Description

Technical Field

[0001] The present invention relates to the technical field of graphite material processing, and specifically to a raw material mixing device and a mixing method for graphite material production. Background Art

[0002] Graphite is an allotrope of carbon, a grayish-black, opaque solid with stable chemical properties, corrosion resistance, and is not easily reactive with chemicals such as acids and alkalis. It burns in oxygen to form carbon dioxide and can be oxidized by strong oxidants such as concentrated nitric acid and potassium permanganate.

[0003] In the process of graphite material production and processing, it is necessary to mix the raw materials to facilitate subsequent production and processing.

[0004] For example, Chinese Patent Publication No.: CN215196692U discloses a uniform mixing device for graphite material production, including a support seat. The middle part of the upper end of the support seat is rotatably connected with a rotating disk. The upper end of the rotating disk is fixedly connected with a mixing box body. The middle part of the upper end of the mixing box body is fixedly installed with a first driving motor. The output shaft of the first driving motor penetrates the upper surface of the mixing box body and is fixedly connected with a mixing rod. The outer circumferential surface of the mixing rod is equidistantly fixedly connected with a plurality of stirring blades. The lower end inside the mixing box body is fixedly connected with a horizontally arranged isolation bottom plate. The lower end of the mixing rod penetrates the upper surface of the isolation bottom plate and is rotatably connected with the inner wall of the lower end of the mixing box body.

[0005] In this solution, the mixing rod is rotated to drive a plurality of equidistant stirring blades to rotate, thereby stirring and mixing the graphite raw materials in the inner cavity of the mixing box. However, when the raw materials are put in, different raw materials can only be stacked together in sequence according to the putting order, and it is easy to appear a layering phenomenon between them, resulting in only a small part of different raw materials coming into contact, affecting the mixing effect of graphite.

[0034] See also Figure 1 、 Figure 2 and Figure 4 In an embodiment of the present invention, a raw material mixing device for graphite material production includes a shell 1, a stirring rod 6 is rotatably connected to the middle part of the inner cavity of the shell 1, and a plurality of symmetrical support plates 7 are fixedly connected to the outer wall of the stirring rod 6. The inner cavity of the support plate 7 is provided with a movable cavity 27, and a mixing mechanism is provided in the middle part of the inner cavity of the movable cavity 27. The mixing mechanism includes a cylinder 12, and the outer walls of both ends of the cylinder 12 are rotatably matched with the support plate 7. The outer wall of the cylinder 12 is fixedly connected to a plurality of driven rods 9. A driving mechanism for driving the cylinder 12 to rotate is provided in the middle part of the inner cavity of the stirring rod 6. When the driving mechanism moves upward, the cylinder 12 drives the plurality of driven rods 9 to rotate 180° synchronously.

[0035] See also Figure 2 The middle part of the upper end of the shell 1 is fixedly connected with a mounting plate 2, and the middle part of the upper side of the mounting plate 2 near the stirring rod 6 is transmission-connected with a servo motor 3. The output end of the servo motor 3 is transmission-connected with the middle part of the upper end of the stirring rod 6, that is, when the servo motor 3 is working, it will drive the stirring rod 6 to rotate horizontally, thereby driving the support plate 7 to rotate synchronously. The middle part of the upper side of the mounting plate 2 away from the servo motor 3 is transmission-connected with an electric telescopic push rod 4. The upper end of the shell 1 is fitted with a cover plate 5, and the output end of the electric telescopic push rod 4 is transmission-connected with the upper end surface of the cover plate 5, that is, the electric telescopic push rod 4 can drive the cover plate 5 to move in the vertical direction, thereby completing the blocking and unblocking of the shell 1. After unblocking, it is convenient to put raw materials for graphite material production (hereinafter referred to as "raw materials") into the inner cavity of the shell 1. Instead), several groups of symmetrical support plates 7 are fitted to each other in the vertical direction and rotate synchronously with the rotation of the stirring rod 6, so there is no relative movement between the several groups of symmetrical support plates 7. Therefore, when the driving mechanism has not yet driven the cylinder 12 and the driven rod 9 to rotate, there is no gap between the several groups of symmetrical support plates 7, and the inner cavity of the shell 1 is divided into four independent cavities of the electric telescopic push rod by the support plates 7.

[0036] Meanwhile, the top of the housing 1 is also divided into four feeding ports, which facilitates the input of different raw materials into different independent cavities. In this way, during the feeding process, the raw materials will not come into contact with each other, and the volume occupied by a single raw material in the inner cavity of the housing 1 is fixed, each only occupying one-fourth of the volume in the inner cavity of the housing 1. Thus, after different raw materials are put into the inner cavity of the housing 1, their heights are close to each other, increasing the contact area between different raw materials during mixing and improving the mixing rate. This avoids the situation where, when using a single feeding port and feeding raw materials sequentially, the raw materials fed first fill the bottom of the inner cavity of the housing 1, and the raw materials fed later can only accumulate on the previously added raw materials, resulting in only partial contact between different raw materials and unable to mix quickly.

