Description

Technical Field

[0001] This utility model belongs to the field of processing equipment technology, specifically relating to a processing device for converting the tailings of traditional Chinese medicine decoction pieces into fuel. Background Technology

[0002] As an important component of the traditional Chinese medicine industry, prepared herbal pieces play an irreplaceable role in clinical treatment and health preservation. During the large-scale processing of prepared herbal pieces, to ensure their quality and efficacy, multiple processes are required, including screening, cleaning, and cutting of raw materials. This process inevitably generates a large amount of waste material, primarily in the form of ash and dregs. Although this waste material no longer meets the standards for use as prepared herbal pieces, it still retains the flammable properties of the raw materials and is essentially a biomass resource containing a certain amount of energy.

[0003] However, the current methods used by the Chinese herbal medicine processing industry to handle these waste materials are clearly limited, generally lacking a systematic mechanism for centralized collection and resource utilization. Most production enterprises simply discard or landfill the ash and residue of the herbs as waste, which not only occupies a large amount of land resources but may also have potential environmental impacts due to the characteristics of some medicinal components. More importantly, it leads to a serious waste of this valuable biomass resource, which contradicts the industrial development concepts of "resource recycling" and "green and low-carbon production."

[0004] Meanwhile, significant fuel demand remains in related industries such as the cultivation of Chinese medicinal herbs and the deep processing of other types of medicinal materials. Traditionally, these sectors have relied heavily on firewood and coal as fuel. The extensive use of firewood easily leads to ecological problems such as vegetation destruction, while coal combustion produces substantial pollutants, failing to meet environmental protection requirements. With increasingly stringent environmental policies and the continuous rise in demand for clean energy, finding a stable, environmentally friendly, and low-cost alternative fuel has become an urgent issue for the development of these industries.

[0005] Given the stark reality of severe waste in traditional Chinese medicine (TCM) processing waste and the urgent fuel needs of related industries, the resource-based treatment of waste materials such as medicinal ash and residue generated during TCM processing, converting them into usable fuel, would not only effectively solve the environmental problem of waste disposal and achieve efficient resource recycling, but also provide clean and economical fuel alternatives for related industries, reducing dependence on traditional fossil fuels and firewood resources. This approach offers significant economic and ecological benefits. Therefore, developing a processing device capable of efficiently converting TCM processing waste into fuel is a crucial direction for promoting the green upgrading of the TCM industry, possessing practical research significance and application prospects. Utility Model Content

[0006] In view of the problems mentioned above in the background art, the purpose of this utility model is to provide a processing device for converting the waste material of traditional Chinese medicine decoction pieces into fuel.

[0007] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows: A processing device for converting the waste material of traditional Chinese medicine decoction pieces into fuel includes a control cabinet and a mounting frame. A motor is installed on the top of the control cabinet, and the output end of the motor is connected to a first pulley and a second pulley. A cylinder is installed on the top of the mounting frame, and the input end of the cylinder is connected to a feed hopper. A spiral auger is rotatably installed inside the cylinder, and the power end of the spiral auger is connected to a third pulley. A first belt is connected between the third pulley and the first pulley. An extruder is connected to the output end of the cylinder, and a heating coil is wrapped around the outer wall of the extruder. A collection box is placed below the output end of the extruder. The feed hopper is fitted with an auxiliary mechanism. The feed hopper is rotatably mounted with two internal spline shafts. The two internal spline shafts pass through the feed hopper and are fixedly mounted with spherical gears. The two spherical gears mesh with each other. One of the internal spline shafts is fixedly mounted with a fourth pulley. A second belt connects the fourth pulley and the second pulley. The power input end of the auxiliary mechanism is connected to the internal spline shaft.

