Tianjin Beyond Takes You To Understand The Installation Precautions Of Coal Bunker Liner
Coal bunkers for storing coal in coal mines, power plants and wharf industries are basically made of concrete. The surface is not smooth, the coefficient of friction is large, and the water absorption is high, which makes the coal bunker easy to bond and block, especially In the case of soft coal mining, more pulverized coal and high moisture content, the blockage accident is more serious. Especially in enterprises in northern my country, if the cold protection measures are not appropriate in winter, it is easy to cause the phenomenon of warehouse blockage caused by the freezing of moisture-containing materials and the warehouse wall.
The installation of the coal bunker lining board is to use the nails to fix the large plates on the warehouse wall. Generally, it is not necessary to cover the whole warehouse, as long as the coal discharge port of the lower conical section of the coal bunker and the upper round warehouse are lined with about 1 meter. That's it. During the installation of the coal bunker lining, the bolt countersunk head plane of the lining should be lower than the lining surface; the number of bolts used per square meter should be less than 10 during the installation of the lining of the coal bunker; the gap between the lining plates should not be Greater than 0.5cm (appropriate adjustments should be made according to the ambient temperature of the plate during installation).
When the coal bunker liner is installed for the first time, it needs to wait for the silo material to be stored to two-thirds of the entire silo capacity before unloading. In the process of use, keep the material entering and dropping point on the material pile in the warehouse to prevent the material from directly impacting the lining plate. Due to the different hardness particles of various materials, the material and flow rate should not be changed at will. If it needs to be changed, it should not be greater than 12% of the original design capacity. Any change of material or flow rate will affect the service life of the coal bunker lining.
