Description

Technical Field

[0001] This invention relates to the field of edible fungi product production equipment, specifically to an edible fungi selenium protein extraction device and extraction method. Background Technology

[0002] Edible fungal selenoproteins are widely used in the food and pharmaceutical fields due to their antioxidant and immunomodulatory functions. The extraction process of edible fungal selenoproteins involves multiple steps, including cell disruption, extraction, separation and purification, concentration and drying. The extraction mixing process involves placing the disrupted fungi into the extraction solution and stirring to dissolve the selenoproteins in the solvent. After solid-liquid separation, the selenoproteins in the liquid are purified. This extraction mixing step is the core process of selenoprotein extraction, encompassing numerous tasks such as raw material homogenization, extraction solution filtration and separation, and waste residue post-treatment. This step directly determines the selenoprotein yield.

[0003] Specifically, after the edible fungi are crushed, the bottom of the tank in existing extraction devices is mostly inclined to facilitate material discharge. However, ordinary stirring components with straight rod-type paddle blades are difficult to fit against the inclined bottom of the tank, easily forming a dead angle on the inclined side, resulting in the sediment being unable to be effectively stirred. Moreover, existing equipment only achieves solid-liquid separation through centrifugation, plate and frame filtration, etc., but a large amount of selenium protein extract remains in the waste residue and is not effectively obtained. If static filtration is carried out using structures such as filter screens and filter cloths, the waste residue will easily clog the filter pores, making continuous operation impossible. Furthermore, the structure of the separated solid fungal residue is loose, resulting in high subsequent collection and transportation costs. Summary of the Invention

[0004] The purpose of this invention is to provide an edible fungus selenium protein extraction device and method to solve the above-mentioned problems. Through the positioning wheel, torsion spring, and rotating lug hinge structure of the stirring rod, the stirring rod elastically adheres to the inclined tank bottom and self-adaptively swings. Combined with the arc-shaped oscillating plate, it drives the material to tumble up and down, eliminating sediment dead zones and promoting contact between the residue and the extractant, thus improving the uniformity of selenium protein dissolution. The staggered holes of the fixed and movable spirals form a spiral filtration channel. While rotating and conveying the waste residue, simultaneous compression and percolation are performed to improve residual liquid recovery. Simultaneously, the transmission frame reuses the spindle power via a synchronous belt and half-gears, eliminating the need for an additional compression motor. The intermittent meshing of the half-gears and the spring's energy storage complete the conveying and compression of the waste residue, facilitating subsequent resource recovery of the waste residue, as detailed below.

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

[0012] Preferably, a retaining cylinder is provided on the bottom side of the transmission frame and fixed to the top side of the compression tube. A secondary shaft is rotatably arranged inside the retaining cylinder. The secondary shaft is parallel to the mandrel. A drive pulley is fixed to the outer end of the mandrel, and a transmission pulley is fixed to the outer end of the secondary shaft.

The support rod is clearance-fitted with the tail cover. A return spring is sleeved on the outside of the support rod between the inner baffle and the tail cover. A sealing cap that fits against the inner wall of the compression pipe is fixed on the side of the inner baffle away from the outer baffle. The sealing cap is used to seal the bottom end of the waste residue pipe.

[0015] Preferably, a lid is fixed to the top of the tank, and a feed inlet with a flip-top structure is provided on the lid. The lid also has a mounting hole for accommodating the feed inlet. A stirring assembly is provided inside the tank, which includes a stirring motor fixed to the top side of the lid. A stirring shaft extending into the tank is fixed to the output end of the stirring motor. A synchronizing ring is fixed to the bottom end of the stirring shaft. Multiple sets of rotating ears are arranged around the outer circumference of the synchronizing ring, and stirring rods are provided on the outer side of each set of rotating ears. A receiving groove for an internal end shaft is provided at the end of the stirring rod. The end shaft is hinged to the rotating ears. A torsion spring is provided on the outer side of the end shaft to keep the stirring rod pressed downward. A positioning wheel is rotatably provided at the outer end of the stirring rod. Multiple spokes are arranged on the outer circumference of the stirring shaft. Multiple arc-shaped oscillating plates are evenly arranged along the length of the top side of the stirring rod.

