Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
Among Fig. 1, comprise liquid-inlet 1, guiding gutter 2, first chamber 3, oil drain out 4, oil spilling groove 5, dividing plate 6, second chamber 7, overflow launder 8, efflux mouthfuls 9, outlet pipe 10, base plate 11, filtering material 12, slag-drip opening 13, seabed pipe 14, liquid level gauge 15, steam heater 16, control valve 17, electric heater unit 18, thermocouple 19, casing 20 etc.
As shown in Figure 1, the utility model is a kind of Treatment of Metal Surface special oil separator, comprises the casing 20 of cuboid, and pack with insulation material around the whole box body 20 and bottom, to keep the temperature in the casing 20.The volume of casing 20 can determine that its manufactured materials can be ordinary steel, stainless steel, engineering plastics, fiberglass etc. according to the size for the treatment of capacity, looks the pH value decision of treat liquid.
The base plate 11 of casing 20 is obliquely installed, so that solid particle condenses to lowest part.Casing 20 inner route clapboards 6 are separated into two chambers, i.e. first chamber 3 and second chamber 7, and the bottom of dividing plate 6 is provided with the seabed pipe 14 that is communicated with first chamber 3 and second chamber 7.
Top in first chamber 3 and second chamber 7 is respectively arranged with oil spilling groove 5.Two oil spilling grooves 5 are separately positioned on the both sides of dividing plate 6, and oil spilling groove 5 is provided with the dentation breach with dividing plate 6 opposing sideplates upper end, and oil spilling groove 5 is provided with oil drain out 4, is used for oil spilling.
Lowest part on the base plate 11 of first chamber 3 and second chamber 7 is respectively arranged with slag-drip opening 13, is used for deslagging.
Bottom in first chamber 3 is provided with heater.Heater has two covers, arranges up and down, and a cover is an electric heater unit 18, and another set of is steam heater 16.The all tortuous setting of heating tube of two cover heaters is to increase heating surface (area) (HS.The outside of casing 20 is import and export pipes that electrical heating and steam add, and in the porch of steam or hot water heating tube, electric control valve 17 is installed.
The sidewall of first chamber 3 is provided with vertical guiding gutter 2, and the upper end of guiding gutter 2 is a liquid-inlet 1.Be provided with thermocouple 19 in first chamber 3, be convenient to control temperature.Also be provided with liquid level gauge 15 on the sidewall of first chamber 3, with the control liquid level.
Be provided with the vertical guiding gutter 2 that is fixed on the dividing plate 6 in second chamber 7, guiding gutter 2 covers outside the mouth of pipe of seabed pipe 14.Middle part in second chamber 7 is provided with filtering material 12, the PP cotton nonwoven fabrics of filtering material 12 for having the quaternary ammonium salt coating.Top in second chamber 7 is provided with overflow launder 8, the bottom of overflow launder 8 is provided with the outlet pipe 10 that leads to bottom in second chamber 7, and outlet pipe 10 is provided with two, and the upper end of outlet pipe 10 is stretched in the overflow launder 8, and be the zigzag bending, the top of overflow launder 8 is provided with and effluxes mouth 9.
The operation principle of the present utility model and the course of work are as follows: the surface-treated degreasing of need handling, rust cleaning liquid, utilize high-order drop or pump into pump in first chamber 3 of casing 20.After liquid is filled whole box body 20, start heater, if electric heater unit 18, attention must could start by the liquid tankful, otherwise the electrical heating meeting burns out; If adopt the steam heater 16 of hot water or steam, can start electric control valve 17(or solenoid valve), with thermocouple 19 temperature is controlled at 70-80 ℃.The main purpose of heating is a breakdown of emulsion usefulness, if it is not high to enter in the liquid emulsion content, can not need heating demulsification type.Liquid is through breakdown of emulsion, and little oil bloom are condensed into the oil spilling groove 5 that the larger oil droplet come-up enters band dentation breach, and oil mass adopts manual method of discharge oil extraction for a long time in oil spilling groove 5.General heating demulsification type, liquid must stop 20-30 minutes in first chamber 3, therefore must control the flow of liquid.
Solid matter in the liquid is deposited to the bottom of first chamber 3 automatically, because the base plate 11 of first chamber 3 tilts, solid particle condenses to lowest part, every day deslagging once, the deslagging time was controlled at 2-5 minutes, what are definite to see in the liquid solids content.
Liquid in first chamber 3 is through after the heat treated, most of oil slick reaches removal, cleaner liquid enters second chamber 7 from first chamber 3 by seabed pipe 14, because two chambers are UNICOMs, along with liquid has certain time of staying in first chamber 3, therefore enter the interior oil of liquid of second chamber 7, because proportion is lighter than water, add oil viscosity bigger (15-25 li pools), therefore can condense rapidly and float, enter the oil spilling groove 5 of band dentation breach, oil mass adopts manual method of discharge oil extraction for a long time in oil spilling groove 5.
Filtering material 12 in second chamber 7 below the overflow launder 8, adopt the PP cotton material to make, PP is cotton itself to have oil absorptive function, but pass through with 95% polyvinyl alcohol emulsion, after adopting quaternary ammonium salt crosslinking agent crosslinking curing, form the hydrophilic filter material, the water percent of pass increases about 5-8 times, owing on filtering material, form the quaternary ammonium salt coating, and except that hydrophilic, play the effect of sterilization simultaneously, make the degreasing liquid can be not smelly in long-term use, liquid be by the PP cotton nonwoven fabrics, and nonwoven adopts the material of 0.45 micron pore size, being convenient to liquid passes through, because nonwoven is a three-D space structure, when liquid passed through, little oiling produced rapidly and is condensed into larger oil droplet, and float rapidly, reach the purpose that clean water moves to the bottom.
Through handling, the oil in the liquid and other solid matter are removed substantially, and the outlet pipe 10 in second chamber, 7 overflow launders 8 plays siphonal effect, and clean liquid effluxes from the mouth 9 that effluxes of overflow launder 8, and whole operation is finished.
The utility model is simple in structure, and is easy to operate, and one-time investment is low, floor space is little, does not need to add in the medicament and cohesion, does not need to use demulsifier, can utilize the steam heat, the hot water thermal that produce in the process of factory production, most of employing manual operations, operating cost is low.
The utility model wide accommodation is washed no matter liquid is alkali cleaning, pickling, ultrasonic wave, does not all need to adjust pH value.The utility model makes the rinse water of surface treatment industry discharge once from original 3 months, extends to half a year or 1 year discharging once, and oil-water separation is good.
