Description

Technical Field

[0001] This utility model relates to the field of extraction technology, and in particular to an apparatus for extracting polysaccharides from Phellinus linteus. Background Technology

[0002] Phellinus linteus is a medicinal fungus whose polysaccharides possess various biological activities, including immunomodulatory, antitumor, and antioxidant effects. A combined extraction device for Phellinus linteus polysaccharides is a specialized instrument for the efficient extraction of polysaccharide components from Phellinus linteus. It typically combines multiple extraction techniques to improve the extraction efficiency and purity of the polysaccharides.

[0003] Traditional crushing equipment often uses single-stage crushing, which is difficult to completely destroy the lignified cell walls of Phellinus linteus. This results in insufficient release of polysaccharides during subsequent extraction. Furthermore, the screening of crushed materials relies heavily on static screens, lacking vibration anti-clogging design. The screen holes are easily blocked by debris, leading to uneven output particle size. Unqualified materials need to be manually sorted and re-crushed, increasing labor and time costs. In addition, solid residues often remain in the solid-liquid separation process, resulting in a large amount of extract liquid and low polysaccharide recovery rate, which is difficult to meet the needs of continuous industrial production. Based on this, a device for combined extraction of polysaccharides from Phellinus linteus is proposed for improvement. Utility Model Content

[0004] In view of the problems mentioned above, such as incomplete crushing, easy clogging of sieve holes by debris, the need for manual sorting and re-crushing of unqualified materials, and the frequent presence of a large amount of extract liquid in solid residues, this utility model is proposed.

A first pulley is rotatably connected to the first groove of the double-groove pulley via a first belt. A second crushing blade shaft is fixedly sleeved inside the first pulley.

[0008] As a preferred embodiment, the following configuration is provided: a feeding box is fixedly connected to the inclined bottom end of the screening plate; the feeding box is fixedly connected to one side of the box body; symmetrical feed inlets are provided on one side of the bottom of the feeding box; a second motor is fixedly installed in the mounting groove on the top of the feeding box; an auger is fixedly sleeved on the output shaft of the second motor; the auger is rotatably connected to the conveying chamber inside the feeding box; a conveying pipe is fixedly sleeved on the top of the conveying chamber inside the feeding box; one end of the conveying pipe is connected to the inside of the primary crushing cylinder.

[0009] As a preferred embodiment, a mixing chamber is provided at the bottom of the inner wall of the box, a heating pipe is fixedly installed on the bottom wall of the mixing chamber, and a discharge chute is provided on one side of the mixing chamber.

[0010] As a preferred embodiment, a multi-stage cylinder is fixedly installed on the other side of the housing via a second mounting bracket. The telescopic shaft of the multi-stage cylinder passes through the side wall of the housing and is fixedly connected to a push plate. The push plate is slidably connected to the bottom wall of the mixing chamber.

[0011] As a preferred embodiment, a pressure box is fixedly connected to one side of the mixing chamber where the discharge trough is opened. Electric push rods are symmetrically installed on the top of the pressure box. The telescopic shaft of the electric push rod passes through the top of the pressure box and is fixedly connected to an L-shaped pressure plate. The long plate of the L-shaped pressure plate is slidably connected to the top of the pressure box.

[0014] 1. This utility model employs a multi-stage crushing, vibrating screening, and recycling process design. First, the first and second crushing blades perform two crushing operations on the *Sanghuang* (a type of medicinal mushroom), from coarse to fine grinding, significantly reducing the particle size and providing high-quality raw materials for subsequent polysaccharide extraction, thus significantly improving extraction efficiency. Next, a double-groove pulley drives a cam on the transmission shaft via a second belt, causing the screening plate to vibrate. This effectively prevents screen blockage, ensures smooth screening, improves screening efficiency, and guarantees uniform output particle size. Finally, larger, unqualified particles are returned to the primary crushing cylinder for recycling via an auger and conveyor pipe in the feeding box, ensuring that the final output particle size meets the standards, guaranteeing raw material quality, and stabilizing the polysaccharide extraction effect.

