Description

Technical Field

[0001] This utility model relates to the field of drum screen technology, specifically a replaceable drum screen. Background Technology

[0002] A rotary drum screen is a mechanical device used for screening and grading materials, widely used in industries such as mining, building materials, and chemicals. A rotary drum screen mainly consists of a motor, reducer, drum assembly, frame, and sealing cover. The drum assembly, which houses the screen mesh, is the core component for achieving the screening function. Common materials for the screen mesh include stainless steel, polyurethane, high manganese steel, nylon, and rubber, and the selection depends on different working conditions. In existing technologies, conventional rotary drum screen assemblies have a one-piece structure for the screen mesh and drum. If a different screen mesh is needed, the entire drum needs to be replaced. Furthermore, the screen mesh can become clogged or even damaged during use, and because the screen mesh and drum are a single unit, replacing the screen mesh is very cumbersome. Summary of the Invention

[0003] This utility model aims to address the technical deficiencies of existing technologies by providing a replaceable drum screen, thereby solving the technical problem that the current drum screen and drum are an integral structure, making it inconvenient to replace the screen separately.

[0004] To achieve the above technical objectives, the present invention adopts the following technical solution:

[0005] A replaceable drum screen includes a main shaft, support discs, spokes, connecting rods, support rings, protrusions, mesh material, clamps, slotted holes, and bolts. Two support discs perpendicular to the main shaft axis are fixedly connected to the cylindrical surface of the main shaft, and the support discs are coaxial with the main shaft. Several spokes extending radially along the main shaft are fixedly connected to the cylindrical surface of the main shaft. The spokes are divided into several groups, with each spoke in each group located in the same circular plane. Several connecting rods parallel to the main shaft axis are fixedly connected between the ends of each group of spokes. Support rings are fixedly connected between the ends of each group of spokes. Two support discs abut against the outer sides of two groups of spokes located at both ends. Several protrusions are provided on the support rings, and mesh material is attached to the outside of each support ring, with the protrusions penetrating the mesh material. Several slotted holes are provided on the clamps, which hug the support rings. The protrusions are inserted into the slotted holes, and the ends of the clamps are secured by bolts, thus pressing and fixing the mesh material.

[0006] Preferably, the mesh material is stainless steel, polyurethane, high manganese steel, nylon, or rubber.

[0007] Preferably, the support ring is a ring-shaped sheet.

[0008] Preferably, the connecting rod is a rod-shaped or tubular object.

[0009] Preferably, the end of the clamp is fastened by bolts, including: protrusions on both sides of the clamp's port, with bolts passing through the two protrusions and fastened to nuts.

[0010] Preferably, the end of the protrusion has a pointed cone.

[0011] In the above technical solution, the main shaft is used to connect with the geared motor to drive the rotation of this utility model; the support plate abuts against the spokes on the outer side from both sides, playing a role in reinforcement and restriction; the spokes are used to form an inner support plane and to set the connecting rod and support ring, thereby forming a skeleton support structure; the support ring is not only part of the above skeleton support structure, but also used to set protrusions, and as attachment points for the mesh material and force points for the clamp; the protrusions are used to penetrate the mesh material attached to the support ring, thereby playing a role in temporarily fixing and positioning the mesh material before loading the clamp, and on the other hand, the protrusions are used to insert into the strip hole on the clamp when loading the clamp, playing a role in positioning the clamp during the loading process; the mesh material is used to screen the material, and it is a conventional material; the clamp is used to clamp onto the support ring, thereby playing a role in pressing and fixing the mesh material between it and the support ring; the bolts are used to fasten the clamp.

[0012] This invention provides a replaceable drum screen. The technical solution constructs a skeleton support structure with support rings. The support rings have evenly distributed protrusions on their outer sides, serving as attachment points for the mesh material. A clamp with slotted holes is then used to hold the mesh material onto the support rings, thereby pressing and fixing the mesh material. This invention allows for flexible replacement of the mesh material and the drum skeleton, and is simple to operate and highly efficient. Attached Figure Description
