鋼板倉如何分類以及有什么特點(diǎn)?如何延長壽命? How to classify steel plate silos and what are their characteristics? How to extend lifespan?通俗地說,凡是儲存散粒狀物料的圓筒狀構(gòu)筑物均可稱為倉,鋼板做的倉庫叫做鋼板倉。鋼板倉具有容納、儲存、裝卸、倒車等功能,具有平衡生產(chǎn)過程、確保持續(xù)生產(chǎn)、節(jié)省人力、提高機(jī)械化程度等作用。 Simply put, any cylindrical structure that stores granular materials can be called a warehouse, and a warehouse made of steel plates is called a steel plate warehouse. The steel plate warehouse has functions such as accommodating, storing, loading and unloading, reversing, etc. It has the functions of balancing the production process, ensuring continuous production, saving manpower, and improving mechanization. Steel plate silo is a modern and highly advanced and popular storage equipment, which is constantly expanding its application scope in the industry due to its various excellent properties. Suitable for industrial fields such as coal, steel, mining, building materials, chemical industry, and port environmental protection. Steel plate warehouses are roughly divided into three types: prefabricated steel plate warehouses, spiral steel plate warehouses, and welded steel plate warehouses. Prefabricated steel plate silo is a steel plate silo assembled by drilling steel plates in the factory and connecting them with high-strength bolts on site. Prefabricated steel plate silo has the following characteristics: The same specifications have lower strength and lower cost compared to other warehouse types; It can be assembled directly on site, with fast construction speed and low technical requirements for installation personnel; Removable, reassembled, and reusable; The use of high-strength bolts to connect steel plates results in relatively poor air tightness and is not suitable for storing powder materials and deteriorated materials. 2、螺旋式鋼板倉 Spiral steel plate silo
The spiral steel plate warehouse (also known as the edge rolling warehouse) uses the principle of "cold rolling and bending" to continuously refrigerate and bite the edges of laminated steel plates. Its structure determines that it can only be used for thin plates. The characteristics of the spiral steel plate silo are as follows:
Good sealing performance, can store various powdered and liquid materials such as cement, fly ash, food, etc.
Due to continuous cold bending and edge biting, the overall stability and safety have been improved (based on strong earthquake testing experience in various regions), and the service life is long.
Cannot be decomposed, can only be used permanently.
The technical requirements for on-site equipment operators are high, and the requirements for reel materials are high, which will narrow down the range of materials.
Compared to the same specification, the warehouse assembly requires a higher amount of steel, resulting in a corresponding increase in costs. Welded steel plate silo
Welded steel plate warehouse (also known as steel plate warehouse) is made of welded steel plates and is a large-scale welded steel plate warehouse independently developed by China in the continuous development of the steel plate warehouse industry. The welded steel plate silo has the following characteristics:
The warehouse has a large capacity, with a single storage capacity of 10000 to 100000 tons, which can form a larger storage group.
Compared with the spiral steel plate silo, the construction time is longer, the weight exceeds 2-3 times that of the spiral steel plate silo, and anti- corrosion treatment is required every 3-5 years. So, how to extend the service life of steel plate silos during use?
Regularly check whether the walls are deformed, pay attention to strengthening bolt connections, and if bolts are found to fall off, they should be filled in a timely manner.
After unloading the empty warehouse, it is necessary to confirm the sealing, whether the door frame and adjacent side panels are deformed, and whether cracks have occurred. If any abnormal situation is found, appropriate measures should be taken promptly. In addition, it is necessary to check whether there are any abnormalities in the connection part of the taper and take appropriate measures.
If welding deformation or welding cracks are found, the supply should be temporarily stopped to prevent unexpected situations from occurring. |
