[0033] In the related art, the measurement of the water absorption rate of powder materials is usually carried out manually, including weighing the filter paper after water absorption, and weighing the filter paper and the sample after adding the sample to the filter paper, and determining the water absorption rate of the sample by the mass of water absorbed within a certain period of time.
[0034] However, the measurement method of the water absorption rate in the related art has problems of being greatly affected by human factors and poor measurement accuracy.
[0035] In view of the above problems, an embodiment of the present application provides a detection device and a detection method for the water absorption rate of powder materials, which can avoid the influence of human factors on measurement and improve the measurement accuracy.
[0036] The technical solutions of the embodiments of the present application will be described in detail below with reference to the drawings.
[0037] Figure 1 It is a schematic structural diagram of the detection device for the water absorption rate of powder materials shown in the embodiments of the present application.
[0038] See Figure 1 , an embodiment of the present application provides a detection device for the water absorption rate of powder materials, including a first water tank 1, a second water tank 2, a pipeline 3, a weight detector 4, a microporous plate 5 and a controller 6.
[0039] The first water tank 1 and the second water tank 2 are connected through the pipeline 3. The microporous plate 5 is arranged at the liquid level in the second water tank 2, and the side wall of the microporous plate 5 is closely fitted with the side wall of the second water tank 2. The pipeline 3 has a first end 31 and a second end 32. The first end 31 of the pipeline 3 is located below the liquid level of the first water tank 1, and the pipeline 3 does not contact the first water tank 1. The second end 32 of the pipeline 3 is located below the liquid level of the second water tank 2.
[0040] The weight detector 4 is used to detect the weight of the first water tank 1. The controller 6 is communicatively connected with the weight detector 4. The controller 6 is used to receive the detection data of the weight detector 4. The weight detector 4 can transmit the real-time weight data of the detected first water tank 1 to the controller 6 through wired or wireless communication. The pipeline 3 does not contact the first water tank 1, so as to eliminate the influence of the pipeline 3 on the measurement, and make the weight detected by the weight detector 4 only the total weight of the first water tank 1 itself and the liquid therein.
[0041] The first water tank 1 and the second water tank 2 are connected through the pipeline 3. The first end 31 of the pipeline 3 is located below the liquid level of the first water tank 1, and the second end 32 of the pipeline 3 is located below the liquid level of the second water tank 2, so that the first water tank 1 and the second water tank 2 can achieve liquid level balance by using the siphon principle. Place a filter paper or a filter paper plus a sample on the microporous plate 5 in the second water tank 2. When the filter paper or the filter paper plus the sample absorbs the liquid in the second water tank 2 through the microporous plate 5, the liquid in the first water tank 1 can flow to the second water tank 2 through the pipeline 3, and the weight of the first water tank 1 will change. By detecting the weight change of the first water tank 1 by the weight detector 4, the water absorption of the filter paper or the filter paper plus the sample on the microporous plate 5 can be known. In this way, the detection process of the water absorption does not require manual operation, avoiding the influence of human factors on the measurement, improving the measurement accuracy, and reducing the error of repeated measurement in different tests.
[0042] Specifically, the liquid in the first water tank 1 and the second water tank 2 can be distilled water. The microplate 5 is arranged at the liquid level in the second water tank 2. The shape of the microplate 5 can match the shape of the second water tank 2. The side wall of the microplate 5 is in close fit with the side wall of the second water tank 2, which means the side wall of the microplate 5 is in contact with or has a small gap with the side wall of the second water tank 2. For example, it has a gap of 0 - 0.2 mm. The microplate 5 has a certain tension on the liquid in the second water tank 2. When the filter paper or the filter paper plus the sample on the microplate 5 absorbs water, the liquid level height in the second water tank 2 is kept basically unchanged, and the liquid in the first water tank 1 flows into the second water tank 2. Thus, the reduction in the weight of the first water tank 1 is the water absorption of the measured object.
[0043] Among them, the measured object is a filter paper or a filter paper plus a sample. During the test, the filter paper can be placed alone on the microplate 5 first to measure the water absorption of the filter paper, and then the filter paper with the sample is placed on the microplate 5 to measure the combined water absorption of the filter paper and the sample. According to the water absorption measured twice and the weight of the sample when it is dry, the water absorption rate of the sample can be calculated.
