Description

Technical Field

[0001] This utility model relates to the field of bar and wire processing technology, specifically to an environmentally friendly and water-saving coil pickling device. Background Technology

[0002] Pickling is the process of removing the oxide layer from the surface of metallic materials using acid (usually sulfuric acid or hydrochloric acid). This method is commonly used to improve the surface quality of metals, enhance their corrosion resistance, and prepare them for subsequent treatments. Pickling can effectively remove rust, scale, and corrosion from steel surfaces, enhancing the effectiveness of subsequent material treatments.

[0003] Patent document CN216688326U discloses a pickling device, including a feeding device, an acid immersion device, a rinsing device, and a drying device. The feeding device is used to place the steel strip to be treated onto the production line. The inlet of the acid immersion device is connected to the outlet of the feeding device, and the acid immersion device is used to immerse the steel strip in acid. An acid circulation component is provided at the bottom of the acid immersion device. The inlet of the rinsing device is connected to the outlet of the acid immersion device, and the rinsing device is used to rinse the surface of the steel strip of residual acid. The rinsing device is equipped with a spray component and is connected to an acid separation component. The inlet of the drying device is connected to the outlet of the rinsing device, and the drying device is used to dry the rinsed steel strip and stack it. This utility model has a simple structure and a high degree of automation.

[0004] Pickling is required when processing bar and wire rods. Existing pickling equipment consists of direct rinsing or tank washing. Although rinsing or tank washing is effective, it consumes a lot of raw materials during the pickling process. Improper handling may also lead to a large amount of water being wasted, especially when discharging untreated acid. In addition, although the front and back of the bar and wire rods can be rinsed during the rinsing process, the bar and wire rods are usually packaged in coils, which results in insufficient rinsing. Utility Model Content

[0005] The purpose of this utility model is to provide an environmentally friendly and water-saving reel pickling device to solve the problems mentioned in the background art. Currently, when rinsing bars and wires, direct rinsing or tank washing is used, but the rinsing process consumes a lot of raw materials. Due to improper handling, a large amount of water may still be wasted, especially in untreated acid solutions. At the same time, although the front and back can be rinsed during the rinsing process of bars and wires, the bars and wires are all packaged in reels, which leads to insufficient rinsing.

[0015] Preferably, a second gear is fixedly installed at the right end of the front mounting shaft in the flushing chamber, and a rack is slidably connected to the upper end of the right end of the flushing chamber. An electric push rod is fixedly installed at the rear end of the right end of the flushing chamber. The output end of the electric push rod is fixedly connected to the rear end of the rack, and the rack and the second gear mesh with each other.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This environmentally friendly and water-saving reel pickling device significantly reduces water consumption and effectively reduces waste liquid discharge through an efficient circulation system. It also reduces acid consumption by utilizing high-performance pickling effect, thereby reducing the impact on the environment. At the same time, by filtering it, impurities and dissolved dirt generated during the pickling process can be effectively removed. Furthermore, the combination of filtration and circulation system can reduce the amount of new acid used. Then, by reciprocating tumbling, the acid can cover all corners of the workpiece, making the cleaning process more uniform and avoiding local over-cleaning or under-cleaning, thereby improving the consistency of cleaning.

[0017] 1. The system includes a base, cleaning tank, inlet pipe, outlet pipe, connecting pipe, nozzle, heat exchanger, circulating pump, and manual control valve. Three cleaning tanks are located inside the base, allowing the rod / wire material to be cleaned within them. The inlet and outlet pipes are fixedly installed at the rear end of the base, extending into the cleaning tank. The front end of the inlet pipe is fixedly connected to the rear end of the heat exchanger, and the front end of the heat exchanger is fixedly connected to the inlet of the circulating pump. This allows for the heating of the extracted acid solution. The system also includes a manual control valve at the outlet of the circulating pump. The output pipes are fixedly connected together, and then the connecting pipes are fixedly connected to the output pipes in a "U" shape. Nozzles are also fixedly installed at both ends of the connecting pipes. The rotation of the circulation pump can extract the acid solution inside the cleaning tank and heat it through the cooperation between the input pipe and the heat exchanger. At the same time, the water output can be controlled by the cooperation between the circulation pump and the manual control valve. Then, the water extracted by the circulation pump is discharged through the cooperation between the output pipe, the connecting pipe and the nozzles. Through the efficient circulation system, water consumption is significantly reduced, waste liquid discharge is effectively reduced, and the high-performance pickling effect reduces acid consumption, thereby reducing the impact on the environment.

