Description

Technical Field

[0001] The utility model relates to the technical field of carbon black powder processing, and specifically relates to a carbon black powder grinding device. Background Technique

[0002] The carbon black powder grinding device is a key equipment widely used in fields such as chemical industry, rubber, and plastics. Its main function is to process carbon black raw materials into powders with specific fineness and smoothness.

[0003] During the process of grinding the powder, if the feeding speed is too fast, some powders cannot be sufficiently rubbed and broken at the grinding treatment end. This is because the grinding media (such as grinding beads, grinding discs, etc.) in the grinding equipment require a certain amount of time and space to rub and break the powder. An overly fast feeding speed will cause some powder particles to not be able to fully contact between the grinding media, thereby reducing the mutual collision and shear force between the powder particles, and thus unable to produce effective crushing and grinding effects. This will result in a wide particle size distribution of the carbon black powder and cannot meet the requirements for powder fineness, affecting the quality and performance of the final product. Therefore, a carbon black powder grinding device is needed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a carbon black powder grinding device to solve the problem that the grinding cannot meet the powder fineness requirements due to too fast feeding in the above-mentioned background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A carbon black powder grinding device includes a device body, a grinding groove, a reduction motor, a turntable, a feed pipe, and a discharge pipe. The grinding groove is preset inside the device body. The reduction motor is installed on the top surface of the middle end of the device body. The turntable is movably connected to the inner surface of the grinding groove. The output end of the reduction motor is connected to a transmission shaft. The output end of the transmission shaft extends out of the device body through the inside of the turntable. The feed pipe is installed at the top of the device body, and the discharge pipe is installed at the bottom of the device body. A plurality of guide blocks and a plurality of convex blocks are equally spaced on the outer surface of the turntable. An air pressure groove is opened in the guide block and the turntable. The air pressure groove is slidably matched with a scraper. The center point of the device body and the center point of the turntable are eccentrically arranged, and the distance between the outer edge of the turntable and the inner edge of the grinding groove decreases from left to right.

[0006] One end of the outer surface of the transmission shaft is provided with an air seal disc. The inside of the air seal disc is a hollow structure. An air valve is installed inside the air seal disc. The air seal disc is snap-fitted to the outer surface of the transmission shaft. The hollow channel inside the air seal disc is connected to the ventilation channel. By opening the air valve and connecting it to an air pump, a certain air pressure value is maintained inside the ventilation channel, so that the scraper fits fully with the inside of the device body.

[0007] A ventilation channel is opened inside the turntable. A plurality of ventilation channels are annularly distributed along the central axis of the turntable and are interconnected.

[0008] The guiding block has a trapezoidal structure and is slidably connected to the outer surface of the scraper.

[0009] A screen is installed inside the discharge pipe, and the outer surface of one end of the screen is at the same horizontal level as the inner surface of the grinding groove.

[0010] Valves are respectively installed inside the feed pipe and the discharge pipe.

[0011] Compared with the prior art, the beneficial effects of the carbon black powder grinding device of the present utility model are as follows:

[0012] Through the optimized structure of the grinding treatment end, it is ensured that the powder can be fully rubbed and broken during the grinding process, thereby improving the grinding efficiency and the fineness uniformity of the powder.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-4 , the present utility model provides a technical solution: a carbon black powder grinding device, including a device body 1, a grinding groove 2, a reduction motor 3, a turntable 5, a feed pipe 8 and a discharge pipe 9. The grinding groove 2 is preset inside the device body 1, the reduction motor 3 is installed on the top surface of the middle end of the device body 1, the turntable 5 is movably connected to the inner surface of the grinding groove 2, the output end of the reduction motor 3 is connected to a transmission shaft 4, and the output end of the transmission shaft 4 penetrates through the inside of the turntable 5 and extends to the outside of the device body 1. The feed pipe 8 is installed at the top of the device body 1, and the discharge pipe 9 is installed at the bottom of the device body 1. Guide blocks 11 and bumps 16 are equidistantly distributed on the outer surface of the turntable 5. An air pressure groove 15 is provided inside the guide block 11 and the turntable 5, and the air pressure groove 15 is slidably matched with a scraper 12. The center point of the device body 1 and the center point of the turntable 5 are eccentrically arranged, and the distance between the outer edge of the turntable 5 and the inner edge of the grinding groove 2 decreases from left to right.

