Description
Technical field
The utility model relates to a kind of drying device, relates in particular to a kind of hydroxypropyl cellulose drying device.
Background technology
Hydroxypropyl cellulose has hot gel characteristic, there is excellent cold water solubles and hot water-insoluble characteristic, it is a kind of nonionic mixed cellulose ethers, there are the performances such as good dispersion, emulsification, thickening, bonding, water conservation and guarantor's glue, are widely used in the industry such as building, coating, synthetic resin, pottery, tobacco, weaving, daily use chemicals, petrochemical industry and electronics.The quality of hydroxypropyl cellulose quality directly has influence on its serviceability, and in producing hydroxypropyl cellulose process, dry run is vital, if dry not in place, moisture is more, and hydroxypropyl cellulose may be reunited; If the moisture of hydroxypropyl cellulose is very few, can produce a large amount of dust, waste material.
Existing hydroxypropyl cellulose drying device is general adopts first to dry, through one baking operation, for the moisture content of material is declined, must improve bake out temperature or extend drying time, and this can have a certain impact to the performance of material, cause dry materials weak effect; On the other hand, because dried hydroxypropyl cellulose contains more dust, if be directly discharged in workshop, not only waste a large amount of raw materials, and operative employee's body and mind is caused to certain harmful effect.
Utility model content
The problem that the utility model is poor for prior art drying unit drying effect, dust pollution is large, object is to provide a kind of hydroxypropyl cellulose drying device of efficient, no dust pollution.
For achieving the above object, the technical solution adopted in the utility model is as follows: a kind of hydroxypropyl cellulose drying device, comprise the first air blast, the first described air blast is connected with primary heater by pipeline, described primary heater is connected with the first cyclone separator by pipeline, the first described cyclone separator is connected with the first drying unit by pipeline, the first described drying unit is connected with the second cyclone separator by pipeline, the second described cyclone separator top is connected with the first air-introduced machine by pipeline, the first air-introduced machine is connected with the first sack cleaner by pipeline, the second described cyclone separator bottom is connected with the first Blowing stopper by pipeline, the first Blowing stopper is connected with the 3rd cyclone separator by pipeline, the 3rd described cyclone separator is connected with the second drying unit by pipeline, the second described drying unit is connected with the 4th cyclone separator by pipeline, the 4th described cyclone separator top is connected with the second air-introduced machine by pipeline, the second described air-introduced machine is connected with the second sack cleaner by pipeline, the 4th described cyclone separator lower end is connected with the second Blowing stopper by pipeline, the second described Blowing stopper is connected with tramp iron separator by pipeline, described tramp iron separator lower end is provided with vibratory sieve.
The 3rd described cyclone separator is connected with secondary heater by pipeline, and described secondary heater is connected with the second air blast by pipeline.
Compared with prior art, the beneficial effects of the utility model are mainly reflected in: drying device adopts the second heating, drying device, and drying effect is good; In drying device, be provided with bag-type dust collector, can greatly reduce dry run dust pollution.
