Description

[0001] The present application claims priority to the Chinese Patent Application No. 202423054760.9, filed on December 11, 2024, and entitled "Particle size detection device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present disclosure relates to the technical field of particle size detection, for example, to a particle size detection device. BACKGROUND

[0003] In modern industry and daily life, particle products (such as cement, medicine powder, coal powder, and catalysts, etc.) are widely used, and their performance largely depends on the particle size distribution. Accurate particle size detection is crucial for ensuring product quality and optimizing production processes.

[0004] In the related art, the electric sensitive zone method is a commonly used particle size detection method. This method measures the particle size by monitoring the resistance change caused by the particle passing through a specific pore size. The workflow usually includes sampling from the production line, preparing the sample to be tested, using electrical principles to obtain the pulse voltage signal generated by the particle, and converting it into the corresponding particle equivalent size for counting and statistics.

[0005] Although the above method has good sensitivity and accuracy, the design of the particle size detection device based on the electric sensitive zone method has certain limitations. For example, the particle size detection device can usually only cover the particle size within a certain specific interval. When facing a wide range of particle sizes, it may be necessary to replace devices of different specifications or adjust the settings, which not only increases the operation complexity, but also reduces the work efficiency. In addition, using a single detection test tube cannot cover a wide range of particle sizes at the same time.

[0050] In order to enable a more detailed understanding of the features and technical content of the embodiments of the present disclosure, the implementation of the embodiments of the present disclosure is described in detail below, and the accompanying drawings are used for reference only and do not limit the embodiments of the present disclosure. In the following technical description, in order to facilitate explanation, through multiple details, a sufficient understanding of the disclosed embodiments is provided. However, one or more embodiments can still be implemented without these details. In other cases, well-known structures and devices can be simplified to facilitate the drawings.

[0051] The terms "first", "second", and the like in the specification and claims of the embodiments of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so as to implement the embodiments of the present disclosure described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion.

[0052] Unless otherwise specified, the term "a plurality of" means two or more.

[0053] In the embodiments of the present disclosure, the character " / " represents an "or" relationship between the objects before and after it. For example, A / B represents: A or B.

[0054] The term "and / or" is a description of the association between objects, which means that there can be three relationships. For example, A and / or B, which means: A or B, or, A and B, three relationships.

[0055] The term "corresponding" can refer to an association or binding relationship, A corresponding to B means that there is an association or binding relationship between A and B.

[0056] In combination Figure 1 And Figure 2 As shown, the embodiments of the present disclosure provide a particle size detection device, which includes a mounting base 1, a plurality of test tubes 2 and a plurality of fasteners 3. The mounting base 1 is provided with a plurality of test tube mounting holes 11, the test tubes 2 correspond to the test tube mounting holes 11 one by one, and the fasteners 3 correspond to the test tubes 2 one by one, that is, the number of test tube mounting holes 11, test tubes 2 and fasteners 3 is the same. For example, the number of test tube mounting holes 11, test tubes 2 and fasteners 3 is 3.

[0057] The detection test tube 2 is provided with a detection hole 21 for particles to pass through on the side away from the tube opening. The solution to be detected can enter the detection test tube 2 through the detection hole 21. The detection holes 21 of the respective detection test tubes 2 have different hole diameters. It can be understood that, because the detection holes 21 of the respective detection test tubes 2 have different hole diameters, the respective detection test tubes 2 also have different particle size measurement ranges. For example, for two detection test tubes 2 with different hole diameters of the detection holes 21, the detection test tube 2 with a smaller hole diameter of the detection hole 21 has a size measurement range of 1 to 400 microns, and the detection test tube 2 with a larger hole diameter of the detection hole 21 has a size measurement range of 1 to 800 microns. In this case, the user can select appropriate combinations of detection test tubes 2 according to actual needs for detection, and flexibly cover a wide range of particle sizes.

[0058] The tube opening part of each detection test tube 2 is arranged in the corresponding test tube mounting hole 11 through a fastener 3. The form of the fastener 3 can be determined according to actual design needs. For example, the fastener 3 is a sealing nut, the fastener 3 is sleeved on the tube opening part of the test tube, and the fastener 3 is connected with the test tube mounting hole 11 through threads. Of course, the fastener 3 can also adopt other forms. For example, the fastener 3 is a component capable of being deformed, the fastener 3 is arranged in the test tube mounting hole 11, and the tube opening part of the test tube is fixed in the test tube mounting hole 11 by deforming to apply pressure to the tube opening part of the test tube.

