Description

Technical Field

[0001] This utility model relates to the field of electroplating production line technology, and in particular to an online cleaning device for oxide scale in the high-frequency heat diffusion zone of a continuous electroplating production line. Background Technology

[0002] Electroplating is a common surface treatment technology widely used in the metal products industry. During electroplating, a protective metallic coating, such as zinc or nickel, is formed on the surface of steel wire. This coating effectively prevents the steel wire from being corroded by environmental factors such as moisture, acids, and alkalis during use, thus extending its service life.

[0003] During long-term operation of a continuous electroplating production line, a large amount of oxide scale waste is generated in the high-frequency heat diffusion zone due to high temperature and friction. If the oxide scale is not cleaned in time, it will cause uneven heating, thereby affecting the diffusion effect and ultimately causing the product performance to fail to meet requirements. At the same time, the accumulated oxide scale will enter the working holes of the heat diffusion zone, causing blockage.

[0004] The existing production line design requires stopping production and then purging with compressed air. If purging is performed directly during production, a large amount of air entering the heating holes could cause a fire, posing a serious safety hazard. Therefore, it is necessary to stop the machine for cleaning. However, stopping and restarting each production line results in scrap and lost production time, leading to increased costs. Utility Model Content

[0005] The main purpose of this utility model is to provide an online cleaning device for oxide scale in the high-frequency heat diffusion zone of a continuous electroplating production line. The dust collection hood is matched with the reserved opening of the steel wire conveying trough. During the steel wire conveying process, the dust collection hood can be connected to the negative pressure dust collection equipment in the workshop. When the negative pressure dust collection equipment is working, the dust collection hood is in a negative pressure state, so that the oxide scale waste in the steel wire conveying trough can be sucked up and cleaned through the dust suction pipe and dust conveying pipe 7 without the need to stop the machine.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An online cleaning device for oxide scale in the high-frequency thermal diffusion zone of a continuous electroplating production line includes a dust collection hood with an opening at the bottom. A base plate is fixed to the opening at the bottom of the dust collection hood. A dust suction assembly is installed inside the dust collection hood. The dust suction assembly includes a crossbeam. Several dust conveying pipes are arranged along the length of the crossbeam. Several dust suction pipes are connected to the bottom of the dust conveying pipes. The bottom end of the dust suction pipes penetrates the base plate and is located outside the dust collection hood.

[0008] Furthermore, the bottom of the base plate is fixed with several limiting frames that match the shape of the dust conveying pipe, the dust conveying pipe is inserted into the limiting frames and the suction pipe passes through the limiting frames.

[0009] Furthermore, the crossbeam has a U-shaped cross-section, and the dust conveying pipe has an opening at the top that extends through the crossbeam.

[0010] Furthermore, the bottom of the dust conveying pipe has a sealing plate, and the tops of several dust suction pipes penetrate the sealing plate and are connected to the dust conveying pipe.

[0011] Furthermore, through holes are provided on opposite sides of the dust collection hood, and the crossbeam is fixed inside the dust collection hood by fixing components and through holes.

[0012] Furthermore, the fixing assembly includes a crossbar and several positioning rods fixed to the crossbar. One end of each positioning rod passes through a through hole on one side of the dust collection hood, the crossbeam, and a through hole on the other side of the dust collection hood, and is fixed to the dust collection hood by bolts.

[0013] Furthermore, a conveying pipe is connected to the dust collection hood.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The dust collection hood of this utility model is matched with the reserved opening of the steel wire conveying trough. During the steel wire conveying process, the dust collection hood can be connected to the negative pressure dust collection equipment in the workshop. When the negative pressure dust collection equipment is working, the dust collection hood is in a negative pressure state, so that the oxide scale waste in the steel wire conveying trough can be sucked up and cleaned through the dust suction pipe and dust conveying pipe without the need to stop the machine.

[0016] The suction pipe of this invention has a smaller cross-sectional area than the conveying pipe, thus the suction pipe has a stronger adsorption force, improving its ability to absorb oxide scale waste. Furthermore, since there are several suction pipes on a single conveying pipe, even if one suction pipe is blocked, the conveying pipe will not be completely unable to adsorb oxide scale waste.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1-7 As shown, an online cleaning device for oxide scale in the high-frequency heat diffusion zone of a continuous electroplating production line includes a dust collection hood 1 with an opening at the bottom. A base plate 2 is fixed to the opening at the bottom of the dust collection hood 1. A dust collection assembly is installed inside the dust collection hood 1. The dust collection assembly includes a crossbeam 6. Several dust conveying pipes 7 are arranged along the length of the crossbeam 6. Several dust collection pipes 5 are connected to the bottom of the dust conveying pipes 7. The dust collection pipes 5 are made of a high-temperature resistant material, such as mica board. The bottom end of the dust collection pipe 5 passes through the base plate 2 and is located outside the dust collection hood 1.

