Description

Technical Field

[0001] This utility model relates to the field of blast furnace refractory lining testing and feeding technology, specifically a blast furnace refractory lining testing and feeding device. Background Technology

[0002] Blast furnace refractory lining testing and feeding refers to the process of testing refractory linings during blast furnace construction, overhaul, lining repair, or routine maintenance to verify their performance stability, construction quality, and compatibility. This testing is conducted according to preset process parameters and standards. The feeding process involves transporting the lining to be tested to the testing equipment. Existing feeding devices for lining testing require the lining to be fed to the testing equipment, tested, and then unloaded before reloading from the original location. This transfer process wastes time and reduces operational efficiency. Therefore, a new blast furnace refractory lining testing and feeding device is needed to address these shortcomings and improve efficiency. Utility Model Content

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.

[0015] To make the objectives, technical solutions and advantages of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Please see Figure 1-4 As shown, this utility model is a blast furnace refractory lining testing and feeding device, comprising: The feeding mechanism includes a rotary motor 13 and a feeding disc 14. The output end of the rotary motor 13 is threadedly connected to the middle of the feeding disc 14. Multiple material placement slots 15 are equidistantly opened on the upper outer edge of the feeding disc 14. Multiple slot frames 16 are fixed on the lower outer edge of the feeding disc 14. The inclined slots opened in the upper end of the slot frames 16 are connected to the material placement slots 15. An opening is opened at one end of the material placement slot 15. An electric push rod is fixed in the opening. Two torsion springs 17 are symmetrically fixed on the upper part of the inner wall of the inclined slot. A limit plate 18 is fixed between the two torsion springs 17. The rotating motor 13 receives the feeding tray 14 and provides the power required for rotation, enabling multi-angle adjustment. The feeding tray 14, together with the material placement trough 15, satisfies the material placement and feeding of multiple linings. The opening is connected to the electric push rod, and the feeding process is completed by pushing the electric push rod. The trough frame 16 is connected to the limiting plate 18 via the upper inclined trough and the torsion spring 17, and the limiting plate 18 satisfies the positioning of the lining during material placement.

[0017] A positioning ring 12 is fixed to the bottom of the rotating motor 13, and multiple positioning bolts are equidistantly connected through the middle of the positioning ring 12. The positioning bolts fix the positioning ring 12, and the fixed positioning ring 12 completes the installation and fixation of the rotating motor 13.

[0018] The feeding mechanism also includes a base 11, which is located directly below the rotating disk, and the center of the front of the base 11 is provided with a through cavity. The base 11 provides structural installation and a stable environment.

[0019] In the initial state, the upper part of the limiting plate 18 of the torsion spring 17 extends out of the limiting groove, and the front end of the limiting plate 18 is level with the inclined groove, while the rear end is in contact with the inner wall of the inclined groove. With the help of the elastic force of the torsion spring 17, the angle of the limiting plate 18 can be adjusted, which facilitates the positioning of the inner lining and meets the normal feeding requirements.

[0020] Working principle: The feeding tray 14, together with multiple material placement slots 15, is used to place multiple liners to be tested. At this time, the feeding tray 14 is rotated by the rotating motor 13 so that one of the material placement slots 15 is positioned directly opposite the feed inlet of the testing equipment. Then, the controlled electric push rod acts on the liner in the material placement slot 15 and on the upper part of the limiting plate 18. With the help of the torsion spring 17, the liner is deformed, so that the upper part of the limiting plate 18 extends into the inclined slot, allowing the liner to be smoothly moved out of the material placement slot 15. During the testing of the liner, the rotating motor 13 continues to rotate the feeding tray 14 to replace the positions of the material placement slots 15, and the liner can be put back into the unloaded material placement slot 15.

[0021] This solution reduces the time spent on transportation, ensures continuous testing, significantly improves effectiveness and efficiency, and utilizes the movable connection limit plate 18 to ensure the stability of the inner lining structure during material placement while meeting the requirements for material feeding and pushing.

[0022] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment: It also includes an installation mechanism, which includes a guide groove 21 and a guide block 22. The guide groove 21 is symmetrically opened on both sides of the bottom end inside the cavity. The guide block 22 is slidably connected in the guide groove 21, and the upper end of the guide block 22 is fixed with an installation block 23. Multiple positioning bolts extend to the upper end of the installation block 23. The guide block 22 is fixed to the mounting block 23. The mounting block 23 is used to fix the rotating motor 13. By sliding in the guide groove 21, the rotating motor 13 can be easily moved out of the cavity, realizing external inspection and disassembly.

[0023] The mounting mechanism also includes a movable shaft 26, which is connected through the upper part of the front of the base 11, and a movable plate 27 is sleeved in the middle of the movable shaft 26. The movable shaft 26 is connected to the movable plate 27 and is located at the upper part of the movable plate 27. With the help of the movable action, the movable plate 27 can be adjusted at multiple angles to facilitate the rotation of the motor 13 into and out of the cavity.

[0024] The mounting mechanism also includes a sealing plate 24, which is located at the lower part of the front of the base 11. The outer edge of the sealing plate 24 is in contact with the inner wall of the cavity. The upper end of the sealing plate 24 is attached to the bottom end of the movable plate 27. The sealing plate 24 is fixed to the front of the mounting block 23 by two connecting posts 25 fixed at the inner end. The sealing plate 24 seals the lower front part of the cavity and ensures the stability of the structure by abutting against the inner wall of the cavity. The connecting column 25 is used for connecting and installing the sealing plate 24 and the mounting block 23.

[0025] Working principle: When overhauling the rotating motor 13, the sealing plate 24 is opened beforehand. The guide block 22 slides outward in the guide groove 21, moving the rotating motor 13 out of the cavity. During the outward movement of the rotating motor 13, it acts on the movable plate 27, causing the movable plate 27 to change angle to unfold and ensure that the rotating motor 13 moves outward smoothly. After the overhaul of the rotating motor 13 is completed, the above reverse operation steps are applied.

[0026] This solution allows for the direct removal and installation of the rotating motor 13 by pulling the sealing plate 24, eliminating the need for secondary operations. It is simple, convenient, and further enhances the performance. Moreover, it eliminates the need to disassemble the entire sealing structure, saving time and effort while meeting the requirements.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
