Description

Technical Field

[0001] This utility model relates to the field of stainless steel pickling equipment, specifically an environmentally friendly pickling equipment for corrosion-resistant stainless steel pipes. Background Technology

[0002] Stainless steel pickling is an industrial cleaning technology that typically uses pickling and passivation paste and pickling and passivation solution. The pickling and passivation paste performs pickling and passivation simultaneously, with the aim of removing oxides and other contaminants from the stainless steel surface to achieve a uniform silvery-white finish. The principle of pickling is to use acid solutions to remove oxide scale and rust from the steel surface, forming salts through chemical reactions that dissolve in the acid solution and are removed.

[0003] Stainless steel pickling generates acid mist, which escapes directly from the top of the pickling tank, easily causing environmental pollution. At the same time, the acid mist can be easily inhaled by operators, which can also lead to health problems for them. Therefore, there is an urgent need for a device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an environmentally friendly pickling equipment for corrosion-resistant stainless steel pipes, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly pickling device for corrosion-resistant stainless steel pipes, comprising a pickling tank, a U-shaped block fixedly installed at the top of the pickling tank, the U-shaped block having a groove inside, a box fixedly installed on the side of the pickling tank, two boxes being provided and symmetrically fixed on both sides of the pickling tank, a first pipe fixedly embedded at the top of the box, a second pipe fixedly installed at the top of the first pipe, a pad fixedly installed inside the box, the pad being U-shaped, a filter mechanism for facilitating acid filtration at the top of the pad, a limit block being movably embedded on the outside of the pad, an air pump fixedly installed at the bottom of the box, a third pipe fixedly installed at the input end of the air pump, when in use, the air pump is started, the air pump draws out the air inside the box, creating a negative pressure inside the box, thus creating a negative pressure inside the first pipe, and then the acid mist generated at the top of the pickling tank is drawn into the first pipe through the second pipe, filtered by the filter mechanism, and finally discharged by the air pump, preventing acid mist from escaping and causing pollution.

[0006] Preferably, the filtration mechanism includes a U-shaped frame, a handle, an activated carbon adsorption plate, and a chute. The U-shaped frame is slidably disposed on one side of the housing, the handle is fixed to one side of the U-shaped frame, and the chute is opened inside the U-shaped frame. Several chutes are provided, symmetrically arranged on both sides of the inside of the U-shaped frame. The activated carbon adsorption plate is slidably disposed inside the chute. In use, the U-shaped frame is slidably installed inside the housing, and then the limiting block is rotated to one side of the U-shaped frame to prevent the U-shaped frame from detaching from the housing. The inhaled acid mist is adsorbed when it passes through the activated carbon adsorption plate, thereby achieving a purification effect. The limiting block is rotated away from the side of the U-shaped frame at regular intervals, and then the U-shaped frame is pulled out by the handle, and then the activated carbon adsorption plate is pulled out to replace the activated carbon adsorption plate, ensuring the filtration effect.

[0007] Preferably, two U-shaped blocks are provided and symmetrically fixed on both sides of the top of the pickling tank.

[0008] Preferably, the second pipe is a multi-ended pipe, and the extension ends of the second pipe are fixed at the center and both sides of the U-shaped block, respectively.

[0009] Preferably, there are two limiting blocks, which are symmetrically installed on both sides of the pad block.

[0010] Preferably, the third pipe is fixedly inserted into the interior of the box.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. When using this utility model, the air pump is started, and the air pump draws out the air inside the box, so that the box is negatively pressured. This creates a negative pressure inside the first pipe, and then the acid mist generated at the top of the pickling tank can be drawn into the first pipe through the second pipe. Then it is filtered by the filter mechanism and finally discharged by the air pump to prevent the acid mist from escaping and causing pollution.

