It is the schematic by the right side view which shows the positional relationship of the fixture in an air blow port.

Next, an embodiment of the present invention will be described. For convenience of explanation, the following expressions of directions are based on the direction shown in FIG. 1 for the vertical direction. Regarding the front-rear direction, the left side in the state shown in FIGS. 1, 2, and 4 is positioned forward of the vehicle when mounted, so it is defined as front, and the right side is positioned rearward when mounted, so is defined as rear. Further, the width direction is a direction that coincides with the vehicle width direction when the vehicle is mounted on the vehicle, and is the vertical direction shown in FIG.

The drying container 1 according to this embodiment is one component of the drying container system S shown in FIGS. 1 to 3. FIG. Here, the dry container system S will be described. The dry container system S is mainly composed of a dry container 1 , an airflow supply mechanism 2 and a connecting pipe 3 . The drying container 1 is constructed so as to be mounted on a vehicle (not shown). Inside the drying container 1, a large number of wood chips (hereinafter referred to as "chips"), which are granular materials, are accommodated. A large number of stored chips are dried by blowing air to evaporate the water adhering to the outer surface and the water contained in the wood structure. Dried chips are used, for example, in woody biomass power generation. Drying facilitates combustion during power generation and reduces the weight by the amount of water removed, which is advantageous for transportation, for example.

The airflow supply mechanism 2 is a mechanism capable of generating hot air, for example, and includes an air blower and a heater (not shown). Note that the heat source for heating the airflow can be provided outside the airflow supply mechanism 2, for example, when heating is performed using exhaust heat from another device. Heating of the airflow can be appropriately performed according to the degree of dryness and the amount of chips accommodated in the drying container 1 . Also, depending on the situation, it is possible to perform only air blowing without performing heating. The connecting pipe 3 is a pipe that connects the drying container 1 and the airflow supply mechanism 2 to send the airflow (hot air) generated by the airflow supply mechanism 2 to the drying container 1, and a pipe or a hose can be used. The connection of the connecting pipe 3 to the drying container 1 will be described later. In this embodiment, a hose (duct hose) having a circular cross section is used.

The drying container 1 has a substantially rectangular parallelepiped shape similar to a general vehicle-mounted container, and when used as a drying container system S shown in FIGS. is a box-like body closed except for the blower port 116 to which the connecting pipe 3 is connected. Chips are introduced into the drying container 1 from the upper surface thereof.

The drying container 1 can receive the airflow (hot air) sent from the airflow supply mechanism 2 via the connecting pipe 3 at the bottom, which is the portion near the bottom, and then apply the airflow to a large number of accommodated chips. It has a double bottom structure. For this purpose, the drying container 1 mainly comprises a container body 11 , a deck 12 , a support 13 and a sub-support 14 .

The container main body 11 is a box-shaped portion that appears in the appearance of the drying container 1 . A hook engaging portion 112 protrudes from the front side surface 111 to which a hook provided on a movable arm on the vehicle side is hooked when the drying container 1 is mounted on the vehicle. Further, a roller 113 that rolls on the ground or road surface is provided at the rear of the bottom portion when the vehicle is loaded and unloaded. A pair of rollers 113 are provided in the width direction of the container body 11, as shown in FIG. Further, a leg portion 114 is provided in front of the bottom portion to be grounded together with the roller 113 when installed. A pair of the legs 114 are also provided in the width direction of the container body 11 .

As shown in FIGS. 1 and 3, a blower port 116 for communicating between the inside and outside of the container body 11 and to which the connecting pipe 3 can be connected is provided at the lower portion of the rear side surface 115 of the container body 11 and at the center in the width direction. is provided. The air blowing port 116 of this embodiment has a short cylindrical shape that protrudes rearward from the rear side surface 115 of the container body 11 and in the normal direction of the rear side surface 115 . A connecting pipe 3 for blowing air into the container body 11 is connected to the air blowing port 116 . The blower port 116 has a circular shape when it faces directly (when facing the rear side surface 115). Further, as shown in FIG. 3, a door 1151 is provided on the rear side surface 115 of the container body 11. For example, when chips are taken out or the inside of the container body 11 is cleaned, the air outlet 116 can be opened. can be opened except for the surrounding area. Further, the bottom and side surfaces of the container body 11 are reinforced by forming ribs or the like.

