Description

Technical Field

[0001] This invention relates to the field of material conveying technology in wineries, specifically to a uniform material conveying device and method for wineries. Background Technology

[0002] In traditional brewing processes such as baijiu and huangjiu, grain raw materials must be crushed and evenly fed into the storage chamber to ensure the stability and consistency of subsequent cooking, saccharification, and fermentation processes. If particle size segregation or component separation occurs during material transportation, it will lead to uneven permeability of the material layer and an imbalance in heat and mass transfer, thus affecting the yield and flavor of the liquor. Therefore, existing processes generally employ anti-segregation devices to homogenize the materials entering the storage chamber.

[0003] However, the existing conveying devices still have the following problems in the process of feeding materials to the anti-grading device: The existing feeding process is highly dependent on the stability of the front-end conveyor. Once the conveying flow fluctuates or is unevenly distributed, the material is prone to concentrated feeding and local accumulation due to drop impact or airflow disturbance before entering the anti-grading device. This results in intermittent feeding, turbulent flow, and even component segregation, making it difficult to meet the basic requirements of the anti-grading device for continuous and uniform feeding, thus preventing its anti-grading function from being effectively performed.

[0004] The crushed material itself has significant differences in density and particle size between the core and the shell. Under the combined action of airflow, gravity and vibration, the light shell is easy to float and the heavy core is easy to sink. Natural segregation occurs before entering the anti-segregation device. Existing conveying devices mostly adopt static material dropping structure, which can not suppress material scattering and lacks active control over the falling trajectory and dispersion state. This causes the upper and lower layers of material to interfere with each other, and the spatial distribution of material is uneven, which further aggravates component separation and weakens the overall anti-segregation effect. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a uniform material conveying device and method for wineries, solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a uniform material conveying device for a winery, comprising: an anti-grading device; a buffer pipe installed at the upper end of the feed inlet of the anti-grading device; a distribution hopper, which is uniformly spaced along the axial direction of the buffer pipe, with a discharge port at the bottom of each distribution hopper, wherein the discharge ports of adjacent distribution hoppers are radially offset and can rotate synchronously in opposite directions at different speeds, so that the material enters the anti-grading device continuously and uniformly in a planar form through the dynamically offset discharge ports; and a baffle plate, which is provided above each distribution hopper to suppress the upward dispersion of material under airflow disturbance.

[0007] Furthermore, the discharge port is an arc-shaped groove extending circumferentially along the distribution hopper. From top to bottom, the arc-shaped grooves of each distribution hopper are offset radially from the outer circumference to the inner circumference, and the bottom surface of the distribution hopper is inclined toward the corresponding arc-shaped groove.

[0008] Furthermore, the discharge port consists of multiple circular through holes evenly distributed around the bottom of the distribution hopper. From top to bottom, the circular through holes of each distribution hopper are offset radially from the outer periphery to the inner periphery, and the inner bottom surface of the distribution hopper is inclined toward its corresponding circular through hole.

[0009] Furthermore, the baffle plate is provided in multiple ways and is evenly distributed along the radial direction of the corresponding material distribution hopper. Each baffle plate is inclined and a gradually narrowing flow guide gap is formed between adjacent baffle plates. The whole structure constitutes a louvered baffle structure. Multiple baffle plates are hinged together on the inner ring surface of the same fixed ring, and the fixed ring is fixedly sleeved in the buffer pipe.

[0010] Furthermore, the baffles above the different material hoppers have a phase difference in the circumferential direction and their tilt angles are different, which are used to control the airflow disturbance and dispersion trend during the falling process of each layer of material.

[0011] Furthermore, each of the baffle plates located on the same horizontal plane has a connecting shaft installed at the middle of its upper end. An adjusting ring is rotatably sleeved on the outer circumference of the connecting shaft. Adjacent adjusting rings are connected by a connecting rod. An adjusting screw is rotatably installed on the outer side of one of the adjusting rings. The adjusting screw is threaded into the side wall of the buffer pipe and is used to synchronously change the tilt angle of all the baffle plates on the horizontal plane by rotating the adjusting screw.

[0012] Furthermore, the lower end of the baffle plate is equipped with mounting blocks that are evenly distributed along its length, and the lower end of the mounting blocks is connected to a buffer swing rod via a ball joint.