[0018] 2. It is equipped with an input pipe, a first filter, an output pipe, and a second filter. Three sets of first filters are arrayed on the body of the input pipe, and three sets of second filters are arrayed on the body of the output pipe. The first and second filters on the input and output pipes can filter the extracted acid solution. By filtering, impurities and dissolved dirt generated during the pickling process can be effectively removed. At the same time, the use of fresh acid solution can be reduced by cooperating with the filtration and circulation system.

[0019] 3. The system is equipped with an installation shaft, water injection pipe, first gear, high-pressure nozzle, synchronous pulley, belt, second gear, rack, and electric push rod. The output end of the electric push rod drives the rack to slide at the right end of the rinsing chamber. The rack then meshes with the second gear on the right end of the installation shaft, causing the second gear to rotate the water injection pipe. The front and rear synchronous pulleys in the rinsing chamber are connected by a belt sleeve, which in turn rotates the water injection pipes at both ends of the rinsing chamber. Simultaneously, the first gear is fixedly installed on the left end of the installation shaft in the rinsing chamber. The upper and lower first gears in the rinsing chamber mesh with each other, causing the water injection pipe to form a flipping structure. Since the water injection pipe is arrayed with high-pressure nozzles, the flipping of the water injection pipe drives the high-pressure nozzles to perform all-round rinsing. The reciprocating flipping allows the acid to cover all corners of the workpiece, making the cleaning process more uniform and avoiding local over-cleaning or under-cleaning, thereby improving the consistency of cleaning.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 This utility model provides a technical solution: an environmentally friendly and water-saving reel pickling device, comprising: a base 1, a rinsing chamber 2, a cleaning tank 3, an input pipe 4, a first filter 5, an output pipe 6, a second filter 7, a connecting pipe 8, a nozzle 9, a heat exchanger 10, a circulating pump 11, a manual control valve 12, a water inlet 13, a mounting shaft 14, a water inlet pipe 15, a first gear 16, a high-pressure nozzle 17, a folded corrugated pipe 18, a synchronous pulley 19, a belt 20, a second gear 21, a rack 22, and an electric push rod 23.

[0029] First, as attached Figure 1 and attached Figure 2As shown, when the coiled bar wire undergoes acid pickling, the external tube is first connected to the water inlet 13 on the base 1 and the folded corrugated pipe 18 on the rinsing chamber 2. The base 1 has three sets of cleaning tanks 3 inside. The coiled bar wire is placed inside the cleaning tank 3, and the external acid solution is fixedly connected to the water inlet 13 on the left side of the base 1, allowing a large amount of cleaning solution to be injected into the cleaning tank 3 on the left side of the base 1. Simultaneously, the circulation pump 11 can be started while the acid solution is being injected into the cleaning tank 3 on the left side of the base 1. An input pipe 4 is fixedly installed at the rear end of the base 1, and an output pipe 6 is fixedly installed at the front end of the base 1. A heat exchanger 10 is also fixedly installed at the rear end of the right side of the base 1, with its rear end fixedly connected to the front end of the input pipe 4. The input end of the circulation pump 11 is fixedly connected to the front end of the heat exchanger 10, and a manual control valve 12 is fixedly installed on the output end of the circulation pump 11. The front end of the manual control valve 12 is connected to the rear end of the output pipe 6. The ends are fixedly connected together, and the pipes of the inlet pipe 4 and the outlet pipe 6 extend through the interior of the cleaning tank 3. The acid solution inside the cleaning tank 3 on the left side of the base 1 can be extracted by the operation of the circulation pump 11. At the same time, when the acid solution is extracted, it can also be heated by the heat exchanger 10. The extracted acid solution is discharged through the cooperation between the circulation pump 11 and the outlet pipe 6. The water output can also be controlled by turning the manual control valve 12. Since the pipe of the outlet pipe 6 extends through the interior of the cleaning tank 3, a connecting pipe 8 is fixedly installed at the right end of the cleaning tank 3. The connecting pipe 8 is U-shaped and fixedly connected to the outlet pipe 6. Nozzles 9 are fixedly installed at both ends of the connecting pipe 8. The extracted acid solution can be discharged through the nozzles 9 through the cooperation between the connecting pipe 8 and the nozzles 9. At the same time, the acid solution is drawn in and out of the cleaning tank 3 in a uniform manner through the outlet pipe 6, so as to realize the recycling of the acid solution inside the cleaning tank 3, reduce the consumption of acid solution, and reduce the impact on the environment.

