Heated air circulation drying kiln for non-dismantling heat insulation formworks

Abstract

The invention discloses a heated air circulation drying kiln for non-dismantling heat insulation formworks. The heated air circulation drying kiln comprises a kiln body. At least two layers of carrier rollers are mounted in the kiln body. The carrier rollers are mounted horizontally and are perpendicular to the kiln body. The carrier rollers are equidistantly mounted from one end of the kiln body to the other end of the kiln body. The distance between each upper carrier roller and the corresponding lower carrier roller is larger than the thickness of the non-dismantling heat insulation formworks. The carrier rollers are driven by motors. The top of the kiln body is provided with a heated air inlet and a waste air outlet. A natural gas heater is connected to the heated air inlet. A natural gas pipeline and an air oxygen supply pipeline are connected to the natural gas heater. A circulating fan is mounted on the natural gas heater. A heat exchanger is connected to the waste air outlet. An air inlet fan is connected to an air inlet of the heat exchanger. An air outlet of the heat exchanger is connected with the air oxygen supply pipeline. A waste air discharge outlet of the heat exchanger is connected with a chimney. According to the heated air circulation drying kiln, the non-dismantling heat insulation formworks are conveyed through the carrier rollers; the drying effect is good; the drying efficiency is improved through the multiple layers of carrier rollers; and the heat exchanger increases the utilization rate of heat through natural gas burning drying.

Description

technical field [0001] The invention relates to the construction field, in particular to a hot air circulation drying kiln without dismantling the heat preservation formwork. Background technique [0002] The construction industry occupies a large proportion in the national economy. The development of construction technology plays a very significant role in saving energy, reducing energy consumption, and improving efficiency. Building energy conservation, reducing pollution, and reducing environmental load have become the challenges faced by the construction industry all over the world. major issues. [0003] Since the 1990s, many developed countries and regions have been committed to the development of a variety of new building systems, including Italy, France, Australia and my country's Taiwan have developed construction technology without demolition formwork, and have been partially applied, in my country This technology has just started in China.

[0003] Since the 1990s, many developed countries and regions have been committed to the development of a variety of new building systems, including Italy, France, Australia and my country's Taiwan have developed construction technology without demolition formwork, and have been partially applied, in my country This technology has just started in China. In the production process of the non-dismantling formwork, it is necessary to dry the non-dismantling formwork. The ordinary drying device has complex structure, poor drying effect, low work efficiency, and great environmental pollution.
