Description

Technical Field

[0001] This invention belongs to the technical field of traditional Chinese medicine processing equipment, specifically relating to a traditional Chinese medicine cleaning device and its usage method. Background Technology

[0002] Traditional Chinese medicine (TCM) is an important component of TCM, primarily derived from plants, animals, and minerals. The traditional process involves washing, drying, and chopping or grinding the raw materials according to specific particle requirements, then decocting them in a certain proportion to prepare a decoction or pills. Modern TCM preparations require large-scale, rapid formulation using mechanized pharmaceutical equipment. Because the raw materials are derived from the natural environment, their surfaces often contain dirt, dust, and other contaminants. Furthermore, different herbs have varying degrees of dirt and different shapes and sizes, making it impossible to effectively clean all herbs using the same cleaning equipment. For example, root-type Chinese medicinal herbs are often covered with a large amount of mud or gravel, and are large in size, long and thick in shape, and tough in texture. Therefore, they require equipment with stronger cleaning capabilities and a more powerful water flow during cleaning. Leafy, flower-type, and some animal tissue-type Chinese medicinal herbs have less dirt, are smaller in size, and are delicate and easily damaged. Therefore, they require a moderate water flow during cleaning. Furthermore, the length of time the Chinese medicinal herbs remain in the cleaning equipment is crucial to their cleanliness. Existing drum-type Chinese medicinal herb cleaning equipment uses a continuous input and output method, which is efficient, but it cannot adjust the retention time of the herbs within a certain operating time according to the different herbs. The cleaning effect can only be enhanced by extending the operating time or performing multiple cleaning cycles, which reduces efficiency and increases costs. Summary of the Invention

[0003] The purpose of this invention is to address the problems in existing Chinese herbal medicine cleaning equipment, such as the inability to employ differentiated rinsing methods for different herbs, thus affecting cleaning effectiveness, and the inability of drum-type herbal medicine cleaning equipment to adjust the dwell time of herbs according to their size. This invention proposes a new Chinese herbal medicine cleaning device and its usage method. This invention allows for the selection of different cleaning methods based on different herbs, effectively cleaning dirt from the herbs. Furthermore, it allows for adjustment of the effective cleaning time according to the size of the herbs, enhancing the cleaning effect.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A Chinese medicinal herb cleaning device includes a chassis and a cleaning channel; the cleaning channel extends through the chassis, with a feed chute at the inlet and a discharge chute at the outlet; a cleaning drum is installed inside the cleaning channel; the cleaning drum is connected to a rotating mechanism; a cleaning pipe assembly is installed above the interior of the cleaning drum; ordinary cleaning nozzles and cavitation cleaning nozzles are distributed on the cleaning pipe assembly; a resonant cavity is provided inside the cavitation cleaning nozzle; oscillating blades are also distributed inside the cleaning drum; several oscillating blades are arranged at an angle; one end of the bottom of each oscillating blade is hinged to the cleaning drum, and the other end is provided with a crown gear; each row of oscillating blades is provided with a corresponding adjusting rod; spur gears are distributed on the adjusting rods; each set of crown gears is arranged at an angle with the corresponding oscillating blade; each set of crown gears meshes with a set of spur gears; one end of the adjusting rod extends out of the cleaning channel.

[0006] The feeding trough is equipped with a ramp facing the cleaning channel to feed the Chinese medicinal materials into the cleaning drum within the cleaning channel. The rotation of the cleaning drum causes the Chinese medicinal materials to tumble and be thrown up. The cleaning drum has a certain inclination, allowing the materials to move towards the outlet. The rotating mechanism drives the cleaning drum to rotate. The cleaning pipe assembly supplies water and sprays water into the cleaning drum through the ordinary cleaning nozzle and the cavitation cleaning nozzle, thereby cleaning the Chinese medicinal materials. The resonant cavity of the cavitation cleaning nozzle can be a Helmholtz-type nozzle, which cavitates the water flow. The cavitated water flow impacts the adhering substances on the Chinese medicinal materials with high-frequency water flow and micro-jet, easily removing dirt from roots and other Chinese medicinal materials. The oscillating blades obstruct the Chinese medicinal materials, increasing their time in the cleaning drum. The oscillating blades are tilted towards the outlet of the cleaning channel, acting as a guide, allowing the Chinese medicinal materials to move towards the outlet while rolling. When cleaning smaller Chinese medicinal materials with less dirt, such as leaves and small branches, excessive rinsing is not required. For cleaning large medicinal herbs, such as tree roots, a stronger cleaning force and a more effective cleaning effect are required. Since these herbs are smaller and tend to slide out of the cleaning drum, the angle between the oscillating blades and the drum needs to be reduced to make the blades more upright, while maintaining a certain angle of inclination to avoid obstructing the herbs. For larger herbs, such as tree roots, which have more attached dirt and grime, both the regular and cavitation cleaning nozzles need to be activated simultaneously. Because of their larger size and weight, these herbs spend more time in the cleaning drum than smaller ones. Therefore, the angle between the oscillating blades and the drum should be increased to make the blades more inclined, providing some obstruction while guiding the herbs towards the cleaning channel's outlet. Rotating the adjusting rod causes the spur gear to drive the crown gear, which in turn rotates the oscillating blades, allowing the angle of inclination to be adjusted according to the type of herb. One end of the adjusting rod extends outside the cleaning channel for easy rotation by the user.

