Description

Technical Field

[0001] This utility model belongs to the field of ultrafiltration technology for tanshinone polyphenolic acid salt extract, specifically relating to an ultrafiltration device for tanshinone polyphenolic acid salt extract. Background Technology

[0002] Tanshinone polyphenolic acid salt extract is a liquid rich in polyphenolic compounds extracted from Tanshinone, a traditional Chinese medicine with a wide range of pharmacological activities, especially in the treatment of cardiovascular diseases. Tanshinone polyphenols are one of the main active components of Tanshinone, possessing antioxidant, anti-inflammatory, antithrombotic, and cardiovascular protective effects. Tanshinone polyphenols can scavenge free radicals, reduce oxidative stress-induced cell damage, alleviate inflammatory responses by inhibiting the release of inflammatory mediators, and protect nerve cells from damage through antioxidant and anti-inflammatory effects. After extraction of tanshinone polyphenolic acid salts, ultrafiltration is required to remove large molecular impurities from the extract.

[0003] Chinese utility model patent application number "CN201721888688.7" proposes "a filtration device for plant extraction". The beneficial effect of the utility model is that "the liquid inlet tube in the baffle can perform preliminary filtration of the plant extract. The plant extract is then sprayed out through the nozzle and evenly sprayed onto the ultrafiltration membrane. At this time, after the plant extract is filtered by the ultrafiltration membrane and nanofiltration membrane, it is further treated by adsorption and deodorization by the activated carbon adsorption membrane. The filtration effect is good and the odor can be removed." However, the above device has the following defects: during the ultrafiltration process of the extract, the ultrafiltration membrane is fixedly installed, which may cause blockage of the ultrafiltration membrane during the ultrafiltration process, affecting the filtration effect, wasting the polyphenolic acid salt extract, and reducing the filtration efficiency of the polyphenolic acid salt extract. Therefore, an ultrafiltration device for tanshinone polyphenolic acid salt extract is proposed to solve the above problems. Utility Model Content

[0025] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0026] In this embodiment, see Figure 1-5 An ultrafiltration device for tanshinone polyphenolic acid salt extract includes an ultrafiltration device body 1 and an anti-clogging mechanism 2. The anti-clogging mechanism 2 is located inside the ultrafiltration device body 1. The anti-clogging mechanism 2 includes a threaded rod 201 rotatably mounted on the right side wall of the inner cavity of the ultrafiltration device body 1, with one end penetrating and extending to the outside. A screw block 202 is threadedly connected to the outside of the threaded rod 201. Two discharge hoppers 203 are provided on the outer surface of the screw block 202. This causes the threaded rod 201 to drive the screw block 202 to move left and right, which in turn causes the screw block 202 to drive the discharge hoppers 203 to move left and right, so that the extract can be evenly distributed on the surface of the ultrafiltration membrane 13. A rotating rod 204 with one end for observation and extending to the outside is rotatably mounted. A dual-axis motor 205 is provided on the outside of the ultrafiltration device body 1. The two output shafts of the dual-axis motor 205 are fixedly mounted with connecting shafts 206 through couplings. The outer surfaces of the two connecting shafts 206 are provided with main conical teeth 207. The threaded rod 201 is provided with a first driven conical tooth 208 on the outside. The rotating rod 204 is provided with a second driven conical tooth 209 on the outside. A fixing block 210 is fixedly mounted on the outside of the rotating rod 204. Two support plates 211 are provided on the outside of the fixing block 210. A fixing rod 212 is provided between the opposite sides of the two support plates 211. A disc 213 is provided on the outside of the fixing rod 212.

[0027] It should be noted that when the rotating rod 204 drives the fixed block 210, the two support plates 211, the fixed rod 212 and the disc 213 to rotate, the disc 213 can abut against the ultrafiltration membrane 13, thereby causing the ultrafiltration membrane 13 to move up and down, preventing impurities in the extract from clogging the filter pores of the ultrafiltration membrane 13.

[0028] Technical effect: By setting up a dual-axis motor 205, the dual-axis motor 205 drives two main conical teeth 207 to rotate, which in turn drives the first and second driven conical teeth 208 and 209 to rotate simultaneously. These drive the rotating rod 204 and the threaded rod 201 to rotate simultaneously, causing the threaded rod 201 to move the screw block 202 and the discharge hopper 203 left and right, so that the extract can be evenly distributed on the outer surface of the ultrafiltration membrane 13. At the same time, the rotating rod 204 drives the fixed block 210, the support plate 211, the fixed rod 212 and the disc 213 to rotate, which causes the disc 213 to abut against the ultrafiltration membrane 13, and the ultrafiltration membrane 13 to move up and down, thereby preventing the ultrafiltration membrane 13 from clogging during the filtration process and further improving the filtration efficiency and quality.

