Description

Technical Field

[0001] This invention relates to the field of material conveying, and more particularly to a granular material grading and conveying device. Background Technology

[0002] Baijiu is a traditional fermentation industry in China with a long history and unique flavor. It carries the traditional Chinese brewing culture and profound historical connotations. After the base liquor production capacity is expanded, the demand for raw and auxiliary materials increases and the transportation distance becomes longer. In addition, a large amount of brewing raw materials are entering the factory area and transporting raw and auxiliary materials from the original production workshops. This results in a longer transportation cycle for raw and auxiliary materials in the expansion project, an increased number of transport vehicles, and a doubling of energy consumption. This can easily cause congestion at the raw and auxiliary material distribution point and on the factory area, affecting the normal production order of the distillery.

[0003] Therefore, reducing energy consumption and shortening material transportation cycles are of paramount importance for the transformation and upgrading of the liquor industry towards intelligent production. Our research on positive pressure dense phase conveying systems revealed that these devices are simple, occupy little space, and have high conveying efficiency. They achieve maximum production value with minimal manual input, significantly reducing labor costs. The positive pressure dense phase conveying process is dust-free throughout, greatly improving the workshop production environment. However, it is necessary to consider issues such as excessive resistance during long-distance material transportation, pipe blockages during positive pressure conveying, difficulties in cleaning, and severe stratification and classification phenomena when unloading from the temporary storage bin at the end of the pneumatic conveying process due to varying particle sizes. The materials mainly include sorghum, yeast powder, and rice husks. Summary of the Invention

[0004] To overcome the difficulties in cleaning and the severe stratification and classification caused by uneven particle size, which makes it impossible to use a positive pressure dense phase conveying system, this invention provides a particulate material classification and conveying device.

[0005] A granular material grading and conveying device includes a compressed air source tank, a support frame, pipes, air valves, a conveying pipe, a discharge hopper, a discharge valve, a separating mechanism, and a vibration component. The compressed air source tank is located on the left side of the support frame, and the discharge hopper is located on the upper right side of the support frame. A separating mechanism for separating three raw materials according to their diameter is located on the lower right side of the support frame and is located at the bottom of the discharge hopper. A discharge valve is rotatably connected to the lower end of the discharge hopper. Pipes are connected to both the compressed air source tank, the discharge hopper, and the separating mechanism, and air valves are installed on each pipe. A conveying pipe is connected to the bottom of the separating mechanism, and the conveying pipes are connected to each other through flanges to extend the conveying distance. A vibration component for vibrating the material is installed inside the separating mechanism.

[0006] Furthermore, it is particularly preferred that the material dispensing mechanism includes a dispensing box, a primary filter, a secondary filter, a three-way push plate, and a servo motor. The dispensing box is fixedly connected to the support frame, with its top fixedly connected to the discharge hopper and its bottom connected to the conveying pipe. The primary and secondary filters are fixedly connected inside the dispensing box, and both the primary and secondary filters occupy one-third of the cross-sectional area inside the dispensing box. The gap of the primary filter is smaller than that of the secondary filter. The primary filter is located directly below the discharge hopper. The three-way push plate is rotatably connected inside the dispensing box. The servo motor is fixedly connected to the top of the dispensing box, with its output shaft facing downward and fixedly connected to the top of the three-way push plate.

[0007] Furthermore, it is particularly preferred that the vibration assembly includes a wave ring, a pull rod, a sliding rod, a vibrating plate, and an elastic element. The wave ring is fixed inside the material distribution box. The top of the three-way push plate has a groove for the wave ring to pass through. A pull rod is fixed to the right end of each plate of the three-way push plate. A through hole is opened at the other end of the pull rod, and a sliding rod is slidably connected in the through hole. The top of the sliding rod is slidably connected to the top surface of the wave ring. A vibrating plate is fixed to the bottom of the sliding rod, and an elastic element is sleeved at the lower end of the sliding rod, located between the pull rod and the vibrating plate.

[0008] Furthermore, it is particularly preferred that the plate also includes a cross plate and a connecting plate, with the inner end of the connecting plate fixedly connected to the center connection of the three-way push plate, and the cross plate rotatably connected to the outer end of the connecting plate, and the lower end of the cross plate having multiple through slots.

