Description

Technical Field

[0001] This application relates to the field of discharge buffer devices, and particularly to a discharge buffer device. Background Technology

[0002] In industrial production processes involving malt processing, such as beer brewing, malt augers are commonly used for conveying malt. Due to the relatively high conveying speed of the auger and the weight and fluidity of the malt, it tends to clump when discharged from the outlet under the auger's power. When the malt falls directly from the outlet, it causes significant impact on the receiving or transporting equipment below. This impact not only generates considerable noise, affecting the sanitary environment, but can also damage the receiving or transporting equipment, shortening its lifespan and increasing maintenance costs. Furthermore, it hinders the smooth transport of malt and the precise control of subsequent processing techniques. Utility Model Content

[0017] A support rod connects the arch-breaking structure and the segmentation structure; the support rod extends along the central axis inside the vertical tube.

[0018] In one exemplary embodiment, the sidewall of the vertical tube is provided with a plurality of sieve holes, the sieve holes are in communication with the interior of the vertical tube, and the positions of some of the sieve holes correspond to the arch-breaking structure along the radial direction of the vertical tube.

[0019] In one exemplary embodiment, the vertical tube section has the sieve holes on the side wall between the arch-breaking structure and the segmentation structure.

[0020] In one exemplary embodiment, the sieve holes are strip-shaped;

[0021] The sieve holes extend along the outer periphery of the mounting tube; a plurality of the sieve holes are arranged at vertical intervals.

[0022] The extension length of the sieve holes is less than half the circumference of the vertical tube.

[0023] In one exemplary embodiment, the side wall of the mounting pipe is provided with an insertion hole, the insertion hole being located between the inlet of the mounting pipe and the arch-breaking structure, and a flow regulating plate is detachably inserted into the insertion hole.

During the process of the material passing through the vertical pipe section, it can sequentially pass through the arch-breaking structure and the dividing structure under the action of gravity. The conical tip of the arch-breaking structure can first break up the clumps of material, thereby evenly dispersing the clumps and reducing their accumulation.

[0041] Figure 1 A schematic diagram of the discharge buffer device of this application is shown. Figure 2 A cross-sectional view of the discharge buffer device of this application is shown. Figure 3A cross-sectional front view of the discharge buffer device of this application is shown. Figure 4 The diagram shows the structural schematics of the arch-breaking structure 2 and the segmentation structure 3 of this application.

[0042] Reference Figures 1 to 4 The discharge buffer device includes an installation pipe 1, an arch-breaking structure 2, and a segmentation structure 3.

[0043] The interior of the mounting pipe 1 is axially continuous, with inlet 11 and outlet 12 at its two axial ends. The inlet 11 of the mounting pipe is connected to the discharge port of an external device to receive material discharged from the discharge port. After entering the mounting pipe 1, the material is conveyed axially along its interior and finally discharged from the outlet 12. The mounting pipe 1 includes a vertically extending vertical pipe section 14, the interior of which is vertically continuous, and the outlet 12 of the mounting pipe 1 is formed at the bottom opening of the vertical pipe section 14.

[0044] The arch-breaking structure 2 and the segmentation structure 3 are arranged alternately from top to bottom inside the vertical tube section 14. As the material passes through the vertical tube section 14, it can pass through the arch-breaking structure 2 and the segmentation structure 3 in sequence under the action of gravity.

[0045] The top of the arch-breaking structure 2 is provided with a conical surface 21, the outer diameter of which gradually increases downwards. The outer periphery of the conical surface 21 is spaced apart from the inner peripheral wall of the vertical tube 14. Under the action of gravity, the material falls downwards onto the arch-breaking structure 2. The tip of the conical surface 21 of the arch-breaking structure 2 can first break up the clumps of material. After breaking up the clumps, the material is evenly dispersed in all directions along the conical surface 21 at an angle downwards, and continues to fall downwards from the gap between the outer periphery of the conical surface 21 and the inner peripheral wall of the vertical tube 14, reducing the accumulation of clumps.

