Description

Technical Field

[0001] The present invention relates to the technical field of the recovery of traditional Chinese medicine residue, and particularly to a device for recovering traditional Chinese medicine residue. Background Art

[0002] Chinese medicinal materials are natural medicines that are unprocessed or only simply processed at the place of origin, while traditional Chinese medicine decoction pieces are obtained by subjecting Chinese medicinal materials to processes such as grinding, decocting, soaking, and drying, and then cutting and pressing them into tablets. The traditional Chinese medicine decoction pieces retain the medicinal components of the Chinese medicinal materials during the production process and enhance their stability, facilitating storage and use.

[0003] After retrieval, a Chinese patent with the publication number CN214448762U discloses a device for recovering medicinal residues in the processing of traditional Chinese medicine decoction pieces, which includes a processing box, a filtering device, a pushing device, and an extrusion device; the pushing device includes a push plate, a placement groove is formed in the inner side wall of the processing box, the push plate is placed inside the placement groove, one end of the push plate is fixedly connected to the power output end of a cylinder, and the housing of the cylinder is fixedly connected to the outer surface of the processing box through a support plate. The beneficial effects of the embodiments of the present invention are as follows: the liquid medicine in the medicinal residues of traditional Chinese medicine decoction pieces is separated from the residues through the extrusion device, and after the liquid medicine is filtered by the filtering device, the residual residues in the liquid medicine are removed to ensure the cleanliness of the recovered liquid medicine, and at the same time, the residual liquid medicine in the residues is further reduced. Then, the extruded residues are pushed out through the pushing device, which improves the speed of extruding the residues and facilitates the secondary recycling of the liquid medicine and the residues. However, when this solution is actually used, there are still the following deficiencies:

[0004] When using a recovery device to extrude the residues generated during the production or processing of traditional Chinese medicine decoction pieces to achieve solid-liquid separation, generally, in order to achieve a better solid-liquid separation purpose, a relatively large extrusion force needs to be applied during the extrusion process to effectively extrude the residual water or other liquid components in the residues. However, the residues may be forcibly squeezed into the filter holes on the filter plate under the strong pressure. This situation not only seriously hinders the smooth progress of the solid-liquid separation process, reduces the separation efficiency, but also brings great inconvenience to the subsequent cleaning work.

[0005] Therefore, the present application provides a device for recovering traditional Chinese medicine residue. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to propose a device for recovering traditional Chinese medicine residue to solve the problem that it is difficult to clean the residues entering the filter holes during the extrusion process.

[0007] For the above purposes, the present invention provides a device for recycling residues of traditional Chinese medicine decoction pieces, including a recycling barrel and a barrel cover hinged to the top surface of the recycling barrel. An extrusion assembly is arranged inside the recycling barrel, and a cleaning assembly adapted to the extrusion assembly is arranged on the inner wall of the recycling barrel.

[0008] The extrusion assembly includes a spring support rod fixedly installed on the inner bottom surface of the recycling barrel.

A guide rod is fixedly installed on the outer wall of the rotating ring. A torsion spring is arranged at the telescopic end of the spring support rod.

[0009] Preferably, the outer wall of the guide rod fits with the inner walls of the annular groove and the threaded groove.

[0010] Preferably, the cleaning assembly includes a connecting plate fixedly installed on the bottom surface of the medicine placement tray.

A sliding plate is slidably installed on the inner wall of the connecting frame, and one end of the sliding plate far from the connecting plate passes through the side surface of the connecting frame. A spring is arranged between the end of the sliding plate and the inner wall of the connecting frame, and both ends of the spring are fixedly connected with the connecting frame and the sliding plate respectively. A plurality of driving rods adapted to the top rod and distributed in a linear array are fixedly installed on the top surface of the sliding plate.

[0011] Preferably, the cross-sectional shape of the outer end of the sliding plate located outside the connecting frame is an isosceles trapezoid, and the top end of the driving rod and the bottom end of the top rod are provided with corresponding inclined surfaces.

[0012] Preferably, the telescopic end of the spring support rod is rotatably connected to the bottom surface of the connecting plate, and both ends of the torsion spring are fixedly connected with the connecting plate and the spring support rod respectively. The outer diameter of the top rod is the same as the inner diameter of the through hole.

