DETAILED DESCRIPTION

[0037] In order to make the purposes, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application are clearly and completely described below. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0038] As shown in Figure 1 The present application provides a traditional Chinese medicine extraction device, which comprises a fan unit 1, an extraction tank 2, an extraction liquid storage tank 3 and a concentration device 4 connected in sequence;

[0039] A centrifuge 5 is arranged below the extraction tank 2, and the centrifuge 5 is connected with the extraction liquid storage tank 3 and a dreg treatment device 6 respectively;

[0040] The fan unit 1 is also connected with a hopper 11 through a pipeline between the fan unit 1 and the extraction tank 2;

[0041] The extraction tank 2 is also connected with a first steam pipeline 10 and a solvent supply pipeline 20 respectively.

[0042] The centrifuge 5 is arranged below the extraction tank 2, so that when the dregs are discharged, the dregs are directly discharged into the centrifuge 5 by gravity, thereby saving the additional equipment investment in the transfer process.

[0043] When the device of the present application works, the fan unit 1 compresses and speeds up the sucked air, and then blows the high-speed airflow into the extraction tank 2 through the pipeline. At the same time, the prepared traditional Chinese medicine raw materials are added from the hopper 11 and fall into the pipeline, and then are blown into the extraction tank 2 by the high-speed airflow supplied by the fan unit 1. The traditional Chinese medicine raw materials are transported to the extraction tank 2 by pneumatic transportation. After the medicine feeding is completed, the fan unit 1 is closed, and at this time, the extraction tank 2 is connected with the solvent supply pipeline 20, so that the solvent (water or ethanol in the present application) is injected into the extraction tank 2. When the solvent is added to the preset liquid level, the solvent is stopped, and at this time, the first steam pipeline 10 is connected to supply the heating steam to the extraction tank 2, so that the materials in the tank are heated to the preset temperature by the steam. When the temperature of the materials in the extraction tank 2 reaches a certain value, the steam heating is closed, and the extraction is carried out for a period of time.

[0044] After the extraction is completed, the extraction liquid, i.e. the medicine liquid, is discharged to the extraction liquid storage tank 3, and then the medicine liquid in the extraction liquid storage tank 3 is transferred to the concentration device 4 for concentration treatment.

[0045] When the medicinal liquid in the extraction tank 2 is discharged, a small amount of solvent is added through the solvent supply pipeline 20 to flush the dregs 1-2 times. After the flushing is completed, the extraction tank 2 is opened, the dregs are discharged into the centrifuge 5, and the solvent is added through the solvent supply pipeline 20 to flush the extraction tank 2. The flushing water also falls into the centrifuge 5. After the extraction tank 2 is cleaned, the next batch of extraction process can be performed.

[0046] The dregs falling into the centrifuge 5 are centrifuged by the centrifuge 5 to separate the residual medicinal liquid in the dregs. The separated medicinal liquid is transferred into the extraction liquid storage tank 3 for temporary storage. The dehydrated dregs obtained after centrifugation are transferred into the dregs processing device 6 for processing.

[0047] The traditional Chinese medicine extraction device of the present application sets the centrifuge 5 below the extraction tank 2, uses the centrifuge 5 to dehydrate the dregs, and transfers the dehydrated and separated medicinal liquid into the extraction liquid storage tank 3, thereby realizing the recovery of the residual medicinal liquid in the dregs. The device overcomes the drawbacks of the existing extraction method of traditional Chinese medicine, i.e., the high residual amount of medicinal liquid in the dregs, which leads to the loss of medicinal liquid and the pollution of the environment. In addition, the device of the present application also adds the traditional Chinese medicinal materials in the form of pneumatic conveying through the setting of the fan unit 1, which has the characteristics of saving manpower, high automation, and easy control.

After the medicinal material feeding is completed, the fan unit 1 is closed, the feed inlet 201 is closed, at this time, the liquid inlet 202 is connected with the solvent supply pipeline 20, the solvent (water or ethanol in the application) is injected into the extraction tank 2 from the feed inlet 201, when the solvent is filled to the preset liquid level, the solvent is stopped, at this time, the first steam pipeline 10 is connected to supply heating steam to the heat exchange jacket 24, the material in the tank is heated to the preset temperature by steam, when the material temperature in the extraction tank 2 reaches a certain value, the steam heating is closed and the extraction is kept for a period of time.

[0056] In the application, the fastening structure is, for example, a buckle structure, a quick release flange or the like, which is used to fasten the lower head 22 and the tank body 21, and realize the sealing of the lower head 22 to the tank body 21, and a sealing ring can be arranged at the connection between the lower head 22 and the tank body 21 to prevent liquid leakage.

[0059] As shown in Figure 4 Optionally, the dregs treatment device 6 comprises a dregs collecting pool 61, a transmission device 62, a rotary dryer 63 and a boiler 64 which are sequentially connected in series.

[0060] The smoke output end of the boiler 64 is sequentially connected with the rotary dryer 63 and the smoke treatment device 65.

[0061] The dewatered medicinal residue discharged from the centrifuge 5 is transferred into the medicinal residue collecting tank 61 and is transferred to the rotary dryer 63 by the conveying device 62 (for example, a scraper conveyor in the present application) and is contacted with the flue gas output from the boiler 64 in countercurrent, and the medicinal residue is dried by using the waste heat of the flue gas, and the water vapor discharged during the drying of the medicinal residue is discharged from the rotary dryer 63 and is treated in the flue gas treatment device 65, and the medicinal residue dried in the rotary dryer 63 is input into the boiler 64 as fuel for combustion, and the flue gas obtained by combustion is transferred into the rotary dryer 63 for drying medicinal residue, so that the treatment and utilization of medicinal residue are realized.

