Description

Technical Field

[0001] This invention relates to the field of cottonseed meal processing technology, specifically to a novel extractor for cottonseed meal processing. Background Technology

[0002] Cottonseed meal processing refers to the process of producing cottonseed meal (or cottonseed meal for short) that meets feed, fertilizer, or industrial application standards by using cottonseed cake, a byproduct of cottonseed oil extraction, as raw material, through a series of physical or chemical processes such as dehulling, crushing, detoxification, and grading. Cottonseed meal is rich in protein (crude protein content of about 35% to 45%) and is an important feed protein raw material. However, cottonseed naturally contains gossypol (a toxic substance that can affect the animal reproductive system and damage the liver), so detoxification is the core step in cottonseed meal processing.

[0003] The existing technology still has the following problems: 1. In the existing technology, when leaching cottonseed meal particles, due to the difference in particle size within the cottonseed meal particle pile, small-volume cottonseed meal particles are easily entrained by the solvent and enter the mixed oil collection system during the leaching process, causing entrainment problems; large-volume cottonseed meal particles are prone to forming gaps, causing the solvent to flow quickly through the gaps and forming channeling channels, which prevents the solvent from fully contacting the particles, resulting in insufficient leaching in some areas, ultimately leading to a high overall residual oil rate, reducing leaching efficiency and resource utilization; 2. In existing technologies, leaching equipment often uses high-pressure direct spraying to transport industrial-grade n-hexane. Excessive spraying pressure directly impacts the cottonseed meal particle pile, causing localized depressions and erosion grooves on the surface of the cottonseed meal pile. This not only damages the structure of the cottonseed meal pile but also crushes some cottonseed meal particles, generating a large amount of fine powder, further aggravating the entrainment problem. At the same time, high-pressure spraying easily causes solvent atomization and splashing, which leads to increased solvent consumption and production costs. In addition, traditional spraying methods cannot be dynamically adjusted according to the state of the cottonseed meal particles, which easily leads to uneven solvent distribution, affecting the leaching effect and cottonseed meal quality.

[0004] To address this, a novel extractor for cottonseed meal processing is proposed. Summary of the Invention

The size of the nylon cloth combined with the mounting plate is adapted to the size of the loading groove between two adjacent baffles.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. Through the synergistic action of the screening and vibration components in the separation mechanism, cottonseed meal particles are accurately graded according to their size. In addition, the screening trough plate, combined with the vibration structure driven by dual servo rotary motors, can efficiently separate large and small cottonseed meal particles, which are then conveyed to the conveyor belt of the leaching mechanism through corresponding discharge trough plates. This allows the graded cottonseed meal particles to be processed in independent leaching channels, avoiding the problems of small particles being easily entrained by solvent and forming entrainment, and large particles easily forming gaps that cause channeling, which are common during mixed leaching. At the same time, through the combination structure of the mounting plate and nylon cloth in the leaching component, the elastic pressure of spring 2 compacts the material layer, eliminating the porous channels in the material layer and avoiding particle breakage caused by rigid contact, further blocking the generation of channeling and entrainment, and ensuring the stability of the leaching process. 2. Different concentrations of industrial-grade n-hexane can be introduced through the connection ports on the upper and lower sides of the leaching rack. Large-volume particles correspond to high-concentration solvents and longer leaching times, while small-volume particles correspond to low-concentration solvents and shorter leaching times. This ensures that both types of particles are in the optimal extraction state, and the overall residual oil rate can be reduced compared to mixed leaching. On the other hand, the nylon cloth adopts an immersion-type solvent delivery method, which avoids the problem of local depressions and scouring grooves on the surface of the material layer caused by the impact of high-pressure spray on the particles, thus forming channel channels. This ensures the leaching effect of cottonseed meal particles. In addition, the second scraper quantitatively scrapes the cottonseed meal particles in the baffle to ensure uniform material layer thickness, further improving the leaching uniformity and cottonseed meal protein activity. 3. Through the electrical linkage of the position monitoring controller, drive motor, and drive telescopic rod, the entire process of cottonseed meal particle conveying, grading, and leaching is automated: the position monitoring controller accurately identifies the particle position and automatically triggers the operation of the leaching component and the sealing or opening of the discharge trough plate, reducing manual intervention; the detachable guide plate and gauze facilitate cleaning and maintenance, and scraper plate one and scraper plate two can respectively clean the inner wall of the processing tank and the baffle plate of residual particles, reducing the probability of equipment blockage; at the same time, the solvent is impregnated and penetrated through the nylon cloth, reducing solvent splashing and atomization caused by high-pressure spraying, reducing the concentration of solvent vapor in the workshop, which not only meets the safety use regulations for flammable and explosive solvents, but also reduces fugitive emissions and lowers environmental treatment costs.

