Description

Technical Field

[0001] This utility model relates to the field of pickling equipment, specifically a hydraulic cylinder pipe online circulating pickling device. Background Technology

[0002] As is well known, hydraulic cylinder tubing is a high-precision steel pipe material processed by cold drawing or hot rolling, mainly used to manufacture pneumatic or hydraulic components, such as cylinders or oil cylinders. During the production process, hydraulic cylinder tubing needs to be soaked in hydrochloric acid solution in an acid pickling tank to remove metal impurities and oil stains from the inner wall and surface of the metal tube. After acid pickling, the hydrochloric acid solution will contain precipitated metal impurities and oil stains. The online circulating acid pickling device for hydraulic cylinder tubing is a device used for online acid pickling treatment of hydraulic cylinder tubing, aiming to improve the efficiency of acid pickling and cleaning and reduce the impact on the environment. Traditional acid pickling devices will contain a large amount of metal impurities and oil stains in the acid pickling solution when acid pickling hydraulic cylinders, and after acid pickling, the used acid pickling solution will be directly discharged into the acid pickling waste liquid tank for waste liquid discharge treatment, while replacing it with new acid pickling solution. This not only increases the cost of acid pickling hydraulic cylinder tubing, but also requires separate treatment of the metal impurities and oil stains in the discharged acid pickling waste liquid.

[0003] To address the aforementioned issues, Chinese Patent Publication No. CN117385371A discloses an acid pickling device for hydraulic cylinder pipes. This device uses a motor to drive a long, strip-shaped electromagnet to rotate and remove metallic impurities from the hydrochloric acid solution, facilitating subsequent sorting and processing of pickling residues. Simultaneously, a rotating primary filter intercepts oil stains in the solution. This combination of oil filtration and electromagnetic adsorption of metallic impurities allows the hydrochloric acid solution in the tank to be reused, reducing the cost of pickling hydraulic cylinder pipes. Furthermore, after a significant amount of metallic impurities are adsorbed onto the electromagnet's surface, the motor reverses the rotation, causing the electromagnet's surface to be repeatedly cleaned by a brush, thus accelerating the removal of metallic impurities. This not only facilitates the discharge of metallic impurities but also eliminates the need to remove the electromagnet for surface cleaning, promoting its continued use.

[0004] While the comparative patent addresses the issue of pickling solutions containing large amounts of metallic impurities and oil, and directly discharges the used pickling solution into a waste pickling tank for waste disposal after pickling, while simultaneously replacing it with a new pickling solution, this not only increases the cost of pickling hydraulic cylinder pipes but also requires separate treatment of the metallic impurities and oil in the discharged waste pickling solution. However, this device requires energizing the electromagnetic ring when the solution enters the tank, causing the electromagnetic ring to attract metallic substances, which then need to be brushed off with a brush. This increases the difficulty of cleaning and reduces the efficiency of removing the attracted metallic substances.

[0005] Regarding the aforementioned related technologies, this device has the drawback that the electromagnetic ring attracts metal substances, and then a brush is used to brush off the metal substances, which increases the difficulty of cleaning and reduces the efficiency of cleaning the attracted metal substances.

It solves the problem that the electromagnetic ring adsorbs metal substances, and the use of a brush to brush off the metal substances increases the difficulty of cleaning and reduces the efficiency of cleaning adsorbed metal substances.

[0011] As a preferred embodiment of this utility model, a discharge pipe is fixedly connected to the other side of the pump body, one end of the discharge pipe extends into the interior of the tank, and the discharge pipe is fixedly connected to the tank body.

[0012] As a preferred embodiment of this utility model, the power generation component includes a bearing embedded in the inner wall of the tank, a rotating shaft fixedly sleeved on the inner ring of the bearing, a flip plate fixedly connected to the outer wall of the rotating shaft, and the other end of the rotating shaft fixedly connected to one side of the generator.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides an online circulating pickling device for hydraulic cylinder pipes, which has the following beneficial effects:

[0017] 1. When cleaning metal debris, the solution no longer enters the tank, thus the tilting plate and rotating shaft stop rotating, and the generator stops energizing the electromagnetic rod. The motor's operation drives the threaded rod to rotate, which in turn drives the scraper to move downwards. The scraper scrapes the material off the outer wall of the electromagnetic rod, thus removing the adsorbed metal debris. The outer wall of the tank has a sealed door. Opening the sealed door allows the scraped metal debris to be collected, thereby reducing the difficulty of cleaning and improving the efficiency of cleaning the adsorbed metal material.

