Abstract
The invention relates to a method for increasing the temperature of cold powder fast. The cold powder with the temperature ranging from -20 DEG C to -3 DEG C is placed into an inner cavity of a harrow-type drying machine. The inner cavity of the harrow-type drying machine is provided with a rotating shaft with a spiral belt, a spiral belt disc is arranged around the rotating shaft, and a spiral belt inner cavity is hollow and is communicated with a hollow inner cavity of the rotating shaft. Circulating water with the temperature ranging from 20 DEG C to 40 DEG C flows into the spiral belt inner cavity through a water inlet in one end of the rotating shaft and flows out through a water outlet in the other end of the rotating shaft, and the flow speed of the circulating water is not less than 30 steres per hour. The inner cavity of the drying machine is inflated with dried nitrogen so that the pressure of the inner cavity of the harrow-type drying machine can be increased to the range from 0.4 Mpa to 0.5 Mpa, the rotating shaft is started to stir the cold powder, the rotating speed of the rotating shaft during stirring ranges from 30 rpm to 40 rpm, and the stirring time ranges from 30 minutes to 40 minutes. The drying technology is applied through the improved harrow-type drying machine, the new drying technical procedure is adopted, the problem of sudden empty production of the powder can be avoided, and the fermentation speed can be improved greatly.
Description
Technical field
The present invention relates to the technical field of chemical industry hot-melt adhesive powder " material of waking up " technique, a kind of specifically method that freezing powder is rapidly heated.
Background technology
Copolymer nylon, copolyester hot melt adhesive be the production process for the lining cloth of weaving with pulverulence, and therefore the powder that different grain size distributes will be made by graininess or block PUR by hot-melt adhesive powder factory.Because the brittle temperature of copolymer nylon, copolyesters is very low, be generally-30 DEG C--50 DEG C and need under liquid nitrogen exists, carry out deep cooling crush and just can obtain the powder of size distribution needing.
After deep cooling crush, from pulverizer powder out ,-30 DEG C of--20 DEG C of left and right, needing to heat up makes it reach environment temperature, and PUR industry is called " material of waking up ".But, gasify rapidly and make powder " expanded " owing to being contained in nitrogen in freezing powder if be directly exposed to intensification meeting in air.The powder particle surface of " expanded " is coarse, bulk density declines affect its mobile performance production brings very large trouble to lining cloth.Meanwhile, freezing powder is exposed in air and can absorbs in a large number moisture and cause unnecessary problem, only has for this reason freezing powder is placed on and in the sack of lining form, is placed in air and slowly heats up, and conventionally needs 36-48 hour.So just make powder occupy a large amount of production spaces and also extended the production cycle.
Summary of the invention
The object of the present invention is to provide a kind of method that freezing powder is rapidly heated, it utilizes improved rake type drier, has effectively shortened the drying time of freezing powder, has reduced production space, has shortened the production cycle.
To achieve these goals, technical scheme of the present invention is: a kind of method that freezing powder is rapidly heated, it is characterized in that: described in the method that is rapidly heated be, adopt the rake type drier of transformation as heating device, the freezing powder of-3 DEG C～-20 DEG C is put into rake type drier inner chamber, this rake type drier inner chamber is provided with a turning cylinder with ribbon, the setting of ribbon coiling turning cylinder, this ribbon inner chamber hollow and with the mutual UNICOM of hollow cavity of turning cylinder, the recirculated water of 20 DEG C-40 DEG C flows into from the water inlet of turning cylinder one end, after ribbon inner chamber, delivery port by the turning cylinder other end flows out, the flow of recirculated water is not less than 30m
3/ h, rake type drier inner chamber is filled with dry nitrogen, make the pressure of rake type drier inner chamber be increased to 0.4Mpa-0.5 Mpa, starting turning cylinder stirs freezing powder, turning cylinder rotating speed when stirring is 30rpm-40rpm, and mixing time is 30 minutes-40 minutes, then passes into the recirculated cooling water of 20 DEG C-40 DEG C in the chuck of rake type drier, powder in rake type drier is dried, and the flow of recirculated cooling water is not less than 30m
3/ h, deserves your powder of rake type drier while reaching 20 DEG C, stops being dried, and powder is taken out.
The invention discloses a kind of method that freezing powder is rapidly heated, it adopts follow-on rake type drier, and coordinate new drying technology process, the problem that can avoid powder " cruelly empty " to produce can improve again the speed of " material of waking up " greatly, can shorten compared to existing technologies the awake material time about 1 hour.
