Description

Technical Field

[0001] This utility model relates to the field of pickling technology, specifically to a pickling equipment for the production and processing of highway guardrail panels. Background Technology

[0002] Pickling is a crucial step in the production and processing of highway guardrail panels. Traditional pickling equipment often suffers from uneven pickling and low efficiency, which not only affects the quality of the guardrail panels but also increases production costs.

[0003] According to a public disclosure (publication number: CN217709690U), a pickling device for highway guardrail production and processing includes a pickling tank with an internal pickling structure. The pickling structure comprises two water pipes, two water pumps, several branch pipes, several nozzles, and a swaying section. The two water pipes are symmetrically installed on the inner wall of the pickling tank, and the two water pumps are installed on the two water pipes. This utility model relates to the technical field of guardrail processing equipment. Before the guardrail is slowly lowered into the pickling solution, the solution is sprayed onto the surface of the guardrail to pre-clean it, allowing the oxide scale and rust on the guardrail to react. When the guardrail is lowered into the solution, the fluctuation of the solution creates a slight impact on the guardrail, causing the oxide scale and rust to fall off quickly. This improves the pickling speed, increases production efficiency, and ensures the pickling quality.

[0004] The aforementioned application utilizes structures such as spray nozzles and a swaying mechanism to achieve chemical fluctuations during the pre-cleaning and pickling processes of the guardrail panels, thereby improving the pickling effect. However, this equipment still has room for improvement in terms of structural complexity and ease of operation. Furthermore, its structure is relatively complex. Therefore, we propose a pickling device for the production and processing of highway guardrail panels. Utility Model Content

[0009] The end of the tensioning column away from the fixed base plate is fixedly connected to the bottom of the diverter plate. There are two tensioning columns, which are symmetrically distributed along the vertical central axis of the diverter plate. Their function is to increase the stability of the diverter plate during operation.

[0010] The number of spray columns is set to several and arranged linearly along the circumference of the spray pipe. The side cross-section of the fixing plate is set to L-shape, which is used to spray evenly so that the product is sprayed uniformly.

[0015] The circumferential surface of the transmission column penetrates the side of the soaking tank, and the circumferential surface of the secondary shaft also penetrates the side of the soaking tank.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[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 1-5 As shown, it illustrates an acid pickling device for highway guardrail production and processing in one embodiment of the present invention, comprising: a sliding groove 2 fixedly connected to the top of a fixed base plate 1, a hoisting device 3 provided on the inner side of the sliding groove 2, an immersion tank 4 fixedly connected to the top of the fixed base plate 1, and a spraying device 5 provided on the side of the immersion tank 4.

[0028] The spraying device 5 includes a fixed plate 501. A dual-output shaft motor 502 is fixedly connected to the side of the fixed plate 501. A water pump 503 is fixedly connected to the output shaft of the dual-output shaft motor 502. A connecting pipe 504 is fixedly connected through the side of the soaking tank 4. The end of the connecting pipe 504 away from the soaking tank 4 is fixedly connected to the input end of the water pump 503. An output pipe 505 is fixedly connected to the top of the water pump 503. A diverter plate 506 is fixedly connected to the end of the output pipe 505 away from the water pump 503. A spray pipe 507 is fixedly connected through the side of the diverter plate 506. A spray column 508 is fixedly connected to the side of the spray pipe 507. A filter box 509 is fixedly connected through the circumference of the connecting pipe 504. A filter disc 510 is inserted into the top of the filter box 509.

[0029] In some examples, a filter plate 6 is fixedly connected to the inner side of the soaking tank 4, a reinforcing plate 7 is fixedly connected to the end of the spray pipe 507 away from the diversion plate 506, and a tensioning column 8 is fixedly connected to the top of the fixed base plate 1. Its function is to act as a filter to prevent the spray pipe 507 from becoming clogged.

[0030] The end of the tensioning column 8 away from the fixed base plate 1 is fixedly connected to the bottom of the diverter plate 506. There are two tensioning columns 8, which are symmetrically distributed along the vertical central axis of the diverter plate 506. Their function is to increase the stability of the diverter plate 506 during operation.

[0031] The number of spray columns 508 is set to a certain extent, and they are arranged linearly along the circumference of the spray pipe 507. The side section of the fixing plate 501 is set to L-shape, which is used to spray evenly so that the product is sprayed evenly.

