Description

Technical Field

[0001] The invention belongs to the technical field of Chinese medicinal material cleaning devices, and in particular relates to an impurity-removing and cleaning device for preventing medicinal materials from being damaged. Background Art

[0002] For a large number of block-shaped medicinal materials, such as Gastrodia elata, Panax notoginseng and other stem-shaped medicinal materials, their texture is relatively hard, and due to the planting environment, there is usually a lot of mud and sand attached to their surface. Before deep processing of stem-shaped medicinal materials, the mud and sand on the surface of the medicinal materials need to be removed.

[0003] The existing methods of cleaning block medicinal materials mainly include manual cleaning and machine cleaning. Manual cleaning is to manually scrub the surface of the medicinal materials, which is very labor-intensive, and the cleaning efficiency is low and the cleaning effect is not ideal. The existing machine cleaning of block herbs is mainly to set a high-speed stirring device in the box or pool, and set a relatively hard brush on the outside of the stirring device, and use the high-speed rotating brush to clean the mud and sand on the surface of the medicinal materials. However, the existing machine cleaning method has the problem of too fast rotation speed and too much force on the surface of the medicinal materials, which can easily cause damage to the medicinal materials, thereby affecting the medicinal properties of the medicinal materials.

[0004] Therefore, in view of the problems of low efficiency and poor cleaning effect in the existing manual cleaning of medicinal materials, and the problem of easy damage to medicinal materials in the existing machine cleaning of medicinal materials, the present invention discloses an impurity removal and cleaning device that prevents damage to medicinal materials. Summary of the invention

[0005] The object of the present invention is to provide an impurity removal and cleaning device for preventing damage to medicinal materials, which can perform flexible kneading and pressing cleaning, vibration fine cleaning, and cyclone impurity removal washing operations on the medicinal materials, while effectively avoiding damage to the medicinal materials during the washing process.

[0006] The present invention is achieved through the following technical solutions:

[0007] A cleaning device for preventing medicinal materials from being damaged comprises a mounting bracket, on which a flexible kneading cleaning device, a vibrating fine cleaning device and a cyclone impurity removing device connected in sequence are arranged from top to bottom, the flexible kneading cleaning device comprises a rotatable kneading cylinder, a plurality of planetary flexible rollers are arranged inside the kneading cylinder, a flexible layer is arranged on the inner wall of the kneading cylinder, and the planetary flexible rollers cooperate with the flexible layer on the inner wall of the kneading cylinder to knead the medicinal materials; the vibrating fine cleaning device comprises a fine cleaning cylinder, the inlet end of the fine cleaning cylinder is connected to the outlet end of the kneading cylinder through an electric control valve, an ultrasonic vibration device and a plurality of ceramic particles with built-in metal cores are arranged inside the fine cleaning cylinder; the cyclone impurity removing device comprises a cyclone barrel, the inlet end of the cyclone barrel is connected to the outlet end of the fine cleaning cylinder through an electric control valve, a spiral flow channel is arranged inside the cyclone barrel, a ceramic particle recovery chamber is arranged on one side of the outlet end of the spiral flow channel, an electromagnetic adsorption component is arranged inside the ceramic particle recovery chamber, and solid impurity removal ports are respectively arranged on the other side of the outlet end of the spiral flow channel.

[0008] The top of the kneading cylinder is provided with a medicinal material inlet and a cleaning water inlet, the bottom of the kneading cylinder is the outlet and is connected to the top of the fine washing cylinder, the bottom of the fine washing cylinder is the outlet and is connected to the top of the swirl barrel, and the bottom of the swirl barrel is the medicinal material outlet. The medicinal materials are added to the kneading cylinder, and the rotation of the kneading cylinder drives the planetary flexible roller inside it to rotate relative to the kneading cylinder. When the planetary flexible roller rotates, the medicinal materials and the cleaning water inside the kneading cylinder are stirred. During the stirring process, the medicinal materials pass between the planetary flexible roller and the flexible layer on the inner wall of the kneading cylinder, and then the medicinal materials are flexibly kneaded to peel off large particles of mud and other impurities attached to the surface of the medicinal materials. Since the rotation speed of the planetary flexible roller is lower than that of the traditional stirring device, and the planetary flexible roller is in flexible contact with the medicinal materials, the medicinal materials will not be scratched.

