Description

Vacuum feeding device of subcritical extraction tank
Technical Field
The utility model particularly relates to a vacuum loading attachment of subcritical extraction jar belongs to subcritical extraction technical field.
Background
When the temperature of the solvent substance is higher than the boiling point, the solvent substance exists in a gaseous state, a certain pressure is applied to the solvent substance to compress the solvent substance so as to liquefy the solvent substance, and the physical properties of the similar and compatible solvent substance are utilized in the state, so that the solvent used for extracting the substance is a subcritical extraction solvent, and the extraction process is called a subcritical extraction process. The extraction of lipid substances from biological raw materials by using subcritical solvents is a new process developed in recent 20 years, and is currently applied to the extraction production of water-soluble and fat-soluble components of dozens of plant raw materials such as vegetable oil, pigments, essential oil, medicinal materials and the like. The production steps of subcritical extraction generally comprise the steps of feeding, vacuumizing, adding solvent for extraction, evaporating and concentrating, recovering the solvent and the like. At present, a feeding mode in a subcritical production process usually adopts a packing auger, a scraper or an open manhole to feed materials into a subcritical extraction tank at normal pressure, and equipment investment, labor cost and production cost are increased and working efficiency is lower for equipment in a high-rise or long-distance material conveying.
Disclosure of Invention
Problem to prior art exists, the utility model provides a vacuum loading attachment of subcritical extraction jar utilizes the vacuum pump system among the current extraction system, realizes that the extraction jar utilizes the negative pressure that the vacuum produced to carry out the material loading.
The technical scheme of the utility model is that: a vacuum feeding device of a subcritical extraction tank comprises a vacuum pump, the subcritical extraction tank and a material box; a material inlet is formed in the top of the subcritical extraction tank, the material inlet is hermetically communicated with the material tank through a feeding pipe, and a first valve is arranged on the feeding pipe; the top of the subcritical extraction tank is also provided with an exhaust port, the exhaust port is communicated with the pumping hole of the vacuum pump in a sealing way through a vacuum tube, and the vacuum tube is provided with a second valve.
Further, the open end of the feed pipe is inserted below the surface of the material in the material box.
Furthermore, a stirring device is also arranged in the subcritical extraction tank.
Has the advantages that: the utility model discloses utilize present vacuum pump system among the subcritical extraction system to extraction jar evacuation, utilize the negative pressure that the vacuum produced, with the material through the automatic high-efficient material loading of realization in the extraction jar of inhaling of inlet pipe, can replace traditional material loading mode. This device is through the simple transformation to current system to less investment has realized throwing the reduction by a wide margin of material cost, and has obviously improved work efficiency, and is simple feasible.
Drawings
Fig. 1 is a schematic view of the structure of the present invention.
The labels in the figure are: the device comprises a vacuum pump 1, an extraction opening 11, a vacuum tube 12, a subcritical extraction tank 2, a material inlet 21, a first valve 22, an exhaust opening 23, a second valve 24, a stirring device 25, a material box 3, a material upper surface 31, a material feeding pipe 32 and a material feeding pipe 321.
Detailed Description
The present invention will be described in more detail with reference to the accompanying drawings, wherein the words "first" and "second" are used for distinguishing different components, and are not in a specific order; the black arrows in the figure represent the direction of flow of the material, air flow, etc.
As shown in fig. 1, a vacuum loading apparatus for a subcritical extraction tank sequentially comprises, from left to right: a vacuum pump 1, a subcritical extraction tank 2 and a material tank 3; a material inlet 21 is arranged at the top of the subcritical extraction tank 2, the material inlet 21 is hermetically communicated with the material tank 3 through a feeding pipe 32, the open end 321 of the feeding pipe is inserted below the upper surface 321 of the material in the material tank 3, and a first valve 22 is arranged on the feeding pipe at a position close to the extraction tank to control the opening and closing of the feeding pipe; an exhaust port 23 is further arranged at the top of the subcritical extraction tank 2, the exhaust port 23 is hermetically communicated with the extraction port 11 of the vacuum pump 1 through a vacuum tube 12, and a second valve 24 is arranged on the vacuum tube 12 close to the extraction tank and used for controlling the opening and closing of the vacuum tube; and a stirring device 25 is also arranged in the subcritical extraction tank and can be used for stirring the filled materials so as to ensure that the materials are uniformly distributed.
The vacuum pump adopted by the device can be the original vacuum pump of the subcritical extraction system, so that the investment can be saved, and the field pipeline arrangement can be saved. The working process of the device is as follows: adding enough material into the material box, and submerging the open end of the feeding pipe into the surface of the material; starting a vacuum pump, opening a second valve to vacuumize the extraction tank, opening a first valve after a certain vacuum degree is reached, enabling the materials to automatically flow into the extraction tank along a feeding pipe under the driving of vacuum negative pressure, and starting a stirring device to stir the materials; and after the materials are added to the required amount, closing the second valve, continuously vacuumizing to a certain vacuum degree, closing the second valve, and adding subcritical fluid into the extraction tank to perform extraction process operation.
The device adopts the vacuum pump in the subcritical extraction system to extract air in the subcritical extraction tank according to the characteristic that the subcritical extraction tank can bear negative pressure, so that the air is generated to suck materials, the purpose of feeding materials can be realized without independently increasing feeding equipment, and the device is simple and reliable, runs economically and stably, and is worthy of popularization and use.
