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:
| number | parts name | material | heat treatment | note |
| 1 | chain plate | 65Mn | quenching HRC40 ~ 44 | flat pin stamping one time |
| 2 | pin | 40Cr | quenching HRC40 ~ 48 | |
| 3 | sleeve | 45 | quenching HRC40 ~ 46 | |
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.
