Description

Technical Field

[0001] This utility model relates to the technical field of graphite production equipment, specifically to a high-efficiency graphite powder mixer. Background Technology

[0002] Graphite powder is a mineral powder, mainly composed of elemental carbon. It is soft and blackish-gray. At room temperature, graphite powder is chemically stable and insoluble in water, dilute acids, dilute alkalis, and organic solvents. It can be used as refractory materials, conductive materials, etc. In the processing of graphite powder materials, mixing is often required, which necessitates graphite powder mixing equipment.

[0003] During the mixing process of graphite powder in a vertical mixer, multiple stirring blades are set on a rotating shaft driven by a motor to agitate the powder. However, this agitation method only agitates the graphite powder in one direction. When the stirring device agitates the graphite powder, the closer to the root of the stirring blades, the more frequently the graphite powder is agitated. Graphite powder farther from the rotating shaft often takes a long time to fully mix with other raw materials, resulting in low mixing efficiency of graphite powder. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a high-efficiency graphite powder mixer, which solves the problem of low mixing efficiency in existing vertical graphite powder mixers. When stirring graphite powder, the closer to the root of the stirring blades, the more frequently the graphite powder is agitated, while graphite powder farther from the rotating shaft often takes a long time to fully mix with other raw materials.

[0005] According to an embodiment of the present invention, a high-efficiency graphite powder mixer includes a cylindrical body. The top of the body has an inlet, and the bottom side wall has an outlet. A first motor is located in the central area of ​​the top of the body. The output end of the first motor extends into the body and is fixedly connected to a first stirring assembly. The first stirring assembly includes a rotating shaft fixed to the output end of the first motor and several first stirring blades evenly distributed on the shaft. The rotating shaft extends vertically to the bottom of the body. Several cylindrical first supports are also horizontally arranged radially along the cross-section of the body on the shaft. A second stirring assembly is rotatably connected to the end of the first support away from the rotating shaft. A receiving space is located inside the end of the first support away from the rotating shaft, and a second motor is also located within the receiving space. The second stirring assembly includes several second supports rotatably connected to the first supports. The second supports are located at the ends of the first supports away from the rotating shaft. The second motor drives the second supports and drives them to rotate around the axis of the first supports. A vibration device is also provided at the end of the second supports away from the first supports. Arc-shaped second stirring blades are also provided on the outer wall of the second support facing the inner wall of the body.

[0006] Furthermore, the feed inlet is provided with two ports and distributed on both sides of the first motor. The top of the feed inlet is also provided with a cover plate, and one side of the cover plate is hinged to one side of the top of the cylinder.

[0007] Furthermore, a valve is also provided on the discharge port.

[0008] Furthermore, the first stirring assembly also includes a pusher plate disposed at the bottom of the cylinder.

[0009] Furthermore, the end of the first stirring blade located at the bottom of the second stirring assembly and the feed inlet extends to the inner wall of the cylinder and is positioned close to it, and the first stirring blade located between the second stirring assembly and the push plate adopts the same configuration.

[0010] Furthermore, the second stirring assembly also includes a rotating seat disposed at the output end of the second motor, and the second bracket has four parts which are equidistantly fixed to the side wall of the rotating seat around the axis of the rotating seat.

[0011] Furthermore, the vibration device includes an ultrasonic transducer disposed at the end of the second support away from the first support. The ultrasonic transducer includes an arc-shaped broken ring disposed at the output end. The arc-shaped broken ring and the arc-shaped ring of the ultrasonic transducer disposed on other second supports can form a discontinuous circular ring structure.

[0012] Furthermore, the curvature of the second support and the second stirring blade is consistent with the curvature of the inner wall of the cylinder.

[0013] The technical principle of this utility model is as follows: When the operator puts graphite powder and other raw materials into the cylinder through the feed port, and then starts the first motor, the first motor drives the rotating shaft to rotate, and the first stirring blade begins to stir the graphite powder and other raw materials to mix. At the same time, the second motor located on the first support is started, and the second motor drives the second stirring assembly to start rotating around the axis of the first support. At the same time, the second stirring blade on the second stirring assembly moves and rotates synchronously. At this time, the rotation direction of the second stirring blade is perpendicular to the stirring direction of the first stirring blade, so that the stirring direction of the graphite powder is disrupted, and the situation of only unidirectional stirring is avoided. Then, after the vibration device located at the end of the second support is started, it begins to vibrate the stirred graphite powder, so that the graphite powder and other raw materials are mixed more quickly, thus solving the problem of low efficiency in graphite powder mixing.

[0026] The following is in conjunction with the appendix Figure 1 To be continued Figure 3 The embodiments further illustrate the technical solutions of this utility model.

[0027] like Figure 1 and Figure 2 As shown in the figure, this utility model embodiment proposes a high-efficiency graphite powder mixer, including a cylindrical body 1. The top of the body 1 is provided with a feed inlet 11, and the bottom side wall is provided with a discharge outlet 13. A first motor 2 is provided in the central area of ​​the top of the body 1. The output end of the first motor 2 extends into the interior of the body 1 and is fixedly connected to a first stirring assembly 3. The first stirring assembly 3 includes a rotating shaft 31 fixedly connected to the output end of the first motor 2 and a plurality of first stirring blades 32 evenly distributed on the shaft of the rotating shaft 31. The rotating shaft 31 extends vertically to the bottom area of ​​the body 1. A plurality of cylindrical first supports 33 are also horizontally arranged radially along the cross-section of the body 1 on the shaft of the rotating shaft 31. The end of the first support 33 away from the rotating shaft 31 is also rotatably connected to a second stirring assembly 5. The end of the first support 33 away from the rotating shaft 31 is also provided with a receiving space. The receiving space is also provided with a second motor 4. The second stirring assembly 5 includes a plurality of second supports 51 that are rotatably connected to the first support 33. The second supports 51 are located at the end of the first support 33 away from the rotating shaft 31. The second motor 4 drives the second supports 51 and drives the second supports 51 to rotate around the axis of the first support 33. The end of the second supports 51 away from the first support 33 is also provided with a vibration device 6. The outer wall of the second supports 51 facing the inner wall of the cylinder 1 is also provided with an arc-shaped second stirring blade 53.