[0046] The dividing structure 3 is located at intervals below the arch-breaking structure 2. The dividing structure 3 includes multiple dividing elements 31, which form multiple vertically extending and spaced material passage channels 32. The dividing elements 31 are used to buffer and divide the material so that the divided material can pass downward through the material passage channels 32. The material dispersed by the arch-breaking structure 2 enters the space between the arch-breaking structure 2 and the dividing structure 3 for buffering, preventing the dispersed material from clumping again. The dividing elements 31 can block and buffer the material after passing through the arch-breaking structure 2. Under the action of gravity, the dividing elements 31 can further disperse the material by dividing it, and after passing through the material passage channels 32, it is discharged from the bottom opening of the vertical pipe section 14.

[0047] This application uses the arch-breaking structure 2 to first evenly disperse the clumped material, and then uses the dividing structure 3 to further divide and disperse the material, reducing the accumulation of clumps, thereby reducing the impact on the external receiving equipment or transportation device below, reducing noise, improving the on-site environmental hygiene and the service life of the external receiving equipment or transportation device, and reducing the cost of manual cleaning.

[0048] The installation pipe 1 of this application has an axially continuous interior, with an inlet 11 and an outlet 12 at its two axial ends. The inlet 11 of the installation pipe 1 is used to connect with the discharge port of an external device to receive the material output from the discharge port. After entering the installation pipe 1, the material is conveyed axially along the interior of the installation pipe 1 and finally discharged from the outlet 12 of the installation pipe 1.

[0049] The installation pipe 1 includes a vertical pipe section 14, which extends vertically and is vertically continuous inside. The vertical pipe section 14 is a vertical pipe fitting, ensuring that after the material enters the vertical pipe section 14, it passes through the vertical pipe section 14 under the action of gravity and falls into the external receiving equipment or transport device located below.

[0050] The mounting pipe 1 also includes an elbow section 13, the interior of which is axially continuous. One axial end opening of the elbow section 13 is connected to the top opening of the vertical pipe section 14. The elbow section 13 and the vertical pipe section 14 are connected sequentially. The outlet 12 of the mounting pipe 1 is formed at the other axial end opening of the elbow section 13 to receive material from the discharge port. The outlet 12 of the mounting pipe 1 is formed at the bottom opening of the vertical pipe section 14. The elbow section 13 is a curved pipe fitting, which can change the material conveying direction so that the material output from the discharge port can smoothly enter the vertical pipe section 14 through the elbow section 13. In this embodiment, the elbow section 13 is bent at 90°. Alternatively, the elbow section 13 can be bent at other angles, as long as it can connect the discharge port of the external equipment and the top opening of the vertical pipe section 14.

[0051] The vertical pipe section 14 and the elbow pipe section 13 can be made of steel pipe. The vertical pipe section 14 and the elbow pipe section 13 can be connected by welding. The cross-sectional shape of both the vertical pipe section 14 and the elbow pipe section 13 is circular.

[0052] In this embodiment, the material can be wheat lees. The wheat lees in the external equipment are conveyed horizontally under the push of the auger. The elbow pipe section 13 can be connected to the discharge port of the external equipment through a structure such as a flange, so that the wheat lees can pass through the elbow pipe section 13 and the vertical pipe section 14 in sequence and be discharged.

[0053] The top of the arch-breaking structure 2 of this application is provided with a conical surface 21. The apex of the conical surface 21 faces upward, and the outer diameter of the conical surface 21 gradually increases downward. The outer periphery of the conical surface 21 is spaced apart from the inner peripheral wall of the vertical tube section 14. The apex of the conical surface 21 can break up the clumps of material falling downward. The shape of the conical surface 21 has a certain guiding property. The broken material pieces are guided downward by the surface of the conical surface and dispersed, so that the dispersed material can smoothly pass through the gap between the conical surface 21 and the vertical tube section 14 and continue to fall downward. Specifically, the conical surface 21 in this embodiment is a circular conical surface 21, which makes the material disperse more evenly on the conical surface 21. In addition, the conical surface 21 can also be a finger-shaped pyramidal surface 21.

