Description

Technical Field

[0001] This invention relates to the field of pickling tank technology, specifically to an automatic acid circulation stainless steel pickling tank. Background Technology

[0002] Stainless steel is a material with excellent corrosion resistance, and pickling is an indispensable step in the production and processing of stainless steel. After a period of use, the concentration of the pickling solution will decrease and fail to meet the pickling requirements. During the stainless steel production and processing, the pickling process generates a large amount of pickling wastewater containing heavy metals such as chromium and nickel, as well as fluorides. Pickling wastewater poses a significant threat to environmental pollution and human life. The heavy metals in pickling wastewater cannot be decomposed or destroyed by various common methods; they can only be moved and their physical and chemical forms changed. The waste generated from stainless steel pickling is quite complex. The common treatment method for pickling wastewater is a combination of chemical precipitation and lime methods. Pickling can still be carried out before the concentration of the pickling solution decreases to the pickling requirements. Directly treating it as pickling wastewater would result in a great waste, thereby increasing pickling costs.

[0003] According to Chinese Patent No. CN202020274189.4, an automatic circulating stainless steel pickling tank for acid includes a bottom cavity. A guide neck is fixedly installed on the top of the bottom cavity. A control plate is fixedly installed on the top of the guide neck. A liquid storage cavity is fixedly installed on the top of the control plate. A switch is movably installed on the left side of the liquid storage cavity. A liquid inlet area is opened on the top of the liquid storage cavity. A detachable filter tube is detachably installed on the right side of the liquid inlet area. A liquid delivery pipe is detachably installed on the right side of the detachable filter tube. A storage box is detachably installed on the right side of the liquid storage cavity. An air suction pump is detachably connected to the bottom of the storage box. A fixing plate is fixedly installed on the bottom of the air suction pump.

[0004] In summary, the shortcomings of the existing technology are that although it can remove odors and facilitate disassembly, a watermark will form on the inner wall of the pickling tank due to waste impurities after treatment, which can easily aggravate the odor and is not easy to clean. Therefore, there is still room for improvement. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the technical solution adopted by this invention to solve its technical problems is as follows:

[0006] An automatic acid circulation stainless steel pickling tank, specifically comprising:

[0007] The machine base has a vertical plate fixedly installed on its top. The vertical plate is embedded in the middle of the machine base. A heater is fixedly installed on the top left side of the front of the vertical plate. An acid washing device is movably installed on the right side of the front of the vertical plate. The acid washing device is used to adjust the acid washing state of the wastewater. The acid washing device is located at the top of the machine base.

[0008] The pickling device includes a hoop, with a thin strip movably inserted into the top of the hoop. A sleeve plate is movably fitted onto the top of the thin strip. The sleeve plate consists of two parts, an upper and a lower. The upper sleeve plate gradually moves downward under the action of vibration and slides along the outer surface of the thin strip. The size of the sleeve plate is larger than that of the thin strip. A chemical chamber is movably installed on the outer surface of the inner cylinder device. An inner cylinder device is movably installed on the inner surface of the sleeve plate. A tube is fixedly connected to the middle of the top of the inner cylinder device.

A turntable is movably fitted onto the outer surface of the middle part of the main shaft. A horizontal plate is rotatably installed at the top of the main shaft.

[0009] Furthermore, the diameter of the horizontal plate is larger than that of the turntable. The horizontal plate is made of stainless steel. The horizontal plate slides downwards and impacts the inclined plate, causing the inclined plate to deform outwards. The center lines of the horizontal plate, the main shaft, and the turntable are on the same straight line. The inner cylinder device also includes a cylindrical device. An assembly block is fixedly installed in the middle of the inner wall of the cylindrical device. A pressure plate is movably inserted into the top of the assembly block. The pressure plate penetrates the interior of the assembly block, and a base is fixedly connected to the bottom end of the pressure plate. A base is movably sleeved on the outer surface of the main shaft. An inclined plate is embedded in the outer side wall of the base. The upper part of the inclined plate consists of a plate body and a rotating component. The plate body on the upper part of the inclined plate is fixedly mounted... The assembly is equipped with a sleeve, and a sliding component is movably installed on the inner side wall of the top of the sleeve. The bottom arc surface of the sliding component adsorbs and blocks wastewater, which gradually enters to the left side through the second pipe. A central shaft ring is fixedly installed at the shaft center of the sleeve, and a slot is opened at the shaft center of the sleeve. The central shaft ring is located above the shaft center of the sleeve. A base plate is fixedly connected to the bottom end of the inclined plate. The base plate is irregularly shaped, and adhesive is applied between the base plate and the inclined plate. The base plate extends through to the interior of one side of the assembly block. The width of the base plate is wider than the width of the assembly block. The assembly block is fixed to the interior of the cylindrical device by bolts. A slot corresponding to the main shaft is opened at the shaft center of the base plate.

