Description

Technical Field

[0001] This utility model relates to the field of steel strip pickling technology, specifically to a steel strip pickling apparatus. Background Technology

[0002] Pickling of steel strip is a common process in steel production, mainly used to remove iron oxide scale, rust, and other impurities from the surface of steel strip to improve its surface quality and facilitate subsequent processing. The main steps of pickling include immersion, pickling, and rinsing.

[0003] According to a public announcement (Announcement No.: CN213866431U), a steel strip pickling device includes a support base, a pickling chamber, a washing chamber, a drying chamber, a conveying device, and a machine body. A water tank is installed on the upper surface of the support base body. Several high-pressure water guns are installed on the upper surface inside the machine body, and several high-pressure water guns are also installed on the lower surface inside the machine body. A second support plate is installed on the peripheral surface of the machine body, and a second water pump is installed on the upper surface of the second support plate. The high-pressure water guns are connected to the water tank through a second water pipe and the second water pump. The drying chamber includes a wiping block, which includes an upper wiping block and a lower wiping block. Both the upper and lower wiping blocks are installed on the peripheral surface inside the machine body, and both surfaces of the upper and lower wiping blocks are provided with a water-absorbing layer. This utility model uses high-pressure water guns to rinse the steel strip, completely removing the pickling liquid remaining on the steel strip after pickling. By using wiping blocks, water stains on the steel strip after washing can be removed.

[0004] The aforementioned patent achieves complete removal of residual pickling liquid from the steel strip after pickling by using components such as the base and pickling chamber in cooperation. By setting up water wiping blocks, it can remove water stains from the steel strip after washing. However, it cannot better solve the technical problem of automating the cleaning of residues in the pickling tank of steel strip without manual cleaning. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a strip steel pickling device, which solves the technical problem of automating the cleaning of residues in the pickling tank of strip steel without the need for manual cleaning.

[0006] According to one aspect, at least one embodiment of the present invention provides a steel strip pickling device, comprising: a base plate, a pickling tank fixedly connected to the top of the base plate, a driving device provided on the top of the base plate, a drain pipe penetratingly connected to the side of the pickling tank, a pipe cap inserted into one end of the drain pipe, and a cleaning device provided on the inner side of the pickling tank. The cleaning device includes a groove formed on the inner side of the pickling tank. An electric telescopic rod is fixedly connected to the inner side of the groove, and a push plate is fixedly connected to one end of the electric telescopic rod. A sealing gasket is fixedly connected to the side of the push plate. A collection trough is formed at the bottom inner side of the pickling tank. This cleaning device can automatically clean the pickling tank, ensuring the safety of the tank environment. It also helps to efficiently recover dirt and liquid, and avoids direct contact between operators and the liquid in the pickling tank, preventing injury to operators.

[0007] For example, in at least one embodiment of the present invention, a steel strip pickling device further includes: the diameter of the push plate is the same as the diameter of the groove, and the side of the push plate is slidably connected to the inner side of the groove. This design mainly ensures that the cleaning equipment is efficient, stable, and less prone to failure during operation, thus optimizing the cleaning process.

[0008] The bottom of the push plate has a groove, and a compression spring is fixedly connected to the top inner side of the groove. This design increases the stability, flexibility, and adaptability of the equipment through the action of the compression spring, making the cleaning process smoother and more efficient, while also improving the durability of the equipment and reducing the risk of failure.

[0009] One end of the compression spring is fixedly connected to an arc-shaped scraper, the diameter of which is the same as the diameter of the chute. This design, by combining the functions of the compression spring and the arc-shaped scraper, ensures both thorough cleaning and improves the stability and reliability of the equipment. The perfect cooperation between the arc-shaped scraper and the chute helps maintain smooth operation of the equipment, avoids dirt accumulation or jamming, and ensures an efficient and continuous cleaning process.

[0010] The side of the arc-shaped scraper is slidably connected to the inner side of the chute, and the top of the collection trough is located on the displacement trajectory of the arc-shaped scraper. This design optimizes the cleaning process by precisely aligning the displacement trajectory of the arc-shaped scraper with the top of the collection trough, ensuring thoroughness, continuity, and efficiency in cleaning. It not only improves the operating efficiency of the equipment but also reduces the negative impact of dirt on the environment and equipment, lowering maintenance costs and the risk of equipment failure.

[0011] One end of the drain pipe is located directly in front of the collection tank. Multiple compression springs are arranged in a linear array along the top inner side of the chute. This is to maintain stable operation of the equipment during liquid discharge, preventing excessive liquid retention or unstable movement of equipment components.