[0019] 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 protection scope of the present invention. Example 1

[0020] Please see Figures 1 to 17 The first embodiment of the present invention provides a novel leaching device for cottonseed meal processing. This device includes a support 101 and an external controller. A separation mechanism 200 is provided on the top of the support 101, and an leaching mechanism 300 is provided on the side of the support 101. The separation mechanism 200 includes a processing tank 201 fixedly connected to the top of the support 101, a discharge trough plate 202 symmetrically and fixedly connected to the outer wall of the processing tank 201, a sealing plate 203 slidably connected to the inner wall of the discharge trough plate 202, a screening assembly 204 disposed inside the processing tank 201, a dual servo rotary motor 205 disposed inside the screening assembly 204, and a vibration assembly 206 disposed inside the processing tank 201. The leaching mechanism 300 includes a leaching rack 301 fixedly connected to the outer wall of the support 101, a drive motor 302 symmetrically fixedly connected to the outer wall of the leaching rack 301, a conveyor belt conveying device 303 symmetrically rotatably connected to the inner wall of the leaching rack 301, a plurality of baffles 304 arranged in a ring array and fixedly connected to the outer wall of the conveyor belt conveying device 303, a conveying assembly 305 symmetrically arranged on the leaching rack 301, a mounting frame 306 symmetrically fixedly connected to the outer wall of the leaching rack 301, a position monitoring controller 307 fixedly connected to the lower surface of the top of the mounting frame 306, a scraper 308 disposed inside the conveying assembly 305, a leaching assembly 309 disposed inside the mounting frame 306, and a linkage rod 310 disposed inside the leaching assembly 309.

[0021] Furthermore, the dual servo rotary motor 205 is fixedly connected to the inner wall of the top of the conical groove plate 204b; An electrical connection is established between the dual servo rotary motor 205 and an external controller, and the drive end of the dual servo rotary motor 205 is controlled to rotate in the forward and reverse directions by the external controller. The transmission end of the conveyor belt 303 is fixedly connected to the drive end of the drive motor 302, so that the drive end of the drive motor 302 drives the conveyor belt 303 to convey cottonseed meal on the inner wall of the leaching rack 301. An electrical connection is established between the drive motor 302 and the position monitoring controller 307, so that the position monitoring controller 307 monitors whether the cotton meal particles have moved directly under the nylon cloth 309i. When the cotton meal particles move directly under the nylon cloth 309i, the position monitoring controller 307 controls the telescopic end of the drive telescopic rod 309a to extend downward. The bottom end of scraper 2 308 is attached to the top end of baffle 304, so that scraper 2 308 scrapes away excess cottonseed meal particles inside the two adjacent baffles 304 and causes the excess cottonseed meal to fall into the next two adjacent baffles 304, thus avoiding excessive difference in the content of cottonseed meal particles inside the two baffles 304.