[0016] The extraction method of the edible fungus selenium protein extraction device includes the following steps:

[0017] a. When crushing and purifying edible fungi to extract selenoprotein, the material that needs to be precipitated to complete solid-liquid separation is poured into the tank through the feeding port. The stirring motor is turned on to drive the stirring shaft to rotate. The bottom ring of the stirring shaft supports the rotation of multiple stirring rods and multiple spokes above. The torsion spring keeps the positioning wheel at the outer end of the stirring shaft pressed against the bottom of the tank, ensuring that the material gathered at the bottom of the inclined tank can be stirred evenly. The material is turned up and down by the arc-shaped oscillating blades following the rotation of the stirring rods, thus promoting the separation of the extraction mixture from the solid waste.

[0018] b. After mixing, open the valve and use the discharge pump to guide the solid-liquid mixture into the conveying cylinder along the bottom pipe, guide pipe and feed pipe. The filter pipe at the bottom of the conveying cylinder will discharge the extracted mixture to the next processing step. At the same time, the drive unit drives the mandrel to rotate, and the mandrel drives the fixed screw and the movable screw to rotate synchronously. The fixed screw and the movable screw form a spiral plate, thereby forming an auger conveying mechanism in the conveying cylinder to compress and convey the solid waste towards the waste residue pipe.

[0019] c. During the upward conveying of waste residue, the two sets of screws exert a squeezing effect on the waste residue. The staggered channels on the two sets of screws serve as a screw filtration channel. The extracted mixture discharged by the squeezing flows downward into the filtrate pipe along the screw filtration channel, thereby collecting and merging the extracted mixture remaining in the solid waste.

[0020] d. After the liquid material in the tank is discharged and the residual extraction mixture in the solid waste is collected, the electromagnet between the end cap and the outer ring of the control unit is energized to attract the outer ring, which drives the inner ring to support the movable spiral so that it is pressed against the outside of the fixed spiral. At this time, the fixed hole and the movable hole are alternately closed to close the spiral filtration channel. At this time, the spindle drives the two sets of spiral plates in a pressed state as an integrated auger mechanism to quickly transport the solid waste to the direction of the waste residue pipe above.

[0021] e. Solid waste is conveyed downward into the waste slag pipe. While the spindle rotates, the secondary shaft is driven to rotate synchronously through the synchronous belt. The half gear at the end of the secondary shaft meshes with the tooth groove on the top side of the cover to store energy during the rotation of the half gear driven by the secondary shaft. At the same time, the outer baffle and the inner baffle are synchronously drawn into the compression pipe. A waste slag compression cavity is formed between the outer baffle and the inner baffle. Solid waste is sent into the compression pipe between the inner baffle and the outer baffle through the waste slag pipe. The half gear meshes with the tooth groove to compress the return spring and store energy.

[0022] f. When the half gear rotates to the position where it is separated from the tooth groove, the pressure of the inner baffle on the return spring is released. At this time, the return spring pushes the inner baffle to push the solid waste in the compression chamber out of the outer port of the compression tube, so as to achieve solid-liquid separation and compression of solid waste at the same time.

[0023] The beneficial effects are as follows: 1. The present invention uses a positioning wheel at the end of the stirring rod in conjunction with a torsion spring structure to ensure that the stirring rod always elastically presses against the inclined tank bottom. During the rotation and stirring process, it adapts to the inclined shape of the tank bottom. By using the rotating lug hinge structure of the synchronous ring, the stirring rod is kept to swing adaptively with the tilt of the tank bottom, thereby eliminating the dead corner of material deposition at the inclined tank bottom and ensuring that the material in the tank is stirred in the whole area. At the same time, the arc-shaped swing plate on the top side of the stirring rod rotates with the stirring and uses the upward and downward motion trajectory of the arc-shaped curved surface to drive the material to circulate up and down, rather than a single horizontal shearing and stirring, so that the edible fungus residue and the extractant can fully contact each other, improving the dissolution efficiency and uniformity of selenoprotein.

