Structure and working principle of concrete accelerated curing box
. Concrete accelerated curing box is composed of curing part and control box.
) The maintenance department consists of the box cover, outer shell, stainless steel liner, box feet, etc. The space between the outer shell and the inner tank is filled with high-efficiency insulation boards for insulation, and several channel steels are used between the bottoms to carry the load of all specimens. A water sealing groove is designed along the edge of the curing box, and four immersed steel pipes are installed in the inner tank of the curing box. Type heating tubes (their arrangement is that the first, third, and fourth heating tubes from the right side of the curing box are all heating tubes, and the second heating tube is ). There are injection and drain ports at the bottom of the inner tank of the curing box.
b) The control box is equipped with a complete set of control instruments, electrical and all heating tube terminals.
. Working Principle
When restoring the test set water temperature after heating the curing water or placing the test piece, the four heating tubes are energized at the same time. When the required test set water temperature is reached or the test setting is restored After the temperature is reached, manually turn the heating and heat preservation switch to switch from the heating state to the heat preservation state. In the heat preservation state, only one heating tube is working (the maintenance and heat preservation time is set by the user, just turn the digital display The time relay dial can set the maintenance time). After the holding time is up, the alarm buzzer sounds to prompt the tester to turn off the power and take out the test piece.
4. Concrete accelerated curing box. Instructions for use
. Water injection: Open the lid of the box and pour water into the box. When the water surface is about 30 meters away from the edge of the box, stop filling (while filling water, the mouth of the box edge seals the groove (should also be filled with water), cover the box cover, pull out the temperature probe from the temperature measuring component socket on the right control box and insert it into the temperature measuring component socket of the box cover.
.Heating: Set the required curing water temperature value on the temperature control instrument, turn on the power switch, and the curing water starts to heat up.
Note: The switch of the curing water from the heating state to the heat preservation state must be performed by the tester by flipping the heating and heat preservation switch, so the tester please pay attention!
When the temperature of the curing water in the box reaches the set temperature, turn off the power, pull out the temperature measuring probe, face the front of the curing box and slowly open the lid. After removing the lid, use a special tool hook to Place the test pieces one by one on the water shelf (please leave the temperature probe position open when placing the test pieces). After placing the test piece, close the lid, plug in the temperature probe, and turn on the power. The water temperature will quickly return to the set temperature. (When the temperature of the curing water rises to ℃, due to the boiling of the water in the box, the boiling water may overflow in a short period of time. It will return to normal after entering the heat preservation state).
.Insulation: On the insulation time control instrument on the control panel, set the required insulation time (in minutes), turn the insulation heating switch to the insulation state, press the timing button, and the maintenance will enter the insulation state. When the heat preservation time is up, a buzzer alarm will sound in the control box, reminding the operator that the maintenance is completed and the power can be turned off.
5. Precautions for concrete accelerated curing box
Do not place the lid of the accelerated curing box upside down during use (you can refer to the position of the prompt sign on the lid to see it facing up).
.When placing the test piece, the corresponding position of the temperature measurement probe should be left to avoid damage to the probe when inserted.
.Safety must be paid attention to when putting in and taking out the test piece. That is, when using a special tool to hook the test piece, it is necessary to confirm whether the tool hook has firmly hooked the test piece to prevent the test piece from falling out of the box during the operation. Hot water splashing inside can hurt people.
.After using the accelerated curing box, the power must be cut off to prevent the electric heating tube from being inadvertently heated, causing dehydration and damage to the machine.
. When the accelerated curing box is not used for a long time, the water must be drained and dried, and placed in a ventilated and dry place.
