[0001] This invention relates to the field of detection technology, specifically to a microscopic-based insoluble particle detection and filtration device and its usage method. Background Technology

[0002] In the quality control of liquid products, the content of insoluble particles is an important indicator. There are strict particle limit standards in fields such as pharmaceuticals, chemicals, new energy battery manufacturing, chip manufacturing, petroleum product quality, medical devices, and cosmetics.

[0003] Microscopy is one of the most commonly used methods for particle detection. It assesses the content of particles in liquid samples by observing and counting them under a microscope.

The pressure plate is installed on the top of the filter limiting guide slider, and the lever plate is fixed to the end of the cylindrical protrusion. The limiting engagement plate is fixed to the back of the guide plate by bolts and is used to engage and fix the cylindrical protrusion. A ring is formed at the center of the filter limiting guide slider to cooperate with the integrated disposable filter, and the ring is in contact with the outer wall surface of the integrated disposable filter.

The metal filter screen is disposed on the top of the connecting base. A filter membrane is laid on the surface of the metal filter screen. The stainless steel barrel is fitted over the outside of the connecting base.

[0015] Preferably, the drying module includes a dryer bracket, a telescopic sliding module, a dryer fixing frame, and a dryer. The dryer bracket is installed on one side of the base plate surface, the telescopic sliding module is installed on the top of the dryer bracket, the dryer fixing frame is installed at the end of the telescopic sliding module, and the dryer is installed inside the dryer fixing frame. The working area of ​​the dryer faces the filter module.

[0016] Preferably, the detection module includes a camera bracket, an image processing module, a camera module, and a microscope module. The camera bracket is mounted on the other side of the base plate surface. The image processing module is mounted on the top of the camera bracket and is used to process image information. The camera module is mounted on the bottom of the image processing module and is used to acquire image information. The image information acquired by the camera module is transmitted to the image processing module through an electrical connection. The microscope module is mounted on the bottom of the camera module and is used to magnify the image.

[0017] A method for using a microscopy-based insoluble particulate detection and filtration device includes the following steps:

[0018] Step S1: When using an integrated disposable filter, insert the integrated disposable filter into the ring at the center of the filter limiting guide slider. During the insertion process, the integrated disposable filter drives the filter limiting guide slider to move down along the guide plate. The interface at the bottom of the integrated disposable filter is inserted into the fixed male head at a vertical angle under the restriction of the filter limiting guide slider, forming a sealed connection. When the integrated disposable filter is fully inserted into the interior and fixed, the cylindrical protrusion on the back of the filter limiting guide slider engages with the interior of the limiting engagement plate. At this time, the setting position of the filter limiting guide slider remains fixed.

[0019] When selecting a stainless steel straight-mouth filter, a fastening nut is pre-installed at the end of the fixed male connector. The interface of the connecting base in the stainless steel straight-mouth filter is connected to the fixed male connector. The connecting base and the fixed male connector are fixedly connected by the fastening nut. A metal filter screen is placed on the surface of the connecting base, and a filter membrane is laid on the surface of the metal filter screen. Finally, the stainless steel bucket is placed on the outside of the connecting base.

[0020] Step S2: Start the solenoid valve and keep it in continuous operation. The solenoid valve draws air from inside the integrated disposable filter and the stainless steel straight-mouth filter through the hose and the fixed male connector, so that a stable negative pressure environment is formed inside the integrated disposable filter and the stainless steel straight-mouth filter. The liquid to be tested is injected into the integrated disposable filter and the stainless steel straight-mouth filter. Under the action of negative pressure, the liquid in the liquid to be tested passes through the filter membrane at a uniform speed. The insoluble particles in the liquid to be tested are intercepted by the filter membrane and evenly attached to the surface of the filter membrane. The filtered liquid is discharged through the hose and the solenoid valve. Continue to operate until the preset amount of liquid to be tested is completely filtered.

