[0001] This utility model belongs to the technical field of pharmaceutical experimental filtration devices, specifically a multi-stage filtration sample filtration device. Background Technology

[0002] Drugs need to be dissolved during the testing process. The components of the drug are then analyzed by extracting the solution. This process requires the use of a filtration device. Currently, most laboratories use funnels and filter paper for filtration. To improve the filtration effect and efficiency, some laboratories also use filtration equipment.

[0003] According to the testing grinding and filtering device with announcement number CN213434745U, which relates to the technical field of pharmaceutical laboratory filtration equipment, it includes a base, a motor, a pressure sensor and a display screen assembly. The bottom of the base has a reserved sliding groove, and one end of a telescopic rod is hinged to the top of the sliding sleeve. The other end of the telescopic rod is hinged to the bottom of the grinding seat. A wear-resistant disc is fixed at the top center of the grinding seat.

[0004] The aforementioned device grinds and collects drugs by grinding and filtering with a grinding disc, but its filtration method is relatively simple, and there are still many impurities in the drugs, which affects the purity of the drug samples. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-stage filtration sample filtration device to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-stage filtration sample filtration device, comprising a support frame and a refining component, wherein an mounting frame is fixedly provided at the upper end of the support frame, and a feed hopper is fixedly provided at the top end of the mounting frame; A refining component is fixedly provided on the inner side of the mounting frame. The refining component includes two sets of crushing rollers rotatably disposed on the upper end of the inner side of the mounting frame. A guide plate is fixedly provided on the lower end of the two sets of crushing rollers. Two sets of refining rollers are rotatably disposed on the lower end of the inner side of the mounting frame. A rotating disk is fixedly provided on the right end of the crushing rollers and the refining rollers. A drive component is fixedly installed at the rear end of the mounting frame, a movable component is fixedly installed on the inner side of the support frame, and a discharge component is fixedly installed at the front end of the support frame.

[0007] Preferably, the driving component includes a drive motor fixedly disposed at the rear end of the mounting frame, one end of the output shaft of the drive motor being fixedly connected to one end of the crushing roller, and a rotating belt being movably disposed on the outer side of the rotating disk.

[0008] Preferably, the movable component includes a limiting frame fixedly disposed at the bottom end of the mounting frame, a placement cylinder rotatably disposed on the inner side of the limiting frame, a movable motor fixedly disposed at the bottom end of the placement cylinder, a rotating shaft fixedly disposed at one end of the output shaft of the movable motor, and the rotating shaft passing through the inner side of the placement cylinder.

[0009] Preferably, the movable component further includes a sliding groove formed on the inner side of the upper end of the limiting frame, and a sliding wheel is fixedly provided on the outer side of the placement cylinder.

[0010] Preferably, the sliding groove matches the sliding wheel.

[0011] Preferably, a filter component is fixedly provided inside the placement cylinder. The filter component includes a filter cylinder fixedly provided inside the placement cylinder, a filter disc fixedly provided inside the upper end of the filter cylinder, and a storage tank fixedly provided at the bottom end of the filter cylinder.

[0012] Preferably, the discharge component includes a guide pipe fixedly disposed at one end of the storage tank, and one end of the guide pipe is connected to a medicine storage tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention uses a drive motor to rotate a rotating belt and multiple rotating discs, enabling multiple pulverizing rollers and multiple refining rollers to rotate synchronously. This process pulverizes and refines the drug sample fed into the upper part, making it easier for the active ingredients and impurities to disperse in the solvent, ensuring thorough separation of impurities from the filtrate and improving the filtration effect. When the pulverized and refined drug sample enters the placement cylinder at the lower end, a drive motor rotates the placement cylinder, using high-speed centrifugation to separate impurities from the filtrate. The pulverized sample at the upper end can be filtered through the filter discs to remove larger impurity particles. The filtrate after filtration is further separated by the centrifugal force generated by the filter cylinder at the lower end, resulting in more thorough separation and effectively reducing impurity residue. This ensures that the solid impurity content in the filtrate is extremely low, preventing impurities from interfering with subsequent testing. The separated filtrate can enter the storage tank at the lower end and be fed into the drug storage tank through a guide pipe for convenient and unified collection. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 , Figure 2 and Figure 4 In this invention, a technical solution is provided: a multi-stage filtration sample filtration device, including a support frame 1 and a refining component 2. An installation frame 11 is fixedly installed at the upper end of the support frame 1, and a feed hopper 12 is fixedly installed at the top of the installation frame 11. A refining component 2 is fixedly installed on the inner side of the mounting frame 11. The refining component 2 includes two sets of crushing rollers 21 rotatably installed on the upper inner side of the mounting frame 11. A guide plate 22 is fixedly installed on the lower end of the two sets of crushing rollers 21. Two sets of refining rollers 23 are rotatably installed on the lower inner side of the mounting frame 11. A rotating disk 24 is fixedly installed on the right end of the crushing rollers 21 and the refining rollers 23.

