Continuous inspection and maintenance.
The utility model is further arranged to: the connecting column is located at blind hole clearance fit.
By using above-mentioned technical proposal, connecting column can be directly inserted into blind hole, and gap is minimum therebetween, energy
The vibration occurred in operational process is enough effectively reduced.
The utility model is further arranged to: the stomata is obliquely installed；
The stomata is lower than the other end close to one end of slanting baffle.
By using above-mentioned technical proposal, when cold air is sprayed from stomata, the angle between slanting baffle is smaller, flow velocity damage
It loses small, higher flow velocity can be obtained.
The utility model is further arranged to: wear-resistant coating is coated on the upper surface of the horizontal baffle and slanting baffle.
By using above-mentioned technical proposal, spraying ceramic coat or diamond coatings, energy on horizontal baffle and slanting baffle
It is enough to reduce abrasion, improve the service life of the two.
In conclusion the advantageous effects of the utility model are as follows:
1. after cold air enters cavity in the utility model, into the acceleration for crossing cavity, being sprayed from stomata, then along oblique
Baffle and horizontal baffle lead into the bed of material, and level is discharged after moving on to one end distance in the bed of material.Cold air exists during being somebody's turn to do
Residence time is long in the bed of material, can take away a large amount of heat, reduce rapidly material layer temperature, treatment effeciency greatly improves.
2. the column in the utility model on horizontal baffle bottom surface is directly inserted in the blind hole in protrusion, this connection type
Simply, the probability of damage is low, will not fail under prolonged hot operation.And it, can not in subsequent maintenance process
Directly horizontal baffle is removed by tool, simplifies maintenance process.
3. the utility model increases column on the bottom surface of flat baffle, as its support between plate, Neng Gouyou
Effect avoids flat baffle from being bent.
