Description

Technical Field

[0001] This utility model relates to the field of pyridoxal phosphate production technology, and more specifically, it relates to an adsorption and impurity removal device for pyridoxal phosphate production. Background Technology

[0002] Pyridoxal phosphate (PLP), a white crystalline powder, is a derivative of vitamin B6. Pyridoxal phosphate is a coenzyme for transaminases and decarboxylases in amino acid metabolism, and can generate various bioactive substances used to prevent Alzheimer's disease and Parkinson's disease. More importantly, pyridoxal phosphate also has anti-cancer effects. Besides participating in transamination reactions, pyridoxal phosphate also participates in the metabolism of sugars and visceral lipids in the human body and can regulate gene expression. Currently, pyridoxal phosphate production uses resin adsorption to remove impurities. However, existing adsorption and impurity removal devices have low adsorption rates in single-stage adsorption operations and lack suitable multi-stage adsorption and impurity removal mechanisms. Furthermore, the internal filter screen is prone to damage after prolonged use, and internal replacement and maintenance are cumbersome. Additionally, the top cover is difficult to disassemble and reassemble during replacement and maintenance, and a suitable quick-installation locking mechanism is lacking. Utility Model Content

[0027] Please see Figures 1-4 An adsorption and impurity removal device for the production of pyridoxal phosphate includes a base plate 1, with support legs 2 at each of the four corners of the lower end face of the base plate 1, and tanks 3 on both the left and right sides of the upper end face of the base plate 1. Both tanks 3 have detachable cover plates 4 on their upper ends, and both tanks 3 have detachable filter screens 5 inside. Both cover plates 4 have stirring mechanisms. A feeding pipe 6 passes through the upper left end face of the left tank 3, and a discharge pipe 7 passes through the lower right end face of the right tank 3. A pump body 8 is located at the center of the upper end face of the base plate 1, with a suction pipe 9 connected to the left end face of the pump body 8. The suction pipe 9 passes through the upper right end face of the left tank 3, and a feeding pipe 10 is connected to the upper end face of the pump body 8. The feeding pipe 10 passes through the lower left end face of the right tank 3. Both tanks 3 have drain pipes 11 passing through their bottom ends.

[0028] In this embodiment, before the device is used, an appropriate amount of resin is added into the two tanks 3. The pore size of the filter screen 5 is smaller than the size of the resin particles. The pyridoxal phosphate reaction solution to be adsorbed and purified is added into the left tank 3 through the feeding pipe 6. After the left tank 3 is initially adsorbed and purified, the pump 8 is started to transport the product after the initial adsorption and purification in the left tank 3 to the right tank 3. The product is transported through the suction pipe 9 and the feeding pipe 10. The resin in the right tank 3 performs secondary adsorption and purification on the product. The product after adsorption and purification is discharged out through the discharge pipe 7, realizing multi-stage adsorption and purification and improving the adsorption and purification efficiency.

[0029] More specifically, after the adsorption and removal of impurities are completed, the impurities are adsorbed by the resin, and water is added to the two tanks 3 through the water inlet pipe on the cover plate 4 to achieve hydrolysis. The valve on the drain pipe 11 is opened to discharge the impurities outward through the drain pipe 11.

[0030] Please see Figures 1-5As one embodiment of disassembling and assembling the cover plate 4: both cover plates 4 are provided with positioning rods 12 at their bottom ends, and multiple positioning rods 12 are provided in the circumferential direction relative to the cover plate 4. The upper end face of both tanks 3 is provided with positioning holes 13 corresponding to the multiple positioning rods 12. Locking seats 14 are slidably provided on both the front and rear sides of the upper end face of the bottom plate 1. Locking plates 15 are symmetrically provided on the side of the two locking seats 14 near the tank 3. Locking grooves 16 are provided on the front and rear end faces of both cover plates 4 corresponding to the multiple locking plates 15. Adjustment grooves 17 are provided on both the front and rear sides of the upper end face of the bottom plate 1 corresponding to the locking seats 14. Adjustment rods 18 are rotatably provided on the bottom plate 1 corresponding to the two adjustment grooves 17. Adjustment holes 19 are provided on both locking seats 14 corresponding to the adjustment rods 18. The adjustment rods 18 and adjustment holes 19 are threadedly connected.