[0010] Furthermore, the screening device includes a housing, a first through pipe fixedly installed on the front of the housing, a rotating shaft rotatably installed on the inner side wall of the housing, a chuck fixedly installed on the outer surface of the rotating shaft, wastewater impacts the chuck and moves, the chuck twists, the chuck swings, and the chuck swings, causing the extension plate to move synchronously, the extension plate is movably installed on the top of the chuck, a wiping plate is fixedly installed on the side of the extension plate, a screen plate is slidably connected to the outer surface of the wiping plate, a torsion member is movably installed at the bottom of the inner cavity of the housing, the interior of the housing is hollow, the rotating shaft passes through the interior of the chuck, the chuck has a slot in the middle corresponding to the rotating shaft, the wiping plate is made of stainless steel and is embedded in the side of the extension plate, and the screen plate itself has evenly distributed slots.

[0011] Furthermore, the stirring device includes a tank body, a disc body fixedly installed on the top of the inner wall of the tank body, an arc plate fixedly installed on the side of the disc body, a flat frame fixedly connected to the side of the arc plate away from the disc body, a rod body rotatably installed in the middle of the inner wall of the tank body, an adjusting plate fixedly connected to the outer surface of the rod body, the adjusting plate rotates due to impact, the rotation of the adjusting plate gradually moves the metal material contained at the bottom, the wastewater impacts the flat frame and moves, the activated carbon chemical components contained inside the flat frame treat the wastewater, a ring is inserted and installed at the bottom of the disc body, a torsion bar is movably installed in the middle of the inner surface of the ring, and a support is movably installed at the bottom of the flat frame.

[0012] This invention provides an automatic acid circulation stainless steel pickling tank. It has the following beneficial effects:

[0013] 1. This automatic circulating stainless steel pickling tank uses the flushing action inside the sleeve and the bottom arc surface of the sliding part to adsorb and block the wastewater. The wastewater gradually enters the left side through the second pipe, thus ensuring that the equipment has the basic conditions for rapid treatment and laying a good foundation for subsequent treatment.

[0014] 2. This automatic circulating stainless steel pickling tank uses a cylindrical device where wastewater impacts the interior, causing internal fluctuations. These fluctuations create vibrations within the cylindrical device. When the device vibrates, two sleeve plates are present. The top sleeve plate gradually moves downwards under the vibration, sliding along the outer surface of the thin strip. A corresponding groove is provided between the thin strip and the top sleeve plate. The top sleeve plate covers the outer surface of the thin strip, providing rapid protection and reducing accidental contact or impact from the outside, thus improving the safety performance of the inner cylinder device.

[0015] 3. This automatic circulating stainless steel pickling tank utilizes a horizontal plate that moves downwards. As the horizontal plate slides downwards, it impacts the sidewall of the chemical chamber, releasing the chemical components inside. These components then enter the cylindrical device. The horizontal plate slides along the outer surface of the main shaft, creating a displacement tendency. As it slides downwards, it impacts an inclined plate, causing the inclined plate to deform outwards. The inclined plate adheres to the inner wall of the cylindrical device, providing support. It also adheres to and bears a significant portion of the wastewater, thus reducing corrosion on the inner wall of the cylindrical device. Due to the opposing forces, the plate above the inclined plate moves closer to the horizontal plate. A rotating component above the inclined plate gradually collects strip-shaped impurities from the wastewater. The bottom of the rotating plate provides auxiliary support to the inclined plate, ensuring rapid collection of wastewater impurities while maintaining a close fit and protecting the inner wall of the cylindrical device. This enhances the stability of the equipment and reduces the need for additional protection of the inner wall of the cylindrical device.

