Please refer to Figure 1A and Figure 1B. FIG. 1A is a schematic perspective view of a drying system 100 according to a first embodiment of the present invention. FIG. 1B is a top plan view of the drying system 100 of FIG. 1A. The drying system 100 includes a plurality of cavities 102a-102f and a guiding device 106. In particular, although six cavities 102a-102f are illustrated in FIGS. 1A and 1B, the present invention is not limited thereto, and the user may set the cavity according to the required process conditions, for example, less. Any or more than six cavities fall within the scope of the invention. The plurality of cavities 102a-102f each have an inlet and an outlet, and are sequentially arranged to form a channel 104. For example, the cavity 102a has an inlet I1 and an outlet O1, and is sequentially arranged with the cavities 102b-102f to form a channel 104.

The guiding device 106 is disposed in the cavity 102a-102f for guiding the cloth 108 to enter from the inlet I1 of the first one of the cavities 102a-102f (ie, the cavity 102a), and guiding the cloth 108 to the channel The 104 travels in the first direction D1. For example, the guiding device 106 can include a needle plate and a roller, and the cloth 108 can be secured through the needle plate and the cloth 108 can be fed into the channel 104 in conjunction with the roller.

2A and 2B are respectively side views showing different embodiments of the cavity 102f provided with the guide 114 in FIG. 1A. 2A and 2B, there are illustrated cavities 102f in cavities 102a-102f, wherein the cavities 102f are, for example, the last of the plurality of cavities 102a-102f and have an inlet I6 and an outlet O6.

Please first see FIG. 1A and FIG. 2A simultaneously. The drying system 100 includes a nozzle 110, at least one guide plate 114 and a heat exchanger 118. Nozzle 110 is disposed on inner wall 112 of cavity 102f to provide airflow 116 into passage 104, for example, nozzle 110 can provide airflow 116 into passage 104 by injection. In addition, the gas stream 116 can be heated to a high temperature gas stream through the heat exchanger 118. For example, the initial temperature of the gas stream 116 provided by the nozzle 110 can be increased by the heat exchanger 118 to between 100 ° C and 200 ° C. Through the high-temperature airflow provided by the nozzle 110, hot air may be stored in each of the cavities 102a-102f, so that the cavities 102a-102f can supply thermal energy to the cloth 108 therein to heat the cloth 108 to achieve the drying cloth. The effect of the material 108. In addition, although the number of nozzles 110 is illustrated as a plurality in FIG. 2A, in some embodiments, the number of nozzles 110 in each cavity may be one or any other number.

The guide plate 114 is disposed at least in the inner wall 112 in the cavity 102f. In other words, the guide plate 114 may be disposed in the other cavities 102a-102e in addition to the cavity 102f of the last node. For example, a guide plate 114 can be disposed in the cavities 102d-102f. That is, the guide plates 114 may be disposed in the last three sections of the cavities 102d-102f such that the hot air in the drying system 100 is guided by the guide plates 114 to flow back into the cavity of the front section. Since the cavities 102d-102f provide thermal energy to the cloth 108 through the hot gas and heat the cloth 108, the hot gas is returned to the front. The lumens of the segments (e.g., the cavities 102a-102c) can increase the efficiency of utilization of the thermal energy by the drying system 100. However, it should be understood that the number of the cavities 102d-102f provided with the guides 114 is merely illustrative, and is not intended to limit the present invention. Those skilled in the art to which the present invention pertains may, as needed, The guide plate 114 is provided by elastically selecting a cavity. For example, in other embodiments, when the drying system includes m cavities, the guide plates can be selectively disposed in the first to nth cavities to guide the hot gas to the cavity of the front section. In the body, thereby improving the utilization efficiency of the drying system 100 for thermal energy, wherein m and n are positive integers, and m>n.

The guide plate 114 extends from the inner wall 112 of the cavity 102f toward the inlet I6 of the cavity 102f, wherein the extending direction of the guide plate 114 is the second direction D2, and the second direction D2 and the inner wall 112 of the cavity 102f have the same An angle θ1. In other words, the arrangement direction of the guide plate 114 is inclined to the inner wall 112 of the cavity 102f, wherein the first included angle θ1 may be 15 degrees to 45 degrees.

Further, the direction in which the nozzle 110 provides the airflow 116 is the third direction D3, wherein the third direction D3 is orthogonal to the first direction D1. Since the arrangement direction of the guide plate 114 is inclined to the inner wall 112 of the cavity 102f, the second angle D2 and the third direction D3 have a second included angle θ2, and the second included angle θ2 may be 45 degrees to 75 degrees. The first angle θ1 and the second angle θ2 may be mutually complementary angles. For example, when the first angle θ1 is designed to be 30 degrees, the second angle θ2 is 60 degrees.

