Description
Technical Field
The utility model particularly relates to a exempt from tripper wind transportation material feeding unit for subcritical extraction belongs to material transport technical field.
Background
The subcritical extraction is a new technology for extracting target components from natural products by taking subcritical fluid or mixed solution of subcritical fluid as solvent and sequentially carrying out leaching, evaporation and desolventizing, compression, condensation and recovery and other processes with solute in a system, and is particularly suitable for extracting volatile oil, grease or fat-soluble components in the natural products. The extraction under the subcritical environment does not damage heat-sensitive components, and the target object is complete, so that the method is regarded as a revolutionary technology with environmental protection and wide prospect. The extraction process is slowest, generally, in order to improve the working efficiency, a plurality of extraction tanks are generally operated in parallel in industrial subcritical extraction plants, and in the operation mode of extraction, a set of discharger and air lock are required to be installed on each extraction tank and connected with a material box through a pipeline. This kind of arrangement needs many trippers, and equipment input cost is high, and the job site energy consumption is high, the overall arrangement is complicated, the fault rate is high, and the long distance transport of material of being not convenient for.
Disclosure of Invention
Problem to prior art existence, the utility model provides a exempt from tripper wind transport material feeding unit for subcritical extraction has saved the tripper on each extraction jar and has closed the wind ware, and the remote of the material of being convenient for is thrown the material and is transported.
The technical scheme of the utility model is that: an unloader-free pneumatic conveying and feeding device for subcritical extraction comprises a material box, a fan, a closed air feeder, an extraction tank and a dust remover; the air-blocking feeder is respectively communicated with the material box and the fan; a material inlet is formed in the top of the extraction tank, the material inlet is connected with the air-closed feeder through an air pipe, and a first valve is arranged on the air pipe; the top of the extraction tank is provided with an air outlet, the air outlet is connected with the dust remover through a pipeline, and a second valve is arranged on the pipeline.
Further, the fan is a roots fan.
Further, the dust remover is a bag type dust remover.
Furthermore, a stirring device is also arranged in the extraction tank.
Has the advantages that: the utility model combines the Roots blower and the air-closed feeder, so that the material is directly sent into the extraction tank through the pipeline, and the material is deposited due to the rapid reduction of the flow velocity after entering the extraction tank because the extraction tank has a certain volume, and the air carrying dust can be directly emptied after being filtered by the bag-type dust collector; the utility model discloses can save the tripper of installation on the conventional jar and close the wind ware to can realize the remote material of throwing of single or many extraction jars through the control to the valve switch and carry, simple structure, economy is feasible.
Drawings
Fig. 1 is a schematic view of the structure of the present invention.
The labels in the figure are: 1 roots's fan, 2 shut the air feeder, 3 material cases, 4 tuber pipes, 5 extraction jars, 51 material entry, 52 first valve, 53 air outlets, 54 second valves, 55 agitating unit, 6 sack cleaner.
Detailed Description
The invention will be described in more detail below with reference to the accompanying drawings, without limiting the scope of protection of the patent, in which arrows indicate the direction of flow of the material or fluid.
As shown in fig. 1, a discharger-free pneumatic conveying and feeding device for subcritical extraction comprises a material tank 3, a roots blower 1, a wind-closed feeder 2, an extraction tank 5 and a bag-type dust remover 6; the extraction tank 5 is also internally provided with a stirring device 55; the material box is communicated with a feeding port of the air-tight feeder, and an air inlet of the air-tight feeder is communicated with the Roots blower; the discharge hole of the air-blocking feeder is communicated with a material inlet 52 arranged at the top of the extraction tank 5 through an air pipe 4, and the air pipe is provided with a first valve 52; the top of the extraction tank is also provided with an air outlet 53, the air outlet 53 is connected with the bag-type dust collector 6 through a pipeline, and a second valve 54 is arranged on the pipeline.
The work flow of the wind conveying and feeding device is as follows: the material that waits to deliver is added in the material storage tank, open first valve this moment, open the second valve, start the roots's fan, the material sends the material into the extraction jar along the tuber pipe from closing wind feeder bottom under roots's fan's blowing this moment, because extraction jar itself has certain volume, the material gets into after the extraction jar because the velocity of flow sharply reduces and the deposit gets off, start the agitating unit of extraction jar simultaneously and make the material evenly descend, dust wherein is carried by wind-force and enters into the sack filter from the air outlet and carries out high efficiency filtration, the air can directly be emptied after the sack dust remover filters, accept the pocket below the dust remover and be used for regularly collecting the dust. When the material quantity in the extraction tank meets the requirement, the Roots blower is stopped, the first valve and the second valve are closed, and after the feeding is finished, the extraction solvent can be added into the extraction tank to perform subcritical extraction.
The flow is directed at the reinforced technology of single extraction jar, and this device still can be applied to the operating mode of many extraction jars concurrent work simultaneously, when many extraction jars during operation, can share one set of roots's fan with close air feeder and sack cleaner, many extraction jars all communicate with it through pipeline and valve, can realize throwing the material to many extraction jars through the control to the valve. The pneumatic conveying device is particularly suitable for long-distance delivery and conveying of materials.
Finally, it should be noted that although the present patent is mainly applied to the feeding link of the extraction tank in the subcritical low-temperature extraction process, the design idea of the present patent can be adopted for the conventional extraction and the similar feeding steps, and the implementation and application thereof are all covered in the protection scope of the present patent.
