Description

Technical Field

[0001] The present invention relates to the technical field of solid-liquid separation, and particularly to a solid-liquid separation device and method for treating distiller's grains feed for livestock and poultry breeding. Background Art

[0002] In the field of livestock and poultry breeding, distiller's grains, as a by-product of the brewing industry, are rich in nutrients such as protein and vitamins and are an excellent feed source. However, the moisture content of fresh distiller's grains is as high as over 60%, which can easily cause diarrhea in animals when fed directly, and the transportation and storage costs are high. The solid-liquid separation device separates the solid and liquid in the distiller's grains through physical methods (such as extrusion and centrifugation).

[0003] For example, in the patent document with the prior art publication number CN221207016U, this patent document discloses a solid-liquid separation device for feed processing, including a base. Both ends of the top of the base are provided with support columns, the top of the support columns is fixed with a separation box, a drain pipe is installed at the bottom of the side of the separation box, a separation mechanism for solid-liquid separation is installed inside the separation box, and a feeding mechanism for feeding the feed is installed at the top of the separation box. By setting the separation mechanism, using the rotating first screw rod in cooperation with the sealing plug, the feed entering the filter cylinder is extruded, and solid-liquid separation occurs due to the extrusion. The device has a simple structure and a very high separation efficiency. At the same time, by setting the feeding mechanism for feeding the feed, the feed is conveyed into the filter cylinder through the cooperation of the second screw rod and the connecting pipe, and the feeding speed can be controlled by controlling the speed of the second screw rod, which is convenient for flexible adjustment according to the processing progress and is very convenient to use.

[0004] Although the existing spiral feed inlet design improves the smoothness of material transportation through mechanical structure improvement, when processing distiller's grains materials with high moisture content, its hydrodynamic defects lead to insufficient separation efficiency of wet materials. Specifically, although the centrifugal action of the spiral blades can push the solid materials forward, it causes the liquid components to form an eddy accumulation effect in the feed inlet area. When the moisture content of the materials is too high, the thickness of the liquid film at the radial clearance of the spiral shaft will continue to increase, and finally a liquid damping layer is formed at the bottom of the feed cavity. This not only reduces the effective conveying cross-sectional area, but also increases the torque load due to the adhesion effect between the liquid medium and the metal blades, forming a vicious cycle of "water lock - overload". Therefore, the present application proposes a solid-liquid separation device and method for treating distiller's grains feed for livestock and poultry breeding. Summary of the Invention

[0009] Preferably, an auxiliary cylinder is fixedly connected to one side of the treatment box. The end of the auxiliary cylinder far from the treatment box is communicated with a discharge nozzle for discharging materials. A screen is fixedly connected inside the auxiliary cylinder. An inclined return groove with a slope structure and communicated with the liquid collection cavity is opened at the bottom of the auxiliary cylinder. One end of the rotating rod extends into the auxiliary cylinder, and a screw blade adapted to the screen is fixedly connected to the outer surface.

[0010] Preferably, the air delivery component includes a resistance plate fixedly connected inside the treatment box.

A diversion blocking plate is fixedly connected to the end of the rotating plate away from the cleaning air nozzle. A first air blocking plate is fixedly connected to the inside of the exhaust nozzle, and the diversion blocking plate is adapted to the first air blocking plate.

[0012] Preferably, a guide plate is constructed above the blocking filter screen inside the processing box. A side liquid groove communicating with the liquid collection cavity is opened inside the processing box, and one end of the guide plate extends into the side liquid groove.

[0013] Preferably, the power assembly includes a top plate fixedly connected to the top of the inclined blanking box.

[0014] Preferably, a plurality of convex strips are fixedly connected to the bottom of the material scattering plate, and a warping pressure plate is fixedly connected to one end of the material scattering plate.

