Description

Technical Field

[0001] This utility model relates to the field of silo technology, specifically to an umbrella-shaped material distributor for silos. Background Technology

[0002] As a core piece of equipment for temporary storage and turnover of materials, the uniformity of material distribution within a silo directly affects its space utilization rate. However, in actual use, silos commonly suffer from uneven material distribution. Bulk materials are typically conveyed to the feed inlet above the silo by a conveyor. Under their own gravity, the materials fall into the silo. Due to the material's fluidity and concentrated falling trajectory, they naturally accumulate in the center of the silo, forming a cone-shaped accumulation. This concentration of material in the central area makes it difficult to effectively utilize the silo's edge areas, resulting in significant waste of storage space. Currently, this problem is often addressed by reducing the diameter of the silo and increasing its height. However, increasing the silo height increases the pressure on the silo walls, not only increasing equipment costs but also potentially affecting the quality of the material at the bottom of the silo.

[0003] Therefore, it is necessary to propose an umbrella-shaped material distributor for silos to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved The purpose of this utility model is to provide an umbrella-shaped material distributor for silos, so as to solve the problem mentioned in the background art that the material accumulates in the middle of the silo and the silo space utilization rate is low.

[0005] (II) Technical Solution To achieve the above objectives, this utility model is implemented through the following technical solution: an umbrella-shaped material distributor for silos, comprising an umbrella-shaped plate, a rotating shaft fixedly connected to the axis of the umbrella-shaped plate, the rotating shaft being driven to rotate by a motor; an arc-shaped edge is fixedly connected to the edge of the umbrella-shaped plate, the side of the arc-shaped edge close to the umbrella-shaped plate being tangent to the circumferential edge of the umbrella-shaped plate, and the side of the arc-shaped edge away from the umbrella-shaped plate bending outwards towards the umbrella-shaped plate.

[0006] Preferably, the motor is a geared variable frequency motor.

[0007] Preferably, one end of the rotating shaft extends through to the outside of the umbrella-shaped plate and is connected to the output shaft of the motor for transmission.

[0008] Preferably, an annular frame is fixedly connected to the inner side of the umbrella-shaped plate, and the annular frame is fixedly connected to the rotating shaft through a bracket.

[0009] Preferably, there are multiple supports, and the multiple supports are evenly distributed along the circumference of the annular frame.

[0010] Preferably, the outer sides of both the umbrella-shaped plate and the arc-shaped edge are provided with a friction-enhancing layer.

[0011] (III) Beneficial Effects Compared with the prior art, the present invention provides an umbrella-shaped material distributor for silos, which has the following advantages: 1. The silo uses an umbrella-shaped material distributor. By setting the umbrella-shaped plate and the arc-shaped edge, it can throw the material out and avoid the material from accumulating in the middle of the silo. At the same time, by adjusting the rotation speed of the umbrella-shaped plate, the throwing distance of the material can be controlled, so as to make the material distribution more uniform.

[0012] 2. The silo uses an umbrella-shaped material distributor. By placing the motor on the outside of the silo, the dust generated during the material falling process can be prevented from affecting the motor operation, thus ensuring its stable operation. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Please see Figure 1-3 As shown, an umbrella-shaped material distributor for silos includes an umbrella-shaped plate 4. A rotating shaft 6 is fixedly connected to the axis of the umbrella-shaped plate 4, and the rotating shaft 6 is driven to rotate by a motor 1. An arc-shaped edge 9 is fixedly connected to the edge of the umbrella-shaped plate 4. The side of the arc-shaped edge 9 near the umbrella-shaped plate 4 is tangent to the circumferential edge of the umbrella-shaped plate 4, and the side of the arc-shaped edge 9 away from the umbrella-shaped plate 4 bends outward from the umbrella-shaped plate 4. Specifically, one end of the rotating shaft 6 passes through to the outside of the umbrella-shaped plate 4 and is connected to the output shaft of the motor 1 for transmission. The motor 1 is positioned above the umbrella-shaped plate 4 to facilitate the installation and arrangement of the motor 1 and the umbrella-shaped plate 4.

[0017] In use, the motor 1 is fixed to the outside of the top feed inlet 3 of the silo 5, and the umbrella-shaped plate 4 is placed inside the top feed inlet 3 of the silo 5. Positioning the motor 1 above the silo 5 prevents dust caused by falling materials from affecting its operation. When material is conveyed to the silo 5 via the conveyor 2, the material falls to the top of the umbrella-shaped plate 4, where it is evenly dispersed. The motor 1 drives the umbrella-shaped plate 4 to rotate, and under centrifugal force, combined with the arc-shaped edge 9, the material is accelerated and thrown out, preventing it from accumulating in a cone shape within the silo 5 and improving space utilization. By setting the arc-shaped edge 9 to reduce the slope of the umbrella-shaped plate 4, the material is thrown out at a near-horizontal angle, increasing the controllability of the material distribution distance. Using this material distributor can reduce the silo height, increase the silo diameter, and fully utilize the silo space.

[0018] Specifically, motor 1 is a geared variable frequency motor. By adjusting the speed of motor 1, the rotation speed of umbrella-shaped plate 4 can be controlled, so that the material can obtain different centrifugal forces and initial throwing speeds to adapt to materials with different physical properties and achieve control over the throwing distance, making the fabric more uniform.

[0019] To improve its structural strength, an annular frame 7 is fixedly connected to the inner side of the umbrella-shaped plate 4. The annular frame 7 is fixedly connected to the rotating shaft 6 via a bracket 8. The annular frame 7 and the bracket 8 provide auxiliary support for the umbrella-shaped plate 4, preventing it from deforming under stress. Specifically, there are multiple brackets 8, which are evenly distributed around the circumference of the annular frame 7. By evenly distributing the multiple brackets 8, the mass distribution is uniform, achieving dynamic balance.

[0020] Specifically, both the umbrella-shaped plate 4 and the outer side of the arc-shaped edge 9 are provided with a friction-enhancing layer. By setting the friction-enhancing layer, it is ensured that the material can obtain sufficient throwing speed, thereby making its landing point more accurate and uniform. Specifically, the friction-enhancing layer has regular or irregular textures formed by knurling, embossing, or shot peening processes.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
