[0002] In the field of metal processing, strip steel, as an important basic material, is widely used in industries such as construction, automobiles, and home appliances. During the production process, impurities such as oil and rust often adhere to the surface of the strip steel. These impurities not only affect the appearance quality of the strip steel, but may also cause product quality problems in the subsequent processing. Therefore, it is very important to thoroughly clean the surface of the strip steel.

[0003] At present, the surface of steel strip is usually cleaned by pickling process, and the rust and oil on the surface of steel strip are removed by acid in the pickling tank. However, acid and other impurities often remain on the surface of steel strip after pickling, which requires further cleaning and drying. The existing post-pickling treatment of steel strip is mostly simple spraying and then blowing dry. This treatment method has obvious shortcomings. Specifically, simple spraying cannot completely remove the residues and impurities on the surface of steel strip, especially for stubborn stains and oil stains. The effect is even more limited, which not only affects the appearance quality of steel strip, but also may have adverse effects on subsequent processing. In addition, the hot air drying method often has low drying efficiency for residual liquid on the steel strip, and some areas may have residual moisture, which also affects the quality of the steel strip and the subsequent processing effect.

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0024] The embodiment of the present application provides a push-pull pickling line strip steel surface cleaning device, which can solve the problem in the related art that the strip steel post-pickling treatment method is mostly spraying followed by blowing dry, so that the residue on the strip steel surface cannot be completely removed and the drying efficiency is low.

[0025] See also Figure 1-Figure 3A push-pull pickling line strip steel surface cleaning device comprises: a pickling tank 1, a cleaning tank 2 and a drying tank 3 connected in sequence, wherein the cleaning tank 2 is provided with a cleaning mechanism 4 for cleaning the strip steel, and the drying tank 3 is provided with a dehumidifying mechanism 5 for drying the strip steel; the cleaning mechanism 4 comprises a group of cleaning rollers 41, a driving member 42 and a group of brushing plates 43, wherein a group of the cleaning rollers 41 are relatively arranged in the cleaning tank 2 and are used to brush the upper and lower surfaces of the strip steel, and the driving member 42 is connected to the cleaning rollers 41, It is used to drive the cleaning roller 41 to rotate. A group of the brush plates 43 are relatively arranged inside the cleaning tank 2 and are used to brush both ends of the strip. The dehumidification mechanism 5 includes an air supply plate 51 relatively arranged inside the drying tank 3, and a hot air supply pipe 52. A plurality of nozzles 53 are relatively arranged on the air supply plate 51. The hot air supply pipe 52 is connected to the air supply plate 51 and is used to send hot air into the air supply plate 51. A plurality of adsorption rollers 54 are relatively rotated inside the drying tank 3 and are used to wipe the upper and lower surfaces of the strip.

[0026] It should be noted that both ends of the pickling tank 1, the cleaning tank 2 and the drying tank 3 are provided with conveying holes adapted to the strip steel, and two adjacent conveying holes are interconnected.

[0027] The cleaning roller 41 includes a rotating shaft rotatably arranged inside the cleaning tank 2, a roller is arranged on the rotating shaft, and a plurality of soft bristles are arranged on the roller. The cleaning roller 41 is located at the upper and lower sides of the conveying hole.

[0028] The working process of the push-pull pickling line strip steel surface cleaning equipment starts with the strip steel entering the pickling tank 1, and then passes through the cleaning tank 2 and the drying tank 3 in sequence.

[0029] The strip steel is immersed in acid in the pickling tank to remove impurities such as rust and oil on the surface. The pickling liquid is usually a strong acid solution that can quickly and effectively remove the oxide layer and other impurities on the metal surface.

[0030] The cleaning roller 41 in the cleaning mechanism 4 is driven to rotate by the driving member 42. The cleaning roller contacts the surface of the strip and brushes the residual acid and impurities on the upper and lower surfaces of the strip through the rotating action. At the same time, the brushing plates 43 are located on both sides of the cleaning tank to brush both ends of the strip to ensure that the edges of the strip are also cleaned.

[0031] The cleaning tank can be filled with cleaning liquid or clean water, which cooperates with the cleaning roller and the scrubbing plate to further improve the cleaning effect.