[0016] 4. This automatic circulating stainless steel pickling tank uses a pressure plate that penetrates the interior of the assembly block to drive the base. As the pressure plate penetrates the interior of the assembly block, it gradually impacts the side of the chassis, causing the chassis to vibrate. This vibration of the chassis agitates the wastewater inside, reducing the adhesion of wastewater residue to the side wall of the cylindrical device. This weakens the conditions for watermark formation on the inner side wall, thereby ensuring the cleanliness and anti-sticking effect of the equipment.

[0017] 5. This automatic circulating stainless steel pickling tank rotates due to the impact of the adjusting plate. The rotation of the adjusting plate gradually moves the metal substances contained at the bottom. The wastewater impacts the flat frame and moves. The activated carbon chemical components inside the flat frame treat the wastewater. The flat frame creates an up-and-down bumping trend, and the arc plate generates up-and-down vibration accordingly. The torsion bar and ring parts gradually reinforce the arc plate to improve stability, thereby changing the position of the metal and transforming its physical and chemical form to facilitate better pickling treatment, prevent accumulation in one place from affecting pickling efficiency, and ensure clean pickling.

[0018] 6. This automatic circulating stainless steel pickling tank uses a sieve plate to screen particulate impurities in the wastewater. The wastewater impacts the chuck, causing it to twist and swing. This swinging motion of the chuck causes the extension plate to move synchronously, and the wiping plate moves in conjunction with it. The wiping plate gradually cleans the inside of the tank, and the cleaned water is gradually transferred to the heater through the first pipe, ultimately ensuring that the equipment has a rapid cleaning function and achieving the purpose of quickly filtering wastewater.

Detailed Implementation

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Examples of the invention are given for illustrative and descriptive purposes only and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0034] Example 1: Please refer to Figures 1-7 This invention provides a technical solution: an automatic acid circulation stainless steel pickling tank, specifically comprising:

[0035] The base 1 has a vertical plate 2 fixedly installed on the top of the base 1. The vertical plate 2 is embedded in the middle of the interior of the base 1. A heater 3 is fixedly installed on the top left side of the front of the vertical plate 2. An acid washing device 4 is movably installed on the right side of the front of the vertical plate 2. The acid washing device 4 is used to adjust the acid washing state of the wastewater.

[0036] The pickling device 4 includes a hoop 41, with a thin strip 42 movably inserted into the top of the hoop 41. A sleeve 43 is movably sleeved at the top of the thin strip 42. The sleeve 43 consists of two parts, an upper and a lower part, and there are two sleeves 43. The top sleeve 43 gradually moves downward under the action of vibration and slides along the outer surface of the thin strip 42. The size of the sleeve 43 is larger than that of the thin strip 42. A chemical chamber 44 is movably installed on the outer surface of the inner cylinder device 45. The inner cylinder device 45 is movably installed on the inner surface of the sleeve 43. A pipe 46 is fixedly connected to the middle of the top of the inner cylinder device 45. A second through pipe 40 is movably inserted into the outer surface of the sleeve 43. A main shaft 47 is rotatably installed at the axis of the inner cylinder device 45. A turntable 48 is movably sleeved on the outer surface of the middle part of the main shaft 47. A horizontal plate 49 is rotatably installed at the top of the main shaft 47.

[0037] The diameter of the horizontal plate 49 is larger than that of the turntable 48. The horizontal plate 49 is made of stainless steel. The horizontal plate 49 slides downward and strikes the inclined plate 455, causing the inclined plate 455 to deform outward. The center lines of the horizontal plate 49, the main shaft 47, and the turntable 48 are on the same straight line. The inner cylinder device 45 also includes a cylindrical device 451. An assembly block 452 is fixedly installed in the middle of the inner wall of the cylindrical device 451. A pressure plate 454 is movably inserted into the top of the assembly block 452 and penetrates the interior of the assembly block 452. A base 453 is fixedly connected to the bottom end of the pressure plate 454. A base plate 450 is movably sleeved on the outer surface of the main shaft 47. An inclined plate 455 is embedded in the outer side wall of the base plate 450. The upper part of the inclined plate 455 consists of a plate body and a rotating part. A sleeve is fixedly installed on the plate body above the inclined plate 455. 456. A sliding member 457 is movably installed on the inner side wall of the top of the sleeve 456. The bottom arc surface of the sliding member 457 adsorbs and blocks the wastewater. The wastewater gradually enters to the left side through the second pipe 40. A central shaft ring 458 is fixedly installed at the shaft center of the sleeve 456, and a slot is opened at the shaft center of the sleeve 456. The central shaft ring 458 is located above the shaft center of the sleeve 456. A base plate 450 is fixedly connected to the bottom end of the inclined plate 455. The base plate 450 is irregularly shaped. Adhesive is applied between the base plate 450 and the inclined plate 455. The base plate 450 extends through to the interior of one side of the assembly block 452. The width of the base 453 is wider than the width of the assembly block 452. The assembly block 452 is fixed to the interior of the cylindrical device 451 by bolts. A slot corresponding to the main shaft 47 is opened at the shaft center of the base plate 450.