[0059] Figure 3 is an equivalent schematic view of the particle size detection device provided by the embodiment of the present disclosure, which is combined with Figure 3 As shown in the figure, when using the particle size detection device, it is necessary to immerse the detection hole 21 of the detection test tube 2 in the solution to be detected, so that the solution to be detected can enter the detection test tube 2 through the detection hole 21. Specifically, the container 100 can be used to hold the solution to be detected. When using the particle size detection device, the detection test tube 2 needs to be placed inside the container 100, so that the detection hole 21 of the detection test tube 2 is immersed in the solution to be detected. Here, the solution to be detected can be injected into the container 100 through the water injection pipe 300.

[0060] The particle size detection device provided by the embodiment of the present disclosure adopts a plurality of detection test tubes with detection holes of different hole diameters. Each detection test tube has a different particle size measurement range. The user can select appropriate combinations of detection test tubes according to actual needs for detection, and flexibly cover a wide range of particle sizes. The particle size detection device can better adapt to different types and sizes of particle samples, and enhance the applicability and practicality of the particle size detection device. Moreover, because a single particle size detection device is configured with a plurality of detection test tubes with detection holes of different hole diameters, a wider range of particle size information can be obtained in a single operation without the need to replace the device or adjust the settings of the device, thereby simplifying the operation process and improving the work efficiency of particle size detection.

[0061] In some embodiments, the electrode rod that needs to be inserted into the inside of the detection test tube 2 is defined as the inner electrode rod 4. The test tube mounting hole 11 is provided through the mounting base 1, and the inner electrode rod 4 of each test tube mounting hole 11 passes through the test tube mounting hole 11, so that the probe of the inner electrode rod 4 is located inside the corresponding detection test tube 2.

[0062] In some embodiments, the particle size detection device further comprises a plurality of inner electrode rods 4, which correspond to the test tube mounting holes 11. The inner electrode rod 4 is provided through the corresponding test tube mounting hole 11, and the probe of the inner electrode rod 4 is located inside the detection test tube 2 corresponding to the test tube mounting hole 11. For example, the number of test tube mounting holes 11 and inner electrode rods 4 is 3, and one inner electrode rod 4 is arranged in each test tube mounting hole 11.

[0063] In some embodiments, in combination with Figures 1 to 5 As shown in FIG. 1, the electrode rod that needs to be arranged outside the detection test tube 2 is defined as the outer electrode rod 5. The mounting base 1 is provided with an outer electrode hole 12 for the outer electrode rod 5 to pass through.

[0064] In some embodiments, in combination with Figure 4 and Figure 5 As shown in FIG. 1, the particle size detection device further comprises an outer electrode rod 5 provided through the outer electrode hole 12.

[0065] In combination with Figure 3 As shown in FIG. 1, when using the particle size detection device, it is necessary to immerse the detection hole 21 of the detection test tube 2 and the outer electrode hole 12 into the solution to be detected, so that the solution to be detected can enter the detection test tube 2 through the detection hole 21. When the solution enters the detection test tube 2 through the detection hole 21 and contacts the probe of the inner electrode rod 4, the resistance between the probe of the inner electrode rod 4 and the probe of the outer electrode rod 5 changes instantaneously, generating a potential pulse signal. The size and number of potential pulse signals are proportional to the size and number of particles, and the particle size data of the solution can be obtained based on the potential pulse signal.

[0066] In some embodiments, a plurality of test tube mounting holes 11 are arranged around the outer electrode hole 12, so that a plurality of detection test tubes 2 can be arranged around the outer electrode rod 5. Since each detection test tube 2 is provided with an inner electrode rod 4, all the inner electrode rods 4 are located around the same outer electrode, which can ensure that the electric field distribution of all detection channels is more uniform, which helps to reduce measurement errors caused by electrode position differences and improve the consistency and reliability of data. In addition, the ring layout can more effectively utilize the limited space, making the entire detection device more compact.

[0067] In some embodiments, each detection hole 21 of each detection test tube 2 is oriented towards the axis of the outer electrode hole 12. All detection holes 21 of all detection test tubes 2 are oriented towards the axis of the outer electrode hole 12, i.e. the probes of all detection holes 21 of all detection test tubes 2 are oriented towards the same direction of the outer electrode rod 5, which can ensure that the electric field environment in which the particles pass through the detection holes 21 is consistent. This consistency helps to reduce measurement errors caused by uneven electric field distribution, thereby improving the accuracy of particle size detection. Orienting the detection holes 21 towards the axis of the outer electrode hole 12 can maximize the working principle of the electric sensitive zone method. When the particles pass through the detection holes 21, they will more directly affect the resistance change between the inner and outer electrodes, producing clearer and more stable pulse signals, which helps to improve the quality of the signals and the signal-to-noise ratio.

