Problems solved by technology
Among them, due to the high viscosity and many particles of the traditional Chinese medicine extract, the filter in the extraction tank and the double filter are prone to clogging, which not only leads to incomplete extraction, but also causes leakage due to excessive local pressure, causing serious damage to equipment, pipelines, etc.

Embodiment Construction
[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.
[0032] It should be understood that terms such as "having", "comprising" and "including" as used herein do not entail the presence or addition of one or more other elements or combinations thereof.
[0033] figure 1 An implementation form according to the present invention is shown, which includes: an extraction tank 1, a duplex filter 2 and a pump 3 for returning the feed liquid to the extraction tank are sequentially arranged on the pipeline for extracting liquid circulation, wherein the duplex The filter can be switched to work with a single machine, or it can work with two machines at the same time to expand the filtration flow rate. It is not necessary to stop the extraction work while cleaning and replacing the filter, so as to ensure the continuous operation of the pro...

The invention discloses a device for judging and dealing with solution discharge blockage in the traditional Chinese medicine extracting process. According to the device, an extracting tank, a duplex filter and a pump making feed liquor return to the extracting tank are arranged on an extracting solution circulating pipeline in sequence, a valve and a tuning fork level meter are arranged between the extracting tank and the duplex filter in sequence, and a solution discharge flowmeter is arranged between the duplex filter and the pump; a filter screen is arranged at the bottom of the extracting tank, and the bottom of the extracting tank is further connected with a compressed air reverse blowing system through a back flushing valve; an extracting solution storage tank is further connected between the pump and the extracting tank through a switching valve. The invention further discloses a control method for judging and dealing with solution discharge blockage in the traditional Chinese medicine extracting process through the device for judging and dealing with solution discharge blockage. By means of the method, blockage can be effectively judged and dealt with, forced extracting solution circulation and stable solution discharge in the traditional Chinese medicine extracting process can be maintained, and damage to the equipment and the pipeline can be avoided.
Description
technical field [0001] The invention relates to the field of traditional Chinese medicine pharmacy. More specifically, the present invention relates to a device and control method for judging and preventing blockage in the process of extraction of traditional Chinese medicine. Background technique [0002] Extraction of traditional Chinese medicine is the process of dissolving the active ingredients in traditional Chinese medicine from plant tissues with an appropriate solvent. During the extraction process of traditional Chinese medicine, the Chinese medicine extract flows through the filter in the extraction tank, then passes through the double filter, and finally returns to the extraction tank to form a forced circulation; after the extraction of Chinese medicine, the Chinese medicine extract flows through the filter in the extraction tank. After being filtered with a net, it is filtered through a double filter, and finally reaches the extraction liquid storage tank. Am...
