Description

Technical Field

[0001] This invention relates to the field of sample testing technology, and in particular to a sample pretreatment device for testing food and medicine homology products. Background Technology

[0002] Food and medicine homology refers to natural substances that can be used as both food and medicine. In traditional Chinese medicine theory, they are often considered to have dual effects of dietary therapy and medicinal therapy. Among the pretreatment methods for food and medicine homology products, crushing and grinding are two common processing methods, which are particularly suitable for some food or medicine materials that require the extraction of effective components. Crushing and grinding not only help to increase the contact area between the medicinal materials and water or other solvents, improve the dissolution rate of their effective components, and enhance the efficacy of medicine or dietary therapy, but also make it easier to adapt to subsequent testing work.

[0003] According to patent document CN224081277U, a pretreatment device for testing samples of food and medicine homology includes a processing device shell, a feed hopper, and a discharge port. The feed hopper is connected to the top of the processing device shell, and the discharge port is located at the bottom of one side of the processing device shell. The processing device shell contains a crushing mechanism and a grinding mechanism. The crushing mechanism includes crushing rollers, one end of which is connected to the inner wall of the processing device shell via bearings, and the other end of which extends to the front of the processing device shell. In this technical solution, adjusting the screw causes the connecting frame and sliding block to move parallel within the slot and sliding groove. The parallel movement of the connecting frame drives the servo motor on the left side to translate with the crushing rollers. This allows for adjustment of crushing parameters according to different material properties, saving time and improving overall pretreatment efficiency. While this technical solution improves pretreatment efficiency, it cannot simultaneously clean the inner wall of the grinding space and quickly discharge powdery materials, which is inconvenient during use.

[0010] Preferably, one end of the rotating column is fixedly mounted on the differential, a limit groove is opened on the side of the fixed column, a support mechanism is fixedly mounted inside the limit groove, a limit block is fixedly mounted on one end of the support mechanism, and one end of the limit block is fixedly mounted on the inner wall of the movable tube.

[0011] Preferably, a conical seat is welded to one end of the rotating column, a grinding plate is fixedly installed at the bottom of the conical seat, a rotating barrel is rotatably installed inside the barrel body, a ring seat is movably installed at the bottom of one end of the rotating barrel, the side wall of the ring seat is fixedly installed on the inner wall of the barrel body, a pushing mechanism is fixed to one end of the detection cylinder, a telescopic column is installed on the pushing mechanism, one end of the telescopic column is fixedly installed on the side of the movable plate, a wiring pipe is fixedly installed on the top of the detection cylinder, and a slot is opened on the top of the detection cylinder.

[0012] Preferably, a conical connecting barrel is fixed to the bottom of the rotating barrel, a grinding seat is fixed to the bottom of the conical connecting barrel, a fixing ring is welded to the inner wall of the rotating barrel, a limiting ring is welded to the inner wall of the conical connecting barrel, a protrusion is welded between the limiting rings, and the side of the protrusion is in movable contact with one end of the limiting post.

[0013] Preferably, a friction seat is fixed on the inner wall of the conical connecting barrel, the friction seat is in contact with the conical seat, and a movable seat is movably installed on the bottom of the grinding plate.

[0014] Preferably, the movable seat is movably installed inside the barrel body, and a filter plate is fixedly installed on the movable seat.

[0015] Preferably, a fan blade is welded to the side of the rotating barrel, and the diameter of the fan blade is larger than the diameter of the conical connecting barrel.

