Description

Technical Field

[0001] This utility model relates to the field of drum screens, and in particular to a drum screen for the production of refractory materials. Background Technology

[0002] Refractory materials are fundamental materials in the field of high-temperature technology and are widely used. Among them, the most common applications are as structural materials and linings to resist high temperatures in various thermal equipment and high-temperature containers. In the production process of refractory materials, raw materials generally need to be crushed and ground and then screened before entering the next process.

[0003] A search revealed Chinese Patent Publication No. CN222402201U, which discloses a rotary drum screen for refractory material production. This patent includes a hollow mounting frame, a screening mechanism, and a drive mechanism. The hollow mounting frame consists of two hollow mounting frames whose lower ends are fixedly connected by a bracket. The screening mechanism includes a limiting rotating ring, a limiting rotating groove, and a rotating cylinder. The rotating cylinder is rotatably connected to the interior of the two hollow mounting frames. Each hollow mounting frame has a limiting rotating ring on its inner arc surface, and each rotating cylinder has a limiting rotating groove on its outer arc surface. Both limiting rotating rings are rotatably connected to the interior of their corresponding limiting rotating grooves. A screen is positioned between the two rotating cylinders. The drive mechanism is located between the two hollow mounting frames and is fixedly fitted to the screening mechanism. This device avoids the problems of slag splashing and excessive smoke while screening refractory materials, and also prevents small particles from getting stuck in the drive mechanism and causing the rotary drum screen to malfunction. Currently, when using refractory material production drum screens to screen refractory materials, the speed at which the refractory material passes through the drum screen is positively correlated with the tilt angle. In actual use, the feeding and unloading speeds often do not match the actual speed at which the material passes through the device. This can lead to situations where there is too much material accumulating at a certain moment or too little material in the drum screen. It is difficult to achieve dynamic adjustment of the feeding speed, resulting in a decrease in screening accuracy and efficiency. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] The present invention will be further described below with reference to the accompanying drawings: like Figure 1 — Figure 6 As shown, a rotary screen for refractory material production includes a support 101. A bottom shell 102 is bolted to the inside of the bottom side of the support 101. A closed door 103 is provided on one side of the bottom shell 102. A support mechanism is provided on the bottom shell 102. The support mechanism includes several mounting blocks 201. The mounting blocks 201 are bolted to the four corners inside the bottom shell 102. An elastic telescopic rod 202 is fixedly installed inside the mounting block 201. A support block 203 is provided at one end of the elastic telescopic rod 202. An mounting ring 204 is bolted to the support block 203. An inclined mounting cylinder 205 is welded to the mounting ring 204. A rotary screen mechanism is provided inside the mounting cylinder 205. A conveying mechanism is provided at one end of the mounting cylinder 205. A feeding mechanism is provided at the top of the support 101. The feeding mechanism includes an inclined plate 501. A rotating shaft 502 is bolted to the upper part of the inclined plate 501. The rotating shaft 502 is rotatably connected to the inner side of the support 101. The refractory material to be screened is conveyed to the upper part of the inclined plate 501. The refractory material raw material is guided by the inclined plate 501 and enters the rotary screen mechanism for screening through the conveying mechanism. A transmission component is set at the lower part of the inclined plate 501. The other end of the transmission component is installed on the mounting ring 204. The transmission component is used to reduce the tilt angle of the inclined plate 501 when there is an excessive amount of refractory material in the rotary screen mechanism. When the amount of refractory material in the rotary screen mechanism is too small, the tilt of the inclined plate 501 can be appropriately increased. In this way, dynamic adjustment is achieved so that the amount of refractory material in the screen cylinder 302 is within a suitable range to achieve the best screening efficiency.

[0020] In this embodiment, the transmission assembly includes a support shaft 507, a first connecting rod 503, and a second connecting rod 505. The first connecting rod 503 is bolted to the bottom side of the inclined plate 501. A first sliding shaft 504 is bolted to the inner side of the first connecting rod 503. The second connecting rod 505 is bolted to the top of the mounting ring 204 near the rotating shaft 502. A second sliding shaft 506 is bolted to the second connecting rod 505. The support shaft 507 is rotatably connected to the support. On the frame 101, a rotating plate 508 is bolted to the support shaft 507. Slide grooves 509 are provided at both ends of the rotating plate 508. The first slide shaft 504 and the second slide shaft 506 are movably arranged in the slide grooves 509. The support shaft 507 is positioned on the rotating plate 508 close to the first connecting rod 503. This arrangement makes the inclined plate 501 a force-saving lever, which is beneficial for the installation ring 204 to pry the first connecting rod 503 and the first slide shaft 504 through the rotating plate 508.

[0021] In this embodiment, the conveying mechanism includes a hopper 401, which is located directly below the bottom of the inclined plate 501. The hopper 401 moves up and down with the roller screen mechanism and is always directly below the inclined plate 501, ensuring that the material on the inclined plate 501 can fall into the hopper 401. The bottom discharge end of the hopper 401 is connected to a conveying pipe 402 by bolts, and the conveying pipe 402 is connected to one end of the top of the mounting cylinder 205 by bolts.

[0022] In this embodiment, a slider 403 is bolted to the side of the hopper 401, a guide rod 404 is slidably connected to the slider 403, and a fixing block 405 is bolted to the end of the guide rod 404. The fixing block 405 is bolted to the bracket 101.

[0023] In this embodiment, the sieving mechanism includes two rotating rings 301, which are rotatably connected to the inner side of the mounting ring 204. A screen cylinder 302 is bolted between the two rotating rings 301. A motor 303 is bolted to the mounting cylinder 205. A connecting plate 304 is bolted to the output end of the motor 303. The connecting plate 304 is bolted to the lower rotating ring 301.

[0024] In this embodiment, a feeding plate 206 is bolted to one end of the bottom of the mounting cylinder 205. A collection component can be installed below the feeding plate 206 to collect the refractory material after screening for further processing.

[0025] Working Principle: When the device performs refractory material screening, the motor 303 is turned on. The motor 303 drives the screen cylinder 302 to rotate through the connecting plate 304, conveying the refractory material to be screened to the upper part of the inclined plate 501. The refractory material raw material moves to the other end guided by the inclined plate 501 and falls into the hopper 401 at the bottom of the inclined plate 501. After being conveyed by the hopper 401 and the conveying pipe 402, it enters the screen cylinder 302. During the rotation of the screen cylinder 302, the refractory material is screened. Small particles pass through the screen cylinder 302 and fall from the opening below the mounting cylinder 205 into the bottom shell 102. Large particles pass through the screen cylinder 302 and are discharged from the discharge plate 206 at one end. During the screening process, when the refractory material in the screen cylinder 302 accumulates and becomes too heavy, the mounting ring 204 and the roller screen mechanism together lower. The pressure support block 203 and the elastic telescopic rod 202 are compressed, causing the mounting cylinder 205 and the mounting ring 204 to descend. The mounting ring 204 drives the second sliding shaft 506 to move downward through the second connecting rod 505. The second sliding shaft 506 pries the first sliding shaft 504 upward through the rotating plate 508. The first sliding shaft 504 lifts the bottom end of the inclined plate 501 through the first connecting rod 503, reducing the inclination angle of the inclined plate 501. This temporarily reduces the supply of refractory material to the screen cylinder 302. After the screen cylinder 302 discharges a portion of the refractory material, its overall weight decreases, the elastic telescopic rod 202 resets, and the inclination angle of the inclined plate 501 is restored. The refractory material screening operation is carried out in this way, so that the weight of the refractory material in the screen cylinder 302 is always within a suitable range to achieve the best screening effect.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
