In the production process of clean coal, qualified raw coal is generally purchased from the coal preparation plant. After crushing, screening and metering, the raw coal is mixed with asphalt, tar, additives, etc., and then heated and kept warm. After heating and keeping warm, it is molded to obtain semi-finished coal. The semi-finished coal enters the carbonization furnace for carbonization, and finally the finished coal is obtained after quenching. Among them, a kneading device is needed during the mixing and kneading, which is used to mix the raw coal and asphalt, tar, additives, etc. evenly, so as to facilitate the subsequent molding.

The utility model is used for processing clean coal. Specifically, the utility model is used for kneading raw coal, asphalt, tar, additives and other materials. During operation, the materials are quantitatively added into the shell 1 through the feed port, and the driving mechanism is started. The driving mechanism drives the vertical pipe 5 and the vertical shaft 6 to rotate at the same time, and the rotation directions of the vertical pipe 5 and the vertical shaft 6 are opposite. When the vertical pipe 5 rotates, the vertical cylinder 2 is first driven to rotate through a horizontal rod 4 located at the top, and the vertical cylinder 2 then drives the spiral plate 3 and all the remaining horizontal rods 4 to rotate, and the horizontal rod 4 drives a part of the stirring mechanism 8 to rotate. In this process, the stirring mechanism 8 on the horizontal rod 4 rotates to the shell The material in the body 1 is stirred. At the same time, due to the rotation of the spiral plate 3, a spiral conveying effect is produced, which generates a downward thrust on the material in the annular space between the vertical cylinder 2 and the side wall of the shell 1, so that the material in the annular space moves downward until it reaches the bottom of the shell 1 and moves toward the middle of the shell 1, and pushes the material inside the vertical cylinder 2 to move upward, and the material on the upper layer moves outward into the annular space, forming a material flow cycle; at the same time, when the vertical shaft 6 rotates, it drives the rotating rod 7 to rotate, and the rotating rod 7 drives another part of the stirring mechanism 8 to rotate to stir the material. In the utility model, the vertical cylinder 2 and the spiral plate 3 are arranged so that the material can circulate in the shell 1. During the circulation of the material, the mixing of the material in each height layer is promoted, so that the material in each height layer has a consistent mixing degree, and the uniformity of the overall material mixing is improved; secondly, the utility model is provided with a two-part stirring mechanism 8, one part of the stirring mechanism 8 is installed on the cross bar 4, and the other part of the stirring mechanism 8 is installed on the rotating rod 7. The two parts of the stirring mechanism 8 rotate in opposite directions and are alternately arranged with each other, which solves the problem of the traditional stirring mechanism 8 having a fixed rotation direction and a single structure, can shorten the mixing time of the material, and improve the mixing efficiency and mixing effect of the material.

A scraper 9 is provided at the lower end of the vertical shaft 6, and the lower side of the scraper 9 is in line with the bottom of the housing 1. Considering that the material at the bottom of the housing 1 has a relatively poor stirring and kneading effect on the one hand, and the material at this position is also easy to adhere to the bottom of the housing 1 on the other hand, a scraper 9 is provided to solve the above problems, which can not only promote the mixing of this part of the material and improve the kneading effect, but also can timely scrape off the material adhering to the bottom of the housing 1 to ensure the normal operation of the device.

The driving mechanism includes a forward motor 10 and a reverse motor 11 installed on the top of the housing 1. The output shaft of the forward motor 10 is connected to the upper end of the vertical shaft 6. A driven gear 12 is provided on the vertical tube 5 above the housing 1. A driving gear 13 meshing with the driven gear 12 is installed on the output shaft of the reverse motor 11. Both the forward motor 10 and the reverse motor 11 are existing motors. During use, the two respectively drive the vertical tube 5 and the vertical shaft 6 to rotate, and the vertical tube 5 and the vertical shaft 6 rotate in opposite directions. During operation, the forward motor 10 drives the vertical shaft 6 to rotate, and the reverse motor 11 drives the driving gear 13, the driven gear 12 and the vertical tube 5 to rotate in turn. The specific structure of the driving mechanism can also use other structures, as long as it can drive the vertical tube 5 and the vertical shaft 6 to rotate in the opposite directions at the same time.

A material throwing plate 14 is provided on the vertical tube 5 above the vertical cylinder 2. After the raw coal is mixed with materials such as asphalt, it has a large viscosity and the fluidity of the materials is poor. In the present utility model, in order to realize the circulation of materials, the materials located in the upper layer need to be moved outward so that these materials can enter the annular space between the vertical cylinder 2 and the shell 1. However, due to the high viscosity of the materials, the speed of moving outward is slow, and the materials may be stuck on the top of the shell 1 and cause a blockage problem. In order to solve this problem, a material throwing plate 14 is provided. The material throwing plate 14 is installed on the vertical tube 5 and rotates with the vertical tube 5. During the rotation process, the material can be driven to rotate. Under the action of centrifugal force, the material quickly moves outward, which can solve the problem of slow material flow speed. At the same time, due to the existence of the material throwing plate 14, the problem of material blockage is also solved.

The vertical shaft 6 is provided with a spiral blade 15. Generally speaking, the material in the middle of the housing 1, i.e., near the vertical shaft 6, has a lower rotational linear velocity, and the stirring effect of this part of the material is slightly worse than that of the material in other parts. After the spiral blade 15 is provided, on the one hand, it can promote the movement of this part of the material in the vertical direction, and on the other hand, it can promote the mixing of this part of the material, thereby improving the mixing effect of the overall material.

A collar 16 is mounted on the vertical shaft 6 below the vertical cylinder 2, and a gap is left between the collar 16 and the vertical shaft 6. The collar 16 is fixedly connected to the side wall of the housing 1 by a connecting rod 17. When the utility model is in operation, the vertical shaft 6 drives the rotating rod 7 to rotate, and the rotating rod 7 drives a part of the stirring mechanism to rotate. Since the lower end of the vertical shaft 6 is not positioned, as the operation time increases, the lower end of the vertical shaft 6 may have problems such as shaking or swinging, which easily affects the normal operation of the device. In order to avoid the above problems, a collar 16 and a connecting rod 17 are provided, and a gap is left between the collar 16 and the vertical shaft 6. On the one hand, the vertical shaft 6 can rotate freely in the collar 16. On the other hand, since only a gap is left between the collar 16 and the vertical shaft 6, and the gap is usually small, the vertical shaft 6 will not have a large shaking and swinging. The combination of the connecting rod 17 and the collar 16 has an effective limit positioning effect on the vertical shaft 6, which can reduce the shaking and swinging problems that occur during the rotation of the vertical shaft 6 and extend the service life of the vertical shaft 6.