[0013] 2. In use, the U-shaped frame is slidably installed inside the box. Then, the limiting block is rotated to one side of the U-shaped frame to prevent the U-shaped frame from detaching from the box. The inhaled acid mist is adsorbed when it passes through the activated carbon adsorption plate, thus achieving a purification effect. The limiting block is rotated away from the U-shaped frame at regular intervals, and then the U-shaped frame is pulled out by the handle. The activated carbon adsorption plate can then be replaced to ensure the filtration effect. Attached Figure Description

[0018] 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.

[0019] Please see Figure 1-3 This utility model provides an environmentally friendly pickling device for corrosion-resistant stainless steel pipes, including a pickling tank 1. Two U-shaped blocks 2 are welded and fixed to the top of the pickling tank 1, symmetrically fixed on both sides of the top of the pickling tank 1. A groove 14 is formed inside the U-shaped blocks 2. Two boxes 5 are bolted to the sides of the pickling tank 1, symmetrically fixed on both sides of the pickling tank 1. A first pipe 4 is embedded and fixed to the top of the box 5. A second pipe 3 is fixed to the top of the first pipe 4 via a connecting valve. The second pipe 3 is a multi-ended pipe, with its extension ends fixed to the center and both sides of the U-shaped blocks 2. U-shaped pads 6 are welded and fixed inside the box 5. The system has a convenient filter mechanism for filtering acid. A limiting block 7 is movably embedded on the outside of the pad 6. There are two limiting blocks 7, which are symmetrically installed on both sides of the pad 6. An air pump 12 is fixed to the bottom of the box 5 by a mounting bracket. A third pipe 13 is fixed to the top input end of the air pump 12 by a connecting valve. The third pipe 13 is fixedly inserted into the inside of the box 5. When in use, the air pump 12 is started, and the air pump 12 draws out the air inside the box 5, so that a negative pressure is formed inside the box 5. This creates a negative pressure inside the first pipe 4. Then, the acid mist generated at the top of the pickling tank 1 can be drawn into the first pipe 4 through the second pipe 3, filtered by the filter mechanism, and finally discharged through the air pump 12 to prevent the acid mist from escaping and causing pollution.

[0020] The filtration mechanism includes a U-shaped frame 8, a handle 9, an activated carbon adsorption plate 11, and a chute 10. The U-shaped frame 8 slides on one side of the housing 5. The handle 9 is fixed to one side of the U-shaped frame 8 with bolts. Several chute 10s are opened inside the U-shaped frame 8, symmetrically arranged on both sides inside the U-shaped frame 8. The activated carbon adsorption plate 11 slides inside the chute 10. In use, the U-shaped frame 8 is slidably installed inside the housing 5, and then the limiting block 7 is rotated to one side of the U-shaped frame 8 to prevent the U-shaped frame 8 from detaching from the housing 5. The inhaled acid mist is adsorbed when it passes through the activated carbon adsorption plate 11, thereby achieving a purification effect. The limiting block 7 is rotated away from the side of the U-shaped frame 8 at regular intervals, and then the U-shaped frame 8 is pulled out by the handle 7, and then the activated carbon adsorption plate 11 is pulled out to replace it, ensuring the filtration effect.

[0021] Working principle: When in use, the air pump 12 is activated, which extracts the air from inside the chamber 5, creating a negative pressure inside the chamber 5. This creates a negative pressure inside the first pipe 4, allowing the acid mist generated at the top of the pickling tank 1 to be drawn into the first pipe 4 through the second pipe 3. The mist is then filtered by the filtration mechanism and finally discharged through the air pump 12, preventing the acid mist from escaping and causing pollution. During use, the U-shaped frame 8 is slidably installed inside the chamber 5, and then the limiting block 7 is rotated to one side of the U-shaped frame 8 to prevent the U-shaped frame 8 from detaching from the chamber 5. The absorbed acid mist is adsorbed by the activated carbon adsorption plate 11, thus achieving a purification effect. Periodically, the limiting block 7 is rotated away from the side of the U-shaped frame 8, and then the U-shaped frame 8 is pulled out by the handle 7. The activated carbon adsorption plate 11 can then be removed to replace the activated carbon adsorption plate 11, ensuring the filtration effect.