[0037] Please refer to Figure 4 and Figure 9 , a movable cavity 27 is provided in the inner cavity of the support plate 7. Symmetric sleeve blocks 19 are vertically slidably connected in the inner cavity of the movable cavity 27. The outer walls at both ends of the cylinder 12 are respectively rotatably connected to the middle of the inner cavity of the sleeve block 19. A transmission plate 15 is horizontally slidably connected to one side of the inner cavity of the movable cavity 27 close to the stirring rod 6. A T-shaped groove 21 is provided in the middle of the side of the transmission plate 15 close to the sleeve block 19. A T-shaped block 20 is vertically slidably connected in the inner cavity of the T-shaped groove 21. One end of the T-shaped block 20 away from the sleeve block 19 is fixedly connected to a push rod 14. One end of the push rod 14 away from the T-shaped block 20 extends into the inner cavity of the cylinder 12. That is, when the transmission plate 15 horizontally moves away from the position where the stirring rod 6 is located, it will drive the T-shaped block 20 to move horizontally, thereby pushing the push rod 14 to move away from the position where the stirring rod 6 is located synchronously;

[0038] Please refer to Figure 4 and Figure 8, a mounting cavity 8 is formed in the middle of the inner cavity of the stirring rod 6. The driving mechanism includes a movable rod 11 which is vertically and slidably connected to the inner cavity of the mounting cavity 8. The top of the inner cavity of the mounting cavity 8 is drivingly connected with an electric push rod, and the output end of the electric push rod is drivingly connected with the movable rod 11. The movable rod 11 can be driven to move in the vertical direction through the mounting cavity 8. Symmetrical square grooves 13 are formed in the outer wall of the movable rod 11 near the middle of the support plate 7. The positions and numbers of the square grooves 13 correspond to those of the support plate 7. A transmission rod 16 is arranged between the square groove 13 and the transmission plate 15. One end of the transmission rod 16 is fixedly connected to the middle of the side of the transmission plate 15 away from the push rod 14, and the other end passes through the support plate 7 and the outer wall of the stirring rod 6 and extends into the inner cavity of the square groove 13. That is, the outer wall of the transmission rod 16 is horizontally slidably matched with the outer walls of the stirring rod 6 and the support plate 7. A round rod 17 is fixedly connected to the end of the transmission rod 16 away from the transmission plate 15. Symmetrical inclined grooves 18 are formed in the side wall of the inner cavity of the square groove 13, and the inclined grooves 18 are inclined towards the position where the adjacent support plate 7 is located. The end of the round rod 17 away from the transmission rod 16 is slidably matched with the inner cavity of the inclined groove 18. When the electric push rod pulls the movable rod 11 to move vertically upward, under the sliding cooperation of the inclined groove 18 and the round rod 17, the transmission rod 16 will be driven to horizontally move away from the center position of the movable rod 11, thereby pushing the transmission plate 15 and the push rod 14 to horizontally move away from the position where the stirring rod 6 is located.

[0039] Please refer to Figures 6-7 , two groups of cross keys 22 are fixedly connected to the outer wall of the side of the push rod 14 away from the transmission plate 15. Two guiding grooves 23 which are centrosymmetrically distributed about the center position of the cylinder 12 are formed in the inner cavity of the cylinder 12. The four corners of the cross keys 22 are respectively slidably matched with the inner cavities of the centrosymmetric guiding grooves 23. A horizontal groove 24 is formed at the end of the guiding groove 23 away from the transmission plate 15. When the push rod 14 drives the cross keys 22 to move horizontally, through the sliding cooperation between the cross keys 22 and the inner cavity of the guiding groove 23, and the push rod 14 and the cross keys 22 always maintain a horizontal state, the cylinder 12 will rotate along with the movement of the push rod 14 and the cross keys 22, and when the cross keys 22 move into the inner cavity of the horizontal groove 24, at this time, the cylinder 12 drives the driven rod 9 to rotate 180° and then remains stationary;

[0040] Please refer to Figure 3 , Figure 4 and Figure 6, and a through groove 10 adapted to the size of the driven rod 9 is formed in the outer wall of the support plate 7. When the driven rod 9 is in a vertical state, the driven rod 9 is located in the inner cavity of the through groove 10 at this time, thereby blocking the through groove 10, so as to ensure that during the process of feeding raw materials, the raw materials are separated from each other by the support plate 7 and the driven rod 9. After the push rod 14 drives the cross key 22 to move, the cylinder 12 drives the driven rod 9 to rotate 180°, and at this time the driven rod 9 is in a horizontal state, and at the same time the blocking of the through groove 10 is released, and the partition between the raw materials is also broken. Then, when the servo motor 3 drives the stirring rod 6 to drive the support plate 7 to rotate, the raw materials can be stirred and mixed in the horizontal direction through the support plate 7 with gaps, and through the cooperation of the cross key 22 and the horizontal groove 24, during the stirring and mixing process, the driven rod 9 is under the pressure of the raw materials and will continuously maintain a horizontal state.

