Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary components for sintering machines, and in particular to an automatic adjustment device for the material leveling rollers on both sides of a sintering machine. Background Technology

[0002] A sintering machine is a piece of equipment used for sintering iron ore powder. It is the main equipment in the blast sintering process and can sinter concentrate powder and rich ore powder of different compositions and particle sizes into blocks, and partially eliminate harmful impurities such as sulfur and phosphorus contained in the ore. With the development of ironmaking technology, the requirements of blast furnace for sintered ore are constantly increasing. In order to effectively improve the quality and output of sintered ore, sintering equipment has been innovated and improved.

[0003] Existing sintering machine equipment has the following drawbacks: Analysis of the distribution pattern of the nine-roller material distribution system in the width direction of the sintering machine reveals that the particle size of the overall mixture is finer in the middle and slightly coarser on both sides, resulting in a generally high air leakage rate on both sides of the sintering machine, low finished product yield on both sides of the material surface, and a large number of returned ore particles. Therefore, how to increase the finished product yield of the mixture on both sides of the sintering machine and reduce the returned ore rate is a technical problem that urgently needs to be solved by those skilled in the art. To this end, we propose an automatic adjustment roller leveling device for the material surface on both sides of the sintering machine. Utility Model Content

[0004] The main purpose of this utility model is to provide an automatic adjustment roller leveler for the material surface on both sides of a sintering machine. The roller leveler is designed to press the material surface on both sides of the sintering machine, improve the sealing effect between the mixture and the guard plate, promote the marginal benefits of the mixture sintering machine, and thus improve the yield of the sintering machine. This can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An automatic adjustment material leveling device for the material surface pressure rollers on both sides of a sintering machine includes a sintering machine material distribution platform beam and a pressure roller. Sector-shaped plates are welded to both sides of the bottom of the sintering machine material distribution platform beam, and the pressure roller is movably connected to the bottom of the beam. Rectangular plates are movably connected between the sector-shaped plates, with one end of the rectangular plate away from the sector-shaped plates connected to the pressure roller. A connecting rod shaft is horizontally inserted inside the pressure roller, and both ends of the connecting rod shaft are welded to the ends of the rectangular plates. A crossbar is welded between the rectangular plates, and a through hole A is opened in the middle of the crossbar. A through hole B is opened inside the sintering machine material distribution platform beam, and a chain is wound between through hole A and through hole B.

[0007] Furthermore, both ends of the connecting rod shaft are fitted with pressure caps, and the pressure caps are fixed to the ends of the pressure roller; the pressure caps located at both ends of the pressure roller have a closing effect on the ends of the pressure roller.

[0008] Furthermore, a pin is inserted between the inside of the sector plates and the pin passes through the end of the rectangular plate; the pin passes through the rectangular plate and is inserted into the inside of the sector plate, so that the rectangular plate can deflect around the pin.

[0009] Furthermore, a positioning groove A is provided at the bottom of the inner wall of the through hole B near the pressure roller, and a positioning groove B is provided at the bottom of the inner wall of the through hole B away from the pressure roller; the positioning groove A and positioning groove B are spaced apart from the pressure roller. In use, the top of the chain is located inside the positioning groove A, so that the pressure roller can normally compact the material. When the pressure roller is not needed, the top of the chain can be moved to the positioning groove B, thereby causing the rectangular plate to deflect around the fan-shaped plate and raising the height of the pressure roller.

