Description

Technical Field

[0001] This application relates to the field of test devices, and particularly to an intelligent Engler viscometer. Background Art

[0002] An Engler viscometer is an instrument used to measure the Engler viscosity of petroleum products. The Engler viscosity of a liquid is the ratio of the time (in seconds) it takes for the liquid to flow out of the Engler viscometer under certain temperature and volume conditions to the time (in seconds) it takes for distilled water to flow out at 20°C.

[0003] The Engler viscometer includes a frame. There are two sets of containers for placing test solutions on the frame. Each container consists of an inner layer and an outer layer. The outer layer is filled with water, and the inner layer is filled with the test solution. There is an outlet at the bottom of the inner layer, and a graduated measuring cup is placed below the outlet. The container is provided with a top cover, on which a thermometer and a wooden plug rod are provided. The wooden plug at the bottom of the wooden plug rod can be inserted into the outlet, and the thermometer is used to measure the temperature of the test solution. A heating device for heating the container is provided on the frame, which can maintain the water in the container at a preset temperature.

[0004] During the test, the test solutions are respectively added to the inner layers of the two sets of containers. When the thermometer detects that the temperature of the test solution reaches the required value, start the stopwatch while pulling out the wooden plug rod. The test solution flows through the outlet into the graduated measuring cup. Stop the stopwatch when observing that the test solution reaches the preset scale to obtain the flow times of the two sets of test solutions. Then, calculate the Engler viscosity of the test solution based on the above two sets of parallel data.

[0005] However, currently, the temperature, time, measuring cup scale, etc. in the Engler viscometer test all need to be observed and manually operated by the experimenter, which may lead to inaccurate judgment of the test results due to human errors. Utility Model Content

[0006] In order to improve the test accuracy, this application provides an intelligent Engler viscometer.

[0007] An intelligent Engler viscometer provided by this application adopts the following technical solutions:

[0008] An intelligent Engler viscometer includes a frame. A measuring cup placement groove is provided on the frame. Two graduated measuring cups are provided in the measuring cup placement groove. Two cameras are provided on one side of the frame facing the graduated measuring cups. The cameras are arranged in one-to-one correspondence with the graduated measuring cups, and the cameras are connected to a control module;

[0009] The control module is electrically connected to a timer;

[0010] When the test solution in the graduated measuring cup reaches the first scale, the control module starts the timer;

[0011] When the test solution in the graduated measuring cup reaches the second scale, the control module stops the timer.

[0012] The second scale is higher than the second scale.

[0013] By adopting the above technical solution, the camera photographs the graduated measuring cup, and the control module makes a comparison based on the picture. When it is determined that the test solution reaches the first scale, the timer starts timing. When the test solution reaches the second scale, the timer stops timing. Therefore, there is no need for manual operation, and the test timing can be automatically achieved, avoiding errors caused by human operation and improving the data accuracy.

[0014] Furthermore, a light-shielding plate is arranged in the measuring cup placement groove, and the light-shielding plate is located between the two graduated measuring cups and the two cameras.

[0015] By adopting the above technical solution, the light-shielding plate enables the camera to only photograph the corresponding graduated measuring cup, so as to prevent other items from affecting the control module's recognition of the scale.

[0016] Furthermore, a container is also arranged on the rack. The container includes an inner container and an outer container arranged coaxially. An outlet is arranged at the bottom of the inner container, and the outlet extends into the measuring cup placement groove. A top cover is arranged on the container, and an electronic thermometer inserted into the inner container is arranged on the top cover.

[0018] Furthermore, the electronic thermometer is connected to the control module, and the control module is connected to a first sound alarm and a second sound alarm.

[0019] By adopting the above technical solution, the control module receives the temperature data. When the temperature of the test solution reaches the test temperature, the control module controls the first sound alarm to emit a sound alarm to prompt the staff about the temperature state of the test solution. When the temperature of the test solution is abnormal, the control module controls the second sound alarm to emit a sound alarm, facilitating the staff to check in time and improving the work efficiency.

[0020] Furthermore, a wooden plug rod is inserted into the center of the top cover. A wooden plug is fixed at the bottom end of the wooden plug rod, and the wooden plug is inserted into the outlet. A driving mechanism for driving the wooden plug rod to move up and down is arranged on the top cover, and the driving mechanism is connected to the control module.

