132,8 return air stomatas 132 are divided into four rows and uniformly arrange along the length direction of the slit, and the return air stomata 132 is and institute
It states return air air flue 133 to be connected, certainly, the number and arrangement mode of the return air stomata 132 on each nozzle 13 can bases
Actual needs is freely adjusted.
The method of the 1 dry coating diaphragm of dryer unit (film 2 to be processed) is as follows, high temperature and the gas (work of drying
Make gas) the first gas chamber 11 and the second gas chamber 12 are entered by air inlet 17, then entered in nozzle 13 by airintake wind-tunnel 15,
Then the surface for applying cloth diaphragm is vertically blown out to by nozzle slot 131, due to the support by wind pressure in upper and lower nozzle 13, coating
Diaphragm wavy state motion in dryer unit 1；The damp and hot water vapour generated in drying process can be sprayed by being arranged in
The return air stomata 132 on 13 surface of mouth enters return air air flue 133, and drier then is being discharged via exhaust outlet 18.
In one embodiment, as shown in Figure 3 and Figure 4, two sprays in first gas chamber 11 or second gas chamber 12
Idle guide rolls 16 are additionally provided between mouth 13, the idle guide rolls 16 are fixedly installed on corresponding gas chamber by deflector roll axle bed 19,
In order to realize, preferably transmission effect, the outlet air end of the idle guide rolls 16 and the nozzle 13 are generally aligned in the same plane, Qi Tajie
Structure is similar with scheme corresponding to Fig. 2 with Fig. 1, and this will not be repeated here.
The utility model also provides a kind of drier, and the drier includes the multiple above-mentioned drier lists successively arranged
Member 1 realizes the drying for applying cloth diaphragm by the cooperation of multiple dryer units 1.
It should be noted that this doing without idle guide rolls as illustrated in fig. 1 and 2 can be used in the leading portion of the drier
Dry device unit 1 can contact with idle guide rolls to avoid coating diaphragm, influence the uniformity for applying cloth diaphragm coating layer, and back segment is dry
The dryer unit 1 designed comprising idle guide rolls 16 as shown in Figure 3 and Figure 4 can be used in device unit 1, by leading portion drier list
The drying of member 1, the coating layer applied on cloth diaphragm have finalized the design almost, even if contacting with idle guide rolls 16, also have substantially no effect on painting
The uniformity of coating layer on cloth diaphragm.The idle guide rolls 16 can not only support film diaphragm, increase the movement for applying cloth diaphragm
Speed obtains bigger heat transfer coefficient and bigger rate of drying so as to blow out rate using higher dry gas, and
The idle guide rolls 16 can also keep the winding for applying cloth diaphragm more stable with winding deflector roll cooperation.
