Prefabricated concrete member steam curing production line and steam curing method

Abstract

The invention discloses a prefabricated concrete member steam curing production line and a steam curing method. The production line is composed of a steam heat source machine system, a steam transmission pipeline, a mold table and a steam curing shed, wherein water is converted into dry steam through the steam heat source machine, the dry steam is distributed to all pipelines through a steam distributing cylinder and finally enters the steam curing shed of a production line, valves on the steam transmission pipeline independently control mold table sets, temperature and humidity control is conducted through the steam curing shed and a temperature and humidity sensing probe, temperature control in a curing process is divided into temperature rise and then natural cooling, the heat preservation time of each stage is strictly controlled, and finally it is ensured that the strength of a component meets the specified requirement after the natural cooling. The prefabricated concrete member steam curing production line and the steam curing method are energy-saving, consumption-reducing, emission-reducing and efficiency-improving, the construction cost is low, the occupied area is small, the site utilization rate is high, the operation flexibility is high, the curing effect is good, the mold stripping time is shortened, the mold stripping strength is improved, the production efficiencyis improved, the component surface is crack-free, and the heat energy utilization rate is high.

Description

technical field [0001] The invention relates to a prefabricated concrete component steam curing production line and a steam curing method, belonging to the technical field of prefabricated concrete component maintenance. Background technique [0002] The traditional steam curing production line for precast concrete components consists of a mold table, a transmission pulley and a steam curing kiln. After the workers have finished binding the steel bars, they are transported forward to the vibrating table through the pulleys for pouring and vibration. If the efficiency of one link is too slow, the follow-up link Workers will not be able to continue working, greatly reducing work efficiency. When pouring concrete, only one slab can be poured at the same time, and the vibrating table can only vibrate one mold table at the same time. After that, it is sent to the steam curing kiln for curing, and after the curing is completed, it is sent to the board outlet for loading. Therefo...

AI Technical Summary

Problems solved by technology

Therefore, the traditional steam curing production line of precast concrete components needs to purchase a large amount of equipment, which is expensive and takes up a lot of space, but the number of molds that can be produced at the same time is small, and the site utilization rate is low

Production can only be carried out according to the process. Once there is a problem with the middle transmission pulley and the mold table cannot continue to be transported forward, the subsequent mold table production will be affected and accidents will easily occur

During the maintenance process of prefabricated concrete components, heat will be generated inside, which will easily cause the internal temperature to be too high and damage the internal structure, so that its overall strength cannot meet the requirements, and the appearance is also prone to cracks, making the actual strength lower than the design strength.

Moreover, the traditional boiler is a special equipment that needs to be submitted for approval for annual inspection; the initial heating time is 20~40 minutes; the softened water system is prone to fouling, and the thermal efficiency is reduced; the internal material conductivity of the furnace body is low; ; Big potential safety hazard