[0030] As attached Figure 1 and attached Figure 2 As shown, when the acid solution inside the cleaning tank 3 is recycled through the cooperation of the input pipe 4, the output pipe 6 and the circulation pump 11, three sets of first filters 5 are arrayed on the pipe body of the input pipe 4, and three sets of second filters 7 are arrayed on the pipe body of the output pipe 6. The cooperation between the first filters 5 and the second filters 7 can filter the extracted acid solution, so as to effectively remove impurities and dissolved dirt generated during the pickling process. At the same time, the cooperation between the filtration and the circulation system can reduce the amount of new acid solution used.

[0031] As attached Figure 1 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 and attached Figure 6 As shown, when processing coiled wire rods, after rinsing in the tank, the coiled wire rods are lifted up. Folded corrugated pipes 18 are fixedly installed at both the upper and lower ends of the side wall of the rinsing chamber 2, and the folded corrugated pipes 18 are fixedly connected to the body of the water injection pipe 15. This allows the folded corrugated pipes 18 to be fixedly connected to the external acid solution. High-pressure nozzles 17 are arrayed on the body of the water injection pipe 15, and the cooperation between the water injection pipe 15 and the high-pressure nozzles 17 allows for rinsing of the wire rods. Simultaneously, the rack 22 can be activated during rinsing, and the wire rods are then rinsed. Both ends of the washing chamber 2 are rotatably connected to mounting shafts 14. The mounting shafts 14 are symmetrically arranged about the horizontal line of the washing chamber 2 and about the vertical center line of the washing chamber 2. They are also fixedly connected to the left end of the water injection pipe 15 and the right end of the water injection pipe 15 to the right end of the washing chamber 2. A rack 22 is slidably connected to the front end of the right end of the washing chamber 2, and an electric push rod 23 is fixedly installed on the right end of the washing chamber 2. The push rod 23 is then fixedly installed on the shaft of the right end of the washing chamber 2. A second gear 21 is provided, which meshes with an electric push rod 23. The extension and retraction of the electric push rod 23 causes the rack 22 to slide, which in turn drives the mounting shaft 14 to rotate via the second gear 21. Since a synchronous pulley 19 is fixedly mounted on the right side of the mounting shaft 14 in the flushing chamber 2, and the front and rear synchronous pulleys 19 in the flushing chamber 2 are connected by a belt 20, the water injection pipes 15 at both ends of the flushing chamber 2 rotate synchronously. Then, the water injection pipes 15 fixed on the left side of the front mounting shaft 14 in the flushing chamber 2 rotate synchronously. The first gear 16 is installed, and the upper first gear 16 in the rinsing chamber 2 and the lower first gear 16 in the rinsing chamber 2 mesh with each other. The interaction between the first gears 16 drives the water injection pipe 15 to form a flipping structure. The reciprocating flipping of the water injection pipe 15 can synchronously drive the high-pressure nozzle 17 to rotate up and down. At the same time, when the water injection pipe 15 reciprocates, it can drive the folded corrugated pipe 18 to stretch and contract, thereby cleaning the bar wire in all aspects, so that the acid solution can cover all corners, making the cleaning process more uniform and avoiding local over-cleaning or under-cleaning, thus improving the consistency of cleaning.