[0021] Step S3: Start the stepper motor of the rotating base. The stepper motor drives the turntable to rotate through the belt, which in turn drives the trigger point sensor plate and the filter fixing plate to rotate synchronously. The point sensor detects the detection point on the trigger point sensor plate in real time. After the filter module has completed the filtration operation, the stepper motor stops running, so that the filter module stops precisely below the drying module. The telescopic sliding module pushes the dryer fixing frame and the dryer to move directly above the integrated disposable filter. The dryer uses constant heating power to evenly dry the surface of the filter membrane, removes residual moisture from the filter membrane, and puts the particles in a dry, stable, and detectable state.

[0022] In step S4, the stepper motor restarts, driving the trigger point sensor plate to rotate, accurately conveying the dried material to the bottom of the detection module and stopping it. The microscope module moves down close to the filter membrane, optically magnifying the insoluble particles on the surface of the filter membrane. The camera module simultaneously captures high-definition images of the magnified particles and transmits the image data to the image processing module in real time. The image processing module analyzes, identifies, and counts the images, accurately counting the number of insoluble particles of different sizes, generating and outputting complete detection data and results.

[0023] Step S5: After the inspection is completed, for the integrated disposable filter, manually pull the lever of the insertion and removal auxiliary component upward. The lever drives the filter limiting guide slider to slide vertically upward along the vertical groove of the guide plate. The filter limiting guide slider simultaneously lifts the integrated disposable filter upward, so that the integrated disposable filter is smoothly disconnected from the fixed male head, completing the vertical disassembly of the integrated disposable filter. Repeat the installation steps of the integrated disposable filter in step S1 to complete the replenishment of the integrated disposable filter.

[0024] For stainless steel straight-mouth filters, pull the stainless steel canister upwards, remove the filter membrane from the surface of the metal filter screen, replace the new filter membrane, and then reinsert the stainless steel canister back into the connecting base.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] This invention automates the entire process from sample drying to microscopic examination result output by setting up a rotating base, a filter installation module, a filter module, a drying module, and a detection module. This avoids contamination and errors, ensures the standardization of the detection process and the accuracy of the results, and improves detection efficiency. Attached Figure Description

[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments, which illustrate the above and other technical features and advantages of the present invention. However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive.

[0037] Example:

[0038] like Figures 1-7 As shown, the present invention provides a microscopic-based insoluble particle detection and filtration device, comprising a rotating base 1, a filter mounting module 2, a filter module 3, a drying module 4, and a detection module 5;

[0039] The rotating base 1 is set on the surface of the field;

[0040] The filter mounting module 2 is mounted on the top of the rotating base 1, and the filter module 3 is mounted on the top of the filter mounting module 2. The filter mounting module 2 is used to drive the filter module 3 to rotate.

[0041] The drying module 4 and the detection module 5 are respectively located on both sides of the edge of the rotating base 1, with the working ends of the drying module 4 and the detection module 5 pointing towards the top of the filter module 3;

[0042] The rotating base 1 includes a base plate 11, a support plate 12, a synchronous drive shaft 13, a stepper motor 14, a turntable 15, and point sensors 16. The base plate 11 is placed on the surface of the site. The support plate 12 is mounted on the center of the surface of the base plate 11 via a support rod. The synchronous drive shaft 13 is mounted on the center of the support plate 12 via bearings. A set of driven wheels is mounted on the bottom end of the synchronous drive shaft 13. The stepper motor 14 is mounted on the side of the surface of the base plate 11. The output shaft of the stepper motor 14 is connected to the driven wheels at the bottom end of the synchronous drive shaft 13 via a belt. The stepper motor 14 drives the synchronous drive shaft 13 to rotate via the belt. The turntable 15 is fixed to the top of the synchronous drive shaft 13. Several sets of detection points are evenly spaced on the surface of the turntable 15. Sensor 16 is installed at the edge of support plate 12. The detection end of support plate 12 points to the detection point setting area on the surface of turntable 15. During operation, stepper motor 14 drives synchronous transmission shaft 13 to rotate via belt. Synchronous transmission shaft 13 drives turntable 15 to rotate synchronously during rotation. Point sensor 16 continuously detects detection points on the surface of turntable 15 during rotation. When point sensor 16 detects a detection point, stepper motor 14 stops working intermittently, and synchronous transmission shaft 13 stops at the current position. When stepper motor 14 starts working again, stepper motor 14 continues to drive synchronous transmission shaft 13 to rotate until the next detection point on the surface of turntable 15 reaches the position of point sensor 16.

