Description

Technical Field

[0001] This utility model relates to a transportation or storage device, specifically a material distribution device that evenly distributes materials in a large silo and prevents material segregation. Background Technology

[0002] In industrial production, powdery and granular materials are typically stored in silos for easy access. For large silos with storage capacities of thousands or tens of thousands of tons, materials are usually only taken from a specific area within the silo at a time. Therefore, the uniformity of the material within the silo directly affects the stability of material storage and subsequent processing efficiency.

[0003] Traditional material distribution methods involve materials falling directly from the top of the silo or being transported directly to a large silo via pipelines. These methods have several problems: First, the material falls from a great height, generating significant dust that pollutes the environment, harms operator health, and wastes materials. Second, after falling onto the cone-shaped material surface, gravity causes coarse particles to settle at the bottom center of the silo, while fine particles tend to disperse or accumulate at the edges, resulting in segregation. This leads to uneven material composition in subsequent applications and can even affect subsequent production.

[0004] Patent application CN 118954122 A discloses an anti-segregation fabric spreading method and device. During the spreading process, the spreading mechanism rotates continuously around a vertical rotation center line. While rotating, the horizontal translation distance of the material relative to the rotation center line as it leaves the spreading mechanism is gradually adjusted, and the rotation speed of the spreading mechanism is gradually changed. This causes the material's trajectory within the hopper to move smoothly along a spiral path from the inside out or from the outside in, thus spreading the material layer by layer. The device and control method used in this spreading method are very complex, requiring continuous adjustment of the spreading mechanism's rotation speed. Furthermore, the material splashes during spreading, which can generate significant dust problems, especially for powder materials.

[0005] Patent CN 222539962 U discloses a cement material homogenization system. The system includes a material distribution silo with a material distribution plate installed inside. The material drop point of the feeding device corresponds to the material distribution plate, which has drop holes. A material distribution pipe, corresponding to the drop holes, is installed below the material distribution plate. A material throwing auger is installed inside the material distribution pipe, and a drive device for driving the auger is installed below the pipe. Multiple discharge ports are evenly spaced along the circumference of the material distribution pipe. A dust collection hood is fixed to the top of the silo via a bracket, and a suction pipe is installed on the top of the dust collection hood. This patent achieves more uniform material mixing through multi-stream diversion. During the diversion process, the material is thrown out by the auger, improving the uniformity of material mixing and also able to disperse larger agglomerates of similar materials. However, the auger requires a drive device, and the material thrown out by the auger can easily generate significant dust.

[0006] Patent CN 217263383 U discloses a pelletizing combustion material discharge device. This device includes a leveling component located within the material distribution hopper. The leveling component can flatten the tips of the falling mixed sintering material, thereby preventing the mixed sintering material from forming a pile-up shape and avoiding segregation caused by the pile-up effect. However, the leveling component has a complex structure, requires a motor drive, and also occupies a significant amount of material storage space. Utility Model Content

[0007] This invention provides a large-scale silo anti-segregation fabric distribution device, which solves the problems of complex structure and dust generation in existing anti-segregation fabric distribution methods.

[0008] The technical solution adopted by this utility model is: a large silo anti-segregation material distribution device, including a silo, a material distribution box on the top of the silo, the material distribution box having an inlet and at least two outlets, the outlets being directly connected to a discharge pipe or connected to the discharge pipe through an inclined pipe, the discharge pipe being suspended at different positions inside the silo, the lower end of the discharge pipe being an open bottom outlet, and the bottom outlet being close to the bottom plate of the silo, the side wall of the discharge pipe being vertically spaced at least two lateral outlets, each lateral outlet being located inside the silo, and the top of each lateral outlet being hinged with a cover plate, the cover plate being located outside the discharge pipe, the cover plate closing the lateral outlet under its own weight.

[0009] To improve the uniformity of the fabric when the material is discharged from the side outlet of the discharge pipe, the discharge pipe is further provided with at least two layers of side outlets in the vertical direction. Each layer of side outlets includes at least two side outlets. The side outlets of the same layer are arranged at the same height of the discharge pipe and are arranged at intervals in the circumferential direction of the discharge pipe.

[0010] The silo is generally circular in horizontal cross-section. In order to evenly arrange the discharge pipes in the silo, specifically: one discharge port of the distribution box is directly connected to a discharge pipe, which is located on the center line of the silo; at least three inclined pipes are evenly arranged downward along the radial direction of the distribution box, and the lower end of each inclined pipe is connected to the discharge pipe. The geometric body formed by the discharge pipes connected to the inclined pipes is a right prism.

[0011] To further improve the stability of the discharge pipes, at least one discharge pipe is also fixedly connected to the silo. For example, the discharge pipe near the side wall of the silo is fixedly connected to the side wall of the silo by a clamp.

[0012] The inclined pipe connects the distribution box and the discharge pipe. After the material enters the distribution box, it can automatically flow into the discharge pipe through the inclined pipe. Specifically, the inclined pipe is a chute.

[0013] To further improve the sealing effect of the cover plate on the side outlet, a support seat is also provided at the side outlet, and the cover plate is pressed against the support seat by its own weight.

