Description

Technical Field

[0001] This application relates to the field of medicinal residue recycling and grinding technology, specifically to a medicinal residue recycling device for traditional Chinese medicine processing. Background Technology

[0002] In the processing of traditional Chinese medicine (TCM), the recycling and utilization of medicinal residue is crucial. On the one hand, the residue may still contain some active ingredients; direct disposal not only wastes resources but also puts pressure on the environment. On the other hand, proper recycling and processing of the residue allows it to be applied in multiple fields, such as fertilizer production and extraction of active ingredients, maximizing resource utilization. However, existing TCM residue recycling equipment has many problems. Many traditional devices cannot finely grind the residue, resulting in inconsistent particle sizes and limiting its subsequent applications. Furthermore, these devices have low grinding efficiency, failing to meet the growing production demands of the TCM processing industry. In addition, the residue is unevenly distributed within the device, often resulting in localized accumulation and affecting the overall grinding effect. Moreover, due to unreasonable device design, residue can easily enter critical parts, affecting equipment stability and increasing maintenance costs. Additionally, the ground residue powder tends to remain within the device during output, reducing recycling efficiency. Moreover, some devices have low automation levels, relying heavily on manual operation, resulting in high labor intensity and low production efficiency.

[0003] Therefore, it is of great significance to develop a Chinese medicine processing residue recycling device that can solve the above problems, achieve fine grinding, efficient processing, stable operation, smooth output of medicinal residue, and has a flexible degree of automation. Summary of the Invention

[0004] In response to the above-mentioned technical problems, this application solves the problems of insufficient grinding of medicinal residue and low grinding efficiency in the prior art.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a dregs recycling device for traditional Chinese medicine processing, comprising a support frame, a processing bucket fixedly mounted on the support frame, a guide bucket and a support ring rotatably mounted on the processing bucket, a cover plate rotatably connected to the support ring, a main shaft rotatably mounted on the cover plate, multiple lower and upper grinding plates slidably mounted on the main shaft, filter holes provided on the lower and upper grinding plates, an inner drive plate slidably mounted on the processing bucket, two mounting plates fixedly mounted on the main shaft, a guide plate fixedly mounted on the mounting plate, a stirring rod fixedly mounted on the guide plate, the stirring rod contacting the upper grinding plate, the lower and upper grinding plates having conical cross-sections, a shim provided between the lower and upper grinding plates for adjusting the gap distance, an upper support plate fixedly mounted on the support frame, the upper support plate being fixedly connected to the cover plate, a lower connecting plate fixedly mounted on the guide bucket, and the lower connecting plate being fixedly connected to the main shaft.

[0006] Preferably, the main shaft is provided with multiple grooves, and an inner mounting ring is rotatably mounted on the grooves. Both the inner mounting ring and the main shaft are provided with sliders, and the inner mounting ring and the main shaft are connected to the upper rolling plate and the lower rolling plate respectively through the sliders.

[0007] Preferably, the inner drive plate is provided with a plurality of grooves, on which an outer mounting ring is rotatably mounted. Both the outer mounting ring and the inner drive plate are provided with sliders, and the outer mounting ring and the inner drive plate are connected to the lower rolling plate and the upper rolling plate respectively through the sliders.

[0008] Preferably, the slider of the inner drive plate is used to drive the upper rolling plate to rotate, and the slider of the main shaft is used to drive the lower rolling plate to rotate.

[0009] Preferably, the guide plate has a 0.5-turn spiral structure, and there is a gap between the end of the guide plate near the upper rolling plate and the upper rolling plate.

[0010] Preferably, a drive ring and multiple connecting plates are fixedly provided on the support ring, the drive ring extends out of the processing barrel and is rotatably connected to the processing barrel, and the connecting plates are fixedly connected to the inner drive plate.

[0011] Preferably, the cover plate is provided with multiple shafts, on which intermediate gears are fixedly installed, and an internal gear is fixedly installed on the main shaft. The internal gear meshes with multiple intermediate gears, and an external gear ring is fixedly provided on the support ring. The external gear ring meshes with multiple intermediate gears.

[0012] The technical solution provided in this application has the following advantages compared with the prior art:

[0013] 1. The lower end of the processing tank of this application is equipped with multiple sets of staggered lower and upper grinding plates, the gaps and filter hole sizes of which gradually decrease from top to bottom, so as to realize multi-level fine grinding of the medicine residue, ensure that the recycled medicine residue particles are uniform, and facilitate subsequent reuse.

