Flue chamber 8 is connected with lower flue chamber 9 by several heat exchanging pipes 7, and upper flue chamber 8 is separated into 10 He of smoke input chamber by partition board 5
Smoke output chamber 11, a part of heat exchanging pipe 7 are connected to smoke input chamber 10, and remainder heat exchanging pipe 7 is connected to smoke output chamber 11, combustion furnace 1
Exhanst gas outlet is connected with smoke input chamber 10 (heating agent entrance), and smoke output chamber 11 (heating agent outlet) is connected with the air inlet of induced-draft fan 12
It is logical；The cavity 3 is cone-shaped hood 13 at heat outlet.The cone-shaped hood 13 passes through air-heater blast pipe 14 and air-heater 15
Air inlet is connected.The air outlet of air-heater 15 is connected with the hot air inlet 26 of drying tower.
Inlet Network 16 is respectively provided at the cold air inlet of the combustion furnace 1 and heat exchanger 2, the Inlet Network 16 of setting is in order to anti-
Only the flammable sundries outside combustion apparatus enters the outer surface of heat exchanging pipe 7 in combustion furnace 1 and heat exchanger 2, after-combustion of being heated, into
Enter drying tower；If the first flame screen of arterial highway 17 is arranged in heat exchanger 2, especially by following manner：The side of the heat exchanger 2 has
There are opening AB, the first flame screen 17 to be inserted into flame screen positioning plate 23 from opening AB, fixed by flame screen positioning plate 23
In heat exchanger 2, there is sealing plate 24, sealing plate 24 and the outer surface of heat exchanger 2 to be tightly connected at the AB that is open.It is handed in heat exchanger
If the first flame screen of arterial highway 17 is arranged in the thermal current passway after changing, the minimum cross-section that protection network is located at cone-shaped hood 13 (changes
The heat outlet of hot device) between heat exchanging pipe 7, to ensure planar shaped the first flame screen 17 area be more than air-heater into
The sectional area of air hose 14, to reduce the failure that the first flame screen 17 is quickly blocked by sundries；The first flame screen 17 being arranged be for
Prevent in the positions use such as combustion furnace 1 and heat exchanging pipe 7 cracked, the spark carried secretly in combustion product gases passes through air-heater 15
Into drying tower, dry paddy is caused to burn.
It is penetrated in the heat exchanger 2 and cleans brush holder support 19, the inner end for cleaning brush holder support 19 is equipped with cleaning brush 20, cleaning brush 20
Hairbrush is prevented for periodically clearing up the sundries on 17 surface of the first flame screen because sundries is excessive close to the first flame screen 17
Caused by the first flame screen 17 by the generation of sundries stopping state.Meanwhile being provided with sediment flushing outlet, sediment flushing outlet on the heat exchanger 2

In addition, the second flame screen 27 is arranged at the hot air inlet 26 of drying tower, when preventing heat exchanger 2 from splitting, in cigarette
Spark enter drying tower 25, if in production if heat exchanger exchange after thermal current passway in be arranged the first flame screen of arterial highway
17, so that it may not have to that the second flame screen 27 is arranged on drying tower 25；If the second flame screen 27 is arranged on drying tower 25, just
The first flame screen 17 of setting can not be had to；27 this feelings of first flame screen 17 and the second flame screen can certainly be set simultaneously
Condition.
Working principle of the present invention is as follows：When rice drying machine works, fuel burns in combustion furnace 1, the cigarette after burning
Gas enters the smoke input chamber 10 of heat exchanger 2, moves downward across heat exchanging pipe 7, into lower flue chamber 9, and moves backward, flue gas is again
It is secondary to move upwards, subsequent heat exchanging pipe 7 is passed through, is discharged in air into smoke output chamber 11 into induced-draft fan 12；It is a part of cold
Air-flow wears the outer wall heating of the combustion furnace 1 of the encirclement of Inlet Network 2, and a part of cold airflow is passed through the air inlet of 2 side of heat exchanger
Net 2 enters between heat exchanging pipe 7, is heated to cold airflow by the outer wall of heat exchanging pipe 7, and the hot gas of heating enters by air-heater 15
Rice drying tower.
When there is the hole burnt out inside heat exchanger 2, the first flame screen 17 of setting can be stopped effectively from burning out
The flue gas escaped from of hole in Mars enter the failure that drying tower causes paddy to burn；If the first flame screen 17 does not stop cigarette
Mars in gas, Mars alarm sensor 21 can detect the Mars carried secretly in hot wind, and alarm signal is sent out by controller；
The Inlet Network 16 gone out in 2 air inlet of heat exchanger is set, inflammable sundries can be stopped and entered in heat exchanger 2, to prevent in heat exchanging pipe 7
High-temperature baking under these inflammable sundries burnings, and enter drying tower with hot wind；The wind pressure sensor 22 of setting can perceive
After the first flame screen 17 is by sundries Severe blockage, the case where subsequent wind pressure of the first flame screen 17 declines, to pass through control
Device sends out alarm, the sundries of the first flame screen 17 is cleared up in time, to improve the thermal efficiency of heat-exchange system；It is clear by pulling up and down
Brush bar, cleaning brush 20 can clear up the sundries above the first flame screen 17.
The foregoing is merely the preferred embodiment of the present invention, are not intended to limit the scope of the invention, every utilization
Equivalent structure or equivalent flow shift made by description of the invention and accompanying drawing content is applied directly or indirectly in other correlations
Technical field, be included within the scope of the present invention.
