[0002] The fluidity of a fluid directly affects its operability, stability, and molding effect in practical applications, making it a crucial indicator for evaluating material properties. Traditional fluidity testing devices typically rely on manual operation. Specifically, they lack real-time monitoring and data acquisition capabilities, and data recording depends heavily on manual intervention. For example, in the commonly used "funnel method" test, operators need to visually judge the fluid outflow time, which is easily influenced by subjective judgment and environmental factors, resulting in low accuracy and consistency, and a tendency for omissions and errors. Furthermore, traditional fluidity testing devices usually only allow for fluidity testing at a specific height, failing to meet the testing needs of different heights. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The purpose of this invention is to provide a flowability testing device to solve the problems existing in the prior art and improve the accuracy, comprehensiveness and efficiency of the test.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1 As shown, this utility model provides a flowability testing device 100, including a test container 1, a height adjustment device 2, a flow detection device, and a control unit module 3. The test container 1 is mounted on the height adjustment device 2, and its bottom has an opening 101 for fluid outflow. The height adjustment device 2 can move the test container 1 in the height direction and maintain its position. The flow detection device can detect the flow rate of the fluid at the opening 101. The control unit module 3 includes a controller connected to the flow detection device. The test container 1 of this utility model can be height-adjusted via the height adjustment device 2, allowing fluid to flow downwards through the opening 101 from different heights. This facilitates flowability measurements at multiple heights, improving the comprehensiveness of the test. Simultaneously, the flow detection device can monitor the fluid flow rate in real time and accurately, sending the test data to the controller for recording and storage. The testing process requires no manual intervention, improving accuracy and efficiency.

[0028] In some embodiments, the height adjustment device 2 includes a support column 201, a movable component 202, a locking component 203, and a support platform 204. The support platform 204 is fixedly connected to the movable component 202, which is movable along the length of the support column 201. The locking component 203 is connected to the movable component 202 and locks the movable component 202 onto the support column 201. The support platform 204 has a vertically penetrating channel, with the opening 101 opposite to the channel. The structure is simple, the cost is low, it is easy to adjust, which helps to shorten the testing cycle and ensures testing efficiency.

[0029] In some embodiments, the moving member 202 and the locking member 203 are clamps, preferably vacuum clamps. The moving member 202 comprises two hinged semi-rings. The inner sidewalls of the two semi-rings can be cylindrical or conical. The materials of the two semi-rings are preferably stainless steel, hardened steel, rubber, or ceramic, which have a high coefficient of friction, enabling the inner sidewall of the moving member 202 to achieve frictional self-locking with the outer sidewall of the support column 201, ensuring that it will not easily slip when locked.

[0030] In some embodiments, scale lines are provided on the outer wall of the support column 201. The scale lines allow the test container 1 to be conveniently and accurately adjusted to a specific height, and ensure that the same height can be adjusted to a consistent height when multiple tests are performed at the same height. This ensures that the relative flow conditions remain unchanged during the test, reduces the influence of human eye error during height adjustment, and ensures the objectivity and repeatability of the test, thereby improving the accuracy and reliability of the test results.

[0031] In some embodiments, the height adjustment device 2 is an electric height adjustment device, which is more convenient to adjust than manual height adjustment. In a preferred embodiment, the electric height adjustment device is signal-connected to the control unit module 3, enabling height adjustment to be controlled by the control unit module 3. The electric height adjustment device can take various forms. For example, the electric height adjustment device includes an electric telescopic rod and a support platform 204. The output end of the electric telescopic rod is fixedly connected to the support platform 204, and the electric telescopic rod can drive the support platform 204 to rise and fall by extending and retracting in the vertical direction. The specific structure of the electric telescopic rod is prior art and will not be described in detail here. Another example is an electric height adjustment device including a support platform 204, a motor, a lead screw, and a guide rod. The lead screw and guide rod are both vertically arranged. An outer cylinder is provided on the support platform 204, and the outer cylinder is threadedly connected to the lead screw. The support platform 204 is slidably connected to the guide rod. The motor is connected to the lead screw and can drive the lead screw to rotate clockwise and counterclockwise around its own axis. By converting the rotation of the lead screw into linear motion of the support platform 204, the raising and lowering of the support platform 204 can be achieved, and the height control accuracy can be improved. The lead screw is preferably a ball screw or a trapezoidal lead screw. The control unit module 3 can control the electric height adjustment device via buttons, remote control, or touch screen.

[0032] In some embodiments, when the height adjustment device 2 is an electric height adjustment device, it is also equipped with components such as limit switches and position sensors. The limit switch is set on the electric telescopic rod and is communicatively connected to the control unit module 3. When the output end of the electric telescopic rod moves to a predetermined upper or lower limit, the control unit module 3 controls the electric telescopic rod to stop moving. The position sensor (e.g., an encoder or a Hall sensor) is communicatively connected to the control unit module 3. The position sensor monitors the position of the support platform 204 in real time. The control unit module 3 controls the height adjustment amount of the electric height adjustment device according to the received position signal of the support platform 204, so as to accurately control the lifting height and ensure the accuracy of height adjustment.

[0033] In some embodiments, an opening adjustment device is also included. The opening adjustment device is connected to the opening 101 of the test container 1. The opening adjustment device can adjust the size of the opening 101 and can be flexibly adjusted according to the flowability of different slurries, further improving the applicability of the device.

