Description

TECHNICAL FIELD

[0001] The utility model discloses a steel plate storehouse, especially relates to spiral steel plate storehouse, belongs to the technical field of silo. BACKGROUND

[0002] The spiral steel plate warehouse is a modern warehouse facility, which is formed by special equipment to continuously spiral interlocking steel plates without welding or bolt connection, and can greatly shorten the construction period. The continuous and airtight layer formed by spiral interlocking can effectively isolate air and moisture, prevent material oxidation and mold, and generally uses high-strength galvanized steel plates (thickness 1-6mm) to make, which has good weather resistance and a service life of 25-30 years. Based on its outstanding advantages, it has a wide range of applications, such as grain and feed storage (insect and mold prevention) in agriculture, cement, fly ash, and mineral powder storage (moisture and caking prevention) in industry, sewage treatment sludge and biomass particle treatment warehouse in environmental protection, and bulk material storage such as coal and coke in energy steel production. In many application scenarios of spiral steel plate warehouses, there is corrosion, for example, desulfurization ash has corrosive properties to the steel plate of the steel plate warehouse, so the inner wall of the steel plate warehouse needs to be corrosion-resistant when storing such materials. There are mainly two ways to achieve corrosion resistance of the spiral steel plate warehouse: one is to directly use corrosion-resistant materials to make the spiral warehouse wall, such as Chinese patent CN118145187A (Spiral interlocking steel plate warehouse for storing corrosive medium and method for manufacturing the same), which needs to use special and special corrosion-resistant plate materials, and the cost is generally high. The second is to still use the current steel plate to make the warehouse wall, and then make a corrosion-resistant layer on the inner wall after the spiral interlocking steel plate warehouse is completed. Some simple corrosion-resistant coatings are brushed on the corrosion-resistant layer, which has poor durability. For many occasions, a popular mode for making a corrosion-resistant layer is as follows: first, apply hot asphalt (primer) to the inner wall of the warehouse, then stick a layer of mesh (cloth) when the asphalt viscosity is relatively large, such as using glass fiber cloth (mesh), and then make a subsequent corrosion-resistant layer. Since the mesh (cloth) is attached to the inner wall of the warehouse, it can stably support the coating layer for a long time to achieve corrosion resistance. For example, in the case of the corrosion-resistant layer of the spiral steel plate warehouse for storing desulfurization ash, the subsequent corrosion-resistant layer is made by applying a second layer of coating (usually polyurethane coating) after the first layer of glass fiber cloth (mesh) is dried, and then applying a second layer of glass fiber cloth (mesh) when the second layer of coating is not dry. After the second layer of glass fiber cloth (mesh) is dried, a third layer of coating (such as epoxy resin coating) is applied. In the storage of desulfurization ash, this corrosion-resistant layer can be used for more than 6 years, although it has strong corrosion resistance, but it still lags behind the design life of the steel plate warehouse. When the existing corrosion-resistant layer of the steel plate warehouse is damaged, it needs to be reprocessed. In the study of the damage of the existing corrosion-resistant layer of the steel plate warehouse, it is found that the main cause of the damage of the corrosion-resistant layer with this structure is the partial shedding of the first layer of glass fiber cloth (mesh) caused by the friction and impact of the material during use, which in turn causes the corrosion-resistant layer to be damaged. Therefore, how to form a more durable corrosion-resistant layer is a problem that needs to be solved in the development of spiral interlocking steel plate warehouses. SUMMARY

[0003] The utility model discloses a kind of anticorrosive spiral bite steel plate storehouse wall structures to overcome the above-mentioned problems existing in current anticorrosive spiral bite steel plate storehouse.

[0004] To achieve the purpose of the utility model, the following technical solutions are adopted: an anticorrosive spiral bite steel plate storehouse wall structure, the steel plate storehouse is a spiral steel plate storehouse, the wall is composed of multiple layers of metal plates spirally rising, the upper metal plate and the lower metal plate are connected by bite engagement, a layer of metal or non-metal mesh is arranged on the inner wall of the storehouse, the mesh is fixed in the bite of the upper metal plate and the lower metal plate, and a subsequent anticorrosive structure is made on the wall with the mesh.

