Description

Technical Field

[0001] The utility model relates to the field of screening, in particular to a carbon powder slag remover for carbon black production. Background Art

[0002] The goal of carbon black production is to produce carbon black particles with specific properties and purity. During the raw material pyrolysis or combustion process, in addition to carbon black, various impurities may be generated, such as residual raw materials that are not completely converted, ash, minerals, inorganic salts, and other non-carbon substances. Some organic substances or metal compounds in the impurities are high-economic compounds. Through slag removal, they can be separated and further recycled, which not only reduces the generation of waste but also increases economic benefits.

[0003] In the prior art, during carbon black production, in addition to fine carbon powder, various associated impurity particles of different specifications and sizes are also generated simultaneously. To ensure the purity of the output material, the associated impurities need to be manually screened and collected multiple times, resulting in low screening and slag removal efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to solve any of the above technical problems, and thus propose a carbon powder slag remover for carbon black production.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A carbon powder slag remover for carbon black production, including a slag screening barrel for screening carbon powder and slag, and a detachable upper cover arranged on the top thereof. An aggregate bin is arranged on the outer side of the bottom of the slag screening barrel, and a motor is fixedly arranged at the center of the bottom of the slag screening barrel. The slag screening barrel is in a hollow frustum shape. The inclined side wall of the bottom of the slag screening barrel is successively provided with annularly distributed first-stage screening holes, second-stage screening holes, and third-stage screening holes from bottom to top. The screen hole diameters of the first-stage screening holes, second-stage screening holes, and third-stage screening holes increase in sequence. A central shaft seat is arranged at the center of the bottom surface of the slag screening barrel, and a rotating screen plate is rotatably arranged in the central shaft seat.

[0006] Further, the center of the rotating screen plate is a rotating shaft. A connecting shaft platform is arranged at the bottom of the rotating shaft, and the connecting shaft platform is fixedly sleeved on the output shaft of the motor. A screening push plate with a bottom surface fitting and sliding with the inner wall of the bottom of the slag screening barrel is arranged on the side surface of the rotating shaft. The screening push plate is a trapezoidal folding plate with a 17.3° fold angle in the middle section.

[0007] Further, the aggregate bin is composed of multiple layers of hollow circular ring chambers, and each layer of circular ring chamber of the aggregate bin corresponds to the discharging area below the first-stage screening holes, second-stage screening holes, and third-stage screening holes respectively.

[0008] Further, a feeding hole is arranged at the center of the upper cover. The feeding hole is located above the central plane area of the bottom of the slag screening barrel, and handles are arranged on both sides of the upper cover.

[0009] The beneficial effects of the present utility model are as follows: The feeding hole of the upper cover is located above the central plane area at the bottom of the slag screening barrel. The inclined side wall at the bottom of the slag screening barrel is successively provided with first-stage screening holes, second-stage screening holes, and third-stage screening holes distributed in a circular ring from bottom to top. The diameters of the screening holes of the first-stage screening holes, second-stage screening holes, and third-stage screening holes increase in sequence. A rotating sieve plate is rotatably arranged through the center of the slag screening barrel. A screening push plate with a bottom surface fitting and sliding with the inner wall of the bottom of the screening barrel is arranged on the side of the rotating shaft. When the material falls into the slag screening barrel, the motor starts to drive the rotating sieve plate to rotate counterclockwise. The screening push plate of the rotating sieve plate pushes the material to be screened counterclockwise. Under the dual action of the thrust of the screening push plate and the centrifugal force of rotation, the material to be screened is successively pushed towards the first-stage screening holes, second-stage screening holes, and third-stage screening holes for screening. The aggregate bins below collect materials of different sizes, realizing single-time screening for slag removal and screening and collection of associated impurities of multiple different sizes at the same time.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Please refer to Figures 1 to 5 ;

[0017] This embodiment provides a slag remover for carbon powder used in carbon black production, which includes a slag screening barrel 1 for screening carbon powder slag and a detachable upper cover 3 arranged on the top thereof. An aggregate bin 2 is arranged on the outer side of the bottom of the slag screening barrel 1. A motor 4 is fixedly arranged at the center of the bottom of the slag screening barrel 1. The slag screening barrel 1 is in a hollow frustum shape. Circularly distributed first-stage screening holes 12, second-stage screening holes 13 and third-stage screening holes 14 are sequentially arranged on the inclined side wall of the bottom of the slag screening barrel 1 from bottom to top. The screen hole diameters of the first-stage screening holes 12, second-stage screening holes 13 and third-stage screening holes 14 increase in sequence. A central shaft seat 11 is arranged at the center of the bottom surface of the slag screening barrel 1. A rotating screen plate 5 is rotatably arranged in the central shaft seat 11.

[0018] Preferably, the center of the rotating screen plate 5 is a rotating shaft 51. A connecting shaft platform 53 is arranged at the bottom of the rotating shaft 51. The connecting shaft platform 53 is fixedly sleeved on the output shaft of the motor 4. A screening push plate 52 with a bottom surface fitting and sliding with the inner wall of the bottom of the slag screening barrel 1 is arranged on the side surface of the rotating shaft 51. The screening push plate 52 is a trapezoidal folding plate with a 17.3° angle fold in the middle section.

[0019] In a specific embodiment, the screening push plate 52 is a trapezoidal folding plate with a 17.3° angle fold in the middle section. When the rotating screen plate 5 rotates counterclockwise to push the material to be screened and removed, when the material is larger than the diameter of the screening hole below, the large-diameter material is pushed by the screening push plate 52 and at the same time under the action of centrifugal force, the large-diameter material climbs upward along the inclined side surface of the bottom of the slag screening barrel 1.

[0020] Preferably, the aggregate bin 2 is composed of multiple layers of hollow circular chambers. Each circular chamber of the aggregate bin 2 corresponds to the discharging area below the first-stage screening holes 12, second-stage screening holes 13 and third-stage screening holes 14 respectively.

[0021] Preferably, a feed hole is arranged at the center of the upper cover 3. The feed hole is located above the central plane area of the bottom of the slag screening barrel 1. Handles are arranged on both sides of the upper cover 3.

[0022] When the utility model is in use, the material to be screened and removed is poured into the slag screening barrel 1 through the feed hole of the upper cover 3. The motor 4 is started to drive the rotating screen plate 5 to rotate counterclockwise. The screening push plate 52 of the rotating screen plate 5 pushes the material to be screened counterclockwise. Under the dual action of the thrust of the screening push plate 52 and the centrifugal force of rotation, the material to be screened is sequentially pushed to the first-stage screening holes 12, second-stage screening holes 13 and third-stage screening holes 14 for screening. The aggregate bin 2 below the first-stage screening holes 12 collects the fine carbon powder, and the aggregate bins 2 below the second-stage screening holes 13 and third-stage screening holes 14 screen and collect other large-sized associated impurities.