[0041] Through the preliminary partition effect of several support plates 7, the stacking of raw materials layer by layer in the inner cavity of the housing 1 is avoided, and the phenomenon of raw material stratification occurs. During the horizontal stirring process, the contact area of the raw materials is increased, thereby improving the mixing effect and mixing rate of the raw materials. However, only through the horizontal stirring rod for stirring and mixing, when the amounts of different raw materials are different, that is, when the heights occupied by different raw materials during stacking in the inner cavity of the housing 1 are different, then during horizontal stirring, it is inevitable that the mixing degree of some raw materials is poor, which in turn affects the overall mixing effect of the raw materials.

[0042] Please refer to Figure 6 and Figure 10 , a groove 25 is formed at one end of the push rod 14 away from the transmission plate 15. A regulating rod 26 is slidably connected to one end of the inner cavity of the groove 25 away from the transmission plate 15. One end of the regulating rod 26 close to the transmission plate 15 is elastically connected to the side wall of the inner cavity of the groove 25 through a spring. Through the setting of the spring, when one end of the regulating rod 26 extending out of the push rod 14 is not subjected to an external force, the regulating rod 26 can be kept away from the side wall of the inner cavity of the groove 25. When the push rod 14 horizontally moves away from the position where the stirring rod 6 is located, it will drive the regulating rod 26 to move away from the position where the stirring rod 6 is located synchronously. When the push rod 14 drives the cross key 22 to move to the connection position of the horizontal groove 24 and the guiding groove 23, at this time, the vertical plane where one end of the regulating rod 26 away from the push rod 14 is located coincides with the vertical plane where one end of the cylinder 12 away from the stirring rod 6 is located. When the cross key 22 moves to one end of the horizontal groove 24 away from the guiding groove 23, at this time, the vertical plane where one end of the push rod 14 away from the stirring rod 6 is located coincides with the vertical plane where one end of the cylinder 12 away from the stirring rod 6 is located;

[0043] Please refer to Figure 11, and a movable groove 28 is formed in the middle of the side of the support plate 7 away from the stirring rod 6. The vertical height of the movable groove 28 is the same as the vertical height of the movable cavity 27, and the horizontal width of the movable groove 28 is the same as the horizontal width of the adjusting rod 26. At this time, the outer wall of the adjusting rod 26 is located in the inner cavity of the movable groove 28. When the end of the adjusting rod 26 away from the groove 25 contacts the inner cavity side wall of the housing 1, then the end of the adjusting rod 26 close to the stirring rod 6 will relatively contract into the inner cavity of the groove 25. In order to enable the raw materials to be stirred and mixed in both the horizontal and vertical directions in the inner cavity of the housing 1, a plurality of groups of symmetric arc grooves 30 are formed in the inner cavity side wall of the housing 1. The position of the arc groove 30 coincides with the central position of the support plate 7, and the number of groups of the arc grooves 30 corresponds to the number of groups of the support plates 7. When the adjusting rod 26 contracted into the inner cavity of the groove 25 moves to the position where the arc groove 30 is located as the support plate 7 rotates, then the end of the adjusting rod 26 away from the groove 25 is no longer squeezed, and then the adjusting rod 26 will extend into the inner cavity of the arc groove 30 under the action of elastic force.

[0044] Please refer to Figure 5 and Figure 10 , ∧-shaped arc grooves 29 and ∨-shaped arc grooves 31 are sequentially formed between every two of the three consecutive arc grooves 30. That is, among the three consecutive arc grooves 30, when an ∧-shaped arc groove 29 is formed between the middle arc groove 30 and any one of the arc grooves 30, then only a ∨-shaped arc groove 31 can be formed between the middle arc groove 30 and the other arc groove 30. When the adjusting rod 26 moves to the position where the arc groove 30 is located, at this time, under the action of elastic force, the adjusting rod 26 pops out from the movable groove 28 and enters the inner cavity of the arc groove 30. At this time, the adjusting rod 26 will rotate along with the support plate 7. Then, for the adjusting rod 26, it enters the inner cavity of the ∨-shaped arc groove 31 or the ∧-shaped arc groove 29. No matter which one of the ∧-shaped arc groove 29 and the ∨-shaped arc groove 31 the adjusting rod 26 enters, it will move in the vertical direction along the inner cavity of the movable groove 28, thereby driving the cylinder 12 to move in the vertical direction;

