  The cooling device of Patent Document 1 exhibits an excellent cooling capacity and can be cooled to a temperature range in which a worker touches the surface of the cast coarse material within a predetermined time. However, since water is used, a circulation pump and a heat exchanger unit are indispensable, and pipes and valves associated therewith are also required. Therefore, there is a problem that the structure of the entire cooling device is complicated.

  In addition, since the water in the equipment is contaminated with dust and sand adhering to the cast coarse material, etc., the water in the water tank must be replaced periodically, and maintenance work of the equipment such as cleaning of the pump unit etc. There is also a problem that it takes time and effort.

  Therefore, the present invention has been made in view of the above problems, and can cool high-temperature parts such as cast coarse materials without using water, and can collect dust and sand. An object of the present invention is to provide a cooling device for high-temperature parts that is excellent in maintenance cost.

  In order to solve the above problems, a cooling device for high-temperature components according to the present invention includes a carry-in unit that carries high-temperature components into the device, a cooling unit that blows and cools cooling air on the carried high-temperature components, and A blower for supplying cooling air to the cooling unit, a carry-out unit for carrying out the cooled high-temperature component out of the apparatus, and a high-temperature component contained in the cooling air blown to the high-temperature component in the cooling unit. And a dust collecting unit that collects dust and the like and discharges the cooling air after the collection.

  According to this, since the high-temperature parts such as the cast coarse material are cooled only by the cooling air without using water and the dust and sand are collected, the structure of the apparatus can be simplified. In addition, since it is only necessary to replace the consumables in the dust collecting section, a cooling device with excellent maintenance costs is realized.

  Here, it is preferable to include a door state detection unit that detects an open / close state of the carry-in unit and the carry-out unit.

  Moreover, it is preferable that the said ventilation part is provided with the frequency adjustment part which adjusts the air volume of the cooling air supplied to a cooling part by adjusting an electric motor frequency.

  Furthermore, it is more preferable that the frequency adjustment unit adjusts the motor frequency based on a detection result in the door state detection unit.

  According to this, since the air volume of the cooling air is adjusted according to the open / close state of the carry-in door and the carry-out door, it is possible to realize a cooling device excellent in consideration of the factory environment that does not scatter dust and sand. Become.

  As described above, according to the cooling device for high-temperature parts according to the present invention, cooling of high-temperature parts such as cast coarse materials with cooling air is performed without using water, and dust and sand are also collected. The entire apparatus can have a simplified structure, and a cooling apparatus with excellent maintenance costs can be realized.

It is a block diagram which shows the functional structure of the cooling device which concerns on embodiment of this invention. It is a perspective view which shows the structural example of a cooling device. It is a perspective view which shows the structural example of the conventional cooling device.

  Hereinafter, a cooling device for high-temperature parts according to the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing a functional configuration of a cooling device according to an embodiment of the present invention.

  The cooling device 1 is a device that cools a cast coarse material that is a high-temperature part, and includes a carry-in unit 10 that takes the cast coarse material into the device, a cooling unit 11 that cools the cast coarse material, and a cooled cast coarse material. And a carry-out unit 12 for discharging the outside. The cooling device 1 includes a blower unit 13 that supplies cooling air (cooling air) for cooling to the cooling unit 11, a door state detection unit 15 that detects the open / closed states of the carry-in unit 10 and the carry-out unit 12, And a dust collecting unit 16 that collects dust and sand from the cooling air used for cooling in the cooling unit 11.

  The carry-in part 10 is a door or the like for taking the cast coarse material into the apparatus. The open / closed state of the door of the carry-in unit 10 is always detected by a door state detection unit 15 described later.

  The cooling unit 11 is a space (cooling chamber) for cooling the cast coarse material taken into the apparatus. The cooling unit 11 also includes a transport unit that sequentially transfers the cast coarse material entering the apparatus from the carry-in unit 10 in the longitudinal direction. In the cooling unit 11, the cast coarse material is cooled by the cooling air supplied from the blower unit 13 while the cast coarse material is transferred by the transport unit. The cooling air used for cooling is sent to the dust collector 16 together with dust and sand adhering to the cast coarse material.

  The carry-out unit 12 is a door or the like for discharging the cooled cast coarse material to the outside of the apparatus. The open / closed state of the door of the carry-out unit 12 is always detected by a door state detection unit 15 to be described later, similarly to the carry-in unit 10.

  The air blowing unit 13 is a blower that generates cooling air to be supplied to the cooling unit 11. The air blowing unit 13 takes in fresh air in a facility such as a factory where the cooling device 1 is installed, and sends cooling air to the cooling unit 11. The air blowing unit 13 includes a frequency adjusting unit 14.

