光窓部を設け、投光器より投光窓部を経て受光窓部に向
かって光を投射し、受光窓部を通過した透過光を受光器
で受け、この透過光の減衰度合から液の濁度を計測する
方式のものであった。Conventional turbidity meters have a light transmitting window and a light receiving window made of transparent plates such as glass on the opposing walls of a pipe through which polluted water flows, and the light is transmitted from the projector through the light transmitting window to the light receiving window. It was a method in which light was projected towards the liquid, the transmitted light that passed through the light receiving window was received by a light receiver, and the turbidity of the liquid was measured from the degree of attenuation of this transmitted light.

れる汚物が窓部に付着堆積し、光の透過を阻害する。こ
のため、頻繁に窓部の掃除を行わなければ濁度計による
被検液の濁度測定が不正確になるという問題があり、取
り扱いが非常に煩雑であった。If the turbidity meter is used continuously, dirt contained in the test liquid such as polluted water will adhere to and accumulate on the window, obstructing the transmission of light. For this reason, there is a problem that unless the window portion is cleaned frequently, the turbidity measurement of the test liquid by the turbidity meter becomes inaccurate, and the handling is very complicated.

確な濁度測定ができなくなるため、洗毛品質が安定しな
かった。For example, in a sheep wool washing factory where raw sheep wool is washed in a washing tank, the degree of cleaning completion is determined from the degree of contamination of the wastewater discharged from the washing tank, and the amount of detergent supplied to the washing tank and the amount of supplementary water are artificially controlled. However, the window quickly became contaminated with fat and dirt that had adhered to the wool, making it impossible to measure turbidity accurately, resulting in unstable washing quality.
したがって、この発明の目的は、窓部を簡単に洗浄する
ことができ、濁度測定を高い精度でかつ安定して行うこ
とができる濁度計測装置を提供することである。Therefore, an object of the present invention is to provide a turbidity measuring device that can easily clean the window and perform turbidity measurement with high precision and stability.

とを備えたものである。The turbidity measuring device of the present invention includes a turbidity measuring tube having a test liquid supply pipe and a discharge pipe connected to both ends thereof, and having a light emitting window and a light receiving window for turbidity measurement on mutually opposing walls. , interposed between this turbidity measuring tube and either one of the supply pipe and the discharge pipe.
Liquid? A three-way valve capable of switching between the J state and a cutoff state in which the test liquid does not flow; and a three-way valve that is coaxially connected to the turbidity measurement tube through the three-way valve, and a state in which the flow of the test liquid is blocked by the three-way valve. a brush storage that communicates with the turbidity measuring tube in the cutoff state, and in this cut-off state, houses a cleaning brush that protrudes freely forward and backward into the turbidity measuring tube through the three-way valve and reaches the light emitting window section and the light receiving window section; It is equipped with a tube.

うことができる。According to this invention, when the light emitting window and light receiving window in the turbidity measuring tube become contaminated due to turbidity measurement of the test liquid, the three-way valve is switched to the cutoff state and the three-way valve is removed from the brush storage tube. After that, the cleaning brush can be protruded into the turbidity measuring tube to clean these windows, so the windows can be cleaned easily and quickly. Therefore, even if the test liquid is a polluted liquid containing a large amount of oil and fat bones (for example, waste water from washing raw sheep wool), the influence of dirt on the window portion is small and accurate measurement can be performed.

効果を高めるのにも効果的である。Also, during turbidity measurement, which is the flow state of the three-way valve,
The cleaning brush is stored in the brush storage tube and does not come into contact with the test liquid, so the brush will not be contaminated with the test liquid, which can extend the life of the cleaning brush. It is also effective in increasing the cleaning effect of the light-transmitting window and the light-receiving window.

A filter 8 is installed at the upstream end 15a to prevent large impurities such as dust flowing through the main pipe 6 from entering. An on-off valve 9 (such as an automatic two-way valve) is provided between the pump 7 and the filter 8. In addition, the main pipe 6 may have a cylindrical shape, a rectangular pipe shape, or a gutter having a concave or semicircular cross section.

The turbidity of the test liquid is measured by the incident light. That is, although not shown, a light passing device is arranged outside the light projecting window section 2 through a condensing lens, and a light receiving device is disposed at the other light receiving window section 3 through a condensing lens. The light transmitted through the tube 1 enters the light receiver, its luminous intensity is measured, and the turbidity is calculated from this and output.

As shown in the figure, the three-way valve 4 is switched to the shutoff state in which the test liquid does not flow. In this state, the brush 5 is projected from the brush storage pipe 11 through the three-way valve 4 to the turbidity measurement pipe 1, and the shirt 5a is rotated by the motor 12. moreover,
The on-off valve 14 of the cleaning liquid supply pipe 13 is opened, the pump 7 is stopped, and the cleaning liquid is supplied to the on-off valve 14 - three-way valve 4 - turbidity meter? ll! I
It flows in the order of tube 1 to supply tube 15, and dirt adhering to the light emitting window 2 and light receiving window 3 of the turbidity measuring tube 1 is washed away by the rotation of the brush 5 and the cleaning power of the cleaning liquid.

Next, the pump 7 is stopped, the two on-off valves 9 and 14 are closed together, and the clean cleaning liquid is sealed inside the turbidity measurement tube 1 and held as it is for a certain period of time. After that, the turbidity measurement (above (a)

。In this way, in this embodiment, the steps of turbidity measurement -> cleaning with the brush 5 - and sealing and holding of the cleaning liquid are repeated, so even if the sample liquid is a polluted liquid containing a large amount of oil and fat bones, it will not be possible to prevent dirt from the windows 2 and 3. Turbidity can be measured accurately with little influence. Furthermore, by increasing the time for which the cleaning liquid is kept sealed, there is an advantage that the number of times of cleaning can be reduced for test liquids whose turbidity changes relatively little over time.

洗毛品質が従来に比べて著しく向上した。At that time, the turbidity of the hair washing waste liquid in the third tank was measured to examine the finished state of the hair washing. That is, the turbidity measurement and washing were repeated in a 10-minute cycle, with the turbidity measurement being carried out for 1 minute, the washing being carried out for 1 minute, and the washing liquid being kept sealed for 8 minutes. The amount of detergent supplied and the amount of make-up water to each washing Pt were determined from the measured value of turbidity, and the hair washing operation was controlled. As a result, the quality of washing hair is stable,
The hair washing quality has been significantly improved compared to the conventional method.