[0016] The technical solution provided by this invention may include the following beneficial effects: 1. This invention achieves the effect of simultaneously crushing materials and cleaning the inner wall of the barrel through the crushing component, solving the problem of powdery materials easily adhering to the inner wall of the barrel. The position of the scraper is controlled by the contact between the limiting column and the fixing ring or the limiting ring. Later, the rotating column moves up and down, so that the limiting column contacts the support points of different diameters. The position of the scraper is controlled by the horizontal movement of the limiting column. After the scraper contacts the inner wall of the rotating barrel, it achieves the scraping of the inner wall of the rotating barrel. In the state of separation between the scraper and the inner wall of the rotating barrel, the scraper, the support column and the fixing column achieve the initial crushing of the material. 2. This invention has the effect of blowing airflow to expel internal powdery materials, solving the problem that existing powdery materials are prone to clogging and are not easy to discharge quickly. By moving the rotating column downwards and the limiting column moving outwards to contact the protrusion, the limiting column and the protrusion cooperate to drive the rotating barrel to rotate. When the rotating barrel is rotating, the fan blades rotate to generate airflow. The airflow pushes the powdery materials through the filter plate and moves downwards, and the material is discharged through the airflow. The crushing component not only crushes the materials but also provides the necessary power for the rotation of the rotating barrel. 3. This invention has the effect of adjusting grinding efficiency and cleaning at the filter position, solving the problem of filter plate clogging affecting subsequent material discharge. After the material is ground by the conical seat, the material falls onto the filter plate. The conical seat drives the grinding plate to perform secondary grinding on the material on the filter plate. Later, the lifting mechanism pushes the filter plate on the movable seat to fully contact the grinding plate. Under full contact, the grinding plate forms a scraping plate to scrape and clean the surface of the filter plate, realizing the cleaning of the filter plate while grinding, and also facilitating the rapid downward fall of the material in the holes of the filter plate.

[0020] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] like Figures 1 to 8 As shown, a sample pretreatment device for detecting food and medicine homology includes: a barrel body 1; a detection component 17, which includes a detection cylinder 40, one end of which is installed inside the barrel body 1, a movable disk 45 is movably installed inside the detection cylinder 40, and a sensor 46 is fixed on one side of the movable disk 45; and a crushing component 27, which includes a rotating column 26, a fixed column 28 welded to the side of the rotating column 26, a movable tube 29 movably installed on the fixed column 28, a support column 30 and a scraper 31 welded to the movable tube 29, and a limit column 33 welded to one end of the support column 30.

[0022] Understandably, the drive motor 16 is started to drive the rotating column 26 to rotate. When the rotating column 26 rotates, it drives the fixed column 28 to rotate. When the fixed column 28 is rotating, the support column 30, scraper 31 and limit column 33 perform preliminary crushing of the falling material. After the material falls into the inside of the detection cylinder 40 through the slot 43, the movable disk 45 is located on one side inside the slot 43. The material falls on one side of the movable disk 45. The sensor 46 performs preliminary detection of heavy metals in the powder. The sensor 46 is later connected to the X-ray fluorescence spectrometer. The X-ray fluorescence spectrometer can quickly detect the powdered material. After the detection is completed, the grinding work is stopped, and the push mechanism 41 is started to push the movable disk 45 to move outward. The movable disk 45 overflows from one end of the detection cylinder 40, which facilitates the cleaning of the material inside. After the movable disk 45 returns to its position, the grinding process is carried out again.

[0023] See Figure 1 , Figure 2 , Figure 3 and Figure 4 A reinforcing base 2 is welded to the side of the barrel body 1, and a support frame 3 is welded to the bottom of the reinforcing base 2. A conical barrel 4 is fixed to the bottom of the barrel body 1, and a fixing box 5 is fixed to the bottom of the conical barrel 4. A lifting mechanism 8 is fixedly installed on the side of the conical barrel 4. A servo motor 6 is fixedly installed on the side of the fixing box 5, and a discharge pipe 7 is fixedly installed inside the fixing box 5. The top of the discharge pipe 7 is connected to the bottom of the conical barrel 4, and a conveying auger is rotatably installed inside the discharge pipe 7. One end of the conveying auger is fixedly installed on the servo motor 6. A movable cover 9 is fixedly installed on the top of the barrel 1. A sealing seat 11 and a feed pipe 10 are fixedly installed on the top of the movable cover 9. A differential 12 is movably installed on the top of the sealing seat 11. A fixing block 13 is welded to the side of the differential 12. A displacement mechanism 14 is fixedly installed on the fixing block 13. A movable column 15 is installed on the displacement mechanism 14. One end of the movable column 15 is fixedly installed on the top of the movable cover 9. A drive motor 16 is fixedly installed on the side of the differential 12.