[0034] In some embodiments, the opening adjustment device includes a baffle, a slider, a lead screw, a guide rail, and an opening drive device. The baffle is fixedly connected to the slider, the slider is threadedly connected to the lead screw, and the slider is slidably connected to the guide rail. The opening drive device is connected to the lead screw and can drive the lead screw to rotate around its own axis. By rotating around its own axis, the lead screw can adjust the size of the area of ​​the opening blocked by the baffle. The axis of the lead screw and the center line of the guide rail along its length are perpendicular to each other and parallel to each other. The baffle is disposed below the opening 101 and can block the opening 101. When the lead screw rotates, it drives the baffle to move along the axis of the lead screw, thereby adjusting the degree of blocking of the opening 101 by the baffle, and thus adjusting the size of the opening 101.

[0035] In some embodiments, the lead screw of the opening adjustment device is a precision ball screw or trapezoidal screw, capable of adjustment within a small step range. The lead screw is made of wear-resistant material to ensure stability over long-term use. The guide rail is a linear guide rail made of wear-resistant material, such as hardened steel or aluminum alloy, ensuring the slider remains smooth and without deviation during sliding. The motor of the opening adjustment device is a stepper motor, which facilitates high-precision control.

[0036] In some embodiments, the opening adjustment device further includes a feedback system, which can be an encoder or a Hall sensor. The feedback system is used to detect the actual size of the opening. The feedback system is signal-connected to the control unit module 3, and the control unit module 3 is connected to the opening drive device. The control unit module 3 can compare the opening size detected by the feedback system with the preset opening size of the control unit module 3. When the opening size detected by the feedback system is smaller than the preset opening size of the control unit module 3, the control unit module 3 controls the opening drive device to move the baffle to increase the size of the opening 101; conversely, the control unit module 3 controls the opening drive device to move the baffle to decrease the size of the opening 101, so as to achieve the accuracy of opening adjustment.

[0037] In some embodiments, the opening adjustment device further includes a locking mechanism, which may be a locking bolt, a spring lock, etc. After the baffle position is adjusted, the locking mechanism locks the slider and the guide rail to prevent the size of the opening 101 from changing due to external vibration or interference.

[0038] It should be noted that the opening adjustment device may not include the opening drive device. The lead screw of the opening adjustment device can be rotated manually for manual adjustment.

[0039] In some embodiments, the control unit module 3 further includes a display, which is communicatively connected to the controller. The data collected by the flow detection device and the flowability indicators obtained by the controller can be displayed on the display, showing test results such as viscosity, flow time, flow rate, and flow curves for easy viewing.

[0040] In some embodiments, the control unit module 3 further includes an operation button, which is signal-connected to the control unit module 3. The operation button can be a physical switch button or a virtual button on the display, used for user interaction, enabling quick adjustment of test parameters such as density and temperature, meeting the requirements of simplicity and ease of use, and improving the level of automation and user experience.

[0041] In some embodiments, the controller includes a data acquisition unit, a data processing unit, and a data storage unit. The data acquisition unit is communicatively connected to the flow detection device, the data processing unit is communicatively connected to the data acquisition unit, and the data storage unit is signal-connected to the data processing unit. The data processing unit and the data storage unit are used for data processing and storage, respectively, eliminating the need for manual recording and calculation, which helps improve detection efficiency. Preferably, the data acquisition unit is communicatively connected to a display, and the controller includes a data export function capable of exporting test data.

[0042] In some embodiments, the system further includes a support frame 4 and an auxiliary support frame 5. Both the height adjustment device 2 and the auxiliary support frame 5 are fixedly connected to the support frame 4, and the auxiliary support frame 5 is fixedly connected to the height adjustment device 2. The flow detection device and the control unit module 3 are both mounted on the support frame 4. The height adjustment device 2 is fixedly connected to the support frame 4 itself and is also fixed to the support frame 4 through the auxiliary support frame 5, which helps to improve the stability of the installation.

[0043] In some embodiments, the flow detection device is a flow meter. The flow detection device is capable of recording the outflow time and flow rate of the fluid in real time.

[0044] In some embodiments, the support platform 204 is a rectangular platform. It also includes a support rod 6, to which the flow detection device and control unit module 3 are fixedly connected. The base of the support frame 4 is provided with fixing grooves for mounting the support rod 6 and support column 201, thereby ensuring that the support rod 6 and support column 201 are stably mounted on the base and preventing the test container 1 from shaking during testing. A collection device is disposed on the base, below the opening 101, for collecting the flowing slurry. The support frame 4 provides support for the collection device, support rod 6, support column 201, etc. The support column 201 and support rod 6 are vertically disposed on the two edges of the base.

[0045] In some embodiments, the flow detection device is positioned below the support platform 204, directly aligned with the opening 101.

[0046] This invention provides a flowability test for various fluids, including slurries of different viscosities and types, with wide applicability, and can meet the diverse needs of different fields for fluid flowability testing.

[0047] The working process of the fluidity testing device 100 of this utility model is as follows:

[0048] Preparation of test container 1: Install test container 1 onto support platform 204, ensuring that the fluid can flow downward from the opening 101 at the bottom of test container 1 and the channel of support platform 204; add the fluid to be tested into test container 1.

[0049] Height adjustment: Adjust the test container 1 to the required height using the height adjustment device 2. Adjust the test container 1 to the required height by observing the scale lines.

[0050] Test Startup: After the height of test container 1 is adjusted, the operator starts the flow detection device. The flow detection device begins recording the outflow time and flow rate of fluid through opening 101. The flow detection device collects data in real time and transmits it to the controller.

[0051] Data processing and display: The controller receives data from the flow detection device, calculates and processes it to obtain fluid flowability indicators. The processed data is displayed in real time on the screen, allowing users to directly view the test results.

[0052] End and Recording: The system will automatically stop the test once the fluid has completely flowed out. The test results will be stored in the controller's data storage unit for subsequent analysis and comparison. Users can also choose to export or print the test results. Specifically, after the flow detection device continuously sends flow data as 0 for a period of time, the controller will control the flow detection device to shut down, automatically stopping the test.

[0053] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