[0029] In addition, the movement of the dual-axis motor 205 is a periodic counterclockwise and clockwise movement. The purpose of this is to enable the dual-axis motor 205 to drive the discharge hopper 203 to move back and forth in a circular motion, so that the discharge from the discharge hopper 203 is more uniform.

[0030] Optionally, see Figure 2 The ultrafiltration device body 1 has two baffles 11 inside, and a discharge pipe 12 connected to the inside is provided on the outside of the ultrafiltration device body 1. An ultrafiltration membrane 13 is provided between the left and right side walls of the inner cavity of the ultrafiltration device body 1, and an activated carbon filter plate 14 is provided between the left and right side walls of the inner cavity of the ultrafiltration device body 1. The activated carbon filter plate 14 is provided so that the activated carbon can adsorb harmful gases in the extract, thereby making the filtration effect of the extract better.

[0031] It should be added that the pore size of the activated carbon filter plate 14 is determined according to the content of impurities in the extract, which makes it easier to filter impurities and gases more efficiently.

[0032] Optionally, a limiting block is provided on the outside of the screw block 202, and a limiting groove is provided on the rear side wall of the inner cavity of the ultrafiltration device body 1. The outer surface of the limiting block is slidably connected to the inner wall of the limiting groove, which can limit the screw block 202, so that the screw block 202 can move left and right under the action of the threaded rod 201, and thus drive the discharge hopper 203 to move left and right.

[0033] Optionally, a feeding hole is provided on the outside of the ultrafiltration device body 1. The size of the feeding hole is larger than the size of the discharge hopper 203. The purpose is to send the extract to be ultrafiltered from the feeding hole to the discharge hopper 203, so that the extract is evenly distributed from the discharge hopper 203 to the outer surface of the ultrafiltration membrane 13.

[0034] Optionally, both baffles 11 form an angle with the inner wall of the ultrafiltration device body 1, and both angles are acute angles. This allows the filtered liquid to fall quickly from the baffles 11 into the discharge pipe 12, facilitating the discharge pipe 12 to discharge the liquid to the outside of the ultrafiltration device body 1. This also prevents the filtered liquid from accumulating inside the ultrafiltration device body 1, thus improving the efficiency of liquid discharge.

[0035] Optionally, the rotating rod 204, the fixing block 210, the support plate 211, the fixing rod 212, and the disc 213 are all located below the ultrafiltration membrane 13. Their function is to enable the disc 213 to drive the ultrafiltration membrane 13 to move up and down, so that the ultrafiltration membrane 13 will not be clogged during filtration, thereby further improving the filtration effect.

[0036] Optionally, the two main bevel teeth 207 mesh with the first driven bevel tooth 208 and the second driven bevel tooth 209 respectively, so that the two main bevel teeth 207 simultaneously drive the first driven bevel tooth 208 and the second driven bevel tooth 209 to rotate. This allows the dual-axis motor 205 to simultaneously drive the threaded rod 201 and the rotating rod 204 to rotate, thus eliminating the need for two motors to drive the movement of the two components, saving costs and improving efficiency.

[0037] Optionally, a valve is provided on the outside of the discharge pipe 12, thereby enabling the valve to control the discharge of liquid.

[0038] Optionally, the bottom of the two discharge hoppers 203 is provided with multiple and evenly distributed discharge holes. Both discharge hoppers 203 are located above the ultrafiltration membrane 13. The purpose is to allow the liquid in the discharge hoppers 203 to fall from the discharge holes onto the outer surface of the ultrafiltration membrane 13, so as to facilitate the filtration of the extract.

[0039] It should be noted that the discharge hole on the discharge hopper 203 has a small diameter. The purpose of this is to prevent the liquid from being discharged directly and completely from the discharge hopper 203, but to discharge it slowly from the discharge hopper 203, thereby improving the filtration effect of the extract.

[0040] Optionally, the ultrafiltration membrane 13 is a polyvinylidene fluoride membrane. Polyvinylidene fluoride has excellent chemical resistance, high mechanical strength, good resistance to fouling, and strong hydrophobicity, making it suitable for ultrafiltration of tanshinone polyphenolic acid salt extract.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.

[0042] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
