Description

Technical Field

[0001] The utility model relates to the technical field of plant component extraction, in particular to a natural plant effective component extraction device based on membrane separation. Background Art

[0002] The active ingredients of natural plants mainly include flavonoids, alkaloids and polysaccharides. These ingredients are widely distributed in the plant kingdom and have a variety of biological activities and pharmacological effects. Distillation extraction is one of the commonly used methods for extracting the active ingredients of natural plants. That is, the raw materials are distilled through a distillation kettle. The steam generated during the distillation process enters the condenser to condense and form an extract, and then the extract is separated to obtain pure active ingredients. Common separation methods include membrane separation, extraction, crystallization, etc. Membrane separation is a separation technology based on the molecular level, which uses special membranes to selectively permeate certain components in the liquid. In the extraction of active ingredients from natural plants, membrane separation technology can be used to extract active ingredients from complex homogeneous or heterogeneous systems, and purify and refine them by separating and removing impurities.

[0003] At present, when natural plant raw materials are extracted and separated and purified, the extract will directly enter into multiple membrane separators for filtration. As the membrane separators are used continuously, the filtering effect of the microporous filtration membrane in the membrane separators will deteriorate due to impurities, etc. Therefore, the microporous filtration membrane needs to be disassembled for cleaning or replacement. However, when using the existing membrane separators, the outer shell of the membrane separator needs to be disassembled before the microporous filtration membrane, and the outer shell and the end cover are fixed by multiple bolts. This fixing method increases the difficulty of disassembling the membrane separator, affects the disassembly efficiency of the microporous filtration membrane, and further affects the extraction process of natural plant active ingredients. In view of this, we propose a natural plant active ingredient extraction device based on membrane separation. Utility Model Content

[0034] This embodiment provides a technical solution:

[0036] Furthermore, a first connecting ring 421 is coaxially fixed to the bottom end of the housing 42; a second connecting ring 431 is coaxially fixed to the top end of the end cover 43; a sealing cavity 4312 is formed at the top of the second connecting ring 431, and the first connecting ring 421 is inserted into the sealing cavity 4312. By inserting the first connecting ring 421 into the sealing cavity 4312, the connection sealing between the housing 42 and the end cover 43 can be increased, thereby avoiding liquid leakage.

[0037] In this embodiment, a sealing groove 4211 is provided at the bottom of the first connecting ring 421, and a sealing ring 4311 is coaxially fixed in the sealing cavity 4312, and the sealing ring 4311 is plugged into and matched with the sealing groove 4211. The arrangement of the sealing ring 4311 and the sealing groove 4211 can further increase the sealing performance of the connection between the housing 42 and the end cover 43, thereby preventing liquid leakage.

[0038] In this embodiment, the bottom end of the collection box 3 is fixedly connected to the bracket 40 by bolts, and the fixing plate 41 is fixedly connected to the inner wall of the opening of the bracket 40 by bolts. The setting of the bracket 40 plays a role in stably supporting and fixing the collection box 3 and the fixing plate 41.

[0039] In this embodiment, the overall shape of the bracket 40 is U-shaped, and the bracket 40 is made of stainless steel. The bracket 40 made of stainless steel has the advantages of corrosion resistance and high structural strength, which ensures the service life of the bracket 40.

[0040] In this embodiment, a mounting plate 401 is fixed at the bottom end of each bracket 40, and a plurality of mounting holes 4011 are provided on the mounting plate 401. The mounting holes 4011 are provided to facilitate the insertion of bolts, and the bracket 40 can be conveniently installed and fixed by the bolts.

[0041] In this embodiment, the synchronization component includes two symmetrical pulleys 49 coaxially connected to the double-ended screw 46, and a belt 491 is sleeved between the two pulleys 49. This design facilitates driving the two double-ended screws 46 to rotate synchronously in the same direction, thereby facilitating the adjustment of the height of the carrier plate 45.

[0042] In this embodiment, a hand wheel 461 is also installed at the end of the double-ended screw rod 46 located at the front side, and the hand wheel 461 is coaxially keyed with the double-ended screw rod 46. The double-ended screw rod 46 can be conveniently rotated by the hand wheel 461, and this design has the advantage of convenient operation.

[0043] It is understandable that the threads at both ends of the double-ended screw 46 are wound in opposite directions. When the double-ended screw 46 rotates, the connecting blocks 47 on both sides can move synchronously relative to each other, thereby facilitating the adjustment of the height of the supporting plate 45.

[0044] It should be added that the shell 42, the end cover 43 and the microporous filtration membrane 44 in this embodiment are part of the structure of the membrane separator, and the principle thereof is well known to those skilled in the art and will not be described in detail here.

[0045] When the microporous filter membrane 44 needs to be removed, the user first holds the handwheel 461 and turns it. The handwheel 461 drives the double-headed screw 46 to rotate. As the double-headed screw 46 rotates, the pulley 49 rotates. Driven by the belt 491, the double-headed screw 46 on the other side rotates synchronously. As the double-headed screw 46 rotates, the connecting blocks 47 on both sides move inward synchronously. The connecting blocks 47 also drive the support plate 48 to move. The support plate 48 drives the bearing plate 45 to move downward. The bearing plate 45 also drives the end cover 43 to separate from the shell 42. At this time, the microporous filter membrane 44 in the shell 42 is exposed. When the end cover 43 moves to a suitable height, the user stops turning the handwheel 461 and removes the microporous filter membrane 44.

[0046] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
