Description

Technical Field

[0001] This utility model relates to the field of expanded graphite, and in particular to a continuous cleaning device for expanded graphite. Background Technology

[0002] Graphene, a two-dimensional material composed of sp² hybridized carbon atoms, exhibits outstanding mechanical and electrical properties. Currently, the redox method is the mainstream technology for the large-scale preparation of graphene. This process involves using chemical solutions such as sulfuric acid and nitric acid, as well as oxidants such as potassium permanganate and hydrogen peroxide, to oxidize natural graphite, expand its interlayer spacing, and insert oxides, thereby forming graphite oxide. Subsequently, the reactants are removed by washing with water, and the washed solid is subjected to low-temperature drying to finally obtain graphite oxide powder. This series of preparation processes cannot be separated from the assistance of efficient cleaning equipment.

[0003] However, most of the existing expanded graphite cleaning equipment on the market uses the method of placing the container containing the graphite to be cleaned directly into the water tank, which requires changing the water in the tank multiple times to complete the cleaning, increasing the complexity of the operation.

[0004] To address the aforementioned technical problems, existing technology has proposed a continuous cleaning device for expanded graphite, such as Chinese Patent Application No. CN202323051229.1. This utility model belongs to the technical field of graphite cleaning equipment, and particularly to a continuous cleaning device for expanded graphite. It includes a base frame and a cleaning box. The cleaning box is fixedly installed on the upper end of the base frame. A first cleaning groove and a second cleaning groove are respectively formed on the upper surface of the cleaning box. A fixing frame plate is fixedly installed on the side of the cleaning box. A sliding groove is formed on the surface of the fixing frame plate. An L-shaped connecting plate is slidably connected to the inner wall of the sliding groove. A holding basket is fixedly installed at the end of the L-shaped connecting plate. A wastewater treatment mechanism is connected to the end of the cleaning box. This utility model, by dividing the cleaning box into two cleaning grooves and then combining them with the fixing frame plate, sliding groove, and L-shaped connecting plate, allows the holding basket to be transferred to the other cleaning groove immediately after cleaning in one cleaning groove, thereby achieving a better continuous cleaning effect and improving cleaning cleanliness and efficiency.

[0005] However, the existing technologies mentioned above have the following shortcomings: 1. The cleaning box still needs to be manually transferred, which increases labor costs and reduces production efficiency; 2. When the cleaning box is placed in the cleaning tank, the cleaning box is merely in a static state, and the cleaning effect is limited. Summary of the Invention

[0006] To address the aforementioned technical problems, this utility model proposes a continuous cleaning device for expanded graphite, which solves the issues of the cleaning box needing to be manually moved and the limited cleaning effect when the cleaning box is merely in a static state.

[0007] An expanded graphite continuous cleaning device includes a pair of horizontally placed cleaning tanks and a cleaning box placed in one of the cleaning tanks. A transfer part is provided between the pair of cleaning tanks, which can transfer the cleaning box to the cleaning tank on the other side. A water changing mechanism is provided on one side of each cleaning tank, which can replace the water in the cleaning tank.

[0008] The transfer unit includes a machine platform horizontally arranged between a pair of cleaning tanks, a rotating lifting cylinder vertically arranged on the machine platform, and a rotating lifting mechanism inside the machine platform. The rotating lifting mechanism causes the rotating lifting cylinder to rotate and lift on the same axis. An installation rod is installed on one side of the top of the rotating lifting cylinder. One side of the installation rod is detachably connected to one side of the cleaning box. After the rotating lifting cylinder is raised, it can rotate so that the installation rod can transfer the cleaning box from one side of the cleaning tank to the other side of the cleaning tank.

[0009] The end of the mounting rod connected to the cleaning box is equipped with a telescopic device, which enables the cleaning box to move vertically up and down in the cleaning tank.

[0010] Furthermore, the rotary lifting mechanism includes a lifting column disposed inside the machine base and a rotary drive device disposed on one side inside the machine base. A rotary shaft seat is coaxially disposed at the top of the lifting column, and the bottom of the rotary lifting cylinder is coaxially movably disposed in the rotary shaft seat. The rotary drive device enables the rotary lifting cylinder to rotate in the rotary shaft seat about the axis of the rotary lifting cylinder.

