product overview

Buried scraper conveyor series products are widely used in metallurgy, building materials, electricity, chemicals, cement, ports, docks, coal, mining, oil, grain, food, feed, industries and sectors. Buried scraper conveyor is a kind of continuous transport equipment which in the giant closed section shell, with the aid of the movement of the chain scraper to transfer bulk material. Because when conveying material, scraper chain all buried in the material, so it is called buried scraper conveyor. This machine structure is simple, good sealing, easy installation and maintenance, process arrangement flexible; It can not only level conveying, also can tilt and vertical transportation; Not only can use single, also can use a combination of many sets; Can multipoint charging, also can multipoint discharging. Due to shell is closed, so in conveying great, toxic, explosive, high temperature material can dramatically improve the workers’ work environment and prevent and control environmental pollution. Buried scraper conveyor is a kind of conveying material system equipment, favorably welcomed by metallurgy, mining, power.

product features

1. Buried scraper conveyor often used for granular level transporting particles and powder materials, also can be in 150 ° angle range for tilt transportation;

2. Buried scraper conveyor has the long life, smooth operation, structure of small size and large amount transportation, low energy consumption, material damage rate low characteristics;

3. Buried scraper conveyor structure reasonable, can multipoint

charging, scraper movement speed with reducer’s drive, smooth operation, low noise, in the basis of single point in and out of the material, can also multipoint feeding, multipoint out of material, it has outstanding characteristic for transporting toxic, explosive, high temperature and easy to float in the sky of materials, improve workers’ conditions and reduce the pollution of the environment.

Buried scraper conveyor’s working principle:

 in a closed cabinet with moving chain scraper and coal friction output the coal continuously, when operating the chain scraper is buried in the coal, the scraper fixed in the chain in closed tanks conveying bulk material. Both the chain and scraper are buried in the materials, scraper accounts for only part of the slot section, and the material accounts most of the slot section. It can level, tilt or vertical transport materials.Level conveying, use flat scraper bar, use the principle of the chain buried in bulk material of and the scraper cutting ability to the slabs of bulk material layer more than resistance of tank wall to bulk material, make the bulk material with scraper move forward together, and at the time the scale of material layer’s height and tank’s width is in a certain range, the material flow is stable.

1. Level conveying , material get pressure of scraper chain in the direction of the movement and its own weight in the material produce internal friction. The friction ensures the stable state between material layer, and enough to overcome the outside friction cased by material’s movement in the slot, make the material form a continuous and whole flow to be transported.

2.,Buried scraper conveyor in vertical ascension, material get pressure by scraper chain in direction of motion, in the material produced the side pressure of horizontal direction, formed the material’s internal friction. At the same time because of constant feeding below, the lower material produce thrust to the upper material. The friction and thrust are enough to overcome the friction resistance caused by material move in slot and material’s own weight, make the material form a continuous and whole flow to be lifted.
