Description

Technical Field

[0001] This invention relates to the field of plant dyeing extraction technology, specifically to a device and process for extracting ultrafine cashmere and velvet plant dyes. Background Technology

[0002] The dyeing of ultrafine cashmere and silk blends with natural plant dyes is a cutting-edge technology in the luxury textile industry. Natural plant dyes (such as madder, sappanwood, gardenia, indigo, and cochineal) are gradually replacing some synthetic dyes in high-end textiles due to their natural origin, biodegradability, human-friendly properties, and alignment with sustainable zero-carbon principles. However, natural plant dyes generally suffer from inherent defects such as low dye uptake, insufficient color fastness, and unstable batch-to-batch reproducibility. One of the root causes of these problems is the inefficiency and uniformity of the dye extraction process. Existing low-temperature extraction devices generally use stirring paddles to mechanically mix plant debris and extraction solvents in order to promote the diffusion and transfer of pigment molecules from the solid phase to the liquid phase by enhancing convection. To protect the activity of heat-sensitive pigments, the extraction temperature is usually controlled in the range of 40-60°C, and the stirring speed is set low to avoid violent shearing that damages the structure of pigment molecules. However, in actual production, after the plant raw materials are crushed, the particle size distribution is extremely wide, and the density of different tissue parts varies significantly. When the debris is added to the extraction solvent, the lighter components (such as epidermal villi and thin-walled cell fragments) float rapidly to the surface because their density is lower than that of the solvent, gradually accumulating to form a floating layer; while the heavier components (such as lignocellulose and vascular tissue) sink to the bottom of the tank because of their higher density, gradually accumulating into a dense sediment layer. The lighter debris near the liquid surface is exposed to the gas-liquid interface for a long time, and only relies on weak surface fluctuations to contact the solvent. The diffusion rate of its pigments to the bulk is extremely slow, and at the same time, due to buoyancy, it is difficult to... The heavy debris at the bottom of the tank is drawn into the main flow field by the downward-entered jet to participate in the circulation. Under the action of the conventional flow field of the stirring blade, the heavy debris at the bottom of the tank cannot be effectively disturbed due to the fixed distance between the blade and the bottom and the significant attenuation of the flow velocity in the bottom area. Instead, it forms a physical barrier, which hinders the downward penetration of the upper solvent. This makes the solvent exchange inside the sediment almost stagnant. Only the surface debris can release some pigment, while the internal debris is in a supersaturated microenvironment for a long time, making it difficult for the pigment release process to continue. This affects the quality and efficiency of plant raw material extraction. To this end, we propose an ultrafine velvet cashmere plant dyeing extraction device and extraction process. Summary of the Invention

[0007] Preferably, a sliding sleeve is slidably mounted on the rotating shaft, an annular plate frame is fixedly mounted on the rotating shaft, and a return spring is connected between the bottom of the sliding sleeve and the top of the annular plate frame. Multiple support rods are fixedly mounted on the sliding sleeve, and an action protrusion is fixedly mounted at one end of each support rod. The ball bearing at the top of the connecting shaft is located on the movement trajectory of the action protrusion. The action protrusion includes an inclined action area and a planar action area.

[0008] Preferably, a protective sleeve is also fixedly installed on the rotating shaft, and an electromagnet is fixedly installed on the inner wall of the top of the protective sleeve. A magnetic shaft is fixedly installed on the top of the sliding sleeve, with one end of the magnetic shaft located inside the protective sleeve. The electromagnet is energized to generate a repulsive force on the magnetic shaft.

[0009] Preferably, the bottom of the soaking sleeve is provided with a closed plate frame, and multiple positioning sleeves are fixedly installed on the outer wall of the soaking sleeve. Multiple limiting shafts corresponding to the positioning sleeves are fixedly installed on the closed plate frame. One end of the limiting shaft is located inside the positioning sleeve and is slidably connected to its inner wall. A constant force spring is connected between the limiting shaft and the bottom inner wall of the positioning sleeve. A force-bearing shaft is also fixedly installed at the center of the closed plate frame, and one end of the force-bearing shaft is located at the discharge port of the intercepting plate.

[0010] Preferably, a support sleeve is also provided above the lifting plate and fixedly installed on the rotating shaft, and multiple connecting sleeves are fixedly installed on the support sleeve. A steel shaft is rotatably installed inside the connecting sleeve. One end of the steel shaft is located outside the connecting sleeve, and an arc-shaped concave blade is fixedly installed at the end of the steel shaft located outside the connecting sleeve.

