Screw conveyor is a commonly used material conveying equipment, widely used in various industrial fields, such as food, chemical industry, construction, metallurgy and other industries. With its unique structural design and efficient conveying capacity, it provides convenient material conveying solutions for various industries. 1. Working principle of screw conveyor The working principle of the screw conveyor is to use the rotation of the spiral blades to push materials from the entrance of the conveyor to the exit. The spiral blade is usually installed in a cylindrical casing, and the motor drives the spiral blade to rotate to achieve continuous transportation of materials. During the conveying process, the material is affected by the thrust and friction of the spiral blades, causing it to advance along the axis of the conveyor. 2. Structural characteristics of screw conveyor 1. Spiral blade: The core component of the screw conveyor. Its material and shape directly affect the conveying effect and the service life of the equipment. Spiral blades are usually made of high-strength, wear-resistant materials, such as stainless steel, carbon steel, etc. 2. Chassis: used to accommodate materials, usually cylindrical, used in conjunction with spiral blades to keep materials stable during transportation. 3. Driving device: including motor and reducer, used to drive the spiral blades to rotate. The motor usually uses a reduction motor to meet the conveying speed requirements under different working conditions. 4. Support device: used to support the entire conveyor to ensure its stability and safety during operation. 5. Control system: used to control the start, stop, speed adjustment and other functions of the screw conveyor, which can be selected according to user needs. 3. Application fields of screw conveyor 1. Food industry: used for mixing, conveying, measuring, etc. of materials, such as conveying flour, milk powder, sugar and other powdery materials. 2. Chemical industry: used for transporting toxic, flammable and explosive materials, such as pesticides, fertilizers, chemical raw materials, etc. 3. Construction industry: used for conveying concrete, mortar, stone and other building materials. 4. Metallurgical industry: used for transportation, selection, grinding and other operations of metal minerals. 4. Advantages of screw conveyor 1. Simple structure: The screw conveyor has a compact structure, is easy to install and maintain, and occupies a small area. 2. High conveying efficiency: The screw conveyor adopts continuous conveying method, which is highly efficient and saves manpower and material resources. 3. Strong adaptability: The screw conveyor can adapt to the transportation of various materials and can meet the requirements of different working conditions. 4. Safety and environmental protection: The screw conveyor adopts a closed structure, which effectively reduces material leakage and reduces environmental pollution. 5. Things to note when selecting screw conveyors 1. Select the appropriate screw conveyor type based on the nature, shape, viscosity and other factors of the material. 2. Consider the conveying distance and height to determine the casing length and diameter. 3. Select the appropriate driving method and motor specifications to ensure stable operation of the conveyor. 4. Pay attention to the material and anti-corrosion performance of the conveyor to meet the requirements of different working conditions. 5. Consider the control system and safety protection devices of the conveyor to ensure the safety of equipment operation. In short, as an efficient material conveying equipment, screw conveyor plays an important role in various industries in our country. During the purchase and use process, it is necessary to fully understand its working principle, structural characteristics, application fields and selection precautions to ensure efficient, stable and safe operation of the equipment.
