である。 In turbine condensers, a so-called cleaning operation is also used to remove dirt from inside cooling pipes using sponge balls (hereinafter simply referred to as balls). It is known that these balls wear out during cleaning operations and their diameter decreases, eventually causing them to lose their cleaning effectiveness. For this reason, it is necessary to replace the worn balls with new ones, but a method is used in which the balls are taken out of the system and then sorted or counted using human labor. This takes a lot of effort. Also,
There is a method of sorting with a sieve and then counting using an optical method, but the sorting accuracy is low and counting is often impossible due to the influence of dirt, making it difficult to accurately grasp the recovery rate of balls. It is inappropriate for

うにしたものである。 The key point of the present invention is that since sponge balls have contractility, the size and number of balls are determined by detecting the amount of pressure received by means of generating surface pressure when the balls pass through a narrow channel. It is designed to let you judge.
本発明の実施例を図面に従い説明する。 Embodiments of the present invention will be described with reference to the drawings.

みを洗浄工程に戻すことが容易である。 FIG. 1 shows the configuration of the present invention, in which a pressure sensor 2 is provided on the wall surface of a channel 1 with the pressure receiving surface facing into the channel. The pressure sensor 2 may be a general thin plate-like sensor that can be detected as an electrical conversion quantity by a strain gauge or a semiconductor gauge due to its deformation. The signal from the sensor 2 is detected by the amplifying converter 5, the amount of electrical conversion when the ball passes the pressure receiving surface is processed, and the signal is led to the arithmetic processor 10 which can transmit counting and sorting outputs. Further, in FIG. 1, the internal dimension of the flow path in which the pressure sensor 2 is attached is made smaller than the diameter D B of the ball, so that the elastic force can be adjusted by the deformation of the ball applied to the pressure receiving surface when the ball passes. In other words, if the channel dimensions are kept constant, the output of the pressure sensor, that is, the peak value shown in Figure 3, will change depending on the size of the ball, and by setting the level, it is possible to distinguish between large and small ball diameters. It is possible to count the number of peaks that exceed the set value. Furthermore, the number of peaks smaller than the set value can also be counted at the same time. Therefore, by using the signal obtained by the sorting means according to the present invention, it is easy to control a distributor or the like that can discharge small balls out of the system, and return only normal balls to the cleaning process.

ある。 Next, based on the experimental data, the selection and
The counting means will be described. Figure 2 shows a ball diameter with a flow path diameter of 24φ and an average flow velocity of 1 m/s in the flow path.
The output of the pressure sensor when changing from 24φ to 30φ is converted and shown as the amount of pressure received. That is, when the horizontal axis represents the d/D B ratio, a curve is obtained in which the amount of pressure received increases as the size of the ball increases. In FIG. 2, the output is output even when d/D B =1.0 because the pressure in the flow path is detected.

た、本発明では選別と計数の一方を実行させる場
合でもそれぞれの用途において効力を発揮する。 Therefore, in Figure 1, if we define the diameter of the ball at which the cleaning effect is sufficiently effective as point f, we can set the limit amount in that case. That is, as shown in Fig. 3, with the output for the pressure of the flow path as the base, the peak when the ball passes appears depending on the ball diameter, so the numbers a 1 , a 2 ,
It can be seen that a control signal can be easily obtained by counting a 3 , a 4 and the small numbers b 1 , b 2 , b 3 by the arithmetic processor 10 and discharging only the worn small balls out of the system. . It goes without saying that this data is only a small portion. Furthermore, the present invention is effective in both applications even when performing either sorting or counting.
