Description

TECHNICAL FIELD

[0001] The utility model relates to calcium carbonate measuring equipment field, especially in soil calcium carbonate content's determination device. BACKGROUND

[0002] The method for measuring the calcium carbonate content in the soil in the prior art is to add the soil into a reaction bottle, then place a finger-shaped tube in the reaction bottle, add an acidic solution (generally hydrochloric acid) into the finger-shaped tube, then seal the reaction bottle with a sealing plug, open an air hole on the sealing plug, and seal a rubber tube on the air hole, and the rubber tube is connected to a measuring instrument. During the test, the tester needs to tilt the reaction bottle to mix the acidic solution in the finger-shaped tube with the soil to cause a chemical reaction. If a full reaction is needed, the soil in the reaction bottle needs to be stirred. The general operation mode is that the operator manually shakes the reaction bottle. During the shaking process, the finger-shaped tube and the reaction bottle are prone to collision, which may cause damage to the reaction bottle or the finger-shaped tube. This not only causes damage to the equipment, but also easily causes injury to the operator. If the reaction bottle is broken, the acidic solution may splash on the operator, which may cause injury. The broken finger-shaped tube or reaction bottle may easily scratch the operator. Meanwhile, the rubber tube connected to the reaction bottle may be disturbed during the tilting and shaking of the reaction bottle, which may cause a false increase in the measurement volume and cause measurement errors. At the same time, the final determination of the gas volume is manually searching for a horizontal line, which is time-consuming and laborious. Therefore, there is an urgent need for a determination device to simplify the experimental process and improve the safety, accuracy, and efficiency of the experiment. SUMMARY
