Description

Technical Field

[0001] The present invention belongs to the technical field of traditional Chinese medicine processing and relates to a continuous cleaning device for soil-bearing traditional Chinese medicine materials. Background Art

[0002] The cleaning of soil-bearing traditional Chinese medicine materials such as root tubers and underground rhizomes is an important step in the primary processing of traditional Chinese medicine materials. Since the tissues are taken from the soil, the surface cleaning is rather cumbersome. Especially for Polygonatum sibiricum, it is a typical underground rhizome traditional Chinese medicine that is difficult to clean. It has a multi-enlarged node string-like state, and nodules, root hairs, longitudinal wrinkles, sugar residues, etc. form complex soil-hidden gaps on the surface. The cleaning cycle is long, the water consumption is large, and the efficiency is low. Most of them need to be repeatedly soaked and rinsed. Even in order to improve the cleanliness and cleaning efficiency, there is also a method of breaking the node blocks first and then cleaning. Summary of the Invention

[0003] The purpose of the present invention is to provide a continuous cleaning device for soil-bearing traditional Chinese medicine materials in view of the above problems existing in the prior art. The technical problem to be solved by the present invention is how to achieve continuous cleaning and reduce water consumption.

[0004] The purpose of the present invention can be achieved by the following technical solutions: A continuous cleaning device for soil-bearing traditional Chinese medicine materials, characterized in that it includes a water tank, a feeding pipe and a cleaning roller. The feeding pipe is horizontally placed at the opening of the water tank in a way that blocks the opening of the water tank. A number of leakage grooves perpendicular to the axis of the cleaning roller are opened at the bottom of the feeding pipe. A number of stirring blades parallel to the axis of the cleaning roller are arranged on the cleaning roller. A number of brush strips that can partially pass through the leakage grooves are arranged at the outer ends of the stirring blades. One end of the feeding pipe has a feeding hopper, and the other end of the feeding pipe has a discharge port located outside the water tank. The axis of the feeding pipe forms an angle of 3-10° with the horizontal plane, and the feeding end of the feeding pipe is higher than the discharge end; the liquid level of the water in the water tank is lower than the discharge port.

[0005] Further, a number of partition plates are arranged in the water tank along the length direction of the water tank, and a closed cleaning area is formed between adjacent partition plates.

[0006] Further, a partition net is arranged in the middle and lower part of the water tank in each cleaning area. The partition net forms an angle of 10-30° with the horizontal plane. The lower side of the partition net is fixed to one side wall of the water tank, and a slag inlet gap is formed between the higher side of the partition net and the other side wall of the water tank. Water inlet pipes corresponding to each cleaning area are arranged on the feeding pipe, and each cleaning area has a sewage discharge pipe arranged below the lower side of the partition net close to the water tank.

[0007] This solution uses the method of stirring the water with a stirring blade to enable the water to enter the material feeding pipe in a small amount through the leakage trough. At the same time, the brush strip is used to enter the material feeding pipe through the leakage trough to wash the Chinese medicinal materials to be washed in the material feeding pipe. Since the material feeding pipe has a slope, the Chinese medicinal materials to be washed can slowly move from the feeding end direction to the discharging end.

[0008] The reason for the high cleaning efficiency is that the rotation of the brush strip can, on the one hand, drive the material to turn circumferentially in the material feeding pipe and return to the low point of the material feeding pipe under its own weight. In this way, the washing position of the brush strip on the Chinese medicinal materials is constantly switched, and during the movement along the material feeding pipe, the Chinese medicinal materials to be washed can be washed multiple times. In addition, during the process of stirring the water, the water can wash the leakage trough in the reverse direction, avoiding the blockage of the leakage trough, and to a certain extent, the Chinese medicinal materials to be washed are washed by the water flow. This process also realizes the downward discharge of mud and slag, and the water in the water inlet pipe washes the medicinal materials along the way from top to bottom.

[0009] In order to achieve a better water-saving effect and reduce the water inflow of the circulating water, this solution divides the water tank into multiple partitioned areas. Along the material feeding direction, the water replacement amount can be gradually reduced, and substances such as sludge and debris are gathered near the low point of the partition net due to the existence of the partition net, and thus are more easily removed, ensuring the cleanliness of the water above the partition net in the water tank to the greatest extent.

