Description

Open high temperature dyeing machine

The invention relates to a dyeing machine, in particular to an open high-temperature dyeing machine, which can make the cloth continuous dyeing operation.

Press, when the cloth is to be dyed, it must be placed in a dyeing machine, and the cloth inside the body is used to dip the cloth to achieve the purpose of dyeing.

1 is a schematic view showing the structure of a dyeing machine 80, which is generally covered with a body 81 and has a feeding opening 82 in front of the body 81. After the cloth C is placed, the cover 83 is closed. The cloth C is caused to circulate in the body 81 by the guide wheel 84 and the nozzle 85 so that the cloth C can be impregnated with the dye liquid 86 in the body 81.

However, the conventional dyeing machine 80, whether it is the long-tube type body disclosed in Fig. 1, or the dyeing machine of other types, has a common problem that the cloth C must be placed in the body 81, By using a heat exchanger 87 for heating, in the case of a high temperature dyeing machine, the temperature of the dyeing liquid must be maintained above 100 ° C, since the liquid at 100 ° C needs to be changed from a liquid phase to a gas phase. The latent heat is defined as heat of evaporation, and the heat of vaporization of water at 1 atm is 2.26 × 10 ⁶ J/kg. However, since the gas state is related to pressure, for example, water has a boiling point of 100 ° C at 1 atm.

For this reason, the conventional high-temperature dyeing machine must seal the body 81, and since the temperature is proportional to the pressure, the cover 83 must be closed by the cover 83 to form a closed space, so that the high-temperature dyeing liquid 86 is vaporized. This is the method currently used for dyeing cloth.

However, the biggest problem with the previous method of dyeing is that the cloth C can only be placed in the length of the body 81 at a time (for example, 50 to 80 meters). After the dyeing is completed, the body 81 must be cooled for several hours to normal temperature. The cover 83 can be opened to take out the cloth; then, a new cloth C is placed to be dip-dyed. After the cover 83 is closed, the body 81 must be reheated to change from normal temperature to high temperature to effectively infiltrate the cloth. Therefore, the cloth is placed and taken out, heated and cooled, and the temperature is continuously repeated, which not only wastes the time of picking and dropping, but also increases the temperature and reduces the waste of resources; therefore, there is still room for improvement.

The main object of the present invention is to provide an open high-temperature dyeing machine which utilizes a plurality of U-shaped tubular bodies to be connected to each other to form at least one U-shaped body for dyeing and to prevent When the dyeing liquid is heated above 100 °C, the U-shaped body is formed before and after vaporization, and the water level pressure difference (P=ρgh) is used to prevent the dyeing liquid from heating to a temperature exceeding 100 °C, and the liquid phase is changed. The back pressure of the gas phase, and the pressure is proportional to the high temperature set by the dyeing liquid, so that the height of the equipment (water level) can be set according to the dyeing temperature, so that the water level pressure can maintain the high temperature dyeing liquid over 100 ° C ~ 135 At °C, the back pressure is still not vaporized, and the non-closed design of the front and back body is connected, so that the cloth can be continuously dyed, without the need to repeatedly take, put, and raise and cool. In turn, it can improve the dyeing performance and save energy.

In order to achieve the above object, the technical means adopted by the present invention comprises: a dyed body, which is composed of a second U-shaped tube body, and whose height is greater than 10 meters, the content of which is dyed, and the dyeing liquid Maintaining in the second type U tube without overflowing; a front body is composed of a first U-shaped tube body, the front end of which is an open cloth introduction port, and the tail end is connected to the second U The front end of the tubular body is formed into a communication shape, the height of the first U-shaped tubular body is greater than 10 meters, the content of which is liquid, and the liquid is retained in the first U-shaped tubular body without overflowing; The body is formed by a third U-shaped pipe body, the front end of which is connected to the tail end of the second U-shaped pipe body, and forms a communication shape, and the tail end thereof is an open cloth outlet, the third The height of the U-shaped tube is greater than 10 meters, the content of which is liquid, and the liquid is held in the third U-shaped tube body without overflowing; and a heating device is disposed at the bottom of the second U-shaped tube body Zone, and heating the dye liquor to above 100 ° C; thereby, each body forms a continuous curved body and uses the front body and The pressure barrier layer formed by the water level inside the body causes the high temperature dyeing liquid in the dyeing body to be blocked by the water level pressure in the front and rear body, preventing the vaporization of the dyeing liquid heated by the high temperature, and forming the whole The closed container allows the cloth to be continuously dyed through the front body, the dyed body and the back body.

