Spring Frameless Action Scraper conveyor is divided into MS, MC, MZ, MGS and other series! Buried scraper conveyor is a kind of transportation equipment that continuously conveys bulk materials with the help of a moving scraper chain in the shell of a closed rectangular section, because in the conveying process, the scraper chain is buried in the conveyed material, so it is called "buried scraper conveyor".
When the buried scraper conveyor is conveyed horizontally, the material is affected by the pressure of the scraper chain in the direction of movement and the weight of the material itself, which generates internal friction between the materials. This friction ensures the stable state between the material layers, and is enough to overcome the external friction caused by the movement of the material in the machine tank, so that the material forms a continuous overall material flow and is conveyed.
When the buried scraper conveyor is lifted vertically, the material is subjected to the pressure of the scraper chain in the direction of movement, which generates the lateral pressure in the horizontal direction in the material, forming the internal friction of the material. At the same time, due to the continuous feeding of the lower horizontal section, the lower material successively produces a pushing force on the upper material. This friction and pushing force are enough to overcome the external friction resistance caused by the movement of the material in the machine groove and the weight of the material itself, so that the material forms a continuous overall material flow and is lifted.
Buried scraper conveyor series products are widely used in metallurgy, building materials, electric power, chemical industry, cement, ports, docks, coal, mining, grain and oil, food, feed, and other industries and departments. The buried scraper conveyor is a kind of continuous transportation equipment that conveys bulk materials with the help of a moving scraper chain in a closed giant cross-sectional shell; Because when conveying materials, the scraper chain is all buried in the material, it is called a buried scraper conveyor. The machine has simple structure, good sealing, convenient installation and maintenance, and flexible process layout; It can not only be conveyed horizontally, but also inclined or vertically; It can be used as a single machine or as a combination of multiple units; It can be multi-point feeding and multi-point discharge. Because the shell is closed, it can significantly improve the working environment of workers and prevent environmental pollution when conveying large, toxic, explosive and high-temperature materials. The buried scraper conveyor is a popular material conveying system equipment for metallurgy, mining and thermal power plants.
Product features: the buried scraper conveyor has a simple mechanism, light weight, small size, strong sealing, and is convenient for installation and maintenance; It can not only convey horizontally, but also tilt or vertical lifting; It can be multi-point feeding and multi-point unloading, and the conveyor process layout is more flexible. Because the shell is closed, it has more prominent advantages in improving the operating conditions of workers and preventing environmental pollution when conveying easy-to-fly, toxic, explosive and high-temperature materials.
1. The buried scraper conveyor is often used for horizontal conveying of particles and powdery materials, and can also be used for inclined conveying within the range of 150° angle;
2. The buried scraper conveyor has the characteristics of high service life, stable operation, small structure size, large conveying capacity, low energy consumption and low material damage rate;
3. The structure of the buried scraper conveyor is reasonable, it can be multi-point feeding, the moving speed of the scraper is under the transmission of the reducer, the operation is stable, the noise is low, and on the basis of single-point feeding and discharging, it can also be fed at multiple points and discharged at multiple points, which has outstanding characteristics in conveying toxic, explosive, high-temperature and easy-to-fly materials, improving workers' operating conditions and reducing environmental pollution.
What are the main parts of the scraper?
The scraper conveyor is mainly composed of the head, tail, middle groove, scraper chain and other components.
1. The head transmission part (machine head) is composed of the head frame, motor, coupling (coupling), reducer and sprocket assembly, derailleur, guard plate, etc.
2. The middle part is composed of a transition groove, a middle groove, a chain, a scraper, a beam, a bolt, a dumbbell pin and so on.
3. Tail (transmission part): tail sprocket assembly, derailleur, guard plate, etc.
The scraper conveyor can be horizontal, inclined, vertical and other forms according to the working conditions. The material has characteristics such as internal friction and side pressure. When transported horizontally, the material is subjected to the thrust of the scraper chain in the direction of movement, so that the material is squeezed, due to its own weight, the internal friction force is produced between the materials, and this internal friction ensures the stable state between the material layers, when it is greater than the external friction between the material and the groove wall, the material forms a continuous overall material flow and is conveyed forward with the scraper chain.
When lifting vertically, due to the supply characteristics of the material, after the material is pushed by the scraper chain in the direction of movement, the lateral side pressure is generated in the material, forming the internal friction of the material. At the same time, the continuous feeding of the lower horizontal section produces a pushing force on the upper material, forcing the material upward, when these forces are greater than the external friction between the material and the groove wall and the weight of the material itself, the material forms a continuous overall logistics and is lifted. Because of the vibration in the movement of the scraper chain, the material arch will sometimes be damaged and sometimes formed, so when the vertical transportation, the material will produce a hysteresis phenomenon relative to the chain, which has a slight impact on the conveying efficiency and speed, but does not hinder the normal operation.
