Description

Technical Field

[0001] The invention relates to the technical field of astaxanthin extraction, in particular to a device for extracting astaxanthin from Haematococcus pluvialis by breaking the wall. Background Art

[0002] Haematococcus pluvialis is a freshwater single-cell green algae. In recent years, Haematococcus pluvialis has been considered one of the best raw materials for producing astaxanthin. Astaxanthin has higher antioxidant activity than carotenoids and vitamin E. Studies have shown that its antioxidant capacity is 10 times that of carotenoids and 550 times that of vitamin E. It is known as a "super antioxidant". Some foreign research institutions have envisioned using astaxanthin as a high-value pharmaceutical raw material, health food raw material, etc.

[0003] The utility model patent with publication number: CN220860654U discloses an astaxanthin purification and concentration tank, which quantitatively delivers the extract to the upper chamber of the tank body through a controller in conjunction with a flow meter, a one-way valve and a peristaltic pump, and cooperates with a lifting mechanism to drive a pressure plate to press the extract out of a plurality of discharge holes on the partition, so that the extract can evenly fall to the lower chamber, and a driving motor drives a mounting frame to drive a plurality of mounting rods to rotate, and the mounting rods drive a stirring member to rotate during the rotation process, and cooperate with the heating process of the heating mechanism to realize heating and stirring work, on this basis, the material on the side wall of the tank body is scraped off by a scraping assembly to reduce the adhesion of the material, and the flipping mechanism drives the stirring frame to rotate to flip the material up and down, so that the extract can evenly exchange heat with the heating mechanism at the bottom of the tank body, that is, it is evenly heated, and the concentrated extract is not prone to stratification.

[0004] However, the above-mentioned methods still have some shortcomings in actual use: 1. The stirring frame is driven to rotate by the turning mechanism to turn the material up and down. If the viscosity of the liquid is relatively high, only the adjacent liquids can be mixed, and large-scale stirring and uniform heating cannot be achieved; 2. When filtering a liquid with a high viscosity, the filtration speed is slow due to the large adhesion between the liquids, and relying on the filter plate, some fine substances will still flow into the liquid, making the filtration impure and affecting the quality of the extraction. Therefore, a wall-breaking extraction device for astaxanthin from Haematococcus pluvialis is proposed to solve the above-mentioned problems. Summary of the invention

[0022] Compared with the existing technology, the advantages of this Haematococcus pluvialis astaxanthin wall breaking extraction equipment are:

[0023] 1. Gear 1 first drives the slide bar to move downward, and then the slide bar only needs to move a little to make the inclined rack bar move toward the rotating gear. The movement of the inclined rack bar is set to drive the rotating gear to rotate 90 degrees. At this time, the stirring plates become vertical. Since gear 1 is continuously rotating, the slide bar will always remain in a state of being squeezed and moved downward by gear 1. Since the side of the slide bar is long enough, the inclined rack bar can stably maintain sliding along the vertical side of the slide bar, thereby ensuring that the stirring plate can maintain a vertical state;

[0024] 2. Then the cam rotates to push the wall-breaking slide bar to move toward the mounting column, and the wall-breaking slide bar pushes the mounting seat and the fixing ring to move, thereby pushing the two stirring plates closer to each other, so that when the telescopic stirring rod is extended and moves downward, the four stirring plates become vertical and continuously move closer and apart, so that the stirring plates have a better mixing, crushing and wall-breaking effect on the Haematococcus pluvialis in the extract, further improving the quality and concentration of the extract;

[0025] 3. The stirring plate becomes horizontal until it moves to the bottom of the extraction box, and then the telescopic stirring rod retracts. Due to the one-way rotation of the ratchet assembly, the four stirring plates will remain horizontal when the telescopic stirring rod retracts, thus forming a complete plane, and the extract in the extraction box is scooped up from the bottom. Only a small part of the extract flows down from the channel between the two silicone scrapers, so that the extract in the entire solid-liquid separation plate can evenly exchange heat with the heating mechanism at the bottom of the extraction box, and evenly heat, and the concentrated extract is not easy to be stratified, with a good concentration effect;