[0014] 2. The inverted conical cross-section design of the lower and upper grinding plates in this application causes the dregs to gather towards the center, increasing the friction between the dregs and improving the grinding effect. At the same time, it helps dregs of the correct size to fall through the filter holes and avoids them from staying in one layer for too long.

[0015] 3. In this application, the main shaft and the inner drive plate drive the lower and upper rolling plates to rotate in opposite directions, and the guide plate also rotates in opposite directions with the upper rolling plate. This design effectively improves the rolling and grinding efficiency and shortens the processing time of the residue.

[0016] 4. The spiral structure of the guide plate in this application guides the movement of the dregs, while the stirring rod disperses the accumulated dregs, so that the dregs are evenly distributed on the upper grinding plate, further improving the grinding efficiency and effect.

[0017] This application proposes to prevent dregs from entering critical parts by rationally designing the connection method between the gasket and the lower and upper rolling plates, ensuring the smoothness of equipment rotation, improving equipment stability, reducing maintenance frequency, extending equipment service life, and improving dregs recovery efficiency.

[0018] 6. The guide bucket of this application adopts an inverted cone design, and its rotation speed is controlled by manual or electronic control system. Centrifugal force is used to smoothly detach the ground medicine residue powder from the inner wall and output it, preventing the medicine residue powder from being retained in the guide bucket and ensuring the continuity of the medicine residue recycling process.

[0019] 7. This application provides multiple driving methods, which can be operated manually, or the drive ring can be fixed and the spindle can be connected to the motor output to achieve automated grinding, or both the drive ring and the spindle can be connected to an external motor to meet the needs of different production scenarios, improve the degree of automation, reduce the intensity of manual labor, and improve production efficiency.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0031] Example 1, as Figures 1 to 8 As shown, a dregs recycling device for traditional Chinese medicine processing includes a support frame 101, a processing tank 102 fixedly mounted on the support frame 101, a guide bucket 103 and a support ring 106 rotatably mounted on the processing tank 102, a cover plate 107 rotatably connected to the support ring 106, a main shaft 108 rotatably mounted on the cover plate 107, multiple lower pressing plates 116 and upper pressing plates 117 slidably mounted on the main shaft 108, filter holes provided on the lower pressing plates 116 and upper pressing plates 117, an inner drive plate 112 slidably mounted on the processing tank 102, and two [unclear text - possibly related to a device or equipment] fixedly mounted on the main shaft 108. Mounting plate 113, a guide plate 114 is fixedly mounted on mounting plate 113, an agitator 115 is fixedly mounted on guide plate 114, the agitator 115 contacts the upper rolling plate 117, the lower rolling plate 116 and the upper rolling plate 117 have tapered cross sections, a shim is provided between the lower rolling plate 116 and the upper rolling plate 117 to adjust the gap distance, an upper support plate 121 is fixedly mounted on support frame 101, the upper support plate 121 is fixedly connected to cover plate 107, a lower connecting plate 122 is fixedly mounted on guide bucket 103, the lower connecting plate 122 is fixedly connected to main shaft 108.

[0032] Specifically, the lower end of the processing tank 102 is provided with three sets of lower grinding plates 116 and upper grinding plates 117, which are staggered. The grinding process of the medicinal residue between the lower grinding plates 116 and upper grinding plates 117 is realized by rotating the lower grinding plates 116 and upper grinding plates 117. The size of the filter holes on the lower grinding plates 116 and upper grinding plates 117 decreases from top to bottom, and the gap between the lower grinding plates 116 and upper grinding plates 117 also decreases from top to bottom. This allows the medicinal residue to fall into the lower lower grinding plates 116 and upper grinding plates 117 after being ground by the lower grinding plates 116 and upper grinding plates 117, and then fall into the lower lower grinding plates 116 and upper grinding plates 117 for more refined grinding.

[0033] The lower grinding plate 116 and the upper grinding plate 117 have an inverted conical cross-section, forming a funnel shape. After the medicinal residue falls from the top, it moves towards the main shaft 108 through the inwardly inclined surface, converging towards the center. This concentrates the residue, making the contact between them tighter and facilitating friction, thus aiding grinding. During this convergence, the residue passes through the filter holes of the lower grinding plate 116 or the upper grinding plate 117. This allows residue smaller than the filter hole size to fall through and enter the lower layer, improving the grinding effect and preventing standard-compliant residue from remaining in one layer for an extended period, thus affecting the grinding effect and efficiency of that layer.