[0009] It should be noted that the above kneading will not cause damage to the medicinal materials themselves, but only remove large particles of mud and sand impurities attached to the surface of the medicinal materials through flexible kneading.

[0010] After a period of kneading, the electric control valve between the kneading cylinder and the fine washing cylinder is opened, so that the medicinal materials inside the kneading cylinder fall into the fine washing cylinder for further cleaning. The ultrasonic vibration device inside the fine washing cylinder applies high-frequency vibration to the medicinal materials, and at the same time, the vibration drives the ceramic particles inside the fine washing cylinder to contact the surface of the medicinal materials. After the tiny mud and sand particles attached to the surface of the medicinal materials are knocked loose by the ceramic particles, the tiny mud and sand particles on the surface of the medicinal materials can be smoothly peeled off by the ultrasonic vibration device. The combination of vibration and ceramic particles replaces the traditional method of cleaning the surface of the medicinal materials by rotating the brush, which can not only ensure the cleaning effect of the medicinal materials, but also avoid damage to the surface of the medicinal materials caused by the high-speed rotating brush.

[0011] After the fine washing of the medicinal materials is completed, the electric control valve between the fine washing cylinder and the cyclone cylinder is opened, so that the medicinal materials and ceramic particles fall into the cyclone cylinder synchronously. Clean water flow is introduced to the top side of the cyclone cylinder for the final washing of the medicinal materials inside the cyclone cylinder. The introduced water flow forms a vortex under the action of the spiral flow channel inside the cyclone cylinder, and the medicinal materials are driven to spirally move in the cyclone cylinder through the vortex. Due to the centrifugal force brought by the spiral flow, impurities such as mud and sand with a specific gravity greater than that of the medicinal materials are separated from the medicinal materials. The separated mud and sand are deposited at the solid impurity removal port at the bottom of the cyclone barrel for discharge, and the metal core of the ceramic particles in the washing water is attracted by the magnetic force of the electromagnetic adsorption component during the cyclone process, and then deposited inside the ceramic particle recovery chamber for reuse in the fine washing cylinder. The medicinal materials after the impurities are separated are discharged through the medicinal material outlet at the bottom of the cyclone cylinder for subsequent drying.

[0012] In order to better realize the present invention, further, a ceramic particle return device is arranged between the inlet end of the fine washing cylinder and the ceramic particle recovery chamber of the cyclone cylinder. The ceramic particle return device can send the ceramic particles deposited in the ceramic particle recovery chamber to the fine washing cylinder to re-participate in the fine washing process of the medicinal materials.

[0013] In order to better realize the present invention, further, the ceramic particle return device includes a screw conveyor, a spray device, and a return cylinder. The return cylinder is arranged between the inlet end of the fine washing cylinder and the ceramic particle recovery chamber of the cyclone cylinder. The interior of the return cylinder is provided with a screw conveyor for feeding toward the inlet end of the fine washing cylinder, and the interior of the return cylinder is provided with a spray device corresponding to the conveying part of the screw conveyor.

[0014] In order to better realize the present invention, further, a sediment deposition tank is provided at the bottom of the return tube, and a discharge port is provided on one side of the sediment deposition tank. A small amount of sediment mixed in the ceramic particles is separated from the ceramic particles under the washing of the spray device and deposited in the sediment deposition tank at the bottom of the return tube, and then the sediment can be discharged through the discharge port.