[0018] 2. The pump body works by drawing the pickling solution from the pickling tank through the suction pipe. When the solution enters the tank, it will cause the tilting plate to flip, which in turn will drive the rotating shaft to rotate. The generator converts the mechanical force of the rotating shaft into electricity, thus realizing the power supply. The generator can conduct electricity to the cable through the conductive wire, so that the electromagnetic rod can be energized, which can attract metal debris in the solution, thereby realizing automatic power generation, saving electricity resources and improving environmental protection.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Example 1

[0025] Reference Figure 1-3 This is the first embodiment of the present invention, which provides an online circulating pickling device for hydraulic cylinder pipes, including a pickling tank 1, an installation plate 2 fixedly connected to one side of the pickling tank 1, a storage tank 4 fixedly connected to one side of the installation plate 2, an installation frame 3 fixedly connected to one side of the installation plate 2, a tank body 8 fixedly connected to the top of the installation frame 3, a water pumping component provided on one side of the installation plate 2, a power generation component provided inside the tank body 8, an installation block 13 fixedly connected inside the tank body 8, an electromagnetic rod 15 fixedly connected to the inner wall of the installation block 13, a cable 14 fixedly connected to the top of the electromagnetic rod 15, a generator 11 fixedly connected to one side of the installation plate 2, a conductive wire 12 fixedly connected to one side of the generator 11, and the cable 14 fixedly connected to the conductive wire 12. Thus, the generator 11 can conduct electricity to the cable 14 through the conductive wire 12, thereby energizing the electromagnetic rod 15, which can then adsorb metal debris in the solution. A cleaning component is provided inside the tank body 8.

[0026] Reference Figure 1 The pumping component includes a pump body 5, which is fixedly connected to the mounting plate 2. A suction pipe 6 is fixedly connected to one side of the pump body 5. One end of the suction pipe 6 extends into the interior of the pickling tank 1. The suction pipe 6 is fixedly connected to the pickling tank 1. The pump body 5 is an existing device and will not be explained in detail here. The pump body 5 can extract the pickling solution from the interior of the pickling tank 1 through the suction pipe 6.

[0027] Furthermore, a discharge pipe 7 is fixedly connected to the other side of the pump body 5. One end of the discharge pipe 7 extends into the interior of the tank body 8. The discharge pipe 7 is fixedly connected to the tank body 8. After the pump body 5 extracts the pickling solution from the pickling tank 1 through the extraction pipe 6, it will discharge the solution into the interior of the tank body 8 through the discharge pipe 7.

[0028] Reference Figure 1-3The power generation component includes a bearing 9 embedded in the inner wall of the tank 8. A rotating shaft 20 is fixedly sleeved on the inner ring of the bearing 9. A flip plate 10 is fixedly connected to the outer wall of the rotating shaft 20. The other end of the rotating shaft 20 is fixedly connected to one side of the generator 11. When the solution enters the interior of the tank 8, it will cause the flip plate 10 to flip, which will in turn cause the rotating shaft 20 to rotate. The generator 11 converts the rotational mechanical force of the rotating shaft 20 into electricity, thereby realizing the function of power supply.

[0029] Specifically, the mounting block 13 has a circular structure, and the cable 14 extends through the mounting block 13 to the outside of the tank body 8. The mounting block 13 can play an effective supporting role.

[0030] Reference Figure 1-3 The cleaning components include a motor 16, one side of which is fixedly connected to one side of the mounting plate 2. The output end of the motor 16 is fixedly connected to a threaded rod 17 via a coupling. The threaded rod 17 is rotatably connected to the tank body 8. A lifting plate 18 is threadedly sleeved on the outer wall of the threaded rod 17. A scraper 19 is fixedly connected to one side of the lifting plate 18. The scraper 19 has a circular structure. The inner wall of the scraper 19 is slidably sleeved with the electromagnetic rod 15. The operation of the motor 16 can drive the threaded rod 17 to rotate, which in turn can drive the scraper 19 to move downward. The scraper 19 can scrape the material on the outer wall of the electromagnetic rod 15, thereby scraping the adsorbed metal debris. A sealing door is opened on the outer wall of the tank body 8. Opening the sealing door can collect the scraped metal debris.

[0031] During use, the pump body 5 can extract the pickling solution from the pickling tank 1 through the suction pipe 6. When the solution enters the tank body 8, it will cause the tilting plate 10 to tilt, which will in turn drive the rotating shaft 20 to rotate. The generator 11 converts the rotational mechanical force of the rotating shaft 20 into electricity, which can then be used to supply electricity. The generator 11 can conduct electricity to the cable 14 through the conductive wire 12, so that the electromagnetic rod 15 can be energized, which can then adsorb the metal debris in the solution.

[0032] When cleaning metal debris, the solution no longer enters the interior of the tank 8, and the tilting plate 10 and the rotating shaft 20 stop rotating. Consequently, the generator 11 stops energizing the electromagnetic rod 15. The operation of the motor 16 can drive the threaded rod 17 to rotate, which in turn can drive the scraper 19 to move downward. The scraper 19 can scrape the outer wall of the electromagnetic rod 15, thereby scraping off the adsorbed metal debris. A sealing door is provided on the outer wall of the tank 8. Opening the sealing door can collect the scraped metal debris.
