For reaching above-mentioned purpose, this utility model adopts the following technical scheme that
This utility model is a kind of heat exchange rotary dryer, mainly there are casing, electric cabinet, described casing is provided with circulating fan and runs through the air inlet pipe of casing, casing has baking chamber, baking chamber two side is equipped with some pores, is provided with by motor-driven rotation screen frame (unit) in described baking chamber, makes casing both sides form blow zones, return zone respectively centered by circulating fan, described air inlet pipe forms Ji Fengqu with return zone connected region, is provided with heat-exchange device in described blow zones.
In such scheme, heat-exchange device is followed successively by liquefied gas fire grate, combustor, some heat-exchange tubes, some conducting strips, heat exchange flue from the bottom to top, and wherein, liquefied gas fire grate connects trachea, and heat exchange flue upwardly extends and runs through casing top.
Further, interlock about heat exchange flue and upwards arrange, and connected by some heat-exchange tubes in the middle of the heat exchange flue of left and right sides, make tortuous about gas rising.
Further, some heat-exchange tubes are connected with some conducting strips so that it is have optimal thermal conversion efficiency.
Further, trachea one end connects liquefied gas fire grate, and the other end connects electromagnetic valve, for controlling the keying of liquefied gas fire grate.
Further, baking chamber top is provided with dehumidification tube and upwardly extends and run through casing top, is quickly discharged by dampness.
Further, box outer surface is provided with heat-insulation layer, reduces steam and runs off, reduces energy consumption.
Further, box bottom is provided with some castors, it is simple to mobile.
Further, cabinet front is provided with chamber door, and chamber door can arrange single open-door or double door, preferably double door.
The beneficial effects of the utility model are: this utility model uses liquefied gas as fuel combustion to provide heat energy, heat energy transmission is carried out by conducting strip, material in baking chamber is dried by the heat energy formation hot blast that the wind of blow zones is taken away on conducting strip, its drying course material is completely isolated with the flue gas of burning, after drying materials clean, pollution-free, and the flue-gas temperature passing through tortuous heat exchange flue is substantially reduced, and the flue gas environmentally safe discharged；The rotation screen frame (unit) that baking chamber is used makes material be heated evenly, and the heat-insulation and heat-preservation of casing can reduce heat losses, reduces energy consumption, and it is rationally distributed, drying time is short, efficiency is high, energy-conserving and environment-protective.

Accompanying drawing 1 is internal structure schematic diagram of the present utility model；
Accompanying drawing 2 is the structural representation of heat-exchange device in this utility model；
Accompanying drawing 3 is axonometric chart of the present utility model.
Detailed description of the invention:
In order to make juror can the purpose of this utility model, feature and function be further understood that, hereby lift preferred embodiment and coordinate graphic detailed description as follows:
Refer to shown in Fig. 1-3, system is the structural representation of the preferred embodiment of this utility model, this utility model is a kind of heat exchange rotary dryer, mainly there is casing 1, electric cabinet 2, described casing 1 is provided with circulating fan 3 and runs through the air inlet pipe 11 of casing 1, it is provided with some castors 13 bottom casing 1 and is easy to mobile, casing 1 has baking chamber 4, baking chamber 4 two side is equipped with some pores, described baking chamber 4 top is provided with dehumidification tube 42 and upwardly extends and run through casing 1 top, baking chamber 4 is provided with the rotation screen frame (unit) 51 driven by motor 5, chamber door 14 it is provided with on front side of casing 1, open chamber door 14 can be put in by material screen tray on rotation screen frame (unit) 51；nullCasing 1 both sides are made to form blow zones 6 respectively centered by circulating fan 3、Return zone 7，Described air inlet pipe 11 forms Ji Feng district 8 with return zone 7 connected region，Described blow zones 6 is provided with heat-exchange device，I.e. circulating fan 3 is blown toward blow zones 6，Wind forms hot blast after heat-exchange device and is entered baking chamber 4 by the pore on baking chamber 4 wall，Baking chamber 4 rotates screen frame (unit) 51 rotating，Hot blast material from each layer screen frame (unit) passes over，Material thermally equivalent，And dampness rises and is discharged by dehumidification tube 42，And hot blast enters return zone 7 after baking chamber 4，With the gas of air inlet pipe 11 after Ji Fengqu 8 converges，Again pass by circulating fan 3 and enter blow zones 6，So move in circles，And casing 1 outer surface is provided with heat-insulation layer 12，Reduce heat losses，So required when first time heat exchange energy consumption is maximum，Circulate the most each time and all can carry out heat exchange on the basis of hot blast，Required energy consumption is gradually lowered until stablizing.
nullIn such scheme，Heat-exchange device is followed successively by liquefied gas fire grate 91 from the bottom to top、Combustor 92、Some heat-exchange tubes 93、Some conducting strips 94、Heat exchange flue 95，Wherein，Heat exchange flue 95 upwardly extends and runs through casing 1 top，Heat exchange flue about 95 is staggered upwards to be arranged，And connected by some heat-exchange tubes 93 in the middle of the heat exchange flue 95 of left and right sides，Some heat-exchange tubes 93 are connected with some conducting strips 94，When gas rises along heat exchange flue about 95 is tortuous，Heat energy is transmitted by heat-exchange tube 93 and conducting strip 94，Wind in blow zones 6 takes away the temperature on heat-exchange tube 93 and conducting strip 94 when entering heat-exchange device region，Form hot blast and enter baking chamber 4，And flue gas after heat exchange flue 95 on discharge，Flue gas heat now only has 25-35 DEG C；Liquefied gas fire grate 91 connects trachea 90, and trachea 90 other end connects electromagnetic valve 10, can be controlled the keying of liquefied gas fire grate 91 by electromagnetic valve 10.
