Description

Technical Field

[0001] The invention relates to the technical field of particle size testing, and in particular to a real-time particle size monitoring device. Background Art

[0002] The particle size distribution of particulate matter is a crucial physical property in many fields such as materials science, chemical industry, pharmaceuticals, and food processing. It directly affects the performance, quality, and optimization of production processes of products. Therefore, accurate and rapid monitoring of the particle size distribution of particulate matter is of great significance for quality control, product development, and production process monitoring. For example, a particle size detection device disclosed in application number CN202310510971.X provides a device for dispersing sample particles by generating airflow through a first suction component, a second suction component, and a flow-averaging hole. At present, particle size analysis techniques mainly include screening method, sedimentation method, microscopy method, and laser diffraction method. Among them, laser diffraction method has become one of the mainstream technologies for particle size analysis due to its wide measurement range, high precision, and fast speed.

[0003] Although laser diffraction has significant advantages in particle size analysis, there are still some technical bottlenecks in practical applications, especially for samples containing moisture. In order to obtain accurate particle size data, existing particle size monitoring devices usually need to pre-treat sample particles, including two key steps: drying and dispersion. The drying process is to remove moisture from the sample to prevent moisture from affecting the laser scattering characteristics; while the dispersion process is to disperse and separate the particles from each other to avoid measurement errors caused by adhesion between particles.

[0004] The existing technology uses mechanical stirring combined with hot air flow to remove a certain amount of moisture from the sample. This method may cause agglomeration or surface hardening between sample particles, thereby increasing the difficulty in the subsequent dispersion process. The stirring force that is difficult to accurately control is easy to cause physical damage to fragile particles, such as cracking, deformation or surface wear, which will be directly reflected in the abnormal particle size data, misleading subsequent analysis and judgment, and seriously affecting the accuracy of particle size distribution.

[0016] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0017] 1. In the process of drying the sample particles in the drying box through the air inlet pipe, as the top plate moves upward, the air flow in the connecting pipe adjusts the sliding plate through the impeller, the connecting rod and the piston to increase or decrease the telescopic length of the electromagnetic telescopic rod, so that as the number of sample particles in the sample box increases, the telescopic length of the electromagnetic telescopic rod gradually increases, and the knocking point of the eccentric wheel on the sample box gradually moves from the edge of the sample box to the center, so that the particles on the outer circle of the sample box are gradually dispersed. When the air outlet of the connecting pipe is re-closed by the adjustment plate, the connecting shaft and the impeller no longer rotate, and the solenoid valve automatically opens. As the gas in the piston cylinder gradually leaks out, the sliding plate gradually moves toward the direction of the fixed ring under the action of the elastic force of the limit spring, so that the effective resistance of the sliding rheostat increases and the current decreases, so that the magnetic field strength to which the electromagnetic telescopic rod is subjected decreases, and the telescopic end of the electromagnetic telescopic rod gradually drives the eccentric wheel to move toward the direction of the motor until the eccentric wheel no longer knocks on the support plate;

[0018] 2. After the adsorption plate has been used for a period of time, the magnetic field strength of the magnetorheological fluid coupling is increased by applying an external magnetic field, further enhancing the viscosity of the magnetorheological fluid. As the viscosity of the magnetorheological fluid in the magnetorheological fluid coupling increases, the reel that rotates with the shaft through the main bevel gear and the slave bevel gear can drive the reel to rotate through the magnetorheological fluid coupling, thereby reeling in the reel rope. When the reel rope is reeled in, the adsorption plate is driven to move toward the reel, so that the part of the adsorption plate that has not absorbed water vapor moves to the drying box to continue to absorb water vapor, while the part of the adsorption plate that has already absorbed water vapor is exposed to the air and slowly dried for subsequent recycling;

[0019] In the present invention, while the airflow dries the sample particles placed in the drying box through the air inlet pipe and the connecting pipe, under the regulating action of the impeller, the connecting rod and the piston on the sliding plate, the telescopic length of the electromagnetic telescopic rod can be increased or decreased as the particles enter the sample box through the feed pipe, so that the knocking point of the eccentric wheel on the support plate gradually moves from the edge to the center of the sample box, and then from the center to the edge of the sample box, and finally completes the dispersion of the particles in the sample box. At the same time, the two processes of drying and dispersion are completed under the action of the airflow, which not only reduces the damage to the sample caused by the drying and dispersion process, but also changes the vibration intensity according to the number of samples in the sample box, and also improves the detection efficiency of the sample.