[0018] Specifically, the support frame 1 provides space for fixing and installing the upper mounting frame 11 and the feed hopper 12. The feed hopper 12 is used to add the sample to be filtered and refined. The sample is crushed and refined by multiple sets of crushing rollers 21 and multiple sets of refining rollers 23 at the lower end, so that the effective components and impurities are more easily dispersed in the solvent, ensuring that the impurities are fully separated from the filtrate and improving the reliability of filtration.

[0019] exist Figure 2 and Figure 4 In the middle: A drive component 3 is fixedly installed at the rear end of the mounting frame 11. The drive component 3 includes a drive motor 31 fixedly installed at the rear end of the mounting frame 11. One end of the output shaft of the drive motor 31 is fixedly connected to one end of the crushing roller 21. A rotating belt 32 is movably installed on the outer side of the rotating disk 24.

[0020] Specifically, when it is necessary to pulverize and refine the drug sample, the drive motor 31 can be driven to rotate multiple sets of rotating disks 24 through the rotating belt 32, so that multiple sets of pulverizing rollers 21 and multiple sets of refining rollers 23 can rotate synchronously to pulverize and refine the drug sample fed in from the top.

[0021] exist Figures 1-4 In the middle: A movable part 4 is fixedly installed on the inner side of the support frame 1. The movable part 4 includes a limiting frame 41 fixedly installed at the bottom end of the mounting frame 11. A placement cylinder 42 is rotatably installed on the inner side of the limiting frame 41. A movable motor 43 is fixedly installed at the bottom end of the placement cylinder 42. A rotating shaft 44 is fixedly installed at one end of the output shaft of the movable motor 43, and the rotating shaft 44 passes through the placement cylinder 42.

[0022] Specifically, when the pulverized drug sample enters the lower placement cylinder 42, the movable motor 43 can be driven to rotate the placement cylinder 42, and the impurities in the sample are separated from the filtrate by high-speed centrifugation.

[0023] exist Figures 1-4 In the middle: the movable part 4 also includes a sliding groove 45 opened on the inner side of the upper end of the limit frame 41, and a sliding wheel 46 is fixedly provided on the outer side of the placement cylinder 42, and the sliding groove 45 matches the sliding wheel 46.

[0024] Specifically, when the motor 43 drives the placement cylinder 42 to rotate, the movement range of the placement cylinder 42 is limited by the mutual sliding between the sliding wheel 46 and the sliding groove 45, preventing it from shaking too much. This effectively ensures the stability of the centrifugation effect and avoids sample contamination and equipment damage.

[0025] exist Figure 3 and Figure 4 In the middle: A filter component 5 is fixedly installed inside the placement cylinder 42. The filter component 5 includes a filter cylinder 51 fixedly installed inside the placement cylinder 42. A filter plate 52 is fixedly installed inside the upper end of the filter cylinder 51, and a storage tank 53 is fixedly installed at the bottom end of the filter cylinder 51.

[0026] Specifically, the sample after being finely pulverized at the top can be filtered through the filter plate 52 to filter out larger impurity particles. The filtrate after filtration can be separated by the centrifugal force generated by the filter cylinder 51 at the bottom. The separated filtrate can enter the storage tank 53 at the bottom, making the separation more thorough, effectively reducing the residue of impurities, and making the solid impurity parameters in the filtrate extremely low, avoiding impurities interfering with subsequent testing.

[0027] exist Figures 1-3In the middle: a discharge component 6 is fixedly installed at the front end of the support frame 1. The discharge component 6 includes a guide pipe 61 fixedly installed at one end of the storage tank 53. A medicine storage tank 62 is connected to one end of the guide pipe 61.

[0028] Specifically, the filtrate after refining and filtration can be fed into the storage tank 62 through the guide pipe 61 for convenient and unified collection.

[0029] When it is necessary to pulverize and refine the drug sample, the sample to be filtered and refined is fed into the feed hopper 12, and the drive motor 31 is driven to rotate multiple sets of rotating disks 24 through the rotating belt 32, so that multiple sets of pulverizing rollers 21 and multiple sets of refining rollers 23 can rotate synchronously to pulverize and refine the drug sample fed into the upper end. When the pulverized drug sample enters the lower placement cylinder 42, the movable motor 43 can drive the placement cylinder 42 to rotate. High-speed centrifugation separates the impurities and filtrate in the sample. The pulverized sample at the upper end can be filtered through the filter plate 52 to filter out larger impurity particles. The filtered filtrate can be separated by the centrifugal force generated by the lower filter cylinder 51. The separated filtrate can enter the lower storage tank 53 and be fed into the drug storage tank 62 through the guide pipe 61 for convenient and unified collection.

[0030] Electrical equipment (including but not limited to drive motor 31, movable motor 43, etc.) is safely powered by an external power source and controlled by a control box. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
