The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of polymer solids dry materials tackify high vacuum rotary drum cooling device of accelerating the cooling rate of rotary drum is provided.
For achieving the above object, the technical solution of the utility model is: a kind of polymer solids dry materials tackify high vacuum rotary drum cooling device, it comprises rotary drum and cooling structure, this cooling structure comprises vacuum-pumping tube, separator, heat exchanger and blower fan, the a end of vacuum-pumping tube is connected with rotary drum, the b end of vacuum-pumping tube is communicated with the inlet end of blower fan by separator and heat exchanger, and the outlet side of blower fan is communicated with the c of vacuum-pumping tube end, and the d end of vacuum-pumping tube is communicated with source nitrogen by advancing nitrogen valve.
When the rotary drum tackify is finished the need cooling, in rotary drum, charge into a certain amount of nitrogen, then start blower fan.Carry out the later nitrogen of heat exchange with material and extracted out by blower fan, elder generation, so moves in circles after the heat exchanger heat exchange is sent cooled nitrogen into rotary drum again by the blower fan outlet at last through separation, thereby can realize the cooling of rotary drum apace.
This vacuum-pumping tube is made of the upper and lower semicircle pipe that the centre is provided with dividing plate near rotary drum one side, and the b end is located on first pipe, and c end and d end are located on the lower semicircle pipe, and a end stretches into end in the rotary drum for upper and lower semicircle pipe.This programme is transformed existing vacuum-pumping tube, and bleed-off passage and outlet passageway are separated.
Taken away for fear of the cold nitrogen that just has been input into, the end that this upper and lower semicircle pipe stretches in the rotary drum is made the fork structure with an angle, and angle is 90～180 °, thereby improves cooling effectiveness.
The end that this upper and lower semicircle pipe stretches in the rotary drum also is connected with filter mantle respectively, the effect of filter mantle avoids the material of rotary drum the inside in vacuumizing the tackify process to be taken away in a large number by vacuum system and be provided with, and general rotary drum can be provided with several filter mantles.
On the end face of first pipe, be provided with a baffle plate, and this baffle plate only can avoid blower fan the nitrogen that does not enter rotary drum as yet in the lower semicircle pipe to be given the risk of taking away to opening away from rotary drum one side away from rotary drum.
This vacuum-pumping tube is connected with pumped vacuum systems by the vacuum line valve away from the e end of rotary drum.The technical program is directly to improve on existing vacuum-pumping tube, after exhausting vacuum, when needing cooler drum, only needs the vacuum line valve cuts out, and blower fan is opened to get final product again.
Also be provided with inlet valve between this vacuum-pumping tube b end and the separator, also be provided with outlet valve between this vacuum-pumping tube c end and the blower fan, realize the switch control of cooling circuit.
Described separator is a cyclone separator, and blower fan is an air blast.
Compared with prior art, vacuum-pumping tube and the cooling circuit thereof of the utility model by being communicated with rotary drum when the rotary drum tackify is finished the need cooling, charges into a certain amount of nitrogen in rotary drum, then start blower fan.Carrying out the later nitrogen of heat exchange with material is extracted out by blower fan, earlier through separation and after the heat exchanger heat exchange, by the blower fan outlet cooled nitrogen is sent into rotary drum more at last, so move in circles, can under not influencing the situation that rotary drum rotates, allow the temperature in the rotary drum drop to required temperature range faster.
