Abstract
Description
Technical Field
[0001] This utility model relates to the field of refractory material production technology, and in particular to a drum screen for refractory material production. Background Technology
[0002] Refractory materials refer to inorganic non-metallic materials that maintain stable physicochemical properties under high-temperature environments (generally exceeding 1580℃) and possess resistance to high temperatures, erosion, scouring, and heavy loads. In the production of granular refractory materials, drum screens are used to separate particles of different sizes. During the actual screening process, some particles clog the screening holes of the drum screen. Existing drum screens have poor self-cleaning capabilities, requiring manual cleaning periodically, which is inconvenient. Therefore, there is an urgent need to develop a drum screen for refractory material production that facilitates screening and prevents clogging through a combination of brush cleaning and vibration, overcoming current shortcomings and meeting current needs. Utility Model Content
[0003] The purpose of this invention is to provide a drum screen for refractory material production to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A rotary drum screen for refractory material production includes a support frame, a screening cylinder, a receiving box, a drive mechanism, a roller brush unclogging mechanism, and striking balls. The screening cylinder is rotatably connected to the support frame and has screening holes. One end of the screening cylinder is open and the other end is closed. An end cap is detachably connected to the open end of the screening cylinder via threads. A rotating shaft is fixed to the closed end of the screening cylinder. The drive mechanism is mounted on the support frame and is used to drive the rotating shaft and the screening cylinder to rotate. The roller brush unclogging mechanism is installed inside the support frame and is used to clean the screening holes on the screening cylinder. There are multiple striking balls. The upper end of each striking ball is fixed to the support frame via a suspension rope. Under the action of gravity and the tension of the suspension rope, the striking balls adhere to the outer surface of the screening cylinder. Multiple protruding ribs for pushing the striking balls are fixed to the outer side of the screening cylinder. The roller brush unclogging mechanism includes a second motor and a brush roller. The second motor is fixed to the support frame, and the brush roller is rotatably connected to the support frame. The output shaft of the second motor is fixed to the brush roller via a coupling.
[0006] Preferably, the head of the raised rib is arc-shaped.
[0007] Preferably, the driving mechanism includes a first motor, a driving wheel, a driven wheel, and a transmission belt. The first motor is fixed on a bracket, and the driving wheel is fixed on the output shaft of the first motor. The driving wheel is connected to the driven wheel via the transmission belt, and the driven wheel is fixed on a rotating shaft.
[0008] Preferably, a receiving box is placed on the ground below the screening cylinder.
[0009] Preferably, a PLC controller is mounted on the bracket, and the first motor and the second motor are electrically connected to the PLC controller respectively.
[0010] The beneficial effects of this utility model are as follows: When using this refractory material production drum screen, the refractory material is placed into the screening drum and the end cover is closed. Then, a first motor drives the drive wheel and driven wheel to rotate, which in turn drives the rotating shaft and screening drum to rotate. The rotation of the screening drum causes the material inside to rotate and be screened. Qualified material passes through the screening drum and falls into the collection box for collection, while unqualified material remains in the screening drum. Simultaneously, a second motor drives the brush roller to rotate, and as the brush roller rotates, its bristles move from the screening drum... The outer side of the brush pushes the material blocking the screening holes of the screening cylinder into the inner part of the cylinder, preventing clogging. Additionally, when the screening cylinder rotates, it drives multiple raised ribs to rotate as well. When these ribs reach the striking ball, they push the ball outwards, separating it from the outer wall of the screening cylinder. After the raised ribs rotate, the striking ball, under the influence of gravity and the tension of the suspension rope, impacts the screening cylinder, causing it to vibrate. This vibration dislodges the material blocking the screening holes, preventing further blockage. In summary, this invention facilitates the screening of refractory materials and prevents clogging of the screening holes through a combination of brush cleaning and vibration.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0020] Specific implementation examples are given below.