[0014] To further improve the sealing effect of the side plate on the lateral outlet, the cover plate is arranged at an angle downwards when it is pressed against the support seat.

[0015] To ensure the cover plate is securely pressed against and closes the side outlet, a counterweight is further provided at the lower end of the cover plate.

[0016] The beneficial effects of this invention are as follows: Material is conveyed to the distribution box and then automatically enters the discharge pipe directly or automatically through an inclined pipe. Finally, the material falls into the silo through the discharge pipe. The discharge pipes are suspended at different positions within the silo, allowing material to be discharged from each pipe, thus ensuring even distribution within the silo. When the material level in the silo is below the bottom outlet of the discharge pipe, the side outlets are closed by a cover plate, and material is discharged from the bottom outlet into the silo. When the material level in the silo is above the bottom outlet of the discharge pipe, the bottom outlet is submerged under the material. As the material accumulates in the discharge pipe, the cover plate of the lowest side outlet above the material level is opened by the material, allowing discharge. The material's fall mainly or entirely occurs inside the discharge pipe, effectively suppressing dust diffusion. Compared to the method of discharging directly from the top of the silo, the internal environment of the silo is significantly improved, and the material particles are evenly distributed, effectively avoiding material segregation.

[0017] The large silo anti-segregation material distribution device uses a mechanical structure to achieve automatic material distribution without the need for complex electrical control. It is low in cost, has a low failure rate, is easy to install and maintain, and is suitable for distributing various powdery and granular materials in large silos. The number of discharge pipes, as well as the number and position of the lateral outlets of each discharge pipe, can be adjusted according to the silo size and material characteristics, and it has broad application prospects.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figure 1 As shown, the large-scale anti-segregation material distribution device of this utility model includes a silo 1, with a distribution box 2 at the top of the silo 1. The distribution box 2 has an inlet and at least two outlets. The outlets are directly connected to a discharge pipe 3 or connected to the discharge pipe 3 through an inclined pipe 4. The discharge pipe 3 is suspended at different positions inside the silo 1. The lower end of the discharge pipe 3 is an open bottom outlet 3-1, which is close to the bottom plate of the silo 1. The discharge pipe 3 is generally made of wear-resistant material, such as wear-resistant steel, with a thickness of about 8mm, which can withstand long-term erosion by materials.

[0023] The feed inlet of the distribution box 2 is used to receive centralized external materials. There is generally one feed inlet to facilitate centralized feeding into the distribution box 2. The distribution box 2 has multiple discharge outlets. After the materials enter the distribution box 2, they are discharged from each outlet. Materials in the distribution box 2 can either directly enter the discharge pipe 3 and then be discharged into the silo 1, or first enter the inclined pipe 4, then the discharge pipe 3, and finally be discharged into the silo 1. The discharge pipe 3 is generally arranged vertically, but can also be arranged inclined downwards. The lengths of the discharge pipes 3 and the lengths of the inclined pipes 4 can be equal or unequal, as long as the discharge pipes 3 are evenly distributed within the silo 1. The inclined pipes 4 are arranged inclined downwards, serving to connect the distribution box 2 and the discharge pipes 3, while also distributing the discharge pipes 3 within the silo. After entering the distribution box 2, the materials, by their own weight, can automatically flow through the inclined pipes 4 into the discharge pipe 3. The inclined pipe 4 can be arranged inside or outside the silo 1. To avoid the material distribution box 2 and the inclined pipe 4 being visible inside the silo 1, the material distribution box 2 and the inclined pipe 4 are generally arranged outside the material box.

[0024] The inclined pipe 4 can be either closed or open. In a closed type, only both ends of the inclined pipe 4 are open and connected to the discharge port of the distribution box 2 and the upper end of the discharge pipe 3, respectively, and the inner cavity of the inclined pipe 4 is not directly connected to the atmospheric environment. In an open type, both ends of the inclined pipe 4 are open and connected to the discharge port of the distribution box 2 and the upper end of the discharge pipe 3, respectively, and the inner cavity of the inclined pipe 4 is directly connected to the atmospheric environment. For example, the inclined pipe 4 can be a chute.

[0025] For large silos, the horizontal cross-section of silo 1 is generally circular, meaning the inner cavity of silo 1 is cylindrical. To facilitate material discharge from silo 1, the bottom of the inner cavity is a frustum-shaped cone, wider at the top and narrower at the bottom. Figure 1 As shown. The following provides a specific embodiment of the distribution of the discharge pipe 3 within the hopper 1. See also... Figure 1One of the discharge ports of the distribution box 2 is directly connected to a discharge pipe 3. The discharge pipe 3 is located on the center line of the silo 1, that is, the discharge pipe 3 is directly connected to the discharge port at the bottom of the distribution box 2. At the same time, at least three inclined pipes 4 are evenly arranged in the radial direction of the distribution box 2. The length and inclination angle of each inclined pipe 4 are equal. The lower end of each inclined pipe 4 is connected to the discharge pipe 3. The geometric body formed by the discharge pipes 3 connected to the inclined pipes 4 is a right prism.

