Description

Technical Field

[0001] This invention relates to a multi-purpose integrated on-site metallographic preparation reagent bottle, belonging to the field of metallographic testing technology. Background Technology

[0002] On-site metallography refers to the on-site metallographic inspection technique that observes the metallographic structure on the workpiece. This inspection method does not require cutting and sampling. The workpiece is directly ground, polished, and etched before being observed under a microscope. It has been widely used in industries such as boiler inspection institutes (special inspection institutes), power plants, electric power research institutes, chemical industry, aviation, shipbuilding, and steam turbines.

[0003] In the power plant industry, on-site metallographic inspection is also an important testing method for assessing high-temperature damage to heated pipes and other metal materials, creep damage assessment, aging rating, grain size rating, and non-metallic inclusion rating.

[0004] Metallographic testing mainly consists of four steps: grinding, polishing, etching, and observation. Polishing and etching require the selection of appropriate polishing paste (liquid) and etching agent depending on the material. Therefore, during on-site metallographic inspection, it is necessary to bring not only grinding and polishing equipment, sandpaper of different sizes, and a metallographic microscope, but also various items such as a water spray bottle, an alcohol / acetone spray bottle, polishing paste, etching agent, and beakers, cotton, and tweezers, depending on the material being tested.

[0005] However, metallographic inspection of the boiler's heating surface tubes often involves working at heights, overlapping operations, and confined space work. On-site metallographic testing is frequently conducted on scaffolding platforms, lifting platforms, or suspended baskets, often in dark, dusty, and harsh environments. Working at heights poses significant risks to inspectors carrying heavy workloads, as numerous testing equipment and tools are prone to falling objects. The lack of light or insufficient illumination in confined spaces such as boilers can easily lead to the misuse of polishing pastes and etching agents, and the dusty environment can negatively impact the metallographic etching results. Summary of the Invention

[0006] The purpose of this invention is to provide a multi-purpose integrated on-site metallographic preparation reagent bottle to solve the problems mentioned in the background art.

[0007] The technical solution of the present invention is as follows:

[0008] A multi-purpose integrated on-site metallographic preparation reagent bottle includes an integrated liquid nozzle end and an etchant roller end:

[0009] The liquid nozzle end includes a nozzle and a liquid cavity connected to the nozzle;

[0010] The corrosive roller end includes a lifting assembly, a press-type corrosive device mounted on the lifting assembly, and a corrosive roller mounted on the liquid outlet end of the corrosive device.

[0011] Preferably, the nozzle includes an alcohol nozzle and a water nozzle, the liquid cavity includes an alcohol cavity and a water cavity, the alcohol nozzle is connected to the alcohol cavity, and the water nozzle is connected to the water cavity.

[0012] Preferably, it also includes a nozzle protective cover for enclosing the alcohol nozzle and the water nozzle.

[0013] Preferably, the nozzle button A of the alcohol nozzle is designed differently from the nozzle button B of the water nozzle.

[0014] Preferably, it also includes an empty compartment end integrated with the liquid nozzle end and the corrosive roller end, the empty compartment end including an empty compartment drawer and a storage drawer movably disposed within the empty compartment drawer.

[0015] Preferably, the etchant device includes etchant device A and etchant device B, and the etchant rollers include etchant A roller and etchant B roller. The etchant device A and etchant A roller are correspondingly matched, and the etchant device B and etchant B roller are correspondingly matched.

[0016] Preferably, the corrosive device includes a corrosive cavity and a liquid outlet installed at the outlet of the corrosive cavity. The liquid outlet is provided with a rotating groove, and the corrosive roller is detachably engaged with the rotating groove and rotatedly cooperates with it.

[0017] Preferably, the liquid outlet head is equipped with a rotary joint and a hollow shaft. The hollow shaft is connected to the output end of the rotary joint. The hollow shaft is arranged parallel to the corrosive roller. The hollow shaft has several overflow holes that are spirally distributed around its axis.

[0018] The hollow shaft has a first tooth installed at one end, and the corrosive roller has a second tooth installed at the end that meshes with the first tooth.