[0021] See Figures 1-6 In this embodiment of the present invention, a rotary drum screen for refractory material production includes a support 1, a screening cylinder 2, a receiving box 3, a drive mechanism 4, a roller brush unclogging mechanism 5, and a striking ball 6. The support 1 is fixed to the ground, and the screening cylinder 2 is rotatably connected to the support 1. The screening cylinder 2 is used to screen refractory materials. The screening cylinder 2 is provided with screening holes. One end of the screening cylinder 2 is open and the other end is closed. An end cap 201 is detachably connected to the outside of the open end of the screening cylinder 2 by a thread. A rotating shaft 202 is fixed to the closed end of the screening cylinder 2. The drive mechanism 4 is mounted on the support 1 and is used to drive the rotating shaft 202. The shaft 202 and the screening cylinder 2 rotate. The roller brush cleaning mechanism 5 is installed in the bracket 1 and is used to clean the screening holes on the screening cylinder 2. There are multiple striking balls 6. The upper end of the striking balls 6 is fixed to the bracket 1 by the suspension rope 601. The striking balls 6 are attached to the outer surface of the screening cylinder 2 under the action of gravity and the tension of the suspension rope 601. Multiple protruding ribs 203 for pushing the striking balls 6 are fixed on the outer side of the screening cylinder 2. The head of the protruding ribs 203 is arc-shaped so that the protruding ribs 203 and the striking balls 6 can slide relative to each other. A collection box 3 is placed on the ground below the screening cylinder 2.
[0022] The driving mechanism 4 includes a first motor 401, a driving wheel 402, a driven wheel 403, and a transmission belt 404. The first motor 401 is fixed on the bracket 1. The driving wheel 402 is fixed on the output shaft of the first motor 401. The driving wheel 402 is connected to the driven wheel 403 via the transmission belt 404. The driven wheel 403 is fixed on the rotating shaft 202. In use, the first motor 401 drives the driving wheel 402 and the driven wheel 403 to rotate. The driven wheel 403 drives the rotating shaft 202 and the screening cylinder 2 to rotate. The rotation of the screening cylinder 2 drives the material inside to rotate and be screened.
[0023] The roller brush unclogging mechanism 5 includes a second motor 501 and a brush roller 502. The second motor 501 is fixed on the bracket 1, and the brush roller 502 is rotatably connected to the bracket 1. The output shaft of the second motor 501 is fixed to the brush roller 502 through a coupling. In use, the second motor 501 drives the brush roller 502 to rotate. When the brush roller 502 rotates, its bristles push the blockage in the screening holes of the screening cylinder 2 from the outside of the screening cylinder 2 into the screening cylinder 2, preventing the screening holes of the screening cylinder 2 from becoming blocked.
[0024] A PLC controller 7 is mounted on the bracket 1. The first motor 401 and the second motor 501 are electrically connected to the PLC controller 7 for control purposes.
[0025] Working principle: This refractory material production drum screen works by placing the refractory material into the screening cylinder 2 and covering it with the end cover 201. Then, the first motor 401 drives the drive wheel 402 and driven wheel 403 to rotate. The driven wheel 403 drives the rotating shaft 202 and the screening cylinder 2 to rotate. The rotation of the screening cylinder 2 causes the material inside to rotate and be screened. Qualified material passes through the screening cylinder 2 and falls into the collection box 3 for collection. Unqualified material remains in the screening cylinder 2. At the same time, the second motor 501 drives the brush roller 502 to rotate. When the brush roller 502 rotates, its bristles pass through the screening cylinder. The outer side of the cylinder 2 pushes the material blocking the screening holes of the screening cylinder 2 into the screening cylinder 2, preventing the screening holes of the screening cylinder 2 from becoming blocked. In addition, when the screening cylinder 2 rotates, it drives multiple raised ribs 203 to rotate. When the raised ribs 203 rotate to the striking ball 6, they will push the striking ball 6 outward to separate it from the outer wall of the screening cylinder 2. After the raised ribs 203 rotate, the striking ball 6 will hit the screening cylinder 2 under the action of gravity and the tension of the suspension rope 601, thereby causing the screening cylinder 2 to vibrate. Through the vibration, the material blocking the screening holes of the screening cylinder 2 will fall off, preventing blockage.
[0026] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