  The frequency adjusting unit 14 is a control device that controls the motor frequency of the blower. The frequency adjusting unit 14 adjusts the air volume of the cooling air supplied from the air blowing unit 13 to the cooling unit 11 by controlling the motor frequency based on the output of the door state detecting unit 15.

  The door state detection unit 15 is a processing unit that detects the open / closed state of the doors of the carry-in unit 10 and the carry-out unit 12 and outputs the detection result to the frequency adjustment unit 14 and is realized by a door open / close sensor or the like. When the door state detection unit 15 detects that the doors of the carry-in unit 10 and the carry-out unit 12 are open, the door state is output to the frequency adjustment unit 14, and the frequency adjustment unit 14 Reduce the air volume of the cooling air by reducing the motor frequency. Thereby, dust and sand can be prevented from scattering from both doors to the outside of the apparatus.

  The dust collection unit 16 is a dust collection filter that collects and collects dust and sand from the cooling air used for cooling in the cooling unit 11, and an exhaust fan that discharges the cooling air after collecting the dust and sand to the outside of the apparatus. It is realized by.

  FIG. 2 is a perspective view illustrating a configuration example of the cooling device 1.

  The cooling device 1 includes a carry-in door 20 corresponding to the carry-in unit 10, a cooling chamber 21 corresponding to the cooling unit 11, a carry-out door 22 corresponding to the carry-out unit 12, a blower 24 and a blower port 23 corresponding to the blower unit 13. And. The cast coarse material 2 taken into the apparatus from the carry-in door 20 is cooled by the cooling air sent from the blower 24 and blown out from the blower opening 23 while being sequentially transferred in the direction of the carry-out door 22 in the cooling chamber 21. It is discharged from the carry-out door 22. The cooling air generated by the blower 24 is air, for example, air at about room temperature in a facility such as a factory. Therefore, it is not necessary to use water, and not only a circulation pump and a heat exchanger unit, but also piping and valves are not required, so that the structure of the entire cooling device can be simplified.

  The cooling air used for cooling in the cooling chamber 21 is sent to the dust collection unit 27 through the opening 25 that connects the cooling chamber 21 and the dust collection unit 27. The dust collection unit 27 corresponds to the dust collection unit 16 and includes a dust collection filter 26 and an exhaust blower 28. The dust collection filter 26 collects and collects the dust and sand, since the dust and sand adhered to the coarse casting material 2 are sent into the dust collection unit 27 by the cooling air used for cooling. The cleaned cooling air is sucked by the exhaust blower 28 and diffused out of the apparatus. Here, the dust and sand accumulated in the dust collection unit 27 need only be cleaned by the dust collection unit 27 or replacement of the dust collection filter 26, which is a consumable item. Therefore, compared to a conventional cooling device using water, Complicated maintenance work such as cleaning of the pump unit or the like is not necessary, which is advantageous in terms of maintenance costs.

  The blower 24 also has a function of the frequency adjusting unit 14, is normally operated at a predetermined frequency (for example, 60 Hz), and detects the door state when the carry-in door 20 and the carry-out door 22 are open. A door opening / closing sensor (not shown) corresponding to the section 15 detects this, and automatically reduces the frequency (for example, 30 Hz) to reduce the amount of air blown from the air outlet 23. Thereby, even if the dust and sand adhering to the casting coarse material 2 remain in the cooling chamber 21, it is possible to prevent the dust and sand from scattering from the carry-in door 20 and the carry-out door 22 to the outside of the apparatus. . If the frequency reduction rate is too low, the rate of airflow reduction will also be low, and it will be difficult to suppress dust and sand scattering. On the other hand, if the frequency reduction rate is 100%, that is, even if the blower 24 is stopped, if the stop time is short, the suction force of the exhaust blower 28 of the dust collection unit 27 suppresses the decrease in cooling capacity, which is a problem. There is nothing to do.

  The cooling device 1 having such a configuration can cool high-temperature parts such as a cast coarse material without using water, and can also collect dust and sand. Moreover, since water is not used, the structure of the whole cooling device can be simplified, and the cooling device excellent in maintenance cost is implement | achieved.

  As mentioned above, although the high temperature component cooling device according to the present invention has been described based on the embodiments, the present invention is not limited to this, and the scope of the present invention can be achieved and does not depart from the gist of the invention. Various design changes are possible within the scope of the present invention, and they are all included within the scope of the present invention.

  For example, in the above-described embodiment, the description has been made as a transport-type cooling device that sequentially cools the cast coarse material by moving it in the longitudinal direction, but the cast coarse material for one shot of the casting cycle (every casting) is the cooling chamber. You may apply to the batch-type cooling device which adapted the cooling cycle and the casting cycle which carry in, cool, and carry out.

  The cooling device for high-temperature parts according to the present invention is useful as a cooling device for rapidly cooling high-temperature parts such as a cast coarse material immediately after casting.