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution 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 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 are within the scope of protection of the present invention.

[0031] The present invention will be further described below in conjunction with the embodiments.

[0032] Example: Refer to Figures 1 to 8A real-time particle size monitoring device includes a laser detector and a fixed base 1 arranged below the laser detector. A drying box 2 is fixedly installed on the top of the fixed base 1. A drying chamber 3 is arranged inside the drying box 2. A fixed plate 4 is fixedly installed on the top wall of the fixed base 1. A drying component 5 for drying samples is commonly arranged between the fixed base 1 and the drying box 2. The drying component 5 includes an air inlet pipe 51 fixedly installed at the bottom of the drying box 2. A connecting pipe 52 is fixedly connected to the air inlet pipe 51. The ends of the air inlet pipe 51 and the connecting pipe 52 close to the drying box 2 are both connected to the drying chamber 3. A sieve plate 53 is fixedly installed on the inner wall of the drying chamber 3. A top plate 54 is slidably installed on the inner wall of the drying chamber 3 and above the sieve plate 53. The four top corners of the top plate 54 are fixedly installed with main magnetic blocks. There are slave magnetic blocks magnetically attracted to each main magnetic block, the sieve plate 53 and the top plate 54 are both made of polyethylene, a plurality of air holes are provided on the top plate 54, a connecting frame 55 is fixedly installed on the side of the top plate 54 close to the connecting pipe 52, an adjusting plate 56 is fixedly connected to the connecting frame 55, an adjusting groove 561 adapted to the adjusting plate 56 is provided in the side wall of the drying box 2, both ends of the adjusting plate 56 are fixedly connected to the inner wall of the adjusting groove 561 through a return spring, a blowing hole 57 adapted to the connecting pipe 52 is provided on one end of the adjusting plate 56 close to the connecting pipe 52, a drying hole 58 adapted to the air inlet pipe 51 is provided on one end of the adjusting plate 56 close to the air inlet pipe 51, a connecting box 59 is fixedly installed on the side of the drying box 2 away from the connecting pipe 52, an exhaust hole for exhaust is provided on the top wall of the drying box 2, and a filter is fixedly installed on the exhaust hole;Under the action of the reset spring, the adjustment plate 56 placed in the adjustment slot 561 is always in a taut state. After the sample to be tested is placed in the drying box 2 through mechanical loading, a hot air blower is externally connected to the end of the air inlet pipe 51 away from the drying box 2. The airflow generated by the hot air blower blows the sample particles in the drying chamber 3 upward. At this time, the air outlet of the air inlet pipe 51 corresponds to the drying hole 58, and the air outlet of the connecting pipe 52 is closed by the adjustment plate 56. The sample particles move irregularly in the drying chamber 3. With the blowing of the airflow, the sample particles are initially dried, and some particles that are stuck together due to moisture will also be separated from each other. The sample particles pass through the through holes on the sieve plate 53 and are placed between the sieve plate 53 and the top plate 54. The water vapor generated when the airflow dries the sample will be absorbed by the dehumidification component 8. After the sample particles are dried for a period of time, as the airflow increases, some sample particles As the top plate 54 gradually moves upward, the top plate 54 will drive the adjustment plate 56 to slide upward through the connection frame 55, so that the air outlet of the connecting pipe 52 corresponds to the blowing hole 57, and the air outlet of the air inlet pipe 51 is closed by the adjustment plate 56, so that part of the sample particles placed between the sieve plate 53 and the top plate 54 can be transported to the direction of the connecting box 59, and part of the dry gas without water vapor will flow out through the air holes and the exhaust holes to prevent all the gas from being discharged through the connecting box 59 and causing the sample to scatter. When there are no sample particles between the sieve plate 53 and the top plate 54, the adjustment plate 56 moves downward under the action of the reset spring, and the air outlet of the connecting pipe 52 is re-closed by the adjustment plate 56. The top plate 54 also moves downward and resets under the magnetic force between the main magnetic block and the slave magnetic block, and continues to carry out the next round of material collection and blowing inside the drying box 2. ;

