[0016] Compared with the prior art, the present invention provides a soybean powder processing raw material screening device, which has the following

[0017] Beneficial effects:

[0018] 1. Through the screening components set up, the purpose of multi-level screening of soybean powder raw materials and automatic screening of soybean powder of different qualities is achieved. At the same time, it is convenient to flexibly adjust the number of screenings according to the particle size of the raw materials and reduce the screening time of raw materials with smaller volumes.

[0019] 2. Through the setting of the push-up assembly, the bean powder raw material repeatedly completes the process of rolling screening along the screen and being pushed to the highest point of the inclined plate by the push-up assembly, thereby realizing the repeated screening process of the bean powder raw material, reducing the possibility that a small volume of bean powder is blocked by a large volume of bean powder raw material and fails to pass through the screen to complete the screening, and ensuring that all small volumes of bean powder can complete the screening.

[0020] 3. Through the material guiding assembly, when the bean powder raw material is less, the bean powder raw material stacked on one side of the screen can be directly dispersed to the middle of the screen. When the bean powder is more, the bean powder raw material can be gradually dispersed to the middle of the screen through multiple elastic arc plates. The method of dispersing the bean powder can be flexibly adjusted according to the specific amount of the screened bean powder raw material, so that the bean powder stacked on one side of the screen during feeding can be more evenly distributed on the screen, thereby reducing the impact of the stacking of bean powder raw materials on the screening of bean powder.

[0021] 4. By setting up the pushing assembly, the arc block can be kept vertical to the inclined plate when the arc block pushes the bean powder raw material to rise, so as to better push the bean powder raw material to rise. When the arc block descends, it can rotate so that the arc block can move over the bean powder raw material to the bottom of the circulation groove. When the bean powder is stuck at the bottom of the arc block, the brush head can be squeezed and bent, thereby preventing the arc block from being stuck by the bean powder raw material and unable to move along the circulation groove. It can also ensure that the brush head is always in contact with the circulation groove, pushing the bean powder raw material in the circulation groove to move to the highest point along the inclined plate.

[0022] 5. The longitudinal rod is set to limit the height of the bean powder raw material in the middle of the screen, preventing the bean powder raw material from piling up in the middle of the screen and affecting the screening effect.

[0023] 6. The scraper plate, long rod and counterweight ball are set to facilitate the removal of the bean powder on the screen. At the same time, the squeezing force between the scraper plate and the screen can be ensured to prevent the scraper plate from detaching from the screen, resulting in part of the bean powder not being scraped away.

DETAILED DESCRIPTION

[0036] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0037] Embodiment 1

[0038] The main purpose of soybean meal screening is to separate the raw materials into two parts: large particles under the screen and small particles over the screen. The difference between the under the screen and the over the screen is as follows:

[0039] Screening material: The screening material of soybean meal refers to the large particles screened out after the beans or bean cakes are ground and processed, including bean skins, large particles of bean dregs, unbroken beans, etc. The screening material contains more nutrients such as protein, fat and carbohydrates, but due to the large particles, it is not suitable for direct use in food production.

[0040] Oversize: The oversize of soybean meal refers to small particles separated through the screening process, including small particles of dregs, soy powder, bean paste, etc. The soy powder in the oversize contains higher protein and fat, and is one of the important raw materials for soy powder processing. The dregs in the oversize contain more nutrients such as cellulose, protein, phosphate, etc., and can be directly used in the production of vegetarian foods such as tofu and bean skin.