[0015] The present invention also provides a solid-liquid separation method for treating distiller's grains feed for livestock and poultry breeding, including the following steps: S1. When in use, first pour the distiller's grains from the top of the inclined blanking box and process them through the material scattering plate. When the distiller's grains slide on the top of the inclined blanking box, a large amount of water will pass through the drainage groove by gravity and enter the inside of the liquid collection cavity. S2. Then start the power assembly to drive the material scattering plate to swing left and right, and continuously disperse the distiller's grains passing through its bottom. S3. Then the separation assembly operates to stir the distiller's grains in the processing box, so that the distiller's grains are dehydrated under the influence of centrifugal force and gravity. S4. At the same time, start the air pump to cooperate with the air delivery assembly to make the blocking filter screen bear force to block the distiller's grains. The liquid inside it passes through the blocking filter screen and then falls into the side liquid groove under the influence of gravity. The gas of the air pump blows towards the blocking filter screen to blow the distiller's grains on its surface off.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. When the distillers grains slide on the top of the feeding inclined box, a large amount of liquid is quickly separated by multiple drainage grooves relying on gravity, achieving preliminary dehydration, reducing the subsequent treatment pressure. The water guide grooves designed on the inclined surface guide the separated liquid to efficiently flow into the liquid collection cavity, avoiding secondary pollution caused by liquid retention. The driving bulk material plate shakes left and right to break up the lumped distillers grains, enhancing the disturbance through the convex strips to improve the liquid separation efficiency. Adjust the feeding angle of the distillers grains to prevent accumulation and ensure uniform distribution. The rotating rod drives multiple stirring inclined plates to rotate, and the distillers grains are squeezed in the arc-shaped cavity under the dual action of centrifugal force and gravity. The liquid is discharged through the gravity drainage groove to achieve efficient dehydration. The trapezoidal structure is used to hold gravel of different sizes to prevent it from entering the subsequent process and damaging the equipment or polluting the feed. The liquid and fine distillers grains are discharged through the liquid separation cavity, while the gravel is intercepted to achieve precise separation of solid-liquid and impurities. The rotating rod drives the auger blade to rotate, squeezing the distillers grains through the sieve to further dehydrate and improve the dryness of the solid feed. The separated liquid flows back to the liquid collection cavity through the inclined surface to avoid liquid residue and ensure the cleanliness inside the treatment box. The treated solid feed is centrally discharged through the discharge nozzle, facilitating collection or subsequent processing, significantly improving the separation efficiency. The trapezoidal card slot and the liquid separation cavity work together to effectively remove hard impurities such as gravel, protect the equipment and improve the feed safety. The driving motor is linked with the auger blade to achieve continuous production and reduce manual intervention.

[0017] 2. When the stirring inclined plate rotates, the distillers grains are thrown towards the resistance filter screen. The liquid passes through the resistance filter screen due to inertia and adheres to the surface of the diversion plate, and finally flows into the side liquid tank. This process utilizes the dual action of inertia force and filtration to significantly improve the liquid separation efficiency, especially for viscous distillers grains. When the resistance filter screen is impacted and moved by the distillers grains, it drives the rotating plate to rotate. The diversion resistance plate and the first air resistance plate cooperate to switch the air flow of the air pump from the bottom exhaust nozzle to the top cleaning air nozzle. The bottom air flow is used to blow away the distillers grains, and the top air flow blows back and purges the resistance filter screen to prevent the distillers grains from adhering and blocking the mesh holes, achieving self-adaptive cleaning. The rotation of the stirring inclined plate not only provides centrifugal force but also throws the distillers grains towards the resistance filter screen, and the air flow of the air pump synchronously blows the distillers grains, forming a composite separation mode of centrifugal force + air flow impact, improving the separation efficiency. The separated liquid is guided to the side liquid tank through the diversion plate and is connected to the liquid collection cavity to ensure unified collection of the liquid and avoid secondary treatment. The two-way air flow of the air pump combined with the vibration of the resistance filter screen realizes online self-cleaning and reduces the frequency of shutdown maintenance.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1: Please refer to Figure 1 , Figure 2 and Figure 3, the present invention provides a technical solution: a solid-liquid separation device for treating distiller's grains feed in livestock breeding, including a feeding inclined box 100 and a liquid collection cavity 104 opened inside it. A plurality of drainage grooves 102 for liquid to pass through are opened at the top of the feeding inclined box 100, and a water guide groove 103 with an inclined surface is opened inside the feeding inclined box 100. Side support plates 101 for supporting the feeding inclined box 100 are fixedly connected to both sides of the feeding inclined box 100. By setting the drainage grooves 102, a large amount of liquid can be separated by gravity during the preliminary treatment of distiller's grains. The liquid collection cavity 104 can collect the liquid, and the water guide groove 103 allows the liquid to smoothly enter the inside of the liquid collection cavity 104.

