Description

Technical Field

[0001] The invention belongs to the technical field of water reducing agent experiments, and in particular relates to an intelligent water reducing agent testing instrument. Background Art

[0002] When preparing cement-based grouting materials for semi-flexible mixtures, the slurry formula is required to be full, with little water exudation, no stratification and no precipitation. In order to achieve these properties, some admixtures are generally added during production to improve its performance, such as water reducers. Water reducers are concrete admixtures that can reduce the amount of mixing water while maintaining the slump of concrete basically unchanged. Most of them are anionic surfactants, such as lignin sulfonates, naphthalene sulfonate formaldehyde polymers, etc. After being added to the concrete mixture, they have a dispersing effect on cement particles, which can improve its workability, reduce unit water consumption, and improve the fluidity of the concrete mixture; or reduce unit cement consumption and save cement.

[0003] The amount of water reducer added is directly related to the working performance and strength development of cement-based grouting materials for semi-flexible mixtures. When more water reducer is added, the slurry may have greater fluidity, which may easily cause problems such as stratification and collapse, and will also have an adverse effect on the performance of the slurry. When less water reducer is added, the slurry may have lower fluidity, lower slurry density, increased water seepage, and lower impermeability. However, the prior art lacks experimental equipment for experiments on the optimal amount of water reducer to be added. When using additives, the approximate range of water reducer dosage given in the water reducer instruction manual is often used for addition and use, which may result in the problem of adding more or less water reducer.

[0004] Therefore, in view of the above technical problems, it is necessary to provide an intelligent water reducing agent testing instrument.

[0025] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0026] Example 1: Reference Figure 1-Figure 6 , an intelligent water reducing agent tester, including a base 1, and also including: a rotating frame 2, which is rotatably connected to the base 1 through a first rotating shaft 6; a rotating seat 301, which is equidistantly and rotatably connected to the rotating frame 2; an experimental cylinder 4, which is installed on the rotating seat 301; a spiral propulsion blade 401, which is fixedly connected to the inner wall of the experimental cylinder 4; a rotating shaft 7 is installed on the side of the base 1 and the rotating frame 2 away from the first rotating shaft 6, and two first hydraulic telescopic cylinders 303 are symmetrically rotatably connected between the two rotating shafts 7; a drawer groove is opened on the side of the base 1 close to the first rotating shaft 6; a drawer box 101 used in conjunction with the experimental cylinder 4 is equidistantly slidably connected in the drawer groove; a host 5 with a display function is installed on the base 1.

[0027] The bottom of the rotating frame 2 is fixedly connected to a first motor 3 via a first support plate. The output end of the first motor 3 is fixedly connected to the bottom of one of the rotating seats 301 . The multiple rotating seats 301 are connected via a first gear rack transmission assembly 302 .

[0028] In order to ensure the optimal fluidity of cement slurry while reducing water consumption, water reducers are usually used in the prior art to reduce water in cement slurry. However, the instructions for use of existing water reducers only give an approximate range of water reducer dosages. Therefore, when using the water reducer, it is necessary to experiment to determine the optimal dosage of the water reducer.

[0029] When experimenting on the optimal usage of water reducer, the experimenter first fixes the tester on the experimental workbench, and then makes three groups of standard cement slurries without water reducer for three fluidity tests corresponding to the tester, and records the experimental data as standard values. Then the experimenter mixes multiple portions of cement slurries with the same cement content and the same water consumption, and adds different amounts of water reducer of the same type to the multiple portions of cement slurries, and mixes them evenly. Then the experimenter can load the cement slurries with different amounts of water reducer into the multiple experimental tubes 4 on the tester respectively.