[0005] Further, the mesh is engaged in all bites, and the mesh and the metal plate have the same spiral shape.

[0006] Further, the mesh between the upper and lower adjacent two bites is in a tension state after being engaged.

[0007] The utility model has the following beneficial technical effects: in the structure, the mesh is directly engaged in the bite between the upper plate and the lower plate of the steel plate storehouse, has good integrity with the steel plate storehouse, is not easy to deform and fall off, the wear resistance and impact resistance of the anticorrosive structure are better than those of the structure in which the mesh is bonded on the inner wall of the steel plate storehouse, and the service life of the anticorrosive structure formed by the wall is correspondingly prolonged.

[0010] To more fully explain the implementation of the utility model, an implementation example of the utility model is provided. These implementation examples are only an illustration of the utility model and do not limit the scope of the utility model.

[0011] The utility model is further explained in detail in combination with the drawings, and the marks in the drawings are as follows: 1: outer wall of steel plate storehouse; 2: bite; 3: mesh.

[0012] The spiral steel plate storehouse in the application has many ready-to-use applications in industry and agriculture, and its structure and construction method are all prior art. The mesh in the application refers to cloth or mesh. The cloth is relatively dense, and the mesh is relatively larger than the cloth hole. For example, the widely used glass fiber cloth, of course, can also be other cloth meshes, such as carbon fiber cloth, basalt fiber cloth, stainless steel mesh, high-density polyethylene cloth, etc.

[0013] As shown in the drawings, the anticorrosion spiral bell and spigot steel plate warehouse wall structure, the steel plate warehouse is a spiral steel plate warehouse, 1 is the outer wall of the steel plate warehouse, the warehouse wall is composed of multiple layers of metal plates spirally rising, the upper layer of metal plates and the lower layer of metal plates are connected by the bell and spigot 2, a layer of metal or non-metal mesh cloth 3 is arranged on the inner wall of the warehouse, the mesh cloth 3 is fixed in the bell and spigot 3 of the upper layer of metal plates and the lower layer of metal plates, and the subsequent anticorrosion structure is made on the warehouse wall provided with the mesh cloth. The mesh cloth is engaged in all the bell and spigots, and the mesh cloth and the metal plates are spirally arranged. The mesh cloth between the upper and lower adjacent two bell and spigots is in a tension state after being engaged.

[0014] The mesh cloth is engaged in the bell and spigot, which is easy to realize when the spiral steel plate warehouse is built. The mesh cloth roll and the steel plate roll can be fed at the same time when the warehouse is built (the mesh cloth can be adhered to the steel plate by using adhesive tape at the front end to facilitate feeding), so that the mesh cloth is located inside the steel plate. When the mesh cloth passes through the bell and spigot making equipment, the mesh cloth is engaged in the bell and spigot. The mesh cloth can also be directly arranged in two layers with the steel roll when the steel roll is unwound, so that the mesh cloth and the steel plate are fed synchronously when the steel plate is fed. The mesh cloth is engaged in the entire bell and spigot.

[0015] In the present application, the subsequent anticorrosion structure can be designed and constructed according to the specific use of the steel plate warehouse. For a desulfurization ash warehouse, a layer of asphalt is first coated on the inner wall of the warehouse with the mesh cloth, and then polyurethane paint is coated after drying. The second layer of glass fiber cloth (mesh) is adhered when the polyurethane paint is not dry. The paint (such as epoxy resin paint) is coated after the second layer of glass fiber cloth (mesh) is dried. According to different use occasions, a layer of asphalt is first coated on the inner wall of the warehouse with the mesh cloth, and then the epoxy resin paint is directly coated on the asphalt.
