The company adheres to the service philosophy of integrity and is dedicated to the production of water-cooled screw conveyors

The water-cooled screw conveyor is a special conveying equipment that integrates conveying and cooling functions. The core lies in adding a circulating water cooling system on the basis of the traditional screw conveyor. Through both internal and external cooling structures, high-temperature bulk materials can be continuously conveyed in a closed environment, accurately cooled, and adapted to various high-temperature conditions. The following is an explanation from aspects such as core points, structure, principle, parameters, selection and application: Good sales volume, core definition and advantage definition: Also known as jacketed screw conveyor, it circulates in a closed cylinder/trough through the circulation of the jacket and the hollow screw shaft/blade. When exposed to cold water, it undergoes indirect heat exchange, simultaneously completing the transportation and cooling of high-temperature bulk materials. The feed temperature can reach 950℃, and the discharge temperature can be reduced to below 100℃. Excellent, core advantages: Integrated transportation and cooling, simplified process, reduced land occupation and energy consumption. It features a fully enclosed structure with excellent sealing performance and generates less dust, making it suitable for scenarios with high environmental protection and safety requirements. The area and water flow for controlling the discharge temperature when cooled can be flexibly adjusted. The helical blades and shaft materials are mostly made of split heat-resistant steel, which has low maintenance costs and a long service life. The working principle is that water enters the hollow helical shaft/blade through the rotary joint, while the outer jacket enters the circulating water, forming an internal and external cooling circuit. High-temperature materials entering the closed cylinder from the feed port. They are in full contact with the inner walls of the hollow blades, shafts and jackets. During the process of pushing the helical blades, heat is transferred through the metal walls. Encounter cold water. After absorbing heat, it meets cold water and is discharged from the other end, completing the heat exchange cycle, and the material is discharged. After reaching the target temperature due to cooling, it is discharged from the discharge port. The flow direction design of "water inlet at the outlet end and water outlet at the inlet end" is usually adopted to achieve counter-flow heat exchange. The actual effect mainly lies in the cooling efficiency. Applicable to industrial and material power: It is suitable for conveying unburned coal ash and high-temperature slag, and is convenient for handling when cooled. Metallurgy and chemical industry: Transport metallurgical furnace materials, gasification slag, high-temperature coke powder, etc., to meet the process temperature requirements. Building materials/mining: Transporting high-temperature clinker and slag, which is conducive to storage and transportation in the later stage when cooled. Others: High-temperature rubber powder, carbon black and other industrial bulk materials are conveyed when cooled. Key points for selection and maintenance: Select the core: Based on the material temperature, flow rate, cooling range and transportation distance, calculate the heat exchange area and water flow rate, and match the spiral diameter, speed and cooling circuit design. Regularly inspect the rotary joints to prevent water leakage. Monitor the quality and pressure of cold water to prevent scaling and blockage of waterways. Regularly inspect the wear of the spiral blades and replace the damaged parts in a timely manner. When the machine is shut down for a long time, the cold water needs to be drained to prevent cracking due to freezing or corrosion. Common application cases in thermal power plants: 950℃ slag is cooled to below 150℃, water flow is 5t////h, water pressure is 0.5MPa, suitable for subsequent transportation and treatment. Factory: Semi-coke powder at 450℃ is cooled to 80℃ both inside and outside. When cooled, the stability and safety of downstream equipment and materials should be confirmed.
