Description

Technical Field

[0001] This utility model relates to the field of metallurgical pickling equipment technology, specifically to a pickling unit edge blowing device. Background Technology

[0002] In strip pickling production lines, push-pull pickling units are among the most widely used. Push-pull pickling units primarily rely on the clamping rollers of the uncoiler to advance the strip. Once the strip head is bitten and positioned by the coiler, a shallow-trough turbulent pickling process is used to pickle the advancing strip. Then, the strip is squeezed dry by squeeze rollers, removing the reaction products and impurities from the strip surface. Finally, the strip surface is cleaned in a spray tank. Specifically, traditional cleaning technology involves equipping the push-pull pickling unit with a blowing device at the spray tank outlet, which sprays compressed air onto the cleaned strip in opposite directions to remove residual water from the upper and lower surfaces.

[0003] For example, patent announcement number CN221453849U discloses a blow-edge device for a pickling unit, including a working platform, a guiding mechanism, a driving mechanism, and air knives and air knife frames. The guiding mechanism and driving mechanism are both mounted on the working platform. There are two air knife frames, each with two air knives arranged vertically. The two air knife frames are slidably mounted on the guiding mechanism, and are symmetrically arranged about the midpoint of the guiding mechanism. The driving mechanism is connected to both air knife frames and drives them to move simultaneously towards each other or away from each other on the guiding mechanism. According to this design, the blow-edge device for the pickling unit can adjust the distance between the two air knife frames, thereby adjusting the distance in real time according to the width of the strip steel during production, thus optimizing the blow-edge effect after pickling. Furthermore, the blow-edge device uses automated control to achieve dynamic adjustment, reducing the operator's workload and improving strip steel production efficiency.

[0004] However, the above-mentioned technology only blows on the upper and lower surfaces of the steel strip, but the blown water is easy to remain on both sides of the steel strip, and it is impossible to remove the water from both sides of the steel strip; therefore, the market urgently needs to develop a pickling unit edge blowing device to help people solve the existing problems. Utility Model Content

[0005] The purpose of this utility model is to provide a pickling unit edge blowing device to solve the problem in the above-mentioned background technology that the edge blowing device only blows the upper and lower surfaces of the steel strip, but the blown water is easy to remain on both sides of the steel strip and cannot remove the water on both sides of the steel strip.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pickling unit edge blowing device, comprising a support platform, on both sides of the upper surface of the support platform being fixedly connected to a second support column, on both the upper and lower ends of the inner end faces of the two second support columns being fixedly connected to rectangular fixing seats, on the two horizontally symmetrical rectangular fixing seats on the two second support columns being connected to a V-shaped air knife nozzle at their front ends, on the middle of the outer end faces of the two second support columns being fixedly connected to an inclined support plate, on the middle of the inner end faces of the two inclined support plates being fixedly connected to an electrically controlled telescopic rod, on the telescopic ends of the two electrically controlled telescopic rods being fixedly connected to an mounting plate in the middle between the two V-shaped air knife nozzles, and on the middle of the inner side of the two mounting plates being fixedly connected to a flat nozzle.

[0011] Preferably, the front ends of both of the flat nozzles are connected to a second air supply pipe.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment of an edge-blowing device for an acid pickling unit, comprising a support platform 1. Second support columns 2 are fixedly connected to both sides of the middle of the upper surface of the support platform 1. Rectangular fixing seats 201 are fixedly connected to the upper and lower ends of the middle of the inner end faces of the two second support columns 2. Two horizontally symmetrical rectangular fixing seats 201 on the two second support columns 2 are connected to V-shaped air knife nozzles 3 at their front ends. A first air supply pipe 304 is fixedly connected to one side of each of the two V-shaped air knife nozzles 3. The first air supply pipe 304 is connected to an external pressurized air supply device. The upper part is equipped with multiple purge ports 303. The front and rear ends of both sides of the upper surface of the support platform 1 are fixedly connected to the first support column 101. The two horizontally symmetrical first support columns 101 are rotatably connected to the support rollers 102. The strip steel is supported and conveyed by the two support rollers 102. When the strip steel is conveyed between the two V-shaped air knife nozzles 3, the pressurized air supply device supplies air to the V-shaped air knife nozzles 3 through the first air supply pipe 304, so that the multiple purge ports 303 on the V-shaped air knife nozzles 3 blow away the moisture on the upper and lower surfaces of the strip steel, so that the water vapor is blown away to both sides of the strip steel.

[0024] Please see Figure 1 The V-shaped air knife nozzle 3 has connecting plates 301 fixedly connected to both rear ends. The two connecting plates 301 are fixedly connected to the front ends of the two rectangular fixing seats 201 by multiple screws 302. The V-shaped air knife nozzle 3 can be removed by unscrewing the screws 302 on the two connecting plates 301, which is convenient for maintenance and replacement.

[0025] Please see Figure 1 and Figure 3 Two second support columns 2 are each fixedly connected to the middle of the outer end face of an inclined support plate 202. Two inclined support plates 202 are each fixedly connected to the middle of the inner end face of an electrically controlled telescopic rod 204. Two electrically controlled telescopic rods 204 are each fixedly connected to the telescopic end of an electric control rod 204 and to the middle of the space between two V-shaped air knife nozzles 3. Two flat nozzles 5 are each fixedly connected to the middle of the inner side of two mounting plates 4. Two flat nozzles 5 are each connected to the front end of a second air supply pipe 501. The second air supply pipe 501 is connected to an external pressurized air supply device. When the two V-shaped air knife nozzles 3 blow on the upper and lower surfaces of the strip, the two flat nozzles 5 simultaneously blow on both sides of the strip to prevent water vapor blown by the V-shaped air knife nozzles 3 from remaining on the ends of both sides of the strip. By working synchronously with the two electrically controlled telescopic rods 204, the two flat nozzles 5 can be moved to facilitate position adjustment according to different widths of strip.

[0026] Please see Figure 1 and Figure 4The inclined support plate 202 has guide tubes 203 fixedly connected to both the upper and lower ends of the middle part, and guide rods 401 are fixedly connected to both the upper and lower ends of the middle part of the outer end face of the mounting plate 4. The two guide rods 401 extend out of the outer end face of the inclined support plate 202 through the two guide tubes 203 respectively. When the flat nozzle 5 moves, the mounting plate 4 drives the two guide rods 401 to slide along the two guide tubes 203 respectively, guiding the movement of the flat nozzle 5 and ensuring the stability of the movement.

[0027] Working Principle: During operation, the strip steel is conveyed between two V-shaped air knife nozzles 3 by two support rollers 102. An external pressurized air supply device supplies high-pressure gas to the V-shaped air knife nozzles 3 through the first air supply pipe 304. The gas is then ejected through multiple mirror-arranged blowing nozzles 303 on the V-shaped air knife nozzles 3, forming a uniform airflow that simultaneously blows the upper and lower surfaces of the strip steel, removing surface moisture to both sides. Simultaneously, the external pressurized air supply device supplies air to the flat nozzles 5 through the second air supply pipe 501. The airflow from the flat nozzles 5 is angled towards the sides of the strip steel, thoroughly removing any remaining moisture. The extension and retraction of the electrically controlled telescopic rod 204 allows for position adjustment of the mounting plate 4 and the flat nozzles 5 along the guide rod 401 and guide pipe 203 to accommodate strip steel of different widths. The entire edge-blowing process achieves comprehensive moisture removal from the upper, lower, and sides of the strip steel, effectively improving the drying effect.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