[0015] 2. After mixing, the multi-stage cylinder first scrapes the material in the mixing chamber into the pressing box through the push plate, avoiding the waste of raw materials caused by traditional manual cleaning. The electric push rod drives the L-shaped pressing plate to squeeze the solid residue in the pressing box under high pressure, squeezing out the polysaccharide solution adsorbed in the residue, reducing the problem of "dry residue with liquid". The filter holes on the bottom wall of the pressing box cooperate with the pressing plate to complete the solid-liquid separation. The filtrate is directly collected through the liquid collection pipe without manual transfer, avoiding liquid spillage and loss. The separated solid residue can be quickly poured out through the movable waste door. It can be operated by a single person and avoids the cleaning difficulty caused by residue sticking to the box wall. Attached Figure Description

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Reference Figures 1-4 This is the first embodiment of the present invention, which provides a device for extracting polysaccharides from Sanghuang, including a box body 1, a feed pipe 11 fixedly sleeved at the top of the box body 1, a primary crushing cylinder 12 fixedly sleeved at the bottom of the feed pipe 11, a secondary crushing cylinder 13 fixedly connected to one side of the primary crushing cylinder 12, the primary crushing cylinder 12 and the secondary crushing cylinder 13 being connected to each other, and the box body 1 including a crushing mechanism 2.

[0024] A first motor 22 is fixedly mounted on one side of the housing 1 via a first mounting bracket 21. The output shaft of the first motor 22 is fixedly sleeved with the shaft of the first crusher 24. The first crusher 24 is rotatably connected to the inside of the primary crushing cylinder 12. A double-groove pulley 23 is fixedly sleeved at one end of the primary crushing cylinder 12. The first groove of the double-groove pulley 23 is rotatably connected to the first pulley 26 via a first belt 25. The shaft of the second crusher 27 is fixedly sleeved inside the first pulley 26. The second crusher 27 is rotatably connected to the inside of the secondary crushing cylinder 13.

[0025] A screening plate 3 is fixedly installed in the middle of the inner wall of the box 1. The screening plate 3 is inclined. The second groove of the double groove pulley 23 is rotatably connected to the second pulley 32 through the second belt 31. The drive shaft 33 is fixedly sleeved inside the second pulley 32. Both ends of the drive shaft 33 are rotatably connected to the inner wall of the box 1. Two cams 34 are fixedly sleeved on the outer surface of the drive shaft 33. The cams 34 are located above the screening plate 3.

[0026] A feeding box 4 is fixedly connected to the inclined bottom end of the screening plate 3. The feeding box 4 is fixedly connected to one side of the inside of the box body 1. The feeding box 4 has symmetrical feed inlets on one side of the bottom. A second motor 41 is fixedly installed in the mounting groove on the top of the feeding box 4. An auger 42 is fixedly sleeved on the output shaft of the second motor 41. The auger 42 is rotatably connected to the conveying chamber inside the feeding box 4. A conveying pipe 43 is fixedly sleeved on the top of the conveying chamber inside the feeding box 4. One end of the conveying pipe 43 is connected to the inside of the primary crushing cylinder 12.

[0027] Specifically, the raw material of Sanghuang is fed into the box 1 through the feed pipe 11 at the top of the box 1 and falls into the primary crushing cylinder 12 below. The first motor 22 is started, and its output shaft drives the first crushing blade 24 to perform initial cutting and tearing of the raw material in the primary crushing cylinder 12, breaking the large pieces of Sanghuang into smaller particles.

[0028] The double-groove pulley 23 rotates synchronously with the shaft of the first crusher 24. The first groove of the double-groove pulley 23 drives the first pulley 26 to rotate through the first belt 25, which in turn drives the shaft of the second crusher 27 to rotate, so that the second crusher 27 in the secondary crushing cylinder 13 operates synchronously. The material after preliminary crushing enters the secondary crushing cylinder 13 through the connection between the primary crushing cylinder 12 and the secondary crushing cylinder 13, and is further crushed by the second crusher 27 to further reduce the particle size, which is convenient for subsequent polysaccharide extraction.

[0029] The crushed material falls from the secondary crushing cylinder 13 into the inclined screening plate 3. Fine particles fall through the screen holes into the mixing chamber 14 below the box body 1. At the same time, the second groove of the double groove pulley 23 drives the second pulley 32 to rotate through the second belt 31, which in turn drives the transmission shaft 33 to rotate. The cam 34 rotates synchronously with the transmission shaft 33, periodically impacting the top of the screening plate 3, causing the screening plate 3 to vibrate. This causes larger particles to slide along the inclined surface of the screening plate 3 to the feed inlet at the bottom of the feeding box 4, preventing the screen holes from being blocked by materials and ensuring screening efficiency.

[0030] Next, the second motor 41 is started, and its output shaft drives the auger 42 to rotate, which transports the material in the conveying chamber back to the primary crushing cylinder 12 through the conveying pipe 43, and crushes it again together with the newly added raw materials, thereby realizing the recycling of unqualified materials.