[0021] By adopting the above technical solution, the control module can automatically control the up and down movement of the wooden plug rod through the driving mechanism, realizing automatic control when liquid discharge is required, reducing the liquid flow delay caused by manual operation, and improving the accuracy of the detection data.

[0022] Further, the driving mechanism is an electric telescopic rod, and the output end of the electric telescopic rod is detachably connected to the cork rod.

[0023] By adopting the above technical solution, the electric telescopic rod is convenient for realizing automatic control and has simple operation.

[0024] Further, a fixing plate is fixed at the output end of the electric telescopic rod. A vertically penetrating fixing hole is formed in the fixing plate. A fixing rod penetrating the fixing hole horizontally is threadedly connected to the fixing plate. A transverse through hole is formed at the top end of the cork rod. The cork rod is inserted into the fixing hole, and the fixing rod penetrates through the through hole and is tightened with the fixing plate.

[0025] By adopting the above technical solution, before adding the test solution, it is necessary to first plug the cork into the liquid outlet and open the top cover to prepare for adding the test solution. Therefore, the cork rod needs to be detachably connected to the determining mechanism for convenient use.

[0026] Further, a bracket is further included. The bracket includes an inner cylinder and an outer cylinder. The outer cylinder is sleeved outside the inner cylinder. A scale is arranged on the side wall of the inner cylinder. A fixing bolt is threadedly connected to the bottom end of the outer cylinder. The fixing bolt is tightened and abuts against the side wall of the inner cylinder. A fixing table is arranged at the top of the outer cylinder. The fixing table includes a platform and vertical plates respectively connected to both sides of the platform. One of the vertical plates is rotatably connected to the side wall of the outer cylinder through a horizontal rotating shaft. A knob is threadedly connected to the other vertical plate. The knob is threadedly connected to the side wall of the outer cylinder, and the knob is coaxially arranged with the horizontal rotating shaft. The camera is fixed on the platform.

[0027] By adopting the above technical solution, when it is necessary to adjust the height of the camera, the outer cylinder and the inner cylinder are adjusted relative to each other and locked. When it is necessary to adjust the angle of the camera, the fixing table is rotated and locked.

[0028] Further, a display screen and a power switch are arranged on the frame.

[0029] By adopting the above technical solution, it is convenient to display temperature data, etc., and the power switch is convenient for one-key operation.

[0030] Further, the control module is connected to an electronic device.

[0031] By adopting the above technical solution, the electronic device can receive the test data sent by the control module and can perform further calculation, statistics, storage, printing, etc.

Detailed Description of the Embodiment

[0041] The following further elaborates on the present application in conjunction with the attached Figures 1-4 for a more detailed description.

[0042] An embodiment of the present application discloses an intelligent Engler viscometer. Refer toFigure 1 , Figure 2 and Figure 3 , the intelligent Engler viscometer includes a frame 1, and a power switch 20 is arranged on the frame 1.

[0043] A heating base 2 is arranged on the upper part of the frame 1. Two container placement grooves 11 are arranged on the heating base 2, and a container 3 is arranged in each container placement groove 11. A measuring cup placement groove 12 is arranged on the lower part of the frame 1. Two circular cup pads 4 are arranged at the bottom of the measuring cup placement groove 12. A graduated measuring cup 5 is placed on the cup pads 4, and each graduated measuring cup 5 is arranged corresponding to each container 3 one by one.

[0044] Among them, the bottom of the container placement groove 11 is communicated with the measuring cup placement groove 12. The container 3 includes an inner container 31 and an outer container 32 arranged coaxially. Water is contained in the outer container 32, and a test solution is contained in the inner container 31. The heating base 2 heats the water in the outer container 32 to heat the test solution in the inner container 31. When predicting water, the water temperature is made slightly higher than the test temperature by about 0.5 - 1.5 °C to prepare for accelerating the gradual heating process of the test solution.

[0045] An outlet 33 is arranged at the bottom of the inner container 31. The outlet 33 extends into the measuring cup placement groove 12 through the container placement groove 11. The top of the graduated measuring cup 5 is sleeved outside the outlet 33. When the test solution flows out from the outlet 33, it directly enters the graduated measuring cup 5.