[0030] After the previous work is prepared, the first hydraulic telescopic cylinder 303 can be started through the host 5, and the first hydraulic telescopic cylinder 303 controls the rotating frame 2 to rotate to the specified inclination angle (that is, the angle at which the cement slurry can flow out freely), and then the cement slurry will flow out of the test tube 4 freely. When the cement slurry has good fluidity, more will flow out within the specified time. When the cement slurry does not flow well, less will flow out within the specified time. The outflowing cement slurry will flow into the corresponding drawer box 101. When the test is completed, the cement slurries stored in multiple drawer boxes 101 can be poured out and stored in separate beakers respectively. The weights are weighed and recorded and uploaded to the host 5. Then the host 5 will compare and analyze the standard values ​​obtained in advance from this experiment with the multiple values ​​of the experiment, so as to obtain a group that is closest to the standard value or the same as the standard value, and then the water reducer addition content in this group of cement slurries is the optimal addition content.

[0031] After a set of tests are completed, the cement slurry in the test tube 4 can be poured out, and the test tube 4 and the drawer box 101 can be cleaned. Then, the cement slurry can be proportioned again, and then the cement slurry with the same water reducer content as the last experiment can be loaded into multiple test tubes 4 on the tester respectively, and then the rotating frame 2 is controlled to rotate again, and the inclination angle of the test tube 4 is made smaller than the inclination angle of the last experiment (that is, after the test tube 4 is tilted, the cement slurry inside will not flow out freely), and then the first motor 3 can be started. The first motor 3 will drive the multiple test tubes 4 to rotate synchronously through the rotating seat 301 under the cooperation of the first gear rack transmission assembly 302, and then the test tube 4 will drive the spiral propulsion blade 401 to rotate, and then the cement slurry in the test tube 4 will be on the spiral propulsion blade 401. The cement slurry flows outwards under the push of the spiral propulsion blade 401 and falls into the corresponding drawer box 101. When the cement slurry has good fluidity, the cement slurry will partially flow back when the spiral propulsion blade 401 pushes it, so that less will flow out within the specified time. When the cement slurry does not flow well, the cement slurry will be thicker, so that more will flow out within the specified time. After the test is completed, the cement slurries stored in multiple drawer boxes 101 can be poured out and stored in separate beakers respectively. The weights are weighed and recorded and uploaded to the host 5. Then the host 5 compares and analyzes the standard values ​​obtained in advance from this experiment with the various values ​​of the experiment, so as to obtain a group that is closest to the standard value or the same as the standard value, and then the water reducer addition content in this group of cement slurries is the optimal addition content.

[0032] After the second set of tests are completed, the cement slurry in the test tube 4 can be poured out, and the test tube 4 and the drawer box 101 can be cleaned. Then, the cement slurry can be proportioned again, and then the cement slurry with different contents of water reducing agent added as in the previous test can be respectively filled into the multiple test tubes 4 on the tester, and then the rotating frame 2 is controlled to rotate again, and the inclination angle of the test tube 4 is made the same as that of the second test.

[0033] Then the first motor 3 can be started again, so that the test tube 4 drives the spiral propulsion blade 401 to rotate quickly for one circle, and the experimental rotation speed is the same as the experimental rotation speed of the standard value obtained in the previous experiment. Then, the cement slurry in the test tube 4 will flow out quickly under the promotion of the spiral propulsion blade 401, and fall into the corresponding drawer box 101. When the fluidity of the cement slurry is better, the distance the cement slurry flies out under the promotion of the spiral propulsion blade 401 will be farther. When the fluidity of the cement slurry is not good, the distance the cement slurry flies out under the promotion of the spiral propulsion blade 401 will be closer. After the test is completed, the values ​​of the flying distances of multiple groups of cement slurries are recorded and uploaded to the host 5. Then the host 5 will compare and analyze the standard value obtained in the previous experiment with the multiple values ​​of the experiment, so as to obtain a group that is closest to the standard value or the same as the standard value, and then the water reducer addition content in this group of cement slurries is the optimal addition content.

[0034] After the above three groups of experiments are completed, when two or more experimental results in one group are closest to or the same as the corresponding standard values, it can be concluded that the water reducer content in this group is the optimal water reducer addition content.

[0035] By using this tester to experiment on cement slurry with different water reducing agent contents, not only can the optimal addition content of the water reducing agent be accurately obtained, but the degree of automation is also relatively high, which effectively saves experimental time.