[0011] Preferably, the outer wall of the arc-shaped concave blade is fitted with a tapered silicone flow channel, and the arc-shaped concave blade has a through hole communicating with the tapered silicone flow channel.

[0012] Preferably, a movable sleeve is slidably connected inside the connecting sleeve, and an arc-shaped groove is formed on the inner wall of the movable sleeve. A steel ball is also embedded at one end of the steel shaft inside the connecting sleeve. The steel ball slides within the arc-shaped groove and is limited in position. A spring mechanism is connected between the end of the movable sleeve and the inner wall of the connecting sleeve.

[0013] An extraction process for an ultrafine cashmere dyeing extraction device specifically includes the following steps: S1. Add plant debris and extraction solvent into the tank to the preset liquid level, start the servo motor, the servo motor drives the rotating shaft to rotate, and the rotating shaft drives the guide blade, stirring blade, lifting plate, support sleeve, connecting sleeve and arc-shaped concave blade to rotate synchronously. S2. The guide blades push the light debris floating on the liquid surface into the soaking sleeve through the guide channel formed between the arc-shaped guide plates. The sliding sleeve rotates with the shaft and drives the action protrusion. The action protrusion acts on the ball bearings. The connecting shaft drives the pressure plate to descend. The pressure plate first drives the baffle to seal the opening, and then continues to descend to approach the interception plate. The liquid is drained through the filter holes and the light debris is intercepted below the interception plate. S3. After extraction, the electromagnet is energized and generates a repulsive force on the magnetic shaft. The magnetic shaft pushes the sliding sleeve down and compresses the return spring. The sliding sleeve lowers the pressure plate to fit with the interception plate through the action protrusion. The pressure plate pushes the force-bearing shaft and drives the closed plate frame down. The bottom of the soaking sleeve opens to allow light debris and residual liquid to be discharged. S4. The rotating shaft drives the connecting sleeve to rotate synchronously. The moving sleeve slides along the inner wall of the connecting sleeve under centrifugal force and stretches the spring mechanism. The arc-shaped groove on the inner wall of the moving sleeve applies force to the steel ball, thereby causing the steel shaft to rotate and the arc-shaped concave blade to adjust the angle of the material. The lifting plate lifts up the heavy debris deposited at the bottom. The heavy debris enters the tapering silicone flow channel through the through hole and is squeezed out. The rotating shaft rotates intermittently in the opposite direction to avoid blockage in the tapering silicone flow channel. S5. When the electromagnet is de-energized, the sliding sleeve rises and resets under the action of the reset spring, the pressure plate rises and resets under the action of the spring, and the force-bearing shaft drives the closing plate frame to rise and reset under the action of the constant force spring and re-closes the bottom of the soaking sleeve. S6. Repeat S2 to S5 to achieve continuous extraction. After extraction is complete, rinse the soaking sleeve and the closed plate rack to remove residual debris.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses guide paddles to push lightweight debris floating on the liquid surface, allowing it to enter the soaking sleeve through a flow channel. Combined with the physical sealing of the opening by a baffle when the pressure plate is pressed down, and the discharge of liquid through filter holes during the continuous pressing of the pressure plate, the lightweight debris is precisely trapped below the interception plate. Simultaneously, during the discharge stage, the repulsive force of an electromagnet drives the sliding sleeve downwards, causing the pressure plate to push the force-bearing shaft to open the bottom of the closed plate frame. This achieves automatic flow guidance, precise interception, filtrate separation, and automatic discharge of lightweight debris, solving the problem that lightweight plant debris easily accumulates and lingers on the liquid surface, making it difficult to integrate into the main body of the extract. 2. This invention uses a lifting plate to lift heavy debris deposited at the bottom of the tank, and the movable sleeve inside the connecting sleeve slides outward under centrifugal force. The steel shaft is driven to rotate through the arc-shaped groove, so that the arc-shaped concave blades automatically adjust to the optimal angle of material reception, guiding the heavy debris into the tapered silica gel channel for physical extrusion and discharge. At the same time, the intermittent reverse rotation of the rotating shaft effectively eliminates the blockage caused by debris entanglement in the tapered silica gel channel.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-13This invention provides a technical solution: an ultra-fine velvet cashmere plant dyeing extraction device and extraction process, including a tank body 1 and a tank cover 2 that fits and covers the top of the tank body 1. A servo motor 21 is fixedly installed on the top of the tank cover 2. The output end of the servo motor 21 extends into the tank body 1. A rotating shaft 3 is fixedly connected to the output end of the servo motor 21. The rotating shaft 3 passes through the inside of the tank body 1. A guide blade 4, a stirring blade 7, and a lifting plate 6 are installed on the rotating shaft 3 from top to bottom along its axial direction. The position of the guide blade 4 is adapted to the liquid level set in the subsequent soaking process. That is, the guide blade 4 is set at the liquid level at the same height as the extraction liquid level. The stirring blade 7 is located in the vertical middle area of ​​the tank body 1 to be responsible for the uniform mixing and convection of the main extraction solvent in the tank body 1. The lifting plate 6 is fixedly installed at the bottom end of the rotating shaft 3 and close to the bottom of the tank body 1. This top-down layered arrangement can carry out corresponding guiding and collection operations for plant debris of different densities, greatly improving the processing efficiency of debris of different densities. Multiple soaking sleeves 5 are fixedly installed on the inner wall of the tank 1. The top of the soaking sleeve 5 has an opening 51. The area of ​​the top opening 51 of the soaking sleeve 5 is used to collect light plant debris floating on the liquid surface. Two arc-shaped guide plate frames 52 are fixedly installed on the top of the soaking sleeve 5. A flow channel 521 for guiding the entry is formed between the two arc-shaped guide plate frames 52. The outer edge of the arc-shaped guide plate frame 52 extends in a natural direction. This expansion-shaped flow guide design can ensure that when the rotating guide blade 4 pushes the debris on the liquid surface, the liquid flow can smoothly flow into the interior of the soaking sleeve 5. A retaining plate 53 is fixedly installed on the inner wall of the soaking sleeve 5. The retaining plate 53 has an inwardly contracting inclined structure. The inlet end orifice diameter of the retaining plate 53 is consistent with the inner diameter of the soaking sleeve 5, while the outlet end orifice diameter of the retaining plate 53 is smaller than the inlet end orifice diameter. This inclined constriction design can effectively prevent the light debris collected below the retaining plate 53 from floating upward and back, ensuring the stability of the debris position during the collection process.

