Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sintering technology, specifically relating to a sintering machine flattening and pressing device. Background Technology
[0002] In sintering production, the sintering material distribution directly affects the yield and quality of sintered ore. The sintering material distribution needs to possess a certain degree of uniformity and flatness. Existing technologies use scrapers or pressure rollers to flatten the sintering material surface: the mixture is spread across the trolley by a material distribution system, and the material layer is flattened by scrapers or pressure rollers. Due to the weight of the scrapers and pressure rollers and overall structural issues, the flattened material layer exhibits varying local density and differences in permeability along the width of the trolley. Furthermore, deep grooves on the material surface are difficult to smooth, severely impacting the sintering process. Additionally, the scraper makes line contact with the material surface, and accumulation is prone to occur at its leading edge in the incoming direction; localized wear or adhering material can lead to grooves on the material surface. Utility Model Content
[0003] The purpose of this invention is to provide a sintering machine material leveling and pressing device to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A sintering machine flattening and pressing device includes an H-beam, a flattening steel plate, hinges, a box, a pulley, a wire rope, a counterweight, and a support rod. The flattening steel plate is connected to the bottom of the H-beam at certain intervals via hinges. The box is fixedly connected to the upper part of the flattening steel plate. The counterweight is placed inside the box. A hook is welded to the front end of the flattening steel plate. One end of the wire rope is connected to the hook. The other end of the wire rope passes around the pulley. The pulley is fixed to the support rod, which is located on the upper part of the H-beam.
[0006] Preferably, a hook is fixedly connected to the box.
[0007] Preferably, the H-beam has connecting holes.
[0008] Preferably, it also includes an anti-detachment steel wire rope, one end of which is connected to a hook on the box, and the other end is connected to a connecting hole in an H-beam.
[0009] Preferably, there are multiple flat steel plates, each of which is fixedly connected with a box and a hook.
[0010] Preferably, the number of pulleys and wire ropes is the same as the number of hooks.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: by smoothing and compacting the mixed material surface through multiple sets of flat steel plates, the material surface of the trolley is flattened, which is conducive to the ignition of the material surface and to the uniform sintering speed of each area in the width direction of the trolley, and to the negative impact of the edge effect on both sides of the trolley; the flat material pressing device is in surface contact with the material surface of the trolley, which makes the material surface flatter, and the controllable pressing makes the material layer compaction moderate. The multiple sets of distribution can achieve different degrees of pressing in the width direction of the trolley, which can alleviate the phenomenon of uneven combustion speed caused by the edge effect and improve the quality of sintered ore.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Example:
[0017] Please see Figure 1 - Figure 2As shown, a sintering machine flattening and pressing device includes an H-beam 1, flattening steel plates 2, hinges 3, boxes 4, pulleys 5, steel wire ropes 6, counterweights 7, support rods 8, and a first hook 9. Four flattening steel plates 2 are connected at a certain distance to the bottom of the H-beam 1 via the hinges 3. In this embodiment, the two middle flattening steel plates 2 have a larger volume than the two flattening steel plates 2 on either side. Boxes 4 are fixedly connected to the upper part of the flattening steel plates 2, and counterweights 7 are placed inside the boxes 4. The two middle boxes 4 have a larger volume than the two boxes 4 on either side. The volume of box 4 is such that the pressing strength is adjusted by adjusting the number and weight of counterweights 7 inside box 4. Counterweights 7 are generally rectangular metal blocks. The front end of the flat steel plate 2 is welded with a first hook 9. One end of the steel wire rope 6 is connected to the first hook 9. The other end of the steel wire rope 6 passes around the pulley 5. The pulley 5 is fixed on the support rod 8. The support rod 8 is located on the upper part of the H-beam 1 and is fixed above the sintering machine's material feeding platform. In this embodiment, there are four pulleys 5, four steel wire ropes 6, and four first hooks 9.
[0018] Furthermore, four second hooks 10 are fixedly connected to the box 4. Four connection holes 11 are formed on the H-beam 1. The pressing device in this embodiment also includes four anti-detachment steel wire ropes 12. One end of each anti-detachment steel wire rope 12 is connected to the second hook 10 on the box 4, and the other end is connected to the connection hole 11 on the H-beam 1. The anti-detachment steel wire rope 12 is a steel wire rope buckle to prevent the flat steel plate 2 from falling off and being lost.
[0019] In this embodiment, the H-beam 1 is horizontally welded to the top of the sintering machine trolley, and four sets of flattening steel plates 2 are connected by hinges 3. When the sintering machine trolley, filled with the mixture, moves forward, the material surface first contacts the flattening steel plates 2, smoothing the surface. The pressure generated by the counterweight 7 and the gravity of the flattening steel plates 2 acts on the mixture, achieving material pressing. The lower limit of the flattening capacity of the flattening steel plates 2 is controlled by raising and lowering the wire rope 6, thereby controlling the pressing intensity. By controlling the lower limit of the flattening capacity of the four sets of flattening steel plates 2, the pressing intensity of different areas in the width direction of the trolley can be adjusted to mitigate the influence of edge effects on the combustion rate. As the sintering machine trolley continues to move, the material surface is gradually smoothed and compacted. After being flattened by this device, the material layer has moderate compactness and good flatness, which can avoid many problems existing in traditional material distribution, thereby improving the sintering quality.
[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
