Description

[Detailed description of the invention] (Industrial application field) This invention is a fabric cleaning device in which a long fabric is guided into a cleaning tank with an open top, and the fabric is repeatedly dipped in a cleaning solution for cleaning. It is used for continuous washing of fabrics after scouring, bleaching, dyeing, resin processing, etc.

(Prior Art) As a fabric washing device, a lower guide roller is provided at the bottom of a washing tank with an open top, and an upper guide roller is provided above the surface of the cleaning liquid in the washing tank. It is known that a long piece of cloth is wound around a guide roller in a zigzag pattern and transported, and the cloth is washed by repeatedly immersing it in a washing liquid in a washing tank. Conventionally, in order to heat the cleaning liquid,
Multiple steam injection pipes were installed near the bottom of the cleaning tank, and high-temperature steam was injected from these steam injection pipes.

(Problem to be solved by the invention) The cleaning liquid in the cleaning tank is stirred by the fabric passing through the cleaning liquid and the steam injected into the cleaning liquid from a steam injection pipe. Since the washer was installed near the bottom of the washing tank, the stirring action was relatively weak, so even if the dirt and foreign matter adhering to the surface of the fabric were removed, the dirt and foreign matter present inside the fabric could be removed. could not be excluded.

This idea attempts to improve the cleaning effect by changing the position of the steam injection pipe.

(Means for solving the problem) A pair of widthwise long fabrics that are placed in the vicinity of the liquid level on the side where the fabrics are led out from the cleaning liquid, sandwich the fabric F in the vertical direction, and spout steam diagonally upward. A steam injection pipe 5 is provided, and a rectifying plate extending in the vertical direction is fixed to this steam injection pipe. In addition, the interval between one set of steam injection pipes 5 is preferably 10 to 30 mm, and the depth below the liquid level is preferably 3 to 20 mm at the position of the ejection hole 4a.

(Function) Since the steam is ejected near the liquid surface, ripples are likely to occur due to the vibration of the cleaning liquid W, and the cleaning liquid W is violently agitated, and moreover, the steam is ejected in opposite directions, sandwiching the fabric F running in the vertical direction. As a result, strong vibrations are applied to the fabric F, and as a result, the cleaning effect is improved. A steam injection pipe is provided on the outlet side where the fabric F rises, and the steam is ejected diagonally upward, so the movement of the fabric and the ejected steam help each other, causing strong ripples and vibrations on the liquid surface, and further The propagation of these ripples and vibrations is restricted by the current plates, and the cleaning liquid is strongly stirred only between the front and rear current plates, thereby further improving the cleaning effect and reducing noise.

(Example) In the drawings, 1 is a cleaning tank, 2 is a lower guide roller, 3 is an upper guide roller, W is a cleaning liquid, the fabric F is hung on the upper and lower guide rollers 2 and 3 in a staggered manner, and the lower guide roller 2, it is immersed in the cleaning liquid W. Directly below the liquid level on both the front and back sides of the fabric F, from the lower guide roller 2 on the inlet side (left side in the figure) to the upper guide roller 3, two steam injection pipes 4 long in the width direction face each other with their injection holes 4a diagonally upward. It is set up as follows. Two rectifying plates 5 extending vertically are provided between these two steam injection pipes 4 in a facing manner. The current plate 5 is partially curved along the perforated surface where the injection holes 4a of the steam injection pipe 4 are provided, and is closely integrated with the current plate 5.
A widthwise long slit 5a communicating with the injection hole 4a is bored in this curved surface, and the steam injection pipe 4
The high temperature steam supplied to the fabric F passes through the injection holes 4a and the slits 5a and is ejected obliquely upward to both sides of the fabric F. On the other hand, below the fabric supply side of the upper guide roller 3, an upper steam injection pipe 6 long in the width direction is provided with its injection hole 6a facing the contact start point between the fabric F and the upper guide roller 3. An upper cover 7 is provided to cover the portion above the liquid level of the fabric F applied to the roller 3, and by positioning the lower end of this upper cover 7 below the liquid level, the interior of the upper cover 7 is formed into a steaming chamber.

In the above configuration, the high temperature steam supplied to the steam injection pipe 4 below the liquid level is ejected directly below the liquid level of the cleaning liquid W through the injection hole 4a of the steam injection pipe 4 and the slit 5a of the baffle plate 5, The cleaning liquid W is heated and the vicinity of the liquid surface of the cleaning liquid W is strongly vibrated to stir it. And rectifier plates 5 are placed above and below the steam injection pipe 4.
Since the cleaning liquid W is elongated, the propagation of vibrations and ripples of the cleaning liquid W caused by the jetting of steam is restricted, strong agitation occurs only between the front and rear baffle plates 5, and noise is reduced. In this embodiment, since the steam is ejected onto the fabric F below the upper guide roller 3, the fabric F is vibrated, the fabric F is reheated, and the steam is condensed into cleaning water, which causes the fabric to The cleaning of F is promoted, the outer periphery of the upper guide roller 3 is cleaned, and foreign matter such as fiber waste that tends to adhere to the upper guide roller 3 is washed off. Furthermore, since the steaming chamber is formed by the upper cover 7, the cleaning effect is further improved.

(Effects of the invention) This invention jets out steam diagonally upwards in opposite directions near the liquid level on both sides of the fabric on the side where it is drawn out from the cleaning liquid level, and by this jetting and the movement of the fabric. Since the propagation of the generated waves and vibrations is restricted by the front and rear rectifier plates, the cleaning liquid is locally strongly agitated in the area close to the fabric.
Therefore, the cleaning effect is significantly improved compared to the conventional device in which the steam injection pipe is provided at the bottom of the cleaning tank. Moreover, since steam is injected instead of air, the cleaning liquid can be heated, and the conventional steam injection pipe provided at the bottom can be omitted.
