Description

Technical Field

[0001] This utility model relates to the technical field of low-magnification rinsing devices, specifically to a low-magnification rinsing device for preventing splashing on the surface of a sample. Background Technology

[0002] Low-temperature hot pickling is a method that uses high-temperature acid solutions to remove oxide scale and rust from the surface of steel for observing the macrostructure and defects of metallic materials.

[0003] Currently, quality inspection departments and research institutions in industries such as machinery and metallurgy use traditional hot pickling methods. They use acid-resistant containers as pickling vessels, inject hydrochloric acid, and then heat the steel billets to pickle them. After pickling, the samples need to be transferred to other containers for cleaning and drying.

[0004] After rinsing with the nozzle, residual cleaning fluid drips from the nozzle, causing liquid splashing and contaminating the sample inspection surface. This situation increases the difficulty of image acquisition and evaluation, reduces the efficiency of low-magnification inspection, and increases the difficulty of inspection. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a low-magnification rinsing device for preventing sample surface contamination, comprising:

[0006] Box body; spray pipe, the spray pipe is horizontally installed on the inner wall of the box body, the bottom surface of the spray pipe is provided with nozzles, one end of the spray pipe passes through the box body and is connected to the external acid storage tank;

[0007] A horizontal conduit is installed below the spray pipe along the direction of the spray pipe. The top surface of the horizontal conduit has an opening for collecting residual liquid from the nozzle. One end of the horizontal conduit passes through the box and connects to an external recycling tank.

[0008] Furthermore, it also includes: a sample stage, with multiple sample stages mounted on the bottom surface of the housing.

[0009] Furthermore, the bottom of the box also has a drain hole, which is connected to an external recycling tank.

[0010] Furthermore, there are gaps between the plurality of sample stages.

[0011] Furthermore, it also includes: a base, the upper end face of which is connected to the lower end face of the box body, one end of which is higher than the other end, thereby causing the lower end face of the box body to tilt toward the drain hole.

[0012] Furthermore, it also includes: a lid, which is hinged to the upper edge of the side wall of the box.

[0013] Furthermore, the side wall of the box also has an overflow hole, which is connected to an external recycling tank.

[0014] Furthermore, an acid drainage pipe is also installed on the side wall of the box.

[0015] Furthermore, the side wall of the box is also equipped with an exhaust vent, which is connected to an external exhaust fan.

[0016] Furthermore, the exhaust vent is positioned higher than the overflow hole.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. This utility model, through the design of a horizontal conduit below the nozzle, can directly collect the residual liquid after the nozzle rinsing is completed, fundamentally solving the problem of secondary contamination of the sample surface caused by nozzle dripping in traditional rinsing devices.

[0019] 2. The cover and exhaust system effectively control the spread of acid mist, improve the working environment, and the closed design reduces the leakage of harmful gases, protecting the health of operators. Attached Figure Description

[0022] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0023] like Figure 1 As shown, a low-magnification rinsing device for preventing sample surface contamination includes:

[0024] The box body 1 has a drain hole 11 at its bottom, which connects to an external recycling tank. The side wall of the box body 1 also has an overflow hole 12, which connects to the external recycling tank. A vent 13 is also installed on the side wall of the box body 1, which connects to an external exhaust fan. The vent 13 is positioned higher than the overflow hole 12.

[0025] Spray pipe 2, which is horizontally installed on the inner wall of the box 1, has a nozzle 21 on its bottom surface, and one end of the spray pipe 2 passes through the box 1 and is connected to the external acid storage tank.

[0026] A horizontal conduit 3 is installed below the spray pipe 2 along the direction of the spray pipe 2. The top surface of the horizontal conduit 3 has an opening 31, which is located directly below the nozzle 21. The opening 31 is used to collect the residual liquid of the nozzle 21. One end of the horizontal conduit 3 passes through the box body 1 and is connected to the external recycling tank.

[0027] Sample stages 4, multiple sample stages 4 are mounted on the bottom surface of the housing 1. Gaps exist between the multiple sample stages 4 to allow free flow of acid and prevent liquid accumulation between the sample stages.

[0028] The base 5 has its upper end face connected to the lower end face of the box body 1. One end of the base 5 is higher than the other end, so that the lower end face of the box body 1 is tilted toward the drain hole 11.

[0029] The cover 6 is hinged to the upper edge of the side wall of the box 1.

[0030] Acid drain pipe 7 is installed on the side wall of the box body 1.

[0031] The usage method is as follows: At the beginning of the low-magnification rinsing experiment, plug the drain hole 11 with the matching plug to prevent leakage. Place the sample on the sample stage 4 and cover it with the cover 6 to ensure experimental safety and prevent acid mist leakage during rinsing. Spray the acid solution onto the sample through the spray pipe 2 via an external acid storage tank (usually hydrochloric acid, which is used as the rinsing solution for the low-magnification rinsing experiment) and a pressurization device. Turn on the external exhaust fan and remove the acid mist through the exhaust port 13 to prevent contamination of the sample. The overflow hole 12 is used to prevent the liquid level from being too high and causing acid solution to flow into the exhaust port 13. After the low-magnification rinsing experiment is completed, the residual acid solution on the nozzle 21 drips into the horizontal guide tube 3 and flows into the external recovery tank. Figure 2 As shown, remove the plug on the drain hole 11. Since the lower end of the box 1 is tilted towards the drain hole 11, the acid in the box 1 flows into the external recovery tank through the drain hole 11. Alternatively, the acid in the box 1 can be poured out directly through the acid drain pipe 7. Open the cover 6 and use a special clamping tool to remove the sample. When cleaning the box 1, the cleaning solution can also be poured out through the acid drain pipe 7.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit its protection scope. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that after reading this utility model, they can still make various changes, modifications or equivalent substitutions to the specific implementation of the utility model, but these changes, modifications or equivalent substitutions are all within the protection scope of the pending claims of the utility model.
