Abstract
The invention discloses a continuous drying unit for PET bottle chips, capable of continuously drying and low in power consumption. The continuous drying unit comprises a drying column, a crystallizer and a bin. The bottom of the drying column is provided with a discharge hole. A drying gas blow mechanism is connected to a drying gas inlet at the lower end of the drying column. The bin is disposed above the crystallizer. A feed pipe with a valve is disposed between a discharge hole of the bin and a feed hole of the crystallizer. The crystallizer is disposed at the top of the drying column and communicated with the drying column. The lower end of the crystallizer is provided with a crystallization gas inlet. The top of the crystallizer is provided with a crystallization gas outlet. A cyclone separator, a dust collector, a crystallization fan and a crystallization heater are sequentially disposed on a crystallization gas pipe between the crystallization gas outlet and the crystallization gas inlet.
Description
Technical field
The present invention relates to the drying device of PET bottle sheet.
Background technology
Need to carry out crystallization and two technical process of drying tower inner drying in crystallizer in PET bottle sheet dry run at present.Traditional crystallizer respectively becomes a work system with drying tower, separate work, and its shortcoming is: complex structure, can't continuous drying, production capacity is low.
Summary of the invention
The technical issues that need to address of the present invention are: provide a kind of energy continuous drying, the continuous drier of the PET bottle sheet that production capacity improves greatly, energy consumption is low.
For addressing the above problem, the technical solution used in the present invention is: the continuous drier of PET bottle sheet, comprise: drying tower, crystallizer and feed bin, the bottom of drying tower is provided with discharging opening, be connected with dry gas on the dry air inlet of drying tower lower end and blast mechanism, feed bin is arranged on the top of crystallizer, be provided with the feed pipe with valve between the discharging opening of feed bin and the charging aperture of crystallizer, described crystallizer is arranged on the top of drying tower, and crystallizer is connected with drying tower, the lower end of crystallizer is provided with crystallization gas air inlet, the top of crystallizer is provided with crystallization gas air outlet, be disposed with cyclone separator from crystallization gas air outlet to the crystallization gas pipeline between crystallization gas air inlet, deduster, the crystallization blower fan, the crystallization heater.
Further, the continuous drier of aforesaid PET bottle sheet, wherein, the structure that described dry gas blasts mechanism comprises: the dry gas pipeline, be disposed with air compressor machine, dehumidifier, drying heater on the dry gas pipeline, the air that air compressor machine blasts is successively by entering in drying tower from dry air inlet after dehumidifier, drying heater.
Beneficial effect of the present invention: on the one hand, PET bottle sheet in feed bin constantly enters in crystallizer and carries out crystallization by feed pipe, PET bottle sheet after crystallization enters in drying tower 1 and carries out drying, PET bottle sheet after drying is discharged from the discharging opening of drying tower bottom, thereby has realized the continuous drying of PET bottle sheet; On the other hand, crystallization gas adopts discharge in drying tower, air that discharged the part heat, and constantly circulation, thereby greatly reduces the energy consumption in PET bottle sheet dry run, has therefore reduced the drying cost of PET bottle sheet.
The accompanying drawing explanation
Fig. 1 is the structural representation of the continuous drier of PET bottle sheet of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and optimum embodiment, the present invention is described in further details.
As shown in Figure 1, the continuous drier of PET bottle sheet, comprise: drying tower 1, crystallizer 6 and feed bin 7, the bottom of drying tower 1 is provided with discharging opening 14, be connected with dry gas on the dry air inlet of drying tower 1 lower end and blast mechanism, its structure comprises: dry gas pipeline 2, be disposed with air compressor machine 3, dehumidifier 4, drying heater 5 on dry gas pipeline 2, and the air that air compressor machine 3 blasts is successively by entering in drying tower 1 from dry air inlet after dehumidifier 4, drying heater 5.Feed bin 7 is arranged on the top of crystallizer 6, be provided with the feed pipe 8 with valve between the charging aperture of the discharging opening of feed bin 7 and crystallizer 6, top and crystallizer 6 that described crystallizer 6 is arranged on drying tower 1 are connected with drying tower 1, the lower end of crystallizer 6 is provided with crystallization gas air inlet 61, the top of crystallizer 6 is provided with crystallization gas air outlet 62, from crystallization gas air outlet 62 to the crystallization gas pipeline 9 between crystallization gas air inlet 61, is disposed with cyclone separator 10, deduster 11, crystallization blower fan 12, crystallization heater 13.
Operation principle of the present invention is as follows: the PET bottle sheet in feed bin 7 constantly enters in crystallizer 6 and carries out crystallization by feed pipe 8, PET bottle sheet after crystallization enters in drying tower 1 and carries out drying, PET bottle sheet after drying is discharged from the discharging opening 14 of drying tower 1 bottom, thereby realized the continuous drying of PET bottle sheet, improved the production capacity of PET bottle sheet drying.In dry run, air is constantly blasted in dry gas pipeline 2, is also passed through successively to form the high temperature drying air after dehumidifier 4 dehumidifying and drying heater 5 dry heat by air compressor machine 3.The high temperature drying air enters in drying tower 1 and upwards and flows, thereby the PET bottle sheet in drying tower 1 is carried out to drying, the air that has discharged the part heat enters into crystallizer 6 and forms the crystallization gas of crystallizers 6 for the crystallization of PET bottle sheet, crystallization gas release heat again in crystallizer 6.Experienced in gas after dry and crystallization, that discharged heat and mixed fine particle arranged, mixing the gas that fine particle is arranged enters to crystallization gas pipeline 9 from crystallization gas air outlet 62, and enter into successively separation, the further dedusting of deduster 11 that cyclone separator 10 carries out fine particle, pure air after dedusting is transported to heating in crystallization heater 13 under the effect of crystallization blower fan 12, form high temperature air after heating and again be transported in crystallizer 6, again being formed for the crystallization gas of the crystallization of PET bottle sheet.Crystallization gas adopts that discharge in drying tower 1, air that discharged the part heat, and constantly circulation, thereby greatly reduces the energy consumption in PET bottle sheet dry run, has therefore reduced the drying cost of PET bottle sheet.
