Embodiment 1:
The utility model comprises: still kettle 1, steam duct 2, condenser 3, water-and-oil separator 5, volatile oil show looks cup 5-6, emptying conduit 5-5, volatile oil collection translator 5-9.Still kettle 1 comprises at the bottom of tank cylinder, upper cover and the cylindrical can.Still kettle 1 is made by all steel, the tank cylinder is cylindrical, inner sleeve has the hanging basket of splendid attire medicinal material, upper cover and tank cylinder are bolted, in order to guarantee the sealing in the still-process, the junction adds silica gel sealing ring and seals, upper cover is sling by electric hoist, can feed intake in still kettle after slinging, and tank cylinder below directly connects at the bottom of the cylindrical can, heating steam enters from tank cylinder side, disperse conduit by the steam that is fixed at the bottom of the tank, make steam disperse uniformly to enter in the still kettle, make by unitary catheter and enter steam in the tank, in still-process, steadily rise uniformly, the medicinal material in the hanging basket is effectively distilled processing.Steam duct imports in the condenser 3 effectively with the steam that produces in the still kettle, and for the ease of cleaning, steam duct 2 is connected by Quick hoop 2-1 with the condenser junction with upper cover, steam duct 2, and the junction seals with silica gel sealing ring.From the steam in the still kettle 1, by becoming the phlegma with volatile oil after condenser 3 condensations, flow in the water-and-oil separator 5, the area of condenser 3 determines according to still kettle 1 volume, it is 4m that general 1 ton still kettle is selected cross section
2Condenser 3 get final product, emptying conduit 5-5 of condenser 3 Increasing exports plays exhaust and safeguard protection effect.Before producing beginning, open No. 4 ball valve, heating steam is with the Bas Discharged in still kettle 1, the condenser 3 in the tank.Water-and-oil separator 5 has two conduits with condenser 3, respectively that 5-2 is connected with 5-5, condensed distillate flows in the water-and-oil separator 5 by phlegma conduit 5-2 by action of gravity, the conduit that enters in the water-and-oil separator 5 is upturned, make carbonated drink obtain effective separation, liquid level in the water-and-oil separator 5 can slowly be risen stably, be conducive to the little volatile oil of density and assemble to liquid level, reach effective oil-water separation.Water-and-oil separator 5 is made by all steel; the tank cylinder is cylindrical; upper cover closely is connected by bolt with the tank cylinder; tank cylinder below directly connects at the bottom of the cylindrical can; except being connected with the lime set inlet pipe; the top is connected with a volatile oil demonstration by screw thread 5-7 and looks cup 5-6; after looking cup 5-6, the volatile oil demonstration is connected with emptying conduit 5-5; emptying conduit 5-5 connects into a system with condenser 3 outlets again; play exhaust and safeguard protection effect; volatile oil shows that the end opening place cover of looking cup 5-6 has a volatile oil collecting duct 5-4 more a little bit smaller than its caliber; volatile oil is collected certain the time; can be convenient to observe to looking cup 5-6 by the top of the water in the water-and-oil separator 5, flow out to volatile oil collection translator 5-9 collection from a little bit smaller 5-4 of caliber again and remove.Volatile oil collecting duct 5-4 directly leads to water-and-oil separator 5 outsides and is connected with volatile oil collection translator 5-9, this kind design is to make volatile oil more concentrate on the volatile oil demonstration to look among the cup 5-6, because the caliber of 5-4 is less than 5-6, volatile oil can flow into volatile oil collecting duct 5-4 effectively, is convenient to be collected in volatile oil and collects among the translator 5-9.In order to guarantee that volatile oil is collected and the sealing problem of transfer process, volatile oil is collected translator 5-9 and is adopted spring-loaded valve to be connected with volatile oil collecting duct 5-4, spring-loaded valve is fixed in volatile oil to be collected on the translator 5-9, spring when volatile oil collection translator 5-9 is connected with volatile oil collecting duct 5-4 in the spring-loaded valve is depressed, volatile oil is collected translator 5-9 and volatile oil collecting duct 5-4 is connected state, open the valve 5-12 on the volatile oil collecting duct 5-4, volatile oil just can successfully flow into volatile oil and collect among the translator 5-9, collect complete after, take off volatile oil and collect translator 5-9, spring in the spring-loaded valve is upspring rapidly and is made whole volatile oil collection translator 5-9 form an independently sealing member, be convenient to the transfer of volatile oil and avoid pollution, when collecting volatile oil, collect the inside and outside pressure balanced of translator 5-9 for assurance volatile oil, the side that volatile oil is collected translator 5-9 also is communicated with a conduit, catheter tip adopts semi-permeable membranes 5-10 sealing, like this can the equalizing reservoir inner and outer air pressure, can effectively isolate the interior liquid of collector is not exposed in the atmospheric environment yet, avoid polluting, more meet the requirement of GMP.Water layer delivery line 6 extends to water-and-oil separator 5 bottoms, utilize the principle of liquid level difference slowly to get rid of unnecessary moisture in the tank, be control water-and-oil separator 5 water level inside, a circulation and 4-3 have been increased on the water layer delivery line 6, two by-pass valve controls of 4-4, the extraction initial stage is opened the valve 4-3 that water layer delivery line 6 connects, 4-4, the water-and-oil separator water level inside is stabilized near the phlegma import, when extracting certain hour, valve-off 4-3, the water-and-oil separator water level inside will be raised the volatile oil demonstration and be looked cup 5-6 place, be convenient to observe the volatile oil proterties and whether meet the correlated quality standard, the volatile oil liquid level is lifted to and looks cup 5-6 place simultaneously, owing to looking the volume of cup 5-6 much smaller than the volume of water-and-oil separator 5, therefore volatile oil is more conducive to concentrate, reduce the wastage simultaneously, just in time the outlet of 5-4 conduit is positioned at and looks cup 5-6, and volatile oil is more concentrated to be more conducive to discharge and to collect.The water of discharging enters still kettle 1 by conduit, also can discharge by the valve 4-5 of design at lowest order simultaneously, realizes uncompensated distillation extraction.
The utility model is by the effective design to volatile oil extraction separator, make in the volatile oil leaching process, oil water separation process is steady, and oily water separation is abundant, get oil fully fully, sealing, loss be little, has certain application prospect in fields such as Chinese medicinal materials volatile oil extractions.
Specific embodiment described herein only is to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has more used the 1-still kettle, 1-1-still kettle end socket, the 1-2-hanging basket, 1-3-still kettle tank body, 1-4-steam scattering rod, the 2-steam duct, the 2-1-Quick hoop, the 2-2-Quick hoop, the 3-condenser, the 3-1-joint flange, the import of 3-2-water of condensation, the 3-3 condensation-water drain, 4-1-the first ball valve, 4-2-the second ball valve, 4-3-the 3rd ball valve, 4-4-the 4th ball valve, 4-5-the 5th ball valve, 4-6-the 6th ball valve, 5-12-the 8th ball valve, the 5-water-and-oil separator, the 5-1-joint flange, 5-2-phlegma conduit, 5-3-water layer delivery line, 5-4-volatile oil collecting duct, the emptying conduit of 5-5-, 5-6-volatile oil shows looks cup, the 5-7-screw thread, the 5-8-spring-loaded valve, 5-9-volatile oil is collected translator, the 5-10-semi-permeable membranes, the 5-11-semi-permeable membranes is compressing tablet fixedly, the terms such as 6-distillate water layer conduit, but do not get rid of the possibility of using other terms.Using these terms only is in order to describe more easily and explain essence of the present utility model; They are construed to any additional restriction all is contrary with the utility model spirit.
