Description

Technical Field

[0001] The present invention relates to the technical field of road and bridge steaming, and in particular to a heat recovery system based on intelligent road and bridge steaming and a use method thereof. Background Art

[0002] With the rapid development of roads and bridges in my country, the demand for high-quality roads and bridges is increasing day by day, which puts higher requirements on the quality and production efficiency of roads and bridges. In actual production, the production cycle of roads and bridges is shortened mainly by steam curing them. The specific operation is to directly place the roads and bridges in a curing kiln filled with steam to speed up the solidification of concrete, so that the newly cast roads and bridges can meet the requirements of engineering use in a short time, greatly reducing the production period of roads and bridges. Therefore, steam curing is the key to ensuring the quality of roads and bridges and improving production efficiency.

[0003] After searching, it is found that the patent with patent publication number CN217777296U discloses a large-volume steaming kiln, including a steaming kiln main body, a steam system and a material inlet and outlet assembly. The steam system is arranged inside the steaming kiln main body, and the material inlet and outlet assembly is arranged inside the steaming kiln main body for inputting or outputting steamed materials into or out of the steaming kiln main body. The material inlet and outlet assembly includes two sets of traveling tracks arranged along the length direction of the steaming kiln main body and a crane erected above the two sets of traveling tracks. Track grooves are opened on the upper surface of the traveling tracks along the length direction. Traveling wheels are installed at the bottom of the crane, and the traveling wheels are rollingly connected to the track grooves. A driving assembly for driving the crane to move is also installed inside the steaming kiln main body. The utility model is suitable for the steaming kiln, and the materials are steamed by the material inlet and outlet assembly, so that the steaming process of the materials occurs in the crane, which can prevent the debris generated by the steamed materials from falling into the steaming kiln main body, and ensure that the secondary use of the steaming kiln will not be affected when the materials are steamed.