[0041] In order to achieve multi-level screening of soybean powder raw materials, the number of screenings can be flexibly adjusted according to the different conditions of the soybean powder raw materials. Figure 1-Figure 6 As one embodiment of the present invention, a soybean powder processing raw material screening device comprises a bottom plate 1 with supporting legs, a screening box 2 is fixedly connected to the top of the bottom plate 1, side brackets 3 are fixedly connected to both sides of the inner wall of the screening box 2, a screening component 4 is installed between the two side brackets 3, and the bean paste in the soybean meal is screened out by at least one screening component 4, and a vibration component 5 is installed on the top of the bottom plate 1 to drive the side bracket 3 and the screening component 4 to vibrate. When in use, the soybean meal is placed on the screening component 4 at the highest point inside the screening box 2, and a plurality of screening components 4 are installed at intervals in the screening box 2 according to the number of required classifications, and the screening aperture of the screening component 4 gradually decreases from top to bottom, and the screening component 4 slides downward from the top of the screening box 2 along the two side brackets 3 into the screening box 2, and then is fixed by bolts, and the vibration component 5 drives the screening component 4 to vibrate for screening, and the soybean meal falls downward after passing through the screening component 4 once, completing a screening until it falls to the bottom of the screening box 2, so as to facilitate and flexibly adjust the number of screening components 4 to meet the needs of different sorting quantities.

[0042] When it is necessary to screen the bean powder with larger particles, the staff can determine the screening component 4 where the largest particle in the bean powder is located, and then put the bean powder directly on the screening component 4 of the appropriate layer height, and then start screening the bean powder from the screening component 4 on the layer where it is placed, until the screening process is completed after passing through the screening component 4 at the bottom. When taking the material at last, the staff transfers the bean powder that has been screened with different apertures under each layer of the screening component 4 to different containers, thereby achieving the purpose of multi-stage screening of the bean powder raw material and automatically screening out bean powder of different qualities. At the same time, it is convenient to flexibly adjust the number of screenings according to the particle size of the raw material, and reduce the screening time of raw materials with smaller volume.

[0043] In order to achieve multiple screening of raw materials in a single screening component 4, to ensure that the bean powder with a smaller volume can pass through the screening component 4 smoothly to complete the screening purpose, refer to Figure 3 and Figure 4 The screening assembly 4 includes an inclined plate 41 installed between two side brackets 3. Both ends of the inclined plate 41 are provided with a limit plate 42 slidably connected to the side bracket 3. One side of the limit plate 42 is fixedly connected to the side bracket 3 by bolts. The top of the inclined plate 41 is provided with a screen 43 that penetrates the inclined plate 41. The top of the inclined plate 41 is provided with a circulation groove on the outer circle of the screen 43. The middle area of ​​the inner bottom of the circulation groove is an upwardly convex arc surface. The side of the circulation groove close to the top of the screen 43 is a downwardly concave arc surface and chamfered. The top of the inclined plate 41 is installed with an upward push assembly 44 for pushing the raw material at the bottom of the circulation groove to move to the top of the circulation groove. The top of the screen 43 is installed There are multiple material guiding components 45, which reduce the angle of guiding the bean powder to deviate to the middle of the screen 43 when there is more bean powder on the surface, and increase the angle of guiding the bean powder to deviate to the middle of the screen 43 when there is less bean powder on the surface. When in use, the vibration component 5 drives the side bracket 3, the inclined plate 41 and the screen 43 to vibrate, and drives the bean powder raw materials on the screen 43 to vibrate and roll downward along the screen 43. The bean powder with a smaller volume passes through the screen 43 and falls downward, completing a screening of the bean powder, while the bean powder raw materials with a larger volume stay on the screen 43, and finally roll to the bottom of the circulation groove along the screen 43, and then roll to both sides along the arc surface of the inner bottom of the circulation groove.

[0044] The pushing assembly 44 pushes the bean powder raw materials on both sides of the bottom of the circulation groove upward along the circulation groove until they are pushed to the highest point of the circulation groove. Then, under the action of the vibration of the inclined plate 41, the bean powder raw materials at the highest point of the inclined plate 41 roll along the arc surface of the circulation groove close to the top of the screen 43 onto the screen 43, and then roll down along the inclined screen 43 again to complete a screening. The bean powder raw materials repeat the process of rolling screening along the screen 43 and being pushed to the highest point of the inclined plate 41 by the pushing assembly 44, thereby realizing the repeated screening process of the bean powder raw materials, reducing the possibility that small-volume bean powder is blocked by large-volume bean powder raw materials and fails to pass through the screen 43 to complete the screening, and ensuring that all small-volume bean powder can complete the screening.