[0012] According to another aspect, at least one embodiment of this utility model also provides a steel strip pickling device, comprising: a residue scraping device disposed on the top of the base plate, the residue scraping device including a bracket, the bottom of the bracket being fixedly connected to the top of the base plate, a sliding groove being formed on the side of the bracket, a sliding block being slidably connected to the inner side of the sliding groove, a support plate being fixedly connected to the side of the sliding block, a pressure spring being fixedly connected to the bottom of the support plate, a fixing plate being fixedly connected to one end of the pressure spring, and a lower arc scraper being fixedly connected to the top of the fixing plate. This residue scraping device design, through the coordinated operation of components such as the lower arc scraper, pressure spring, sliding groove, and sliding block, can achieve efficient and precise scraping effects, while also possessing self-adaptive and shock-absorbing functions to protect the equipment from damage and improve the equipment's service life and working efficiency. This design not only optimizes the cleaning process but also improves the stability and maintenance convenience of the equipment.

[0013] For example, in at least one embodiment of the present invention, a strip pickling device further includes: multiple pressure springs arranged in a linear array along the bottom of a support plate. The design of multiple pressure springs arranged linearly along the bottom of the support plate is primarily for uniform pressure distribution, improved stability, and extended service life. It also allows for adjustment of the force as needed, ensuring the uniformity and precision of the scraping effect. This design provides more reliable and durable performance, optimizing the overall scraping process.

[0014] Multiple fixed plates, lower arc scrapers, support plates, and pressure springs are provided, and these components are symmetrical about the vertical central axis of the sliding block. This multiple arrangement and symmetrical design of the components ensures that the equipment maintains good working condition under long-term, high-load operation, improving reliability and service life.

[0015] Two sliding grooves are provided, and the two sliding grooves are symmetrical about the vertical central axis of the bracket. The symmetrical design of the sliding grooves ensures the uniform distribution of force on the equipment, improves the system's balance, stability and accuracy, and helps to reduce friction and wear, extend the service life of the equipment and improve work efficiency.

[0016] The beneficial effects of the embodiments of this utility model are as follows: This invention utilizes a combination of components such as an electric telescopic rod, a push plate, and an arc-shaped scraper. When cleaning residue from the pickling tank is required, the pipe cover is opened to allow the liquid to flow out. The electric telescopic rod is then activated, driving the push plate horizontally. As the push plate disengages from the groove, a compression spring pushes the arc-shaped scraper vertically, ejecting it. The arc-shaped scraper then moves horizontally, pushing the residue at the bottom of the pickling tank into a collection tank. The operator then drains the residue from the collection tank through a drain pipe. This achieves automatic cleaning of the pickling tank, ensuring a safe environment, facilitating efficient recovery of waste and liquid, and preventing direct contact between operators and the liquid, thus avoiding potential injury.

[0017] In this invention, components such as a bracket, sliding groove, sliding block, and pressure spring work together to achieve the desired cleaning effect. The operator moves the sliding block within the sliding groove to adjust the desired position. After pickling, the strip steel is collected and passes through a lower arc scraper, which removes any residue, resulting in a clean, residue-free strip. This achieves efficient and precise scraping, while also providing self-adaptation and shock absorption to protect the equipment from damage and improve its lifespan and efficiency. This design not only optimizes the cleaning process but also enhances the stability and ease of maintenance of the equipment. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0022] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product.

[0026] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] like Figures 1-6 As shown, it illustrates a steel strip pickling device according to an embodiment of the present invention, comprising: a base plate 1, a pickling tank 2 fixedly connected to the top of the base plate 1, a driving device 3 provided on the top of the base plate 1, a drain pipe 4 penetratingly connected to the side of the pickling tank 2, a pipe cap 5 inserted into one end of the drain pipe 4, and a cleaning device 6 provided on the inner side of the pickling tank 2. The cleaning device 6 includes a groove 61 located on the inner side of the pickling tank 2. An electric telescopic rod 62 is fixedly connected to the inner side of the groove 61. A push plate 63 is fixedly connected to one end of the electric telescopic rod 62, and a sealing gasket 64 is fixedly connected to the side of the push plate 63. A collection trough 65 is provided at the bottom inner side of the pickling tank 2. This cleaning device 6 enables automatic cleaning of the pickling tank 2, ensuring the safety of the tank environment. It also facilitates the efficient recovery of contaminants and liquids, and prevents operators from directly contacting the liquid in the pickling tank 2, thus preventing injury to operators.

[0028] In some examples, the diameter of the push plate 63 is the same as the diameter of the groove 61, and the side of the push plate 63 is slidably connected to the inner side of the groove 61. This design is mainly to ensure that the cleaning equipment is efficient, stable and less prone to failure during operation, thus optimizing the cleaning process.

[0029] The bottom of the push plate 63 has a groove 66, and a compression spring 67 is fixedly connected to the top inner side of the groove 66. This design increases the stability, flexibility and adaptability of the equipment through the action of the compression spring 67, making the cleaning process smoother and more efficient, while also improving the durability of the equipment and reducing the risk of failure.

