Description

Technical Field

[0001] This utility model relates to the field of bioengineering technology, and in particular to a plant extraction and screening device. Background Technology

[0002] Plant extraction in the field of bioengineering refers to the process of separating and enriching target components from plant tissues (roots, stems, leaves, flowers, fruits, etc.) using technologies such as biochemistry and separation engineering. By screening suitable extraction methods (such as enzymatic hydrolysis, ultrasound-assisted extraction, supercritical extraction, etc.) and combining them with purification technologies such as filtration, chromatography, and membrane separation, the efficient acquisition of bioactive substances (such as polysaccharides, flavonoids, alkaloids, natural pigments, etc.) from plants can be achieved. Its core lies in preserving the activity of components and optimizing extraction efficiency. It is widely used in the fields of natural drug development, functional food research and development, and biological agent production, providing key raw material support for downstream applications of bioengineering.

[0003] When extracting from plants, the plant tissues need to be pretreated first. Pretreatment can break down the structural barriers of the plant tissues and remove interfering substances. However, existing equipment mostly relies on manual crushing and screening of plant tissues, which is not only costly but also greatly affects work efficiency.

[0004] Therefore, we propose a plant extraction screening device to solve the above problems. Utility Model Content

Vibration ports are opened on both sides of the pretreatment shell. Vibration supports are fixedly installed on the inner side of each vibration port. A vibration mechanism is provided on the inner side of each vibration support.

[0010] Specifically, two guide plates are fixedly installed on the inner side of the crushing hopper, and a screening hopper is fixedly installed on the inner side of the pretreatment shell.

[0011] Specifically, the vibration mechanism includes two guide rods, four springs, a slider, an eccentric block, and a vibration servo motor. Two guide rods are fixedly installed on the bottom inner wall of the vibration bracket, and the same slider is slidably mounted on each of the two guide rods. The slider is slidably mounted on the inner side of the vibration bracket. Two springs are mounted on each of the two guide rods, and one end of each of the four springs is fixedly connected to the same slider. The other ends of the four springs are respectively fixedly connected to the corresponding inner wall of the vibration bracket. An eccentric block is rotatably mounted on one side of the slider. A motor slot is formed on the inner side of the slider, and a vibration servo motor is fixedly mounted on the inner side of the motor slot. The output shaft of the vibration servo motor is fixedly connected to the eccentric block, allowing the vibration servo motor to drive the eccentric block to rotate.

[0012] Specifically, the same baffle is fixedly installed on the side of the two sliders that are close to each other, and an inclined screening screen is fixedly installed at the bottom of the baffle to facilitate the vibration of the inclined screening screen.

[0013] Specifically, a granule hopper and a fragment hopper are fixedly installed on the inner side of the pretreatment shell. The granule hopper is located directly below the inclined screening screen. A sliding opening is provided on one side of the pretreatment shell. A granule bin and a fragment bin are slidably installed on the bottom inner wall of the sliding opening. The granule bin is located directly below the discharge end of the granule hopper, and the fragment bin is located directly below the discharge end of the fragment hopper. This allows for the separate storage of plant tissues with and without the required particle size.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: through the set drive mechanism and screening mechanism, the plant tissue to be extracted can be pretreated conveniently and quickly. Plant cells are protected by cell walls and cell membranes. Breaking them can destroy the cell structure, so as to fully release the target components and improve the extraction efficiency.

[0024] In this embodiment, a crushing servo motor 8 is fixedly installed on the bottom inner wall of the drive chamber. The output shaft of the crushing servo motor 8 is fixedly connected to the double row of drive wheels 9. The fast wheel 11 and the slow wheel 13 are respectively fixedly sleeved on the corresponding drive shaft 6.

[0025] In this embodiment, two guide plates 10 are fixedly installed on the inner side of the crushing hopper 2, and a screening hopper 15 is fixedly installed on the inner side of the pretreatment shell 1.

