Abstract
Description
Technical Field
[0001] The utility model relates to a buffer bin for sintering bed material. Background Art
[0002] During the sintering production process, loading, ignition, and sintering are carried out on the sintering machine trolley, and the sintered ore is discharged at the tail. Before loading the raw materials onto the trolley, a layer of sintered finished ore is laid as the bottom material to protect the grate bars and prevent the raw materials from being embedded in the gaps between the grate bars and affecting the air permeability. Laying the bottom material can improve the quality of the sintered ore, protect the grate bars, reduce the dust removal load, and extend the life of the fan rotor. However, due to the influence of long-term operation and high temperature and high pressure environment, sintering equipment is prone to wear, air leakage and other problems, so regular inspection and maintenance work is essential. Before sintering inspection and maintenance, the materials are usually emptied and then shut down for inspection and maintenance. As a result, there will be a lack of bottom material for a period of time each time the sintering system is restarted, and the mixed ore is directly laid on the trolley, which seriously affects the service life of the equipment and the quality of the sintered ore. Utility Model Content
[0003] In order to overcome the above-mentioned defects, the utility model provides a buffer bin for sintering bed material.
[0004] To achieve the above purpose, the utility model of the sintering bottom material buffer bin comprises a buffer bin body, the upper part of the buffer bin body is cylindrical; the lower part of the buffer bin body is inverted cone; a first discharge port is opened on the lower side wall of the upper part of the buffer bin body;
[0005] A second discharge port is reserved in the center of the steel bin at the lower part of the buffer bin body, and a feeding gate is arranged at the second discharge port.
[0006] Furthermore, a chute is arranged outside the first discharge port.
[0007] Furthermore, a feeding belt conveyor is arranged at the upper opening of the buffer bin body.
[0008] Furthermore, the upper part of the buffer bin body is a concrete structure.
[0009] Furthermore, the lower part of the buffer bin body is a steel structure.
[0010] Furthermore, a lower discharging belt conveyor is provided at the first discharging port and the second discharging port.
[0011] Furthermore, the center lines at the first discharge port and the second discharge port are simultaneously located on the center line of the lower discharge belt conveyor.
[0012] Furthermore, the angle between the first discharge port and the horizontal line is greater than 40°.
[0013] In order to achieve the above-mentioned object, the utility model provides a method for discharging sintering bed material buffer bin, characterized in that the method comprises the following steps:
[0014] During normal production, the second discharge port is closed and the first discharge port is always open, so that a certain amount of material is stored in the bin; when the material accumulates at the first discharge port, it begins to flow from the first discharge port through the chute to the discharge belt conveyor; when the sintering system is restarted after being shut down for inspection and maintenance, the lower feeding valve is opened to ensure that there is no sintering without base material in the sintering system.
[0015] Furthermore, the upper edge of the first discharge port is 5-100 mm below the critical line of the bottom material accumulation in the figure.
[0016] When the utility model works normally, the lower discharge port of the cone section is closed, and the upper concrete side wall discharge port is always open, so a certain amount of material is stored in the warehouse. When the material accumulates to the upper outlet, it starts to flow from the upper outlet to the discharge belt conveyor through the chute; when the sintering system is restarted due to overhaul and maintenance, the lower feeding valve is opened to ensure that there is no sintering without bottom material in the sintering system.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0024] Example 1
[0025] like Figure 1 As shown, during the actual construction process, a sintering bed material buffer bin of the utility model is built in the same factory building as a sintering secondary mixer. The sintering bed material buffer bin of the utility model is located outside the discharge end of the secondary mixer so that the discharge belt conveyor of the bed material bin and the discharge belt conveyor of the secondary mixer can share a corridor to supply materials to the sintering main factory building.
[0026] like Figure 2 and Figure 3 As shown, a sintering bed material buffer bin of the utility model comprises a buffer bin body 2, wherein the upper part 21 of the buffer bin is square cylinder-shaped and has a concrete structure, and the lower part 22 is conical cylinder-shaped and has a steel structure. A feeding belt conveyor 1 is arranged above the buffer bin body 2, and a discharging belt conveyor 6 is arranged at the lower part.
[0027] A first discharge port 3 is provided on the upper conical concrete side wall, and bolts are pre-buried outside the first discharge port so as to be connected to the discharge chute 4.
[0028] A second discharge port 5 is reserved in the center of the lower steel bin, and a feeding gate is arranged at the lower part of the second discharge port.
[0029] Example 2
[0030] As a further improvement of the above-mentioned embodiment, the sintering bed material buffer bin of the utility model can store about 3 hours of bed material for normal sintering production.
[0031] Example 3
[0032] As a further improvement of the above embodiment, the side wall discharge port and the lower discharge port are both located on the center line of the lower discharge belt conveyor, and the materials discharged from the two discharge ports all fall onto the same belt conveyor.
[0033] Example 4
[0034] As a further improvement of the above embodiment, the first discharge port forms a certain angle (greater than 40°) with the horizontal line to ensure that the base material can flow out smoothly without being blocked.
[0035] Example 4
[0036] As a further improvement of the above embodiment, the upper edge of the first discharge port is slightly lower than the critical line (40°) of the bottom material accumulation in the figure, generally 5-100mm. This can maximize the use of warehouse capacity and maximize the storage of materials, and ensure that the material can be smoothly discharged from the upper discharge port after being stored to a certain amount.
[0037] Example 5
[0038] The discharging method of the utility model comprises the following steps:
[0039] During normal production, the lower discharge port of the cone section is closed, and the upper concrete side wall discharge port is always open. Therefore, a certain amount of material is stored inside the silo. When the material accumulates at the upper outlet, it begins to flow from the upper outlet through the chute to the discharge belt conveyor. When the sintering system is restarted after being shut down for inspection and maintenance, the lower feeding valve is opened to ensure that there is no sintering without base material in the sintering system.
[0040] The utility model is described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments, and various changes can be made within the knowledge of ordinary technicians in the field without departing from the purpose of the utility model. Many other changes and modifications that do not depart from the concept and scope of the utility model should be considered as the protection scope of the utility model.
[0041] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.
[0042] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
