Description

Technical Field

[0001] This utility model relates to the field of gypsum powder processing technology, and in particular to a gypsum powder aging and storage device. Background Technology

[0002] Gypsum powder, whose main component is calcium sulfate hemihydrate, is a widely used building material and industrial raw material. It is typically produced from natural gypsum ore or industrial byproducts through processes such as calcination and crushing. Gypsum powder possesses good plasticity, moderate strength after solidification, good fire resistance and sound insulation, and is easy to process.

[0003] Gypsum powder aging likely refers to storing gypsum powder under specific conditions for a period of time to improve its performance or stability. Gypsum is widely used in construction and industry, such as in the production of gypsum boards and molds. Desulfurized gypsum contains 10-15% attached water, which needs to be dried to 0.5% before entering a fluidized bed furnace to remove crystal water. Subsequently, the gypsum powder may absorb moisture during storage, leading to clumping. Clumped gypsum powder has poor flowability, is difficult to disperse evenly, and affects construction operations. The originally fine and uniform powder becomes inconsistent in particle size due to clumping, which affects the quality and consistency of the finished product.

[0004] Therefore, it is necessary to design a gypsum powder aging and storage device to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the above-mentioned shortcomings, the technical problem is to provide a gypsum powder aging and storage device.

[0006] The technical solution is as follows: A gypsum powder aging and storage device includes a support frame, a controller, an aging chamber, a feed pipe, a fixed shell, a motor, a rotating shaft, a transmission wheel, a belt, a distribution plate, a stirring plate, a return pipe, and an air pump. The controller is fixedly connected to one side of the lower part of the support frame, and the aging chamber is fixedly connected to the support frame. The feed pipe is connected to and communicates with the top of the aging chamber. The fixed shell is fixedly connected to one side of the interior of the aging chamber. The motor is fixedly connected to the front of the fixed shell, extending out of the aging chamber. The motor is electrically connected to the controller. The aging chamber is rotatably connected to a rotating shaft. Transmission wheels are fixedly connected to the output shaft of the motor and the rotating shaft. A belt is wound between the two transmission wheels. The distribution plate located below the feed pipe is fixedly connected to the top of the rotating shaft. A stirring plate is symmetrically fixedly connected to the lower part of the rotating shaft. The lower two sides of the aging chamber are connected to and communicate with return pipes that are also connected to and communicate with the feed pipe. The lower parts of the two return pipes are connected to and communicate with air pumps. The air pumps are electrically connected to the controller.

[0007] Furthermore, the lower structure of the aging chamber is funnel-shaped.

[0008] Furthermore, it also includes a screw feeder, with a screw feeder fixedly installed at the lower part of the support frame and connected to and communicating with the aging silo. The screw feeder is electrically connected to the controller.

[0009] Furthermore, it also includes a humidity monitoring rod and a sensor. The humidity monitoring rod is fixedly connected to the other side of the aging chamber, and the front of the humidity monitoring rod extends out of the aging chamber and is fixedly connected to a sensor. The sensor is electrically connected to the controller.

[0010] Furthermore, it also includes a sleeve, a heating tube, and a heat insulation cylinder. A sleeve is fixedly fitted in the middle of both return pipes. Multiple heating tubes are fixedly connected in a ring array on both sleeves. Each heating tube is electrically connected to the controller. A heat insulation cylinder corresponding to the multiple heating tubes is fixedly fitted on both sleeves.

[0011] Furthermore, both heat insulation cylinders are made of high-temperature resistant materials.

[0012] Furthermore, it also includes an ultrasonic generator and an ultrasonic transducer. The ultrasonic generator is fixedly connected to the lower part of the aging chamber, and the ultrasonic generator is electrically connected to the controller. The ultrasonic transducer is fixedly connected to the lower part of the aging chamber.

[0013] Beneficial effects: 1. This utility model starts the motor through the controller. The output shaft of the motor drives the transmission wheel to rotate. Under the transmission of the transmission wheel and belt, the rotating shaft rotates, and the material distribution plate and stirring plate also rotate, realizing the uniform distribution and full mixing of gypsum powder. This ensures that the gypsum powder is evenly sprinkled and reduces agglomeration. Then, the air pump generates airflow to form a reflux circulation, balances the moisture, avoids premature hydration reaction, improves the aging effect, and ensures the quality and stability of gypsum powder. It is suitable for high-efficiency production needs.

[0014] 2. This utility model uses a humidity monitoring rod to detect the moisture content of gypsum powder in the aging chamber in real time and transmits the data to the controller for analysis. The controller automatically adjusts the air pump recirculation and the ambient temperature and humidity based on the data to ensure the best aging effect of the gypsum powder, improve the automation level of the aging process, and guarantee the quality and stability of the gypsum powder, making it suitable for high-efficiency production needs.