[0068] In some embodiments, in combination with Figures 1 to 7 As shown, the mounting base 1 is provided with a plurality of water outlet holes 13, and the water outlet holes 13 correspond one-to-one with the test tube mounting holes 11. It can be understood that, in the case that the water outlet holes 13 communicate with the corresponding test tube mounting holes 11, the detection test tubes 2 corresponding to the water outlet holes 13 and the test tube mounting holes 11 also achieve communication, and the solution in the detection test tubes 2 can be discharged through the water outlet holes 13.

[0069] In some embodiments, in combination with Figures 1 to 7 As shown, the particle size detection device further comprises a plurality of water outlet pipes 6, and the water outlet pipes 6 correspond one-to-one with the water outlet holes 13. That is, the number of water outlet pipes 6 and water outlet holes 13 is the same, and each water outlet pipe 6 corresponds to one water outlet hole 13. Each water outlet pipe 6 is arranged in the corresponding water outlet hole 13 and extends into the inside of the detection test tube 2 corresponding to the test tube mounting hole 11 which communicates with the water outlet hole 13. The solution in the detection test tube 2 can be discharged through the water outlet pipe 6 extending into the inside of the detection test tube 2.

[0070] In some embodiments, in combination with Figures 1 to 7 As shown, the mounting base 1 is provided with a plurality of air holes 14, and the air holes 14 are used to communicate with the vacuum suction module 7. The air holes 14 correspond one-to-one with the test tube mounting holes 11, that is, the number of air holes 14 and test tube mounting holes 11 is the same, and each air hole 14 corresponds to one test tube mounting hole 11, and each air hole 14 communicates with the corresponding test tube mounting hole 11. The vacuum suction module 7 can adjust the air pressure in the detection test tube 2 through the air hole 14.

[0071] In some embodiments, in combination with Figures 1 to 7As shown, the particle size detection device further comprises a vacuum suction module 7, which is in communication with each air hole 14. It can be understood that when the air hole 14 is in communication with the corresponding test tube installation hole 11, the test tube 2 corresponding to the air hole 14 and the test tube installation hole 11 is also in communication. The vacuum suction module 7 can adjust the air pressure in the test tube 2 through the air hole 14, so as to control the flow rate and volume of the solution flowing into the test tube 2.

[0072] In some embodiments, the combination of Figures 1 to 8 As shown, the vacuum suction module 7 comprises a peristaltic pump 71, a box 72, a valve 73, a first air pipe 74 and a second air pipe 75. Specifically, the peristaltic pump 71 is connected to the box 72 through the first air pipe 74, the box 72 is in communication with the air hole 14 on the installation base 1 through the second air pipe 75, and the valve 73 is arranged on the second air pipe 75. The peristaltic pump 71 can extract or deliver gas from or to the box 72 through the first air pipe 74, so as to change the air pressure in the box 72. Since the box 72 is in communication with the corresponding test tube 2 through the second air pipe 75 and the air hole 14, when the air pressure in the box 72 changes, the air pressure in the test tube 2 will also change accordingly. The change of the air pressure in the test tube 2 directly affects the flow rate and volume of the solution flowing into the test tube 2. Therefore, by adjusting the air pressure of the test tube 2, the flow rate and volume of the solution can be accurately controlled.

[0073] In the embodiments of the present disclosure, the valve 73 can be a hose valve. The hose valve (also known as a pinch valve, pipe clamp valve or squeeze valve) is a valve 73 that controls fluid flow by squeezing a hose. It is usually composed of a movable mechanical component (such as a piston, slider or roller) and a section of elastic hose.

[0074] In some embodiments, as Figure 8 As shown, the vacuum suction module 7 further comprises an air pressure gauge 76 arranged in the box 72. The air pressure gauge 76 is used to detect the air pressure in the box 72, which helps to accurately control and adjust the air pressure, ensuring the stability and accuracy of the detection process.

[0075] In some embodiments, as Figure 8 As shown, the vacuum suction module 7 further comprises a waste tank 77. The outlet of the peristaltic pump 71 and the outlet of the valve 73 are both provided with the waste tank 77.

[0076] In the embodiments of the present disclosure, the vacuum suction module 7 can accurately control the flow rate, and the liquid flow during the detection process is more stable, thereby significantly improving the stability and consistency of the detection signal. The vacuum suction module 7 (including the peristaltic pump 71, the box 72, the valve 73, the first air pipe 74, and the second air pipe 75) is used to adjust the air pressure in the detection test tube 2, so as to accurately control the flow rate and volume of the solution. This vacuum suction mode ensures the uniform dispersion of the solution and improves the accuracy of the detection. By adjusting the air pressure, the flow rate of the solution can be accurately controlled to ensure the stability of the liquid flow during the detection process. This design not only ensures the stability of the detection process, but also improves the reliability and repeatability of the measurement results, thereby providing good working conditions for accurate particle size detection.

