Detailed Implementation

[0038] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0039] See appendix Figure 1-16 This utility model discloses a traditional Chinese medicine oral liquid filtration and impurity removal device, including: a cylinder 11, a conical filter screen 2 and an inlet pipe 31;

[0040] The top of the cylinder 11 is provided with a cover plate 12, and an installation port 121 is provided on the cover plate 12. The bottom end of the cover plate 12 is connected to a drain pipe 111.

[0041] The conical filter screen 2 is arranged coaxially with the cylinder 11. The small end of the filter screen is arranged in the direction of the bottom end of the cylinder 11, and its large end is tightly connected to the inner wall of the cylinder 11. The filter pore size of the conical filter screen 2 gradually decreases from the large end to the small end.

[0042] The liquid inlet pipe 31 is slidably connected to the mounting port 121 along the axial direction of the cylinder 11, and the liquid outlet of the liquid inlet pipe 31 is arranged opposite to the mesh surface of the conical filter screen 2.

[0043] Specifically, the mesh size of the conical filter 2 gradually decreases from 3mm to 0.5mm and is uniformly reduced to perform preliminary filtration of the medicine.

[0044] More specifically, the conical filter 2 is made of 316L stainless steel plate with a thickness of 3mm.

[0045] More specifically, the top opening of the cylinder 11 and the outer side of the bottom end of the cover plate 12 are recessed to form an annular recess 122 in the direction of its center. The annular recess 122 is located inside the cylinder 11 and its wall surface is in clearance fit with the inner wall surface of the cylinder 11. Thus, the cover plate 12 and the top opening of the cylinder 11 can be limited.

[0046] In some embodiments, the cylinder 11 includes a frustoconical section 113 and a constant-diameter section 112. The larger end of the frustoconical section 113 is integrally formed with the lower end of the constant-diameter section 112. The cover plate 12 is detachably connected to the upper end of the constant-diameter section 112, and the larger end of the conical filter screen 2 is securely connected to the inner wall surface of the constant-diameter section 112. Thus, the filtered liquid medicine obtained through the conical filter screen 2 can be collected through the frustoconical section 113 for convenient subsequent discharge.

[0047] More specifically, it also includes a support frame 4, which includes a support ring 41 and a support pressure ring 42. The outer ring surface of the support ring 41 is coaxially arranged and tightly connected to the inner wall surface of the equal diameter section 112. The inner ring surface of the support ring 41 is parallel to the conical surface of the conical filter screen 2. The outer conical surface of the large end of the conical filter screen 2 contacts and abuts against the inner ring surface of the support ring 41. The support pressure ring 42 is coaxially arranged with the support ring 41. The outer ring surface of the support pressure ring 42 is tightly connected to the inner ring surface of the support ring 41. The thickness of the support pressure ring 42 along the inner ring surface perpendicular to the support ring 41 is greater than the thickness of the conical filter screen 2. The outer ring surface of the support pressure ring 42 is provided with a circumferentially arranged annular groove. The large end of the conical filter screen 2 is located in the annular groove and is in clearance fit with the annular groove to fix the large end of the conical filter screen 2.

[0048] Specifically, the outer ring surface of the support ring 42 and the inner ring surface of the support ring 41 are fastened together by bolts or sealant.

[0049] More specifically, there is an interference fit between the annular groove and the large end face of the conical filter screen 2.

[0050] In other embodiments, a connecting frame 32 and a guide plate 33 are also included. The connecting frame 32 is securely connected to the inner wall of the outlet end of the inlet pipe 31. The guide plate 33 is conical and coaxially arranged with the inlet pipe 31, with its conical surface facing the outlet end of the inlet pipe 31. The tip of the guide plate 33 is securely connected to the connecting frame 32 via a connecting post. Thus, the path of the liquid medicine entering the cylinder 11 through the outlet end of the inlet pipe 31 can be changed by the guide plate 33, allowing it to be directly sprayed onto the filter surface of the conical filter screen 2.

