Model utility content
For solving the technical problem of current existing water injection vacuum pump, the utility model by changing cisten mechanism, increase convection current layering facility, increase Circulated water filter and increase that relief valve solves that traditional water sprays that the pollutant emission that vacuum pump set exists is many, low vacuum and centrifugal pump hold flimsy problem, for the industries such as pharmacy, medicine intermediate, fine chemistry industry, agricultural chemicals, alkalization work, fluorine chemical provide the high vacuum unit of separable, corrosion-resistant, the explosion-proof and stable performance of a kind of solvent.
The technological scheme that the utility model is adopted for achieving the above object is: the corrosion-resistant explosion-proof high vacuum water of a kind of separated from solvent type sprays vacuum pump set, it is characterized in that comprising: water tank, water tank baffle, filter screen I, filter screen II, motor mount, anti-explosion motor, safety check I, corrosion resisting centrifugal pump, blowdown valve, suction port goes out ball valve, anti-explosion vacuum pressure table, gas holder, safety check II, water ejector, fixing device I, filler, fixing device II, water ejector trap, overflow system, spill pipe support, solvent recovery mouth, solvent recovery and sewage draining exit, described overflow system is arranged on the position of water tank side close to top, and water tank bottom is provided with solvent recovery sewage draining exit, after the organic solvent extracted out in container is entered water tank by vacuum pump set, mixed solution by the water stratification in casing, density large on water tank upper strata, the lower floor at water tank that density is little, mesosphere is water, by overflow system, the material on water tank upper strata is reclaimed after using a period of time, solution in water tank bottom layering is reclaimed by the solvent recovery sewage draining exit of water tank bottom, the water circulation use in mesosphere, described water tank baffle is by water tank stratified two-part, a part is centrifugal pump water tank inlet, another part is the recovery tank that water ejector sprays, the filter screen of 2 diameter 150mm is installed in dividing plate neutral position, filter screen aperture is 0.2mm, and two water tanks only carry out convection current by filter screen, the water that water ejector ejects, bubble, the solid particle of condensable material matter and receptacle all refluxes at recovery tank, in recovery tank, by filter screen filtration and the most bubble of removal, the liquid entering centrifugal pump water tank inlet will be relatively stable, because the inlet water tank of centrifugal pump is without the solid particle being greater than 0.2mm, centrifugal pump can not suck larger solid particle and damage centrifugal pump, because bubble is mostly floating at recovery tank, by filtering fragmentation, bubble is there will not be in centrifugal pump water tank inlet, reach the object that centrifugal pump can not suck bubble water inlet sparger, to improve the degree of vacuum that water sprays vacuum pump set.
Preferably, the drive motor of described centrifugal pump and vacuum gauge all use explosion-proof configuration, to reach the use standard that vacuum pump set can be used for extracting out inflammable and explosive gas.
Preferably, the impeller of described centrifugal pump and pump chamber gap are greater than 0.5mm.
Preferably, described whole component, according to different service condition, all select engineering plastics or anticorrosion with painting material on liner engineering plastics or metallic material on metal, to guarantee the antiseptic property of this unit.
The utility model has following beneficial effect: the corrosion-resistant explosion-proof high vacuum water of separated from solvent type of the present utility model sprays vacuum pump set, significantly can reduce enterprise pollution discharge, reduces production and operation to the destruction of physical environment.Due to water tank stratified convection current, significantly can reduce the centrifugal pump that bubble enters work, reach the object improving equipment vacuum degree, better meet process requirements.Can extension device working life, reduce device maintenance maintenance cost.
