Description

Technical Field

[0001] This invention relates to the technical field of carbon black particle screening devices, specifically a rotary screening device with an external screen cylinder. Background Technology

[0002] Carbon black particle screening equipment is used to screen carbon black particles to remove particles that do not meet the requirements, thereby obtaining carbon black products that meet specific requirements. This equipment plays an important role in the carbon black production process, ensuring the quality and performance of carbon black products.

[0003] Common carbon black production particle screening devices typically use screens to screen carbon black particles. Carbon black that meets the requirements will fall through the screen holes into a collection box, while carbon black that does not meet the requirements will be intercepted by the screen, thus screening the carbon black particles.

[0004] However, during the screening of carbon black, the screen is prone to corrosion after long-term operation and needs to be replaced. The screen of the traditional rotary screen is built into the screen frame. When replacing it, the entire screen cylinder assembly needs to be removed from the shaft, the screen needs to be pulled out from the screen cylinder frame, and then the pre-rolled screen needs to be inserted into the gap between the screen cylinder frame and the slats and fixed. The installation process is complicated, the requirements for the replacement personnel are relatively high, and there is a possibility of damage to other parts during the replacement process. It is not easy to operate and reduces production efficiency. Summary of the Invention

[0005] To address the aforementioned problems, this utility model provides a rotary screening device with an externally mounted screen cylinder, thereby resolving the issues of complex screen replacement processes, difficulty in operation, and reduced production efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows.

[0007] A rotary screening device with an externally mounted screen includes a screen cylinder. Both ends of the screen cylinder are supported by angle steel rings. The front angle steel rings have a smaller diameter, while the rear angle steel rings have a larger diameter. Multiple bushings are fixedly connected to the inner walls of the angle steel rings by multiple supporting round steel rings. The bushings are located at the center of the angle steel rings at both ends. Multiple long strips are fixedly connected between the angle steel rings at both ends along their length. Multiple long strips are evenly arranged around the circumference of the angle steel rings. A ring of circumferential supporting strips is arranged at the middle of the long strips. A screen is installed on the outer walls of the angle steel rings and the outer walls of the strips. Pressure strips are provided on the outer side of the screen, corresponding to the strips and the angle steel rings, and are fixedly connected by bolts. The nuts of the bolts are fitted onto the outer side of the pressure strips.

[0008] An even number of baffles are fixedly installed at the rear end of the screen cylinder. The curvature of the baffles is slightly greater than 180°, and the baffles are arranged symmetrically above and below.

[0009] The beneficial effects of this utility model are:

[0010] Replacing the screen is convenient and does not require the complete dismantling of the screen frame. Simply rotate the screen assembly to remove the old screen from the outside and reinstall the new screen. The operation is simple and convenient, and the maintenance time is short.

[0011] The screen does not need to be pre-rolled. After the screen is placed externally, it can be rolled onto the screen frame from the outside, making installation convenient and reducing operation steps. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] A rotary screening device with an externally mounted screen includes a screen cylinder supported at both ends by angle steel rings. The front angle steel rings have a smaller diameter, while the rear angle steel rings have a larger diameter. Multiple supporting round steel rings are fixedly connected to bushings on the inner walls of the angle steel rings, with the bushings located at the center of the angle steel rings at both ends. Multiple long strips are fixedly connected between the angle steel rings at both ends along their length, with multiple strips evenly arranged around the circumference of the angle steel rings. A ring of circumferential supporting strips is arranged at the middle of the length of each strip. A screen is installed on the outer walls of the angle steel rings and the strips. Pressure strips are provided on the outer side of the screen, corresponding to the strips and angle steel rings, and are fixedly connected by bolts. The nuts of the bolts are fitted onto the outer side of the pressure strips. When the screen needs to be replaced, simply loosen the nuts and remove the pressure strips to remove the screen from the outside. When installing a new screen, the screen does not need to be pre-rolled; simply roll a screen of the appropriate length onto the screen frame from the outside, and then fix it using pressure strips and nuts. The operation is simple and the installation is convenient.

[0018] An even number of baffles are fixedly installed at the rear end of the screen cylinder. The curvature of the baffles is slightly greater than 180°, and the baffles are arranged symmetrically at the top and bottom. The outer curvature of the baffles is longer than that of the inner curvature, which makes the material screening more thorough and effectively prevents qualified materials from being screened into the unqualified product bin.
