Description

Technical Field

[0001] The utility model belongs to the technical field of scraper structures of granulators, in particular to a novel scraper structure of a high-pigment special carbon black granulator. Background Art

[0002] High-pigment specialty carbon black is a carbon black material with high pigment properties. Carbon black is composed of fine particles of carbon, typically produced through the incomplete combustion or pyrolysis of hydrocarbons (such as natural gas or petroleum products). It is widely used in various fields, including rubber, plastics, inks, coatings, and other industries as a colorant, conductive agent, or reinforcing agent. High-pigment specialty carbon black is characterized by its excellent tinting strength and hiding power, making it particularly suitable for applications requiring a high concentration of black pigment. Compared with ordinary carbon black, high-pigment specialty carbon black may have higher purity, finer particle size, and better dispersibility. These characteristics help improve the quality and performance of the final product. High-pigment specialty carbon black is generally produced and formed using a disc pelletizer. The scraper, as a component of the disc pelletizer, ensures a more even distribution of the material on the disc, preventing material from accumulating in a certain area, thereby improving the efficiency and quality of pelletization.

[0003] For example, a high-efficiency and energy-saving disc granulator with publication number CN218047785U includes a base, and a circular groove block is welded on one side of the granulating disc of the base. The utility model can provide support force for the granulating disc at an inclined angle through the cooperation of the circular groove block, the ball bearing, the V-shaped block, the first U-shaped block and the first L-shaped block, thereby reducing the friction between the rotating rod, the first fixed bearing and the rectangular hole block on the disc granulator, so that the granulating disc can rotate efficiently and stably. With the cooperation of the second connecting block, the first bolt and the second U-shaped block, a certain support force can be provided for the first L-shaped block. Under the action of the protective shell, the rectangular block and the second bolt, the motor on the disc granulator can be protected. With the cooperation of the first circular block and the third connecting block, the stability between the rotating rod and the granulating disc on the disc granulator can be improved, thereby effectively improving the working efficiency of the disc granulator.

[0004] The scraper of the granulator is a fixed structure. After long-term use, a large amount of raw materials will stick to the outer wall of the scraper, which will not only lead to waste of raw materials but also affect the working efficiency of the scraper. In order to solve the above problems, a new scraper structure of high-pigment special carbon black granulator is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a new scraper structure for a high-pigment special carbon black granulator in order to solve the above problems, including:

[0006] A mounting plate, the bottom of which is fixedly mounted with a scraper body, the top of which is fixedly mounted with a connecting block, the upper surface of which is fixedly mounted with a slide rail, the outer wall of which is slidably connected to a limit slider, and one side of which is fixedly mounted with a motor;

[0007] The cleaning rod is fixedly mounted on the output shaft end of the motor. A plurality of connecting rods are equidistantly arranged at the lower end of the cleaning rod. A rotating rod is fixedly mounted on the lower end of each of the connecting rods. A cleaning pad is fixedly mounted on the outer wall of the rotating rod.

[0008] Through the above technical solution, during the operation of the scraper, the cleaning rod is driven to rotate by the motor. During the rotation of the cleaning rod, the connecting rod on its outer wall rotates along with its trajectory, so that the rotating rod at the lower end of the connecting rod is constantly in contact with the outer wall of the scraper. At this time, the cleaning pad on the outer wall of the rotating rod scrapes off the raw materials adhered to the outer wall of the scraper.

[0009] In a preferred embodiment, a friction pad is fixedly mounted on the bottom of the rotating rod.

[0010] Through the above technical solution, during the movement of the rotating rod, the friction pad at the bottom thereof contacts the disc granulator, thereby dispersing the material accumulated in the disc of the granulator and providing auxiliary cleaning effect for the scraper.

[0011] In a preferred embodiment, a rack is fixedly mounted on one side of the upper end of the connecting block, and a gear is fixedly mounted on the upper end of the cleaning rod, and the gear and the rack are meshed.

[0012] Through the above technical solution, during the rotation of the cleaning rod, it drives the gear to rotate with it. Since the gear is engaged with the rack, the cleaning rod moves during the rotation, thereby improving the cleaning effect of the scraper.