[0022] It further includes a treatment box 200, which is fixedly connected to one end of the feeding inclined box 100 and is communicated with the feeding inclined box 100. A rotating rod 204 is arranged inside the treatment box 200, and a separation component for dehydrating the distiller's grains is arranged on the outer surface of the rotating rod 204. The separation component includes a plurality of stirring inclined plates 206 fixedly connected to the outer surface of the rotating rod 204. A driving motor 203 for driving the rotating rod 204 to rotate is fixedly connected to one side of the treatment box 200. An arc-shaped cavity 213 adapted to the plurality of stirring inclined plates 206 is opened inside the treatment box 200. A gravity discharge groove 212 communicated with the liquid collection cavity 104 is opened at the bottom of the arc-shaped cavity 213. A separation mechanism for collecting gravel in the distiller's grains is arranged inside each of the plurality of stirring inclined plates 206. By setting the cooperation of the plurality of stirring inclined plates 206 and the arc-shaped cavity 213, the dehydration of the distiller's grains can be realized, and the distiller's grains are discharged through the gravity discharge groove 212 by stirring, further realizing centrifugal dehydration. The stirring inclined plates 206 are constructed as inclined surfaces to convey the distiller's grains while dehydrating the distiller's grains. The separation mechanism can effectively separate the gravel in the distiller's grains.

[0023] Please refer to Figure 6 , Figure 7 and Figure 8 , wherein, the separation mechanism includes a liquid separation cavity 208 opened inside each of the plurality of stirring inclined plates 206. Trapezoidal card slots 207 communicated with the outside are opened at the tops of the plurality of liquid separation cavities 208. The trapezoidal card slots 207 are constructed as trapezoids for fixing gravel of different sizes. Liquid discharge nozzles 209 communicated with the outside are opened at the bottoms of the plurality of liquid separation cavities 208, and the liquid discharge nozzles 209 are used for discharging the distiller's grains. By setting the trapezoidal card slots 207, the gravel can be clamped into them, and the distiller's grains and the separated liquid can pass through the liquid separation cavity 208 and be discharged through the liquid discharge nozzles 209. The trapezoidal card slots 207 will not clamp the distiller's grains, thus realizing the separation of gravel and distiller's grains.

[0024] Please refer to Figure 2 , Figure 4 and Figure 5, Further, one side of the processing box 200 is fixedly connected with an auxiliary cylinder 201. The end of the auxiliary cylinder 201 far away from the processing box 200 is communicated with a discharge nozzle 202 for discharging materials. A screen 210 is fixedly connected inside the auxiliary cylinder 201. An inclined return groove 211 with an inclined surface structure and communicated with the liquid collection cavity 104 is arranged at the bottom of the auxiliary cylinder 201. One end of the rotating rod 204 extends into the auxiliary cylinder 201, and a screw blade 205 adapted to the screen 210 is fixedly connected to the outer surface thereof. By setting the cooperation of the screw blade 205 and the screen 210, the alcohol can be further processed. The rotation of the screw blade 205 realizes the transportation of the distillers grains and at the same time extrudes them, so that the solid-liquid separation passes through the screen 210 and returns to the inside of the liquid collection cavity 104 through the inclined return groove 211 for collection. Subsequently, the solid is discharged through the discharge nozzle 202.

[0025] Please refer to Figure 1 , Figure 11 and Figure 12 , It also includes a material spreading plate 400, which is arranged at the top of the inclined feeding box 100 for disturbing the flow of the distillers grains. A power assembly for driving the material spreading plate 400 to vibrate left and right is arranged at the top of the inclined feeding box 100. The power assembly includes a top plate 402 fixedly connected to the top of the inclined feeding box 100. A motor 403 is fixedly connected to the top of the top plate 402, and a deflecting rod 404 is fixedly connected to the output end of the motor 403. A straight groove plate 405 for the deflecting rod 404 to abut against is fixedly connected to the top of the material spreading plate 400. Positioning sliders 401 slidably connected to the inclined feeding box 100 are fixedly connected to both sides of the material spreading plate 400. A plurality of convex strips 407 are fixedly connected to the bottom of the material spreading plate 400. A warping pressure plate 406 is fixedly connected to one end of the material spreading plate 400. By setting the cooperation of the deflecting rod 404 and the straight groove plate 405, the material spreading plate 400 can be continuously driven to vibrate left and right, so as to preprocess the distillers grains, thereby dispersing the distillers grains bonded together and improving the liquid separation effect. The setting of the warping pressure plate 406 can increase the inlet angle of the distillers grains, and the convex strips 407 can improve the dispersing effect.

