And.

  The storage unit 62 includes, as the above various parameters, the calcium content Cca of the cement to be measured, the specific gravity (≈unit volume weight) SGc of the cement, and the weight W1 of the spiral metering tube 32 when the solution is empty. The volume Vo of the spiral measuring tube 32 is stored.

  FIGS. 8A and 8B are flowcharts for explaining a solution analysis method using the solution analyzer 10. In the solution analyzer 10, a fixed amount solution is circulated at a constant speed in the circulation line 20 for a predetermined time T, and during the predetermined time T, the weight W2 is measured by the weight measuring device 30 and the fluorescent X-ray measuring device. The measurement of the calcium content Pca by 50 is carried out continuously.

The calculating unit 66 calculates the unit volume weight UW0 of the solution according to the following equation (1) (step 1). Here, W2 is the total weight of the spiral metering tube 32 and the solution therein, and is a value obtained by averaging a large number of measured values of the weight W2 obtained during the predetermined time T. W1 is the weight of the spiral metering tube 32 when the solution is empty as described above, and Vo is the volume of the spiral metering tube 32 as described above.
UW0 = (W2-W1) / Vo (1)

The calculation unit 66 calculates the cement content Pc of the solution according to the following equation (2), and calculates the weight Wc of the cement in the solution having the volume V0 according to the following equation (3) (steps 2 and 3). Here, Pca is a value obtained by averaging a large number of measured values of the calcium content Pca of the solution obtained during the predetermined time T. Cca is the calcium content of the cement as described above.
Pc = Pca / Cca (2)
Wc = UW0 × Pc (3)

The calculating unit 66 calculates the volume Vc of the cement in the solution having the volume V0 according to the following equation (4) (step 4). Here, as described above, SGc is the specific gravity of the cement and is an approximate value of the unit volume weight of the cement.
Vc = Wc / SGc (4)

In addition, the calculation unit 66 calculates the volume Vws and the weight Wws other than cement (water containing earth and sand) in the volume V0 solution according to the following equations (5) and (6) (steps 5 and 6). Here, Vo is the volume in the spiral metering tube 32 as described above, that is, the volume of the solution in the spiral metering tube 32.
Vws = Vo-Vc (5)
Wws = UW0−Wc (6)

Moreover, the calculating part 66 calculates the unit volume weight (≒ specific gravity) UWws of the water containing the earth and sand in a solution by the following (7) Formula (step 7).
UWws = Wws / Vws (7)

  From the above, the cement content Pc of the solution and the unit volume weight (≈specific gravity) UWws of the water containing earth and sand in the solution can be obtained.

Next, processing and calculation methods by the operator will be described. As shown in the flowchart of FIG. 8 (B), first, a unit volume of the solution is taken out from the circulation pipe 20 and put in a drying device (not shown) and dried, and the weight Wcs between the cement and the earth and sand after drying is not determined. Measurement is performed with the illustrated weight measuring apparatus (step 11). Next, the weight Ws of the earth and sand and the weight Ww of the water are calculated by the following formula (8) and the following formula (9) (step 12). Here, Wc is the weight of the cement calculated by the above formula (3), and Wws is the weight of water containing earth and sand in the solution calculated by the above formula (6).
Ws = Wcs−Wc (8)
Ww = Wws-Ws (9)
As described above, the weight ratio (Wc: Ws: Ww) of cement, earth and sand, and water in the solution can be obtained.

  Here, in the solution analyzer 10 according to the present embodiment, the weight of the spiral measuring tube 32 is measured by the load cell 38 while flowing the solution through the circulation pipe 20, and the solution in the tube is measured by the fluorescent X-ray measuring device 50. The calcium content of is measured. As a result, the solution analyzer 10 can repeatedly measure the weight of the spiral metering tube 32 and the calcium content of the solution while the solution is flowing in the circulation line 20. Thereby, a large number of measurement data for obtaining the unit volume weight UW0 of the solution and the cement content Pc can be collected, and the accuracy of analysis of the solution can be improved.

  In the solution analyzer 10 according to the present embodiment, the fluorescent X-ray measurement device 50 is arranged on the upper side of the X-ray measurement block 40, and the X-ray transmission film 46 is an X-ray projection port of the fluorescent X-ray measurement device 50. The fluorescent X-ray measurement device 50 measures the calcium content of the solution in the X-ray measurement block 40 through the X-ray transmission film 46. Thereby, when a solution leaks in the X-ray measurement block 40, it is possible to prevent the solution from being applied to the fluorescent X-ray measurement device 50. In such a case, it is possible to prevent the fluorescent X-ray measurement device from failing.

  Here, since the specific gravity of cement is larger than that of water, cement is precipitated in the solution. For this reason, the larger the longitudinal diameter in the X-ray irradiation region in the X-ray measurement block 40, the higher the cement concentration on the bottom side in the X-ray irradiation region, while the lower the cement concentration on the upper side in the X-ray irradiation region. . Therefore, the cement concentration in the X-ray irradiation region becomes non-uniform, and the calcium content of the solution cannot be accurately measured.