[0013] Preferably, a cylinder is arranged on the top surface of the barrel cover. The telescopic end of the cylinder passes through the top surface of the barrel cover and is fixedly installed with an extrusion disc.

[0014] Preferably, a scraping assembly corresponding to the extrusion disc is arranged on the outer wall of the barrel cover.

[0018] Advantages of the present invention:

[0019] 1. For this traditional Chinese medicine residue recovery device, by setting the recovery barrel and the extrusion assembly, the cylinder drives the extrusion plate to press-filter the residue of traditional Chinese medicine in the medicine placing tray, effectively squeezing out the water in the residue, improving the dehydration efficiency of the residue. At the same time, after the press-filtration is completed, the medicine placing tray can automatically rotate under the action of the spring support rod and the one-way bearing, and the liquid attached to the medicine placing tray is thrown off by centrifugal force, which is convenient for re-filtering and using. This design not only improves the working efficiency but also reduces the adhesion of the residue and keeps the equipment clean.

[0020] 2. For this traditional Chinese medicine residue recovery device, by setting the cleaning assembly, during the up-and-down movement of the medicine placing tray, components such as the sliding plate and the transmission rod can automatically clean the through holes, avoiding the blockage and adhesion of the residue. This automatic cleaning function not only reduces manual intervention but also improves the stability and reliability of the equipment. At the same time, through the design of the inclined surface and the isosceles trapezoidal cross-section, the sliding plate can flexibly enter and exit the threaded groove to drive the transmission rod, further improving the cleaning effect.

[0021] 3. For this traditional Chinese medicine residue recovery device, by setting the bucket cover and the scraping assembly, after the extrusion is completed, when the cylinder resets to a state flush with the bottom surface of the bucket cover, the bucket cover can be conveniently opened and fixed through the cooperation of the clamping rod and the clamping sleeve, which is convenient for the staff to handle the residue. In addition, through the cooperation of the scraping plate and the guiding plate, the residue on the bottom surface of the extrusion plate can be cleaned, and the cleaned residue can fall into the recovery barrel. This design not only simplifies the operation process but also improves the practicability and convenience of the equipment. Description of the Drawings

[0033] As Figures 1 to 6 shown, a residue recycling device for traditional Chinese medicine decoction pieces includes a recycling barrel 1 and a barrel cover 2 hinged to the top surface of the recycling barrel 1. An extrusion assembly is arranged inside the recycling barrel 1, a cleaning assembly adapted to the extrusion assembly is arranged on the inner wall of the recycling barrel 1, a cylinder 6 is arranged on the top surface of the barrel cover 2, and the telescopic end of the cylinder 6 passes through the top surface of the barrel cover 2 and is fixedly installed with an extrusion disc 7;

[0034] The extrusion assembly includes a spring support rod 31 fixedly installed on the inner bottom surface of the recycling barrel 1. A medicine placing tray 32 is arranged at the telescopic end of the spring support rod 31. A number of uniformly distributed through holes 33 are formed in the bottom surface of the medicine placing tray 32. A one-way bearing is sleeved on the outer wall of the medicine placing tray 32, and a rotating ring 34 is sleeved on the outer wall of the one-way bearing. An annular groove 35 corresponding to the rotating ring 34 is formed in the inner wall of the recycling barrel 1. A threaded groove 36 communicating with the annular groove 35 is formed in the inner wall of the recycling barrel 1 below the annular groove 35. A guide rod 37 is fixedly installed on the outer wall of the rotating ring 34, and the outer wall of the guide rod 37 is in contact with the inner walls of the annular groove 35 and the threaded groove 36. A spiral spring 38 is arranged at the telescopic end of the spring support rod 31;