[0034] In use, the dregs of processed Chinese medicine are put into the processing barrel 102 through the opening at the top. The dregs fall onto the uppermost grinding plate 117. The main shaft 108 drives the mounting plate 113 and the guide plate 114 to rotate. The mounting plate 113 drives the uppermost dregs to move on the upper grinding plate 117. The lower end of the guide plate 114 cooperates with the upper grinding plate 117 to crush and grind the dregs in the gap.

[0035] like Figure 3 , Figure 6 and Figure 7 As shown, the main shaft 108 is provided with multiple grooves, and an inner mounting ring 118 is rotatably mounted on the grooves. Both the inner mounting ring 118 and the main shaft 108 are provided with sliders. Through the sliders, the inner mounting ring 118 and the main shaft 108 are connected to the upper rolling plate 117 and the lower rolling plate 116, respectively.

[0036] Specifically, when installing the lower grinding plate 116 and the upper grinding plate 117, the three inner mounting rings 118 on the groove of the main shaft 108 are rotated so that the sliders on the inner mounting rings 118 are aligned with the sliders of the main shaft 108. Then, the sliding grooves of the lower grinding plate 116 and the upper grinding plate 117 are aligned with the sliders of the main shaft 108 and the inner mounting rings 118. The lower grinding plate 116 and the upper grinding plate 117 are controlled to slide on the main shaft 108 and the inner mounting rings 118. After moving to the appropriate position, the mounting shims are rotated. The distance between the lower grinding plate 116 and the upper grinding plate 117, i.e., the grinding specifications, is adjusted by the number and thickness of the shims. The gasket can rotate with the lower grinding plates 116 and 17. The lower end of the lower grinding plate 116 and the upper grinding plate 117 are provided with grooves for connecting the gasket, and the upper end is provided with protrusions. The lower end grooves make the gasket fit tightly with the lower grinding plate 116 or the upper grinding plate 117, and the upper end protrusions are located inside the gasket, that is, they are wrapped by the gasket. In this way, excessive dregs are prevented from entering between the gasket and the lower grinding plate 116, the upper grinding plate 117 and the main shaft 108, reducing the smoothness of rotation, thereby making the equipment grind stably, reducing the interval of equipment maintenance and repair, and improving the recovery efficiency of dregs.

[0037] like Figure 3 , Figure 6 and Figure 7 As shown, the inner drive plate 112 is provided with a plurality of grooves, and an outer mounting ring 119 is rotatably mounted on the grooves. Both the outer mounting ring 119 and the inner drive plate 112 are provided with sliders. Through the sliders, the outer mounting ring 119 and the inner drive plate 112 are respectively connected to the lower rolling plate 116 and the upper rolling plate 117.

[0038] like Figure 3 , Figure 6 and Figure 7 As shown, the slider of the inner drive plate 112 is used to drive the upper rolling plate 117 to rotate, and the slider of the main shaft 108 is used to drive the lower rolling plate 116 to rotate.

[0039] like Figures 3 to 6 As shown, the guide plate 114 has a spiral structure with 0.5 turns, and there is a certain gap between the end of the guide plate 114 near the upper rolling plate 117 and the upper rolling plate 117.

[0040] Specifically, when the main shaft 108 drives the mounting plate 113 and guide plate 114 to rotate, the main shaft 108 also drives the three lower rolling plates 116 to rotate via the slider, and drives the three upper rolling plates 117 to rotate via the slider on the inner drive plate 112. When the upper rolling plates 117 rotate, the end of the upper rolling plate 117 near the main shaft 108 rotates on the groove of the main shaft 108 via the inner mounting ring 118, while the end of the lower rolling plate 116 near the inner drive plate 112 rotates via the outer mounting ring 119. The inner drive plate 112 rotates on the groove, thereby driving the lower grinding plate 116 and the upper grinding plate 117 to rotate in opposite directions through the main shaft 108 and the inner drive plate 112, thereby improving the grinding and milling efficiency. The guide plate 114 and the lower grinding plate 116 rotate in the same direction, both driven by the main shaft 108. As a result, the uppermost upper grinding plate 117 and the guide plate 114 rotate in opposite directions, which in turn improves the grinding effect and efficiency of the dregs between the uppermost upper grinding plate 117 and the guide plate 114.

[0041] There are two sets of mounting plates 113, guide plates 114 and stirring rods 115, arranged symmetrically. During installation, the two mounting plates 113 are placed in the appropriate position on the main shaft 108 and fastened together, and then fixed with bolts. The protrusions on the inner wall of the mounting plates 113 cooperate with the grooves on the main shaft 108, thereby realizing the fixation of the mounting plates 113 and the ability of the main shaft 108 to transmit power to the mounting plates 113.