[0013] In a preferred embodiment, distance meters are fixedly mounted on both the left and right sides of the upper surface of the slide rail, and the distance meters are connected to the motor electrical signal.

[0014] Through the above technical solution, when the limit slider moves, the distance between it and the limit slider is detected by the distance meter. When the distance is too close, the electrical signal is transmitted to the motor to make it rotate in the opposite direction.

[0015] In a preferred embodiment, threaded holes are provided on both the left and right sides of the connecting block.

[0016] Through the above technical solution, the connecting block is connected to the granulator through the threaded hole.

[0017] In a preferred embodiment, the number of the connecting rods is four.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows: the present invention proposes a new scraper structure for a high-pigment special carbon black granulator.

[0019] During the operation of the scraper, the cleaning rod is driven to rotate by the motor. During the rotation of the cleaning rod, the connecting rod on its outer wall rotates along with its trajectory, so that the rotating rod at the lower end of the connecting rod is constantly in contact with the outer wall of the scraper. At this time, the cleaning pad on the outer wall of the rotating rod scrapes off the raw materials adhered to the outer wall of the scraper. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined Figure 1-3 The novel scraper structure of the high-pigment special carbon black granulator according to the embodiment of the present utility model is described in detail.

[0026] Example:

[0027] The new scraper structure of the high pigment specialty carbon black pelletizer includes:

[0028] The mounting plate 1 has a scraper body 2 fixedly mounted on its bottom, a connecting block 3 fixedly mounted on the top of the mounting plate 1, threaded holes are provided on both sides of the connecting block 3, and the connecting block 3 is connected to the granulator through the threaded holes. A slide rail 4 is fixedly mounted on the upper surface of the connecting block 3, and a limit slider 13 is slidably connected to the outer wall of the slide rail 4, and a motor 5 is fixedly mounted on one side of the limit slider 13;

[0029] The cleaning rod 6 is fixedly mounted on the output shaft end of the motor 5. A plurality of connecting rods 7 are equidistantly arranged at the lower end of the cleaning rod 6. The number of the connecting rods 7 is four. A rotating rod 8 is fixedly mounted on the lower ends of the plurality of connecting rods 7. A friction pad 10 is fixedly mounted on the bottom of the rotating rod 8. During the movement of the rotating rod 8, the friction pad 10 at the bottom contacts the disc granulator, thereby flushing out the materials accumulated in the granulator disc and providing auxiliary cleaning effect for the scraper. A cleaning pad 9 is fixedly mounted on the outer wall of the rotating rod 8. During the operation of the scraper, the cleaning rod 6 is driven to rotate by the motor 5. During the rotation of the cleaning rod 6, the connecting rod 7 on its outer wall rotates along with its trajectory, so that the rotating rod 8 at the lower end of the connecting rod 7 is constantly in contact with the outer wall of the scraper. At this time, the cleaning pad 9 on the outer wall of the rotating rod 8 scrapes off the raw materials adhered to the outer wall of the scraper.

[0030] A rack 12 is fixedly mounted on one side of the upper end of the connecting block 3, and a gear 11 is fixedly mounted on the upper end of the cleaning rod 6. The gear 11 and the rack 12 are engaged. During the rotation of the cleaning rod 6, it drives the gear 11 to rotate with it. Since the gear 11 is engaged with the rack 12, the cleaning rod 6 moves during the rotation, thereby improving the cleaning effect of the scraper. Distance meters 14 are fixedly mounted on both sides of the left and right sides of the upper surface of the slide rail 4. The distance meter 14 is electrically connected to the motor 5. When the limit slider 13 moves, the distance between it and the limit slider 13 is detected by the distance meter 14. When the distance is too close, the electrical signal is transmitted to the motor 5 to make it rotate in the opposite direction.

[0031] Working principle:

[0032] During the operation of the scraper, the cleaning rod 6 is driven to rotate by the motor 5. During the rotation of the cleaning rod 6, the connecting rod 7 on its outer wall rotates along its trajectory, so that the rotating rod 8 at the lower end of the connecting rod 7 is constantly in contact with the outer wall of the scraper. At this time, the cleaning pad 9 on the outer wall of the rotating rod 8 scrapes off the raw materials adhered to the outer wall of the scraper.
