The specific embodiment:

The utility model as shown in Figure 1 is the explosion-proof drying machine of a kind of high-efficiency dustless, main body is a tank body 18, tank body 18 sidewalls have inlet valve 7, the sidewall of tank body 18 bottoms is installed bleeder valve 11, the tank body internal upper part is filter screen trap 6 fixedly, reducing motor 3 is installed at top cover 19 centers of tank body, electric machine main shaft 20 is deep into tank base, as shown in Figure 3, spindle nose is stirring wheel 10 fixedly, top cover 19 both sides are also settled two pipelines respectively, one is anti-blowpipe 21, and another is a negative pressure sucking air pipe 22, and anti-blowpipe 21 is connected with a back-blowing device, negative pressure sucking air pipe 22 connects pouched trapper 15 through air draught valve 4, pouched trapper 15 is connected with centrifugal blower 16 again, and tank base is uncovered structure, and open-mouth connects heat supply bellows 12, heat supply bellows 12 and tank base junction be filter 17 fixedly, and heat supply bellows 12 are connected with a control heating and filtering device.Described back-blowing device is an air accumulator 1, back-flushing valve 2 is installed on the blowback pipeline, and the heating and filtering device is to connect blast pipe at heat supply bellows 12 sidewalls, and the blast pipe other end connects heater 13, heater 13 air inlets are installed air cleaner 8, are installed into air valve 14 on the blast pipe.As shown in Figure 2, described filter screen trap 6 is a disc, vertically welds the vertical siphunculus 23 of many rows in card, and vertical siphunculus 23 1 ends connect hothouse 9, and the other end connects wind sucting chamber 5.

The course of work of the present utility model is as follows:

A, charging: close air intake valve, bleeder valve and back-flushing valve, open inlet valve and air draught valve, and open centrifugal blower, in hothouse, produce negative pressure, with material inspiration hothouse, treat material suck finish after, close the charging valve, carry out dry run.

B, drying: close the charging valve,, make material be in the fluidized drying state by the opening and closing of programme-control air intake valve, air draught valve and back-flushing valve.After the heating of filtered air heater, after the distribution of heat supply bellows, see through filter, material is blown afloat, in air and the material moment contact process, conduct heat and the mass transfer exchange, take away moisture and solvent in the material, air after the mass transfer exchange is under the obstruct of filter screen trap, and tiny material is left in the hothouse, and the air of no dust granules is again through being discharged by blower fan after the pouched trapper dedusting.Behind the long-pending full with substance of the filter screen trap on hothouse top, close the air draught valve, open back-flushing valve, the compressed air that is stored in the air accumulator makes wind sucting chamber's moment malleation, will be bonded at material blowback on the filter screen trap to hothouse.This circulation proceeds to the material finish-drying repeatedly.

C, discharging: the rising of temperature of charge indicates that material is about to dry the end, when reaching dry outlet temperature, gets final product discharging.Close the air intake valve, open and stir and discharging opening, connect appropriate containers at discharging opening, material is pushed out hothouse and enters bearing container under the centrifugal promotion of stirring, and whole process keeps air draught valve and blower fan to open, and under the effect of negative pressure, the material dust can not fly upward.At the interface of discharging opening and bearing container, there is a flexible pipe to be connected to hothouse, the dust from flying when preventing to change bearing container.
