Description

Technical Field

[0001] The utility model relates to the field of material surface leveling for a sintering machine trolley, in particular to an automatically adjustable arc-type material leveler for a sintering machine. Background Art

[0002] Sintering relies on air flow, which tends to flow in areas with good flow. When the material surface is uneven, the air volume passing through different locations on the material surface varies, causing the sintered ore to burn inconsistently, resulting in uneven agglomeration and poor sintered ore quality. The sintering process itself is a fluctuating one. Fluctuations in material feeding and the moisture content of the mixture ultimately lead to slight fluctuations in the material layer on the sintering machine's trolley. The existing leveler causes uneven force on the material surface during leveling, exacerbating variations in the overall porosity of the sintered material layer. This leads to inconsistent sintering air volume and resulting in inhomogeneous sintering. Utility Model Content

[0003] The purpose of the utility model is to provide an automatically adjustable arc type sintering machine flattener to solve the above problems.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] The utility model discloses an automatic adjustment circular arc type sintering machine flat material device, comprising a plurality of chains and circular arc flat material plates, one end of the chain is connected to the cross beam of the material distribution platform, the other end of the chain is connected to the circular arc flat material plate, and a counterweight component is provided on the top surface of the circular arc flat material plate.

[0006] Furthermore, there are five chains and five arc flat plates.

[0007] Furthermore, the length of the chain is 20 mm.

[0008] Furthermore, the length of the arc flat plate is 50 mm.

[0009] Furthermore, the counterweight assembly includes a threaded rod connected to the top surface of the arc flat plate, the bottom of the threaded rod is connected to a support plate, a number of counterweight blocks are sleeved on the threaded rod, and a pressure plate is pressed on the top surface of the topmost counterweight block, the pressure plate is sleeved on the threaded rod, and the pressure plate is locked and fixed by a nut threadedly connected to the threaded rod.

[0010] Furthermore, two adjacent arc flat plates are connected via a connecting ring.

[0011] Compared with the prior art, the beneficial technical effects of the present invention are:

[0012] Because the utility model is a circular arc flat material plate connected by a chain, it can automatically adjust according to material layers of different heights, ensuring the overall flatness of the material surface and the uniformity of wind energy through the material layer, providing a guarantee for homogeneous sintering, avoiding fluctuations in the quality of sintered ore caused by untimely adjustment due to negligence of personnel, and when the overall air permeability of the mixture is good, a counterweight block can be added to the circular arc flat material plate to achieve the purpose of compacting the surface mixture, so as to destroy the air permeability of the material layer and ensure a certain negative pressure. When the counterweight is not needed at other times, it can be removed by itself to improve the air permeability of the mixture. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] like Figure 1-2 As shown, an automatically adjustable arc type sintering machine flat material device includes five chains 1 and an arc flat material plate 2. The length of the chain 1 is 20 mm, and the length of the arc flat material plate 2 is 50 mm.

[0018] One end of the chain 1 is connected to the crossbeam 3 of the material distribution platform, and the other end of the chain 1 is connected to the circular arc flat material plate 2. Two adjacent circular arc flat material plates 2 are connected by a connecting ring 9.

[0019] A counterweight assembly is provided on the top surface of the arc flat plate 2, and the counterweight assembly includes a threaded rod 4 connected to the top surface of the arc flat plate 2, and the bottom of the threaded rod 4 is connected to a support plate 5. A number of counterweight blocks 6 are sleeved on the threaded rod 4, and a pressure plate 7 is pressed on the top surface of the topmost counterweight block 6. The pressure plate 7 is sleeved on the threaded rod 4, and the pressure plate 7 is locked and fixed by a nut 8 threadedly connected to the threaded rod 4.

[0020] When the trolley is empty of material, the chain 1 naturally droops, and when the trolley is full of material, the arc-shaped flat plate 2 rubs against the mixed material to form a natural bend. The use of an arc-shaped flat plate can stabilize the contact area between the plate and the material surface, that is, the height of the material layer changes but the contact area between the flat plate and the material surface remains basically unchanged, which is better than a straight plate. On the one hand, this flat material leveler will not destroy the air permeability of the material layer surface. On the other hand, when the raw material structure changes and the material needs to be pressed, the counterweight can be freely adjusted to achieve the purpose of pressing the material. It is suitable for sintering a variety of raw material structures. The utility model effectively solves the problem that the original flat material leveler cannot automatically adjust and cannot achieve a flat material surface when the material layer thickness fluctuates. It ensures that the overall material surface is flat and the wind can evenly pass through the material layer, providing a guarantee for homogeneous sintering.

[0021] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
