Turbidity detecting device

Abstract

The invention discloses a turbidity detecting device, which comprises a shell, a detection control integrated circuit and a sensor assembly. The sensor assembly includes an emitter and a receiver. The emitter is a light-emitting element diverging ultraviolet light, and the receiver is a light-receiving element. The light-receiving element is disposed at a position opposite to the light-emitting element, and a certain distance is kept between the light-emitting element and the light-receiving element. According to the invention, the light-emitting element, a first light-transmitting plate, a second light-transmitting plate and the light-receiving element are mounted in the shell from top to bottom, and an opening detection groove is arranged between the first light-transmitting plate and the second light-transmitting plate, so that the detecting device can have the advantages of simple structure, strong anti-interference performance, stable detection performance and easy operation. Making full use of the volatility and corpuscular property of high frequency wave length and optical energy, the device provided by the invention is almost not interfered by the external environment in use, thus effectively realizing turbidity measurement.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a turbidity detection device. Background technique [0002] With the improvement of people's living standards and the continuous deepening of research on the relationship between drinking water and health, people's requirements for drinking water quality are also increasing. Turbidity is a characteristic parameter of the optical properties of water. It is not only one of the important indicators to measure the goodness of water quality, but also an important basis for evaluating the effect of water treatment. Therefore, the online detection of water turbidity has very important practical significance. [0003] In general, the turbidity measurement sensor used to detect the turbidity of the fluid includes: a transmitter (Transmitter) that emits a measurement beam (beam) (usually using high frequency), and is used to receive the beam emitted by the transmitter. The rec...

Problems solved by technology

[0009] The current method of measuring turbidity usually cannot solve the problem of the intensity change of the light source itself, especially the light intensity attenuation after long-term use of the light source. Therefore, the commonly used turbidity meters require the use of standard turbidity liquids to manually adjust the turbidity meter regularly or irregularly. Offline calibration (usually once every three months) not only requires a lot of manpower and material resources, but also is not very realistic in many cases, such as the turbidimeter is installed in a place that is difficult to access, or the calibration will affect the need for continuous online monitoring, In addition, there is no way to process the detection data in a timely and effective manner.
