Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide a preparation process of an electric dust collector shell and an electric dust collector applying the shell.
The above object of the present invention is achieved by the following technical solutions:
a preparation process of an electric dust collector shell comprises the following steps:
s1: cleaning the welding surface of the steel plate by using a cleaning agent;
s2: the steel plate is characterized in that a layer of isolating film is coated on the outer surface and the inner surface of a steel plate raw material, and the isolating film comprises the following components in parts by weight:
s3: welding the steel plate coated with the isolating film through a brazing welding surface to obtain a shell body;
s4: spraying a first auxiliary agent on the outer surface of the shell body;
s5: removing the redundant brazing filler metal on the outer surface;
s6: coating a layer of protective coating on the outer surface of the shell body after the brazing filler metal is removed;
and obtaining the shell of the electric dust collector through the six steps.
Through adopting above-mentioned technical scheme, electric precipitator adopts the cleaner earlier to clear up impurity such as greasy dirt on to the steel sheet for among the welding process, the gap between molten brazing filler metal and the steel sheet face of weld reduces, improves welded compactness. In the isolating film coated on the outer surface of the steel plate, the affinity of the zirconium diboride ceramic particles to iron in a molten state is not high, the wetting angle of the iron on the zirconium diboride ceramic particles is small, the graphite has certain lubricity, and the wetting angle of the liquid iron on the graphite is also small, so that the bonding fastening degree of the isolating film and the liquid iron solder is low, and the isolating film is easy to be shoveled without damaging the outer surface of the steel plate. The melting point of graphite is 3652 ℃, the melting point of the zirconium diboride ceramic particles is above 3000 ℃, and the temperature of liquid iron is about 1500 ℃, so that the isolating membrane has good high-temperature resistance and cannot be melted through by the iron at high temperature. The alumina in the isolating membrane is used as aggregate for supporting the membrane layer, the melting point is about 2000 ℃, and the temperature is higher than that of liquid iron. The high-alumina cement is used as a cementing material for forming a coating, and the inorganic binder is used for bonding the coating and the steel plate, so that the bonding strength between the coating and the steel plate is improved.
The invention is further configured to: the cleaning agent comprises the following components in parts by weight:
by adopting the technical scheme, the toluene isobutyl ketone is used as an organic solvent and is mutually soluble with water, the oil stain on the surface of the steel plate has certain dissolving capacity, the sodium dodecyl benzene sulfonate is used as a surfactant to have an emulsifying effect on the oil stain, the oil stain is coated by lipophilic groups to form micelles, and the affinity between the hydrophilic groups and the water is high, so that the oil stain is emulsified and removed from the welding surface of the steel plate, and the oil removing effect is improved. The citric acid may react with the oxide on the surface of the steel sheet to dissolve the oxide, thereby removing the oxide. After oxides and oil stains on the surface of the steel plate are removed, impurities between the brazing filler metal and the steel plate are reduced during welding, and the brazing filler metal is connected with the steel plate more tightly, so that the welding strength is improved.

50-70 parts of boric acid;
60-80 parts of silicic acid;
100 portions of water and 150 portions of water.
By adopting the technical scheme, the aqueous solution of boric acid and silicic acid has certain acidity, the main component of the brazing filler metal is iron, and hydrogen ions in the solution can perform replacement reaction with the iron in the brazing filler metal, so that the brazing filler metal is softened, the bonding degree of the brazing filler metal and the surface of a steel plate is reduced, and the acid solution can not corrode the steel plate due to the fact that the steel plate is coated with the isolating film. Boric acid and silicic acid are weak acids, and the concentration of dissociated ions in the acid solution is low, so that the acidity is weak, and the sealing performance of a welding position is prevented from being influenced by strong corrosion on the brazing filler metal.
The invention is further configured to: the protective coating in the S6 comprises the following raw materials in parts by weight:
by adopting the technical scheme, the zirconium dioxide, the magnesium oxide and the nickel oxide have high temperature resistance and corrosion resistance, so that the protective coating can prevent the shell body from being corroded in the long-term use process, can play a certain heat insulation effect and improve the heat resistance of the steel plate.

By adopting the technical scheme, when the temperature of the spraying solution is lower than 80 ℃, the thermal motion of ions in the spraying solution is not violent enough, and when the spraying solution is sprayed on the brazing filler metal, the softening time is too long, and the efficiency is low. When the temperature of the spraying solution is higher than 110 ℃, the spraying solution is vaporized, and ions in vaporized water vapor move for a distance, so that the spraying solution is too strong in corrosion on the brazing filler metal, and the brazing filler metal on a welding surface is easily damaged. At 80-110 ℃, the activity of ions in the spraying solution is violent, and at high temperature, the dissociation degree of hydrogen ions in weak acid is high, so that the spraying solution has good softening effect on the brazing filler metal. When the spraying time is less than 3 minutes, the softening effect of the spraying solution on the brazing filler metal is insufficient, and when the spraying time is more than 5 minutes, the spraying solution can corrode the brazing filler metal at the welding position, so that the sealing property of the shell is affected.
