Description

Technical Field

[0001] This utility model relates to the technical field of belt dryers, and specifically discloses a belt dryer for traditional Chinese medicine that is easy to clean. Background Technology

[0002] Traditional Chinese medicine (TCM) is mainly composed of plant-based, animal-based, and mineral-based medicines. To ensure the efficacy of TCM and facilitate its storage and transportation, it is essential to effectively remove internal moisture through a drying process after harvesting or processing. This prevents mold and insect infestation and preserves its active ingredients to the maximum extent possible.

[0003] In existing technologies, belt dryers are widely used as efficient continuous drying equipment in this field. They use a stainless steel mesh belt to carry materials and move them within the chamber to dry them, offering the advantage of continuous operation. However, in practical applications, after drying medicinal materials, residual dregs, dust, and other impurities easily adhere to the surface of the mesh belt and may even become embedded in its pores. Because there is no cleaning mechanism, this not only leads to cross-contamination between different medicinal materials, affecting drug quality, but also, over time, can clog the mesh and even breed microorganisms.

[0004] Therefore, a belt dryer for traditional Chinese medicine that is easy to clean is needed to solve the above problems. Utility Model Content

[0005] This invention proposes a belt dryer for Chinese medicine that is easy to clean. After the drying process, the stainless steel mesh belt can be easily cleaned, thereby avoiding mesh blockage, microbial growth, and cross-contamination between different batches of medicinal materials.

[0006] This utility model is implemented as follows: a Chinese herbal medicine belt dryer that is easy to clean includes two connecting plates, two drive rollers are rotatably connected between the two connecting plates, and a stainless steel mesh belt is driven between the two drive rollers. A drive motor with its output end fixedly connected to one of the drive rollers is installed on the outer wall of the front connecting plate. A rinsing mechanism and a filtering mechanism are provided on the lower side of the two connecting plates. The rinsing mechanism includes a housing fixedly connected to the lower ends of two connecting plates. Two support rollers are rotatably connected inside the housing. The stainless steel mesh belt extends into the housing and abuts against the outer walls of the two support rollers. A water pipe is fixedly connected inside the housing. A diversion shell is connected to the left and lower sides of the outer wall of the water pipe. Multiple first high-pressure nozzles are connected to the left end of the left diversion shell, and multiple second high-pressure nozzles are connected to the lower end of the lower diversion shell. A booster pump with its outlet end connected to the inside of the water pipe is installed on the outer wall of the housing. The filtration mechanism passes through a passage slot at the rear end of the housing. A collection frame extending into the housing is inserted into the passage slot. A filter screen is fixedly connected inside the collection frame. A sealing plate is fixedly connected to the rear end of the collection frame. A rectangular sealing ring that abuts against the outer wall of the housing is embedded in the front end of the sealing plate through a groove. A discharge pipe is connected to the lower end of the housing. A clamping mechanism is provided on the rear side of the box.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0018] Please see Figure 1-4A belt dryer for Chinese medicine that is easy to clean includes two connecting plates 1, two drive rollers 2 rotatably connected between the two connecting plates 1, and a stainless steel mesh belt 4 drivingly connected between the two drive rollers 2. A drive motor 3 with its output end fixedly connected to one of the drive rollers 2 is installed on the outer wall of the front connecting plate 1. A rinsing mechanism and a filtering mechanism are provided on the lower side of the two connecting plates 1. The rinsing mechanism includes a housing 6 fixedly connected to the lower end of two connecting plates 1. Two support rollers 7 are rotatably connected inside the housing 6. A stainless steel mesh belt 4 extends into the housing 6 and abuts against the outer wall of the two support rollers 7. A water pipe 8 is fixedly connected inside the housing 6. A diversion shell 9 is connected to the left and lower sides of the outer wall of the water pipe 8. Multiple first high-pressure nozzles 10 are connected to the left end of the left diversion shell 9, and multiple second high-pressure nozzles 11 are connected to the lower end of the lower diversion shell 9. A booster pump 28 with its water outlet connected to the inside of the water pipe 8 is installed on the outer wall of the housing 6. The filter mechanism passes through the through groove 15 at the rear end of the housing 6. A collection frame 16 extending into the housing 6 is inserted into the through groove 15. A filter screen 17 is fixedly connected inside the collection frame 16. A sealing plate 18 is fixedly connected to the rear end of the collection frame 16. A rectangular sealing ring 19 that abuts against the outer wall of the housing 6 is embedded in the front end of the sealing plate 18 through a groove. A discharge pipe 14 is connected to the lower end of the housing 6. A clamping mechanism is provided on the rear side of the housing 6.

