Description

Technical Field

[0001] The utility model relates to the technical field of powder conveying equipment, in particular to a powder storage tank for powdery materials. Background Art

[0002] Sodium fluoride, with the chemical formula NaF, is in the form of white crystals or powder. In the production process of sodium fluoride, the wet powder after being centrifuged and dried needs to be conveyed to a dryer for drying. However, due to the extremely fine and wet particles of sodium fluoride powder, it is extremely easy to be blocked during the conveying process, and manual assistance has to be relied on to clean the blockage, which seriously affects the automation process of the production line.

[0003] To solve the problem of powder blockage, there are various solutions on the market. For example, the utility model patent with the patent number: ZL202222598614.7 and the patent name: Powder Material Storage Device discloses a transmission shaft and a spiral fan blade. A metal ball is arranged on the transmission shaft. The spiral fan blade rotates to push the powder in the discharge pipe downward. The metal ball rotates and contacts and impacts the force receiving block to shake off the powder adhering to the inner wall of the device.

[0004] However, it is found in the actual use process that due to the limited coverage of the spiral fan blade, it is difficult to drive the powder to flow comprehensively. When the powder is relatively wet, it is easy to form lumps and has poor fluidity. The spiral fan blade can only drive the nearby powder to flow and cannot achieve the purpose of powder conveying. Moreover, the metal ball is easy to wind around the transmission shaft and cannot shake off the powder adhering to the inside of the device. Summary of the Invention

[0005] To solve the above problems, the present application provides a powder storage tank for powdery materials, which is provided with a tank body. The tank body is a cylindrical structure with an open upper part. An outlet is arranged on the bottom plate of the tank body. A rotating plate is horizontally arranged above the bottom plate of the tank body. The rotating plate is connected to a rotating driver. The outer edge of the rotating plate is evenly distributed with dialing teeth, and the dialing teeth are arranged radially with the center of the rotating plate as the base point.

[0006] In one embodiment, a conical cap is fixedly arranged on the rotating plate, and the inside of the conical cap is a hollow structure.

[0007] In one embodiment, an outlet cap is fixedly arranged inside the tank body. The outlet cap is located above the outlet. There is a certain gap between the outlet cap and the bottom plate of the tank body, and the dialing teeth can pass through the gap.

[0008] In one embodiment, a tank lining is fixedly arranged on the inner wall of the tank body. The upper end of the tank lining has a large opening and the lower end has a small opening.

[0009] In one embodiment, the rotating driver is a servo motor.

[0010] The beneficial effects of the present utility model are as follows:

[0011] A powder material storage tank of the present application is provided with material pushing teeth. The material pushing teeth are radially and evenly distributed with the center of the rotating plate as the base point. When the material pushing teeth rotate, they can cover a large area at the bottom of the tank body. During the operation of the equipment, the rotating driver drives the rotating plate and the material pushing teeth to rotate, continuously pushing the powder material at the bottom of the tank body from the surrounding area to the position of the discharge port. During the rotation process, the powder material moves downward under the action of gravity, and the material pushing teeth continuously push the powder material to flow out through the discharge port, achieving the purpose of powder material transportation. The rotating plane formed by the rotating plate and the material pushing teeth has a large coverage area. During the rotation process, the material pushing teeth continuously push the powder material, enhancing the fluidity of the powder material, effectively avoiding the problems of powder material accumulation, caking and blockage, and ensuring the smooth flow and discharge of the material.

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0020] It should be noted that the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality" means two or more unless otherwise specifically defined.

[0021] As shown Figures 1-4 in the figure, there is a powder material storage tank, which is provided with a tank body 1. The tank body 1 is a cylindrical structure with an open upper part. An outlet 2 is arranged on the bottom plate of the tank body 1. A rotating plate 3 is horizontally arranged above the bottom plate of the tank body 1. The rotating plate 3 is connected to a rotating drive 4. The outer edge of the rotating plate 3 is evenly distributed with material pushing teeth 5. The material pushing teeth 5 are radially arranged with the center of the rotating plate 3 as the base point.

