Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of starch transportation equipment, and particularly relates to a transportation device with a draining function for pea starch. BACKGROUND

[0002] Pea starch is a natural plant starch extracted from peas and belongs to the core category of edible starch. The core component is starch, and the outstanding features are gluten-free, low-fat and low-protein. Pea starch is not only a commonly used raw material in food industry production and daily cooking, but also widely used in various industrial processing scenes due to its wide adaptability. In the production process of pea starch, after removing impurities such as protein and dietary fiber through separation and purification process, the pure starch milk obtained needs to be transported to the subsequent dehydration and drying process through the conveying equipment.

[0003] The existing pure starch milk contains a large amount of water during the conveying process to the dehydration and drying process, which leads to frequent shutdown for manual cleaning of residues. In addition, the water soaking for a long time and the adhesion of starch can cause the rapid wear of the conveying contact parts, which need to be frequently replaced to avoid pollution, seriously damaging the continuity of production operation. At the same time, the water that has not been separated cannot be collected in a targeted manner. Part of it will flow with the starch milk during the conveying process to form surface residues, and part of it will splash due to conveying vibration and material extrusion, polluting the equipment body and the surrounding production environment, causing water waste, and also causing microorganisms to breed due to the combination of moisture residues and starch, affecting food production hygiene. In addition, the dispersed water cannot be concentrated and guided, resulting in uneven distribution of water in the starch milk, further increasing the processing difficulty of subsequent processing. SUMMARY

[0004] In order to solve the above technical problems, the present application provides a transportation device with a draining function for pea starch.

[0005] To achieve the above purpose, the present application provides the following technical scheme: a transportation device with a draining function for pea starch, comprising: a conveyor, wherein the conveyor is provided with a draining part for absorbing water in the starch milk, and the draining part is provided with an extruding part for extruding the starch milk.

[0006] The draining component includes a mounting plate one fixedly connected to the top of the conveyor mounting frame. A mounting groove is formed on one side of the mounting plate, and a rotating roller is rotatably connected within the mounting groove. A water-absorbing layer is fitted onto the outer surface of the rotating roller. A motor is fixedly connected to one side of the mounting plate, and the motor's output end passes through the mounting plate one and is fixedly connected to the rotating roller. A second mounting plate is fixedly connected to the top of the conveyor mounting frame. A lifting groove is formed through the side of the second mounting plate, and a lifting block is slidably inserted into the lifting groove. A water storage box is fixedly connected to one end of the lifting block. A fixing plate is fixedly connected to the inner side of the second mounting plate, and a drainage groove is formed through the fixing plate. A scraper is fixedly connected to the bottom of the fixing plate, and one end of the scraper abuts against the water-absorbing layer.

[0007] The motor drives the rotating roller to rotate the water-absorbing layer synchronously. The outer surface of the water-absorbing layer contacts the pure starch milk and absorbs water. As it rotates, it gradually moves to the scraper. Under the combined action of continuous rotation and the squeezing of the scraper, the water is scraped out and flows along the inclined surface to the drainage trough, eventually falling into the water storage box.

[0008] As a further embodiment of the present invention: the scraper is in an inclined state, and the side near the water storage box is the lower end. The water storage box is V-shaped, wider at the top and narrower at the bottom. Its upper width is the same as the width of the mounting plate. The drainage groove is set directly above the water storage box. The length of the water absorption layer is the same as the width of the conveyor belt.

[0009] As a further embodiment of the present invention: an overflow hole is provided through the side end of the water storage box, a guide groove is provided on the outer contour surface of the water storage box, and the guide groove is connected to the overflow hole. The guide groove and the overflow hole are located above the gap between the belt side end of the conveyor and the inner side of the conveyor mounting frame.

[0010] As a further embodiment of the present invention: a U-shaped mounting frame is fixedly connected to the bottom of the inside of the conveyor mounting frame, and a guide platform with a triangular cross-section is fixedly connected to the bottom of the inside of the mounting frame.

[0011] As a further embodiment of the present invention: the extrusion member includes a support plate fixedly connected to one end of the lifting block, a spring fixedly connected to the bottom end of the support plate, the bottom end of the spring fixedly connected to the top end of the conveyor mounting frame, the spring initially lifts the support plate, so that the lifting block connected to the support plate is lifted to the top limit position of the lifting groove, and a support rod is fixedly connected to the conveyor mounting frame, the support rod is located inside the O-shaped belt of the conveyor and directly below the water storage box.