[0008] Further specifying, the auxiliary mechanism includes a rectangular frame inserted into the inside of the feed hopper, and two crushing rollers are rotatably installed inside the rectangular frame. The two crushing rollers cooperate with each other, and the power ends of the two crushing rollers are provided with external splines that match the internal spline shaft. When encountering clumps of Chinese herbal medicine scraps, the auxiliary mechanism can be used to achieve the purpose of crushing, ensuring the quality of subsequent fuel.

[0009] Further, the two crushing rollers are replaced with two spiral cutting rollers. The two spiral cutting rollers cooperate with each other, and the power ends of the two spiral cutting rollers are provided with external splines that match the internal spline shaft. When encountering Chinese herbal medicine tailings containing long fiber components, they can be cut off, thereby preventing processing blockage and ensuring fuel combustion efficiency.

[0010] Further, the two crushing rollers are replaced with several horizontally arranged magnetic strips, with gaps between adjacent magnetic strips. The longitudinal cross-section of the magnetic strips is triangular, and the tips of the magnetic strips face upwards. When encountering powder containing metal impurities, the magnetic properties of the magnetic strips effectively attract the metal impurities, thereby ensuring the quality of the fuel subsequently extruded and formed.

[0011] Furthermore, the feed end of the rectangular frame is provided with an inclined guide plate offset towards the center position, which serves to guide the material and ensure that the material can enter the working area of ​​the auxiliary mechanism.

[0012] The beneficial effects of using this utility model are as follows: This utility model's auxiliary mechanism, driven by the same motor, can simultaneously complete pretreatment tasks such as pulverizing clumps, cutting long fibers, or adsorbing metallic impurities. It solves the core pain points of clumping, fiber entanglement, and impurity mixing in the tailings of traditional Chinese medicine decoction pieces. Furthermore, it adopts a plug-in installation and power docking with the internal spline shaft, allowing for flexible replacement of rectangular frames with different functions according to the characteristics of the tailings without altering the main structure of the device, thus adapting to the processing needs of various traditional Chinese medicine tailings.

[0013] This invention allows for the direct feeding of leftover Chinese medicinal herbs into a hopper, enabling the efficient recycling and reuse of the leftover material by compressing it into rod-shaped fuel, thus saving energy costs. Attached Figure Description

[0015] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] Example 1: like Figures 1-6 As shown, this utility model discloses a processing device for converting the tailings of traditional Chinese medicine decoction pieces into fuel, including a control cabinet 1 and a mounting frame 2. A motor 3 is installed on the top of the control cabinet 1, and the output end of the motor 3 is connected to a first pulley 4 and a second pulley 5. A cylinder 6 is installed on the top of the mounting frame 2, and a feed hopper 7 is connected to the input end of the cylinder 6. A spiral auger 8 is rotatably matched and installed inside the cylinder 6. A third pulley 9 is connected to the power end of the spiral auger 8, and a first belt 10 is connected between the third pulley 9 and the first pulley 4. An extrusion head 11 is connected to the output end of the cylinder 6, and a heating coil 12 is wrapped around the outer wall of the extrusion head 11. A collection box 13 is placed on the lower side of the output end of the extrusion head 11. An auxiliary mechanism 14 is installed in the feed hopper 7. Two internal spline shafts 15 are rotatably installed in the feed hopper 7. After the two internal spline shafts 15 pass through the feed hopper 7, a spur gear 16 is fixedly installed. The two spur gears 16 mesh with each other. A fourth pulley 17 is fixedly installed in one of the internal spline shafts 15. A second belt 18 is connected between the fourth pulley 17 and the second pulley 5. The power input end of the auxiliary mechanism 14 is connected to the internal spline shaft 15.