[0030] One end of the compression spring 67 is fixedly connected to an arc-shaped scraper 68, the diameter of which is the same as the diameter of the chute 66. This design, by combining the functions of the compression spring 67 and the arc-shaped scraper 68, ensures both thorough cleaning and improves the stability and reliability of the equipment. The perfect fit between the arc-shaped scraper 68 and the chute 66 helps maintain smooth operation of the equipment, avoids dirt accumulation or jamming, and ensures an efficient and continuous cleaning process.

[0031] The side of the arc-shaped scraper 68 is slidably connected to the inner side of the chute 66, and the top of the collection trough 65 is located on the displacement trajectory of the arc-shaped scraper 68. This design optimizes the cleaning process by precisely aligning the displacement trajectory of the arc-shaped scraper 68 with the top of the collection trough 65, ensuring thoroughness, continuity, and efficiency in cleaning. It not only improves the operating efficiency of the equipment but also reduces the negative impact of dirt on the environment and equipment, lowering maintenance costs and the risk of equipment failure.

[0032] One end of the drain pipe 4 is located directly in front of the collection tank 65. Multiple compression springs 67 are arranged in a linear array along the top inner side of the slide 66. This is to maintain the smooth operation of the equipment when discharging liquid and to avoid excessive liquid retention or unstable movement of equipment components.

[0033] For example, such as Figures 1-6 As shown, when it is necessary to clean the residue inside the pickling tank 2, the pipe cover 5 is opened to allow the liquid in the pickling tank 2 to flow out. Then, the electric telescopic rod 62 is activated, which drives the push plate 63 to move horizontally. When the push plate 63 moves horizontally and disengages from the groove 61, the compression spring 67 pushes the arc-shaped scraper 68 to move vertically through its own elastic force, causing it to pop out. Then, the arc-shaped scraper 68 moves horizontally, pushing the residue at the bottom of the pickling tank 2 horizontally and pushing it into the collection tank 65. Then, the operator discharges the residue in the collection tank 65 through the drain pipe 4. When cleaning is completed, the electric telescopic rod 62 retracts, driving the push plate 63 to move back to its original position. The push plate 63 moves back to its original position, driving the arc-shaped scraper 68 to move horizontally. When the arc-shaped scraper 68 moves horizontally to the groove 61, the bottom of the groove 61 at the bend of the arc-shaped scraper 68 pushes the arc-shaped scraper 68 to move vertically upward, causing the arc-shaped scraper 68 to move back to the slide 66.

[0034] like Figures 1-6As shown, this invention illustrates a steel strip pickling device according to another embodiment, comprising: a residue scraping device 7 disposed on the top of a base plate 1; the residue scraping device 7 includes a bracket 71, the bottom of which is fixedly connected to the top of the base plate 1; a sliding groove 72 is formed on the side of the bracket 71; a sliding block 73 is slidably connected to the inner side of the sliding groove 72; a support plate 74 is fixedly connected to the side of the sliding block 73; a pressure spring 75 is fixedly connected to the bottom of the support plate 74; a fixing plate 76 is fixedly connected to one end of the pressure spring 75; and a lower arc scraper 77 is fixedly connected to the top of the fixing plate 76. This residue scraping device 7, through the coordinated operation of components such as the lower arc scraper 77, the pressure spring 75, the sliding groove 72, and the sliding block 73, achieves efficient and precise scraping, while also possessing self-adaptive and shock-absorbing functions to protect the equipment from damage and improve its service life and working efficiency. This design not only optimizes the cleaning process but also enhances the stability and ease of maintenance of the equipment. In some examples, multiple pressure springs 75 are arranged in a linear array along the bottom of the support plate 74. This linear array of multiple pressure springs 75 along the bottom of the support plate 74 is primarily designed to distribute pressure evenly, improve stability, and extend service life. It also allows for adjustment of the force as needed, ensuring uniformity and precision in the scraping effect. This design provides more reliable and durable performance, optimizing the overall scraping process.

[0035] Multiple fixed plates 76, lower arc scrapers 77, support plates 74, and pressure springs 75 are provided, and these multiple fixed plates 76, lower arc scrapers 77, support plates 74, and pressure springs 75 are symmetrical about the vertical central axis of the sliding block 73. The multiple arrangement and symmetrical design of these components are to ensure that the equipment can maintain good working condition under long-term, high-load operation, thereby improving reliability and service life.

[0036] There are two sliding grooves 72, which are symmetrical about the vertical central axis of the bracket 71. The symmetrical design of the sliding grooves 72 ensures the uniform distribution of force on the equipment, improves the balance, stability and accuracy of the system, and helps to reduce friction and wear, extend the service life of the equipment and improve work efficiency.

[0037] For example, such as Figures 1-6 As shown, the operator moves the sliding block 73 to slide in the sliding groove 72 to adjust the required position. Then, the strip steel after pickling is collected. The strip steel passes through the lower arc scraper 77, which pushes the pressure spring 75 to contract. The lower arc scraper 77 scrapes off the residue on the strip steel, so that the collected strip steel achieves a clean and residue-free effect.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