[0054] Furthermore, the taper of the conical surface 21 is 30° to 45°. The taper of the conical surface 21 should not be too small to ensure the effect of breaking up and dispersing agglomerated materials, and the taper of the conical surface 21 should not be too large to avoid excessive resistance to material conveying caused by a large angle of the conical surface 21, which would result in material accumulation and wear of the breaking structure 2.

[0055] Furthermore, the central axis of the conical surface 21 coincides with the central axis inside the vertical tube section 14. The conical surface 21 of the arch-breaking structure 2 is located in the middle of the vertical tube section 14, and its central axis coincides with the central axis inside the vertical tube section 14. The conical surface 21 is positioned on the path of the falling agglomerated material, thus more effectively intercepting and breaking up the agglomerated material. Moreover, the spacing between the outer periphery of the conical surface 21 and the inner peripheral wall of the vertical tube section 14 can be more uniform, reducing the accumulation of broken material on the conical surface 21.

[0056] Furthermore, the outer diameter of the cone base of the conical surface 21 is 25% to 35% of the inner diameter of the vertical tube section 14. The outer diameter of the cone base of the conical surface 21 cannot be too small to ensure its ability to disperse material, while it cannot be too large to ensure that material can fall smoothly down the conical surface 21, preventing material accumulation and compression between the outer wall of the conical surface 21 and the inner wall of the vertical tube section 14. In a specific embodiment, the outer diameter of the cone base of the conical surface 21 can be 1 / 3 of the inner diameter of the vertical tube section 14.

[0057] Furthermore, the arch-breaking structure 2 is cone-shaped. Specifically, the arch-breaking structure 2 is a cone, which improves its strength and enables it to withstand the continuous impact of conveying agglomerated materials. Alternatively, the arch-breaking structure 2 can also be a hollow cone structure.

[0058] Reference Figures 2 to 4 The segmentation structure 3 of this application is spaced below the arch-breaking structure 2, so that there is a gap between the segmentation structure 3 and the arch-breaking structure 2. After the material is dispersed by the arch-breaking structure 2, it can first enter the space between the arch-breaking structure 2 and the segmentation structure 3 for buffering, so as to avoid the material from accumulating and clumping, so that the material can pass through the segmentation structure 3 smoothly.

[0059] Furthermore, the segmentation structure 3 includes a plurality of segmenting members 31, wherein the plurality of segmenting members 31 in this application refers to two or more segmenting members 31. The plurality of segmenting members 31 extend radially outward from the central axis of the vertical tube section 14 at intervals and connect to the inner peripheral wall of the vertical tube section 14, and a material passage 32 is formed between the opposite sides of two adjacent segmenting members 31 and the inner wall of the vertical tube section 14.

[0060] The dividing members 31 extend radially along the vertical tube section 14, such that the inner sides of the multiple dividing members 31 are interconnected and located on the central axis of the vertical tube section 14, and the outer sides of the multiple dividing members 31 are connected to the inner peripheral wall of the vertical tube section 14. The multiple radially arranged dividing members 31 can further and uniformly cut the material dispersed to the surrounding area by the conical surface 21. A fan-shaped material passage 32 can be formed between two adjacent dividing members 31 and the inner wall of the vertical tube section 14. The material passage 32 is wider on the side closer to the vertical tube section 14 to facilitate the passage of material.

[0061] Specifically, Figure 4 The illustrated dividing structure 3 includes four dividing elements 31, which extend radially to form a cross-shaped frame. In other embodiments, the dividing structure 3 may include two, three, five, or other dividing elements 31. Preferably, the dividing structure 3 includes three to six dividing elements 31, with at least three dividing elements 31 arranged radially to improve the overall structural strength of the dividing structure 3. Furthermore, the number of dividing elements 31 should be six or less to avoid clogging the material due to excessive numbers of dividing elements 31, ensuring that the material can pass smoothly through the dividing structure 3.

[0062] In other embodiments, the multiple dividing members 31 may be staggered or arranged in parallel with each other, as long as the dividing members 31 or the inner wall of the vertical tube 14 can form a material passage 32 for material to pass through.

