TGSS scraper conveyor
The scraper conveyor is a continuous transportation equipment that transports scattered materials by means of a moving scraper chain in a closed large cross-section shell; Since the scraper chain is buried in the material when transporting the material, this is the reason why it is called the scraper conveyor. This series of buried scraper conveyor products have the characteristics of simple structure, good sealing, convenient installation and maintenance, and flexible process layout. Burial scraper conveyor products can not only transport horizontally, but also tilt or vertical transport; It can be used either individually or jointly; Can add more, can also unload more.
1, buried scraper conveyor is often used for horizontal transport of particles and powdery materials, but also can be inclined to transport within a range of 150 °;
2, buried scraper conveyor has the characteristics of high life span, smooth operation, small structure size, large amount of transportation, low energy consumption, and low material damage rate;
3, the structure of the buried scraper conveyor is reasonable, and it can be added more points. The speed of the scraper's movement is under the transmission of the reducer, and the operation is stable and the noise is low. On the basis of a single point of entry and exit material, it is also possible to add more points. It has outstanding features in transporting toxic, explosive, high-temperature and fly-away materials, improving workers 'operating conditions and reducing environmental pollution.
The coal is continuously exported through friction between the moving chain scraper and the coal in the closed hull. Chain scraper The conveyor that is buried in the coal to be transported and fixed on the traction chain during operation. The traction chain and scratch plate of this conveyor are buried in the material. The scratch plate only occupies part of the section of the material slot, and the material accounts for most of the section of the material slot. It can carry materials horizontally, obliquely or vertically. When transporting horizontally, the scraper used is in the shape of a flat strip. The principle that the cutting force of the loose layer is greater than the resistance of the groove wall to the loose layer by the chain and the scratch plate embedded in the loose material, so that the loose material moves forward with the scratch plate. At this point, the ratio of the height of the moving material layer to the width of the slot is within a certain ratio range, and the material flow is stable.
(1) When the buried scraper conveyor is transported horizontally, the material is affected by the pressure of the scraper chain in the direction of movement and the weight of the material itself, and internal friction is generated between the materials. This friction ensures the stability of the material layer and is sufficient to overcome the external friction caused by the movement of the material in the slot, so that the material forms a continuous whole material flow and is transported.
(2) When the buried scraper conveyor is lifted vertically, the material is subjected to the pressure of the scraper chain in the direction of movement, and the lateral pressure in the material is generated, forming the internal friction force of the material. At the same time, due to the continuous feeding of the lower level, the lower part of the material has successively generated a push force on the upper part of the material. This friction force and push force are sufficient to overcome the external friction resistance and the weight of the material generated by the movement of the material in the slot, so that the material forms a continuous whole material flow and is raised.
