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.
