Description

Technical Field

[0001] The utility model relates to the technical field of water pollution degree detection, in particular to a water pollution degree measurement terminal correction device. Background Art

[0002] In the field of water pollution measurement, since there are many target objects and some of them are corrosive, oily or solid substances, the measuring equipment is easily affected by previous residues after repeated measurements, resulting in deviations in the test results. The more common practice in the existing technology is to regularly calibrate and clean or replace the filter device.

[0003] Unfortunately, even if the above-mentioned common methods are adopted, they are still mostly based on experience-based judgment or scheduled maintenance, and are prone to excessive or ineffective labor. Therefore, a precise auxiliary measurement device is needed that can be used for end-point supplementary testing, calibration of equipment test results, digital and accurate understanding of equipment status, and is available at any time.

[0004] Therefore, there is an urgent need on the market for a water pollution measurement terminal correction device that can correct terminal results, detect the status of measurement equipment, and has high reliability and good operability. Utility Model Content

[0005] The utility model aims to provide a water pollution degree measurement terminal correction device which can correct terminal results, detect the status of measuring equipment, and has high reliability and good operability.

[0006] In order to achieve the above-mentioned object, the utility model adopts the following technical solutions: a water pollution degree measurement terminal correction device, which is provided with a liquid inlet, a housing, a filtering device, three sets of measuring devices, a signal processing device matched with the measuring devices, a mechanical stirring device for mixing the liquid flow uniformly, and a liquid outlet according to the correction work flow;

[0007] The liquid inlet is arranged outside the top of the shell and is connected to the filter device arranged inside the top of the shell. The liquid flows through the filter device to filter out large solids and then enters the shell.

[0008] Three sets of measuring devices are provided inside the housing, each consisting of a quantitative sampler and a test solution analysis device; each measuring device is provided with a signal output terminal, which is connected one-to-one with the signal processing device. The signal processing device is provided with an external signal encryption receiving device and a detection signal sending device. After the measurement result signal is compared with the signal given by the signal receiving unit received by the external signal encryption receiving device through the signal processing device, the result is sent out through the detection signal sending device;

[0009] The bottom of the shell is also provided with a mechanical stirring device, and a liquid outlet is provided below the mechanical stirring device.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] (1) The present invention is suitable for terminal calibration, that is, when the inspection equipment is about to be overhauled or when it is under extreme working conditions such as long-term inspection of highly corrosive water, the sampled water body is subjected to terminal inspection and result matching, and accurate results and effective data for the status of the main inspection equipment can be obtained at the same time. It provides data support for whether to advance or extend the inspection of the equipment, and for the establishment of inspection aspects (parts with large deviations during calibration need to be inspected or replaced in a focused manner), thereby reducing dependence on experience, reducing maintenance time, improving results, and reducing costs (parts with relatively accurate inspection results do not need to be replaced).

[0012] (2) The overall design of the utility model is based on a large amount of production practice experience data combined with liquid simulation of solid-liquid mixtures. The sampling device and the analysis device are combined with the stirring device to be respectively arranged at the upper, middle and lower ends of the shell and offset to the left and right. This can obtain more comprehensive and accurate results while improving the reliability and durability of the equipment.

[0013] Therefore, the utility model has the characteristics of terminal result correction, detection of measurement equipment status, high reliability and good operability. BRIEF DESCRIPTION OF THE DRAWINGS
