The shaft 4 is eccentrically arranged, and a fixing rod 7 is fixed inside the inner container 2, and the fixing rod 7 is arranged opposite to the eccentric wheel 6. When the fixing rod 7 is squeezed by the eccentric wheel 6, the fixing rod 7 can drive the inner container 2 to move. When the fixing rod 7 is separated from the eccentric wheel 6, the inner container 2 will be reset under the action of a plurality of vibration springs 5. Therefore, with the operation of the motor 3, the inner container 2 can continuously generate a vibration effect. The vibrating inner container 2 makes it easy to generate gaps in the powdered raw materials inside, which is conducive to the plurality of stirring blades to break up the raw materials, thereby improving the stirring effect of the device on the raw materials.

[0022] The mixing tank 1 is provided with an exhaust assembly and a dust collection assembly, which includes a sealing cylinder 81, a sliding plug 82, an air bag 83, a return spring 84, a connecting rod 85, a fixing plate 86, two air pipes 87 and two one-way valves 88. The sealing cylinder 81 is fixed inside the mixing tank 1, the sliding plug 82 is slidably arranged on the inner surface of the sealing cylinder 81, the air bag 83 is arranged between the sealing cylinder 81 and the sliding plug 82, the return spring 84 is installed inside the air bag 83, one end of the connecting rod 85 is fixedly connected to the sliding plug 82, and the other end of the connecting rod 85 extends to the outside of the sealing cylinder 81 and is fixedly connected to the fixing plate 86. One end of the two air pipes 87 is connected to the air bag 83, and the two one-way valves 88 are respectively installed on the two air pipes 87. The limiting directions of the two one-way valves 88 are opposite. The dust collection assembly includes two fixing frames 91, an annular tube 92, a plurality of suction holes 93 and a dust collecting box 94, two fixing frames 91 are all fixed on the bottom surface of the mixing tank, the annular tube 92 is fixed on two fixing frames 91, and a plurality of air suction holes 93 are all opened on the annular tube 92. The dust collecting box 94 is arranged on the side of the mixing tank 1, one of the air pipes 87 is connected to the annular tube 92, and the other air pipe 87 is connected to the dust collecting box 94. During the process of the device stirring the raw materials, the plurality of air suction holes 93 on the annular tube 92 can absorb the dust generated during the discharging process and discharge the dust into the interior of the dust collecting box 94. This design can collect the dust and prevent the dust from flying around. The dust collecting box 94 is connected to the mixing tank 1 through a detachable structure, which is convenient for the staff to clean the carbon powder in the dust collecting box 94. In addition, the specific connection structure between the mixing tank 1 and the dust collecting box 94 is the prior art and is not an innovative part of the present technical solution. It is not shown in the figure and will not be described in detail here.

[0023] The specific working principle of the utility model is as follows:

[0024] When the graphite electric carbon production mixing device proposed by the utility model is in use, the staff puts the raw materials into the inner tank 2 and starts the motor 3. When the motor 3 is running, it drives the stirring shaft 4 to rotate. A plurality of stirring blades are arranged on the stirring shaft 4. The plurality of stirring blades stir and mix the raw materials as the stirring shaft 4 rotates. In addition, the stirring shaft 4 can also drive the eccentric wheel 6 to rotate. When the eccentric wheel 6 rotates, it can continuously squeeze the fixed rod 7. When the fixed rod 7 is squeezed by the eccentric wheel 6, the fixed rod 7 can drive the inner tank 2 to move. When the fixed rod 7 is separated from the eccentric wheel 6, the inner tank 2 will be reset under the action of the plurality of vibration springs 5. Therefore, with the operation of the motor 3, the inner tank 2 can continuously produce a vibration effect. The vibrating inner tank 2 makes it easy to produce gaps in the powdered raw materials inside it, which is conducive to the plurality of stirring blades to break up the raw materials, thereby improving the stirring effect of the device on the raw materials.

[0025] The eccentric wheel 6 can also continuously squeeze the fixed plate 86 while following the rotation of the stirring shaft 4. When the fixed plate 86 is squeezed, the fixed plate 86 can drive the sliding plug 82 to move through the connecting rod 85, so that the airbag 83 is squeezed. When the fixed plate 86 is separated from the eccentric wheel 6, the airbag 83 will be reset under the action of the reset spring 84. Therefore, with the rotation of the eccentric wheel 6, the airbag 83 can be continuously squeezed and restored. Since the limiting directions of the two one-way valves 88 are opposite, specifically, one of the one-way valves 88 limits the gas to only enter the airbag. Inside the airbag 83, another one-way valve 88 restricts the airflow to only flow out from the airbag 83. Therefore, when the airbag 83 is squeezed, the gas inside it will be pressed into the dust collecting box 94. When the airbag 83 recovers, the airbag 83 can draw the air in the annular tube 92. Based on the above process, when the device stirs the raw materials, the several suction holes 93 on the annular tube 92 can absorb the dust generated during the discharge process and discharge the dust into the dust collecting box 94. This design can collect the dust and prevent the dust from flying everywhere.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