[0022] Operating Procedure: First, the operator feeds cottonseed meal particles into the processing tank 201 through the top, allowing the particles to enter the screening component 204 for filtration. The particles are then separated into two grades based on size, with the smaller particles falling to the bottom of the processing tank 201. During the feeding process, the operator controls the dual servo rotary motor 205 via an external controller. This motor drives the vibration component 206 in the forward direction, vibrating the material inside the processing tank 201. This causes the screening component 204 to agitate the cottonseed meal at the top of the tank, improving the filtration efficiency. Subsequently, the operator controls the dual servo rotary motor 205 in the reverse direction, driving the vibration component 206. This causes the vibration component 206 to drive the screening component 204 to scrape the filtered cottonseed meal particles into the discharge trough 202. The cottonseed meal particles then pass through the discharge trough 202 and the conveying component 305 between the two baffles 304. The operator then powers on the position monitoring controller 307, causing it to monitor the position of the cottonseed meal particles. When the position monitoring controller 307 does not detect any cottonseed meal particles directly below it, it controls the two drive motors 302 to rotate simultaneously. This causes the drive motors 302 to move the conveyor belt 303 synchronously along the inner wall of the leaching rack 301. The conveyor belt 303 then moves the cottonseed meal particles directly below the position monitoring controller 307 via the baffles 304. During this movement, the scraper 308 scrapes away excess cottonseed meal particles from the interior of adjacent baffles 304, causing them to fall into the next adjacent baffle. This ensures that the cottonseed meal particle content between the two baffles 304 does not differ too much. When the cottonseed meal particles reach directly below the position monitoring controller 307, the position monitoring controller 307 stops the drive motors 302. The monitoring controller 307 controls the leaching unit 309 to start working, causing the leaching unit 309 to squeeze the cottonseed meal particles inside the baffle 304, preventing excessively large gaps between the cottonseed meal particles inside the baffle 304. Then, the operator uses an external conveying device to supply industrial-grade n-hexane into the leaching unit 309, causing the leaching unit 309 to spray industrial-grade n-hexane onto the cottonseed meal particles inside the baffle 304. Subsequently, the position monitoring controller 307 drives the baffle 304 via the drive motor 302 and the conveyor belt 303. 04 The cottonseed meal particles sprayed with industrial-grade n-hexane continue to move, causing them to move into the conveying component 305. The conveying component 305 then filters and discharges the product after the cottonseed meal particles have been leached. Subsequently, clean water is conveyed into the conveying component 305 through an external conveying device. This allows the conveying component 305 to clean the cottonseed meal particles that have entered and exited and are still attached to the outer wall of the baffle 304 and the conveyor belt 303. The cottonseed meal particles then fall into the guide device provided in the conveying component 305 for discharge. Example 2

[0023] Reference Figures 2 to 11This is the second embodiment of the present invention, which differs from the first embodiment in that: the screening component 204 includes a connecting plate 204a symmetrically fixedly connected to the inner wall of the top of the processing tank 201, a conical groove plate 204b fixedly connected between the lower surfaces of the two connecting plates 204a, an annular groove 204c formed on the inner wall of the top of the processing tank 201, six sliders 204d arranged in a ring array and slidably connected inside the annular groove 204c, a circular ring plate 204e fixedly connected to one end of the sliders 204d away from the annular groove 204c, a fixing rod 204f fixedly connected to the inner wall of the circular ring plate 204e, a spring 204g fixedly connected to the lower surface of the circular ring plate 204e, and a fixing rod 204f fixedly connected to the inner wall of the circular ring plate 204e. The separation plate 204h is attached to the bottom end of the spring 204g; the screening trough plate 204i is fixedly connected between the outer walls of the six separation plates 204h; the connecting frame 204j is fixedly connected to the bottom end of the inner wall of the screening trough plate 204i; the slide rod 204k is fixedly connected to the outer wall of the connecting frame 204j; the limiting block 204l is symmetrically fixedly connected to the outer wall of the bottom end of the slide rod 204k; the conical bottom plate 204m is fixedly connected to the inner wall of the bottom end of the processing tank 201; the sleeve rod 204n is rotatably connected to the top end of the conical bottom plate 204m; the limiting groove 204o is opened at the top end of the sleeve rod 204n; and the three scrapers 204p are arranged in a ring array and fixedly connected to the outer wall of the sleeve rod 204n. The vibration assembly 206 includes a circular plate 206a fixedly connected to the drive end of the dual servo rotary motor 205, two fixing rods 206b symmetrically fixedly connected to the inner wall of the circular plate 206a, an adjustment plate 206c fixedly connected to the bottom ends of the two fixing rods 206b, an adjustment ball 206d fixedly connected to the inner wall of the adjustment plate 206c, an adjustment rod 206e fixedly connected to the top end of the slide rod 204k, an adjustment groove 206f symmetrically opened on the outer wall of the adjustment rod 206e, three fixing blocks 206g arranged in a ring array and fixedly connected to the inner wall of the middle part of the bracket 101, a shaft 206h rotatably connected to the inner wall of the bottom end of the fixing block 206g, torsion springs 206i symmetrically sleeved on the outer walls of both ends of the shaft 206h, and a limiting block 206j fixedly connected to the lower surface of the shaft 206h.