[0009] Furthermore, it is particularly preferred that the device also includes a central wheel and planetary wheels, with the central wheel fixedly connected to the bottom of the top plate of the distribution box, and planetary wheels fixedly connected to the top of the cross plate, and the central wheel meshing with all the planetary wheels.

[0010] In addition, it is particularly preferred that a cleaning brush is included, which is fixed to the bottom of the three-way push plate and is located on the same side of the three-way push plate as the pull rod.

[0011] In addition, it is particularly preferred that the box also includes a cover plate, which is rotatably connected to the bottom of the top plate of the dispensing box, and the dispensing box has a corresponding observation window.

[0012] Furthermore, it is particularly preferred that an observation plate is included, which is provided on the conveying pipe.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. This invention uses a material distribution box divided into three areas and a three-way pusher plate to move the material through a primary filter and a secondary filter in sequence to complete the material distribution.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0027] Example: A particulate material grading and conveying device, such as Figures 1-4 As shown, a positive pressure dense phase conveying system is used, including a compressed air source system, a feeding system, a distributing system, a pipeline system, and auxiliary systems. The compressed air source system compresses air to provide transportation power and mainly includes a compressed air source tank 1, a pipeline 12, and an air valve 13. The feeding system is used to store the materials to be transported and mainly includes a support frame 11, a discharge tank 2, and a discharge valve 21. The distributing system is used to distribute the three raw materials according to their diameter and mainly includes a distributing mechanism and a vibration component. The pipeline system provides the transportation environment and mainly consists of a conveying pipe 14. The auxiliary system includes the support frame 11 and an equipment controller, etc. The support frame 11 is welded to the left side. A compressed air source tank 1 is connected to the support frame 11. A feeding tank 2 is welded to the upper right side of the support frame 11. A material distribution mechanism for distributing three raw materials according to their diameter is welded to the lower right side of the support frame 11. The feeding tank 2 is located at the bottom of the feeding tank 2. A feeding valve 21 is rotatably connected to the lower end of the feeding tank 2. The compressed air source tank 1, the feeding tank 2, and the material distribution mechanism are all connected by pipes 12. Air valves 13 are rotatably connected to each pipe 12. A conveying pipe 14 is connected to the bottom of the material distribution mechanism. The conveying pipes 14 are connected to each other by flanges to extend the transportation distance. An observation plate 141 is fixed to the conveying pipe 14. A vibration component for vibrating the material is installed inside the material distribution mechanism.

[0028] like Figures 3-5 As shown, the material distribution mechanism includes a material distribution box 3, a primary filter screen 31, a secondary filter screen 32, a three-way push plate 33, and a servo motor 34. The material distribution box 3 is welded to the support frame 11, and its top is welded to the discharge bucket 2. The three through holes at the bottom are connected to the conveying pipe 14 through flanges. The discharge bucket 2 is welded inside the material distribution box 3, and the primary filter screen 31 and the secondary filter screen 32 are welded thereon. The primary filter screen 31 and the secondary filter screen 32 each occupy one-third of the cross-sectional area inside the material distribution box 3, and the gap of the primary filter screen 31 is smaller than that of the secondary filter screen 32. The primary filter screen 31 is located directly below the discharge bucket 2. The three-way push plate 33 is rotatably connected inside the material distribution box 3. The servo motor 34 is welded to the top of the material distribution box 3, with its output shaft facing downwards and welded to the top of the three-way push plate 33.

[0029] like Figure 4 and Figure 5 As shown, the vibration assembly includes a wave ring 4, a pull rod 41, a sliding rod 42, a vibrating plate 43, and an elastic element 44. The wave ring 4 is welded inside the distribution box 3. The surface height of the wave ring 4 is inconsistent, and arc-shaped protrusions are provided at intervals. The top of the three-way push plate 33 has a groove for the wave ring 4 to pass through. A pull rod 41 is welded to the right end of each plate of the three-way push plate 33. A through hole is opened at the other end of the pull rod 41, and a sliding rod 42 is slidably connected in the through hole. The top of the sliding rod 42 is slidably connected to the top surface of the wave ring 4. A vibrating plate 43 is welded to the bottom of the sliding rod 42, and an elastic element 44 is sleeved at the lower end of the sliding rod 42, located between the pull rod 41 and the vibrating plate 43.