[0045] The screen 43 can be divided into edge areas on both sides and an intermediate area near the middle along its width direction, including the middle of the screen 43 and a small area near the middle. When the bean powder raw material is put onto the screening component 4, due to uneven feeding, even if the bean powder is partially blocked by the protective plate above the middle of the screen 43, it will still fall into the small area near the middle of the intermediate area, which makes it easy for the bean powder raw material to be stacked in the middle area of ​​the screen 43 or on one side of the screen 43. The uneven distribution of the bean powder raw material on the screen 43 will easily affect the effect of bean powder screening. For the situation where the bean powder raw material is stacked in the middle of the screen 43, the stacked bean powder raw material can be transferred to other areas by the push-up component 44. The specific process is described in the working process of the push-up component 44. For the situation where the bean powder raw material is stacked on one side of the screen 43, refer to Figure 5 and Figure 6 The material guide assembly 45 includes a plurality of vertical rods 451 distributed on the edges of both sides of the screen 43, one side of the vertical rods 451 is fixedly connected with an elastic arc plate 452, and one side of the elastic arc plate 452 is fixedly connected with a transverse thin plate 453 with an inclined top end. When in use, the bean powder material stacked on one side of the screen 43 rolls down along the inclined screen 43 under the vibration of the screen 43, and the bean powder material rolling down more squeezes the elastic arc plate 452. According to the different weights of the bean powder material squeezing the elastic arc plate 452, there are two cases, which are as follows:

[0046] When the amount of bean powder raw material squeezing the elastic arc plate 452 is small, the elastic arc plate 452 is squeezed with a small force, so the bending degree of the elastic arc plate 452 is small, and the bean powder raw material will move a long distance toward the middle of the screen 43 along the inclined elastic arc plate 452, so that the bean powder raw material is moved to a position close to the middle of the screen 43; when the amount of bean powder raw material squeezing the elastic arc plate 452 is large, the elastic arc plate 452 at the highest point is squeezed with a large force, resulting in a large degree of bending, and the bean powder raw material moves a short distance toward the middle of the screen 43 along the elastic arc plate 452 squeezed and bent at the highest point, and part of the bean powder raw material will still return to one side of the screen 43, so the bean powder raw material still stays at a position close to one side of the screen 43, and the bean powder raw material is pushed away by the elastic arc plate 452 at the highest point. After the bean powder raw material is squeezed by the next elastic arc plate 452, the weight of the bean powder raw material squeezed by the next elastic arc plate 452 is reduced, so the force of squeezing the subsequent elastic arc plate 452 will gradually decrease, and the subsequent elastic arc plate 452 will guide the bean powder raw material to move a farther distance closer to the middle of the screen 43, so that the bean powder raw material stacked on one side of the screen 43 is gradually dispersed. When the bean powder raw material is less, the bean powder raw material stacked on one side of the screen 43 can be directly dispersed to the middle of the screen 43, and when the bean powder is more, the bean powder raw material can be gradually dispersed to the middle of the screen 43 through multiple elastic arc plates 452. The method of dispersing the bean powder can be flexibly adjusted according to the specific amount of the bean powder raw material to be screened, so that the bean powder stacked on one side of the screen 43 when feeding is more evenly distributed on the screen 43, thereby reducing the influence of the stacking of bean powder raw materials on the screening of bean powder.

[0047] When the bean powder squeezed by the elastic arc plate 452 passes over the elastic arc plate 452, the elastic arc plate 452 will move toward the starting point due to its own elasticity, driving the transverse thin plate 453 to collide with the bean powder raw material, which can not only push the stacked bean powder raw material to move a longer distance to the middle of the screen 43, but also use the impact to crush the bean powder raw material, thereby improving the screening rate of small-volume bean powder.

