A device for extracting nutrients from Spartina alterniflora

Abstract

This utility model belongs to the technical field of plant nutrient extraction equipment, and particularly relates to a device for extracting nutrients from Spartina alterniflora. The device includes a main body, which is fixedly installed on the ground by a support frame. An end cap is movably installed on the top of the main body, and the end cap has a feed inlet. In this Spartina alterniflora nutrient extraction device, the pretreatment chamber has heating coils on both sides of the cavity, allowing for temperature adjustment and uniform heating of the mixture as needed, promoting the full release of effective components.

Description

Technical Field

[0001] This utility model relates to the technical field of plant nutrient extraction equipment, specifically a device for extracting nutrients from Spartina alterniflora. Background Technology

[0002] Spartina alterniflora, a common herbaceous plant, is rich in various nutrients such as protein, polysaccharides, and flavonoids, and has high application value in feed, health products, and other fields. Currently, existing Spartina alterniflora nutrient extraction devices have the following shortcomings. On the one hand, most existing devices only use a single filtration method (such as simple natural filtration or simple pressure filtration), lacking a synergistic filtration system of plant nutrient extraction equipment, which includes "heated solubilization plant nutrient extraction equipment - negative pressure filtration plant nutrient extraction equipment - centrifugal fine filtration plant nutrient extraction equipment". This not only fails to adapt the treatment to the dissolution characteristics of different nutrients in Spartina alterniflora, resulting in incomplete dissolution of effective components, but also makes it difficult to remove small particulate impurities due to the limited precision of single filtration, resulting in low purity of the extract and poor nutrient extraction rate.

[0003] On the other hand, existing devices are inconvenient to clean, often requiring manual disassembly to remove residues after filtration. This is labor-intensive, time-consuming, and often results in incomplete cleaning, leading to residue buildup that clogs equipment channels and contaminates subsequent extraction materials. This shortens the equipment's lifespan and severely impacts the efficiency and purity of subsequent extraction operations, making it difficult to meet the demand for efficient and high-quality extraction of nutrients from Spartina alterniflora. Therefore, there is an urgent need to improve a Spartina alterniflora nutrient extraction device to solve these problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for extracting nutrients from Spartina alterniflora, comprising a main body, which is fixedly installed on the ground by a support frame, and an end cap is movably installed on the top of the main body, with a feed inlet on the end cap; the device for extracting nutrients from Spartina alterniflora includes a filtration mechanism and a cleaning mechanism, the filtration mechanism including the main body, the main body having a pretreatment chamber inside, the pretreatment chamber having a double-sided structure with a cavity inside, and a heating coil inside the cavity.

[0006] Preferably, a filtration chamber is provided below the pretreatment chamber, an air inlet pipe is provided on the main body of the device between the filtration chamber and the pretreatment chamber, and an air extraction pipe is provided on the main body of the device below the filtration chamber. The air inlet pipe is fixedly installed at the outlet of the gas circulation pump, and the air extraction pipe is fixedly installed at the air extraction port of the filtration chamber.

[0007] Preferably, a feeding pipe is provided directly below the main body of the device, and the end of the feeding pipe is located inside the centrifuge drum. A centrifuge motor is provided at the bottom of the centrifuge, and the output shaft of the centrifuge motor is fixedly connected to the center of the centrifuge drum. A collection bin is located between the centrifuge drum and the centrifuge, and a discharge pipe with a one-way valve is provided at its bottom. Here, the centrifuge motor is model YE2-112M-2.

[0008] Preferably, the cleaning mechanism includes an end cap, on which a mounting base is fixedly installed, and on which a hydraulic cylinder is fixedly installed. The output end of the hydraulic cylinder passes through the mounting base and is fixedly connected to a motor. A slider is provided on the back of the motor, and the mounting base is provided with a sliding groove to cooperate with its up and down movement. Here, the motor model is 45ZY68.

[0009] Preferably, the drive shaft of the motor passes through the end cover and has four sets of scrapers fixedly installed at its end. The scrapers are located between the pretreatment chamber and the filtration chamber. A sealing gasket is movably installed on the drive shaft, and the size of the sealing gasket is the same as the size of the discharge port of the pretreatment chamber.

[0010] Preferably, two sets of cylinders are fixedly installed below the pretreatment chamber. The output end of the cylinders is fixedly installed on the mounting plate. The mounting plate is provided with two sets of arc-shaped grooves. A limit ring is fixedly installed in the middle of the arc-shaped grooves. A pusher plate is movably installed on the limit ring. The cylinders are controlled by an external control cabinet.