[0024] Furthermore, the bottom end of the fixing rod 204f slides on the inner wall of the top of the separation plate 204h, and the separation plate 204h will not fall off during the process of sliding on the outer wall of the fixing rod 204f. The bottom outer wall of the screening trough plate 204i is in contact with the inner wall of the processing tank 201. The lower surface of the scraper 204p is in contact with the upper surface of the conical bottom plate 204m. The size of the limiting block 204l and the bottom of the slide rod 204k after combination is adapted to the size of the limiting groove 204o. The side of the separating plate 204h away from the conical trough plate 204b is in contact with the inner wall of the processing tank 201. The side of the scraper 204p away from the separating plate 204h is in contact with the inner wall of the processing tank 201. The upper surface of the bottom outer side of the screening trough plate 204i has an inclined surface for guiding the cottonseed meal particles.

[0025] Furthermore, the size of the adjusting ball 206d is adapted to the size of the adjusting groove 206f. The adjusting groove 206f is composed of an axially arranged straight groove and a circumferentially arranged arc groove. The two adjusting grooves 206f are connected end to end. The adjusting plate 206c slides on the outer wall of the adjusting rod 206e. The two ends of the torsion spring 206i are fixedly connected to the shaft 206h and the fixing block 206g, respectively.

[0026] Usage Process: When cottonseed meal particles enter the processing tank 201, they are guided by the upper surface of the conical trough plate 204b and enter between the screening trough plate 204i and the processing tank 201. This allows the cottonseed meal particles to undergo preliminary filtration through the screening trough plate 204i, causing smaller particles to fall onto the upper surface of the conical bottom plate 204m. Simultaneously, as the dual servo rotary motor 205 drives the circular plate 206a to rotate slowly in the forward direction, the circular plate 206a drives the second fixed rod 206b to rotate synchronously. This, in turn, drives the adjusting plate 206c to rotate synchronously via the fixed rod 206b. The adjusting plate 206c then drives the adjusting ball 206d to rotate synchronously, causing the adjusting ball 206d to press against... The arc-shaped groove inside the adjustment groove 206f rotates synchronously, causing the adjustment groove 206f to drive the adjustment rod 206e to rotate synchronously. The adjustment rod 206e then drives the slide rod 204k to rotate synchronously. The slide rod 204k, through the limiting block 204l and the limiting groove 204o, drives the sleeve rod 204n to rotate synchronously. When the sleeve rod 204n rotates, it drives the scraper 204p to rotate synchronously. The top of the scraper 204p abuts against the limiting block 206j. Since the fixed block 206g and the end of the limiting block 206j furthest from the scraper 204p are in a state of mutual abutment, the scraper 204p cannot rotate. Therefore, the scraper 204p drives the sleeve rod 204n and... The slide bar 204k remains stationary, causing the adjusting rod 206e to remain stationary. This, in turn, causes the adjusting ball 206d to move from the bottom to the top of the arc-shaped groove. Under the pressure of the adjusting ball 206d against the arc-shaped groove, the adjusting rod 206e slides downwards inside the adjusting plate 206c. This causes the adjusting rod 206e to move the slide bar 204k downwards synchronously. The slide bar 204k, through the connecting frame 204j, drives the screening trough plate 204i and the separation plate 204h downwards synchronously. The separation plate 204h slides downwards on the bottom outer wall of the fixed rod 204f, stretching the spring 204g downwards. When the adjusting plate 206c and the adjusting ball 206d are connected by dual servo rotary motors... Driven by 205, the ball rotates forward, causing the adjusting ball 206d to slide from the top of the arc-shaped groove in the adjusting groove 206f to the top of the straight groove. At this time, the adjusting ball 206d cannot contact the straight groove in the vertical direction. At this time, the spring 204g pulls the separating plate 204h upward on the bottom outer wall of the fixed rod 204f, causing the