[0045] Please refer to Figure 5 , Figure 10 and Figure 11, specifically, when the adjusting rod 26 first enters the inner cavity of the ∧-shaped arc groove 29 from the inner cavity of the arc groove 30, the adjusting rod 26 will drive the cylinder 12 to move upward first until the top of the sleeve block 19 moves to the top of the inner cavity of the movable cavity 27. At this time, the adjusting rod 26 will move downward along the other side of the inner cavity of the ∧-shaped arc groove 29 and enter another arc groove 30. At this time, both the adjusting rod 26 and the cylinder 12 return to the initial position (i.e., the position when the cylinder 12 is in the middle of the inner cavity of the movable cavity 27). When the adjusting rod 26 enters one side of the inner cavity of the ∨-shaped arc groove 31, the adjusting rod 26 and the cylinder 12 will move downward until the lower part of the sleeve block 19 fits with the bottom of the inner cavity of the movable cavity 27. At this time, the adjusting rod 26 will move upward along the other side of the inner cavity of the ∧-shaped arc groove 29 and enter another arc groove 30. At this time, both the adjusting rod 26 and the cylinder 12 return to the initial position. That is, when the adjusting rod 26 enters the inner cavity of the arc groove 30, it will successively pass through the ∧-shaped arc groove 29, the arc groove 30, the ∨-shaped arc groove 31 or the ∨-shaped arc groove 31, the arc groove 30, the ∧-shaped arc groove 29. During the rotation process, the adjusting rod 26 will reciprocate this movement process, thereby driving the cylinder 12 to reciprocate vertically. When the cylinder 12 moves vertically, the push rod 14 will also drive the T-shaped block 20 to move vertically in the inner cavity of the T-shaped groove 21, while the transmission plate 15 remains stationary, thereby driving the driven rod 9 to reciprocate vertically, stirring and mixing the raw materials in the vertical direction, thereby improving the mixing effect and mixing rate of the raw materials, and avoiding the mixing effect from deteriorating due to the difficulty of the horizontally rotating stirring rod to apply a vertical force to the stratified raw materials after the raw materials are stratified.

[0046] Please refer to Figure 4 , Figure 6 , Figure 10 and Figure 11, a discharge port is provided at the lower part of the inner cavity of the housing 1. After the mixing is completed, the discharge port is opened, and the support plate 7 is continuously driven to rotate and the driven rod 9 is vertically reciprocated to continuously stir the raw materials so as to accelerate the raw materials to pass through the discharge port. After the discharging is completed, the movable rod 11 is driven to move downward by the electric push rod, so that the transmission rod 16 and the transmission plate 15 are reset, and then the cylinder 12 is driven to rotate 180° back to the initial position by the push rod 14, so that the driven rod 9 is again in the vertical state and continues to block the through groove 10. During the resetting process of the push rod 14, before the cylinder 12 rotates, the adjusting rod 26 will first contract into the movable cavity 27. Both the upper and lower ends of the sleeve block 19 are elastically connected to the top and bottom of the inner cavity of the movable cavity 27 through springs. When the adjusting rod 26 enters the inner cavity of the movable cavity 27, no matter where the adjusting rod 26 was located in the inner cavities of the ∧-shaped arc groove 29 and the ∨-shaped arc groove 31 before, the adjusting rod 26 will lose the traction effect on the cylinder 12. At this time, under the action of the elastic force, the sleeve block 19 will move to the middle position of the inner cavity of the movable cavity 27, thereby driving the cylinder 12 to reset, and at the same time, it also enables the driven rod 9 to just block the through groove 10 after rotation.

[0047] A method for mixing raw materials for the production of graphite materials, comprising the following steps:

[0048] S1: After driving the cover plate 5 to move upward by the electric telescopic push rod 4, raw materials are put into the inner cavity of the housing 1, and then the cover plate 5 is driven to move downward again to block the housing 1. Then, the movable rod 11 is driven to move upward by the electric push rod, and the transmission plate 15 and the push rod 14 are pushed to move horizontally through the transmission rod 16, thereby driving the cylinder 12 and the driven rod 9 to rotate 180°;

[0049] S2: The power of the servo motor 3 is turned on to drive the stirring rod 6 to drive the support plate 7 to rotate, so as to stir and mix the raw materials in the horizontal direction. During the rotation, the adjusting rod 26 enters the arc groove 30 and then cooperates with the ∧-shaped arc groove 29 and the ∨-shaped arc groove 31 to drive the cylinder 12 and the driven rod 9 to move in the vertical direction, thereby mixing the raw materials in the vertical direction.
