The thick edge reduction purge device of the present invention is used in intermittent or continuous electrostatic powder spraying of plates and strips, and a compressed air nozzle is arranged on the back side edge of the sprayed surface of the running plate and strip, and a high-speed compressed air flow is blown out by the compressed air nozzle to carry away the powder adsorbed on the sprayed side of the edge of the sprayed plate and strip due to the large electric field intensity, thereby reducing the amount of electrostatic spray powder attached to the edge parts of both sides of the plate and strip, and reducing the significant thickening of the paint film on the edge of the sprayed side after baking.
Description
Technical Field
The invention relates to the field of powder electrostatic spraying, in particular to a thick edge reduction blowing device and a powder electrostatic spraying device.
Background
At present, most color-coated plates in China adopt a mode of coating plates and coils by solvent type liquid paint. There are fewer production lines for continuous electrostatic spraying of powder on intermittent steel plates, aluminum plates or steel coils or aluminum coils.
For intermittent steel plates and aluminum plates, a plurality of steel plates and aluminum plates with equal length and width are orderly stacked in a multi-layer accumulating way for the finished products of baked color-coated plates after powder spraying is finished, and the number of the steel plates and the aluminum plates is 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 required to be consistent, otherwise, the thickness of the stacked plates in a long and wide range is uneven, the plates cannot be packaged neatly and reasonably uniformly, and the sprayed plate products are disqualified due to the fact that the plates are deformed locally due to the uneven heights.
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.
For electrostatic powder spraying intermittent plates and continuous coil plates, the sprayer needs to spray a large amount of powder to the plate surface simultaneously due to large plate and coil areas. This requires the use of a large amount of compressed air when spraying the powder. 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 surface of the plate.
The intermittent steel plates and the aluminum plates are required to be orderly stacked from hundreds to thousands of layers of steel plates before being packaged and transported; for steel or aluminum rolls, the roll is rolled into a roll with thousands of layers, the problem that the width of the roll is thicker at the edge than at the middle is marked by the powder coating thickness ≡! Namely, a plurality of layers of intermittent steel plates and aluminum plates which are stacked are tilted at the upper edge part of the width and concave in the middle, and cannot be packaged in order; for the steel coil or the aluminum coil, the edge part is obviously tilted and the middle is concave in the width direction, so that the plate coil is seriously deformed-! In the color coating industry, waste products are determined.
In order to reduce the powder removed by the plate strip Bian Bupiao and to reduce the adhesion of floating powder to the edges of the plate (strip), there is a porous (tube) suction device provided at the edge of the sprayed plate (strip). As shown in fig. 1 and 2, a plurality of suction pipes 101 parallel to each other are arranged in a short distance along the edge of the sprayed strip 2, perpendicular to the running direction 103 of the sprayed strip. The plurality of suction pipes 101 are inserted into a negative pressure main pipe 102.
There are a number of disadvantages to this type of device. Firstly, because the diameter of the powder suction pipe orifice cannot be set too large, otherwise, the negative pressure suddenly drops, the suction force and the powder suction efficiency are low, or the diameter of the main negative pressure pipe is required to be large, and a large pipeline is not suitable to be arranged in a spray booth. The floating range of the powder lifted by the plate and the curled edge is larger and is far larger than the caliber of the powder suction pipe, so that the floating powder cannot be mostly sucked into the powder suction pipe, namely the powder suction effect and the powder suction efficiency of the powder suction pipe are poor. And secondly, a plurality of powder suction pipes are arranged in parallel along the main negative pressure pipe, and the negative pressure generating ports of the main negative pressure pipe can only be arranged at two ends of the main pipe or a plurality of negative pressure generating ports are arranged in a limited way along the length of the main pipe. The negative pressures of the pipe orifices of the powder suction pipes along the length direction of the plate belt are inconsistent, and the difference is larger. The uneven powder sucking capacity along the length direction of the plate belt can be seriously caused. In addition, most of the existing continuous coiled plate electrostatic powder spraying production lines enter a spraying room in a horizontal state, and as the continuously sprayed steel coil or aluminum coil horizontally enters the spraying room, the plate belt cannot be provided with a carrier roller or a lifting device, and therefore the plate belt naturally hangs and is not flat in the spraying process in the spraying room; and the plate belt is slightly floated in the running process, and for the powder suction pipe orifices which are arranged in parallel on the main negative pressure pipe, the pipe material is a hard pipe, so that the plate belt is hard to be directly opposite to the edge part of the overhanging plate belt, and the powder suction efficiency is reduced. Thirdly, the electric field at the edge of the plate (belt) cannot be reduced by the method, and the problem that the paint film at the edge of the plate is obviously thickened can be hardly effectively reduced.

