The specific embodiment
Refer to Fig. 1, show the drying equipment 20 of configuration one vertical type on a forming machine 10 in figure.This drying equipment 20 comprises an initial drying device 22, a vacuum drying cylinder 24 and a material storage tube 26.Above-mentioned three cylindrical shells system from top to bottom sequentially arranges and forms upright form.
One hot air apparatus 28 is this initial drying device 22 of connection.Further, the combination that this hot air apparatus 28 comprises a heater 30 and a guide duct 32.One end system position of this guide duct 32 is in these initial drying device 22 inside, and the other end of this guide duct 32 connects this heater 30.
This heater 30 be the position outside this initial drying device 22, it can be accepted outside air and enters and heated, and for example can utilize air blast that air is inputted in this heater 30 and heated the rising temperature.Hot-air after heating can be by guide duct 32 these initial drying device 22 inside of input.
One end of this initial drying device 22 is initial discharging opening 22a.This initial discharging opening 22a is to should vacuum drying cylinder 24.One first control valve 34 is to connect at this initial discharging opening 22a, and the opening time of this first control valve 34 can drop down onto in order to the plastics material grain of controlling initial drying device 22 quantity of this vacuum drying cylinder 24 by this.
In addition, the first control valve 34 is connected and can reach equally the opportunity that drops out of controlling the certainly initial drying device 22 of plastics material grain on the top of this vacuum drying cylinder 24 and drop out quantity.
One vacuum extractor 36 is to connect this vacuum drying cylinder 24.The combination that this vacuum extractor 36 comprises a vacuum generator 36a and a vacuum solenoid 36b.This vacuum extractor 36 is in order to extract the gas in this vacuum drying cylinder 24.
One end of this vacuum drying cylinder 24 is vacuum discharging opening 24a.This vacuum discharging opening 24a is to should material storage tube 26.One second control valve 38 is to connect at this vacuum discharging opening 24a, and the opening time of this second control valve 38 can drop down onto in order to the plastics material grain of controlling vacuum drying cylinder 24 quantity of this material storage tube 26 by this.
In addition, the second control valve 38 is connected and can reach equally the control plastics material grain on the top of this material storage tube 26 from the opportunity that drops out of vacuum drying cylinder 24 and drop out quantity.
In order more accurately to control the quantity that drops out of plastics material grain, a first sensor 40 is to be arranged on this vacuum siccative cylinder 24.One second sensor 42 is arranged in material storage tube 26.
Use of the present utility model is that a large amount of plastics material grains is placed in this initial drying device 22, and the air outlet 32a of guide duct 32 approaches initial discharging opening 22a, and therefore position can obtain best drying effect at the plastics material grain of this initial discharging opening 22a periphery.
When the first control valve 34, open, position can preferentially fall in vacuum drying cylinder 24 at the plastics material grain of initial discharging opening 22a periphery.The first control valve 34 is closed subsequently, in vacuum drying cylinder 24, a small amount of plastics material grain is only arranged.
Starting vacuum extractor 36 can discharge the gas in vacuum drying cylinder 24.Because the gas pressures in vacuum drying cylinder 24 diminish, make the water boiling point of position in cylinder reduce, can form gas with vacuumizing and discharge therefore be mixed in the aqueous vapor of gas or plastics material grain, and then make plastics material grain reach real drying effect.
The second control valve 38 is opened, and to fall into material storage tube 26 standby for dry plastics material grain.
The drying operation of initial drying device 22 of the present utility model is to continue to carry out, and, after vacuum drying cylinder 24 completes the vacuum drying operation, the plastics material grains in initial drying device 22 can fall into immediately in vacuum drying cylinder 24 and carry out drying operation another time.Be the effect that the utlity model has the small amount drying operation, can shorten the drying time of the plastics material grain that at every turn is supplied to forming machine 10.
Secondly initial drying device 22, vacuum drying cylinder 24 and 26 3 cylindrical shells of material storage tube sequentially from top to bottom are arranged in upright form, and the use amount in its horizontal (horizontal direction) space is less, the field of employment that applicable area is less.
Refer to Fig. 2, another embodiment of the present utility model is that initial drying device 22,24 2 cylindrical shells of vacuum drying cylinder are still and sequentially are arranged in upright form.Yet between vacuum drying cylinder 24 and material storage tube 26, mat one first feed pipe 44 is connected, this material storage tube 26 and mat one second feed pipe 46 adjacent with forming machine 10 is connected.So initial drying device 22 still can reach with the combination of vacuum drying cylinder 24 effect of using less floor area.
The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, therefore any trickle modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
