[0014] Compared with the prior art, the beneficial effects of this application are as follows:

[0015] (1) This invention proposes a urea solution detection device, which is equipped with a detection tank, a mounting shell, an inlet pipe, a mounting frame, a filter screen, a scraping component, a baffle component, and a drain pipe. The solution enters the mounting shell through the inlet pipe, where impurities are filtered by the filter screen. The sliding component drives the scraping component and the rotating rod to rotate through the plug-in component to scrape the filter screen surface. The baffle component moves synchronously with the scraping component to prevent impurities from being carried away by the solution.

[0016] (2) This invention proposes a urea solution detection device, which is equipped with a rotating rod, a baffle plate, a guide plate and a protective plate. The urea solution is guided by the guide plate to the filter screen or the baffle plate to prevent it from flowing down from the gap between the baffle plate and the mounting shell and affecting the filtration. When the solution falls, the part that is not blocked by the baffle plate will be filtered by the filter screen and flow into the detection tank. The part that is blocked by the baffle plate will flow down along the inclined end to the part that is not blocked by the filter screen, so as to avoid impurities being carried away when scraping the material, thereby preventing secondary pollution by impurities and improving the detection accuracy.

[0017] (3) The present invention proposes a urea solution detection device, which is equipped with an installation plate, a scraper and a collection box. The installation plate is rotated by a sliding component and a plug-in component, which causes the scraper to rotate accordingly. During the rotation, the scraper scrapes off the impurities at the bottom of the filter screen. The scraped impurities fall into the collection box for collection, which realizes efficient cleaning and collection of filter screen impurities and improves the detection accuracy.

[0025] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0027] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0028] One preferred embodiment of this application, such as Figures 1 to 6 As shown, a urea solution testing device includes: a testing tank 1, with a mounting shell 9 threadedly connected to the center of the top of the testing tank 1; and further includes: an inlet pipe 10, a mounting frame 11, a filter screen 12, a scraping assembly, a baffle assembly, and a drain pipe 13. The inlet pipe 10 is vertically fixed to the top of the mounting shell 9; the mounting frame 11 is horizontally fixed to the middle of the inner circumference of the mounting shell 9; the filter screen 12 is arranged in a ring and fixedly installed at the bottom of the mounting frame 11; the scraping assembly has plug-in assemblies at both ends of its bottom, one set of which is slidably installed on the bottom of the inner circumference of the mounting shell 9 via a sliding assembly for scraping the bottom of the filter screen 12; the baffle assembly is located on the top of the mounting frame 11 and moves together with the scraping assembly to prevent impurities scraped off by the scraping assembly from being carried away when the material flows through the filter screen 12; the drain pipe 13 is horizontally fixed to the bottom outer wall of the testing tank 1, and a one-way valve is fixedly installed on the inner circumference of the drain pipe 13.

[0029] First, the solution enters the mounting housing 9 through the inlet pipe 10, filters impurities through the filter screen 12, and then the sliding component is activated. The sliding component drives the scraping component to rotate through the plug-in component, scraping the surface of the filter screen 12. At the same time, the baffle component prevents the solution from falling onto the part of the filter screen 12 that is being scraped, and moves together with the scraping component to prevent impurities from being carried away. The filtered clean solution flows into the detection tank 1, and after the detection is completed, it is discharged through the drain pipe 13. The mounting housing 9 is opened periodically, and the scraping component is removed through the plug-in component for timely cleaning and replacement, preparing it for the next use. This achieves efficient cleaning of filter screen impurities, while preventing secondary contamination by impurities and improving detection accuracy.

[0030] Further reference Figures 3-6 The sliding assembly includes an electric slide rail 201 and an electric slider 202. The electric slide rail 201 is arranged in a ring shape and is fixedly installed on the bottom of the inner circumference of the mounting housing 9. The electric slider 202 is slidably installed on the electric slide rail 201.

[0031] The electric slide rail 201 and the electric slider 202 ensure that the scraper assembly and the plug assembly rotate together.

[0032] Further reference Figures 2-6 The mounting bracket 11 has a rotating rod 301 rotatably mounted on its inner circumference. The baffle assembly includes a baffle plate 302, which is semi-circular in shape. One end of the baffle plate 302 is fixedly mounted to the top of the rotating rod 301, and the other end of the baffle plate 302 is inclined upward.

[0033] The sliding assembly is activated, which drives the rotating rod 301 to rotate via the scraping assembly and the plugging assembly. The semi-circular baffle 302 rotates synchronously. If the falling solution comes into contact with the surface of the filter screen 12 that is not blocked by the baffle 302, it will fall into the detection tank 1 after filtration. If the falling solution comes into contact with the surface of the baffle 302, the other end of the baffle 302 is tilted upwards, so that the solution flows down along the tilt angle until it comes into contact with the surface of the filter screen 12 that is not blocked by the baffle 302. This prevents the material from flowing through the part of the filter screen 12 that is being scraped while the scraping assembly is scraping the surface of the filter screen 12, thereby carrying away the impurities scraped off by the scraping assembly, thus preventing secondary contamination by impurities and improving the detection accuracy.