[0015] In order to better realize the present invention, further, the kneading cylinder includes an inner cylinder and an outer cylinder that rotate asynchronously, a radial sliding rod is circumferentially arranged on the top of the inner cylinder, a slider is slidably sleeved on the radial sliding rod, the slider is connected to the top of the inner cylinder through a crank connecting rod, and a planetary flexible roller is rotatably arranged at the bottom of the slider; flexible layers are arranged on the cylinder walls of the inner cylinder and the outer cylinder, and the planetary flexible rollers reciprocate between the cylinder walls of the inner cylinder and the outer cylinder as the inner cylinder rotates.

[0016] When the inner cylinder rotates, the crank connecting rod drives the slider to slide back and forth along the radial sliding rod, thereby driving the planetary flexible roller to move back and forth between the inner cylinder and the outer cylinder, so that when the planetary flexible roller rotates, the flexible roller wall of the planetary flexible roller can periodically contact the cylinder wall of the inner cylinder and the cylinder wall of the outer cylinder respectively to knead the medicinal materials.

[0017] In order to better implement the present invention, further, the top of the inner cylinder is provided with an outer gear ring, the top of the outer cylinder is provided with an inner gear ring, and the top of the planetary flexible roller is provided with a planetary gear meshing with the inner gear ring and the outer gear ring.

[0018] In order to better realize the present invention, further, a magnetic stirring rotor is rotatably arranged inside the fine washing cylinder, and a magnetic generator is arranged outside the fine washing cylinder to drive the magnetic stirring rotor to rotate by magnetic force.

[0019] In order to better implement the present invention, further, a plurality of flexible scrapers are arranged at intervals on the spiral flow channel along the swirl direction, and flexible bristles are arranged on the flexible scrapers.

[0020] In order to better implement the present invention, further, the electromagnetic adsorption member includes a plurality of electromagnetic adsorption plates arranged at intervals, and a water flow channel is provided between adjacent electromagnetic adsorption plates.

[0021] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0022] (1) The present invention provides an inner cylinder and an outer cylinder that rotate relative to each other, and provides a plurality of planetary flexible rollers that can reciprocate between the inner cylinder and the outer cylinder along the circumferential direction between the inner cylinder and the outer cylinder. The medicinal materials are stirred by the rotation of the planetary flexible rollers. At the same time, the planetary flexible rollers periodically contact the flexible layer on the cylinder wall of the inner cylinder and the flexible layer on the cylinder wall of the outer cylinder, thereby performing flexible kneading and cleaning on the medicinal materials, thereby quickly removing large particles of mud and sand impurities on the surface of the medicinal materials and effectively avoiding damage to the medicinal materials.

[0023] (2) The present invention provides a fine washing cylinder, and provides an ultrasonic vibration device and ceramic particles containing a metal inner core inside the fine washing cylinder. The ultrasonic vibration device drives the medicinal materials and ceramic particles in the washing water to vibrate, so that the ceramic particles impact the surface of the medicinal materials, so that the fine sand particles on the surface of the medicinal materials are loosened. The fine sand on the surface of the medicinal materials can be effectively removed by the high-frequency vibration of the washing water. At the same time, the lightweight ceramic particles will not produce too much impact force on the surface of the medicinal materials, thereby further avoiding damage to the medicinal materials while ensuring the cleaning effect.

[0024] (3) The present invention provides a cyclone cylinder, and forms a cyclone through the spiral flow channel inside the cyclone cylinder. The cyclone drives the medicinal materials to flow in a spiral. The centrifugal force generated by the cyclone separates the mud, ceramic particles and medicinal materials with different specific gravities, thereby achieving efficient impurity removal of the medicinal materials and recovery of the ceramic particles, and significantly improving the efficiency of medicinal material cleaning and impurity removal and separation.