[0032] The connecting pipe 504 penetrates the interior of the diversion plate 506, and the interior of the diversion plate 506 penetrates the interior of the spray pipe 507. The spray column 508 is located above the soaking tank 4, and its function is to ensure the stable flow of acid.

[0033] For example, such as Figures 1-5 As shown, during operation, when the user needs to place the guardrail panel into the soaking tank 4, the dual-shaft motor 502 is started. The output shaft of the dual-shaft motor 502 drives the water pump 503 to rotate. The water pump 503 draws the acid solution from the soaking tank 4 through the connecting pipe 504. After being filtered by the filter box 509 and the filter disc 510, the acid solution is discharged from the output end of the water pump 503, then enters the diversion plate 506 through the output pipe 505, and finally is evenly sprayed onto the guardrail panel in the soaking tank 4 by the spray pipe 507 and the spray column 508, thus performing acid washing treatment on the guardrail panel. The acid solution is recycled, improving efficiency and reducing waste.

[0034] like Figures 1-5 As shown, this invention illustrates an acid pickling device for highway guardrail production and processing in another embodiment of the present invention, comprising: a stirring device 9 disposed on the side of an immersion tank 4; the stirring device 9 includes a transmission plate 901; a transmission column 902 is rotatably connected through and to the side of the transmission plate 901; a bevel gear 903 is fixedly connected to one end of the transmission column 902; a bevel gear 904 is fixedly connected to the end of a dual-shaft motor 502 away from the water pump 503; and a stirring wheel 905 is fixedly connected to the end of the transmission column 902 away from the bevel gear 903. A pulley 906 is fixedly connected to the circumferential surface of the immersion tank 4. A secondary shaft 907 is rotatably connected through the side of the immersion tank 4. A secondary stirring wheel 908 is fixedly connected to one end of the secondary shaft 907. A pulley 909 is fixedly connected to the other end of the secondary shaft 907 away from the secondary stirring wheel 908. A transmission belt 910 is provided on the circumferential surface of the pulley 909. The pulley 906 and the pulley 909 are connected by the transmission belt 910. The function of the belt 906 is to make the acid solution uniformly stirred in the immersion tank 4, accelerate the pickling process, improve the surface treatment effect of the guardrail, and ensure stable product quality.

[0035] In some examples, a protective box 10 is fixedly connected to the side of the fixed base plate 1. The top of the protective box 10 is provided with an oil drip hole 11, which is used to protect the bevel gear 1 903 and bevel gear 2 904 from acid corrosion, extend the service life of the equipment, and ensure the stable operation of the transmission system.

[0036] The circumferential surface of the transmission column 902 penetrates the side of the protective box 10. The first bevel gear 903 and the second bevel gear 904 are located inside the protective box 10. Their function is to isolate the acid, prevent gear wear, improve transmission efficiency, and ensure long-term stable operation of the equipment.

[0037] The circumferential surface of the transmission column 902 penetrates the side of the soaking tank 4, and the circumferential surface of the secondary shaft 907 also penetrates the side of the soaking tank 4. Their function is to ensure a tight connection between the transmission system and the soaking tank 4, reduce the risk of acid leakage, and at the same time ensure the efficient operation of the stirring device 9.

[0038] The first bevel gear 903 and the second bevel gear 904 mesh with each other. The second bevel gear 904 has fewer teeth than the first bevel gear 903. Its function is to reduce speed and increase torque output, thus ensuring appropriate stirring force.

[0039] For example, such as 1~ Figure 5 As shown, during operation, the dual-shaft motor 502 not only drives the water pump 503 to circulate and spray acid, but also transmits power from its other end to the first bevel gear 903 via the second bevel gear 904. Since the second bevel gear 904 has fewer teeth than the first bevel gear 903, this gear ratio design increases the rotational speed of the first bevel gear 903. The rotation of the first bevel gear 903 drives the transmission column 902 to rotate, which in turn drives the stirring wheel 905 to stir the acid solution in the soaking tank 4. Simultaneously, the pulley 906 on the transmission column 902 is connected to the second pulley 909 on the secondary shaft 907 via the transmission belt 910, achieving synchronous power transmission and causing the secondary stirring wheel 908 to rotate synchronously, further enhancing the stirring effect.

[0040] 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.
