Membrane module is the most important equipment of membrane separation technique, and its structure is broadly divided into 1. slab constructions such as plate and frame, spiral wound.2. tubular structure such as shell-and-tube, capillary tube and hollow fiber film assembly etc..Shell-and-tube membrane module structure is simple, installs, detachable maintaining is convenient, can bear the advantage such as operating mode of high pressure, high temperature, industrial is widely used.Owing to membrane separation technique need to keep pressure differential or the concentration difference of film both sides, pressure and temperature is higher sometimes, if separation process to obtain dense organic solvent, is not allow for absolutely leakage, therefore that seal request is higher.
Traditional film tube seal structure uses O RunddichtringO to seal, O RunddichtringO is forced sealing, and sealing ring needs to bear bigger preload pressure and deformation, easily reveals when equipment pressure is bigger, when high temperature or long-time use, the deformation of sealing ring cannot recover, it is impossible to secondary uses.The excessive O RunddichtringO of pretightning force is likely compressed into plastic deformation and loses sealability, and pretightning force is too small does not have again sealing function, therefore that installation requirement is higher.
Summary of the invention
The purpose of this utility model is to provide a kind of process simple, easy for installation, good seal performance and can bear the film tube seal structure of bigger pressure and high temperature, and concrete technical scheme is:
A kind of film tube seal structure, include membrane tube, floral disc, sealing ring and pressing plate, at least one end of cylinder is provided with floral disc, floral disc offers opening, being socketed with membrane tube in opening, the surrounding in the outside of the opening part of floral disc offers groove, is provided with sealing ring in the trench, being additionally provided with pressing plate in the outside of floral disc, sealing ring is compressed by pressing plate.
It is bolted fixing between pressing plate and floral disc.
The material of described membrane tube is selected from metal, pottery or glass.
The width in the cross section of sealing ring is more than the width of the inwall of membrane tube outer to groove.
Being additionally provided with convex rafter towards the side of floral disc on pressing plate, convex rafter is embedded in the groove of the opening part of floral disc, and is held out against by sealing ring.
Convex rafter can also be detachable.
Sealing ring is made up of internal elastomeric layer and outside sealing material layer；The material of elastomeric layer is rubber；The material of sealing material layer is selected from politef or rubber.
Beneficial effect
Film tube seal structure of the present utility model, simple in construction, easy for installation without pretightning force, good sealing effect, the operating mode of High Temperature High Pressure can be born, combined seal ring can be reused and reduce cost.

Detailed description of the invention
Being described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of same or like function from start to finish.The embodiment described below with reference to accompanying drawing is illustrative of, it is intended to be used for explaining this utility model, and it is not intended that to restriction of the present utility model.In description of the present utility model, it will be appreciated that, term " " center ", " longitudinal direction ", " transverse direction ", " length ", " width ", " thickness ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end " " interior ", " outward ", " clockwise ", orientation or the position relationship of the instruction such as " counterclockwise " are based on orientation shown in the drawings or position relationship, it is for only for ease of description this utility model and simplifies description, rather than the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.In description of the present utility model, " multiple " are meant that two or more, unless otherwise expressly limited specifically.It should be understood that it can be joined directly together with other elements or be indirectly connected to other elements, and is inserted with element between them when an element was mentioned with another element " connection ".Unless there are clearly contrary explanation, otherwise term " including " and " having " are interpreted as stating and comprise listed element, and non-excluded arbitrarily other elements.
The outside of the opening part of the floral disc 2 described in this utility model, refers to the top in Fig. 2, namely refers to the lateral direction at the two ends of cylinder 1.The outside of floral disc 2 refers to that floral disc 2 is towards the side outside cylinder.
Embodiment 1
This utility model is described further by embodiment below in conjunction with accompanying drawing.
Film tube seal structure as depicted in figs. 1 and 2, include membrane tube 6, floral disc 2, sealing ring 4 and pressing plate 3, at least one end of cylinder 1 is provided with floral disc 2, offering opening in floral disc 2, be socketed with membrane tube 6 in opening, the outside of the opening part of floral disc offers groove 7, groove 7 is provided with sealing ring 4, be additionally provided with pressing plate 3 in the outside of floral disc 2, sealing ring 4 is compressed by pressing plate 3, can pass through bolt 5 and be connected fixing between pressing plate 3 with floral disc 2.This film tube seal structure is generally used for sealing inoranic membrane membrane tube, it is possible to being earthenware, glass tubing, it is also possible to be metal tube, its configuration can be single tube or multitube.
The external diameter of sealing ring 4 is slightly larger than the width of membrane tube 6 outer to floral disc 2 open groove inwall.The elastomeric material installing rear sealing ring 4 deforms upon, and makes sealing ring 4 fit closely with groove 7 in membrane tube and floral disc thus producing sealing force to form sealing.When becoming big along with pressure increases sealing ring external and internal pressure difference, pressure makes the groove 7 of the encapsulant outside combined seal ring and membrane tube and floral disc fit more closely, thus reaching the effect of self-tightening sealing, loading onto pressing plate to prevent combined seal ring to be extruded when pressure is bigger and sealing.This self-energized seal maximum pressure can reach 30MPa, and the sealed material that temperature is more different may range from-150 DEG C to 250 DEG C.
In order to improve sealing effectiveness, in one embodiment, as in figure 2 it is shown, be additionally provided with convex rafter towards the side of floral disc on pressing plate 3, convex rafter is embedded in the groove 7 of the opening part of floral disc, and is held out against by sealing ring 4.Sealing ring can be clamped in groove by the effect of convex rafter better.It addition, convex rafter can also be detachable, when adopting the sealing ring of different size, it is possible to pulled down to adapt to the shape of sealing ring.Sealing ring 4 is made up of internal elastomeric layer and outside sealing material layer；The material of elastomeric layer is rubber；The material of sealing material layer is selected from politef or rubber.
In the technical solution of the utility model, owing to tube side and shell side all subject pressure, it is contemplated that various inefficacies, the general material of cylinder, floral disc, pressing plate and bolt is metal, it is possible to is designed with reference to GB150.1 ~ 4-2011 and GB/T151-2014, checks, manufactures.Can also be nonmetallic, it is possible to reference to its corresponding standard.
