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 turnover belt type static guiding device provided by the invention can quickly clean dust accumulated on the metal plate strip.
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, when color coating is performed on intermittent steel plates and aluminum plates, a powder electrostatic spraying mode is mostly adopted. Because the baked finished color-coated sheet after powder spraying is convenient for packaging and transportation, a plurality of steel plates and aluminum plates with the same length and width need to be accumulated in multiple layers and stacked in order, and the number of the steel plates and the aluminum plates reaches hundreds to thousands. The thickness of the stacked multilayer boards is required to be consistent, the thickness of the powder coating sprayed on each board is required to be consistent, otherwise, the thickness of the stacked boards is uneven in the length and width range, the stacked boards are uneven in height, and uniform packaging cannot be realized neatly and reasonably. Similarly, for steel coils (strips) or aluminum coils (strips), because the number of turns of coils (i.e., the number of layers) wound into a coil (strip) is hundreds to thousands, if the thickness of the powder coating sprayed on the coil (strip) is inconsistent, the constant-width steel coils wound together have uneven thickness within the width range, the coil diameter is inconsistent, and the appearance is unsightly; in addition, the multi-layer plates which are rolled together are tightly wound due to the fact that the plates (strips) bear large tension in the rolling process, and the plates (strips) which are subsequently uncoiled and expanded are deformed in a convex-concave mode due to the fact that steel coils are uneven in a convex-concave mode, so that the multi-layer plates are not allowed to be used as waste.
In the electrostatic powder coating operation, since the area of the plate and the roll is large, the coating device needs to simultaneously spray a large amount of powder toward the plate surface, and further needs to use a large amount of compressed air. Because most of the spraying devices are basically vertical to the plate surface and the rolling surface, the sprayed compressed air carries the electrostatic powder to be vertically sprayed to the surface of the steel plate. Most of the powder is attached to the surface of the plate roll, and the powder which is not attached to the surface of the plate roll is pressed by compressed air and can horizontally move along the two sides of the width of the surface of the plate strip to the edge of the width of the plate (strip). At the same time, the edge of the sprayed plate surface is sprayed with powder by a sprayer.
The sprayer has high voltage electrostatic field to make the sprayed powder carry electric charge. The plate (strip) to be painted is grounded, so the powder with charge sprayed by the sprayer is equivalent to the positive pole of the power supply, and the plate (strip) to be painted is equivalent to the zero pole. Due to the attraction of the electric field, the powder which is sprayed by the sprayer and carries charges is easily combined with the surface of the sprayed plate (belt) and is adhered to the surface of the plate (belt); and the charged powder adheres more readily to the plate (strip) where the electric field strength is present. Since the electric field is much stronger at the point than at the smooth point for a metal surface, the electric field strength is strongest at the edge of the plate (strip) shaped like a "knife edge" point for the plate (strip) being sprayed. The charge-carrying powder is more likely to collect toward the plate (belt) edges. Therefore, for powder electrostatic spraying, the powder absorbed by the edge of the interrupted steel plate and the edge of the steel coil (strip) is more, so that the paint film at the edge (within 1-2 mm from the edge) of the plate (strip) is obviously thickened after heating and baking, and is much thicker than the plate surface.
In the prior art, as shown in fig. 1, in order to reduce the powder floating out of the edges of the plate strip and reduce the adhesion of the floating powder on the edges of the plate (strip), a single-layer or double-layer elongated metal plate strip 800 along the full length of a spray chamber 900 is arranged at the edges of the plate (strip) at a certain distance and approximately at the same height in parallel, and the sharp tips of two adjacent edges of the plate (strip) can generate a stronger electric field, so that the total powder amount of the edges is divided by the edge tips of the plate (strip) to be sprayed and the edge tips of the single-layer or multi-layer elongated metal plate (strip), and the powder applying amount of the edges of the plate (strip) to be sprayed is reduced. In addition, because the edges of the long metal plates are sharp and are close to each other, the edges compete for an electric field with the edges of the sprayed plates (strips), so that the electric field intensity of the edges of the sprayed plates (strips) is reduced, the powder adsorption capacity of the edges of the sprayed plates (strips) is reduced, and the attached powder quantity is also reduced. The electrostatic powder sprayed on the edge of the plate (strip) does not substantially thicken.
However, in the actual use process, the spraying time is also longer due to the longer spraying room 900; after a period of operation, a lot of dust is accumulated on the metal plate strip 800, and the metal strip is too long and has poor rigidity, so that the metal strip is overhung to cause the edge distance between the metal strip and the sprayed plate strip to be inconsistent; in addition, the cleaning is not easy, and the efficiency of the spraying operation is seriously influenced; also, the accumulated powder carries a lot of charge, disabling the strip, greatly reducing its ability to reduce the thickness of the powder at the edge of the sprayed strip.
In view of the above, the inventor designs a reversible belt-type electrostatic guiding device through repeated experiments according to production design experiences in the field and related fields for many years, so as to solve the problems in the prior art.