[0033] A vibration assembly 6 for dispersing the sample is commonly provided between the fixed seat 1 and the fixed plate 4. The vibration assembly 6 includes a motor 61 fixedly mounted on the outer side of the fixed plate 4. The output end of the motor 61 movably penetrates the fixed plate 4 and is fixedly connected to a rotating shaft 62. An electromagnetic telescopic rod 63 is fixedly mounted on the end of the rotating shaft 62 away from the motor 61. An eccentric wheel 64 is fixedly mounted on the telescopic end of the electromagnetic telescopic rod 63. A plurality of supporting springs 65 are fixedly mounted on the top wall of the fixed seat 1. A supporting plate 66 is commonly fixedly mounted on the top ends of the plurality of supporting springs 65. A sample box 67 is fixedly mounted on the top wall of the supporting plate 66. A feeding pipe 68 is fixedly connected to a side of the sample box 67 close to the drying box 2. The top end of the feeding pipe 68 is fixedly connected to the connecting box 59. The feeding pipe 68 has toughness. A sliding rod 69 respectively matched with each supporting spring 65 is fixedly mounted on the top of the fixed seat 1. The supporting spring 65 is sleeved on the outer side of the sliding rod 69. The top end of the sliding rod 69 movably penetrates the supporting plate 66 and is fixedly connected to a limiting ring 61. 0; When there are no sample particles in the sample box 67, the telescopic end of the electromagnetic telescopic rod 63 causes the eccentric wheel 64 to be placed on the side of the sample box 67 instead of below the sample box 67, so that the sample box 67 is in a static state. As the sample particles in the drying box 2 enter the sample box 67 through the connecting box 59 and the feeding pipe 68, under the adjustment of the adjustment component 7, the telescopic end of the electromagnetic telescopic rod 63 drives the eccentric wheel 64 to gradually move to the bottom of the sample box 67, and as the output end of the motor 61 rotates, the electromagnetic The telescopic rod 63 drives the eccentric wheel 64 to rotate together through the electromagnetic telescopic rod 63. When the eccentric wheel 64 rotates, it will knock on the bottom wall of the support plate 66. Due to the protrusion of the eccentric wheel 64, the support plate 66 can be pushed up, and the support spring 65 is stretched. As the eccentric wheel 64 rotates, the support plate 66 and the sample box 67 move downward under the action of their own gravity and the elastic force of the eccentric wheel 64, and shake to a certain extent, thereby shaking the particles in the sample box 67 to disperse them.

[0034] An adjusting assembly 7 for adjusting the vibration intensity of the vibration assembly 6 is provided in the inner wall of the drying box 2. The adjusting assembly 7 includes an adjusting tube 521 fixedly installed in the side wall of the drying box 2. A connecting shaft 71 is rotatably installed on the adjusting tube 521. An impeller 72 is fixedly installed on the end of the connecting shaft 71 close to the adjusting tube 521. A connecting ring 73 is fixedly installed on the end of the connecting shaft 71 away from the impeller 72. A connecting rod 74 is hinged at the eccentric part of the connecting ring 73. A piston cylinder 75 is fixedly installed in the inner wall of the drying box 2 close to the adjusting tube 521. A piston 76 is slidably installed on the inner wall of the piston cylinder 75. The end of the connecting rod 74 away from the connecting ring 73 is hinged to the piston 76. A fixed piston 74 is fixedly installed inside the piston cylinder 75 and above the piston 76. A slide 78 is slidably installed inside the fixed ring 77 and the piston cylinder 75 and above the fixed ring 77. A one-way valve that can only intake air in the direction of the slide 78 is provided on the fixed ring 77. A sliding rheostat is provided in the inner wall of the piston cylinder 75. The sliding rheostat includes a slide 78 slidably installed on the piston cylinder 75. The slide 78 and the electromagnetic telescopic rod 63 are electrically connected to a DC power supply and constitute a transmission ratio circuit. During the sliding process of the slide 78 toward the fixed ring 77, the resistance of the sliding rheostat in the transmission ratio circuit increases; when the air outlet of the connecting pipe 52 is no longer closed by the adjusting plate 56, the air flow blows into the drying box 2 through the connecting pipe 52 and the adjusting pipe 521, and the impeller 72 in the adjusting pipe 521 also rotates accordingly. When the impeller 72 rotates, the The connecting ring 73 is driven to rotate by the connecting shaft 71. When the connecting ring 73 rotates, the piston 76 is driven to move up and down in the piston cylinder 75 through the hinge between the connecting ring 73 and the connecting rod 74 and the hinge between the connecting rod 74 and the piston 76, so that the piston 76 presses the gas between the piston 76 and the fixed ring 77 into the space between the fixed ring 77 and the sliding plate 78 through the one-way valve on the fixed ring 77. As the sliding plate 78 slides, the effective resistance of the corresponding sliding rheostat decreases, the current increases, and the magnetic field strength received by the electromagnetic telescopic rod 63 increases, so that the telescopic length of the electromagnetic telescopic rod 63 gradually increases, and the knocking point of the eccentric wheel 64 on the sample box 67 gradually moves from the edge of the sample box 67 to the center, thereby the outer surface of the sample box 67 is moved. The particles in the circle gradually disperse, and when the air outlet of the connecting pipe 52 is re-closed by the adjusting plate 56, the connecting shaft 71 and the impeller 72 no longer rotate, and the electromagnetic valve 79 automatically opens. As the gas in the piston cylinder 75 gradually leaks out, the slide 78 gradually moves toward the direction of the fixed ring 77 under the action of the elastic force of the limit spring 710, thereby increasing the effective resistance of the sliding rheostat and reducing the current, thereby reducing the magnetic field strength of the electromagnetic telescopic rod 63, and the telescopic end of the electromagnetic telescopic rod 63 gradually drives the eccentric wheel 64 to move toward the direction of the motor 61 until the eccentric wheel 64 no longer knocks on the support plate 66, that is, the sample particles are completely dispersed. At this time, the particle size of the sample in the sample box 67 is detected by a laser detector.

