Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container drying apparatus, which is used for drying a container in a short time in a container yard for accumulating, storing, etc., containers for marine transportation.

[0002]

2. Description of the Related Art The inside of a container is contaminated due to the type of cargo, etc. Therefore, if the degree of contamination exceeds a certain standard, it is washed with water. Also, the inside may get wet due to causes other than washing with water. Conventionally, such a container has been opened in a container yard and naturally dried. However, when the container is naturally dried, it takes 2-3 days for the container to dry even if the weather is good. In addition, the number of dry days varies depending on the season and weather. Therefore, there are problems that the operating rate of the container is lowered and that the systematic operation management of the container cannot be performed. Further, since the rotation rate of the container is lowered, there is a problem that a large space is occupied to dry the container.

On the other hand, as a device for promoting the drying of the container, a self-propelled container cleaning device has been proposed in which the container is rinsed with a water cleaning device and air is blown to the cleaning surface to blow away the cleaning water. (See Japanese Utility Model Publication No. 63-193593). However,
In this device, since the cleaning water is simply blown off by air, the drying time is shortened to some extent, but a considerable natural drying time is required thereafter. Therefore, the drying time depends on the weather, etc., and when the weather is bad, the drying time becomes long and the time required for drying is not constant. Therefore, in this device, as in the conventional case, there are problems that the turnover ratio of the container is poor and the planned operation management of the container is hindered. Further, in such a combined use device of washing and drying, there is a problem that the washing is completed in a short time, whereas the drying takes time, and the operating rate of the washing device is deteriorated. Even when the drying is completed in a short time, the operation rate of each device is lowered. Moreover, the size of the entire apparatus increases and the cost thereof increases.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems in the prior art and to provide a container drying device which can dry a container in a constant short time and has a high operating rate. .

[0005]

In order to solve the above-mentioned problems, the present invention according to claim 1 provides a container drying device,
A nozzle portion having an opening facing the portion to be dried of the container, an air feeding means for feeding gas to the nozzle portion, a temperature raising means for raising the temperature of the gas, the nozzle portion, the air feeding means, and the rising portion. In addition to the above, the present invention according to claim 2 further comprises: a support for supporting the warming means; and a traveling means for traveling the support. 4. A seal member, which is attached to the support and covers a predetermined range behind the position of the nozzle portion in the direction, and which has an exhaust portion at the rear,
In addition to the above, the invention of claim 4 is characterized in that a forced exhaust means is provided in the exhaust portion.
In addition to the invention of claim 1, there is provided a traveling guide means provided with a contact portion which is attached to the support body and comes into contact with a side wall of the container, and the invention of claim 5 is characterized in that in addition to the invention of claim 1, The invention of claim 6 is characterized in that the invention comprises a swinging mechanism that changes the direction of the opening of the nozzle portion. In addition to the invention of claim 1, the temperature raising means has a combustion device for burning fuel. According to a seventh aspect of the present invention, there is provided a container drying device transporting vehicle, which is a container drying device, including a nozzle part having an opening facing a portion to be dried of the container, and an air supply for sending gas to the nozzle part. Means, a temperature raising means for raising the temperature of the gas, a support for supporting the nozzle portion, the air supply means and the temperature raising means, and a traveling means for traveling the support, The loading surface on which the And having a structure that is integrally formed with the height and the stacking surface of the comparable height of the floor of the container when it is, a moving means for moving the structure, a.

[0006]

According to the invention of claim 1, the nozzle is provided with an opening facing the portion to be dried of the container, and the gas feeding means for feeding the gas to the nozzle portion can apply the gas to the portion to be dried. it can. In an ordinary container, the floor surface is washed mainly because the floor surface is soiled. Therefore, the portion to be dried is usually the floor surface and the lower end portion of the wall surface that is wet with water as the floor surface is washed.
However, when the container drying device includes a container for cleaning the wall surface as a drying target, the wall surface is also the portion to be dried. In this case, the nozzle portion is provided for the floor surface and for the wall surface.