[0026] Specifically, when in use, first pour distillers grains from the top of the feeding inclined box 100, and process them through the material spreading plate 400. When the distillers grains slide on the top of the feeding inclined box 100, a large amount of moisture will pass through the drainage grooves 102 by gravity and enter the interior of the liquid collecting cavity 104 through the water guiding groove 103. Subsequently, continuously turn on the motor 403 to drive the biasing rod 404 to rotate, causing it to continuously slide inside the straight groove plate 405, thereby driving the material spreading plate 400 to swing left and right, and then driving the convex strips 407 to continuously squeeze the distillers grains passing through its bottom. At the same time, move left and right to break up the distillers grains. At the same time, turn on the driving motor 203 to drive the rotating rod 204 to drive a plurality of stirring inclined plates 206 to rotate, thereby driving the distillers grains falling into the arc-shaped cavity 213 to be stirred, so that the distillers grains are dehydrated under the influence of centrifugal force and gravity. The liquid will be discharged into the interior of the liquid collecting cavity 104 through the gravity discharge groove 212. The continuous stirring of the stirring inclined plates 206 conveys the distillers grains. At the same time, the gravel in the distillers grains will be caught in the trapezoidal card slots 207 under the influence of gravity. At the same time, part of the liquid will also pass through the liquid separation cavity 208 and be discharged through the liquid separation nozzle 209 to collect and separate the gravel. At the same time, the distillers grains continuously conveyed in the stirring inclined plates 206 will enter the sieve 210, so that the auger blades 205 squeeze the distillers grains to further squeeze and separate the liquid. The separated liquid will flow back to the interior of the liquid collecting cavity 104 through the inclined return groove 211.

[0027] In summary, when the distillers grains slide on the top of the feeding inclined box 100, a large amount of liquid is quickly separated by multiple drainage grooves 102 by gravity, achieving preliminary dehydration, reducing the subsequent processing pressure. The water guiding groove 103 with an inclined surface design guides the separated liquid to efficiently flow into the liquid collecting cavity 104, avoiding secondary pollution caused by liquid retention. The material spreading plate 400 is driven to shake left and right to break up the agglomerated distillers grains, enhancing the disturbance through the convex strips 407, improving the liquid separation efficiency, adjusting the feeding angle of the distillers grains, preventing accumulation, and ensuring uniform distribution. The rotating rod 204 drives a plurality of stirring inclined plates 206 to rotate, squeezing the distillers grains in the arc-shaped cavity 213 under the dual action of centrifugal force + gravity. The liquid is discharged through the gravity discharge groove 212 to achieve efficient dehydration. The trapezoidal structure is used to catch gravel of different sizes to prevent it from entering the subsequent process and damaging the equipment or polluting the feed. The liquid and fine distillers grains are discharged through the liquid separation cavity 208, while the gravel is intercepted, achieving precise separation of solid-liquid and impurities. The rotating rod 204 drives the auger blades 205 to rotate, squeezing the distillers grains through the sieve 210 to further dehydrate and improve the dryness of the solid feed. The separated liquid flows back to the liquid collecting cavity 104 through the inclined surface to avoid liquid residue and ensure the cleanliness inside the processing box 200. The processed solid feed is centrally discharged through the discharge nozzle 202, facilitating collection or subsequent processing, significantly improving the separation efficiency. The trapezoidal card slots 207 and the liquid separation cavity 208 work together to effectively remove hard impurities such as gravel, protect the equipment and improve the feed safety. The driving motor 203 and the auger blades 205 are linked to achieve continuous production and reduce manual intervention.

[0028] Example 2: Please refer to Figure 3 、 Figure 9 and Figure 10 , the present invention also provides a technical solution. The difference from the technical solution of Example 1 is: a solid-liquid separation device for treating distiller's grains feed for livestock and poultry farming, further comprising an air pump 300, which is fixedly connected to the top of the treatment tank 200. A resistance filter screen 302 that cooperates with the separation component is rotatably connected inside the treatment tank 200. And an air delivery component for treating the distiller's grains on the surface of the resistance filter screen 302 is arranged at the output end of the air pump 300. By setting the air delivery component, the surface of the resistance filter screen 302 can be cleaned. Under the action of the stirring inclined plate 206, the distiller's grains can be thrown up and thrown onto the surface of the resistance filter screen 302, so that the liquid in the distiller's grains is separated under the influence of inertia.

