Description

Technical Field

[0001] This utility model relates to the field of powder storage technology, and in particular to a powder storage device for preventing agglomeration. Background Technology

[0002] Powdered substances are widely used in many industries such as chemical, food, pharmaceutical, and building materials. For example, in the chemical industry, powdered raw materials such as sodium carbonate and calcium carbonate are the basis for the production of many chemical products. In the food industry, powdered foods such as milk powder, coffee powder, and seasonings are very popular among consumers. In the pharmaceutical industry, drug powders are the key to the preparation of various dosage forms of drugs.

[0003] However, these powders are prone to clumping during storage due to changes in environmental humidity and temperature, as well as the inherent properties of the powders themselves. Currently, traditional powder storage methods mostly use ordinary storage containers, such as plastic buckets and metal cans. While these containers can protect the powder to some extent, they lack effective anti-caking measures. Traditional powder storage devices have simple structures and lack effective stirring methods and moisture-proof functions, making it difficult to fundamentally solve the powder clumping problem. When external moisture enters the storage container, the powder inside the container easily becomes damp and clumps over time. Clumped powder not only has poor flowability, causing great inconvenience to subsequent transportation, metering, and use, but may also affect product quality.

[0004] Existing powder storage equipment has many shortcomings in preventing agglomeration. There is a need for a new type of storage equipment that can effectively prevent agglomeration and meet the specific needs of the industry. In summary, developing an anti-agglomeration powder storage equipment has important practical significance and market demand. Utility Model Content

[0005] To overcome the aforementioned drawbacks, this invention provides a powder storage device that prevents caking.

[0006] Technical Solution: A powder storage device for preventing agglomeration includes a heat storage frame, a storage tank, a top plate, a fixing frame, a sealing cover, a feed pipe, a sleeve, a fixing block, a motor, a stirring shaft, a stirring column, a scraper, a propeller blade, and a controller. The storage tank is located inside the heat storage frame, and the top plate is fixedly connected to the top of the storage tank. The fixing frame is fixedly connected to the outer wall of the heat storage frame, and the sealing cover is fixedly connected to the top of the heat storage frame. The feed pipe is fixedly connected to the top of the sealing cover, extending downwards into the storage tank and engaging with the top plate. A sleeve is fitted over the feed pipe protruding from the top of the sealing cover. A fixing block is fixedly connected to the middle of the top of the top plate, and a motor is fixedly connected inside the fixing block. The output shaft of the motor is fixedly connected to the stirring shaft, and a stirring column and a scraper are fixedly connected to the middle of the stirring shaft. The stirring column is located inside the scraper, and several stirring columns are fixedly connected to the inner side of the scraper. The outer wall of the scraper is tightly fitted to the inner wall of the storage tank. A propeller blade is fixedly connected to the bottom of the stirring shaft. A controller is fixedly connected to the outer wall of the heat storage frame, and the motor is electrically connected to the controller.

[0007] In addition, it is particularly preferred that the device also includes a placement cylinder, a pneumatic compressor and a nozzle. The placement cylinder is slidably placed on the top of the top plate and is located inside the storage tank. The placement cylinder has multiple through holes. The pneumatic compressor is fixedly connected to the top of the top plate. The pneumatic compressor extends downward into the storage tank and is fixedly connected to the nozzle at its output end. The pneumatic compressor is electrically connected to the controller.

[0008] In addition, it is particularly preferred that the device also includes heating tubes. Two sets of heating tubes are arranged in the annular interlayer between the heat storage frame and the storage tank, with two heating tubes in each set. Each heating tube is fixedly connected to the outer wall of the storage tank, and all four heating tubes are electrically connected to the controller.

[0009] In addition, it is particularly preferred that the device also includes a glass plate, and that the heat storage frame and the outer wall of the storage tank have observation openings, both of which are fitted with glass plates.

[0010] In addition, it is particularly preferred that a one-way valve is included, with the discharge port of the storage tank being fixedly connected to the one-way valve.

[0011] In addition, it is particularly preferred that the bracket also includes support columns, with support columns fixedly connected to the lower part of the bracket, and anti-slip pads provided at the bottom of several support columns.

[0012] The beneficial effects are: 1. This utility model uses a motor to drive the stirring shaft, stirring column, scraper, and propeller blade to rotate together, which stirs the powder in the storage tank in all directions. The stirring column continuously rolls in the powder, disrupting the aggregation state of the powder particles. The scraper closely adheres to the inner wall of the storage tank, which can scrape off the powder adhering to the inner wall in time, preventing the powder from clumping due to prolonged residence. When the propeller blade rotates, it turns the powder at the bottom upward, allowing the powder in the entire storage tank to be fully mixed and form a circulating flow. Through continuous stirring, the powder can be effectively kept in a loose state, greatly reducing the probability of clumping and ensuring stable powder quality.

[0013] 2. This utility model, through the setting of the placement cylinder, which has multiple through holes, greatly increases the contact area between the drying pack and the air inside the can, enabling the drying pack to absorb moisture from the storage can more quickly and fully. For some humidity-sensitive powders, it can control the humidity inside the can at a low level, ensuring that the performance of the powder is not affected.

