Technical Field

[0001] This invention relates to the field of dephosphorization equipment technology in iron and steel smelting, and more specifically, to a dephosphorization device. Background Technology

[0002] Currently, most descaling systems use a box-type design. After the hot-rolled steel strip enters the box, the door is immediately closed, and the steel billet is flushed under high pressure to remove surface impurities and oxide layers. Otherwise, during the cleaning process, fragments such as iron oxide scale can easily fly out, which may not only injure operators but also pollute the working environment, thus creating safety hazards.

[0003] To ensure operational safety, current cabinet doors are typically driven by motors. However, frequent starting and stopping of the drive equipment increases power consumption, leading to higher energy costs. Furthermore, the frequent opening and closing of hydraulic doors also increases the failure rate. Summary of the Invention

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed, they are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0033] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0034] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0035] Current descaling systems generally employ a box-type design, characterized by a door at both the front and rear. The box is filled with evenly spaced high-pressure water pipes, each equipped with a nozzle for high-pressure spraying. During operation, hot-rolled steel plates (referred to as "red billet 20") are conveyed into the box into the system. The system first opens the front door; after the red billet 20 passes through, the door closes immediately. Then, the billet 20 is flushed under high pressure to remove surface impurities and oxide layers.

[0036] The main reason for adopting a box-type design is that without enclosed spraying, fragments such as iron oxide scale are easily scattered, which could not only injure operators but also pollute the working environment, thus creating safety hazards. Therefore, box-type descaling systems have become the preferred configuration in the industry.

[0037] However, there are some problems with the existing technology: 1. The opening and closing process of the door needs to be coordinated with the conveying of the red steel billet 20 and the start and stop of the roller motor, and also needs to be coordinated with the hydraulic system, making the operation relatively complicated; 2. The frequent start and stop of multiple devices increases the power consumption, leading to an increase in energy costs; 3. The frequent opening and closing of the hydraulic door leads to a high failure rate.

[0038] Based on the above issues, please refer to Figures 1 to 6 This invention provides a descaling device 10, which uses a multi-layer chain 300 to replace the door structure in the hydraulic system. The chain 300 driving method simplifies the door operation process, effectively reduces production costs, lowers the opening and closing failure rate, and effectively solves the above-mentioned problems.

[0039] However, this modification also faces new problems. Chain 300 is prone to corrosion when in contact with red steel billet 20 and under high-pressure water conditions. Once corrosion occurs, it needs to be replaced. The usual practice is to inspect and replace chain 300 while the machine is stopped, which is a time-consuming process and not conducive to maintaining the efficient operation of the production line.

[0040] Therefore, the dephosphorization device 10 provided by the present invention can not only solve some of the shortcomings of the original technology by adopting the modification scheme of driving the door with chain 300, but also solve the problems of maintenance needs and extended production line downtime caused by chain 300 corrosion.

[0041] In detail, the phosphorus removal device 10 includes a phosphorus removal box 100, a mounting rod 200, and a chain 300.

[0042] The phosphorus removal box 100 is provided with an opening 110; the mounting rod 200 is detachably installed on the phosphorus removal box 100; there are multiple chains 300, which are detachably hung on the mounting rod 200 to cover the opening 110.

[0043] In this embodiment, the steel billet 20 to be dephosphorized is conveyed into and out of the dephosphorization box 100 through the opening 110. After the steel billet 20 to be dephosphorized enters the dephosphorization box 100, the mounting rod 200 with multiple chains 300 can be installed at the opening 110 of the dephosphorization box 100 to cover the opening 110 and prevent iron oxide scale and other fragments from splashing out of the dephosphorization box 100 during the cleaning process, thereby avoiding injury to operators and pollution of the working environment. After the chains 300 rust, the mounting rod 200 can be removed from the dephosphorization box 100, and multiple chains 300 can be removed from the mounting rod 200. Multiple new chains 300 can then be reattached to complete the replacement of the chains 300. The assembly efficiency is high and the use cost is low.

[0044] Furthermore, the mounting rod 200 has multiple limiting parts 210 protruding along its length, and the multiple limiting parts 210 are staggered on both sides of the mounting rod 200 in opposite directions, and the chain 300 is disposed between two adjacent limiting parts 210.

[0045] In this embodiment, multiple limiting portions 210 are provided on the mounting rod 200 at equal intervals along the length direction of the mounting rod 200 to limit the chain 300. That is, each chain 300 is hung between two adjacent limiting portions 210 on the mounting rod 200 to ensure that the multiple chains 300 can be evenly distributed on the mounting rod 200, and to prevent the chains 300 from sliding on the mounting rod 200 and causing multiple chains 300 to concentrate on one side of the mounting rod 200 and expose the opening 110 of the descaling box 100.

[0046] It is worth mentioning that "multiple limiting parts 210 are staggered on both sides of the mounting rod 200 in opposite directions" means that, as shown in the figure, multiple limiting parts 210 are distributed in two rows on both sides of the mounting rod 200, and the midpoint of any two limiting parts 210 in the same row corresponds to one limiting part 210 in the other row.

[0047] Because each link of chain 300 is waist-shaped, therefore, during installation, as Figure 3 As shown, the mounting rod 200 is rotated so that the limiting parts 210 located on both sides of the mounting rod 200 are positioned on the upper and lower sides of the mounting rod 200, thereby facilitating the hanging of the chain 300; after multiple chains 300 are hung, the mounting rod 200° is rotated again, as shown. Figure 4 As shown, the limiting parts 210 located on the upper and lower sides of the mounting rod 200 are positioned on the left and right sides of the mounting rod 200, so that the two rows of limiting parts 210 respectively limit the multiple chains 300.

