Description

Technical Field

[0001] The utility model belongs to the field of detection technology, and in particular relates to a visual flow pool detection structure. Background Art

[0002] In industrial production and process control, many processes require real-time monitoring of various fluid parameters, such as pH, density, and temperature, to ensure process stability and product quality. As a device that enables intuitive observation of fluid conditions and online testing, sight glass inspection devices are widely used in the petroleum, chemical, pharmaceutical, and food industries. By installing a visual flow cell inspection structure on a pipeline or container, fluid characteristics such as color, flow rate, and bubbles can be directly observed, further assisting in fluid composition analysis, reaction monitoring, and quality control.

[0003] Although the existing visual flow pool detection structure can meet certain detection needs, it still has some technical deficiencies in actual application. First, the fluid inlet and outlet are usually set horizontally, which causes turbulence or turbulence when the fluid flows through the detection area, thereby affecting the detection accuracy. Secondly, the existing devices are usually not designed with a structure to prevent impact. When the fluid directly hits the detection head of the detector, it is easy to cause unstable detection data and even damage the detector. In addition, the installation method of the detector is generally relatively fixed, which is not convenient for daily disassembly and maintenance, increasing the downtime and maintenance cost of the equipment.

[0004] Furthermore, the connection parts of many existing devices have poor durability when exposed to corrosive fluids such as acids and alkalis, and the materials are easily corroded, shortening the device's service life. To address these issues, the market has placed higher demands on visual flow cell detection structures that provide fluid guidance, strong corrosion resistance, and easy maintenance. Therefore, providing a visual flow cell detection structure with a reasonable structure, high detection accuracy, and convenient installation and maintenance to meet the needs of online fluid detection in complex environments has important technical value and practical significance. Utility Model Content

[0005] To solve the above problems, the utility model provides a visual circulation pool detection structure. By setting up multiple detection interfaces and corresponding detection equipment, it can monitor multiple parameters of the fluid in the cavity, ensure the fluidity of the medium and the accuracy of detection, and facilitate real-time monitoring and maintenance of the system.

[0006] The technical solutions provided by this utility model are as follows:

[0007] A visual flow pool detection structure includes a viewing mirror with a cavity inside. The cavity is provided with an inlet, an outlet, and at least one detection port. A detector is installed at the detection port, and one end of the detection head of the detector extends into the cavity.

[0008] In some embodiments, the axis of the inlet is perpendicular to the axis of the outlet.

[0009] In some embodiments, a baffle is provided at the inlet, and the baffle is inclined toward the outlet.

[0010] In some embodiments, the detector is detachably mounted at the detection port via a connector, and one end of the connector is connected to the detection port.

[0011] In some embodiments, one end of the connector is provided with a thread, and the detector is screwed onto the connector via the thread.

[0012] In some embodiments, the connector is connected to the detection port by heat melting.

[0013] In some embodiments, the material of the connecting piece and the detection port is PVDF.

[0014] In some embodiments, the detector is a pH meter or a density meter.

[0015] In summary, the beneficial effects of the present invention are as follows:

[0016] (1) The utility model adopts a vertical arrangement of the inlet and outlet axes, and sets an inclined baffle at the inlet, so that the fluid maintains a smooth flow when flowing through the cavity, avoiding the interference of turbulence on the detection data, and ensuring the accuracy of the detection results. The setting of the baffle can also guide the fluid impact to the outlet direction, thereby preventing the fluid from directly hitting the detection head of the detector, reducing the wear and impact of the detector during use, and extending the service life of the detector. This not only reduces the maintenance frequency of the equipment, but also reduces the cost of replacing the detector.

[0017] (2) The detector of the utility model is installed with a connector, one end of which is connected to the detection port, and the other end is fixed to the detector by means of a thread or a snap, so that the detector can be detachably installed, which is convenient for users to install, disassemble and maintain the detector, reduces the downtime of the equipment and improves the efficiency of use.

[0018] (3) The connector and detection port of this utility model are made of corrosion-resistant PVDF material, which can effectively resist the erosion of corrosive fluids such as acids and alkalis, ensuring the reliability of the equipment in complex environments. The high durability of PVDF material is suitable for detection applications with corrosive media such as chemical and pharmaceutical industries, extending the overall service life of the visual flow cell detection structure.

[0023] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0024] Example 1

[0025] like Figure 1-2 As shown, this embodiment provides a visual flow cell detection structure, including a viewing mirror 1, which contains a cavity 2. The cavity 2 is provided with an inlet 3, an outlet 4, and a detection port 5. The inlet 3 and outlet 4 are used for the entry and exit of fluids. The detection port 5 is used to install a detector 6. The detection head of the detector 6 extends into the cavity 2, thereby directly detecting the parameters of the fluid flowing through the cavity 2.

