Description

Technical Field

[0001] The present invention relates to the technical field of solid-liquid separation, and in particular to a solid-liquid separation device and method for processing distiller's grains feed for animal husbandry. Background Art

[0002] In the livestock farming sector, distiller's grains, a byproduct of the brewing industry, are rich in nutrients such as protein and vitamins, making them a high-quality feed source. However, fresh distiller's grains have a moisture content exceeding 60%, making direct feeding them prone to diarrhea and high transportation and storage costs. Solid-liquid separation devices use physical methods (such as extrusion and centrifugation) to separate the solids from the liquid in the distiller's grains.

[0003] For example, the patent document with the prior art announcement number CN221207016U discloses a solid-liquid separation device for feed processing, comprising a base, support columns installed at both ends of the top of the base, a separation box fixed on the top of the support column, a drain pipe installed at the bottom of the side of the separation box, a separation mechanism for solid-liquid separation installed inside the separation box, and a feeding mechanism for feed delivery installed on the top of the separation box. By setting up a separation mechanism, a rotating first screw is used in conjunction with a sealing plug to squeeze the feed entering the filter cartridge, and the feed is separated into solid and liquid due to the squeezing. The device has a simple structure and a very high separation efficiency. At the same time, the feed is delivered by setting up a feeding mechanism, and the feed is transported to the filter cartridge by the cooperation of the second screw and the connecting pipe. The feeding speed can be controlled by controlling the speed of the second screw, which is convenient for flexible adjustment according to the processing progress and is very convenient to use.

[0004] Although the existing spiral feed port design has improved the smoothness of material transportation through mechanical structure improvements, its fluid dynamics defects lead to insufficient wet material separation efficiency when processing distiller's grains materials with high moisture content. Specifically, although the centrifugal action of the spiral blades can propel solid materials forward, it causes the liquid components to form a vortex accumulation effect in the feed port area. When the moisture content of the material is too high, the thickness of the liquid film at the radial gap of the spiral shaft will continue to grow, and eventually a liquid damping layer will form at the bottom of the feed chamber. This not only causes the effective conveying cross-sectional area to decrease, but also due to the adhesion effect between the liquid medium and the metal blades, the torque load increases, forming a vicious cycle of "water lock-overload". To this end, the present application proposes a solid-liquid separation device and method for treating distiller's grains feed for animal husbandry. Summary of the Invention

[0018] The present invention also provides a solid-liquid separation method for treating distiller's grains feed for animal husbandry, comprising the following steps:

[0019] S1. When in use, the lees are first poured into the top of the discharging inclined box and processed through the bulk plate. As the lees slide on the top of the discharging inclined box, a large amount of water will flow through the drainage trough into the liquid collecting chamber under the force of gravity;

[0020] S2. Then, the power assembly is turned on to drive the bulk plate to swing left and right, continuously breaking up the lees passing through the bottom of the plate;

[0021] S3, then the separation component operates to stir the lees in the treatment tank, so that the lees are dehydrated due to the influence of centrifugal force and gravity;

[0022] S4. Simultaneously start the air pump and the air delivery assembly to apply force to the filter screen to block the lees. The liquid inside the filter screen passes through the filter screen and then falls into the side liquid tank due to gravity. The gas from the air pump blows toward the filter screen, and the blowing of air on the filter screen separates the lees on its surface.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. When the lees slide on the top of the discharging inclined box, a large amount of liquid is quickly separated by gravity through multiple drainage grooves, achieving initial dehydration and reducing the pressure of subsequent processing. The inclined water guide groove guides the separated liquid to flow efficiently into the liquid collecting chamber to avoid secondary pollution caused by liquid retention. The bulk plate is driven to shake left and right to break up the agglomerated lees. The convex strips enhance the disturbance and improve the liquid separation efficiency. The entry angle of the lees is adjusted to prevent accumulation and ensure uniform distribution. The rotating rod drives multiple stirring inclined plates to rotate, and the lees are squeezed by the dual action of centrifugal force and gravity in the arc cavity. The liquid is discharged through the gravity discharge groove to achieve efficient dehydration. The trapezoidal structure is used to clamp gravel of different sizes to prevent it from entering the back The continuous process will not damage the equipment or contaminate the feed. The liquid and finely crushed lees are discharged through the liquid separation chamber, while the gravel is intercepted, realizing the precise separation of solid, liquid and impurities. The rotating rod drives the auger blades to rotate, squeezing the lees through the screen for further dehydration, thereby improving the dryness of the solid feed. The separated liquid flows back to the liquid collecting chamber through the inclined surface to avoid liquid residue and ensure the cleanliness of the inside of the processing box. The processed solid feed is discharged centrally through the discharge nozzle for easy collection or subsequent processing, which significantly improves the separation efficiency. The trapezoidal card slot works synergistically with the liquid separation chamber to effectively remove hard impurities such as gravel, protect the equipment and improve the safety of the feed. The drive motor is linked with the auger blades to realize continuous production and reduce manual intervention.