[0013] Furthermore, the outer periphery of the distribution hopper is fixedly fitted with an external toothed ring that is rotatably connected to the buffer pipe. A rotating gear that is rotatably installed on the outer wall of the buffer pipe meshes with the outer toothed ring. The transmission ratio between the external toothed ring and the rotating gear corresponding to adjacent distribution hoppers is different.

[0014] Furthermore, a rotating shaft is provided between the upper and lower adjacent rotating gears. The rotating shaft is fixedly connected to the rotating gear located on the lower side and rotatably connected to the rotating gear located on the upper side. A bushing sleeve is fixedly connected to the lower end of the rotating gear located on the upper side and sleeved on the outside of the rotating shaft. Horizontal bevel gears are fixedly fitted on both the bushing sleeve and the outside of the rotating shaft. A vertical bevel gear meshes between the upper and lower horizontal bevel gears. The rotating shaft located at the bottom is connected to the output shaft of the drive motor.

[0015] This invention also provides a method for uniformly conveying materials in a winery, applicable to a uniform material conveying device in a winery, comprising the following steps: Step 1: The material enters the buffer pipe from the upstream. It first passes through the airflow suppression and preliminary flow stabilization, and then falls into the top-level distribution hopper. The material falls through the discharge port at the bottom of the distribution hopper, passes through the guide gap of the next-level baffle plate, and enters the next layer of distribution hopper. Step 2: Under the action of the upper and lower adjacent distribution hoppers rotating in opposite directions at different speeds, the material is continuously dispersed through the dynamically staggered discharge port during the step-by-step falling process, forming a planar distribution and evenly transitioning to the next level distribution hopper; Step 3: After being regulated by the bottom distribution hopper and the corresponding baffle plate, the material finally enters the anti-grading device in a uniform and continuous planar form, completing the feeding of the anti-grading device.

[0016] The present invention has the following beneficial effects: (1) The uniform material conveying device of the winery, by setting up a buffer pipe before the anti-grading device, allows the material to be decelerated, stabilized and initially distributed before entering the anti-grading device, effectively suppressing the concentrated impact and local accumulation caused by the conveying drop or airflow disturbance, significantly improving the uniformity of feeding, and providing a stable and continuous material flow basis for subsequent anti-grading treatment.

[0017] (2) The uniform material conveying device of the winery sets up a multi-stage material distribution hopper in the buffer pipe. During the process of material falling step by step, it achieves multiple buffering and dispersion through the discharge port. The discharge ports of adjacent material distribution hoppers are complementary and misaligned in the radial direction, and shift from the outer periphery to the inner periphery from top to bottom. With the rotation of the material distribution hopper, the discharge ports of adjacent layers are dynamically combined to form a complete circular discharge trajectory, which promotes the material to fall evenly in a planar form, changing the problem of uneven distribution caused by traditional point or line dropping, and significantly improving the uniformity of material distribution and process stability.

[0018] (3) The uniform material conveying device of the winery allows adjacent hoppers to rotate synchronously in opposite directions at different speeds, so that the relative positional relationship between the upper and lower discharge ports is continuously changing. During the material falling process, dynamic shearing distribution is implemented, which effectively breaks the natural segregation trend of the material caused by differences in particle size or density. The material enters the anti-grading device in a continuous and uniform planar form, which significantly improves the uniformity of feeding.

[0019] (4) The uniform material conveying device of the winery effectively suppresses the floating and scattering of light components under airflow disturbance by setting baffles with an overall louver structure above each distribution hopper, constrains the falling path of materials, avoids local accumulation or excessive dispersion, and ensures that materials enter the next level distribution hopper or anti-grading device smoothly and centrally. In addition, the baffles of different layers have phase differences in the circumferential direction and different inclination angles, so that the guiding direction and constraint strength of each layer on the material are distributed differently, and the material is stably restricted in its corresponding falling channel, effectively preventing material crosstalk between upper and lower layers caused by airflow or inertia, thereby significantly improving the orderliness and overall uniformity of material flow during the multi-level buffer material distribution process.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0025] The following reference Figures 1-13 This invention describes a uniform material conveying device and method for a winery, as provided in an embodiment of the present invention.