[0024] Understandably, when the rotating drum 21 needs to rotate simultaneously to crush materials, the displacement mechanism 14 is activated to retract the movable column 15. The displacement mechanism 14 is a linear reciprocating electric push rod, which is connected to an external switch via an electric wire. The switch controls the extension and retraction of the displacement mechanism 14. After the movable column 15 retracts into the displacement mechanism 14, the rotating column 26 and the differential 12 move downwards. The rotating column 26 moves up and down inside the sealing seat 11, which ensures the seal between the rotating column 26 and the drum body 1. When the rotating column 26... 6. When moving downwards, the rotating column 26 moves from the fixed ring 37 with a large diameter to the inside of the limiting ring 38 with a small diameter. By changing the diameter between the rotating barrel 21 and the conical connecting barrel 22 from large to small, the limiting column 33 pushes the movable tube 29 and the scraper 30 to change their positions. When the rotating barrel 21 rotates, the fixed column 28, the support column 30 and the limiting column 33 inside can also complete the initial crushing of the material. At the same time, when the rotating barrel 21 rotates, the fan blade 24 generates airflow, which easily pushes the powdery material downwards through the filter plate 19 for discharge. See Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 One end of the rotating column 26 is fixedly installed on the differential 12. A limit groove 34 is opened on the side of the fixed column 28. A support mechanism 35 is fixedly installed inside the limit groove 34. A limit block 36 is fixedly installed on one end of the support mechanism 35. One end of the limit block 36 is fixedly installed on the inner wall of the movable tube 29. A conical seat 32 is welded to one end of the rotating column 26. A grinding plate 20 is fixedly installed at the bottom of the conical seat 32. A rotating barrel 21 is rotatably installed inside the barrel body 1. A ring seat 25 is movably installed at the bottom of one end of the rotating barrel 21. The side wall of the ring seat 25 is fixedly installed on the inner wall of the barrel body 1. A pushing mechanism 41 is fixed to one end of the detection cylinder 40. A telescopic column 44 is installed on the pushing mechanism 41. One end of the telescopic column 44 is fixedly installed on the side of the movable plate 45. A wiring pipe 42 is fixedly installed on the top of the detection cylinder 40. A slot 43 is opened on the top of the detection cylinder 40. A conical connecting barrel 22 is fixed to the bottom of the rotating barrel 21, and a grinding seat 23 is fixed to the bottom of the conical connecting barrel 22. A fixing ring 37 is welded to the inner wall of the rotating barrel 21, and a limiting ring 38 is welded to the inner wall of the conical connecting barrel 22. A protrusion 39 is welded between the limiting rings 38, and the side of the protrusion 39 is in contact with one end of the limiting post 33.

[0025] Understandably, when the limiting post 33 is pushed, one end of the limiting post 33 moves toward the rotating post 26. The limiting post 33 drives the movable tube 29 to move through the support post 30. As the movable tube 29 moves, it squeezes the support mechanism 35 through the limiting block 36. The support mechanism 35 is a support spring. After the support spring is compressed, it generates a rebound force. The rebound force facilitates the rapid return of the movable tube 29 to its original position later. In addition, the elasticity of the support mechanism 35 can keep one side of the scraper 31 in contact with the inner wall of the rotating barrel 21. As the rotating post 26 rotates, one end of the limiting post 33 contacts the protrusion 39. The protrusion 39 provides a fixing point. Under the support of the limiting post 33, the rotating barrel 21 is driven to rotate on the ring seat 25. The activation of the push mechanism 41 pushes the movable disc 45 outward, causing it to overflow from one end of the detection cylinder 40, facilitating the cleaning of the internal material. After the movable disc 45 returns to its original position, grinding is performed again. The conical seat 32 rotates while driving the grinding plate 20 to rotate. The grinding plate 20 rotates on the filter plate 19, achieving secondary grinding of the material. During grinding, the activation of the lifting mechanism 8 pushes the movable seat 18 up and down. Both the push mechanism 41 and the lifting mechanism 8 are linear reciprocating electric push rods. The electrical connection and working principle of the electric push rods are the same as those of the displacement mechanism 14 mentioned above. Under the push of the lifting mechanism 8, the gap between the movable seat 18 and the grinding plate 20 is adjusted, and the size of the particles after grinding is adjusted after the gap is adjusted.