[0012] As a further embodiment of the present invention: the outer circular surface of the rotating roller located above the gap between the belt side of the conveyor and the inner side of the conveyor mounting frame is fixedly connected to an installation block, the installation block having a slot on the side facing the water storage box, and a limiting groove being formed on the side end of the installation block, and the limiting groove communicating with the slot.

[0013] As a further embodiment of the present invention: a push plate is inserted into the slot, the push plate having an arc surface facing downwards towards the water storage box, and a reset post is fixedly connected to the side end of the slot, with the reset post penetrating the limiting groove.

[0014] As a further embodiment of the present invention: a connecting plate is fixedly connected to the inner side of the mounting plate, the connecting plate is located obliquely below the rotating roller and outside the rotation trajectory of the push plate, an L-shaped reset plate is fixedly connected to the inner side of the connecting plate, a reset groove is provided on the inner side of the reset plate, and the reset plate is located at the side end of the mounting block.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention achieves gradient-style comprehensive water absorption of pure starch milk by setting multiple sets of rotating rollers with different rotation frequencies, combined with a water-absorbing layer with the same width as the conveyor belt, which greatly improves the water adsorption efficiency. By using an inclined scraper and a drainage trough directly opposite the water storage box, combined with a V-shaped water storage box structure that is wider at the top and narrower at the bottom, the scraped water is quickly guided and collected, avoiding water residue or splashing. By setting an overflow hole and a guide trough in the water storage box, and placing it above the gap between the conveyor belt and the mounting frame, combined with a bottom U-shaped mounting frame and a triangular guide platform, excess water is guided and collected in an orderly manner, preventing water from contaminating the equipment or starch milk. The rotating rollers driven by the motor rotate synchronously with the water-absorbing layer, combined with the scraper squeezing and dehydrating the water-absorbing layer, the water-absorbing layer can be recycled and reused without frequent replacement of water-absorbing components, ensuring continuous operation.

[0017] 2. This invention links the rotating rollers of the extrusion component and the dewatering component, using an installation block to drive a push plate to move the water storage box up and down along the lifting groove, achieving automatic extrusion and dehydration of pure starch milk. No additional power source is required, reducing energy consumption. Through the elastic support and reset action of the spring, combined with the straight and curved surface design of the push plate's bottom end, the water storage box can automatically complete the extrusion and reset cycle, ensuring the continuity and stability of the extrusion operation and adapting to the continuous conveying rhythm of the conveyor. The support rod supports the conveyor belt, preventing excessive belt deformation during extrusion, ensuring uniform extrusion force, and efficiently squeezing out free water from the starch milk, reducing the adsorption load on the subsequent absorbent layer. The reset column, in conjunction with the reset groove of the L-shaped reset plate, enables the push plate to automatically extend and retract, ensuring the reliability of the extrusion mechanism's cyclic operation. Simultaneously, the elastic extrusion method avoids excessive damage to starch granules, ensuring starch quality. Attached Figure Description

[0027] 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.

[0028] Reference Figures 1-8 In this embodiment of the invention, a pea starch transport device with a draining function includes: a conveyor 1, a draining component 2 for absorbing moisture in pure starch milk transported on the conveyor 1, and an extrusion component 3 for extruding the starch milk before the draining component 2 absorbs the moisture in the pure starch milk.

