Description

Technical Field

[0001] The invention relates to the technical field of continuous electrical regeneration ion exchange, and more specifically to an ion exchange device for removing heavy metals in oyster peptides. Background Art

[0002] The continuous electro-regenerative ion exchange device, referred to as the EDI system, is a technology for efficiently producing high-purity water. It can effectively remove ionic impurities in water. In the purification process of oyster peptides, the EDI system plays an important role. Since oysters and other shellfish can easily absorb heavy metals such as lead, mercury, cadmium, etc. from the marine environment, these harmful substances will accumulate in their bodies. Therefore, using the EDI system to remove heavy metals in oyster peptides can not only ensure the safety of the product, but also improve the quality and purity of the product.

[0003] In the existing process of purifying oyster peptides through a continuous electrical regeneration ion exchange device, the heavy metal ions in the reagent can be transferred out under the purification effect of the electric field configured in the system and the anion exchange membrane and the cation exchange membrane. However, the ions in the solution may migrate directly from the pure water chamber to the concentration chamber under the action of the electric field, resulting in uneven electric field strength and even short circuit. Therefore, resin is configured as an intermediate medium in the existing treatment method to ensure orderly migration of ions and prevent short circuit. In addition, the configured resin can also be regenerated under the action of the electric field to ensure the stability of continuous electrical regeneration ion exchange.

[0004] However, during the purification of oyster peptides by the EDI system, not all impurities can be removed by electric field regeneration. In particular, inorganic substances such as silicates and iron ions attached to the anion and cation exchange resin groups will undergo irreversible chemical reactions with the resin groups, causing the resin adsorption wall to fail and even cause resin blockage over a long period of time. The resin group is composed of several tiny resin particles, so ordinary flushing cannot effectively act on the inner resin particles, affecting the effect of subsequent ion exchange.

[0020] By setting up two groups of cleaning reagent storage modules at the junction of the anion exchange resin chamber and the cation exchange resin chamber, respectively storing chemical cleaning reagents of different properties, it is possible to configure corresponding chelating agents for organic pollutants adsorbed on the anion resin, and configure corresponding chelating agents for organic pollutants adsorbed on the cation resin, and perform separated synchronous cleaning. The two resin chambers use different cleaning reagents in a separated state, which not only avoids cross-contamination of different reagents during the cleaning process, but also ensures the specificity and effectiveness of the cleaning reagents at the cleaning end.

[0021] By configuring corresponding self-adjusting cleaning mechanisms in the anion exchange resin bin and the cation exchange resin bin, under the linkage and cooperation of the driving mechanism, not only can the self-adjusting cleaning mechanisms on both sides be driven to move to any position in the bin for stirring cleaning as needed, but the injection cavity column in the main injection rod module can also be synchronously driven to rotate, so that the configured angled nozzle cover sprays a rotating water flow outward, forming a vortex on the inner wall of the anion exchange resin bin and the cation exchange resin bin, and enhancing the turbulence of the inner water flow through the impact force and stirring force of the water flow, thereby assisting in improving the cleaning force of the outer cleaning end, and further improving the effect of the exchange resin particles in stripping the outer layer of dirt.

[0022] Through the liquid injection cavity configured on each side of the self-adjusting cleaning mechanism, when the liquid injection cavity moves along the slide rail groove to the liquid outlet circular port position corresponding to the first storage cylinder and the second storage cylinder under the action of the driving force of the driving mechanism, the stored chemical cleaning reagent can be introduced into the stirring end of the self-adjusting cleaning mechanism through the guide hose, so that the cleaning reagent can directly act on the position of the stirring end, which can not only clean the inner layer particles at any height position of the anion exchange resin bin and the cation exchange resin bin, but also ensure that the resin particles at the cleaning position are directly integrated with the reagent, thereby further improving the descaling effect of the device.