[0048] In order to facilitate the observation of the screening process of the bean powder raw materials and to facilitate the flexible placement of the bean powder raw materials on the screening components 4 of different layers according to the specific particle size of the bean powder raw materials, refer to Figure 1 and Figure 2 The screening box 2 includes an outer frame 21 with an opening on one side, and a cover plate 22 for covering the opening is slidably connected to one side of the outer frame 21. The screening box 2 adopts a split structure, and the cover plate 22 on one side can be opened, which is convenient for placing the soybean powder raw materials on the screening components 4 with different numbers of layers from one side of the screening box 2, and also convenient for the staff to observe the specific situation of the screening from the side of the screening component 4.

[0049] In order to facilitate the removal of the sorted soybean powder, refer to Figure 1A plurality of square holes matching the notches of the side bracket 3 are provided on one side of the screening box 2, a bin door 14 for covering the square holes is rotatably connected to one side of the screening box 2, and a handle 15 is fixedly connected to the side of the bin door 14 away from the screening box 2. After the screening is completed, bean powder of different particle sizes stays on the screens 43 of different layers, the vibration component 5 is started continuously, and then the bin door 14 is opened, and the bean powder on the screen 43 continues to roll down along the inclined screen 43 until it rolls to the lowest point of the inclined plate 41 and is discharged from the square holes at different heights. By using a container to catch the bean powder discharged from the square holes at different heights, the bean powder can be sorted into different particle size grades.

[0050] Embodiment 2

[0051] In order to realize the cyclic screening of bean powder raw materials on a screen 43, it is ensured that all bean powders with smaller volumes can be screened out. Figure 1-Figure 8 On the basis of the first embodiment, the push-up assembly 44 includes side plates 441 installed at both ends of the top of the inclined plate 41, one side of one side plate 441 is fixedly connected to a motor 442, a threaded rod 443 is provided between the output end of the motor 442 and the other side plate 441, the outer sleeve of the threaded rod 443 is provided with a cross block 444, the bottom of the cross block 444 is provided with a push assembly 445 with one end movably extending to the inside of the circulation groove, and a protective plate for covering the threaded rod 443 is fixedly connected between the tops of the two side plates 441. When in use, the bean powder raw materials on the inclined plate 41 roll along the inclined plate 41 to the bottom of the circulation groove under the vibration of the inclined plate 41, and then roll to both sides along the arc surface of the bottom of the circulation groove, and the motor The motor 442 drives the threaded rod 443 to rotate, thereby driving the cross block 444 to move along the length direction of the inclined plate 41, driving the pushing assembly 445 to push the bean powder raw material at the bottom of the circulation groove to the highest point of the circulation groove, and then the bean powder raw material is vibrated by the inclined plate 41 to the screen 43 for screening. Then the motor 442 rotates in the opposite direction, driving the cross block 444 and the pushing assembly 445 to move to the starting point, and repeating the above process, continuously pushing the bean powder raw material at the bottom of the inclined plate 41 to move to the highest point of the inclined plate 41, and then moving it back to the bottom of the inclined plate 41 under the action of vibration, and screening the bean powder raw material for multiple cycles to prevent the smaller bean powder from being blocked by the larger bean powder raw material and not being screened out.

[0052] The specific process of the bean powder being pushed to the highest point by the push-up assembly 42 and then vibrated again by the inclined plate 41 onto the screen 43 for screening is as follows: First, the push assembly 445 is an inclined plate, and when it moves along the circulation groove to push the bean powder, the bean powder will not slide to one side out of the circulation groove due to the limit on both sides of the circulation groove. When the push assembly 445 rises to the highest point of the circulation groove along the circulation groove, due to the shape of the circulation groove, the width of the highest point of the circulation groove increases, and one side of the push assembly 445 is no longer blocked by the side wall of the circulation groove. At this time, the push assembly 445 The bean powder on the surface will slide to one side along the inclined pushing assembly 445, that is, slide toward the middle direction of the screen 43. At the same time, it should be noted that this process and the subsequent process of the bean powder at the highest point of the circulation groove moving to the screen 43 are all carried out when the screen 43 is always vibrating. The vibrating screen 43 will drive the bean powder thereon to move from a relatively high place to a relatively low place, and the entire inclined plate 41 and the screen 43 are inclined. Under the action of vibration, the bean powder inside the circulation groove at a high place will move to the screen 43 at a lower place of the inclined plate 41.

