[0001] This utility model relates to the field of drying devices, specifically a drying device for recycling Chinese herbal medicine residue. Background Technology

[0002] Traditional Chinese medicine (TCM) residue, a byproduct of TCM production or use, contains a certain amount of active ingredients and organic matter. After processing, it can be recycled and reused as fertilizer, feed additive, or biomass energy, demonstrating significant resource reuse value. Drying is a crucial step in the recycling and processing of TCM residue, as its drying effect directly affects the storage stability, subsequent processing efficiency, and recycling quality of the residue.

[0003] Currently, the drying of Chinese herbal medicine residues mostly relies on natural air drying or traditional hot air drying equipment. Natural air drying is greatly affected by weather and environment, has a long drying cycle, low efficiency, and is easily contaminated, making it difficult to meet the needs of large-scale recycling. Although traditional hot air drying equipment can shorten the drying time, it has the following shortcomings:

[0004] 1. The dregs of medicine are prone to clumping during transportation, which prevents the hot air from fully contacting the internal materials, resulting in uneven drying and localized excessive moisture content;

[0005] 2. The lack of a pre-drying process results in high energy consumption when directly using hot air drying, and a large amount of wet residue can easily clog the conveying channel, requiring frequent manual cleaning and increasing operating costs.

[0006] 3. Insufficient dispersion of medicinal residue in some equipment affects the overall drying quality; therefore, a drying device for recycling medicinal residue of traditional Chinese medicine is proposed to address the above problems. Utility Model Content

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 scope of protection of the present utility model.

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] This application discloses a drying device for recycling traditional Chinese medicine residue. (Refer to...) Figures 1 to 4 A drying device for recycling Chinese herbal medicine residue includes a base assembly 1, a drying box assembly 3, and a conveying assembly 4.

[0032] The base assembly 1 includes a base 101, and a mounting groove 102 is provided on the top of the base 101. A belt conveyor 2 is installed in the mounting groove 102.

[0033] The drying chamber assembly 3 includes a chamber body 301, on the inner wall of which a vibrating screen 302 is installed. Multiple drying fans 303 are installed on the top of the chamber body 301. A connection port 304 is provided on the top plate of the chamber body 301. The bottom of the conveying pipe 401 is connected to the connection port 304. Multiple mounting holes are provided on the top of the chamber body 301 and are installed correspondingly to the output ends of the multiple drying fans 303. The bottom end of the chamber body 301 is fixedly connected to the top of the belt conveyor 2. The drying fans 303 are located directly above the belt conveyor 2. Three hinges 6 are fixedly connected to each of the two side plates of the chamber body 301. A single door panel 7 is hinged to the chamber body 301 through the three hinges 6. The two door panels 7 are connected by a door lock.

[0034] The vibrating screen 302 works in conjunction with the drying fan 303 to solve the problem of uneven drying caused by the clumping of medicinal residue; the connection port 304 ensures that the medicinal residue falls accurately into the box and avoids leakage; the belt conveyor 2 is fixed to the bottom of the box 301 to ensure continuous output of medicinal residue; the mounting groove 102 of the base 101 fixes the position of the conveyor and prevents displacement during operation.

[0035] The door panels 7 on both sides of the chamber 301 are hinged by hinges 6 and fixed by door locks. During normal operation, the chamber is kept closed to reduce heat loss. When maintenance or cleaning is required, the door panels 7 can be opened for easy operation. The hinges 6 and door locks work together to balance the sealing and maintainability of the chamber 301, ensuring drying efficiency while facilitating equipment maintenance.

[0036] The conveying assembly 4 includes a conveying pipe 401, a motor 402 is installed on one side of the conveying pipe 401, a spiral conveying shaft 403 is fixedly connected to the output end of the motor 402, a feed box 404 is fixedly connected to the top of the conveying pipe 401, a heating block 5 is embedded in the conveying pipe 401, a feed inlet is opened at the top of the conveying pipe 401, the bottom of the feed box 404 is fixed inside the feed inlet, a support plate 8 is fixedly connected to the bottom of the conveying pipe 401, and the bottom end of the support plate 8 is fixedly connected to the top surface of the box body 301.

[0037] The spiral conveyor shaft 403 works in conjunction with the conveying pipe 401 to achieve continuous conveying of the dregs. The heating block 5 preheats and dries the dregs simultaneously. The support plate 8 connects the conveying pipe 401 to the top of the box 301 to ensure the stability of the conveying pipe and avoid vibration from affecting the conveying accuracy.

[0038] Working principle:

[0039] Feeding and initial conveying and drying:

[0040] The dregs of Chinese medicine are fed into the feed box 404. Since the bottom of the feed box 404 is fixed in the feed inlet of the conveying pipe 401, the dregs fall directly into the conveying pipe 401.

[0041] When the motor 402 starts, its output end drives the spiral conveyor shaft 403 to rotate inside the conveying pipe 401. The spiral blades push the dregs of medicine to move downward along the conveying pipe 401. The conveying direction is determined by the direction of the motor drive.

[0042] Meanwhile, the heating block 5 embedded in the conveying pipe 401 is energized and heats up to preliminarily heat and dry the dregs inside the pipe, reducing the processing load of the subsequent drying chamber.

[0043] Entering the drying oven for dispersion drying:

[0044] The preliminarily dried medicinal residue is conveyed to the bottom of the conveying pipe 401 by the screw conveyor shaft 403, and falls into the box 301 through the connection port 304 on the top plate of the box 301.

[0045] The dregs first fall onto the vibrating screen 302 installed on the inner wall of the housing 301. When the vibrating screen 302 vibrates, it breaks up the clumps of dregs, increasing the contact area between the dregs and the hot air.

[0046] Multiple drying fans 303 on the top of the housing 301 are installed through the mounting ports. Their output ends blow hot air downwards. Because the drying fans 303 are located directly above the belt conveyor 2, the hot air directly acts on the dispersed medicinal residue on the vibrating screen 302 to achieve secondary deep drying.

[0047] Output of dried medicinal residue:

[0048] The medicinal residue that meets the particle size requirements after being screened and dried by the vibrating screen 302 falls directly into the belt conveyor 2 at the bottom of the box 301. The bottom of the box 301 is fixed to the top of the belt conveyor 2.

[0049] The belt conveyor 2 is installed in the mounting slot 102 of the base 101. The belt conveyor transports the dried dregs out of the box 301 to complete the entire drying process.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