[0014] 3. This utility model utilizes a pneumatic compressor in its equipment. The pneumatic compressor injects compressed gas into the storage tank through a nozzle. The impact force generated by the compressed gas acts on the powder, allowing the powder to flow smoothly and preventing it from accumulating and clogging at the outlet. For some powders with poor flowability, such as pigment powder, clumps are easily formed at the outlet, leading to poor discharge. The pneumatic-assisted discharge function of this equipment can effectively solve this problem and ensure a smooth discharge process. Attached Figure Description

[0020] Example: A powder storage device to prevent clumping, such as Figures 1-4 As shown, the system includes a heat storage frame 1, a storage tank 2, a top plate 3, a fixing frame 4, a sealing cover 5, a feed pipe 6, a sleeve 7, a fixing block 8, a motor 9, a stirring shaft 10, a stirring column 11, a scraper 12, a propeller blade 13, and a controller 20. The heat storage frame 1 houses the storage tank 2, which has a cylindrical upper part and a conical lower part. The heat storage frame 1 has the same shape as the storage tank 2. The top plate 3 is bolted to the top of the storage tank 2. A fixing frame 4 is welded to the lower middle part of the outer wall of the heat storage frame 1. The sealing cover 5 is bolted to the top of the heat storage frame 1. A feed pipe 6 is welded to the top of the sealing cover 5, extending downwards to the storage tank. Inside the tank 2 and snapped into the top plate 3, a sleeve 7 is fitted over the feed pipe 6 protruding from the top of the sealing cover 5. A fixing block 8 is connected to the top center of the top plate 3 by bolts. A motor 9 is installed inside the fixing block 8 by screws. A stirring shaft 10 is welded to the output shaft of the motor 9. A scraper 12 is welded to the middle of the stirring shaft 10. A stirring column 11 is located inside the scraper 12. Four stirring columns 11 are welded to the inside of the scraper 12. The outer wall of the scraper 12 is tightly fitted to the inner wall of the storage tank 2. A propeller blade 13 is welded to the bottom of the stirring shaft 10. A controller 20 is installed on the upper right side of the outer wall of the heat storage frame 1 by screws. The motor 9 is electrically connected to the controller 20.

[0021] When this device is needed for storage and mixing, the operator first removes the sleeve 7 upwards and pours the powder into the storage tank 2 through the feed pipe 6. Then, the sleeve 7 is put back in its original position. After that, the motor 9 is started by the controller 20. The output shaft of the motor 9 drives the stirring shaft 10 to rotate, which in turn drives the stirring column 11, scraper 12 and propeller blade 13 to rotate together. This stirs the powder in the storage tank 2 to prevent the powder from clumping. The scraper 12 can scrape off the powder adhering to the inner wall of the storage tank 2. When the propeller blade 13 rotates, it can turn the powder at the bottom upwards, further enhancing the stirring effect. If stirring is not needed, the motor 9 can be turned off by the controller 20.

[0022] like Figure 2 and Figure 3 As shown, it also includes a placement cylinder 14, a pneumatic compressor 15, and a nozzle 16. The placement cylinder 14 is slidably placed on the front side of the top of the top plate 3, and is located inside the storage tank 2. The placement cylinder 14 has multiple through holes. The pneumatic compressor 15 is installed on the top left side of the top plate 3 by screws. The pneumatic compressor 15 extends downward into the storage tank 2, and the nozzle 16 is welded to its output end. The pneumatic compressor 15 is electrically connected to the controller 20. Figure 1 and Figure 2 As shown, it also includes a one-way valve 19, and the discharge port of the conical bottom of the storage tank 2 is welded with a one-way valve 19.

[0023] When dehumidification is required inside storage tank 2, first open the sealing cover 5 and place the drying pack into the placement cylinder 14. Since the placement cylinder 14 has multiple through holes, the drying pack can better absorb the moisture inside storage tank 2. When discharging, first place the container on the fixed frame 4, and then open the one-way valve 19 to let the powder flow into the container. During the discharge process, start the air compressor 15 through the controller 20. The air compressor 15 sprays compressed gas into storage tank 2 through the nozzle 16. At this time, the compressed gas will have a certain impact force on the powder, so that the powder will not block the discharge port and can be discharged better. When the discharge is completed, first turn off the air compressor 15 through the controller 20, and then close the one-way valve 19.

[0024] like Figure 4 As shown, it also includes heating tubes 17. Two sets of heating tubes 17 are arranged vertically in the annular interlayer between the heat storage frame 1 and the storage tank 2. Each set has two heating tubes 17. All four heating tubes 17 are fixedly connected to the outer wall of the storage tank 2 and are electrically connected to the controller 20.

[0025] When internal heating is required, the heating tube 17 is first activated by the controller 20. The heating tube 17 heats the inside of the storage tank 2. The heating tube 17 continues to work and, with the heat storage effect of the heat storage frame 1, can better heat or maintain the temperature inside the storage tank 2 and keep the inside of the storage tank 2 dry. If heating is not required, the heating tube 17 can be turned off by the controller 20.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, it also includes a glass plate 18. The front side walls of the heat storage frame 1 and the storage tank 2 are provided with rectangular observation ports, and the glass plate 18 is embedded in both observation ports.

[0027] When it is necessary to observe the internal powder condition, staff can observe the interior through glass plate 18.

[0028] like Figure 1 As shown, it also includes support columns 21. Support columns 21 are welded to the lower part of the fixing frame 4, and the bottom of the four support columns 21 are provided with anti-slip pads.

[0029] If this device is to be used in slippery areas, the anti-slip pads at the bottom of the support column 21 will provide better anti-slip protection for the fixing frame 4 under the first layer of anti-slip effect of the support column 21.
