottom end of the underflow pipe 3 via a flange and bolts, and the underflow pipe 3 is connected to the bottom end of the separator body 1 via a flange and bolts, so that the installation between the input channel 7 and the underflow pipe 3 is simple and reliable, and the installation between the underflow pipe 3 and the separator body 1 is simple and reliable, and easy to disassemble.

[0026] The blade spacing of the auger 8 decreases from right to left, which can gradually increase the squeezing force on the transported residue, so that the liquid in the residue is squeezed out.

[0027] A slag discharge pipe 21 is provided at the lower left part of the filter residue cylinder 4. The slag discharge pipe 21 extends into the mesh cylinder 5. A slag discharge valve 23 is installed on the slag discharge pipe 21. When the slag discharge valve 23 is opened, the residue in the mesh cylinder 5 moves to the left end and is discharged through the slag discharge pipe 21.

[0028] A drain pipe 24 is installed at the lower right part of the filter residue cylinder 4. The inner cavity of the drain pipe 24 is connected with the inner cavity of the water storage chamber 6. The liquid in the water storage chamber 6 can be discharged through the drain pipe 24, making it convenient to discharge the liquid in the water storage chamber 6.

[0029] The separator body 1 includes an upper cylinder 25 and a conical cylinder 26, which are sealed and connected by bolts. The overflow pipe 2 passes through the upper cylinder 25 and extends into the upper cylinder 25. The feed pipe 15 and the upper cylinder 25 are integrally formed. The inner cavity of the feed pipe 15 is connected with the inner cavity of the separator body 1, which is convenient for disassembly and cleaning of the separator body 1 and maintenance of the separator body 1.

[0030] The specific implementation method is as follows: when the feed liquid enters the filter chamber 16 in the filter box 10 through the feed inlet 13 and then enters the discharge port 14 through the filter screen 17, the filter screen 17 intercepts the impurities in the feed liquid, and the intercepted residue falls into the slag collecting bucket 12 for storage. The feed liquid can be pre-filtered by the filter screen 17 to filter out a large amount of impurities in the feed liquid, and then enters the separator body 1 for separation treatment, which effectively improves the effect of liquid-slag separation. The filtered feed liquid enters the separator body 1 through the feed pipe 15 to form a vortex, and the impurities in the feed liquid enter the filter residue cylinder 4 through the underflow pipe 3, and the clear liquid enters the overflow pipe 2 and is discharged through the overflow pipe 2. Impurities enter the mesh cylinder 5 through the input channel 7, and the motor 9 drives the auger 8 to rotate, so that the impurities are transported from right to left. Since the blade spacing of the auger 8 decreases from right to left, during the transportation process, the blades of the auger 8 can gradually increase the extrusion force on the transported residue, so that the liquid in the residue is squeezed out, and the liquid falls into the water storage chamber 6 through the mesh holes of the mesh cylinder 5, and then is discharged from the drain pipe 24. The squeezed residue is discharged through the slag discharge pipe 21. This embodiment specifically solves the problem that the cyclone separator in the prior art has a poor effect on liquid-slag separation of the slurry produced by sodium alginate, and the separated residue still contains a large amount of liquid, which is easy to cause waste.

[0031] like Figure 4-7 As shown, the filter cavity 16 is set to be rectangular, and a reinforcing frame 18 is installed inside the filter cavity 16. The upper side of the reinforcing frame 18 is connected to the top left end of the filter cavity 16, and the lower side of the reinforcing frame 18 is connected to the lower end of the right side wall of the filter cavity 16. The front and rear sides of the reinforcing frame 18 are connected to the front and rear side walls of the filter cavity 16. The filter net 17 is installed on the left side of the reinforcing frame 18. The reinforcing frame 18 improves the impact resistance of the filter net 17, making the filter net 17 not easily damaged.

[0032] A reinforcing rod 22 is fixed to the outside of the mesh cylinder 5. There are multiple reinforcing rods 22, which are distributed in a circular array on the outside of the mesh cylinder 5. The front and rear ends of the reinforcing rod 22 are fixedly connected to the front and rear inner walls of the filter residue cylinder 4. The reinforcing rod 22 can improve the structural strength of the mesh cylinder 5, making it less likely to be damaged.

[0033] The bottom height of the right end of the water storage chamber 6 is higher than the bottom height of the left end, so that the liquid in the water storage chamber 6 can be concentrated to the left end of the water storage chamber 6, so that the liquid in the water storage chamber 6 can be completely discharged through the drain pipe 24.

[0034] The specific implementation method is as follows: the feed liquid continuously impacts the filter screen 17, and the filter screen 17 is tilted so that the filter screen 17 is not easily blocked, and a reinforcing frame 18 is provided. The reinforcing frame 18 improves the impact resistance of the filter screen 17, so that the filter screen 17 is not easily damaged, and the service life of the filter screen 17 is increased. A plurality of reinforcing rods 22 are fixed to the outside of the net tube 5, and the plurality of reinforcing rods 22 are distributed in a ring array on the outside of the net tube 5. The structural strength of the net tube 5 can be improved by the reinforcing rods 22, so that the net tube 5 is not easily damaged, and the service life of the net tube 5 is increased. The bottom height of the right end of the water storage chamber 6 is higher than the bottom height of the left end, so that the liquid in the water storage chamber 6 can be concentrated to the left end of the water storage chamber 6, so that the liquid in the water storage chamber 6 can be completely discharged through the drain pipe 24. This implementation method specifically solves the problem that the liquid in the water storage chamber cannot be completely discharged in the prior art.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