[0017] In this embodiment, the output end of the motor 3 installed on the top of the control cabinet 1 is connected to the first pulley 4 and the second pulley 5. The input end of the cylinder 6 on the top of the mounting frame 2 is connected to the hopper 7, and the spiral auger 8 is rotatably installed inside. The third pulley 9 of the power end of the spiral auger 8 is linked to the first pulley 4 through the first belt 10. The output end of the cylinder 6 is connected to the extruder 11 with a heating coil 12. A receiving box 13 is provided on the lower side of the extruder 11. The hopper 7 is inserted and installed with an auxiliary mechanism 14. Two internal spline shafts 15 rotatably installed in the hopper 7 pass through and are fixedly meshed with a circular gear 16. The fourth pulley 17 of one of the internal spline shafts 15 is linked to the second pulley 5 through the second belt 18. The power input end of the auxiliary mechanism 14 is connected to the internal spline shaft 15. After the motor 3 starts, it drives the third pulley 9 to rotate the spiral auger 8 through the first pulley 4 and the first belt 10. At the same time, it drives the fourth pulley 17 through the second pulley 5 and the second belt 18 to rotate one of the internal spline shafts 15. The other internal spline shaft 15 rotates in opposite directions through the meshing of the circular gear 16, thereby providing power to the auxiliary mechanism 14. After the Chinese herbal medicine decoction pieces enter from the feed hopper 7, they are pre-treated by the auxiliary mechanism 14 and then pushed into the cylinder 6 by the spiral auger 8 for conveying and compaction. Finally, they are extruded and shaped by the extrusion head 11 heated and shaped by the heating coil 12 and fall into the collection box 13 for collection.

[0018] In summary, the device has a high degree of overall structural integration. The spiral auger 8 and auxiliary mechanism 14 are driven synchronously by the same motor 3, eliminating the need for an additional power source and simplifying the transmission system. The auxiliary mechanism 14 adopts a plug-in installation and is connected to the internal spline shaft 15 for power connection, which is convenient for disassembly and assembly. It can be flexibly adapted according to the characteristics of the tailings. Together with the shaping function of the heating coil 12, it ensures the stable quality of fuel molding and realizes the resource utilization of tailings, reducing waste.

[0019] Example 2: like Figure 4 As shown, the preferred auxiliary mechanism 14 includes a rectangular frame 141 that is inserted and installed inside the feed hopper 7. Two crushing rollers 142 are rotatably installed inside the rectangular frame 141. The two crushing rollers 142 cooperate with each other, and the power ends of the two crushing rollers 142 are provided with external splines that match the inner spline shaft 15.

[0020] In this embodiment, the auxiliary mechanism 14 includes a rectangular frame 141 inserted into the feed hopper 7. Two cooperating crushing rollers 142 are rotatably installed inside the rectangular frame 141. The power ends of the two crushing rollers 142 are provided with external splines that match the inner spline shaft 15. When there are lumps in the tail material, the crushing rollers 142 rotate relative to each other under the drive of the inner spline shaft 15 to crush the lumpy tail material. Furthermore, the roller surface of the crushing roller 142 can be provided with different specifications of protrusions or toothed structures, and the plug-in structure between the rectangular frame 141 and the feed hopper 7 supports quick replacement of crushing rollers 142 with different toothed shapes, which can be adapted to various tail materials from loose to hard lumps with a diameter of 50mm. At the same time, the speed difference between the two crushing rollers 142 can be changed by adjusting the tooth ratio of the circular gear 16, thereby improving the crushing effect. It specifically addresses the problems of poor feeding and uneven filling of the spiral auger 8 caused by the clumping of Chinese herbal medicine scraps. The uniform looseness of the crushed scrap lays the foundation for subsequent extrusion molding. Furthermore, the assembly and disassembly of the external spline and internal spline shaft 15 are convenient, facilitating maintenance and cleaning. It can adapt to scraps with different degrees of clumping without modifying the main structure of the device.

[0021] Example 3: like Figure 5 As shown, it is preferable to replace the two crushing rollers 142 with two spiral cutting rollers 143. The two spiral cutting rollers 143 cooperate with each other, and the power end of the two spiral cutting rollers 143 is provided with an external spline that matches the internal spline shaft 15.

