Example 1
The tubular membrane sealing structure shown in fig. 1 mainly comprises a tubular membrane element 1, a flower disc 3, a first sealing element 5, a second sealing element 9, a clamping ring 4, a pressing ring 6 and a pressing plate 10. The flower disc 3 is provided with a hole 2, the hole 2 is used for sleeving the tubular membrane element 1, the upper side and the lower side of the flower disc 3 are sealed in an isolated manner through sealing, a clamping ring 4 is sleeved outside one section of the tubular membrane element 1 sleeved with the hole 2, a first sealing element 5 is arranged between the tubular membrane element 1 and the clamping ring 4, and the first sealing element 5 is made of elastic materials (such as rubber); after the tubular membrane element 1 and the snap ring 4 are nested in the opening 2 of the flower disc 3, the snap ring 4 is used for pressing the first sealing element 5 onto the wall of the tubular membrane element 1, and the material of the tubular membrane element 1 can be ceramic or the like.
The tube membrane element 1 can be tightly pressed and fixed in the open pore 2 by the pressing effect of the pressing plate 10, the membrane element can be fixed in the assembly, the pressing ring 6 is arranged between the pressing plate 10 and the faceplate 3, the pressing ring 6 is formed by connecting a first bonding surface 12 and a second bonding surface 13, the first bonding surface 12 is bonded with the pressing plate 10, the second bonding surface 13 is bonded with the tube membrane element 1, a second sealing element 9 is further arranged between the first bonding surface 12 and the faceplate 3, the second sealing element 9 is embedded in a groove 8 on the faceplate 3, the second sealing element 9 is made of polytetrafluoroethylene material, the pressing plate 10 plays a role of mutually pressing the first bonding surface 12, the second sealing element 9 and the faceplate 3, the pressing plate 10 and the faceplate 3 are fixed through bolts, the pressing plate 10 is pressed below the first bonding surface 12, the first bonding surface 12 is bonded with the faceplate 3, and the effect of sealing the lower part of the tube membrane element 1 and the pressing plate 10 in a spaced manner can be achieved.
In addition, the second bonding surface 13 is bonded to the outer wall of the membrane type membrane element 1, the second bonding surface 13 is also tightly pressed against the first sealing element 5, the lower end of the snap ring 4 is fixed to the second bonding surface 13 through the welding point 7, and the lower end of the snap ring 4 is fixed to the second bonding surface 13, so that if the snap ring 4 is not bonded to the faceplate 3, the snap ring 4 still has certain elasticity, the upper end of the snap ring 4 is pressed against the first sealing element 2, the first sealing element 2 is sealed against the tubular membrane element 2, and the snap ring 4 can further seal the tubular membrane element 1 to prevent leakage.
When the tubular membrane sealing structure is installed, the first sealing element 5 is firstly sleeved outside the tubular membrane element 1, the pressing ring 6 is installed below the first sealing element 5, the second binding surface 13 is tightly propped against the first sealing element 5, then the lower end of the clamping ring 4 and the second binding surface 13 are welded and fixed through the welding point 7, the second sealing element 6 is placed on the second binding surface 12, the tubular membrane element 12 and the clamping ring 4 outside the tubular membrane element are integrally pushed into the opening 2 in the flower disc 1, the second binding surface 12 is tightly pressed on the second sealing element 9 through the pressing plate 10, and finally the pressing plate 10 is tightly pressed on the pressing ring 6 on the flower disc 3 through the bolts, so that the second sealing element 9 is tightly pressed, and the sealing of the tubular membrane element 1 is realized.
The sealing structure can be applied to the dehydration separation process of a pervaporation method, and when a membrane component containing the sealing structure is subjected to the dehydration process, a molecular sieve pervaporation tubular membrane can be adopted, wherein one side of the outer wall of the tubular membrane is a feed liquid side, and the inner part of the tubular membrane is a permeation side, so that permeated water can be collected. In use, the first and second sealing members are easily affected by a solvent, and thus the durability thereof is easily lowered. As shown in fig. 2, when the fixing point of the connection point of the faceplate 3 and the pressing plate 10 is located at the side of the second sealing element 9, if the second sealing element 9 is prone to shrink after aging, the pressing plate 10 and the faceplate 3 will be pressed towards the point a in the figure, such a slight movement will cause the joint sealing performance between the faceplate 3 and the snap ring 4 to be reduced, if the faceplate 3 is pressed against the snap ring 4, the first sealing element 3 can be better pressed onto the tubular membrane element 1 by the combined action of the faceplate 3 and the welding point 7, and if the sealing performance of the tubular membrane element 1 is completely concentrated on the welding point 7 after the faceplate 3 is separated from the snap ring 4, the sealing performance of the first sealing element 3 will be significantly reduced.
Therefore, in a modified embodiment, as shown in fig. 2, a structure is adopted in which a slope 11 is provided on the abutting surface of the faceplate 3 and the snap ring 4, and the upper end of the slope 11 is closer to the tubular membrane element 1 than the lower end. With such a structure, when the outer sides of the base flower disc 3 and the pressing plate 10 move towards the point a, the snap ring 4 at the inclined surface 11 moves towards the upper side of the inclined surface 11, and because the upper side 11 is closer to the tubular membrane element 1, after the relative movement occurs, the fit between the snap ring 4 and the flower disc 3 along the inclined surface can still be maintained, so that the double compression of the welding point 7 of the first sealing element 4 and the flower disc 3 is ensured, and the sealing effect of the sealing element in a solvent environment is ensured.