[0036] Example 2: Reference Figure 1-Figure 6 , an intelligent water reducing agent tester, which is basically the same as Example 1, and further, a rotating plate 102 is arranged on the base 1 near the opening of the drawer slot, and the end of the rotating plate 102 away from the rotating frame 2 is rotatably connected to the base 1 through the second rotating shaft 8, and the main machine 5 is installed on the rotating plate 102. By making the rotating plate 102 rotatably connected to the base 1, when not in use, the opening of the drawer box 101 can be covered to prevent dust from falling in. When in use, the rotating plate 102 can be opened. When the test tube 4 rotates rapidly to make the cement slurry fly out, the cement slurry flying far away can be blocked to prevent the flying cement slurry from falling to the ground and increasing the labor of the experimenter, and by setting the drawer slot to a specified length, when a group of cement slurry added with water reducing agent flies out of the test tube 4 and hits the rotating plate 102, it can be directly judged that the water reducing agent content in the group of cement slurry does not meet the standard, so that the flow performance of the water reducing agent under the content can be directly obtained.

[0037] Friction limit blocks 103 are symmetrically fixedly connected on both sides of one end of the rotating plate 102 close to the second rotating shaft 8, and a friction groove 104 used in conjunction with the friction limit block 103 is opened on the base 1. Through the coordinated use of the friction limit block 103 and the friction groove 104, when the rotating plate 102 is opened to block the cement slurry flying out of the experimental cylinder 4, the stability of the rotating plate 102 after opening can be improved, and the problem of the rotating plate 102 being closed may be avoided after the flying cement slurry hits the rotating plate 102.

[0038] Example 3: Reference Figure 1-Figure 6 , an intelligent water reducing agent tester, which is basically the same as Example 2, and further, a mounting groove is provided on the rotating seat 301, and the experimental tube 4 is located in the mounting groove of the rotating seat 301, and a plurality of limit strips 402 are fixedly connected to the outer wall of the experimental tube 4 at equal intervals, and a plurality of limit grooves used in conjunction with the limit strips 402 are provided on the rotating seat 301, and the limit grooves are connected to the mounting grooves, and the surface of the limit strips 402 is provided with anti-slip grooves. Through the setting of the mounting grooves and the limit strips 402, the experimental tube 4 can be detachably connected to the rotating seat 301, so that during the experiment, the experimental tube 4 can be flexibly taken and placed, which provides convenience for the experimenter to add cement slurry to the experimental tube 4 or clean the experimental tube 4, and by arranging anti-slip grooves on the limit strips 402, the stability of the experimental tube 4 installed on the rotating seat 301 can be guaranteed.

[0039] Example 4: Reference Figure 1-Figure 6 , an intelligent water reducing agent tester, which is basically the same as Example 3, and further includes two second hydraulic telescopic cylinders 201, which are symmetrically fixedly connected to the two sides of the rotating frame 2, and the two sides of the rotating frame 2 are symmetrically provided with rectangular openings 202, and a lifting plate 203 is provided on the rotating frame 2, and the two ends of the lifting plate 203 are respectively slidably connected in the rectangular opening 202 on the same side, and the telescopic end of the second hydraulic telescopic cylinder 201 is fixedly connected to the lifting plate 203, and a plurality of rotating rods 205 used in conjunction with the experimental cylinder 4 are rotatably connected to the lifting plate 203, and the lower side of the rotating rod 205 is fixedly connected to the mounting plate 207 through a connecting rod, and a pressure sensor 208 is embedded in the mounting plate 207.

[0040] The upper end of the lifting plate 203 is fixedly connected to the second motor 204 through the second support plate, and multiple rotating rods 205 are all upwardly penetrated through one end of the lifting plate 203 and are connected through the second gear rack transmission assembly 206. The output end of the second motor 204 is fixedly connected to a driving gear, and the driving gear is meshed with one of the gears in the second gear rack transmission assembly 206.

[0041] There are multiple mounting plates 207 equidistantly arranged around the circumference. By setting up multiple mounting plates 207, multiple pressure sensors 208 can be set on the rotating rod 205. After the multiple pressure sensors 208 have completed the detection, the multiple data can be averaged to ensure the accuracy of the data.

