Description

  The present invention relates to a cooling device and a cooling method for efficiently cooling a high-temperature part such as a cast coarse material immediately after casting.

Products manufactured from cast aluminum materials such as aluminum need to be cooled as quickly as possible from the temperature immediately after casting to a temperature that can be handled by workers in order to maintain and improve the production efficiency. .
In this cooling method of the cast coarse material in a high temperature state, the cast coarse material is intermittently transferred in the longitudinal direction sequentially in a box container of an appropriate length after casting, and the cooling material is cooled in the box container. There is a configuration in which the cast coarse material is cooled during the transfer process by forcibly feeding air.
FIG. 4 shows an example of this configuration. The coarse casting material 41 is fed into the box-shaped container 42 from the upper right of the figure and is transferred so as to be discharged from the lower left of the figure. The box-shaped container 42 is supplied with compressed air from the blowing duct 43, and the cast coarse material 41 is cooled by the compressed air. The cooled air is discharged from the exhaust duct 44 outside the factory.

  Further, as shown in FIG. 6, a method in which a large number of shelves 51, 51,... In which a plurality of trays are stacked are placed, the cast coarse materials 52, 52,. Has also been implemented.

Further, there is a known technique related to air for cooling an object to be cooled such as a cast coarse material (for example, see Patent Document 1).
In Patent Document 1, water particles are attached to an object to be cooled contained in a cooling container by a spray mechanism using an ultrasonic humidifier, and dry cooling air is blown to the water particles to evaporate the water particles. A technique for rapidly cooling by latent heat of vaporization by repeating the above is disclosed.

Each of these devices is packaged in a case 12 and configured as a unit.

  1 and 2 show an example of the configuration of the cooling device 1 described above. The sealed container 2 is configured in a box shape (tunnel type) having a predetermined transport distance, and the inner space is configured as a cooling chamber 2a. Is done. One end of the sealed container 2 is configured as a delivery port 21, and the other end is configured as a delivery port 22. For example, cast raw materials 4, 4... Such as aluminum rough material after heat treatment are fed into the inlet 21, transferred through the cooling chamber 2 a by the transfer device 5, and sent out from the outlet 22.

The opening / closing doors 21a and 21b are opened only when the cast coarse material 4 is fed, and the opening / closing door 22b is opened only when the casting coarse material 4 is sent out. 2a is secured to prevent leakage of hot air to the outside.

Further, in the cooling chamber 2a, the temperature on the inlet 21 side into which the high-temperature cast raw material 4 is fed becomes particularly high, so that the open / close doors 21a and 21b of the inlet 21 have a double structure. As a result, high temperature hot air emitted from the cast coarse material 4 is prevented from leaking to the outside.
Specifically, when the cast coarse material 4 is fed, only the front door 21a is opened with the back side door 21b closed, and the cast coarse material 4 is opened. Is sent between the doors 21a and 21b, and when the door 21a is closed, the door 21b is opened. In this way, since the hot air in the cooling chamber 2a inside the open / close door 21b does not leak directly to the outside, the amount of heat leaking to the outside can be reduced.
In addition, the operation of the double doors 21a and 21b is performed by operating both the doors 21a and 21b by the link mechanism 23 and depressing the pedal 24, whereby the operator can open and close the doors. The opening / closing operation of 21a / 21b can be performed easily and reliably.

Further, in the water tank container 7, a gas-liquid contact filling 10 is provided at a substantially central portion in the vertical direction, and the gas-liquid contact filling 10 causes the air in the water tank container 7 and the spray device 8 to The contact area of the sprayed water is increased, and the water absorption rate for the air (in other words, the air absorption rate for water) is improved. Thereby, the cooling efficiency by the water of the cooling air is improved.
As for the gas-liquid contact packing 10, for example, a general configuration using a gas-liquid contact plate in which a metal flat plate and a metal net are joined, or a gas contact plate made of a polymer material is used. The specific configuration is not particularly limited.

In the water tank container 7, liquid water is always stored in the lower space 7 b, and the water is pumped up by the pump 11 and supplied to the spraying device 8. Spraying is performed in the upper space 7 a by the spraying device 8. In this manner, water for cooling the cooling air is circulated in the water tank container 7.
In addition, an air cooling unit for cooling the cooling air by water cooling is configured from the water tank container 7, the spray device 8, the pump 11, and the gas-liquid contact filler 10.
The water in the lower space 7b may be cooled by an external cooling device (not shown), and the temperature of water sprayed from the spraying device 8 may be always set to a predetermined temperature or lower.

Further, a demister 9 is interposed between the gas-liquid contact filler 10 and the cooling air supply device 6, and the air in the upper space 7 a is cooled after the mist is removed by the demister 9. The air is supplied to the commercial air supply device 6. Then, the air after the mist removal is supplied by the demister 9 as cooling air from the inlet 2b into the cooling chamber 2a.
In the demister 9, mist removal is performed so that the humidity of the cooling air blown into the cooling chamber 2a from the blow-in port 2b is less than 100%.
For the mist removal control by the demister 9, a humidity sensor is provided in the vicinity of the air inlet 2b, and the mist removal function unit of the demister 9 is controlled by the control device so that the detected value of the humidity sensor is less than 100%. The specific configuration is not particularly limited.

That is, the cast coarse material 4 immediately before being transferred to the vicinity of the blow-in port 2b and sent out from the cooling chamber 2a has been lowered in temperature from about 60 degrees to less than 100 degrees, and temporarily for cooling with a humidity of 100% or more. If air is blown in, the water in the cooling air will not evaporate and will form water droplets, and will gradually stay in the sealed container 2, which requires a mechanism for discharging the staying water, and the apparatus is complicated. It will become.
Further, when moisture adhering to the surface of the casting coarse material 4 is saturated and becomes water droplets, when there is a casting core, water stagnates into the casting core, and the casting core is altered and deteriorated, In the post-process core removal step, the casting core may partially remain in the cast coarse material 4 and become a defective product.
For these reasons, as described above, by setting the humidity of the cooling air to less than 100% by the demister 9, it becomes possible to avoid problems.

And in the above structure, the cooling air blown into the cooling chamber 2a from the blowing port 2b by the cooling air supply device 6 cools the cast coarse material 4, 4. It is discharged into the upper space 7a and cooled by spraying water by the spraying device 8 in the upper space 7a. Thereafter, the air is sucked by the cooling air supply device 6 through the demister 9 and then blown again from the blow port 2b.
Thus, since the cooling air in the cooling device 1 is circulated and used in the cooling chamber 2a and the upper space 7a without leaking to the outside, the working environment inside and outside the factory can be prevented from deteriorating.

When the outer door 21a is opened, the inner door 21b is closed. When the depression of the pedal 24 is released, the outer door 21a is closed and the inner door 21b is opened, and the conveying device 5 operates to cast each of the cast coarse materials 4, 4. Only the width of one coarse material 4 is transferred. At this time, the opening / closing door 22a of the delivery port 22 is opened so that the cooled cast coarse material 4 can be taken out.

In this way, by feeding the cooled cast coarse material 4 while feeding the high-temperature cast coarse material 4, the cast coarse materials 4, 4... Can be sequentially cooled. Further, in this case, since the work can be performed with one operation of the pedal 24, the worker can easily and reliably carry out the work.
