Description

Technical Field

[0001] The utility model relates to the technical field of submerged arc furnace equipment, and particularly relates to a material conveying device for a submerged arc furnace. Background Art

[0002] A submerged arc furnace is also called an electric arc furnace or a resistance furnace. It is mainly used for reducing and smelting ores, carbonaceous reducing agents and solvents and other raw materials, and mainly produces ferroalloys such as ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, and silicomanganese alloy, which are important industrial raw materials in the metallurgical industry and chemical raw materials such as calcium carbide. The load of the submerged arc furnace transformer is continuous and stable, the impedance voltage is low, the number of voltage regulation levels is large, the step difference is small, and the overload capacity is strong. It can be divided into two types: on-load and non-excitation voltage regulation. Generally, the first few levels output at a constant capacity, and the last few levels output at a constant current. During the material conveying process of the submerged arc furnace, due to the high-speed falling and impact of the materials, the feeding equipment often faces the risk of damage.

Compared with the prior art, the utility model has the advantages of simple structure, convenient operation, and can effectively avoid the damage of the feeding equipment.

[0004] In the existing material conveying device for a submerged arc furnace, a large amount of materials continuously impact and rub against the buffer net during the material conveying process, which is easy to cause wear and damage to the buffer net. At the same time, the buffer filler bears huge pressure and impact for a long time, and its performance will gradually decline, and it needs to be maintained and replaced frequently, resulting in a reduction in production efficiency. Therefore, there is a problem that the buffer mechanism needs to be maintained frequently. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide a material conveying device for a submerged arc furnace, which can effectively solve the problems put forward in the background art.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A material conveying device for a submerged arc furnace includes a blanking pipe, an inlet, and a feeding trough. The upper surface of the blanking pipe is provided with an inlet, and the outer surface of the blanking pipe is fixedly connected with a feeding trough.

Detailed Description of the Preferred Embodiments

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] As Figure 1 - Figure 4 shown, a material conveying device for a submerged arc furnace includes a blanking pipe 1, a feed inlet 2 and a material conveying trough 3. The upper surface of the blanking pipe 1 is provided with a feed inlet 2, and the outer surface of the blanking pipe 1 is fixedly connected with a material conveying trough 3. The outer surface of the blanking pipe 1 is fixedly connected with a dust suction mechanism 4, and the inner wall of the blanking pipe 1 is slidably connected with a buffer mechanism 5.

[0025] In order to reduce the maintenance frequency of the buffer mechanism 5, the buffer mechanism 5 includes a buffer plate 501 slidably connected to the inner wall of the blanking pipe 1. A connecting column 508 is fixedly connected to the lower surface of the buffer plate 501. A connecting plate 507 is fixedly connected to the lower surface of the connecting column 508. A damping rod 504 and a spring 503 are fixedly connected to the lower surface of the connecting plate 507. The lower ends of the damping rod 504 and the spring 503 are fixedly connected to a sliding plate 502. Multiple through holes are formed in the outer surface of the buffer plate 501. A fixing plate 506 is fixedly connected to the inner wall of the blanking pipe 1. Multiple cleaning rods are fixedly connected to the outer surface of the fixing plate 506 in cooperation with the outer surface of the buffer plate 501. The through holes on the outer surface of the buffer plate 501 can be conveniently cleaned through the fixing plate 506. A bolt 505 is threadedly connected to the outer surface of the blanking pipe 1. The upper end of the bolt 505 is rotatably connected to the lower surface of the sliding plate 502. The outer surface of the sliding plate 502 is slidably connected to the inner wall of the blanking pipe 1. By rotating the bolt 505, the tightness of the spring 503 and the damping rod 504 can be conveniently adjusted.

[0026] It is worth mentioning that after the material falls from the feed inlet 2, the material drops onto the upper surface of the buffer plate 501. The buffer plate 501 moves downward under the impact. The downward movement of the buffer plate 501 drives the connecting column 508 and the connecting plate 507 to move downward. The downward movement of the connecting plate 507 causes the spring 503 and the damping rod 504 to deform, thereby facilitating the buffering of the material falling on the upper surface of the buffer plate 501 and reducing the maintenance frequency of the buffer mechanism 5.

[0027] In order to filter the debris in the blanking pipe 1, the dust suction mechanism 4 includes a fixed frame 404 fixedly connected to the outer surface of the blanking pipe 1. A second filter plate 406 and a first filter plate 405 are fixedly connected to the inner wall of the fixed frame 404. A suction fan 401 is fixedly connected to the outer surface of the fixed frame 404. The aperture of the second filter plate 406 is larger than that of the first filter plate 405. The outer surface of the second filter plate 406 is slidably connected to the outer surface of the buffer plate 501. The second filter plate 406 facilitates the screening of debris and thus the filtration of raw materials. A dust collection bin 402 is fixedly connected to the lower surface of the fixed frame 404. A second filter plate 406 is fixedly connected to the outer surface of the dust collection bin 402. The second filter plate 406 facilitates the observation of the debris in the dust collection bin 402 and thus the timely recovery of the debris in the dust collection bin 402. A sliding plate 403 is slidably connected to the inner wall of the dust collection bin 402. The outer surface of the sliding plate 403 is fixedly connected to the outer surface of the dust collection bin 402 by screws. By sliding the sliding plate 403, the debris in the dust collection bin 402 can be conveniently cleaned.

[0028] It is worth mentioning that when the suction fan 401 is started, the suction fan 401 extracts the gas inside the fixed frame 404, thereby facilitating the formation of an air flow on the inner wall of the fixed frame 404, enabling the air flow to carry debris through the second filter plate 406 and move into the first filter plate 405. Then, it is convenient to block the debris through the first filter plate 405, causing the debris to fall on the outer surface of the sliding plate 403. It is convenient to observe the debris in the dust collection bin 402 through the second filter plate 406. Then, the sliding plate 403 and the dust collection bin 402 are separated to facilitate the cleaning of the debris in the dust collection bin 402.

[0029] Working principle: After the material falls from the feed port 2, the material lands on the upper surface of the buffer plate 501. The buffer plate 501 moves downward under the impact. The downward movement of the buffer plate 501 drives the connecting column 508 and the connecting plate 507 to move downward. The downward movement of the connecting plate 507 causes the springs 503 and the damping rods 504 to deform, thereby facilitating the buffering of the material falling on the upper surface of the buffer plate 501, enabling the material to slide onto the outer surface of the feeding chute 3, and thus facilitating the feeding of the submerged arc furnace. By rotating the bolt 505, on the one hand, it is convenient to adjust the tightness of the springs 503 and the damping rods 504, and on the other hand, the cleaning rod on the upper surface of the fixed plate 506 is inserted into the through hole on the outer surface of the buffer plate 501 to facilitate the cleaning of the outer surface of the buffer plate 501. At the same time, the suction fan 401 is started. The suction fan 401 extracts the gas inside the fixed frame 404, thereby facilitating the formation of an air flow on the inner wall of the fixed frame 404, enabling the air flow to carry debris through the second filter plate 406 and move into the first filter plate 405. Then, it is convenient to block the debris through the first filter plate 405, causing the debris to fall on the outer surface of the sliding plate 403. It is convenient to observe the debris in the dust collection bin 402 through the second filter plate 406. Then, the sliding plate 403 and the dust collection bin 402 are separated to facilitate the cleaning and recycling of the debris in the dust collection bin 402.
