Hereinafter, the operation of the eco-friendly three-dimensional hot air drying apparatus for improving the efficiency of hot air energy in the drying process of the container washing apparatus of the present invention will be described in detail with reference to the accompanying drawings.

First, in order to perform drying in the drying apparatus 1 of the present invention, the container 40 is turned upside down on the conveyor 30 to enter the main body 10, and the label is called in the apparatus 11, The rinsing in the rinsing device 14 and the dewatering in the dewatering device 15 are progressed sequentially in the removal device 12 and then in the drying chamber 20, The hot air drying of the container 40 is performed.

Thus, as for the operation of the drying apparatus 1,

First, as shown in FIG. 11, the upper drying by the upper drying means 100 is carried out,

Referring to FIGS. 2 and 3, when the front rotation shaft 121 is rotated forward by the operation of the upper drive motor 122, the horizontal guide bar 124 is positioned at the upper position And the upper air knife 113 supported by the horizontal guide roller 114 on the upper portion of the horizontal guide bar 124 is lifted upward along with the folding of the corrugated pipe 112.

In order to dry the upper portion of the container 40, when the upper driving motor 122 is operated in the opposite direction, a rotational force is applied to the front rotating shaft 121, and the front rotating bar 123 rotates rearward At this time, the rear rotation bar 123 'and the rear rotation shaft 121' connected by the horizontal guide bar 124 are also imparted with the same rotational force.

At this time, the horizontal guide bar 124 maintains the same horizontal state at all times, and the height of the horizontal guide bar 124 changes due to the nature of the movement along the arc.

That is, when the height of the horizontal guide bar 124 is adjusted, the upper air knife 113, which is supported by the horizontal guide roller 114 and is supported above the horizontal guide bar 124, 112), the height thereof is naturally adjusted.

As described above, in the process of adjusting the height of the upper air knife 113, a frictional force with the horizontal guide bars 124 and 124 acts on the guide rails 114, To be overcome.

Since the vertical guide roller 115 is guided by interfering with the vertical guide bar 125, the upper air knife 113 which is operated to ascend and descend is guided by the vertical guide roller 115, .

On the other hand, the upper air knife 113, which moves up and down as described above, discharges high-pressure hot air by the upper turbo fan 111, and the upper air knife 113, which moves by the hot air, Moisture can be easily removed by a high-pressure hot air at a position closest to the top (bottom surface) of the city container 40.

Further, as shown in Fig. 12, the lower drying by the lower drying means 200,

4 to 6, primary drying by the first lower air hot air unit 210 formed at the rear side and secondary drying by the second lower air hot air unit 220 formed at the front side are performed.

That is, when the container 40 enters, the first hot airflow is first performed by the first lower hot air unit 210.

That is, the hot air can be dried in the lower portion (inside) of the container 40 by the first lower air knife 212. When the hot air is blown by the first lower turbo fan 211, The inclined air curtain is formed in the width direction by the backward inclined ejection opening 213 of the container 40, and the primary hot air drying in the container 40 is performed.

Thereafter, the second hot air unit 220 continuously performs the secondary hot air drying.

That is, the second lower air knife 222 is capable of drying hot air in the lower portion (inside) of the container 40. When the second lower air knife 222 applies high-pressure hot air by the second lower turbo fan 221, A vertical hot air drying is performed inside the container 40 in which the vertical and inclined air curtains are formed in the longitudinal direction by the vertical discharge ports 223 and 223 'and the inclined discharge ports 224 and 224' Moisture can be easily removed.

At this time, the second lower turbo fan 221 is formed in the longitudinal direction of the drying chamber 20, and hot air is supplied to the inside of the container 40 for a longer time than the first order, so that it is possible to completely remove moisture .