[0007] As a further technical improvement, the cleaning pipeline assembly includes cleaning pipeline I and cleaning pipeline II. Both cleaning pipeline I and cleaning pipeline II extend from the inlet of the cleaning drum into the drum, then bend at the outlet of the drum before re-entering and extending back to the inlet before closing. Ordinary cleaning nozzles are distributed on cleaning pipeline I; cavitation cleaning nozzles are distributed on cleaning pipeline II. Both cleaning pipeline I and cleaning pipeline II are equipped with valves. This design ensures that both cleaning pipeline I and cleaning pipeline II bend back once within the cleaning drum, increasing the effective number of ordinary and cavitation cleaning nozzles and enhancing the cleaning effect. The valves on cleaning pipeline I and cleaning pipeline II can independently control the on / off state of cleaning pipeline I and cleaning pipeline II, and can also control the water flow rate.

[0008] As a further technical improvement, the inner wall of the cleaning drum is provided with drainage holes; a water receiving tray is provided below the cleaning drum; and a drain pipe is connected to the water receiving tray. The drainage holes allow the cleaning water inside the cleaning drum to be discharged into the water receiving tray, and then discharged into a sewage ditch or similar facility through the drain pipe.

[0009] As a further technical improvement, the rotating mechanism includes a rotating gear ring and a rotating gear; the rotating gear ring is arranged around the outer circumference of the cleaning drum; the rotating gear meshes with the rotating gear ring; the rotating gear is connected to a rotating motor. The rotating motor drives the rotating gear to rotate, thereby driving the rotating gear ring to rotate, and finally causing the cleaning drum to rotate.

[0010] As a further technical improvement, a hinge is provided at the bottom of the oscillating blade on the side away from the crown gear; the oscillating blade is hinged to the cleaning drum via the hinge. The oscillating blade swings via the hinge.

[0011] As a further technical improvement, a connecting block is also included; one end of the connecting block is connected to the outside of the cleaning pipe assembly, and the other end is connected to the chassis. The connecting block is used to fix the cleaning pipe assembly.

[0012] As a further technical improvement, the chassis is provided with a maintenance side door. The maintenance door allows for internal maintenance of the equipment.

[0013] As a further technical improvement, the bottom of the chassis is equipped with casters.

[0014] The above-described method for using the Chinese herbal medicine cleaning equipment:

[0015] Cleaning Small-Volume Herbs: When cleaning herbs with small unit volumes, first rotate the adjusting rod; this causes the spur gear to drive the crown gear to rotate, adjusting the angle between the swing blades and the cleaning drum to 100°~120°. At this angle, small-particle herbs are less likely to be thrown out by the rotating cleaning drum, increasing the time the herbs spend in the cleaning drum. Pour the herbs from the feed trough into the cleaning channel, where they enter the cleaning drum. Open the valve on cleaning pipe I, and the ordinary cleaning nozzles spray cleaning water downwards. Turn on the rotating mechanism, and the cleaning drum rotates, throwing the herbs upwards as it rotates, and gradually rinsing them clean under the ordinary cleaning nozzles. Due to the inclined arrangement of the swing blades, under the action of the inclined direction of the swing blades and the centrifugal force of the cleaning drum, the herbs are gradually sent to the outlet of the cleaning channel and finally fall into the discharge trough, completing the cleaning process. The cleaning water flows from the drain hole of the cleaning drum into the water receiving tray and is discharged from the drain pipe.

[0016] Cleaning large-volume medicinal materials: When cleaning large-volume medicinal materials, first rotate the adjusting rod to make the spur gear drive the crown gear to rotate, and adjust the angle between the swing blade and the cleaning drum to 120°~160°. At this angle, the large-volume medicinal materials will not be stuck and can be blocked, thus extending the cleaning time of the large-volume medicinal materials in the cleaning drum. Pour the medicinal materials from the feed trough into the cleaning channel, and the medicinal materials enter the cleaning drum. Open the valve on cleaning pipe I, and the ordinary cleaning nozzle sprays cleaning water downwards. Open the valve on cleaning pipe II, and the cavitation cleaning nozzle sprays cavitation jets downwards. When the cavitation jets hit the medicinal materials, the bubbles in the jets burst, generating pressure and micro-jet, which knocks off the soil and dirt attached to the roots and other medicinal materials. At the same time, turn on the rotating mechanism, and the cleaning drum rotates, and the medicinal materials are rotated, cleaned, and discharged in the same way as in the above steps.

[0017] The technical solution of this invention has the following beneficial effects:

[0018] 1. By setting up both ordinary cleaning nozzles and cavitation cleaning nozzles, this invention can enhance the rinsing effect when cleaning different Chinese medicinal materials, based on the actual condition of the materials, and ensure that different Chinese medicinal materials achieve the best cleaning effect without damaging them.

[0019] 2. The present invention uses a swing blade with adjustable swing amplitude, which can swing the blade at an appropriate amplitude according to the medicinal materials being cleaned, blocking the medicinal materials and allowing different medicinal materials to remain in the cleaning drum for a sufficient time, thereby increasing the cleaning time and ensuring that the medicinal materials are cleaned thoroughly.

[0020] 3. The cleaning pipe I and cleaning pipe II of the present invention are bent back and forth inside the cleaning drum, which increases the number of ordinary cleaning nozzles and cavitation cleaning nozzles that can be arranged, thereby increasing the rinsing range of Chinese medicinal materials and improving the cleaning effect.