[0029] Furthermore, the air delivery component includes a resistance plate 301 fixedly connected inside the treatment tank 200. An air delivery groove 305 communicating with the output end of the air pump 300 is opened inside the resistance plate 301. An exhaust nozzle 306 for discharging gas is opened inside the resistance plate 301. A positioning plate 311 for limiting the resistance filter screen 302 is fixedly connected to one side of the resistance plate 301. A direction-changing mechanism for changing the gas flow direction is arranged inside the resistance plate 301. By setting the exhaust nozzle 306, the gas generated by the air pump 300 can be discharged below the resistance filter screen 302, so as to blow the distiller's grains, so that the distiller's grains are blown by the gas when they are about to be thrown onto the resistance filter screen 302, thereby further improving the subsequent solid-liquid separation.

[0030] Among them, the direction-changing mechanism includes a rotating plate 308 rotatably connected to one side of the resistance plate 301. One end of the rotating plate 308 is fixedly connected with a cleaning air nozzle 309 that can contact the resistance filter screen 302. A flow-dividing resistance plate 310 is fixedly connected to the end of the rotating plate 308 away from the cleaning air nozzle 309. A first air-blocking plate 307 is fixedly connected inside the exhaust nozzle 306, and the flow-dividing resistance plate 310 is adapted to the first air-blocking plate 307. An opening is opened at the top of the flow-dividing resistance plate 310 for passing through the inside of the rotating plate 308 and discharging to the top of the resistance filter screen 302 from the bottom of the cleaning air nozzle 309. By setting the cooperation of the flow-dividing resistance plate 310 and the first air-blocking plate 307, the rotating plate 308 can be driven to rotate while the distiller's grains are thrown onto the resistance filter screen 302, so that the flow-dividing resistance plate 310 contacts the first air-blocking plate 307 to block the exhaust nozzle 306, so that the gas generated by the air pump 300 passes through the flow-dividing resistance plate 310 and is discharged from the cleaning air nozzle 309, so as to blow up from above the resistance filter screen 302 and blow off the distiller's grains adhering to the bottom of the resistance filter screen 302.

[0031] Furthermore, a flow guide plate 303 is constructed inside the processing tank 200 and above the resistance filter screen 302. A side liquid tank 304 communicating with the liquid collection cavity 104 is opened inside the processing tank 200, and one end of the flow guide plate 303 extends into the side liquid tank 304. By setting the flow guide plate 303, the liquid separated at the bottom of the resistance filter screen 302 can be guided. When the distiller's grains touch the resistance filter screen 302, the liquid will continue to move due to inertia and will be thrown onto the surface of the flow guide plate 303, and then adhere to the surface of the flow guide plate 303 and fall into the side liquid tank 304 by gravity.

[0032] Specifically, under the action of the stirring inclined plate 206, the distiller's grains will be subjected to centrifugal force and be thrown towards the resistance filter screen 302, so that the resistance filter screen 302 blocks the distiller's grains and the liquid inside it passes through the resistance filter screen 302 and touches the surface of the flow guide plate 303, and then falls into the side liquid tank 304 under gravity. Continuously start the air pump 300 to pump air into the air delivery tank 305, and the gas will be discharged through the exhaust nozzle 306 and blown towards the bottom of the resistance filter screen 302 to blow-dry the distiller's grains and improve the efficiency of solid-liquid separation. As the resistance filter screen 302 moves under force, it will touch the cleaning air nozzle 309 and drive the rotating plate 308 to rotate, so that the shunt resistance plate 310 presses down and cooperates with the first air blocking plate 307 to block the exhaust nozzle 306, so that the gas pumped out of the air pump 300 passes through the shunt resistance plate 310 and is discharged through the cleaning air nozzle 309, blowing towards the top of the resistance filter screen 302 so that the distiller's grains attached to the bottom of the resistance filter screen 302 are forced to move down and return to the inside of the arc-shaped cavity 213.

