Description

Technical Field

[0001] This utility model relates to the field of fused magnesia production technology, and more specifically, to a double-roller compactor for fused magnesia production. Background Technology

[0002] Fused magnesia is an alkaline refractory material made by melting natural magnesite, lightly calcined magnesia or sintered magnesia in an electric arc furnace. It is made by calcining magnesite, breccia or magnesium hydroxide extracted from seawater at high temperature. In the process of producing fused magnesia, a compaction operation is required.

[0003] Utility model patent CN220555161U discloses a roller compactor for producing fused magnesia, including a base, a housing fixedly connected to the upper surface of the base, columns fixedly connected to both the left and right sides of the upper surface of the base, a top plate fixedly connected to the top of the columns, an mounting plate fixedly connected to the upper end of the front of the inner cavity of the columns, a first servo motor fixedly connected to the upper surface of the mounting plate, a first screw fixedly connected to the output end of the first servo motor, a first slider threadedly connected to the outer surface of the first screw, and a pressure plate fixedly connected to the inner side of the first slider. This patent achieves a good compaction effect through the arrangement of a crossbar, an electric telescopic rod, a motor box, a first gear, a second slider, a second servo motor, a second gear, a second screw, and pressure rollers, solving the problem of poor compaction in existing compactors for producing fused magnesia, which causes the fused magnesia to easily loosen during use and affects practicality. However, the above patent still has the following shortcomings: the compacted shell is fixedly connected to the base, and the compacted fused magnesia is not easy to remove. It is also not easy to carry out continuous compaction. The fused magnesia in the shell needs to be removed before the fused magnesia raw material can be put in again for compaction, which is not very practical. In addition, the pressure plate is fixedly connected between the two first sliders. When the pressure roller squeezes the pressure plate, it is not easy for the pressure plate to compact the fused magnesia downwards. Therefore, we have proposed a double roller compactor for the production of fused magnesia. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a double-roller compactor for the production of fused magnesia.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0007] In a preferred embodiment of this utility model, the lifting mechanism includes two sets of second electric telescopic rods fixedly installed on the bottom surface of the top plate. The bottom ends of the two sets of second electric telescopic rods are respectively fixedly connected to lifting plates. A set of springs is fixedly connected to each of the two lifting plates.

The bottom ends of each set of sliding rods extend to the bottom of the lifting plate and are fixedly connected to a support plate. The pressure plate is fixedly connected between the two support plates.

[0008] As a preferred embodiment of this utility model, the roller extrusion mechanism includes multiple third electric telescopic rods fixedly installed on the bottom surface of the top plate. The bottom ends of the multiple third electric telescopic rods are fixedly connected to a movable box. The inner cavity of the movable box is rotatably connected to a bidirectional lead screw.

[0013] (1) In this utility model, the compaction shell containing fused magnesia in the inner cavity is placed on the bottom plate. The compaction shell is limited by the limiting block. At the same time, the first electric telescopic rod drives the insert to be inserted into the fixing hole on the side of the compaction shell to fix the compaction shell, thus realizing the function of fixing the compaction shell. In addition, the compaction shell can be removed from the bottom plate so that when the fused magnesia in one compaction shell is compacted, the compaction shell can be directly removed from the bottom plate and other compaction shells can be placed on it to compact other fused magnesia raw materials, thus realizing the function of continuous compaction of fused magnesia.

Through the cooperation of the spring, load-bearing block, slide rod and support plate, the pressure plate can also move up and down after being inserted into the compaction shell, so that the pressure roller can squeeze the pressure plate, thereby moving the pressure plate down to compact the fused magnesia in the compaction shell, thus improving the working quality of the roller compactor for fused magnesia production.

The end of the movable box 21 is fixedly installed with a servo motor 24. The output shaft of the servo motor 24 is connected to the end of the bidirectional lead screw 23 through a coupling.

[0029] In this embodiment, the movable seat 25 is limited by the movable cooperation of the movable seat 25 and the sliding column 22, so that the movable seat 25 can only move along the axial direction of the bidirectional lead screw 23. At the same time, the top surface of the movable seat 25 is in contact with the top surface of the inner cavity of the movable box 21, ensuring that the reaction force received by the movable seat 25 is directly transmitted to the movable box 21.

[0030] For details, please refer to Figures 1 to 4 A control panel 28 is fixedly installed on the outside of a column 2.

[0032] For details, please refer to Figure 1 The sides of the compaction shell 8 are provided with handle grooves 10, and the sides of the compaction shell 8 are in contact with the inner side of the limiting block 7.

[0033] In this embodiment, the clamping shell 8 is moved using the handle groove 10, and the inner side of the limiting block 7 is used to limit the clamping shell 8, ensuring the stability of the clamping shell 8 placed on the top of the base plate 1.

[0034] For details, please refer to Figure 1 The outer size of the pressure plate 5 is equal to the inner size of the compaction shell 8.

[0035] In this embodiment, the pressure plate 5 is ensured to be smoothly inserted into the inner cavity of the compaction shell 8, thereby compacting the fused magnesia raw material in the compaction shell 8.

[0036] Working principle: In use, firstly, the fused magnesia raw material is placed into the inner cavity of the compaction shell 8, and the compaction shell 8 is placed on the top surface of the base plate 1. Multiple limiting blocks 7 are used to limit the compaction shell 8. In addition, multiple first electric telescopic rods 12 are activated to drive multiple inserts 13 to move, so that the inserts 13 are inserted into the fixing holes 9 on the side of the compaction shell 8, thereby fixing the compaction shell 8. Then, the second electric telescopic rod 14 is activated to drive the lifting plate 15, spring 16, load-bearing block 17, and sliding rod 18. The support plate 19 and pressure plate 5 move downwards, so that the bottom end of pressure plate 5 is inserted into the inner cavity of the compaction shell 8. The second electric telescopic rod 14 applies a certain pressure downwards to the lifting plate 15. The spring 16, the load-bearing block 17, the slide rod 18, and the support plate 19 apply a certain pressure to the pressure plate 5, and the spring 16 is compressed by the reaction force. Then, the third electric telescopic rod 20 is activated to drive the moving box 21, the moving seat 25, the U-shaped frame 26, and the pressure roller 27 to move downwards, so that the bottom surface of the pressure roller 27 contacts the top surface of the pressure plate 5, and the pressure roller 27 presses the pressure plate 5 downwards. In addition, the servo motor 24 is activated to drive the bidirectional lead screw 23 to rotate intermittently. The threaded engagement between the bidirectional lead screw 23 and the two moving seats 25 drives the moving seat 25, the U-shaped frame 26, and the pressure roller 27 to move. The pressure roller 27 evenly presses the top of the pressure plate 5 to ensure that the pressure plate 5 can compact the fused magnesia raw material in the compaction shell 8. Finally, after compaction, the third... The electric telescopic rod 20 drives the movable box 21, movable seat 25, U-shaped frame 26 and pressure roller 27 to move upward and reset. The second electric telescopic rod 14 is activated to drive the lifting plate 15, support plate 19 and pressure plate 5 to move upward and reset. At this time, the first electric telescopic rod 12 is activated to drive the insert 13 to disengage from the fixing hole 9 on the side of the compaction shell 8, thereby releasing the fixation of the compaction shell 8. The compaction shell 8 can then be removed from the base plate 1 so that other compaction shells 8 can be placed on it to compact other fused magnesia raw materials.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
