Description

Technical Field

[0001] The invention belongs to the technical field of chemical material performance testing, and in particular relates to a device and method for automatically measuring the gelation time of a chemical slurry. Background Art

[0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art.

[0003] In the research and development and engineering applications of chemical grouting materials (such as epoxy resins, polyurethanes, and cement-based grouts), gel time measurement is a key indicator for evaluating the material's reaction kinetics. Traditional methods rely on the manual pour-cup method, where an operator manually pours the mixed grout repeatedly into a container and visually observes changes in the grout's fluidity to determine the gel endpoint.

[0004] The traditional inverted cup method for testing the setting time of chemical slurries requires repeated manual pouring of the mixture and observation of the flow state. This method has the following drawbacks: the pouring angle, speed, and resting time are subject to subjective influence by the operator; the human eye cannot accurately judge the gelation state; and the lack of a unified standard for experimental data makes the comparability of results between different laboratories difficult. During the inverted cup method, human factors can easily affect the experimental results, resulting in a lack of standardization, accuracy, and comparability of experimental data and results.

[0005] While some automated measurement devices have emerged in the prior art, they still suffer from numerous drawbacks, hindering accurate time measurement. For example, an existing automated test device for the gel time of a cement-water-glass two-liquid slurry exhibits shear-thinning behavior. Because most chemical slurries exhibit shear-thinning behavior, the gel time of the uniformly stirred chemical slurry differs significantly from that measured using the traditional inverted cup method. Furthermore, chemical slurries are often non-transparent, and adhesion to optical components can affect gel time determination. Summary of the Invention

[0006] To overcome the above-mentioned deficiencies of the prior art, the present invention provides an automatic device and method for measuring the gelation time of a chemical slurry, which can effectively solve the problems of lack of standardization, accuracy and comparability of experimental data and results caused by manual inverted cup test.

DETAILED DESCRIPTION

[0036] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.

[0037] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0038] In the absence of conflict, the embodiments of the present invention and the features thereof may be combined with each other.

[0039] like Figure 1 、 Figure 2As shown, this embodiment discloses an automatic measuring device for the gelation time of a chemical slurry, comprising a base 1, on which a servo drive motor 5 is fixedly provided, the output shaft of the servo drive motor 5 being rotatably connected to a mud tank 2, a baffle 4 being slidably provided in the mud tank 2, the baffle 4 being fixedly connected to a closed-loop steel wire rope 8, the closed-loop steel wire rope 8 being wound around a rotating shaft 7, the rotating shaft 7 being fixedly connected to a baffle drive motor 6, the baffle drive motor 6 rotating to drive the rotating shaft 7 to rotate, and then the baffle 4 is pulled to slide through the closed-loop steel wire rope 8;

[0040] A control system is integrated inside the base 1, and the control system is connected to the servo drive motor 5 and the baffle drive motor 6 respectively; the control system is configured to: control the servo drive motor 5 and the baffle drive motor 6 to drive the mud tank 2 to tilt alternately to both sides at a set angle, and determine whether the slurry has completed coagulation based on the torque change rate during the static time for a set number of consecutive times.

[0041] In this embodiment, if Figure 1 As shown, the base 1 comprises a base plate 101 and a column 102 vertically fixed to the base plate 101. A servo drive motor 5 is fixed to the top of the column 102. The base plate serves as a basic support, providing a stable mechanical foundation and ensuring the secure installation of all components of the device. The column 102 is vertically fixed to the base plate 101, and the servo drive motor 5 is mounted on the top. This ensures that the motor and the axis of the mud tank are aligned to prevent deviation during tilting operation. The column also raises the servo drive motor to the appropriate height to facilitate the vertical tilting movement of the mud tank.

[0042] A display window 103 and multiple function buttons 104 are provided on the base plate 101. A control system is integrated within the base plate 101 and is connected to the display window 103, the function buttons 104, the servo drive motor 5, the baffle drive motor 6, and the torque sensor. Specifically, the control system receives the output signal of the torque sensor in real time, calculates the torque change rate based on the output signal, transmits the torque change rate to the display window 103 for display, and records the torque change of the servo drive motor 5 to facilitate further determination of the slurry coagulation time and the slurry coagulation state. The function buttons are used to control the experimental process and set parameters (such as the tilt angle, the rest time, and the slurry coagulation determination threshold). The control system receives input commands from the function buttons 104, analyzes them, and generates control signals to drive the servo drive motor 5 and the baffle drive motor 6. The servo drive motor 5 is used to tilt the mud tank 2 at a preset angle and frequency, and the baffle drive motor 6 is used to drive the baffle 4 to separate and mix the A and B slurries.