[0035] During use, the staff can open the bucket cover 2, place the residues of traditional Chinese medicine decoctions in the medicine placing tray 32, then close the bucket cover 2. Subsequently, the cylinder 6 can be directly opened to extend, driving the extrusion plate 7 to move downward. During the downward movement of the extrusion plate 7, it can enter the medicine placing tray 32 to press-filter the residues inside. And as the cylinder 6 extends, the extrusion plate 7 can drive the medicine placing tray 32 to slide downward together and compress the spring support rod 31 to make it shorten. During the downward movement of the medicine placing tray 32, the guide rod 37 on the rotating ring 34 on its outer wall can enter the threaded groove 36 from the annular groove 35, and under the action of the threaded groove 36, the rotating ring 34 can be driven to rotate. However, since the one-way bearing is in a free state in this rotation direction, the rotating ring 34 cannot drive the medicine placing tray 32 to rotate. As the extrusion plate 7 extrudes the residues inside the medicine placing tray 32, the moisture in the residues can be squeezed out and discharged from the through holes 33 of the medicine placing tray 32 into the bottom of the recycling barrel 1. After the extrusion is completed, the cylinder 6 can be shortened and reset. During the reset process of the cylinder 6, the spring support rod 31 can extend to drive the medicine placing tray 32 to move upward synchronously. During the movement, the guide rod 37 can slide along the threaded groove 36 and drive the rotating ring 34 to reverse. This direction is the locking direction of the one-way bearing, so the medicine placing tray 32 can be driven to rotate, and during the rotation, the spiral spring 38 can be contracted. When the guide rod 37 enters the annular groove 35, at this time, under the action of the spiral spring 38, the medicine placing tray 32 can rotate rapidly to shake off the liquid attached to the medicine placing tray 32 for reuse of filtration.

[0036] Such as Figure 2 、 Figure 6As shown in the figure, the cleaning component includes a connecting plate 41 fixedly installed on the bottom surface of the medicine placing tray 32. The telescopic end of the spring support rod 31 is rotatably connected to the bottom surface of the connecting plate 41, and both ends of the coil spring 38 are fixedly connected to the connecting plate 41 and the spring support rod 31 respectively. A plurality of connecting frames 42 corresponding to the through holes 33 and distributed in an annular array are fixedly installed on the outer wall of the connecting plate 41. A plurality of guiding ports 43 corresponding to the through holes 33 are formed on the top surface of the connecting frame 42. A push rod 44 is slidably installed on the inner wall of the guiding port 43. The outer diameter of the push rod 44 is the same as the inner diameter of the through hole 33. A sliding plate 45 is slidably installed on the inner wall of the connecting frame 42, and one end of the sliding plate 45 far from the connecting plate 41 passes through the side surface of the connecting frame 42. The cross-sectional shape of the end of the sliding plate 45 located outside the connecting frame 42 is set as an isosceles trapezoid. A spring 46 is arranged between the end of the sliding plate 45 and the inner wall of the connecting frame 42. Both ends of the spring 46 are fixedly connected to the connecting frame 42 and the sliding plate 45 respectively. A plurality of transmission rods 47 adapted to the push rod 44 and distributed in a linear array are fixedly installed on the top surface of the sliding plate 45. The top end and the bottom end of the transmission rod 47 are provided with corresponding inclined surfaces;

[0037] During the up and down movement of the medicine placing tray 32, the end of the sliding plate 45 can be attached to the inner wall of the recycling bin 1 in the initial state. As the medicine placing tray 32 moves, the end of the sliding plate 45 can enter the thread groove 36 and slide along the thread groove 36. And as it continues to move, the sliding plate 45 can move out of the thread groove 36 under the action of the isosceles trapezoid cross-section at the end and the spring 46, realizing the driving of the sliding plate 45. During the reciprocating sliding of the sliding plate 45, the transmission rod 47 can be driven to slide, and under the action of the inclined surface, the transmission rod 47 can push the push rod 44 out of the guiding port 43 and into the through hole 33 on the bottom surface of the medicine placing tray 32, realizing the cleaning of the through hole 33 on the medicine placing tray 32 and avoiding the attachment of residues.

[0038] As Figure 4 、 Figure 5 As shown in the figure, a scraping component corresponding to the extrusion disc 7 is arranged on the outer wall of the bucket cover 2. The scraping component includes fixing plates 51 symmetrically and fixedly installed at the opening end of the bucket cover 2. A guiding groove 52 is formed on the bottom surface of the fixing plate 51. A guiding plate 53 is slidably installed on the inner wall of the guiding groove 52. A scraping plate 54 is fixedly installed at the bottom ends of the two guiding plates 53. The scraping plate 54 is made of rubber material. A clamping rod 55 is fixedly installed between the ends of the two fixing plates 51 far from the scraping plate 54. A clamping sleeve 56 adapted to the clamping rod 55 is fixedly installed on the outer wall of the recycling bin 1;