inner wall of the separating plate 204h to collide with the bottom of the fixed rod 204f, causing the separating plate 204h to vibrate. This causes the separating plate 204h to drive the screening trough plate 204i to vibrate synchronously. During the vibration, the screening trough plate 204i shakes the cottonseed meal particles between the screening trough plate 204i and the processing tank 201, thereby improving the filtration effect of the cottonseed meal particles. After the cottonseed meal granules are fed in and the separating plate 204h remains stable, the dual servo rotary motor 205 drives the circular plate 206a to rotate slowly in the opposite direction. This causes the circular plate 206a to drive the adjusting plate 206c to rotate synchronously in the opposite direction via the fixed rod 206b. The adjusting plate 206c then drives the adjusting ball 206d to rotate in the opposite direction. When the adjusting ball 206d rotates in the opposite direction, it contacts the straight groove inside the adjusting groove 206f. This straight groove then drives the adjusting rod 206e to rotate synchronously in the opposite direction. 6e drives the slide bar 204k to rotate synchronously in the opposite direction. This causes the slide bar 204k to rotate synchronously in the opposite direction through the contact between the limiting block 204l and the limiting groove 204o. The sleeve rod 204n then drives the scraper 204p to rotate synchronously. During the reverse rotation of the scraper 204p, it intermittently contacts the limiting block 206j, causing the limiting block 206j to intermittently rotate upwards counterclockwise at the bottom end of the fixed block 206g. This prevents the limiting block 206j from contacting the scraper 204p. 04p is limited, which allows the slide rod 204k to drive the sleeve rod 204n and scraper 204p to rotate in opposite directions. During the rotation of scraper 204p, the cottonseed meal particles at the top of the conical bottom plate 204m move towards one side of the discharge trough plate 202 at the bottom of the processing tank 201, so that the cottonseed meal particles at the top of the conical bottom plate 204m enter the discharge trough plate 202 at the bottom of the processing tank 201. At the same time, the slide rod 204k drives the screening trough plate 204i and the separation plate through the connecting frame 204j. The 204h synchronous reverse rotation causes the cottonseed meal particles between the screening trough plate 204i and the processing tank 201 to move towards the side of the discharge trough plate 202 located near the bottom of the processing tank 201. This allows the cottonseed meal particles between the screening trough plate 204i and the processing tank 201 to enter the discharge trough plate 202 located at the top of the processing tank 201. Thus, the cottonseed meal is filtered, separated, and output. This prevents the problems of small particles easily being lost with the mixed oil and large particles easily forming voids when the two different sizes of cottonseed meal particles are subsequently leached separately.

[0027] Through the synergistic action of the screening component 204 and the vibration component 206 in the separation mechanism 200, cottonseed meal particles are accurately graded according to their volume. In addition, through the screening trough plate 204i and the vibration structure driven by the dual servo rotary motors 205, large and small cottonseed meal particles can be efficiently separated and conveyed to the conveyor belt conveyor 303 of the leaching mechanism 300 through the corresponding discharge trough plate 202. This allows the graded cottonseed meal particles to be processed in an independent leaching channel, avoiding the problems of small particles being easily entrained by solvent and forming entrainment, and large particles easily forming gaps and causing channeling during mixed leaching. At the same time, through the combination structure of the mounting plate 309h and nylon cloth 309i in the leaching component 309, the elastic pressure of the spring 309g compacts the material layer, eliminating the pore channels in the material layer and avoiding particle breakage caused by rigid contact, further blocking the generation of channeling and entrainment, and ensuring the stability of the leaching process. Example 3