The temperature of the gas sent to the nozzle is raised by the temperature raising means. As a temperature raising means, a method of directly heating the outside air with an electric heater or the like, or a method of heating the outside air through a heat exchanger using a combustion gas as a heat source, or taking the outside air as combustion air to burn fuel There are some that use the combustion gas itself. When the temperature of the outside air is raised in this way,
The relative humidity decreases as the temperature increases. When such a heated gas (hereinafter referred to as “hot air”) hits a heated portion such as a floor surface, the temperature of that portion rises, and the moisture contained therein evaporates and dries. In this case, since the relative humidity of the hot air is low, the evaporation is continuously and vigorously carried out. As a result, the part exposed to hot air dries in a short time.

On the other hand, since the air supply means and the temperature raising means are supported by the support and can be moved by the running means, the nozzle portion can be moved in the running direction. As a result, all the portions to be dried in the traveling direction can be dried. With respect to the width direction of the container, for example, the nozzle portion can be formed to be movable in the width direction, or the entire area of the heated portion such as the floor surface can be dried by moving the support while shifting the width direction. it can. However, in the case of a sea container used for international transportation, the width is generally 8 ft specified by the ISO standard, and since it is almost constant, the nozzle part may have this width dimension. desirable.

According to the second aspect of the present invention, the seal member is provided to cover a predetermined range behind the nozzle portion in the heated portion. The hot air that hits the heated portion heats and heats the heated portion, but for that purpose, it takes time for heat exchange. Therefore, it is necessary to apply hot air to the surface of the heated portion to some extent continuously. On the other hand, even if the hot air hits the heated portion, the temperature does not drop so much at that moment, and the temperature is still sufficiently high. Therefore, when a seal member is provided as in the present invention, the hot air that once hits the heated portion is retained in the portion covered by the seal member, and the hot air flows over the heated portion by the traveling of the support and the continuous supply of the hot air. It will flow and you will hit it repeatedly. As a result, sufficient heat exchange is performed between the hot air and the heated portion, and the temperature of the hot air is sufficiently lowered. Therefore, hot air is effectively used and the energy required to dry the container is reduced. In this case, since the seal member is provided with the exhaust portion at the rear thereof, the gas sent by the air sending means is appropriately discharged, and the problem due to the increase in the internal pressure does not occur.

According to the third aspect of the present invention, since the forced exhaust means such as an exhaust fan is provided in the exhaust portion, the hot air can be discharged even if the flow path of the hot air inside the seal member is narrowed. Therefore, by narrowing the flow path, heat exchange between the hot air and the floor is promoted, and the temperature of the discharged hot air is lowered. As a result, the drying time is further shortened and the energy consumption for drying is reduced.

According to the fourth aspect of the present invention, since the support body has the traveling guide means having the contact portion that comes into contact with the side wall of the container, the traveling performance of the support body is improved. In this case, since the width of the container in the traveling direction is constant, such contact-type guide means can easily guide the traveling at low cost. Further, since no sensor or the like is used, it is unlikely that an operation error or failure will occur.

In this case, if the length of the contact portion is set to a predetermined length which is equal to or longer than a certain length, the guide property is improved and the running property is further improved. For example, even if the wall surface of the container is a corrugated plate or the wall surface is uneven, if the predetermined length of the contact portion is set to be one pitch or more of the corrugated portion, the contact portion fits into such a recess. Never. As a result, the vehicle cannot run or the support does not meander or vibrate. Further, if the adjusting means for adjusting the widthwise distance of the contact portion is provided, the traveling guide means can cope with containers having different widths, and the adaptability of the container drying device is improved.

According to the fifth aspect of the invention, since the nozzle portion has the swinging mechanism for changing the direction of the opening, the blowing direction of the hot air can be adjusted. Therefore, it is possible to change the position of the surface to be dried on which the hot air hits. As a result, the optimum opening direction can be selected in relation to the traveling state of the support, or the temperature rising gas can be applied to the corner portion between the floor surface and the front end wall by tilting forward.