[0039] After the extrusion is completed, when the cylinder 6 resets to the state where the bottom surface of the extrusion disc 7 is flush with the bottom surface of the barrel cover 2, the barrel cover 2 can be opened at this time, and the clamping rod 55 at the end of the fixing plate 51 can be rotated into the clamping sleeve 56, so as to fix the barrel cover 2, so that the staff can handle the residue. After the barrel cover 2 is fixed, the staff can pull the scraping plate 54 so that the guide plate 53 reciprocates along the guide groove 52 on the bottom surface of the fixing plate 51, and then the residue on the bottom surface of the extrusion disc 7 can be cleaned by the scraping plate 54. The cleaned residue can fall into the recycling bucket 1 for reuse.

[0040] When the technical solution provided by the present invention is used, the staff can open the barrel cover 2, place the residue of the traditional Chinese medicine decoction pieces in the medicine placing disc 32, and then close the barrel cover 2. Subsequently, the cylinder 6 can be directly opened to extend and drive the extrusion disc 7 to move downward. During the downward movement of the extrusion disc 7, it can enter the medicine placing disc 32 to filter the residue inside. And as the cylinder 6 extends, the extrusion disc 7 can drive the medicine placing disc 32 to slide downward together and compress the spring support rod 31 to make it shorten. During the downward movement of the medicine placing disc 32, the guide rod 37 on the rotating ring 34 on its outer wall can enter the threaded groove 36 from the annular groove 35, and under the action of the threaded groove 36, it can drive the rotating ring 34 to rotate. However, since the rotation direction of this one-way bearing is in a free state, the rotating ring 34 cannot drive the medicine placing disc 32 to rotate. As the extrusion disc 7 extrudes the residue inside the medicine placing disc 32, the water in the residue can be squeezed out and discharged from the medicine placing disc 32 through the through hole 33 and enter the bottom of the recycling bucket 1. After the extrusion is completed, the cylinder 6 can be shortened and reset. During the reset process of the cylinder 6, the spring support rod 31 can extend to drive the medicine placing disc 32 to move upward synchronously. During the movement, the guide rod 37 can slide along the threaded groove 36 and drive the rotating ring 34 to reverse. This direction is the locking direction of the one-way bearing, so the medicine placing disc 32 can be driven to rotate. And during the rotation, the spiral spring 38 can be contracted. When the guide rod 37 enters the annular groove 35, at this time, under the action of the spiral spring 38, the medicine placing disc 32 can rotate quickly to throw off the liquid attached to the medicine placing disc 32 for reuse after filtration.

[0041] During the up-and-down movement of the medicine placement tray 32, the end of the slide plate 45 can be in contact with the inner wall of the recovery barrel 1 in the initial state. As the medicine placement tray 32 moves, the end of the slide plate 45 can enter the thread groove 36 and slide along the thread groove 36. With continuous movement, the slide plate 45 can move out of the thread groove 36 under the action of the isosceles trapezoid cross-section at the end and the spring 46, realizing the drive of the slide plate 45. During the reciprocating sliding of the slide plate 45, the transmission rod 47 can be driven to slide, and under the action of the inclined plane, the transmission rod 47 can push the ejector rod 44 out of the guide port 43 and into the through hole 33 at the bottom surface of the medicine placement tray 32, realizing the cleaning of the through hole 33 on the medicine placement tray 32 and avoiding the attachment of residues.

[0042] After the extrusion is completed and the cylinder 6 resets to the state where the bottom surface of the extrusion disc 7 is flush with the bottom surface of the barrel cover 2, the barrel cover 2 can be opened at this time, and the latch 55 at the end of the fixing plate 51 can be rotated into the socket 56, thereby realizing the fixation of the barrel cover 2, so as to facilitate the staff to handle the residues. After the barrel cover 2 is fixed, the staff can pull the scraper 54 to make the guide plate 53 reciprocate along the guide groove 52 at the bottom surface of the fixing plate 51, and then the residues on the bottom surface of the extrusion disc 7 can be cleaned by the scraper 54. The cleaned residues can fall into the recovery barrel 1 for reuse.
