Description

Technical Field

[0001] This utility model relates to the technical field of steelmaking feeding equipment, and in particular to a mobile converter feeding device. Background Technology

[0002] In steel production enterprises, converters are used for steelmaking. The raw materials for converter steelmaking include molten iron, scrap steel, and ferroalloys, with scrap steel and alloy raw materials being the most abundant. This involves the equipment for feeding scrap steel into the converter. Currently, converter feeding equipment generally uses gantry cranes to feed the material into the converter opening. Gantry cranes typically use large-tonnage buckets loaded with large quantities of scrap steel, which are then moved and transported in the air. During feeding, operators need to adjust the position of the buckets multiple times to align with the converter opening and simultaneously raise and lower the position. This operation is carried out in the air, which is relatively time-consuming and labor-intensive, and also poses certain risks to operational safety. Therefore, it is necessary to design a more mobile, flexible, and easy-to-operate feeding device. Utility Model Content

Furthermore, the mobile vehicle body has a mobile base plate 9, and the bottom of the mobile base plate is provided with rolling wheels 10. The rolling wheels are driven by a motor. A front lifting cylinder 8 is provided at the front of the mobile vehicle body, and a rear lifting cylinder 3 is provided at the rear of the mobile vehicle body. The piston rods of the front lifting cylinder and the rear lifting cylinder are connected to a feeding trough 6.

[0018] Furthermore, the present invention provides two sets of rear lifting cylinders and one set of front lifting cylinders. The piston rod of the front lifting cylinder is hinged to the bottom of the front end of the feeding trough. The two sets of rear lifting cylinders are symmetrically arranged on both sides of the rear bottom of the feeding trough. The piston rod of the rear lifting cylinder is hinged to the feeding trough. The cylinder seat of the rear lifting cylinder is hinged on the corresponding inclined base 2. The inclined base is placed on the mobile vehicle body. The front end of the feeding trough is provided with a flat groove material outlet 7.

[0019] Furthermore, the flat trough feed opening described in this utility model is constructed by assembling and laying wedge-shaped refractory bricks 12. The wedge-shaped refractory bricks are assembled in blocks and supported by a high-temperature resistant metal frame. A pushing mechanism is provided at the rear of the feeding trough, which pushes the steel scraps in the feeding trough into the furnace opening 13 of the corresponding converter through the flat trough feed opening. A pressing weight 1 is also provided at the rear of the moving vehicle body.

[0020] Furthermore, the cross-section of the feeding trough in this utility model is a V-shaped groove, and the opening of the flat trough is wide at one end and narrow at the other end. The wide end of the flat trough opening is connected to the front end of the feeding trough.

[0021] Furthermore, the pushing mechanism of this utility model includes a pushing base plate 4, which is welded and fixed at the middle position of the rear end of the feeding trough. A pushing cylinder 5 is installed on the pushing base plate, and the piston rod of the pushing cylinder is set towards the feeding trough.

[0023] In the above embodiment, the wedge-shaped refractory bricks in the flat trough are spliced ​​together piece by piece, and a grid-shaped high-temperature resistant metal frame is used around and at the bottom. The wedge-shaped refractory bricks are spliced ​​together and fixed one by one, and the surface is polished smooth to facilitate the sliding of scrap steel raw materials.

[0024] The feeding operation of this invention is carried out as follows:

[0025] First, the scrap steel raw materials are gripped and placed into the feeding trough of this utility model using gripping equipment such as electromagnets. After the feeding trough is full, the moving vehicle is moved to the corresponding position until it reaches the furnace mouth of the converter body. Then, the front lifting cylinder and the rear lifting cylinder are activated simultaneously until the flat trough material outlet is aligned with the furnace mouth. At this time, the rear lifting cylinder is raised to a relatively higher height, which makes it easier to push the raw materials into the furnace mouth. After the preparation work is completed, the pushing cylinder is activated, and the pushing plate is activated. The pushing plate pushes the scrap steel raw materials in the feeding trough into the furnace mouth together, realizing a feeding operation.

[0026] After feeding is complete, start the walking motor to move the entire equipment away flexibly before proceeding with the next feeding operation.
