  The liquid transfer vehicle according to the present embodiment is a vehicle for transferring a chemical that is a mixed liquid obtained by mixing a plurality of types of liquids. Of course, the liquid mixture transferred by the liquid transfer vehicle is not limited to chemicals.

  As shown in the figure, the liquid transfer vehicle 10 according to the present embodiment includes a tractor 12 that travels with an engine 11 that is an internal combustion engine, and a trailer 13. The trailer 13 is detachably connected to the tractor 12 via a connecting device 15 provided on the pulling portion 14 of the tractor 12. A liquid tank container 16 is placed and fixed on the loading platform of the trailer 13. The liquid tank container 16 includes a liquid tank 18 in the container body 17. Note that different types of trailers 13, that is, trailers 13 to which different types of liquid tank containers 16 are fixed, can be connected to the traction section 14 of the tractor 12.

  The liquid tank 18 is formed of, for example, SUS316 or the like and has a capacity of about 20 tons. Further, on the outer wall of the liquid tank 18, a liquid tank side pipe 19 is provided on the rear side in the traveling direction of the tractor 12 for carrying the liquid into the liquid tank 18 or discharging the liquid in the liquid tank 18 to the outside. . For example, in the present embodiment, a pressure-feeding means, for example, a rotary pump 20 for pressure-feeding the liquid into the liquid tank 18 or pumping the liquid in the liquid tank 18 to the outside is mounted on the trailer 13. 20 is connected to the liquid tank side pipe 19. Specifically, the rotary pump 20 is provided with trailer-side piping 21 on the inflow side and discharge side, and the trailer-side piping 21 and the liquid tank-side piping 19 are connected. That is, by driving the rotary pump 20, two types of liquids are pumped from the outside into the liquid tank 18, and the liquid (chemicals) in the liquid tank 18 passes through the trailer side pipe 21 to the outside, for example, the destination. It is pumped to a storage tank. Needless to say, the liquid tank 18 may be loaded from a manhole (not shown) provided in the upper part of the liquid tank 18. The rotary pump 20 is driven by the engine 11 of the tractor 12. For this reason, the rotary pump 20 can be driven without providing a dedicated power source. Of course, the rotary pump 20 may be driven by a dedicated drive source.

  The liquid tank 18 is provided with a stirring device 22 that stirs the liquid carried into the liquid tank 18, for example, two kinds of liquids that are raw materials of chemicals in this embodiment. In this embodiment, the stirring device 22 is fixed to the outer wall of the liquid tank 18. The position at which the stirring device 22 is fixed to the liquid tank 18 is not particularly limited, but it is preferable that the outer wall of the liquid tank 18 be a front surface in the traveling direction of the tractor 12. By fixing the stirring device 22 at such a position, the stirring device 22 can be fixed well without interfering with other devices. Further, the stirring device 22 is preferably fixed near the bottom surface of the liquid tank 18. This is because even if a relatively small amount of liquid is carried into the liquid tank 18, the liquid in the liquid tank 18 can be reliably stirred.

  For example, in the present embodiment, the outer wall (side wall) of the liquid tank 18 is provided with a protruding tube 23 that protrudes in a substantially horizontal direction, and the stirring device 22 is disposed in the protruding tube 23 and It is being fixed to the flange part 24 provided in the front-end | tip by fastening members (not shown), such as a screw. A plurality, for example, four ribs 25 are provided on the outer peripheral surface of the protruding tube 23 to ensure the strength of the protruding tube 23. In this way, it is preferable that at least the lower end portion 23a of the inner surface of the protruding tube 23 in which the stirring device 22 is installed is inclined so as to be lowered toward the liquid tank 18 side. Thereby, it is possible to prevent the liquid from accumulating in the protruding tube 23.

  Here, the stirring device 22 according to the present embodiment is not particularly limited as long as the liquid in the liquid tank 18 can be stirred. For example, in the present embodiment, as shown in FIG. 3, the liquid is stirred. The impeller 26 is a stirring blade, and this impeller 26 is fixed to a rotary shaft 28 of a rotary drive means 27 such as an electric motor. That is, the agitation device 22 of this embodiment agitates two types of liquid in the liquid tank 18 by rotating the impeller 26 fixed to the rotation shaft 28 by the rotation driving means 27. And by stirring the liquid in the liquid tank 18 with the stirring apparatus 22 in this way, it becomes a chemical which is a mixed liquid of a plurality of types of liquids.

  The rotation driving means 27 of the stirring device 22 may be driven by receiving power supply from the user, for example, but may be driven by other methods. For example, a generator may be operated using the engine 11 of the tractor 12 as a power source, and the rotational driving means 27 may be driven by electric power from the generator. Further, the power source of the agitator 22 is not limited to the rotation driving means 27 that is an electric motor, and for example, the engine 11 of the tractor 12 may be used as a power source in the same manner as the rotary pump 20.

  In the liquid transfer and supply method according to the present embodiment, such a liquid transfer vehicle 10 is used to transfer a plurality of types of chemical raw materials, that is, two types of liquid in the present embodiment, to a user (customer). At the same time, these two types of liquids are finally supplied to the user as chemicals. Specifically, two types of liquids that are raw materials for chemicals are carried into the liquid tank 18 of the liquid transfer vehicle 10 and conveyed to the use destination.
