[0032] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0033] Example 1, please refer to Figure 1-10 The present invention provides a technical solution: an intelligent detection device for product measurement, including a data processor for controlling the execution of the entire measurement and detection process. Specifically, it also includes a measurement tank 1, which is hollow inside and can be designed with transparent material and has scale lines engraved on its surface (not shown in the figure). This facilitates users to directly observe the product measurement status and obtain measurement data.

[0034] refer to Figure 1The top of the metering tank 1 is detachably connected to a cover plate 2. The outside of the metering tank 1 is arranged from bottom to top as a base frame 3, a first support plate 4, and a second support plate 5. The base frame 3 is provided in several parts and is evenly fixedly connected to the bottom of the first support plate 4 to form the supporting foundation of the metering tank 1. The first support plate 4 and the second support plate 5 are preferably arranged in a ring to reduce the space ratio. Several support rods 6 are evenly distributed between the first support plate 4 and the second support plate 5. The shape of the support rods 6 includes, but is not limited to, cylindrical. The upper and lower ends of the support rods 6 are fixedly connected to the second support plate 5 and the first support plate 4, respectively. The surfaces of the support rods 6 are slidably connected to a movable rod 7. The other end of the movable rod 7 can be connected to the outer wall of the metering tank 1 by a snap-fit ​​or fixed connection, so that the metering tank 1 can drive the movable rod 7 to descend synchronously. This will not be described in detail here.

[0035] A first support spring 8 is provided below the movable rod 7 that is slidably connected to the surface of the frame rod 6. Specifically, the upper end of the first support spring 8 is in contact with or fixedly connected to the movable rod 7, and the lower end of the first support spring 8 is fixedly connected to a receiving plate 9. The frame rod 6 passes through the receiving plate 9, and a force sensor is embedded between the receiving plate 9 and the opposite side of the first frame plate 4. The force sensor is connected to the data processor signal and can at least be used to determine the position accuracy of the metering tank 1 during initial installation and to analyze the stability of material feeding and discharging during the metering process.

[0036] During the installation of metering tank 1, the base frame 3, first support plate 4, second support plate 5, support rod 6, moving rod 7, first support spring 8, and receiving plate 9 are first installed according to the following steps: Figure 1 The installation is completed at the indicated position, with the force sensor pre-embedded and then the metering tank 1 is centered and connected.

[0037] First, by changing the size of the movable rod 7, this device is suitable for supporting and connecting various models of metering tanks 1, effectively expanding the applicable range of metering tank models. After the installation of metering tank 1 is completed, a tank installation balance analysis is performed based on the detection data of the force sensors. Specifically, the initial detection data of the force sensors is recorded as the initial bearing force gi, where i ranges from 1 to n, n ≥ 2, and n is the total number of force sensors installed. It should be noted that the force sensors are evenly installed on the first support plate 4, and the number does not necessarily need to be the same as the number of supporting plates 9; it should be set according to actual usage requirements. The data processor collects the n sets of initial bearing forces gi and compares the initial pressure difference between any two values, setting... The allowable differential pressure upper limit is gmax. When the initial differential pressure exceeds the allowable differential pressure upper limit, the data processor will display an alarm, informing the user to adjust the support status at the corresponding position of the tank to ensure that the initial differential pressure between any two values ​​of the n initial bearing capacities does not exceed the allowable differential pressure upper limit. This ensures that the tank is in a balanced state by default. Before feeding and metering, the force sensors are zeroed, and the metering pressure measured by all force sensors is Gi. The metering pressure measured by the force sensors before feeding into metering tank 1 is zero. This completes the effective installation of metering tank 1 and determines the tank's balanced state, thereby improving the accuracy of subsequent product metering process feeding stability detection.

