The fall prevention member 47 prevents the product 5 from tipping over, and is formed so as to be erected on either the left end or the right end of the mounting table 46 in the width direction B, as shown in FIGS. 11, 13, and 14. , Like the mounting table 46, it is formed long in the longitudinal direction L. The fall prevention member 47 is formed lower than the supply wall 21. On the plate surface of the fall prevention member 47, upper partition dropping holes 47a for flowing hot water W in the direction of the upper bottom 11 are formed at predetermined intervals in the longitudinal direction L.

By the way, as shown in FIG. 1, the tray 2 having the above configuration can be stacked and accommodated in a plurality of stages in the vertical direction in the tank main body 6. In one tray 2, the accommodating area includes an upper bottom 11, a partition member 45, a width inner peripheral wall 16, and a side plate 31, and when the products 5 are arranged vertically and horizontally on the mounting table 46 of the partition member 45, the fall prevention member 47 is provided. Prevents the product 5 from tipping over. Further, as shown in FIG. 3, by inserting a hole 37a of the lower end peripheral wall 37 of the outlet member 32 in the upper tray 2 into the pin 43 laid on the longitudinal support member 33 (support portion 42), a plurality of stages are provided. As a tray group, the trays are stacked in a plurality of stages in the processing tank 3. As a result, the tray 2 can be prevented from slipping in the horizontal direction.

At this time, for example, the tip portion of the lower pin 43 is fitted into the lower end peripheral wall 37 of the outlet member 32 in the upper tray 2, and the upper outlet member 32 is fitted to the support portion 42 of the lower longitudinal support member 33. The lower end peripheral wall 37 is supported. Further, as shown in FIG. 2, since the lower surface 19c of the lower width support plate member 19 in the upper stage is supported on the upper surface 19a of the lower width support plate member 19, the trays 2 are stacked in the vertical direction. You can definitely do it.

The trays stacked in the upper and lower stages are inserted through the opening of the tank body 6, and the opening of the tank body 6 is sealed with a lid. At this time, as shown in FIG. 1, the spray nozzle 4 installed in the piping system 7 is set to be located in the long hole 20 for supply of each tray 2 in the width direction B.

As shown in FIG. 2, when hot water Wa is supplied from the supply port 4a of each spray nozzle 4 in the width direction B arranged outside the tray 2, the hot water Wa is supplied from the width outer peripheral wall 15. It is supplied from the long hole 20 and collected in the sewage reservoir 13 from the hot water space 23. That is, the hot water Wa ejected from the supply port 4a of the spray nozzle 4 is surrounded by the lower bottom 12, the upper bottom 11, the width outer peripheral wall 15, the width inner peripheral wall 16 (supply wall 21), and the width horizontal wall 17. It reaches the hot water space 23 and collects in the lower bottom 12, the upper bottom 11, the width outer peripheral wall 15, and the sewage reservoir 13 surrounded by the side plate 31.

At this time, the hot water Wa hits the supply wall 21, and the hot water Wa hitting the supply wall 21 is hindered by the width horizontal wall 17 and the width outer peripheral wall 15, and the speed of the hot water Wa in the horizontal direction is suppressed. And is supplied to the hot water space 23.

Then, the hot water Wa to which the hot water Wa is supplied and supplied from the long hole 20 for supply hits the supply wall 21, and since the product 5 is arranged inside the supply wall 21, it is supplied from the spray nozzle 4. The hot water Wa does not directly hit the product 5. Since the hot water Wa from the spray nozzle 4 hits the supply wall 21, even if the hot water Wa is supplied from both spray nozzles 4 in the width direction B, the hot water W collected in the sewage reservoir 13 is rippling. Can be suppressed.

Further, when the hot water W is accumulated in the sewage reservoir 13 from the hot water space 23, the momentum of the hot water W supplied to the sewage reservoir 13 is decelerated on the upper surface of the lower bottom 12, deceleration on both sides in the width direction B. The member 24 is installed. The deceleration member 24 is a block-shaped member having a rectangular cross section extended in the longitudinal direction L, is in the vicinity of the inner peripheral wall 16 of the width, and is fixed directly below the deceleration member 24. Since it is between the two, the hot water W is supplied (flowed) from above the deceleration member 24 to the inside of the sewage reservoir 13.