According to the sixth aspect of the invention, since the temperature raising means has the combustion device for burning the fuel, it is possible to generate hot air by utilizing the combustion heat of the fuel. For example, if an electric heating device is used as the temperature raising means, the operation itself is extremely simple, but it consumes a very large amount of electric power, so that such electric power may not be obtained in the container yard.
Moreover, since the support runs, it is difficult to handle the cable for supplying a large amount of electric power. Further, when the same heat energy is applied to the gas, the fuel is once converted into electricity and further converted into heat, resulting in a large energy loss. Therefore, by utilizing the heat of combustion, the container can be dried at low cost and with low energy consumption.

When the combustion heat of the fuel is used by providing a combustion device, a method of using a heat exchanger to exchange heat between the combustion gas and air to raise the temperature of the air and a mixing means are used. There is a method of providing and mixing the combustion gas generated in the combustion device with the air. However, in the former method using a heat exchanger, heat exchange between gas and gas is caused, heat exchange performance is poor, the heat exchanger has a large size, and the container drying device becomes large. On the other hand, since the combustion gas has a high temperature and it is not easy to obtain a large amount of gas by itself, the combustion gas itself cannot be used as hot air for drying the container. If the mixing means is provided as in the latter method, the temperature of the combustion gas can be lowered to an appropriate temperature, and the amount of hot air required to heat the heated portion can be easily produced with a small-sized device. In this case, if the air supply means is provided on the downstream side of the mixing means, an induced air supply system is formed, so that a high wind pressure is not required in the burner portion for burning the fuel. As a result, the burner has a simple structure and is inexpensive.

According to the seventh aspect of the present invention, since the drying device loading surface of the container drying device transporting carriage is set to the same height as the floor of the container, the drying device can be loaded on the structure by self-propelling. When the container is dried in the container yard, the drying device has to be moved between many containers arranged in parallel. However, since the container is placed on sleepers, etc., its floor is at a low level, and ordinary transport vehicles such as trucks cannot load the dryer on their own, and the transfer means such as crane trucks cannot be used. Will also be needed. According to the carrier truck of the present invention, such a device is not necessary at all, and the drying device can be moved in a short time by a simple operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 to 3 are side views, a plan view and a front view, respectively, showing the overall construction of a container drying apparatus of an embodiment. The drying device 100 includes a nozzle portion 1 having an opening 1a facing a floor surface 301 as a portion to be dried of a container.
A flexible duct 2 and an air supply fan 3 as an air supply means for sending hot air, which is a mixed gas of air and combustion gas, to the nozzle portion 1, and a hot air generator 4 as a temperature raising means for raising the temperature of the gas. And a trolley 5 as a support for supporting these, and a traveling drive device 6 and wheels 7 as traveling means for traveling the trolley 5.

The container dryer is also equipped with a seal plate 8 as shown in FIG. 4 as a seal member appropriately supported by the carriage 5. The seal plate 8 covers the floor surface 301 from the nozzle portion 1 to the end portion of the carriage 5 as a predetermined rear portion at a height position as shown in the side shapes of FIGS. 1 and 4. Here, the predetermined range is determined so that the drying effect becomes large in relation to the length of the carriage 5, the amount of air supplied, the traveling speed of the carriage, and the like. Further, when the floor surface 301 is washed with water, the vicinity of the lower ends of the both side walls 302 and the front end wall 303 also gets wet due to water splashing. However, in this part, even if water is splashed, it falls off, so the degree of moisture absorption is
Smaller than Therefore, the area up to just above the floor is the target of drying. The height of the seal plate 8 from the floor surface 301 is determined in consideration of the drying effect of this portion as well.

In this embodiment, in order to discharge the hot air blown from the nozzle portion 1, an exhaust fan 9 is provided as a forced exhaust means at the exhaust portion behind the seal plate 8. Thus, when the seal plate 8 is set at a low position and forcedly exhausted by the exhaust fan 9, the flow velocity of the hot air with respect to the floor surface 301 increases, heat exchange between the two is promoted, and the drying time of the floor surface 301 is increased. As the length becomes shorter, the exhaust temperature lowers, and energy is effectively used. However, it is also possible to raise the height of the seal plate 8 a little more so that a space is provided between the end of the seal plate 8 and the floor surface 301 and the space is used as an exhaust portion. In this way, the equipment cost is low.

