Summary of the invention
The purpose of this utility model is to solve in continuous type drying production process, the reasonability of the factors such as water atomization metal dust bake out temperature, time, steam causes the problem of negative effect to product quality, there is provided a kind of reasonable in design, the high-performance solid powder drying device of many warm areas, anti-oxidation, quick steam discharge.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of high-performance solid powder drying device, comprise vertically disposed feed hopper, be positioned at the conveying device of feed hopper lower end, it is characterized in that described conveying device first enters cooling section continuously after bringing-up section, described bringing-up section comprises several warm areas; Before several warm areas, warm area section is provided with the first gas outlet, rear warm area section is provided with air inlet; And in cooling section, be provided with the second gas outlet.Water atomization metal dust water content is higher, must dehumidify in suitable temperature ranges, because metal dust granularity is little, mix moisture wherein and powder surface adhesive rate high, under particularly becoming the stacking states such as block, one-tenth stone roller, obviously satisfied production effect can not be reached only according to a kind of temperature duty and simple exhaust structure, the technical program is in continuous print conveyer belt drying plant, by several warm areas, coordinate the different air pressure in baking furnace, again through cooling section, powder inside and outside moisture is made to be sufficiently vaporized discharge in the short period of time.
As preferably, the first described gas outlet, the second gas outlet are connected to hot-gas recoverer respectively.Recycle hot-air, steam, energy-saving and environmental protection.
As preferably, described conveying device has plane formula conveyor surface, is provided with homogenizing device in feed hopper.Have larger bulk cargo plane, powder is fully spread out, and steam distributes fully.
As preferably, the blast of described air inlet is 1.5 ~ 3Mpa.The blast be applicable to both can not dispel powder, farthest can provide heat again, the globule is gasified and distributes.
As preferably, the temperature height cross arrangement of several described warm areas.Temperature carries out temperature difference alienation arrangement between 200 ~ 500 degree, makes the globule being pasted onto powder surface be evaporated rapidly and can not be inclined to oxidation.
The beneficial effects of the utility model are: can be discharged by furnace air rapidly, accelerate drying rate, raise the efficiency; Bake out temperature can be adjusted to a lower region temperature, prevents from being again oxidized, and reduces energy consumption; By pipeline, steam heat is carried out recycling.
Accompanying drawing explanation
