生ガス量の測定方法および測定装置に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention measures the volume of the introduced gas by introducing a gas into a liquid and replacing the same volume of liquid with the introduced gas. For example, in order to control the process by predicting the amount of gas generated from core molding sand that adjusts the inner shape when casting a casting, the gas generated by heating a core molding sand sample is used. The present invention relates to a method and apparatus for measuring the amount of gas generated from an object to be measured.

目になっている。Foundry sand called coated sand is often used as the foundry sand for the core. Coated sand is made by adding about 2% to 3% by weight of phenol resin as a binder to silica sand. Some contain a small amount of hexamethylenetetramine as a curing accelerator. These additives decompose and produce gas when heated. However, if the amount of gas generated during mold casting is too large, it will interfere with the design of the mold, so it is necessary to predict the amount of gas generated in advance. In particular, when repeatedly used as recycled foundry sand, the amount of gas generated varies greatly, so predicting the amount of gas generated is an important control item in order to adjust this to within a control range.

It is placed on top. When water droplets drip, if you leave them as they are, the pressure in the sealed space will increase, and the water head corresponding to the water depth in the separating funnel will become small (so that when the negative pressure and the water head become equal, the 11 reaches equilibrium and water drops stop dripping.This state is taken as the state to start measurement.In this way, the object to be measured is inserted into the combustion section of the siliconint furnace (3), which is heated, and the temperature is increased. When gas is generated from the child foundry sand sample, the same volume of water as the generated gas is removed from the separatory funnel and dripped into the graduated cylinder, and its weight is automatically measured and recorded on a computer. - (- In the case mentioned above, the number of grams of the measured weight becomes the number of generated gases C and C. With this configuration, for example, when the sample is heated to 1200C,
The amount of gas generated can be accurately measured and recorded in real time.

The amount of change is equal to the change in force applied to the leveler (14) as a reaction. The volume of the liquid is determined by dividing the amount of change in the force applied to the measuring device (14) by the specific gravity of the liquid, and the volume of the collected gas generated that is equal to this volume can be determined.

Collect the generated gas from the object to be measured, introduce the recovered gas into the fixed space by replacing it with the liquid contained in the fixed space, and by the replacement, the generated gas will be introduced into the fixed space. A method for measuring the amount of gas generated from an object to be measured, in which the weight of the liquid removed from the object is measured, and the measurement result is converted into volume to determine the volume of the gas generated. 2. A gas recovery section for recovering generated gas from the object to be measured is provided, and a liquid storage space (S) is provided in which a liquid is stored in advance and the generated gas recovered by the recovery section is introduced to replace the stored liquid. a gas-liquid displacement section, a measurement section that measures the weight of the liquid removed from the liquid storage space by replacement with the generated gas, and a calculation section that converts the measurement result by the measurement section into a volume. A device for measuring the amount of gas generated from objects. 3. To configure the gas-liquid replacement section, a closed container forming the liquid storage space (S) is provided inside, a connection port for the gas recovery section is provided in the upper part of the closed container, and a connection port for the generated gas is provided in the lower part. 3. The apparatus for measuring the amount of gas generated from the object to be measured according to claim 2, further comprising a discharge port for the liquid to be removed by replacing the liquid with the liquid. 4. The gas-liquid exchange section is configured by a first tube whose upper part is sealed.
A space (S1) and a second space (S2) with an open top are provided, both spaces are communicated at the bottom to form the liquid storage space (S), and a connection to the gas recovery section is provided at the top of the first space. 3. The apparatus for measuring the amount of gas generated from an object to be measured according to claim 2, further comprising an opening, and a discharge port provided above the second space for overflowing the liquid removed by replacement with the generated gas. 5. Collect the generated gas from the object to be measured, introduce the recovered generated gas into the liquid, measure the buoyancy of the gas in the liquid, and calculate the weight of the liquid with the same volume as the gas from the buoyancy measurement result. A method for measuring the amount of gas generated from an object to be measured, in which the weight is determined, the weight is converted into the volume of a liquid, and the volume of the gas generated is determined from the converted volume.