[0046] A top cover 6 is arranged on the top of the container 3. An electronic thermometer 7 is arranged on the top cover 6. The electronic thermometer 7 is connected to a control module 8. The control module 8 is connected with a first sound alarm 9 and a second sound alarm 10. The electronic thermometer 7 detects the temperature of the test solution in the inner container 31. When the difference between the temperature of the test solution and the water temperature does not exceed a preset value, the temperature of the test solution reaches the test requirement. The preset value is 25 °C + 0.1 °C. The control module 8 controls the first sound alarm 9 to give a sound alarm to prompt that the temperature of the test solution reaches the requirement. When the temperature of the test solution is higher than the water temperature and the difference exceeds the preset value, the control module 8 controls the second sound alarm 10 to give a sound alarm to prompt that the temperature of the test solution is abnormal, which is convenient for the staff to check in time. Among them, the sounds emitted by the first sound alarm 9 and the second sound alarm 10 are different, which is convenient for the staff to distinguish the two different situations.

[0047] In order to facilitate directly observing the temperature of the test solution, a display screen 13 is arranged on the frame 1. The control module 8 displays the temperature value detected by the electronic thermometer 7 on the display screen 13.

[0048] A wooden plug rod 14 is also inserted in the center of the top cover 6. A wooden plug 15 is fixed to the bottom end of the wooden plug rod 14, and the wooden plug 15 can be inserted into the liquid outlet 33. A driving mechanism 16 is also fixed on the top cover 6. The driving mechanism 16 is connected to the control module 8, and the driving mechanism 16 drives the wooden plug rod 14 to move up and down. When the temperature of the test solution reaches the test requirement and is maintained for 2 minutes, the control module 8 controls the driving mechanism 16 to raise the wooden plug rod 14, so that the wooden plug 15 is lifted from the liquid outlet 33, and the test solution flows into the graduated measuring cup 5.

[0049] Among them, the Engler viscosity of the test solution is calculated as Ev = tr / tw

[0050] In the formula: Ev—the Engler degree of the test solution at temperature T;

[0051] tr—the outflow time (s) of the test solution at temperature T for a certain time;

[0052] tw—the water value of the Engler viscometer, that is, the time (s) for water to flow out the same volume of 50 mL at 25°C; it can be directly measured, or it can be converted from the outflow time of 200 mL of water at 20°C to the outflow time of 50 mL of water at 25°C. The other conversion coefficient F is 0.224, then tw = K_20×F = K_20×0.224.

[0053] As can be seen from the above, before conducting the test solution test, it is necessary to obtain the water value of the Engler viscometer under the same test conditions, that is, first use water as the test solution for a test, and then conduct the test on the test solution to be tested. In order to unify the standard, the lifting position of the wooden plug 15 should be the same as that when measuring the water value.

[0054] In this application, the driving mechanism 16 can be an electric telescopic rod 161, and the output end of the electric telescopic rod 161 is detachably connected to the wooden plug rod 14. During the test solution test and when measuring the water value, the length of the output end of the electric telescopic rod 161 extending out is equal, so that the lifting position of the wooden plug 15 is kept consistent. When adding the test solution to the inner container 31, the wooden plug rod 14 is disassembled from the electric telescopic rod 161, the top cover 6 is removed, the wooden plug rod 14 is inserted into the liquid outlet 33, and then the test solution is added; when the liquid addition is completed, the top cover 6 is covered, and the wooden plug rod 14 is fixed to the electric telescopic rod 161.

[0055] Further, a fixing plate 162 is fixed to the output end of the electric telescopic rod 161. A vertically penetrating fixing hole 163 is opened on the fixing plate 162. A fixing rod 164 passing through the fixing hole 163 is threadedly connected to the fixing plate 162. A transverse perforation 165 is opened at the top end of the wooden plug rod 14. When fixing, the wooden plug rod 14 passes through the fixing hole 163, and the fixing rod 164 passes through the perforation 165 and is tightened with the fixing plate 162, so as to fix the electric telescopic rod 161 and the wooden plug rod 14.

[0056] Refer to Figure 1 andFigure 4 On one side of the frame 1, a camera 17 is also provided. The camera 17 is fixed on a bracket 18, and the height of the bracket 18 is adjustable.