[0026] The discharge pipe 3 can be suspended inside the hopper 1, in which case the discharge pipe 3 does not contact the inner wall of the hopper 1 and is not relatively fixed. To improve the stability of the discharge pipe 3, it can also be fixedly connected to the hopper 1, that is, the discharge pipe 3 is fixedly connected to the inner wall of the hopper 1. When the discharge pipe 3 is fixedly connected to the hopper 1, it can be that some of the discharge pipes 3 are fixedly connected to the hopper 1 separately, or all of the discharge pipes 3 are fixedly connected to the hopper 1. For example, see... Figure 1 The discharge pipe 3 near the side wall of silo 1 is fixedly connected to the side wall of silo 1, while the discharge pipe 3 away from the side wall of silo 1 is not fixedly connected to silo 1. When the discharge pipe 3 is fixedly connected to the side wall of silo 1, the discharge pipe 3 can be fixedly connected to the side wall of silo 1 through a clamp to ensure a stable connection.

[0027] The lower end of the discharge pipe 3 is a bottom outlet 3-1. The lower end of the discharge pipe 3 is either fixedly connected to the bottom plate of the silo 1, suspended in the air, or abuts against but is not fixed to the bottom plate of the silo 1. The bottom outlet 3-1 at the lower end of the discharge pipe 3 is close to the bottom plate of the silo 1, which reduces the impact of materials on the bottom and surface of the silo 1, thereby reducing dust generation during material distribution. At least two side outlets 3-2 are vertically spaced along the side wall of the discharge pipe 3. Each side outlet 3-2 is located inside the silo 1, and a cover plate 5 is hinged to the top of each side outlet 3-2. The cover plate 5 is located outside the discharge pipe 3 and closes the side outlet 3-2 under its own weight. When the discharge pipe 3 is arranged vertically, the axis of rotation of the cover plate 5 is horizontal. The cover plate 5 can be hinged to the top of the side outlet 3-2. The cover plate 5 is generally made of metal plate, such as steel plate with a thickness of 5mm, to ensure sufficient strength. The hinge is made of stainless steel to prevent the cover plate 5 from being affected by corrosion.

[0028] Both the bottom outlet 3-1 and the side outlet 3-2 are used to distribute material into the hopper 1. The material is conveyed to the distribution box 2, and first automatically enters the discharge pipe 3 directly or automatically through the inclined pipe 4. Finally, the material falls into the hopper 1 through the discharge pipe 3, completing the distribution. When the material level in the hopper 1 is below the bottom outlet 3-1 of the discharge pipe 3, the side outlet 3-2 is closed by the cover plate 5, and the material is discharged from the bottom outlet 3-1 into the hopper 1. When the material level in the hopper 1 is above the bottom outlet 3-1 of the discharge pipe 3, the bottom outlet 3-1 is submerged under the material. As the material accumulates in the discharge pipe, the cover plate 5 of the lowest side outlet 3-2 above the material level is opened by the material, and the material is discharged. The side outlet 3-2 is submerged under the material. As the material accumulates in the discharge pipe, the cover plate 5 of the lowest side outlet 3-2 above the material level is opened by the material, and the material is discharged. Throughout the fabric distribution process, the material flows orderly through the bottom outlet 3-1 and side outlet 3-2 of the discharge pipe 3, avoiding the violent impact of direct material falling and reducing dust dispersion. At the same time, the material diffuses outward from the side outlet 3-2, and materials of different particle sizes are evenly distributed in various areas of the hopper 1, improving the uniformity of fabric distribution.

[0029] Lateral outlets 3-2 are arranged vertically at intervals along the sidewall of the discharge pipe 3. To improve the uniformity of material distribution, the discharge pipe 3 is provided with at least two layers of lateral outlets 3-2 vertically, each layer including one or more lateral outlets 3-2, wherein multiple layers include two or more. When each layer includes one lateral outlet 3-2, the lateral outlet 3-2 faces the side of the hopper 1 that can store material, that is, the lateral outlet 3-2 faces away from the sidewall of the hopper 1. When each layer includes multiple lateral outlets 3-2, the lateral outlets 3-2 of the same layer are arranged at the same height of the discharge pipe 3 and are arranged circumferentially at intervals along the discharge pipe 3, and preferably at equal intervals, so that material can be discharged from the periphery of the discharge pipe 3, such as... Figure 2 As shown.

[0030] The discharge pipe 3 is generally a round pipe. To improve the sealing effect of the cover plate 5 on the side outlet 3-2, the side outlet 3-2 is also equipped with a support seat 6. The support seat 6 is adapted to the cover plate 5, and the cover plate 5 is pressed against the support seat 6 by its own weight. In order to make the cover plate 5 firmly pressed against the side outlet 3-2, a counterweight 7 is also provided at the lower end of the cover plate 5. For example, the counterweight 7 is an iron block welded to the cover plate 5. To further improve the sealing effect of the side plate on the side outlet 3-2, when the cover plate 5 is pressed against the support seat 6, the cover plate 5 is arranged at an angle downward.
