Problems solved by technology

Due to the relationship between turbidity and light scattering and transmission, at present, the photoelectric method is mainly used to measure turbidity at home and abroad. The principle is to detect the degree of obstruction when light passes through water samples. Environmental interference, so that the accuracy of turbidity measurement is not high

Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] In the prior art turbidity detection devices, the light sources used are usually incandescent lamps, tungsten lamps or different light bulb / filter combinations. Due to the wide spectrum of the polychromatic light source, the light scattering effect of different wavelengths is quite different, which leads to the influence of ambient light, and the measurement accuracy is not high. At the same time, the turbidity values ​​measured by different turbidity detection devices lack comparability.

[0032] In order to solve the above technical problems, the present invention proposes an infrared turbidity detection device, see figure 1 , is shown as a functional block diagram of the infrared turbidity detection device of the present invention, including a power supply module, an infrared light emitting module, an infrared light receiving module, a signal amplification mo...

Abstract

The invention discloses an infrared turbidity detection device, which comprises a power supply module, an infrared light emitting module, an infrared light receiving module, a signal amplification module, a control module and a display module, wherein the power supply module is used to output a constant DC voltage; the infrared light emitting The module is placed above the liquid to be measured, so that the infrared light emitted by the infrared light emitting module is vertically incident on the surface of the liquid to be measured; the infrared light receiving module receives the scattered light scattered by the measured liquid; the signal amplification module is connected with the infrared light receiving module and the control The modules are connected to amplify the output signal of the infrared light receiving module and sent to the control module; the control module is connected to the display module to receive the signal from the signal amplifying module and control the display module to display information. By adopting the technical solution of the invention, the influence of chromaticity and background light on the turbidity measurement can be eliminated, and the infrared light receiving part adopts two-stage amplification, thereby improving the turbidity measurement precision.

Description

technical field [0001] The invention relates to the technical field of water quality detection equipment, in particular to an infrared turbidity detection device. Background technique [0002] With the continuous improvement of people's living standards, people's requirements for drinking water quality are also constantly improving. Turbidity is one of the important indicators to indicate the quality of water, and it is also an important basis for evaluating the purification efficiency of water treatment equipment and the state of water treatment technology. The turbidity of water is closely related to the following factors: (1) the content of suspended solids and colloidal substances (collectively referred to as turbidity) in water; (2) the content of heavy metals in water; (3) the content of organic pollutants (organic carcinogens) in water; therefore, the content of water Turbidity detection, especially online detection is very important. [0003] A turbidimeter is an i...
