TECHNICAL FIELD OF THE INVENTION
The present invention relates to a tank truck, and more particularly, to a structure of a tank mounted on the tank truck.
[0002]
[Prior art]
FIG. 6 schematically shows the structure of a conventional tank truck 200. The tank lorry 200 includes a lorry main body 210 and a chassis 221 provided behind the lorry main body 210, and a tank capable of storing a liquid (chemical liquid or the like) in an internal space above the chassis 221. 220 is mounted. In the actual tank lorry 200, the tank 220 is covered with an exterior or the like. However, in order to better understand the tank configuration, the exterior or the like is illustrated only by a two-dot chain line.
[0003]
The tank lorry 200 is a large tank lorry for loading a liquid of about 10 m ³ , and the tank 220 is composed of a first tank 201, a second tank 202, and a third tank 203 which are separated from each other.

[Problems to be solved by the invention]
In the tank 220 mounted on the tank lorry described above, pipes 204 and 205 are provided on the lower surface side of the tank 220 to connect the internal spaces of the tanks 201, 202 and 203 separated into three. However, even after the liquid is extracted from the tank 220, the liquid often remains in the pipes 204 and 205. In particular, when a chemical solution or the like remains, corrosion occurs in the pipes 204 and 205 and the liquid leaks. The problem described above may occur.
[0008]
The inner surfaces of the tanks 201, 202, and 203 are lined with a corrosion-resistant resin film or the like. However, it is necessary to apply a lining process to each of the tanks 201, 202, and 203. This is a factor that increases manufacturing costs.
[0009]
Therefore, the present invention has been made to solve the above-mentioned problem, and it is an object of the present invention to provide a tank mounted on a tank lorry and having a large storage capacity with only one tank configuration without separation. .
[0010]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, a tank according to the present invention has a substantially cylindrical shape, and has a main body tank capable of containing a liquid in its internal space, and is provided inside the main body tank so as to cross the internal space. And an internal partition for partitioning the battery. Furthermore, the internal partition has a first internal partition and a second internal partition, each of which has a curved shape with a concave center, and the first internal partition and the second internal partition are such that their convex surfaces face each other. It is arranged.
[0011]
As described above, by adopting the main body tank structure having a single configuration, when the liquid stored in the tank is discharged, the region where the liquid remains does not exist. Occurrence can be eliminated.
[0012]
In addition, by providing an internal partition that crosses the internal space, the rigidity of the tank itself is increased (rib effect), and when the liquid is contained inside, the large sway of the liquid due to the start and stop of the tank lorry is prevented. (Wave breaking effect), and it is possible to prevent a decrease in the starting performance and stopping performance of the tank lorry.
[0013]
Furthermore, by arranging the first internal partition and the second internal partition so that the convex surfaces are opposed to each other, the concave surfaces of the first internal partition and the second internal partition can be used regardless of whether the tank lorry starts or stops. The side can receive inertial force from the liquid. Here, when a force is applied on the convex surface side, a compressive force is applied to the internal partition, and when an unexpected inertial force is received from the liquid, the convex portion of the internal partition is deformed in a concave direction. There is a fear. On the other hand, in the case of the present application, in both cases of starting and stopping, the structure is configured to receive a force on the concave surface side, so that only the tensile force is generated in the internal partition, so that the liquid is not applied to the internal partition. Even when an unexpected inertial force is applied, the inner partition does not deform.
[0014]

(Action / Effect)
As described above, according to the tank in the present embodiment, by adopting the structure of the main body tank 101 having one configuration, when the liquid stored in the tank 103 is discharged, the region where the liquid remains does not exist, and as in the conventional case. It is possible to eliminate the occurrence of liquid leakage due to the remaining of the liquid. Further, by providing the front inner partition wall 110 and the rear inner partition wall 110 as internal partition walls, the rigidity of the tank 103 itself is increased to obtain a rib effect, and the tank lorry 200 can be started / stopped in a state in which liquid is stored inside. A wave-preventing effect of preventing the accompanying large swaying of the liquid can be obtained, and it is possible to prevent a decrease in the starting performance and stopping performance of the tank lorry 200.

Further, by arranging the first inner partition wall 110a and the second inner partition wall 110b such that the convex surfaces face each other, the first inner partition wall 110a and the second inner partition wall 110b can be used regardless of whether the tank lorry 200 starts or stops. The concave surface of the internal partition 110b can receive an inertial force from the liquid.
[0032]
Here, when a force is applied on the convex surface side, a compressive force is applied to the internal partition, and when an unexpected inertial force is received from the liquid, the convex portion of the internal partition is deformed in a concave direction. There is a fear. On the other hand, in the case of the present application, the force is applied to the concave surfaces of the first internal partition 110a and the second internal partition 110b regardless of whether the vehicle starts or stops. Also, since only a tensile force is generated in the second inner partition 110b, even when an unexpected inertial force is applied from the liquid to the first inner partition 110a and the second inner partition 110b, the inner partition is deformed. I will not.
[0033]
Further, even when the internal space of the tank 130 is divided by the first internal partition 110a and the second internal partition 110b, the internal space is communicated by the first opening area 112 and the second opening area 113. Therefore, it can be used as one internal space, and the efficiency of liquid filling and discharging operations can be improved.
[0034]
The above-described embodiment disclosed this time is an example in all respects. Therefore, the technical scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
[0035]
