Background technique
Membrane module is one of device commonly used carried out liquid or gas separation.Wherein membrane module is a kind of film to be assembled in an elementary cell equipment with certain form, then the device that in realizing mixture under the effect of extraneous driving force, each component is separated, industrial membrane module form commonly used generally is divided into five kinds: plate and frame, spiral wound, circular pipe type, doughnut formula and capillary type, first two is used flat sheet membrane, and rear three uses tubular membrane.And using tubular membrane generally to adopt sleeve type structure to be assembled.For current constant temperature diaphragm component, be mainly to keep the component sealing tube sheet indeformable, the seal groove of sealed pipe plate and sleeve pipe coaxality, need to be connected and sealed between shell in membrane module and tube sheet.Yet, in the prior art of studying both at home and abroad at present, the shell of membrane module and tube sheet all adopt the mode of welding to be connected and sealed, this will make in welding process, can because when welding higher temperature cause inevitably error of tube sheet temperature distortion or manual operation institute, finally cause membrane module film tube and tube plate seal groove and the sleeve pipe coaxality is excessive and the defect of seal failure.
The model utility content
The welding manner that the utility model adopts for the shell that overcomes membrane module in prior art and tube sheet in the time of can making to weld higher temperature cause inevitably error of tube sheet temperature distortion or manual operation institute, finally cause membrane module film tube and tube plate seal groove and the sleeve pipe coaxality is excessive and the defect of seal failure.The Hermetical connecting structure of a kind of membrane module shell and tube sheet is provided, and the technical program is achieved in that
The Hermetical connecting structure of a kind of membrane module shell and tube sheet comprises:
The tube-like envelope of a plurality of single tube films is housed, and described tube-like envelope comprises two end sockets that are connected with the opposite end of described tube-like envelope respectively;
In order to seal two tube sheets of described tube-like envelope, each described tube sheet is separately fixed on each described end socket;
In order to seal respectively two margin plates of each described opposite end of described tube-like envelope, each described margin plate is fixed on each described tube sheet at the place, opposite end of described tube-like envelope respectively.
Technique scheme of the present utility model, in order to make to contact tube sheet face better tightness, the surface of contact of described tube sheet is fixed with for sealing the seal ring of described tube-like envelope.
Technique scheme of the present utility model, the fixed end of each described end socket and each described tube sheet is fixed with the flange I.
Technique scheme of the present utility model, each described margin plate is the flange II.
Technique scheme of the present utility model, described flange I is fixedly connected with by the bolt mode with described flange II.This practicality
This novel described membrane module, preferably, be applicable to constant temperature diaphragm component.
The utility model in use, at first correspondingly is fixed in flange I and flange II on end socket and each opposite end of tube-like envelope by welding or engage thread; Then seal ring is placed between flange, utilizes the bolt will be to the flange fixing seal connected.But the utility model also is not limited to this, for example, also can in the processing casting process, directly cast out with the end socket of flange and the flange on each opposite end of tube-like envelope.
Therefore, the utlity model has following beneficial effect:
The utility model adopts flange connection to replace welding connecting mode commonly used in prior art between shell and tube sheet, and the tube sheet temperature distortion that while effectively having solved welding, higher temperature causes or manual operation institute be error inevitably;
The utility model has overcome the seal groove of film tube and tube plate of membrane module and the sleeve pipe coaxality is excessive and the defect of seal failure;
The utility model processing method is simple, and simple and convenient assembly is convenient to dismounting;
The utility model can make the enclosure interior sealing effectively.

Embodiment
Following non-limiting example can make the present invention of those of ordinary skill in the art's comprehend, but does not limit the present invention in any way.
Embodiment 1
The involved membrane module of the utility model is constant temperature diaphragm component typically, and except the Hermetical connecting structure of membrane module shell of the present invention and tube sheet, miscellaneous part is the parts of membrane module commonly used in the art.
Referring to accompanying drawing 1, the Hermetical connecting structure of membrane module shell of the present utility model and tube sheet comprises 1, one the first end socket 11a of a tube-like envelope and second an end socket 11b, tube sheet 2a, 2b and such as the seal ring of O type ring 3a, 3b, 3c, 3d.
Tube-like envelope 1 has respectively and the opposite end 1a of tube-like envelope 1, margin plate 12a, the 12b that 1b is connected.Typically, margin plate 12a, 12b for good and all are fixed on the edge of tube-like envelope 1 two ends 1a, 1b, as margin plate 12a, 12b are flange II a122, flange II b122, flange II a122 and flange II b122 can be fixed on the edge of tube-like envelope 1 two ends 1a, 1b by welding or engage thread.
