Abstract
Description
Technical Field
[0001] This application relates to the field of metal galvanizing technology, and in particular to a galvanizing aid tank for iron wire. Background Technology
[0002] To improve the corrosion resistance of metal surfaces, after washing the workpiece, it is usually placed in a flux bath and coated with flux to form a protective salt film on the metal surface, which prevents oxidation and improves the adhesion of the zinc coating, thereby enhancing the corrosion resistance of the metal workpiece.
[0003] In actual use, the existing fluxing tanks become increasingly turbid over time due to the mixing of impurities such as iron filings and oil on the surface of the wires, which affects the performance of the fluxing solution. When replacing the fluxing solution, the machine needs to be stopped to drain the old fluxing solution and replenish it with the new fluxing solution. At the same time, monitoring the turbidity of the fluxing solution relies on manual sampling and testing. The whole process is time-consuming and labor-intensive, and the accuracy and production efficiency are both low.
[0004] Therefore, this application provides a galvanizing bath for galvanized iron wire. Utility Model Content
[0005] To address the shortcomings of existing technologies, this application provides a galvanized iron wire fluxing tank, which overcomes the deficiencies of existing technologies. It aims to solve the problem that in actual use, the fluxing solution gradually becomes turbid due to the mixing of impurities such as iron filings and oil stains on the surface of the iron wire during long-term use, which affects its performance. When replacing the fluxing solution, it is necessary to stop the machine to drain the old fluxing solution and replenish it with new fluxing solution. At the same time, the turbidity monitoring of the fluxing solution relies on manual sampling and testing, which is time-consuming, labor-intensive, and has low accuracy and production efficiency.
[0006] To achieve the above objectives, this application provides the following technical solution: a galvanized iron wire fluxing tank, comprising a tank body, two sets of supports fixedly installed at the top of the tank body, each set of supports being rotatably connected to a guide shaft at its top, two sets of downward pressure shafts rotatably connected inside the tank body, a turbidity sensor fixedly installed on the inner wall of the tank body, a fluxing solution storage tank placed on one side of the tank body, a pump body first installed above the fluxing solution storage tank, a recovery pipe installed between the extraction end of the pump body first and the bottom of the tank body, a mounting frame fixedly installed at the top of the tank body, a metering pump fixedly installed at the top of the mounting frame, a suction pipe installed between the extraction end of the metering pump and the mounting frame, a delivery pipe installed between the discharge end of the metering pump and the top of the tank body, and a controller fixedly installed on one side of the mounting frame, the controller being electrically connected to the pump body first, the metering pump, and the turbidity sensor.
[0007] By adopting the above technical solution, the turbidity of the flux in the tank is monitored in real time by a turbidity sensor, and the data is fed back to the controller. Clean flux is stored in a flux storage tank. When the turbidity of the flux in the tank exceeds the preset value, the controller automatically starts pump one to extract the turbid flux through the recovery pipe. At the same time, the controller automatically controls the metering pump to extract the clean flux stored in the flux storage tank and reinject it into the tank through the delivery pipe. Pump one and the metering pump can work synchronously, so there is no need to stop the machine when changing the flux in the tank, which improves production efficiency. Moreover, the automatic detection by the turbidity sensor avoids the error of manual sampling and improves the accuracy of flux turbidity detection.
[0008] As a preferred technical solution of this application, a motor frame is fixedly installed on one side of the flux storage tank, a motor is fixedly installed in the middle of the motor frame, a stirring mechanism is provided inside the flux storage tank, the stirring mechanism includes a stirring shaft, the stirring shaft is rotatably connected to the inside of the tank, and one end of the stirring shaft is connected to the output end of the motor, and two sets of spiral stirring blades are fixedly installed on the outer surface of the stirring shaft, and the two sets of spiral stirring blades are reverse threads.
[0009] By adopting the above technical solution, the stirring shaft is driven by a motor to rotate, and the two sets of spiral stirring blades with opposite threads on its outer surface rotate synchronously. This causes the flux to generate a composite flow in the axial and radial directions when the two sets of spiral stirring blades rotate. The two sets of spiral stirring blades have opposite threads, which enhances the mixing effect and helps to prevent zinc salt crystallization and precipitation in the flux, thus ensuring the uniformity of the flux entering the tank.