Therefore, the hot water Wa supplied to the hot water space 23 collects in the sewage reservoir 13 so as to ride on the deceleration member 24 by arranging the deceleration member 24. In other words, the hot water Wa passes over the deceleration member 24 from the outer end of the lower bottom 12 on which the deceleration member 24 is installed, and reaches the lower bottom 12 inside the deceleration member 24. The region of the outer end of the lower bottom 12 on which the deceleration member 24 is installed is referred to as a receiving portion region 12A, and the region extending to the inner lower bottom 12 of the deceleration member 24 is referred to as a dropping region 12B.

In this way, the hot water Wa rides on the speed reducing members 24 on both sides in the width direction B, whereby the momentum of the hot water Wa is decelerated, so that the ripple of the hot water W in the sewage reservoir 13 can be suppressed.

The heat treatment device 1 is provided with a control device (not shown) for controlling the hot water Wa from the spray nozzle 4 so that the depth of the hot water Wa collected in the sewage reservoir 13 becomes a desired amount. ing.

By the way, the flow of the hot water W supplied to the sewage reservoir 13 in the treatment tank 3 (tank main body 6) will be described as follows.

(1) The hot water W supplied to the sewage reservoir 13 is dropped from the lower dropping hole 12a of the lower bottom 12 onto the product 5 arranged in the lower tray main body 8 to heat the product 5.
(2) A lower partition dropping hole 46a is formed on the plate surface of the mounting table 46 of the partition member 45 on which the product 5 is arranged, and the hot water W flows from the lower partition dropping hole 46a toward the upper bottom 11. Shed.
(3) Since the water reservoir 49 surrounded by the upper bottom 11, the width inner peripheral wall 16, and the swash plate 48 is arranged on the upper side of the upper bottom 11, the product 5 is heated and the hot water W is generated. It collects in the water reservoir 49.
(4) The hot water W collected in the upper water reservoir 49 is dropped onto the sewage reservoir 13 through the upper dropping hole 11a formed in the upper bottom 11.
(5) The hot water W dropped on the sewage reservoir 13 passes through the lower dropping hole 12a formed in the lower bottom 12 and further drops on the lower product 5 to heat the product 5, and the hot water W is generated. It collects in the water reservoir 49.
Such a flow of hot water W is performed in the upper and lower tray main bodies 8.

By the way, since the water passage elongated hole 22 is formed in the width inner peripheral wall 16, the hot water W that drops into the water reservoir portion 49 and reaches the water passage elongated hole 22 is a hot water space from the water passage elongated hole 22. It is supplied to 23 and is collected in the sewage reservoir 13 so as to ride on the deceleration member 24 again.

As described above, the hot water W dripping into the water reservoir portion 49 and reaching the water flow slot 22 is supplied from the water flow slot 22 to the hot water space 23, but the side plate 31 has an outlet hole 34. It is formed. Therefore, the hot water W dropped on the water reservoir 49 flows out from the outlet hole 34 through the upper partition dropping hole 47a formed in the fall prevention member 47, and reaches the inside of the outlet member 32. Since the outlet member 32 is formed with an open hole 39 in which both ends of the L in the longitudinal direction are open, the hot water W flows out of the open hole 39 to the outside of the tray 2 and is supplied to the piping system 7 again.

As described above, since the hot water Wa from the spray nozzle 4 hits the supply wall 21, it is possible to suppress the ripple of the hot water W accumulated in the sewage reservoir 13, and the hot water W is a deceleration member on both sides in the width direction B. When the hot water W reaches the sewage reservoir 13 by riding on the 24, the momentum of the hot water W is decelerated, so that the hot water W of the sewage reservoir 13 does not undulate further. In this way, since the hot water W can be dropped from the lower dropping hole 12a in a state where the sewage reservoir 13 is suppressed from waving with respect to the hot water W, a plurality of products 5 are provided in the upper water reservoir 49 of the lower tray 2. Even if there is, the temperature difference with respect to these products 5 is extremely small (the temperature distribution is even), and therefore heating is smoothly performed.

Further, in the present embodiment, as shown in FIG. 3, it is possible to heat two types of products 5 having different contents. In the clean water reservoir 49, the product 5 having a small content can be stored only to a depth that does not float with respect to the hot water W (or cooling water). Therefore, if the amount of the hot water W to be dropped is uneven in a plan view, the product 5 that is not sufficiently heated (or cooled) is produced. Therefore, in the present embodiment, the depth of the hot water W in the water reservoir 49 is made uniform, and the amount of the hot water W dropped at each position in the plane direction (arranged vertically and horizontally) is the same. , All products 5 can be sufficiently heated.

