Description

Technical Field

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

[0002] Wild mushroom polysaccharides are natural products with important biological activities and various potential health benefits, including enhancing immunity, anti-tumor activity, and antioxidant properties. The extraction efficiency and purity of polysaccharides are crucial for their subsequent applications. Traditional polysaccharide extraction methods mainly include water extraction, acid-base extraction, and enzymatic hydrolysis. Among these, water extraction is widely used in industrial production due to its simple equipment, ease of operation, and low cost.

[0003] A search revealed Chinese patent application CN201820717924.7, which discloses a water treatment device for extracting polysaccharide protein from *Mushroom oyster mushroom*. The device includes, from top to bottom, a purified water tank, a first measuring tube, a measuring chamber, a second measuring tube, and a water treatment tank. A first measuring valve is installed on the first measuring tube, and a second measuring valve is installed on the second measuring tube. The water treatment device for extracting polysaccharide protein from *Mushroom oyster mushroom* in the aforementioned patent has the following drawbacks: Extraction is performed using an ultrasonic instrument within the water treatment device, which not only increases equipment costs (ultrasonic instrument) but also requires filtering solid residue and collecting the extract after extraction, making the operation rather cumbersome. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a water extraction device for polysaccharide components.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A polysaccharide water extraction device includes a body fixedly connected to the top surface of a support. A cover plate is snapped onto the top of the body. A circular plate is slidably fitted onto the cover plate through a groove on its bottom surface. The top surface of the circular plate is arranged in a ring array with two or more openings. A filter screen is fixedly connected to the bottom end of the opening.

[0007] The machine body is equipped with a pressure filtration and vibration assembly;

[0008] The outer wall of the circular plate is provided with an angle limiting structure.

[0009] As a further embodiment of this utility model: the filter press vibration assembly includes a stud rotatably connected to the inner wall of the bottom of the machine body, a cylinder rotatably connected to the top of the stud, an upper top plate and a lower top plate connected to the outer wall of the stud by threads, a set of T-shaped columns fixedly connected to the top surface of the lower top plate, springs fixedly connected to the corresponding side of the upper and lower top plates that wrap around the T-shaped columns, a guide rod welded to the inner wall of the bottom of the machine body, and two or more rubber hemispheres fixedly connected to one side of the guide rod in a vertical row at equal intervals, wherein the T-shaped columns and the upper top plate form a sliding fit, and the guide rod is inserted into the inner wall of the upper and lower top plates.

[0010] As a further embodiment of this utility model: the bottom outer wall of the machine body is connected to a motor via a support plate, and the output end of the motor is connected to the bottom end of the stud via a coupling;

[0011] The cylinder and the top plate are fixedly connected to the same corrugated cover on their corresponding sides.

[0012] As a further embodiment of this utility model: the outer circumference of the filter screen cover is fixedly connected with two or more metal rings in a vertical row, and a strong magnet ring is fixedly connected to the bottom end of the filter screen cover.

[0013] The top plate is made of iron.

[0014] As a further improvement of this utility model: a liquid inlet is fixedly connected to the outer circumferential wall of the machine body;

[0015] The outer circumferential wall of the machine body is fixedly connected to a liquid outlet.

[0016] As a further embodiment of this utility model: the angle limiting structure includes two or more limiting holes arranged in a ring array on the outer wall of the circular plate, and rubber columns fixedly connected to the inner wall of the machine body in a ring array with the same number of limiting holes. The rubber columns are adapted to the limiting holes, and the upper and lower positions of each rubber column correspond one-to-one with each limiting hole.

[0017] As a further improvement of this utility model: the bottom surface of the circular plate is provided with a bayonet;

[0018] The top surface of the cover plate is fixedly connected to a feed inlet;

[0019] A handle is fixedly connected to the top outer wall of the cover plate.

[0020] As a further improvement of this utility model, a sealing ring is fixedly connected to the inner circumference of the machine body.

[0021] Compared with the prior art, this utility model provides a water extraction device for polysaccharide components, which has the following beneficial effects:

[0022] 1. This polysaccharide water extraction device incorporates a pressure filtration and vibration assembly. As the upper and lower top plates move up and down, the upper plate, upon contact and compression with several rubber hemispheres, generates intermittent up-and-down vibrations in conjunction with spring action. This, in turn, uses hydraulic pressure to agitate the powder within the filter screen, promoting thorough contact between water and the bacterial powder. The upper plate then presses down on the filter screen, forcing the liquid inside to leak out. As the upper plate moves downwards, it stretches the filter screen, allowing the liquid inside to re-enter and mix with the bacterial powder. This process repeats, utilizing multiple up-and-down pressure filtration operations by the upper plate to achieve dynamic pressure filtration of the bacterial powder during extraction. The overall manufacturing cost of this equipment is low, effectively improving the extraction efficiency of polysaccharides and other nutrients from the bacterial powder. It also eliminates the need for subsequent filtration, making it convenient to use and contributing to improved processing efficiency.