[0024] 2. The fixed holes of the fixed spiral and the movable holes of the movable spiral are interwoven to form a spiral filtration channel. When the spiral rotates and transports the waste residue, it forms a spiral squeezing and permeation action on the waste residue. Compared with traditional static filtration, the recovery of residual liquid is improved, thereby avoiding the waste of selenium protein.

[0025] 3. Furthermore, the control unit can drive the movable spiral to slide along the mandrel. During filtration, the movable spiral separates from the fixed spiral, and the channels are connected, realizing simultaneous conveying and extrusion filtration. When rapid slag discharge is required, the movable spiral is pressed against the fixed spiral, the filtration channels are closed, and an integrated auger is formed for rapid slag discharge.

[0026] 4. The transmission frame uses a synchronous belt and half gears for transmission, which synchronously transmits the rotational power of the spindle to the waste slag compression unit. No additional compression power source is required, reducing system energy consumption. At the same time, the half gears intermittently mesh with the cover, while the compression and reset springs store energy, and then instantly push the waste slag, so that the waste slag completes the alternating and continuous action of slag discharge and compression in the compression tube, and the waste slag is discharged after compression, which is convenient for subsequent collection and resource utilization.

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0045] See Figures 1-14 As shown, the present invention provides an edible fungus selenium protein extraction device, including a tank body 1, a tank bottom 2 and a bottom pipe 3. The tank bottom 2 is located at the bottom of the tank body 1 and forms a cylindrical structure with the tank body 1. One side of the tank bottom 2 is inclined downward to guide the material to gather towards the bottom pipe 3, thereby improving the thoroughness of discharge. The bottom pipe 3 is connected to the downward side of the tank bottom 2. A guide pipe 6 is connected to the outside of the bottom pipe 3. A discharge pump 4 is provided between the guide pipe 6 and the bottom pipe 3. A conveying cylinder 7 is connected to the outside of the guide pipe 6 to receive the solid-liquid mixture and realize solid-liquid separation and waste residue conveying through a spiral structure.

[0046] The rear end of the conveying cylinder 7 extends upward at an angle, and a feed pipe 701 connected to the guide pipe 6 is provided on the top side of the bottom end of the conveying cylinder 7 to guide the solid-liquid mixture conveyed by the guide pipe 6 into the interior of the conveying cylinder 7. A filter pipe 702 is connected to the bottom side of the conveying cylinder 7 below the feed pipe 701 to collect the selenoprotein extract after spiral filtration and convey it to the next process. A mandrel 703 is rotatably mounted inside the conveying cylinder 7. A fixed spiral 704 and a movable spiral 705 are provided on the outer side of the mandrel 703, extending spirally and parallel to each other. The fixed spiral 704 is fixedly connected to the mandrel 703, and the movable spiral 705 can slide along the length of the mandrel 703. The movable spiral 705 and the spindle 703 do not rotate relative to each other, ensuring that the spindle 703 can drive the movable spiral 705 to rotate synchronously. The fixed spiral 704 is densely covered with fixed holes 704a, and the movable spiral 705 is densely covered with movable holes 705a that are staggered with the fixed holes 704a. The fixed holes 704a and the movable holes 705a form a spiral filtration channel, which is used to squeeze out the residual extract through the channel during the spiral conveying of waste residue, so as to achieve secondary recovery. The end of the conveying cylinder 7 is provided with a control part 8 to support the sliding of the movable spiral 705. When the fixed spiral 704 and the movable spiral 705 are in close contact, the spiral filtration channel is closed.