DETAILED DESCRIPTION

[0031] Embodiment 1:

[0032] The present embodiment is a cleaning device for preventing damage to medicinal materials, such as Figure 1-Figure 5 As shown, it includes a mounting bracket 1, on which a flexible kneading and cleaning device 2, a vibrating fine cleaning device 3, and a cyclone impurity removal device 4 are sequentially connected from top to bottom. The flexible kneading and cleaning device 2 includes a rotatable kneading cylinder 21, and a plurality of planetary flexible rollers 22 are arranged inside the kneading cylinder 21. A flexible layer is arranged on the inner wall of the kneading cylinder 21, and the planetary flexible rollers 22 cooperate with the flexible layer on the inner wall of the kneading cylinder 21 to knead the medicinal materials; the vibrating fine cleaning device 3 includes a fine cleaning cylinder 31, and the inlet end of the fine cleaning cylinder 31 is connected through an electric control valve. The door is connected to the outlet end of the kneading cylinder 21, and the interior of the fine washing cylinder 31 is provided with an ultrasonic vibration device 32 and a plurality of ceramic particles 33 with a built-in metal core; the cyclone impurity removal device 4 comprises a cyclone barrel 41, and the inlet end of the cyclone cylinder 41 is connected to the outlet end of the fine washing cylinder 31 through an electric control valve, and the interior of the cyclone cylinder 41 is provided with a spiral flow channel 42, and a ceramic particle recovery chamber is provided on one side of the outlet end of the spiral flow channel 42, and an electromagnetic adsorption component 43 is provided inside the ceramic particle recovery chamber, and solid impurity removal ports are respectively provided on the other side of the outlet end of the spiral flow channel 42.

[0033] Water is injected into the kneading cylinder 21 through the water inlet at the top of the kneading cylinder 21 to a water level of half the cylinder depth, so as to pre-soak the medicinal materials inside the kneading cylinder 21. After pre-soaking for 10-15 minutes, the kneading cylinder 21 is driven to rotate by the driving motor, and the meshing structure between the kneading cylinder 21 and the planetary flexible roller 22 drives the planetary flexible roller 22 to perform planetary rotation inside the kneading cylinder 21 with the axis of the kneading cylinder 21 as the rotation axis. The medicinal materials inside the kneading cylinder 21 are stirred by the rotating planetary flexible roller 22, so as to further loosen the mud and sand on the surface of the medicinal materials. At the same time, during the rotation process, the medicinal materials are passed between the planetary flexible roller 22 and the flexible layer on the cylinder wall of the kneading cylinder 21, so as to knead the medicinal materials. The kneading time is 20-30 minutes, and the rotation speed of the planetary flexible roller 22 is less than or equal to 600 rad / min, so as to avoid the medicinal materials from being damaged by violent collision with the planetary flexible roller 22 due to excessive rotation speed. An electrically controlled drain valve is provided on one side of the bottom of the kneading cylinder 21. During the kneading process, the electrically controlled drain valve is opened periodically to discharge the washing water inside the kneading cylinder 21. At the same time, the washing water is periodically replenished into the kneading cylinder 21 through the water inlet at the top of the kneading cylinder 21, so that the washing water inside the kneading cylinder 21 is partially replaced and a certain water level is maintained.

[0034] Furthermore, the flexible layer on the wall of the kneading cylinder 21 is made of flexible rubber or flexible sponge, and a flexible layer is also provided on the roller wall of the planetary flexible roller 22. After long-term use, the worn flexible layer can be removed and replaced to ensure the flexible kneading effect on the medicinal materials.