[0010] As a preferred technical solution of this application, a filter box is fixedly installed on the top of the flux storage tank, and the filter box is connected to the flux storage tank. A pump body is fixedly installed on the top of the filter box, and the discharge end of the pump body is connected to the filter box. Several sets of limiting rings are fixedly installed inside the filter box. From top to bottom, a coarse filter screen, a medium filter screen, and a fine filter screen are arranged inside the filter box. The coarse filter screen, the medium filter screen, and the fine filter screen are all snapped above the corresponding limiting rings.
[0011] By adopting the above technical solution, after the fluxing solution enters the filter box, it is filtered through a coarse filter to intercept large particles such as iron filings, a medium filter to remove oil stains, and a fine filter to filter out tiny suspended solids. The turbid fluxing solution is filtered step by step and then discharged into the fluxing solution storage tank, thereby achieving the purpose of recycling and reusing the fluxing solution in the tank.
[0012] As a preferred embodiment of this application, two sets of fixing plates are fixedly installed on the outer wall of the filter box, an outer cover is installed on the front surface of the filter box, and mounting plates are fixedly installed on both sides of the outer cover. Bolts are installed at the connection between the fixing plates and the mounting plates.
[0013] By adopting the above technical solution, the fixing page and the mounting page are connected by bolts, and the outer cover is fixed to the surface of the filter box. The outer cover can be easily disassembled by removing the bolts, which facilitates the cleaning or replacement of the coarse filter screen, medium filter screen and fine filter screen.
[0014] As a preferred technical solution of this application, a liquid level sensor is fixedly installed on the inner wall of the tank, the liquid level sensor is located above the turbidity sensor, and the liquid level sensor is electrically connected to the controller.
[0015] By adopting the above technical solution, the liquid level of the flux in the tank is monitored in real time by a liquid level sensor, which makes it easier for the controller to determine whether to replenish the liquid based on the liquid level, thereby improving the stability of the liquid level of the flux in the tank.
[0016] As a preferred technical solution of this application, the stirring shaft is provided with a number of guide holes inside.
[0017] By adopting the above technical solution, the guide hole and the reverse threaded spiral stirring blade work together during stirring, allowing the flux to be exchanged laterally in the tank, further enhancing the mixing effect of the flux.
[0018] As a preferred technical solution of this application, the outer surfaces of both the guide shaft and the pressing shaft are provided with several sets of guide grooves.
[0019] By adopting the above technical solution, the iron wire is transmitted through two sets of guide shafts and pressed down into the tank by two sets of pressing shafts to fully contact the plating solution. During the transmission process, it moves along the corresponding guide groove, which improves the guidance of the iron wire during the transmission process.
[0020] As a preferred technical solution of this application, a sealing ring is installed at the connection between the outer cover and the filter box.
[0021] By adopting the above technical solution, the gap between the outer cover and the filter box is reduced by using a sealing ring, thereby improving the sealing performance of the filter box.
[0022] The beneficial effects of this application are:
[0023] 1. The turbidity of the flux in the tank is monitored in real time by a turbidity sensor, and the data is fed back to the controller. Clean flux is stored in a flux storage tank. When the turbidity of the flux in the tank exceeds the preset value, the controller automatically starts pump one to extract the turbid flux through the recovery pipe. At the same time, the controller automatically controls the metering pump to extract the clean flux stored in the flux storage tank and reinject it into the tank through the delivery pipe. Pump one and the metering pump can work synchronously, so there is no need to stop the machine when changing the flux in the tank, which improves production efficiency. Moreover, the automatic detection by the turbidity sensor avoids the error of manual sampling and improves the accuracy of flux turbidity detection.
[0024] 2. The stirring shaft is driven by a motor to rotate, and the two sets of spiral stirring blades with opposite threads on its outer surface rotate synchronously. This causes the flux to generate a composite flow in the axial and radial directions as the two sets of spiral stirring blades rotate. The two sets of spiral stirring blades have opposite threads, which enhances the mixing effect and helps to prevent zinc salt crystallization and precipitation in the flux, ensuring the uniformity of the flux entering the tank.