[0042] The spiral structure of the guide plate 114 helps the placed dregs move, guiding them between the upper grinding plate 117 and the guide plate 114 for grinding and milling. When the upper end of the guide plate 114 moves, the dregs on the upper grinding plate 117 are stirred by multiple agitators 115, thereby dispersing some of the accumulated dregs. This prevents excessive dregs in one area of ​​the upper grinding plate 117 from affecting the grinding in contact with the guide plate 114, or even causing the upper grinding plate 117 and guide plate 114 to be squeezed in the opposite direction due to excessive dregs, thus damaging their structure.

[0043] like Figure 2 and Figure 8 As shown, a drive ring 105 and a plurality of connecting plates 111 are fixedly provided on the support ring 106. The drive ring 105 extends out of the processing barrel 102 and is rotatably connected to the processing barrel 102. The connecting plates 111 are fixedly connected to the inner drive plate 112.

[0044] Specifically, the outward extension structure of the drive ring 105 allows it to be installed at the upper opening of the processing tank 102, thereby supporting components such as the support ring 106 and the cover plate 107. During use, operators can manually control the drive ring 105 to rotate, thereby driving the support ring 106 and the outer toothed ring 110 to rotate, and via multiple connecting plates 111, driving the inner drive plate 112 to rotate on the inner wall of the processing tank 102. This, in turn, drives the multiple upper crushing plates 117 to rotate via the slider of the inner drive plate 112.

[0045] like Figure 3 As shown, the cover plate 107 is provided with multiple shafts, on which intermediate gears 109 are fixedly installed. An internal gear 120 is fixedly installed on the main shaft 108. The internal gear 120 meshes with multiple intermediate gears 109. An external gear ring 110 is fixedly provided on the support ring 106. The external gear ring 110 meshes with multiple intermediate gears 109.

[0046] Specifically, the operator manually controls the guide bucket 103 to rotate, which drives the main shaft 108 to rotate on the cover plate 107 via the lower connecting plate 122 on the guide bucket 103. Consequently, the internal gear 120 on the main shaft 108 and multiple lower grinding plates 116 rotate with it. The operator controls the guide bucket 103 and the drive ring 105 to rotate in opposite directions, which makes the rotation direction of the lower grinding plates 116 and the guide plate 114 opposite to that of the upper grinding plate 117, thus aiding in grinding.

[0047] When the guide bucket 103 rotates, the dregs falling from the filter holes of the lower grinding plate 116 fall onto the inner wall of the guide bucket 103. The guide bucket 103 is an inverted cone shape, so the ground powder slides along the inclined surface. By controlling the rotation speed of the guide bucket 103, i.e., manual control, there will be speed differences due to the discontinuous power output of the operator, resulting in an unstable rotation speed of the guide bucket 103. Consequently, the inner wall of the guide bucket 103 drives the powder to rotate, applying centrifugal force to the powder, causing it to detach from the inner wall of the guide bucket 103, move downwards and be output, and not move upwards on the inner wall due to centrifugal force, thus avoiding stagnation on the inclined surface of the guide bucket 103.

[0048] In a preferred embodiment, the drive ring 105 can be fixed to the external structure, and the main shaft 108 can be connected to the output end of the motor. The motor then drives the main shaft 108, lower connecting plate 122, and guide hopper 103 to rotate, while the drive ring 105 remains stationary. This allows the main shaft 108, guide plate 114, and lower grinding plate 116 to rotate, thus achieving automated grinding. In this case, the electrical control system controls the motor on the main shaft 108 to select an appropriate rotation speed and its variation, ensuring that the powder receives sufficient centrifugal force to detach from the inner wall, without causing the powder to move upwards within the funnel due to excessive speed, which would affect the output effect.

[0049] In the preferred embodiment, both the drive ring 105 and the main shaft 108 are connected to an external motor. The main shaft 108 is connected to the output end of the motor via a shaft, while the drive ring 105 receives power from the external motor through a toothed ring, thereby driving the drive ring 105 and the main shaft 108 to rotate. This also enables automated grinding, and the rotation directions of the guide plate 114 and the lower grinding plate 116 are opposite to those of the upper grinding plate 117, improving grinding efficiency. Similarly, the motor on the main shaft 108 is controlled by an electronic control system to select an appropriate rotation speed and its variation, ensuring that the powder receives sufficient centrifugal force to detach from the inner wall, without causing the powder to move upwards within the funnel due to excessive speed, thus affecting the output effect.

[0050] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