[0025] 2. When the stirring inclined plate rotates, the lees are thrown toward the filter screen. Due to inertia, the liquid passes through the filter screen and adheres to the surface of the guide plate, and finally flows into the side liquid tank. This process utilizes the dual effects of inertia and filtration to significantly improve the liquid separation efficiency, especially for viscous lees. When the filter screen is moved by the impact of the lees, it drives the rotating plate to rotate. The diverter baffle cooperates with the first air baffle to switch the air pump airflow from the bottom exhaust nozzle to the top cleaning air nozzle. The bottom airflow is used to blow away the lees, and the top airflow blows the filter screen in the opposite direction to prevent the lees from adhering to the filter screen and clogging the mesh, thereby achieving adaptive cleaning. The rotation of the stirring inclined plate not only provides centrifugal force, but also throws the lees toward the filter screen, while the airflow of the air pump simultaneously blows the lees, forming a composite separation mode of centrifugal force and airflow impact, which improves the separation efficiency. The separated liquid is guided to the side liquid tank through the guide plate and connected to the liquid collecting chamber to ensure uniform collection of the liquid and avoid secondary treatment. The two-way airflow of the air pump is combined with the vibration of the filter screen to achieve online self-cleaning and reduce the frequency of downtime and maintenance.

By arranging multiple stirring inclined plates 206 in cooperation with the arc-shaped cavity 213, the lees can be dehydrated, stirred and discharged through the gravity discharge chute 212, further realizing centrifugal dehydration. The stirring inclined plates 206 are constructed as an inclined surface, which can transport the lees while dehydrating the lees, and the separation mechanism can effectively separate the gravel in the lees.

[0043] See also Figure 2 、 Figure 4 as well as Figure 5 Furthermore, an auxiliary cylinder 201 is fixedly connected to one side of the processing box 200, and the end of the auxiliary cylinder 201 away from the processing box 200 is connected to a discharge nozzle 202 for discharging. A screen 210 is fixedly connected to the interior of the auxiliary cylinder 201, and an inclined reflux groove 211 with a slope structure and connected to the liquid collecting chamber 104 is provided at the bottom of the auxiliary cylinder 201. One end of the rotating rod 204 extends to the interior of the auxiliary cylinder 201 and the outer surface is fixedly connected to an auger blade 205 adapted to the screen 210. By arranging the auger blade 205 and the screen 210, the alcohol can be further processed. The rotation of the auger blade 205 can realize the transportation and squeezing of the lees at the same time, so that the solid and liquid are separated, pass through the screen 210 and pass through the inclined reflux groove 211 to return to the interior of the liquid collecting chamber 104 for collection, and then the solid is discharged through the discharge nozzle 202.

[0044] See also Figure 1 、 Figure 11 as well as Figure 12 , also includes a bulk plate 400, which is arranged on the top of the unloading inclined box 100 for disturbing the flow of wine lees, and a power component for driving the bulk plate 400 to shake left and right is provided on the top of the unloading inclined box 100, and the power component includes a top plate 402 fixedly connected to the top of the unloading inclined box 100, a motor 403 is fixedly connected to the top of the top plate 402, and a deflection rod 404 is fixedly connected to the output end of the motor 403, and a straight groove plate 405 for the deflection rod 404 to resist is fixedly connected to the top of the bulk plate 400, and both sides of the bulk plate 400 are fixedly connected to the top of the unloading inclined box 100. The sides are fixedly connected with a positioning slider 401 that is slidably connected to the unloading inclined box 100, the bottom of the bulk plate 400 is fixedly connected with a plurality of convex strips 407, and one end of the bulk plate 400 is fixedly connected with a tilting pressure plate 406. By setting the deflection rod 404 and the straight groove plate 405, the bulk plate 400 can be continuously driven to shake left and right, so as to pre-treat the wine dregs, thereby breaking up the wine dregs that are stuck together and improving the separation effect of the liquid. The setting of the tilting pressure plate 406 can increase the entry angle of the wine dregs, and the convex strips 407 can improve the breaking effect.

