Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotary drum screen technology, and in particular to a rotary drum screen that is easy to disassemble and clean. Background Technology
[0002] In many industries such as agricultural production, ore processing, and building material processing, the roller screen is a commonly used screening equipment. With its continuous operation and large processing capacity, it is widely used for material grading and screening.
[0003] However, traditional drum screens have a simple structure and cannot perform screening quickly and evenly, resulting in poor screening effect. In addition, traditional drum screens are fixed by welding. Although welding ensures the structural stability of the equipment during operation, the drum screen is difficult to disassemble and clean after screening, which increases the cleaning and maintenance time. Therefore, we have introduced a drum screen that is easy to disassemble and clean. Utility Model Content
[0004] The main purpose of this invention is to provide a drum screen that is easy to disassemble and clean, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A roller screen that is easy to disassemble and clean includes a first fixed plate and a second fixed plate. Two support rods are fixedly connected to the lower ends of the first fixed plate and the lower ends of the second fixed plate. A U-shaped plate is fixedly connected to the left end of the first fixed plate. A rotating device is inserted and installed on the left end of the U-shaped plate. A screening component is fixedly connected to the right side of the outer surface of the rotating device.
[0007] Preferably, the rotating device includes a servo motor and a driven transmission wheel. The output end of the servo motor is fixedly mounted with a driving transmission wheel. The outer surfaces of the driving transmission wheel and the driven transmission wheel are connected by a transmission belt. The right end of the driven transmission wheel is fixedly connected with a fixing component. The right end of the servo motor is fixedly connected to the left end of the U-shaped plate. The output end of the servo motor passes through the left end of the U-shaped plate and extends into the U-shaped plate.
[0008] By adopting the above technical solution: the output of the servo motor directly drives the active transmission wheel, which in turn drives the driven transmission wheel through the transmission belt. The power is quickly transmitted to the fixed components and the drum screen body, so that the drum screen body rotates stably and the material screening process is accelerated.
[0009] Preferably, the right end of the drive drive wheel is movably connected to the right inner wall of the U-shaped plate via a bearing.
[0010] By adopting the above technical solution, the right end of the drive wheel is connected to the right inner wall of the U-shaped plate through a bearing, forming a stable support structure.
[0011] Preferably, the fixing component includes a transmission roller, and a plurality of fixing rods are fixedly connected to the outer surface of the transmission roller. An arc-shaped plate is fixedly connected to one end of each fixing rod away from the center of the transmission roller. The left end of the transmission roller is fixedly connected to the right end of the driven transmission wheel.
[0012] By adopting the above technical solution, the transmission roller is fixedly connected to the driven transmission wheel, and the power is evenly transmitted to the arc plate through several fixed rods, forming a rigid transmission structure.
[0013] Preferably, the screening component includes a first fixing ring and a second fixing ring, and a roller screen body is movably sleeved inside the first fixing ring and the second fixing ring. The outer surface of the roller screen body has a plurality of screening holes that pass through both inside and outside. The outer surface of the first fixing ring is fixedly connected to the upper end of the first fixing plate, and the outer surface of the second fixing ring is fixedly connected to the upper end of the second fixing plate.
[0014] By adopting the above technical solution: the main body of the roller screen is movably sleeved in the first and second fixed rings, and then fixed to the driven transmission wheel by bolts. During cleaning and maintenance, the screen body can be easily removed from the fixed rings simply by unscrewing the bolts. Compared with the traditional welded or one-piece molded structure, the disassembly and assembly time is shortened.
[0015] Preferably, a plurality of the screening holes are arranged in a circular array around the center of the roller screen body, and the roller screen body is inclined to the upper left and lower right.
[0016] By adopting the above technical solution, the screening holes distributed in a ring array combined with the inclined roller screen body optimizes the material flow path. When the roller screen body rotates, the material is less likely to accumulate at the screening holes. Moreover, under the action of gravity, the material stuck in the screen holes is more likely to be washed off by subsequent materials or slide off on its own, effectively reducing screen hole blockage and ensuring the long-term stable operation of the roller screen.
[0017] Preferably, the outer surfaces of several of the arc-shaped plates are fixedly connected to the inner wall surface of the roller screen body.
[0018] By adopting the above technical solution, the outer surface of the arc plate is fixedly connected to the inner wall of the drum screen body, so that the power of the driven transmission wheel can be directly and efficiently transmitted to the drum screen body.
[0019] Compared with the prior art, the present invention has the following beneficial effects:
[0020] 1. In this utility model, the servo motor is started, and its output end drives the active transmission wheel to rotate. The power is transmitted to the driven transmission wheel through the transmission belt, which in turn drives the fixed component and the rotund screen body to rotate stably. After the material to be screened is poured into the upper left side of the rotund screen body, it moves downward along the inner wall of the inclined rotund screen body under the dual action of gravity and centrifugal force. During this process, the material that meets the size of the screening hole passes through the screening hole under the combined action of multiple forces and is screened. The material that does not meet the size is discharged from the discharge port on the lower right side, so that the material can be screened quickly and evenly in the rotund screen, with high screening efficiency and stable screening effect.
