Description
Technical field
The utility model relates to the drying device of PET bottle sheet.
Background technology
In PET bottle sheet dry run, need to carry out crystallization and two technical process of drying tower inner drying in crystallizer at present.Traditional crystallizer respectively becomes a work system with drying tower, separate work, and its shortcoming is: complex structure, cannot continuous drying, production capacity is low.
Utility model content
The utility model technical issues that need to address 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 adopted in the utility model 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, on the dry air inlet of drying tower lower end, be connected with dry gas and blast mechanism, feed bin is arranged on the top of crystallizer, between the discharging opening of feed bin and the charging aperture of crystallizer, be provided with the feed pipe with valve, 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, from crystallization gas air outlet to the crystallization gas pipeline between crystallization gas air inlet, be disposed with cyclone separator, deduster, crystallization blower fan, crystallization heater.
Further, the continuous drier of aforesaid PET bottle sheet, wherein, the structure that described dry gas blasts mechanism comprises: dry gas pipeline, on dry gas pipeline, be disposed with air compressor machine, dehumidifier, drying heater, the air that air compressor machine blasts is successively by entering in drying tower from dry air inlet after dehumidifier, drying heater.
The beneficial effects of the utility model: on the one hand, PET bottle sheet in feed bin is constantly entered into and in crystallizer, is carried out crystallization by feed pipe, PET bottle sheet after crystallization enters in drying tower 1 and is dried, PET bottle sheet after dry 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 air that discharge in drying tower, that discharged 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.
Accompanying drawing explanation
Fig. 1 is the structural representation of the continuous drier of PET bottle sheet described in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and optimum embodiment, the utility model 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, on the dry air inlet of drying tower 1 lower end, be connected with dry gas and blast mechanism, its structure comprises: dry gas pipeline 2, on dry gas pipeline 2, be disposed with air compressor machine 3, dehumidifier 4, drying heater 5, 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, between the charging aperture of the discharging opening of feed bin 7 and crystallizer 6, be provided with the feed pipe 8 with valve, 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 utility model is as follows: the PET bottle sheet in feed bin 7 is constantly entered into and in crystallizer 6, carried out crystallization by feed pipe 8, PET bottle sheet after crystallization enters in drying tower 1 and is dried, PET bottle sheet after dry is discharged from the discharging opening 14 of drying tower 1 bottom, thereby realized the continuous drying of PET bottle sheet, improved the dry production capacity of PET bottle sheet.In dry run, air by air compressor machine 3 constantly blast in dry gas pipeline 2, and by dehumidifier 4, dehumidify successively and drying heater 5 dry heat after form high temperature drying air.High temperature drying air enters in drying tower 1 and upwards and flows, thereby the PET bottle sheet in drying tower 1 is dried, the air that has discharged part heat enters into crystallizer 6 and forms crystallizer 6 for the crystallization gas of 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 and have fine particle, mix and have the gas of fine particle to enter 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, after heating, form high temperature air and be again transported in crystallizer 6, being again formed for the crystallization gas of the crystallization of PET bottle sheet.Crystallization gas adopts air that discharge, that discharged part heat in drying tower 1, 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.
