Description

TECHNICAL FIELD

[0001] The utility model relates to metal surface treatment technical field especially is related to a drying device for metal surface pickling treatment. BACKGROUND

[0002] In the field of metal processing and manufacturing, metal surface treatment is a crucial process that directly affects the quality, performance, and service life of metal products. Among them, pickling, as one of the key steps in metal surface treatment, plays an irreplaceable role.

[0003] Pickling mainly uses acidic solution to chemically treat the metal surface to remove impurities such as oxidation scale, rust products, and oil stains. During the processing, storage, and transportation of metals, the surface is prone to chemical reactions with oxygen and moisture in the air, forming an oxide scale. This oxide scale not only affects the appearance quality of the metal but also reduces the bonding force between the metal and other materials, affecting the subsequent coating, electroplating, and other process effects. Through pickling treatment, these impurities can be effectively removed, and the metal surface can meet certain cleanliness and roughness requirements, providing good surface conditions for subsequent processing procedures.

[0004] The existing CN202421038772.X metal surface efficient pickling device has certain progressiveness. However, after the metal surface is treated by pickling, a large amount of acidic solution and moisture will remain on the surface. If drying treatment is not performed in a timely manner, these residual liquids will not only corrode the metal surface, causing metal products to rust and other problems, but also affect the implementation effect of subsequent processes. For example, in the coating process, residual moisture and acidic substances may chemically react with the paint, causing the coating to bubble, peel, and other defects, severely affecting the quality and protective performance of the coating.

[0005] Currently, although there are some drying devices for metal surface pickling treatment on the market, these devices have many inconveniences in actual use. Some drying devices have unreasonable structural design, resulting in low drying efficiency and the need for a long drying time to remove moisture from the metal surface. SUMMARY

[0006] To solve the above technical problems, the purpose of the utility model is to provide a drying device for metal surface pickling treatment, which improves the drying efficiency after pickling.

[0007] To achieve the above purpose, the utility model provides the following technical scheme:

[0008] The utility model provides a kind of drying device for metal surface pickling treatment, including base, the base is provided with translation component by fixing frame, the movable part of translation component is fixedly connected with lifting assembly, the bottom movable part of lifting assembly is fixedly connected with rotation drive assembly, the output shaft of rotation drive assembly towards below is fixedly connected with the clamping assembly for clamping metal piece;The base is provided with cleaning tank and drying tank, the cleaning tank is filled with cleaning fluid, the drying tank is provided with drying assembly, improves drying efficiency.

[0009] Preferably, the drying assembly includes a gas cavity provided on the outer wall of the drying tank, a plurality of gas outlets are formed on the inner wall of the drying tank, the gas outlets are in communication with the gas cavity, and a hot air blower is connected to the outer wall of the gas cavity, thereby improving the drying efficiency.

[0010] Preferably, the inner wall of the drying tank is bonded with moisture-absorbing bristles to absorb moisture and improve the drying efficiency.

[0011] Preferably, the bottom of the cleaning tank is connected with a drain pipe, and a control valve is fixedly arranged on the drain pipe to drain the turbid cleaning fluid and add new cleaning fluid.

[0012] Preferably, the translation component is an electric sliding table, the lifting assembly is a lifting cylinder, the rotation drive assembly is a reversible motor, and the clamping assembly is an electric clamping jaw, which is mature in technology and convenient to control.

[0013] Preferably, the cleaning fluid is water, which is low in cost and easy to handle.

[0014] The utility model has the following beneficial effects:

[0015] Optimizing the drying structure to improve the drying efficiency: in the drying device, the drying assembly includes a gas cavity provided on the outer wall of the drying tank, a plurality of gas outlets are formed on the inner wall of the drying tank, and the gas outlets are in communication with the gas cavity, and a hot air blower is connected to the outer wall of the gas cavity. This design allows the hot air generated by the hot air blower to be evenly distributed to each gas outlet through the gas cavity, and then blown to the metal pieces in the drying tank from the gas outlets. Compared with the traditional single air outlet design, the multiple gas outlets can realize multi-angle and omnidirectional coverage of hot air, ensuring that each part of the metal piece surface can quickly contact the hot air, thereby accelerating the evaporation of moisture and greatly improving the drying efficiency of the metal piece after pickling.