[0026] 4. When separating, the heating mechanisms on both sides need to be pulled out so that the concentrated liquid falls into the separation cloth for solid-liquid separation. When the heating mechanism is pulled out, the inclined push rod can be driven to squeeze the blocking plate, so that the blocking plate is extended in the extraction box body, which can block the stirring plate. At the same time, the push rods 1 and 2 can drive the extraction rod and the separation rod to move, so that the extraction rack is not engaged with the gear 2, and the separation rack is engaged with the gear 2, thereby changing the movement state of the stirring plate. When separating, the telescopic stirring rod extends downward and the gear 2 will not drive the ratchet assembly to rotate, so the four stirring plates form a plane to scrape the extract on the inner wall of the extraction box body;

[0027] In summary, the present invention uses a switching mechanism to enable the stirring and crushing mechanism to move downward in the extraction state so that the stirring plate can be changed to a vertical state, and the stirring plate can be continuously moved closer and separated, so that the stirring plate can have a better mixing, crushing and wall-breaking effect on the Haematococcus pluvialis in the extract; when moving upward, the four stirring plates form a complete plane, and the extract in the extraction box is scooped up from the bottom, so that the extract in the entire solid-liquid separation plate can be evenly exchanged with the heating mechanism at the bottom of the extraction box; in the separation state, the four stirring plates form a plane, and the extract on the inner wall of the extraction box is scraped off, and the linkage blocking mechanism intermittently squeezes the separation cloth to improve the solid-liquid separation efficiency.

[0046] Among them, the upper and lower uniformity mechanisms 404 include a wall-breaking slide bar 32, a cam 26, a ratchet assembly 47 and a gear 2 30. The wall-breaking slide bar 32 is fixedly connected to the mounting seat 36, the wall-breaking slide bar 32 is slidably connected to the mounting column 23, the wall-breaking slide bar 32 is slidably connected to the cam 26, the ratchet assembly 47 is fixedly connected to the cam 26, the gear 2 30 is rotationally connected to the ratchet assembly 47, the cam 26 is rotationally connected to the fixed mounting rod 33 through a set shaft, and two upper and lower uniformity mechanisms 404 are provided, and the two upper and lower uniformity mechanisms 404 are symmetrically distributed.

[0047] In this embodiment, in the extraction state, when the telescopic stirring rod 1 is extended, it drives the mounting column 23 to move downward, and the mounting column 23 drives the wall breaking mechanism 303 and the up and down uniform mechanism 404 to move downward through the fixed mounting rod 33, so that the gear 2 30 engages and rotates with the extraction rack 29, thereby driving the ratchet assembly 47 to rotate, and the rotation of the ratchet assembly 47 drives the cam 26 and the gear 1 27 to rotate synchronously, and then the rotation of the cam 26 will push the wall breaking slide bar 32 to move in the direction of the mounting column 23, and the wall breaking slide bar 32 pushes the mounting seat 36 and the fixing ring 44 to move, thereby pushing the two stirring plates 24 closer to each other, so that when the telescopic stirring rod 1 is extended and moved downward, the four stirring plates 24 become vertical, and continue to approach and separate, so that the stirring plates 24 have a better mixing, crushing and wall breaking effect on the Haematococcus pluvialis in the extract, further promoting the quality and concentration of the extract.

[0055] First, in the extraction state, when the telescopic stirring rod 1 is extended, it drives the mounting column 23 to move downward, and the mounting column 23 drives the wall breaking mechanism 303 and the upper and lower uniform mechanism 404 to move downward through the fixed mounting rod 33, so that the gear 2 30 is meshed and rotated with the extraction rack 29, thereby driving the ratchet assembly 47 to rotate, and the rotation of the ratchet assembly 47 drives the cam 26 and the gear 1 27 to rotate synchronously, so the gear 1 27 first drives the toggle slide bar 34 to move downward, and then the toggle slide bar 34 only needs to move a little to make the inclined rack rod 3 5 moves toward the rotating gear 45, and the inclined rack rod 35 is set to move to drive the rotating gear 45 to rotate 90 degrees. At this time, the stirring plates 24 are all in a vertical state. Since the gear 1 27 is continuously rotating, the toggle slide bar 34 will always remain in a state of being squeezed and moved downward by the gear 1 27. Since the side of the toggle slide bar 34 is long enough, the inclined rack rod 35 can stably maintain sliding along the vertical side of the toggle slide bar 34, thereby ensuring that the stirring plates 24 can maintain a vertical state.