[0044] In some embodiments, the first water tank 1 is provided with an opening, and the first end 31 of the pipeline 3 extends into the first water tank 1 from the opening of the first water tank 1. Specifically, as Figure 1 shown, the upper end of the first water tank 1 is provided with an opening, and the first end 31 of the pipeline 3 extends from top to bottom into the liquid level below the opening of the first water tank 1 without contacting the first water tank 1 itself.
[0045] In some embodiments, the second end 32 of the pipeline 3 is connected to the side wall or the bottom wall of the second water tank 2. Specifically, as Figure 1 shown, the bottom wall of the second water tank 2 has an opening, and the second end 32 of the pipeline 3 is fixedly arranged at the opening of the bottom wall of the second water tank 2 and communicates with the second water tank 2 through this opening; the pipeline 3 extends upward from the first end 31 and then extends horizontally toward the second water tank 2, and then extends downward to the second end 32 to be connected to the second water tank 2. In other embodiments, the side wall of the second water tank 2 has an opening, and the second end 32 of the pipeline 3 is fixedly connected to the opening of the side wall of the second water tank 2 and communicates with the second water tank 2 through this opening. During the test, the second water tank 2 is fixed and does not contact the weight detector 4.
[0046] In some embodiments, as Figure 1 shown, the detection device for the water absorption rate of the powder material further includes a water pump 7. The pipeline 3 has a third end 33 communicated with the water pump 7, and the water pump 7 is used to inject or extract liquid into and / or out of the first water tank 1 and / or the second water tank 2.
[0047] Specifically, the water pump 7 can be communicatively connected to the controller 6, and the controller 6 controls the operation of the water pump 7. The three ends of the pipeline 3 are connected, and the water pump 7 can inject water into the first water tank 1 and / or the second water tank 2, and the water pump 7 can also pump water from the first water tank 1 and / or the second water tank 2 and operate according to actual needs.
[0048] In some embodiments, as Figure 1 shown, the pipeline 3 has a first branch 34, a second branch 35, and a third branch 36. Switch valves 8 are respectively provided on the first branch 34, the second branch 35, and the third branch 36, and the switch valves 8 are communicatively connected to the controller 6.
[0049] Specifically, the first end 31 is located on the first branch 34, the second end 32 is located on the second branch 35, and the third end 33 is located on the third branch 36. The controller 6 individually controls the opening and closing of the three switch valves 8, so as to separately control the on-off of the three branches. When performing detection, the switch valve 8 on the third branch 36 is closed, and the switch valves 8 on the first branch 34 and the second branch 35 are opened, so that the first water tank 1 and the second water tank 2 are communicated, and the water pump 7 is not communicated with the two water tanks. When adding water to or pumping water from the first water tank 1 and / or the second water tank 2, the switch valve 8 on the third branch 36 is opened, and the switch valve 8 on the first branch 34 and / or the second branch 35 is opened, so that the water pump 7 can inject water into or pump water from the first water tank 1 and the second water tank 2 simultaneously or separately. Among them, the switch valve 8 can be an electromagnetic valve.
[0050] In some embodiments, as Figure 1 shown, the detection device for the water absorption rate of the powder material further includes a moving mechanism 9, and the moving mechanism 9 is used to separate the first water tank 1 from the weight detector 4 and place the first water tank 1 on the weight detector 4.
[0051] Specifically, when detection is not required, the first water tank 1 is separated from the weight detector 4 through the moving mechanism 9 to protect the weight detector 4; when water absorption detection is required, the moving mechanism 9 moves the first water tank 1 to the weight detector 4.
[0052] In some embodiments, the moving mechanism 9 can move the first water tank 1 by means of left-right translation.
[0053] In some embodiments, as Figure 1 shown, the moving mechanism 9 is a lifting mechanism connected to the first water tank 1, and the lifting mechanism drives the first water tank 1 to rise or fall. When detection is not required, the lifting mechanism raises the first water tank 1 to separate it from the weight detector 4, and when detection is required, the lifting mechanism lowers the first water tank 1 to the bearing surface of the weight detector 4.