[0063] Furthermore, the dividing element 31 is a vertical plate. When material moves onto the dividing element 31, it can be divided by the top edge of the dividing element 31. The vertical plate structure results in a smaller thickness for the dividing element 31, which can disperse the material and reduce obstruction and accumulation. In addition, the dividing element 31 can also be a blade with the cutting edge facing upwards, or a rod, etc. Multiple dividing elements 31 can be connected and fixed to the inner wall of the vertical tube section 14 by welding.

[0064] Furthermore, the spacing between adjacent dividing members 31 is the same. Specifically, the included angle between adjacent dividing members 31 is the same, which enables more uniform dispersion of material within the vertical tube section 14 and reduces localized material accumulation. In other embodiments, the included angle between adjacent dividing members 31 may also be different.

[0065] Furthermore, the discharge buffer device includes at least two vertically spaced dividing structures 3. These at least two dividing structures 3 are arranged vertically spaced inside the vertical tube section 14, enabling them to sequentially divide the material, further dispersing it and reducing the impact of falling material on external receiving equipment or transport devices.

[0066] Specifically, in two adjacent upper and lower dividing structures 3, the dividing element 31 of one dividing structure 3 is vertically aligned with the material passage 32 of the other dividing structure 3. The dividing elements 31 of the two dividing structures 3 are staggered, so that after the material divided by the upper dividing structure 3 falls from the material passage 32, it can impact the dividing element 31 of the lower dividing structure 3 for further division, thereby improving the dispersion effect of the material.

[0067] In this embodiment, the discharge buffer device includes a segmentation structure 3. In practice, the number of segmentation structures 3 needs to be determined based on factors such as the degree of material agglomeration, the length that the vertical pipe section 14 can be installed, and economic efficiency. This embodiment does not impose specific limitations on this.

[0068] Furthermore, the vertical distance between the bottom of the arch-breaking structure 2 and the top of the segmentation structure 3 is greater than 200mm. Because the distance between the outer periphery of the conical surface 21 of the arch-breaking structure 2 and the inner peripheral wall of the vertical tube 14 tends to decrease from top to bottom, by setting a certain vertical distance between the arch-breaking structure 2 and the segmentation structure 3, it is ensured that the material can be buffered after passing through the arch-breaking structure 2, and will not be directly blocked and cut by the segmentation structure 3, thereby reducing the phenomenon of material accumulating and agglomerating again.

[0069] A support rod 4 connects the arch-breaking structure 2 and the segmentation structure 3. The support rod 4 connects the arch-breaking structure 2 and the segmentation structure 3, so that the arch-breaking structure 2, the support rod 4 and the segmentation structure 3 form a whole, realizing the installation and fixation of the arch-breaking structure 2.

[0070] Furthermore, the support rod 4 extends along the central axis inside the vertical tube section 14. Specifically, the top end of the support rod 4 is connected to the bottom center of the arch-breaking structure 2, and the bottom end of the support rod 4 is connected to the top center of the segmented structure 3, i.e., at the position where multiple segmented pieces 31 are interconnected, thereby improving the installation stability of the arch-breaking structure 2. The support rod 4 can be connected to the arch-breaking structure 2 or the segmented structure 3 by welding or other methods.

[0071] Furthermore, the side wall of the vertical tube section 14 is provided with a plurality of sieve holes 141, which are connected to the interior of the vertical tube section 14, and the positions of some of the sieve holes 141 correspond to the arch-breaking structure 2 along the radial direction of the vertical tube section 14.

[0072] When a large amount of material is fed into the vertical pipe section 14 at once, causing a large amount of lees to accumulate at the arch-breaking structure 2, some of the lees will be squeezed out and fall from the screen. This prevents accumulation at the arch-breaking structure 2, providing a safe pressure relief and reducing the load on the auger. Furthermore, the design of the screen holes 141 allows for convenient direct rinsing of the interior of the vertical pipe section 14 and the arch-breaking structure 2 within it using an external water pipe during cleaning, preventing the lees from remaining inside for extended periods and causing mold and decay.

[0073] Furthermore, the vertical pipe section 14 has screen holes 141 on the side wall between the arch-breaking structure 2 and the dividing structure 3. The screen holes 141 can also safely relieve pressure at the position between the arch-breaking structure 2 and the dividing structure 3, reducing material accumulation above the dividing structure 3. In addition, the screen holes 141 can also facilitate external water pipes to clean the position between the arch-breaking structure 2 and the dividing structure 3, improving the cleaning effect.

