Concrete steam curing box

Abstract

The invention discloses a concrete steam curing box comprising a test piece box and a steam delivery device. The steam delivery device comprises a heating water tank and a water supply device. The heating water tank is connected with the test piece box through a first pipeline. The water supply device comprises a water supply unit and a water supply box. The water supply unit is connected with the water supply box through a second pipeline. A water level switch is disposed inside the water supply box. The water supply box is connected with the heating water tank through a U-shaped pipe. Two ends of the U-shaped pipe are connected with the bottom of the water supply box and the bottom of the heating water tank. The water supply box in the steam delivery device is connected with the heating water tank through the U-shaped pipe, the U-shaped pipe prevents boiling water in the heating water tank from reflowing to the water supply box through a liquid seal, the water level switch is protected from heat damage, dry heating of the heating water box can also be prevented, and damage of the heating water tank is avoided.

Description

technical field [0001] The invention relates to a steam curing box, in particular to a concrete steam curing box. Background technique [0002] The concrete steam curing box is a special equipment for simulating the steam curing environment of concrete specimens. At present, the commonly used concrete steam curing box is generally used to add water to the heating water tank, the heating water tank heats the water, and then steam is input into the test piece box through pipelines to perform steam curing on the concrete test piece. When curing the test piece, the water in the heating water tank of the concrete steam curing box should be supplemented at any time as needed. [0003] At present, a water replenishment device is usually used to replenish water to the heating water tank. The water replenishment device includes a water replenishment box, a water supply device, and a pipeline connecting the water replenishment box and the water supply device. When the water replenis...

AI Technical Summary

Problems solved by technology

When the water supply device supplies water to the heating water tank, the boiling water in the heating water tank will often flow back into the water supply box, causing the temperature of the water in the water supply box to rise, thus causing the water level switch in the water supply box to be damaged due to heat

[0004] Such as the Chinese invention patent "Concrete Steam Curing Box", the application number is 201220745763.5, which discloses a concrete steam curing box, which is provided with a one-way valve between the water supply box and the heating water tank. The boiling water in the hot water tank returns to the water replenishment box, thereby avoiding the damage of the water level switch due to heat. However, the boiling water flowing back in the hot water tank will block the one-way valve, so that the water replenishment box cannot replenish water into the heating water tank, causing the heating water tank to dry. resulting in damage to the heating tank
