Utility model content:
The utility model is in order to overcome defect in above-mentioned prior art, provide a kind of cloth bag to be positioned at the drying tower that temperature is very high, the dust entering in cloth bag can not condense in because temperature is low cloth bag surface, the cloth bag that is simultaneously positioned at drying tower can not take additional space, has reduced floor space; And be integrated in respectively secondary drying device, three-stage drying device, the cooler of drying tower bottom, the condensed water producing in primary heater repeatedly utilizes in follow-up secondary drying device, the three-stage drying device course of work, reduce the waste of water resource, the built-in cloth bag multi-stage spray drying machine of energy-conserving and environment-protective.
To achieve these goals, the utility model provides following technical scheme:
Built-in cloth bag multi-stage spray drying machine, comprising: drying tower, cloth bag, spray gun, main drier, blower fan, secondary drying device, three-stage drying device, cooler; Drying tower upper inside surface is distributed with cloth bag, and drying tower porch is provided with spray gun, main drier, and drying tower bottom is independently provided with respectively secondary drying device, three-stage drying device, cooler; Blower fan is connected to form dry wind passage with drying tower entrance, cooler respectively; In main drier, secondary drying device, three-stage drying device, be respectively arranged with heater, between heater, connect by condensing water conduit.
In technique scheme, drying tower top is cylindrical structure, and cylindrical inner surface is distributed with cloth bag.
In technique scheme, built-in cloth bag multi-stage spray drying machine also comprises cyclone separator, and cyclone separator is connected with cloth bag, and cyclone separator outlet is connected with dry wind passage.
In technique scheme, cyclone separator outlet is arranged on the dry wind passage between blower fan and drying tower entrance.
Compared with prior art, the utlity model has following beneficial effect:
1, cloth bag is positioned at the drying tower that temperature is very high, carries out dedusting in dry, and the dust entering in cloth bag can not condense in because temperature is low cloth bag surface, and the cloth bag that is simultaneously positioned at drying tower can not take additional space, has reduced floor space.
2, be integrated in respectively secondary drying device, three-stage drying device, the cooler of drying tower bottom, reduced the floor space of factory building, saved production cost.
3, by condensing water conduit, the heater in main drier, secondary drying device, three-stage drying device is coupled together, can make the condensed water producing in primary heater repeatedly utilize in follow-up secondary drying device, the three-stage drying device course of work, reduce the waste of water resource, energy-conserving and environment-protective.
4, in cyclone separator, fine powder is housed, in granulating working procedure, opens cyclone separator outlet, under blower fan drives, fine powder enters drying tower entrance, because the droplet of spray gun ejection is not yet dry, therefore can produce reuniting effect, fine powder is wrapped in droplet surface, can produce large granular materials.