[0023] 2. In this polysaccharide water extraction device, after the cover plate is attached to the machine body, the filter screen extends vertically downward under the centrifugal force of the metal ring on top and the strong magnetic ring at the bottom until the strong magnetic ring falls onto the top plate and adheres, thereby sealing the bottom of the filter screen and preventing wild mushroom powder from falling into the machine body.

[0024] 3. This polysaccharide water extraction device involves securing the cover plate to the machine body, especially after the rubber columns are squeezed into the limiting holes on the circular plate. Then, pour an appropriate amount of wild mushroom powder to be extracted into one of the lower filter screens through the feed inlet. Next, hold the handle and rotate the cover plate forcefully at a certain angle. Because the circular plate is restricted, the cover plate rotates around on the circular plate, causing all the rubber columns to disengage from the limiting holes. Stop when the resistance generated by the next round of rubber columns entering the limiting holes is felt. Then, pour another appropriate amount of wild mushroom powder to be extracted into the corresponding lower filter screen through the feed inlet. Repeat this process several times until all filter screens are filled with the wild mushroom powder to be extracted, and then seal the feed inlet. This method is quite convenient to use.

[0033] Example 1

[0034] A water extraction device for polysaccharide components, such as Figure 1-5 As shown, the machine body 2 is fixed to the top surface of the bracket 1 by bolts. The top of the machine body 2 is snapped with a cover plate 10. The top outer wall of the cover plate 10 is fixed with a handle 11 for assisting in disassembling and assembling the cover plate 10 by bolts. The top surface of the cover plate 10 is fixed with an inlet 1001 for introducing wild mushroom powder by bolts.

[0035] Preferably, a rubber sealing ring 13 is welded to the inner circumference of the body 2 to ensure the tightness of the connection between the cover plate 10 and the body 2.

[0036] Furthermore, the cover plate 10 is slidably fitted with a circular plate 14 through a groove 1002 opened on its bottom surface. The top surface of the circular plate 14 is provided with multiple openings 17 in a ring array. A filter screen cover 5 is welded to the bottom end of the openings 17.

[0037] Preferably, the pore size of the filter screen 5 is smaller than the particle size of the wild mushroom powder;

[0038] More preferably, the outer circumference of the filter screen cover 5 is vertically welded with multiple metal rings 501; this increases the load on the filter screen cover 5 and prevents it from tilting or folding during use, which could affect the loading of materials.

[0039] Furthermore, the outer wall of the circular plate 14 is provided with an angle limiting structure. The angle limiting structure includes multiple limiting holes 1401 arranged in a ring array on the outer circumference of the circular plate 14, and rubber pillars 12, which are the same number as the limiting holes 1401 and arranged in a ring array, and are fixed to the inner circumference of the body 2 by bolts. The rubber pillars 12 are adapted to the limiting holes 1401, and the upper and lower positions of each rubber pillar 12 correspond one-to-one with each limiting hole 1401. The setting of the angle limiting structure can help people quickly fill the filter screens 5, making it more convenient to use.

[0040] After the cover plate 10 is secured to the machine body 2, especially after the rubber columns 12 are squeezed into the limiting holes 1401 on the circular plate 14, pour an appropriate amount of wild mushroom powder to be extracted into a filter screen 5 below through the feed inlet 1001. Then, hold the handle 11 and rotate the cover plate 10 by a certain angle. Since the circular plate 14 is restricted, the cover plate 10 can rotate around the circular plate 14, so that all the rubber columns 12 are disengaged from the limiting holes 1401. Stop when you feel the resistance generated by the next round of rubber columns 12 inserting into the limiting holes 1401. At this time, pour an appropriate amount of wild mushroom powder to be extracted into the corresponding filter screen 5 below through the feed inlet 1001. Repeat this operation several times until all the filter screens 5 are filled with wild mushroom powder to be extracted, and then seal the feed inlet 1001.

[0041] like Figure 1-4 As shown, the outer circumference of the machine body 2 is fixed with a liquid inlet 201 for introducing extraction water by bolts; the outer circumference of the machine body 2 is fixed with a liquid outlet 202 for convenient output of the extract by bolts.

[0042] The machine body 2 is equipped with a pressure filtration and vibration assembly. The pressure filtration and vibration assembly includes a stud 8 rotatably connected to the inner wall of the bottom of the machine body 2, a cylinder 801 rotatably connected to the top of the stud 8, an upper top plate 3 and a lower top plate 301 connected to the outer wall of the stud 8 by threads, a set of T-shaped columns 701 welded to the top surface of the lower top plate 301, springs 7 welded to the corresponding sides of the upper top plate 3 and the lower top plate 301 that wrap around the T-shaped columns 701, a guide rod 6 welded to the inner wall of the bottom of the machine body 2, and multiple rubber hemispheres 601 welded vertically and equidistantly to one side of the guide rod 6. The T-shaped columns 701 and the upper top plate 3 form a sliding fit. The guide rod 6 is inserted into the inner wall of the upper top plate 3 and the lower top plate 301.