[0010] The cleaning roller is driven to rotate by an external power, and its rotation speed can be adjusted according to needs, but excessive stirring should be avoided to cause more water to flow out at the discharging port. The brush strip is a soft plastic strip, distributed in bundles, and there are gaps between adjacent bundles, ensuring the washing efficiency and allowing the movement of the material.

[0015] The following are the specific embodiments of the present invention and in combination with the drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0016] Such as Figure 1 、 Figure 2 andFigure 3 The traditional Chinese medicine cleaning device shown in the figure includes a water tank 1, a feeding pipe 2 and a cleaning roller 3. The feeding pipe 2 is horizontally placed at the opening of the water tank 1 in a way that blocks the opening of the water tank 1. A number of leakage grooves 4 perpendicular to the axis of the cleaning roller 3 are opened at the bottom of the feeding pipe 2. A number of stirring blades 5 parallel to the axis of the cleaning roller 3 are arranged on the cleaning roller 3. A number of brush strips 6 that can partially pass through the leakage grooves 4 are arranged at the outer ends of the stirring blades 5. One end of the feeding pipe 2 has a feeding hopper 21, and the other end of the feeding pipe 2 has a discharge port 22 located outside the water tank 1. The axis of the feeding pipe 2 forms an angle of 3-10° with the horizontal plane, and the feeding end of the feeding pipe 2 is higher than the discharge end; the liquid level of the water in the water tank 1 is lower than the discharge port 22.

[0017] A number of partition plates 11 are arranged in the water tank 1 along the length direction of the water tank 1, and a closed cleaning area is formed between adjacent partition plates 11. A partition net 12 is arranged in the middle and lower part of the water tank 1 in each cleaning area. The partition net 12 forms an angle of 10-30° with the horizontal plane. The lower side of the partition net 12 is fixed on one side wall of the water tank 1, and a slag inlet gap is formed between the higher side of the partition net 12 and the other side wall of the water tank 1. Water inlet pipes 7 corresponding to each cleaning area are arranged on the feeding pipe 2, and each cleaning area has a sewage discharge pipe 8 arranged below the lower side of the partition net 12 on the water tank 1.

[0018] In this solution, by using the way of the stirring blade 5 to stir the water, the water can enter the feeding pipe 2 in a small amount through the leakage groove 4. At the same time, by using the way of the brush strip 6 entering the feeding pipe 2 through the leakage groove 4, the Chinese medicinal materials to be washed in the feeding pipe 2 are washed. Since the feeding pipe 2 has a slope, the Chinese medicinal materials to be washed can slowly move from the feeding end direction to the discharge end.

[0019] The reason for the high cleaning efficiency is that the rotation of the brush strip 6 can, on the one hand, drive the materials to turn circumferentially in the feeding pipe 2 and return to the low point of the feeding pipe 2 under the action of their own weight. In this way, the washing position of the brush strip 6 on the Chinese medicinal materials is continuously switched, and during the movement along the feeding pipe 2, the Chinese medicinal materials to be washed can be washed multiple times. In addition, during the process of stirring the water, the water can backwash the leakage groove 4, avoiding the blockage of the leakage groove 4, and to a certain extent, the Chinese medicinal materials to be washed are washed by the water flow. This process also realizes the discharge of mud and slag, and the water inlet pipe 7 flushes the medicinal materials in the washing path from top to bottom.

[0020] In order to achieve a better water-saving effect and reduce the inflow of circulating water, this solution divides the water tank 1 into multiple partitioned areas. Along the feeding direction, the water replacement amount can be gradually reduced, and substances such as sludge and debris are gathered near the low point of the partition net 12 due to the existence of the partition net 12, and thus are more easily removed, ensuring the cleanliness of the water above the partition net 12 in the water tank 1 to the greatest extent.

[0021] The cleaning roller 3 is driven to rotate by an external power, and its rotation speed can be adjusted as needed, but excessive agitation should be avoided to prevent excessive water discharge at the discharge port 22. The brush strips 6 are made of soft plastic strips and are distributed in bundles with gaps between adjacent bundles, ensuring the washing efficiency and allowing the movement of materials.

Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar means for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