[0043] The filter mounting module 2 includes a filter fixing plate 21 and filter fixing holes 22. The filter fixing plate 21 is mounted on the top of the turntable 15 by a support rod. Several sets of filter fixing holes 22 are equally spaced inside the turntable 15. The number of filter fixing holes 22 matches the number of detection points. During the rotation of the turntable 15, the filter fixing plate 21 mounted on the top of the turntable 15 rotates synchronously with the turntable 15. At the same time, the filter fixing holes 22 inside the filter fixing plate 21 rotate and stop synchronously with the rotation and stop of the filter fixing plate 21.

[0044] The number of filter fixing holes 22 is matched with the number of filter modules 3. Each filter fixing hole 22 contains a filter module 3. The filter module 3 includes a fixing male connector 31, a plug-in auxiliary component 32, an integrated disposable filter 33, a solenoid valve fixing plate 34, and a solenoid valve 35. The fixing male connector 31 is located inside the filter fixing hole 22. The number of plug-in auxiliary components 32 is matched with the number of fixing male connectors 31. Several sets of plug-in auxiliary components 32 are installed at equal intervals on the surface of the filter fixing plate 21, and the positions of the plug-in auxiliary components 32 correspond one-to-one with the positions of the fixing male connectors 31. The integrated disposable filter 33 is installed at the end of the fixing male connector 31 through the plug-in auxiliary component 32. The number of solenoid valve fixing plates 34 is the same as the number of fixing male connectors 31. The solenoid valve fixing plate 34 is located below the filter fixing plate 21. The solenoid valve 35 is located inside the solenoid valve fixing plate 34. The solenoid valve 35 is connected to the corresponding fixing male connector 31 through a hose.

[0045] During operation, the solenoid valve 35 draws air from the integrated disposable filter 33 through the hose, thereby creating a negative pressure inside the integrated disposable filter 33. Under the action of negative pressure, the water inside the integrated disposable filter 33 enters the solenoid valve 35 through the hose and is discharged outward through the solenoid valve 35. The particles in the water are blocked by the filter membrane and remain on the surface of the filter membrane. Throughout the entire process, the solenoid valve 35 always remains in working condition.

[0046] The insertion and removal auxiliary assembly 32 includes a guide plate 321, a filter limiting guide slider 322, a pressure plate 323, a lever plate 324, and a limiting engagement plate 325. The guide plate 321 is fixed to the surface of the filter fixing plate 21. The filter limiting guide slider 322 is disposed inside the guide plate 321. A set of vertical grooves is opened on the back of the guide plate 321. A cylindrical protrusion is formed on the back of the filter limiting guide slider 322. The cylindrical protrusion of the filter limiting guide slider 322 is engaged in the vertical groove. The pressure plate 323 is installed on the top of the filter limiting guide slider 322. The lever plate 324 is fixed to the end of the cylindrical protrusion. The limiting engagement plate 325 is fixed to the back of the guide plate 321 by bolts. The limiting engagement plate 325 is used to engage and fix the cylindrical protrusion. A ring is formed at the center of the filter limiting guide slider 322 to cooperate with the integrated disposable filter 33. The ring is in contact with the outer wall surface of the integrated disposable filter 33.

[0047] When installing the integrated disposable filter 33, insert the integrated disposable filter 33 into the annulus at the center of the filter limiting guide slider 322. During insertion, the integrated disposable filter 33 drives the filter limiting guide slider 322 to move downward along the guide plate 321. Under the constraint of the filter limiting guide slider 322, the interface at the bottom of the integrated disposable filter 33 is inserted vertically into the fixing male head 31, forming a sealed connection. When the integrated disposable filter 33 is fully inserted and fixed, the filter limiting guide slider... The cylindrical protrusion on the back of block 322 engages with the inside of the limiting engagement plate 325. At this time, the setting position of the filter limiting guide slider 322 remains fixed. When it is necessary to disconnect the integrated disposable filter 33, pull the lever 324 upward. The lever 324 simultaneously pulls the filter limiting guide slider 322 upward, causing the filter limiting guide slider 322 to move vertically upward along the guide plate 321. During the upward movement, the filter limiting guide slider 322 pulls the integrated disposable filter 33 upward, causing the integrated disposable filter 33 to move vertically out from the inside.