[0035] After kneading, the washing water inside the kneading cylinder 21 is drained through the drain valve on one side of the bottom of the kneading cylinder 21. At this time, most of the mud and sand peeled off from the medicinal materials are deposited in the sedimentation tank at the bottom of the kneading cylinder 21. Then the electric control valve between the kneading cylinder 21 and the fine washing cylinder 31 is opened to allow the medicinal materials to enter the fine washing cylinder 31. A water inlet is provided at the top of the fine washing cylinder 31, and an electric control drain valve is provided on one side of the bottom of the fine washing cylinder 31. Washing water is injected into the fine washing cylinder 31 through the water inlet so that the water level inside the fine washing cylinder 31 is greater than or equal to half the depth of the cylinder. Then the ultrasonic vibration device 32 is turned on, and the medicinal materials and ceramic particles 33 in the washing water are driven by the ultrasonic vibration device 32 to vibrate at high frequency. Through the collision between the ceramic particles 33 and the surface of the medicinal materials, the small particles of mud and sand on the surface of the medicinal materials are impacted and loosened, and the fine mud and sand on the surface of the medicinal materials can be removed by the vibration of the washing water. During the fine washing process, the electrically controlled drain valve is periodically opened to discharge the washing water in the fine washing cylinder 31, and at the same time, the washing water is periodically added to the fine washing cylinder 31 through the water inlet at the top of the fine washing cylinder 31, so that the washing water in the fine washing cylinder 31 is partially replaced and a certain water level is maintained. After the medicinal materials are finely washed for 15min-20min, the ultrasonic vibration device 32 is stopped, and then the medicinal materials are kept still in the fine washing cylinder 31 for 5min-10min, so that the fine sand is deposited in the sedimentation tank at the bottom of the fine washing cylinder 31, and then the washing water in the fine washing cylinder 31 is drained through the electrically controlled drain valve.

[0036] Furthermore, in order to prevent the ceramic particles 33 from damaging the surface of the medicinal material, the shape of the ceramic particles 33 is set to be a round sphere or ellipsoid, and a flexible sponge layer is coated on the surface of the ceramic particles 33 to cushion the impact.

[0037] The electric control valve between the fine washing cylinder 31 and the cyclone cylinder 41 is opened to allow the medicinal materials to enter the cyclone cylinder 41. A water inlet is provided at the top of the cyclone cylinder 41 along the tangent direction of the cylinder wall. Washing water is injected into the cyclone cylinder 41 through the water inlet, and the washing water is spirally flowed under the action of the spiral flow channel 42 inside the cyclone cylinder 41, thereby driving the medicinal materials to spirally flow inside the cyclone cylinder 41. The centrifugal force generated by the cyclone action separates the medicinal materials, mud and sand impurities, and ceramic particles 33. The specific gravity of mud and sand>the specific gravity of ceramic particles>the specific gravity of medicinal materials. Under the action of the centrifugal force of the cyclone, the mud and sand impurities with the largest specific gravity are centrifuged to the outermost layer and deposited in the solid impurity removal port at the bottom of the cyclone cylinder 41. The ceramic particles 33 with medium specific gravity are centrifuged to the ceramic particle recovery chamber under the centrifugal force and the electromagnetic adsorption of the electromagnetic adsorption member 43 for collection and reuse in the fine washing cylinder 31. The medicinal materials with the lightest specific gravity are discharged through the medicinal material outlet at the bottom of the cyclone cylinder 41.

[0038] Embodiment 2:

[0039] This embodiment is further optimized based on the above embodiment 1. Figure 5As shown, a ceramic particle return device 5 is provided between the inlet end of the fine washing cylinder 31 and the ceramic particle recovery chamber of the cyclone cylinder 41 .

[0040] The ceramic particle return device 5 includes a screw conveyor 51, a spray device 52, and a return cylinder 53. The return cylinder 53 is arranged between the inlet end of the fine washing cylinder 31 and the ceramic particle recovery chamber of the cyclone cylinder 41. The interior of the return cylinder 53 is provided with a screw conveyor 51 that feeds toward the inlet end of the fine washing cylinder 31, and the interior of the return cylinder 53 is provided with a spray device 52 corresponding to the conveying part of the screw conveyor 51.

[0041] The ceramic particles 33 deposited in the ceramic particle recovery chamber are sent back to the fine washing cylinder 31 by the screw conveyor 51 to participate in the fine washing of the medicinal materials again. At the same time, in the process of the screw conveyor 51 sending the ceramic particles 33 back upward, the spray device 52 sprays and washes the trace sediment on the surface of the ceramic particles 33 to avoid sending the sediment back to the fine washing cylinder 31.