[0033] In summary, when the stirring inclined plate 206 rotates, the distiller's grains are thrown towards the resistance filter screen 302, and the liquid passes through the resistance filter screen 302 due to inertia and adheres to the surface of the flow guide plate 303, and finally flows into the side liquid tank 304. This process utilizes the dual effects of inertial force + filtration, significantly improving the liquid separation efficiency, especially for viscous distiller's grains. When the resistance filter screen 302 is impacted and moved by the distiller's grains, it drives the rotating plate 308 to rotate. The shunt resistance plate 310 and the first air blocking plate 307 cooperate to switch the air flow of the air pump 300 from the bottom exhaust nozzle 306 to the top cleaning air nozzle 309. The bottom air flow is used to blow away the distiller's grains, and the top air flow blows the resistance filter screen 302 in the reverse direction to prevent the distiller's grains from adhering and blocking the mesh holes, realizing self-adaptive cleaning. The rotation of the stirring inclined plate 206 not only provides centrifugal force but also throws the distiller's grains towards the resistance filter screen 302, and the air flow of the air pump 300 synchronously blows the distiller's grains, forming a composite separation mode of centrifugal force + air flow impact, improving the separation efficiency. The separated liquid is guided to the side liquid tank 304 through the flow guide plate 303 and communicates with the liquid collection cavity 104 to ensure unified collection of the liquid and avoid secondary treatment. The two-way air flow of the air pump 300 is combined with the vibration of the resistance filter screen 302 to realize online self-cleaning and reduce the frequency of shutdown maintenance.

[0034] Example 3: Please refer to Figures 1 to 12, the present invention also provides a technical solution, which is different from the technical solution of Embodiment 1: a solid-liquid separation method for treating distiller's grains feed for livestock and poultry breeding, including the following steps: S1. When in use, first pour the distiller's grains from the top of the feeding inclined box 100 and process them through the material scattering plate 400. When the distiller's grains slide on the top of the feeding inclined box 100, a large amount of water will pass through the drainage groove 102 under the influence of gravity and enter the inside of the liquid collecting cavity 104 through the water guiding groove 103; S2. Subsequently, continuously start the motor 403 to drive the biasing rod 404 to rotate, so that it continuously slides inside the straight groove plate 405, thereby driving the material scattering plate 400 to swing left and right, and then driving the convex strip 407 to continuously squeeze the distiller's grains passing through its bottom, and at the same time move left and right to disperse the distiller's grains; S3. At the same time, start the driving motor 203 to drive the rotating rod 204 to drive a plurality of stirring inclined plates 206 to rotate, thereby driving the distiller's grains falling into the arc-shaped cavity 213 to be stirred, so that the distiller's grains are dehydrated under the influence of centrifugal force and gravity. The liquid will be discharged into the inside of the liquid collecting cavity 104 through the gravity discharge groove 212, and the stirring inclined plates 206 continuously stir and convey the distiller's grains. At the same time, the gravel in the distiller's grains will be stuck in the trapezoidal card slot 207 under the influence of gravity. At the same time, part of the liquid will also pass through the liquid separation cavity 208 and pass through the liquid separation nozzle 209 to be discharged, so as to collect and separate the gravel. At the same time, the distiller's grains continuously conveyed in the stirring inclined plates 206 will enter the screen 210, so that the auger blades 205 squeeze the distiller's grains to further squeeze and separate the liquid, and the separated liquid will flow back to the inside of the liquid collecting cavity 104 through the inclined return groove 211; S4. At the same time, under the action of the stirring inclined plates 206, the distiller's grains will be thrown towards the resistance filter screen 302 under the influence of centrifugal force, so that the resistance filter screen 302 blocks the distiller's grains, and the liquid inside it passes through the resistance filter screen 302 and touches the surface of the guide plate 303, and then falls into the side liquid groove 304 under the influence of gravity. Continuously start the air pump 300 to pump air into the air conveying groove 305, and the gas will be discharged through the exhaust nozzle 306 and blown towards the bottom of the resistance filter screen 302 to blow-dry the distiller's grains and improve the efficiency of solid-liquid separation. As the resistance filter screen 302 moves under force, it will touch the cleaning air nozzle 309 and drive the rotating plate 308 to rotate, so that the shunt resistance plate 310 is pressed down to cooperate with the first air blocking plate 307 to block the exhaust nozzle 306, so that the gas pumped out of the air pump 300 passes through the shunt resistance plate 310 and is discharged through the cleaning air nozzle 309, and is blown towards the top of the resistance filter screen 302, so that the distiller's grains attached to the bottom of the resistance filter screen 302 are forced to move down and return to the inside of the arc-shaped cavity 213.
