[0002] Carbon black paste is a color paste containing carbon black pigment. Carbon black paste is an important industrial raw material. It is made of carbon black powder through surface treatment, encapsulation and other processes and certain processing technology. Carbon black paste has good coloring, hiding and reinforcing properties, so it is widely used in many industries.

The central axis 60 rotating rod synchronously drives the pulley 2 314 to rotate, and the power is transmitted to the pulley 1 38 in combination with the transmission belt 39, thereby driving the matching shaft 1 310 and the matching gear 34 to rotate. During the rotation of the matching gear 34, the matching gear 34 engages with the inner gear ring 35. They mesh with each other, so that the matching slider 32 slides in the annular groove 31, carrying the inner wall cleaning mechanism 4 and the layered adding mechanism 5 at the bottom to rotate around the central axis 60. The inner wall cleaning mechanism 4 cleans the inner wall of the mixing tank 1 to prevent the carbon black from adhering to the inner wall of the mixing tank 1, and the layered adding mechanism 5 is combined with the lifting inner wall cleaning mechanism 4 and the rotating mechanism 3 to rotate the carbon black around the central axis 60 and add it into the raw materials in layers, further improving the mixing and stirring effect and accelerating the mixing efficiency and mixing quality of the carbon black slurry.

[0040] Further, such as Fig. 9 As shown, the inner wall cleaning structure includes a connecting frame 40 rotatably installed with the bottom center of the matching gear 34, the bottom of the connecting frame 40 is connected with a horizontal plate 41, and the end of the horizontal plate 41 close to the inner wall of the mixing tank 1 is provided with a side frame 42, and the side frame 42 is in contact with the inner wall of the mixing tank 1, and the horizontal plate 41 is located at the position of the connecting frame 40. A driving motor 43 is provided, and the driving motor 43 is connected to a lifting screw 44, and a limiting column 45 is provided at the bottom of the horizontal plate 41, and the limiting column 45 is arranged parallel to the lifting screw 44, and a horizontal plate 2 46 is installed between the limiting column 45 and the lifting screw 44, and the end of the horizontal plate 2 46 close to the inner wall of the mixing tank 1 is connected with an arc scraper 47, and the arc scraper 47 is arranged at an angle, and the arc scraper 47 is installed in contact with the inner wall of the mixing tank 1.

[0041] Specifically, after the power between the rotating mechanism 3 and the central axis 60 is connected, the gear 34 carries the inner wall cleaning mechanism 4 at the bottom to rotate around the central axis 60. At this time, the driving motor 43 is used to drive the lifting screw 44 to rotate, and the horizontal plate 46 is controlled to lift and lower. The rotating mechanism 3 drives the arc scraper 47 to contact the inner wall of the mixing tank 1. During the mixing and stirring process, the carbon black attached to the inner wall of the mixing tank 1 is scraped and cleaned, so that the carbon black re-participates in the mixing and stirring.

[0042] Further, such as Fig. 9As shown, the layered adding mechanism 5 includes a delivery pump 51 arranged on the top cover 11, the delivery pump 51 is connected to the carbon black tank, the delivery pump 51 is connected to a connecting pipe 52, a ferrule 1 53 and a ferrule 2 54 are rotatably mounted on the central shaft 60, the central shaft 60 is located in a partially hollow arrangement between the ferrule 1 53 and the ferrule 2 54, the connecting pipe 52 is connected to the ferrule 1 53, the end of the horizontal plate 1 41 facing the central shaft 60 is connected to the ferrule 2 54, a pipeline connected to the ferrule 2 54 is arranged in the horizontal plate 1 41, a telescopic hose 55 is arranged between the horizontal plate 1 41 and the horizontal plate 2 46, and extrusion heads 56 are evenly arranged on the bottom of the horizontal plate 2 46, and the extrusion head 56 is connected to the telescopic hose 55.

[0043] Specifically, in order to achieve the layered addition of carbon black into the mixing tank 1, a passage is arranged through the ferrule 1 53, the ferrule 2 54, and the hollow central shaft 60. After the delivery pump 51 delivers the carbon black into the connecting pipe 52, the ferrule 1 53 and the ferrule 2 54 are rotatably installed with the central shaft 60. After the carbon black enters the ferrule 1 53, it enters the central shaft 60, the ferrule 2 54, the horizontal plate 1 41, the telescopic hose 55, and finally reaches the extrusion head 56 at the bottom of the horizontal plate 2 46, thereby delivering the carbon black into the mixing tank 1. When the inner wall cleaning mechanism 4 performs the rotating, lifting, cleaning and scraping operation, the layered adding mechanism 5 is synchronously started to add the carbon black into the mixing tank 1 in layers, thereby effectively shortening the mixing time between the carbon black and the dispersant and improving the processing efficiency of the carbon black slurry.

