Summary of the invention
In order to address the above problem, the utility model provides a kind of oily-water seperating equipment, and this device adopts vacuum membrane type separate mode, sewage by vacuum inhalation device body after, by gravity separation, pass through adsorption filtration and membrane sepn more respectively, finally discharge water quality and can reach tap water quality.
The present invention has adopted following technical scheme: a kind of oily-water seperating equipment, it comprises strainer, the one-level water-and-oil separator, spiral pump, oil content concentration alarm record instrument, magnetic valve, strainer is connected with the inside of one-level water-and-oil separator, the one-level water-and-oil separator comprises the gathering room at top and the coalescer of bottom, bottom at the one-level water-and-oil separator communicates with the screw rod pump intake, be provided with T-valve in the spiral pump exit, first valve port of T-valve is connected with the spiral pump outlet, the spiral pump outlet is passed through second valve port and is connected at oil content concentration alarm record instrument, it is characterized in that: further comprising secondary filter, the screw rod pump outlet is connected with the import of secondary filter by the 3rd valve port, be connected with secondary oil in water emulsion separator on the secondary filter, the lower inlet of oil in water emulsion separator and the outlet of secondary filter are joined, and the outlet on the top of oil in water emulsion separator is connected with oil content concentration alarm record instrument.
Be provided with the high precision fiber filter core in the described secondary filter, fabric filter element is connected with secondary filter by screw thread, also is provided with electric contact pressure in secondary filter.The top that described secondary oil in water emulsion separator is provided with is provided with the micro-filtration element, is provided with some distribution openings and oil in water emulsion separative element successively in the bottom.The top of described one-level water-and-oil separator is provided with the oil level detection device, is connected with magnetic valve on the oil level detection device.
The beneficial effects of the utility model are: the present invention adopts vacuum membrane type separate mode, after sewage is sucked primary separator by spiral pump by vacuum, pass through gravity separation, if it is defective, enter again in second-stage separator and the secondary filter through adsorption filtration and membrane sepn, final discharging water quality can reach tap water quality, so not only handle the lighter sewage of emulsification (one-level is handled qualified sewage and no longer changed second-stage treatment over to) effectively automatically, and can discern and effectively handle the serious sewage of emulsification automatically, can save the water source effectively, the present invention is provided with oil content concentration alarm record instrument, enter during the secondary separating process directly changes by oil content concentration alarm record instrument by flash trapping stage, easy to use.Highly sensitive.

Embodiment
In Fig. 1, the present invention is a kind of oily-water seperating equipment, it comprises strainer 1, one-level water-and-oil separator 2, spiral pump 3, oil content concentration alarm record instrument 5, magnetic valve, strainer 1 is connected with the inside of one-level water-and-oil separator 2, one-level water-and-oil separator 2 comprises the gathering room at top and the coalescer of bottom, the top of one-level water-and-oil separator (2) is provided with the oil level detection device, be connected with magnetic valve on the oil level detection device, bottom at one-level water-and-oil separator 2 communicates with the suction port of spiral pump 3, be provided with T-valve 7 in spiral pump 3 exits, first valve port of T-valve 7 is connected with spiral pump 3 outlets, spiral pump 3 outlets are passed through second valve port and are connected at oil content concentration alarm record instrument 5, it also comprises secondary filter 4, be provided with the high precision fiber filter core in the secondary filter 4, fabric filter element is connected with secondary filter 4 by screw thread, in secondary filter 4, also be provided with electric contact pressure, the outlet of spiral pump 3 is connected by the import of the 3rd valve port with secondary filter 4, be connected with secondary oil in water emulsion separator 6 on the secondary filter 4, the top that secondary oil in water emulsion separator 6 is provided with is provided with the micro-filtration element, be provided with some distribution openings and oil in water emulsion separative element successively in the bottom, the lower inlet of secondary oil in water emulsion separator 6 and the outlet of secondary filter 4 are joined, and the outlet on the top of oil in water emulsion separator is connected with oil content concentration alarm record instrument 5.Primary separator is made up of top gathering room and bottom coalescer.Bottom connecting screw rod pump inlet.
According to Fig. 2, work of the present invention is as follows: in the drainage procedure of spiral pump 3 after the relief outlet place of one-level water-and-oil separator 2 suction process, make and produce vacuum in the one-level water-and-oil separator 2, limber water enters one-level water-and-oil separator 2 internal divergence spouts through coarse filter 1 and top suction/draining valve, carry out gravity separation, larger oil droplet is floating to the top gathering room, the sewage that contains the small-particle oil droplet enters special coalescer downwards, carry out coarse separation in inside, form than larger oil droplet and continue come-up to the top gathering room.Sewage after the separation is discharged by spiral pump 3 through the separator bottom, qualified discharge water row outboard.When discharge water was not up to standard, oil content concentration alarm record instrument 5 sent signal, and 7 actions of crossover tee valve make first grade discharging water enter secondary oil in water emulsion separator and proceed the micro-filtration separating treatment.The oily water that contains superfine small oil droplet and small suspended solid is after secondary filter filters, enter secondary oil in water emulsion separator 6 bottoms, by importing after several distribution openings in the oil in water emulsion separative element, after sump oil is stopped by the element micropore, blowdown variable valve by secondary oil in water emulsion separator 6 tops with partial reflux sewage reboard at the bottom of, most of sewage is accumulated clean water up to standard by millipore filtration and discharges outboard.When secondary oil in water emulsion separator handling property lost efficacy, secondary discharges when defective, and oil content concentration alarm record instrument 5 sends signal once more, and the reboard magnetic valve is opened, at the bottom of the treating water reboard.Sump oil after the separation gathers to a certain degree at the top of one-level water-and-oil separator 2, and the oil level detection device sends signal, enters separator by the solenoid control clear water and carries out back flushing, and the sump oil that is collected at the top is arranged automatically to wiper tank.