[0031] This design, on the one hand, uses the first crushing blade 24 and the second crushing blade 27 to crush Sanghuang twice, from coarse crushing to fine pulverization, which can significantly reduce the particle size of the material, provide high-quality raw materials for subsequent polysaccharide extraction, and significantly improve the extraction efficiency. On the other hand, the double-groove pulley 23 drives the cam 34 on the transmission shaft 33 through the second belt 31, causing the screening plate 3 to vibrate, effectively preventing screen hole blockage, ensuring a smooth screening process, improving screening efficiency, and ensuring uniform output particle size. Finally, the larger particles that do not meet the standards are sent back to the primary crushing cylinder 12 for recycling through the auger 42 and conveying pipe 43 in the feeding box 4, ensuring that the final output particle size meets the standards, guaranteeing the quality of raw materials, and stabilizing the polysaccharide extraction effect.

[0032] Reference Figures 1-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a mixing chamber 14 is provided at the bottom of the inner wall of the box 1, a heating pipe is fixedly installed on the bottom wall of the mixing chamber 14, and a discharge chute is provided on one side of the mixing chamber 14.

[0033] On the other side of the housing 1, a multi-stage cylinder 51 is fixedly installed by a second mounting bracket 5. The telescopic shaft of the multi-stage cylinder 51 passes through the side wall of the housing 1 and is fixedly connected to a push plate 52. The push plate 52 is slidably connected to the bottom wall of the mixing chamber 14.

[0034] A pressure box 6 is fixedly connected to one side of the mixing chamber 14 where the discharge trough is opened. Electric push rods 62 are symmetrically installed on the top of the pressure box 6. The telescopic shaft of the electric push rod 62 passes through the top of the pressure box 6 and is fixedly connected to an L-shaped pressure plate 63. The long plate of the L-shaped pressure plate 63 is slidably connected to the top of the pressure box 6. The area of ​​the long plate of the L-shaped pressure plate 63 is larger than the area of ​​the discharge trough of the mixing chamber 14.

[0035] The bottom wall of the pressing box 6 has several filter holes, the bottom end of the pressing box 6 is fixedly connected to the liquid collection pipe 64, and the side of the pressing box 6 is movably connected to the impurity outlet door 61.

[0036] Specifically, the mixing chamber 14 is equipped with a heating tube, which can uniformly mix and heat the qualified materials. Heating can accelerate the breaking of Phellinus linteus cells, promote the dissolution of polysaccharide components, improve the extraction rate, and provide a better mixture for subsequent separation processes.

[0037] After mixing is completed, the electric push rod 62 is activated first, driving the L-shaped pressure plate 63 to rise first, and then opening the discharge chute on one side of the mixing chamber 14. Most of the mixed liquid and solid residue will flow into the pressure box 6. The mixed liquid flows out and is collected through the collection pipe 64 through several filter holes on the bottom wall of the pressure box 6, while the solid residue is left inside the pressure box 6.

[0038] Next, the multi-stage cylinder 51 is activated, and the telescopic shaft pushes the push plate 52 to slide on the bottom wall of the mixing chamber 14, pushing the remaining liquid and solid residue inside the mixing chamber 14 into the pressing box 6. When the push plate 52 moves to the discharge chute on one side of the mixing chamber 14, the discharge chute is blocked.

[0039] Then, the L-shaped pressure plate 63 is driven down by the electric push rod 62 to squeeze out the remaining mixed liquid in the solid residue. The liquid flows out and is collected through several filter holes on the bottom wall of the pressure box 6 and then through the liquid collection pipe 64. Finally, the separated solid residue can be cleaned through the movable impurity door 61.

[0040] After mixing, the multi-stage cylinder 51 first scrapes the material in the mixing chamber 14 into the pressing box 6 through the push plate 52, avoiding the waste of raw materials caused by traditional manual cleaning. The electric push rod 62 drives the L-shaped pressing plate 63 to press the solid residue in the pressing box 6 under high pressure, squeezing out the polysaccharide solution adsorbed in the residue and reducing the problem of "dry residue with liquid". The filter holes on the bottom wall of the pressing box 6 work with the pressing plate to complete the solid-liquid separation. The filtrate is collected directly through the liquid collection pipe 64 without manual transfer, avoiding liquid spillage and loss. The separated solid residue can be quickly poured out through the movable waste discharge door 61. It can be operated by a single person and avoids the cleaning difficulty caused by residue sticking to the box wall.