[0019] Preferably, the corrosive roller is detachably mounted on the outer wall of the rotating shaft, the second tooth is detachably mounted on the end of the rotating shaft, and the rotating shaft is detachably engaged with and rotatably fitted to the rotating slot.

[0020] Preferably, the lifting assembly includes a lifting gear and a rack that mesh with each other, the rack being fixedly connected to the corrosive agent device, and a roller lifting knob being installed on the lifting gear.

[0021] The present invention has the following beneficial effects:

[0022] The consumables needed for on-site metallographic inspection, such as purified water, alcohol or acetone, different grades of sandpaper and polishing paste (agent), and metallographic etchant, are integrated into a multi-purpose on-site metallographic preparation reagent bottle. The integrated liquid nozzle and etchant roller allow for spraying and wiping in a misting manner, replacing traditional methods of pouring and squeezing, thus saving on-site reagent usage. The alcohol and water nozzles are designed differently, making it easy to distinguish the press nozzle in dark environments and preventing accidental spraying.

[0023] The empty compartment is designed to be replaceable according to the actual needs of on-site metallographic testing. It can store different types of sandpaper, grinding heads and polishing paste, and can be placed in different empty compartments according to the type to prevent the sandpaper, grinding heads and polishing paste of the same type from being lost or used incorrectly on site.

[0024] The on-site metallographic etching process utilizes a brush roller instead of the traditional method of using tweezers to hold cotton and applying the etchant in a beaker or bottle. The etchant roller is designed with multiple rollers to allow selection of appropriate etchants for different metal materials on-site for metallographic etching and observation. To prevent personal injury, environmental contamination, and cross-contamination of the etchant, a rotating and lifting design is employed. The roller lifting knob features a differentiated design to prevent incorrect application of etchant in dark environments. Furthermore, the etchant roller is detachable for cleaning and replacement.

[0042] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0043] Example 1: As Figure 1-9 As shown:

[0044] like Figure 1 , 2 As shown in Figures 8 and 9, the reagent bottle includes an integrally connected liquid nozzle end 1, empty chamber end 2, and corrosive roller end 3. The empty chamber end 2 is located in the middle of the reagent bottle, while the liquid nozzle end 1 and the corrosive roller end 3 are located at opposite ends of the reagent bottle. The reagent bottle has an overall cylindrical structure, making it convenient to carry and operate with one hand.

[0045] The liquid nozzle end 1 includes a press-type alcohol nozzle 11 and a water nozzle 12, as well as an alcohol chamber 14, a water chamber 15, and a nozzle protective cap 13. The alcohol nozzle 11 is connected to the alcohol chamber 14, and the water nozzle 12 is connected to the water chamber 15. The alcohol chamber 14 is used to hold alcohol, and the water chamber 15 is used to hold purified water. The nozzle protective cap 13 is detachably threaded to the reagent bottle. The nozzle button A16 of the alcohol nozzle 11 and the nozzle button B17 of the water nozzle 12 have different designs to prevent accidental use of the reagent in dark environments. At the same time, the ratio of the water chamber 15 to the alcohol chamber 14 is 6:4. The protective cap 13 provides drop protection, waterproofing, and dustproofing for the alcohol nozzle 11 and the water nozzle 12.

[0046] like Figure 2 , 6 As shown, the empty compartment 2 includes an empty compartment drawer 21, a storage drawer A22, and a storage drawer B23; and the different storage drawers A22 and B23 have differentiated designs to prevent misuse in dark environments. Both storage drawers A22 and B23 have limiting grooves 24; a limiting block 25 is fixedly installed inside the empty compartment drawer 21, and the limiting block 25 slides linearly within the corresponding limiting groove 24. Storage drawers A22 and B23 are used for different types of sandpaper, grinding heads, polishing paste, etchant A roller 35, and etchant B roller 36, etc.

