Description

Technical Field

[0001] This utility model relates to the field of drying technology for water-soluble inorganic salt carriers, and in particular to a vacuum drying device for water-soluble inorganic salt carriers. Background Technology

[0002] Water-soluble inorganic salt carriers refer to substances composed of inorganic compounds that can dissolve in water. They are used as supports or transport media for certain substances (such as catalysts, drugs, nutrients, etc.). Common examples include sodium chloride, sodium sulfate, and phosphates. Water-soluble inorganic salt carriers can disperse active ingredients (such as catalysts) on the carrier, increase the specific surface area of ​​the active ingredients, improve reaction efficiency, and provide physical support for some tiny active ingredients, preventing aggregation and maintaining their activity.

[0003] In existing technologies, when it is necessary to dry water-soluble inorganic salt carriers to remove moisture, they are generally placed in a drying drum inside a drying chamber. The air inside is then extracted by a vacuum pump. The vacuum environment also helps to remove moisture from the material and shorten the drying time. Then, the heating tube assembly is activated to dry it. However, the lack of a stirring device inside the drying drum results in some materials not being completely dried, which reduces the quality of vacuum drying of water-soluble inorganic salt carriers. Utility Model Content

[0004] The purpose of this invention is to solve the problem that some materials in the drying barrel are not completely dried due to the lack of a stirring device in the drying barrel when using existing equipment, and to propose a vacuum drying device for water-soluble inorganic salt carriers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vacuum drying device for water-soluble inorganic salt carriers, comprising a drying chamber and a drying barrel, wherein a vacuum pump is in contact with the back of the drying chamber, a connecting pipe is fixedly installed on the top of the vacuum pump, and the output end of the connecting pipe is connected to the interior of the drying chamber, a fixing frame is fixedly installed on the top of the fixing frame, a drive motor is fixedly installed on the top of the drive motor, a drive rod is fixedly installed on the bottom of the drive motor, a plurality of stirring blades are fixedly installed on the outer wall of the drive rod, and two strip grooves are formed at the bottom of the inner wall of the drying chamber.

[0006] Preferably, the inner surface of both strip grooves is movably fitted with strip sliders.

[0007] Preferably, a connecting plate is fixedly installed between the tops of the two strip sliders, and the top of the connecting plate is fixedly connected to the bottom of the drying barrel.

[0008] Preferably, a handle is fixedly installed on one side of the outer wall of the connecting plate, and two heating tube assemblies are fixedly installed on the inner surface of the drying oven.

[0009] Preferably, a temperature sensor is fixedly installed on one side of the inner wall of the drying oven, and a pressure sensor is fixedly installed on one side of the inner wall of the drying oven.

[0010] Preferably, a pressure relief pipe is fixedly inserted into one side of the outer wall of the drying oven, and a pressure relief valve is fixedly installed on the outer wall of the pressure relief pipe.

[0011] Preferably, a controller is fixedly installed on one side of the outer wall of the drying oven, and the outer wall of the controller is electrically connected to the outer wall of the drive motor.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, the air inside the drying chamber is extracted by a vacuum pump and connecting pipe. Then, the controller starts two heating tube assemblies, which, with the help of a temperature sensor, heat the interior to the required temperature. Next, the controller starts the drive motor, which drives the drive rod and multiple stirring blades to stir the material, ensuring uniform heating of the material inside the drying chamber and diffusion of moisture, so that the material is fully dried and the vacuum drying effect of water-soluble inorganic salt carrier is improved.

[0014] In this invention, the handle, two strip grooves, two strip sliders, and connecting plate facilitate the placement of the drying barrel in the designated position inside the drying chamber and make it easy to remove. Furthermore, through the action of the pressure sensor, when the internal pressure rises to a preset threshold due to water evaporation, the controller opens the pressure relief valve and discharges some water vapor through the pressure relief pipe to maintain the pressure inside the drying chamber within a suitable range, thereby improving the effectiveness of the vacuum drying device for water-soluble inorganic salt carriers.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-4 As shown, this utility model provides a vacuum drying device for water-soluble inorganic salt carriers, including a drying chamber 1 and a drying barrel 2. A vacuum pump 3 is in contact with the back of the drying chamber 1. A connecting pipe 4 is fixedly installed on the top of the vacuum pump 3, and the output end of the connecting pipe 4 is connected to the interior of the drying chamber 1. A fixing frame 5 is fixedly installed on the top of the drying barrel 2. A drive motor 6 is fixedly installed on the top of the fixing frame 5. A drive rod 7 is fixedly installed on the bottom of the drive motor 6. Multiple stirring blades 8 are fixedly installed on the outer wall of the drive rod 7.