[0051] In one embodiment, the generatrix of the conical surface of the guide plate 33 and the generatrix of the conical surface of the conical filter 2 are perpendicular to each other in the same plane so that the liquid medicine on the guide plate 33 is sprayed onto the mesh surface of the conical filter 2 with a large impact force in a short time.

[0052] This ensures that the impact force of the liquid on the filter surface of the conical filter 2 is kept at its maximum, thereby improving filtration efficiency.

[0053] In one embodiment, a servo motor 5 is also included. The fixed end of the servo motor 5 is fastened to the upper surface of the cover plate 12. A rack 34 is fastened to the outer wall of the inlet pipe 31 along its axial direction. The power output end of the servo motor 5 is fastened to a gear that meshes with the rack 34 to adjust the lifting and lowering of the inlet pipe 31 to correspond to different heights of the conical filter screen 2. Thus, the length of the inlet pipe 31 inserted into the cylinder 11 can be controlled by the servo motor 5. By adjusting the length inserted into the cylinder 11, the outlet end of the inlet pipe 31 can cooperate with the filter surface of the conical filter screen 2, which has different pore sizes, to achieve different filtration precision.

[0054] In some embodiments, the system also includes a liquid tank 6 and a water pump 7. The liquid tank 6 contains the liquid to be filtered. The fixed end of the water pump 7 is fastened to the outer wall of the equal diameter section 112. The inlet port of the water pump 7 is located below the liquid level of the liquid to be filtered. The outlet port of the water pump 7 is connected to the inlet end of the inlet pipe 31 via a flexible hose 35.

[0055] In this embodiment, a return pipe 8 is also included. The inlet end of the return pipe 8 is connected to the small end of the conical filter screen 2 and is arranged opposite to the guide plate 33. The outlet end of the return pipe 8 passes through the side wall of the frustum section 113 and is connected to the upper end of the liquid tank 6. Thus, the residue filtered by the conical filter screen 2 can be discharged into the liquid tank 6 through the return pipe 8.

[0056] Specifically, a gauze bag is fitted at the outlet end of the return pipe 8 to collect the discharged residue.

[0057] Specifically, the inlet end of the return pipe 8 is funnel-shaped, and the conical surface of the inlet end is arranged parallel to the conical surface of the conical filter screen 2. The large end of the inlet end is provided with an annular slot 81 that is parallel to its conical surface and perpendicular to its end face. The small end of the conical filter screen 2 is fastened to the slot 81.

[0058] In some specific embodiments, the diameter of the return pipe 8 is smaller than the diameter of the inlet pipe 31.

[0059] In some other specific embodiments, it also includes support legs 9, with multiple support legs 9 arranged circumferentially along the axis of the cylinder 11, and the top ends of the multiple support legs 9 being fastened to the outer side wall of the frustum section 113.

[0060] In some other embodiments, the number of legs 9 is 3.

[0061] Specifically, it also includes a controller, which is electrically connected to the water pump 7 and the servo motor 5.

[0062] The specific principle and usage of the traditional Chinese medicine oral liquid filtration and impurity removal device provided in this embodiment are as follows:

[0063] 1. According to the filtration requirements, the length of the liquid inlet pipe 31 inserted into the cylinder 11 is adjusted by controlling the servo motor 5 through the controller;

[0064] 2. Turn on the water pump 7. The water pump 7 draws the liquid to be filtered from the liquid tank 6, enters the liquid inlet pipe 31 through the hose 35, and is sprayed onto the filter surface of the cone filter screen 2 after being guided by the guide plate 33.

[0065] 3. After the medicine is filtered through the filtration aperture of the conical filter screen 2, it is discharged through the drain pipe 111. The filtered residue is collected at the small end of the conical filter screen 2 and discharged through the return pipe 8. Finally, it is collected in the gauze bag fitted at the outlet end of the return pipe 8.

[0066] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