[0043] Furthermore, the function buttons 104 include a button for controlling the start of the experiment, a button for adjusting the tilt angle of the mud tank and the static time, a button for setting the slurry coagulation determination threshold, and a button for retrieving experimental process data. Direction keys, a confirmation key, and numeric keys may also be provided. The function buttons can also be adaptively adjusted according to the specific experiment and are not specifically limited.

[0044] In some implementations, the control system is implemented using a single-chip microcomputer, and the model of the single-chip microcomputer can be flexibly selected according to actual conditions, and this embodiment does not make any specific limitations.

[0045] In this embodiment, if Figure 1 、 2 As shown, the mud tank 2 is rotatably connected to the output shaft of the servo drive motor 5. The servo drive motor 5 rotates to drive the mud tank 2 to rotate in the vertical direction. The control system controls the rotation angle of the servo drive motor and thus controls the tilt angle of the mud tank, and controls the cyclic tilt of the mud tank according to the preset frequency. In this embodiment, the tilt angle of the mud tank is , the rest time is 1 second, and the cycle tilt direction is alternating The mud tank and servo drive motor are used to simulate the standardized operation of the manual inverted cup method, eliminating human errors and ensuring the repeatability and accuracy of the test.

[0046] The mud tank 2 is a cylindrical tank with a retractable cover 201 mounted on the sidewall along a horizontal axis. One side of the cover 201 is hinged to the tank body, while the other side is provided with an elastic sealing strip. Multiple buckles 202 are evenly fixed to the side with the elastic sealing strip. When closed and the buckles 202 are locked, the cover 201 forms a liquid-tight barrier between the tank body and the tank body. The buckles 202 include a buckle seat and a rotatable locking tongue. The buckle seat is fixed to the sidewall of the tank, while the rotatable locking tongue is fixed to one edge of the cover 201. The buckles 202 lock the cover 201 to the tank body, ensuring the tank's tightness and preventing leakage of liquid from the tank during cyclic tilting, which could affect the accuracy of the experiment. When the cover is unfolded, it is convenient to fill the slurry and clean the tank. When closed, the elastic sealing strip ensures that there is no leakage during the measurement process. The cover design replaces the traditional top or side filling port to solve the problems of difficult filling and high residue when the slurry is viscous. After the cover is unfolded, a large opening is formed, which can be directly poured or cleaned, and can achieve rapid filling of high-viscosity slurry.

[0047] Two sliding guide rails 3 are fixedly provided on the inner top of the mud tank 2 with a certain distance between them. The sliding guide rails 3 are cylindrical structures and are parallel to the length side of the tank body. Their two ends are respectively fixed on the circular side walls at both ends of the mud tank 2 to limit the movement trajectory of the baffle 4.

[0048] A first pulley assembly and a second pulley assembly are fixedly installed at both ends of the outer side of the mud tank 2, forming a baffle traction system with a closed-loop steel wire rope 8. The first pulley assembly includes a first pulley 301 and a second pulley 302 symmetrically arranged on the outer upper portion of the circular side walls at both ends, and the first pulley 301 and the second pulley 302 are both a certain distance away from the upper edge of the circular side walls. The second pulley assembly includes a third pulley 303 and a fourth pulley 304 symmetrically arranged on the outer lower edge of the circular side walls at both ends. The closed-loop steel wire rope 8 starts from the first pulley 301, passes around the first pulley 301 and passes through the circular side wall at that end, passes through the interior of the mud tank and the baffle fixing 401, passes through the other circular side wall and passes around the second pulley 302, then goes downward and passes through the fourth pulley 304 and the third pulley 303 in sequence, returning to the first pulley 301, forming a closed loop path. The horizontal steel wire rope between the fourth pulley 304 and the third pulley 303 is located outside the mud tank.

