Description

Technical Field

[0001] This utility model relates to the field of sintering equipment technology, and in particular, to a steel beam heat insulation component and a tail bucket support beam for a sintering machine. Background Technology

[0002] Various powdered iron-containing raw materials, mixed with appropriate amounts of fuel and flux, are sintered in a sintering device to bind the mineral powder particles into lumps, forming hot ore with a temperature as high as 200℃ and considerable hardness. The hot ore causes long-term heat radiation to the tail bucket support beams of the sintering machine on both sides, affecting structural safety. Therefore, heat insulation layers are installed on both sides and the bottom of the steel beams. However, the outer steel plate of the heat insulation layer is prone to deformation and wear.

[0003] In existing technologies, heat insulation is achieved by using a combination of I-beams, insulation layers, and protective steel plates. However, due to the many sharp edges of hot ore, the protective steel plates are subject to significant impact from the material, making them prone to wear and deformation. They often need to be replaced, and the downtime caused by replacement work results in a significant increase in operating costs and maintenance.

[0004] In view of this, it is necessary to propose a steel beam heat insulation component and a sintering machine tail bucket support beam to solve or at least alleviate some of the above-mentioned defects. Utility Model Content

[0005] The steel beam insulation component and sintering machine tail bucket support beam provided by this utility model solve the technical problem that the existing steel beam insulation layer is easily damaged by impact.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A steel beam thermal insulation component includes a steel beam body, a thermal insulation layer, a steel protective layer, and a material accumulation buffer platform. The thermal insulation layer is arranged in close contact with the steel beam body, and the steel protective layer is located on the side of the thermal insulation layer away from the steel beam body. A material accumulation buffer platform is arranged on the material guiding sidewall of the steel protective layer away from the thermal insulation layer. The first end of the material accumulation buffer platform is fixedly connected to the steel protective layer, and the second end of the material accumulation buffer platform is cantilevered outward. The second end of the material accumulation buffer platform and the material guiding sidewall enclose a material accumulation buffer groove with an upper opening.

[0008] Furthermore, the material accumulation buffer platform can be a single layer or multiple layers, with the multiple layers of material accumulation buffer platforms arranged at intervals along the height direction.

[0009] Furthermore, each layer of material accumulation buffer platform is arranged to extend horizontally.

[0010] Furthermore, each layer of material accumulation buffer platform is arranged continuously or intermittently, with the gaps between adjacent layers of material accumulation buffer platforms along the height direction being staggered.

[0011] Furthermore, the material accumulation buffer platform includes a material accumulation plate and reinforcing connecting ribs. The first end of the material accumulation plate is fixedly connected to the steel protective layer, the second end of the material accumulation plate is cantilevered outward, and the reinforcing connecting ribs are connected between the material accumulation plate and the steel protective layer.

[0012] Furthermore, the material accumulation plate is a flat steel plate, angle steel, or U-shaped channel steel.

[0013] Furthermore, it also includes a longitudinal stiffening steel plate, the first end of which is fixedly connected to the steel beam, and the second end of which extends into the insulation layer.

[0014] Furthermore, a heat insulation pad is arranged at the bottom of the steel beam, and / or a floor slab is arranged at the top of the steel beam.

[0017] This utility model has the following beneficial effects:

[0018] This utility model discloses a steel beam heat insulation component and a sintering machine tail bucket support beam, comprising a steel beam body, a heat insulation layer, a steel protective layer, and a material accumulation buffer platform. By sequentially arranging the heat insulation layer and the steel protective layer on the side wall of the steel beam body, heat insulation of the steel beam body and protection of the heat insulation layer are achieved.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0029] Please refer to Figure 1The present invention provides a steel beam heat insulation component, comprising a steel beam body, a heat insulation layer, a steel protective layer, and a material accumulation buffer platform. The heat insulation layer is arranged in close contact with the steel beam body, and the steel protective layer is located on the side of the heat insulation layer away from the steel beam body. A material accumulation buffer platform is arranged on the material guiding side wall of the steel protective layer away from the heat insulation layer. The first end of the material accumulation buffer platform is fixedly connected to the steel protective layer, and the second end of the material accumulation buffer platform is cantilevered outward. The second end of the material accumulation buffer platform and the material guiding side wall enclose a material accumulation buffer groove with an upper opening.