[0057] The bracket 18 includes an inner cylinder 181 and an outer cylinder 182. The outer cylinder 182 is sleeved outside the inner cylinder 181, and a scale is provided on the side wall of the inner cylinder 181. When the outer cylinder 182 is lifted, the scale can be exposed to facilitate adjusting the height of the outer cylinder 182 according to the scale. A fixing bolt 183 is threadedly connected to the side wall at the bottom end of the outer cylinder 182. The fixing bolt 183 can be tightened and abutted against the side wall of the inner cylinder 181 so as to relatively fix the outer cylinder 182 to the inner cylinder 181. A fixing platform 184 is provided at the top of the outer cylinder 182. The fixing platform 184 includes a platform 1841 and vertical plates 1842 respectively connected to both sides of the first fixing plate 162. One of the vertical plates 1842 is rotatably connected to the side wall of the outer cylinder 182 through a horizontal rotating shaft, and a knob 185 is threadedly connected to the other vertical plate 1842. The knob 185 is threadedly connected to the side wall of the outer cylinder 182, and the knob 185 is coaxially arranged with the horizontal rotating shaft. The camera 17 is fixed on the platform 1841. When it is necessary to adjust the shooting angle of the camera 17, loosen the knob 185, rotate the fixing platform 184, and then tighten the knob 185.

[0058] Before the experiment, adjust the heights of the two cameras 17 so that the cameras 17 are directly facing the graduated measuring cup 5 for shooting. When the control module 8 makes the driving mechanism 16 drive the cork rod 14 to rise, the control module 8 controls the camera 17 to start shooting. The camera 17 sends the captured pictures to the control module 8, and a timer 22 is connected to the control module 8. The control module 8 compares the pictures with the preset pictures. The preset pictures include pictures of the test solution reaching the first scale and pictures of the test solution reaching the second scale. When it is determined by comparison that the test solution reaches the first scale, the control module 8 controls the timer 22 to start timing; when it is determined by comparison that the test solution reaches the second scale, the control module 8 controls the timer 22 to stop timing.

[0059] Among them, the second scale is greater than the first scale. In this application, the first scale can be 50 mL, and the second scale can be 100 mL. Therefore, the control module 8 can obtain the outflow time of the test solution with a volume of 50 mL flowing out.

[0060] Furthermore, a light-shielding plate 19 is also provided in the measuring cup placement groove 12. The light-shielding plate 19 is located between the two graduated measuring cups 5 and the two cameras 17 to prevent the camera 17 from capturing multiple graduated test tubes and affecting the analysis result.

[0061] Further, the control module 8 is connected to an electronic device 21, which can be a terminal such as a PC, a mobile phone, or a tablet. The control module 8 can transmit temperature data, timing data, etc. Both the control module 8 and the electronic device 21 can be configured with calculation programs to calculate the Engler viscosity of the test solution according to the above formula. Moreover, the electronic device 21 can also view current test data and historical test data.

[0062] The implementation principle of an intelligent Engler viscometer according to an embodiment of the present application is as follows: Turn on the power switch 20, and the system performs self-check. If the self-check is normal, basic parameters such as the temperature of the heating base 2 and the rising height of the cork rod 14 are entered, and the test steps are continued. If the self-check is abnormal, the cause is found.

[0063] Next, open the top cover 6, add water into the outer container 32, and insert the cork 15 into the liquid outlet 33. Start the heating base 2 to make the water temperature slightly higher than the test temperature.

[0064] Place a clean and dry graduated measuring cup 5 on the coaster 4 below the liquid outlet 33, and adjust the bracket 18 so that the camera 17 is directly facing the graduated measuring cup 5.

[0065] Then add the test solution into the inner container 31, cover the top cover 6, and fix the cork rod 14 to the electric telescopic rod 161. The electronic thermometer 7 detects the temperature of the test solution. When the temperature of the test solution reaches the test temperature, the control module 8 controls the first sound alarm 9 to give an audible alarm. After maintaining for 2 minutes, the control module 8 controls the output end of the electric telescopic rod 161 to extend, moving the cork rod 14 upward horizontally, and the cork 15 is pulled out from the liquid outlet 33, and the test solution flows into the graduated measuring cup 5 through the liquid outlet 33.

[0066] The camera 17 takes real-time pictures of the graduated measuring cup 5 and sends the taken pictures to the control module 8. The control module 8 determines the scale lines in the graduated measuring cup 5 by comparison. When the test solution reaches the first scale, the control module 8 starts the timer 22; when the test solution reaches the second scale, the control module 8 stops the timer 22.

[0067] Therefore, the electronic device 21 obtains the test data and completes the test.

[0068] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