[0047] As an optional implementation, the movable screw 705 is fixed with an adjusting ring 705b sleeved on the outside of the spindle 703 at one end near the control unit 8. The control unit 8 includes a connecting cylinder 801 fixed to the end of the feed cylinder 7. An end cover 802 is fixed inside the connecting cylinder 801. An inner ring 803 and an outer ring 804 are respectively provided on both sides of the end cover 802. A slide rod 805 is fixed between the inner ring 803 and the outer ring 804, passing through the end cover 802. The slide rod 805 is in clearance fit with the end cover 802 to support the inner ring 803 and the outer ring 804 to slide synchronously and smoothly on both sides of the end cover 802. With this configuration, the movable screw 705 can be smoothly moved closer to or away from the fixed screw 704 by the slide rod 805 sliding and guiding along the axial direction of the end cover 802.

[0048] A support spring 805a is sleeved on the outer side of the slide rod 805 inside the outer ring 804. The support spring 805a is used to press the outer ring 804 outward to ensure that the support spring 805a can push the outer ring 804 to pull the inner ring 803 by the slide rod 805. A support spindle 703 is fixed on the outer side of the end cover 802 and a sealing ring 806 that passes through the control part 8. The inner ring 803 and the adjusting ring 705b are rotated and engaged by a bearing. The support spring 805a keeps the inner ring 803 against the adjusting ring 705b outward. The screw is tightened to keep the movable screw 705 and the fixed screw 704 separated. An adjustment ring 705b and an electromagnet for controlling the sliding of the movable screw 705 are provided between the outer ring 804 and the end cover 802. With this configuration, the outer ring 804 can be attracted by the electromagnet when energized, compressing the support spring 805a and causing the movable screw 705 to press against the fixed screw 704. When the power is turned off, the support spring 805a resets and pushes the movable screw 705 to separate, realizing a rapid switching between the filtration and slag discharge processes.

[0049] The bottom end of the feeding cylinder 7 is provided with a drive unit 13 that supports the rotation of the spindle 703. The drive unit 13 is a motor with a reducer. The top end of the filtrate tube 702 is flush with the inner wall of the feeding cylinder 7, and the top end of the filtrate tube 702 is provided with a tube port filter screen 702a to intercept waste particles and prevent the filtrate tube 702 from being blocked. The tube port filter screen 702a is connected to the spiral filtration channel. This arrangement ensures that all the extract seeping out of the spiral filtration channel flows into the filtrate tube 702, thereby improving the collection efficiency.

[0050] The top and bottom of the conveying cylinder 7 are connected to a downward-extending waste residue pipe 11. The bottom of the waste residue pipe 11 is connected to a horizontally extending compression pipe 12. The rear end of the compression pipe 12 is sealed with a tail cap 16. A transmission frame 15 extending above the compression pipe 12 is fixed on the outside of the control unit 8. This arrangement allows the waste residue separated from the conveying cylinder 7 to fall into the compression pipe 12 through the waste residue pipe 11, achieving seamless connection between the conveying and compression processes.

[0051] A retaining cylinder 15a is fixed to the top side of the compression tube 12 on the bottom side of the transmission frame 15. A secondary shaft 15b is rotatably arranged inside the retaining cylinder 15a. The secondary shaft 15b is parallel to the spindle 703. A drive pulley 703a is fixed to the outer end of the spindle 703. A transmission pulley 15c is fixed to the outer end of the secondary shaft 15b. A synchronous belt 15d is connected between the drive pulley 703a and the transmission pulley 15c to transmit the rotational power of the spindle 703 to the secondary shaft 15b, thereby realizing the power connection between the compression unit and the conveying unit.

[0052] A through groove runs vertically through the top side of the rear end of the compression tube 12. The secondary shaft 15b extends to one end of the top side of the compression tube 12 and is fixed with a half gear 15e. The half gear 15e extends into the interior of the compression tube 12 along the through groove. In this way, the half gear 15e can mesh with the tooth groove 12d on the top side of the cover 12c, driving the cover 12c to move the inner and outer baffles 12a along the axial direction of the compression tube 12.