[0042] like Figure 1 As shown, after completing three tests on three cement slurries with different water-reducing agent contents, if the first test result shows that the performance of the cement slurry using the first water-reducing agent content is closest to the standard result, the second test result shows that the performance of the cement slurry using the second water-reducing agent content is closest to the standard result, and the third test result shows that the performance of the cement slurry using the third water-reducing agent content is closest to the standard result, then it will be difficult to judge. In order to solve this problem, this embodiment provides a fourth experimental test method: when the fourth experimental test method is needed, the main machine 5 can be used to control the second hydraulic telescopic cylinder 201 to drive the lifting plate 203 to move downward until the mounting plate 207 extends into the cement slurry to a height close to the middle, and then the main machine 5 can be used to control the second motor 204 to start, and the second The motor 204 will drive the driving gear to rotate, and the driving gear will drive the three rotating rods 205 to rotate synchronously through the second gear rack transmission assembly 206, and the rotating rod 205 will drive the mounting plate 207 to rotate through the connecting rod, and the mounting plate 207 will drive the pressure sensor 208 to rotate, and then the pressure sensor 208 can detect the resistance of the three cement slurries with different contents of water reducers to the mounting plate 207, and then the detected values ​​will be uploaded to the host 5. When doing this experiment, you can first do the experiment on the standard cement slurry, and then compare these three results with the standard value respectively. The group with the value closest to or the same as the standard value is the best group, so that it can be concluded that the cement slurry with this content of water reducer has the best performance, and thus the optimal addition content of this water reducer can be experimented out.

[0043] Among them, if in the first three experiments, there is a group with two experimental results that are closest to or the same as the corresponding standard values, it can be directly judged that the water reducer content is the optimal addition content, and there is no need to conduct this experiment again.

[0044] It should be noted that, before the experiment on the optimal addition content of the water reducing agent, the four experiments can be performed on the standard cement slurry without adding the water reducing agent, and the four detected standard values ​​are stored in the host 5 for subsequent experiments.

[0045] It should be noted that the components in the first gear rack transmission assembly 302 and the second gear rack transmission assembly 206 include multiple gears, and the multiple gears are connected by racks. The gear rack transmission is an existing technology well known to those skilled in the art and will not be elaborated on again.

[0046] Example 5: Reference Figure 1-Figure 6 , an intelligent water reducing agent tester, which is basically the same as Example 4, and further, the connecting rod used to connect the rotating rod 205 and the mounting plate 207 is an elastic rod, the upper end of the mounting plate 207 is fixedly connected to a first lever 209, and a support rod 2010 is fixedly connected to a position close to the experimental cylinder 4 on the rotating frame 2, and a second lever 2011 used in conjunction with the first lever 209 is fixedly connected to the side of the support rod 2010 close to the experimental cylinder 4.

[0047] When the rotating rod 205 drives the pressure sensor 208 to rotate in the cement slurry with the water reducing agent added through the mounting plate 207 and completes the detection of the flow shape of the cement slurry, the mounting plate 207 can be controlled to leave the cement slurry and keep the mounting plate 207 in the test tube 4. Then, the mounting plate 207 can be controlled to rotate again. During the rotation of the mounting plate 207, when the first lever 209 contacts the second lever 2011, the elastically arranged connecting rod will bend elastically under the obstruction of the second lever 2011. When the lever 2011 is separated, the connecting rod will shake under the action of its own elasticity and finally reset, so that the cement slurry adhered to the mounting plate 207 and the pressure sensor 208 can be shaken back into the experimental tube 4 under the action of the shaking of the connecting rod, so as to avoid the cement slurry adhered to the mounting plate 207 and the pressure sensor 208 dripping into the rotating seat 301 when the experimental tube 4 is removed from the rotating seat 301 and the cement slurry inside is poured out after the experiment is completed, so that the rotating seat 301 needs to be cleaned later, which effectively reduces the workload of the experimenters.

[0048] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0049] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