[0048] Filter module 3 also includes a stainless steel straight-mouth filter 36, which is installed on the top of the fixing male connector 31 by a nut. The stainless steel straight-mouth filter 36 includes a connecting base 361, a metal filter screen 362, and a stainless steel barrel 363. The connecting base 361 is fixed to the top of the fixing male connector 31 by a nut. A sealing ring is provided on the surface of the connecting base 361. The metal filter screen 362 is located on the top of the connecting base 361. A filter membrane is laid on the surface of the metal filter screen 362. The stainless steel barrel 363 is fitted over the outside of the connecting base 361.

[0049] When installing the stainless steel straight-mouth filter 36, a fastening nut is pre-installed at the end of the fixing male connector 31. The interface of the connecting base 361 in the stainless steel straight-mouth filter 36 is connected to the fixing male connector 31. The connecting base 361 and the fixing male connector 31 are fixedly connected by the fastening nut. A metal filter screen 362 is placed on the surface of the connecting base 361. A filter membrane is laid on the surface of the metal filter screen 362. Finally, the stainless steel bucket 363 is fitted over the outside of the connecting base 361.

[0050] The drying module 4 includes a dryer support 41, a telescopic sliding module 42, a dryer fixing frame 43, and a dryer 44. The dryer support 41 is installed on one side of the base plate 11, the telescopic sliding module 42 is installed on the top of the dryer support 41, the dryer fixing frame 43 is installed at the end of the telescopic sliding module 42, and the dryer 44 is installed inside the dryer fixing frame 43. When the telescopic sliding module 42 works, it pushes the dryer fixing frame 43, causing the dryer fixing frame 43 and the dryer 44 to move directly above the integrated disposable filter 33. The working area of ​​the dryer 44 faces the filter module 3.

[0051] After the integrated disposable filter 33 completes negative pressure dewatering, it rotates with the filter fixing plate 21 to the bottom of the dryer 44. The dryer 44 uses a constant heating power to dry and heat the particles on the surface of the filter membrane inside, so that the particles are dried to a detectable state.

[0052] The detection module 5 includes a camera bracket 51, an image processing module 52, a camera module 53, and a microscope module 54. The camera bracket 51 is mounted on the other side of the base plate 11. The image processing module 52 is mounted on top of the camera bracket 51 and is used to process image information. The camera module 53 is mounted on the bottom of the image processing module 52 and is used to acquire image information. The image information acquired by the camera module 53 is transmitted to the image processing module 52 through an electrical connection. The microscope module 54 is mounted on the bottom of the camera module 53 and is used to magnify the image. When the drying is complete, the microscope module 54 rotates and moves to directly below the camera module 53 along with the filter fixing plate 21. The camera module 53 then takes pictures of the particles on the filter membrane. The image processing module 52 processes the image information acquired by the camera module 53 to obtain counting information.

[0053] A method for using a microscopy-based insoluble particulate detection and filtration device includes the following steps:

[0054] Step S1: When the integrated disposable filter 33 is selected, insert the integrated disposable filter 33 into the ring at the center of the filter limiting guide slider 322. During the insertion process, the integrated disposable filter 33 drives the filter limiting guide slider 322 to move down along the guide plate 321. The interface at the bottom of the integrated disposable filter 33 is inserted into the fixing male head 31 at a vertical angle under the restriction of the filter limiting guide slider 322, forming a sealed connection. When the integrated disposable filter 33 is fully inserted into the interior and fixed, the cylindrical protrusion on the back of the filter limiting guide slider 322 engages with the interior of the limiting engagement plate 325. At this time, the setting position of the filter limiting guide slider 322 remains fixed.

