Further, the rope that destatics is carbon fiber or wire.

Further, it is described destatic rope be arranged in distance described in wear at the position of film path 8-12cm.

Further, support frame or hook are provided in the dry slot, the both ends for destaticing rope are separately connected In support frame as described above or the hook.

Further, described to destatic rope and support frame as described above or the welding hook or pass through screw connection or pass through It snaps connection.

Further, support frame as described above or hook are stainless steel.

Further, wet process diaphragm extraction drying device include it is one or more destatic rope to described, it is each pair of to destatic Two of rope destatic rope and are respectively arranged at the two sides for wearing film path and mutually relatively described wear film way symmetric.

Further, the rope that destatics is set between two neighboring roller.

The utility model by adopting the above technical scheme, has the advantages that compared with prior art

Setting destatics rope in extraction drying, eliminates the electrostatic of extraction dry slot septation, cheap efficient, effect is good It is good.

Detailed description of the invention

It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings Obtain other attached drawings, in which:

Fig. 1 is that a kind of wet process diaphragm of the utility model extracts the structural schematic diagram of drying device；

Fig. 2 is the schematic diagram of the part in Fig. 1.

Wherein, 1, dry slot；2, roller；3, film path is worn；4, rope is destaticed；5, support frame；6, it buckles；7, diaphragm.

Specific embodiment

The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model It can be easier to be understood by the person skilled in the art with feature.The nouns of locality such as "upper", the "lower" addressed in the utility model are roots It is convenient to the usual observation visual angle of tempreature bulb heating system and narration and definition according to those skilled in the art, e.g., "upper" pair Should in Fig. 1 paper upside, "lower" correspond to Fig. 1 in paper downside.

The present embodiment provides a kind of wet process diaphragms to extract drying device, is used to that place to be dried to diaphragm extracted Reason.Shown in referring to Fig.1, wet process diaphragm extracts drying device, multiple for leading including dry slot 1, in the dry slot 1 Draw the roller 2 of diaphragm 7 and one or more in the dry slot 1 destatic rope 4, is formed with diaphragm 7 between the multiple roller 2 Wear film path 3, diaphragm 7 is threaded through in dry slot 1 and moves along the film path 3 of wearing along the film path 3 of wearing, described except quiet The side for wearing film path 3 is arranged in cord 4.

Specifically, it is described destatic rope 4 be carbon fiber or wire, and it is described destatic rope 4 setting distance described in wear At the position of film path 38-12cm.

It is described to destatic rope 4 specifically as shown in Figure 1, being provided with edge in dry wears multiple rollers 2 that film path 3 is successively laid It is set between two neighboring roller 2.Wet process diaphragm extraction drying device includes one or more to the rope 4 and single of destaticing A setting destatics rope 4, as shown in fig. 1, including 4 pairs destatic rope 4 and 1 be separately provided destatic rope 4.Wherein, Two be arranged in pairs destatic that rope 4 is respectively arranged at the two sides for wearing film path 3 and mutually relatively described to wear film path 3 right Claim, i.e., the two is essentially equal with the distance between diaphragm 7, and the tow sides at the same position of face diaphragm 7.The most roller 2 of front side It can be set before or also after the roller 2 of most rear side and destatic rope 4.

Support frame 5 or hook are provided in the dry slot 1, the both ends for destaticing rope 4 are connected to described Support frame 5 or the hook, support frame as described above 5 or hook are stainless steel, preferably 304L and with supervisory stainless steel.Specific to In the present embodiment, as shown in Fig. 2, the both ends for destaticing rope 4 pass through the support frame 5 that buckle 6 is connected to two sides respectively.In addition, It is described destatic rope 4 can also with support frame as described above 5 or the welding hook or pass through screw connection.

The wet process diaphragm extract drying device in, be provided between each roller 2 and on rear side of roller 2 it is multiple destatic rope 4, wherein Part destatics the tow sides that rope 4 is arranged in pairs in diaphragm 7, and electrostatic rope and 7 spacing of diaphragm are controlled in 8-12cm, can be effective It eliminates or reduces electrostatic of the diaphragm 7 in extraction drying process and the diaphragm 7 of the outlet of drying device is extracted according to test result Static value is controlled to 3kv or less.The electrostatic in 4 elimination dry slot 1 of rope is destaticed using carbon fiber (or wire), just Preferably efficiently, it works well.It is easily installed in narrow space, it is good to destatic effect for extraction dry slot 1, is suitable for etchant gas Region.

The above embodiments are only for explaining the technical ideas and features of the present invention, is a kind of preferred embodiment, mesh Be enable those skilled in the art to understand the contents of the present invention and implement them accordingly, can not limit this with this The protection scope of utility model.
