Novel intelligent automatic humidity and temperature kiln inside curing system and method for cement product

Abstract

The invention provides a novel intelligent automatic humidity and temperature kiln inside curing system for a cement product. The system comprises a curing kiln; four heat-insulation soft spaced sections are arranged in a sealed kiln body and correspond to four curing periods of the cement product respectively; and the four curing periods include a pre-curing period, a heating period, a heat preservation period and a cooling period. The method comprises the following concrete steps: 1) determining the time of the four curing periods, setting the conveying speed of a plate conveying chain belt to be a constant value, and enabling the curing time ratio of the four heat-insulation soft spaced sections to be equal to the length ratio of the four heat-insulation soft spaced sections; and 2) setting the temperature and the humidity in each of the four heat-insulation soft spaced sections through a steam humidification device and a warm wind temperature control machine respectively. According to the curing system and method, the hydration and carbonization processes of the concrete cement product can be accelerated, the curing cycle can be shortened, and the problem of quality influence due to a series of factors such as cracking, deformation, collapse and the like can be solved.

Description

technical field [0001] The invention relates to a novel intelligent automatic cement product curing system in a wet-heat kiln and a curing method thereof. Background technique [0002] The key to the factory automatic production line of lightweight concrete hollow building slabs is to solve the hydration and carbonation process of cement products within 12 to 16 hours, so that the hydration and carbonation strength can reach more than 50% to 70%, so as to meet the handling and packaging of cement products The work intensity in the process can realize the assembly line operation. [0003] In the prior art, people usually use heating to accelerate the solidification of concrete products, and the process of hydration and curing of cement products is an extremely complicated process. Different time and different temperature and humidity are the key to the curing of cement products If not well grasped, it will affect the quality of cement products, so that there will be cracks, ...

Problems solved by technology

Due to the low temperature in northern areas, people often use boilers for heating, but this method has two disadvantages: one is high cost; Enterprises can only choose to produce in warm summer and shut down in cold weather. They can only produce for about 6 months a year, and shut down for nearly half a year, which eventually leads to high costs, poor returns, and long investment recovery time.