[0038] In use, wastewater is first added from the top slot of the cylindrical device 451. Wastewater is flushed into the inside of the cylindrical device 451 and comes into contact with the sleeve 456. The inside of the sleeve 456 has a scouring effect. The bottom arc surface of the sliding part 457 adsorbs and blocks the wastewater. The wastewater gradually enters the left side through the second pipe 40, thereby ensuring that the equipment has the basic conditions for rapid treatment and laying a good foundation for subsequent treatment.

[0039] When wastewater is added to the inner cylinder device 45, the protection of the inside of the cylindrical device 451 is crucial. If it is accidentally broken, the consequences would be unimaginable. Therefore, when the cylindrical device 451 needs to be protected, the inside of the cylindrical device 451 will fluctuate due to the impact of the wastewater. Under the action of the fluctuation, the cylindrical device 451 will vibrate. When the cylindrical device 451 vibrates, there are two sleeves 43. The top sleeve 43 gradually moves downward under the action of the vibration. The top sleeve 43 slides along the outer surface of the thin strip 42. There is a corresponding groove between the thin strip 42 and the top sleeve 43. The top sleeve 43 covers the outer surface of the thin strip 42, and the top sleeve 43 forms a rapid protection function, reducing external accidental contact or impact, thereby improving the safety performance of the inner cylinder device 45.

[0040] When the inner cylinder device 45 is subjected to high temperature or chemical corrosion, the inner wall of the cylindrical device 451 is prone to corrosion and peeling, which is detrimental to processing safety. Therefore, reinforcement is required. Moisture passes through the center of the central ring 458 and impacts the horizontal plate 49, causing it to shift downwards. As the horizontal plate 49 slides downwards, it impacts the side wall of the chemical chamber 44, releasing the chemical components inside the chemical chamber 44. These chemical components then enter the interior of the cylindrical device 451. The horizontal plate 49 slides along the outer surface of the main shaft 47, creating a tendency to shift. The horizontal plate 49 slides downwards and impacts the inclined plate 455, causing it to move. The inclined plate 455 then moves... The outward expansion deformation causes the inclined plate 455 to adhere to the inner wall of the cylindrical device 451, forming a support for the cylindrical device 451. The inclined plate 455 adheres to and bears a large portion of the wastewater, thus reducing corrosion of the inner wall of the cylindrical device 451. Due to the opposing forces, the plate above the inclined plate 455 moves towards the horizontal plate 49. The rotating part above the inclined plate 455 gradually collects strip-shaped debris and other impurities in the wastewater. The bottom of the turntable 48 provides auxiliary support for the inclined plate 455, thereby ensuring the rapid collection of internal wastewater impurities. At the same time, it ensures the adhesion and protection of the inner wall of the inner cylindrical device 45, improves the stability of the equipment, and reduces the protective effect on the inner wall of the cylindrical device 451.

[0041] When watermarks on the inner wall of the cylindrical device 451 need to be treated, the wastewater gradually falls downwards and impacts the pressure plate 454, causing it to move. The pressure plate 454 is displaced downwards and penetrates the interior of the assembly block 452, pushing the base 453 to operate. As the pressure plate 454 penetrates the interior of the assembly block 452, it gradually impacts the side of the chassis 450, causing the chassis 450 to vibrate. The chassis 450 shakes the wastewater inside, reducing the adhesion of the wastewater stains inside the cylindrical device 451 to the side wall, thereby weakening the conditions for watermark formation on the inner wall and ensuring the cleanliness and anti-sticking effect of the equipment.