[0077] In some embodiments, as shown in Figure 9 , the particle size detection device further comprises a stirring module 8 with a stirring paddle 81, and the stirring module 8 is arranged adjacent to the mounting base 1. The stirring module 8 is used to uniformly stir the detection solution to ensure that the particles in the solution are more uniformly distributed, thereby improving the accuracy and reliability of the detection results.

[0078] In some embodiments, as shown in Figure 9 , the stirring module 8 further comprises a motor 82 and a coupling 83, and the motor 82 is connected to the stirring paddle 81 through the coupling 83. The motor 82 drives the stirring paddle 81 to rotate, thereby realizing the uniform stirring of the detection solution by the stirring paddle 81.

[0079] In some embodiments, as shown in Figure 9 , the particle size detection device further comprises a bearing plate 9, and the mounting base 1 and the stirring module 8 are arranged on the bearing plate 9. The bearing plate 9 integrates the mounting base 1 and the stirring module 8 to form a whole unit, thereby simplifying the overall structure of the device.

[0080] In some embodiments, the bearing plate 9 is provided with two hollow areas, and the mounting base 1 and the stirring module 8 are arranged in the corresponding hollow areas and connected with the bearing plate 9. Through the design of the hollow areas, the space can be effectively utilized.

[0081] In some embodiments, as shown in Figure 9 , the particle size detection device further comprises a connecting plate 10, and the motor 82 of the stirring module 8 is arranged on the connecting plate 10, and the connecting plate 10 is arranged in the hollow area.

[0082] In some embodiments, in combination with Figure 10 and Figure 11 , the particle size detection device further comprises a control module 200. The control module 200 can control the particle size detection device to detect the particle size of the solution.

[0083] It can be understood that the control module 200 can be in communication connection with the inner electrode rod 4, the outer electrode rod 5, the vacuum suction module 7 and the stirring module 8. Specifically, the control module 200 is connected with the inner electrode, the outer electrode, the peristaltic pump 71, the valve 73, the air pressure gauge 76 and the motor 82.

[0084] In the embodiments of the present disclosure, the particle size detection device adopts a modular design, which not only simplifies the maintenance process of the device, but also reduces the maintenance cost. When a certain module fails, only the corresponding functional module needs to be checked to quickly find the problem and replace it. For example, if a certain detection test tube 2 or air pressure adjustment module fails, the module can be directly replaced without the need for large-scale disassembly and repair of the entire system. Since each module can be replaced independently, this reduces the downtime of the entire machine caused by the failure of a single component, thereby improving the overall service life of the device.

[0085] In combination Figure 12 As shown, the control module 200 includes a processor 201 and a memory 202. Optionally, the control module 200 can also include a communication interface 203 and a bus 204. The processor 201, the communication interface 203 and the memory 202 can communicate with each other through the bus 204. The communication interface 203 can be used for information transmission. The processor 201 can call the logical instructions in the memory 202 to execute the particle size detection method.

[0086] In addition, the logical instructions in the memory 202 described above can be implemented in the form of a software function unit and sold or used as an independent product when used, which can be stored in a computer readable storage medium.

[0087] The memory 202 as a computer readable storage medium can be used to store software programs, computer executable programs, such as program instructions / modules corresponding to the method in the embodiments of the present disclosure. The processor 201 executes the program instructions / modules stored in the memory 202, thereby performing function applications and data processing, i.e. implementing the particle size detection method in the above embodiments.

[0088] The memory 202 can include a program storage area and a data storage area, wherein the program storage area can store an operating system and at least one application required by a function; the data storage area can store data created according to the use of the terminal device, etc. In addition, the memory 202 can include a high-speed random access memory, and can also include a non-volatile memory.

[0089] The apparatus embodiments described above are only exemplary, for example, the division of the units can be only a logical function division, and actual implementation can have another division mode, for example, multiple units or components can be combined or integrated into another system, or some features can be ignored or not executed. In addition, the coupling or direct coupling or communication connection between the units shown or discussed can be indirect coupling or communication connection through some interfaces, devices or units, and can be electrical, mechanical or other forms. The units described as separate components can or can not be physically separated, and the components shown as units can or can not be physical units, that is, they can be located in one place, or can be distributed on multiple network units. Part or all of the units can be selected to implement the embodiments according to actual needs.
