Dry, dried hot gas is unified to discharge from hot gas discharge port, is incorporated into cyclone separator, cyclone separator can be by one
A little short grained plastic grains for overflowing hot gas discharge port together with hot gas separate from the hot gas of discharge, the heat after separation
Gas can be in hot gas storage tank memory storage, and the hot gas of storage still has higher temperature, in order to accomplish the saving of energy, so hot
The hot gas of gas storage tank memory storage is reintroduced in compressed air efferent duct by air-introduced machine, and the Water-liquid separator of setting can be with
Discharge the steam in hot gas.
When complete dry after, it is necessary to discharge discharges, as long as now extracting valve plate out, allows under plastic grain and falls on cone bucket
It is interior, then discharging is discharged from the discharge valve of cone bucket, discharging operations are very convenient.
Compared with prior art, designing points of the present utility model are by a drying with valve plate to plastics
Particle is dried, and heat exchange drying operation is carried out using hot gas two-way up and down when drying, and completes discharging after dry materials
It is very convenient, substantially increase production efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the scheme of installation of valve plate of the present utility model.
Embodiment
Utility model is described in detail with reference to the accompanying drawings and examples.
As illustrated in fig. 1 and 2, the utility model proposes circulating plastic grain drying device, including drying 1,
It is the hot gas shower nozzle 2 that is arranged on drying upper and lower ends, the compressed air efferent duct 3 for being connected to hot gas shower nozzle 2, empty installed in compression
Air exhauster 4 at the air inlet of gas efferent duct 3 and the air heater 5 on air exhauster 4, the upside side wall of drying 1
The charge door 6 of plastic grain is provided with, and the lower bottom part of the drying 1 is provided with a valve plate slot mouth 7 laterally set, valve plate
One piece of valve plate 8 by the interception isolation of drying stack shell is inserted from side on slot mouth 7, aperture, which is distributed with, on valve plate is less than plastics
The air-vent of grain particle diameter, the circular arc arc length of valve plate slot mouth 7 are more than or equal to the semi arch arc length of the stack shell cross section of drying 1,
The position that the stack shell inwall of drying corresponds to valve plate slot 7 is provided with one and encloses support clamp ring 9 for supporting valve plate 8, and valve plate 8 is in
Circle be inserted into drying is placed in support clamp ring 9 on, and then by drying cylinder inside points every；The top side of drying is set
There is the hot gas discharge port 10 for discharging hot gas, hot gas discharge port 10 is connected with a hot gas storage tank 11, hot gas storage
Tank 11 connects compressed air efferent duct 3 by circulating gas pipe 12.
Junction between compressed air efferent duct 3 and circulating gas pipe 12 is provided with air-introduced machine 13.The inlet end of air exhauster 4
Filter grid bank tube 14 is installed.The bottom of drying 1 is cone bucket, and one of hot gas shower nozzle 2 is fixed on the side of cone bucket, and the cone