[0053] The compression tube 12 is provided with parallel outer baffles 12a and inner baffles 12b. A support rod 12e is fixed between the outer baffles 12a and the inner baffles 12b, which passes through the tail cover 16. The support rod 12e is fitted with the tail cover 16 with a clearance, thereby ensuring that the inner and outer baffles 12a slide smoothly along the axial direction of the compression tube 12. A return spring 12f is sleeved on the outside of the support rod 12e between the inner baffles 12b and the tail cover 16. A cap 12c is fixed on the side of the inner baffles 12b away from the outer baffles 12a, which fits against the inner wall of the compression tube 12. The cap 12c is used to seal the bottom end of the waste residue tube 11.

[0054] A tank cover 101 is fixed to the top of the tank body 1. A feed inlet 10 with an openable flip-top structure is provided on the top of the tank cover 101, and a mounting hole 102 for accommodating the feed inlet 10 is provided on the tank cover 101. An observation ladder 14 for standing personnel is provided on the outside of the tank body 1. An agitator 9 is provided inside the tank body 1. The agitator 9 includes an agitator motor 901 fixed to the top side of the tank cover 101. A motor base 103 supporting the agitator motor 901 is provided on the top of the tank cover 101. An agitator shaft 902 extending into the tank body 1 is fixed to the output end of the agitator motor 901. A synchronization ring 904 is fixed to the bottom end of the agitator shaft 902. Multiple sets of rotating ears 904a are fixedly arranged around the outer circumference of the synchronization ring 904, and each set of rotating ears 904a has a... The device includes a stirring rod 905, with a receiving groove 906 at the end of the stirring rod 905 containing a built-in end shaft 907. The end shaft 907 is hinged to a rotating lug 904a. A torsion spring 907a is provided on the outside of the end shaft 907 to keep the stirring rod 905 pressed downwards. This ensures that the positioning wheel 909 always fits against the inner surface of the tank bottom 2 through continuous elastic force, adapting to changes in the tilt angle of the tank bottom 2. The positioning wheel 909 is rotatably provided at the outer end of the stirring rod 905. Multiple spokes 903 are provided on the outer circumference of the stirring shaft 902. Multiple arc-shaped oscillating plates 908 are evenly provided on the top side of the stirring rod 905 along its length. The oscillating plates 908 rotate with the stirring rod 905 to create up-and-down turbulence, causing the bottom material to surge upwards and improving the uniformity of solid-liquid mixing.

[0055] The extraction method of edible fungus selenium protein extraction device includes the following steps:

[0056] a. When edible fungi are crushed and purified to extract selenoprotein, the material that needs to be precipitated to complete solid-liquid separation is poured into tank 1 through feeding port 10. The stirring motor 901 is turned on to drive the stirring shaft 902 to rotate. The bottom ring 904 of the stirring shaft 902 supports the rotation of multiple sets of stirring rods 905 and multiple spokes 903 above. The torsion spring 907a keeps the positioning wheel 909 at the outer end of the stirring shaft 902 pressed against the bottom surface of the tank bottom 2, ensuring that the material gathered at the inclined tank bottom 2 can be stirred evenly. The arc-shaped oscillating plate 908 follows the rotation of the stirring rod 905, and the oscillating plate 908 turns the material up and down to promote the separation of the extraction mixture and solid waste.

[0057] b. After mixing, open valve 5 and use discharge pump 4 to guide the solid-liquid mixture into conveying cylinder 7 through bottom pipe 3, guide pipe 6 and feed pipe 701. The filter pipe 702 at the bottom of conveying cylinder 7 will discharge the extracted mixture to the next processing step. At the same time, drive unit 13 drives spindle 703 to rotate. Spindle 703 drives fixed screw 704 and movable screw 705 to rotate synchronously. The fixed screw 704 and movable screw 705 form a spiral plate, thereby forming auger conveying mechanism in conveying cylinder 7 to compress and convey solid waste towards waste slag pipe 11.