[0026] On the one hand, the present invention provides a uniform material conveying device for wineries.

[0027] Example 1, please refer to this example. Figures 1-9 .

[0028] Please refer to Figure 1 The winery's material uniform conveying device includes an anti-grading device 1, which is existing technology. Its core function is to receive the material that falls uniformly from the upstream distribution system and further suppress the separation of the core and shell components caused by differences in particle size and density during the free fall process.

[0029] To improve the uniformity of materials entering the anti-grading device 1, a buffer pipe 2 is installed at the upper end of the feed inlet of the anti-grading device 1. The buffer pipe 2 is fixed to the existing support frame (not shown in the figure) and is connected to it. After the material is fed into the buffer pipe 2 by the upstream conveying device (such as screw conveyor, bucket elevator, etc.), it is first decelerated, stabilized and initially distributed by the buffer pipe 2, which effectively reduces the concentrated impact and local accumulation caused by the conveying drop or airflow disturbance, realizes the pre-homogenization before entering the anti-grading device 1, and provides a stable and continuous material flow basis for subsequent anti-grading treatment.

[0030] Please refer to Figure 2 , Figure 3 and Figure 5 To avoid impact concentration and landing point deviation caused by direct material falling, a distribution hopper 21 is set in the buffer pipe 2, which is evenly distributed along its axial direction. Each distribution hopper 21 has a discharge port at its bottom. After entering the buffer pipe 2, the material falls into the distribution hopper 21 in stages and is transferred to the next stage through the discharge port, realizing multi-stage buffering and material distribution. The discharge ports of the adjacent distribution hoppers 21 are radially complementary and staggered, and the adjacent distribution hoppers 21 can rotate synchronously in opposite directions at different speeds. As a result, a dynamic relative position relationship is formed between the discharge ports, so that the material is continuously sheared and redistributed during the falling process, and finally enters the anti-grading device 1 in a continuous and uniform planar form, which significantly improves the uniformity of feeding and suppresses grading phenomenon.

[0031] Specifically, the discharge port is an arc-shaped groove 211 extending circumferentially along the distribution hopper 21. From top to bottom, the arc-shaped grooves 211 of each distribution hopper 21 are offset radially from the outer periphery to the inner periphery. Adjacent layers of arc-shaped grooves 211 dynamically merge during rotation to form a complete circular discharge trajectory. When the distribution hopper 21 rotates, the arc-shaped grooves 211 sweep to form a continuous annular discharge surface, allowing the material to fall evenly in a planar form. At the same time, the bottom surface of the distribution hopper 21 is inclined towards the corresponding arc-shaped groove 211, using gravity to guide the material to slide smoothly to the discharge port, avoiding material stagnation or accumulation, and ensuring continuous and stable material distribution.

[0032] Additionally, please refer to Figure 2 and Figure 6Each distribution hopper 21 is equipped with a baffle plate 22 above it, and an additional baffle plate 22 is added between the bottom distribution hopper 21 and the feed inlet of the anti-grading device 1 to achieve full-process airflow suppression. Multiple baffle plates 22 are provided and are evenly distributed radially along the distribution hopper 21. Each baffle plate 22 is inclined and a gradually narrowing guide gap is formed between adjacent baffle plates 22, forming a louvered baffle structure. Multiple baffle plates 22 are hinged together on the inner ring surface of the same fixed ring 221. The fixed ring 221 is fixedly sleeved in the buffer pipe 2. When the material falls, it first passes through the guide channel formed by the baffle plate 22. The louver structure effectively blocks the floating and scattering of light components under airflow disturbance, constrains the falling path of the material, prevents local accumulation or dispersion, and ensures that it enters the next level distribution hopper 21 or the anti-grading device 1 smoothly and centrally.

[0033] To improve the stability of the material falling process at each layer, the baffles 22 above the different distribution hoppers 21 have a phase difference in the circumferential direction and their tilt angles are different. This makes the guiding direction and constraint strength of the material by each baffle 22 different, which can regulate the local airflow disturbance and the material dispersion trend. The baffles 22 with different tilt angles work together to effectively restrict the material within their respective falling channels, avoiding crosstalk between the upper and lower layers of material under the action of airflow or inertia, thereby ensuring the orderliness and uniformity of the material flow during the multi-stage buffer material distribution process.

