A kind of vertical multi-layer mesh-belt drier, comprise frame, frame is provided with the some drying boxes successively decreased highly step by step, gear-driven guipure is provided with in each drying box, minimum drying box is provided with discharge bucket, the inside of minimum drying box is provided with heater, the highest drying box is provided with feed hopper, be connected by pipeline between two adjacent from low to high drying boxes, set gradually dehydrating unit and blower fan connecting on the pipeline between them.
Further, a kind of preferred version of the present utility model: the number of described drying box is four.
Further, a kind of preferred version of the present utility model: minimum drying box inside is provided with three main heaters, is followed successively by between the bottom of drying box, guipure and the top of drying box.
Further, a kind of preferred version of the present utility model: the inside of other described drying box is provided with assisted heating device, said assisted heating device is arranged between guipure.
Further, a kind of preferred version of the present utility model: described main heater is electric heater unit, hot air heating apparatus, infrared heating device or microwave heating equipment.
Further, a kind of preferred version of the present utility model: described assisted heating device is electric heater unit, hot air heating apparatus, infrared heating device or microwave heating equipment.
Further, a kind of preferred version of the present utility model: be provided with shaking device below described feed hopper.
The beneficial effects of the utility model:
Vertical multi-layer mesh-belt drier heat utilization high rate of the present utility model is high, reaches more than 90%, and dry stock product quality is good.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation sketch of an embodiment of the present utility model;
In figure, 1 is discharge bucket, and 2 is drying box, and 3 is main heater, and 4 is dehydrating unit, and 5 is blower fan, and 6 is guipure, and 7 is assisted heating device, and 8 is feed hopper, and 9 is shaking device.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of vertical multi-layer guipure 6 formula drying machine, comprise frame, frame is provided with the some drying boxes 2 successively decreased highly step by step, gear-driven guipure 6 is provided with in each drying box 2, minimum drying box 2 is provided with discharge bucket 1, the inside of minimum drying box 2 is provided with heater, the highest drying box 2 is provided with feed hopper 8, be connected by pipeline between two adjacent from low to high drying boxes 2, set gradually dehydrating unit 4 and blower fan 5 connecting on the pipeline between them.
The number of the drying box 2 in the present embodiment is four.
Running of the present utility model:
Open machine, the firing equipment reaching minimum drying box 2 warms up machinery, and then blow in machine 5 and dehumidifier, realizes hot blast and passes successively at drying box 2 from low to high.Medicine to be dried is added by feed hopper 8.Medicine enters next stage drying box 2 from the highest drying box 2 successively by the effect of guipure 6, dry.Discharged by discharge bucket 1 after minimum drying box 2 drying.Material adopts the heated-air drying after dehumidifying of next stage successively in running, makes full use of the energy.By heating successively, utilizing for four times, reaching the effect improving energy utilization rate.
Preferably: minimum drying box 2 inside is provided with three main heaters 3, be followed successively by between the bottom of drying box 2, guipure 6 and the top of drying box 2.Upper, middle and lower three heaters are set, can the very high speed of heating and the uniformity of heating, improve dry effect.
Preferably: the inside of other described drying box 2 is provided with assisted heating device 7, said assisted heating device 7 is arranged between guipure 6.Adopt ancillary heating equipment according to different materials, dry speed can be improved.
Preferably: main heater 3 is electric heater unit, hot air heating apparatus, infrared heating device or microwave heating equipment; Assisted heating device 7 is electric heater unit, hot air heating apparatus, infrared heating device or microwave heating equipment.
Preferably: be provided with shaking device 9 below described feed hopper 8, the speed of the charging that can strengthen, dry efficiency is improved.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
