Description

Technical Field

[0001] The utility model belongs to the technical field of liquid detection, and in particular relates to a liquid sampling detection device and a liquid sampling detection assembly. Background Art

[0002] In the field of chemical industry or sewage treatment, it is usually necessary to sample liquid on a reactor (such as a reactor or a treatment tank) and detect the sampled liquid. At present, the sampling method is mostly to set a sampling port on the reactor and set a valve at the sampling port (such as the content recorded in the document No. CN114577538A "Sampling Device"). Usually, the valve sampling port is opened before detection, which makes its detection efficiency low. At the same time, there is a certain risk when sampling, especially when the liquid in the reactor is corrosive or pressurized, which is even more inconvenient. In addition, there is also a method of directly embedding the detection sensor on the reactor, and directly using the detection sensor to detect the liquid in the reactor, but when the number of detection sensors is large, it is necessary to set a large number of embedding sites on the reactor, which affects the structural strength of the reactor and makes it inconvenient to maintain the detection sensor.

[0028] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention. The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer according to the following description and claims. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0029] Example 1

[0030] like Figure 1 and Figure 2 As shown, the present embodiment provides a liquid sampling detection device, including a detection tank 11, wherein a mounting hole 111 is provided at the upper end of the detection tank 11, wherein the mounting hole 111 is used for sealingly mounting a detection sensor 112, and the sensing portion of the detection sensor 112 extends into the detection tank 11, and a liquid inlet 113 and a liquid outlet 114 are further provided on the detection tank 11, and the liquid inlet 113 is located below the liquid outlet 114, and the horizontal height of the sensing portion of the detection sensor 112 is lower than the horizontal height of the liquid outlet 114, so that liquid can be directly taken in from the liquid inlet and discharged from the liquid outlet, and then the detection sensor in the detection tank detects the liquid flowing through the detection tank, so that direct online detection is possible without sampling.

[0031] In the above technical solution, the liquid inlet 113 and the liquid outlet 114 are both located on the side wall of the detection tank 11, so that the liquid in the detection tank flows from bottom to top (overflows in an overflow manner), thereby ensuring that the liquid level in the detection tank can meet the detection requirements of the detection sensor.

[0032] In the above technical solution, the detection tank 11 is also provided with a sewage outlet 115, and a sewage valve 116 is provided at the sewage outlet 115, so that after dirt is deposited in the detection tank, it can be regularly flushed and discharged.

[0033] The level of the sewage outlet 115 in the above technical solution is lower than the level of the liquid inlet 113, so as to avoid the impact of the dirt inside the detection tank after the fluid enters the tank, and prevent the dirt from flowing out with the liquid.

[0034] The sewage outlet 115 in the above technical solution is arranged at the lower end of the detection tank 11, and has a simple structure, which is conducive to more thorough sewage discharge when flushing dirt in the detection tank.

[0035] In the above technical solution, a plurality of mounting holes 111 are provided, and a detection sensor 112 is sealed and installed at each mounting hole 111, so that a plurality of detection sensors can be installed on the detection tank at the same time to measure multiple indicators of the liquid.

[0036] The volume of the detection tank 11 in the above technical solution is 0.2-10L, its structure is simple, and its volume can be determined according to needs.

[0037] The inner wall of the detection tank 11 in the above technical solution is coated with an anti-corrosion coating, so that the detection tank has a good anti-corrosion effect and good durability.

[0038] Preferably, Figure 3 As shown, the lower end of the detection tank 11 is in an inverted cone or pot shape, so that the sewage outlet is arranged at the lowest level of the lower end of the detection tank.

[0039] The liquid sampling and detection device described in this embodiment can be applied to the chemical industry, sewage treatment or water quality detection field. For example, waste heat power generation, like many power generation processes that convert heat energy into electrical energy, requires water quality detection during the heat exchange process to ensure that the water quality meets the requirements of production and that the corrosion and erosion damage of water and steam in each heat exchange equipment is minimized. Traditional water quality detection and testing are all done by on-site sampling by chemical water personnel, and then the samples are taken back to the chemical water analysis room for manual testing, which is lacking in timeliness and manpower allocation. The liquid sampling and detection device provided in this embodiment can directly detect water quality online.

[0040] As described in this embodiment, the detection sensor may be a conductivity sensor, a pH sensor, a turbidity sensor, a TOC sensor, etc., which will not be elaborated here. The type of the detection sensor can be flexibly selected according to actual needs.

[0041] In this embodiment, each detection sensor can be electrically connected to a terminal device (such as a computer), so that the terminal device analyzes and displays the data detected by the detection sensor.