Two sets of downward pressure shafts 4 are rotatably connected inside the tank body 1. A turbidity sensor 5 is fixedly installed on the inner wall of the tank body 1. A flux storage tank 6 is placed on one side of the tank body 1. A pump body 7 is installed above the flux storage tank 6. A recovery pipe 8 is installed between the extraction end of the pump body 7 and the bottom of the tank body 1. A mounting frame 9 is fixedly installed at the top of the tank body 1. A metering pump 10 is fixedly installed at the top of the mounting frame 9. A suction pipe 11 is installed between the extraction end of the metering pump 10 and the mounting frame 9. The discharge end of the metering pump 10 is connected to the top of the tank body 1. A delivery pipe 12 is installed in the middle, and a controller 14 is fixedly installed on one side of the mounting frame 9. The controller 14 is electrically connected to the pump body 7, the metering pump 10, and the turbidity sensor 5. A filter box 18 is fixedly installed on the top of the flux storage tank 6 and is connected to the flux storage tank 6. The pump body 7 is fixedly installed on the top of the filter box 18 and the discharge end of the pump body 7 is connected to the filter box 18. Several sets of limiting rings 19 are fixedly installed inside the filter box 18. From top to bottom, the filter box 18 is provided with a coarse filter screen 20, a medium filter screen 21, and a fine filter screen 22. The coarse filter screen 20, the medium filter screen 21, and the fine filter screen 22 are all snapped above the corresponding limiting rings 19.
[0032] The turbidity of the flux in tank 1 is monitored in real time by a turbidity sensor 5 (model E+HTurbimaxCUS52D) and the data is fed back to the controller 14. Clean flux is stored in the flux storage tank 6. When the turbidity of the flux in tank 1 exceeds a preset value, the controller 14 automatically starts pump 7 to extract the turbid flux through the recovery pipe 8. Simultaneously, the controller 14 automatically controls the metering pump 10 to extract the clean flux stored in the flux storage tank 6 and reinject it into tank 1 through the delivery pipe 12. When the pump body 7 and the metering pump 10 work synchronously, the machine does not need to be stopped when changing the flux in the tank 1, which improves production efficiency. Moreover, the turbidity sensor 5 automatically detects the turbidity, avoiding errors from manual sampling and improving the accuracy of flux turbidity detection. After the flux enters the filter box 18, it passes through the coarse filter 20 to intercept large particles such as iron filings, the medium filter 21 to remove oil stains, and the fine filter 22 to filter out small suspended matter. The turbid flux is filtered step by step and then discharged into the flux storage tank 6, thereby achieving the purpose of recycling and reusing the flux in the tank 1.
[0033] Reference Figures 2-4 A motor frame 15 is fixedly installed on one side of the flux storage tank 6, and a motor 16 is fixedly installed in the middle of the motor frame 15. A stirring mechanism 17 is provided inside the flux storage tank 6. The stirring mechanism 17 includes a stirring shaft 1701, which is rotatably connected to the inside of the tank 1. One end of the stirring shaft 1701 is connected to the output end of the motor 16. Two sets of spiral stirring blades 1702 are fixedly installed on the outer surface of the stirring shaft 1701, and the two sets of spiral stirring blades 1702 have reverse threads. Two sets of fixing blades 23 are fixedly installed on the outer wall of the filter box 18. An outer cover 25 is installed on the front surface of the filter box 18. Mounting blades 26 are fixedly installed on both sides of the outer cover 25. Bolts 27 are installed at the connection between the fixing blades 23 and the mounting blades 26.
[0034] The stirring shaft 1701 is driven to rotate by the motor 16. The two sets of spiral stirring blades 1702 with opposite threads on its outer surface rotate synchronously, so that the fluxing solution generates a composite flow of axial and radial directions when the two sets of spiral stirring blades 1702 rotate. The two sets of spiral stirring blades 1702 have opposite threads, which enhances the mixing effect and helps to prevent zinc salt crystallization and precipitation in the fluxing agent, ensuring the uniformity of the fluxing agent entering the tank 1. The fixing page 23 and the mounting page 26 are connected by bolts 27 to fix the outer cover 25 to the surface of the filter box 18. The outer cover 25 can be easily removed by removing the bolts 27, so as to facilitate the cleaning or replacement of the coarse filter screen 20, the medium filter screen 21, and the fine filter screen 22.