[0060] First, open the first outward cover opening 117 on the cover plate 94 located on the anion exchange resin compartment 97 and the cation exchange resin compartment 98, pour the anion exchange resin and the cation exchange resin into the anion exchange resin compartment 97 and the cation exchange resin compartment 98 respectively, then open the second outward cover opening 1110 located on the first storage cylinder 121 and the second storage cylinder 122, and inject the corresponding cleaning reagent therein, the liquid outlet end of the first storage cylinder 121 faces the cation exchange resin compartment 98, so the chemical reagent for cleaning the cation exchange resin particles, such as acidic solution hydrochloric acid, alkaline solution sodium hydroxide, chelating agent, etc., is injected therein, and the liquid outlet end of the second storage cylinder 122 faces the anion exchange resin compartment 97, so the chemical reagent for cleaning the anion exchange resin particles, such as alkaline solution sodium hydroxide, acidic solution nitric acid, etc., is injected therein, and finally the oyster peptide liquid to be treated is injected into the injection cavity column 131 through the injection conduit 113;

[0061] Then, the oyster peptide liquid enters the injection cavity column 131 through the injection conduit 113, and after being pressurized, it is ejected outward from the angled nozzle cover 132 on the outer surface, enters the liquid outlet bin 99 in the inner cylindrical frame 95, and passes through the second arc water leakage mesh cover 96 on the outer side of the liquid outlet bin 99 to enter the anion exchange resin bin 97 and the cation exchange resin bin 98 on both sides. Under the exchange action with the exchange resin inside, the heavy metal ions such as Pb ions, Hg ions, and Cd ions in the solution are first adsorbed by the anion and cation exchange resins, and the heavy metal ions in the solution are removed. After applying a DC electric field with the positive power generator 3 and the negative power generator 4 on both sides, cations such as Pb, Hg, and Cd migrate to the heavy metal reagent transfer chamber 8 through the cation exchange membrane assembly 6, and anions such as Cl migrate to the heavy metal reagent transfer chamber 8 through the anion exchange membrane assembly 7, wherein the oyster peptide solution treated in the resin mixed adsorption chamber 5 flows out from the drainage conduit 10 at the bottom, and the heavy metal ion content in the outflowing liquid is significantly reduced, and the heavy metal ion liquid migrated to the heavy metal reagent transfer chamber 8 on both sides also flows out from the drainage conduit 10 at the bottom;

[0062] Finally, after a round of cleaning is completed, the treated oyster peptide solution is discharged and the filtering steps can be repeated to perform reciprocating work;

[0063] Among them, in order to ensure the ion exchange efficiency of the ion exchange cooperative mechanism 9 at the initial adsorption end, the first servo motor 114 needs to be turned on during the working process. The servo drive action of the first servo motor 114 controls the outer meshing gear ring 112 to rotate around the sealing circular mouth sleeve 111, so that the injection conduit 113 and the injection cavity column 131 at the bottom rotate. During the rotation process, with the action of multiple groups of outwardly inclined angled nozzle sleeves 132 and the bearing base 133 on the base, it can rotate smoothly, form a vortex inside the liquid outlet bin 99, and contact the outer anion exchange resin bin 97 and cation exchange resin bin 98 in the form of a rotating vortex for ion exchange.

[0064] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9As shown, the self-adjusting cleaning mechanism 14 includes a first cleaning frame 141 and a second cleaning frame 142.

A card plate 1413 with a circular hole corresponding to the liquid outlet circular port 126 on the side expansion plate 124 of the second storage cylinder 122 is fixedly installed on the outer surface of the card plate 1413 with a circular hole, and an arc side plate 146 is fixedly installed on the inner surface of the card plate 1413 with a circular hole. A reserved notch 147 aligned with the circular hole of the card plate 1413 with a circular hole is opened on the surface of the arc side plate 146. A second reset spring pull rod 148 is fixedly installed in the reserved notch 147, and an outer top thin rod 149 located at the center of the circular hole on the card plate 1413 with a circular hole is fixedly connected to the reset end of the second reset spring pull rod 148.

[0065] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, a bead sleeve 1410 is movably installed at the outer end position of the outer top thin rod 149, a sealing round cover sleeve 1411 is fixedly sleeved on the outer surface of the outer top thin rod 149, and the extended length of the sealing round cover sleeve 1411 is shorter than the extended length of the outer top thin rod 149, and the upper and lower ends of the inner sides of the arc side plate 146 are fixedly connected with a guide hose 1412 connected with the sealing round cover sleeve 1411, and the upper and lower side surfaces of the first cleaning rack 141 are fixedly installed with an arc hollow frame 143, and the side interiors of the arc hollow frame 143 are all cavity structures, and the other end of the guide hose 1412 away from the sealing round cover sleeve 1411 is respectively connected to the side cavities of the arc hollow frame 143 on the upper and lower sides of the first cleaning rack 141; and the outer ends of the side cavities of the arc hollow frame 143 are fixedly installed with a plurality of spray holes 1421.