[0031] Specifically, when installing the cover plate 4, the positioning rod 12 and the positioning hole 13 are used for positioning. After initial positioning, the adjusting rod 18 is rotated, and the adjusting rod 18 and the adjusting hole 19 of the locking seat 14 are threaded together. The internal threads of the two locking seats 14 adjusting holes 19 are set in opposite directions, so as to realize the relative sliding adjustment of the two locking seats 14. The locking seat 14 drives the locking plate 15 to slide, and the locking plate 15 is inserted into the corresponding locking groove 16 to lock the installation.

[0032] Please see Figure 1 , Figure 3 and Figure 4 As an implementation method for internal stirring and maintenance: both stirring mechanisms include stirring shafts 20 and stirring motors 21. The stirring shafts 20 are rotatably mounted on the cover plate 4. The stirring motors 21 are mounted on the upper end of the stirring shafts 20. The stirring shafts 20 are provided with stirring rods 22, and multiple stirring rods 22 are provided. The center positions of the two filter screens 5 are both provided with mounting plates 23. The bottom ends of the two mounting plates 23 are symmetrically provided with guide rods 24. The bottom ends of the two tanks 3 are symmetrically provided with guide sleeves 25 corresponding to the guide rods 24. The upper surfaces of the two mounting plates 23 are provided with rotating seats 26 corresponding to the stirring shafts 20.

[0033] Specifically, the control device has its own control system. When the stirring motor 21 is started, it is fixed to the cover plate 4 by its own L-shaped plate. The stirring motor 21 drives the stirring shaft 20 to rotate. The stirring rod 22 on the stirring shaft 20 stirs the interior and improves the adsorption efficiency. When the filter screen 5 is installed, the bottom guide rod 24 of the mounting plate 23 is installed and positioned corresponding to the bottom guide sleeve 25. After the initial installation, the cover plate 4 is installed as a whole, and the stirring shaft 20 is installed corresponding to the rotating seat 26 to secure the filter screen 5.

[0034] In summary, the overall equipment is in use:

[0035] When the cover plate 4 is in the disassembly / removal state, when the cover plate 4 is disassembled, the adjusting rod 18 is rotated, and the adjusting rod 18 and the adjusting hole 19 are threaded together. The locking seat 14 drives the locking plate 15 to slide and adjust. The locking plate 15 is taken out from the locking groove 16, thus realizing the disassembly operation of the cover plate 4. When the cover plate 4 is installed, the positioning rod 12 and the positioning hole 13 are installed and positioned. When the adjusting rod 18 is rotated in the opposite direction, the locking seat 14 and the locking plate 15 slide and reset as a whole. The locking plate 15 and the locking groove 16 are inserted to realize the installation and locking.

[0036] When the filter screen 5 is in the disassembly / reassembly state, the bottom guide rod 24 of the filter screen 5 mounting plate 23 is installed and positioned corresponding to the guide sleeve 25. After the initial positioning and installation, the cover plate 4 is installed, and the stirring shaft 20 on the cover plate 4 is installed and pressed against the rotating seat 26 above the mounting plate 23, so as to realize the disassembly and replacement of the filter screen 5, which is convenient for replacement and maintenance.

[0037] When the device is in adsorption and impurity removal mode, the valves corresponding to multiple pipelines are opened and closed. The raw liquid of the product to be adsorbed and removed is added into the left tank 3 through the feeding pipe 6. The resin inside the tank adsorbs and removes impurities from the raw liquid. The pump 8 is started, and the product after initial adsorption is sucked out through the suction pipe 9 and fed into the right tank 3 through the feeding pipe 10. The resin inside the right tank 3 performs secondary adsorption and impurity removal on the product, improving the adsorption and impurity removal effect. The product after secondary adsorption and impurity removal is discharged out through the discharge pipe 7. The filter screen 5 blocks the resin. After adsorption and impurity removal, water is added into the tank through the water inlet pipes on the cover plates 4 of the two tanks 3 to hydrolyze the resin. Impurities are discharged downward through the filter screen 5. The valve on the drain pipe 11 is opened to drain the impurities.

[0038] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