[0029] The draining component 2 includes a mounting plate 21, a rotating roller 22, a water-absorbing layer 23, a motor 24, a mounting plate 25, a lifting groove 26, a lifting block 27, a water storage box 28, a fixing plate 29, a drainage groove 210, a scraper 211, an overflow hole 212, a guide groove 213, a mounting frame 214, and a guide platform 215. The mounting plate 21 is rigidly connected to the top of the conveyor 1 mounting frame using high-strength stainless steel bolts to ensure load-bearing stability. Its side end has a mounting groove precisely matched to the shaft diameters at both ends of the rotating roller 22. Wear-resistant deep groove ball bearings are embedded in the mounting groove to reduce frictional resistance and wear during the rotation of the rotating roller 22. The rotating roller 22 is made of stainless steel. The hollow steel roller body reduces overall weight while ensuring structural strength. Its outer surface is secured with an absorbent layer 23 via ring-shaped buckles and positioning pins. The absorbent layer 23 is made of a composite material of food-grade superabsorbent resin and medical-grade sponge, achieving an absorbency of over thirty times its own weight. Its length perfectly matches the width of the conveyor belt 1, ensuring complete coverage of the starch milk. A motor 24 is fixedly connected to the side of the mounting plate 21 via a mounting base and fastening bolts. The output end of the motor 24 passes through the mounting plate 21 via a flexible coupling and is rigidly connected to the shaft end of one end of the rotating roller 22. The speed can be adjusted via a frequency converter to adapt to different conveying capacity requirements. The conveyor 1 is installed... Two mounting plates 25 are symmetrically welded to the top of the frame. Vertical lifting grooves 26 are formed on opposite sides of each mounting plate 25. The inner walls of the lifting grooves 26 are finely polished. A lifting block 27 is fitted with the lifting groove 26 with a clearance fit. One end of the lifting block 27 is fixedly connected to a water storage box 28 via full welding. The water storage box 28 has a V-shaped structure, wider at the top and narrower at the bottom. This V-shaped structure effectively constrains the internal water flow trajectory. Combined with the precise guiding design of the overflow hole 212 and the guide channel 213, even if the water storage box 28 moves up and down with the lifting block 27, it prevents water from flowing out randomly due to inertia, ensuring that the water flows out only along the preset path. The upper width is the same as that of the mounting plate. The width of plate 21 is perfectly matched to ensure no side leakage when receiving water. The inner side of the mounting plate 25 is fastened to the fixing plate 29 by bolts. The fixing plate 29 is a rectangular stainless steel plate with a drainage groove 210 evenly cut through the middle along the length direction, which precisely corresponds to the area directly above the water storage box 28 to ensure the accuracy of water diversion. The bottom end of the fixing plate 29 is fixedly connected to the scraper 211 by an integrated molding process. The scraper 211 is made of food-grade wear-resistant silicone material. One end is in close contact with the surface of the water-absorbing layer 23. The squeezing pressure can be finely adjusted by the installation position of the fixing plate 29. The whole plate is tilted, with the side closer to the water storage box 28 being the lower end, forming a natural diversion slope.

[0030] The water storage box 28 has an overflow hole 212 through the side end. The outer contour surface of the water storage box 28 is integrally formed with a U-shaped guide groove 213. The guide groove 213 is connected to the overflow hole 212. The guide groove 213 and the overflow hole 212 are together located directly above the gap between the belt side end of the conveyor 1 and the inner side of the mounting frame of the conveyor 1, so as to prevent water from dripping onto the belt or the surface of the mounting frame.

[0031] The bottom of the mounting frame of conveyor 1 is fixedly connected to a U-shaped mounting frame 214 by welding. The mounting frame 214 is made of stainless steel square tube and its length is the same as the length of the draining section of conveyor 1. The bottom of its interior is fixedly connected to a guide platform 215 with an isosceles triangle cross section by expansion bolts. The surface is polished to ensure that water flows down quickly without stagnation. When conveyor 1 starts, its belt drives the pure starch milk on the surface to move smoothly towards the draining part 2 area. At the same time, the motor 24 is powered on and drives the rotating roller 22 to rotate at a preset speed. The water-absorbing layer 23 sleeved on the outer circle of the rotating roller 22 rotates together. When the starch milk enters the effective range of the water-absorbing layer 23, the composite sponge material of the water-absorbing layer 23 comes into full contact with the starch milk through the high porosity structure, and efficiently absorbs the remaining free water in the starch milk.

