The specific embodiment
By given accompanying drawing, can understand technical pattern of the present utility model.Can understand the summary of the invention that this is practical by accompanying drawing 3 and the attached Fig. 1 and 2 of 4 contrasts.Below in conjunction with the description of accompanying drawing, will and realize that the technical scheme of purpose is clearer to the purpose of this utility model by the specific embodiment.
One of specific embodiment please be joined and be read accompanying drawing 3 and 4.Two small trough dye liquor circulating device is made up of the dye liquor tank 1 and the dye liquor cycling mechanism 2 that comprise the first little staining bath 1-1 and the second little staining bath 1-2.
In the part of dye liquor tank 1, be divided into the first single-row little dye liquor tank 1-1 and the second little dye liquor tank 1-2.Two said little dye liquor tank 1-1 and 1-2 is wide and opposing parallel get together, and the width of two said little dye liquor tank 1-1 and 1-2 is greater than the length of underliquor guide roller (7).
In dye liquor cycling mechanism 2 parts,, be provided with the communicating pipe 2-1 that makes the first little dye liquor tank 1-1 and the second little dye liquor tank 1-2 be connected in the bottom of the first little dye liquor tank 1-1 and the second little dye liquor tank 1-2.Be provided with its length and the close feed tube 2-2 of the second little dye liquor tank 1-2 groove width on the top of the second little dye liquor tank 1-2 madial wall, on feed tube 2-2 and along it, be axially arranged with equally distributed 7 inlet opening 2-2-1; In the bottom of the first little dye liquor tank 1-1 madial wall, be provided with its length and the close liquid back pipe 2-3 of the first little dye liquor tank 1-1 groove width, on liquid back pipe 2-3 and along it, be axially arranged with equally distributed 7 hole for back flow 2-3-1 (asking for an interview accompanying drawing 4).Feed tube 2-2 is connected by advance liquid pipeline 2-4 and the diaphragm type infusion pump 2-5 that is located at its length direction middle part, and the side barrel cavity 3a of infusion pump 2-5 by screen pack 3-1 set in laggard liquid pipeline 2-6 and the filter vat 3 is connected, and the barrel cavity 3b that establishes the opposite side of screen pack 3-1 in the liquid back pipe road 2-7 of liquid back pipe 2-3 by being located at its length direction middle part and the filter vat 3 is connected, thereby constituted dye liquor closed loop peripheral passage.And infusion pump 2-5 also can be started or shutdown control by carrying out manually by the automatic control of controller 4 implementation work.Below filter vat 3 internal memory dye liquor liquid levels, be provided with TEMP transmitter 5, this transmitter 5 is by controller 4 control dye liquor heaters 6, with the temperature stabilization that guarantees dye liquor in the scope of technological requirement value.
Because the existence of communicating pipe 2-1 and liquid back pipe road 2-7, and the dye liquor liquid level in two little dye liquor tank 1-1 and 1-2 and filter vat 3 threes is equated, infusion pump 2-5 moves according to the program time of setting under controller 4 controls, via the dye liquor in the laggard liquid pipeline 2-6 suction filtration bucket 3, again through the liquid pipeline 2-4 that advances, feed tube 2-2 is injected in the second little dye liquor tank 1-2 by feed liquor aperture 2-2-1, and the dye liquor in the first little dye liquor tank 1-1 is in infusion pump 2-5 suction, and produce potential difference between the filter vat 3, the dye liquor in the first dye liquor tank 1-1 groove flows back to filter vat 3 through liquid back pipe road 2-7.At this moment, the dye liquor liquid level of the second little dye liquor tank 1-2 is higher than the dye liquor liquid level of the first little dye liquor tank 1-1, so make the dye liquor liquid level of two little dye liquor tanks obtain transient equilibrium through communicating pipe 2-1.The cyclic process that so goes round and begins again makes dye liquor vibration regularly in two little dye liquor tank 1-1 and 1-2, and very helps the infiltration dipping of dye liquor to fabric.
On filter vat 3, except TEMP transmitter 5 is housed, level sensing transmitter (not drawing among the figure) can also be housed.Accurately control liquid level by the level sensing transmitter, can guarantee that fabric passes through the uniformity (or claim fabric in dye liquor elapsed time uniformity) of dye liquor road through length, to guarantee to reduce aberration.Temperature, level sensing transmitter being placed on the filter vat 3, helping operative employee's supervision on the one hand, is transmitter owing to what adopt on the other hand, helps the interference antagonism of robot control system(RCS).
The length of feed tube 2-2 and liquid back pipe 2-3 is all made by the groove width that approaches two dye liquor tank (dye vat) 1-1 and 1-2, and feed liquor and return liquid (referring to accompanying drawing 4) therebetween all, make the whole breadth liquid stream of two little dye liquor tank 1-1 and 1-2 so on the one hand evenly, can effectively eliminate " blind area " of dye liquor balance on the other hand, zone outside the fabric edge also can obtain timely balanced exchange, thereby the dark difference in limit of DYED FABRICS is improved.
Experimental example discloses, and uses the utility model on novel huge dye jigger, and its yardage roll can reach Φ 1500mm, and the dye liquor total amount in two little dye liquor tanks only is 200kg, and the balanced exchange time only is 8min.Compared with the prior art, the utility model has greatly been saved the dye liquor consumption, has shortened the balanced exchange time, has improved the monovolume output of yardage roll.Shown bigger potential economic benefit.