[0019] The soaking sleeve 5 is uniformly provided with multiple filter holes 56 for filtering liquid in the area below the intercepting plate 53. The opening diameter of the filter holes 56 is smaller than the particle size of the light plant debris to avoid the light debris being lost with the discharged liquid. A closed plate frame 58 is provided at the bottom of the soaking sleeve 5. Multiple positioning sleeves 59 are fixedly installed on the outer wall of the soaking sleeve 5. A limiting shaft 581 is fixedly installed on the closed plate frame 58. One end of the limiting shaft 581 extends into the positioning sleeve 59 and slides in connection with its inner wall. A constant force spring 50 is connected between the bottom inner wall of the positioning sleeve 59 and the limiting shaft 581. Under the action of the constant force spring 50, the closed plate frame 58 is tightly attached to the bottom of the soaking sleeve 5 under normal conditions, thereby sealing the bottom opening of the soaking sleeve 5. A force-bearing shaft 501 is also fixedly installed in the center of the closed plate frame 58. The top end of the force-bearing shaft 501 extends upward to the discharge port of the intercepting plate 53.

[0020] A pressure plate 54 is provided above the soaking sleeve 5. A baffle 542 is slidably installed on the pressure plate 54. Outwardly extending supports 543 are symmetrically arranged on the baffle 542. Guide shafts 544 are symmetrically fixedly installed on the top of the pressure plate 54. A spring body 545 sleeved on the outer periphery of the guide shaft 544 is connected between the supports 543 and the top of the pressure plate 54. The opening 51 is located on the movement trajectory of the baffle 542 as the pressure plate 54 descends. A support plate 55 is fixedly installed on the top of the soaking sleeve 5. The top of the pressure plate 54 is fixedly installed. A connecting shaft 541 is fixedly installed, extending upward and passing through the support plate 55. A freely rolling ball 546 is embedded at the top of the connecting shaft 541. A spring part 57 is sleeved on the outer periphery of the connecting shaft 541 below the support plate 55. One end of the spring part 57 abuts against the connecting shaft 541 and the other end abuts against the support plate 55. The pressure plate 54 is pressed down smoothly as a whole by the up and down sliding of the connecting shaft 541 in the support plate 55. At the same time, the spring part 57 can complete the reset of the pressure plate 54 after the external force is removed.

