Abstract

The utility model relates to a deflection continuous counterflow extracting machine, comprising a 90-degree turning extracting groove, both ends of which are jointed by vertical angles and connected in series with a 180-degree turning extracting groove. The technique of the deflection of jet can compact and fold the long-groove extracting machine with a total length of 15-25 meters into a size which can be positioned in a 7m x 7m, about 50m<2> factory site with a capacity of 4m. The extracting machine can deal with 10 thousands of traditional Chinese medicine materials, with the continuous rational input of medical materials and solvents. With the driving power of the liquid level difference between the spiral stowing tool in the extracting groove, the liquid and the solid continuously roll forwards in the counterflow direction; and with the heating of the 100-degree low-temperature saturated vapor, the extracting machine carries out the low energy-cost, high efficient, and high quality extraction. Other various interval single-batch extraction cannot be compared with this utility model, in particular that the dregs of the decoction are continuously and separately discharged out of the site, which really makes the environmental quality of the traditional Chinese medicine production conforms to the requirement of the medicine production.

Description

Deflector type Continuous Countercurrent Extraction machine

Technical field

The utility model relates to a kind of deflector type Continuous Countercurrent Extraction machine, belongs to liquid-solid phase counter-current extraction techniques scope, is applicable to and utilizes water or organic solvent that natural animal-plant is carried out continuous countercurrent extraction.

Technical background

At present most important traditional Chinese medicine extraction technology still rests on single jar of extraction state of very backward batch (-type) in the Chinese medicine production process, yield low energy consumption height, and the scum juice hot vapour that flows over overflows during the useless dregs of a decoction of particularly on-the-spot intermittent discharge, has a strong impact on the pharmaceutical production environment.The patent No. 200320122235.Though 5 deflector type Continuous Countercurrent Extraction machines have solved batch (-type) and have extracted the significant problem that exists for single jar, the operation and the Layout Problem of nearly 20 meters elongated slots of straight channel type countercurrent extraction machine have also been solved, but the extraction tank that mediates in the multistage deflector type Continuous Countercurrent Extraction machine, staff has been difficult to contact, this gives dismounting and please bring very big inconvenience in washing trough inside, and establishing extraction tank gradient governor motion has also increased structural complexity.

Summary of the invention

The utility model purpose provides and a kind ofly can make all extraction tanks, all is in the position that can clean and install and remove maintenance easily, and complete machine structure is more reasonable.

Technical solutions of the utility model are: it is by the waste residue conveying worm, the waste residue groove, solvent inlet, 90 ° of turnover extraction tank driving machines, the extraction tank cover plate, 90 ° of turnover extraction tanks, screw feeder, 180 ° of turnover extraction tanks, drive sprocket, 180 ° of turnover extraction tank driving machines, the extraction tank flange, spiral pusher axle support plate, 180 ° of turnover extraction tank dividing plates, the wetting groove of medicinal material, mixer, the medicinal material import, the extracting liquid outlet groove, formations such as extracting liquid outlet and extractor frame, be characterized in: at 180 ° of turnovers of 90 ° of turnover extraction tank two ends series connection extraction tank, reserve for the passage that cleans and mounting or dismounting are maintained between two 180 ° of turnover extraction tanks, between 180 ° of turnover extraction tank screw feeder diaxons, the rear axle ratio front axle is carried and is done a spacing, 90 ° of turnover extraction tanks slightly are inclination, and the spiral of its screw feeder is local to be disconnected to get out of the way the helical axis of 180 ° of turnover extraction tanks; By spiral pusher axle support plate and extract cell wall and the welding of Low Temperature Steam generator cell wall, extraction tank is suspended to be fixed in the Low Temperature Steam generator, and Low Temperature Steam generator bottom establishes≤and 0.2MPa saturated vapor evaporation heating tube, pure water in the heating evaporation groove produces≤100 ℃ of saturated vapors and uses for each extraction tank heating; Screw feeder is established in each extraction tank bottom, medicinal material quantitatively adds the wetting groove of medicinal material continuously, under stirring, agitator makes medicinal material degassing sedimentation, the wetting back of medicinal material enters extraction tank from the wetting groove of medicinal material bottom, the contrary extract of medicinal material advances until the waste residue groove under driving machine and screw feeder promotion, promote by the waste residue conveying worm then and discharge outdoor, solvent then quantitatively joins the waste residue groove continuously, enter the also contrary medicinal material direction of extraction tank by liquid level difference and advance, cross the adjusting weir plate then and discharge through extracting liquid outlet until the adjusting weir plate of extracting liquid outlet groove; Between wetting groove of medicinal material and extracting liquid outlet groove, leave an intersegmental distance, provide the medicinal material sedimentation in the extract to flow to the extracting liquid outlet groove to reduce medicinal material; The extraction tank dividing plate is not established in 180 ° of turning points at 180 ° of turnover extraction tanks, and two extraction tanks bottom connects with the straight plate that tilts.

Medicinal material and extract constantly turn in the groove that is formed by many helical blades and mix reverse advancing, promote diffusion and infiltration between the liquid-solid phase, spiral grooves has and prevents that back-mixing is to keep the concentration difference of liquid-solid phase, thereby produce the counter-flow extraction effect of expectation, it is fast to reach extraction rate, and active ingredient residual in the adding less and dregs of a decoction of solvent is low.Serialization is extracted and to be made dregs of a decoction discharge capacity even, utilizes the conveying worm can airtight discharge to operating room outside continuously, makes that pharmaceutical production is on-the-spot to keep neatly.

A plurality of extraction tanks are horizontal turnover series connection, extraction tank just can shorten screw feeder and its axle significantly, can also reduce the vertical height of extraction tank significantly, do not need tall and big equipment operating platform, very long extraction tank is shortened to 1/4～1/3 of total length, complete machine structure extracts compact greatly than batch (-type), Continuous Countercurrent Extraction efficient height, can save energy consumption near half, the investment of maximization equipment and factory building also can be saved significantly, and the utility model device structure considered to transfer each extraction tank of series connection all can conveniently maintain and clean.
