Description

Technical Field

[0001] The present application relates to the technical field of granulation kettles, and in particular to a novel stirring mechanism for a coated granulation kettle. Background Art

[0002] During the production process of artificial graphite, the raw material particles need to be coated and granulated to improve the defects of the particles. Due to the ratio of petroleum coke powder and asphalt in the granulation materials, the materials have a certain adhesiveness. The temperature of the granulation process reaches 500-600℃, and the materials are easily adhered to the stirring blades. The current granulation kettles are all double-ribbon type. If the spiral belt is wide, it is easy for materials to accumulate. The materials are easy to stick to the spiral belt and affect the effect of the next granulation. In addition, there are more residual materials in the granulation kettle. If the spiral belt is too narrow, the materials cannot be fully stirred evenly during the granulation process, and the materials are easy to agglomerate. Utility Model Content

In this embodiment, the outer coulter and the inner coulter are both rotatably connected to the cross bar, and the angle is locked by a top screw, thereby realizing the adjustment of the inclination angle, which is convenient for selecting a suitable inclination angle according to the viscosity of the material.

[0009] In a specific embodiment, the outer coulter pushes the material upward and the inner coulter pushes the material downward.

It should be noted that the cross bar is located on the lower surface of the outer coulter, and the cross bar is located on the upper surface of the inner coulter. In this way, the extrusion surface of the material and the coulter is smooth and has no protrusions, which can further reduce material adhesion.

[0011] In a specific embodiment, only the outer coulters are provided on the bottom layer.

[0012] In the above implementation process, the lower end of the kettle body is closed, and the material is returned upward by the external plowshare, which is beneficial to the circulation of the material in the kettle body.

[0013] In a specific embodiment, the inclination angle of the outer coulter and the inner coulter is 60°, and the gap between the outer coulter and the inner wall of the kettle body is 1-3 cm.

[0014] In the above implementation process, the plow blade with a large inclination angle can minimize the adhesion of materials while ensuring the stirring effect.

[0015] In a specific embodiment, a lower scraper is provided at the discharge port at the lower end of the kettle body, and the gap between the lower scraper and the inner wall of the kettle body is 1-3 cm.

[0016] During the above implementation process, the lower scraper cleans the material at the discharge port to prevent material blockage.

[0017] In a specific embodiment, an upper scraper is provided at the kettle cover at the upper end of the kettle body, and the gap between the upper scraper and the kettle cover is 1-3 cm.

[0018] In the above implementation process, the upper scraper scrapes the material on the upper wall of the kettle body to reduce residue.

[0019] Compared with the prior art, the beneficial effects of the present application are: utilizing the outer coulter and the inner coulter with opposite inclination directions to circulate and stir the material, and the setting of a large inclination angle can reduce the adhesion of the material.

[0025] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0026] See also Figure 1-Figure 3 The present application provides a novel stirring mechanism for a coated granulation kettle, comprising a kettle body 10, a central shaft 20 rotatably connected thereto, a crossbar 30 arranged in a circumferential array on the central shaft 20, and outer coulters 40 and inner coulters 50 disposed on the crossbar 30. The outer coulters 40 and inner coulters 50 are inclined at an angle of 30-60° and in opposite directions. The central shaft 20, inner coulters 50, and outer coulters 40 are all mirror-polished. The outer coulters 40 and inner coulters 50, inclined in opposite directions, are utilized to circulate and stir the material, and the large inclination angle can reduce material adhesion.

[0027] See also Figure 1-Figure 3 , 4-8 layers of coulters are arranged on the central axis 20, and the spacing between the upper and lower layers of coulters does not exceed 20 cm. Five layers of coulters are arranged, and three cross bars 30 are arranged on each layer.

[0028] See also Figure 1-Figure 3 Each layer is provided with 4-6 coulters, including 2-4 inner coulters 50 and 2-4 outer coulters 40. The outer coulters 40 are provided at the outer end of each crossbar 30, and the inner coulters 50 are provided at the inner end of each crossbar 30. In this embodiment, the outer coulters 40 and the inner coulters 50 are both rotatably connected to the crossbar 30 and locked at an angle by a top screw, thereby achieving adjustment of the tilt angle, making it easy to select a suitable tilt angle according to the viscosity of the material.

[0029] See also Figure 1-Figure 3 The outer coulter 40 pushes the material upward, and the inner coulter 50 pushes the material downward. During mixing, the outer coulter 40 pushes the material upward, and the inner coulter 50 pushes the material downward. It should be noted that the cross bar 30 is located on the lower surface of the outer coulter 40, and the cross bar 30 is located on the upper surface of the inner coulter 50. In this way, the extrusion surface between the material and the coulter is smooth and has no protrusions, which can further reduce material adhesion.

[0030] See also Figure 1-Figure 3, the bottom layer is only provided with outer coulter 40. The lower end of the kettle body 10 is provided with a closing opening, and the material is returned upwards by the outer coulter 40, which is conducive to the circulation of the material in the kettle body 10.

[0031] See also Figure 1-Figure 3 The outer coulter 40 and the inner coulter 50 have an inclination angle of 60°, and the gap between the outer coulter 40 and the inner wall of the kettle body 10 is 1-3 cm. The coulter with a large inclination angle can minimize the adhesion of materials while ensuring the stirring effect.

[0032] See also Figure 1-Figure 3 A lower scraper 60 is provided at the discharge port at the lower end of the kettle body 10, and the gap between the lower scraper 60 and the inner wall of the kettle body 10 is 1-3 cm. The lower scraper 60 cleans the material at the discharge port to prevent the discharge from being blocked.

[0033] See also Figure 1-Figure 3 An upper scraper 70 is provided at the kettle cover at the upper end of the kettle body 10, and the gap between the upper scraper 70 and the kettle cover is 1-3 cm. The upper scraper 70 scrapes the material on the upper wall of the kettle body 10 to reduce residue.

[0034] The working principle of the stirring mechanism of the new coated granulation kettle is: when the material is granulated in the coated granulation kettle, the outer coulter 40 flips the material upward, and the inner coulter 50 flips the material downward to fully disperse the material. The inclination angle of the coulter is large, and there is basically no residual material. The upper scraper 70 and the lower scraper 60 scrape the material on the upper and lower walls of the kettle body 10 to reduce residue. The lower scraper 60 can also clean the material at the discharge port to prevent blockage of the discharge. The middle axis 20, cross bar 30, inner coulter 50, outer coulter 40, upper scraper 70 and lower scraper 60 are all mirror polished to further reduce material adhesion. In summary, the outer coulter 40 and the inner coulter 50 with opposite inclination directions are used to circulate and stir the material. The setting of a large inclination angle can reduce the adhesion of the material.