[0019] In this embodiment: when the medicinal materials need to be dried, the drive motor 3 is started. The output end of the drive motor 3 drives the transmission roller 2 fixed to it to rotate, thereby driving the stainless steel mesh belt 4 to move between the two transmission rollers 2. The operator evenly spreads the medicinal materials to be dried on the upper working surface of the stainless steel mesh belt 4. As the stainless steel mesh belt 4 moves, the medicinal materials are transported to the drying area for heating and drying.

[0020] When the drying process is complete and the stainless steel mesh belt 4 needs to be cleaned, the drive motor 3 continues to operate, causing the stainless steel mesh belt 4 to run slowly. During transmission, the stainless steel mesh belt 4 enters the housing 6, and its transmission path is maintained by two support rollers 7. At the same time, the booster pump 28 is started, pumping external water into the water pipe 8. The water flow is then split into two diversion shells 9 on the left and lower sides. Finally, high-pressure water jets are sprayed from multiple first high-pressure nozzles 10 and multiple second high-pressure nozzles 11, thereby powerfully washing the stainless steel mesh belt 4 and washing away any adhering or embedded drug residues and other impurities.

[0021] The flushed wastewater and impurities fall into the collection frame 16. Before being discharged, the wastewater flows through the filter screen 17, where impurities are trapped and collected inside the collection frame 16. The filtered water is then discharged through the drain pipe 14 at the bottom of the housing 6. To ensure the airtightness of the housing 6 during the cleaning process and prevent wastewater leakage, a pressing mechanism applies leftward pressure to the sealing plate 18, ensuring a tight fit between the rectangular sealing ring 19 and the housing 6, thus preventing wastewater leakage.

[0022] In summary, this facilitates the cleaning of the stainless steel mesh belt 4 after the drying process, thereby avoiding mesh blockage, microbial growth, and cross-contamination between different batches of medicinal materials.

[0023] As a technical optimization of this utility model, the clamping mechanism includes a rotating column 20 rotatably connected to the rear end of the housing 6, a movable plate 21 fixedly connected to the other end of the rotating column 20, a screw 22 threadedly connected to the outer wall of the movable plate 21, a limiting groove opened at the rear end of the sealing plate 18, a pressure plate 23 extending into the limiting groove rotatably connected to the front end of the screw 22, a handwheel fixedly connected to the rear end of the screw 22, and a slide rod 24 slidably connected to the rear end of the pressure plate 23, which passes through the movable plate 21 and is slidably connected to the movable plate 21.

[0024] In this embodiment: when the collection frame 16 needs to be installed, the collection frame 16 is inserted into the inside of the box 6 through the groove 15, and the positioning strip 26 is inserted into the inside of the positioning groove 25. Then, the movable plate 21 is rotated around the rotating column 20 to align the pressure plate 23 with the limiting groove. Then, the handwheel is turned to drive the screw 22 to rotate forward and push the pressure plate 23 to move forward until the pressure plate 23 is tightly pressed into the limiting groove. The rectangular sealing ring 19 at the front end of the sealing plate 18 is tightly fitted to the outer wall of the box 6 under pressure, thereby achieving a reliable seal. When it is necessary to disassemble the collection frame 16, loosen the screw 22 by turning the handwheel, and move the pressure plate 23 backward by the guiding action of the slide bar 24 until the pressure plate 23 is disengaged from the limiting groove. Then the movable plate 21 can be rotated around the rotating column 20 to make the movable plate 21 and the sealing plate 18 misaligned. Then the collection frame 16 can be easily pulled out from the through groove 15 for cleaning, which is very convenient for maintenance.

[0025] As a technical optimization of this utility model, two positioning rollers 5 are rotatably connected between the two connecting plates 1, and both positioning rollers 5 abut against the outer wall of the stainless steel mesh belt 4.

[0026] In this embodiment, two positioning rollers 5 are set to guide and maintain the transmission path of the stainless steel mesh belt 4.

[0027] As a technical optimization of this utility model, the multiple first high-pressure nozzles 10 and the multiple second high-pressure nozzles 11 are staggered in the front-to-back direction.

[0028] In this embodiment: by setting multiple first high-pressure nozzles 10 and second high-pressure nozzles 11 to be staggered in the front-to-back direction, the high-pressure water jets sprayed from both sides form a cross-coverage in space. This layout ensures that the mesh and surface of the stainless steel mesh belt 4 can be fully impacted by the water flow.

