Description

Hot air circulation system for dry chamber

The present invention relates to a hot air circulation structure of a drying chamber of a fiber heat processor (tenter), and more particularly, at the same time installing a vortex generation preventing plate at a side of a hot air outlet of a hot air supply fan installed inside a drying chamber of the fiber heat processor. Hot air supply fan is not a plurality of fans By installing a single fan in the center of the side wall of the heat treatment machine, the hot air sent to the inlet side of the hot air jet port is supplied evenly mixed without vortex generation and the temperature deviation of the hot air sent to each hot air jet nozzle (nozzle). This will increase the drying efficiency for the fabric by not generating at all.

In general, the fabric produced by the weaving machine is a post-process dyeing process and water washing process, the fabric contains a certain level of moisture. Thus, the fabric containing moisture is stored in a winding roll after the drying step after In this case, the fiber heat processor used in the drying step for drying the fabric is a drum drying type for drying the fabric by using the surface heat of the drum heated by an internal heating source, and the hot air is circulated into the drying chamber. Hot-air circulation drying type is proposed to dry the fabric by passing the fabric between the hot air in the state, but now the heat treatment of the hot air circulation drying type superior in terms of drying efficiency is mainly used.

The hot air circulation structure type heat treatment machine, which is widely used as described above, has a set of hot air jetting holes formed with a plurality of hot air jetting holes formed on the fabric side of the upper and lower fabrics inside the drying chamber through which the fabric supplied for drying is passed. It was to be able to dry the fabric by continuously spraying hot air to the fabric passing through a plurality of tanks repeatedly installed.

However, as described above, the heat exchanger of the hot air circulation drying type has a plurality of supply fans for supplying hot air to a plurality of hot air jet nozzles installed therein. Hot air is circulated and supplied. In this case, the hot air forcedly circulated in the manner of being sucked and discharged by the hot air supply fan forms a strong vortex at the upper side of the supply fan, resulting in uneven circulation speed of the hot air. In addition to obstructing circulation and supply, there was a problem that the drying efficiency of the fabric was lowered as a result of the temperature deviation of the hot air supplied to the hot air jet port.

Therefore, the purpose of this paper is that the strong vortex is formed in the upper part of the hot air supply fan installed in the drying chamber in the process of circulating the hot air to the hot air injector in the drying chamber as described above, so that the smooth circulation and supply of the hot air cannot be made. In addition, in order to solve the problems of the conventional hot air circulation drying type heat treatment machine, in which the temperature deviation of the hot air circulated is generated and efficient drying of the fabric cannot be achieved, a single hot air supply fan is installed on the inner wall of the drying chamber instead of a plurality of hot air circulation fans. At the same time, the vortex prevention plate is installed upright on the outlet side of the hot air supply fan to a certain height so that the vortices are not generated in the process of sending the hot air to the inlet side of the hot air jet as it circulates inside the drying chamber and prevents temperature deviation. The drying efficiency of the fabric It has a hot-air circulation drying chamber structure of the fibers heat-treated group to provide the number of days to.

In order to achieve the above object, in the drying chamber hot air circulation structure of the fiber heat processor according to the present invention, in the state in which a plurality of hot air jet nozzles (2) are installed in the drying chamber (1) of the fiber heat processor to be opposed to each other, Between the plurality of sets of hot air jets (2) In the drying chamber hot air circulation structure of the fiber heat processor which is allowed to pass through the hot air circulated by passing the fabric f, a single hot air supply fan is formed at the center of one side wall of the drying chamber 1.

(3) is installed, and a side of the outlet 32 of the hot air supply fan 3 is characterized in that the vortex generation preventing plate 4 having a predetermined width is installed upright at a predetermined height.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement the present invention.

1 is a front sectional view schematically showing an example of a heat treatment apparatus to which the hot air circulation structure according to the present invention is applied, and FIG. 2 is a side view schematically showing an example of a heat treatment apparatus to which the hot air circulation structure according to the present invention is applied, and FIG. 4 is a front cross-sectional view schematically showing an example of a heat treatment apparatus to which a hot air circulation structure is applied, and FIG. 4 is a side view schematically showing an example of a heat treatment apparatus to which a conventional hot air circulation structure is applied.

The configuration is that a single hot air supply fan (3) is installed in the center of one side wall in the drying chamber (1), and then a vortex generation preventing plate (4) is installed above the hot air supply fan (3), that is, one side of the outlet (32). It becomes one configuration.

The hot air supply fan (3) sucks the hot air supplied into the drying chamber (1) through the suction port 31 to be strongly discharged through the outlet 32 of the upper side of the hot air supply fan in the drying chamber (1) By being supplied into a plurality of hot air jet sphere (2) which is installed at a predetermined interval up and down, the hot air jet sphere (2) is discharged to the outside of the hot air jet sphere (2) through a plurality of injection holes formed on the injection surface of the hot air jet sphere (2) To pass the fabric through) In this way, the temperature difference according to the difference in the respective fan efficiency, as in the case where a plurality of fans are installed because only a single hot air supply fan (3) is installed in the drying chamber (1), not a plurality. By sending the hot air to each hot air jet sphere (2) evenly mixed without being generated it is possible to dry the fabric passing through the hot air jet sphere (2) more quickly and uniformly.

In addition, the hot air circulation structure according to the present invention has a constant vortex generation preventing plate 4 having a predetermined width between the outlet 32 of the hot air supply fan 3 and the hot air inlet of the hot air injection port 2 installed in the drying chamber. Due to the height, the hot air is sucked through the inlet 31 of the hot air supply fan 3 and discharged and supplied to the hot air jet port 2 inside the drying chamber 1 through the outlet 32 to cause vortices. It is possible to fundamentally prevent the circulation of hot air flowing through the drying chamber (1), as well as to maintain a constant circulation rate of hot air can increase the drying efficiency for the fabric.

As described above, although the present invention has been described with reference to the above embodiments, it is not necessarily limited thereto, and various modifications can be made without departing from the scope and spirit of the present invention.

As can be clearly seen from the above description, according to the drying chamber hot air circulation structure of the fiber heat treatment apparatus of the present invention, a single hot air supply fan is provided inside the drying chamber of the fiber heat processor to allow the fabric woven from the weaving machine to be dried by hot air while passing through the interior of the drying chamber. To the side of the outlet of this hot air supply fan, It is possible to prevent the generation of vortices and temperature deviation of hot air continuously circulated and supplied to the hot air jet by improving circulation of hot air circulating inside the drying room to increase the drying efficiency of the fabric, thereby obtaining better quality fabrics. To provide useful effects.
