[Detailed explanation of the idea]

INDUSTRIAL APPLICATION FIELD The present invention relates to an airtight water sealing device for a cooler. BACKGROUND ART As shown in FIG. 5, for example, a conventional circular cooler 11 has a circular moving frame 13 connected by a connecting beam 12, and a material to be cooled 14 which forms the bottom part of the moving frame 13 and which is loaded with the moving frame 13. a trough 17 that is guided by a guide rail 15 and moves on a bottom rail 16;
It has a fixed air chamber 18 that supplies cooling air from below the trough 17 and a fixed hood 19 that collects the cooling air after cooling the material 14 above the moving frame 13. Airtight water seal devices 20 are provided on both sides along the trough movement direction between the upper end of the fixed air chamber 18 and between the upper end of the movable frame 13 and the lower end of the fixed hood 19. A lower water seal device 20A provided between the upper end of the fixed air chamber 18 is suspended from a water box 21A provided at the upper end of the fixed air chamber 18 and the lower part of the trough 17, and its tip is submerged in the water box 21A in the direction of trough movement. An upper water seal device 2 is constructed of a seal plate 22A that is fitted in a relatively movable manner, and is provided at the upper end of the movable frame 13 and the lower end of the fixed hood 19.
0B is a water box 2 provided at the lower end of the fixed hood 19
1B, and a seal plate 22B that is folded back in a U-shape from the upper end of the moving frame 13, and is fitted into the water box 21B so that its tip is submerged in water so as to be relatively movable in the trough movement direction. . Also, a water box 21 is placed on the top of each seal plate 22A, 22B.
Cover materials 23A and 23B are provided to cover A and 21B. Problems to be Solved by the Invention According to the above structure, despite the cover material 23, dust and dust scattered in the cooling air or from the cooled material 14 enters the water box 21 and settles at the bottom of the water box 21. In order to solidify the dust, the operation of the cooler 11 is stopped periodically or depending on the amount of dust accumulated.
The inside of the water box 22 had to be cleaned to remove accumulated dust. The present invention solves the above-mentioned problems, and aims to provide a cooler water seal device that facilitates maintenance of the water seal device. Means for Solving the Problems In order to solve the above problems, the present invention includes a fixed air chamber that supplies cooling air from below;
An airtight airtight structure is provided between the troughs loaded with materials to be cooled and moved above the fixed air chamber, and between the movable frames and the fixed hoods for collecting cooling air, which are arranged on both sides along the trough movement direction. In a water sealing device for a cooler, a plurality of funnels are provided at the bottom of a water box into which a seal plate is fitted so that its tip is submerged in water so that it can be moved relative to the trough along the direction of movement of the trough, and a drain pipe is connected to the bottom end of the funnel. This is a connected configuration. Operation With the above configuration, by simply supplying and draining water for the water box continuously or appropriately, the dust that has entered the water box and settled therein can be reliably discharged and removed from the lower end of the funnel as the water is drained, before it solidifies. Embodiment An embodiment of the present invention will be described based on the drawings.
FIG. 1 is a side view showing an embodiment of the present invention, FIG. 2 is a view taken along the - arrow in FIG. 1, and FIGS. 3 and 4 are schematic illustrations thereof. In this embodiment, the same parts as in the conventional example are indicated by the same reference numerals, and the explanation thereof will be omitted. 1 to 4, 31 is a water box of the lower water sealing device 30 provided along both upper ends of the fixed side air chamber 18, and a plurality of funnels 34 are provided at predetermined intervals at the lower end of the water box 31. provided,
A drain pipe 35 is provided at the lower end of each funnel 34. Numeral 36 denotes water supply pipes provided at appropriate intervals, which open at the top of the water box 31 to supply water. An electric drain valve 37 and an electric water supply valve 38 are interposed in the drain pipe 35 and the water supply pipe 36. The operation of supplying and discharging water into the water box 30 is performed by opening and closing each drain valve 35 and water supply valve 36 as appropriate.
5 and 36 should be operated more frequently than other parts. Furthermore, as shown in FIG. 3, a level meter 39 for detecting the water level in the water box 31 is provided, and the drain valve 37 and the water supply valve 38 are continuously opened and closed based on the detection signal, thereby enabling automation and saving labor. Further, the drain valve 35 and the water supply valve 38 can be operated intermittently using a timer 40. Next, the operation of this lower water seal device 30 will be explained. When the drain valve 37 and the water supply valve 38 are opened to supply and drain water in the water box 31, the dust that has entered the water box 31 and settled at the bottom of the water box 31 is removed from the water box 3.
1 moves into the funnel 34, and the funnel 34
The water is reliably drained and removed from the drain pipe 35 at the lower end. For example, when the water sealing device 30 is automated and operated continuously, the relationship between the water level detected by the level meter 39 (detection at two points, High and Low) and the operation of the drain valve 37 and water supply valve 38 is shown in Table 1. It becomes like this.

[Table] In addition to continuous operation, intermittent operation using the timer 40 is also possible, and each operation begins with drain valve 3.
The process starts by opening 7. Although the lower water seal device 30 has been described above, the upper water seal device between the movable frame 13 and the fixed hood 19 has a similar configuration. Effects of the Invention As described above, according to the present invention, dust that has entered the water box can be reliably discharged and removed from the funnel together with the drainage, so maintenance of the water sealing device can be facilitated.
