Embodiment 1
[0094] like figure 1 , Image 6 , Figure 9 ~ Figure 11 , Figure 13 to Figure 16As shown, the membrane filtration assembly includes a housing 100, a mandrel 200, a membrane core 300, a first end cover assembly 410, a second end cover assembly 420, a membrane core preload structure, a raw material fluid input port 510, and a purified fluid output port 520 , the membrane core 300 is sleeved on the mandrel 200 and is composed of a plurality of membrane filtration units. The membrane core 300 composed of these membrane filtration units is set in an axially compressed state through the membrane core pre-tensioning structure and placed in the Between the first end cap assembly 410 and the second end cap assembly 420, the housing 100 is arranged outside the membrane core 300 and connected to the first end cap assembly 410 and the second end cap assembly 420 respectively; during filtration, After the raw material fluid flows in through the raw material fluid input port 510, the ax...
Embodiment 2
[0121] The structure of the membrane filtration module of embodiment 2 is roughly the same as that of embodiment 1, but the difference is that the output of the purified fluid in this embodiment adopts the publication number CN103657414A applied by the applicant, and the name is "separation and filtration of water entering and exiting at the same end membrane column and its The liquid discharge structure of the hollow mandrel 200 disclosed in the patent document "Method for Treating Feed Liquid". That is: the mandrel 200 is hollow tubular, and the mandrel 200 is provided with a through hole (not shown) that connects the second central hole 321 of each diaphragm 320 with the inner cavity of the mandrel 200. At this time, the The through hole is used as the guide structure 201, the lumen of the mandrel 200 is used as the drainage channel 522, and the shaft end opening of the mandrel 200 is used as the purification fluid output port 520, without the need for the first flange 411 a...
Embodiment 3
[0124] like figure 2 , Figure 7 and Figure 8 As shown, the structure of the membrane filtration assembly of Embodiment 3 is substantially the same as that of Embodiment 1, but the difference is that the diverter plate 610 is located on the second sealing plate 422 of the second end cover assembly 420, and this structure is more conducive to ensuring The diverter plate 610 maintains radial balance relative to the core shaft 200, and further ensures the radial balance of the membrane core 300 installed on the diverter plate 610, which is more conducive to the uniform axial force of the membrane core 300 under the action of the raw material fluid, Avoid slight tilting deformation of the membrane core 300 due to uneven axial force. In addition, the side-inlet fluid distribution channel can utilize the force of the raw material fluid on the wall of the disk body above the fluid inlet hole 611 to push the disk body to drive the mandrel 200 to move in the axial direction, and fu...