[0024] The overall effect of Embodiment 1 is as follows: the water-soluble inorganic salt carrier to be dried is placed in the drying barrel 2 and placed in the drying chamber 1. The chamber door is closed, and the vacuum pump 3 is started by the controller 18 to extract the air in the drying chamber 1 along the connecting pipe 4, so that the inside of the drying chamber 1 is in a vacuum state. Then, the heating tube assembly 13 installed on both sides of the inner wall of the drying chamber 1 is started by the controller 18. Under the action of the temperature sensor 14, the internal temperature is raised to the required temperature range, and the required temperature can dry and heat the material in the drying barrel 2. Then, the drive motor 6 installed on the fixed frame 5 is started by the controller 18. The drive motor 6 can work normally under the internal heating temperature, so that it drives the drive rod 7 and multiple stirring blades 8 to stir the water-soluble inorganic salt carrier in the drying barrel 2, thereby ensuring the uniformity of heating of the internal material and the diffusion of moisture, so that the material is fully dried and the vacuum drying effect of the water-soluble inorganic salt carrier is improved.

[0025] Example 2: Figures 2-4 As shown, two strip grooves 9 are opened at the bottom of the inner wall of the drying chamber 1. Strip sliders 10 are movably embedded in the inner surface of the two strip grooves 9. A connecting plate 11 is fixedly installed between the tops of the two strip sliders 10. The top of the connecting plate 11 is fixedly connected to the bottom of the drying chamber 2. A handle 12 is fixedly installed on one side of the outer wall of the connecting plate 11. Two heating tube assemblies 13 are fixedly installed on the inner surface of the drying chamber 1. A temperature sensor 14 is fixedly installed on one side of the inner wall of the drying chamber 1. A pressure sensor 15 is fixedly installed on one side of the inner wall of the drying chamber 1. A pressure relief pipe 16 is fixedly inserted into one side of the outer wall of the drying chamber 1. A pressure relief valve 17 is fixedly installed on the outer wall of the pressure relief pipe 16. A controller 18 is fixedly installed on one side of the outer wall of the drying chamber 1, and the outer wall of the controller 18 is electrically connected to the outer wall of the drive motor 6.

[0026] The overall effect of Embodiment 2 is as follows: Since a connecting plate 11 is installed at the bottom of the drying barrel 2, and two strip-shaped sliders 10 installed at the bottom of the connecting plate 11 are movably embedded in two strip-shaped grooves 9 opened at the bottom of the inner wall of the drying chamber 1, the connecting plate 11 and the drying barrel 2 can only be removed by using the handle 12 and external force. Thus, the drying barrel 2 can be placed in the designated position in the drying chamber 1 each time, and it is also easy to remove it with the help of tools, preventing the heated drying barrel 2 from burning the staff. Secondly, through the function of the pressure sensor 15 installed on one side of the inner wall of the drying chamber 1, when the pressure in the drying chamber 1 rises to the preset threshold due to the evaporation of moisture in the material, the controller 18 opens the pressure relief valve 17 installed on the pressure relief pipe 16, and discharges some of the water vapor in the drying chamber 1 through the pressure relief pipe 16 to maintain the pressure in the drying chamber 1 within a suitable range, thereby improving the use effect of the vacuum drying device for water-soluble inorganic salt carrier.

[0027] Working principle: First, the water-soluble inorganic salt carrier material to be dried is placed in the drying drum 2. Since a connecting plate 11 is installed at the bottom of the drying drum 2, and two strip-shaped sliders 10 installed at the bottom of the connecting plate 11 are movably embedded in two strip grooves 9, the connecting plate 11 and the drying drum 2 can be moved into the designated position inside the drying chamber 1 with the help of tools and handle 12. The chamber door is closed, and the vacuum pump 3 is started via controller 18, causing the air inside the drying chamber 1 to be discharged along the connecting pipe 4 and creating a vacuum. Then, the two heating tube assemblies 13 are started via controller 18. Under the action of the temperature sensor 14, the internal temperature can be raised to the required temperature range. Finally, the heating tubes installed on the drying chamber 13 are started via controller 18. The drive motor 6 on the fixed frame 5 drives the drive rod 7 and multiple stirring blades 8 to stir the water-soluble inorganic salt carrier in the drying tank 2, thereby ensuring the uniformity of heating of the internal material and the diffusion of moisture, so that the material is fully dried. At the same time, under the action of the pressure sensor 15, when the internal pressure rises to a preset threshold due to the evaporation of moisture in the material, the controller 18 opens the pressure relief valve 17, allowing some of the water vapor in the drying chamber 1 to be discharged along the pressure relief pipe 16, thereby maintaining the pressure in the drying chamber 1 within a suitable range. In general, the vacuum drying effect of the water-soluble inorganic salt carrier is improved, thereby improving the performance of the vacuum drying device for the water-soluble inorganic salt carrier.