[0011] Preferably, the lower edge of the pusher plate contacts the waste collection trough, the pusher plate is a slope, the waste collection trough is located between the filtration chamber and the inner wall of the main body of the device, and a waste outlet is provided at its bottom end. A baffle controlled by a cylinder is provided on the outside of the waste outlet.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This Spartina alterniflora nutrient extraction device, through its filtration mechanism design, features a pretreatment chamber with a double-sided cavity structure and built-in heating coils. This allows for uniform heating of the Spartina alterniflora fragment mixture, and the temperature can be adjusted according to the dissolution requirements of different nutrients, promoting the full release of effective components and avoiding incomplete dissolution caused by uneven local heating. The filtration chamber, connected to a gas circulation pump via an air inlet pipe and its own air extraction port, creates a stable negative pressure filtration environment, rapidly separating solids and liquids, reducing the retention and loss of extract in residues, and dynamically adjusting the filtration process through gas circulation to adapt to mixtures of different concentrations. The filtered extract enters the centrifuge tank via a feed pipe, where centrifugal force performs secondary fine separation to remove residual micro-impurities, improve the purity of the extract, and enhance the extraction rate and quality of nutrients.

[0014] 2. This Spartina alterniflora nutrient extraction device, through the design of its cleaning mechanism, allows the hydraulic cylinder to drive the motor downwards after pretreatment, causing the sealing gasket to detach from the pretreatment chamber and allowing the mixed liquid to flow smoothly into the filtration chamber. At the same time, the scraper adheres to the filtration chamber. After filtration, the motor drives the scraper to rotate, using centrifugal force to throw the residue into the waste collection tank. Subsequently, the cylinder below the pretreatment chamber starts to drive the mounting plate downwards, causing the pusher plate to push the residue along the slope of the collection tank to the outlet for discharge. This process does not require manual disassembly, reducing operational intensity and cleaning time, minimizing equipment contamination and clogging, extending equipment life, and ensuring the purity and efficiency of subsequent extraction.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Based on Example 1, existing devices mostly employ only a single filtration method (such as simple natural filtration or simple pressure filtration), lacking a synergistic filtration system for plant nutrient extraction equipment, which combines "heated solubilization plant nutrient extraction equipment - negative pressure filtration plant nutrient extraction equipment - centrifugal fine filtration plant nutrient extraction equipment." This not only fails to adapt the treatment to the different dissolution characteristics of Spartina alterniflora nutrients, resulting in incomplete dissolution of effective components, but also, due to the limited precision of single filtration, it is difficult to remove small particulate impurities, leading to low purity of the extract and poor nutrient extraction rate. Therefore, this device incorporates a combined filtration mechanism to solve the above problems. Please refer to [link / reference]. Figures 1-2 This utility model provides a technical solution: a device for extracting nutrients from Spartina alterniflora, including a device body 1, which is fixedly installed on the ground by a support frame. An end cap 2 is movably installed on the top of the device body 1, and the end cap 2 is provided with a feed inlet 3. The device for extracting nutrients from Spartina alterniflora includes a filtration mechanism and a cleaning mechanism. The filtration mechanism includes the device body 1. The device body 1 has a pretreatment chamber 201 inside. The pretreatment chamber 201 has a double-sided structure and a cavity 202 inside. A heating coil 203 is provided inside the cavity 202.

[0024] Below the pretreatment chamber 201 is a filtration chamber 204. The main body 1 of the device between the filtration chamber 204 and the pretreatment chamber 201 is provided with an air inlet pipe 205. Below the filtration chamber 204, the main body 1 of the device is provided with an air extraction pipe 206. The air inlet pipe 205 is fixedly installed at the outlet of the gas circulation pump 8, and the air extraction pipe 206 is fixedly installed at the air extraction port of the filtration chamber 204.

[0025] The main body 1 of the device is provided with a feeding pipe 5 at its bottom. The end of the feeding pipe 5 is located in the centrifuge barrel 207 inside the centrifuge 6. The centrifuge 6 is provided with a centrifuge motor at its bottom. The output shaft of the centrifuge motor is fixedly connected to the center of the centrifuge barrel 207. The centrifuge barrel 207 and the centrifuge 6 are connected to a collection bin 208, and the bottom of the collection bin 208 is provided with a discharge pipe 7 with a one-way valve.

