Description

Technical Field

[0001] The utility model relates to the technical field of biological extraction, in particular to a leech active component extractor. Background Art

[0002] In the production process of leech mask, a leech active ingredient extractor is needed, which mainly uses leeches for extraction; leeches are organisms that contain a variety of active ingredients with medicinal value, such as antithrombin, fibrinolytic enzyme, hyaluronidase, etc. These ingredients have broad application prospects in the fields of medicine and health care products. Therefore, extracting these active ingredients is of great significance for the rational utilization of leech resources and the development of the pharmaceutical industry; At present, there are many ways to extract leech active ingredients, such as ultrasonic extraction, microwave extraction, centrifugal extraction, etc.; Among them, centrifugal extraction is one of the most widely used methods; In the centrifugal extraction method, it is necessary to first take leech coarse powder and add purified water, stir and immerse, take the supernatant after centrifugation, and then ultrafilter the supernatant, collect the filtrate, and then concentrate the supernatant to obtain the extract of leech active ingredients; In the process of centrifugal extraction, centrifugal equipment is needed to obtain the supernatant.

[0003] The utility model patent with authorization announcement number CN214680156U discloses a centrifugal extraction device, which includes a body component, a centrifugal component and several extraction components. The centrifugal component is installed on the body component, and each extraction component is evenly installed at the centrifugal component. The extraction component includes a limiting sleeve and an extraction module, and the extraction module is installed in the limiting sleeve. The extraction module includes a second centrifuge tube, a sealing ring, a first centrifuge tube, a sealing plug, a guide hopper, a baffle and a blocking net. One end of the first centrifuge tube is inserted into the second centrifuge tube, a sealing ring is provided between the first centrifuge tube and the second centrifuge tube, an end of the first centrifuge tube away from the second centrifuge tube is plugged with a sealing plug, an end of the first centrifuge tube close to the second centrifuge tube is provided with a baffle, a blocking net is provided in the middle of the baffle, and a guide hopper is provided in the end of the first centrifuge tube close to the second centrifuge tube, the end of the guide hopper is fixedly connected to the baffle, and the opening end of the guide hopper is located at the blocking net. The centrifugal assembly can be used to centrifugally separate and extract the biological fluid in the extraction assembly installed in the centrifugal assembly. The extraction assembly can separate the stratified liquids therein into layers, effectively preventing the separated liquids from remixing, and improving the extraction effect of the biological fluid.

[0004] Although the centrifugal extraction device can improve the extraction effect, its operation process still has obvious shortcomings in practical applications. Especially when large-scale leech active ingredient extraction is carried out, the device requires manual placement of raw materials into multiple test tubes one by one, which is extremely cumbersome and consumes a lot of human resources. In view of this, we propose a leech active ingredient extraction instrument. Utility Model Content

A plate body 24 is connected to the connecting tube 21 by a coaxial key. A plurality of shifting grooves 242 are provided on the outer wall of the plate body 24. A damping groove 241 is provided between two adjacent shifting grooves 242. A turntable 25 is rotatably mounted on one side of the plate body 24. A damping block 252 is coaxially fixed at the bottom center of the turntable 25. The outer wall of the damping block 252 is fitted with the outer wall of the damping groove 241. A shifting rod 251 is fixed at the bottom edge of the turntable 25, which can slide along the shifting groove 242 and push the plate body 24 to rotate. A third motor 26 for driving the turntable 25 to rotate is installed in the opening of the fixed frame 20.

[0030] Furthermore, connecting rods 12 are fixedly connected to the top ends of the base 10 by bolts, and a bearing plate 14 is fixed between the top ends of two adjacent connecting rods 12. Two electric cylinders 15 for driving the movable plate 13 to rise and fall are installed on the top of the bearing plate 14. The electric cylinders 15 facilitate the lifting and lowering of the movable plate 13, thereby facilitating the adjustment of the height of the feed head 23 for material discharge.

[0031] In this embodiment, the discharge pipe 162 is fixedly connected to the housing 16 through a flange, and a solenoid valve 163 is installed on the discharge pipe 162. The solenoid valve 163 is used to conveniently control the discharge of materials, thereby meeting the use requirements.

[0035] It should be added that the outer wall of the damping block 252 in this embodiment is provided with a notch. When the lever 251 slides in the slot 242 , the damping block 252 does not contact the plate body 24 due to the notch, thereby facilitating smooth rotation of the plate body 24 .

[0036] In addition, the centrifuge 11 in this embodiment is an existing conventional technology, and its principle is well known to those skilled in the art, and will not be described in detail here.

[0037] It is worth noting that the first motor 113, the second motor 17 and the third motor 26 involved in this embodiment are existing conventional technologies and will not be described in detail here.

[0038] Before use, the user first puts the leech powder and purified water into the housing 16 through the liquid filling port 161, and tightens the sealing cover. Then, the user turns on the power of the second motor 17, and the output shaft of the second motor 17 drives the stirring shaft 171 and the stirring blade 172 to rotate, so that the leech powder and purified water are mixed in the housing 16; when the stirring is completed, the power of the second motor 17 is turned off; then the user puts the test tube into the corresponding fixed groove 1121;

[0039] When in use, the user first turns on the power of the third motor 26, and the third motor 26 starts to work. The output shaft of the third motor 26 rotates one circle and drives the turntable 25 to rotate one circle. At this time, the lever 251 slides along the lever groove 242 and pushes the plate body 24 to rotate. When the lever 251 is separated from the lever groove 242, the plate body 24 stops rotating. At this time, the plate body 24 rotates 60° and drives the connecting pipe 21, the connecting bin 22 and the feeding head 23 to rotate 60°. The feeding head 23 rotates to the top of the test tube at the same time; then the user turns on the power of the solenoid valve 163, and the material body flows through the discharge pipe 162, the connecting pipe 21, the connecting bin 22 and the feeding head 23. The material is transported into the test tube. When the material in the test tube reaches a predetermined height, the user stops the operation of the solenoid valve 163 and repeats the above steps to sequentially transport the material into multiple test tubes. Next, the user seals the opening of the test tube by means of a plug and covers the opening of the casing 111 with the cover. At this time, the user turns on the power of the first motor 113. The output shaft of the first motor 113 rotates to drive the rotating body 112 to rotate. The rotating body 112 drives multiple test tubes to rotate. Under the action of centrifugal force, a supernatant is formed in the test tube. Finally, the user stops the first motor 113 and takes out the supernatant in the test tube to obtain the supernatant containing the active ingredient of leeches.

[0040] 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.