As described above, when the hot water Wa supplied from the spray nozzle 4 is supplied from the supply slot 20 to the hot water space 23, the hot water Wa hits the supply wall 21 and the product 5 is the supply wall 21. Since it is arranged inside, the hot water Wa supplied from the spray nozzle 4 does not directly hit the product 5. Then, the hot water W dripping into the water reservoir portion 49 and reaching the water flow slot 22 is supplied from the water flow slot 22 to the hot water space 23, but the water flow length is relative to the supply slot 20. Since the hole 22 is formed in the lower portion, the hot water Wa from the spray nozzle 4 can easily enter the hot water space 23, and the hot water W can be supplied to the hot water space 23 from the water passage elongated hole 22. Therefore, the circulation of hot water W becomes smooth.

Further, in the tray body 8, the bottom plate 9 is a sewage reservoir 13 having a double bottom including a lower bottom 12 and an upper bottom 11. It is preferable that the sewage reservoir 13 needs to store a certain amount of hot water W, but the lower bottom 12 and the upper bottom 11 are formed separately, and the sewage reservoir 13 has a double bottom composed of the lower bottom 12 and the upper bottom 11. By doing so, the distance between the lower bottom 12 and the upper bottom 11 is shortened in the vertical direction, and a predetermined liquid depth (water depth) can be obtained. Therefore, the sewage reservoir 13 can be obtained without reducing the loading capacity of the product 5.

The present invention can be modified in various ways without departing from the spirit of the present invention. In addition, the specific configuration of each part is not limited to the above embodiment. In the above embodiment, the supply wall, that is, the width inner peripheral wall 16, is erected in the direction perpendicular to the upper bottom 11. However, the supply wall may be an inclined plate formed so as to incline outward of the tray 2 toward the upper side. Further, the width inner peripheral wall 16 may have a "cubic" cross section in which an intermediate portion thereof is tilted outward of the tray 2, or may be a semicircular shape protruding to the outside of the tray 2.

Further, in the above embodiment, the case where the deceleration member 24 has a rectangular cross section in the longitudinal direction L arranged on the lower bottom 12 is mentioned. However, the deceleration member 24 does not have to be limited to this shape, and the velocity component in the direction of the hot water Wa supplied to the inner peripheral wall 16 of the width and flowing downward (specifically, the dropping region from the receiving portion region 12A). Any shape may be used as long as it has a shape that reduces the velocity component in the direction toward 12B). Therefore, the deceleration member 24 may be, for example, a circular cross section having a convex upper portion, or may be a plate-shaped member standing vertically from the lower bottom 12.

In the above embodiment, the deceleration member 24 is located in the vicinity of the width inner peripheral wall 16 and is fixedly arranged immediately below the speed reduction member 24, but the position thereof is not limited to the vicinity of the width inner peripheral wall 16 and the deceleration member 24 is It can also be arranged inside the lower bottom 12 (between the lower dropping holes 12a). In the above embodiment, the deceleration member 24 is formed separately from the lower bottom 12, but may be integrally formed. Further, in the above embodiment, the deceleration member 24 is arranged and separated at a position corresponding to the water flow slot 22, but the deceleration member 24 is arranged so as to extend in the longitudinal direction L of the lower bottom 12. You can also.

Further, in the above embodiment, the spray nozzle 4 is used as the liquid supply unit, but the present invention is not limited to the spray nozzle 4, and any spray nozzle 4 may be provided. Further, the liquid supply unit does not have to be a spray.

In the above embodiment, the play nozzle 4 is on the outside of the tray 2, and the supply port 4a is provided in parallel with the long hole 20 for supply so as to correspond to the long hole 20 for supply. However, for example, if the supply directions of the hot water Wa (or cooling water) from the supply port 4a are parallel to each other, the supply port 4a can be changed in the vertical direction with respect to the long hole 20 for supply. ..

In the above embodiment, the example in which the spray nozzles 4 are arranged from both sides of the tray main body 8 is shown, but the spray nozzles 4 may be arranged only on one side of the spray nozzles 4.

In the above embodiment, hot water Wa is used as the medium, but cooling water may be used in some cases.
