Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical package dyeing treatment apparatus for performing a low bath ratio treatment with a gas-liquid mixed fluid.

[0002]

[Prior art and its problems]

In a conventional vertical package dyeing processing apparatus, as shown in FIG. 3, a package fiber product P such as cheese stacked on each spindle 6 of a carrier 3 is completely treated in the processing tank 2 with a processing liquid L. Holding the treatment liquid surface S so that it is immersed in
Processing such as dyeing was performed by switching the circulating processing solution from inside to outside of cheese and from outside to inside of cheese. Therefore, the bath ratio was 1:20 or more, and the consumption of energy accompanying heating / cooling of the processing solution as well as dyes and chemicals was enormous.

Therefore, although energy saving has been promoted by the oil shock, the recent low bath ratio processing method lowers the processing liquid level S in the processing tank 2 and increases the winding density and capacity of the fiber cheese. However, 1: 6 was the limit for lowering the bath ratio.

An object of the present invention is to promote a further lower bath ratio in the treatment of packaged textile products.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a vertical package dyeing apparatus of the present invention is a dyeing processing method in which a carrier having a large number of spindles stacked with packaged fiber products such as cheese is mounted in parallel. A tank, an inner space of the carrier, and a processing tank that is an outer space of the carrier are communicated by an airflow circuit having a blower, and a processing liquid separated from an airflow after flowing through the package fiber product is stored. A treatment liquid circulation path was formed from the liquid reservoir to the spray nozzle inserted into the discharge-side airflow circulation path of the blower via a pump and a heat exchanger. It is possible to introduce the airflow discharged from the blower into the internal space of the carrier (in / out type) or the type to introduce it into the processing tank that is the external space of the carrier (out / in type). Two types are used properly according to the type of product and the processing content.

[0007]

In the type in which the air flow discharged from the blower is introduced into the internal space of the carrier, the atomizing processing liquid is supplied from the spray nozzle while the air flow is supplied to the internal space of the carrier through the air flow circulation path. A gas-liquid mixed fluid is generated. After the gas-liquid mixed fluid returns radially from the inside to the outside of the package fiber product stacked on the spindle of the carrier, the airflow is returned to the blower from the suction-side airflow circuit, and the processing liquid is connected to the liquid reservoir. The circulated processing liquid is circulated and supplied to the spray nozzle via a pump and a heat exchanger.

In the type in which the air flow discharged from the blower is introduced into the processing tank, which is the external space of the carrier, the atomizing processing liquid is sprayed from the spray nozzle while the air flow is introduced into the processing tank through the air flow circulation path. Is supplied to generate a gas-liquid mixed fluid. This gas-liquid mixed fluid circulates the packaged textile products stacked on the spindle of the carrier from the outside to the inside in the radial direction, and then the air flow flows down in the spindle and is circulated to the blower from the suction side air circulation circuit. The liquid is circulated and supplied from the treatment liquid circulation path connected to the liquid reservoir to the spray nozzle via a pump and a heat exchanger.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an in-out type vertical package dyeing and processing apparatus 1, which is a vertical cylindrical hermetically sealed processing tank 2, and a carrier 3 that is loaded into and out of the processing tank 2,
It has a blower 4 and a charging tank 5 disposed outside the processing tank 2.

An openable and closable lid 2a covers the upper portion of the processing tank 2, the bottom has a slow funnel shape, and a processing liquid reservoir 2b is formed below the center of the bottom. The carrier 3 is formed by arranging a large number of spindles 6 stacked with packaged fiber products P such as cheese in parallel, and the lower part of the carrier 3 is a hollow base 3a. The inside of the base 3a communicates with the inside of each spindle 6, and the base 3a serves as a header for distributing the gas-liquid mixed fluid to each spindle 6. An inlet opening 7 for introducing a gas-liquid mixed fluid is formed at the center of the lower surface of the base 3a. Also, on the lower side wall of the processing tank 2,
A pipe 8 is provided to penetrate in the horizontal direction. The inner end of the pipe 8 extends to the center of the processing tank 2, and then is bent upward in the vertical direction to open upward as an outlet opening 8 a for the gas-liquid mixed fluid. I have. The inlet opening 7 of the base 3a of the carrier 3 is detachably connected to the outlet opening 8a.

A bracket 9 extending outward in the horizontal direction is fixed to the outer wall surface of the processing tank 2, and a blower 4 driven by a motor 10 is installed on the bracket 9. The suction port 4a of the blower 4 is connected to an outlet opening 2c protruding from the outer wall surface of the processing tank 2 at a substantially intermediate position in the height direction of the processing tank 2. The discharge port 4b of the blower 4 is connected to a vertical end 8b of a pipe 8 extending outside the processing tank 2. Then, an air flow circulation path A is formed in the route of blower 4 → discharge port 4b → pipe 8 → carrier 3 base 3a → spindle 6 → processing tank 2 outlet opening 2c → suction port 4a → blower 4.