Next, the deck 12 is a plate-like portion having a plurality of through holes 121 . . An airflow retention space 15 (see FIG. 5) is formed between the bottom surface of the container body 11 and the deck 12 . The air outlet 116 communicates with the outside of the container body 11 between the bottom surface of the container body 11 and the deck 12 . In order to introduce a large amount of airflow, the height dimension of the air blowing port 116 is set larger than the distance in the height direction between the bottom surface of the container body 11 and the deck 12 . For this reason, a ventilation guide portion 16 for adjusting the height dimension is provided inside the container body 11 . The air-blowing guide portion 16 is a box-shaped portion having an isosceles triangular shape in a plan view as shown in FIGS. 2 and 4 and a trapezoidal shape in a vertical cross-sectional view as shown in FIG. A rear end portion of the internal space of the air guide portion 16 is connected to the air blow port 116 . A lower end portion of the internal space of the air guide portion 16 is connected to the airflow retention space 15 . The upper surface of the air-blowing guide portion 16 is not provided with openings or through-holes, except for openings that are unavoidable due to manufacturing reasons. Therefore, the airflow (hot air) introduced from the air blowing port 116 flows into the airflow retention space 15 via the air blowing guide portion 16 . In this manner, the air blowing port 116 communicates with the outside of the container body 11 via the air blowing guide portion 16 .

The deck 12 is constructed by arranging a plurality of deck veneers 12a . . . 12a. In this embodiment, the deck 12 is composed of four deck veneers 12a . . . 12a arranged in the front-rear direction. However, it is not limited to this, and the deck veneers 12a . A punching plate is used as each deck veneer 12a in this embodiment. However, the present invention is not limited to this, and for example, a combination of a wire mesh and a member for adjusting the aperture ratio (a plate-like member provided with slits, etc.) may be used, and various configurations can be selected.

Next, the support 13 is fixed to the bottom of the container body 11 together with the sub-support 14, and as shown in FIG. . The support 13 has a sideways U-shaped vertical cross-section, and extends parallel to the direction of the airflow F<b>1 introduced into the container body 11 from the blower port 116 (front-rear direction). In this embodiment, the support 13 extends from the rear side 115, which is one side of the container body 11, toward the front side 111, which is the other side facing the one side. The sub-support 14 is orthogonal to the support 13 and connects the support 13 and the widthwise side surface of the container body 11 . In this embodiment, sub-supports 14 . . . 14 are provided in three rows in the front-rear direction.

The support 13 is provided across the deck 12 and the bottom surface of the container body 11 . Therefore, the space on the bottom side (lower side) than the deck 12 in the container body 11, that is, the airflow retention space 15 is partitioned in the width direction. However, this support 13 is shorter than the distance between the front side 111 and the rear side 115 of the container body 11 . A portion of the rear end portion of the support 13 that does not partition the airflow retention space 15 is covered with the above-described air-blowing guide portion 16 .

As shown in FIG. 5 , a fixture 1171 is provided on the outer peripheral portion of the blower port 116 . In this embodiment, a bracket 1161 is fixed to the outer peripheral surface of a short cylindrical portion protruding from the rear side surface 115 of the blower port 116 , and a fixture 1171 is provided on the outer peripheral surface of the bracket 1161 . That is, the "peripheral portion" corresponds to the outer peripheral surface of the cylindrical portion in this embodiment. However, it is not limited to this, and the rear side surface 115 (outer surface) of the container body 11 may correspond. The fixture 1171 can be connected to and separated from a fixed fixture 1172 of the connecting pipe 3 , and can fix the connecting pipe 3 to the blower port 116 when connected. By connecting the fixture 1171 and the fixture 1172 together, the connection pipe 3 can be easily fixed to the blower port 116 . In addition, since the connecting pipe 3 can be fixed to the blower port 116 only by the set 117 of the fixing member 1171 and the member to be fixed 1172, there is no need to prepare a separate band or the like, so there is no need to worry about losing the blower port. No special consideration is required for managing parts for fixing 116 .