[0032] The hot air supply pipe 52 in the dehumidification mechanism 5 delivers hot air into the air supply plate 51, and then is evenly sprayed on the surface of the strip through the nozzle 53. The function of the hot air is not only to remove moisture from the surface of the strip, but also to further improve the drying effect and prevent the strip from rusting or other quality problems during subsequent processing. The adsorption roller 54 is located in the drying tank and wipes the upper and lower surfaces of the strip through a rotating action to further remove residual moisture and humidity. A filter is provided at the top opening of the drying tank to allow moisture to be discharged while preventing dust and other impurities from entering.

[0033] In actual use, the combined use of cleaning rollers and brush plates can comprehensively and thoroughly clean the surface of the strip, remove residual acid and impurities, and improve the cleanliness of the strip.

[0034] At the same time, hot air is evenly sprayed on the surface of the strip through the nozzle, and combined with the wiping effect of the adsorption roller, the strip can be evenly dried to prevent moisture residue.

[0035] The equipment has a compact structure and is easy to operate. It can meet the surface cleaning needs of strip steel of different specifications and materials, and improve production efficiency and product quality.

[0036] It can be understood that in this embodiment, a drying chamber is provided inside the drying tank 3, the top of which is open, and a filter screen is clamped at the opening, so that the moisture is discharged.

[0037] The cleaning tank 2 is provided with a cleaning chamber inside, which is in a sealed state as a whole to prevent the cleaning liquid from leaking out.

[0038] Specifically, the driving member 42 in this embodiment includes a shell 421 arranged on the cleaning tank 2, a driving motor 422 is arranged on the shell 421, one end of the cleaning roller 41 extends into the shell 421, the output shaft of the driving motor 422 is connected to one end of any cleaning roller 41, and the cleaning roller 41 is provided with a gear 423 located inside the shell 421, and the two gears 423 are meshed with each other.

[0039] In this embodiment, the driving member 42 of the cleaning mechanism 4 ensures that the cleaning roller 41 can rotate smoothly, thereby effectively scrubbing the surface of the steel strip.

[0040] When the driving motor 422 is started, its output shaft is directly connected to the gear 423 at one end of one of the cleaning rollers 41 and starts to rotate. Since the two gears 423 are meshed with each other, when one gear 423 rotates, the other gear 423 will also rotate at the same speed but in the opposite direction. Through this gear transmission system, the two cleaning rollers 41 can rotate in opposite directions, thereby more comprehensively brushing the upper and lower surfaces of the strip.

[0041] One end of the cleaning roller 41 extends into the interior of the housing 421 and is fixedly connected to the gear 423 . When the gear 423 rotates, the cleaning roller 41 will also rotate accordingly.

[0042] A plurality of soft bristles are provided on the cleaning roller 41. When the cleaning roller 41 rotates, the soft bristles come into contact with the surface of the steel strip, and the residual acid and impurities on the surface of the steel strip are scrubbed through the rotating action.

[0043] In this embodiment, the scrubbing plate 43 comprises a mounting plate 431 disposed on the side wall of the cleaning tank 2, a plurality of soft bristles 432 are disposed on the mounting plate 431, and the scrubbing plate 43 is located on both sides of the conveying hole.

[0044] The scrubbing plate 43 is used to scrub both ends of the steel strip to ensure that the steel strip is fully cleaned during the cleaning process.

[0045] The mounting plate 431 provides a sturdy foundation for mounting the soft bristles 432.

[0046] The soft bristles 432 are made of a soft and elastic material and can gently but effectively clean both ends of the steel strip.

[0047] The brushing plate 43 is located in the cleaning tank 2 and is installed on both sides of the conveying hole. The purpose of this design is to ensure that when the strip enters or leaves the cleaning tank 2 through the conveying hole, both ends of the strip can be brushed by the soft bristles 432 on the brushing plate 43.

[0048] When the steel strip enters the cleaning tank 2 through the conveying hole, its two ends will contact the soft bristles 432 on the brush plate 43. As the steel strip moves, the soft bristles 432 will gently brush the two ends of the steel strip to remove residual acid, oil and other impurities.

[0049] Furthermore, in this embodiment, the air supply plate 51 has a hollow chamber inside, and the nozzle 53 is connected to the air supply plate 51, and the nozzle 53 is close to the end away from the air supply plate 51. The nozzle 53 is located at the upper and lower parts of the delivery hole, and the spray port of the nozzle 53 is inclined to one side of the delivery hole.

