Conveyor is a kind of automatic transportation machinery and equipment that continuously conveys materials on a certain line and within a certain distance. The weighing screw conveyor is a metering and conveying device that uses a spiral pipe to continuously convey materials, and dynamic weighing can also be carried out during the conveying process. It is widely used in building materials, chemical industry, electric power, metallurgy, grain, cement and other industries because of its excellent performance and diversified functions. It is suitable for horizontal conveying of powdery, granular and small block materials, such as coal mines, ash, slag, cement and grain.
The weighing screw conveyor has the following advantages:
1. Efficient material transportation: The spiral body with small diameter, high speed and variable pitch design is equipped with steady flow technology to ensure smooth, fast and uniform material transportation.
2. Flexible layout and displacement: The overall structure of the conveyor is exquisite, which can make full use of the installation space for installation, and the installation and displacement are convenient.
3. High durability: The shell of the conveyor is made of high-quality seamless steel pipes and connected by flanges to form an integral fuselage structure. The overall fuselage structure is rigid, and the overall durability is relatively strong.
4. Sealed conveying without leakage: The spiral pipe adopts a unique sealing structure to prevent leakage, protect the material characteristics in the spiral pipe from being changed, and keep the site environment clean.
5. Realize dynamic continuous measurement and automatic control: by combining dynamic continuous weighing with conveying mode, automatic weighing is realized in the conveying process. The conveyor is combined with PLC to achieve quantitative control of materials.
Weighing screw conveyors have the following application shortcomings:
1. The scope of application is limited: the conveying capacity is limited, and it is not suitable for the transportation of particularly large quantities of materials; It is not suitable for some materials with strong viscosity, excessive particles and large blocks. Some materials with high humidity, high viscosity and easy agglomeration are also more likely to cause blockage.
2. Difficult to clean and maintain: The overall structure of the conveyor is relatively complex, and it may be difficult to clean and maintain, especially inside the spiral.
3. High cleanliness of materials is required: if the feed contains hard and large debris, it may cause damage to the spiral blades, damage to the equipment, and suspension of production and conveying materials.
