Description

Technical Field

[0001] This utility model relates to the field of disc ball-forming machine technology, specifically to a rubber liner for a disc ball-forming machine. Background Technology

[0002] In the metallurgical pellet production process, the disc pelletizer is the core equipment for rolling raw materials such as finely ground iron concentrate into pellets. Its bottom liner is in direct contact with the material and must have good wear resistance, impact resistance and flatness to ensure uniform material distribution and pelletizing efficiency.

[0003] In the existing technology, multiple fan-shaped liners are fixed to the bottom plate of the ball plate to form a circular liner structure, and the liner can be disassembled as a whole. However, there is a significant drawback: when a local area of ​​the liner is damaged due to material scouring or impact, the entire fan-shaped liner needs to be disassembled and replaced. It is not possible to treat only the damaged part. This not only leads to the waste of liner material in the undamaged area, but also increases the downtime and labor costs during the replacement process, and reduces the efficiency of equipment operation and maintenance. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rubber liner for a disc ball-making machine, comprising a liner assembly adapted to the bottom plate of the disc ball-making machine; the liner assembly comprises a semi-circular plate, a middle plate, and an outer plate, wherein there are two semi-circular plates, which are spliced ​​into a circle, and the middle plate and the outer plate are both fan-shaped, the middle plate forming a ring around the inner semi-circular plate, and the outer plate forming a ring around the middle plate; the liner assembly is formed by splicing the semi-circular plate, the middle plate, and the outer plate to form a complete circular structure, and each of the semi-circular plate, the middle plate, and the outer plate is provided with multiple column heads, the column heads being integrally formed with the corresponding plate body.

[0005] Furthermore, the semicircular plate, the middle plate, and the outer plate are all connected to the ball plate base plate by bolts.

[0006] Furthermore, the middle plate has twelve pieces, the outer plate has twenty-four pieces, the sector angle of the middle plate is twice that of the outer plate, and the outer arc length of the middle plate is twice that of the inner arc length of the outer plate.

[0007] Furthermore, the semicircular plate, the middle plate, and the outer plate are all made of rubber.

[0008] Furthermore, the column head can be any one of a regular hexagon, a circle, or an ellipse.

[0009] Furthermore, the column head is evenly distributed in multiple concentric circles, with the distance between adjacent concentric circles being the same, and the ends of the column heads are all on the same horizontal plane.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0011] The rubber liner of this disc ball-forming machine uses a segmented splicing structure of semi-circular plates, fan-shaped middle plates, and fan-shaped outer plates. When a section is partially damaged, there is no need to disassemble the entire liner. Only the damaged semi-circular plate, middle plate, or outer plate needs to be removed and replaced individually, which greatly reduces the waste of liner materials, shortens downtime for replacement, and reduces labor maintenance costs.

[0015] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-2 This embodiment of a disc ball-forming machine rubber liner includes a liner assembly adapted to the ball disc bottom plate of the disc ball-forming machine; the liner assembly includes a semi-circular plate 1, a middle plate 2, and an outer plate 3. There are two semi-circular plates 1, which are spliced ​​together to form a circular inner ring structure; the middle plate 2 and the outer plate 3 are both fan-shaped, wherein the middle plate 2 has twelve pieces, which surround the inner ring semi-circular plate 1 to form an annular middle ring structure; the outer plate 3 has twenty-four pieces, which surround the middle ring middle plate 2 to form an annular outer ring structure.

[0017] The semicircular plate 1, the middle plate 2, and the outer plate 3 are all detachably connected to the ball plate base plate of the disc baller by bolts, making them easy to disassemble and replace individually.

[0018] In addition, the semicircular plate 1, the middle plate 2 and the outer plate 3 are all made of rubber, which has good wear resistance and impact resistance; the semicircular plate 1, the middle plate 2 and the outer plate 3 are each provided with multiple column heads 4, and the column heads 4 and the corresponding plate body are integrally formed, which can enhance the friction between the liner and the material and improve the ball-forming effect.

[0019] To further explain, the cross-sectional shape of the column head 4 is any one of regular hexagon, circle or ellipse, preferably regular hexagon; and the column heads 4 are evenly distributed in multiple circles on the corresponding plate, with the same spacing between two adjacent circles of column heads 4, and the heads of all column heads 4 are on the same horizontal plane to ensure the flatness of the liner surface and ensure the uniformity of the material.

[0020] Meanwhile, the fan-shaped angle of the middle plate 2 is twice that of the fan-shaped angle of the outer plate 3, and the outer arc length of the middle plate 2 is twice that of the inner arc length of the outer plate 3, ensuring that there are no obvious gaps after the middle plate 2 and the outer plate 3 are spliced ​​together, forming a complete ring structure.

[0021] The working principle of the above embodiments is as follows:

[0022] First, place the two sets of semicircular plates in the center of the ball plate base and lock them to the ball plate base with bolts to form a circle. Then, distribute multiple middle plates evenly along the outer perimeter of the two sets of semicircular plates that have been spliced ​​into a circle and lock them one by one with bolts. Finally, distribute multiple outer plates evenly along the outer perimeter of the circular structure formed by the middle plates to complete the fixation and ensure that all plates are spliced ​​tightly without obvious gaps.

[0023] When a section, such as a single middle plate, is partially damaged, only the bolts corresponding to that section need to be removed, the damaged section removed, and a new section replaced. There is no need to stop the machine to remove other intact sections, which can shorten the replacement time and avoid material waste.

[0024] The entire workflow is now complete, and anything not described in detail in this specification is existing technology known to those skilled in the art.