[0054] In some embodiments, the lifting mechanism includes a lead screw that can rotate relative to the first water tank 1. Specifically, the lifting of the first water tank 1 can be achieved by manually or electrically rotating the lead screw.
[0055] In some embodiments, as Figure 1 shown, the lifting mechanism includes a cam that can rotate relative to the first water tank 1. The cam abuts against the bottom surface of the first water tank 1, and the rotation of the cam can achieve the lifting of the first water tank 1. The cam can be driven to rotate by a manual knob or electrically.
[0056] In some embodiments, the lifting mechanism includes a cylinder or a hydraulic cylinder or a motor. The piston rod of the cylinder or the hydraulic cylinder is connected to the first water tank 1, so as to lift or lower the first water tank 1, or the motor drives the first water tank 1 to lift or lower through a screw or a lead screw.
[0057] In some embodiments, scale bars are provided on the side walls of the first water tank 1 and the second water tank 2. Before the test, the liquid levels in the first water tank 1 and the second water tank 2 can be made to be at their respective scale bars, so that the water volume reaches a predetermined value to ensure that the external conditions of each test remain unchanged. Specifically, the liquid levels can be made to be at the scale bars by sucking liquid from the two water tanks by a water pump 7.
[0058] In some embodiments, covers are provided at the upper ends of the first water tank 1 and the second water tank 2. The covers have a certain sealing property for the first water tank 1 and the second water tank 2, and can prevent the evaporation of water during the test from affecting the test accuracy. Among them, the cover on the first water tank 1 is the first cover 10, and the cover on the second water tank 2 is the second cover 20. The first cover 10 is provided with a hole for the pipeline 3 to pass through, which does not affect the lifting movement of the first water tank 1.
[0059] In some embodiments, the measuring range of the weight detector 4 is 0 g to 1500 g, and the detection accuracy is 0.1 g to 0.0001 g to meet the detection requirements and be applicable to the detection of various weight detectors 4, such as bentonite, montmorillonite, attapulgite, activated clay, clay, kaolin, flour, pulp, etc. The weight detector 4 can be an electronic balance, which has a very high accuracy.
[0060] In some embodiments, the pore size of the microplate 5 is 5 μm to 500 μm. A plurality of through holes are arranged in an array on the microplate 5, and the object to be measured absorbs the water in the second water tank 2 by the capillary action of the through holes. Preferably, the pore size of the microplate 5 is 50 μm to 300 μm to ensure stable water absorption and water absorption efficiency.
[0061] In some embodiments, the detection device for the water absorption rate of the powder material further includes a human-machine interaction device 30. The human-machine interaction device 30 is communicatively connected to the controller 6. The detection personnel can control the controller 6 through the human-machine interface on the human-machine interaction device 30 to control the water pump 7 or the moving mechanism 9 to work. The detection personnel can also input test data, such as the weights of the filter paper and the powder material, to the controller 6 through the human-machine interface, and can also perform a zeroing operation on the weight detector 4. The human-machine interface can also display the detected data and display the change of the water absorption amount in real time. The controller 6 can display a curve graph of the water absorption amount and time on the human-machine interface, for example Figure 2 and Figure 3 as shown. The human-machine interaction device 30 is an electronic device with a display screen, such as a monitor, a tablet, etc.
[0062] In some embodiments, the first water tank 1 is placed on the first tray 40, and the first tray 40 is placed on the weight detector 4. The moving mechanism 9 can be connected to the first tray 40 to move the first water tank 1 through the first tray 40. The second water tank 2 is placed on the second tray 50, and the second tray 50 is fixed.
[0063] In some embodiments, one side of the water pump 7 is communicated with the third end 33, and the other side of the water pump 7 is communicated with the water tank 60. The water pump 7 injects the water in the water tank 60 into the first water tank 1 and the second water tank 2, or pumps the water in the first water tank 1 and the second water tank 2 into the water tank 60.
[0064] The controller 6 generally has a memory and a processor. The processor can be a central processing unit (CPU), or can also be other general-purpose processors, digital signal processors (DSPs), application specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor can be a microprocessor or the processor can also be any conventional processor, etc. The controller 6 can be an industrial control computer, a single-chip microcomputer, etc.