[0053] Both sides of the cross block 444 are fixedly connected with a telescopic hose for wrapping the threaded rod 443 to prevent bean powder from falling on the surface of the threaded rod 443, maintain a clean environment on the surface of the threaded rod 443, and avoid particles in the bean powder screening process from being stuck in the gap between the threaded rod and the cross block, thereby ensuring the smooth operation of the push-up assembly.

[0054] In order to enable the pusher assembly 445 to move to the bottom without being blocked by the bean powder material inside the circulation groove, and also to prevent the bean powder material from getting stuck at the bottom of the pusher assembly 445 so that the pusher assembly 445 cannot move along the circulation groove, refer to Figure 8 The pushing assembly 445 includes an arc block 4451 installed at the bottom of the horizontal block 444, and a limiting groove corresponding to the arc block 4451 is opened on one side of the horizontal block 444. A limiting block 4452 is provided on the top of the arc block 4451, and one end of the limiting block 4452 is movably extended to the inside of the limiting groove. The limiting block 4452 is rotatably connected to the inner wall of the limiting groove, and a brush head 4453 is fixedly connected to the bottom of the arc block 4451. When in use, when the horizontal block 444 drives the pushing assembly 445 to move upward along the inclined plate 41, the arc block 4451 is subjected to the reaction force of the soybean powder raw material that is pushed up, pushing the limiting block 4452 to be squeezed on one side of the limiting groove. At this time, the limiting block 4452 and the arc block 4451 are perpendicular to the surface of the inclined plate 41, pushing the soybean powder raw material inside the circulation groove to rise.

[0055] When the horizontal block 444 drives the pushing assembly 445 to move downward along the inclined plate 41, the arc block 4451 is blocked by the bean powder material inside the circulation groove, and the arc block 4451 and the limit block 4452 are driven to rotate relative to the horizontal block 444 under the reaction force of the bean powder, so that the bottom of the arc block 4451 is raised and can pass over the bean powder material, and then continue to move downward along the circulation groove until the arc block 4451 moves to the bottom of the circulation groove. When the arc block 4451 moves upward along the circulation groove again with the horizontal block 444, the arc block 4451 is blocked by the gravity of the bean powder material in the circulation groove and moves again to a direction perpendicular to the inclined plate 41 , pushing the bean powder in the circulation groove to move upward, and being able to keep the arc block 4451 vertical to the inclined plate 41 when the arc block 4451 pushes the bean powder raw material to rise, so as to better push the bean powder raw material to rise, and being able to rotate when the arc block 4451 descends, so that the arc block 4451 can move over the bean powder raw material to the bottom of the circulation groove, and when the bean powder is stuck at the bottom of the arc block 4451, the brush head 4453 can be squeezed and bent, thereby preventing the arc block 4451 from being stuck by the bean powder raw material and unable to move along the circulation groove, and also ensuring that the brush head 4453 is always in contact with the circulation groove, pushing the bean powder raw material in the circulation groove to move to the highest point along the inclined plate 41.

[0056] In order to make the bean powder material stacked in the middle of the screen 43 evenly distributed, refer to Figure 8 A plurality of longitudinal rods 6 that movably penetrate the cross block 444 are provided on the top of the cross block 444, and a cross plate 7 is fixedly connected between the tops of the plurality of longitudinal rods 6. When the bean powder raw materials are concentrated in the middle of the screen 43 during feeding, the staff can press the cross plate 7 downward to push the longitudinal rods 6 down to a suitable height, and then the cross block 444 moves along the length direction of the inclined plate 41 driven by the threaded rods 443. During this process, the bean powder raw materials that are higher than the bottom of the longitudinal rods 6 are pushed to both sides by the longitudinal rods 6, while the bean powder raw materials that are lower than the bottom of the longitudinal rods 6 pass under the longitudinal rods 6, which can limit the height of the bean powder raw materials in the middle of the screen 43 and prevent the bean powder raw materials from stacking in the middle of the screen 43 and affecting the screening effect.

