Hazardous chemicals possess characteristics such as flammability, explosiveness, and toxicity. The construction of automated stereoscopic warehouses that meet explosion-proof standards has become a rigid requirement for chemical enterprises to achieve compliant operation, safe production, and high-efficiency development. Our current case is from the chemical industry, and the client is a leading enterprise in the hazardous chemicals supply chain. The company provides one-stop logistics and supply chain services for chemical enterprises. In recent years, it has focused on developing chemical product trading business, operating categories such as chemical coatings, alcohol-based fuels, phosphorus chemicals, and gas stations through a self-operated model. In response to project requirements and the characteristics of the client’s products, this project mainly refers to the GB 3836 series standards. The explosion-proof grade of the equipment used is Ex IIC T4, which can meet the explosion-proof requirements for products such as hydrogen and acetylene, as well as the explosion-proof requirements for products with an ignition temperature of 135℃-160℃. Equipment in the project, including explosion-proof stacker cranes, explosion-proof conveyors, and explosion-proof electrical cabinets, is all designed and constructed in accordance with the Ex IIC T4 explosion-proof grade and requirements, and has passed explosion-proof certification. All automated equipment adopts explosion-proof motors, explosion-proof wireless communication, and a safe power supply system, and is strictly designed in compliance with national explosion-proof electrical design standards. The power supply method for the stacker cranes uses a towline power supply technology with sealed cable conductors, which not only achieves explosion-proof performance but also reaches an IP65 protection rating (for water and dust).
