Description

Technical Field

[0001] The utility model relates to a mixing device, in particular to a rapid mixing device for powdered carbon black and granulating water. Background Art

[0002] During the production process of rubber, carbon black needs to be added to improve its reinforcing properties such as wear resistance, heat resistance, weather resistance and impact resistance. Therefore, carbon black is a very important additive for rubber products, especially rubber tires.

[0003] However, conventional carbon black is in powder form, while the carbon black required for adding to rubber is in granular form with the size of rice grains. This requires the use of a granulator to granulate the carbon black to obtain granular carbon black. Before granulating the powdered carbon black, it is necessary to first mix the powdered carbon black with granulating water, and then the mixed wet carbon black is discharged into the granulating device for granulation. However, the current mixing and stirring device is a conventional mixer, which takes a long time to stir to mix the granulating water and powdered carbon black. However, there will still be an uneven stirring phenomenon at the edge of the mixing kettle body, and the overall stirring effect on the powdered carbon black is not very ideal.

[0004] Therefore, the existing technology has the problem of unsatisfactory stirring effect. Content of the Utility Model

[0005] The purpose of the utility model is to provide a rapid mixing device for powdered carbon black and granulating water. The utility model has the characteristic of being able to effectively improve the stirring effect.

[0006] The technical solution of the utility model: A rapid mixing device for powdered carbon black and granulating water, including a mixing tank body. The bottom of the mixing tank body is an arc surface. In the middle of the top of the mixing tank body, there is a stirring mechanism. On the side of the stirring mechanism, there is a powdered carbon black feed pipe. At the bottom of the powdered carbon black feed pipe, there is a conical guide piece located inside the mixing tank body. The powdered carbon black feed pipe is sleeved with a granulating water feed sleeve. There is a granulating water channel between the bottom of the granulating water feed sleeve and the conical guide piece.

[0007] In the rapid mixing device for powdered carbon black and granulating water described above, the stirring mechanism includes a lifting component located at the top of the mixing tank body. On the lifting component, there is a stirring motor. The output end of the stirring motor is provided with a stirring shaft located inside the mixing tank body.

At the outer end of the transverse stirring rod, there is a vertical scraping plate that cooperates with the mixing tank body. At the upper and lower ends of the arc-shaped stirring paddle, there are spiral stirring paddles.

[0008] In the rapid mixing device for powdered carbon black and granulating water described above, on both sides of the top of the granulating water feed sleeve, there are water inlets. The water inlets are connected to a granulating water storage tank through pipelines.

[0009] In the aforementioned rapid mixing device for powdered carbon black and granulating water, the top of the powdered carbon black feed pipe is connected to a powdered carbon black storage tank through a pipeline.

[0010] In the aforementioned rapid mixing device for powdered carbon black and granulating water, a first anti-sticking coating is provided on the inner wall surface of the mixing tank body.

[0011] In the aforementioned rapid mixing device for powdered carbon black and granulating water, a second anti-sticking coating is provided on the surfaces of the stirring shaft, arc-shaped stirring paddles, horizontal stirring rods, and spiral stirring paddles.

[0012] Compared with the prior art, the utility model effectively improves the stirring effect between carbon black powder and granulating water by arranging a stirring mechanism in the middle of the mixing tank body and an inlet assembly composed of a powdered carbon black feed pipe, a conical guide, and a granulating water feed sleeve sleeved outside the powdered carbon black feed pipe on the side of the stirring mechanism. Specifically, in this application, the feeding of granulating water and the feeding of powdered carbon black are integrated. During the feeding process, the granulating water wraps around the powdered carbon black, which can not only effectively reduce dust but also enable the rapid mixing of powdered carbon black and granulating water, facilitating the improvement of the subsequent stirring speed. The stirring mechanism is composed of a lifting assembly, a stirring shaft, arc-shaped stirring paddles arranged on the stirring shaft, horizontal stirring rods, vertical scraping plates, and spiral stirring paddles, which is beneficial to effectively improving the stirring speed and quality, ensuring the mixing uniformity of the edge part, and improving the overall stirring and mixing effect.

Detailed Embodiments

[0015] The following further illustrates the utility model with reference to the drawings and embodiments, but it shall not be used as a basis for limiting the utility model.

[0016] Embodiment. A rapid mixing device for powdered carbon black and granulating water, with a structure as Figure 1As shown in the figure, it includes a mixing tank body 1. The bottom of the mixing tank body 1 is an arc surface 2. In the middle of the top of the mixing tank body 1, there is a stirring mechanism 3. On the side of the stirring mechanism 3, there is a powdered carbon black feed pipe 4. At the bottom of the powdered carbon black feed pipe 4, there is a conical guide piece 6 located inside the mixing tank body 1. The powdered carbon black feed pipe 4 is sleeved with a granulation water feed sleeve 7. Between the bottom of the granulation water feed sleeve 7 and the conical guide piece 6, there is a granulation water channel 5.

[0017] The stirring mechanism 3 includes a lifting assembly 301 located at the top of the mixing tank body 1. On the lifting assembly 301, there is a stirring motor 302. At the output end of the stirring motor 302, there is a stirring shaft 303 located inside the mixing tank body 1. At the bottom of the stirring shaft 303, there is an arc-shaped stirring paddle 304. In the middle of the stirring shaft 303, there is a transverse stirring rod 305. At the outer end of the transverse stirring rod 305, there is a vertical scraping plate 306 that cooperates with the mixing tank body 1. At the upper and lower ends of the arc-shaped stirring paddle 304, there are spiral stirring paddles 307.

[0018] On both sides of the top of the granulation water feed sleeve 7, there are water inlets, and the water inlets are connected to a granulation water storage tank through pipelines.

[0019] The top of the powdered carbon black feed pipe 4 is connected to a powdered carbon black storage tank through a pipeline.

[0020] The inner wall surface of the mixing tank body 1 is provided with a first anti-sticking coating.

[0021] The surfaces of the stirring shaft 303, the arc-shaped stirring paddle 304, the transverse stirring rod 305, and the spiral stirring paddle 307 are all provided with a second anti-sticking coating.

[0022] By setting the anti-sticking coating, it can effectively reduce the adhesion of wet materials on the inner wall surface of the mixing tank and the surfaces of the stirring shaft, the arc-shaped stirring paddle, the transverse stirring rod, and the spiral stirring paddle.

[0025] Working process of the utility model: Granulating water and powdered carbon black are fed into the mixing tank body in proportion. During the feeding process, the granulating water first flows in through the granulating water feeding sleeve, flows out through the outer surface of the conical guide member via the granulating water channel, forms a water curtain during the falling process, and wraps the powdered carbon black inside, which can effectively reduce dust. Then, the powdered carbon black drops from the powdered carbon black feeding pipe into the interior of the mixing tank body and contacts with some granulating water during the falling process to be pre-moistened. After the feeding is completed, the stirring mechanism starts to work. The stirring motor works to drive the stirring shaft to rotate, and the stirring shaft drives the rotation of the arc-shaped stirring paddle, the transverse stirring rod, the vertical scraping plate and the spiral stirring paddle, thereby effectively improving the stirring speed and stirring effect. Moreover, the vertical scraping plate can scrape the materials on the inner wall surface of the mixing tank body to prevent adhesion and accumulation, so that they can be mixed evenly. During the above process, the lifting assembly moves up and down regularly to change the positions of each stirring paddle, further improving the stirring uniformity.
