(the second control valve 22 in conduction oil outlet 23 is to close to the first control valve 21 on control single chip computer opening heat conduction oil inlet pipe 13
), when filling the conduction oil of high temperature in each heating roller 1, close each the first control valve 21；
2) two motors 14 then, are opened, and the rotating speed of two motors 14 of regulation is consistent, then 5 add
Hot roller 1 is synchronized with the movement, and conveyer belt 7, lower conveyer belt 6 and upper conveyor belt 5 are rotated simultaneously in driving, and now, wood chip is from entering
Material mouth 16 enters in lower conveyer belt 6, and wood chip reaches the position being in contact with the outer wall of first heating roller with lower conveyer belt 6
When, wood chip carries out heat exchange with the high temperature heat conductive oil in heating roller 1：
3a, wood chip continue moved with lower conveyer belt 6, to first heating roller wood chip delivery outlet when, lower conveyer belt 6
Traffic direction is changed by positioning roll shaft 15, is fed forward, and wood chip enters in the presence of interior conveyer belt 7 from lower conveyer belt 6
On upper conveyor belt 5, i.e., second heating roller is entered from first heating roller, wood chip is with the conveying and the of upper conveyor belt
Two heating rollers are completed after heat exchange, then enter the 3rd conveyer belt by interior conveyer belt, are circulated successively with this and heating roller 1
Carry out heat exchange；
3b, ibid 3a steps, wood chip is after the 4th is heated roller (i.e. the N-1 heating roller) progress heat exchange, wood
Piece is entered in lower conveyer belt 6 by interior conveyer belt 7 from upper conveyor belt 5, and upper conveyor belt 5 is by positioning the side of change of roll shaft 15
Returned to and by driven wheels on the upper driving wheel 9-1 in first, top, start next circulation；
3c, at the 5th the wood chip that drying work is completed on roller (i.e. n-th heating roller) is heated with lower conveyer belt 6
Go out from the discharging opening 17 of the 5th heating roller side, meanwhile, by the dynamic action of heating roller 1, lower conveyer belt 6 is by driven
Wheel group returns to the feeding mouth 16 of first heating roller side, starts next circulation.

Oil, after filling it up with, each first control valve 21 carries out wood chip drying work, when the temperature being placed in first heating roller is passed
When sensor detects the temperature of conduction oil less than the temperature value set, controller will control the first control on the first heating roller
Valve 21, each second control valve 22 and each force (forcing) pump 20 are opened, then start the pattern of conduction oil circulation addition：That is high temperature heat conductive oil
Come out, gone out by entering the first heating roller after conduction oil efferent duct 12, heating roller from first again from the outlet of boiler 19
Roller is heated to enter second heating roller and then out enter the 3rd from second heating roller again, N is sequentially entered
After individual heating roller, temperature relatively low conduction oil is heated in conveying back boiler 19, is constantly circulated with this.
Compared with entering the heat conduction oil temperature of first heating roller, from the 5th heating roller (i.e. n-th heating rolling
Cylinder) outflow heat conduction oil temperature it is relatively slightly lower, conveying back boiler 1 heated.Therefore, by the device into heating roller 1
Send constantly into the conduction oil of high-temperature and reheat the conduction oil conveying back boiler 1 of low temperature, it is ensured that heating roller 1
Interior conduction oil is constantly in the condition of high temperature, so as to improve the drying efficiency of wood chip.
It is full based on the conduction oil just begun to warm up in roller 1, then is exported from boiler 19 and come out leading for how many high-temperature
Deep fat, then will how many low temperature conduction oil from recovery tube 25 flow into boiler 19 in.Therefore, it is not difficult to find out, provided with pan feeding
Conduction oil in mouthfuls 16 first heating roller in equipment operation, its internal heat conduction oil temperature on the whole highest and
N-th heating roller in heat conduction oil temperature it is relatively minimum, with it is undried processing, first enter into dry device when wood chip it is aqueous
Measure highest, the wood chip water content after N number of heating roller minimum corresponding.Therefore, the conduction oil in from 1 to N number of heating roller
Temperature is successively decreased successively, with the water content of wood chip with successively decreasing corresponding successively after dry, from without because temperature is too high
And dry wood chip to the situation of cracking, it is ensured that the dry mass of wood chip.
Explanation embodiments of the present invention are these are only, are not intended to limit the invention, for those skilled in the art
For, within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc. should be included in this hair
Within bright protection domain.