[0055] When selecting the stainless steel straight-mouth filter 36, a fastening nut is pre-installed at the end of the fixing male connector 31. The interface of the connecting base 361 in the stainless steel straight-mouth filter 36 is connected to the fixing male connector 31. The connecting base 361 and the fixing male connector 31 are fixedly connected by the fastening nut. A metal filter screen 362 is placed on the surface of the connecting base 361. A filter membrane is laid on the surface of the metal filter screen 362. Finally, the stainless steel bucket 363 is fitted over the outside of the connecting base 361.

[0056] Step S2: Start the solenoid valve 35 and keep it in continuous operation. The solenoid valve 35 draws air from the integrated disposable filter 33 and the stainless steel straight-mouth filter 36 through the hose and the fixed male connector 31, so that a stable negative pressure environment is formed inside the integrated disposable filter 33 and the stainless steel straight-mouth filter 36. The liquid to be tested is injected into the integrated disposable filter 33 and the stainless steel straight-mouth filter 36. Under the action of negative pressure, the liquid in the liquid to be tested passes through the filter membrane at a uniform speed. The insoluble particles in the liquid to be tested are intercepted by the filter membrane and uniformly attached to the surface of the filter membrane. The filtered liquid is discharged through the hose and the solenoid valve 35. The operation continues until the preset amount of liquid to be tested is completely filtered.

[0057] Step S3: Start the stepper motor 14 of the rotating base 1. The stepper motor 14 drives the turntable assembly 13 to rotate via the belt, which in turn drives the trigger point sensor plate 15 and the filter fixing plate 21 to rotate synchronously. The point sensor 16 detects the detection point on the trigger point sensor plate 15 in real time. After the filter module 3 has completed the filtration operation, the stepper motor 14 stops running, so that the filter module 3 stops precisely below the drying module 4. The telescopic sliding module 42 pushes the dryer fixing frame 43 and the dryer 44 to move directly above the integrated disposable filter 33. The dryer 44 uses a constant heating power to evenly dry the surface of the filter membrane, remove the residual moisture of the filter membrane, and make the particles dry and stable in a detectable state.

[0058] In step S4, the stepper motor 14 starts again, driving the trigger point sensor plate 15 to rotate, accurately conveying the dried material to the bottom of the detection module 5 and stopping it. The microscope module 54 moves down close to the filter membrane to optically magnify the insoluble particles on the surface of the filter membrane. The camera module 53 simultaneously captures high-definition images of the magnified particles and transmits the image data to the image processing module 52 in real time. The image processing module 52 analyzes, identifies, and counts the images, accurately counts the number of insoluble particles of different sizes, and generates and outputs complete detection data and results.

[0059] Step S5: After the inspection is completed, for the integrated disposable filter 33, manually pull the lever 324 of the insertion and removal auxiliary component 32 upward. The lever 324 drives the filter limiting guide slider 322 to slide vertically upward along the vertical groove of the guide plate 321. The filter limiting guide slider 322 simultaneously lifts the integrated disposable filter 33 upward, so that the integrated disposable filter 33 is smoothly disconnected from the fixed male head 31, and the vertical disassembly of the integrated disposable filter 33 is completed. Repeat the installation steps of the integrated disposable filter 33 in step S1 to complete the replenishment of the integrated disposable filter 33.

[0060] For the stainless steel straight-mouth filter 36, pull the stainless steel barrel 363 upwards, remove the filter membrane from the surface of the metal filter screen 362, reinstall the new filter membrane, and then reinsert the stainless steel barrel 363 back into the outside of the connecting base 361.

[0061] The above are merely preferred embodiments of the present invention and are illustrative in nature, not restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, all of which will fall within the protection scope of the present invention.

