Description

The big bath raio reverse-flow type of dyeing machine materials device

The utility model belongs to a kind of dyeing apparatus, refers in particular to a kind of dyeing machine with reverse-flow type materials device.

Traditional change materials device is arranged on an other change material cylinder of master cylinder, when changing material, dying material, auxiliary agent is added in the cylinder, adds a certain amount of cold water in addition, heats up again, the artificial stirring, up to whole dissolvings, then, directly import in the master cylinder with charge pump again, when dye addictive quantity is big, once all dissolvings must be at twice, change material 3 times, reinforced, the time of cost is a lot, cold water also will repeatedly be heated, and owing to be in course of adjustment, the solution in the master cylinder can constantly increase, destroy the bath raio stability with pollutant, had a strong impact on dyeing quality.

The purpose of this utility model is the big bath raio reverse-flow type of a kind of dyeing machine of a design materials device, to simplify the operation course, saves time and the energy, improves dyeing quality.

Its main technical schemes comprises master cylinder and is positioned at the cage of master cylinder, on the top of master cylinder is cylinder cap, bottom at master cylinder connects circulation pipe, dye liquid pump is set on circulation pipe, between circulation pipe and master cylinder, commutator is set, it is characterized in that on circulation pipe, utilizing respectively return duct, overflow pipe to connect the material cylinder, in the material cylinder, agitator is arranged, wherein an end of overflow pipe and return duct is connected on the circulation pipe of dye liquid pump inlet side and outlet side, is connected return valve and ratio charging valve respectively on overflow pipe and return duct;

The upper end of overflow pipe extends the middle part in the material cylinder, forms overfall; Between return duct and overflow pipe, charging valve is set; On the overflow pipe of ratio charging valve both sides, connect check valve and charge pump respectively;

Connect the lever of uncapping on cylinder cap, the outer end of the lever of uncapping is connected with the cylinder of uncapping that is installed on master cylinder outer wall bottom; Side wall upper part at master cylinder connects overflow valve and retainer cylinder; Bottom in master cylinder is provided with heater; On cage, can place through axle or cheese; On commutator, connect reversing cylinder.

But the utility model has the advantages that and utilize stabilizer bath ratio behind this device, because with the liquid backflow feed cylinder in the master cylinder, after the dyestuff dissolving in the material cylinder, deliver in the master cylinder again, in wholeization material process, be in same pressure all the time, with the state of the art of concentration, guaranteed that pollutant and dyestuff grammes per square metre than constant, have improved the reliability of dyeing quality; In addition, when dye addictive quantity is very big, because in wholeization material process, backflow, flooding process constantly carry out, when utilizing the interior solution of master cylinder to come dissolution aids in a looping fashion, the concentration of material cylinder inner dye is very low, may be unsaturated, also can not exist the graininess dyestuff to enter master cylinder, cause defectives such as look flower, aberration, color dot; In addition, native system can be determined the time that ratio is reinforced in the characteristic of dying material, like this on dye the fast very shallow amount of sensitiveness dye well dying material to advance the concentration of master cylinder very low, can not produce the aberration of pollutant top layer and internal layer, reach slow purpose of dying even colouring.

Fig. 1 is a structure chart of the present utility model.

As shown in the figure:

On the top of master cylinder 22 is cylinder cap 1, bottom at master cylinder 22 connects circulation pipe 10, dye liquid pump 9 is set on circulation pipe 10, at circulation pipe 10 and 22 of master cylinders commutator 12 is set, on circulation pipe 10, utilize return duct 24, overflow pipe 25 to connect material cylinder 2 respectively, in material cylinder 2, agitator 20 is arranged, wherein overflow pipe 25 is connected on the circulation pipe 10 of dye liquid pump 9 inlet sides and outlet side with an end of return duct 24, is connected return valve 3 and ratio charging valve 7 respectively on overflow pipe 25 and return duct (24).

The upper end of overflow pipe 25 extends the middle part in the material cylinder 2, form overfall 19, at return duct 24 and 25 of overflow pipes charging valve 4 is set, on the overflow pipe 25 of ratio charging valve 7 both sides, connect the check valve 8 and the charge pump 6 that is used to feed in raw material that are used to prevent the liquid reverse flow respectively, on cylinder cap 1, connect the lever 17 of uncapping, the uncap outer end of lever 17 is connected with the cylinder 16 of uncapping that is installed on master cylinder 22 outer wall bottoms, when needing to open cylinder cap 1, start the cylinder 16 of uncapping, its piston rod elongation, open cylinder cap 1 by the lever of uncapping, the overflow valve 21 and the retainer cylinder 18 that is used to lock cylinder cap 1 that connect the liquid level that is used to control master cylinder 22 in the side wall upper part of master cylinder 22, on cage 23, can place through axle 15 according to actual instructions for use, or cheese 14, the bottom in master cylinder 22 is provided with heater 13, with the temperature of the dye liquor in the control master cylinder 22, on commutator 12, connect reversing cylinder 11, to drive commutator 12 commutation cycle.

During use, dying material, auxiliary agent (not shown) in the cover hopper of material cylinder top feeds the material cylinder automatically, the aqueous solution of its dyestuff is the principle of utilizing pressure differential, the return line flow of drawing through the dye liquid pump outlet in the master cylinder is to the material cylinder, end to the last liquid level of expecting cylinder, wait to expect that the interior solution of cylinder is after agitator 20 abundant stirring and dissolving, the first overfall 19 from the material cylinder of its lysate is through overflow pipe 25, charge pump 6, ratio charging valve 7, check valve 8 is sent into the import of dye liquid pump 9, again in dye liquor delivery side of pump input master cylinder, simultaneously, return duct is constantly drawn the solution in the master cylinder, send in the material cylinder, dying material in setting-up time in the handle material cylinder, after auxiliary agent dissolves fully, return valve 3 cuts out automatically, agitator stops to stir, open baiting valve 4, lysate in the material cylinder 2 is all imported in the master cylinder through charge pump 6, automatically open the cleaning valve on the material cylinder this moment, its raffinate is entered in the sewage disposal pipeline by blowoff valve 5, so far, once change material feed technology and finish above action, time, controls such as liquid level can automatically be carried out.
