Description
Technical field
This utility model relates to part processing equipment technical field, specifically, relates to a kind of new-type roaster.
Background technology
Remanufacture part before carrying out impeller blasting, it is desirable to safe and environment-friendly, realize surface and oil contaminant efficiently
What state was serious remanufactures the thermal cleaning process of part, is put in roaster by the pending part that remanufactures,
Piece surface greasy dirt the distortion preventing part to the full extent and thermal deformation can be decomposed by roasting.
Existing roaster includes main chamber and auxiliary combustor, and the fuel gas buring process of main chamber produces
Flue gas enters auxiliary combustor abundant combustion decomposition further.Existing roaster is in roasting process, when main combustion
After burning the temperature value that indoor temperature reaches setting by heating, main burner can be cut off, ensuing guarantor
During temperature, after the temperature of main chamber is reduced to a certain temperature value, main burner can be rekindled heating
To improve temperature, in whole insulating process, main burner repeats cut-off and lights to reach to be incubated purpose；Auxiliary
Before temperature in combustor reaches the flue gas decomposition temperature set, auxiliary burner can keep high fire to carry rapidly automatically
High-temperature, after reaching set temperature value, auxiliary burner automatically switches into low fire to keep the temperature set.Roasting
After completing, roasting part naturally cool in roaster 100 DEG C and following after come out of the stove again.Existing roaster
In use there is following defect:
(1) existing roaster is in roasting process, and main chamber is heated to the insulating process after design temperature
In mainly by the repeated cutting of main burner with light and keep temperature, temperature controls inaccurate, main chamber
Actual temperature fluctuate within the specific limits, the most whole insulating process is not accomplished real constant temperature, no

Main burner repeats to cut off continually and light, it is easy to damages, reduces the service life of parts.
(2) roasting process there will be in main chamber the phenomenon that heating is uneven, local temperature differs, and
In existing roaster, temperature sensor is arranged on main chamber inner top, in the temperature of feedback main chamber
Time the temperature of its neighbouring pocket can only be fed back, control system controls main according to the temperature of feedback
Burner may cause the temperature in other regions to exceed or fall below the temperature value of setting, affects thermal cleaning effect.Separately
Outward, existing roaster after roasting completes, can only natural stove cold, rate of cooling is slower.(3) auxiliary burning
Room can keep a fixing desired temperature, so by cyclic switching height fire in part roasting process
And, in actual roasting process, the flue gas that main chamber is discharged can gradually decrease in insulating process, flue gas
After being reduced to a certain degree, auxiliary combustor just need not keep originally the highest design temperature again, and existing roasting
The auxiliary combustor burning stove sets constant high-temperature temperature, and the combustion gas adding auxiliary combustor to can not be along with main burning
Room enters the number of the flue gas of auxiliary combustor and regulates, and causes unnecessary gas energy to waste.
