Specific implementation mode

With reference to attached drawing the utility model can recoil tablet membrane filter unit and device specific implementation mode detailed description such as Under, the utility model can recoil tablet membrane filter unit and device characteristic and advantage will be apparent, and wherein attached drawing discloses It is the special case of the utility model rather than the full content of the utility model.

Referring to Fig. 1,2 and 3, the tablet membrane filter unit (100) that can recoil, which includes multiple rectangles, can recoil tablet membrane filtration Diaphragm (110) and the box that draws water (120) for being located at plate membrane filtration membrane (110) both ends that can recoil；The tablet that recoils It is supporter (112) that membrane filtration diaphragm (110) two sides, which is in the middle part of composite filtering film (111),；The composite filtering film (111) includes The filter layer (115) and lining (116) that all-round fastness combines, the supporter (112) is porous structure, the composite filtering film (111) lining (116) is combined with the supporter (112) all-round fastness；It is described to recoil on plate membrane filtration membrane (110) Lower both sides are sealed as diaphragm seal side (113), and it is film to be opened at left and right sides of the plate membrane filtration membrane (110) that recoils Piece opens side (114)；The right and left of multiple plate membrane filtration membranes (110) that recoil respectively with the box that draws water (120) Box side wall (121) inside circumference that draws water is poured together by the pouring layer (130) being located in the box that draws water (120), described to pour The box inner cavity (123) that draws water, the plate membrane filtration membrane that recoils are equipped between layer (130) and the box end wall (122) that draws water (110) at least one open side (114) and described at least one box inner cavity (123) unicom that draws water, set on the box that draws water (120) There is at least one unit production water interface (124) with described box inner cavity (123) unicom that draws water.

The supporter (112) be it is any can be with the porous body of conducting fluid, including felt, net, " sandwich cloth " or it is multiple It closes, thickness is between 1-6 millimeters.Smaller support body thickness can influence the flowing of drainage, and excessive support body thickness can increase The occupation of land of blooming unit.

Distance is between 2-10 millimeters between the two neighboring plate membrane filtration membrane (110) that can recoil.Smaller film Piece spacing may cause aggregation of the sludge between diaphragm, excessive diaphragm spacing that will increase the occupation of land of film unit.

The mode combined closely between the filter layer (115), lining (116) and supporter (112) is that glue is compound, warm Compound and ultrasonic bonding mode at least one.Due to the filter layer (115), lining (116) and supporter (112) it Between combine closely so that the diaphragm can be resistant to Liquid backwash.

Referring to Figure 4 and 5, the tablet film filter (200) that can recoil includes multiple plate membrane mistakes that recoil longitudinally being superimposed Unit (100) and two end plates (210) are filtered, is equipped at least one end plate (210) and is connect with multiple unit production water It is close to produce water interface (212) with the water producing pipe and at least one device being arranged on end plate for the water producing pipe of mouthful (124) sealing unicom Seal unicom；Recoil tablet membrane filter unit (100) and the end plate (210) are equipped with the fixation for being fixed to each other Hole (400), multiple screw rods and nut recoil tablet membrane filter unit (100) and described two end plates (210) pass through by multiple Multiple mounting holes (400) are fixed to each other.

The plate membrane filtration membrane that recoils in the multiple tablet membrane filter unit (100) that recoils longitudinally being superimposed (110) there is relative dislocation in the direction vertical with diaphragm.The relative dislocation can increase the disturbance of membrane surface flushing air water stream, increase Blooming surface washing effect, thus diaphragm spacing can be reduced, improve film pack completeness.

In use, the tablet film filter (200) that can recoil by described in immerses in liquid to be filtered, filtering liquid is in gravity Under promotion, or in the case where described device production water interface (212) applies negative pressure promotion, filtered through the composite filtering film (111), through institute The box inner cavity (123) that draws water described in the entrance of supporter (112) water conservancy diversion is stated, then water is produced through the unit production mouth of a river (124), water producing pipe and device Interface (212) output.That can recoil, tablet film filter (200) bottom is aerated, and realizes the flushing to film surface.

With the only surrounding of filter membrane in known technology compared with the mode that support plate is bonded or welded, due to it is described recoil it is flat Composite filtering film (111) lining (116) is combined with the supporter (112) all-round fastness in plate membrane filtration diaphragm (110), institute It states the tablet film filter (200) that can recoil and Liquid backwash may be implemented.

Compared with using the mode of support plate between two filter membranes in known technology, the supporter (112) can be with Significantly reduce plate membrane filtration membrane (110) thickness that can recoil.Therefore the filling of tablet film filter (200) that can recoil Density higher.It is described to recoil since the supporter (112) unit area cost is far below classic flat-plate membrane support plate Tablet film filter (200) manufacturing cost is lower.

Due to the plate membrane filter membrane that recoils in the multiple tablet membrane filter unit (100) that recoils longitudinally being superimposed Piece (110) has significant disturbance in the gas-liquid flow for vertically to there is relative dislocation, being accordingly used in washing away film surface, thus improves punching Brushing effects, reduction can recoil the spacing between plate membrane filtration membrane (110), further increase packing density, reduce running cost With.