[0038] Furthermore, a feed main pipe 10 is connected to the middle of the cover plate 2. A first clamping frame 17 is supported and connected to the surface of the feed main pipe 10 near the cover plate 2. The first clamping frame 17 is fixedly connected to the second frame plate 5. A feed control valve 15 is connected to the feed main pipe 10 to control the opening and closing status of the feed main pipe 10 and the product feed amount. The other end of the feed control valve 15 is connected to multiple feed branch pipes to facilitate metering of products with significant differences in type.

[0039] For example, the feed control main valve 15 is connected to a first feed branch pipe 11 and a second feed branch pipe 12 via a three-way valve. A first flow sensor 13 and a second flow sensor 14 are respectively connected to the first feed branch pipe 11 and the second feed branch pipe 12. The first feed branch pipe 11 is used for flow measurement of steam or waste gas, etc., and the first flow sensor 13 is preferably a vortex flow sensor. The second feed branch pipe 12 is used for flow measurement of oil or laboratory high-precision liquid, etc., and the second flow sensor 14 is preferably a turbine flow sensor.

[0040] Furthermore, a feed extension section 18 is fixedly connected between the feed main pipe 10 and the cover plate 2. The bottom of the metering tank 1 is set in an inverted cone shape and is fixedly connected with a pipe valve block 21. The other end of the pipe valve block 21 is connected to the discharge main pipe 20 for discharging the metered material. Several synchronous frames 23 are connected to the surface of the discharge main pipe 20 to provide stable support for the discharge main pipe 20. Further, refer to Figure 4The synchronous frame 23 includes a clamping block 231, an outer cylinder 232, and an inner cylinder 233. The clamping block 231 clamps the surface of the discharge manifold 20. The top of the outer cylinder 232 is fixedly connected to the non-clamping surface of the clamping block 231. The outer cylinder 232 is hollow inside and an alarm switch is installed in the middle of its inner top surface. The interior of the outer cylinder 232 is slidably connected to the outer surface of the inner cylinder 233. A slide bar 234 is fixedly connected to the inner cylinder 233. A sliding groove matching the slide bar 234 is opened on the inner side wall of the outer cylinder 232. In addition, a second support spring and a pressing block located inside the second support spring are fixedly connected to the top surface of the inner cylinder 233. The other end of the second support spring is fixed to the inner top surface of the outer cylinder 232. The pressing block and the alarm switch are located on the same straight line parallel to the sliding direction. The alarm switch is signal-connected to the data processor. When the alarm switch is triggered by the pressing block, the metering process will be paused.

[0041] When the external pump starts and feeds material into the metering tank 1 through the feed main pipe 10, the pipe valve block 21 closes, and the force sensor detects the metering pressure as Gi in real time. When the tank body descends due to internal feeding, the feed main pipe 10 remains stationary, and the feed extension section 18 is stretched. In addition, a discharge extension section 26 is fixedly connected above the surface of the discharge main pipe 20 away from the metering tank 1. The discharge extension section 26 is stretched, and the upper end of the discharge extension section 26 remains stationary while the lower end moves down synchronously. At the same time, the discharge main pipe 20 drives the synchronous frame 23 to move down, so as to ensure the operability of the metering tank 1 in the suspended support state for descent. Through the obvious descent of the metering tank 1, the user can intuitively know the feeding quality. When the feeding limit is reached and the aforementioned sensor does not detect the required feeding amount, the internal structure of the synchronous frame 23 directly triggers an alarm and shuts down the feeding metering process to ensure the safety of the tank.

[0042] refer to Figures 5-6 The cover plate 2 is fixedly connected to the inner tube 31 below the feeding telescopic part 18. The upper and lower ends of the inner tube 31 are connected to the outer tube 28 through bearings. The outer tube 28 and the inner tube 31 have several discharge holes 32 in the same position on their surfaces, and the gap between the outer tube 28 and the inner tube 31 is set as the discharge gap area 16. The top outer ring of the outer tube 28 is fixedly connected to the driven gear 29, which is meshed with the driving gear 30. The middle of the driving gear 30 is fixedly connected to the central shaft, and the central shaft is driven by the drive motor 19. By starting the drive motor 19, the feeding rate of the outer tube 28 and the inner tube 31 is finely adjusted to ensure the stability of the feeding.

