Description

Technical Field

[0001] This utility model relates to a stirring device, and more particularly to a stirring device for expanded graphite powder. Background Technology

[0002] Expanded graphite, a novel functional carbon material, is a loose, porous, worm-like substance obtained from natural graphite flakes through intercalation, washing, drying, and high-temperature expansion. Besides possessing the excellent properties of natural graphite, such as resistance to heat and cold, corrosion resistance, and self-lubrication, expanded graphite also exhibits properties not found in natural graphite, including softness, compression resilience, adsorption, environmental compatibility, biocompatibility, and radiation resistance. Expanded graphite was discovered as early as the 1860s by Brodie through heating natural graphite with chemical reagents such as sulfuric acid and nitric acid; however, its application only began a century later.

[0003] Patent publication number CN219682365U discloses an expandable graphite stirring device, including a stirring tank with a stirring chamber inside. A guide pipe is fixedly connected to the top of the inner wall of the stirring chamber, and a feeding box is fixedly connected to the top surface of one end of the guide pipe. A guide groove is provided on the top surface of the feeding box, and a discharge port is provided through the bottom surface of the inner wall of the guide pipe. A rotating shaft is rotatably connected inside the stirring chamber. While this patent achieves the mixing of expandable graphite and reagents through the cooperation of a stirring scraper and a guide pipe to produce expanded graphite, in situations requiring large-scale production of expanded graphite, this device increases output by increasing the amount of graphite raw material and reagents. However, excessive addition can cause graphite raw material to accumulate on the surface of the reagents, blocking the guide pipe and preventing other chemical substances mixed with the expanded graphite from being fully incorporated.

[0004] Therefore, it is necessary to design an expanded graphite powder stirring device to prevent the backflow of raw materials. Utility Model Content

[0005] In order to overcome the shortcomings of existing technologies that cannot prevent raw material backflow, thus affecting work efficiency, the technical problem to be solved is: to provide an expanded graphite powder stirring device that prevents raw material backflow.

[0006] The technical solution of this utility model is: an expanded graphite powder stirring device, including a fixed frame, a stirring cylinder, a stirring rack, a mounting frame, a first motor, a hopper, a second motor, and a feeding rod. The stirring cylinder is installed in the middle of the fixed frame, and the mounting frame is fixedly connected to the top of the stirring cylinder. The first motor is installed on the top of the mounting frame, and the output shaft of the first motor is connected to the stirring rack. The stirring rack extends into the interior of the stirring cylinder. Hoppers are fixedly connected to both sides of the mounting frame. The neck of the hopper is L-shaped. The second motor is installed on the side wall of the stirring cylinder, and the output shaft of the second motor is connected to the feeding rod. The feeding rod extends into the neck of the long end of the hopper.

[0007] Furthermore, an oxygen supply machine is installed on one side of the fixed frame, and the oxygen supply machine is connected to the inside of the neck of the hopper through a connecting pipe.

[0008] Furthermore, a conical shell is fixedly connected to the end of the mixing rack away from the first motor, and a material-pushing plate is fixedly connected to the outside of the conical shell.

[0009] Furthermore, electric slide rails are installed on both sides of the bottom of the mounting frame. The sliders of the two electric slide rails are fixedly connected to a connecting rod. The stirring frame is rotatably connected to the connecting rod, and the stirring frame is used to limit the connection rod.

[0010] Furthermore, the size of the feeding rod is adapted to the internal space of the hopper neck, and the second motor drives the feeding rod to rotate in one direction.

[0011] Furthermore, the portion of the stirring rack extending into the stirring cylinder has a radial tree-like structure, and the stirring rack is used to mix graphite raw materials with reagents.

[0012] The beneficial effects are: 1. This utility model effectively prevents graphite raw materials from being blocked and clumped during the feeding process by using the unidirectional rotation of the feeding rod and the continuous oxygen supply of the oxygen supply machine, ensuring that the raw materials enter the mixing drum smoothly and that the expanded graphite preparation and production work proceeds in an orderly manner.

[0013] 2. The stirring rack has a radial tree-shaped structure, which can effectively disperse the graphite raw materials floating on the surface of the reagents during rotation, ensuring that the graphite raw materials can be fully mixed with the reagents, improving reaction efficiency and reducing working time.

[0014] 3. Two hoppers are used for feeding graphite raw materials and liquid reagents respectively, achieving the effect of dry and wet separation. This prevents graphite raw materials and liquid reagents from mixing and adhering to the inner wall of the hopper neck when feeding at the same time, ensuring that the raw materials and reagents enter the mixing drum smoothly.