[0049] Furthermore, a rubber ring is provided at the point where the closed-loop steel wire rope 8 penetrates the circular side wall of the mud tank to ensure the sealing of the mud tank body and prevent the slurry from leaking.

[0050] A baffle drive motor 6 is fixedly mounted on one side of the bottom of the mud tank, along with a rotating shaft 7. The output shaft of the baffle drive motor 6 is fixedly connected to the rotating shaft 7, and rotation of the baffle drive motor 6 drives the rotating shaft 7. A horizontal wire rope, wound between the fourth pulley 304 and the third pulley 303, is wound around the rotating shaft 7. As the rotating shaft 7 rotates, a closed-loop wire rope 8 is retracted and extended, which in turn translates into lateral sliding of the baffle 4. The baffle drive motor controls the sliding direction of the baffle by driving the rotating shaft in forward and reverse rotation to retract and extend the closed-loop wire rope.

[0051] Furthermore, the baffle drive motor 6 is secured to one side of the mud tank's curved outer wall via a vertical fixing rod 601, and the rotating shaft 7 is secured to the other side of the mud tank's curved outer wall via a bent fixing rod 701. The fixing rods secure the baffle drive motor 6 and rotating shaft 7 to the mud tank's outer wall, preventing loosening of the components when the mud tank is tilted, ensuring transmission stability, and avoiding interference.

[0052] In some embodiments, the mud tank is made of a transparent, corrosion-resistant material and has an anti-stick coating on the inside.

[0053] In this embodiment, if Figure 3 、 Figure 4As shown, the baffle 4 includes a connected fixing part 401 and a fan-shaped baffle 402, and a plurality of pores 403 are provided on the upper part of the baffle to allow the slurry to flow and stir the slurry; guide rings 404 are respectively provided at the upper and lower ends of the fixing part 401, and the two sliding guide rails 3 pass through the guide rings 404 at the upper and lower ends respectively, and the baffle 4 can slide laterally along the sliding guide rails 3 inside the mud tank through the guide rings 404; and the baffle 4 is fixedly connected to the closed-loop wire rope 8 through the fixing part 401, and the horizontal wire rope between the first pulley 301 and the second pulley 302 passes through the fixing part 401 to fix the fixing part 401 and the closed-loop wire rope 8, thereby realizing the fixed connection between the baffle 4 and the closed-loop wire rope 8. Slurry A and slurry B are isolated by the lower part of the fan-shaped baffle 402, and its pores 403 allow the slurry to flow when the baffle 4 slides horizontally to one end, so that slurry A and slurry B are mixed; the guide ring 404 cooperates with the sliding guide rail 3 to reduce friction resistance and ensure smooth horizontal sliding of the baffle 4.

[0054] It should be noted that the guide ring 404 is adapted to the sliding guide rail 3 fixedly provided on the top of the mud tank.

[0055] In some embodiments, the apertures 403 are configured as triangular apertures.

[0056] In this embodiment, a torque sensor is provided on the servo drive motor 5 to monitor the torque changes of the mud tank in real time. The torque sensor is integrated into the output shaft end of the servo drive motor and is electrically connected to the control system to transmit torque information to the control system.

[0057] Example 2

[0058] This embodiment discloses a method for automatically measuring the gelation time of a chemical slurry, comprising:

[0059] S1: Experiment initialization and parameter setting;

[0060] Open the retractable cover 201 on the side wall of the mud tank, clean the mud tank, and check the operating status of the closed-loop wire rope 8, the sliding guide rail 3, and the first and second pulley sets to ensure that there is no jamming. Set the experimental parameters through the function button 104 on the bottom plate 101. For example, the first setting angle is the mud tank tilt angle. , the static setting time is 1 second, the second setting angle is the mud tank rotation (That is, the fixed tilt angle of the mud tank 2 is , the cyclic tilt direction is alternating ), set the number of static times to 3 times, and set the threshold to 5% of the initial torque value. The experimental parameters can be flexibly adjusted according to actual conditions and are not specifically limited in this embodiment.

[0061] S2: Pour the two slurries into the two sides of the mud tank respectively, and separate the two slurries by a baffle;

[0062] Chemical slurry A and slurry B are poured into both sides of the slurry tank respectively, the cover plate 201 is closed, and the baffle 4 is located in the center of the tank body to isolate chemical slurry A and slurry B.