Further, as shown in Fig. 13, side drying by the side drying means 300,

Referring to FIGS. 7 and 8, when the front rotation shaft 321 is rotated forward by the operation of the side drive motor 322, the horizontal guide bar 324 is positioned at the upper position The side air heating unit 310 is configured such that the branch pipes 313 and 313 'and the rotary pipes 317 and 317' are connected to the corrugated pipe 312 from above the horizontal guide bar 324 by the horizontal guide roller 315, And the side air knives 318 and 318 'are inclined forward and are raised. At the same time, the air knife 318' is guided by the second horizontal guide roller 319 formed at the end thereof, Thereby being in a state of being seated and supported on the bar 326.

In order to dry the side surface of the container 40, when the side driving motor 322 is operated in the opposite direction, a rotational force is applied to the front rotating shaft 321 and at the same time, the front rotating bar 323 rotates rearward At this time, the rear rotation bar 323 'and the rear rotation shaft 321' connected by the horizontal guide bar 324 are also given the same rotational force.

Meanwhile, the horizontal guide bar 324 also moves in the arc during the rotation of the front and rear rotation bars 323 and 323 'as described above. At this time, the horizontal guide bar 324 is always in the same horizontal state And the height thereof is changed in accordance with the characteristic of moving along the arc only.

That is, the branch pipes 313, 313 'and 313', which are supported by the first horizontal guide roller 315 on the horizontal guide bar 324 in accordance with the arc motion of the horizontal guide bar 324, 317) 317 'Also, the height of the corrugated tube 312 is adjusted naturally as the corrugated tube 312 is expanded and folded.

Meanwhile, the frictional force with the horizontal guide bar 324 is applied during the height adjustment of the side air knives 318 and 318 ', which is overcome by the rolling of the first horizontal guide roller 315.

The branch pipes 313 and 313 'and the rotary pipes 317 and 317' which are operated to move up and down are guided by the vertical guide rollers 314 interfering with the vertical guide bar 325, So that only the upper and lower vertical lifts can be performed smoothly.

The angles of the side air knives 318 and 318 'raised and lowered in the upward and downward directions of the branch pipes 313 and 313' and the rotary pipes 317 and 317 ' This is possible by rotating the rotary pipes 317 and 317 'connected to the branch pipes 313 and 313' by the swing hinge 316.

That is, when the branch pipes 313 and 313 'and the rotary pipes 317 and 317' are lowered, the ends of the side air knives 318 and 318 'are moved by the second horizontal guide roller 319 The downward movement of the air pipes 317 and 317 'causes the front side of the side air knives 318 and 318' to descend while the downward movement of the air pipes 317 and 317 ' The ends of the side air knives 318 and 318 'are adjusted by the air knife guide bar 326 by the rolling of the second horizontal guide roller 319, As shown in FIG.

Since the angle of the side air knives 318 and 318 'as described above is always equal to the height of the container 40, the high-pressure hot wind is discharged by the side turbo fan 311, 40 and the side air knives 318 'and 318' are gently sloped in the process of removing the air knife 318 ' It is possible to remove moisture more easily by increasing the transfer area.

On the other hand, the hot air used in the process of performing drying of the upper part of the container 40, lower drying and side drying is generated and circulated by the upper and lower hot air circulation means 400 and 400 ' ,

First, as shown in FIG. 9, the upper hot air circulation means 400 can apply hot air to the upper drying means 100 and the side drying means 300.

First, when generating the first hot air, the air can be heated and supplied by the operation of the heater 423 of the hot air adjusting unit 420.

That is, the air heated inside the circulating duct 410 is supplied to the upper turbo fan 111 and the side turbo fan 311, and is discharged into the drying chamber 20.

The air discharged into the drying chamber 20 is circulated through the circulating duct 410 so that the blower 411 formed in the circulating duct 410 and the upper turbo fan 111 and the side turbo fan 311 The air in the drying chamber 20 is sucked and discharged by the suction force, and foreign matter and moisture are filtered by the filter 421 of the hot air control unit 420, and the filtered air is discharged from the heat exchanger 422 The hot air that has been dried by the evaporation, compression, condensation, and expansion processes is generated and discharged into the suction and drying chamber 20 through the upper turbo fan 111 and the side turbo fan 311 again.

In addition, when hot air is supplied to the lower drying means 200, the lower hot air circulating means 400 'can be used.