[0020] One end of the outer surface of the transmission shaft 4 is provided with an air seal disc 6. The inside of the air seal disc 6 is a hollow structure. An air valve 7 is installed inside the air seal disc 6. The air seal disc 6 is snap-connected to the outer surface of the transmission shaft 4. The hollow channel inside the air seal disc 6 is connected to a ventilation channel 14. By opening the air valve 7 and connecting it to an air pump, a certain air pressure value is maintained inside the ventilation channel 14, so that the scraper 12 is fully attached to the inside of the device body 1.

[0021] A ventilation channel 14 is provided inside the turntable 5, and a plurality of ventilation channels are annularly distributed along the central axis of the turntable 5 and are interconnected.

[0022] The guide block 11 is in a trapezoidal structure. The guide block 11 is slidably connected to the outer surface of the scraper 12. The outer surface of the guide block 11 has a certain arc, which can play a certain guiding role for the powder. During the sliding process, the powder can be shoveled upward to ensure that the carbon black powder always remains in a dispersed state and avoid being too viscous to affect the grinding effect.

[0023] A screen 13 is installed inside the discharge pipe 9, and one end of the outer surface of the screen 13 is at the same horizontal line as the inner surface of the grinding groove 2. The screen 13 provided inside the discharge pipe 9 can screen the powder during feeding. The corresponding mesh screen can be selected according to the required powder particle size. The screen is flush with the grinding groove 2, and the discharge pipe 9 is in a vertical state, which can realize automatic feeding by gravity. The particles smaller than the screen mesh diameter fall into the discharge pipe 9, thus realizing the effect of automatic feeding.

[0024] Valves 10 are respectively installed inside the feed pipe 8 and the discharge pipe 9, and the feed pipe 8 and the discharge pipe 9 realize the feeding or discharging operation by opening the valves 10.

[0025] Working principle: The six scrapers 12 distributed in a ring form six independent grinding areas. When ensuring the same amount of powder in each area, they will not affect each other. The feed pipe 8 evenly distributes the carbon black powder in each independent area. The reduction motor 3 drives the transmission shaft 4 and the turntable 5 to rotate inside the grinding groove 2. The grinding groove 2 and the turntable 5 are eccentrically arranged. When one end of the scraper 12 slides on the surface of the device body 1 and slides into the turntable 5, the air pressure generated by the sliding is used to make the other end of the scraper 12 slide out, so that the scraper 12 always fits against the inner wall of the device body 1. The scraper 12 can guide the powder. During the sliding process of the scraper 12 and the guide block 11, the guide block 11 can clean the powder on the surface of the scraper 12 by using the sliding action, avoiding the powder from infiltrating into the air pressure groove 15 and the ventilation channel 14. The powder is fully squeezed and broken at the position where the distance between the turntable 5 and the device body 1 is the smallest. The space generated by each adjacent guide block 11 and scraper 12 will expand or shrink with the rotation. It disperses when expanding and is squeezed and broken when shrinking, and the convex block 16 is used to further improve the crushing effect. A sieve mesh 13 is arranged inside the discharge pipe 9 to screen the powder for discharging. The corresponding mesh sieve can be selected according to the required powder particle size. The sieve mesh is flush with the grinding groove 2, and the discharge pipe 9 is in a vertical state, which can realize automatic feeding by using gravity. The particles smaller than the radial dimension of the sieve mesh fall into the discharge pipe 9, thus realizing the effect of automatic feeding.

[0026] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