[0044] When in use, the driving motor 43 drives the lifting screw 44 to rotate, thereby driving the horizontal plate 2 46 to lift and lower along the limiting column 45, thereby adjusting the height of the extruder head 56 at the bottom of the horizontal plate 2 46, and then adding the carbon black into the mixing tank 1 in layers. While the driving motor 43 drives the lifting screw 44 to rotate, the matching gear 34 and the inner gear ring 35 in the rotary mechanism 3 are meshed with each other, thereby carrying the horizontal plate 2 46 to rotate around the central axis of the mixing tank 1, realizing the spiral lifting movement of the horizontal plate 2 46, and then adding the carbon black into the mixing tank 1. At the same time, the layered adding mechanism 5, driven by the rotary mechanism 3, will make the inner wall cleaning mechanism 4 contact with the inner wall of the mixing tank 1, thereby scraping off the carbon black attached to the inner wall of the mixing tank 1 and re-participating in the stirring and mixing.

The lifting column 63 is located at the position of the gear shaft 65 and a matching rack 64 is arranged, and the matching rack 64 and the gear shaft 65 are meshed with each other.

[0046] Specifically, the lifting column 63 is controlled to be raised and lowered by the telescopic cylinder 61, and the stirring blade 66 is controlled to rotate in combination with the mutual engagement between the rack 64 and the gear shaft 65, so that the angle of the stirring blade 66 can be flexibly adjusted to improve the mixing effect.

[0047] Further, such as Fig.10 , Fig.11 As shown, the base support assembly 7 includes a fixed plate 70 arranged at the bottom of the mixing tank 1, and a matching groove 701 is arranged on the upper surface of the fixed plate 70, and a turntable 71 is installed in the matching groove 701, and the turntable 71 is evenly provided with first leakage holes, and the fixed plate 70 is evenly provided with second leakage holes at the position corresponding to the first leakage hole, and the end of the central axis 60 passes through the central part of the fixed plate 70 and the turntable 71, and the end of the central axis 60 is provided with a horizontal scraper 72, and the horizontal scraper 72 is installed in a fit with the upper surface of the turntable 71.

[0048] Specifically, in order to prevent the raw materials from accumulating at the bottom of the mixing tank 1 to form a dead corner and affect the mixing effect at the initial stage of mixing, the bottom of the mixing tank 1 is sealed by the fixed plate 70 and the rotating plate 71, and the bottom is scraped and stirred in real time by the horizontal scraper 72, so as to prevent the raw materials from accumulating at the bottom of the mixing tank 1. After the carbon black slurry is mixed, the first leakage hole and the second leakage hole on the rotating plate 71 are controlled to be misaligned, so that the carbon black slurry falls into the bottom of the mixing tank 1, and is discharged in conjunction with the discharge pipe 12.

The end of the spring column 74 is slidably installed between the annular groove 700.

[0050] Specifically, in order to prevent a large amount of carbon black slurry from adhering to the bottom and side walls of the mixing tank 1 during discharge, a bottom trough scraper 73 is provided to scrape the inner wall, and a spring column 74 is combined to ensure reliable contact between the bottom trough scraper 73 and the inner wall, thereby improving the scraping effect.

[0051] Further, such as Fig.12 As shown, a matching ball 710 is provided at the bottom of the rotating disk 71, and an arc-shaped limiting groove 702 is provided in the annular groove 700 of the fixed disk 70.

[0052] Specifically, the matching ball 710 and the arc-shaped limiting groove 702 are provided to facilitate the control of the relative position between the rotating disk 71 and the fixed disk 70. During the mixing and stirring stage, the end of the central shaft 60 is pressed on the central part of the rotating disk 71, so that the matching ball 710 on the rotating disk 71 is stuck at one end of the arc-shaped limiting groove 702. At this time, the first leakage hole and the second leakage hole are misaligned to form a closure. After the mixing and stirring is completed, the central shaft 60 is rotated in the opposite direction to drive the rotating disk 71 to rotate in the opposite direction, so that the matching ball 710 moves to the other end of the arc-shaped limiting groove 702. At this time, the first leakage hole and the second leakage hole are connected, thereby realizing the blanking process of the carbon black slurry.

[0053] A mixing process of the above-mentioned environmentally friendly carbon black slurry mixing system comprises the following steps: S1, putting raw materials except carbon black into a mixing tank 1, starting a mixing motor 2, and driving a mixing mechanism 6 to stir and mix in the mixing tank 1; S2, by controlling the telescopic motor 312 to shorten, the connecting plate 36 moves upward, so that the pulley 2 314 and the matching shaft 2 315 cooperate with each other, the central shaft 60 drives the pulley 2 314 to rotate synchronously, the transmission belt 39 transmits power to the pulley 1 38 and the matching gear 34, the matching gear 34 and the inner gear ring 35 mesh with each other, and drive the inner wall cleaning mechanism 4 and the layered adding mechanism 5 at the bottom to rotate around the central shaft 60; S3.