[0026] The operator feeds the pretreated Spartina alterniflora fragments (a mixture of fragments and extraction solvent) into the pretreatment chamber 201 inside the main body 1 of the device through the feed inlet 3. At this time, the sealing gasket 312 is closed, fitting against the feed inlet of the pretreatment chamber 201 to ensure that the raw material is completely retained in the pretreatment chamber and to prevent leakage. The heating coil 203 in the cavity 202 generates heat after being energized, and heats the raw material mixture in the chamber evenly through double-sided heating. The operator can then select the appropriate nutrient components (such as polysaccharides) based on the desired composition. The dissolution characteristics of flavonoids, etc. are analyzed, and the power of the heating coil is adjusted to control the temperature inside the chamber. After pretreatment, the hydraulic cylinder 301 is activated, and its output end pushes the motor 305 to move downward along the slide groove 303 of the mounting base 302. The motor 305 drives the drive shaft 306 to move downward synchronously, so that the sealing gasket 312 on the drive shaft is disengaged from the discharge port of the pretreatment chamber 201. The pretreated mixture flows into the lower suction filtration chamber 204 under the action of gravity. At the same time, the gas circulation pump 8 is activated, and the gas circulation pump flows through the air inlet pipe 20 Gas is injected into the space between the filtration chamber 204 and the pretreatment chamber 201, while the suction pipe 206 below the filtration chamber 204 continuously draws in air, creating a stable negative pressure environment inside the filtration chamber. Under the action of negative pressure, the liquid components in the mixture quickly pass through the filtration structure of the filtration chamber and flow into the centrifuge 6 through the feed pipe 5 directly below the main body of the device 1. Solid residues are retained in the filtration chamber, achieving preliminary solid-liquid separation. The liquid flowing into the centrifuge 6 enters the centrifuge tank 207, and the centrifuge motor at the bottom of the centrifuge is started. The motor output shaft drives the centrifuge tank 207 to rotate at high speed. Under the action of centrifugal force, the tiny solid impurities remaining in the liquid are thrown towards the inner wall of the centrifuge tank, while the pure nutrient extract is collected in the collection bin 208 between the centrifuge tank and the centrifuge shell. The discharge pipe 7 at the bottom of the collection bin 208 is equipped with a one-way valve to prevent the extract from flowing back. When the extract in the collection bin reaches a certain amount, the one-way valve is opened, and the extract is discharged through the discharge pipe 7 to enter the subsequent purification or storage process, thus completing the extraction and purification of nutrients.

[0027] Example 2:

[0028] Based on Example 1, existing devices suffer from inconvenient residue cleaning, often requiring manual disassembly to remove post-filtration residue. This is labor-intensive, time-consuming, and prone to incomplete cleaning, leading to residue buildup that clogs equipment channels and contaminates subsequent extraction materials. This shortens equipment lifespan and severely impacts the efficiency and purity of subsequent extraction operations, failing to meet the demands for efficient and high-quality extraction of Spartina alterniflora nutrients. Therefore, this device incorporates a cleaning structure to address these issues. Please refer to [link to relevant documentation]. Figures 3-5 This utility model provides a technical solution: a device for extracting nutrients from Spartina alterniflora, the cleaning mechanism including an end cap 2, an mounting base 302 fixedly mounted on the end cap 2, a hydraulic cylinder 301 fixedly mounted on the mounting base 302, the output end of the hydraulic cylinder 301 passing through the mounting base 302 and fixedly connected to a motor 305, a slider 304 provided on the back of the motor 305, and a groove 303 provided on the mounting base 302 to cooperate with its up and down movement.

[0029] The drive shaft 306 of the motor 305 passes through the end cover 2 and four sets of scrapers 307 are fixedly installed at its end. The scrapers 307 are located between the pretreatment chamber 201 and the filtration chamber 204. A sealing gasket 312 is movably installed on the drive shaft 306. The size of the sealing gasket 312 is the same as the size of the discharge port of the pretreatment chamber 201.

[0030] Two sets of cylinders 309 are fixedly installed below the pretreatment chamber 201. The output end of the cylinders 309 is fixedly installed on the mounting plate 310. The mounting plate 310 is provided with two sets of arc grooves 313. A limit ring 314 is fixedly installed in the middle position of the arc groove 313. A pusher plate 311 is movably installed on the limit ring 314.

[0031] The lower edge of the pusher plate 311 contacts the waste collection trough 308 and has the same width. The waste collection trough 308 is a symmetrical slope on both sides. The waste collection trough 308 is located between the filter chamber 204 and the inner wall of the main body 1 of the device. The bottom end of the waste collection trough 4 is provided with a waste outlet 4. The outer side of the waste outlet 4 is provided with a baffle controlled by a cylinder.

[0032] After filtration and centrifugation are completed, the motor 305 is started. The motor drive shaft 306 drives the four sets of scrapers 307 at the end to rotate. The scrapers 307 adhere to the inner wall of the filtration chamber 204 and scrape off the solid residue trapped in the filtration chamber. Under the action of gravity and the rotational force of the scrapers, the residue falls into the waste collection tank 308 between the filtration chamber 204 and the inner wall of the main body 1. The two sets of cylinders 309 below the pretreatment chamber 201 are started. The output end of the cylinder pushes the mounting plate 310 downward. The mounting plate 310 is provided with two sets of arc-shaped grooves 313. The limiting ring 314 in the middle of the arc-shaped groove guides the pusher plate 311. When the mounting plate moves downward, it drives the pusher plate 311. Plate 311 slides along the slope of waste collection trough 308, pushing the residue in the trough towards the waste outlet 4 at the lowest end of the waste collection trough. A baffle controlled by a cylinder is provided on the outside of waste outlet 4. When the pusher plate pushes the residue to the waste outlet, the cylinder controlling the baffle starts, opens the baffle, and the residue is discharged out of the device through waste outlet 4. After discharge, the cylinder drives the mounting plate 310 to reset, and the pusher plate 311 resets under the action of spring 315. The hydraulic cylinder 301 drives the motor 305 and the sealing gasket 312 to move upward, so that the sealing gasket re-closes the discharge port of the pretreatment chamber 201, and the device returns to the initial state, ready for the next batch of extraction.