[0042] Furthermore, micropores are provided on the spiral conveying blades of the screw conveyor 51 to form a filtering structure, so that the tiny mud and sand washed off by the spray device 52 can fall to the bottom of the return cylinder 53 through the micropores. The diameter of the ceramic particles 33 is larger than the micropores, so they are returned upward to the fine washing cylinder 31 along with the rotation of the spiral conveying blades.

[0043] A sediment sedimentation trough is provided at the bottom of the return tube 53 , and a discharge port is provided at one side of the sediment sedimentation trough.

[0044] The other parts of this embodiment are the same as those of Embodiment 1, and thus will not be described in detail.

[0045] Embodiment 3:

[0047] Six groups of planetary flexible rollers 22 are evenly arranged along the circumferential direction between the inner cylinder 211 and the outer cylinder 212, and the ends of the rotating shafts of the planetary flexible rollers 22 are rotatably connected to the bottom of the slider. A first driving motor is arranged on the top of the mounting bracket 1 to drive the inner cylinder 211 to rotate, and a turntable is arranged on the top of the inner cylinder 211. The edge of the turntable is rotatably hinged to one end of a crank connecting rod, and the other end of the crank connecting rod is rotatably hinged to the top of the slider.

[0048] A driving gear ring and a second driving motor are arranged on the outer side of the bottom of the outer drum 212. The output shaft of the second driving motor meshes with the outer gear ring through the driving gear, thereby driving the outer drum 212 to rotate. In order to improve the kneading and washing effect, the rotation direction of the outer drum 212 is opposite to that of the inner drum 211.

[0049] The rotation of the inner cylinder 211 drives the crank connecting rod to drive the slider to move back and forth between the inner cylinder 211 and the outer cylinder 212 along the radial sliding rod 213, thereby driving the planetary flexible roller 22 to move back and forth between the inner cylinder 211 and the outer cylinder 212, so that the flexible roller wall of the planetary flexible roller 22 is in periodic contact with the flexible layer on the cylinder wall of the inner cylinder 211 and the flexible layer on the cylinder wall of the outer cylinder 212, respectively, so as to efficiently knead and wash the medicinal materials.

[0050] The other parts of this embodiment are the same as those of the above-mentioned embodiment 1 or 2, and thus will not be described in detail.

[0053] When the planetary flexible roller 22 slides to the limit position along with the slider toward the outer cylinder 212, the planetary gear at the top of the planetary flexible roller 22 meshes with the inner gear ring at the top of the outer cylinder 212 and performs planetary rotation along the inner gear ring. When the planetary flexible roller 22 slides to the limit position along with the slider toward the inner cylinder 211, the planetary gear at the top of the planetary flexible roller 22 meshes with the outer gear ring at the top of the inner cylinder 211 and performs planetary rotation along the outer gear ring.

The magnetic field generated by the magnetic generator 35 drives the magnetic stirring rotor 34 inside the fine washing cylinder 31 to rotate, thereby stirring the medicinal materials inside the fine washing cylinder 31 to improve the fine washing effect of the medicinal materials.

[0057] Furthermore, the rotation speed of the magnetic stirring rotor 34 is less than or equal to 600 rad / min, so as to avoid damage to the surface of the medicinal material due to excessive rotation speed. At the same time, the magnetic stirring rotor 34 is used to replace the traditional stirring roller to stir the medicinal material, thereby eliminating the setting of redundant large-volume rigid structures such as stirring shafts and stirring blades, thereby preventing the medicinal material from being hit by the large-volume rigid structure, and further preventing the medicinal material from being damaged.

[0058] The other parts of this embodiment are the same as any one of the above embodiments 1-4, so they are not repeated here.

[0061] The electromagnetic adsorption component 43 includes a plurality of electromagnetic adsorption plates arranged at intervals, and a water flow channel is provided between adjacent electromagnetic adsorption plates. The water flow channel will not hinder the smooth flow of water.