[0050] The air supply plate 51 has a hollow chamber inside for accommodating and transferring hot air. The hot air enters the hollow chamber of the air supply plate 51 through the hot air supply pipe 52. The nozzles 53 are connected to the hollow chamber of the air supply plate 51 to ensure that the hot air can be evenly distributed to each nozzle 53.

[0051] The nozzles 53 are located at the upper and lower parts of the conveying hole. Such a layout can ensure that the hot air acts on the upper and lower sides of the strip at the same time to achieve all-round drying.

[0052] The ends of the nozzles 53 away from the air supply plate 51 are moved closer together to form a relatively compact spraying area. Such a design helps to enhance the concentration effect of hot air and improve the drying efficiency.

[0053] The spray port of the nozzle 53 is inclined toward one side of the conveying hole, so that when the hot air is sprayed out, an oblique flow can be formed to better cover the surface of the strip, especially the edge of the strip, to ensure that the strip is evenly dried.

[0054] In actual operation, when the hot air enters the hollow chamber of the air supply plate 51 through the hot air supply pipe 52, the hot air is evenly distributed to each nozzle 53. The nozzle 53 sprays the hot air on the surface of the strip in an oblique manner. After the hot air comes into contact with the moisture on the surface of the strip, the moisture is evaporated and taken away, thereby achieving drying of the strip.

[0055] During the drying process, the steel strip moves in the conveying hole, and the surface of the steel strip is evenly dried through the spraying action of the nozzles 53 on the upper and lower sides.

[0056] Preferably, in this embodiment, the hot air supply pipe 52 includes a main pipe and several branch pipes, the main pipe is arranged outside the drying tank 3, and the several branch pipes are sequentially arranged on the main pipe, and the other end of the branch pipe is connected to the air supply plate 51.

[0057] The hot air supply pipe 52 consists of a main pipe and several branch pipes. The main pipe is arranged outside the drying tank 3 and connected to the external heating pipe, while the branch pipes are connected to the main pipe in turn. The other end of the branch pipe is connected to the air supply plate 51. When the hot air enters from the main pipe, it will be evenly distributed to the air supply plate 51 through each branch pipe, and then sprayed on the surface of the strip through the nozzle 53.

[0058] In this embodiment, the adsorption roller 54 includes a rotating shaft rotatably arranged on the air supply plate 51, and the outer portion of the rotating shaft is sleeved with absorbent cotton 541.

[0059] A set of adsorption rollers 54 are located at the upper and lower sides of the conveying hole, and the absorbent cotton is in a ring shape.

[0060] The adsorption roller 54 is composed of a rotating shaft and a water-absorbing cotton 541. The rotating shaft is rotatably arranged on the air supply plate 51, and is used to drive the rotation of the water-absorbing cotton 541. The water-absorbing cotton 541 is in a ring shape, tightly sleeved on the rotating shaft, and has good water absorption performance. When the strip steel passes through, the water-absorbing cotton 541 can absorb the residual water on the surface of the strip steel.

[0061] A set of adsorption rollers 54 are located on the upper and lower sides of the conveying hole, corresponding to the upper and lower surfaces of the strip steel respectively. Such a layout can ensure that when the strip steel passes through the conveying hole, its upper and lower surfaces can be effectively adsorbed by the absorbent cotton 541 to remove residual moisture.

[0062] It should be noted that in this embodiment, a plurality of guide rollers 6 for guiding the conveying of the steel strip are rotatably arranged inside the cleaning tank 2, and a conveying pipe for supplying cleaning water and a drain valve for discharging cleaning water are arranged on the cleaning tank 2.

[0063] The guide roller 6 is used to guide the conveying direction of the steel strip to ensure that the steel strip can move steadily and smoothly in the cleaning tank 2. The rotation design of the guide roller 6 can reduce the friction between the steel strip and the inner wall of the cleaning tank 2, reduce the wear of the steel strip, and also contribute to the uniform distribution of the cleaning liquid and the thorough cleaning of the surface of the steel strip.

[0064] Washing water supply and drainage:

[0065] A delivery pipe for supplying cleaning water is provided on the cleaning tank 2. The delivery pipe is responsible for delivering cleaning liquid such as clean water, cleaning agent solution, etc. into the cleaning tank 2 to provide sufficient cleaning liquid for cleaning the strip steel. The drain valve is used to control the discharge of the cleaning liquid in the cleaning tank 2 to ensure that when the cleaning liquid needs to be replaced or discharged, it can be operated conveniently and quickly.