[0016] The dry effect is improved by the moisture absorption brush: the moisture absorption brush is adhered to the inner wall of the drying groove, and the moisture absorption brush can be in full contact with the surface of the metal piece during the drying process of the metal piece. On the one hand, the moisture absorption brush itself has a certain moisture absorption, and can directly absorb part of the water on the surface of the metal piece, reducing the free water content on the surface of the metal piece; on the other hand, the presence of the moisture absorption brush can increase the air flow resistance around the metal piece, so that the hot air stays on the surface of the metal piece for a longer time, further enhancing the heat exchange between the hot air and the metal piece, and promoting the water to be taken away more quickly, thereby improving the drying efficiency of the metal piece after pickling as a whole.

[0017] The translation, lifting and rotating assemblies cooperate to improve the drying efficiency: the movable part of the translation assembly is fixedly connected with the lifting assembly, the bottom movable part of the lifting assembly is fixedly connected with the rotating driving assembly, and the output shaft of the rotating driving assembly towards the bottom is fixedly connected with the clamping assembly. In actual use, the translation assembly can accurately move the clamping assembly clamping the metal piece from the cleaning tank to above the drying tank, the lifting assembly can adjust the depth of the metal piece entering the drying tank, so that the metal piece is in the best drying position, and the rotating driving assembly can rotate the metal piece during the drying process. This kind of multi-component cooperative working mode can make the metal piece in the drying tank be more fully and uniformly dried, avoiding the problem of uneven drying caused by the fact that part of the metal piece cannot fully contact the hot air, and effectively improving the drying efficiency of the metal piece after pickling.

DETAILED DESCRIPTION

[0022] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] The first embodiment

[0024] As shown in Figure 1 A drying device for metal surface pickling treatment, comprising a base 1, a translation assembly 301 is arranged on the base 1 through a fixing frame 2, a movable part of the translation assembly 301 is fixedly connected with a lifting assembly 302, a bottom movable part of the lifting assembly 302 is fixedly connected with a rotating drive assembly 303, and a clamping assembly 304 for clamping metal pieces is fixedly connected with an output shaft of the rotating drive assembly 303 towards the bottom; a cleaning tank 5 and a drying tank 6 are arranged on the base 1, the cleaning tank 5 is filled with cleaning liquid, and the drying tank 6 is provided with a drying assembly, thereby improving the drying efficiency.

[0025] As shown in Figure 1As shown, first, the metal piece to be processed is clamped and fixed by the clamping assembly 304. The translation assembly 301 starts to work, and the movable part drives the lifting assembly 302 fixedly connected thereto and the rotating drive assembly 303, the clamping assembly 304 and the metal piece below to move together, so as to accurately move the metal piece above the cleaning tank 5. Subsequently, the lifting assembly 302 starts to work, and the bottom movable part of the lifting assembly 302 descends, so that the clamping assembly 304 with the metal piece is immersed in the cleaning liquid in the cleaning tank 5, and the metal piece after pickling is cleaned to remove the impurities such as residual acid liquid on the surface. After cleaning, the bottom movable part of the lifting assembly 302 rises, and the clamping assembly 304 and the metal piece are taken out of the cleaning liquid. The translation assembly 301 is started again, and the movable part drives the lifting assembly 302, the rotating drive assembly 303, the clamping assembly 304 and the metal piece to move horizontally, so as to be transferred from above the cleaning tank 5 to above the drying tank 6, and to prepare for the drying stage. Subsequently, the lifting assembly 302 continues to work, and the clamping assembly 304 and the metal piece are lowered to a suitable position in the drying tank 6. The drying assembly starts to work, and the hot air generated by the hot air machine 603 in the drying assembly enters the air cavity 601 outside the drying tank 6, and then is uniformly blown to the metal piece in the drying tank 6 through a plurality of air outlets 602 in communication with the air cavity 601. At the same time, the rotating drive assembly 303 is started, and the output shaft drives the clamping assembly 304 and the metal piece to rotate. The rotation enables each part of the metal piece surface to be in contact with the hot air more fully, and the hot air can blow the metal piece surface in all directions to accelerate the evaporation of the water on the metal piece surface. Moreover, the hygroscopic bristles 604 bonded to the inner wall of the drying tank 6 are in full contact with the rotating metal piece surface, and the hygroscopic bristles 604 can directly absorb part of the water on the metal piece surface, and can increase the flow resistance of the air around the metal piece, prolong the residence time of the hot air on the metal piece surface, and enhance the heat exchange between the hot air and the metal piece, thereby greatly improving the drying efficiency of the metal piece after pickling. Finally, the cleaning tank 5 is connected with a liquid discharge pipe 501, and the control valve 502 is fixedly arranged on the liquid discharge pipe 501. After the cleaning tank 5 completes the cleaning task of the metal piece, the control valve 502 is opened, so that the cleaning liquid in the cleaning tank 5 is discharged through the liquid discharge pipe 501, so as to perform subsequent cleaning liquid replacement or other processing operations.