[0027] In this embodiment, such as Figure 1 and Figure 6 As shown, a conveying pipe 101 is connected to the dust collection hood 1. The conveying pipe 101 is connected to the negative pressure dust collection equipment in the workshop. The dust collection hood 1 should cover the conveying trough of the steel wire and ensure that the suction pipe 5 is inserted into the conveying trough of the steel wire. When the negative pressure dust collection equipment in the workshop is working, the dust collection hood 1 will be in a negative pressure state, which will cause the suction pipe 5 to generate suction force to suck up the oxide scale waste in the conveying trough of the steel wire. The oxide scale waste will then pass through the suction pipe 5, the dust conveying pipe 7, and the conveying pipe 101 in sequence into the negative pressure dust collection equipment in the workshop. During this process, since the cross-sectional area of ​​the suction pipe 5 is smaller than that of the dust conveying pipe 7, the suction force of the suction pipe 5 is stronger, which improves its ability to absorb oxide scale waste. In addition, there are several suction pipes 5 on a single dust conveying pipe 7, so even if a certain suction pipe 5 is blocked, it will not cause the dust conveying pipe 7 to be completely unable to absorb oxide scale waste.

[0028] Among them, such as Figure 1 and Figure 5 As shown, several limiting frames 4 that match the shape of the dust conveying pipe 7 are fixed at the bottom of the base plate 2. The dust conveying pipe 7 is inserted into the limiting frame 4 and the suction pipe 5 passes through the limiting frame 4. The limiting frame 4 is in full contact with the suction pipe 5, which can limit the dust conveying pipe 7 and determine the position of the suction pipe 5. In addition, while limiting the dust conveying pipe 7, the limiting frame 4 can also protect the dust conveying pipe 7, prevent the dust conveying pipe 7 from being deformed due to collision, and ensure that its internal channel is unobstructed.

[0029] Among them, such as Figure 4 As shown, the cross-section of the beam 6 is U-shaped, and the top of the dust conveying pipe 7 has an opening that runs through the beam 6. There are no obstacles above the beam 6, making it easier for the airflow to flow and thus facilitating the adsorption of oxide scale waste. Furthermore, the bottom of the dust conveying pipe 7 has a sealing plate 8, and the tops of several suction pipes 5 pass through the sealing plate 8 and are connected to the dust conveying pipe 7. Therefore, the oxide scale waste in the wire conveying trough can only enter the dust conveying pipe 7 through the suction pipes 5, making the adsorption of gas more concentrated and further improving the suction power.

[0030] Among them, such as Figure 1 , Figure 2 and Figure 7 As shown, the dust collection hood 1 has through holes 102 on opposite sides, and also includes a fixing component 3. The fixing component 3 includes a crossbar 301 and several positioning rods 302 fixed to the crossbar 301. One end of the positioning rod 302 passes through the through hole 102 on one side of the dust collection hood 1, the crossbeam 6, and the through hole 102 on the other side of the dust collection hood 1, as shown. Figure 7 As shown, the end of the positioning rod 302 has a threaded hole. Therefore, personnel can screw the bolt into this threaded hole to fix the positioning rod 302. Since the limiting frame 4 can limit the dust conveying pipe 7, the position of the dust collection component can be fixed. During disassembly, the positioning rod 302 can be pulled out by simply unscrewing the bolt out of the threaded hole. After the base plate 2 is disassembled, the dust collection component can be taken out from the dust collection hood 1.

[0031] The working principle is as follows: First, the dust collection hood 1 is placed over the reserved opening of the steel wire conveying trough, ensuring that the suction pipes 5 are inserted into the steel wire conveying trough and that each suction pipe 5 is aligned with the gap in the steel wire. Then, the conveying pipe 101 of the dust collection hood 1 is connected to the negative pressure dust collection equipment in the workshop. Next, the negative pressure dust collection equipment in the workshop operates, thereby creating a negative pressure state inside the dust collection hood 1. Since the suction pipes 5 are connected to the dust collection hood 1 through the dust conveying pipe 7, the suction pipes 5 generate suction force, sucking up the oxide scale waste in the steel wire conveying trough. The oxide scale waste is then sequentially passed through the suction pipes 5, the dust conveying pipe 7, and the conveying pipe 101 into the negative pressure dust collection equipment in the workshop. During this process, because the cross-sectional area of ​​the suction pipe 5 is smaller than that of the dust conveying pipe 7, the suction force of the suction pipe 5 is stronger, improving its ability to absorb oxide scale waste. Furthermore, since there are several suction pipes 5 on a single dust conveying pipe 7, even if one suction pipe 5 is blocked, it will not cause the dust conveying pipe 7 to be completely unable to absorb oxide scale waste.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