[0022] In this embodiment, based on embodiment two, the two crushing rollers 142 are replaced with two cooperating spiral cutting rollers 143. The power ends of the two spiral cutting rollers 143 are provided with external splines that match the inner spline shaft 15. When the tailing material contains long fiber components, the spiral cutting rollers 143 rotate in the opposite direction under the drive of the inner spline shaft 15, and cut the long fibers through the shearing action of the spiral blades. Furthermore, the blade spacing of the spiral cutting roller 143 can be designed as an adjustable structure, or a replacement spiral cutting roller 143 with different blade spacing can be provided to support the control of fiber cutting length within the range of 3-8mm. At the same time, the internal structure of the rectangular frame 141 can be compatible with the mounting position of the crushing roller 142, realizing flexible switching between integrated "crushing + cutting" or separate cutting functions. It can effectively prevent long fiber tail material from getting tangled in the auger 8 or clogging the extruder 11, improve processing continuity, and make the short fibers after cutting more uniformly mixed with other tail material. This ensures the compaction density and strength of the fuel rods, improves the air permeability during combustion, reduces black smoke and unburned residue, and balances processing stability and fuel combustion efficiency.

[0023] Example 4: like Figure 6 As shown, a number of magnetic strips 144 are evenly installed inside the preferred rectangular frame 141, with gaps between adjacent magnetic strips 144. The longitudinal cross-section of the magnetic strips 144 is triangular, with the pointed ends of the magnetic strips 144 pointing upwards.

[0024] In this embodiment, based on Example 2, the two crushing rollers 142 are replaced with several horizontally installed magnetic strips 144. A gap is left between adjacent magnetic strips 144 for the tail material to pass through. The longitudinal cross section of the magnetic strips 144 is triangular with the pointed end facing upward. When the tail material contains metal impurities, the magnetic strips 144 adsorb the metal impurities through their own magnetism, preventing them from entering the subsequent processing stage. Furthermore, the magnetic strip 144 adopts a detachable installation structure, which facilitates regular cleaning of the adsorbed metal impurities. The number and density of the magnetic strip 144 can be selected according to the content of metal impurities in the tailings. At the same time, the triangular pointed design can reduce the accumulation of tailings. Combined with the inclined installation angle of the magnetic strip 144, it ensures that the tailings pass through smoothly while increasing the adsorption area. It intercepts metal impurities in the tail material in advance, preventing them from scratching the screw blades of the spiral auger 8 and clogging the discharge hole of the extruder 11, thus extending the service life of the equipment and reducing maintenance costs. At the same time, it prevents metal impurities from mixing into the fuel, avoiding safety hazards such as sparks flying and damage to the stove during combustion, and improving the safety of fuel use.

[0025] Example 5: like Figure 4 , Figure 5 As shown, the feed end of the preferred rectangular frame 141 is provided with an inclined guide plate 145 offset towards the center position.

[0026] In this embodiment, the rectangular frame 141 of the auxiliary mechanism 14 is provided with an inclined guide plate 145 offset towards the center. After the tail material enters from the feed hopper 7, it flows precisely into the working areas of the crushing roller 142, spiral cutting roller 143, etc. of the auxiliary mechanism 14 under the guidance of the inclined guide plate 145, so as to avoid deviating from the processing position. Furthermore, the inclined guide plate 145 can adopt an angle-adjustable structure, which is connected to the rectangular frame 141 by a hinge and equipped with a locking component. The guiding angle can be adjusted according to the flowability of the tail material. At the same time, the surface of the inclined guide plate 145 can be coated with polytetrafluoroethylene to reduce the adhesion and accumulation of tail material. It solves the problem of easy accumulation and inaccurate guidance of tail material at the connection between the feed hopper 7 and the auxiliary mechanism 14, ensuring that all tail material enters the pre-treatment working area and improving the utilization rate of raw materials; the adjustable angle design is suitable for tail material with different flowability, and the anti-slip coating further reduces the risk of material blockage, ensuring the continuity and stability of the processing flow.

[0027] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