[0021] A sliding sleeve 31 is slidably mounted on the rotating shaft 3. An annular plate frame 32 is fixedly mounted on the outer wall of the rotating shaft 3. A return spring 33 is connected between the bottom of the sliding sleeve 31 and the top of the annular plate frame 32. Multiple horizontally extending support rods 34 are fixedly mounted on the outer periphery of the sliding sleeve 31. An action protrusion 35 is fixedly mounted on the end of each support rod 34 away from the sliding sleeve 31. The action protrusion 35 includes an inclined action area 351 and a planar action area 352. The inclined action area 351 has a gradually changing slope along the circumference. The tail end of the slope smoothly transitions to the planar action area 352. (The last sentence appears to be incomplete and possibly refers to a ball bearing position.) On the circumferential rotation trajectory of the actuating protrusion 35, that is, when the rotating shaft 3 drives the sliding sleeve 31 to rotate, the support rod 34 drives the actuating protrusion 35 to sweep across the top of the connecting shaft 541. A protective sleeve 36 covering the sliding sleeve 31 is also fixedly installed on the rotating shaft 3. An electromagnet 361 is fixedly installed on the inner wall of the top of the protective sleeve 36. A magnetic shaft 311 extending upward into the protective sleeve 36 is fixedly installed on the top of the sliding sleeve 31. After the electromagnet 361 is energized, it generates a repulsive force on the magnetic shaft 311, thereby pushing the sliding sleeve 31 to move downward against the elastic force of the return spring 33.

[0022] In the lower region of the rotating shaft 3, a support sleeve 8 is fixedly installed above the lifting plate 6. Multiple connecting sleeves 81 are fixedly installed on the outer periphery of the support sleeve 8. A steel shaft 82 is rotatably installed inside the connecting sleeve 81. One end of the steel shaft 82 extends to the outside of the connecting sleeve 81 and is fixedly installed with an arc-shaped concave blade 83. The outer wall of the arc-shaped concave blade 83 is covered with a tapered silicone flow channel 84. A through hole 831 communicating with the inside of the tapered silicone flow channel 84 is opened on the wall of the arc-shaped concave blade 83. The inlet end of the inner cavity of the tapered silicone flow channel 84 is larger than the outlet end. With the gradual structure of large inlet and small outlet, heavy plant debris can be physically squeezed when passing through the tapered silicone flow channel 84. Inside the connecting sleeve 81, a movable sleeve 85 is also slidably installed. The inner wall of the movable sleeve 85 is provided with a spiral arc groove 851. A steel ball 821 is embedded in one end of the steel shaft 82 located inside the connecting sleeve 81. The steel ball 821 slides within the arc groove 851. A spring mechanism 86 is connected between the end of the movable sleeve 85 and the inner end wall of the connecting sleeve 81. When the rotating shaft 3 drives the supporting sleeve 8 to rotate at high speed, the movable sleeve 85 moves outward due to centrifugal force. The rotation of the steel shaft 82 is realized through the transmission cooperation between the steel ball 821 and the arc groove 851, which automatically completes the dynamic adjustment of the angle of the arc concave blade 83 to meet the material. After the centrifugal force disappears, it is pulled back to its original position by the spring mechanism 86.

[0023] Specifically, during the low-temperature extraction process, the plant debris required for ultrafine cashmere dyeing is first placed into the tank 1, and the low-temperature extraction solvent is injected to the set liquid level. Then, the servo motor 21 is started, and the output of the servo motor 21 drives the rotating shaft 3 to rotate in the set direction. During the rotation of the rotating shaft 3, the guide blade 4 located at the liquid level, the stirring blade 7 located in the middle of the tank, the lifting plate 6 located at the bottom, the support sleeve 8 at the bottom, the connecting sleeve 81, and the arc-shaped concave blade 83 are rotated synchronously. The stirring blade 7 slowly stirs the main solvent to promote the uniform diffusion of the solute. When the guide blade 4 located at the liquid level rotates, the guide blade 4 pushes the light debris floating on the liquid surface to move in the direction of rotation on the water surface. When the light plant debris is pushed to the area of ​​the arc-shaped guide plate frame 52, Liquid surface debris flows smoothly through the opening 51 and into the interior of the soaking sleeve 5 along the water flow of the guide channel 521, realizing the smooth collection of light debris. Then, as the rotating shaft 3 continues to rotate, the support rod 34 on the sliding sleeve 31 drives the action protrusion 35 to rotate to the ball 546 at the top of the connecting shaft 541. The ball 546 first contacts the inclined action area 351 on the action protrusion 35. As the support rod 34 continues to rotate, the planar action area 352 moves smoothly to above the ball 546. The planar action area 352 presses the ball 546 downward, thereby driving the connecting shaft 541 to slide downward on the support plate 55. The connecting shaft 541 pushes the pressure plate 54 to descend as a whole. During this descent, the spring part 57 between the top of the connecting shaft 541 and the support plate 55 is in a compressed and energy-storing state.