[0029] As a technical optimization of this utility model, a frame 12 is fixedly connected to the upper end of the two connecting plates 1. Multiple infrared radiation heating tubes 13 are arranged inside the frame 12. A hollow plate is fixedly connected through the rear end of the frame 12. A dehumidifier with an air inlet extending into the hollow plate is installed at the upper end of the hollow plate. Multiple air inlet pipes are connected to the front end of the hollow plate.

[0030] In this embodiment: Multiple infrared radiation heating tubes 13 are activated, emitting infrared rays to heat the medicinal materials and evaporate the moisture. At the same time, a dehumidifier at the rear end of the frame 12 is activated, continuously extracting the high-humidity air generated during the drying process through the hollow plate and air inlet pipe, thereby maintaining a low-humidity environment in the drying area.

[0031] As a technical optimization of this utility model, positioning grooves 25 are provided at both the left and right ends of the collection frame 16, and positioning strips 26 that are fixedly connected to the inner wall of the box 6 are inserted into the two positioning grooves 25.

[0032] In this embodiment: when the collection frame 16 is inserted into the through slot 15 of the box 6, the positioning slots 25 at both ends are fitted onto the positioning strip 26 fixedly connected to the inner wall of the box 6. This method provides a positioning effect for the installation of the collection frame 16.

[0033] As a technical optimization of this utility model, two fixing plates 27 are fixedly connected between the lower ends of the two connecting plates 1, and two support legs are fixedly connected to the lower ends of the two fixing plates 27.

[0034] In this embodiment: by setting two fixing plates 27, the two connecting plates 1 are connected and fixed, and multiple legs provide support for the device.

[0035] The working principle and usage process of this utility model are as follows: When it is necessary to dry medicinal materials, the drive motor 3 is started. The output end of the drive motor 3 drives the transmission roller 2 fixed to it to rotate, which in turn drives the stainless steel mesh belt 4 to move between the two transmission rollers 2. The operator evenly spreads the medicinal materials to be dried on the upper working surface of the stainless steel mesh belt 4. As the stainless steel mesh belt 4 moves, the medicinal materials are transported to the drying area inside the frame 12. At this time, multiple infrared radiation heating tubes 13 are activated, which emit infrared rays to heat the medicinal materials and evaporate the moisture in them. At the same time, the dehumidifier at the rear end of the frame 12 is started, continuously extracting the high humidity air generated during the drying process through the hollow plate and the air inlet pipe, thereby maintaining a low humidity environment in the drying area.

[0036] When the drying process is complete and the stainless steel mesh belt 4 needs to be cleaned, the drive motor 3 continues to operate, causing the stainless steel mesh belt 4 to run slowly. During transmission, the stainless steel mesh belt 4 enters the housing 6, and its transmission path is maintained by two support rollers 7. At the same time, the booster pump 28 is started, pumping external water into the water pipe 8. The water flow is then split into two diversion shells 9 on the left and lower sides. Finally, high-pressure water jets are sprayed from multiple first high-pressure nozzles 10 and multiple second high-pressure nozzles 11, thereby powerfully washing the stainless steel mesh belt 4 and washing away any adhering or embedded drug residues and other impurities.

[0037] The flushed wastewater and impurities fall into the collection frame 16. Before being discharged, the wastewater flows through the filter screen 17, where impurities are trapped and collected inside the collection frame 16. The filtered water is then discharged through the drain pipe 14 at the bottom of the housing 6. To ensure the airtightness of the housing 6 during the cleaning process and prevent wastewater leakage, a pressing mechanism applies leftward pressure to the sealing plate 18, ensuring a tight fit between the rectangular sealing ring 19 and the housing 6, thus preventing wastewater leakage.

[0038] When cleaning is finished and impurities need to be removed, simply loosen the screw 22 by handwheeling. The pressure plate 23 will move backward under the guidance of the slide bar 24 until the pressure plate 23 disengages from the limiting groove. Then, the movable plate 21 can be rotated around the rotating column 20 to separate the movable plate 21 from the sealing plate 18. The collection frame 16 can then be easily pulled out from the through groove 15 for cleaning, making maintenance very convenient.

[0039] It should be noted that a vertical plate is installed on the upper part of the frame 12, and a controller, thermostat and operation panel are installed on its outer wall. The operation panel serves as a human-machine interface for setting parameters. The controller receives instructions from the operation panel to control the operation of the drive motor 3, the booster pump 28, the dehumidifier and the power supply of the infrared radiation heating tube 13. When the infrared radiation heating tube 13 is started by the controller, the thermostat can adjust the heating power of the infrared radiation heating tube 13.