[0045] Specifically, when in use, the wine lees are first poured into the top of the discharge inclined box 100 and processed through the bulk plate 400. When the wine lees slide on the top of the discharge inclined box 100, a large amount of water will be separated by gravity through the drainage groove 102 and enter the interior of the liquid collecting chamber 104 through the water guide groove 103. Then, the motor 403 is continuously turned on to drive the deflection rod 404 to rotate so that it continuously slides inside the straight groove plate 405, thereby driving the bulk plate 400 to swing left and right, and then driving the convex strips 407 to continuously squeeze the wine lees passing through its bottom. At the same time, the left and right movement will break up the wine lees. At the same time, the drive motor 203 is turned on to drive the rotating rod 204 to drive multiple stirring inclined plates 206 to rotate, thereby driving The wine lees falling into the arc-shaped cavity 213 are stirred, so that the wine lees are dehydrated by the influence of centrifugal force and gravity, and the liquid will be discharged to the interior of the liquid collecting chamber 104 through the gravity discharge groove 212, and the stirring inclined plate 206 continuously stirs and transports the wine lees. At the same time, the gravel in the wine lees will be affected by gravity and stuck in the trapezoidal groove 207. At the same time, part of the liquid will also be discharged through the liquid separation chamber 208 through the liquid separation nozzle 209, and the gravel will be collected and separated. At the same time, the wine lees are continuously transported in the stirring inclined plate 206 and will enter the screen 210, so that the auger blades 205 squeeze the wine lees and further squeeze the liquid to separate the liquid. The separated liquid will flow back to the interior of the liquid collecting chamber 104 through the inclined reflux groove 211.

[0046] In summary, when the lees slide on the top of the discharging inclined box 100, a large amount of liquid is quickly separated by gravity through multiple drainage grooves 102, achieving preliminary dehydration and reducing the pressure of subsequent processing. The inclined water guide groove 103 guides the separated liquid to flow into the liquid collecting chamber 104 efficiently to avoid secondary pollution caused by liquid retention, and drives the bulk plate 400 to shake left and right to break up the agglomerated lees. The disturbance is enhanced by the convex strips 407 to improve the liquid separation efficiency, adjust the entry angle of the lees, prevent accumulation, and ensure uniform distribution. The rotating rod 204 drives multiple stirring inclined plates 206 to rotate, and the lees are squeezed by the dual action of centrifugal force + gravity in the arc cavity 213. The liquid is discharged through the gravity discharge groove 212 to achieve efficient dehydration, and the trapezoidal structure is used to clamp gravel of different sizes to prevent it from entering the subsequent The process damages equipment or contaminates feed. Liquid and finely crushed lees are discharged through the liquid separation chamber 208, while gravel is intercepted, achieving precise separation of solid, liquid and impurities. The rotating rod 204 drives the auger blade 205 to rotate, squeezing the lees through the screen 210 for further dehydration, thereby improving the dryness of the solid feed. The separated liquid flows back to the liquid collecting chamber 104 through the inclined surface to avoid liquid residue and ensure the cleanliness of the interior of the processing box 200. The processed solid feed is discharged centrally through the discharge nozzle 202 for easy collection or subsequent processing, which significantly improves the separation efficiency. The trapezoidal slot 207 works in conjunction with the liquid separation chamber 208 to effectively remove hard impurities such as gravel, protect equipment and improve feed safety. The drive motor 203 is linked with the auger blade 205 to achieve continuous production and reduce manual intervention.

