Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.For person of ordinary skill in the field, from detailed description of the invention, above and other object of the present invention, feature and advantage will be apparent.
Be below the preferred embodiment of a kind of Minton dryer of the present invention's proposition, as shown in Figure 1,
In Fig. 1, horizontal tank body 1 is provided with heating jacket 2, horizontal tank body 1 is connected respectively with vavuum pump 3, vibrating device 4, charging aperture 5, discharging opening 6, horizontal tank body 1 is isolated with charging aperture 5 by charging aperture separation valve door 12, horizontal tank body 1 is isolated with discharging opening 6 by discharging opening separation valve door 13, is in closed condition before these two separation valve door work.Heater 7 is connected with heating jacket 2, and thermal source wherein can be hot water, conduction oil or low-pressure steam, the conduction material that can certainly be applicable to for other, thus can make the heating-up temperature that inner tank wall keeps certain.This thermal source can adopt guiding flowing to increase reflow's cycle, enlargement discharge space, improves the thermal efficiency.
Horizontal tank body 1 is arranged a vacuum degree measuring equipment 11, after dry run starts, vacuum degree measuring equipment constantly measures the vacuum in tank body, if vacuum does not reach a certain preset value, heater 7 stops heating automatically, lumps to prevent material.Condensing unit 8 is connected with vavuum pump 3, and in dry run, the steam that vavuum pump 3 is extracted out and solvent transfer in this condenser, can recycle through condensation to solvent.
Heat source recovery device 9 is connected respectively with condensing unit 8, heating jacket 2, in condensing unit 8 course of work, the heat of steam and solvent is flowed to heating interlayer 2 again by heat source recovery device, to play the object that energy regenerating utilizes, can production cost be reduced and save the energy.Cleaning device 10 is connected with horizontal tank body 1, utilizes high-temperature steam to clean inner tank wall after work completes, and reaches the object of dedusting and sterilization.
During work, material to be dried is filled in charging aperture 5, opens the charging aperture separation valve door 12 between charging aperture 5 and horizontal tank body 1, by material transferring in tank body, and close this separation valve door 12.Vavuum pump 3 is started working, and horizontal tank body 1 is evacuated to vacuum state.
Vibrating device 4 and heater 7 start simultaneously, vibrating device 4 is arranged on the base of horizontal tank body 1, its mechanical exciting force produced drives horizontal tank body 1 to produce and is synchronized with the movement, make material in tank body under vacuum conditions, through secondary ballistic fluidisation, in suspended state, simultaneously because tank body produces exciting force by mechanical exciting, making in tank body each position by 900---1800UPM vibrates, and produces the amplitude of 15-35mm.Material in tank body becomes fluidized state under the effect of vibrating device, and fully contact with the inwall of horizontal tank body 1, realize heat transmission and constantly update the area of heating surface, storeroom lamellar spacing is increased, heat exchange is carried out by the hot media in heating jacket 2, the temperature of material is constantly raised, and the hydrone in material or solvent gasify rapidly disengaging, and the hydrone gasified and solvent rise rapidly and to be taken away by vavuum pump 3.
In the process, the vacuum of vacuum degree measuring equipment 11 to horizontal tank body 1 inside is monitored, when this low vacuum is in a certain preset value, heater 7 stops heating horizontal tank body 1, vavuum pump 3 continues to carry out vacuum pumping to horizontal tank body 1, until this tank body vacuum meets or exceeds described preset value, heater 7 starts to continue heating to horizontal tank body and reaches drying purpose.
After a scheduled time, vavuum pump 3 stops vacuum pumping, heater 7 stops heating, open the discharging opening separation valve door 13 between horizontal tank body 1 and discharging opening 6, dried material is taken out to discharging opening 6, close this separation valve door 13, then close vibrating device 4, whole dry run completes.
The foregoing is only preferred embodiment of the present invention, be not used for limiting practical range of the present invention; If do not depart from the spirit and scope of the present invention, the present invention is modified or equivalent to replace, in the middle of the protection domain that all should be encompassed in claim of the present invention.