[0034] Further reference Figure 3 , Figure 5 and Figure 6 The plug-in assembly includes: a mounting slot plate 401 and a plug block 402. The two mounting slot plates 401 are fixedly installed on the bottom of the rotating rod 301 and the bottom of the electric slider 202 near the rotating rod 301, respectively. The two plug blocks 402 are respectively set at both ends of the bottom of the scraper assembly, and the two plug blocks 402 are respectively inserted into the slots of the corresponding mounting slot plates 401.

[0035] When the sliding assembly is activated, the rotating rod 301 rotates together with the scraper assembly via the two mounting slots 401 and the two inserts 402, so that the baffle plate 302 rotates synchronously with the scraper assembly.

[0036] Further reference Figure 3 , Figure 5 and Figure 6 The scraping assembly includes: a mounting plate 501, a scraper 502, and a collection box 505. The mounting plate 501 is horizontally positioned, and its bottom ends are fixedly connected to two insert blocks 402 respectively. The scraper 502 is vertically fixedly installed on one side of the top of the mounting plate 501, and the collection box 505 is fixedly installed on the other side of the top of the mounting plate 501.

[0037] The sliding assembly is activated, and the mounting plate 501 is rotated through the plug-in assembly. During the rotation, the scraper 502 scrapes off the impurities at the bottom of the filter screen 12. The scraped-off impurities fall into the collection box 505 for collection, which realizes efficient cleaning and collection of filter screen impurities and improves the detection accuracy.

[0038] Further reference Figures 2-4 A ring-shaped guide plate 601 is fixedly installed on the top of the inner wall of the mounting shell 9. The end of the guide plate 601 near the rotating rod 301 is inclined downward.

[0039] The other end of the baffle plate 302 is inclined upwards, so there is a gap between the other end of the baffle plate 302 and the inner circumferential wall of the mounting shell 9. The urea solution flows into the outer shell 9 through the inlet pipe 10. After the solution comes into contact with the annular guide plate 601, it flows downwards under the guidance of the guide plate 601 towards the filter screen 12 or the baffle plate 302, preventing the solution from flowing down from the gap between the baffle plate 302 and the mounting shell 9, thereby affecting the filtration of the solution.

[0040] Further reference Figures 3-6 A ring-shaped protective plate 701 is fixedly installed at the bottom of the inner wall of the mounting shell 9. The protective plate 701 is located between the filter screen 12 and the electric slide rail 201. The end of the protective plate 701 near the rotating rod 301 is inclined downward. Several openings 702 are equidistantly opened at the top of the mounting plate 501 away from the rotating rod 301.

[0041] After the solution is filtered through the filter screen 12, it falls into the detection tank 1 along the angle of the inclined protective plate 701 if it comes into contact with the protective plate 701. This prevents the solution from falling onto the sliding component. If the solution on the protective plate 701 falls onto the mounting plate 501, it falls into the detection tank 1 through the opening 702 to prevent it from affecting the plug-in component.

[0042] Further reference Figure 1A controller 801 is fixedly installed on the top of the detection tank 1, and a sensor is installed on the inner wall of the bottom of the detection tank 1. The controller 801 is electrically connected to the sensor and the electric slide rail 201 respectively.

[0043] The electric slide rail 201 is activated by the controller 801. After the solution falls into the detection tank 1, the sensor is activated by the controller 801 to detect the solution and transmit the data back to the controller 801.

[0044] Further reference Figure 3 Several elastic support columns 14 are fixedly installed at equal intervals on the bottom outer wall of the testing tank 1.

[0045] During equipment operation, the elastic support column 14 continuously plays a buffering role, reducing the vibration caused by the operation of internal components.

[0046] Working principle: First, the solution enters the mounting housing 9 through the inlet pipe 10. After contacting the annular guide plate 601, the solution flows downwards at an angle towards the filter screen 12 or the baffle plate 302 under the guidance of the guide plate 601. This prevents the solution from flowing down through the gap between the baffle plate 302 and the mounting housing 9. If the falling solution contacts the surface of the baffle plate 302, the other end of the baffle plate 302 is tilted upwards, allowing the solution to flow down at the angle until it contacts the surface of the filter screen 12 that is not blocked by the baffle plate 302. This prevents the material from flowing through the part of the filter screen 12 that is being scraped while the scraping assembly is scraping the surface of the filter screen 12, thereby carrying away the impurities scraped off by the scraping assembly. Then, the solution passes through the filter screen 12 to filter impurities, and the process is started. The sliding assembly, through the scraping assembly, two mounting slots 401, and two inserts 402, drives the rotating rod 301 to rotate. During the rotation, the scraper 502 scrapes off impurities at the bottom of the filter screen 12. The scraped impurities fall into the collection box 505 for collection. The semi-circular baffle 302 rotates synchronously. If the falling solution comes into contact with the surface of the filter screen 12 that is not blocked by the baffle 302, the filtered solution flows into the detection tank 1. After the detection is completed, it is discharged through the drain pipe 13. The mounting shell 9 is opened periodically, and the scraping assembly is removed through the plug-in assembly. The scraping assembly is cleaned and replaced in time to prepare for the next use. This achieves efficient cleaning of filter screen impurities, while preventing secondary contamination by impurities and improving detection accuracy.