[0026] See Figure 2 , Figure 3 and Figure 8 A friction seat 47 is fixed on the inner wall of the conical connecting barrel 22, and the friction seat 47 is in contact with the conical seat 32. A movable seat 18 is movably installed on the bottom of the grinding plate 20. The movable seat 18 is movably installed inside the barrel body 1, and a filter plate 19 is fixedly installed on the movable seat 18. A fan blade 24 is welded to the side of the rotating barrel 21, and the diameter of the fan blade 24 is larger than the diameter of the conical connecting barrel 22.

[0027] Understandably, the rotating barrel 21 is driven to rotate on the ring seat 25 under the support of the limiting column 33. When the rotating barrel 21 rotates, the internal fixed column 28, support column 30 and limiting column 33 can also complete the initial crushing of the material. At the same time, when the rotating barrel 21 rotates, the fan blade 24 generates airflow, which easily pushes the powdery material downward through the filter plate 19 for discharge. After the lifting mechanism 8 pushes the surface of the filter plate 19 into complete contact with the grinding plate 20, the grinding plate 20 rotates and rubs on the surface of the filter plate 19 to scrape and clean the filter plate 19. Under the drive of the airflow, the powdery material enters the discharge pipe 7 inside the fixed box 5. The servo motor 6 is started to drive the conveying auger to push the powdery material in the discharge pipe 7 outward quickly.

