embodiment 1
Tubular membrane component as shown in Figures 1 to 3, the main body of assembly is cylindrical shell 8, at least one end of cylindrical shell 8 is hermetically-sealed construction, mainly comprises floral disc 6 in hermetically-sealed construction, floral disc 6 is provided with perforate, tubular membrane element 1 is socketed with in hole, on floral disc 6, the number of perforate is not restricted, and can be one also can be multiple, floral disc 6 can with cylindrical shell 8 integral type, also can be the end being removably connected to cylindrical shell 8, wherein tubular membrane element 1 can be ceramic membrane or metal film.
The enlarged drawing of hermetically-sealed construction can see Fig. 2, the bottom of the perforate of floral disc 6 is provided with protuberance 9, the top of protuberance 9 is placed with sealing ring 4, the number of sealing ring 4 is not restricted, can be one also can be multiple, the effect of sealing ring to make tubular membrane element 1 be fastened in the perforate of floral disc 6 better, also material liquid side and per-meate side can be sealed better.It is snap ring 3 above floral disc 6, snap ring 3 also central aperture, tubular membrane element 1 is placed in snap ring 3, packing ring 5 is set between snap ring 3 and floral disc 6, the sealing function that it can play, make membrane module after mounting, the material liquid of feed liquid side can not enter to per-meate side, also can play that snap ring 3 is fixed on the surface of floral disc 6 better simultaneously.
The top of snap ring 3 is pressing plates 2, pressing plate 2 is withheld on snap ring 3, snap ring 3 and floral disc 6 are fitted, pressing plate 2 plays and is pressed on floral disc 6 by snap ring 3, and concrete restriction is not done in its concrete structure and fixed position, can exemplify: when floral disc 6 is cylindrical shell 8 integral solder, it also can be fixed on cylindrical shell 8 that pressing plate both can be fixed on floral disc 6, this fixed form both can be fixedly connected with, and also can be removably connect, such as, be bolted, welding etc.Just as shown in fig. 1, floral disc 6 is fixed on the side of cylindrical shell 8, the sectional dimension of floral disc 6 is greater than the cross section of cylindrical shell 8, pressing plate also offers the duct corresponding with tubular membrane element 1, it is made to be socketed on tubular membrane element 1, by bolt 7, pressing plate 2 and floral disc 6 are interconnected and fixed again, make snap ring 3 be squeezed simultaneously, packing ring 5 is compressed.The material of sealing ring 4 and packing ring 5 is polytetrafluoroethylene (PTFE), also can be ethylene propylene diene rubber, fluorubber.
In a kind of embodiment of improvement, the bottom of snap ring 3 also arranges convex rafter 10, convex rafter 10 is socketed in the perforate of floral disc 6, convex rafter 10 can make tubular membrane element 1 fix further, the more important thing is that, when snap ring 3 compresses by pressing plate 2, sealing ring 4 can compress by convex rafter 10 downwards, be out of shape after making it be squeezed, sealed by membrane component better, the concrete size of convex rafter 10 is determined according to the external diameter of tubular membrane element 1, the floral disc 6 hole slot degree of depth, sealing ring 4 wire diameter, and material is stainless steel.And if in duct, only load sealing ring 4, although certain sealing function also can be played, can due to the installation of membrane component and motion, make the sealing effectiveness of sealing ring 4 and unstable.And by convex rafter 10 stretch in duct, sealing ring 4 is compressed time, sealing property can be improved further.
When tubular membrane hermetically-sealed construction is installed, tubular membrane element 1, through the hole slot of floral disc 6, tubular membrane element 1 is placed sealing ring 4, then packing ring 5 is enclosed within entirety on snap ring 3 and is enclosed within tubular membrane element 1, finally compress with pressing plate 2, tight a bolt 7,
When adopting such structure, pressing plate 2 by being applied to the power on snap ring 3, indirect press seal circle 4, belong to forced seal, during practical operation, outside tubular membrane element 1, there is pressure, same purpose, on sealing ring 4, increases the deflection of sealing ring, makes sealing tighter.In addition, packing ring 5 plays cushioning effect in the middle of snap ring 3 and floral disc 6, thus firmly excessively when avoiding tighting a bolt 7 causes sealing to be damaged.
For the shape of protuberance 9, both can be that its upper surface is level as shown in Figure 2 like this; In another embodiment, also can be as shown in Figure 4 like this, its cross section tilts to the center position of floral disc 6, in this case, the shape of sealing ring 4 can be set to single taper, can play the effect of sealing better.
For the perforate of floral disc 6, its structure can be as shown in Figure 2 like this, is the duct of cylindricality; In another embodiment, also can be that offer groove 11 at the top in duct, the size of groove 11 matches with snap ring 3, can be buckled in groove by snap ring 3 better so as shown in Figure 5 like this, improve stability maintenance and sealing effectiveness.
