Description

Technical Field

[0001] The utility model relates to the technical field of fine-grain drum screens, in particular to a fine-grain drum screen with a cleaning function. Background Art

[0002] Fine particle drum screen is a device for screening materials. The materials are placed inside the drum screen and screened by the rotation of the drum screen.

[0003] The existing fine particle drum screen has the problem that it is inconvenient to clean the drum screen quickly;

[0004] The reason for this problem is that the drum screen is driven by a motor to rotate the drum screen, and then the material is sent to the inside of the drum screen. The rotation of the drum screen drives the material to move, so that the finer material falls out of the gaps in the drum screen mesh, thereby completing the material screening. After the material is screened, some of the material will be stuck in the gaps inside the screening drum. In order not to affect the next screening of the material, the screening drum needs to be cleaned. Some screening barrels screen smaller particles, the gaps between the screening drums are smaller, and the volume of the screening drum is larger. Most screening barrels are cleaned by manual water spraying. If the screening hole is small, impurities will be stuck inside the screening hole, resulting in the water flow being unable to wash away the impurities inside the screening hole in some positions, which reduces the cleaning effect of the screening drum. It also makes the process of manually cleaning the screening barrel very laborious. Therefore, we propose a fine-grained drum screen with a cleaning function. Utility Model Content

[0030] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0031] The embodiment of the utility model discloses a binding device for file arrangement.

[0032] According to the attached Figure 1-7 As shown, it includes a main frame 1, a drum screen 101 is installed on the outside of the main frame 1, and cleaning mechanisms are provided on both sides of the main frame 1. The cleaning mechanism includes a movable plate 2, which is movably arranged on both sides of the main frame 1, and a cleaning brush plate 201 is installed on the side of the movable plate 2. The movable plate 2 drives the cleaning brush plate 201 to move. The cleaning brush plate 201 is used to clean impurities in the gaps of the drum screen 101. A fixed frame plate 203 is movably arranged on the outside of the movable plate 2, and the fixed frame plate 203 fixes the end of the water pipe.

[0033] The two sides of the movable plate 2 are fixedly connected with the mounting plates 207, the outside of the mounting plate 207 is fixedly connected with the mounting box 202, the outside of the mounting plate 207 is rotatably connected with the threaded rod 210, the threaded rod 210 is rotatably connected to the inside of the mounting box 202, and the end of the threaded rod 210 is fixedly connected with a rotating circular plate 209, which is arranged on the outside of the mounting box 202.

[0034] The outside of the movable plate 2 is fixedly connected to a support plate 214, which is slidably connected to the inside of the mounting box 202. The support plate 214 is threadedly connected to the outside of the threaded rod 210. The two sides of the mounting box 202 are fixedly connected to the outer frame plate 204, which is fixedly connected to the outside of the mounting plate 207. The outside of the mounting plate 207 is fixedly connected to a limiting plate 208, and the end of the limiting plate 208 is fixedly connected to the inner side of the outer frame plate 204.

[0035] The outside of the movable plate 2 is fixedly connected to the auxiliary plate 206, and the auxiliary plate 206 is movably sleeved on the outside of the limit plate 208. The outside of the movable plate 2 is fixedly connected to the functional plate 205, and the inside of the functional plate 205 is slidably connected to the sliding block 211. The functional plate 205 is arranged above the support plate 214, and the top of the sliding block 211 is fixedly connected to the connecting block 212. The fixed frame plate 203 is arranged on the outside of the connecting block 212, and the outside of the connecting block 212 is fixedly connected to the screw rod 213. The outside of the screw rod 213 is movably sleeved with a nut cap, and the outer surface of the nut cap is against the fixed frame plate 203.

[0036] The motor drives the drum screen 101 to rotate, and then the material is sent to the inside of the drum screen 101. The rotation of the drum screen 101 drives the material to move, so that the finer material falls out from the mesh gaps of the drum screen 101, thereby completing the material screening work.

[0037] After the material screening is completed, the excess material inside the drum screen 101 is taken out, and then the round rod outside the rotating circular plate 209 is rotated, so that the round rod drives the rotating circular plate 209 to rotate, and the rotating circular plate 209 will drive the threaded rod 210 to rotate during the rotation process. The threaded rod 210 will rotate inside the installation box 202 at this time, and the threaded rod 210 will also rotate outside the installation plate 207. The threaded rod 210 will drive the support plate 214 to move when it rotates. At this time, the support plate 214 will slide inside the installation box 202. The support plate 214 will drive the movable plate 2 to move during the movement. At this time, the movable plate 2 moves toward the position of the drum screen 101, and the movable plate 2 will drive the auxiliary plate 207 during the movement. 6 slides on the outside of the limit plate 208 until the movable plate 2 drives the bristles of the cleaning brush plate 201 to be against the outside of the drum screen 101, and then starts the rotation of the drum screen 101. By setting the movable plate 2 to drive the cleaning brush plate 201 to move, the cleaning brush plate 201 is moved to the outside of the drum screen 101. During the rotation of the drum screen 101, the bristles on the outside of the cleaning brush plate 201 can brush off the materials blocked inside the screening holes of the drum screen 101, and a large area can be cleaned at one time, which reduces the complexity of personnel cleaning and improves the cleaning efficiency of the screening barrel. At the same time, the cleaning brush plate 201 can be kept away from the outside of the drum screen 101 when not in use, and will not affect the normal use of the drum screen 101.

[0038] The fixed frame plate 203 is fixedly sleeved on the outside of the water spray pipe, and then the fixed frame plate 203 is placed on the outside of the connecting block 212. At this time, the fixed frame plate 203 will be movably sleeved on the outside of the screw rod 213, and then the nut cap is installed on the outside of the screw rod 213. Then, the position of the sliding block 211 is moved to drive the water spray pipe to move, so that the water spray pipe can remain in the same position when spraying water for cleaning in one position, reducing the complexity of manual support. At the same time, if the position of the water spray pipe needs to be moved, it is only necessary to move the position of the sliding block 211. When the water spray pipe is not needed, it is only necessary to remove the nut cap from the outside of the screw rod 213, and then the water spray pipe and the fixed frame plate 203 can be removed.

[0039] In summary, compared with the existing technology, it has the following beneficial effects:

[0040] The cleaning brush plate 201 can be kept away from the outside of the drum screen 101 when not in use, and will not affect the normal use of the drum screen 101.
