Conventional quicklime trucks have a loading capacity of 10 to 15 tons, and multiple trucks are required to transport quicklime to factories that use large amounts of quicklime, such as steel mills. Therefore, there is a problem that the transportation cost becomes high.
In order to reduce the transportation cost of quicklime, it is effective to store quicklime in a container and transport it using a vehicle or a ship. However, until now, no attempt has been made to transport hygroscopic solids such as quicklime using a large-capacity container.

  Accordingly, an object of the present invention is to provide a container that can be advantageously used for mass transportation of hygroscopic solids using vehicles and ships. Another object of the present invention is to provide a method for transporting quicklime using the container.

  The present invention is a rectangular parallelepiped vehicle having a length in the width direction of 2 to 4 m, a length in the front-rear direction of more than twice the length in the width direction, and a height of 2 to 4 m. Alternatively, on the upper surface of the vessel-mounted container, it is provided with two or more hygroscopic solid material inlets arranged in the front and rear with an interval of 1/4 or more and 3/4 or less of the length in the longitudinal direction of the container, And it exists in the hygroscopic solid substance conveyance container provided with the hygroscopic solid substance discharge port in the front surface or the rear surface.

The preferable aspect of the container for hygroscopic solids conveyance of this invention is shown below.
(1) The hygroscopic solid material inlet has two front inlets and a rear inlet, and the front inlet is at least 1/6 of the length in the front-rear direction of the container when viewed from the front. The rear inlet is at a position that is 1/6 or more of the length of the container in the front-rear direction when viewed from the rear.
(2) The hygroscopic solid material discharge port is provided so that the lower part of the front surface or the rear surface of the container opens outwardly.
(3) At least the bottom and both side surfaces of the container are corrugated steel plates, and the inner side of the bottom surface and both side surfaces is lined with a plate having a smooth inner surface.

  This invention also exists in the quicklime transport method which accommodates and transports quick lime in said hygroscopic solid substance conveyance container.

The container of the present invention has a length in the width direction of 2 to 4 m, a length in the front-rear direction is more than twice the length in the width direction, and a height of 2 to 4 m. Larger than the truck's quicklime storage tank. Further, in the container of the present invention, two or more hygroscopic solid material inlets are arranged at the front and rear with an interval of 1/4 or more and 3/4 or less of the length in the front-rear direction of the container, The hygroscopic solids charged from the respective hygroscopic solid material inlets accumulate in a form in which the mountains and mountains are continuous inside the container. For this reason, since the container of the present invention has a smaller dead space inside the container than in the case where there is only one hygroscopic solid material inlet, the accommodation efficiency of the hygroscopic solid material is increased. Furthermore, in the container of the present invention, since the opening area of the hygroscopic solid material inlet can be reduced as compared with the quick lime inlet of the conventional quicklime transport truck, moisture hardly enters the container. Therefore, the container of the present invention can be advantageously used for mass transportation of hygroscopic solids using vehicles and ships.
Moreover, according to the quick lime transportation method of the present invention in which quick lime is accommodated and transported in the hygroscopic solid material transport container, a large amount of quick lime can be transported at low cost.
