Bucket conveyor,Its material is Q345 and Q235,for the CFB boiler:
Bucket conveyor:
Features:
1, Bucket slag machine adopts special heavy high strength double row plate chain, single row limit tensile load of 39.2 t, operation is stable and reliable; All parts of the heat treatment of the chain, chain plate hole for the flat hole, pin two sides milling flat, no relative rotation after assembly, make it to zero wear, greatly improving the service time.
Main material and heat treatment requirement see the table below:

2, External type roller, fitted with double row rolling bearing, the lateral equipped with pressure oil cup, easy to change.
3 ,Sprocket using disc type structure, the machine maintenance changed quickly.
4, Chain installed in bearing, small friction, flexible operation, low noise,improve the service time.
5, It is harmful if the length of the chain is differ and the binding is common problem, the length of two rows of chain differ is harmful binding, will cause the noise increased sharply, chain springing, distortion, fracture, chain wheel wear a sharp increase in motor overload and so on all sorts of problems; Bucket slag tail department two sprockets with double bearing empty on the shaft,it can free rotation, respectively, to avoid the linkage, produced harmful when two row differ long chain;
6, Tail adopts spiral spring tensioning device, not only adjust the drag chain tensioning degree automatically, also when it stop, it effectively buffer by the rapid changes in load effects;
7, Using knapsack transmission mechanism, save the scene space, installation is simple;
8, To save space and ensure the neatness of the environment, slag machine interior part can be decorated in zero meters, the part can adding seal cover above zero meters;
9, To facilitate the watch chain bucket the operation situation of slag machine, in a closed chain bucket set appropriate slag machine two sides of the gate number of observation, observation door is open quickly.