[0065] The embodiment of the present application also provides a method for detecting the water absorption rate of the powder material, which can be implemented by using the detection device for the water absorption rate of the powder material described in the above embodiment. The method includes the following steps:
[0066] S1. Inject water into the first water tank 1 and the second water tank 2 to make the liquid levels between the first water tank 1 and the second water tank 2 balanced through the pipeline 3.
[0067] Among them, water can be injected into the first water tank 1 and the second water tank 2 through the water pump 7. The first water tank 1 and the second water tank 2 achieve liquid level balance according to the siphon principle. The liquid levels of the first water tank 1 and the second water tank 2 are adjusted by the water pump 7 and three on-off valves 8 so that they both reach their respective scale bar positions.
[0068] S2. Weigh the filter paper and the powder material sample separately and input the weights into the controller 6.
[0069] The weights of the filter paper and the powder material sample are weighed before detecting the water absorption amount, and the data is input into the controller 6 so that the controller 6 can directly calculate the water absorption rate value during the detection process. Among them, the powder material sample in this step is a dried sample, and the weight of the dried sample is 0.3 - 1.5 g, preferably about 1 g, and the weighing accuracy reaches 0.0001 g, denoted as m0.
[0070] S3. Place the filter paper on the microplate 5 in the second water tank 2, and detect the weight change of the first water tank 1 through the weight detector 4 to detect the mass of water absorbed by the filter paper, and record the mass of water absorbed by the filter paper as m2.
[0071] Specifically, before the weight detector 4 conducts the detection, first set the detection of the weight detector 4 to zero. Place the filter paper on the microplate 5 in the second water tank 2 to absorb water freely for no less than 30 minutes, and record the change in the water absorption amount of the filter paper in real time. As Figure 2 shown, it is a graph of the change in the water absorption amount of the filter paper, which can be generated by the controller and displayed through the human-machine interface. The real-time water absorption amount of the filter paper can be known through this graph.
[0072] Among them, the weight of water absorbed by the filter paper is the weight reduction of the liquid in the first water tank 1, that is, the weight reduction of the first water tank 1 detected by the weight detector 4.
[0073] S4. Place the filter paper with the powder material sample on the microplate 5 in the second water tank 2, and detect the weight change of the first water tank 1 through the weight detector 4 to detect the mass of water absorbed by the filter paper and the sample, denoted as m1.
[0074] Specifically, in this step, the test sample is placed on the filter paper, and then the filter paper and the test sample are placed on the microplate 5 together to absorb water freely for no less than 60 minutes, and the change in the water absorption amount is recorded in real time. Similarly, the weight reduction of the first water tank 1 detected by the weight detector 4 is the water absorption amount of the filter paper and the sample on it. As Figure 3 shown, it is a graph of the change in the common water absorption amount of the filter paper and the sample, which can be generated by the controller and displayed through the human-machine interface. The real-time water absorption amount of the filter paper and the sample can be known through this graph.
[0075] S5. The controller 6 calculates the water absorption rate of the powder material sample based on m1, m2, and the weight of the powder material sample. Specifically, the controller 6 calculates the water absorption rate X according to the following formula:
[0076] X = (m1 - m2) / m0 × 100%
[0077] Where m1 is the water absorption of the filter paper and the sample, m2 is the water absorption of the filter paper, and m0 is the weight of the sample when it is dry.
[0078] The detection device and detection method for the water absorption rate of a powder material provided by the embodiments of the present application have the following beneficial effects:
[0079] 1. The test process is simple, convenient to operate, and easy to conduct the test;
[0080] 2. There is no step of manually taking and weighing the weight after water absorption during the test process, and the error is very small;
[0081] 3. The online weight detector 4 has high precision and accuracy, which can greatly improve the detection accuracy of the water absorption rate;
[0082] 4. The detection method is simple, without conditions for human judgment, and it is very easy to realize automatic detection;
[0083] 5. It can display the change of the water absorption amount in real time, and can realize the real-time characterization of the material water absorption process;
[0084] 6. It is very easy to realize the whole-process data collection and curve display of the material water absorption test, providing a large amount of data support for subsequent data processing and analysis.