[0010] Compared with the prior art, this utility model has the following beneficial effects: Fan-shaped plates are welded to both sides of the bottom of the crossbeam of the sintering machine's feeding platform. Rectangular plates are connected inside the fan-shaped plates via pins, allowing the rectangular plates to rotate around the fan-shaped plates. A pressure roller is installed at the other end of the rectangular plate via a connecting rod shaft. The pressure roller is aligned with the edges of the sintering machine's feeding trolley. In use, the pressure roller falls onto the top of the material on both sides of the feeding trolley and adheres to the material surface. As the feeding trolley moves, the friction of the material drives the pressure roller to rotate. Simultaneously, the pressure roller's own weight presses down on the top of the material on both sides, effectively compacting the material. The material surface at the edges is appropriately compressed, reducing air leakage on both sides of the trolley side panels, increasing the effective use of airflow, promoting the marginal benefits of the mixed material sintering machine, significantly increasing the finished product rate on both sides of the sintering machine, effectively reducing the return ore rate, and simultaneously making the sintered ore surface flat and aesthetically pleasing.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figure 1-4 As shown, an automatic adjustment material leveling device for the material surface pressure rollers on both sides of a sintering machine includes a sintering machine material distribution platform beam 1 and a pressure roller 3. Sector-shaped plates 2 are welded to both sides of the bottom of the sintering machine material distribution platform beam 1, and the pressure roller 3 is movably connected to the bottom of the sintering machine material distribution platform beam 1. A rectangular plate 6 is movably connected between the sector-shaped plates 2, and the end of the rectangular plate 6 away from the sector-shaped plates 2 is connected to the pressure roller 3. A connecting rod shaft 5 is horizontally inserted inside the pressure roller 3, and both ends of the connecting rod shaft 5 are welded to the ends of the rectangular plate 6. A crossbar 8 is welded between the rectangular plates 6, and a through hole A9 is opened in the middle of the crossbar 8. A through hole B11 is opened inside the sintering machine material distribution platform beam 1, and a chain belt 10 is wound between the through hole A9 and the through hole B11.

[0018] In this configuration, pressure caps 4 are fitted onto both ends of the connecting rod shaft 5, and the pressure caps 4 are fixed to the ends of the pressure roller 3. A pin 7 is inserted between the fan-shaped plates 2 and passes through the ends of the rectangular plate 6. The pressure caps 4 located at both ends of the pressure roller 3 close the ends of the pressure roller 3. The pin 7 passes through the rectangular plate 6 and is inserted into the inside of the fan-shaped plate 2, so that the rectangular plate 6 can deflect around the pin 7.

[0019] The inner wall of the through hole B11 has a positioning groove A12 at the bottom near the pressure roller 3, and a positioning groove B13 at the bottom away from the pressure roller 3. The positioning grooves A12 and B13 are spaced apart from the pressure roller 3. In use, the top of the chain belt 10 is located inside the positioning groove A12, allowing the pressure roller 3 to compact the material normally. When the pressure roller 3 is not needed, the top of the chain belt 10 can be moved into the positioning groove B13, thereby causing the rectangular plate 6 to deflect around the fan-shaped plate 2 and raising the height of the pressure roller 3.

[0020] It should be noted that this utility model is an automatic adjustment roller leveling device for the material surface on both sides of a sintering machine. During operation, fan-shaped plates 2 are welded to both sides of the bottom of the crossbeam 1 of the sintering machine's material distribution platform. The inside of the fan-shaped plates 2 is connected to a rectangular plate 6 through pins 7, allowing the rectangular plate 6 to deflect around the fan-shaped plates 2. A pressure roller 3 is installed at the other end of the rectangular plate 6 through a connecting rod shaft 5. The pressure roller 3 is aligned with the edges of the two sides of the feeding trolley of the sintering machine. In use, the pressure roller 3 falls into the material on both sides of the top of the feeding trolley and adheres to the material surface. As the feeding trolley moves, the friction of the material drives the pressure roller 3 to rotate. At the same time, the pressure roller 3 presses down on the top of the material on both sides due to its own weight, which can compact the material on both sides. The material surface on both sides is appropriately pressed, reducing air leakage on both sides of the trolley sideboard, increasing the effective use of air volume, promoting the marginal benefits of the mixed material sintering machine, greatly increasing the finished product rate on both sides of the sintering machine, effectively reducing the return ore rate, and making the sintered ore surface flat and beautiful.