It is also possible to increase the width of the nozzle portion 1 in the traveling direction without providing the sealing plate 8 and heat exchange with the floor surface 301 only at this portion. In this case, the amount of hot air increases and the drying time becomes long.

The traveling drive device 6 for the carriage 5 is provided with a traveling motor 6a, a belt 6b for transmitting the rotation thereof, a drive pulley 6c, and a drive shaft 6d to which the drive motor 6a is fixed. If necessary, such a drive device 6 may be provided with a speed reducer, a transmission, or the like. Further, the traveling speed of the carriage 5 may be adjusted by setting the rotation speed of the traveling motor 6a in multiple stages or by changing the speed of the motor.

The trolley 5 also serves as a guide means having a crawler portion 10a as a contact portion for contacting both side walls 302 of the container, and as a guide means, a crawler device 10 and a mounting plate 11, and in this embodiment, a container of the crawler portion 10a. It is equipped with a traveling width adjusting mechanism 12 which is an adjusting means for adjusting the widthwise distance.

The crawler device 10 is formed so as to surround a roller 10c rotatably supported by a support plate 10b by a crawler portion 10a, and is attached to a mounting plate 11 via a leaf spring 11a. Crawler part 1 made of rubber
0a and the leaf spring 11a allow the crawler device to come into contact with the side wall at an appropriate pressure, thus forming a stable traveling guide. Further, even if the wall surface is uneven, the shock caused by the unevenness is absorbed, and the carriage 5 does not vibrate or shake during traveling.

In the present embodiment, the crawler portion 10a has a predetermined length so as to straddle a plurality of ridges and valleys so that the side wall of the container can be guided satisfactorily even if it is a corrugated plate. However, in a container drying device intended only for a container whose side wall is made of a flat plate, the structure may be simplified by using a rubber roller or the like without using the crawler part 10a as the contact part.

The traveling width adjusting mechanism 12 has a link 12a and a fulcrum 12b for swingably supporting the mounting plate 11, one end of which is attached to the mounting plate 11 and the other end of which is a stopper portion 12c.
The swing arm 12e is engaged with the fulcrum 12d and is rotatably supported by the fulcrum 12d. By providing the adjusting means in this way, even if the inner dimension of the container varies to some extent depending on the type of container, such as a normal container or a container with a thick wall for heat insulation such as a refrigerating container, it is possible to cope with this. Good travelability can be maintained by adjusting the position of the crawler device. Also, ISO standard 8f
It becomes possible to support containers other than the t-width container, and the container drying device becomes versatile.

The nozzle portion 1 extends over substantially the entire length of the container in the width direction. In this way, the entire width can be processed in one run. Further, when covering the portion to be dried, the vertical seal on one end side in the width direction can be omitted, and the sealing device can be simplified. However, for example, the nozzle portion may be ½ of the width of the container, the carriage may be made small, and the drying device may be made small and lightweight. In this case, the traveling guide is provided on one side wall of the container, or the traveling guide has a structure capable of extending and contracting in the width direction so as to reach both side walls.

For the nozzle portion 1, a hanging arm 13a is provided as a swinging mechanism 13 for changing the direction of the opening 1a.
A fixing member 13b rotatably engaged with the fixing member 13b and fixed to the nozzle portion 1, and an adjusting plate 1 attached to the nozzle portion 1.
3c, and an adjusting plate 13c for holding the orientation of the nozzle part 1 by stopping this rotation angle within a certain range.
A stopper 13d for engaging with 3a is provided.

When such a mechanism is provided, as shown by the solid line in FIG. 1, the blowout port 1a of the nozzle portion 1 is normally located on the floor surface 301.
The posture can be maintained so as to be opposed to the
When the container reaches the vicinity of the front end wall 303 of the container, it is detected by, for example, a proximity switch (not shown) or the like, and the carriage 5 is stopped at an appropriate position to prevent the nozzle portion 1 from colliding with the wall and to adjust the adjusting plate. 13c hits the wall and inclines as shown by the chain double-dashed line in the figure, and accordingly, the outlet 1a of the nozzle part 1 also inclines, blowing hot air diagonally forward,
The corner portion between the floor surface 301 and the front end wall 303 can be applied to this portion to be sufficiently dried.