[0066] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9As shown, an interlayer groove 1414 is provided on the inner side of the first cleaning frame 141, and track sleeves 1415 are movably installed on the upper and lower sides of the interlayer groove 1414. A second gear plate 1416 is meshed with the track sleeve 1415 at the middle position of the surface of the first cleaning frame 141, and third gear plates 1419 are meshed with the track sleeves 1415 at the two end positions of the surface of the first cleaning frame 141. A plurality of first stirring blades 1418 placed in the middle of the interlayer groove 1414 are fixedly connected to the outer edge of the second gear plate 1416, and a plurality of second stirring blades 1420 placed in the middle of the interlayer groove 1414 are fixedly connected to the outer edge of the third gear plate 1419. A tooth groove 1417 corresponding to the gear rod 116 extending into the anion exchange resin compartment 97 is provided at the center position of the second gear plate 1416.

[0067] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, the second cleaning rack 142 and the first cleaning rack 141 and the arc hollow rack 143, arc limit sleeve 144, injection cavity 145, arc side plate 146, reserved notch 147, second reset spring pull rod 148, outer top thin rod 149, bead sleeve 1410, sealing round cover sleeve 1411, guide hose 1412, card plate with round hole 1413, interlayer groove 1414, track sleeve 1415, second gear plate 1416, tooth groove 1417, first stirring blade 1418, The overall structure of the third gear plate 1419, the second stirring blade 1420, and the spray hole 1421 is the same. The second cleaning rack 142 is slidably clamped in the interior of the cation exchange resin bin 98 through the arc limit sleeve 144. The end of the second cleaning rack 142 provided with the injection cavity 145 is slidably clamped on the end of the side of the first storage cylinder 121 provided with the expansion plate 124. The tooth groove 1417 provided on the second cleaning rack 142 is fitted and corresponds to the gear rod 116 extending into the cation exchange resin bin 98.

[0068] The cleaning process of the configured self-adjusting cleaning mechanism 14 is specifically as follows:

[0069] First, when the device needs to be cleaned, clean water is injected from the liquid injection conduit 113 into the liquid injection cavity column 131, so that the clean water fills the liquid outlet chamber 99, and the clean water enters the anion exchange resin chamber 97 and the cation exchange resin chamber 98 under the action of external supercharging to wash the particles filled therein;

[0070] Then, according to the cleaning requirements, the first servo motor 114 is turned on to control the liquid injection cavity column 131 to cooperate with the inside of the bevel nozzle cover 132 to form a cleaning vortex, thereby increasing the flushing force at the flushing end. While the gear ring 112 drives the liquid injection cavity column 131 to rotate, the first gear plate 115 on the upper surface of the cover plate 94 that meshes with the gear ring 112 will also rotate, and the bottom of each side of the first gear plate 115 is provided with a gear rod 116 extending into the interior of the outer cylindrical frame 91, that is, extending into the anion exchange resin compartment 97 and the cation exchange resin compartment 98 respectively. The gear rod 116 can drive the second gear plate 1416 on each side to rotate under the rotation of the gear rod 116, and the outer side of each second gear plate 1416 is meshed with a track cover 1415. Under the action of the track cover 1415, the third gear plates 1419 on both sides of the track cover 1415 will also rotate, so that the first stirring blade 1418 and the second stirring blade 1420 connected to the outer side rotate, and the particles at the position are stirred, so that the particles accumulated in the inner layer can also flow, and the inclination of the cleaning end is ensured to be thorough;

[0071] Then, according to the cleaning requirements, the second servo motor 118 installed on the upper surface of the cover plate 94 can be opened, and the threaded rod 119 at its output end can be controlled to rotate under the servo drive of the second servo motor 118. Taking the rotation of the threaded rod 119 in the anion exchange resin bin 97 as an example, when the threaded rod 119 rotates, the first cleaning rack 141 engaged therewith will move up and down along the first storage cylinder 121 and the second storage cylinder 122 toward the guide rail sandwich 123 in the anion exchange resin bin 97, so as to move the first cleaning rack 141 to any height position in the anion exchange resin bin 97, and stir and clean the particles at that height. Furthermore, in the process that one end of the liquid injection cavity 145 moves up and down along the guide rail sandwich 123, the first cleaning rack 141 is moved up and down along the guide rail sandwich 123. Under the action of the reset spring pull rod 148, the outer push rod 149 at its reset end always has a tendency to extend outward, that is, to extend outward toward the circular opening of the card plate 1413 with a circular hole. When it extends outward, it will slide into the slide rail groove 125 of the expansion plate 124 of the second storage cylinder 122 on this side, and cooperate with the round ball sleeve 1410 at the outer end to smoothly move up and down along the slide rail groove 125. When the round ball sleeve 1410 moves to the position of the liquid outlet circular opening 126 on the slide rail groove 125, the outer push rod 149 will be further pushed into the liquid outlet circular opening 126 under the outward reset action of the second reset spring pull rod 148, and the sealing head push rod 129 blocking the opening in the liquid outlet circular opening 126 will be squeezed inward until it is pushed into the interior of the second storage cylinder 122.

