The rosin recovery filter method that uses this device is after earlier the resist printing wax on the batik figured cloth being returned with caustic soda, leave a large amount of saponification rosin in the waste water, to contain a large amount of saponification rosiny wastewater collections stores, in the input and in the tripping device, regulate the sour requirement of neutralization reaction by the pH value of regulating PH meter monitoring batik waste water, stir evenly batik waste water and acid with agitator simultaneously, with heater heats batik waste water, isolate the rosin suspended particle to greatest extent, again the rosin suspended particle is delivered to and carried out refinery filtration removal impurity and moisture in the High Temperature Furnaces Heating Apparatus, can carry out one or many cyclic high-temperature refinery according to this, utilize again up to the rosin purifying.Its technical process is that batik figured cloth caustic soda is moved back wax → contain saponification rosin wastewater collection pond → hold-up vessel → neutralization separation → high temperature refinery → filtration → high temperature refinery → filtration → mixing preparation → seal wax machine, its processing requirement: 1, caustic soda moves back wax: rosin is a kind of resinous acid, under the effect of caustic soda, " saponification reaction " can take place and form water-soluble rosined soap in it, thereby can be with its eccysis from the fabric.But saponification rosiny content is high in the waste water.2, collecting tank, hold-up vessel: every production one myriametre batik figured cloth, produce 15 tons approximately and contain saponification rosin waste water, if produce ten myriametres every day, the waste water total amount will need to collect, store up to 150 tons.3, neutralization separates: according to the acid-base neutralisation principle, adopt sulfuric acid the neutralization of the caustic soda in the waste water, and allow waste water be acid, make rosin separate out from water.Simultaneously, the waste water heat temperature raising is made the rosin of separating out nature agglomerated together and water sepn.Concrete way: saponification rosin waste water is heated under the condition of 40 ℃-85 ℃ of temperature, if sulfuric acid is regulated the pH value of waste water between 1-6, rosin will condense and water sepn naturally.4, high temperature refinery, filtration: the rosin of separating still contains moisture and other impurity of 20-30%, must handle moisture evaporation through the high temperature refinery, part of fuel is decomposed, and take out impurity and ash content through private filter.High temperature refinery temperature generally between 130 ℃-180 ℃, time 5-10 hour.Through twice refinery, filtration, just form " black rosin " that can utilize again.5, mixing preparation: the softening temperature of " black rosin " is too high, and acid number is lower, and is mobile poor during high temperature.For being applied in the batik production, must add a certain amount of high temperature oil increases its flowability again, can evenly saturating net when being suitable for printing wax.High temperature oil comprises: high temperature heat medium oil, high temperature grease or the like.Its well heater is made up of single or double heating tube, and single heating tube is made up of two weldless steel tubes, and there is the gap of 10 ~ 20MM the centre, and the sealed at both ends welding of interior pipe and outer tube connects with

flow to the pipe tail, enter the interlayer of second heating tube again through pipe connecting, in flow process with the pipe outside medium carry out heat exchange, enter the thermo oil boiler heating after proceeding to last root, so circulation.Principal feature is to strengthen heat exchange area, reduces thermal oil resistance to flow and energy dissipation, improves the efficient of heat exchange.Concrete principle of work is: according to the rosiny physico-chemical property, and sylvic acid C ₁₉H ₂₉COOH forms the sodium salt of water-soluble sylvic acid with caustic soda through saponification, many foams, the effect of soap is arranged, so this reaction is commonly referred to saponification reaction.In the process that the batik figured cloth is produced, rosin removed method from the fabric has formed saponification rosin by saponification reaction just.That is: C ₁₉H ₂₉COOH+NaOH → C ₁₉H ₂₉COONa+H ₂O.Saponification rosin is neutralized through adding acid, and make it keep acid, its reaction formula is: C ₁₉H ₂₉COONa+H ₂SO ₄→ C ₁₉H ₂₉COOH ↓+Na ₂SO ₄From batik waste water,, realized effective extraction rosiny way by adding the isolating mode of acid neutralization.When being warming up to 70-80 ℃ (being the rosiny softening temperature), the rosiny suspended particle will produce gathering formation solid and float on the water surface, will easily it be separated.The isolated suspended substance water content of institute is lower, is convenient to carry out purifying and refines, and is back to and produces, and has saved natural resources, simultaneously, and the also controlled and reduction of the CODcr value of the examination of sewage disposal.It is that opening for feed is arranged that described rosin reclaims filtration unit, steam jacket, supporting cover, motor, axle sleeve, deceleration device, driver, the chassis, slag notch, go out (wax liquid) material mouth, filter body, agitator, traverse baffle, doctor blade holder, wing, trim ring, sealing cover, filtering net, formations such as cylinder, it is that agitator is housed in filter body, traverse baffle, doctor blade holder and wing, outside filter body, be surrounded by steam jacket, chassis and loam cake are housed two ends respectively up and down at filter body, trim ring and sealing cover, driving stir shaft by motor by deceleration device and driver rotates, in interlayer, feed vapour or the water or the oil of certain temperature, batik waste water enters in the strainer from opening for feed, stir through stir shaft, rosin is in melting state, stir shaft is in rotary course, scraper scrapes filter screen with the wax liquid in the container, and overflow from discharge port, impurity etc. are deposited in the bottom of container, get final product scarfing cinder after opening bottom.This from batik waste water by extracting rosin apace.Simultaneously, the rosin that separation and Extraction is come out carries out refinery, filtration treatment again, can be back to production again, forms the recycling economy new model; The middle water of handling well can also be used for flushing the toilet, scrub ground and use the life of water and aspect such as production.Be ideal sewage disposal technology and isolated plant.