[0035] Reference Figures 1-3A liquid level sensor 13 is fixedly installed on the inner wall of the tank 1. The liquid level sensor 13 is located above the turbidity sensor 5 and is electrically connected to the controller 14. Several sets of guide grooves 28 are opened on the outer surface of the guide shaft 3 and the pressing shaft 4. The liquid level sensor 13 monitors the liquid level of the flux in the tank 1 in real time, which makes it easier for the controller 14 to determine whether to replenish the liquid based on the liquid level, thus improving the stability of the liquid level of the flux in the tank 1. The iron wire is transmitted through two sets of guide shafts 3 and pressed down in the tank 1 by two sets of pressing shafts 4 to make full contact with the flux. During the transmission process, it moves along the corresponding guide grooves 28, which improves the guidance of the iron wire during the transmission process.
[0036] Reference Figures 2-4 The stirring shaft 1701 has several sets of guide holes 1703 inside; a sealing ring is installed at the connection between the outer cover 25 and the filter box 18; the guide holes 1703 and the reverse threaded spiral stirring blades 1702 work together during stirring to allow the flux to be exchanged laterally in the tank 1, further enhancing the mixing effect of the flux; the sealing ring reduces the gap between the outer cover 25 and the filter box 18, improving the sealing performance of the filter box 18.
[0037] Working Principle: The turbidity of the flux in tank 1 is monitored in real time by the turbidity sensor 5, and the data is fed back to the controller 14. Clean flux is stored in the flux storage tank 6. When the turbidity of the flux in tank 1 exceeds the preset value, the controller 14 automatically starts the pump 7 to extract the turbid flux through the recovery pipe 8. At the same time, the controller 14 automatically controls the metering pump 10 to extract the clean flux stored in the flux storage tank 6 and reinject it into tank 1 through the delivery pipe 12. The pump 7 and the metering pump 10 can work synchronously to further improve the turbidity of the flux in tank 1. No machine shutdown is required when changing the flux, which improves production efficiency. The turbidity sensor 5 automatically detects the turbidity, avoiding errors from manual sampling and improving the accuracy of flux turbidity detection. The motor 16 drives the stirring shaft 1701 to rotate, and the two sets of reverse-threaded spiral stirring blades 1702 on its outer surface rotate synchronously. This causes the flux to generate a composite axial and radial flow as the two sets of spiral stirring blades 1702 rotate. The two sets of spiral stirring blades 1702 have reverse threads, which enhances the mixing effect and helps prevent zinc salt crystallization and precipitation in the flux, ensuring the uniformity of the flux entering the tank 1.
[0038] The fluxing solution enters the filter box 18 and passes through a coarse filter 20 to intercept large particles such as iron filings, a medium filter 21 to remove oil stains, and a fine filter 22 to filter out tiny suspended solids. The turbid fluxing solution is filtered step by step and then discharged into the fluxing solution storage tank 6, thereby achieving the purpose of recycling and reusing the fluxing solution in the tank 1. The fixing page 23 and the mounting page 26 are connected by bolts 27 to fix the outer cover 25 to the surface of the filter box 18. The outer cover 25 can be easily removed by removing the bolts 27, which makes it easy to clean or replace the coarse filter 20, the medium filter 21, and the fine filter 22.
[0039] Meanwhile, the liquid level sensor 13 monitors the liquid level of the flux in the tank 1 in real time, which makes it easier for the controller 14 to determine whether to replenish the liquid based on the liquid level, thus improving the stability of the liquid level of the flux in the tank 1. The guide hole 1703 and the reverse threaded spiral stirring blade 1702 work together during stirring, allowing the flux to be exchanged laterally in the tank 1, further enhancing the mixing effect of the flux.
[0040] In addition, the wire is transmitted through two sets of guide shafts 3 and pressed down into the tank 1 by two sets of pressing shafts 4 to fully contact the plating solution. During the transmission process, it moves along the corresponding guide groove 28, which improves the guiding of the wire during the transmission process. The sealing ring reduces the gap between the outer cover 25 and the filter box 18, which improves the sealing of the filter box 18.
