Description

Technical Field

[0001] The utility model belongs to the technical field of converter production equipment, and particularly relates to a material feeding device behind a converter furnace. Background Art

[0002] Lining repair of a converter refers to the operation of stopping or not stopping the furnace to repair the suddenly damaged or easily damaged and eroded parts of the converter. The key to implementing this technology lies in using a suitable method to maintain the furnace lining in the shortest possible time without any safety accidents. The existing converter lining repair methods include refractory material repair, refractory brick patching, and scrap steel furnace protection. There are powdered refractory materials and binders in the refractory materials. The refractory materials have a certain fluidity at high temperatures. After steelmaking, the binder in the furnace is melted at high temperatures, and the refractory materials are bonded to the refractory bricks of the converter furnace lining to form a lining repair layer. Refractory brick patching is to patch refractory bricks on the eroded parts of the converter with refractory mud, and this method requires manipulator operation. The addition method of scrap steel furnace protection is manual shoveling or forklift tipping, so as to add scrap steel into the furnace.

[0003] Manually adding refractory materials and scrap steel into the furnace is highly dangerous. Personnel need to be in front of the furnace mouth, and there is a risk of splashing and scalding. Therefore, a hopper is welded on the forklift, and the lining repair materials are tipped by the forklift. However, this method still has the problem of insufficient feeding depth, and the furnace protection effect still fails to meet the expectations. Summary of the Invention

[0004] The purpose of the utility model is to provide a material feeding device behind a converter furnace to solve the problems existing in the prior art.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] A material feeding device behind a converter furnace includes a bottom frame and a feeding hopper. A rear vertical plate is welded to the rear end of the bottom frame. Lower support plates are welded to both sides of the bottom frame. The two lower support plates are fixedly connected to upper support plates through a plurality of fixing plates. The rear ends of the upper support plates and the lower support plates are welded to the rear vertical plate. Stop baffles are bolted to the front ends of the upper support plates and the lower support plates. An upper guide rail is fixed to the bottom of the upper support plate, and a lower guide rail is fixed to the top of the lower support plate. A plurality of rollers are installed on both sides of the feeding hopper, and the rollers are all clamped between the upper guide rail and the lower guide rail.

[0007] Furthermore, both the upper support plate and the lower support plate are L-shaped. A plurality of reinforcing plates are welded inside the L-shaped structure of the lower support plate. Front vertical plates are welded to the front ends of the upper support plate and the lower support plate, and the stop baffles are bolted to the front vertical plates.

[0008] Furthermore, the fixing plate is in a U-shaped, and the fixing plate connects the upper support plate and the lower support plate from the outside.

[0009] Furthermore, the roller is a grooved track wheel, with the upper and lower guide rails located inside the groove of the roller. The roller slides against the lower guide rail, and there is a gap between the rolling surface of the roller and the upper guide rail. The rollers are located between the middle and the rear end of both sides of the feed hopper.

[0010] Furthermore, the front end and top surface of the feed hopper are open.

[0011] Furthermore, two fork-shaped feet are welded together on the outer sides of the bottom frame and the fixing plate.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with specific embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the scope of the utility model.

[0023] like Figure 1-4As shown in the figure, a material feeding device behind a converter includes a bottom frame 1 and a feeding hopper 2. A rear vertical plate 13 is welded to the rear end of the bottom frame 1. Lower support plates 4 are welded to both sides of the bottom frame 1. Both of the two lower support plates 4 are fixedly connected to an upper support plate 5 through a number of fixing plates 3. The rear ends of the upper support plate 5 and the lower support plates 4 are welded to the rear vertical plate 13. A stop plate 6 is bolted to the front ends of the upper support plate 5 and the lower support plates 4. An upper guide rail 7 is fixed to the bottom of the upper support plate 5, and a lower guide rail 8 is fixed to the top of the lower support plate 4. A number of rollers 9 are installed on both sides of the feeding hopper 2, and the rollers 9 are all clamped between the upper guide rail 7 and the lower guide rail 8.

[0024] Both the upper support plate 5 and the lower support plates 4 are L-shaped. Since the lower support plates 4 bear more weight, a number of reinforcing plates 10 are welded inside the L-shaped structure of the lower support plates 4, thus playing a role in strengthening the support of the lower support plates 4 and preventing the lower support plates 4 from deforming. Front vertical plates 11 are welded to the front ends of the upper support plate 5 and the lower support plates 4, and the stop plate 6 is bolted to the front vertical plates 11. The stop plate 6 is used to prevent the feeding hopper 2 from slipping out between the upper support plate 5 and the lower support plates 4. The bolted connection method of the stop plate 6 is convenient for disassembly. After removing the stop plate 6, the feeding hopper 2 can be pulled out for maintenance.

[0025] The fixing plates 3 are C-shaped. The fixing plates 3 connect the upper support plate 5 and the lower support plates 4 from the outside, and the fixing plates 3 play a role in strengthening the connection between the upper support plate 5 and the lower support plates 4 and preventing the upper support plate 5 and the lower support plates 4 from deforming.

[0026] The rollers 9 are grooved track wheels. The track wheels are usually of H-shaped, U-shaped, V-shaped, etc., and have a notch thereon, and the notch is clamped on the guide rail. In this embodiment, an H-shaped track wheel is adopted. Both the upper guide rail 7 and the lower guide rail 8 are located inside the notch of the roller 9. The roller 9 slides and abuts against the lower guide rail 8, and there is a gap between the rolling surface of the roller 9 and the upper guide rail 7. When there is no material in the feeding hopper 2, the roller 9 rolls on the lower guide rail 8. When adding materials to the feeding hopper 2, since the rollers 9 are all located between the middle and the rear end on both sides of the feeding hopper 2, the front end of the feeding hopper 2 is equivalent to being suspended. The materials may cause the feeding hopper 2 to tilt forward, then the rollers 9 close to the rear vertical plate 13 will be lifted and clamped on the upper guide rail 7.

[0027] The front end and the upper top surface of the feeding hopper 2 are open for receiving and feeding materials.

[0028] Two fork feet 12 are jointly welded to the outside of the bottom frame 1 and the fixing plates 3 for convenient installation on a forklift.

[0029] The working principle of the present utility model is:

[0030] In use, this utility model is mounted on a forklift using the fork legs 12. First, the forklift tilts the feed hopper 2 backward to add material into it. Then, the forklift raises the feed hopper 2 and moves it to the front of the furnace, allowing the feed hopper 2 to extend into the furnace. The forklift then tilts the feed hopper 2 forward, causing it to slide forward and extend deeper into the furnace, adding material. The forklift tilts backward again, causing the feed hopper 2 to slide backward, and then the forklift moves away, thus completing the material feeding process.

[0031] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention.

[0032] The technologies, shapes, and structures not described in detail in this utility model are all known technologies.
