Description
Technical field
The utility model belongs to milipore filter manufacturing equipment field, specifically a kind of casting solution preparation still.
Background technology
Casting solution preparation is the critical process that diffusion barrier manufactures, and many employing semi-hand half mechanically actuateds, exist certain gap with ideal technology flow process, directly affect film liquid and even quality of forming film at present.Existing preparing process Problems existing is mainly manifested in following aspect.
1, efficiency is low.Semi-hand half mechanically actuated easily consumes the more time in the processes such as stirring, deaeration and transhipment, thus reduces production efficiency.
2, stir uneven.Adopt manual stirring or stir in the container be separated with agitator, being often difficult to stir, the time evenly needing more to grow be reached.
3, temperature controls extensive.Preparation temperature is the key factor that macromolecular material dissolves, and preparation can ensure temperature in a water bath, keep temperature constant more difficult, and the existence of steam affects the quality of casting solution.
4, humid control is difficult.Mixed liquor because contact surface some moisture content and water vapour content cause surface condensation, can cannot enter the film making process of lower step, preparation container covers thin film helpful to isolated steam.
5, natural standing and defoaming.Traditional deaeration adopts standing and defoaming, rises to liquid level deviate from by bubble natural buoyancy, and because casting solution viscosity is high, bubble floating is slow, and fine gas bubbles floats just slower.
6, container film liquid transhipment.Traditional film liquid transhipment normally pours film liquid into transfer container from dispensing containers, generally vial or stainless steel cask, pour in membrane equipment, particularly humid air contacts, film liquid remains in a reservoir, the container easily problem such as fragmentation or damage with air to there is film liquid in this process again.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of casting solution to prepare still, its efficiency is high, stirs, temperature and humidity control is good.
For realizing above-mentioned technical purpose, the scheme that the utility model provides is: a kind of casting solution preparation still, this casting solution preparation still is the double-layer stainless steel structural container of band heat-insulation layer, conduction oil is filled between two-layer, electric heating tube and temperature probe are immersed in conduction oil, the PLC that temperature probe is prepared with casting solution in the thermometer of still outer wall and switch board respectively connects, electric heating tube is controlled to open and close by the PLC in switch board, the outer wall of casting solution preparation still is provided with the Pressure gauge of display cavity internal pressure, the top of casting solution preparation still is provided with charging aperture, observation window, nitrogen inlet, exhaust outlet, stirring motor, be connected with agitator in the cavity that the shaft of stirring motor stretches into casting solution preparation still, the bottom of casting solution preparation still is provided with the discharging opening be connected with tubular membrane film-making machine by carrier pipe.
The beneficial effects of the utility model are:
1, efficiency is high.The utility model mixes designs such as adopting frequency conversion is stirred, vacuum defoamation and high pressure nitrogen force feed, completes a casting solution preparation time greatly to shorten, and enhances productivity;
2, stir.According to material characteristic, VFC agitator speed, first at a slow speed, then middling speed, at a high speed last, realizes the uniform dissolution of material;
3, temperature automatic control.Preparation temperature is the key factor that macromolecular material dissolves, and the temperature measured according to temperature probe by PLC in switch board and design temperature regulate the opening and closing of electric heating tube, regulate casting solution to prepare still interlayer conduction oil temperature controls casting solution temperature in still;
4, humid control is good.Material adds each valve of rear casting solution preparation still, the mouth of pipe is closed, and be hedged off from the outer world, water or steam cannot contact with material, avoids casting solution condensation phenomenon to occur;
5, negative pressure of vacuum deaeration.By certain negative pressure of vacuum, accelerate the rate of climb of bubble particularly fine gas bubbles, therefore deaeration is fast, and thoroughly;
6, high pressure nitrogen force feed film liquid.Casting solution preparation still need not be opened, directly with high pressure nitrogen pressurization, by material liquid outlet and Cemented filling in membrane equipment, therefore continuously, fast, with air exclusion, noresidue.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
The present embodiment provides a kind of casting solution to prepare still, this casting solution preparation still is the double-layer stainless steel structural container of band heat-insulation layer, as depicted in figs. 1 and 2, conduction oil 2 is filled between two-layer, electric heating tube 9 and temperature probe 3 are immersed in conduction oil 2, casting solution preparation still outer wall establishes thermometer 12 to observe temperature in the kettle, the temperature measured according to temperature probe 3 by PLC in switch board and the temperature of setting regulate the opening and closing of electric heating tube 9, control casting solution temperature in still by regulating casting solution preparation still conduction oil temperature.The outer wall of casting solution preparation still is provided with the Pressure gauge 11 of display cavity internal pressure; the top of casting solution preparation still is provided with charging aperture 5, observation window 6, nitrogen inlet 10, exhaust outlet 13, stirring motor 8; be connected with agitator 4 in the cavity that the shaft 7 of stirring motor 8 stretches into casting solution preparation still; the bottom of casting solution preparation still is provided with the discharging opening 1 be connected with tubular membrane film-making machine by carrier pipe; a filter can be added at discharging opening 1 if desired, filter the particle in casting solution or block.
When the utility model uses, raw material is put into casting solution preparation still chamber from charging aperture 5, successively can add in batches according to technological requirement, again according to reaction requirement during mixing, the conduction oil 2 controlled in electric heating tube 9 pairs of casting solution preparation still interlayers heats, and in conjunction with thermometer 12 show by the temperature data of temperature probe 3 Real-time Collection, control heat time and heating intensity, thus it is temperature required to make casting solution prepare acquisition in still chamber.Mixed process drives agitator 4 pairs of compounds to be uniformly mixed by stirring motor 8 by shaft 7.After mixing, reaction terminate, the heating of electric heating tube 9 can be stopped as required, exhaust outlet connects vacuum device and provides negative pressure in casting solution preparation still chamber, compound in auxiliary casting solution preparation still chamber carries out deaeration process, after completing, passing into nitrogen by nitrogen inlet 10 in casting solution preparation still chamber and opening discharging opening 1, compound is assisted to discharge casting solution preparation still, by entering next operation after filter.
