Summary of the invention
The purpose of this utility model provides a kind of equipment for preparing hollow fiber ultrafiltration membrane, and this equipment can improve the production efficiency of hollow fiber ultrafiltration membrane, guarantees product quality, reduce production costs, and easy to operate.
The purpose of this utility model realizes by following scheme: a kind of equipment for preparing hollow fiber ultrafiltration membrane, the main element of equipment comprises doughnut shaped device, spiral filament forming machine and casting machine, the doughnut shaped device is made up of stirring and dissolving still, filter, natrual ageing still, spinneret, spiral filament forming machine comprises coagulating tank, winding-roller and wrapping wire variable frequency reducer motor, casting machine comprises centrifugal casting variable frequency reducer motor, carrier frame plate and resin container, connect by pipeline between the said equipment parts, it is characterized in that:
The quantity of A, natrual ageing still is 3;
B, between natrual ageing still and spinneret, increase the cascade filtration device;
C, spiral filament forming machine are the two rollers of twin shaft, use variable frequency reducer motor.
The quantity that increases the natrual ageing still can obviously be enhanced productivity, and the output of equipment rises to original four times.The purpose that increases the cascade filtration device is to make feed liquid obtain sufficient purification from being dissolved to spinneret, thereby has improved the quality of doughnut, and the cascade filtration device adopts filter.Spiral filament forming machine uses variable frequency reducer motor to realize infinitely variable speeds.Like this can be according to the kind and the technological requirement of product, select out best rotating speed, transform the two rollers of twin shaft as by original single roller or coaxial pair of roller, single roller changes two rollers into and mainly enhances productivity, reduce and produce maintenance cost, coaxial pair of roller changes the two rollers of twin shaft into, makes operation simpler, easy, flexible, overcome operating difficulties, wayward, waste product problem how.
In the technique scheme, the connecting line between the part of appliance adopts the clamp connection of health grade stainless steel pipe part.Such improvement is to avoid pipeline inner living residual, has improved sealing property, has reduced leakage, and pipeline generally adopts the common stainless steel pipe part to be threaded in the prior art.
In the technique scheme, the inner surface of stirring and dissolving still and natrual ageing still carries out polishing.The purpose of doing like this is greatly to improve the fineness of inner surface, and making feed liquid be difficult in the still inwall in process of production has residually, and feed intake not residually to influence the shoddy of current feed liquid because of what arranged last time at every turn, cleans also to be very easy to.
In the technique scheme, the connected mode of casting machine and other equipment is a separate assembling.Casting machine changes separate assembling into by original overall structure, topmost purpose is the resonance that produces in the running when thoroughly having solved running part and the body one influence to equipment life and product quality, avoids being easy to generate in trembling for a long time tired fracture of wire phenomenon.Simultaneously, the cost of device fabrication descends, and manufacturing process is simple, installs, maintaining is also more convenient.
In the technique scheme, the carrier frame plate of casting machine changes into slatted by original disc type.Save material and processing charges like this, alleviated weight, saved power.Control section has used variable-frequency motor, has removed brake apparatus, makes machinery can both reach smooth transition in startup and stopped process.Simplified mechanism like this, also improved service life simultaneously.
The utility model has the advantages that: 1, improved production efficiency and product quality; 2, reduced production cost; 3, simple to operate, easy, flexible, maintaining is convenient, the service life of having improved equipment.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing 1 is this preparation milipore filter device structure schematic diagram, the main element of equipment comprises doughnut shaped device, spiral filament forming machine and casting machine (15), and the doughnut shaped device comprises stirring and dissolving still (1), accurate filter (2), natrual ageing still (3), filter (4), spinneret (5); Spiral filament forming machine comprises coagulating tank (6), winding-roller (7), wrapping wire variable frequency reducer motor (8).
Accompanying drawing 2 is the structural representation of this preparation milipore filter equipment casting machine, and casting machine (15) comprises centrifugal casting variable frequency reducer motor (9), transmission device (10), carrier frame plate (11), No. 1 assembly jig (12), resin container (13) and No. 2 assembly jigs (14).
The stirring and dissolving still is made up of pot cover, stack shell, chuck, agitator, frequency conversion reductor, transmission device and support, vesselseals, and whole cooker body and parts all adopt the stainless acid resistant steel plate to form.
This preparation milipore filter equipment carries out work in constant temperature, material drops into stirring and dissolving still (1) and carries out the agitating heating processing, and whipped form is that pot is wheeled, and the material heating is that electric conduction oil adds thermal material again by heat tape heating conduction oil.Cascade filtration is carried out by accurate filter (2) in material heating back, enter again and carry out the deaeration processing in 3 groups and the natrual ageing still (3) together, deaeration processing time 〉=48 hour, treated material liquid later enters filter (4) and carries out the one-level filtration again, the back is sprayed silk by pipeline to spinneret (5) extruding, the silk of ejection directly splashes into coagulating tank (6) cooling and shaping, drives silk uniform winding that winding-roller (7) will finalize the design on winding-roller (7) by wrapping wire variable frequency reducer motor (8).Silk on the winding-roller (7) is restrainted into a branch of from the cross section incision after reaching some specifications, the silk that bundle is good is placed in the water and is soaked, soak with glycerine again after the immersion and extract, make asymmetric semi-transparent film hollow fibre filament, again these hollow fibre filaments are adopted the method for tubulation layout, pack in the special container, use No. 1 assembly jig (12) again, No. 2 assembly jigs (14) are fixed on the carrier frame plate (11), through centrifugal casting variable frequency reducer motor (9) spun dry glycerine, dry back glue end socket, pour into a mould with resin again, wash afterwards, by having made hyperfiltration membrane assembly after the check.