Detailed Implementation

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] Example: An expanded graphite powder stirring device, such as Figure 1 , Figure 2 and Figure 4 As shown, the system includes a fixed frame 1, a mixing drum 1001, a mixing rack 2, a mounting frame 3, a first motor 4, a feeding hopper 6, a second motor 7, and a feeding rod 8. The mixing drum 1001 is installed in the middle of the fixed frame 1. The mounting frame 3 is fixedly connected to the top of the mixing drum 1001. The first motor 4 is installed on the top of the mounting frame 3. The output shaft of the first motor 4 is connected to the mixing rack 2. The mixing rack 2 extends into the mixing drum 1001. The feeding hopper 6 is fixedly connected to both sides of the mounting frame 3. The neck of the feeding hopper 6 is L-shaped. The second motor 7 is installed on the side wall of the mixing drum 1001. The output shaft of the second motor 7 is connected to the feeding rod 8. The feeding rod 8 extends into the neck of the long end of the feeding hopper 6. Here, the two feeding hoppers are used for feeding graphite raw materials and liquid reagents, respectively, to achieve the effect of dry and wet separation. This prevents the graphite raw materials and liquid reagents from mixing and adhering to the inner wall of the neck of the feeding hopper 6 when feeding at the same time, and ensures that the raw materials and reagents enter the mixing drum smoothly.

[0024] like Figure 2 and Figure 6 As shown, a conical shell 11 is fixedly connected to the end of the stirring rack 2 away from the first motor 4. A material-pushing plate 12 is fixedly connected to the outside of the conical shell 11. Here, the inclined surface design of the conical shell 11 can prevent the accumulation of expanded graphite, and the design of the material-pushing plate can agitate the expanded graphite above the conical shell 11 and promote the flow of expanded graphite.

[0025] like Figure 3 As shown, electric slide rails 5 are installed on both sides of the bottom of the mounting frame 3. The sliders of the two electric slide rails 5 are fixedly connected to the connecting rod 51. The stirring frame 2 is rotatably connected to the connecting rod 51. The stirring frame 2 is used to limit the connecting rod 51. Here, the electric slide rail 5 drives the slider to slide up and down, and the slider drives the connecting rod 51 to slide up and down, thereby driving the stirring frame 2 to move up and down.

[0026] like Figure 1 , Figure 4 and Figure 5 As shown, an oxygen feeder 9 is installed on one side of the fixed frame 1. The oxygen feeder 9 is connected to the inside of the neck of the feeding hopper 6 through the connecting pipe 10. The size of the feeding rod 8 is adapted to the size of the internal space of the neck of the feeding hopper 6. The second motor 7 drives the feeding rod 8 to rotate in one direction. Here, the second motor 7 drives the output shaft to rotate counterclockwise. The output shaft drives the feeding rod 8 to rotate counterclockwise, so that the graphite raw material enters the mixing tank along the threaded groove. At the same time, the unidirectional rotation of the feeding rod 8 prevents the graphite raw material from clogging the neck when the feeding is too full.

[0027] like Figure 3 As shown, the part of the stirring rack 2 that extends into the stirring cylinder 1001 has a radial tree-like structure. Here, the radial tree-like structure of the stirring rack 2 can effectively disperse the graphite raw materials floating on the surface of the reagent, prevent the graphite raw materials from clumping, and ensure that the graphite raw materials and the reagents are in full contact.

[0028] This device can be used when preparing expanded graphite. First, sufficient reagent is poured into the mixing drum 1001 through one of the hoppers 6. Then, the first motor 4 is started, driving the output shaft to rotate. The output shaft drives the stirring frame 2 to rotate, stirring the different reagents and ensuring thorough mixing. By prioritizing the mixing of multiple reagents, the problem of insufficient contact between graphite raw materials and reagents in subsequent processes can be solved, improving work efficiency. Then, graphite raw materials are poured into the other hopper 6, and the second motor 7 is started. The second motor 7 drives the output shaft to rotate counterclockwise, driving the feed rod 8 to rotate counterclockwise. The graphite raw materials slide into the mixing drum 1001 through the threaded groove of the feed rod 8, mixing with the reagents. The unidirectional rotation of the feed rod 8 restricts the neck of the hopper 6, effectively preventing the graphite raw materials from clogging the neck when the hopper is overfilled. Simultaneously, the oxygen supply unit 9 delivers oxygen into the neck of the lower hopper 6 via the connecting pipe 10. This oxygen flow creates gaps between the graphite raw materials, effectively preventing clumping during feeding and improving work efficiency. After the graphite raw materials slide down, the radial tree-like structure of the stirring rack 2 disperses the graphite floating on the reagent surface during rotation, ensuring thorough mixing and improving the reaction efficiency, thus reducing working time. After the reaction, the electric slide rail 5 drives the slider upwards, which in turn drives the connecting rod 51 upwards, lifting the stirring rack 2. The expanded graphite flows out from the lower outlet, and the rotation of the stirring rack 2 further accelerates the flow rate and discharge of the expanded graphite.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