[0043] Furthermore, a motor 9 is connected to the bottom outer wall of the body 2 via a support plate. The output end of the motor 9 is connected to the bottom end of the stud 8 via a coupling. When the motor 9 is started, the stud 8 is rotated, which causes the upper top plate 3 and the lower top plate 301 to move up and down along the guide rod 6 under the action of the thread. During the upward movement of the upper top plate 3, as it contacts and squeezes against several rubber hemispheres 601, it generates intermittent up and down vibrations in conjunction with the action of the spring 7. This, in turn, uses hydraulic pressure to make the powder inside the filter screen 5 shake, promoting full contact between water and bacterial powder. Furthermore, as the upper top plate 3 and the lower top plate 301 move upwards, the upper top plate 3 presses the filter screen 5, squeezing out the liquid that has seeped into it. As the upper top plate 3 moves downwards, it stretches the filter screen 5, allowing the liquid inside the machine body 2 to seep into it again and mix with the bacterial powder. This process is repeated, and by using the upper top plate 3 to perform multiple up-and-down pressing operations on the filter screen 5, dynamic pressing filtration of the bacterial powder is achieved during the extraction process. This effectively improves the extraction efficiency of nutrients such as polysaccharides in the bacterial powder, while also eliminating the need for subsequent filtration. This makes the process more convenient and helps improve processing efficiency.

[0044] Furthermore, the upper top plate 3 is made of metal iron, and its surface is coated with a prior art anti-corrosion and anti-rust coating; a strong magnetic ring 15 is welded to the bottom of the filter screen cover 5; when the cover plate 10 is attached to the body 2, the filter screen cover 5 spreads vertically downward under the centrifugal force of its upper metal ring 501 and the bottom strong magnetic ring 15 until the strong magnetic ring 15 falls onto the upper top plate 3 and adheres to it, thereby sealing the bottom of the filter screen cover 5 and preventing wild mushroom powder from falling into the body 2.

[0045] As a supplement, the bottom surface of the circular plate 14 is provided with a slot 16 that is adapted to the cylinder 801; the slot 16 is aligned with the cylinder 801 and pressed to install the cover plate 10 onto the body 2.

[0046] Working principle: First, the cover plate 10 is clamped onto the body 2, especially after the rubber column 12 is squeezed into the limiting hole 1401 on the circular plate 14. Under the centrifugal force of the metal ring 501 on it and the strong magnetic ring 15 at the bottom, the filter screen 5 spreads vertically downward until the strong magnetic ring 15 falls onto the top plate 3 and adheres to it, thereby sealing the bottom of the filter screen 5. Next, pour an appropriate amount of wild mushroom powder to be extracted into one of the filter screens 5 below through the feed inlet 1001. Then, hold the handle 11 and rotate the cover plate 10 by a certain angle. Since the circular plate 14 is restricted, the cover plate 10 can rotate around the circular plate 14, causing all the rubber columns 12 to disengage from the limiting hole 1401. Stop when you feel the resistance generated by the next round of rubber columns 12 inserting into the limiting hole 1401. At this time, pour an appropriate amount of wild mushroom powder to be extracted into the corresponding filter screen 5 below through the feed inlet 1001. Repeat this operation several times until all the filter screens 5 are filled with wild mushroom powder to be extracted, and then seal the feed inlet 1001. Finally, pour a suitable amount of extraction water from the liquid inlet 201 to submerge the mushroom powder in the filter screens 5.

[0047] During operation, the starter motor 9 drives the stud 8 to rotate, which in turn causes the upper top plate 3 and lower top plate 301 to move up and down along the guide rod 6 under the influence of the screw thread. As the upper top plate 3 moves upward, its contact and compression with several rubber hemispheres 601, combined with the action of the spring 7, produces intermittent up-and-down vibrations. This, in turn, uses hydraulic pressure to cause the powder inside the filter screen 5 to shake, promoting full contact between water and the bacterial powder. Furthermore, as the upper top plate 3 and lower top plate 301 continuously move up and down, the upper top plate 3 presses the filter screen 5, squeezing out the liquid that has seeped into it. As the upper top plate 3 moves downward, it stretches the filter screen 5, allowing the liquid inside the machine body 2 to seep back in and mix with the bacterial powder. This process repeats itself, using the upper top plate 3 to perform multiple up-and-down pressing operations on the filter screen 5, thereby achieving dynamic pressing filtration of the bacterial powder during extraction. After extraction, control the top plate 3 to move up to the inside of the machine body 2 and export the extract from the outlet 202. Finally, open the cover plate 10 to clean the extracted bacterial powder inside the filter screen 5.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