[0042] Example 2: Please refer to Figure 1 , Figures 8-10 The present invention provides a technical solution: the pickling device 4 is located on the top of the base 1, and the screening device 5 is movably installed in the middle of the top front of the base 1. The screening device 5 is used to adjust the impurities in the wastewater.

[0043] The screening device 5 includes a housing 51. A first through pipe 52 is fixedly installed on the front of the housing 51. A rotating shaft 53 is rotatably installed on the inner side wall of the housing 51. A chuck 54 is fixedly installed on the outer surface of the rotating shaft 53. Wastewater impacts the chuck 54 and moves it, causing the chuck 54 to twist and swing. The swinging of the chuck 54 causes the extension plate 55 to move synchronously. The extension plate 55 is movably installed on the top of the chuck 54. A wiping plate 56 is fixedly installed on the side of the extension plate 55. A screen plate 57 is slidably connected to the outer surface of the wiping plate 56. A torsion member 58 is movably installed at the bottom of the inner cavity of the housing 51. The interior of the housing 51 is hollow. The rotating shaft 53 passes through the interior of the chuck 54. A slot corresponding to the rotating shaft 53 is opened in the middle of the chuck 54. The wiping plate 56 is made of stainless steel and is embedded in the side of the extension plate 55. The screen plate 57 itself has evenly distributed slots.

[0044] When there is a lot of wastewater inside the stirring device 6, the wastewater gradually overflows and needs to be screened and filtered. The wastewater gradually enters the interior of the tank 51 through the stirring device 6. The screen plate 57 screens the particulate impurities in the wastewater. The wastewater hits the chuck 54 and moves, causing the chuck 54 to twist and swing. The swinging of the chuck 54 causes the extension plate 55 to move synchronously. The extension plate 55 is linked to the wiping plate 56, which gradually cleans the interior of the tank 51. The cleaned water is gradually transferred to the heater 3 through the first pipe 52, ultimately ensuring that the equipment has a fast and clean function and achieving the purpose of fast wastewater filtration.

[0045] Example 3: Please refer to Figures 1-13 The present invention provides a technical solution: based on embodiment 1, a stirring device 6 is movably installed on the back of the upright plate 2. The stirring device 6 is used to adjust the accumulation state of metal impurities, and a circulation pump 7 is fixedly installed on the top left side of the front of the upright plate 2.

[0046] The stirring device 6 includes a tank body 61. A disc body 62 is fixedly installed on the top of the inner wall of the tank body 61. An arc plate 63 is fixedly installed on the side of the disc body 62. A flat frame 64 is fixedly connected to the side of the arc plate 63 away from the disc body 62. A rod body 65 is rotatably installed in the middle of the inner wall of the tank body 61. An adjusting plate 66 is fixedly connected to the outer surface of the rod body 65. The adjusting plate 66 rotates under impact. The rotation of the adjusting plate 66 gradually moves the metal material contained at the bottom. The wastewater impacts the flat frame 64 and moves. The activated carbon chemical component inside the flat frame 64 treats the wastewater. A ring 68 is inserted and installed at the bottom of the disc body 62. A torsion bar 67 is movably installed in the middle of the inner surface of the ring 68. A support 69 is movably installed at the bottom of the flat frame 64.

[0047] When it is necessary to change the position of metal substances in wastewater, which tend to accumulate in one place and cause pickling inefficiency, the wastewater enters the circulation pump 7 through the second pipe 40. The circulation pump 7 is connected to the tank body 61 through the vertical plate 2. Therefore, the wastewater enters the tank body 61 through the circulation pump 7 and gradually impacts the adjusting plate 66. The adjusting plate 66 rotates due to the impact, and the rotation of the adjusting plate 66 gradually moves the metal substances contained at the bottom. The wastewater hits the flat frame 64 and moves. The activated carbon chemical components inside the flat frame 64 treat the wastewater. The flat frame 64 forms an up-and-down bumping trend, and the arc plate 63 is also vibrating up and down. The twisting bar 67 and the ring 68 gradually reinforce the arc plate 63 to improve stability and change the position of the metal, thereby changing their physical and chemical forms to facilitate better pickling treatment, prevent accumulation in one place from affecting the pickling efficiency, and ensure clean pickling.

[0048] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
