Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Figure 1: in order effectively to remove the gas in coating solution, improve coating quality, the utility model comprises filter 2, the liquid outlet of described filter 2 is connected with the inlet of exhaust tank 3, the liquid outlet of exhaust tank 3 is connected with the inlet of surge tank 4, the liquid outlet of surge tank 4 is connected with the inlet of the second delivery pump 5, and the liquid outlet of the second delivery pump 5 is connected with the inlet of heat exchanger 7, and the liquid outlet of heat exchanger 7 is connected with the inlet of froth breaker 8.
Particularly, the inlet of described filter 2 is connected with the liquid outlet of the first delivery pump 1.Coating line is for water aqua type or solvent type coating solution are coated on through on chemically treated aluminium sheet, and conventionally the thickness of coating only has between 20 to 40 microns, coating speed can reach 60 meters per minute.
The nitrogen or the oxygen that in coating solution process for preparation, have certain solubility are dissolved in coating solution, single Degassing Technology efficiency is not high, or practicality is not high, as the temperature that heats coating solution exceedes 30 degree, can accelerate the volatilization of solvent, cause being coated with piebald, so the heating-up temperature of general coating solution can not be too high, correspondingly increased degassed difficulty.
In the utility model embodiment, coating solution is transported to filter 2 with the first delivery pump 1 from storage tank, filter 2 is not communicated with atmosphere, after filtering, filter 2 enters in exhaust tank 3, exhaust tank 3 is connected with atmosphere, owing to having lowered the pressure of solution, and the also corresponding minimizing of dividing potential drop of dissolved gases in coating solution (nitrogen or oxygen), the solubility of gas in solution is reduced to a certain extent like this, and gas is overflowed from solution., when the pressure that froth breaker 8 is carried at solution reaches setting pressure, can automatically open, residual gas is further discharged meanwhile.
Further, the liquid outlet of described the second delivery pump 5 is connected with the inlet of heat exchanger 7 by membrane separator 6.Particularly, in order further to improve the degasifying effect of solution, the coating solution membrane separator 6 of flowing through again after degassed by reducing pressure, mandrel inside at membrane separator 6 is connected into vacuum, and because the aperture of film is very tiny, dissolved gas can pass multilayer film, siphoned away by vacuum, liquid can not penetrate multilayer film, and the oxygen content in final solution can on-line monitoring, thereby guarantees that whole process obtains effective monitoring.
Film separates will reach best degasifying effect, multiple membrane separators 6 can also be together in series, and vacuum need to be adjusted to specified operating range, tries one's best membrane separator 6 near being arranged on terminal use.In the utility model embodiment, membrane separator 6 can adopt existing film separating structure, and membrane separator 6 can be realized the separation of gas-liquid, specifically repeats no more.
As shown in Figure 2, Figure 3 and Figure 4, described surge tank 4 comprises buffering tank body 9, the end of described buffering tank body 9 is provided with buffering feed tube 10 and buffering drain pipe 11, and described buffering feed tube 10 and buffering drain pipe 11 are all connected with the cavity in described buffering tank body 9; One end of buffering drain pipe 11 forms the liquid outlet of surge tank 4, and the other end of buffering drain pipe 11 stretches in buffering tank body 9.
Described buffering drain pipe 11 is positioned at the center of buffering tank body 9, and the degree of depth that buffering drain pipe 11 stretches in buffering tank body 9 is less than the height that cushions tank body 9.
In the utility model embodiment, in use, the one end that buffering tank body 9 correspondences is arranged to buffering feed tube 10 and buffering drain pipe 11 is downward, when coating solution is in the time that buffering tank body 9 is interior, is conducive to gas and overflows from solution.The axis of buffering drain pipe 11 is located along the same line with the axis of buffering tank body 9, and the body of buffering drain pipe 11 extend in buffering tank body 9 always.
As shown in Figure 5, described froth breaker 8 comprises froth breaking tank 13, one end of described froth breaking tank 13 is provided with froth breaking drain pipe 15 and froth breaking feed tube 14, described froth breaking drain pipe 15 is positioned at the center of froth breaking tank 13, froth breaking feed tube 14 tilt distribution are on froth breaking tank 13, one end of froth breaking feed tube 14 is as the inlet of froth breaker 8, and the other end of froth breaking feed tube 14 stretches in froth breaking tank 13.
One end that described froth breaking feed tube 14 stretches into froth breaking tank 13 has bending, and froth breaking feed tube 14 end that is positioned at froth breaking tank 13 has the horn mouth 12 of opening upwards.Top in described froth breaking tank 13 is provided with the equilibrated valve mounting groove 16 for setting pressure balanced valve.
In the utility model embodiment, the structure of the structure of froth breaker 8 and surge tank 4 is similar, and the volume of froth breaker 8 is less than the volume of surge tank 4.Coating solution flows into froth breaking tank 13 inside via dress froth breaking feed tube 14, and is assigned to froth breaking feed tube 14 around, finally flows out by the froth breaking drain pipe 15 of froth breaking tank 13 bottoms.
Because solution has certain distance at the upper space of froth breaking tank 13, in the process that solution down flows in the 14 rear continuation of outflow froth breaking feed tube, be partly dissolved gas because the density of density ratio solution is much smaller, as long as the height of froth breaking feed tube 14 in froth breaking tank 13 is enough high, gas just has enough time and up overflows from solution, until upper space.In the time that the pressure in froth breaking tank 13 reaches setting pressure, the equilibrated valve being arranged in equilibrated valve mounting groove 16 can be opened, and discharges gas with this.
The utility model coating solution is after filter 2, exhaust tank 3, buffer 4, membrane separator 6, heat exchanger 7 and froth breaker 8 effects, can effectively remove the gas in coating solution, compact conformation, improves coating quality, wide accommodation, safe and reliable.