[0048] In order to facilitate the rotation of the mounting rod 200, a rod head 220 is provided at the end of the mounting rod 200. The rod head 220 is used to drive the mounting rod 200 to rotate under the action of external force.

[0049] In this embodiment, the rod head 220 is square in shape.

[0050] Furthermore, there are multiple mounting rods 200, and all of the mounting rods 200 can be detachably installed in the descaling box 100.

[0051] In this embodiment, by setting multiple parallel mounting rods 200, multiple chains 300 are hung on the multiple mounting rods 200, thereby increasing the distribution density of the multiple chains 300 and effectively shielding the iron oxide scale and other fragments splashed during the cleaning process.

[0052] Optionally, such as Figure 5 As shown, the number of mounting rods 200 can be three, that is, three rows of chains 300 are hung on three mounting rods 200.

[0053] Furthermore, the phosphorus removal device 10 also includes a first mounting member 400, with multiple mounting rods 200 arranged side by side on the first mounting member 400, and the first mounting member 400 is detachably mounted on the phosphorus removal box 100.

[0054] In this embodiment, by mounting multiple mounting rods 200 side by side on the first mounting member 400, it is convenient to install the multiple mounting rods 200 with chains 300 on the phosphorus removal box 100.

[0055] Furthermore, the phosphorus removal device 10 also includes a second mounting member 500, which is disposed on the top of the opening 110 of the phosphorus removal box 100, and the first mounting member 400 is detachably disposed on the second mounting member 500.

[0056] It is worth mentioning that the second mounting component 500 can be welded to the descaling box 100. Of course, it can also be fixed by other connection methods, which are not specifically limited here.

[0057] Furthermore, the second mounting member 500 is provided with a mounting groove 510, the bottom wall of the mounting groove 510 is provided with a mounting hole 520, and the area of ​​the top opening 110 of the mounting groove 510 is larger than the area of ​​the mounting hole 520. The shape of the first mounting member 400 matches the shape of the mounting groove 510, and the first mounting member 400 is detachably mounted on the mounting groove 510.

[0058] In this embodiment, the outer contour shape of the first mounting member 400 matches the inner wall contour shape of the mounting groove 510, and the area of ​​the top opening 110 of the mounting groove 510 is larger than the area of ​​the mounting hole 520, so that the first mounting member 400 can be stably installed in the mounting groove 510. Under the gravity of the first mounting member 400, the mounting rod 200 and the chain 300, the first mounting member 400 can be more tightly locked in the mounting groove 510, thereby improving the structural stability of the first mounting member 400 and the second mounting member 500.

[0059] Understandably, when the first mounting component 400 is installed into the mounting slot 510, the chain 300 hanging on the mounting rod 200 passes through the mounting hole 520 and extends vertically downward under the action of gravity to block the opening 110 of the descaling box 100.

[0060] In detail, the width of the mounting groove 510 gradually decreases in the vertically downward direction, so that the first mounting member 400 and the second mounting member 500 fit tightly together when the first mounting member 400 is installed in the mounting groove 510.

[0061] In this embodiment, the cross-section of the mounting groove 510 is approximately V-shaped.

[0062] Furthermore, the phosphorus removal box 100 has openings 110 on both opposite side walls. There are two first mounting parts 400 and two second mounting parts 500. The two second mounting parts 500 are respectively located in the two openings 110, and the two first mounting parts 400 are detachably located in the two second mounting parts 500.

[0063] In this embodiment, the steel billet 20 enters the descaling box 100 through one of the openings 110 for cleaning and can exit through the other opening 110; and a first mounting member 400 and a second mounting member 500 are provided in both openings 110, that is, a chain 300 is provided in both openings 110, so as to effectively block the two openings 110.

[0064] Furthermore, the two ends of the mounting rod 200 are hung on the first mounting component 400, and the first mounting component 400 is also provided with a cover plate 410, which is covered on both ends of the mounting rod 200 by fasteners.

[0065] In this embodiment, by covering the end of the mounting rod 200 with a cover plate 410 and fixing the cover plate 410 with fasteners such as bolts, the mounting rod 200 is fixed and prevented from falling off the first mounting member 400.

[0066] Furthermore, the dephosphorization device 10 also includes a conveying roller 600, and a dephosphorization box 100 is disposed on the conveying roller 600. The conveying roller 600 is used to convey the steel billet 20 to be dephosphorized.

[0067] In this embodiment, after the steel billet 20 to be dephosphorized is conveyed to the dephosphorization box 100 by the conveying roller 600, the mounting rod 200 with the chain 300 is installed at the opening 110 of the dephosphorization box 100 to form the box door of the dephosphorization box 100, so that the dephosphorization operation can be carried out safely. After cleaning, the cleaned steel billet 20 can be conveyed out of the dephosphorization box 100 by the conveying roller 600, thereby realizing the automated operation of the dephosphorization box 100.

[0068] In summary, this invention provides a descaling device 10. The steel billet 20 to be descaled is conveyed into and out of the descaling box 100 through an opening 110. After the steel billet 20 enters the descaling box 100, a mounting rod 200 with multiple chains 300 is installed at the opening 110 of the descaling box 100 to block the opening and prevent iron oxide scale and other debris from splashing out of the descaling box 100 during the cleaning process, thus avoiding injury to operators and pollution of the working environment. If the chains 300 rust, the mounting rod 200 can be removed from the descaling box 100, followed by the removal of all chains 300 from the mounting rod 200, and then multiple new chains 300 can be reinstalled. This process improves the assembly efficiency of the descaling device 10 and significantly reduces operating costs.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