[0030] This utility model provides a steel beam thermal insulation component, including a steel beam body, a thermal insulation layer, a steel protective layer, and a material accumulation buffer platform. By sequentially arranging the thermal insulation layer and the steel protective layer on the side wall of the steel beam body, thermal insulation of the steel beam body and protection of the thermal insulation layer are achieved. By arranging the material accumulation buffer platform on the material guiding side wall of the thermal insulation layer, the material accumulation buffer platform has a material accumulation buffer groove with an upper opening. When the initial material enters, it will accumulate and be stored in the material accumulation buffer groove. When subsequent material enters, it will collide with the stored material and be discharged along the material guiding side wall. This avoids the direct impact contact between excessive material and the steel protective layer in the prior art, and solves the technical problem that the existing steel beam thermal insulation layer is easily damaged by impact.

[0031] Optionally, the steel beam is a steel structural component; the steel protective layer is a steel structural component; and the material buffer platform is also a steel structural component.

[0032] Furthermore, the material accumulation buffer platform can be a single layer or multiple layers, with the multiple layers arranged at intervals along the height direction. It is understood that in this invention, the material accumulation buffer platform can be a single layer or multiple layers. In a preferred embodiment of the invention, to improve the structural strength and protective strength of the steel protective layer, the material accumulation buffer platform is provided in at least three layers, with the multiple layers arranged at intervals along the height direction.

[0033] Preferably, the material accumulation buffer platform is arranged near the middle and lower part of the steel protective layer.

[0034] Furthermore, each layer of material accumulation buffer platform is arranged horizontally. Understandably, in order to protect the entire cross-section, the two ends of the material accumulation buffer platform are arranged flush with the two ends of the steel protection.

[0035] Furthermore, each layer of material accumulation buffer platform is arranged continuously or intermittently, with the gaps between adjacent layers of material accumulation buffer platforms along the height direction staggered. In this invention, by staggering the gaps between adjacent layers of material accumulation buffer platforms along the height direction, protection is achieved while ensuring the amount of material discharged.

[0036] Furthermore, the material accumulation buffer platform includes a material accumulation plate and reinforcing connecting ribs. The first end of the material accumulation plate is fixedly connected to the steel protective layer, and the second end of the material accumulation plate is cantilevered outward. The reinforcing connecting ribs connect the material accumulation plate and the steel protective layer. It can be understood that in this invention, the material accumulation plate and the steel protective layer can be welded together, or they can be fixedly connected by fasteners.

[0037] Furthermore, the material accumulation plate is a flat steel plate, angle steel, or U-shaped channel steel. Preferably, unequal-sided angle steel is used in this invention. Understandably, the angle steel type and spacing can be selected in different sizes depending on the specific project. Depending on the beam height, different numbers of longitudinal stiffening steel plates can also be added to improve wear resistance.

[0038] Furthermore, the steel beam insulation component also includes longitudinal stiffening steel plates. The first end of the longitudinal stiffening steel plate is fixedly connected to the steel beam body, and the second end of the longitudinal stiffening steel plate extends into the insulation layer. In this utility model, the longitudinal stiffening steel plates are arranged according to the actual height of the steel beam body. The longitudinal stiffening steel plates can be arranged in one layer or multiple layers.

[0039] Furthermore, a heat insulation pad is arranged at the bottom of the steel beam. In a preferred embodiment of this utility model, the heat insulation pad covers the bottom of the steel beam.

[0040] Furthermore, a floor slab is arranged on top of the steel beam.

[0041] Furthermore, the steel beam is an I-beam or H-beam, the insulation layer is arranged flush with the web of the steel beam in the height direction, the steel protective layer is arranged flush with the web of the steel beam in the height direction, and the sidewall of the steel protective layer is arranged flush with the sidewall of the steel beam.

[0042] According to the principles of fluid and granular mechanics, the protective steel plate of the beam side insulation layer is easily impacted by flowing materials, leading to deformation and wear. With the steel beam insulation structure of this invention, material will accumulate on the angle steel, greatly reducing wear on the steel protective layer and increasing its service life. The protective steel plate (steel protective layer) and the angle steel form a combined cross-section, increasing overall rigidity and preventing deformation of the protective steel plate. The angle steel type and spacing can be selected according to different projects. Depending on the beam height, longitudinal stiffening steel plates can also be added to improve wear resistance.

[0043] Please refer to Figure 2 This utility model also provides a sintering machine tail bucket support beam, including the aforementioned steel beam heat insulation components. Multiple steel beam heat insulation components are arranged along the four sides and spliced ​​together head-to-head to form a closed structure with a material guiding cavity. Preferably, adjacent steel beam heat insulation components are welded together at the corners.

[0044] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