[0047] Example 2: Please refer to Figure 3 、 Figure 9 as well as Figure 10 The present invention also provides a technical solution, which is different from the technical solution of embodiment 1: a solid-liquid separation device for processing distiller's grains feed for animal husbandry, further comprising an air pump 300, which is fixedly connected to the top of the processing box 200, and the interior of the processing box 200 is rotatably connected to a filter screen 302 that cooperates with the separation component, and the output end of the air pump 300 is provided with an air supply component for processing distiller's grains on the surface of the filter screen 302. By setting up the air supply component, the surface of the filter screen 302 can be cleaned, and under the action of the stirring inclined plate 206, the distiller's grains can be thrown up and thrown to the surface of the filter screen 302, so that the liquid in the distiller's grains is separated by inertia.

[0048] Furthermore, the gas delivery component includes a baffle 301 fixedly connected to the inside of the processing box 200, and a gas delivery groove 305 connected to the output end of the air pump 300 is provided inside the baffle 301, and an exhaust nozzle 306 for gas discharge is provided inside the baffle 301. A positioning plate 311 for limiting the filter screen 302 is fixedly connected to one side of the baffle 301, and a changing mechanism for changing the direction of gas flow is provided inside the baffle 301. By setting the exhaust nozzle 306, the gas generated by the air pump 300 can be discharged to the bottom of the filter screen 302, thereby blowing the wine lees, so that the wine lees are blown by the gas when they are about to be thrown to the filter screen 302, thereby further improving the subsequent solid-liquid separation.

[0049] The direction-changing mechanism includes a rotating plate 308 rotatably connected to one side of the baffle 301, and one end of the rotating plate 308 is fixedly connected to a cleaning air nozzle 309 that can interfere with the filter screen 302, and the end of the rotating plate 308 away from the cleaning air nozzle 309 is fixedly connected to a diverter baffle 310, and the interior of the exhaust nozzle 306 is fixedly connected to the first baffle plate 307, and the diverter baffle 310 is adapted to the first baffle plate 307, and an opening is opened on the top of the diverter baffle 310 for passing through the interior of the rotating plate 308 from the cleaning air nozzle 309. The gas is discharged from the bottom of the gas regulating nozzle 309 to the top of the filter screen 302. By setting the diverter baffle 310 and the first gas blocking plate 307, the rotating plate 308 can be driven to rotate while the lees are thrown to the filter screen 302, so that the diverter baffle 310 and the first gas blocking plate 307 collide with each other to block the exhaust nozzle 306, so that the gas generated by the air pump 300 passes through the diverter baffle 310 and is discharged from the cleaning gas nozzle 309, thereby blowing up the top of the filter screen 302 and blowing down the lees adhering to the bottom of the filter screen 302.

[0050] Furthermore, a guide plate 303 is constructed inside the processing box 200 and above the filter screen 302. A side liquid trough 304 connected to the liquid collecting chamber 104 is opened inside the processing box 200, and one end of the guide plate 303 extends to the inside of the side liquid trough 304. By setting the guide plate 303, the liquid separated at the bottom of the filter screen 302 can be guided. When the lees hit the filter screen 302, the liquid will continue to move due to inertia and will be thrown to the surface of the guide plate 303, and then adhere to the surface of the guide plate 303 and fall into the inside of the side liquid trough 304 by gravity.

[0051] Specifically, under the action of the stirring inclined plate 206, the wine lees will be subjected to centrifugal force and thrown toward the filter screen 302, so that the filter screen 302 is forced to block the wine lees, and the liquid inside the filter screen 302 passes through the filter screen 302 and hits the surface of the guide plate 303, and then falls into the side liquid tank 304 under gravity. The air pump 300 is continuously turned on to continuously pump air into the air delivery tank 305, and the gas will be discharged through the exhaust nozzle 306 and blown to the bottom of the filter screen 302, thereby drying the wine lees and improving the solidification. The efficiency of liquid separation is improved, and as the filter screen 302 is forced to move, it will resist the cleaning air nozzle 309 and drive the rotating plate 308 to rotate, so that the diverter baffle 310 is pressed down and cooperates with the first air baffle plate 307 to block the exhaust nozzle 306, so that the gas pumped out of the air pump 300 passes through the diverter baffle 310 and is discharged through the cleaning air nozzle 309, blowing to the top of the filter screen 302, so that the lees attached to the bottom of the filter screen 302 are forced to move down and back to the inside of the arc cavity 213.

