Description

DETAILED DESCRIPTION OF THE INVENTION The present invention enables a multi-tank dyeing machine to be used as a single dyeing machine or multiple dyeing machines depending on the amount of processing. Conventional multi-tank type systems have the disadvantage of lacking beam uniformity because each tank is connected in series by piping or in series with bypass.

In view of the above, the present invention enables complete parallel operation and improves level dyeing properties and finished texture.

In other words, the present invention provides a first header on the distribution side that integrates a plurality of dyeing tanks storing objects to be treated and one end of each pipe for injecting the dye solution into all the tanks, and one end of each pipe for circulating the dye solution in all the tanks. A large dye solution for all tanks, consisting of a first header on the circulation side that collects the dyes, a gate valve provided for each of the pipes, and a pipe conveyed between both headers via one beam liquid circulation pump. circulatory system and
Furthermore, a second distribution side that acts on some of the plurality of dyeing tanks
It consists of a header, a second header on the circulation side, a gate valve, and a small dye solution circulation system for some dyeing tanks, which is equipped with one beam solution circulation pump.

Next, an explanation will be given based on an embodiment shown in the drawings.

In the figure, 1 is a dyeing tank, and one carrier 3 is stored inside.

Seven pieces of cheese 4 are compressed and loaded into the carrier 3, and the presser lid 5
It is fixed in place. 2 is a dyeing tank lid equipped with a quick tightening device, which is opened to enable attachment and detachment of the carrier 3.

6 is a safety valve, 7 is a pressurization valve (compressed air), 8 is a pressure gauge in the pot, 9 is a liquid level gauge, 10 is an exhaust valve, 11 is an overflow valve,
A and B are beam liquid circulation pipes, Av and Bv are gate valves, and there are multiple dyeing tanks of the same structure equipped with such devices, five in the example (1, B, m, W, V). are installed in parallel.

Adjacent tanks are connected via pressure equalizing valves 12. The pressure equalization valve is for equalizing the tank liquid level. AH is the first header on the injection side that distributes the beam liquid to all tanks, and piping A is distributed from this to each tank. BH is a first header on the circulation side where the beam liquid of all the tanks is collected, and the pipes B of each tank are collected at this header. P is the first pump for circulation, the discharge amount of which is sent to the first header AH, and the suction side is sent to the first header BH.
The lotus is connected through pipes A, B, respectively. ah is W
A second header on the injection side that distributes the liquid to both the tank and the V tank passes through both tanks, and a second header on the circulation side that also collects the liquid in both tanks is connected to the first header. - Similarly, the dye liquid circulation pump P' is connected to the pipes a, q through the pipes a, q. av and bv indicate gate valves on the second header side. Sho 13
, 13' are flow control valves, and 14, 14' are heat exchangers. The first header side constitutes a large beam liquor heating and circulation device, and the second header side constitutes a small dye liquor heating and circulation device.

As described above, in the present invention, when dyeing one color in all tanks, only one set of large liang liquid circulation system is operated, and when used as two dyeing machines, up to 3 large liang liquid circulation systems are operated. Due to the circulation system, the remaining 2 or 1 pots use a small beam circulation system, and the dye solution from each tank is collected in the hetsuda, or distributed by the hetsuda respectively, so that high-quality dyeing can be achieved in parallel operation. In addition to being able to achieve uniform dyeing, it is possible to dye different colors at the same time using large and small dye solution circulation systems, and it is possible to provide a dyeing device that can reduce pump capacity and save energy as well as labor and rationalization. .

The flow direction of the dye solution is the direction of the arrow shown in the figure (normal blood flow → OUT).
), but it is of course possible to flow the dye solution in the opposite direction of the arrow if the pump can be operated reversibly (for example, by switching the rotation direction in a bag pump or using a pump with a sliding valve). .