In this embodiment, a well-known "snap lock" is used for the set 117 of the fixture 1171 and the fixture 1172 to be fixed. If this set 117 is a general “snap lock”, one of the fixture 1171 and the fixture 1172 has a hook 1173 . This hook 1173 is the curved portion shown in FIG. In addition, the other of the fixture 1171 and the fixture 1172 is in a state of being hooked by an operating portion (lever) 1174 that receives force for operating the fixture 1171 and the fixture 1172 and a hook 1173 . and a hooking tool 1175 that is held in a state of being hooked on the hook 1173 by generating a tensile force with the hook 1173 by operating the operating part 1174 in . However, the shape shown in FIG. 5 is just an example, and the shape is not limited to this shape.

The hooking tool 1175 is, for example, a polygonal or circular frame-like body, a part of which is rotatably supported by the operation part 1174 and the other part of which is hooked on the hook 1173 . . Part of this hook 1175 may incorporate a spring that exerts a compressive force. By constructing the set 117 of the fixing tool 1171 and the fixed tool 1172 like this "snap lock", attachment and detachment of the connecting pipe 3 to the blower port 116 can be easily performed.

At least three fixtures 1171 are provided along the circumferential direction of the circular blowing port 116 . As shown in FIG. 6, when a line passing through one of the three fixtures 1171 (referred to as a reference fixture 1171A) and the radial center 116C of the air blowing port 116 is defined as a reference line 116L, the standard The two fixtures 1171B and 1171C, excluding the fixture 1171A, are distributed and arranged in one side area and the other side area sandwiching the reference line 116L.

In this embodiment, the distance between the reference fixture 1171A and the two fixtures 1171B and 1171C and between the two fixtures 1171B and 1171C are based on the radial center 116C of the blower port 116. They are angularly separated by about 120 degrees. In this way, the fixtures 1171 can be distributed in the circumferential direction around the outer circumference of the blower port 116, and more specifically, evenly (or substantially evenly) arranged. The combination (snap lock) 117 of the tool 1172 can stably fix the blower port 116 and the connecting pipe 3 .

The fixture 1171 extends in the axial direction of the short cylindrical blower port 116 (airflow direction at the blower port 116 ), that is, in the normal direction of the rear side surface 115 of the container body 11 . Correspondingly, the extending direction of the hook 1173 is a direction perpendicular to the normal direction. In addition, the fixture 1171 has a contact surface with the fixture 1172 . This abutting surface is the inner surface of the hook 1173 and is the surface facing the direction of the air flow toward the air blowing port 116 (air blowing direction). In this embodiment, the "facing surface" is a surface orthogonal to the blowing direction. However, the surface is not limited to this, and may be a surface that intersects the blowing direction. The hook 1175 of the fixture 1172 contacts this contact surface at the time of coupling. Therefore, the direction of the tensile force generated between the fixing member 1171 and the member to be fixed 1172 of the connecting pipe 3 at the time of coupling is the direction of the reaction force generated in the connecting pipe 3 by the airflow toward the blower port 116, that is, the direction of the connecting pipe. It is the axial direction in the tube 3 and coincides with the direction away from the rear side 115 of the connecting tube 3 . By configuring in this way, the reaction force generated in the connecting pipe 3 can be counteracted with a simple configuration.

