Abstract
The invention discloses an IPA supply and recovery device. The IPA supply and recovery device comprises an IPA supply device and an IPA recovery device. The IPA supply device comprises an IPA storage barrel (1), a supply pump (2), a transfer tank A (3), a pneumatic diaphragm pump A (4) and a filter (5), wherein the IPA storage barrel (1), the supply pump (2), the transfer tank A (3), the pneumatic diaphragm pump A (4) and the filter (5) are sequentially connected. The liquid outlet end of the pneumatic diaphragm pump A (4) reaches an equipment use point (6) through a pipeline. The IPA recovery device comprises a transfer tank B (7), a pneumatic diaphragm pump B (8) and a waste IPA storage barrel (9), wherein the transfer tank B (7), the pneumatic diaphragm pump B (8) and the waste IPA storage barrel (9) are sequentially connected through pipelines. The liquid inlet end of the transfer tank B (8) is communicated with the waste IPA storage tank on the equipment use point (6) through a pipeline. The IPA supply and recovery device has the advantages that the structure is simple, the risks that IPA steam and air form an explosive mixture are reduced, and IPA use safety is improved.
Description
Technical field
The present invention relates to IPA, particularly a kind of IPA supply and recovering device.
Background technique
IPA is water white transparency volatile liquid.Low boiling, have the smell like ethanol and acetone mixture, its smell is little.Its steam-energy produces minimal irritation to eyes, nose and throat; Be absorbed by the body by skin.Dissolubility: water-soluble, most organic solvent such as alcohol, ether, benzene, chloroform.Can be miscible with water, alcohol, ether.Azeotropic mixture can be formed with water.Inflammable, steam and air form explosive mixture, explosion limit lower 2.5 vol.% Upper 12.7 vol.%(volume) belong to a kind of medium explosion risk article.Its steam-energy rolls and flows through quite long distance, and can produce tempering trade mark boiling range DEG C ASTM D1078 Mod viscosity, 25 DEG C of cSt ASTM D445 flash-point DEG C ASTM D56 isopropanol 81-832.6112 purposes: important chemical product and raw material.Be mainly used in pharmacy, cosmetics, plastics, spices, coating and electronics industry are used as dehydrating agent and washing agent.Measure the reagent of barium, calcium, magnesium, nickel, potassium, sodium and strontium etc.Chromatographic analysis reference material.Used in electronic industry.In much industry and consumer products, isopropanol is used as low cost solvent, is also used as extractant.
Therefore when using IPA, IPA can not be allowed cruelly to leak the aerial time oversize, therefore when after use IPA, collections sealing preservation will be carried out to IPA immediately.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, provide that a kind of structure is simple, Security good and explosion-proof IPA supplies and recovering device.
Object of the present invention is achieved through the following technical solutions: a kind of IPA supply and recovering device, it comprises IPA feeding mechanism and IPA recovering device, described IPA feeding mechanism comprises IPA storage barrel, supply pump, transfer tank A, membrane pump with pneumatic drive A, described IPA storage barrel is connected with supply pump liquid feeding end pipeline, the outlet end of described supply pump is connected with transfer tank A, the liquid feeding end of described membrane pump with pneumatic drive A is connected with transfer tank A, the outlet end of membrane pump with pneumatic drive A arrives at equipment use point by pipeline, described IPA recovering device comprises the transfer tank B connected successively by pipeline, membrane pump with pneumatic drive B and useless IPA storage barrel, the liquid feeding end of described transfer tank B is communicated with the useless IPA accumulator tank on equipment use point by pipeline.
Pipeline between described membrane pump with pneumatic drive A and equipment use point is provided with a filter.
Described transfer tank A is provided with nitrogen seal device.
Described transfer tank B is provided with nitrogen seal device
The present invention has the following advantages: IPA supply of the present invention and recovering device, transported by pump, ensure that the transport pressure of IPA, be provided with filter, avoid line clogging, improve IPA purity, IPA is preserved by recovering device sealing after using immediately, decreases the time that IPA contacts with air, reduce the risk that IPA steam and air form explosive mixture, improve the Security that IPA uses.
Accompanying drawing explanation

Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described, and protection scope of the present invention is not limited to the following stated:
As shown in Figure 1, a kind of IPA supply and recovering device, it comprises IPA feeding mechanism and IPA recovering device, described IPA feeding mechanism comprises IPA storage barrel 1, supply pump 2, transfer tank A3, membrane pump with pneumatic drive A4, described IPA storage barrel 1 is connected with supply pump 2 liquid feeding end pipeline, the outlet end of described supply pump 2 is connected with transfer tank A3, the liquid feeding end of described membrane pump with pneumatic drive A4 is connected with transfer tank A3, the outlet end of membrane pump with pneumatic drive A4 arrives at equipment use point 6 by pipeline, described IPA recovering device comprises the transfer tank B7 connected successively by pipeline, membrane pump with pneumatic drive B8 and useless IPA storage barrel 9, the liquid feeding end of described transfer tank B8 is communicated with the useless IPA accumulator tank on equipment use point 6 by pipeline, IPA after use, enter in transfer tank B8 by pipeline immediately, avoid IPA liquid to expose for a long time in atmosphere, IPA steam mixes with air and produces explosive mixture, thus bring potential safety hazard.
In the present embodiment, pipeline between described membrane pump with pneumatic drive A4 and equipment use point 6 is provided with a filter 10, IPA liquid filters by filter 10, pipe outlet is avoided to block, filter out the impurity in IPA liquid simultaneously, improve the purity of IPA, reduce IPA and to try to make a good showing the risk mixing with air and blast.
In the present embodiment, transfer tank A3 is provided with nitrogen seal device, transfer tank B8 is provided with nitrogen seal device, avoid transfer tank A3 directly to contact with the IPA liquid-to-air in transfer tank B8, prevent IPA from volatilizing, oxidized.