[0026] As Figure 1As shown, in the drying assembly, the air cavity 601 is arranged outside the drying groove 6, a plurality of air outlets 602 are arranged on the inner wall of the drying groove 6 and are communicated with the air cavity 601, and the outer wall of the air cavity 601 is communicated with the hot air fan 603. When the hot air fan 603 is started, the hot air fan 603 generates hot air, and the hot air enters the air cavity 601. Since the air cavity 601 is communicated with the plurality of air outlets 602, the hot air is evenly distributed to each air outlet 602 and blown from the air outlet 602 to the inside of the drying groove 6. The design of the plurality of air outlets 602 enables the hot air to cover the surface of the metal piece at multiple angles and in all directions, ensuring that each part of the surface of the metal piece can quickly contact the hot air, accelerating the evaporation of the moisture on the surface of the metal piece, and thereby improving the drying efficiency.

[0027] As shown in the first embodiment, Figure 1 As shown, the cleaning tank 5 is connected with a drain pipe 501, and the drain pipe 501 is fixedly provided with a control valve 502. After the cleaning tank 5 is used for a period of time, the water (cleaning liquid) in the inside will become turbid due to impurities accumulation. At this time, the turbid water in the cleaning tank 5 can be drained through the drain pipe 501 by opening the control valve 502. After the turbid water is drained, new cleaning water can be added to the cleaning tank 5 to ensure the cleaning effect of the metal piece.

[0028] As shown in the first embodiment, Figure 1 As shown, the translation assembly 301 is an electric sliding table, the lifting assembly 302 is a lifting electric cylinder, the rotation driving assembly 303 is a reversible motor, and the clamping assembly 304 is an electric clamping jaw. The translation assembly 301 is an electric sliding table, which is mature in technology and can realize stable and accurate horizontal movement, facilitating the movement of the part clamping the metal piece from above the cleaning tank 5 to above the drying groove 6; the lifting assembly 302 is a lifting electric cylinder, which can conveniently control the lifting action and realize accurate movement in the vertical direction, accurately putting or taking the metal piece into or out of the cleaning tank 5 and the drying groove 6; the rotation driving assembly 303 is a reversible motor, which can drive the clamping assembly 304 to rotate forward or reverse with the metal piece, so that the metal piece can be more fully contacted with the hot air during the drying process, improving the drying efficiency; the clamping assembly 304 is an electric clamping jaw, which is easy to operate and can stably clamp the metal piece, and is convenient to control, and the clamping force can be adjusted according to actual needs.

[0029] As shown in the first embodiment, Figure 1 As shown, the cleaning liquid is water, which has low cost, wide source, and relatively simple treatment after use, does not cause great burden to the environment, and can meet the cleaning demand of the impurities on the surface of the metal piece after pickling.

[0030] Second embodiment

[0031] As shown in the first embodiment, Figure 2As shown, the inner wall of the drying groove 6 is bonded with the hygroscopic bristles 604 to carry out hygroscopicity and improve the drying efficiency. In the drying process, the hygroscopic bristles 604 are in full contact with the surface of the metal piece. On the one hand, the hygroscopic bristles 604 itself has a certain hygroscopicity, which can directly adsorb part of the moisture remaining on the surface of the metal piece, reducing the free water content on the surface of the metal piece; on the other hand, the presence of the hygroscopic bristles 604 increases the flow resistance of the air around the metal piece, so that the hot air stays on the surface of the metal piece for a longer time, further enhancing the heat exchange between the hot air and the metal piece, promoting the moisture to be taken away faster, thereby improving the drying efficiency.

[0032] The above is only a specific embodiment of the present application, but the technical features of the present application are not limited to this. Any simple change, equivalent replacement or modification made on the basis of the present application to solve the same technical problem and achieve the same technical effect is also covered by the protection scope of the present application.