[0024] During its descent, the pressure plate 54 first drives the baffle 542, which is slidably fitted to it, to move downwards synchronously. When the pressure plate 54 descends to a height close to the liquid surface opening 51, the baffle 542 moves to the opening 51 and completely covers the area, thus physically sealing the liquid inlet area of ​​the soaking sleeve 5. After sealing, the pressure plate 54 needs to continue to descend deeper into the liquid surface. At this time, because the baffle 542 is limited by the opening 51 and stops moving, the spring body 545 connecting the support 543 and the top of the pressure plate 54 is stretched. During the subsequent descent of the pressure plate 54, the baffle 542 remains at the opening. Since the area of ​​the soaking sleeve 5 below the intercepting plate 53 has been... With the filter holes 56 pre-set, after the baffle 542 blocks the opening 51, as the pressure plate 54 continues to slowly descend within the liquid surface, the liquid and light debris inside the soaking sleeve 5 are forced to flow downwards. The light debris, along with the water flow, enters the area below the intercepting plate 53 through the inlet end of the intercepting plate 53. During this process, the liquid solvent seeps out of the soaking sleeve 5 through the filter holes 56, while light debris with a particle size larger than the aperture of the filter holes 56 is physically intercepted on the surface of the filter holes 56 below the intercepting plate 53. Since the outlet aperture of the intercepting plate 53 is smaller than the inlet aperture, this constriction design can effectively prevent the light debris located below the intercepting plate 53 from floating back upwards due to buoyancy.

[0025] During the continuous descent of the pressure plate 54, when the bottom of the pressure plate 54 contacts the top of the force-bearing shaft 501, the pressure plate 54 only touches the force-bearing shaft 501 and does not apply a force sufficient to overcome the constant force spring 50. Therefore, the closed plate frame 58 remains in place, and the light debris in the soaking sleeve 5 remains in a static soaking state below the intercepting plate 53. At the end of the extraction, it is necessary to discharge the light debris collected in the soaking sleeve 5. At this time, the electromagnet 361 is energized to generate a magnetic force that repels the magnetic shaft 311. The magnetic force pushes the sliding sleeve 31 to slide downward and compresses the return spring 33. The sliding sleeve 31 drives the support rod 34 and its action protrusion 35 to move downward synchronously. At this time, the planar action area 352 of the action protrusion 35 continues to apply force to the ball 546, pushing the pressure plate 54 down to the position where it is in contact with the surface of the intercepting plate 53. During the descent, the pressure plate 54 directly contacts and applies a downward pushing force to the force-bearing shaft 501. After being compressed, the force-bearing shaft 501 drives the closed plate frame 58 to move downward. During the downward movement, the closed plate frame 58 drives the limiting shaft 581 to slide within the positioning sleeve 59 and compress the constant force spring 50. The closed plate frame 58 disengages from the bottom of the soaking sleeve 5, and a smooth discharge channel is formed at the bottom of the soaking sleeve 5.

[0026] After the material discharge is completed, the power supply to the electromagnet 361 is disconnected, the repulsive force of the electromagnet 361 disappears, the sliding sleeve 31 slides upward and returns to its initial position under the elastic force of the return spring 33, the action protrusion 35 moves away from the ball 546, the pressure plate 54 resets upward under the action of the spring part 57, and the force-bearing shaft 501, under the action of the constant force spring 50, carries the sealing plate frame 58 back up and fits tightly against the bottom of the soaking sleeve 5, realizing the re-closure of the bottom opening, ready to welcome the next round of extraction operation.

