Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.For the person of ordinary skill in the field, from detailed description of the invention, above and other purpose of the present invention, feature and advantage will be apparent.
The preferred embodiment of a kind of Minton dryer that below proposes for the present invention, as shown in Figure 1,
Among 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, charging aperture separation valve door 12 is with horizontal tank body 1 and charging aperture 5 isolation, discharging opening separation valve door 13 is in closed condition with horizontal tank body 1 and discharging opening 6 isolation 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, can certainly be other conduction materials that is fit to, thereby can make inner tank wall keep certain heating-up temperature.This thermal source can adopt guiding to flow increases reflow's cycle, and the thermal efficiency is improved in the enlargement discharge space.
A vacuum degree measuring equipment 11 is set on the horizontal tank body 1, and after dry run began, vacuum degree measuring equipment was constantly measured the vacuum in the tank body, if vacuum does not reach a certain preset value, heater 7 automatic stopped heatings are to prevent the material caking.Condensing unit 8 is connected with vavuum pump 3, and in dry run, steam and solvent that vavuum pump 3 is extracted out transfer in this condenser, can recycle solvent through condensation.
Heat source recovery device 9 is connected respectively with condensing unit 8, heating jacket 2, in condensing unit 8 courses of work, the heat of steam and solvent is flowed to heating interlayer 2 again by heat source recovery device, and the purpose of recycling to play energy can reduce production costs and saves the energy.Cleaning device 10 is connected with horizontal tank body 1, utilizes high-temperature steam that inner tank wall is cleaned after work is finished, and reaches the purpose of dedusting and sterilization.