[0022] Specifically, the rotating plate 3 and the material pushing teeth 5 are located at the bottom of the tank body 1, and the rotating drive 4 can drive the rotating plate 3 and the material pushing teeth 5 to rotate. Since the material pushing teeth 5 are radially and evenly distributed with the center of the rotating plate 3 as the base point, the material pushing teeth 5 can cover a large area at the bottom of the tank body 1 when rotating. Or, the rotating plane formed by the rotation of the rotating plate 3 and the material pushing teeth 5 is the same as the inner diameter of the tank body 1. When the equipment is running, the rotating drive 4 drives the rotating plate 3 and the material pushing teeth 5 to rotate, continuously pushing the powder material at the bottom of the tank body 1 from the surrounding area to the position of the outlet 2. During this process, the powder material moves downward under the action of gravity, and the material pushing teeth 5 continuously push the powder material to flow out through the outlet, realizing the purpose of powder material transportation. In addition, by adjusting the rotation speed of the rotating drive 4, the rotation speed of the material pushing teeth 5 can be controlled, thereby adjusting the discharge amount, realizing the precise control of the discharge amount, and meeting different production requirements. In this application, the material pushing teeth 5 are radially and evenly distributed with the center of the rotating plate 3 as the base point, and the rotating plane formed by the rotating plate 3 and the material pushing teeth 5 has a large coverage area. During the rotation process, the material pushing teeth 5 continuously push the powder material, enhancing the fluidity of the powder material, effectively avoiding the problems of powder material accumulation, caking and blockage, ensuring the smooth flow and discharge of the material; by adjusting the rotation speed of the rotating drive 4, the precise control of the discharge amount can be realized, meeting the quantitative requirements in the production process.

[0023] As shown Figures 3-5 in the figure, a conical cap 6 is fixedly arranged on the rotating plate 3, and the inside of the conical cap 6 is a hollow structure.

[0024] Specifically, during the powder material transportation process, when the powder material in the tank body 1 accumulates too high, it will bring too much resistance to the rotating plate 3, resulting in the overload of the rotating drive 4 and unable to work normally. The conical cap 6 can limit the accumulation height of the powder material above the rotating plate 3, thereby reducing the burden on the rotating plate 3 and avoiding the occurrence of overload. In addition, by arranging the conical cap 6, the powder material can be prevented from entering the connection part between the rotating drive 4 and the rotating plate 3, thereby ensuring the normal operation of the equipment and extending the service life.

[0025] As shown Figure 5 in the figure, an outlet cap 7 is fixedly arranged inside the tank body 1. The outlet cap 7 is located above the outlet 2. There is a certain gap between the outlet cap 7 and the bottom plate of the tank body 1, and the material pushing teeth 5 can pass through the gap.

[0026] Specifically, by setting the discharge port cap 7, it is possible to prevent the powder from flowing out of the discharge port 2 during the stop operation of the tank body 1. A certain gap is maintained between the discharge port cap 7 and the bottom plate of the tank body 1 to allow the material pushing teeth 5 to pass through during rotation. When the rotary drive 4 drives the rotary plate 3 and the material pushing teeth 5 thereon to rotate, the material pushing teeth 5 continuously push the powder in the tank body 1 from the surrounding area towards the discharge port 2. Due to the gap between the discharge port cap 7 and the bottom plate of the tank body 1, the material pushing teeth 5 can smoothly pass through this gap and push the powder out of the discharge port 2, realizing the continuous conveying of the powder. The gap left between the discharge port cap 7 and the bottom plate of the tank body 1 is precisely calculated and designed. This gap can not only ensure that the material pushing teeth 5 can easily pass through but also prevent the material from leaking through the gap when it is stationary. The amount of material pushed out by the material pushing teeth 5 each time it rotates is certain, thus ensuring the uniformity of material discharge, reducing the fluctuation and accumulation of the material during the discharging process, enabling the subsequent equipment to receive and process the material at a more stable rate, contributing to improving the operating efficiency of the entire production line, and reducing the downtime and resource waste caused by uneven material flow.

[0027] As Figure 3 , 4 shown, a tank lining 8 is fixedly arranged on the inner wall of the tank body 1. The upper end of the tank lining 8 has a larger opening, and the lower end has a smaller opening.

[0028] Specifically, the tank lining 8 is a conical structure with a larger upper opening and a smaller lower opening. When the tank body 1 is filled with powder, the powder can naturally accumulate along the inclined surface of the lining, forming a relatively uniform pressure distribution, which can significantly reduce the direct pressure of the powder on the bottom of the tank body 1 and the rotary plate 3, thereby reducing the equipment wear and failure risk caused by overload. In addition, the conical tank lining helps to reduce the accumulation and caking of the material at the bottom and side walls of the tank body 1, making the material easier to be discharged, optimizing the fluidity of the powder in the tank body 1 and reducing the resistance.

[0029] In a powder storage tank of the present application, by setting the rotary plate 3 and the material pushing teeth 5, a larger rotation coverage area is formed. During the rotation process, the material pushing teeth 5 continuously push the powder, enhancing the fluidity of the powder, effectively avoiding the problems of powder accumulation, caking, and blockage, and ensuring the smooth flow and discharge of the material; by setting the conical cap 6, the accumulation height of the powder above the rotary plate 3 is restricted, thereby reducing the burden on the rotary plate 3 and avoiding the occurrence of overload.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection; it can also be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components.