[0032] As the rotating roller 22 continues to rotate, the water-absorbing layer 23, which is saturated with water, gradually moves to the scraper 211 at the bottom of the fixed plate 29. Under the continuous driving force of the rotating roller 22 and the fixed squeezing action of the scraper 211, the water absorbed in the water-absorbing layer 23 is fully squeezed out. Because the scraper 211 is inclined and the side closest to the water storage box 28 is the lower end, the squeezed water flows naturally along the inclined surface of the scraper 211 to the drainage groove 210 on the fixed plate 29. After being guided by the drainage groove 210, it falls precisely into the V-shaped water storage box 28 below for centralized collection. As the draining operation continues, the water level in the water storage box 28 gradually rises. When the water level reaches a certain level... When the water reaches the height of the overflow hole 212, excess water flows out from the overflow hole 212 at a uniform speed. Guided by the U-shaped guide channel 213, it falls smoothly along the gap between the side of the conveyor belt 1 and the inner side of the mounting frame, and finally lands on the triangular guide platform 215 inside the U-shaped mounting frame 214. Under the guidance of the inclined surface of the guide platform 215, the water quickly flows to both sides and flows smoothly to the liquid storage devices preset on both sides of the conveyor 1, realizing the recycling and reuse of water. This process is a fully automatic closed-loop water recycling process, which does not require manual shutdown for drainage operations, fundamentally reducing manual intervention and effectively reducing labor costs. At the same time, the triangular guide platform 215... The design of diverting water to both sides is specifically designed to collect and process the water discharged to the left and right sides of the conveyor belt when the starch is squeezed by the water storage box 28. Through the guidance of the guide platform and the cooperation of the liquid storage devices on both sides, the efficient collection and reuse of this water is achieved. The conveyor 1 is equipped with multiple sets of draining components 2, and each set of rotating rollers 22 rotates at different frequencies. The multiple sets of draining components 2 correspond to the gradient squeezing and water absorption operations of multiple sets of water storage boxes 28. Even if there is an intermittent downward pressure in a single set of water storage boxes 28, the subsequent sets of water storage boxes 28 can also supplement the pressure of the starch milk that has not been fully squeezed, ensuring that all starch milk can undergo a full squeezing and water absorption process, completely solving the problem of some starch not being squeezed, and ensuring the overall effect of the draining technology. The starch milk will go through multiple rounds of gradient adsorption in sequence, further reducing the moisture content to the target range.

[0033] By employing a food-grade, highly absorbent composite sponge absorbent layer 23 with the same width as the conveyor belt 1, and combining it with multiple sets of rotating rollers 22 at different speeds, comprehensive coverage and gradient water absorption of the pure starch milk are achieved, significantly improving water adsorption efficiency and ensuring a uniform reduction in the moisture content of the starch milk. The design incorporates an inclined, wear-resistant silicone scraper 211 and a drainage channel 210, combined with a V-shaped water storage box 28 structure that is wider at the top and narrower at the bottom, creating a closed-loop process from squeezing to guiding to collection of the squeezed water. This prevents water splashing or residue and improves collection efficiency. Furthermore, the water storage box 28 is equipped with an overflow hole 212 and a U-shaped guide channel 213, along with a bottom... The U-shaped mounting frame 214 and the triangular guide platform 215 construct a complete water diversion and recycling system, ensuring that excess water is discharged in an orderly manner and collected centrally. This reduces water waste and avoids water contamination of equipment or starch milk. The fully automatic diversion and recycling system does not require manual shutdown for drainage. Compared with the traditional manual drainage mode, it greatly saves labor costs and downtime, ensuring the continuity of production. Through the squeezing cooperation between the rotating roller 22 driven by the motor 24 and the scraper 211, the water absorption layer 23 is recycled and reused. There is no need to frequently disassemble and replace the water absorption components, effectively ensuring the continuity of production and reducing consumable consumption and labor costs.

[0034] The extrusion component 3 includes a support plate 31, a spring 32, a support rod 33, a mounting block 34, a slot 35, a limiting groove 36, a push plate 37, a reset column 38, a connecting plate 39, a reset plate 310, and a reset groove 311. The support plate 31 is a rectangular stainless steel plate, which is fixedly connected to one end of the lifting block 27 by welding. The connection is reinforced to ensure load-bearing strength. The bottom end of the support plate 31 is fixedly connected to the spring 32 by a mounting seat and fastening bolts. The spring 32 is a food-grade stainless steel compression spring with a stable elastic coefficient. In the initial state, it has sufficient elasticity to lift the support plate 31, thereby driving the lifting block 27 to the top limit position of the lifting groove 26, forming the initial standby state. The bottom end of the spring 32 is rigidly connected to the top of the conveyor 1 mounting frame by a mounting seat to ensure that it does not shift when subjected to force. The support rod 33 is fixedly connected to the inner side of the conveyor 1 mounting frame by welding. It is horizontally set inside the O-shaped belt of the conveyor 1 and is precisely located directly below the water storage box 28 to ensure stable support during extrusion.

