[0002] Shield slag is the slag produced during the shield construction process. In order to avoid the pollution caused by shield slag to the construction, a dehydration and drying device is usually used to dehydrate and dry the shield slag, and the dehydrated and dried shield slag is transported to other places.

[0003] For example, a drying system for dehydration of shield slag with application number 202023301379.X includes a box body, and slots are provided in the middle of both sides of the box body, and the upper ends of the slots are in a through state. A plurality of threaded grooves are provided at equal intervals on the lower end of the inner part of the box body, and the plurality of threaded grooves are all in an annular structure.

A plurality of protective sleeves are evenly spaced and slidably connected to the placement plate. The number of protective sleeves is the same as the number of threaded grooves and corresponds one to one. The beneficial effect of the utility model is as follows: the utility model provides a cavity with a heating plate installed at the lower end of the inner part of the box body, and a plurality of heat-conducting rods are installed on the heating plate. During drying, the plurality of heat-conducting rods are inserted into the inside of the shield slag, so that during heating, heat is dissipated from the inside to the outside to various parts of the shield slag, and the heat conduction speed is faster, thereby shortening the drying time of the shield slag.
