MGB type buried scraper conveyor

MGB embedded scraper conveyor is used for conveying dry ash underneath electric precipitators of coal-fired power plants. Its structure and performance is as follows. It is equipped with a scraper driven by a single ring chain, a concave tooth-shaped drag sprocket, a supporting roller-supported return chain, a self-tensioning chain, a worm gear, a manual tensioning transmission, cast stone lining and a knapsack drive mechanism. After long-term operation, it has been proved a well-received innovative product among similar devices at present. 

Model MGB410×L: 410 indicates that the scraper is 410mm wide and L represents the maximum conveying distance m of the equipment. 

See the figure attached for the structure and installation dimensions of MGB410xL conveyor. 

The scraper is driven by a single high-strength mining ring chain (①22×86) and a concave tooth-shaped drag sprocket is employed. The chain has a significantly large load capacity, long service life and excellent operation reliability. 

In addition to saving labor and reducing wearing, the supporting roller-supported return chain and the scraper can also make the chain self-tensioned through the return chain along with the natural increase of the deflection among several supporting rollers. When the deflection of the return chain goes beyond the limit, the simple and labor-saving manually operated worm is used for continued tensioning. 

As feeding ash is shunted, the return chain is separated from the scraper and ash, thus preventing chain blockage and scraper accidents due to sudden increase of feeding ash and its filling in the bin. As the bin bottom and side wall is lined with 50mm-thick cast stone, they are wear-resistant and heat-preserving. 

The drive mechanism is over the upper part of the conveyor head and integrated with the housing. Foundation bolts are not required as the whole conveyor is freely placed on the platform. 

 

Please select the ash conveyor of corresponding specifications according to the requirements of output and conveying distance and relevant conditions, and indicate the position of the feed port and the elevation and dimensions of the flange. In case of any special requirement, please contact us.