[0035] The rotating roller 22 is located on the outer circular surface above the gap between the side end of the conveyor belt 1 and the inner side of the mounting frame. Multiple sets of mounting blocks 34 are evenly distributed and fixed along the circumference. The mounting blocks 34 are rectangular steel structures and are fastened to the outer circular surface of the rotating roller 22 by bolts. A slot 35 adapted to the thickness of the push plate 37 is opened on the side facing the water storage box 28. A long strip-shaped limiting groove 36 is opened on the side end of the mounting block 34 along the length direction. The width of the limiting groove 36 is slightly larger than the diameter of the reset column 38 and is completely connected to the slot 35 to form a sliding guide channel. The push plate 37 is made of stainless steel and the lower part of the side facing the water storage box 28 is processed into a smooth arc surface. The push plate 37 can slide freely along the slot 35. The side end of the slot 35 is fixed to the reset column 38 by threaded connection. The reset column 38 is a stainless steel cylinder with one end passing through the limiting groove 36 and extending to the outside, and is fixedly connected to the push plate 37. It can slide synchronously with the push plate 37 along the limiting groove 36 to play a limiting and guiding role.

[0036] A connecting plate 39 is fixedly connected to the inner side of the mounting plate 21 by bolts. The connecting plate 39 is positioned diagonally below the rotating roller 22, avoiding the rotation trajectory of the push plate 37 to prevent interference during movement. An L-shaped reset plate 310 is fixedly connected to the inner side of the connecting plate 39 by welding. The reset plate 310 is made of stainless steel and has a reset groove 311 on its inner side along the rotation direction. The reset groove 311 has an arc-shaped structure with a chamfered entrance to facilitate the entry of the reset column 38. The groove width is clearance-fitted with the diameter of the reset column 38. The reset plate 310 is integrally set on the side end of the mounting block 34 to ensure that the reset column 38 can accurately align with the reset groove 311 when the mounting block 34 rotates. When the conveyor 1 starts, it drives the pure starch milk towards the extruder 3. During the area movement, the motor 24 in the draining component 2 synchronously drives the rotating roller 22 to rotate. The rotating roller 22 drives multiple sets of mounting blocks 34 on the outer circular surface to perform circumferential motion. During the rotation of the mounting block 34, the bottom surface of the push plate 37 in its slot 35 first abuts against the outer wall of the water storage box 28. As the rotating roller 22 continues to apply force, the push plate 37 generates a downward axial thrust, pushing the water storage box 28 and the lifting block 27 to move vertically downward smoothly along the lifting groove 26 of the mounting plate 25. During this process, the support plate 31 connected to the water storage box 28 moves downward synchronously, causing the spring 32 to gradually contract and deform under downward pressure. The bottom of the water storage box 28 gradually approaches and finally contacts the starch milk, applying uniform extrusion pressure. The V-shaped shape of the water storage box 28... The design of the structure and the height of the overflow hole 212 prevents internal water from flowing out due to inertia during reciprocating motion, ensuring that the water is always in a controllable collection state. At this time, the support rod 33 located directly below the water storage box 28 provides stable support, preventing the conveyor belt 1 from sinking due to excessive compression, ensuring uniform compression force, and efficiently squeezing out a large amount of free water from the starch milk. When the water storage box 28 moves down to the bottom limit position of the lifting groove 26, it can no longer move. As the rotating roller 22 continues to rotate, the contact position between the push plate 37 and the water storage box 28 changes from the bottom straight surface to the lower arc surface. Since the water storage box 28 is in the limited state, the push plate 37 is subjected to a reverse thrust and moves inward along the slot 35 into the mounting block 34. The reset column 38 slides synchronously along the limiting groove 36 until the push plate 37 and the water storage box 28 are completely misaligned, and the water storage box 28 is no longer under force. Then, the contracted spring 32 releases the reset thrust, which drives the lifting block 27 to move upward along the lifting groove 26 through the support plate 31. The water storage box 28 is reset to the initial position. The push plate 37, which is retracted into the slot 35, continues to rotate with the rotating roller 22. When it rotates to the reset plate 310 inside the connecting plate 39, the reset column 38 on the push plate 37 accurately enters the reset groove 311 of the reset plate 310. Under the guiding and limiting action of the reset groove 311, the push plate 37 slides outward along the slot 35 to reset and return to the initial extended state, preparing for the next extrusion operation and realizing the extrusion cycle.