[0052] In summary, when the stirring inclined plate 206 rotates, the lees are thrown toward the filter screen 302 , and the liquid passes through the filter screen 302 due to inertia and adheres to the surface of the guide plate 303 , and finally flows into the side liquid tank 304 . This process utilizes the dual effects of inertia force + filtration to significantly improve the liquid separation efficiency, especially for viscous lees. When the filter screen 302 is impacted and moved by the lees, it drives the rotating plate 308 to rotate, and the diverter baffle 310 cooperates with the first air baffle plate 307 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 lees, and the top air flow reversely sweeps the filter screen 302 to prevent the lees from adhering to and clogging the mesh, thereby achieving adaptive cleaning. The rotation of the stirring inclined plate 206 not only provides centrifugal force, but also throws the lees toward the filter screen 302, while the air flow of the air pump 300 simultaneously blows the lees, forming a composite separation mode of centrifugal force + air flow impact, which improves the separation efficiency. The separated liquid is guided to the side liquid tank 304 through the guide plate 303 and connected to the liquid collecting chamber 104, ensuring unified collection of the liquid and avoiding secondary treatment. The two-way airflow of the air pump 300 is combined with the vibration of the filter screen 302 to achieve online self-cleaning and reduce the frequency of downtime maintenance.

[0053] Example 3: Please refer to Figures 1 to 12The 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 animal husbandry, comprising the following steps:

[0054] S1. During use, the lees are first poured into the top of the discharging slant box 100 and processed through the bulk plate 400. As the lees slide on the top of the discharging slant box 100, a large amount of water is separated by gravity through the drainage groove 102 and enters the interior of the liquid collecting chamber 104 through the water guide groove 103;

[0055] S2, then continuously turning on the motor 403 to drive the deflection rod 404 to rotate so that it continuously slides inside the straight groove plate 405, thereby driving the bulk plate 400 to swing left and right, and then driving the ridges 407 to continuously squeeze the lees passing through the bottom thereof, while moving left and right to break up the lees;

[0056] S3, at the same time, the driving motor 203 is turned on to drive the rotating rod 204 and drive the multiple stirring inclined plates 206 to rotate, thereby driving the wine lees falling into the arc-shaped cavity 213 to be stirred, so that the wine lees are dehydrated by the influence of centrifugal force and gravity, and the liquid will be discharged to the interior of the liquid collecting chamber 104 through the gravity discharge groove 212, and the stirring inclined plates 206 are constantly stirring to transport the wine lees. At the same time, the gravel in the wine lees will be affected by gravity and stuck in the trapezoidal groove 207. At the same time, part of the liquid will also be discharged through the liquid separation chamber 208 through the liquid separation nozzle 209, and the gravel will be collected and separated. At the same time, the wine lees are continuously transported in the stirring inclined plates 206 to enter the screen 210, so that the auger blades 205 squeeze the wine lees and further squeeze the liquid to separate the liquid. The separated liquid will flow back to the interior of the liquid collecting chamber 104 through the inclined reflux groove 211;

[0057] S4. At the same time, under the action of the stirring inclined plate 206, the lees will be subjected to centrifugal force and thrown towards the filter screen 302, so that the filter screen 302 is forced to block the lees and the liquid inside it passes through the filter screen 302 and hits the surface of the guide plate 303, and then falls into the side liquid tank 304 under gravity. The air pump 300 is continuously turned on to continuously pump air into the air delivery tank 305. The gas will be discharged through the exhaust nozzle 306 and blown to the bottom of the filter screen 302, thereby drying the lees and improving the solidification. The efficiency of liquid separation is improved, and as the filter screen 302 is forced to move, it will resist the cleaning air nozzle 309 and drive the rotating plate 308 to rotate, so that the diverter baffle 310 is pressed down and cooperates with the first air baffle plate 307 to block the exhaust nozzle 306, so that the gas pumped out of the air pump 300 passes through the diverter baffle 310 and is discharged through the cleaning air nozzle 309, blowing to the top of the filter screen 302, so that the lees attached to the bottom of the filter screen 302 are forced to move down and back to the inside of the arc cavity 213.