The "blowing direction" is the direction in which the blowing port 116 opens. It is also the normal direction or plate thickness direction of the rear side surface 115 . In this embodiment, it is the axial direction in the short cylindrical portion projecting from the rear side surface 115 at the air outlet 116 . However, even if the cylindrical portion is not provided as in the present embodiment and the air blowing port 116 is configured only by a hole penetrating the rear side surface 115, the air blowing direction is set to the opening of the air blowing port (hole) 116. It can be defined by a direction or an axial direction.

Incidentally, as shown in FIG. 3, the drying container 1 can further include a blower port cover 4 that closes the blower port 116 when not in use (for example, when the drying container 1 is mounted on the vehicle). In this case, the fixing member 1172 having the same shape as that of the connecting pipe 3 is also provided on the blower port lid 4 . Therefore, the air blower cover 4 can be fixed to the air blower opening 116 by connecting the fixing member 1171 of the air blower opening 116 and the fixed member 1172 of the air blower cover 4 . As shown in the figure, the air vent lid 4 is connected to the container body 11 by a wire 41 so that when the air vent lid 4 is removed from the air vent 116, it does not dissipate and stays close to the air vent 116. .

As mentioned above, although one embodiment was taken up and described about this invention, this invention is not limited to the said embodiment. For example, although the drying container 1 of the above-described embodiment is configured to be mounted on a vehicle, it is not limited to this, and may not be mounted on a vehicle. In this case, the drying container 1 may be of a fixed type that does not move at a fixed position, or may be of a portable type that can be moved as appropriate. In particular, when it is not intended to be mounted on a vehicle, the drying container 1 is not limited to a substantially rectangular parallelepiped shape as in the above embodiment, and can be of various shapes such as a cylindrical shape.

Moreover, the upper surface of the drying container 1 of the above embodiment was always open. However, it is not limited to this, and it is also possible to provide a lid made of a hard or soft material whose upper surface can be closed if necessary, for example to protect the chip from rain water.

In addition, the air outlet 116 of the above-described embodiment was provided on the rear side surface 115 of the container body 11 . However, it is not limited to this, and the air outlet 116 can also be provided on the front side surface and the width direction side surface of the container body 11 .

Further, the blower port 116 of the above-described embodiment has a short cylindrical shape. However, it is not limited to this, and may be configured only by a hole passing through the rear side surface 115 of the container body 11 .

Moreover, the fixture 1171 can also be provided on the side wall (rear side 115 or the like) of the container body 11 . Even in this case, if the fixture 1171 has a contact surface with the fixture 1172, the force component in the direction of the airflow toward the air blowing port 116 (air blowing direction) is applied to the connecting pipe 3 in the axial direction and the direction in which the connecting pipe 3 separates from the rear side surface 115 . Therefore, the reaction force generated in the connecting pipe 3 can be counteracted.

Also, although the sets 117 of the fixtures 1171 and the fixtures 1172 are provided in three sets (three pieces each) in the above-described embodiment, four sets (four pieces each) or more may be provided. The distribution of each group 117 in this case can be performed in the same manner as in the above-described embodiment.

Further, in the above-described embodiment, a "snap lock" is used as the set 117 of the fixing tool 1171 and the fixed tool 1172, but other various configurations that can be combined and separated can be employed. For example, it can have the same configuration as the “lock member” described in Japanese Patent Application Laid-Open No. 2016-210592 filed by the applicant. This "lock member" has a rocking piece having a groove at its tip, and is configured to be able to hold the rod-like member in the groove of the rocking piece (coupled state). Also, it is possible to configure such that the connected state can be held by inserting a pin into a hole (through hole or bottomed hole). Moreover, it is possible to configure such that coupling and separation can be performed by magnetic force of a permanent magnet or the like.

In addition, although the object to be dried in the dry container system S is wood chips in the above-described embodiment, it is not limited to this. etc., can be made into various granules. Moreover, the moisture may be present only on the outer surface, or may be present both on the outer surface and inside.