[0037] The above solution involves linking the rotating rollers 22 of the extruder 3 and the drainer 2, using the mounting block 34 to drive the push plate 37 to lift the water storage box 28. This achieves synchronized extrusion, conveying, and draining actions, eliminating the need for an additional power source and effectively reducing energy consumption and manufacturing costs. The use of food-grade stainless steel compression springs 32 for elastic support and reset, combined with the differentiated structure of the straight and curved surfaces at the bottom of the push plate 37, allows the water storage box 28 to automatically complete the cycle from downward extrusion to disengagement and then back to standby. This ensures precise matching between the extrusion operation and the continuous conveying rhythm of the conveyor 1, guaranteeing continuous production. Furthermore, the gradient arrangement of multiple drainer 2 units allows for the removal of starch not covered by a single water storage box 28. The starch slurry undergoes a pressure replenishment process to completely resolve the issue of some starch not being squeezed out due to intermittent pressure, ensuring the stability of the drainage effect. By setting a support rod 33 inside the conveyor belt 1, precisely aligned with the area directly below the water storage box 28, excessive belt deformation during extrusion is avoided, ensuring uniform and stable extrusion force. This efficiently squeezes out free water from the starch slurry, significantly reducing the adsorption load on the subsequent water absorption layer 23 and improving overall drainage efficiency. By setting a reset column 38 in conjunction with the reset groove 311 of the L-shaped reset plate 310, the push plate 37 automatically retracts and resets, ensuring the reliability of the extrusion mechanism's cyclic operation. At the same time, the elastic extrusion method can buffer the extrusion force, avoiding excessive extrusion damage to the starch granules and ensuring the quality of subsequent starch processing applications.