  On the other hand, in the solution analyzer 10 according to the present embodiment, the vertical diameter of the flow path 41 in the X-ray measurement block 40 is set to be smaller than the upstream side and the downstream side at the X-ray irradiation point. (See FIGS. 3 and 4A to 4C). Thereby, the uniformity of the density | concentration of the cement in a X-ray irradiation area | region can be improved, and the measurement precision of the calcium content rate of a solution can be improved.

  Moreover, since the horizontal diameter of the flow path 41 in the X-ray irradiation area is set wider than the inner diameter of the pipes 20A to 20D of the circulation path 20, it is possible to suppress a decrease in the flow path cross-sectional area in the X-ray irradiation area. . Therefore, an increase in the flow rate of the solution in the X-ray irradiation region can be suppressed, and an increase in the fluid pressure acting on the X-ray permeable membrane 46 can be suppressed.

  Moreover, when the distance between the X-ray projection port of the fluorescent X-ray measurement apparatus 50 and the liquid surface of the solution is not constant, the measurement accuracy of the calcium content of the solution is lowered. On the other hand, in the solution analyzer 10 according to the present embodiment, since the liquid level of the solution in the X-ray irradiation region can be maintained at the height of the X-ray permeable membrane 46, the calcium content of the solution Measurement accuracy can be improved.

  In the solution analyzer 10 according to this embodiment, the solution is circulated in the circulation path 20. Thereby, more measurement data for obtaining the unit volume weight of the solution and the cement content can be collected, and the accuracy of analysis of the solution can be further improved. Moreover, by forming a circulation flow of the solution in the circulation path 20 and stirring the solution, cement precipitation in the solution can be suppressed, and the measurement accuracy of the calcium content of the solution can be improved.

  In the solution analyzer 10 according to the present embodiment, the upstream end and the downstream end of the spiral metering pipe 32 are connected to the pipe 20A by the flexible pipe 34U and to the pipe 20B by the flexible pipe 34L, respectively. Thereby, the spiral measuring tube 32 is configured to be able to be suspended independently from the piping 20A and the piping 20B, and the suspended weight of the spiral measuring tube 32 having a predetermined volume can be measured.

  In addition, since the spiral metering pipe 32 is a spiral pipe, the solution weight measurement section can be extended while suppressing the expansion of the installation space of the pipe. Therefore, the measurement accuracy of the unit volume weight of the solution can be improved while suppressing the increase in size of the solution analyzer 10.

  In the solution analyzer 10 according to the present embodiment, the storage unit 62 stores the weight W1 of the spiral metering tube 32 and the volume V0 of the spiral metering tube 32 when the solution is empty. 66 calculates a unit volume weight UW0 of the solution based on the weight W1 and volume V0 stored in the storage unit 62 and the weight W2 of the spiral metering tube 32 measured by the load cell 38.

  The storage unit 62 stores the calcium content Cca of cement contained in the solution to be measured, and the calculation unit 66 uses the calculated unit volume weight UW0 of the solution and the fluorescent X-ray measurement device 50. Based on the measured calcium content Pca of the solution, the cement content Pc of the solution is calculated. Thereby, the weight Wc and the volume Vc of the cement in the solution of the volume V0, the components other than the cement in the solution of the volume V0, that is, the weight Wws and the volume Vws of water including earth and sand can be obtained.

  Further, the calculation unit 66 calculates the unit volume weight (≈specific gravity) UWws of the water other than the cement of the solution, that is, the water containing earth and sand, based on the calculated unit volume weight UW0 of the solution and the cement content rate Pc of the solution. To do. Here, when reusing the surplus suspension, the components of the suspension become a problem. According to the analysis described so far, if the cement content Pc is reduced, the cement is added and adjusted so that the content becomes the design blend value.

  The unit volume weight UWws of water containing earth and sand is the unit volume weight 1.0 of water plus the unit volume weight of earth and sand. In such a case, filter processing will be applied to reduce sediment. Then, when it is desired to accurately grasp the weight of earth and sand that is actually a problem, the flow of FIG.

  In the present embodiment, the solution is circulated through the circulation line 20, but it is not essential. The solution may be passed through the spiral metering tube 32 and the X-ray measurement block 40 only once. For example, the spiral metering tube 32 and the X-ray measurement block 40 may be provided in a branch pipe that branches off from the main pipe through which the solution flows in one direction and returns to the main pipe.

  In the present embodiment, the processing by the calculation device 60 ends with the calculation of the unit volume weight UWws of the water including the earth and sand in the solution, but may continue until the calculation of the respective contents of the earth and water of the solution. Good. In this case, the specific gravity of the earth and sand is stored in the storage unit 62, and based on the specific gravity of the earth and sand, the unit volume weight (≈ specific gravity) UWws of the water containing the earth and sand in the solution, the unit volume weight UW0 of the solution, and the like. By calculating the respective weights of the soil and water of the solution of volume V0, the respective contents of the soil and water of the solution can be obtained.

  In the present embodiment, the surplus suspension generated by the ultra-high pressure jet method is used as a solution to be analyzed. However, any solution containing cement can be a solution to be analyzed by the solution analyzer of the present invention. Moreover, although the fluorescent X-ray measuring apparatus 50 was used as an apparatus for measuring the calcium content of the solution, other component measuring apparatuses capable of measuring the calcium content may be used.
