Description

Technical Field

[0001] This application relates to the field of online refractometer technology, and more particularly to a self-cleaning online refractometer. Background Technology

[0002] Online refractometers are widely used sensors for liquid concentration detection. They measure the refractive index of various liquids and convert it into different liquid parameters. They are typically installed on pipelines. However, because the liquids being measured often contain large amounts of undissolved substances, free organic oils, etc., these substances are viscous and highly absorbent. Even at high flow rates, they can easily cover the measurement window of the online refractometer, leading to increased measurement errors, measurement instability, or even measurement failure.

[0003] The existing solution is to add an automatic cleaning device, which employs different technical approaches for different liquids. For example, ultrasonic cleaning is used for liquids with good flowability and low viscosity; high-pressure water or high-pressure air cleaning is used for liquids with high solids content and low viscosity; and automatic brush cleaning is used for liquids with high viscosity and many impurities. However, each cleaning method has its limitations, and regardless of the method, it will damage the sensor and affect its lifespan. Summary of the Invention

[0004] In view of this, this application proposes a self-cleaning online refractometer.

[0005] According to one aspect of this application, a self-cleaning online refractometer is provided, comprising: a refractometer body and a flow cell conduit;

[0006] The refractometer has a measuring section at the top, a measuring window at the end of the measuring section, and the measuring section is a columnar structure with an inclined end.

[0007] The flow cell pipe is a barrel-shaped structure with open ends and a hollow interior. The measuring part of the refractometer body extends into the side wall of the flow cell pipe, and the inclined surface of the measuring part corresponds to the liquid flow direction in the flow cell pipe.

[0008] In one possible implementation, the end of the measuring unit is provided with an inclined surface, and the measuring window is located on the inclined surface;

[0009] The inclined surface is spaced at a first preset angle from the length direction of the measuring part.

[0010] In one possible implementation, the refractometer body is disposed on the side wall of the flow cell pipe, and the measuring part extends into the interior of the flow cell pipe, with the length direction of the refractometer body and the length direction of the flow cell pipe spaced apart by a second preset angle.

[0011] In one possible implementation, an installation pipe extends from the side wall of the flow pool pipe, the installation pipe is connected to the flow pool pipe, and the length direction of the installation pipe is spaced from the length direction of the flow pool pipe by a third preset angle.

[0012] The refractometer body is sealed and connected to the mounting pipe, and the measuring part of the refractometer body extends into the flow cell pipe through the mounting pipe.

[0013] In one possible implementation, the measuring section has a preset length, the refractometer body is mounted on the mounting pipe, and the end of the measuring section is located inside the flow cell pipe.

[0014] The beneficial effects of the self-cleaning online refractometer in this application embodiment are as follows: By tilting the end of the measuring section of the refractometer and opening the measuring window on the tilted end face relative to the refractometer, and then passing the measuring section of the refractometer through the side wall of the flow cell pipe and extending into the interior of the flow cell, the end face of the refractometer extending into the flow cell pipe can form a preset angle with the flow direction of the detection liquid. The scouring force generated by the flow of the detection liquid cleans the detection window. Since the measuring window uses a sapphire optical prism, the detection liquid or cleaning liquid will not damage the sensor. Therefore, using the method of this application greatly improves the service life of the sensor.

[0025] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0026] Figure 1 A schematic diagram of the main structure according to an embodiment of this application is shown. Figure 1As shown, the self-cleaning online refractometer of this application embodiment includes: a refractometer body 100 and a flow cell pipe 200. The top of the refractometer is provided with a measuring part 110, and the end of the measuring part 110 is provided with a measuring window 111. The measuring part 110 is a columnar structure with an inclined end. The flow cell pipe 200 is a barrel-shaped structure with openings at both ends and a hollow interior. The measuring part 110 of the refractometer body 100 extends into the side wall of the flow cell pipe 200, and the inclined surface of the measuring part 110 corresponds to the liquid flow direction in the flow cell pipe 200.

[0027] In this specific embodiment, the measuring section 110 of the refractometer is tilted at its end, and the measuring window 111 is opened on the tilted end face relative to the refractometer. The measuring section 110 of the refractometer is then passed through the side wall of the flow cell pipe 200 and extended into the interior of the flow cell. This allows the end face of the refractometer extending into the flow cell pipe 200 to form a preset angle with the flow direction of the detection liquid. The scouring force generated by the flow of the detection liquid cleans the detection window. Since the measuring window uses a sapphire optical prism, the detection liquid or cleaning liquid will not damage the sensor. Therefore, the method described in this application greatly improves the service life of the sensor.

[0028] It should be noted that the refractometer is a conventionally available technology, including the refractometer body and data cable, used to measure the refractive index of liquids, which will not be elaborated further here.

[0029] In this specific embodiment, when the refractometer body 100 is placed on the side wall of the flow cell pipe 200, the measuring part 110 of the refractometer body 100 is inserted into the flow cell pipe 200, and the end of the measuring part 110 is provided with an inclined surface, which corresponds to the flow direction of the detection liquid, so that the detection liquid can wash the inclined surface of the measuring part 110.

[0030] In one specific embodiment, the end of the measuring unit 110 is provided with an inclined surface, and the measuring window 111 is located on the inclined surface. The inclined surface is spaced at a first preset angle from the length direction of the measuring unit 110. Thus, when the refractometer body 100 is inserted into the flow cell pipe 200 along the direction perpendicular to the flow of the detection liquid, the flow direction of the detection liquid will be spaced at the first preset angle from the end of the measuring unit 110 with the measuring window 111. This allows the detection liquid to flush the detection window, completing the measurement of the detection liquid while also self-cleaning the detection window.

[0031] In one specific embodiment, the refractometer body 100 is disposed on the side wall of the flow cell pipe 200, and the measuring part 110 extends into the interior of the flow cell pipe 200. The length direction of the refractometer body 100 is spaced at a second preset angle from the length direction of the flow cell pipe 200. The end face of the measuring part 110 with the measuring window 111 is inclined and not easily adjustable. Therefore, the angle between the measuring part 110 end face and the flow direction of the detection liquid can be adjusted by adjusting the angle between the refractometer body 100 and the flow cell pipe 200.

[0032] In one specific embodiment, an installation pipe 300 extends from the side wall of the flow cell pipe 200. The installation pipe 300 is connected to the flow cell pipe 200, and the length direction of the installation pipe 300 is spaced apart from the length direction of the flow cell pipe 200 by a third preset angle. By setting the refractometer body 100 on the installation pipe 300, and because the installation pipe 300 is spaced apart from the flow cell pipe 200 by the third angle, a certain angle can be generated when the refractometer body 100 is installed on the installation pipe 300.

[0033] The refractometer body 100 is sealed and connected to the mounting pipe 300, and the measuring part 110 of the refractometer body 100 extends into the flow cell pipe 200 through the mounting pipe 300. The refractometer body 100 is sealed and mounted on the mounting pipe 300, the measuring part 110 has a preset length, and the end face of the refractometer body 100 with the measuring window 111 is located inside the flow cell pipe 200.

[0034] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