A spray nozzle 11 is inserted downstream in an elbow portion 8c in the middle of the pipe 8. The spray nozzle 11 is connected to the processing liquid reservoir 2b by a processing liquid circulation path B. In the treatment liquid circulation path B, in order from the treatment liquid reservoir 2b side,
A circulation pump 13, a heat exchanger 14, and a regulating valve 15 are provided.

The charging tank 5 is for dissolving and stirring the dyes and auxiliaries and introducing them into the processing tank 2. Inside the charging tank 5, a steam pipe 16 and a mixer 18 rotated by a motor 17 are arranged. The charging tank 5 is connected to the processing liquid reservoir 2 b by a supply path 19, and a pump 20, a check valve 21, and an adjustment valve 22 are provided in the supply path 19.

The processing of the package fiber product P by the processing device 1 is performed as follows. First, the lid 2a of the processing tank 2 is opened, the carrier 3 is loaded into the processing tank 2, and then the lid 2a is sealed. Next, the pump 20 and the regulating valve 22 are operated to store a fixed amount of the processing liquid L in the processing liquid reservoir 2b, and the blower 4 is driven to flow an air stream from the inside to the outside of the textile P at a high pressure. At the same time, the circulation pump 13 and the heat exchanger 14 are driven to inject the processing liquid L at a predetermined temperature from the spray nozzle 11 into a high-pressure airflow. A gas-liquid mixed fluid of air and mist treatment liquid is introduced into each spindle 6 from the pipe 8 through the base 3 a of the carrier 3, and is jetted out from a number of holes on the peripheral surface of the spindle 6 to the inside of the textile product P. From the outside and dyes the textile P in the process. The processing liquid L blown from the outer peripheral surface of the product P flows down and accumulates in the processing liquid reservoir 2b, and is again supplied from the spray nozzle 11 via the processing liquid circulation path B.

The above embodiment is an example of a so-called in-out type in which the air flow is made to flow from the inside to the outside of the packaged textile product P, but conversely, an out-in type in which the air flow is made to flow from the outside to the inside is similarly processed. Is possible. FIG. 2 (A)
(B) is a dual-purpose processing device 1'that can switch between in-out and out-in. In this device 1 ′, a pipe 2 detachably connected to an inlet opening 7 of a carrier 3
5 is disposed rotatably around the center line of the processing tank 2. The pipe 25 is connected to a switching cylinder 28 via a shaft 26 and a link 27, and is configured such that the pipe 25 makes a half turn by the operation of the cylinder 28. In the lower side wall of the processing tank 2, an inlet opening 29 and an outlet opening 30 are provided.
The pipes 25 are formed so as to face each other with an angle difference of °, and the pipe 25 is selectively connected to the inlet opening 29 or the outlet opening 30.

The outlet opening 30 is connected to the inlet opening 29 via a pipe 31, a liquid reservoir 32, a pipe 33, a blower 4 and a pipe 34.
And these form an air circulation circuit A. Further, the processing liquid reservoir 32 is connected to the spray nozzle 11 inserted into the pipe 34 by the processing liquid circulation path B via the pump 13, the heat exchanger 14, and the adjustment valve 15.

This dual-purpose processing device 1'is
By alternately switching out and out-in, more uniform processing is possible. In in-out processing,
As shown in FIG. 2A, the mist-like treatment liquid is supplied from the spray nozzle 11 to the air flow discharged from the blower 4 to form a gas-liquid mixed fluid, and this gas-liquid mixed fluid passes through the pipe 25 and the carrier 3
Is supplied to the spindle 6. The gas-liquid mixed fluid that has exited from the plurality of holes on the outer peripheral surface of the spindle 6 flows through the package fiber product P in the radial direction from the inside to the outside, and flows into the processing liquid reservoir 32 through the pipe 31. The airflow is further sucked into the blower 4 through the pipe 33 and is circulated to the carrier 3 again. After the treatment liquid is temporarily stored in the treatment liquid reservoir 32,
The fuel is circulated and supplied to the spray nozzle 11 via the pump 13, the heat exchanger 14, and the adjustment valve 15.

In the out-in process, the pipe 25 is rotated by a half turn as shown in FIG. As a result, the gas-liquid mixed fluid supplied into the processing tank 2 from the inlet opening 29 flows through the package fiber product P from the outside to the inside in the radial direction, and the package fiber product P is processed in this process. The gas-liquid mixed fluid flowing into the spindle 6 flows into the processing liquid reservoir 32 through the pipe 31. The airflow and the processing liquid are then circulated and supplied to the inlet opening 29 of the processing tank 2 in exactly the same manner as in FIG. In this way, by reversing the flow direction of the gas-liquid mixed fluid, the diffusion of the processing liquid to the package fiber product P can be averaged, and more uniform processing is performed.

If a heating means for heating the air flow from the blower 4 is provided in the air circulation circuit A, the mist-like treatment liquid can be fixed to the textile P by hot air.

[0020]

As described above, according to the present invention, since a gas-liquid mixed fluid containing a mist-like treatment liquid is caused to flow through a package fiber product in a treatment tank, the treatment is performed in a small amount, which is a limitation of the conventional art. Further, a low bath ratio of about 1: 6 is further promoted to enable an ultra low bath ratio of 1: 3 or less.