[0038] The working principle of this invention is as follows: As the conveyor 1 starts running, its belt drives the pure starch milk on its surface to move smoothly towards the extruder 3 area along the conveying direction. At the same time, the motor 24 in the draining component 2 drives the rotating roller 22 to rotate synchronously. The rotation of the rotating roller 22 causes multiple sets of mounting blocks 34 fixed on its outer circular surface to move in a circular motion. During the rotation of the mounting block 34, the bottom straight surface of the push plate 37 inserted in its slot 35 first abuts against the outer wall of the water storage box 28. As the rotating roller 22 continues to apply force, the push plate 37 generates a downward thrust, pushing the water storage box 28 and the lifting block 27 to move vertically downward along the lifting groove 26 of the mounting plate 25. During this process, the spring 32 connected to the water storage box 28 through the support plate 31 is subjected to Under downward pressure, the water storage box 28 gradually contracts and deforms, and its bottom end gradually approaches the pure starch milk on the conveyor belt 1 until it fully contacts the starch milk and applies pressure. At this time, the support rod 33, located inside the O-shaped belt of the conveyor 1 and directly below the water storage box 28, provides stable support, preventing the belt from sinking due to excessive pressure, and ensuring that the water storage box 28 applies uniform pressure to the starch milk, efficiently squeezing out a large amount of free water inside the starch milk. When the water storage box 28 moves downward to the bottom limit position of the lifting groove 26, it can no longer move downward. As the rotating roller 22 continues to rotate, the contact position between the push plate 37 and the water storage box 28 changes from the bottom straight surface to the arc surface facing the side of the water storage box 28. In the limited position, the push plate 37 is pushed in the opposite direction by the water storage box 28, and retracts and moves along the slot 35 into the mounting block 34. At the same time, the reset pin 38 slides synchronously along the limiting groove 36 until the push plate 37 and the water storage box 28 are completely misaligned, and the water storage box 28 is no longer subjected to downward pressure. At this time, the contracted spring 32 releases the reset thrust, which drives the lifting block 27 to move upward along the lifting groove 26 through the support plate 31. The water storage box 28 is then reset to its initial position, and the push plate 37, which is retracted into the slot 35, continues to rotate with the rotating roller 22. When it rotates to the L-shaped reset plate 310 inside the connecting plate 39, the reset pin 38 on the push plate 37 just enters the reset groove 311 of the reset plate 310. Under the guiding and limiting action of the reset groove 311, the push plate 37... Plate 37 slides outward along slot 35 to reset to its initial extended state, preparing for the next extrusion operation. The pure starch milk after extrusion continues to move with conveyor 1 and enters the water-absorbing layer 23 of the draining component 2. Since the length of the water-absorbing layer 23 is consistent with the belt width of conveyor 1, its outer surface can fully contact the starch milk, efficiently absorbing the remaining water in the starch milk. As the rotating roller 22 continues to rotate, the water-absorbing layer 23 area, which is full of water, gradually moves to the scraper 211 at the bottom of the fixed plate 29. Under the continuous driving force of the rotating roller 22 and the fixed extrusion action of the scraper 211, the water absorbed in the water-absorbing layer 23 is fully scraped out. Because the scraper 211 is inclined and the side closer to the water storage box 28 is the lower end,The scraped water flows naturally along the inclined surface of the scraper 211 to the drainage trough 210 on the fixed plate 29. The drainage trough 210 is directly above the V-shaped water storage box 28. After being precisely guided by the drainage trough 210, the water falls into the water storage box 28 for collection. As the draining operation continues, the water collected in the water storage box 28 gradually increases. When the water level reaches the height of the overflow hole 212, the excess water flows out from the overflow hole 212. Guided by the flow guide groove 213 on the outer contour surface of the water storage box 28, it falls along the gap between the side of the conveyor belt 1 and the inner side of the mounting frame, and finally falls on the triangular flow guide platform 215 in the U-shaped mounting frame 214 at the bottom of the mounting frame of the conveyor 1. Under the guidance of the inclined surface of the flow guide platform 215, the water flows smoothly towards The pre-installed liquid storage devices on both sides of the conveyor 1 enable centralized water recovery. Furthermore, because the dewatering components 2 are equipped with multiple sets of rotating rollers 22, each with a different rotation frequency, the starch milk undergoes multiple rounds of gradient dewatering during transport, further enhancing the water removal effect. By setting multiple sets of rotating rollers 22 with different rotation frequencies, combined with a water-absorbing layer 23 of the same width as the conveyor belt 1, gradient and comprehensive water absorption of the pure starch milk is achieved, significantly improving water adsorption efficiency. The use of an inclined scraper 211 and a drainage trough 210 directly opposite the water storage box 28, combined with the V-shaped structure of the water storage box 28 (wider at the top and narrower at the bottom), ensures rapid drainage and collection of the scraped water, preventing water residue or splashing. An overflow hole 21 is provided in the water storage box 28. 2. The guide trough 213 is positioned above the gap between the conveyor belt 1 and the mounting frame, and works in conjunction with the bottom U-shaped mounting frame 214 and the triangular guide platform 215 to achieve orderly guidance and centralized recovery of excess water, preventing water from contaminating the equipment or starch milk. The rotating roller 22 driven by the motor 24 rotates synchronously with the water-absorbing layer 23, and the scraper 211 squeezes and dehydrates the water-absorbing layer 23, realizing the recycling of the water-absorbing layer 23. This eliminates the need for frequent replacement of water-absorbing components, ensuring continuous operation. By linking the rotating roller 22 of the extrusion component 3 and the dewatering component 2, the mounting block 34 drives the push plate 37 to push the water storage box 28 up and down along the lifting trough 26, achieving automatic squeezing and dehydration of pure starch milk without the need for an additional power source, reducing energy consumption. Through the elastic support and reset function of spring 32, combined with the structural design of the straight and curved surfaces at the bottom of push plate 37, water storage box 28 can automatically complete the squeezing and reset cycle, ensuring the continuity and stability of the squeezing operation and adapting to the continuous conveying rhythm of conveyor 1. The support rod 33 supports the conveyor belt of conveyor 1, preventing excessive belt deformation during squeezing, ensuring uniform squeezing force, and efficiently squeezing out free water from the starch slurry, reducing the adsorption load on the subsequent absorbent layer 23. By setting reset column 38 and reset groove 311 of L-shaped reset plate 310, automatic extension and retraction reset of push plate 37 is achieved, ensuring the reliability of the squeezing mechanism's cyclic operation. At the same time, the elastic squeezing method avoids excessive damage to starch granules, ensuring starch quality.
