Description

Technical Field

[0001] This utility model relates to a testing device, and more particularly to a viscosity testing device for the production of concrete water-reducing agents. Background Technology

[0002] In the production process of concrete water-reducing agents, precise testing of the viscosity is necessary to ensure consistent and stable product quality. Viscosity is an important indicator of the flow properties of a liquid, and for concrete water-reducing agents, its viscosity directly affects its dispersion effect and performance in concrete.

[0003] Traditional viscosity testing devices typically sample the water-reducing agent directly from the test cylinder. Since the water-reducing agent liquid may contain air bubbles, this can affect the accuracy of the measurement results. Traditional testing devices lack effective methods for removing air bubbles, leading to deviations in the test data. Secondly, traditional methods generally use fixed sampling points or sampling depths, making it difficult to ensure the uniformity and representativeness of each sample, which in turn affects the overall analysis results.

[0004] Therefore, it is necessary to design a viscosity testing device for concrete water-reducing agent production that can effectively remove air bubbles from the water-reducing agent and effectively sample the water-reducing agent at different depths, so as to ensure the accuracy of the test results. Summary of the Invention

[0005] The technical solution is as follows: A viscosity testing device for concrete water-reducing agent production includes a base plate, a placement frame mounted on the top surface of the base plate, through holes spaced apart on the top of the placement frame, a test cylinder placed in each through hole, a vibrator mounted inside the placement frame, the vibrator being positioned directly below the test cylinder, the vibrator helping to eliminate air bubbles in the water-reducing agent inside the test cylinder through vibration, vertical rods mounted side-by-side on the side walls of the test cylinder, an mounting plate mounted on the top of the vertical rods, multiple winding wheels mounted on the mounting plate, pull ropes wound around the winding wheels, a sampling ball connected to the end of the pull rope, the sampling ball extending into the test cylinder to take a sample.

[0006] Furthermore, a slide rod is slidably connected to the mounting plate, the lower end of the slide rod is connected to a stirring rod, and the upper end of the slide rod passes through the mounting plate and is connected to the output shaft of a motor that is detachably mounted on the mounting base.

[0007] Furthermore, an electric push rod is mounted on the mounting plate, and the piston rod of the electric push rod is connected to a cover plate for sealing the top opening of the test cylinder, wherein the slide rod rotates through the cover plate and the pull rope moves through the cover plate.

[0008] Furthermore, a cleaning box for cleaning the sampling ball and the stirring rod is installed on the top of the base plate.

[0009] Furthermore, a rubber sleeve is installed at the connection between the test tube and the placement frame.

[0010] Furthermore, a guide sleeve is provided at the sliding contact point between the slide rod and the mounting plate.

[0011] The beneficial effects of this utility model are as follows: 1. By using a vibrator set below the test cylinder, air bubbles in the water-reducing agent can be effectively removed while stirring, thereby improving the accuracy of viscosity measurement.

[0012] 2. By pulling a rope, the sampling ball is placed at different depths in the test cylinder, and the sampling ball is wound up by the winding wheel. In this way, samples of water-reducing agent at different depths inside the test cylinder are collected, thereby ensuring the accuracy of the test results. Attached Figure Description

Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings.

[0019] Example: A viscosity testing device for the production of concrete water-reducing agents, such as... Figures 1-4As shown, the device includes a base plate 1, a placement frame 2, a test cylinder 21, and a vibrator 3. A rectangular placement frame 2 is mounted on the top surface of the base plate 1. Three through holes are spaced apart on the top of the placement frame 2, and the test cylinder 21 is placed inside each through hole. A rubber sleeve 13 is installed at the connection between the test cylinder 21 and the placement frame 2. The rubber sleeve 13 helps improve the stability of the test cylinder 21 within the placement frame 2. A vibrator 3 is installed inside the placement frame 2, directly below the test cylinder 21. The vibrator 3 helps eliminate air bubbles in the water-reducing agent inside the test cylinder 21 through its vibration. Vertical rods 20 are mounted side-by-side on the side walls of the test cylinder 21, the number of which corresponds to the number of vertical rods on the test cylinder 21. The number of test cylinders 21 is consistent. The extended diameter of the test cylinder 21 perpendicular to the placement frame 2 is on the same straight line as the center point of the vertical rod 20. The top of the vertical rod 20 is equipped with a mounting plate 5. Multiple winding wheels 7 are set on the mounting plate 5. The winding wheels 7 are arranged around the center point of the circular part of the mounting plate 5. A pull rope 6 is wound around the winding wheel 7. The end of the pull rope 6 is connected to a sampling ball 61. The sampling ball 61 extends into the test cylinder 21 to take a sample. The depth of the pull rope 6 into the test cylinder 21 is controlled by the winding wheel 7, thereby controlling the depth of the sampling ball 61 in the test cylinder 21. This allows for effective sampling of the water-reducing agent at different depths in the test cylinder 21, thereby accurately detecting the viscosity of the water-reducing agent.

[0020] like Figure 3 As shown, a slide rod 12 is slidably connected to the mounting plate 5. A guide sleeve 10 is provided at the sliding contact point between the slide rod 12 and the mounting plate 5. The guide sleeve 10 helps to reduce the coefficient of friction between the slide rod 12 and the mounting plate 5. A stirring rod 11 is connected to the lower end of the slide rod 12. The upper end of the slide rod 12 passes through the mounting plate 5 and is connected to the output shaft of a motor 121 that is detachably mounted on the mounting base. The motor 121 is a servo motor.

[0021] like Figure 3 As shown, an electric push rod 8 is installed on the mounting plate 5. The piston rod of the electric push rod 8 is connected to a cover plate 9 for sealing the top opening of the test cylinder 21. The slide rod 12 rotates through the cover plate 9, and the pull rope 6 moves through the cover plate 9.

[0022] In use, the concrete water-reducing agent liquid to be tested is poured into the test cylinder 21. Then, the piston rod of the electric push rod 8 extends downward, thereby covering the top of the test cylinder 21 with the cover plate 9. At the same time, the stirring rod 11 is inserted into the test cylinder 21. Then, the motor 121 drives the slide rod 12 to rotate, thereby driving the stirring rod 11 to rotate, thus fully stirring the concrete water-reducing agent in the test cylinder 21. Meanwhile, the vibrator 3 vibrates at the bottom of the test cylinder 21, thereby removing the foam in the water-reducing agent in the test cylinder 21. During sampling, the piston rod of the electric push rod 8 retracts upward, thereby moving the cover plate 9 away from the test cylinder 21. The cover plate 9 also drives the stirring rod 11 and the slide rod 12 to move upward. Then, by rotating the winding wheel 7, the pull rope 6 is wound up, thereby pulling the sampling ball 61 out of the water-reducing agent in the test cylinder 21, thus obtaining water-reducing agent samples at different depths in the test cylinder 21, thereby performing viscosity testing on the water-reducing agent in the test cylinder 21.

[0023] like Figure 1 As shown, a cleaning box 4 for cleaning the sampling ball 61 and the stirring rod 11 is installed on the top of the base plate 1. The cleaning box 4 and the placement frame 2 are arranged side by side on the top surface of the base plate 1.

[0024] After the test is completed, rotate the vertical rod 20 180 degrees to rotate the stirring rod 11 and the sampling ball 61 to the top of the cleaning tank 4. Then release the winding wheel 7 and the electric push rod 8 to send the stirring rod 11 and the sampling ball 61 into the cleaning tank 4 for cleaning.