In this embodiment, the swing mechanism has a structure only corresponding to the corner portion as described above, but a drive unit may be provided in the swing mechanism so that the swing mechanism can be remotely or automatically swung. Good. By doing so, the mechanism becomes complicated, but by oscillating the nozzle part 1 to change the part on which the hot air hits, or by optimizing the hot air blowing angle in relation to the traveling state of the carriage 5 and the like. The drying efficiency can be improved. For example, when the drying device is started from the initial position at the end of the container, the vicinity of the end of the container can be well dried by stopping for a certain period of time and rocking the nozzle unit 1.

FIG. 5 shows a schematic structure of the hot air generator 4.
The hot air generator 4 includes a fuel tank 41 for oil or the like shown in FIGS. 1 and 2, a burner section 42, a fuel pump 43, a combustion fan 44 that sends combustion air, a combustion chamber 45, and an outside air. A casing 46 that surrounds the combustion chamber so as to be sucked, and a baffle plate 47 that mixes the combustion gas and the outside air are provided.
Thus, if the temperature of the outside air is raised by the combustion device that burns the fuel, the energy efficiency is extremely good. Further, since the combustion gas and the air are mixed, a heat exchanger or the like is not required, 100% heat can be exchanged, and the device can be downsized.

The mixed gas discharged from the casing 46 is sucked into the blower fan 3 through the duct 48. Then, the outside air is also sucked from the duct 48 portion, mixed with the mixed gas, becomes hot air for drying, is sucked by the air supply fan 3, and is sent from the duct 2 to the nozzle portion 1. Finally the nozzle part 1
The temperature of the hot air blown out from the air outlet 1a is 100 ° C
It is a degree. Thus, by arranging the fan on the downstream side of the air mixing section to form a mixing induction type air supply system, the desired relatively low temperature hot air can be easily obtained with a simple device.

In this embodiment, the direct combustion type temperature raising means is used as described above, but when the drying apparatus is small, an electric heater or other air heating apparatus is used. May be. Further, even in the case of the combustion type, it is possible to mix the combustion gas and air by a method different from that of the embodiment or to use a heat exchanger.

The container dryer is preferably operated remotely or automatically. In the present embodiment, the control panel 14 shown in FIGS. 1 and 2 can be operated by switching between automatic and remote manual operation. For example, the speed control is selected according to a specific purpose when the device is used, such as constant speed running, intermittent running in which starting and stopping are repeated, running control in which starting and stopping and running speed are programmed. In some cases, the exhaust temperature may be detected, and when the exhaust temperature becomes equal to or higher than a predetermined temperature, it may be determined that the floor surface has sufficiently risen in temperature and is dried, and intermittent traveling control may be performed so that the carriage 5 travels for a certain distance. .

FIG. 6 shows a container drying device carrier 200.
2A is a plan view, and FIG. 3B is a side view showing a state in which the container drying device 100 is placed. The transport carriage 200 includes a structure 201 integrally formed with a loading surface 201a on which the container drying device 100 is placed,
It has a moving motor 202 as a moving means for moving the structure 201, a drive shaft 203, and wheels 204. As shown in FIG. 7B, the height of the loading surface 201a is approximately the same as the floor 301 of the container 300.

In this embodiment, a transfer plate 205 having a width that allows the wheels 7 of the drying device 100 to pass through is provided. If such a transfer board is provided, the floor of the container and the loading surface 201a are connected by the transfer board even if the structure 201 is installed apart from the end of the container opened when the container is dried. Then, the drying device 100 can be mounted on the structure by self-propelled from the floor. As a result, it becomes easy to move the carrier truck between the containers. Moreover, as shown in FIG.
A guide plate 206 for guiding the traveling of the drying device 100 is provided if necessary. Transfer plate 205 and guide plate 2
06 may be portable.