With the lifting and rotating motion of the inner wall cleaning mechanism 4, the carbon black is evenly layered and added into the mixing tank 1. The mixing mechanism 6 is used to complete the mixing of the carbon black slurry.

[0054] The working principle of the embodiment of the present invention is: like Figure 1-Figure 12As shown, by setting the annular frame 2 30 on the inner edge of the mixing tank 1, slidingly engaging the matching slider 32, and utilizing the mutual meshing between the matching gear 34 and the inner gear ring 35, when the connecting plate 36 is raised, the pulley 2 314 slides upward along the central axis 60, and cooperates with the matching shaft 2 315. The central axis 60 rotating rod synchronously drives the pulley 2 314 to rotate, and combines with the transmission belt 39 to transmit power to the pulley 1 38, thereby driving the matching shaft 1 310 and the matching gear 34 to rotate. During the rotation of the matching gear 34, the matching gear 34 is meshed with the inner gear ring 35. The inner wall cleaning mechanism 4 and the layered adding mechanism 5 are meshed with each other, so that the matching slider 32 slides in the annular slide groove 31, and the inner wall cleaning mechanism 4 and the layered adding mechanism 5 at the bottom rotate around the central axis 60. The inner wall cleaning mechanism 4 cleans the inner wall of the mixing tank 1 to prevent carbon black from adhering to the inner wall of the mixing tank 1, and the layered adding mechanism 5 is combined with the lifting inner wall cleaning mechanism 4 and the rotating mechanism 3 to rotate the carbon black around the central axis 60 and add it into the raw materials in layers, further improving the mixing effect and accelerating the mixing efficiency and mixing quality of the carbon black slurry. The height of the connecting plate 36 is controlled by the telescopic motor 312, and the sliding connection between the annular frame 110 and the clamping ball 311 is used to realize that the height of the connecting plate 36 can be flexibly adjusted at any angle by the rotating mechanism 3, thereby controlling the power switching between the central axis 60 and the rotating mechanism 3. After the power between the rotating mechanism 3 and the central axis 60 is connected, the gear 34 carries the inner wall cleaning mechanism 4 at the bottom to rotate around the central axis 60. At this time, the driving motor 43 is used to drive the lifting screw 44 to rotate, and the horizontal plate 46 is controlled to lift and lower. The rotating mechanism 3 drives the arc scraper 47 to contact the inner wall of the mixing tank 1. During the mixing and stirring process, the carbon black attached to the inner wall of the mixing tank 1 is scraped and cleaned, so that the carbon black can re-participate in the mixing and stirring. In order to achieve the addition of carbon black into the mixing tank 1 in layers, a passage is arranged through the ferrule 1 53, the ferrule 2 54 and the hollow central shaft 60. After the delivery pump 51 delivers the carbon black into the connecting pipe 52, the ferrule 1 53 and the ferrule 2 54 are rotatably installed with the central shaft 60. After the carbon black enters the ferrule 1 53, it enters the central shaft 60, the ferrule 2 54, the horizontal plate 1 41, the telescopic hose 55, and finally reaches the extrusion head 56 at the bottom of the horizontal plate 2 46, thereby delivering the carbon black into the mixing tank 1. When the inner wall cleaning mechanism 4 performs the rotating, lifting, cleaning and scraping operation, the layered adding mechanism 5 is synchronously started to add the carbon black into the mixing tank 1 in layers, thereby effectively shortening the mixing time between the carbon black and the dispersant and improving the processing efficiency of the carbon black slurry. In order to prevent the raw materials from accumulating at the bottom of the mixing tank 1 to form a dead corner and affect the stirring effect at the initial stage of stirring, the bottom of the mixing tank 1 is sealed by a fixed plate 70 and a rotating plate 71, and the bottom is scraped and stirred in real time by a horizontal scraper 72, thereby preventing the raw materials from accumulating at the bottom of the mixing tank 1.After the carbon black slurry is mixed, the carbon black slurry falls into the bottom of the mixing tank 1 by controlling the misalignment of the first leakage hole and the second leakage hole on the rotating disk 71, and is discharged in combination with the discharge pipe 12. The arrangement of the matching ball 710 and the arc-shaped limiting groove 702 facilitates the control of the relative position between the rotating disk 71 and the fixed disk 70. During the mixing and stirring stage, the end of the central shaft 60 is pressed on the central part of the rotating disk 71, so that the matching ball 710 on the rotating disk 71 is stuck at one end of the arc-shaped limiting groove 702. At this time, the first leakage hole and the second leakage hole are misaligned to form a closure. After the mixing and stirring is completed, the central shaft 60 is rotated in the opposite direction to drive the rotating disk 71 to rotate in the opposite direction, so that the matching ball 710 moves to the other end of the arc-shaped limiting groove 702. At this time, the first leakage hole and the second leakage hole are connected, thereby realizing the blanking process of the carbon black slurry.