[0028] Through the aforementioned mechanism, when the worker feeds graphite powder and other raw materials into the cylinder 1 through the feed inlet 11, and then starts the first motor 2, the first motor 2 drives the rotating shaft 31 to rotate, and the first stirring blade 32 begins to stir the graphite powder and mix with other raw materials. At the same time, the second motor 4 located on the first support 33 is started, and the second motor 4 drives the second stirring assembly 5 to start rotating around the axis of the first support 33. Simultaneously, the second stirring blade 53 on the second stirring assembly 5 rotates synchronously. At this time, the rotation direction of the second stirring blade 53 is perpendicular to the stirring direction of the first stirring blade 32, so that the stirring direction of the graphite powder is disrupted, thus getting rid of the situation where it can only be stirred in one direction. Then, the vibration device 6 located at the end of the second support 51 is started to vibrate the stirred graphite powder, so that the graphite powder and other raw materials are mixed more quickly, thus solving the problem of low efficiency in graphite powder mixing.

[0029] like Figure 1 and Figure 2 As shown, further, the feed inlet 11 is provided with two and distributed on both sides of the first motor 2. The top of the feed inlet 11 is also provided with a cover plate 12. One side of the cover plate 12 is hinged to one side of the top of the cylinder 1. The feed inlet 11 is provided with two, which facilitates the rapid addition of materials. The cover plate 12 on the feed inlet 11 can be closed to seal the entire cylinder 1, so that the mixing process is in a closed state and the dust of graphite powder during mixing will not drift out from the feed inlet 11.

[0030] like Figure 1 As shown, the discharge port 13 is further provided with a valve for sealing the bottom of the cylinder 1, and the valve can be an electronic valve to automate the control.

[0031] like Figure 1 As shown, the first stirring assembly 3 further includes a pusher plate disposed at the bottom of the cylinder 1. When the valve is closed, the pusher plate also plays a mixing and stirring role in the mixing process of graphite powder. When the valve is opened, the pusher plate rotates around the axis of the rotating shaft 31 and continuously pushes the graphite powder, and then the graphite powder is sent out from the opened valve.

[0032] like Figure 1 As shown, furthermore, the end of the first stirring blade 32 located at the bottom of the second stirring assembly 5 and the feed inlet 11 extends to the inner wall of the cylinder 1 and is positioned close to it. The first stirring blade 32 located between the second stirring assembly 5 and the push plate adopts the same arrangement, as shown. Figure 1 As shown, by increasing the length of the first stirring blades 32 at the top and bottom, the dead zones in the stirring area are reduced.

[0033] like Figure 1 and Figure 3As shown, the second stirring assembly 5 further includes a rotating seat 52 disposed at the output end of the second motor 4. The output end of the second motor 4 is fixedly connected to the bottom of the rotating seat 52. The second bracket 51 is provided with four brackets and is fixedly connected to the side wall of the rotating seat 52 at equal intervals around the axis of the rotating seat 52.

[0034] like Figure 1 and Figure 2 As shown, the vibration device 6 further includes an ultrasonic transducer 61 disposed at the end of the second support 51 away from the first support 33. The ultrasonic transducer 61 includes an arc-shaped broken ring 62 disposed at the output end. The arc-shaped broken ring 62 and the arc-shaped ring of the ultrasonic transducer 61 disposed on other second supports 51 can form a broken ring structure.

[0035] like Figure 1 and Figure 3 As shown, furthermore, the curvature of the second stirring blade 53 is consistent with the curvature of the inner wall of the cylinder 1.

[0036] like Figure 1 and Figure 3 as well as Figure 4 As shown, the bottom of the rotating shaft 31 can be connected to the bottom of the cylinder 1 via a bearing. Space can be provided inside the rotating shaft 31 and inside the second bracket 51 for the passage of power supply lines. A through-hole slip ring 7 can be installed at the bottom of the rotating shaft 31. The two interlocking rings of the through-hole slip ring 7 can rotate freely, thus supplying power to the second motor 4 while the rotating shaft 31 is rotating. Figure 3 As shown, the same structure can also be set inside the rotating seat 52 to supply power to the vibration device 6. The outer ring of the through-hole electric slip ring 7 is set inside the rotating seat 52 and fixed to the rotating seat 52. The inner ring is coaxially sleeved on the output end of the second motor 4. The output end of the second motor 4 extends through the inner ring and is fixed to the bottom of the rotating seat 52. When the second motor 4 drives the rotating seat 52 to rotate, the outer ring of the through-hole electric slip ring 7 rotates with the rotating seat 52. Since the inner ring is not fixed to the output end of the second motor 4, it can remain stationary. At this time, the power supply line is connected to the inner ring, and the rotating outer ring extends the power supply line to the vibration device 6 and supplies power to it.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
