Description

Technical Field

[0001] This utility model relates to the field of pickling additive mixing technology, and in particular to a pretreatment structure for mixing and feeding pickling additives. Background Technology

[0002] During the pickling process, various functional additives need to be precisely added to the acid solution to improve pickling efficiency, reduce acid loss, and protect the surface quality of the workpiece.

[0003] To address the aforementioned issues, existing patents have provided solutions. However, in the existing pickling additive mixing and feeding process, there is a lack of effective pretreatment when the additives are fed. Impurities mixed in the solid additives can easily enter the acid system directly, resulting in residual impurities on the surface of the workpiece after pickling. Moreover, solid additives are prone to clumping, making it difficult to dissolve quickly during the reaction. This prolongs the mixing time and can easily cause excessively high local concentrations, leading to excessive corrosion or uneven corrosion of the workpiece.

[0004] Therefore, a pretreatment structure for mixing and feeding pickling additives is proposed. Utility Model Content

Impurities mixed in the solid additives can easily enter the acid system directly, resulting in residual impurities on the surface of the workpiece after pickling. Moreover, solid additives are prone to agglomeration, which makes it difficult to dissolve quickly during the reaction.

Detailed Implementation

[0024] 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.

[0025] Please see Figure 1-6 The present invention provides the following technical solution:

[0026] A pretreatment structure for mixing and feeding pickling additives includes a substrate 1, a reaction tank 2 fixedly connected to the top of the substrate 1, a support frame 3 fixedly connected to the right side of the top of the substrate 1, a pretreatment component 4 provided on the top of the support frame 3, a screening component 5 provided on the top of the pretreatment component 4, the pretreatment component 4 including a pretreatment box 401 fixedly connected to the top of the support frame 3, a crushing chamber 402 opened inside the pretreatment box 401, a conveying cylinder 403 connected to the bottom of the crushing chamber 402, the side of the conveying cylinder 403 away from the pretreatment box 401 connected to the reaction tank 2, a drive motor 404 fixedly connected to the outside of the pretreatment box 401, a synchronous pulley 405 installed at the output end of the drive motor 404 through a transmission belt and a transmission wheel, a crushing roller 406 fixedly connected to the inside of the synchronous pulley 405, the side of the crushing roller 406 away from the synchronous pulley 405 rotatably connected to the pretreatment box 401, and a conveying blade 407 fixedly connected to the output end of the drive motor 404, the conveying blade 407 being located inside the conveying cylinder 403.

[0027] In this embodiment: by starting the drive motor 404 on the outside of the pretreatment box 401, the output end of the drive motor 404 drives the synchronous pulley 405 to rotate through the transmission belt and the transmission wheel. The synchronous pulley 405 then drives the crushing roller 406 fixedly connected to the inside to rotate in the crushing chamber 402. The rotating crushing roller 406 performs deep crushing treatment on the additives that fall in, refining the residual lumps and larger particles into a uniform and fine state, ensuring that they can be quickly dissolved when mixed with acid later. At the same time, the output end of the drive motor 404 synchronously drives the conveying blades 407 in the conveying cylinder 403 to rotate. The rotating conveying blades 407 generate driving force, which smoothly and continuously conveys the crushed additives in the crushing chamber 402 to the reaction tank 2 along the conveying cylinder 403, realizing the integrated operation of crushing and conveying, and avoiding the blockage or interruption of additives during the conveying process.

[0028] Specifically, such as Figure 4 As shown, the screening assembly 5 includes a screening box 501 fixedly connected to the top of the pretreatment box 401. A control motor 502 is fixedly connected to the outside of the screening box 501. A rotating disk 503 is fixedly connected to the output end of the control motor 502. A connecting rod 504 is rotatably connected to the inside of the rotating disk 503.

[0029] Specifically, such as Figure 4 As shown, a connecting frame 505 is rotatably connected to the bottom of the connecting rod 504, a screening plate 506 is fixedly connected inside the connecting frame 505, and the outer side of the connecting frame 505 is slidably connected to the screening box 501.

[0030] Specifically, such as Figure 4As shown, a reset support rod 507 is fixedly connected inside the screening box 501. The bottom of the reset support rod 507 passes through the connecting frame 505. A reset spring 508 is provided at the connection between the reset support rod 507 and the connecting frame 505.

[0031] In this embodiment: Before feeding, the cover plate 13 of the screening box 501 is opened, the solid pickling additive is put into the screening box 501, and then the cover plate 13 is closed. Then, the control motor 502 on the outside of the screening box 501 is started. The output end of the control motor 502 drives the rotating disk 503 to rotate. The rotating disk 503 is connected to the connecting rod 504 on the inside, which pulls the connecting frame 505 at the bottom of the connecting rod 504 to slide up and down along the inner wall of the screening box 501. Since the screening box 501 has a reset support rod 507 that passes through the connecting frame 505, and a reset spring 508 is provided at the connection between the reset support rod 507 and the connecting frame 505, the reset spring 508 extends and retracts when the connecting frame 505 slides up and down, which helps the connecting frame 505 to quickly reset. This allows the screening plate 506 fixed inside the connecting frame 505 to perform stable high-frequency vibration synchronously. Through the vibration of the screening plate 506, the dust and impurities in the solid pickling additive are separated out, ensuring that the purity and initial form of the additive entering the subsequent process are consistent.

[0032] Specifically, such as Figure 1 , Figure 5 As shown, an acid delivery seat 6 is connected to the left side of the reaction vessel 2, and an acid storage tank 7 is connected to the left side of the acid delivery seat 6.

[0033] Specifically, such as Figure 5 , Figure 6 As shown, a heating chamber 8 is provided inside the reaction vessel 2, and a heating wire 9 is provided inside the heating chamber 8. A controller 10 is fixedly connected to the outside of the reaction vessel 2, and the output end of the controller 10 is electrically connected to the heating wire 9.