[0035] The interior of the drying box 2 is provided with a dehumidification component 8 for absorbing water vapor generated when the sample is dried. The dehumidification component 8 includes a plurality of support plates 81 fixedly mounted on the fixed seat 1, on one of the support plates 81, a winding shaft 82 is rotatably mounted, a main bevel gear 83 is fixedly mounted on the outer side of the end of the rotating shaft 62 close to the motor 61, a slave bevel gear 84 is fixedly mounted on the end of the winding shaft 82 close to the motor 61, and a winding roller 86 is connected to the end of the winding shaft 82 away from the slave bevel gear 84 through a magnetorheological fluid coupling 85. The outer side of the winding roller 86 is symmetrically fixedly connected with Two winding ropes 87, one end of the two winding ropes 87 away from the winding roller 86 is fixedly connected to an adsorption plate 88, the adsorption plate 88 is filled with activated carbon particles, the adsorption plate 88 slides through the drying box 2 and the side wall of the drying box 2, a winding box 89 is fixedly installed on the outside of the drying box 2, and a reel 810 is rotatably installed inside the reel box 89, both ends of the reel 810 are fixedly installed with a spring 811, the other end of the spring 811 is fixedly connected to the inner wall of the reel box 89, and the end of the adsorption plate 88 away from the winding roller 86 is also connected to the reel through the winding rope 87. The roller 810 is fixedly connected; the magnetorheological fluid coupling 85 is a prior art, that is, the magnetorheological fluid coupling 85 uses the proportional relationship between its viscosity and the magnetic field to automatically change the transmission efficiency through the magnetic field / viscosity change. The sieve plate 53 and the top plate 54 made of polyethylene material will not adsorb water vapor and have a certain permeability to water vapor. The activated carbon particles in the adsorption plate 88 are used to adsorb water vapor. After the adsorption plate 88 has been used for a period of time, the magnetic field strength of the magnetorheological fluid coupling 85 is increased by the external magnetic field, which further enhances the viscosity of the magnetorheological fluid. As the viscosity of the magnetorheological fluid in the rheological fluid coupling 85 increases, the winding shaft 82 that rotates with the rotating shaft 62 through the main bevel gear 83 and the slave bevel gear 84 can drive the winding roller 86 to rotate through the magnetorheological fluid coupling 85, and then reel in the winding rope 87. When the winding rope 87 is reeled in, it drives the adsorption plate 88 to move toward the reel 86, so that the part of the adsorption plate 88 that has not adsorbed water vapor moves to the drying box 2 to continue to adsorb water vapor, while the part of the adsorption plate 88 that has originally adsorbed water vapor is exposed to the air and slowly dried for subsequent recycling.