[0043] like Figures 6-8 As shown, the discharge hole 32 on the surface of the outer tube 28 and the inner tube 31 overlaps, reaching the maximum feeding state in the tank. The metered product is discharged into the tank through the complete discharge hole 32, and the maximum feeding state is set as the default feeding state.

[0044] like Figure 9 As shown, the discharge holes 32 on the surfaces of the outer tube 28 and the inner tube 31 are blocked, achieving the minimum feeding state inside the tank. The metered product passes through the inner cavity of the inner tube 31, the discharge hole 32 of the inner tube 31, the discharge gap area 16, and the discharge hole 32 of the outer tube 28 in sequence, thereby performing product feeding. Since the discharge holes 32 are blocked, a product retention area is formed inside the outer tube 28, which allows the discharge volume of the metered product to be significantly reduced.

[0045] like Figure 10 As shown, the discharge holes 32 on the surfaces of the outer tube 28 and the inner tube 31 are partially blocked, achieving an adjustable feeding state inside the tank. The adjustable feeding state is between the maximum feeding state and the minimum feeding state. The intelligent adjustment of the feeding rate inside the tank is mainly achieved by driving the drive motor 19, thereby improving the stability of product feeding inside the tank.

[0046] Specifically, the data processor collects the metering pressure Gi during product metering and feeding in real time, first calculates the mean, and then calculates the dispersion, which can be either variance or standard deviation. Taking standard deviation as an example, the real-time metering pressure standard deviation α is obtained. G In the data processor, a first comparison value α1 and a second comparison value α2 are preset, where α1 < α2 and α1 is greater than 0; for example:

[0047] If 0≤α G When <α1, it indicates that the measured pressure has a small dispersion and the tank is relatively stable under stress, so the tank still maintains the maximum feeding state.

[0048] If α1≤α G When α < 2, it indicates that the measured pressure has a large dispersion and the force on the tank is relatively unstable. Therefore, the tank is adjusted to an adjustable feeding state. Specifically, the size of the local obstruction angle of the discharge port 32 is related to the standard deviation α of the real-time measurement pressure. G Negative correlation;

[0049] If α G When the pressure is ≥α2, it indicates that the measured pressure is severely volatile and the tank is seriously unstable. In this case, manual operation is required to stabilize the tank. The tank itself cannot maintain stability automatically. For example, the feeding can be paused for a period of time or an external support structure can be activated to stabilize the outer surface of the tank. Then, the tank should be adjusted to the minimum feeding state to ensure the stability of the tank before entering the adjustable feeding state. This will ensure the stability of the feeding process during the tank measurement process and improve the safety of the tank and the safety of product feeding.

[0050] In addition, during the discharge or distribution process after metering, a discharge control valve 22 is installed on the side of the discharge main pipe 20 near the pipe valve block 21 to control the discharge process; a discharge main pipe 25 is connected to the discharge extension part 26 at the location of the discharge main pipe 20, and a second clamping frame 27 is connected to the surface of the discharge main pipe 25. The other end of the discharge main pipe 25 is connected to a corresponding distribution pipe through a control valve for the distribution process after metering.

[0051] The end of the discharge main pipe 20 is also connected to a test valve 24, which is used in conjunction with various flow sensors and valve bodies to perform sealing tests on the pipeline connection to ensure the accuracy of the metering data.

[0052] Example 2: The method of using an intelligent detection device for product measurement is as follows:

[0053] S1: Perform the installation of metering tank 1 and the tank installation balance analysis. The installation needs to achieve a balanced state of the tank.

[0054] S2: Connect the pipeline and perform a leak test;

[0055] S3: Metering and feeding inside metering tank 1, intelligent analysis of the stability of product feeding inside the tank, and corresponding adjustment of feeding status;