[0028] Reference Figures 12 to 17 This is the third embodiment of the present invention. This embodiment differs from the previous two embodiments in that: the conveying assembly 305 includes a transparent cover plate 305a symmetrically fixedly connected to the outer wall of the leaching rack 301, a feed trough 305b opened on the upper surface of the transparent cover plate 305a near the support 101, a guide trough 305c symmetrically opened on the inner wall of the leaching rack 301, a guide plate 305d fixedly connected to the inner wall of the guide trough 305c, a gauze 305e fixedly connected to the inner wall of the guide plate 305d, a mounting block 305f symmetrically fixedly connected to the outer wall of the leaching rack 301 away from the support 101, a water sprayer 305g fixedly connected to the outer wall of the mounting block 305f near the conveyor belt 303, a connection port 305h fixedly connected to the outer wall of the water sprayer 305g away from the conveyor belt 303, and a guide plate 305i symmetrically fixedly connected to the outer wall of the leaching rack 301. The leaching assembly 309 includes a drive telescopic rod 309a that is fixedly connected to the inner wall of the mounting bracket 306, a fixed rod 309b that is fixedly connected to the telescopic end of the drive telescopic rod 309a, a connecting port 309c that is fixedly connected to the outer wall of the fixed rod 309b, a mounting circular plate 309d that is fixedly connected to the outer wall of the bottom end of the fixed rod 309b, four connecting rods 309e that are arranged in a ring array and fixedly connected to the outer wall of the mounting circular plate 309d, a water sprayer 309f that is fixedly connected to the bottom end of the fixed rod 309b, a spring 309g that is fixedly connected to the bottom end of the four connecting rods 309e, a mounting plate 309h that is fixedly connected to the bottom end of the spring 309g, and a nylon cloth 309i that is fixedly connected to the inner wall of the mounting plate 309h.

[0029] Furthermore, the top of scraper 2 308 is fixedly connected to the inner wall of the top of transparent cover 305a, guide plate 1 305d is detachable, connection port 1 305h is used to connect to an external device for conveying clean water, and the lower surface of guide channel 305c is on the same horizontal plane as the upper surface of conveyor belt 303.

[0030] Furthermore, the linkage rod 310 is fixedly connected to the outer wall of the telescopic end of the drive telescopic rod 309a, and the end of the linkage rod 310 away from the drive telescopic rod 309a slides on the inner wall of the sealing plate 203. The connection port 309c is used to connect with an external device for conveying industrial-grade n-hexane. An electrical connection is established between the drive telescopic rod 309a and the position monitoring controller 307. The dimensions of the nylon cloth 309i combined with the mounting plate 309h are adapted to the dimensions of the loading groove between the two adjacent baffles 304. The nylon cloth 309i, with its own weight and the slight elastic pressure of the spring 309g, can compact the loose areas on the surface of the material layer, eliminate the pore channels inside the material layer, and prevent industrial-grade n-hexane from flowing quickly through the gaps to form channels. At the same time, the grid does not have rigid contact with the material layer, thus avoiding crushing the material blank and generating new fine powder.

[0031] It should be noted that the connection ports 309c on the upper and lower sides of the leaching rack 301 are respectively connected to industrial-grade n-hexane conveying devices containing different concentrations.