The carrier vehicle 200 further includes a drying device 100.
A generator 250 that supplies power to If the generator is provided in this way, it is not necessary to provide a power supply facility at the container drying place in the container yard. In this case, since the power generation means is provided not on the drying device that travels inside the container but on the external transport carriage, the drying device itself is small and lightweight, and handling during traveling and transfer during drying becomes easy. The power source required here is the traveling motor 6a of the drying device 100, the air supply fan motor 3a, the fan and pump of the hot air generator 4, the drive motor of the exhaust fan 9, and the automatic control panel 1.
4. A power source for the drive motor 202 and the like of the carriage 200. A very large amount of electric power is required to generate hot air with the electric heater, but since the electric heater is not used in this embodiment, the generator 250 is of a size that can be mounted on the dryer transport carriage 200 as illustrated. become. As shown in FIG. 7, the carriage 200 is provided near the outside of the container 300 and is used for moving between the containers arranged in parallel.

With the above-mentioned structure, the container dryer is operated as follows. As shown in FIG. 7, when the drying device 100 is installed on the inlet side of the container 300, the power cable 251 is coupled from the generator 250 of the carrier 200 via the cable reel 16. Also, the adjusting device 12 is adjusted so that the crawler device 10 contacts both side walls 302 of the container with an appropriate pressure. In the control panel 14,
The traveling speed can be selected, and any speed is selected in advance. In this state, for example, the control panel 14 selects automatic operation, and a start button (not shown) is pressed.
As a result, the hot air generator 4 starts, and the air supply fan 3 and the exhaust fan 9 also start.

When the hot air generator 4 is in the steady operation state, 1
The hot air of about 00 ° C is blown out from the air outlet 1a of the nozzle portion 1, hits the floor surface 301 directly below the air outlet 1a, and then is held in the seal plate 8 and sucked by the exhaust fan 9. During this time, hot air flows over the floor surface 301 to apply heat to the floor surface to evaporate the moisture contained therein and dry the floor surface. After a certain period of time has elapsed for the dryer 100 to dry the portion immediately below it at the initial position, the traveling motor starts and the drying apparatus 100 starts traveling. At this time, the trolley | bogie 5 is guided by the both side walls 302 via the crawler device on both sides, and it runs stably smoothly.

When the truck 5 moves forward while drying the floor surface 301 and a portion slightly above it and below the seal plate 8 and approaches the front end wall 303, a proximity switch (not shown) detects this and the truck 5 travels. Stop. At this time, the adjustment plate 13c of the nozzle unit 1 hits the front end wall 303, the nozzle unit 1 is tilted forward, and hot air is jetted obliquely forward.
In this state, if a certain time has passed and the corner has dried,
The traveling motor 6a is reversed to move the carriage 5 backward.

When a sensor (not shown) attached to the rear end of the truck 5 detects the initial position of the truck 5, the traveling motor 6a is stopped and the truck 5 is stopped. Also, the hot air generator 4 is stopped. After that, the air supply fan 3 and the exhaust fan 9 are maintained in an operating state for a certain period of time to cool down the apparatus, and then these are stopped. This completes the entire drying process. According to the experiments conducted by the inventors, the container drying apparatus and the operating method as described above were used to remove the container after washing with water.
In 0 to 30 minutes, the desired water content on the floor surface could be dried to about 15%.

When the drying of one container is completed, the trolley 5 is further retracted, and as shown in FIG.
At the end of 00, the dryer transporting carriage 200 waiting at the end is loaded. Then, as shown in (a) of the same figure, it is transferred to the next container and dried. Then, such operations are sequentially repeated to dry a certain number of containers. According to such a method, a large number of containers can be dried within a fixed short time.

In the above, the case of mainly drying the floor surface of the container has been described. However, the container drying apparatus of the present invention can be used for drying wall surfaces, if necessary. In that case, another duct is taken out from the blower 3 shown in FIG. 1, vertical nozzles are provided along both wall surfaces, and ducts for the floor surface, the side wall, and the end wall are switched and used.
