Concrete sleeper curing cooling system and curing cooling method

Abstract

The invention relates to a concrete sleeper maintaining and cooling system and a maintaining and cooling method. The concrete sleeper maintaining and cooling system comprises at least two maintaining pits. One sides of the maintaining pits are provided with air blowers. Air outlets of the air blowers are communicated with the bottoms of the maintaining pits through air inlet pipes. The pit tops of the other sides of the maintaining pits are communicated with the air inlet end of an air outlet pipe. An axial flow fan is arranged on the air outlet pipe and the air outlet end of the air outlet pipe is communicated with the first interface of a tee joint. The second interface of the tee joint is communicated with a trench through an air exhaust pipe and the third interface of the tee joint is communicated with the bottoms of other maintaining pits through an air returning pipe. Ball valves are arranged on the air exhaust pipe and the air returning pipe. The air blower and the axial flow fan are communicated with a computer temperature control device. The concrete sleeper maintaining and cooling system and the maintaining and cooling method have the advantages of being obvious in cooling effect and ideal in temperature reducing curve and can improve the inherent quality of a sleeper. Steam can be utilized in a circulating mode as the pits are connected in series through the pipelines. The purposes of reducing the steam consumption amount of a single product and utilizing energy to the maximum are achieved.

Description

technical field [0001] The invention relates to the field of prestressed concrete pillow production, in particular to a system and method for steam curing and cooling of prestressed concrete pillows. Background technique [0002] In the production of sleepers by the flow method of the unit, the maintenance pit is generally used for steam maintenance of the sleeper. Among them, cooling is one of the key links in the maintenance process, because the cooling gradient of the sleeper per hour during the cooling process cannot be greater than 15 degrees. It can not be higher than 15 degrees. Too fast cooling will affect the quality of the sleeper, which does not meet the requirements of the process. Too slow cooling will affect the production progress and reduce labor productivity. Therefore, manufacturers across the country have been deeply exploring how to control the cooling of sleepers. At present, whether it is water cooling or exhaust cooling, the effect is not very satisfac...
