Description

Technical Field

[0001] This utility model relates to the field of roller press production technology, specifically a wear-resistant and pressure-resistant niobium product roller press. Background Technology

[0002] Roller presses, also known as extrusion mills or roller mills, have extremely high crushing efficiency and can completely or partially replace energy-intensive equipment such as ball mills and mineral mills. A roller press typically consists of two opposing, synchronously rotating extrusion rollers: one fixed roller and one movable roller. Metal materials such as tantalum and niobium are fed from above the rollers and continuously drawn into the space between them by the extrusion rollers. Under high pressure, the material layer is compacted and discharged from the bottom of the machine.

[0003] However, niobium plates are quite hard. When niobium is processed by a roller press, the outside of the extrusion roller will usually wear down with use. After the wear reaches a certain level, the entire roller shaft needs to be disassembled for maintenance, which is inconvenient and affects normal production.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a wear-resistant and pressure-resistant niobium product roller press. Utility Model Content

[0005] The purpose of this invention is to provide a wear-resistant and pressure-resistant niobium product roller press to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant and pressure-resistant niobium product roller press, comprising an outer box and protective components. A processing frame is provided inside the outer box, and the protective components for increasing wear resistance and pressure resistance are provided inside the processing frame. Two sets of protective components are provided. Each protective component includes a roller body, a mounting groove, a mounting plate, and a protective cover. The roller body has a mounting groove at its end, and a mounting plate is installed inside the mounting groove. The end of the mounting plate is connected to the protective cover.

[0007] Furthermore, the protective cover is semi-circular in shape, and there are two protective covers symmetrically arranged about the central axis of the roller.

[0008] Furthermore, a mounting buckle is installed on the side of the upper end of the processing frame, and a hydraulic rod is installed on the inner side of the mounting buckle.

[0009] Furthermore, a support frame is installed at the upper end of the outer box, and a feed hopper is installed on the inner side of the support frame.

[0010] Furthermore, a base frame is mounted on the lower end of the processing frame via a rotating shaft, and a connecting plate is provided on the outer side of the base frame.

[0011] Furthermore, four support columns are installed on the outer side of the connecting plate.

[0012] Furthermore, a screening plate is installed inside the feed hopper, and auxiliary components for pre-crushing are installed on both sides above the screening plate.

[0013] Furthermore, the auxiliary component includes a second hydraulic rod and an auxiliary pressure plate, and the output end of the second hydraulic rod is equipped with the auxiliary pressure plate.

[0014] This utility model provides a wear-resistant and pressure-resistant niobium product roller press, which has the following beneficial effects:

[0015] 1. This utility model uses an installation groove for the installation of the mounting plate, i.e. the installation of the protective cover, so that the protective cover can be installed and disassembled without removing the roller body, increasing the convenience of disassembly and assembly. The protective cover uses wear-resistant weld overlay material for the outer protection of the roller body, increasing the wear resistance and pressure resistance during the processing of niobium products, and increasing the service life of the roller body.

[0016] 2. This utility model uses a feeding hopper for feeding niobium product raw materials. The first hydraulic rod controls the distance between the two processing frames by telescopic control, so that the rollers can better crush the raw material blocks when the motors rotate in opposite directions. The second hydraulic rod controls the auxiliary pressure plate by telescopic control. The auxiliary pressure plate pre-crushes the niobium product raw materials to reduce their volume, so as to avoid the difficulty of crushing the rollers due to excessively large raw material blocks. At the same time, it reduces the wear of the outer protective cover. The screening plate prevents excessively large raw material blocks from falling. Attached Figure Description

[0021] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] like Figure 1 As shown, a wear-resistant and pressure-resistant niobium product roller press includes an outer box 1 and a protective assembly 5. A processing frame 2 is provided inside the outer box 1. A mounting buckle 3 is installed on the upper side of the processing frame 2, and a hydraulic rod 4 is installed inside the mounting buckle 3. The hydraulic rod 4 controls the distance between the two processing frames 2 by telescopic control, so that the roller body 501 can better crush the raw material block when rotated in opposite directions by the motor. A support frame 6 is installed at the upper end of the outer box 1, and a feed hopper 7 is installed inside the support frame 6. The feed hopper 7 is used for feeding niobium product raw materials. A base frame 9 is installed at the lower end of the processing frame 2 through a rotating shaft 8, and a connecting plate 10 is provided on the outer side of the base frame 9. Support columns 11 are installed on the outer side of the connecting plate 10, and the number of support columns 11 is four.

[0023] like Figure 2 As shown, the protective component 5, used to increase wear resistance and pressure resistance, is located inside the processing frame 2. Two sets of the protective component 5 are provided. The protective component 5 includes a roller body 501, a mounting groove 502, a mounting plate 503, and a protective cover 504. The roller body 501 has a mounting groove 502 at its end, which is used for mounting the mounting plate 503, i.e., mounting the protective cover 504. The mounting plate 503 is installed inside the mounting groove 502, allowing the protective cover 504 to be installed and removed without disassembling the roller body 501, increasing ease of installation and removal. The end of the mounting plate 503 is connected to the protective cover 504, which is semi-circular in shape. Two protective covers 504 are symmetrically arranged about the central axis of the roller body 501. The protective cover 504 uses wear-resistant weld overlay material for the outer protection of the roller body 501, increasing wear resistance and pressure resistance during niobium product processing and extending the service life of the roller body 501.

[0024] like Figure 3 As shown, a screen plate 12 is installed inside the feed hopper 7, and auxiliary components 13 for pre-crushing are installed on both sides above the screen plate 12. The auxiliary components 13 include a hydraulic rod 1301 and an auxiliary pressure plate 1302. The hydraulic rod 1301 controls the auxiliary pressure plate 1302 by telescoping, and the output end of the hydraulic rod 1301 is equipped with the auxiliary pressure plate 1302. The auxiliary pressure plate 1302 pre-crushes the niobium product raw material to reduce its volume, avoids the difficulty of crushing the roller 501 due to excessively large raw material blocks, and reduces the wear of its external protective cover 504. The screen plate 12 prevents excessively large raw material blocks from falling.

[0025] In summary, this wear-resistant and pressure-resistant niobium product roller press is first based on... Figures 1-3The structure shown allows the protective cover 504 to be installed on the outside of the roller body 501 via the mounting plate 503, thus enveloping the roller body 501. The wear-resistant weld overlay material protective cover 504 increases the wear resistance and pressure resistance of the roller body 501 during niobium product processing, extending its service life. The mounting groove 502 allows the protective cover 504 to be installed and removed without disassembling the roller body 501, increasing ease of installation and removal. During processing, the niobium product raw material is first added to the feed hopper 7, and the raw material blocks are pre-screened on the screening plate 12, allowing larger pieces of raw material to remain on the screening plate 12. Meanwhile, hydraulic rod 1301 controls the auxiliary pressure plate 1302 through telescopic control. The auxiliary pressure plate 1302 pre-crushes the niobium product raw material to reduce its volume, so that the reduced raw material block can be ground inside the roller 501 that falls through the sieve plate 12. This avoids the roller 501 from being difficult to crush due to the raw material block being too large, and at the same time reduces the wear of its outer protective cover 504. During processing, hydraulic rod 4 controls the spacing of the processing frames 2 on both sides through telescopic control, so that the roller 501 can better crush the raw material block when it is rotated in opposite directions by the motor, so that the worn fragments fall down for the subsequent production of niobium products.
