Description

Technical Field

[0001] The utility model belongs to the technical field of liquid detection, in particular to a multifunctional suspension liquid quality detection system. Background Art

[0002] In the production process of chemical, pharmaceutical and other industries, it is often necessary to detect the quality of suspension liquids, as well as the concentration and color changes of liquids. At present, the main methods for detecting suspension liquids are analyzers (such as oil cleanliness analyzers, engine oil quality analyzers, etc.), sampling density detection, and manual visual inspection.

[0003] The above detection methods each have their own technical characteristics, but still have the following defects:

[0004] 1. When using an analyzer for testing, sampling is required in advance, and then the instrument is used for testing, which makes it impossible to achieve real-time monitoring;

[0005] 2. When using sampling density detection, the instrument needs to be weighed after sampling, which is a cumbersome process;

[0006] 3. When using manual visual inspection, manual inspection windows must be left on the instrument and equipment pipelines, which cannot meet explosion-proof requirements. At the same time, on-site inspections are required, which is inefficient and data cannot be recorded.

[0007] In view of the above-mentioned defects that still exist, a multifunctional suspension quality detection system is proposed. Utility Model Content

[0008] The purpose of the utility model is to provide a multifunctional suspension quality detection system in order to solve the above-mentioned problems.

[0009] The technical solution adopted by the utility model is as follows: a multifunctional suspension quality detection system, including a detection component, a transmitter and a control terminal installed on a pipeline or a box wall, the detection component includes a sensor probe and an optical fiber signal line, a liquid inlet and outlet channel is opened horizontally through the upper side of the sensor probe, a probe optical fiber is accommodated inside the sensor probe, the tail end of the probe optical fiber is communicatively connected to the transmitter through the optical fiber signal line for receiving and / or sending optical signals, and the transmitter is communicatively connected to the control terminal.

[0010] In a preferred embodiment, a glass head in contact with the liquid inside the liquid inlet and outlet channel is installed at the front end of the optical fiber signal line.

[0011] In a preferred embodiment, the outer end surface of the sensor probe is provided with a thread, and a limit nut is threadedly installed on the trailing side of the thread.

[0012] In a preferred embodiment, the probe optical fiber and the liquid inlet and outlet channel are relatively perpendicular.

[0013] In a preferred embodiment, the control terminal is a computer.

[0014] In a preferred embodiment, the sensor probe body is made of 316 stainless steel.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0016] 1. In the utility model, a detection system for real-time detection of the quality of the suspension liquid is designed. During detection, the optical signal is refracted back to the return light channel through the liquid passage, and the current signal of the analog quantity is output after data analysis by the transmitter and transmitted to the control terminal. The control terminal determines the liquid state by the change of the analog quantity, and can automatically monitor whether the suspension liquid is deteriorated and turbid in real time, which can speed up production efficiency and improve production benefits;

[0017] 2. In the present invention, when the state of the liquid changes, the density and color of the liquid will cause the refractive index to change, and then the amount of returned light will change. The condition of the liquid can be judged by simply receiving the amount of returned light refracted by the light signal through the oil, so that it can be applied in complex liquid environments and can accurately judge in turbid, thick, and colored liquids;

[0018] 3. In the utility model, the sensor probe is an integrated structure as a whole, and a mounting part for fixing on a pipe or box for convenient installation is designed on the sensor probe. The structure is simple and reliable, and it is also convenient to install the whole at a desired position. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] Reference Figure 1-2 A multifunctional suspension quality detection system includes a detection component 1 installed on a pipeline or a box wall, a transmitter 2 and a control terminal 3. The detection component 1 includes a sensor probe 102 and an optical fiber signal line 106. A liquid inlet and outlet channel 101 is opened horizontally through the upper side of the sensor probe 102. A probe optical fiber 105 (including a transmitting optical fiber bundle and a receiving optical fiber bundle) is accommodated inside the sensor probe 102. The tail end of the probe optical fiber 105 is connected to the transmitter 2 through the optical fiber signal line 106 for receiving and / or sending optical signals. The transmitter 2 is connected to the control terminal 3 for communication. A detection system for real-time detection of the quality of suspended liquid is designed. Before the detection, the sensor probe 102 is installed on the pipeline or the wall of the box, and the probe is immersed in the suspended liquid. The optical signal is refracted back to the optical channel through the liquid passage. After data analysis by the transmitter 2, the output analog current signal is transmitted to the control terminal 3. The control terminal 3 determines the liquid state through the change of the analog quantity. It can automatically monitor in real time whether the suspended liquid is deteriorated and turbid. It can be used in oil pipeline quality monitoring, pharmaceutical production, lubricating oil hydraulic oil level detection and oil quality detection, which can speed up production efficiency and improve production benefits.

[0024] The working process of transmitter 2 is as follows: light generation, transmission and reception → analysis of light return signal and internal logic operation → sending result to control terminal 3. As a small data transceiver computing platform installed in the electrical box, transmitter 2 has strong anti-interference and adaptability, and is suitable for various complex liquid path detection conditions.

[0025] It should be noted that the probe optical fiber 105 emits laser and receives light, which is an existing technology that has been realized, and the specific structure and circuit will not be explained here.

[0026] Furthermore, a glass head is installed at the front end of the optical fiber signal line 106, which is in contact with the liquid inside the liquid inlet and outlet channel 101. When the sensor probe (glass head) is placed in the air, the laser will be refracted back to the receiving end, and the return amount is the largest. When the glass head contacts the liquid or oil, part of the light is refracted into the liquid, and the return amount is reduced. When the liquid state changes, the density and color of the liquid will cause the refractive index to change, and then the amount of returned light will change. By determining the change in the amount of incoming light, the change of the liquid in the pipeline can be detected. It is only necessary to receive the amount of returned light refracted by the optical signal through the oil to determine the condition of the liquid, so that it can be used in complex liquid environments and can accurately determine turbid, thick, and colored liquids.

[0027] Furthermore, a thread 103 is provided on the outer end face of the sensor probe 102, and a limiting nut 104 is threadedly installed on the rear side of the thread 103. The sensor probe 102 as a whole is an integrated structure, and a corresponding installation part is designed on the sensor probe 102 for fixing on a pipe or box for convenient installation. The structure is simple and reliable, and it is also convenient to install the whole at a desired position.

[0028] The thread 103 can be customized as a straight thread or a pipe thread according to actual needs.

[0029] Furthermore, the probe optical fiber 105 is relatively perpendicular to the liquid inlet and outlet channel 101 , thereby ensuring that the light can directly penetrate into the liquid inside the liquid inlet and outlet channel 101 , thereby ensuring the measurement accuracy.

[0030] Furthermore, the control terminal 3 is a computer.

[0031] Furthermore, the main body of the sensor probe 102 is made of 316 stainless steel. Since the sensor probe 102 is made of stainless steel, the sensor probe 102 as a whole can be used in harsh environments such as corrosion, thereby improving the applicability and service life of the sensor probe 102 as a whole.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