[0063] S3: The control system controls the baffle drive motor to rotate, which drives the rotating shaft to retract and extend the closed-loop wire rope. The closed-loop wire rope pulls the baffle toward one end of the mud tank to mix the two slurries. The control system controls the servo drive motor to rotate, which drives the mud tank to tilt to one side at a first set angle and stand still for a set time.

[0064] The process by which the baffle drive motor 6 pulls the baffle 4 is as follows: the baffle 4 is located in the center of the slurry tank 2 and is fixed to the closed-loop wire rope 8 via a fixing member 401, separating slurry A and slurry B on either side of the tank. The closed-loop wire rope 8 is in a slack state on the rotating shaft 7, and the baffle drive motor 6 is not started. The control system drives the motor forward (with a clockwise rotation angle being considered positive) based on the input command, driving the rotating shaft 7 to rotate clockwise. The rotating shaft 7 is wound around the horizontal wire rope between the fourth pulley 304 and the third pulley 303, and the closed-loop wire rope 8 is tightened along the closed-loop path. The closed-loop wire rope 8 pulls the baffle 4 to slide leftward, and the baffle 4 moves leftward along the sliding guide rail 3. The apertures 403 on the baffle 4 allow the slurry to flow. When the baffle 4 moves completely to the left tank wall, slurries A and B are completely in contact and mixed. After the mud tank 2 tilts to a first set angle and remains stationary for a set time, the control system controls the baffle drive motor 6 to reverse, causing the shaft 7 to rotate counterclockwise. The shaft 7 releases the wound closed-loop wire rope 8, which then pulls in the opposite direction, pulling the baffle 4 to slide rightward along the sliding guide rail 3 to return the baffle 4 to its initial position. The control system then controls the baffle drive motor 6 to continue to reverse, causing the closed-loop wire rope 8 to pull the baffle 4 to slide rightward until the baffle 4 has completely moved to the right tank wall. The servo drive motor 5 then drives the mud tank 2 to rotate to a second set angle, allowing it to remain stationary for a set time, and then repeating the above operation, i.e., driving the mud tank 2 to tilt alternately to the first set angle on both sides.

[0065] In some embodiments, the control system uses an existing PID algorithm to control the sequence, rotation direction, and interval time of the servo drive motor and the baffle drive motor, thereby automatically measuring the gel time of the chemical slurry.

[0066] In some embodiments, the first set angle is , the static setting time is 1 second, the second setting angle is .

[0067] S4: After standing still for a set time, the baffle drive motor drives the rotating shaft to retract and release the closed-loop wire rope, and the closed-loop wire rope pulls the baffle to move to the other end of the mud tank; the servo drive motor drives the mud tank to rotate to the other side by a second set angle and stands still for a set time;

[0068] The servo drive motor 5 drives the mud tank 2 to tilt to one side by a first set angle and to rotate to the other side by a second set angle, that is, to make the mud tank 2 tilt to one side and be parallel to the horizontal direction. Tilt, with the baffle 4 at the top, after standing for 1 second, the servo drive motor 5 drives the mud tank 2 to rotate , that is, the mud tank 2 is in the horizontal direction to the other side Tilt, and the end where the baffle 4 is located is still on the top.

[0069] S5: driving the mud tank to tilt alternately to both sides at a first set angle according to a preset frequency, and collecting the torque signal of the servo drive motor in real time through the torque sensor and transmitting it to the control system;

[0070] The preset frequency is to drive the mud tank to tilt alternately upward and downward every time it is left to stand for a set period of time.

[0071] S6: Based on the torque signal, the torque change rate is obtained, and the control system determines whether the torque change rate is less than the set threshold value within the set number of static times. If so, it is determined that the slurry has completed coagulation. If not, the alternating tilting is continued.

[0072] The control system automatically records the total time from the start of slurry mixing to the determination that the slurry has completed coagulation, automatically determines the total gelation time of the chemical slurry, and outputs the slurry coagulation time determined by the control system, which is displayed through display window 103. The control system also saves a curve showing the relationship between the torque change rate and time, which facilitates the experimenter to verify and determine the accuracy of the experimental results.

Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.

Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without any creative work are still within the scope of protection of the present invention.