[0072] Finally, the second storage cylinder 122 pushed into the interior will open the liquid outlet circular port 126, and the outer push rod 149 is a thin rod, so the cleaning reagent will leak out from the position of the opened liquid outlet circular port 126, and because the outer side of the outer push rod 149 is provided with a sealing circular cover sleeve 1411, after the outer push rod 149 is squeezed outward, the sealing circular cover sleeve 1411 shorter than the outer push rod 149 will be sealed against the outer side of the liquid outlet circular port 126, so that the opened liquid outlet circular port 126 is connected to the sealing circular cover sleeve 1411. After the connection, the reagent stored in the second storage cylinder 122 can be guided from the guide hose 1412 outside the sealing circular cover sleeve 1411 to the outer cavity of the arc hollow frame 143 on the upper and lower sides of the first cleaning frame 141, and finally discharged through the spray hole 1421 on the outer cavity of the arc hollow frame 143 to act on the first stirring blade 1418 and the second stirring blade 1420, so that the stirring end can also complete the mixing of the cleaning reagent and the particles during the stirring process, thereby ensuring the cleaning quality at this position;

[0073] Among them, the gear ring 112 configured on its driving mechanism 11 drives the first gear plate 115 during the rotation process, so that the first stirring blade 1418 and the second stirring blade 1420 on the self-adjusting cleaning mechanism 14 on both sides rotate. The process can also be applied to the mixing stage of the resin mixing adsorption bin 5, so that the particles at the adsorption end can flow, thereby improving the effect of ion transfer. Furthermore, the overall structure of the configured second cleaning rack 142 is the same as the overall structure of the first cleaning rack 141, but the liquid injection cavity 145 at the action end is stuck on the expansion plate 124 of the first storage cylinder 121 to export the reagent stored in the first storage cylinder 121 to cooperate with the cleaning of the particles in the cation exchange resin bin 98. The working principle is the same as that of the anion exchange resin bin 97. The reset direction of the configured first reset spring pull rod 127 is outward, so that the configured sealing head top rod 129 can be inserted into the liquid outlet circular port 126 on the same side to seal the opening.

[0074] The method for using an ion exchange device for removing heavy metals from oyster peptides comprises the following steps:

[0075] S1: First, the oyster peptide liquid enters the liquid injection cavity column 131 through the liquid injection conduit 113, and after being pressurized, it is ejected outward from the angled nozzle cover 132 into the liquid outlet chamber 99, and enters the anion exchange resin chamber 97 and the cation exchange resin chamber 98 through the second arc water leakage mesh cover 96;

[0076] S2: Then, the heavy metal ions in the solution are adsorbed by the resin, and then, under the action of the DC electric field provided by the positive power generator 3 and the negative power generator 4, the cations migrate through the cation exchange membrane assembly 6 to the heavy metal reagent transfer chamber 8, and the anions migrate through the anion exchange membrane assembly 7 to the heavy metal reagent transfer chamber 8;

[0077] S3: Then, after the purification reagent is discharged, the first servo motor 114 is started, and the liquid injection cavity column 131 is driven to rotate through the gear ring 112 to form a vortex for cleaning, and the gear ring 112 drives the first gear plate 115 to rotate, so that the first stirring blade 1418 and the second stirring blade 1420 stir the resin particles to ensure that the inner layer particles can also flow;

[0078] S4: Finally, according to the cleaning requirements, the second servo motor 118 is started, and the first cleaning rack 141 and the second cleaning rack 142 are driven by the threaded rod 119 to reach any height position in the resin bin for stirring and cleaning, and enter the circular arc hollow rack 143 through the guide hose 1412, and are sprayed out from the spray hole 1421 to mix with the stirring end to ensure that the cleaning agent is in full contact with the resin particles.
