Description

Technical Field

[0001] This application relates to the technical field of traditional Chinese medicine sorting machines, and particularly to a method for sorting and cleaning traditional Chinese medicine. Background Art

[0002] Traditional Chinese medicinal materials emphasize genuine regional drugs, and the size and age of the medicinal materials will affect the medicinal properties of traditional Chinese medicine. In the actual production process, it is necessary to sort the medicinal materials according to their size to ensure the stable and reliable medicinal properties of traditional Chinese medicine products. Before sorting traditional Chinese medicinal materials, it is also necessary to clean the traditional Chinese medicinal materials to obtain relatively clean medicinal materials, which is convenient for sorting. If the traditional Chinese medicine is sorted first and then cleaned, the reliability of the sorting result will be affected. Therefore, there must be a cleaning step before sorting traditional Chinese medicinal materials. During the cleaning process of traditional Chinese medicinal materials, a lot of sludge or waste materials generated by the fragmentation of medicinal materials are not easy to clean, and waste materials are also easily generated during the sorting process, which affects the sorting efficiency and quality. The existing sorting equipment is not easy to clean.

[0003] In the Chinese patent literature, the utility model patent with the patent number CN2020205452307 was authorized and announced on December 15, 2020. This application case discloses an automatic sorting device for traditional Chinese medicine decoction pieces, including a sorting tank; a feeding funnel is arranged in the upper inner cavity of the sorting tank; the bottom of the feeding funnel is communicated with a feeding channel coaxially arranged with the inner cavity of the sorting tank, and a rotating shaft is coaxially arranged in the upper inner cavity of the sorting tank; a screening net is also fixedly arranged in the sorting tank, and the inner cavity of the sorting tank between the feeding funnel and the screening net is a separation cavity, and at least four groups of material pushing rods are arranged on the rotating shaft extending into the separation cavity. Its disadvantages are as follows: The sorting device is of a tank structure, and the screening net is not easy to take out, and it is also impossible to clean when the waste residue blocks the screening net. In addition, its sorting function depends on the screening net to complete, and the waste materials of traditional Chinese medicine decoction pieces are screened out through the screening net.

[0004] There is a lack of an integrated machine for cleaning and sorting traditional Chinese medicine raw materials in the prior art. Summary of the Invention

[0005] Based on the above deficiencies in the prior art, the present invention provides a method for sorting and cleaning traditional Chinese medicine, in which sorting and cleaning are carried out simultaneously, and the sorting efficiency is high; the working efficiency of the screening belt plate is high, and it does not need to be frequently disassembled and washed, and the cleaning and replacement are also very simple.

[0006] In order to achieve the above invention purpose, the present invention adopts the following technical solutions.

[0007] A method for sorting and cleaning traditional Chinese medicines, characterized in that it is completed by an integrated machine for sorting and cleaning traditional Chinese medicines; the integrated machine for sorting and cleaning traditional Chinese medicines includes a feeding belt and a cleaning tank. One end of the cleaning tank is provided with a water inlet hole. The cleaning tank includes a large material tank and a small material tank, and an air blowing pipe is arranged in the cleaning tank; a large material discharging belt is arranged in the large material tank; a feeding belt inclined downward is arranged on the lower side of the feeding belt, and a screening belt plate located in the small material tank is arranged at the end of the feeding belt; screening holes are arranged in the screening belt plate, and a small material discharging belt is arranged in the small material tank; both ends of the screening belt plate are rotatably connected to the two side walls of the small material tank; the middle of the screening belt plate protrudes downward, and a jacking mechanism is arranged on the lower side of the screening belt plate. One end of the cleaning tank away from the water inlet hole is connected to a filter chamber through a pipeline; the process of sorting and cleaning is as follows: the transportation of traditional Chinese medicines is completed through the feeding belt. The large-volume traditional Chinese medicines are intercepted by the screening belt plate, and the small-volume medicines fall into the small material tank. The large-volume medicines fall into the large material tank by the jacking mechanism pushing the screening belt plate. The jacking mechanism shakes the screening belt plate to make the small-volume traditional Chinese medicines fall into the cleaning tank for cleaning.

With the upward pushing effect of the air bubbles of the air blowing pipe, the convection cleaning of the medicines by the water body is realized. Finally, the cleaned medicines are transported upward out of the cleaning tank through the discharging belt. After being sprayed and rinsed by the spraying device, they fall from the rear end of the discharging belt onto the horizontally arranged conveyor belt and are sent out. The sewage in the cleaning tank flows to the filter chamber for filtering. The sludge accumulates on the left side of the filter screen and is directly discharged from the sludge discharge port.