[0062] As shown in Figure 5 Optionally, the dust collector 66 is arranged between the flue gas output end of the boiler 64 and the rotary dryer 63.

[0063] In the present application, the dust collector 66 can remove dust from the flue gas output from the boiler 64, so as to avoid that the dust amount of the flue gas entering the rotary dryer 63 is too large and affects the use of the rotary dryer 63.

[0064] Optionally, the dust collector 66 is a cyclone dust collector or a bag dust collector or an electrostatic dust collector.

[0065] In the present application, the dust collector described above can achieve good dust removal effect.

[0066] As shown in Figure 6 Optionally, the concentration device 4 comprises an evaporator 41 and a gas-liquid separator 42.

[0067] The evaporator 41 is connected with the extraction liquid storage tank 3 through the first valve 100.

[0068] The liquid output end of the gas-liquid separator 42 is connected with the liquid input end of the evaporator 41 through the circulating pump 421.

[0071] The steam input end of the evaporator 41 is further connected with the second steam pipeline 46.

[0072] In the application, when the extract solution in the extract solution storage tank 3 is concentrated, the first valve 100 and the second valve 200 are closed first, the compressor 44 is opened, and the evaporator 41 and the gas-liquid separator 42 are pumped to a negative pressure. When the negative pressure in the evaporator 41 and the gas-liquid separator 42 reaches a certain value, the first valve 100 is opened to pump the extract solution in the extract solution storage tank 3 to the evaporator 41 and the gas-liquid separator 42 by negative pressure. When the liquid level in the gas-liquid separator 42 reaches a certain height, the first valve 100 is closed, and the circulating pump 421 is opened to supply steam to the evaporator 41 through the second steam pipeline 46 to heat the extract solution in the evaporator 41. When the extract solution is heated to the evaporation temperature, the steam supplied by the second steam pipeline 46 is closed. At this time, the extract solution will boil and evaporate at the evaporation temperature. The evaporated steam (i.e. secondary steam) is compressed and heated by the compressor (the temperature of the secondary steam can be adjusted to the temperature at the saturated steam pressure by cooling), and then supplied to the evaporator 41 to release the latent heat in the steam to heat and evaporate the extract solution. The steam is condensed into condensed water and discharged into the condensed water tank 45 for storage. When the extract solution is concentrated to the preset concentration, the vacuum is broken, and the second valve 200 is opened to transfer the concentrated extract solution to the concentrated solution storage tank 43. During the concentration process, if the heat of the secondary steam is insufficient, the second steam pipeline 46 can be opened to supplement steam to the evaporator 41 to ensure the smooth progress of the concentration process.

[0073] A traditional Chinese medicine extraction device, and the working process is as follows:

[0074] In use, the fan unit 1 will suck the air and compress the air to high speed, and then blow the high speed air through the pipeline to the extraction tank 2. At the same time, the prepared Chinese herbal medicine raw materials are added from the hopper 11 and fall into the pipeline, and then are blown into the extraction tank 2 by the high speed air supplied by the fan unit 1. The Chinese herbal medicine raw materials are transported to the extraction tank 2 by the air force, and since the support net 221 is arranged in the lower head 22, the Chinese herbal medicine raw materials entering the extraction tank 2 will fall on the support net 221, and the excess gas will be discharged from the exhaust port 203 (at this time, the exhaust port 203 is not connected with the condenser 25). In order to avoid that the dust in the Chinese herbal medicine raw materials is taken out, a filtering device can be arranged at the exhaust port 203 to prevent the dust from polluting the environment. After the Chinese herbal medicine raw materials are added, the fan unit 1 is closed, and the feeding port 201 is closed.

When the temperature of the material in the extraction tank 2 reaches a certain value, the steam heating is closed, and the extraction is maintained for a period of time.

[0075] After the extraction is completed, the extraction liquid, i.e. the medicinal liquid, is discharged from the liquid discharge port 204 to the extraction liquid storage tank 3.

The flushing water also falls into the centrifugal machine 5, the extraction tank 2 is cleaned, the lower head 22 is closed, and the next batch of extraction process is performed.

[0077] The dregs falling into the centrifugal machine 5 are centrifuged to separate the residual medicinal liquid in the dregs, the separated medicinal liquid is transferred into the extraction liquid storage tank 3 for temporary storage, and the dehydrated dregs obtained after the centrifugation are transferred into the dregs treatment device 6 for treatment.

[0078] When the dregs are treated, the dewatered dregs discharged from the centrifuge 5 are transferred into the dregs collecting pool 61 and are transferred to the rotary dryer 63 by the conveying device 62 (for example, a scraper conveyor in the present application) to be in countercurrent contact with flue gas output from the boiler 64, and the dregs are dried by using the waste heat of the flue gas, and the water vapor discharged during the drying of the dregs is discharged from the rotary dryer 63 into the flue gas treatment device 65 for treatment, and the dregs dried in the rotary dryer 63 are input into the boiler 64 as fuel for combustion, and the flue gas obtained by combustion is transferred into the rotary dryer 63 after being dedusted by the dust collector 66 for drying the dregs, thereby realizing the treatment and utilization of the dregs.

When the medicinal liquid is heated to the evaporation temperature, the steam supplied by the second steam pipeline 46 is closed, at this time, the medicinal liquid will boil and evaporate at the evaporation temperature, the evaporated steam (i.e. secondary steam) is supplied to the evaporator 41 after being compressed and heated by the compressor, the latent heat in the steam is released to heat the medicinal liquid to boil and evaporate, and the steam is condensed into condensed water and discharged to the condensed water tank 45 for storage. When the medicinal liquid is concentrated to a preset concentration, the vacuum is broken, and the second valve 200 is opened to transfer the concentrated medicinal liquid into the concentrated liquid storage tank 43.
