An air energy curing kiln

Abstract

The invention discloses an air energy curing kiln. The air energy curing kiln comprises a kiln body, a hot air pipe arranged in the air energy curing kiln and an air source high temperature heat pump constant temperature system used for providing a heat source for the interior of the air energy curing kiln, wherein the kiln body is formed by an external frame made of H-shaped steel and autoclaved lightweight concrete (ALC) plates, the interior of the air energy curing kiln is divided into a preheating zone, a heating zone, a constant temperature zone and a cooling zone, which are sequentially distributed, a double rail used for running of a curing dolly is laid on the ground in the air energy curing kiln, the hot air pipe comprises an air supply pipe arranged on the inner face of a wall of the air energy curing kiln and an air return pipe hung on the lower end face of a kiln crown of the air energy curing kiln, and the air source high temperature heat pump constant temperature system comprises a high temperature hot water machine unit, a pressure bearing water tank and a high temperature heat exchange air cabinet. According to the air energy curing kiln, a traditional steam and electric heating curing mode is changed, a dry heat curing method is used, a whole sealing measure is adopted, continuous curing is performed on a concrete prefabrication component, not only is intensity of the component enabled to meet design requirements, but also the air energy curing kiln guarantees that the surface of the component is smooth, and consistent in color, and does not comprise an air hole, a crack or leakage slurry, and furthermore high performance requirements of the air energy curing kiln are achieved.

Description

technical field [0001] The invention relates to a curing kiln for concrete components, in particular to an air energy curing kiln for concrete components. Background technique [0002] In the production process of concrete prefabricated components, heating curing is generally used in order to shorten the production cycle. The traditional curing kiln maintenance uses steam and electric heating to ensure the temperature and humidity of the curing. It is less affected by the weather, but it consumes a lot of energy and water. At the same time, the boiler used for heating produces a large amount of carbon dioxide, which is not conducive to energy conservation and environmental protection; and the traditional Heating maintenance, cumbersome management, it is difficult to ensure the temperature and humidity of prefabricated components during the maintenance process, which is very limited. [0003] In the process of factory production of concrete prefabricated components, the perf...