[0021] 2. In this utility model, after the screening operation is completed, the drum screen body is movably connected to the first and second fixing rings. No complicated tools are required for disassembly. The drum screen body can be directly removed after removing the bolts. For a small amount of residual material on the surface of the drum screen body, it can be cleaned directly from the outside with a brush or broom. If deep cleaning is required, the removed drum screen body can be easily cleaned from all directions. Whether it is residual material inside or impurities clogging the screen holes, it can be easily cleaned. This easy-to-disassemble structural design shortens the cleaning and maintenance time compared with the traditional drum screen and improves the efficiency of equipment use.

[0030] Please see Figure 1-4 This utility model provides a technical solution:
[0031] A roller screen that is easy to disassemble and clean includes a first fixed plate 1 and a second fixed plate 2. Two support rods 3 are fixedly connected to the lower ends of the first fixed plate 1 and the second fixed plate 2. A U-shaped plate 4 is fixedly connected to the left end of the first fixed plate 1. A rotating device 5 is inserted and installed on the left end of the U-shaped plate 4. A screening component 6 is fixedly connected to the right side of the outer surface of the rotating device 5.
[0032] In this embodiment, the rotating device 5 includes a servo motor 51 and a driven transmission wheel 52. A driving transmission wheel 53 is fixedly mounted on the output end of the servo motor 51. A transmission belt 54 is connected to the outer surfaces of the driving transmission wheel 53 and the driven transmission wheel 52. A fixing component 55 is fixedly connected to the right end of the driven transmission wheel 52. The right end of the servo motor 51 is fixedly connected to the left end of the U-shaped plate 4. The output end of the servo motor 51 passes through the left end of the U-shaped plate 4 and extends into the U-shaped plate 4. The right end of the driving transmission wheel 53 is movably connected to the right inner wall of the U-shaped plate 4 via a bearing. The fixing component 55 includes a transmission roller 551. Several fixing rods 552 are fixedly connected to the outer surface of the transmission roller 551, with the fixing rods 552 located away from the center of the transmission roller 551. One end of each component is fixedly connected to an arc-shaped plate 553, and the left end of the transmission roller 551 is fixedly connected to the right end of the driven transmission wheel 52; the screening assembly 6 includes a first fixed ring 61 and a second fixed ring 62, and a roller screen body 63 is movably sleeved in the first fixed ring 61 and the second fixed ring 62. The outer surface of the roller screen body 63 has several screening holes 64 that pass through it. The outer surface of the first fixed ring 61 is fixedly connected to the upper end of the first fixed plate 1, and the outer surface of the second fixed ring 62 is fixedly connected to the upper end of the second fixed plate 2; the several screening holes 64 are arranged in a circular array around the center of the roller screen body 63, and the roller screen body 63 is inclined to the upper left and lower right; the outer surfaces of the several arc-shaped plates 553 are all fixedly connected to the inner wall surface of the roller screen body 63.
[0033] It should be noted that this utility model is an easy-to-disassemble and clean roller screen. During installation, the roller screen body 63 is fitted into the first fixing ring 61 and the second fixing ring 62, and then fixed to the driven transmission wheel 52 with bolts. During use, the servo motor 51 starts to run after being powered on. Its output end rotates, driving the active transmission wheel 53 fixedly installed thereto to rotate. When the active transmission wheel 53 rotates, it transmits power to the driven transmission wheel 52 through the tensioned transmission belt 54. The rotation of the driven transmission wheel 52 causes the fixed component 55 fixedly connected to its right end to rotate synchronously. Several fixed rods 552 and arc plates 553 fixedly connected to the outer surface of the transmission roller 551 also rotate together. Since the outer surfaces of several arc plates 553 are fixedly connected to the inner wall of the roller screen body 63, the rotation of the arc plates 553 drives the roller screen body 63 to start rotating stably. Holding the material to be screened, at a suitable height on the upper left side of the roller screen body 63, slowly and evenly pour the material into the roller screen body 63. The material enters the rotisserie screen body 63. Because the rotisserie screen body 63 is inclined from left to right, the material slides downward naturally under its own gravity. At the same time, the rotation of the rotisserie screen body 63 generates centrifugal force, which further pushes the material downward along the inner wall. During the process of the material sliding along the inner wall of the rotisserie screen body 63, the material that meets the size of the screening hole 64 falls through the screening hole 64 distributed in a ring array around the center of the rotisserie screen body 63 under the combined action of gravity, centrifugal force and sliding friction, thus completing the screening. The material that does not meet the size cannot pass through the screening hole 64 and continues to slide inside the rotisserie screen body 63 until it is discharged from the discharge port on the lower right side. After all the material to be screened has been processed, the power of the servo motor 51 is turned off, and the rotisserie screen body 63 is allowed to stop rotating completely under the action of inertia. If a small amount of material remains on the surface of the rotisserie screen body 63, a brush or broom is used to clean the surface of the rotisserie screen body 63 from the outside to remove the residual material.

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.
