System S3 continues to heat solvent, so that solvent maintains the preset temperature of traditional Chinese medicine extraction.
After a period of time, when medicament reaches the concentration of setting, two-way valve valve 121, the medicament in extractor 21 are opened
It is shifted into extractor 22, the solvent in surge tank 1 is continuously added to extractor 21.At the same time, heating extraction system E1, plus
Thermal extraction system E2 is opened, and heating extraction system E3 is closed, and buffer system S1 and buffer system S2 are closed, and buffer system S3 is opened
It opens, new solvent is added in surge tank 1 and by buffer system S3 circulating-heating.
After extractor 21 and extractor 22 extract a period of time, two-way valve 122 is opened, the medicament in extractor 22 is to extraction
Tank 23 shifts, and the medicament in extractor 21 is shifted to extractor 22, and extractor 21 is added in solvent in surge tank 1, at this point, heating mentions
It takes system E1, E2, E3 while opening, extractor 21,22,23 extracts operation simultaneously, and new solvent is added in surge tank 1 simultaneously
Heating waits.
After a period of time, finished product medicament, after 21 medicament of extractor is transferred to extractor 23, extractor 21 is discharged in extractor 23
Drug row slag and during being packed into new drug, medicament of the solvent in buffer system S1 circulating-heating, extractor 22 turns in surge tank 1
Extractor 21 is moved to, the second extractor 22 is added in the solvent in surge tank 1.After new solvent is added in second extractor 22, second is mentioned
Tank headed by tank 22 is taken, the first extractor 21 is tail tank.
Similarly, after new solvent is added in third extractor 23, tank headed by third extractor 23, the second extractor 22 is tail
Tank.After new solvent is added in first extractor 21, tank headed by the first extractor 21, extractor is 23 tail tanks, is so repeated not
Interruption is continuous to be extracted.
Pot group type dynamic countercurrent provided in this embodiment extracts energy conserving system, absorbs the low product in environment using heat pump system
Position air can heat solvent and medicament, instead of traditional steam-heated mode, using the side of medicament direct contact heat transfer
Formula greatly improves the utilization rate of heat exchange efficiency and energy, while energy saving；The system is recycled using multiple extractors simultaneously
The mode used makes each extractor Chinese medicine and the dregs of a decoction maintain reasonable concentration difference, improves recovery rate；It is mentioned by heating
The switching of system and buffer system is taken, the dynamic equipment such as compressor and circulating pump is constantly in operating status, avoids frequent starting
The damage of dynamic equipment is caused, and realizes making full use of for energy.
On the basis of the above embodiments, heat pump system described in the present embodiment further include: evaporator 14 and compressor
3, condenser 81,82,83 parallel with one another and shared one group of evaporator 14 and compressor 3 by heat pump cycle pipeline.
Wherein, equally pass through circulating line successively between the condenser 81,82,83 of evaporator 14, compressor 3 and parallel connection
The heat pump circulating system of closed loop is connected and formed, is respectively corresponded on the heat pump cycle pipeline where the parallel branch of each condenser
It is provided with throttle valve 91,92,93.
In this way, changing for each condenser of real-time control series connection with it can be carried out by the aperture of each throttle valve of control
The thermal efficiency is further realized to the temperature of solvent in surge tank and is each mentioned will pass through buffer system and heating extraction system
The temperature of medicament in tank is taken to carry out real-time control, specifically, 3 throttle valve openings are consistent in the startup stage of traditional Chinese medicine extraction；
When extracting medicament successively relay transfer between different extractors, there are buffer systems and heating extraction system to carry out parallel
The case where work, the aperture for being now in the throttle valve on heating extraction system circuit are much smaller than and are on buffer system circuit
The aperture of throttle valve, and as the temperature of solvent in surge tank increases, the aperture of throttle valve is gradually on buffer system circuit
Reduce；Finally when each extractor carries out traditional Chinese medicine extraction operation simultaneously, three throttle valve openings reach unanimity.
Known, condenser includes shell and is located at the intracorporal heat exchanger tube of shell, and what is circulated in heat exchanger tube is working medium (system
Cryogen), the heat exchanger channels of interlayer space between shell and heat exchanger tube alternatively fluid.For the present embodiment,
When buffer system S1, S2 and S3 initiating task, the fluid for flowing through heat exchanger channels is solvent, and solvent is specially water；When heating mentions
When system E1, E2 and E3 being taken to start work, the fluid for flowing through heat exchanger channels is medicament.
For heat pump system when carrying out cycle operation, it is low-grade that working medium (refrigerant) absorbs external environment in evaporator 14
Air energy improves its temperature and enthalpy by compressor 3, then flows through the heat exchanger tube in condenser, and release is latent within the condenser
Heat, and the solvent or medicament in heat exchanger channels absorb the latent heat discharged by heat exchanger tube by heat exchange；After discharging latent heat
Working medium is corresponding to reenter evaporator 14 after throttle valve decrease temperature and pressure, then absorbs the low-grade sky in environment by evaporator 14
Gas energy, to complete a circulation.
Thus, heating system described in the present embodiment takes full advantage of the low-grade air energy in environment, and will be low-grade
Air can be converted into thermal energy, realize the supply in extraction of traditional Chinese medicine to solvent and medicament institute calorific requirement.
Further, as the improvement of above-described embodiment, by the way that traditional condenser is replaced into three Jie in the present embodiment
Matter condenser, while increasing the steam circulation heating circuit heated using the steam that the medicament in extractor generates.
Wherein, three medium condensers specifically include two heating working medium channels and a heat exchanger channels, two heating working mediums
Channel is respectively refrigerant flow path and medicament steam flow channel, and a heat exchanger channels are to extract heat exchange runner, extracts heat exchange runner and is
For the heat exchanger channels of condenser described in foregoing embodiments, each extractor 21,22,23 passes through jet chimney and medicament respectively
The both ends of steam flow channel are connected, wherein vapour compression machine 71,72,73 is correspondingly arranged on one section of steam circulation pipeline, thus
Form complete steam circulation heating circuit.It should be noted that vapour compression machine is generally located on for steam in extractor
On the steam circulation pipeline of outflow.
Specifically, the both ends of extractor 21,22,23 pass through respectively first pipe 211,212,213 and condenser 81,82,
The 83 corresponding both ends for extracting heat exchange runner are connected.In addition, refrigerant flow path is for the refrigerant circulation in heat pump system, system
The both ends of refrigerant flow conduit for realizing the heat pump cycle pipeline of each condenser parallel connection respectively by being connected.
On the basis of the above embodiments, the top on the inside of extractor is equipped at least one set of spray head, extractor 21,
22,23 corresponding spray head 131,132,133, wherein each spray head is settable 2~3 groups specific, and setting spray head is mainly used for really
It protects remaining medicament in hydronic medicament and extractor and carries out fully contact heat-exchanging, to further increase mentioning for Chinese medicine
Take efficiency.Wherein, it drenches on head and is provided with spray apertures, the diameter of spray apertures is 3mm~5mm.