[0057] Embodiment 3

[0058] In order to conveniently remove the bean powder on the surface of the screen 43, refer to Figure 1-Figure 9On the basis of the first embodiment, a scraper plate 8 is provided inside the screening box 2, and a rotating block 9 is rotatably connected to one side of the scraper plate 8, and a bracket 10 is fixedly connected to the side of the rotating block 9 away from the scraper plate 8. A long rod 11 with one end movably extending to the outside thereof is provided inside the bracket 10, and a plurality of rubber straps for fixing the long rod 11 and the scraper plate 8 are fixedly connected to the top of the bottom plate 1 to prevent the scraper plate 8 and the long rod 11 from moving and hitting the edge of the device when the vibration motor 53 drives the screen 43 to vibrate. Two limiting round blocks 12 are fixedly connected to the outside of the long rod 11, and a counterweight ball 13 is provided between the two limiting round blocks 12 and is sleeved on the outside of the long rod 11. The counterweight ball 13 is slidably connected to the long rod 11. When in use, the staff holds the long rod 11 to take out the scraper plate 8 from the bottom of the screening box 2, and then moves to the screen 43 where the bean powder needs to be cleaned. In order to increase the squeezing force between the scraper plate 8 and the screen 43 and prevent the scraper plate 8 from detaching from the screen 43, resulting in some bean powder not being scraped away, the staff can lift the end of the long rod 11 away from the scraper plate 8, so that the counterweight ball 13 slides along the long rod 11 to the end close to the scraper plate 8. The counterweight ball 13 drives the scraper plate 8 to press the screen 43 downward under the action of its own gravity, thereby ensuring the squeezing force between the scraper plate 8 and the screen 43. Then the staff pulls the long rod 11 to drive the scraper plate 8 to move from one side of the screen 43 to the other side of the screen 43, and scrapes away the bean powder on the screen 43. Finally, a container is used to hold the bean powder scraped off the screen 43, which is convenient for removing the bean powder on the screen 43 and at the same time can ensure the squeezing force between the scraper plate 8 and the screen 43, thereby preventing the scraper plate 8 from detaching from the screen 43, resulting in some bean powder not being scraped away.

[0059] Compared with directly fixing the counterweight ball 13 on the end of the long rod 11 close to the scraper plate 8, the present embodiment adopts a slidable counterweight ball 13. When not scraping, the staff can move the end of the long rod 11 away from the scraper plate 8 downward, so that the height of the end of the long rod 11 that is used to scrape the raw material is lower than the height of the scraper plate 8, so that the counterweight ball 13 slides to the end of the long rod 11 away from the scraper plate 8. Therefore, when the staff moves the scraper plate 8, since the distance between the counterweight ball 13 and the staff holding the long rod 11 is shorter and the torque is smaller, the force required for the staff to move the long rod 11 can be reduced, making the movement of the scraper plate 8 more convenient.

[0061] In order to drive the inclined plate 41 and the screen 43 to vibrate, so that the bean powder raw material is screened on the vibrating screen 43, refer to Figure 1-Figure 10On the basis of the first embodiment, the vibration component 5 includes a limit frame 51 fixedly connected to the base plate 1, a support platform 52 with an inclined top is installed inside the limit frame 51, and a vibration motor 53 is fixedly connected to the top of the support platform 52. When in use, the support platform 52 is fixed in the limit frame 51, and a support platform 52 with a suitable top inclination angle can be selected according to needs, and the vibration motor 53 is fixed to the top of the support platform 52. The inclination angle of the vibration motor 53 is the same as the inclination angle of the top of the support platform 52, and the inclination angle of the vibration motor 53 can be flexibly selected according to the vibration amplitude.