[0056] Subsequently, the rotation of the cam 26 will push the wall-breaking slide bar 32 to move in the direction of the mounting column 23, and the wall-breaking slide bar 32 will push the mounting seat 36 and the fixing ring 44 to move, thereby pushing the two stirring plates 24 closer to each other, so that when the telescopic stirring rod 1 is extended and moves downward, the four stirring plates 24 become vertical and continue to move closer and apart, so that the stirring plates 24 have a better mixing, crushing and wall-breaking effect on the Haematococcus pluvialis in the extract, further improving the quality and concentration of the extract.

[0057] When the telescopic stirring rod 1 is fully extended and the bottom edge of the stirring plate 24 rotates to the bottom of the extraction box 2, the gear 2 30 has been separated from the extraction rack 29. The extraction rack 29 and the separation rack 28 are set to make the gear 2 30 rotate a fixed number of circles, so that the state of the cam 26 of the gear 2 30 is consistent from beginning to end, and the gear 1 27 stops squeezing the toggle slide bar 34, so that the toggle slide bar 34 is reset by the force of the spring 3 31, and then the inclined rack rod 35 is reset, so that the stirring plate 24 becomes horizontal until the stirring plate 24 moves to the extraction box. 2, and then the telescopic stirring rod 1 is retracted. Due to the unidirectional rotation of the ratchet assembly 47, the four stirring plates 24 will remain horizontal when the telescopic stirring rod 1 is retracted, thereby forming a complete plane, and the extract in the extraction box 2 is scooped up from the bottom, and only a small part of the extract flows down from the channel between the silicone scraper strips 25, so that the extract in the entire solid-liquid separation plate 21 can evenly exchange heat with the heating mechanism 3 at the bottom of the extraction box 2, and is evenly heated. The concentrated extract is not prone to stratification, and has a good concentration effect.

[0058] After the extraction is completed, the separation state is entered. During separation, the heating mechanisms 3 on both sides need to be pulled apart so that the concentrated liquid falls into the separation cloth 4 for solid-liquid separation. When the heating mechanism 3 is pulled apart, the inclined push rod 18 can be driven to squeeze the blocking plate 53, so that the blocking plate 53 is extended in the extraction box 2, and the stirring plate 24 can be blocked. At the same time, the push rod 12 and the push rod 2 13 can drive the extraction rod 10 and the separation rod 11 to move, so that the extraction rack 29 is not engaged with the gear 2 30, and the separation rack 28 is engaged with the gear 2 30, thereby changing the movement state of the stirring plate 24. During separation, the telescopic stirring rod 1 extends downward from the gear 2 30 and will not drive the ratchet assembly 47 to rotate, so the four stirring plates 24 form a plane to scrape the extract on the inner wall of the extraction box 2.

[0059] At the same time, when the stirring plate 24 conflicts with the blocking plate 53, the stirring plate 24 can drive the closed sliding bar 15 and the blocking plate 53 to move downward, so that the closed sliding bar 15 drives the rack 14 to move, and the rack 14 drives the extrusion tooth plate 5 to move through the telescopic stirring rod 1 and the extrusion gear 49, and the extrusion tooth plate 5 drives the solid-liquid separation plate 21 to squeeze the separation cloth 4, so that the separation speed of the separation cloth 4 is faster and more efficient. When the telescopic stirring rod 1 moves upward, the two stirring plates 24 become vertical, approach each other and then separate, so that the extract adhering to the stirring plate 24 can be shaken off, avoiding waste of materials.

[0060] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0061] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
