[0015] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0017] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0018] In the embodiment, Figure 1-3A calcium carbonate powder separation device is provided, comprising a shell 1 with an opening on one side, a hopper 2 for conveying calcium carbonate raw material is provided on the top of the shell 1, a screen 3 located at the opening is provided on the inner side of the shell 1, and the screen 3 is located at the discharge end of the upper hopper 2, a control component 4 for driving the screen to vibrate continuously is provided on the shell 1, a screw conveying device 5 is provided at the end of the screen 3 away from the upper hopper 2, and a heating component 6 is provided at the discharge end of the screw conveying device 5, which is used to evaporate the residual aqueous solution in the calcium carbonate raw material, and the calcium carbonate raw material is conveyed into the shell 1 through the upper hopper 2. The design of the upper hopper 2 facilitates the continuous and stable supply of raw materials, ensuring the continuity of the production process. After the raw materials enter the shell 1, they fall on the screen 3, and the mesh size of the screen 3 is small, allowing only aqueous solutions to pass through. Therefore, the calcium carbonate raw materials can be preliminarily screened and most of the aqueous solutions can be separated. Driven by the control component 4, the screen 3 is continuously vibrated, and the vibration can cause the raw materials to continuously roll and jump on the screen 3, thereby achieving effective separation. The calcium carbonate raw materials that have been preliminarily separated are captured and conveyed by the screw conveyor 5. The screw conveyor 5 rotates to propel the calcium carbonate powder forward along its axial direction, thereby achieving continuous collection and transportation to the heating component 6. The heating component 6 evaporates the aqueous solution that may remain in the calcium carbonate powder, further improving the purity and quality of the calcium carbonate powder, and ensuring the stability and performance of the final product.

[0019] Reference Figure 1-3 , wherein the control assembly 4 includes an optical axis 41, one side surface of the screen 3 is rotatably connected to the optical axis 41 with one end penetrating and extending to the other side surface, both ends of the optical axis 41 are provided with a U-shaped clamp 42 fixedly mounted on the housing 1, one side surface of the screen 3 is fixedly mounted with a vibration motor 43, and an elastic connector 44 is provided between the other side surface and the housing 1;

[0020] Through the above-mentioned structural arrangement, the U-shaped clamp 42 provides a certain degree of freedom for the optical axis 41, ensuring the stability and reliability of the vibration of the screen 3. The vibration motor 43 is fixedly mounted on one side surface of the screen 3 and is the power source for driving the screen 3 to vibrate. When the vibration motor 43 is started, it will generate high-frequency vibrations, which are transmitted to the screen 3, causing the calcium carbonate raw material on the screen 3 to be subjected to periodic impact force, thereby realizing the separation of the aqueous solution.

[0021] Reference Figure 1-3 , wherein the elastic connecting member 44 includes a telescopic rod, the fixed end of the telescopic rod is hinged to the housing 1, and the telescopic end thereof is hinged to the screen 3, and a spring located outside the telescopic rod is provided between the housing 1 and the screen 3;

[0022] Through the above-mentioned structural setting, when the screen 3 is subjected to vibration, the telescopic rod will be telescoped and adjusted according to the direction and amplitude of the vibration. This adjustment effect enables the screen 3 to maintain a certain vibration frequency while avoiding direct collision with the shell 1 or generating excessive impact force. When the screen 3 is subjected to vibration impact, the spring will deform and absorb part of the vibration energy.

[0023] Reference Figure 1-3 The screw conveying device 5 includes a hollow tube 51 fixedly mounted on the housing 1, and a feed hole 52 for the calcium carbonate raw material to pass through is opened on the hollow tube 51. A driving motor 53 is fixedly mounted on the housing 1. The output end of the driving motor 53 is fixedly connected to a rotating shaft 54 ​​having one end passing through and extending from the housing 1. The rotating shaft 54 ​​is located inside the hollow tube 51, and a spiral blade 55 is welded on the rotating shaft 54.

[0024] Through the above-mentioned structural arrangement, when the drive motor 53 is started, its output end drives the rotating shaft 54 ​​to start rotating and the spiral blades 55 to rotate. The thrust of the spiral blades on the calcium carbonate powder and the friction between the calcium carbonate powders are utilized to achieve continuous and stable transportation of the calcium carbonate raw material.

[0025] Reference Figure 1-3 The heating assembly 6 includes a frame 61 fixedly mounted on the housing 1, and the frame 61 is connected to the hollow tube 51 via a delivery pipe. A plurality of stirring rods 62 are welded to the rotating shaft 54 ​​and are equidistantly distributed in an annular shape and all located in the frame 61. The frame 61 is provided with a plurality of heating wires 63 equidistantly arranged along the rotating shaft 54. The bottom of the frame 61 is connected to a discharge pipe 64, and an electric butterfly valve 65 is provided in the discharge pipe 64.

[0026] Through the above-mentioned structural arrangement, the calcium carbonate powder enters the frame 61 through the hollow tube 51, and then the multiple heating wires 63 start working to generate heat to heat the calcium carbonate powder. At the same time, the stirring rod 62 continuously stirs the calcium carbonate powder as the rotating shaft 54 ​​rotates. Under the stirring action of the stirring rod 62, the calcium carbonate powder is fully mixed in the frame 61 while maintaining a fluid state, which is conducive to uniform heat transfer and uniform heating of the calcium carbonate powder. When the calcium carbonate powder reaches the required heating temperature or processing time, the electric butterfly valve 65 is controlled to open, and the calcium carbonate powder is discharged from the discharge pipe 64 and enters the next process.