[0026] To achieve multi-directional detection, the detector 6 can be a pH meter, a density meter, or other different types of detectors 6, which can be easily replaced according to different detection requirements. Of course, multiple detection ports 5 can also be provided on the cavity 2 to install different detectors 6. For example, a pH meter can be used to detect the pH value of a fluid, while a density meter can be used to measure the density of a fluid. In addition, this structure is also compatible with other types of detectors, such as thermometers, oxygen detectors, turbidity detectors, etc., thereby making the application range of the visual flow cell detection structure even wider.

[0027] The detection port 5 is preferably located in the middle of the cavity 2 to avoid detection errors caused by changes in the flow rate of the fluid inlet and outlet. At the same time, as the fluid flows through the cavity 2, the detection head 6 can contact a sufficient amount of fluid, ensuring the accuracy and stability of the detection data.

[0028] Example 2

[0029] On the basis of Example 1, this embodiment further optimizes the arrangement of the inlet 3 and the outlet 4, and adds a baffle 7 to optimize the fluid flow.

[0030] The axis of inlet 3 is perpendicular to the axis of outlet 4, forming a 90-degree angle between them. This design primarily reduces excessive or uneven fluid flow within cavity 2, ensuring that detector 6 can accurately detect relevant fluid parameters. After entering cavity 2 through inlet 3, the fluid flows through the interior of cavity 2 and is ultimately discharged through outlet 4.

[0031] The vertical arrangement improves the flow stability of the fluid within cavity 2, preventing sudden changes in flow rate from affecting detection accuracy. Furthermore, the vertical arrangement of the inlet 3 and outlet 4 axes effectively reduces direct impact of the fluid on the detection head, extending the detection accuracy and service life of the detection instrument.

[0032] This embodiment further includes a baffle 7 at the inlet 3, which is inclined toward the outlet 4. The baffle 7 primarily serves to initially guide the fluid after it enters the cavity 2, ensuring a relatively stable flow within the cavity 2. This baffle effectively prevents the fluid from directly impacting the test head, minimizing disturbances caused by the fluid flow and ensuring the accuracy of the test results.

[0033] The baffle 7 is preferably integrally injection-molded with the cavity 2. In this embodiment, it is made of corrosion-resistant plastic, which offers high corrosion resistance while maintaining structural stability. The baffle 7 is integrally molded and fixed within the inlet 3. Its inclination angle can be adjusted based on the actual fluid flow rate and detection requirements to achieve optimal diversion.

[0034] Example 3

[0035] Based on the above embodiments, this embodiment further optimizes the installation method and material selection of the detector 6.

[0036] To facilitate disassembly and maintenance, detector 6 is detachably mounted to detection port 5 via connector 8. One end of connector 8 is connected to detection port 5 via a threaded or bayonet connection, and the other end is connected to detector 6. This detachable design allows for easy installation and removal of detector 6, facilitating regular calibration and maintenance, and improving the practicality of the detection structure.

[0037] In practical applications, different types of detectors 6 can be selected according to detection requirements, such as pH meters, density meters, thermometers, etc. When the detector 6 needs to be replaced or repaired, the operator only needs to remove the detector 6 from the connector 8 and reinstall it after replacement. The process is simple and convenient.

[0038] This embodiment further optimizes the connection between connector 8 and detector 6. Preferably, one end of connector 8 is threaded, allowing detector 6 to be screwed to connector 8. This design ensures the stability of detector 6 and prevents it from loosening under fluid impact. Furthermore, the threaded connection provides excellent sealing, effectively preventing fluid leakage.

[0039] The connector 8 is made of high-strength material and has an anti-corrosion treatment on its surface to adapt to working environments with long-term contact with chemical media. The thread specifications of the connector 8 can be customized according to actual needs to adapt to different types of detector interfaces.

[0040] Alternatively, the connector 8 and the detection port 5 can be connected by heat-melting. This ensures a stable and airtight connection, preventing loosening or leakage caused by external forces. It is particularly suitable for use in high-pressure or high-temperature working conditions. After heat-melting, the connector 8 and the detection port 5 become one, further enhancing the durability of the structure.

[0041] In this case, if the detector 6 needs to be replaced, it is only necessary to remove the detector 6 from the connector 8 without modifying the connection portion between the connector 8 and the detection port 5, thereby further simplifying the maintenance process of the detector.

[0042] To ensure the corrosion resistance and durability of the detection structure, the connector 8 and the detection port 5 are preferably made of polyvinylidene fluoride (PVDF). PVDF has excellent acid and alkali resistance and maintains high stability in harsh environments such as high temperature and high pressure. In addition, PVDF has a low coefficient of thermal expansion, which can effectively reduce the impact of temperature changes on the sealing effect.

[0043] By selecting PVDF material, it can be ensured that the visual flow cell detection structure is suitable for the detection of various highly corrosive media, extending the service life of the equipment and reducing maintenance costs.