[0030] Workers pour the mixed materials into the feeding hopper 2 and turn on the compressed air supply system. Compressed air is stored in the compressed air supply hopper 1. Simultaneously, the air valve 13, feeding valve 21, and servo motor 34 are opened. The compressed gas, after passing through pipe 12, pushes the materials down. The servo motor 34 drives the three-way pusher plate 33 to rotate, and the materials fall onto the primary filter screen 31. The gap of the primary filter screen 31 is smaller than the diameter of the rice husks and sorghum, allowing only the koji powder to pass through, thus completing the separation of koji powder. Subsequently, the three-way pusher plate 33 pushes the sorghum and rice husks to continue moving. When they contact the secondary filter screen 32, because the gap of the secondary filter screen 32 is smaller than the sorghum, the rice husks are separated. The remaining sorghum is pushed into the filterless area and falls directly down, thus completing the separation of the three raw materials. The three raw materials then enter their respective conveying pipes 14. The material ratio is sorghum:rice husk:koji powder = 1:0.68: 0.28, and the air volume of different conveying pipes 14 is different. After setting according to the research report, the three raw materials are transported to the destination along the conveying pipe 14. During the transportation, the situation inside the conveying pipe 14 can be observed through the observation plate 141. When distributing materials, the rotating three-way push plate 33 drives the pull rod 41 to rotate, thereby driving the sliding rod 42 to slide around the wave ring 4. Due to the inconsistent height of the surface of the wave ring 4, the sliding rod 42 moves up and down. During the movement, it is reset by the elastic element 44. The vibrating plate 43 follows the sliding rod 42 up and down and knocks on the primary filter screen 31 and the secondary filter screen 32, which can vibrate the material on the primary filter screen 31 and the secondary filter screen 32, which helps the material fall and change position, and optimizes the situation where the material cannot be distributed due to the large diameter material blocking the gap. After the material distribution is completed, the air valve 13, the discharge valve 21 and the servo motor 34 are closed.

[0031] like Figure 4 and Figure 6 As shown, it also includes a cross plate 5 and a connecting plate 51. The inner end of the connecting plate 51 is welded to the center connection of the three-way push plate 33. The cross plate 5 is rotatably connected to the outer end of the connecting plate 51, and multiple through slots are opened downward at the lower end of the cross plate 5.

[0032] like Figure 4 and Figure 7 As shown, it also includes a central wheel 6 and planetary wheels 61. The central wheel 6 is welded to the bottom of the top plate of the distribution box 3, and planetary wheels 61 are welded to the top of the cross plate 5. The central wheel 6 and all planetary wheels 61 mesh with each other.

[0033] like Figure 7 and Figure 8 As shown, it also includes a cleaning brush 7, which is welded to the bottom of the three-way push plate 33 and is located on the same side of the three-way push plate 33 as the pull rod 41.

[0034] like Figure 1 and Figure 4As shown, it also includes a cover plate 8, which is rotatably connected to the bottom of the top plate of the material distribution box 3, and the material distribution box 3 has a corresponding observation window.

[0035] When the three-way push plate 33 rotates, it also drives the connecting plate 51 to rotate, which in turn causes the cross plate 5 to rotate inside the distribution box 3. The lower end of the cross plate 5 has multiple through slots that form a large brush, which agitates the material on the primary filter screen 31 and the secondary filter screen 32. After being connected to the planetary gear 61, the planetary gear 61 meshes with the fixed center wheel 6 and rotates. Thus, while the cross plate 5 rotates around the center of the distribution box 3, it also rotates on its own axis, optimizing the agitation of the material and thus optimizing the distribution effect. In addition, a cleaning brush 7 is connected to the bottom of the three-way push plate 33 to clean the primary filter screen 31 and the secondary filter screen 32. In particular, the powder distributed by the primary filter screen 31 can be observed through the cover plate 8, and any problems can be dealt with directly, which is convenient for subsequent maintenance.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