[0034] Please refer to Figure 7 When it is necessary to adapt to materials with different particle sizes or flowability, the size of the flow guide gap between adjacent baffles 22 can be changed by adjusting the tilt angle of the baffles 22. For this purpose, a connecting shaft is installed at the middle of the upper end of each baffle 22 located on the same horizontal plane. An adjusting ring 222 is rotatably sleeved on the outer circumference of the connecting shaft. Adjacent adjusting rings 222 are hinged together by a connecting rod 223. An adjusting screw 224 is rotatably installed on the outer side of one end of the adjusting ring 222. The adjusting screw 224 is threaded with the side wall of the buffer pipe 2. When the adjusting screw 224 is rotated, the axial displacement generated pushes the corresponding adjusting ring 222 to move axially. After being transmitted through the connecting rod 223, it drives all adjusting rings 222 in the same layer to move synchronously, thereby driving each baffle 22 to rotate around the connecting shaft, realizing the synchronous adjustment of the tilt angle of the entire layer of baffles 22. Thus, the flow guide gap can be flexibly adjusted to optimize the airflow suppression and falling constraint effect.

[0035] Please refer to Figure 8 and Figure 9To further improve the uniformity of material dispersion before entering the distribution hopper 21, mounting blocks 225 are evenly distributed along the length of the baffle plate 22 at its lower end. The lower end of the mounting blocks 225 is connected to a buffer swing rod 226 via a ball joint. During the material falling process, the buffer swing rod 226 can swing freely in multiple directions under the influence of material impact, gravity and airflow disturbance, dynamically disturbing and flexibly buffering the material flow passing through the baffle plate 22, effectively breaking up agglomerated particles and weakening the local concentrated falling trend, so that the material enters the next stage distribution hopper 21 more evenly and smoothly.

[0036] Please refer to Figure 2 and Figure 3 To achieve different speeds of rotation between adjacent upper and lower distribution hoppers 21, an external toothed ring 23 is fixedly fitted around the outer periphery of the distribution hopper 21 and rotatably connected to the buffer pipe 2. The distribution hopper 21 is rotatably connected to the buffer pipe 2, and a rotating gear 231 rotatably mounted on the outer wall of the buffer pipe 2 meshes with the outer side of the external toothed ring 23. When the rotating gear 231 rotates, it drives the external toothed ring 23 and the distribution hopper 21 fixed to it to rotate synchronously through meshing. The external toothed ring 23 and the rotating gear 231 corresponding to adjacent distribution hoppers 21 adopt different tooth ratios to form different transmission ratios, thereby ensuring that each distribution hopper 21 runs at different speeds under drive, providing a basis for dynamic staggered material distribution at the outlet.

[0037] Please refer to Figures 1-4 To achieve synchronous reverse rotation of adjacent upper and lower hoppers 21, a rotating shaft 232 is provided between adjacent upper and lower rotating gears 231. The rotating shaft 232 is fixedly connected to the lower rotating gear 231 and rotatably connected to the upper rotating gear 231. A bushing 233 is fixedly connected to the lower end of the upper rotating gear 231 and sleeved on the outside of the rotating shaft 232. Horizontal bevel gears 234 are fixedly fitted on both the bushing 233 and the outside of the rotating shaft 232. A vertical bevel gear 235 meshes between the upper and lower horizontal bevel gears 234. The vertical bevel gear 235 is rotatably mounted on the mounting frame 237. The mounting frame 237 is fixedly connected to the outer wall of the buffer pipe 2. The rotating shaft 232 at the bottom is connected to the output shaft of the drive motor 236. The drive motor 236 is mounted on the outer wall of the buffer pipe 2 through a support.

