Description

Technical Field

[0001] This utility model relates to the field of slag retaining wall technology, specifically to a slag retaining wall with excellent high-temperature resistance and fire resistance. Background Technology

[0002] A slag retaining wall is an enclosure structure made of sturdy materials, mainly used to block and filter solid particulate matter, preventing it from entering the equipment or affecting the surrounding environment. The main function of a slag retaining wall is to protect the normal operation of industrial equipment and construction projects, extend their service life, and prevent environmental pollution and safety hazards. It can effectively reduce the damage of solid particulate matter to equipment and the environment by blocking and filtering.

[0003] Existing slag retaining wall materials, such as concrete and brick, have good compressive strength and durability, but their performance will deteriorate significantly under high temperature environments. For example, a tundish slag retaining wall disclosed in patent CN210280651U does not have high-temperature fire resistance. Under high temperature environments, the material of the slag retaining wall may suffer structural instability due to thermal expansion, thermal stress, and other factors, resulting in cracking, peeling, and other phenomena, thus affecting its overall strength and stability. Due to material aging and performance degradation under high temperature environments, the maintenance and replacement costs of the slag retaining wall will increase significantly.

[0004] Therefore, it is necessary to invent a high-temperature resistant and fireproof slag retaining wall to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a slag retaining wall with excellent high-temperature resistance and fire resistance, in order to solve the problem that existing technologies lack high-temperature resistance and fire resistance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistant and fire-resistant slag-retaining wall, comprising a planar slag-retaining wall and an inclined slag-retaining wall, wherein inclined slag-retaining walls are provided on the left and right sides of the planar slag-retaining wall, a basic structural layer is provided at the innermost part of the planar slag-retaining wall and the inclined slag-retaining wall, a reinforcing layer is provided on the left and right sides of the basic structural layer, a horizontal supporting keel and a vertical supporting keel are provided on the reinforcing layer, a heat insulation layer is provided on one side of the reinforcing layer, a fireproof and flame-retardant layer is provided on one side of the heat insulation layer, and a protective layer is provided on the outermost part of the planar slag-retaining wall and the inclined slag-retaining wall.

[0007] Preferably, the planar slag retaining wall and the inclined slag retaining wall are provided with support feet at the bottom of the front and rear ends. The support feet are designed with a triangular structure and multiple support feet are provided. The use of multiple support feet further enhances the overall stability of the slag retaining wall and ensures its safety and reliability under high temperature and heavy load conditions.

[0008] Preferably, the planar slag retaining wall and the inclined slag retaining wall are provided with steel flow holes, and four steel flow holes are provided. The four steel flow holes can ensure that the molten metal flows evenly in multiple directions and improve the slag retaining efficiency.

[0009] Preferably, the interior of the four steel flow holes is fitted with anti-corrosion sleeves made of zirconia ceramic material. The outer wall of the anti-corrosion sleeves fits tightly with the inner diameter of the steel flow holes. The anti-corrosion sleeves can protect the slag retaining wall from corrosion by molten metal and slag, and extend its service life.

[0010] Preferably, multiple horizontal and vertical support keels are provided, and the multiple horizontal and vertical support keels are welded together in an intersecting manner. The multiple horizontal and vertical support keels can form a stable support network, which improves the deformation resistance and load-bearing capacity of the retaining wall.

[0011] Preferably, the heat insulation layer consists of two layers, both of which are made of ceramic fiberboard. The heat insulation layer can more effectively reduce heat transfer, lower the internal temperature of the retaining wall, and protect the foundation structure from high temperatures.

[0012] Preferably, the fireproof and flame-retardant layer is made of rock wool board material, and the fireproof and flame-retardant layer is tightly bonded to the heat insulation layer. The fireproof and flame-retardant layer can further improve the fire resistance of the slag retaining wall and ensure safety and reliability in extreme situations such as fires.

[0013] Preferably, the protective layer is wrapped around the outside of the basic structural layer, the reinforcing layer, the heat insulation layer and the fireproof and flame-retardant layer. The protective layer is an inorganic fiber spraying material. The protective layer can form an effective protective barrier to prevent external fire sources and high temperatures from damaging the internal structure of the slag retaining wall.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model, through its multi-layer structure design, including a basic structural layer, a reinforcing layer, a heat insulation layer, a fire-retardant layer, and a protective layer, enables the slag retaining wall to effectively withstand high-temperature environments, reduce heat transfer, and prevent the spread of fire. Furthermore, the inorganic fiber spraying material, as a protective layer, forms an effective protective barrier that can resist damage to the internal structure of the slag retaining wall from external fire sources and high temperatures. Thus, the slag retaining wall not only has excellent high-temperature resistance and fire resistance, but also maintains overall stability and extends its service life in harsh working environments, providing reliable safety assurance for industrial applications.

[0016] 2. In this utility model, multiple horizontal and vertical support keels are welded together to form a stable support network, which effectively improves the deformation resistance and load-bearing capacity of the retaining wall and significantly enhances the overall stability of the retaining wall.

The multiple horizontal support keels 8 and vertical support keels 9 are welded together in an intersecting manner.

[0027] The triangular support feet 4 provide excellent stability, and multiple support feet 4 enhance the stability and load-bearing capacity of the structure, resisting external loads and vibrations and ensuring the overall stability of the retaining wall. The anti-corrosion sleeves 5 made of zirconia ceramic have excellent high-temperature resistance and corrosion resistance, effectively preventing molten metal from eroding the flow steel holes 3 and extending service life. At the same time, multiple intersecting horizontal support keels 8 and vertical support keels 9 form a stable support frame, thereby enhancing the overall rigidity and stability of the retaining wall and resisting external loads and deformation.

[0028] The thermal insulation layer 10 has two layers, both of which are made of ceramic fiber board. The fireproof and flame-retardant layer 11 is made of rock wool board.
