Description

Technical Field

[0001] The utility model relates to the technical field of feeding a melting furnace, in particular to a feeding conveying chain belt feeding plate of a melting furnace. Background Art

[0002] At present, the feeding method of the melting furnace in the steel plant is: the material is transported from the ground to the feeding port on the top of the furnace by using a conveyor chain belt for feeding. Multiple feeding plates are installed and fixed on the conveyor chain rail, and the head and tail of two adjacent feeding plates are superimposed to form a chain connection. The grabber loads the material into the conveyor chain belt, and the conveyor chain belt then delivers the material into the melting furnace.

[0003] After running for a period of time, the conveyor chain often jams and gets stuck, which causes the melting furnace to stop running. After field observation and analysis of the conveyor chain's material transportation operation, the causes are: 1. The conveyor belt's feeding chain plate is double-layered and hollow inside. When the grabber feeds the conveyor chain, the impact of large pieces of material falling causes the upper steel plate of the feeding plate to dent, causing the rigidity of the feeding plate to deform, and the two ends of the feeding plate rub against the frame and side baffles of the conveyor chain, causing jams. 2. The conveyor chain runs upward at a certain slope, and the feeding plate's material surface is flat, so the material slides down, and the pointed material is inserted between the two ends of the feeding plate and the side plates of the conveyor chain's frame, causing jams. Summary of the invention

[0004] In order to overcome the shortcomings of the above-mentioned prior art, the utility model provides a feeding plate for a melting furnace feeding conveyor chain. The material receiving surface is designed to be in a trapped state to hold the material to prevent it from sliding; a material blocking plate is provided to protect the running gap of the feeding plate from being stuck, thereby preventing the conveyor chain from being stuck or jammed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A feeding plate of a melting furnace feeding conveyor chain belt comprises a main board, side boards, a reinforcing rib plate and a material baffle plate; the main board comprises an upper parallel portion, a downward sloping portion and a lower parallel portion; the reinforcing rib plate is longitudinally fixed to the lower parallel portion, and the downward sloping portion, the lower parallel portion and the reinforcing rib plate form a material pocket; the side boards are fixed to both sides of the main board, and the material baffle plate is transversely fixed to the upper parallel portion.

[0007] Furthermore, the upper parallel portion of the mainboard is provided with a downward bend at the end, and the lower parallel portion is provided with an upward bend at the end.

[0008] Furthermore, a bolt hole is provided on the lower parallel portion of the main board, and the loading plate is fixed to the conveyor belt chain rail by bolts.

[0009] Furthermore, the width of the upper parallel portion of the main board is smaller than the width of the lower parallel portion, and the main board as a whole is narrow in the front and wide in the back.

[0038] The lower parallel portion 13 of the main plate 1 is provided with bolt holes 14, and the loading plate is fixed on the conveyor belt chain rail by bolts to form a whole with the conveyor belt chain.

[0039] The width of the upper parallel portion 11 of the main board 1 is smaller than the width of the lower parallel portion 13. The feeding plate is narrow in front and wide in the back. The main board 1 is made of a thickened wear-resistant plate with the front end bent downward and the rear end bent upward. The two feeding plates are superimposed and connected. Wear-resistant materials are used to extend the service life.

[0040] The side panels 2 are made of 8 mm thick manganese steel plates, and the two side panels 2 are vertically fixed to the two ends of the main board 1 .

The longitudinal reinforcing rib plate 3 plays a role in strengthening the rigidity of the loading plate, and at the same time forms a trap pocket with the main board 1 to prevent the material from sliding downward when the slope is running.

[0042] The flat plate 5 is made of 14mm thick manganese steel plate, and two flat plates 5 are provided. The flat plates 5 are horizontally welded to both ends of the main plate 1.

[0045] The sandwich vertical plates 6 at both ends act as partitions to prevent the slender scrap steel from being inserted and unable to be removed during operation.

[0046] Operation process: Multiple feeding plates are installed and fixed on the conveyor chain track. The adjacent feeding plates are stacked head to tail to form a chain connection. The grabber loads the scrap steel raw materials (materials) into the conveyor chain, and the conveyor chain then transports the raw materials (materials) into the electric furnace (melting furnace).

[0047] The main board 1 of the utility model is made of wear-resistant plate material, and the bending forming and the combination of the reinforcing rib plate 3 improve the rigidity of the feeding plate, the reinforcing rib plate 3 and the main board 1 form a trap to prevent the scrap steel raw material (material) from sliding when running on the slope, and the blocking plates 4 at both ends play a partitioning role to prevent the pointed scrap steel (material) from being inserted into the running gap between the feeding plate and the side plate of the conveyor belt and causing jamming.

[0048] The utility model can avoid the jamming and blocking of the conveyor chain belt.
