Description
Technical field
A kind of cement clinker cooler comb board roof beam ash-clearing structure is the utility model is related to, particularly a kind of torsional mode grate plate
Beam online ash removal structure.
Background technology
Grate cooler used in cement plant, its comb board roof beam can all be caused in beam inner product clinker ash due to following two reason：
(1) there is certain installation gap between grate plate and grate plate, can be leaked in ash to comb board roof beam by the gap；(2) inside by grate plate
Ventilation comb seam leakage ash in comb board roof beam.Moreover, as grate plate use is longer, installation gap and ventilation comb seam due to abrasive action
What can be become is increasing, so as to cause leakage ash also increasingly severe, and when dust stratification seriously to when influencing air feed, it is necessary to by cooler
Stop and carry out deashing, then can start cooler normal operation.
Cement plant solves the problems, such as that deashing mainly uses following two methods at present：
1. as shown in Figure 1, circular hole (or the other forms of one or more a diameter of d are opened on the bottom plate of comb board roof beam 101
Hole), the hole opened is blocked again after internal dust stratification is vented.
2. as shown in Fig. 2, circular hole (or the other forms of one or more a diameter of d are opened on the bottom plate of comb board roof beam 101
Hole), while the cover board 201 (or lid of other shapes) for increasing a diameter of D covers the ash removing opening on comb board roof beam, cover board 201 passes through
Screw 202 and comb board roof beam 101 couple.
Although above two purge mode structure is all very simple, all there are one it is common the shortcomings that：Cooler must all stop
After only running, it is manually entered inside cooler and carries out deashing, and the examination that the running rate of cement plant production line is important as one
Index, the out of service of cooler will directly result in whole firing production line and all stop (cement plant is commonly called as " stopping kiln "),
This can seriously affect the running rate of production line.
Utility model content
