Description
Technical field
The present invention relates to field of environment protection, and in particular to prevents the dampening assembly and apply the dampening assembly that film film is damaged
Filtration module.
Background technology
Ultrafiltration membrane is one of polymeric membrane for separation developed earliest.Ultrafiltration membrane is that a kind of aperture specification is consistent, nominal pore
Scope is less than 0.01 micron of micropore filtering film.Appropriate pressure is imposed in the side of ultrafiltration membrane, with regard to that can sift out less than aperture
Solute molecule, 10 nanometers of particle is more than to separate molecular weight more than 500 dalton (atomic mass unit), particle diameter.
The commercial Application of ultrafiltration membrane is quite varied, it has also become one of novel chemical unit operation.For separating, concentrating, pure
In metaplasia Tetramune, pharmaceutical products and food industry；The terminal being additionally operable in prepared by blood treatment, wastewater treatment and ultra-pure water
Processing unit.
In order to more easily purify sewage, waste water treatment box and the filtration module in treatment box are now have devised,
Filtration module includes the water-permeable pipe with permeable hole and the locating ring and the square film film that are staggeredly set on water-permeable pipe, fixed
The centre bore passed through for water-permeable pipe is both provided with the ring of position and on film film.Two adjacent locating rings snap connection mutually,
The film being disposed between film to be fixed, then film film will obtain the sewage water filtration in waste water treatment box after filtering
Water passes sequentially through the gap between locating ring, locating ring and water-permeable pipe, enters after the permeable hole on water-permeable pipe in water-permeable pipe.
In aeration, the water in treatment box pours continuous fluctuation because of gas, and drives film film to shake.Due to film film
Upper one end close to water-permeable pipe is fixedly clamped by the locating ring positioned at its both sides, therefore during the shake of film film, is determined on film film
The position that position ring clamps is extremely stressed, long-time, the Strength Mass at high-frequency this position of shake smashed wound film film,
This crosses drainage not only bad for film film is smooth, the leakproofness for being also easy to reduce between locating ring and film film.
The content of the invention
Present invention aims at the filtration module for providing the dampening assembly and application dampening assembly for preventing that film film is damaged,
When solving the shake of film film, the position that ring clamping is positioned on film film is extremely stressed, long-time, high-frequency shake
The problem of Strength Mass at this position of smashed wound film film.Therefore the present invention design prevent dampening assembly that film film is damaged and
Using the filtration module of the dampening assembly, by setting dampening assembly on the locating ring between adjacent another film film, with drop
Close to the jitter amplitude at the position of locating ring on low film film, and it is shaken into row buffering, be positioned with reducing on film film
The stress that the position that ring clamps is born, improves the Strength Mass that film film is clamped position, improves service life.
The present invention is achieved through the following technical solutions：
The dampening assembly for preventing film film to be damaged, including locating ring, are provided with damping group on the side wall of the locating ring
Part, the dampening assembly include sequentially connected telescopic rod and elastic parts, one end of the telescopic rod and the outer wall of locating ring
Connection, the other end of telescopic rod is connected with elastic parts, the axis of the telescopic direction of the elastic parts parallel to locating ring.
When film film is shaken, due to the setting of elastic parts, trembling close to the position of locating ring on film film is which reduced
Dynamic amplitude, and it is shaken and is buffered, reduce and the stress that the position of ring clamping is born is positioned on film film, improve soft
Piece film is clamped the Strength Mass at position, beneficial to the smooth leakproofness crossed drainage, improve between locating ring and film film of film film.
Telescopic rod can use mobile bar, sleeve and screw association or atmospheric pressure pole or screw rod and internal thread cylinder
Combination or linkage etc..Elastic parts can use the components such as spring, air bag, eyelet, rubber.
Further, the elastic parts includes damping spring, and contact block is both provided with the both ends of the damping spring,
Parallel to the axis of locating ring, its side wall is connected the axis of damping spring with one end of remotely located ring on telescopic rod.
Film film to locating ring swing when, one end on film film side wall close to locating ring is contacted with contact block, and is compressed
Damping spring, then by compression shock absorption spring into row buffering, is positioned what the position of ring clamping was born to reduce on film film
Stress.
Due to the setting of dampening assembly, film vibration of membrane amplitude is reduced；Therefore in order to improve film film aeration and incite somebody to action
The effect that the slag of surface deposition is shaken off, can improve the frequency of film film shake, then keep the aeration effect of script.
Further, the contact block is hemispherical, its planar ends is connected with damping spring.
The setting of contact block increases the contact surface between damping spring and film film, and prevents film film by damping bullet
The situation that spring scratches occurs.
Preferably, the damping spring is cylindroid helical-coil compression spring.
Further, the telescopic rod includes being sequentially connected the fixed cylinder and screw rod of simultaneously coaxial line, the cylinder of the fixed cylinder
Bottom is connected with locating ring, in the centre bore of one end insertion fixed cylinder of the screw rod, and is threadedly coupled with the centre bore of fixed cylinder,
The other end of screw rod is connected with elastic parts.
The contact position according to required adjustment film film and dampening assembly is easy in the setting of telescopic rod.Rotary screw can be complete
Into the adjustment of telescopic rod axial length.
Further, force application spring is provided with the centre bore of the fixed cylinder, the axis of the force application spring is parallel
In the axis of fixed cylinder, the centre bore bottom hole of its one end and fixed cylinder connects, its other end and close centre bore bottom hole on screw rod
End thereof contacts, and force application spring is in compressive state.
Force application spring is in compressive state, increases the pressure that the thread of screw rod is born in the axial direction, then prevents screw rod
The autorotation in aeration and situation about loosening occurs, improve the stability of length of telescopic bar locking.
Further, contact ball is provided between the screw rod and force application spring, close to centre bore bottom hole on screw rod
One end be provided with contact groove, be connected on the contact ball close to one end of force application spring with force application spring, contact the another of ball
In one end insertion contact groove.
The contact groove is half concave ball shape, its radius is consistent with the radius for contacting ball.
The setting of ball is contacted, so that the thrust from force application spring is obtained on axis is more stable for screw rod, makes screw rod as far as possible
The power being subject to is overlapped with its axis, then makes the thread of screw rod uniform force in the axial direction, during preventing thread discontinuity,
With prevent screw rod in aeration autorotation and the undesirable situation of the effect that loosens occurs.
Further, it is provided with threaded hole on the side wall of the locating ring, away from elastic parts on the telescopic rod
In one end insertion threaded hole, and it is threadedly coupled with threaded hole.
Dampening assembly and locating ring dismantling connection, easy to the maintenance in later stage of the invention.
Have using the filtering module of above-mentioned dampening assembly, including water-permeable pipe and several film films, the damping device
Several, and damping device and film film are staggeredly set on water-permeable pipe, the locating ring in two neighboring damping device is mutual