[0058] c. During the upward conveying of waste residue, the two sets of screws exert a squeezing effect on the waste residue. The staggered channels on the two sets of screws serve as a screw filtration channel. The extracted mixture discharged by the squeezing flows downward into the filtrate pipe 702 along the screw filtration channel, thereby collecting and merging the extracted mixture remaining in the solid waste.

[0059] d. After the liquid material in tank 1 is discharged and the residual extraction mixture in the solid waste is collected, the electromagnet between the end cap 802 and the outer ring 804 of the control unit 8 is energized and attracted to pull the outer ring 804 to drive the inner ring 803 to support the movable spiral 705 so that it is pressed against the outside of the fixed spiral 704. At this time, the fixed hole 704a and the movable hole 705a are alternately closed to close the spiral filter channel. At this time, the spindle 703 drives the two sets of tightly pressed spiral plates as an integrated auger mechanism to quickly transport the solid waste to the direction of the upper waste pipe 11.

[0060] e. Solid waste is conveyed downward into the waste slag pipe 11. While the spindle 703 rotates, the secondary shaft 15b is driven to rotate synchronously through the synchronous belt 15d. The half gear 15e at the end of the secondary shaft 15b meshes with the tooth groove 12d on the top side of the cover 12c to store energy during the rotation of the half gear 15e driven by the secondary shaft 15b. At the same time, the outer baffle 12a and the inner baffle 12b are synchronously drawn into the compression pipe 12, forming a waste slag compression cavity between the outer baffle 12a and the inner baffle 12b. Solid waste is sent into the compression pipe 12 between the inner baffle 12b and the outer baffle 12a through the waste slag pipe 11. The half gear 15e meshes with the tooth groove 12d to compress the return spring 12f to store energy.

[0061] f. When the half gear 15e rotates to the position where it is separated from the tooth groove 12d, the pressure of the inner baffle 12b on the return spring 12f is released. At this time, the return spring 12f pushes the inner baffle 12b to push the solid waste in the compression chamber out from the outer port of the compression tube 12, so as to achieve solid-liquid separation and compression of solid waste at the same time.

[0062] The positioning wheel 909 at the end of the stirring rod 905, in conjunction with the torsion spring 907a, ensures that the stirring rod 905 is always elastically pressed against the inclined tank bottom 2. During the rotation and stirring process, it adapts to the inclined shape of the tank bottom 2. Utilizing the hinge structure of the rotating lug 904a of the synchronization ring 904, the stirring rod 905 is kept to swing adaptively with the inclination of the tank bottom 2, thereby eliminating the dead corners of material deposition in the inclined tank bottom 2 and ensuring that the material inside the tank is stirred in the entire area. At the same time, when the arc-shaped oscillating plate 908 on the top side of the stirring rod 905 rotates with the stirring, it uses the upward and downward scooping motion trajectory of the arc-shaped curved surface to drive the material to circulate and tumble up and down, rather than simply horizontal shearing and stirring. This allows the edible fungus residue to fully contact the extractant, improving the dissolution efficiency and uniformity of selenoprotein.

[0063] The fixed hole 704a of the fixed spiral 704 and the movable hole 705a of the movable spiral 705 are interwoven to form a spiral filtration channel. When the spiral rotates and transports the waste residue, it forms a spiral extrusion filtration action on the waste residue. Compared with traditional static filtration, the residual liquid recovery is improved, thereby avoiding the waste of selenium protein.

[0064] Furthermore, the control unit 8 can drive the movable spiral 705 to slide along the spindle 703. During filtration, the movable spiral 705 separates from the fixed spiral 704, and the channels are connected, so that conveying and extrusion filtration can be carried out simultaneously. When rapid slag discharge is required, the movable spiral 705 is pressed against the fixed spiral 704, the filtration channels are closed, and an integrated auger is formed to quickly discharge slag.