[0034] In this embodiment: by setting up an acid delivery seat 6 and an acid storage tank 7, the acid storage tank 7 is used to pre-store the acid required for pickling, providing a raw material guarantee for the mixing reaction. When the pretreated additive is delivered to the reaction tank 2 through the delivery cylinder 403, the acid in the acid storage tank 7 flows steadily and continuously into the reaction tank 2 through the acid delivery seat 6 connected to it, realizing the precise mixing of acid and additive, and ensuring a stable supply of raw materials for the pickling working solution. By setting up a heating chamber 8, a heating wire 9, and a controller 10, when both the additive and the acid enter the reaction tank 2, the controller 10 on the outside of the reaction tank 2 is operated according to the temperature requirements of the mixed solution in the pickling process. The controller 10 sends a working command to the heating wire 9 in the heating chamber 8 through an electrical connection. After the heating wire 9 is activated, it generates heat, which is transferred to the mixed solution inside the reaction tank 2 through the heating chamber 8 to adjust the temperature of the mixed solution, so that the mixed solution reaches the appropriate temperature range for the reaction, effectively promoting the rapid and full fusion reaction of the additive and the acid, and ensuring that the performance of the pickling working solution meets the standards.

[0035] Specifically, such as Figure 1 , Figure 6 As shown, the bottom of the reaction vessel 2 is connected to a discharge pipe 11, and a control valve 12 is installed on the outside of the discharge pipe 11.

[0036] Specifically, such as Figure 2 As shown, a cover plate 13 is rotatably connected to the top of the screening box 501, and a pull rod 14 is fixedly connected to the top of the cover plate 13.

[0037] In this embodiment: By setting up a discharge pipe 11 and a control valve 12, after the additives and acid in the reaction tank 2 have been fully mixed and reacted to form an acid pickling working solution that meets the requirements of the acid pickling process, the operator opens the control valve 12 set on the outside of the discharge pipe 11. At this time, the acid pickling working solution in the reaction tank 2 is smoothly discharged along the discharge pipe 11 under its own gravity and accurately transported to the subsequent acid pickling process. By setting up a cover plate 13 and a pull rod 14, before feeding solid acid pickling additives, the operator pulls the pull rod 14 on the top of the cover plate 13 to open the cover plate 13 rotatably connected to the top of the screening box 501, exposing the feeding port of the screening box 501, so as to conveniently and quickly feed the solid acid pickling additives to be processed into the screening box 501. After feeding is completed, the cover plate 13 is closed to prevent additive dust from flying during the screening process and to prevent external impurities from entering the screening box 501.

[0038] Working principle: During the pretreatment of the pickling additive by mixing and feeding, the cover plate 13 is first opened by pulling the lever 14 on the cover plate 13. Then, the solid pickling additive to be processed is put into the screening box 501. Then, the control motor 502 is started. Then, the output end of the control motor 502 drives the rotating disk 503 connected to it to rotate. During the rotation of the rotating disk 503, the connecting rod 504 connected to its inner side pulls the connecting frame 505 connected to the bottom of the connecting rod 504 to slide up and down along the inner wall of the screening box 501. Since a reset support rod 507 that passes through the connecting frame 505 is fixed inside the screening box 501, and the connection between the reset support rod 507 and the connecting frame 505 is equipped with a reset mechanism. When the spring 508 and the connecting frame 505 slide up and down, the return spring 508 will extend and retract accordingly, thereby assisting the connecting frame 505 to quickly return to its original position. The screening plate 506 fixed inside the connecting frame 505 will vibrate stably up and down synchronously with the connecting frame 505. The vibration of the screening plate 506 realizes the vibration screening of solid pickling additives, effectively removing impurities mixed in the additives, ensuring that the purity and initial morphology of the additives entering the subsequent processes meet the standards. The screened solid pickling additives fall from the screening box 501 into the pretreatment box 401 below. At this time, the drive motor 404 on the outside of the pretreatment box 401 is started. The output end of the drive motor 404 drives the synchronous pulley 4 through the cooperation of the transmission belt and the transmission wheel. As the synchronous pulley 405 rotates, the crushing roller 406, fixedly connected to the inner side of the synchronous pulley 405, rotates within the crushing chamber 402, crushing the solid pickling additive that falls into the crushing chamber 402, refining the additive particles to a more uniform state, ensuring dissolution efficiency when mixed with acid later. Simultaneously, the drive motor 404 drives the conveying blades 407 to rotate, and the rotation of the conveying blades 407 transports the crushed additive from the crushing chamber 402 along the conveying cylinder 403 to the reaction tank 2, which is connected to the side of the conveying cylinder 403 away from the pretreatment tank 401. After the additive is delivered to the reaction tank 2, the left side of the reaction tank 2 is connected to the acid storage tank 7 via the acid conveying seat 6. The acid solution in tank 7 enters the reaction tank 2 through the acid solution delivery seat 6. At this time, the controller 10 is operated to make the output end of the controller 10 electrically connected to the heating wire 9 and control the heating wire 9 to work. The heat generated by the heating wire 9 adjusts the temperature of the additive and acid solution mixture in the reaction tank 2, providing a suitable temperature environment for the two to mix and react, promoting the full fusion and reaction of the additive and acid solution. When the additive and acid solution in the reaction tank 2 have completed the mixing and reaction and formed an acid pickling working solution that meets the requirements of the pickling process, the control valve 12 set on the outside of the discharge pipe 11 connected to the bottom of the reaction tank 2 is opened, and the mixed acid pickling working solution can be discharged along the discharge pipe 11 for use in subsequent acid pickling processes.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