Detailed Description
In order to more clearly illustrate the present invention, the present invention will be further described with reference to preferred embodiments. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and that this invention is not limited to the details given herein.
The whole idea of the invention is as follows: the compressed air nozzle is arranged on the opposite side of the sprayed surface of the sprayed plate and strip, and high-speed compressed air is blown out from the compressed air nozzle to the opposite side of the sprayed surface of the plate and strip, so that the compressed air can be quickly blown off from the edge of the plate and strip along the transverse direction of the plate and strip edge, high-speed air flow is generated at the edge of the plate and strip, a negative pressure area is generated around the high-speed air flow, and ambient air can flow into the negative pressure area due to negative pressure, so that moving air flow is formed. The air flow blows and blows away part of superfluous floating powder attached to the upper edge part of the plate; it can also be explained that the high-speed compressed air flow will pull the surrounding air to move, so that the electrostatic powder attached near the edge of the spraying side plate belt will be disturbed, and part of the powder will be pulled away or blown away by the air. The thickness of paint film at the edge of the plate strip after baking is reduced when the thickness of the powder thickened at the edge of the plate strip to be sprayed is reduced. The problem of thickening of the paint film at the edge of the strip, namely thick edge, is greatly relieved, and the problem of edge bulge of the intermittent steel plate which is overlapped by multiple layers is greatly relieved, and the phenomena of curling of the steel coil and aluminum curling of the multiple layers are reduced.
Therefore, the whole scheme provided by the invention is as follows: a thick edge reducing and blowing device is used for spraying intermittent or continuous powder static electricity on a plate and is positioned at a compressed air nozzle at an outlet of the sprayed plate and strip in the running direction outside the back side and the spraying range of the sprayed surface of the sprayed plate and strip, and the compressed air nozzle sprays air towards the edge of the sprayed plate and strip.
Wherein the compressed air nozzle is positioned at the edge of the sprayed strip perpendicular to the running direction to mainly purge away excess powder at the edge of the sprayed strip.
Preferably, the compressed air nozzle comprises a group of compressed air nozzles located at one side edge of the sprayed strip perpendicular to the running direction; or the compressed air nozzles comprise two groups positioned at two side edges of the sprayed plate strip perpendicular to the running direction. That is, the compressed air nozzle may be provided on one side to be matched with other powder removing devices, or may be provided on both sides.
It is further preferred that each set of compressed air nozzles comprises a plurality of compressed air nozzles, preferably 1 to 20, arranged side by side in the direction of travel of the sprayed strip. The specific number can be set by those skilled in the art according to the powder removing effect.
Preferably, the distance between the air nozzle and the edge of one side of the plate strip to be sprayed, which is close to the air nozzle, is-50-100 mm. So that the air can be effectively sprayed on the edge of the sprayed plate belt. Wherein, the air jet is positive when being positioned at the inner side of one side edge of the adjacent sprayed plate belt, and is negative when being positioned at the outer side.
Preferably, the distance between the air nozzle of the compressed air nozzle and the back side surface of the sprayed plate strip is 5-200 mm.