[0015] 3. This utility model generates ultrasonic waves by starting an ultrasonic generator, which are converted into mechanical vibrations by a transducer and transmitted to the inner wall of the aging chamber, producing micro-vibrations. This prevents gypsum powder from adhering to the inner wall, maintains fluidity, improves the uniformity and flowability of the material, reduces material loss and cleaning difficulty, and is suitable for high-efficiency production needs.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: A gypsum powder aging and storage device, such as Figures 1-5As shown, the system includes a support frame 1, a controller 101, an aging chamber 2, a feed pipe 3, a fixed shell 4, a motor 5, a rotating shaft 6, a transmission wheel 7, a belt 8, a distribution plate 9, a stirring plate 10, a return pipe 11, an air pump 12, and a screw feeder 13. The controller 101 is screwed onto the lower left side of the support frame 1. The aging chamber 2, used for storing and aging gypsum powder, is screwed onto the upper part of the support frame 1. The lower part of the aging chamber 2 has a funnel-shaped structure to accelerate the flow rate of gypsum powder within the chamber. The top of the aging chamber 2 is connected to and communicates with the feed pipe 3. Gypsum powder is fed into the aging chamber 2 through the feed pipe 3 for aging and storage. A fixed shell 4 is welded to the upper side of the aging chamber 2. A motor 5 is installed on the top of the front of the fixed shell 4, extending through the top of one side of the aging chamber 2, via screws. The motor 5 is electrically connected to the controller 101. Rotating shafts 6 are rotatably connected inside the aging chamber 2. Drive wheels 7 are welded to the output shaft of the motor 5 and the upper part of the rotating shaft 6. A belt 8 is wound between the two drive wheels 7. The controller 101 starts the motor 5, and the output shaft of the motor 5 drives one of the drive wheels 7. Under the transmission of the belt 8, the other drive wheel 7 drives the rotating shaft 6 to rotate. A distribution plate 9 is welded to the top of the rotating shaft 6, located directly below the feed pipe 3. The upper diameter of the distribution plate 9 is smaller than its lower diameter. Shaft 6 can drive the distribution plate 9 to rotate, so the gypsum powder input from the feed pipe 3 falls directly into the distribution plate 9. Under the action of the distribution plate 9, the input gypsum powder is evenly sprinkled inside the aging chamber 2. The lower part of the rotating shaft 6 is symmetrically welded with spiral-shaped stirring plates 10. The rotating shaft 6 will drive the stirring plates 10 to rotate, stirring the gypsum powder inside the aging chamber 2, reducing agglomeration, improving powder flowability, and promoting uniform moisture distribution. The lower left and right sides of the aging chamber 2 are connected to and connected to the feed pipe 3, and the lower part of the two return pipes 11 are connected to and connected to the air pump 12. The air pump 12 is connected to the controller 101. Electrically connected, the air pump 12 is started by the controller 101, generating airflow to draw the gypsum powder in the lower part of the aging chamber 2 into the return pipe 11 and then into the feed pipe 3, and then into the aging chamber 2 through the feed pipe 3, forming a return circulation to balance the free moisture and avoid premature hydration reaction. The lower part of the support frame 1 is equipped with a screw feeder 13 connected to and communicating with the aging chamber 2. The screw feeder 13 is electrically connected to the controller 101. The screw feeder 13 is started by the controller 101 to transport the gypsum powder in the aging chamber 2 to the next process. When the transport is not needed, the screw feeder 13 can be turned off by the controller 101.

[0024] like Figure 4As shown, it also includes a humidity monitoring rod 14 and a sensor 15. The humidity monitoring rod 14 is installed on the lower side of the aging chamber 2 by screws. The front side of the humidity monitoring rod 14 protrudes from the aging chamber 2 and is installed with a sensor 15 by screws. The sensor 15 is electrically connected to the controller 101. The humidity monitoring rod 14 can detect the moisture content of the gypsum powder in the aging chamber 2. The sensor 15 transmits the collected data to the controller 101. After receiving and analyzing the data, the controller 101 can automatically adjust the parameters in the aging process according to actual needs, such as starting the air pump 12 for reflux circulation, adjusting the ambient temperature and humidity, etc., to ensure the best aging effect of the gypsum powder.

[0025] like Figure 1 and Figure 5 As shown, it also includes a sleeve 16, a heating tube 17, and a heat insulation cylinder 18. The sleeve 16 is installed in the middle of each of the two return pipes 11 by screws. Multiple heating tubes 17 are installed in a ring array on the outer side of each of the two sleeves 16 by screws. Each heating tube 17 is electrically connected to the controller 101. Heat insulation cylinders 18 are welded onto each of the two sleeves 16 to cover the corresponding multiple heating tubes 17. Both heat insulation cylinders 18 are made of high temperature resistant material. If the moisture content of the gypsum powder exceeds the standard, the heating tube 17 can be activated by the controller 101 to heat up the return pipe 11. During the reflux process of the gypsum powder in the return pipe 11, the gypsum powder is heated, thereby achieving forced drying and aging.

[0026] like Figure 1 and Figure 5 As shown, it also includes an ultrasonic generator 19 and an ultrasonic transducer 20. The ultrasonic generator 19 is installed on the lower front side of the aging chamber 2 by screws. The ultrasonic generator 19 is electrically connected to the controller 101. The ultrasonic transducer 20 is installed on the lower outer side of the aging chamber 2 by screws. The ultrasonic generator 19 is activated by the controller 101 to generate ultrasonic waves. The ultrasonic waves are converted into mechanical vibrations by the ultrasonic transducer 20. These vibrations are transmitted to the inner wall of the aging chamber 2 to prevent gypsum powder from adhering to the inner wall.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
