Abstract
The invention provides a reversible belt type electrostatic guiding device, which relates to the field of powder electrostatic spraying in the metallurgical industry. The reversible belt type electrostatic guiding device provided by the invention can be used for rapidly cleaning dust accumulated on the metal plate belt.
Description
Technical Field
The invention relates to the field of powder electrostatic spraying in the metallurgical industry, in particular to a reversible belt type electrostatic guiding device.
Background
In the metallurgical industry, powder electrostatic spraying is mostly adopted when color coating is carried out on intermittent steel plates and aluminum plates. Because the baked color-coated plate finished product after powder spraying is convenient to package and transport, a plurality of steel plates and aluminum plates with equal length and width dimensions are orderly stacked in a multi-layer accumulation way, and the number of the steel plates and the aluminum plates is as high as hundreds to thousands. The thickness of the stacked multilayer plates is required to be consistent, the thickness of the powder coating sprayed on each plate is also required to be consistent, otherwise, the stacked plates are uneven in thickness in a long and wide range and uneven in height, and the orderly, reasonable and unified package cannot be realized. Also, for steel coils (bands) or aluminum coils (bands), the number of turns of coils rolled into coiled plates (bands), namely the number of layers is as high as hundreds to thousands, if the thickness of powder coating sprayed on the coils is inconsistent, the thickness of the coiled coils with equal width in the width range is uneven, the coil diameters are inconsistent, and the appearance is unsightly; in addition, the coiled multi-layer plates (belts) bear great tension in the process of coiling, the coiled plates (belts) are tightly tightened, and the later uncoiled and uncoiled plates (belts) have convex-concave deformation due to uneven steel coil, which is not allowed and cannot be used as waste products.
In the electrostatic powder spraying operation, since the plate and the coil area are large, the sprayer needs to spray a large amount of powder simultaneously onto the plate surface, and further a large amount of compressed air is required. Because the spraying device is basically vertical to the plate surface and the rolling surface, the sprayed compressed air carries electrostatic powder to be sprayed to the surface of the steel plate vertically. Wherein a large part of the powder is attached to the surface of the plate coil, and the powder which is not attached to the surface of the plate coil is pressed by compressed air and can horizontally move along the width directions of the plate belt surface to the width edge parts of the plate (belt). Meanwhile, the side of the sprayed board is also provided with powder sprayed by a sprayer.
Because the sprayer is provided with a high-voltage electrostatic electric field, the sprayed powder carries charges. The plate (belt) to be sprayed is grounded, so that the powder carrying charges sprayed by the sprayer corresponds to the positive electrode of a power supply, and the plate (belt) to be sprayed corresponds to the zero electrode. The powder carrying charges sprayed by the sprayer is very easy to combine with the surface of the sprayed plate (belt) and adhere to the surface of the plate (belt) due to the attraction of the electric field; and the charged powder is more likely to adhere to the plate (tape) where the electric field is strong. Since the electric field is much stronger at the tip than at the smooth place for the metal surface, the electric field strength is strongest at the edge of the plate (strip) shaped like a "blade" for the sprayed plate (strip). The charge-carrying powder is more prone to collect toward the edges of the plate (strip). Therefore, for powder electrostatic spraying, the intermittent steel plate edge and the steel coil (strip) edge attract more powder, which causes the paint film on the edge (1-2 mm from the edge) of the plate (strip) after heating and baking to be remarkably thickened, and the paint film is much thicker than the plate surface.
In the prior art, as shown in fig. 1, in order to reduce the powder removed from the plate tape Bian Bupiao, the floating powder is reduced to adhere to the edge of the plate (tape), a single-layer or double-layer long metal plate tape 800 is arranged at a certain distance from the edge of the plate (tape) in parallel and approximately at the same height along the whole length of the spray booth 900, and a relatively strong electric field can be generated by using the sharp tips of the two edges adjacent to the plate (tape), so that the total powder amount at the edge is divided by the tip of the edge of the plate (tape) to be sprayed and the tip of the edge of the single-layer or multi-layer long metal plate (tape), and the powder adhering amount at the edge of the sprayed plate tape is reduced. In addition, the edges of the long metal plate and the strip are sharp, and the distance is relatively short, so that the electric field can compete with the edges of the sprayed plate and the strip, the electric field intensity of the edges of the sprayed plate (strip) can be reduced, the powder adsorption capacity of the edges of the sprayed plate (strip) can be reduced, and the attached powder amount can be reduced. The electrostatic powder sprayed on the edge of the plate (belt) does not substantially thicken.
However, in the actual use process, the spraying time is longer because the spraying room 900 is longer; after a period of operation, a lot of dust is accumulated on the metal plate strip 800, and the metal strip is suspended to cause inconsistent distance between the metal strip and the edge of the sprayed plate strip due to long length and poor rigidity of the metal plate strip 800; in addition, the cleaning is not easy, and the efficiency of spraying operation is seriously affected; also, the deposited powder carries a lot of charge, disabling the metal strip, greatly reducing its ability to reduce the thickness of the powder at the edges of the sprayed strip.
In view of this, the present inventors have conducted repeated experiments to design a reversible belt-type electrostatic guiding device according to production design experience in the field and related fields for many years, so as to solve the problems in the prior art.