When the guide 114 and the nozzle 110 are disposed in the manner described above, the direction of travel of the airflow 116 provided from the nozzle 110 is guided by the guide 114 as indicated by the direction of the arrow on the depicted airflow 116. As described above, since the cavity 102f is the last of the plurality of cavities 102a-102f, the airflow 116 guided by the guide plate 114 travels along the channel 104 toward the cavity of the front segment (i.e., the cavity 102e, etc.). To be effective The airflow 116 provided by the nozzle 110 is utilized.

Furthermore, the temperature of the cloth 108 in the different cavities 102a-102f may vary, for example, the temperature from the first cavity 102a to the last cavity 102f may increase. In more detail, when the cloth 108 is moved from the inlet I1 of the drying system 100 to the outlet O6 by the guiding device 106, the heat energy provided by each of the cavities 102a-102f remains on the cloth 108 to make the cloth. The temperature of 108 gradually increases. As the temperature of the cloth 108 increases, the thermal energy provided by the drying system 100 to the cloth 108 will be greater than the thermal energy required to dry the cloth 108, which may result in a waste of heat. Therefore, by the guiding of the guide plate 114, the hot air in the cavity provided with the guide plate 114 can be moved toward the front joint cavity, so that the thermal energy can be guided from the position where the temperature of the cloth 108 is higher to the temperature of the cloth 108 is lower. The position, in turn, improves the utilization efficiency of the drying system 100 for thermal energy.

Taking the cavities 102e and 102f as an example, when the guide plate 114 is disposed in the cavity 102f, the airflow in the cavity 102f and the thermal energy remaining on the cloth 108 can be guided into the front cavity 102e to increase the cloth. The drying efficiency in the cavity 102e is such that excess heat energy can be effectively utilized, thereby further improving the drying efficiency of the drying system 100.

Furthermore, by adjusting the first angle θ1 and the second angle θ2, the relative positional relationship between the guide 114 and the nozzle 110 can be further adjusted. For example, when the guide 114 is adjacent to the nozzle 110 and tilted to a certain extent, one end of the guide 114 relative to the inner wall 112 of the cavity 102f can be located between the nozzle 110 and the cloth 108 such that the airflow 116 provided by the nozzle 110 It can be in contact with the guide plate 114, thereby increasing the guiding effect of the guide plate 114 on the airflow 116. The arrangement of the guides 114 will be further described below.

In this embodiment, the guide plate 114 includes at least one first guide plate 114a and at least one second guide plate 114b, and the first guide plate 114a and the second guide plate 114b are respectively disposed on the opposite side of the cloth 108 in the first direction D1. On both sides. Further, the configuration of the first guide 114a and the second guide 114b is symmetrical to the cloth 108. In this configuration, the airflow 116 provided by the nozzle 110 is guided into the front knuckle via the guidance of the first guide 114a and the second guide 114b.

In addition, the length of the guide 114 and the distance between the guide 114 and the cloth 108 can be further selected to increase the guiding effect of the guide 114 on the airflow 116. For example, the ratio of the minimum vertical distance L1 of the guide plate 114 to the cloth material 108 and the length L2 of the guide plate 114 in the second direction D2 is, for example, 1 to 3, and the length of the guide plate 114 in the second direction D2 is adjacent to The ratio of the horizontal distance L3 between the guide plates 114 is, for example, 2 to 8. However, it should be understood that the arrangement and size ratio of the above-mentioned guides 114 are merely exemplary, and are not intended to limit the present invention. Those skilled in the art to which the present invention pertains can flexibly select guides according to actual needs. The configuration of the board 114 is proportional to the size. For example, those having ordinary skill in the art to which the present invention pertains can adjust the arrangement of the guides in accordance with the temperature environment of the cavity 102f.

Please refer to FIG. 2B. The arrangement of the guide plates 114 can also be as shown by the guide plate 114 of FIG. 2B. The first guide plate 114a and the second guide plate 114b are located on both sides of the cloth material 108, and the first guide plate 114a and the second guide plate 114b are arranged alternately. In this configuration, the hot gas remaining in the cavity 102f can be increased to adjust and distribute the ratio of the hot gas remaining in the cavity 102f to the hot gas being directed to the front cavity.

In summary, the drying system of the present invention comprises a cavity, a nozzle and Guides. The nozzle is disposed on the inner wall of the chamber and provides a high temperature air flow to allow hot air to be present in the chamber.