Preferably, the air injection direction of the compressed air nozzle forms an angle of-30 degrees to 80 degrees with the vertical direction of the sprayed plate strip surface. I.e. may be vertical or non-vertical. Further, when the compressed air nozzle is not vertical, the air injection direction of the compressed air nozzle is at an angle within-30 degrees to 80 degrees towards the edge direction of the sprayed plate strip. Wherein the blowing from the middle to the edge of the plate strip is positive, and the blowing from the edge to the middle is negative.
Preferably, the compressed air source pressure of the compressed air nozzle is 0.1-0.8 MPa.
In particular, as shown in fig. 3 and 4, a compressed air nozzle 1 is disposed at an outlet of the spraying range in the running direction of the sprayed strip 2 on the back side of the sprayed strip spraying surface 6, and the compressed air nozzle 1 sprays air toward the sprayed strip 2.
As shown in fig. 3 and 4, the compressed air nozzles 1 are located at the edges of the sprayed strip 2 perpendicular to the running direction, including two groups located at both side edges. Each set of compressed air nozzles 1 comprises 3 compressed air nozzles 1 arranged side by side in the direction of travel of the sprayed strip 2.
As shown in fig. 4, the air jet of the compressed air nozzle 1 is located inside the edge of the sprayed strip 2 perpendicular to the running direction, within 100mm of this edge, which is indicated by 4 in fig. 4. Furthermore, the air jet of the compressed air nozzle 1 can also be located outside the edge of the sprayed strip 2 perpendicular to the running direction and within 50mm of this edge is good. Therefore, the distance between the air nozzle 1 and the edge of the sprayed plate strip is-50-100 mm; negative, i.e. on the outside, positive on the inside.
The vertical distance between the air jet of the compressed air nozzle 1 and the back side of the sprayed surface of the sprayed board belt 2 is 5-200 mm, and the distance is 3 marked in fig. 4.
The direction of the air jet of the compressed air nozzle 1 is at an angle of 5 marked in fig. 4 and within-30 deg. to 80 deg. to the vertical direction of the surface of the sprayed strip 2. It will be readily appreciated by those skilled in the art that the angle may be 0 deg. with the direction of the air jet from the compressed air nozzle 1 being perpendicular to the surface of the sprayed strip 2.5 is shown in fig. 4 as 30 deg., in this case, the spray jet is directed from the middle to the edges of the strip being sprayed; it will be readily appreciated that when the nozzle is inclined to spray from the edge of the sprayed strip to the centre, the angle is negative and the negative angle is more effective within 30 °. Preferably, the compressed air nozzle 1 has a compressed air source pressure of 0.1 to 0.8MPa, which has produced an air flow of a certain intensity.
It is easy to understand by those skilled in the art that the number, position, etc. of each group of compressed air nozzles can be adjusted according to the specific powder removing effect on the basis of the present preferred embodiment. At the same time, the compressed air pressure, the distance from the edge, the distance from the back, etc. can be adjusted.
In addition, for the simultaneous movement of the plate strips in the direction perpendicular to the running direction, i.e. the width direction, a position follower can also be provided, ensuring that the nozzle position and the plate strip width position are relatively fixed.
In the preferred embodiment of fig. 3 and 4, the strip being sprayed is in a horizontal, natural suspension, and may be vertical, inclined or horizontal, with the nozzles being correspondingly positioned on opposite sides of the spray surface in accordance with the concepts of the present invention.
The invention also provides a powder electrostatic spraying device based on the above, which comprises the thick edge reduction purging device. The thick edge reducing and blowing device provided by the invention is arranged in the original electrostatic spraying device, so that the powder adhering amount of the edge part of the sprayed plate can be effectively reduced, and the problem of thickening of the edge part of the electrostatic powder spraying plate is solved.
It should be understood that the foregoing examples of the present invention are provided merely for clearly illustrating the present invention and are not intended to limit the embodiments of the present invention, and that various other changes and modifications may be made therein by one skilled in the art without departing from the spirit and scope of the present invention as defined by the appended claims.