[0027] During the normal rotation of the shaft 3, the support sleeve 8 drives multiple connecting sleeves 81 to rotate synchronously. The movable sleeve 85 inside the connecting sleeve 81 slides towards the steel shaft 82 under the action of centrifugal force. During the movement of the movable sleeve 85, the spring mechanism 86 is stretched. At the same time, the arc-shaped groove 851 on the inner wall of the movable sleeve 85 applies a driving force to the steel ball 821 at the end of the steel shaft 82, causing the steel shaft 82 to rotate. The rotation of the steel shaft 82 drives the arc-shaped concave blade 83 fixed to it to rotate to a specific angle of material reception. At this time, the lifting plate 6 close to the bottom of the tank 1 lifts up the heavy plant debris deposited at the bottom of the tank during the rotation. The heavy plant debris flows into the arc-shaped concave surface of the arc-shaped concave blade 83 with the water flow and enters the tapered silica gel channel 84 through the through hole 831. The tapered silica gel channel 84 has a wide inlet and a narrow outlet, which physically squeezes the lifted heavy plant debris. The compressed debris is squeezed out.

[0028] Because plant fiber debris is prone to tangling and getting stuck when passing through the tapered silicone channel 84, the servo motor 21 can be controlled to rotate multiple times in the set direction and then reverse once. This uses the liquid flow to physically loosen the plant debris that is temporarily stuck inside the tapered silicone channel 84. Afterward, the servo motor 21 resumes normal forward rotation. Through the alternating forward and reverse rotation, the continuous and smooth operation of the heavy plant debris extrusion process can be effectively ensured.

[0029] An extraction process for an ultrafine cashmere dyeing extraction device specifically includes the following steps: S1. Plant debris and extraction solvent are added into tank 1 to the preset liquid level. Servo motor 21 is started. Servo motor 21 drives shaft 3 to rotate. Shaft 3 drives guide blade 4, stirring blade 7, lifting plate 6, support sleeve 8, connecting sleeve 81 and arc-shaped concave blade 83 to rotate synchronously. S2. The guide blade 4 pushes the light debris floating on the liquid surface into the soaking sleeve 5 through the guide channel 521 formed between the arc-shaped guide plate frame 52. The sliding sleeve 31 rotates with the rotating shaft 3 and drives the action protrusion 35. The action protrusion 35 acts on the ball 546. The connecting shaft 541 drives the pressure plate 54 to descend. The pressure plate 54 first drives the baffle 542 to block the opening 51, and then continues to descend to approach the interception plate 53. The liquid is drained through the filter hole 56 and the light debris is intercepted below the interception plate 53. S3. After extraction, the electromagnet 361 is energized and generates a repulsive force on the magnetic shaft 311. The magnetic shaft 311 pushes the sliding sleeve 31 down and compresses the return spring 33. The sliding sleeve 31 lowers the pressure plate 54 to fit against the interception plate 53 through the action protrusion 35. The pressure plate 54 pushes the force-bearing shaft 501 and drives the closed plate frame 58 down. The bottom of the soaking sleeve 5 opens to allow light debris and residual liquid to be discharged. S4. The rotating shaft 3 drives the connecting sleeve 81 to rotate synchronously. The moving sleeve 85 slides along the inner wall of the connecting sleeve 81 under centrifugal force and stretches the spring mechanism 86. The arc-shaped groove 851 on the inner wall of the moving sleeve 85 applies force to the steel ball 821, thereby causing the steel shaft 82 to rotate and the arc-shaped concave blade 83 to adjust the angle of the material. The lifting plate 6 lifts up the heavy debris deposited at the bottom. The heavy debris enters the tapering silicone flow channel 84 through the through hole 831 and is squeezed out. The rotating shaft 3 rotates intermittently in the opposite direction to avoid blockage in the tapering silicone flow channel 84. S5. When the electromagnet 361 is de-energized, the sliding sleeve 31 rises and resets under the action of the reset spring 33, the pressure plate 54 rises and resets under the action of the spring part 57, and the force-bearing shaft 501 drives the closing plate frame 58 to rise and reset under the action of the constant force spring 50 and re-closes the bottom of the soaking sleeve 5. S6. Repeat S2 to S5 to achieve continuous extraction. After extraction is completed, rinse the soaking sleeve 5 and the closed plate rack 58 to remove residual debris.