10. A method of using a microscopic-based insoluble particulate detection and filtration device according to any one of claims 1-9, characterized in that, Includes the following steps: Step S1: When the integrated disposable filter (33) is selected, insert the integrated disposable filter (33) into the ring at the center of the filter limiting guide slider (322). During the insertion process, the integrated disposable filter (33) drives the filter limiting guide slider (322) to move down along the guide plate (321). The interface at the bottom of the integrated disposable filter (33) is inserted into the fixed male head (31) at a vertical angle under the restriction of the filter limiting guide slider (322), forming a sealed connection. When the integrated disposable filter (33) is fully inserted into the interior and fixed, the cylindrical protrusion on the back of the filter limiting guide slider (322) engages with the interior of the limiting engagement plate (325). At this time, the setting position of the filter limiting guide slider (322) remains fixed. When selecting a stainless steel straight-mouth filter (36), a fastening nut is pre-installed at the end of the fixed male head (31). The interface of the connecting base (361) in the stainless steel straight-mouth filter (36) is connected to the fixed male head (31). The connecting base (361) and the fixed male head (31) are fixedly connected by the fastening nut. A metal filter screen (362) is placed on the surface of the connecting base (361). A filter membrane is laid on the surface of the metal filter screen (362). Finally, a stainless steel bucket (363) is placed on the outside of the connecting base (361). Step S2: Start the solenoid valve (35) and keep it in continuous operation. The solenoid valve (35) draws air from the inside of the integrated disposable filter (33) and the stainless steel straight-mouth filter (36) through the hose and the fixed male connector (31), so that a stable negative pressure environment is formed inside the integrated disposable filter (33) and the stainless steel straight-mouth filter (36). The liquid to be tested is injected into the integrated disposable filter (33) and the stainless steel straight-mouth filter (36). Under the action of negative pressure, the liquid in the liquid to be tested passes through the filter membrane at a uniform speed. The insoluble particles in the liquid to be tested are intercepted by the filter membrane and evenly attached to the surface of the filter membrane. The filtered liquid is discharged through the hose and the solenoid valve (35). The operation continues until the preset amount of liquid to be tested is completely filtered. Step S3: Start the stepper motor (14) of the rotating base (1). The stepper motor (14) drives the turntable group (13) to rotate via the belt, thereby driving the trigger point sensor plate (15) and the filter fixing plate (21) to rotate synchronously. The point sensor (16) detects the detection point on the trigger point sensor plate (15) in real time. After the filter module (3) has completed the filtration operation, the stepper motor (14) stops running, so that the filter module (3) stops precisely below the drying module (4). The telescopic sliding module (42) pushes the dryer fixing frame (43) and the dryer (44) to move directly above the integrated disposable filter (33). The dryer (44) uses constant heating power to evenly dry the surface of the filter membrane, remove the residual moisture of the filter membrane, and make the particles dry and stable in a detectable state. In step S4, the stepper motor (14) starts again, driving the trigger point sensor plate (15) to rotate, accurately conveying the dried particles to the detection module (5) and stopping it. The microscope module (54) moves down close to the filter membrane to optically magnify the insoluble particles on the surface of the filter membrane. The camera module (53) simultaneously captures high-definition images of the magnified particles and transmits the image data to the image processing module (52) in real time. The image processing module (52) analyzes, identifies and counts the images, accurately counts the number of insoluble particles of different sizes, and generates and outputs complete detection data and results. Step S5: After the inspection is completed, for the integrated disposable filter (33), manually pull up the lever (324) of the insertion and removal auxiliary component (32). The lever (324) drives the filter limiting guide slider (322) to slide vertically upward along the vertical groove of the guide plate (321). The filter limiting guide slider (322) simultaneously lifts the integrated disposable filter (33) upward, so that the integrated disposable filter (33) is smoothly disconnected from the fixed male head (31), and the vertical disassembly of the integrated disposable filter (33) is completed. Repeat the installation steps of the integrated disposable filter (33) in step S1 to complete the replenishment of the integrated disposable filter (33). For the stainless steel straight filter (36), pull out the stainless steel barrel (363) upwards, remove the filter membrane from the surface of the metal filter screen (362), reinstall the new filter membrane, and then reinstall the stainless steel barrel (363) back into the outside of the connecting base (361).