[0065] The transmission frame 15 transmits the rotational power of the spindle 703 to the waste slag compression unit through the synchronous belt 15d and the half gear 15e. This eliminates the need for an additional compression power source and reduces system energy consumption. At the same time, the half gear 15e intermittently meshes with the cover 12c, while simultaneously compressing the return spring 12f to store energy. Then, it instantly pushes the waste slag, causing the waste slag to complete the alternating continuous action of slag discharge and compression in the compression tube 12. The waste slag is then discharged after compression, facilitating subsequent collection and resource utilization.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.

When extracting selenoprotein by crushing and purifying edible fungi, the material that needs to be precipitated to complete solid-liquid separation is poured into the tank (1) through the feeding port (10). The stirring motor (901) is turned on to drive the stirring shaft (902) to rotate. The stirring shaft (902) is supported by the synchronous ring (904) at the bottom of the stirring shaft (902) to rotate multiple sets of stirring rods (905) and multiple spokes (903) above. The positioning wheel (909) at the outer end of the stirring shaft (902) is always kept pressed against the bottom surface of the tank bottom (2) by the torsion spring (907a) to ensure that the material gathered at the bottom of the tank (2) in the inclined state can be stirred evenly. The material is then turned upside down by the arc-shaped oscillating plate (908) following the rotation of the stirring rod (905). The oscillating plate (908) is used to turn the material up and down to promote the separation of the extraction mixture and solid waste. b. After stirring, open valve (5) and use discharge pump (4) to feed the solid-liquid mixture into conveying cylinder (7) along bottom pipe (3), guide pipe (6) and feed pipe (701). The filter pipe (702) at the bottom of conveying cylinder (7) will discharge the extracted mixture to the next processing step. At the same time, the drive unit (13) drives the spindle (703) to rotate. The spindle (703) drives the fixed screw (704) and movable screw (705) to rotate synchronously. The fixed screw (704) and movable screw (705) form a spiral plate, thereby forming a screw conveyor mechanism in conveying cylinder (7) to compress and transport solid waste towards waste pipe (11). c. During the upward conveying of waste residue, the two sets of screws exert a squeezing effect on the waste residue. The extraction mixture discharged by the squeezing flows downward into the filtrate pipe (702) through the staggered channels on the two sets of screws as a screw filtration channel, thereby collecting and merging the extraction mixture remaining in the solid waste. d. After the liquid material in the tank (1) is discharged and the residual extraction mixture in the solid waste is collected, the electromagnet between the end cap (802) of the control unit (8) and the outer ring (804) is energized and attracted to pull the outer ring (804) to drive the inner ring (803) to support the movable spiral (705) so that it is close to the outside of the fixed spiral (704). At this time, the fixed hole (704a) and the movable hole (705a) are alternately closed to close the spiral filter channel. At this time, the spindle (703) drives the two sets of spiral plates in close contact as an integrated auger mechanism to quickly transport the solid waste to the direction of the upper waste pipe (11). e. Solid waste is conveyed downward into the waste slag pipe (11). While the spindle (703) rotates, the secondary shaft (15b) is driven to rotate synchronously through the synchronous belt (15d). The half gear (15e) at the end of the secondary shaft (15b) meshes with the tooth groove (12d) on the top side of the cover (12c) to store energy during the rotation of the half gear (15e) driven by the secondary shaft (15b). At the same time, the outer baffle (12a) and the inner baffle (12b) are synchronously drawn into the compression pipe (12). A waste slag compression cavity is formed between the outer baffle (12a) and the inner baffle (12b). Solid waste is sent into the compression pipe (12) between the inner baffle (12b) and the outer baffle (12a) through the waste slag pipe (11). The half gear (15e) meshes with the tooth groove (12d) to compress the return spring (12f) to store energy. f. When the half gear (15e) rotates to the position where it is separated from the tooth groove (12d), the pressure of the inner baffle (12b) on the return spring (12f) is released. At this time, the return spring (12f) pushes the inner baffle (12b) to push the solid waste in the compression chamber out from the outer port of the compression tube (12), so as to achieve solid-liquid separation and compression of solid waste at the same time.