[0038] During operation, the drive motor 236 drives the bottom rotating shaft 232 to rotate. The rotating shaft 232 synchronously drives the rotating gear 231 and the horizontal bevel gear 234 fixed to it to rotate. The rotating gear 231 drives the corresponding external gear ring 23 and the distribution hopper 21 to rotate through meshing transmission. At the same time, the horizontal bevel gear 234 transmits power to another horizontal bevel gear 234 through the vertical bevel gear 235, which in turn drives the bushing 233 and the upper rotating gear 231 fixed to it to rotate in the opposite direction. The upper rotating gear 231 then drives its corresponding external gear ring 23 and the distribution hopper 21 through meshing, realizing synchronous reverse operation with the lower adjacent distribution hopper 21. Furthermore, the above transmission structure is repeatedly set between each adjacent distribution hopper 21, so that all the upper and lower adjacent distribution hoppers 21 can stably achieve reverse rotation, ensuring that the discharge port continuously forms dynamic misalignment during the movement, thereby effectively improving the uniformity and continuity of material falling.

[0039] In actual operation (use), the material is fed into the buffer pipe 2 by the upstream conveying device. After being stabilized and suppressed by the uppermost baffle plate 22, it falls into the top layer distribution hopper 21. Subsequently, the material falls sequentially through the discharge port at the bottom of each distribution hopper 21, passes through the guide gap of the next level baffle plate 22, and enters the lower layer distribution hopper 21. During the process, the baffle plate 22 plays a role in shielding, restraining, and preventing the material from scattering. At the same time, the drive motor 236 drives the lowermost rotating shaft 232 to rotate, which is driven by the horizontal bevel gear 234 and the vertical bevel gear 235. The meshing transmission of 35 enables the adjacent rotating gears 231 to rotate synchronously in opposite directions. Each rotating gear 231 drives the corresponding external gear ring 23 and the distribution hopper 21 to rotate. Due to the different transmission ratios of adjacent transmission pairs, each distribution hopper 21 operates at different speeds. Under the action of reverse speed rotation, the discharge port forms a dynamic misalignment. The material is continuously sheared and redistributed as it falls step by step. Finally, it enters the anti-grading device 1 in a uniform, planar form through the bottom distribution hopper 21 and the baffle plate 22, completing a stable and anti-grading feeding process.

[0040] Example 2, please refer to this example. Figure 10 - Figure 13 .

[0041] The difference between this embodiment and Embodiment 1 is that the discharge port here is a plurality of circular through holes 212 evenly distributed around the bottom circumference of the distribution hopper 21. From top to bottom, the circular through holes 212 of each distribution hopper 21 are offset radially from the outer circumference to the inner circumference. The inner bottom surface of the distribution hopper 21 is inclined toward its corresponding circular through hole 212, so that the material can smoothly slide to the discharge port under the action of gravity.

[0042] During operation, the rotating hopper 21 drives the circumferentially distributed circular through holes 212 to rotate synchronously, forming a continuous annular discharge trajectory. Due to the offset of the through hole positions and the difference in rotation speed between adjacent layers, the material is evenly dispersed during the dynamic falling process. The multiple rotating circular through holes 212 work together to form a dynamically expanding discharge surface, thereby achieving uniform material distribution in a planar form and effectively avoiding the accumulation or grading phenomenon caused by concentrated material discharge.

[0043] On the other hand, the present invention also provides a method for uniformly conveying materials in a winery, applicable to a uniform material conveying device in a winery, combined with... Figure 1 and Figure 2 This includes the following steps: Step 1: The material enters the buffer pipe 2 via the upstream conveying device. First, it passes through the uppermost baffle plate 22 for airflow suppression and initial flow stabilization. Then, it falls into the top layer distribution hopper 21. The material falls through the discharge port at the bottom of the distribution hopper 21, passes through the guide gap of the next level baffle plate 22, and enters the next layer distribution hopper 21. Step 2: Under the action of the upper and lower adjacent distribution hoppers 21 rotating in opposite directions at different speeds, the material is continuously dispersed through the dynamically staggered discharge port during the step-by-step falling process, forming a planar distribution and evenly transitioning to the next level distribution hopper 21. Step 3: After being regulated by the bottom distribution hopper 21 and the corresponding baffle plate 22, the material finally enters the anti-grading device 1 in a uniform and continuous planar form, completing the feeding of the anti-grading device.

Step 3: After being regulated by the bottom distribution hopper (21) and the corresponding baffle plate (22), the material finally enters the anti-grading device (1) in a uniform and continuous planar form, thus completing the feeding of the anti-grading device.