[0074] Specifically, the sieve holes 141 in this application are strip-shaped. Multiple strip-shaped sieve holes 141 increase the area of ​​the sieve holes 141, further improving the safety pressure relief effect.

[0075] Furthermore, the strip-shaped screen holes 141 extend along the outer periphery of the mounting tube 1. Multiple screen holes 141 are arranged vertically at intervals. The multiple screen holes 141 can correspond to the top positions of the arch-breaking structure 2 and the dividing structure 3 vertically, and can play a pressure relief effect when the material passes over the arch-breaking structure 2 and the dividing structure 3. The vertically adjacent strip-shaped screen holes 141 are arranged at intervals, and the extension direction of the screen holes 141 is perpendicular to the falling direction of the material, which can also prevent the material from being squeezed out along the extension direction of the screen holes 141.

[0076] Furthermore, the extension length of the sieve hole 141 is less than half the circumference of the vertical tube portion 14. This is to avoid the sieve hole 141 being too long and affecting the strength of the vertical tube portion 14. Without considering the impact on the vertical tube portion 14, the circumferential length of the sieve hole 141 can also be more than half the circumference of the vertical tube portion 14. In practice, the specific circumferential dimension of the sieve hole 141 along the vertical tube portion 14 needs to be determined based on the circumference of the vertical tube portion 14.

[0077] The vertical dimension of the sieve aperture 141 in this application is 25mm to 35mm, and the circumferential dimension of the sieve aperture 141 along the vertical tube portion 14 is 90mm to 110mm.

[0078] In addition, the strip-shaped sieve holes 141 can also extend along the axial direction of the mounting tube 1, and two adjacent sieve holes 141 are spaced apart along the circumference of the mounting tube 1.

[0079] In other embodiments, the sieve hole 141 can also be round, polygonal, or other shapes. Multiple sieve holes 141 are spaced apart, which can relieve pressure and prevent materials from falling directly from the sieve hole 141.

[0080] Furthermore, the side wall of the installation pipe 1 is provided with an insertion hole 142, located between the inlet 11 of the installation pipe 1 and the arch-breaking structure 2. A flow regulating plate 5 is detachably inserted into the insertion hole 142. The flow regulating plate 5 can move radially relative to the installation pipe 1 to adjust the insertion depth of the flow regulating plate 5 into the installation pipe 1, thereby regulating the material flow rate in the installation pipe 1. When the material flow rate is small, the flow regulating plate 5 can be used to adjust the width of the channel through which the material passes inside the installation pipe 1, thereby buffering and intercepting small flow rates of material. When the material flow rate is large, the flow regulating plate 5 can be removed from the installation pipe 1.

[0081] The flow regulating plate 5 is slidably connected to the mounting pipe 1 in the radial direction. Specifically, the flow regulating plate 5 and the outer wall of the mounting pipe 1 can be connected by screws and screw seats. The screws are inserted in a direction parallel to the radial extension of the mounting pipe 1. When adjusting the screws, the flow regulating plate 5 can be moved radially relative to the mounting pipe 1.

[0082] Furthermore, the insertion hole 142 is provided on the side wall of the vertical pipe section 14. The insertion hole 142 is strip-shaped and extends along the outer periphery of the vertical pipe section 14. The flow regulating plate 5 can regulate the material flow rate within the vertical pipe section 14, avoiding the flow regulating plate 5 being directly subjected to a large impact force from the material because it is located at the inlet 11 of the mounting pipe 1.

[0083] In this embodiment, the width of the insertion hole 142 along the axial direction of the mounting pipe 1 matches the thickness of the flow regulating plate 5. The matching size of the insertion hole 142 and the thickness of the flow regulating plate 5 ensures that the flow regulating plate can be stably secured within the insertion hole 142. Furthermore, the width of the flow regulating plate 5 can match the diameter of the mounting pipe 1, improving the buffering and retention effect of the flow regulating plate 5 on materials.

This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein.
