Description

Technical Field

[0001] The utility model relates to a material surface leveling device for a sintering machine platform, belonging to the technical field of sintering machine equipment in the metallurgical industry. Background Art

[0002] The production process of the sintering machine is to add iron-containing materials, flux, solid fuel, return ore and other miscellaneous materials according to a certain ratio, mix them in the primary and secondary mixers, make balls, and evenly distribute the mixture to the sintering machine trolley through the main ore trough, round roller, nine-roller (or other equipment) material distribution equipment. Then the sintering machine trolley is driven by the head star wheel to run continuously. The mixture is sintered by exhaust after passing through the ignition furnace. The mixture arranged on the trolley is graded and evenly and flatly spread on the trolley. At the same time, the material surface on both sides of the trolley is required to be compacted to reduce the edge leakage effect.

[0003] In order to make the material surface on the trolley flat and compact, a material leveling device is mostly used on the material surface of the sintering machine trolley. The current material leveling device is to fix both sides of a round tube on the column, fix a whole steel plate on the round tube, and use the steel plate to directly scrape and compact the material surface. This material leveling device has the following shortcomings:

[0004] First, it is easy to cause the middle part of the material surface to be compacted and the two sides to become loose, making the middle part of the sintering machine poorly permeable and difficult to burn through, affecting the quality and strength of the sintered ore. At the same time, it is easy to cause air leakage on both sides, affecting production efficiency.

[0005] Secondly, the leveling device installed on the sintering machine trolley is fixed and cannot be adjusted up and down according to the height of the material surface. In addition, during sintering production, the requirements for the air permeability of the material layer vary depending on the raw material structure, and the compacting weight cannot be adjusted, which affects the output and quality of the sintered ore. Utility Model Content

[0006] The utility model aims to provide a material surface leveling device for a sintering machine trolley, which can ensure the flatness of the material surface, avoid the phenomenon of being compacted in the middle and loose on both sides, and solve the problems existing in the background technology.

[0007] The technical solution of the utility model is:

[0008] A sintering machine trolley material surface leveling device, the device is installed above the sintering machine trolley material surface, it comprises a manual pulley, a wire rope, an arc plate, a counterweight, a rotating shaft, a fixing nut and a lead screw, three arc plates are connected together side by side through the lead screw and the fixing nuts at both ends of the lead screw, and the overall width thereof matches the width of the trolley, one end of the three arc plates is rotatably connected to the sintering machine trolley frame through a rotating shaft, and the other ends of the three arc plates are respectively provided with a counterweight, and each arc plate is connected with a wire rope and a manual pulley.

[0009] The width of the arc-shaped plates at the two ends of the three arc-shaped plates is smaller than the width of the arc-shaped plate in the middle.

[0010] Rib plates are fixed on the three arc-shaped plates in their length directions, and the counterweights are fixed on the rib plates.

[0011] The ribs in the length direction of the three arc-shaped plates are connected together through a lead screw and fixing nuts at both ends of the lead screw.

[0012] The steel wire and steel rope are connected with the arc plate through a fixing ring.

[0013] The fixing ring is fixed in the middle of the arc plate.

[0014] Vertical plates are respectively arranged on both sides of each arc-shaped plate.

[0015] The beneficial effects of the utility model are as follows: the device has a simple structure, is easy to install, maintain and adjust, can be adjusted in height and left and right horizontal directions as needed, can be adjusted individually or as a whole, ensures the flatness of the material surface, and reduces air leakage caused by edge effects by appropriately increasing or decreasing the arc plates on both sides, i.e., counterweights, thereby meeting the flat material requirements of sintering production and improving the yield and quality of sintered ore.

The three arc plates 4 are used in combination. Each of the three arc plates has a manual pulley 1 to adjust the height. A counterweight 5 is added above the three arc plates 4. The weight of the leveling device can be adjusted according to the needs of the mixture structure to better meet the leveling requirements of different mixture structures.

[0024] The manual pulley 1 is installed to facilitate manual adjustment of the height of the leveling device to meet the height of different mixed material surfaces.