According to the pre-existing feature, the first, second and third U-shaped tubular bodies are connected in a continuous manner, and are connected by a curved arc tube, and the top surface of the curved arc-shaped curved tube is provided with a cover body, and a guide cloth is arranged inside. wheel.

By means of the above-mentioned technical features, the invention eliminates the dyeing method of the conventional closed high-temperature dyeing machine, and further adopts the open type body, and uses the water level difference pressure as a barrier layer for preventing high-temperature dyeing liquid vaporization, but the barrier layer system It is a liquid that does not hinder the circulation of the cloth. It can also be used as a cloth for cleaning or fixing the color to achieve synergistic effect.

First, referring to Figures 2 to 4, the open high temperature dyeing machine 70 of the present invention preferably comprises:

A dyed body 20 is composed of a second U-shaped tubular body 21 and has a height greater than 10 meters. The dyeing liquid D is built therein, and the dyeing liquid D is held in the second-shaped U-shaped tubular body 21 Not overflowing inside.

The front body 10 is composed of a first U-shaped pipe body 11, and its front end is open, and serves as the introduction port 12 of the cloth C, that is, the inlet port 12 does not need to be closed by the cover body, so that the cloth is closed. C is continuously advanced, and the trailing end 13 of the first U-shaped tubular body 11 is continued at the front end 22 of the second U-shaped tubular body 21, and a communication shape 50 is formed.

A rear body 30 is formed by a third U-shaped body 31, the front end 32 of which is connected to the tail end 23 of the second U-shaped tubular body 21, and forms a communication 50, and the tail end is an open cloth. The outlet port 33.

A heating device 40 is disposed in the bottom portion of the second U-shaped tubular body 21 for heating the dyeing liquid D to above 100 °C.

In this embodiment, the second U-shaped tubular body 21 further includes a main pump 60 and a delivery line 61, and the main pump 60 is connected to a dye supply unit 62. Thereby, from the bottom of the second U-shaped tubular body 21, the dyeing liquid D is sent to a higher position on both sides of the second U-shaped tubular body 21, so that the dyeing liquid D in the second U-shaped tubular body 21 is circulated up and down. Heating, so that the temperature in the entire second U-shaped tube 21 is averaged.

In addition, the first, second, and third U-shaped tubular bodies 11, 21, 31 are provided with a discharge port 63 at the bottom, and the first and third U-shaped tubular bodies 11, 31 are connected with a liquid supply unit and a pipeline (not shown) ), can not be described.

That is, the first, second, and third tubular bodies 11, 21, and 31 of the respective bodies are in the form of a continuous curved tube, but the internal dyeing liquid D and the liquid W system are each independent. The liquid W in this embodiment is included as water or a washing liquid or the like.

Since the pressure of the stationary fluid is P = ρgh, where ρg is a constant, h is the difference in liquid height; that is, the water pressure is proportional to its height. For example: water level difference of 10 meters high = 1kg water pressure, 30 meters high water level difference = 3kg water pressure, and so on, so as shown in Figure 4, if the dye solution W is not vaporized at 100 ° C , 1kg water pressure shall be required on both sides, and the water level difference h shall be 10 meters. Generally, the temperature of the high-temperature dyeing machine is at least 100 ° C. Therefore, the heights H of the first and third U-shaped tubes 11 and 31 of the front body 10 and the rear body 30 must be at least 10 meters. The U-shaped tube can accommodate a water level difference of 10 meters, and the pressure barrier layer formed by the water level pressure difference (h) in the front body 10 and the rear body 30 prevents the middle of the dyed body 20 in the middle. Dye D, vaporized due to temperature exceeding 100 °C. Moreover, the present invention utilizes water pressure to block vaporization. Therefore, the open high-temperature dyeing machine 70 of the present invention integrally forms a non-closed container, and the front and rear ends thereof are still open, so that the cloth C passes through the front body 10 → Dyeing body 20 → Rear body 30 is a continuous dyeing operation.

By means of the above-mentioned technical means, the invention eliminates the dyeing method of the conventional closed high-temperature dyeing machine, and uses the open-type curved pipe body to take the water level difference pressure as a gas to prevent the high-temperature dyeing liquid from changing from the liquid phase. A gas phase barrier layer, and the barrier layer is a liquid, which does not hinder the circulation of the cloth, and can be used as a cloth cleaning or fixing color to achieve the synergistic effect.

In addition, the cloth is continuously circulated and dyed, no need to stop the machine and the temperature of the dyeing liquid is heated and cooled, which not only reduces the standby time, but also saves energy consumption, and has the effect of improving productivity and reducing energy waste.