[0028] Working principle: During use, the required sample is fed into the interior of the barrel 1 through the feed pipe 10. One end of the feed pipe 10 extends to the top of the rotating barrel 21. Material falling from the feed pipe 10 falls directly into the interior of the rotating barrel 21. The drive motor 16 is started to drive the rotating column 26 to rotate. When the rotating column 26 rotates, it drives the fixed column 28 to rotate. In the rotating state, the fixed column 28 supports the column 30, scraper 31 and limiting column 33 to perform preliminary crushing of the falling material. During material crushing, one end of the limiting column 33 is located between the fixed rings 37. There are no protrusions 3 between the fixed rings 37. Because of the presence of 9, the limiting post 33 can rotate in the fixed ring 37. The diameter of the fixed ring 37 is smaller than the diameter of the limiting ring 38. Therefore, the diameter of the conical connecting barrel 22 gradually decreases at the position of the limiting ring 38. Under the push of the inner wall of the conical connecting barrel 22, the limiting post 33 pushes the movable tube 29 to move through the support post 30. At the same time, one end of the movable tube 29 moves inward. After the movable tube 29 moves, the scraper 31 contacts the inner wall of the rotating barrel 21. Therefore, the material is crushed and the inner wall of the rotating barrel 21 is scraped and cleaned at the same time through the fixed post 28 and the support post 30. Later, when it is necessary to rotate the rotating barrel 21 simultaneously to crush the material, the displacement mechanism 14 is activated to drive the movable column 15 to retract. The displacement mechanism 14 is a linear reciprocating electric push rod, which is connected to an external switch via an electric wire. The switch controls the extension and retraction of the displacement mechanism 14. After the movable column 15 retracts into the interior of the displacement mechanism 14, the rotating column 26 and the differential 12 move downwards. The rotating column 26 moves up and down inside the sealing seat 11, which ensures the seal between the rotating column 26 and the barrel 1. When the rotating column 26 moves downwards, the diameter between the rotating barrel 21 and the conical connecting barrel 22 changes. Under the push of the inner wall of the conical connecting barrel 22, one end of the limiting column 33 moves towards the rotating column 26. The limiting column 33 drives the movable tube 29 to move through the support column 30. As the movable tube 29 moves downwards, it squeezes the support mechanism 35 through the limiting block 36. The support mechanism 35 is a support spring, which rebounds after compression. The force and rebound force facilitate the rapid return of the movable tube 29 to its original position later. In addition, the elasticity of the support mechanism 35 ensures that one side of the scraper 31 is always in contact with the inner wall of the rotating barrel 21. Under the push of the lifting mechanism 14, the rotating column 26 moves downward. After the rotating column 26 moves downward, the limiting column 33 enters the limiting ring 38 from the inside of the fixed ring 37. As the rotating column 26 rotates, one end of the limiting column 33 contacts the protrusion 39. The protrusion 39 provides a fixing point. Under the support of the limiting column 33, the rotating barrel 21 is driven to rotate on the ring seat 25. When the rotating barrel 21 rotates, the fixed column 28, the support column 30 and the limiting column 33 inside can also complete the initial crushing of the material. The material falls directly onto the fixed column 28 and the support column 30 through the feed pipe 10. When the rotating barrel 21 rotates synchronously, the material can also be crushed. At the same time, when the rotating barrel 21 rotates, the fan blade 24 generates airflow. The airflow easily pushes the powdery material downward through the filter plate 19 for discharge. The crushed material falls between the friction seat 47 and the conical seat 32. The rotating column 26 drives the conical seat 32 to rotate, grinding and reinforcing the material. Later, as the rotating column 26 moves up and down, it controls the particle size of the ground material. After grinding, the material falls onto the filter plate 19 on the movable seat 18 and into the inside of the detection cylinder 40. After the material falls into the inside of the detection cylinder 40 through the slot 43, the movable disk 45 is located on one side inside the slot 43, and the material falls onto one side of the movable disk 45. The sensor 46 performs preliminary detection of heavy metals in the powder. The sensor 46 is later connected to an X-ray fluorescence spectrometer, and the X-ray fluorescence spectrometer... Powdered materials can be quickly tested. After testing, the grinding work is stopped, and the pushing mechanism 41 is activated to move the movable disk 45 outward. The movable disk 45 moves out from one end of the testing cylinder 40 to facilitate cleaning of the internal material. After the movable disk 45 returns to its original position, grinding is performed again. The conical seat 32 rotates while driving the grinding plate 20 to rotate. The grinding plate 20 rotates on the filter plate 19, and the rotation realizes secondary grinding of the material. During grinding, the lifting mechanism 8 is activated to move the movable seat 18 up and down. Both the pushing mechanism 41 and the lifting mechanism 8 are linear reciprocating electric push rods. The electrical connection and working principle of the electric push rods are the same as described above. Similar to displacement mechanism 14, the gap between movable seat 18 and grinding plate 20 is adjusted under the push of lifting mechanism 8. After the gap is adjusted, the size of the particles after grinding is adjusted, thereby achieving secondary grinding through grinding plate 20 and filter plate 19. The powdered material that has reached the standard will fall down through the holes on filter plate 19. Later, after lifting mechanism 8 pushes the surface of filter plate 19 into complete contact with grinding plate 20, grinding plate 20 rotates and rubs on the surface of filter plate 19, scraping and cleaning filter plate 19. Under the drive of airflow, the powdered material enters the discharge pipe 7 inside fixed box 5, and servo motor 6 is started. The conveying auger pushes the powdery material in the discharge pipe 7 outwards quickly. In addition, after the rotating column 26 moves upwards, the outer wall of the conical seat 22 approaches the inner wall of the friction seat 47, reducing the gap between the conical seat 22 and the friction seat 47. This reduction adjusts the size of the grinding particles. At the same time, the conical seat 22 moves upwards, adjusting the gap between the grinding plate 20 and the filter plate 19 when the lifting mechanism 8 is not working. After the grinding plate 20 moves upwards, it is easier to spread the material that falls on it onto the filter plate 19. Later, the airflow at the top pushes the material downwards, effectively preventing the material from accumulating in one place and affecting the subsequent discharge.