[0026] In this embodiment, the vibration mechanism includes two guide rods 19, four springs 20, a slider 21, an eccentric block 22, and a vibration servo motor 23. Two guide rods 19 are fixedly installed on the bottom inner wall of the vibration bracket 18. The same slider 21 is slidably sleeved on both guide rods 19. The slider 21 is slidably installed on the inner side of the vibration bracket 18. Two springs 20 are sleeved on both guide rods 19. One end of each of the four springs 20 is fixedly connected to the same slider 21, and the other end of each of the four springs 20 is fixedly connected to the inner wall of the corresponding side of the vibration bracket 18. An eccentric block 22 is rotatably installed on one side of the slider 21. A motor slot is opened on the inner side of the slider 21.

[0027] In this embodiment, the same baffle 17 is fixedly installed on the side of the two sliders 21 that are close to each other. An inclined screen 16 is fixedly installed at the bottom of the baffle 17 to facilitate the vibration of the inclined screen 16.

[0028] In this embodiment, a granule hopper 24 and a fragment hopper 25 are fixedly installed on the inner side of the pretreatment shell 1. The granule hopper 24 is located directly below the inclined screen 16. A sliding opening is provided on one side of the pretreatment shell 1.

This allows for the separate storage of plant tissues with qualified particle size and those with unqualified particle size.

[0029] Working Principle: During the extraction and screening of plant tissues, pretreatment is required. The plant tissues are poured into the crushing hopper 2, and then the crushing servo motor 8 is started. The servo motor 8 drives the double-row drive wheels 9 to rotate. The rotation of the double-row drive wheels 9 drives the fast wheel 11 and the slow wheel 13 via the fast belt 12 and slow belt 14 respectively. Since the diameter of the fast wheel 11 is smaller than that of the slow wheel 13, the fast wheel 11 rotates faster than the slow wheel 13. The fast wheel 11 and the slow wheel 13 drive the corresponding crushing rollers 3 via the corresponding drive shafts 6. The speed difference between the two crushing rollers 3 provides better tearing force, resulting in more thorough crushing. Simultaneously, multiple cutter wheels 4 and multiple crushing wheels 5 are fixedly fitted onto the surface of each crushing roller 3, which can adapt to plant tissues of different shapes and materials, enhancing the equipment's applicability. The crushed plant tissues fall into the screening hopper 15 due to inertia, and then onto the inclined screening screen 16. At this point, the two... Two vibration servo motors 23 are activated to drive the corresponding eccentric blocks 22 to rotate. The rotation of the two eccentric blocks 22 generates inertia. Since the two sliders 21 are slidably sleeved on the corresponding two guide rods 19, the rotation of the two eccentric blocks 22 generates inertia, which drives the corresponding sliders 21 to move up and down. Two springs 20 are fixedly installed on the upper and lower sides of the two sliders 21. Therefore, the two sliders 21 can only move up and down with a small amplitude but a high frequency. The movement of the two sliders 21 drives the same baffle 17 to move, which in turn drives the inclined screening screen 16 to vibrate, screening the plant tissue falling on it. The plant tissue is screened according to the particle size of the crushed plant tissue. Qualified plant tissue passes through the inclined screening screen 16 and enters the particle hopper 24, and then falls into the particle chamber 26. The oversized plant tissue slides down the inclined screening screen 16 with inertia and enters the fragment hopper 25, and then falls into the fragment chamber 27, completing the pretreatment of the plant tissue, which is convenient for subsequent extraction and purification.

[0030] The technological advancements of this invention compared to existing technologies are: it allows for convenient and quick pretreatment of plant tissues that are about to undergo extraction. Plant cells are protected by cell walls and cell membranes; breaking them can disrupt the cell structure, allowing target components such as polysaccharides and alkaloids to be fully released, thus improving extraction efficiency. Subsequently, the plant particles are sieved, and the particle size after breaking is controlled, facilitating subsequent extraction and purification of the plant tissues.