[0032] Usage: When the baffle 304 containing cottonseed meal granules is not directly below the position monitoring controller 307, the drive telescopic rod 309a is in an unextended state. Therefore, the drive telescopic rod 309a is suspended in mid-air, contacting the sealing plate 203 via the linkage rod 310, and the sealing plate 203 does not block the discharge chute 202. During the feeding of cottonseed meal granules, the drive motor 302 is in operation. When the cottonseed meal granules inside the processing tank 201 enter the interior of the two baffles 304 through the discharge chute 202 and the feed chute 305b, the drive motor 302, through the conveyor belt conveyor 303, moves the cottonseed meal granules between the two baffles 304. Move towards the side closer to the mounting bracket 306. When the cottonseed meal particles move directly below the position monitoring controller 307, the position monitoring controller 307 controls the drive telescopic rod 309a to extend downwards. This causes the drive telescopic rod 309a's linkage rod 310 to abut against the sealing plate 203 and slide downwards inside the discharge trough plate 202. The sealing plate 203 then seals the discharge trough plate 202. This causes the drive telescopic rod 309a to move the fixed rod 309b downwards synchronously. The fixed rod 309b then moves the mounting plate 309d, connecting rod 309e, and water sprayer 309f downwards synchronously. This causes the mounting plate 309h and nylon cloth 309i to move to the two mounting brackets. Inside the baffle 304 containing cottonseed meal particles, the bottom of the water sprayer 309f abuts against the top of the baffle 304. This allows the nylon cloth 309i, under its own weight and with the slight elastic pressure of the spring 309g, to compact the loose areas on the surface of the material layer, eliminating pore channels within the material layer and preventing industrial-grade n-hexane from flowing rapidly through the gaps and forming channels. Simultaneously, the grid does not rigidly contact the material layer, avoiding crushing the material and generating new fine powder. Subsequently, industrial-grade n-hexane is sprayed onto the upper surface of the nylon cloth 309i through the connection port 309c and the water sprayer 309f. When the nylon cloth 309i absorbs the industrial-grade n-hexane and reaches maximum saturation, it then penetrates the cottonseed meal. The top of the granules is supplied with industrial-grade n-hexane. This prevents the excessive spraying pressure from the sprayer 309F directly impacting the cottonseed meal granule pile, causing local depressions and scouring grooves on the surface of the material layer. This creates channeling channels where the n-hexane would flow rapidly through the material layer without fully contacting the granules, resulting in insufficient leaching and a significant increase in residual oil content. At the same time, the strong impact force will crush some cottonseed meal granules, producing a large amount of fine powder. The high-pressure flow will carry the fine powder and small particles into the mixed oil collection system, causing entrainment problems and clogging the pipes and heat exchangers of the subsequent distillation system. This increases the frequency of equipment cleaning and maintenance costs, thereby ensuring the leaching effect of the cottonseed meal granules.

[0033] Different concentrations of industrial-grade n-hexane can be introduced through the connection ports 309c on the upper and lower sides of the leaching rack 301. Large-volume particles correspond to high-concentration solvents and slightly longer leaching times, while small-volume particles correspond to low-concentration solvents and shorter leaching times, ensuring that both types of particles are in the optimal extraction state. Compared with mixed leaching, the overall residual oil rate can be reduced. On the other hand, the nylon cloth 309i adopts an immersion-type solvent delivery method, avoiding the problem of local depressions and scouring grooves on the surface of the material layer caused by the impact of high-pressure spray on the particles, thus ensuring the leaching effect of cottonseed meal particles. In addition, the scraper 308 quantitatively scrapes the cottonseed meal particles in the baffle 304 to ensure uniform material layer thickness, further improving the leaching uniformity and cottonseed meal protein activity.

[0034] Through the electrical linkage of the position monitoring controller 307, drive motor 302, and drive telescopic rod 309a, the entire process of cottonseed meal particle conveying, grading, and leaching is automated. The position monitoring controller 307 accurately identifies the particle position and automatically triggers the operation of the leaching component 309 and the sealing or opening of the discharge trough plate 202, reducing manual intervention. The detachable guide plate 305d and gauze 305e facilitate cleaning and maintenance, while scraper 204p and scraper 308 can respectively clean the inner wall of the processing tank 201 and residual particles on the baffle 304, reducing the probability of equipment blockage. At the same time, the solvent is impregnated and penetrated through the nylon cloth 309i, reducing solvent splashing and atomization caused by high-pressure spraying, reducing the concentration of solvent vapor in the workshop, which not only meets the safety use regulations for flammable and explosive solvents, but also reduces fugitive emissions and lowers environmental treatment costs.