[0011] Furthermore, the outer wall of the rotating lifting cylinder is provided with teeth, and the teeth are a number of strip-shaped protrusions uniformly and vertically arranged on the outer wall of the rotating lifting cylinder. The rotating drive device includes a drive motor and a drive gear coaxially sleeved on the output shaft of the drive motor. A transmission gear meshes with one side of the drive gear. The transmission gear meshes with the number of strip-shaped protrusions provided on the outer wall of the rotating lifting cylinder. The rotation surfaces of the drive gear, the transmission gear, and the rotating lifting cylinder are coplanar. After the rotating drive gear rotates, it drives the rotating lifting cylinder to rotate through the transmission gear. After the rotating lifting cylinder rises and falls, it still meshes with the transmission gear.

[0012] Furthermore, a horizontal mounting platform is provided on one side of the machine tool, the drive motor is mounted above the mounting platform, and the output shaft of the drive motor is perpendicular to the mounting platform. A mounting shaft is provided on one side of the drive motor, the mounting shaft is vertically mounted on the mounting platform, and the transmission gear is coaxially mounted on the mounting shaft.

[0013] Furthermore, one end of the mounting rod is fixedly connected to the top of the rotating lifting cylinder, and the axis of the mounting rod is perpendicular to the axis of the rotating lifting cylinder. The other end of the mounting rod extends vertically downward and is equipped with a telescopic device, which is a telescopic cylinder. The mounting rod is fixedly connected to the cleaning box in the cleaning tank through the telescopic cylinder. The telescopic cylinder drives the cleaning box to move up and down to enhance the cleaning effect.

[0014] Furthermore, the water exchange mechanism includes an inlet pipe and an outlet pipe located on the side of the cleaning tank away from the machine. The inlet pipe is located near the upper edge of the cleaning tank, and the outlet pipe is located at the bottom of one side of the cleaning tank. A water outlet valve is installed in the outlet pipe to control the water flow.

[0015] Furthermore, the machine platform is detachably and fixedly connected to the cleaning tanks on both sides.

[0016] Furthermore, the sidewalls and bottom of the cleaning box are provided with filter holes so that water in the cleaning box can be discharged through the filter holes.

[0017] This utility model has the following beneficial effects: 1. Addressing the problem that the cleaning box still needs to be manually moved, increasing labor costs and reducing production efficiency, this utility model eliminates the need for manual operation. The rotating lifting cylinder achieves up-and-down movement and rotation through a rotating device and lifting column. A mounting rod is provided on one side of the rotating lifting cylinder, allowing the cleaning box to be moved to the cleaning tank on the other side. 2. Addressing the problem that the cleaning box is merely stationary when placed in the cleaning tank, resulting in limited cleaning effectiveness, the installation arm is equipped with a telescopic cylinder that allows the cleaning box to move up and down in the water, achieving a better cleaning effect compared to stationary placement.

The rotary drive device enables the rotary lifting cylinder 3 to rotate in the rotary bearing 6 about the axis of the rotary lifting cylinder 3.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, preferably, the outer wall of the rotary lifting cylinder 3 is provided with teeth, and the teeth 31 are a plurality of strip-shaped protrusions 32 uniformly and vertically arranged on the outer wall of the rotary lifting cylinder 3.

The rotation surfaces of the drive gear 41, the transmission gear 42, and the rotary lifting cylinder 3 are coplanar. After the rotary drive gear 41 rotates, it drives the rotary lifting cylinder 3 to rotate through the transmission gear 42. After the rotary lifting cylinder 3 rises and falls, it is still meshed with the transmission gear 42.

[0028] like Figure 1 and Figure 2 As shown in the preferred embodiment, a horizontal mounting platform 45 is provided on one side of the machine base 8, the drive motor 4 is mounted above the mounting platform 45, and the output shaft of the drive motor 4 is perpendicular to the mounting platform 45.