[0047] like Figure 1-5 As shown in Figure 7, the etchant roller end 3 includes an etchant device A31 and an etchant device B32; the etchant device A31 includes a roller lifting knob A33, an etchant A roller 35, an A lifting gear 37, and an etchant A cavity 39; the etchant device B32 includes a roller lifting knob B34, an etchant B roller 36, a B lifting gear 38, and an etchant B cavity 40; the etchant A roller 35 and the etchant B roller 36 adopt a rough roller structure; the roller lifting knob A33 and the roller lifting knob B34 have a differentiated design to avoid misuse of etchant in dark environments and improve the safety and accuracy of on-site testing;

[0048] Roller lifting knobs A33 and B34 are rotatably connected to the outside of the reagent bottle. The inner end of roller lifting knob A33 is fixedly connected to lifting gear A37, and the inner end of roller lifting knob B34 is fixedly connected to lifting gear B38. Corrosive agent cavity A39 and corrosive agent cavity B30 are both fixed with corresponding lifting racks on their side walls. Lifting gear A37 at the inner end of roller lifting knob A33 meshes with the lifting rack of corrosive agent cavity A39, and lifting gear B38 at the inner end of roller lifting knob B34 meshes with the lifting rack of corrosive agent cavity B30. Thus, the rotation of roller lifting knobs A33 and B34 drives lifting gears A37 and B38 to rotate, and the rotation of lifting gears A37 and B38 drives the corresponding corrosive agent cavity A39 and corrosive agent cavity B40 to rise and fall through the meshing lifting racks.

[0049] like Figure 3-5 As shown, the raising and lowering of corrosive agent A cavity 39 / corrosive agent B cavity 40 allows the corrosive agent A roller 35 / corrosive agent B roller 36 at their outlet to enter and exit the inner cavity at the end of the reagent bottle. This is to prevent the corrosive agent from causing harm to the human body, and at the same time to facilitate storage and carrying.

[0050] Corrosive device A31 and corrosive device B32 operate on the same press-spray principle. By raising and lowering corrosive device A31 / corrosive device B3, corrosive A roller 35 / corrosive B roller 36 are moved out of the inner cavity at the end of the reagent bottle. Then, by pressing corrosive A roller 35 / corrosive B roller 36, the corrosive agent in corrosive A cavity 39 / corrosive B cavity 40 is dropped out under the action of gravity, wetting corrosive A roller 35 / corrosive B roller 36. At the same time, corrosive A roller 35 / corrosive B roller 36 roll and wipe the metal to be corroded to achieve the purpose of corrosion.

[0051] Meanwhile, the water, alcohol, and corrosive agent are allocated according to the amount of reagents required for on-site metallographic testing, with a pure water volume: alcohol volume: corrosive agent volume ratio of 6:4:0.5.

[0052] The integrated design eliminates the need to carry a large number of items for on-site metallographic examinations, packaging all necessary consumables into a single unit. The press-type spray nozzle helps conserve reagents.

[0053] Furthermore, to adapt to light-free environments, the alcohol spray nozzle 11, water spray nozzle 12, storage drawer A22, storage drawer B23, roller lifting knob A33, and roller lifting knob B34 are all differentiated designs.

[0054] Example 2: Contains all the contents of Example 1, except that, as Figure 10-11 As shown:

[0055] When the lengths of the corrosive A roller 35 and the corrosive B roller 36 are relatively long, the corrosive agent falling from the outlet head 51 tends to be concentrated and cannot be evenly dripped onto the corrosive A roller 35 and the corrosive B roller 36.

[0056] The outlets at the bottom of the corrosive agent A cavity 39 and the corrosive agent B cavity 40 are equipped with corresponding outlet heads 51. A rotary joint 52 is installed inside the outlet head 51. A flow channel 511 is formed inside the outlet head 51, with its lower end connected to one end of the rotary joint 52 and its upper end extending into the interior of the corrosive agent A cavity 39 and the corrosive agent B cavity. A hollow shaft 53 is rotatably connected inside the outlet head 51, with one end of the hollow shaft 53 connected to the other end of the rotary joint 52. A first tooth 54 is installed at the end of the hollow shaft 53. Figure 4 , 10 As shown, the bottom of the dispensing head 51 has two elastic rotating slots 512 at both ends, and the end of the rotating shaft 55 is detachably equipped with a second tooth 551; the rotating shaft 55 can be engaged into the rotating slot 512, at which time the first tooth 54 and the second tooth 551 mesh, and the hollow shaft 53 is parallel to the axis of the rotating shaft 55; and the rotating shaft 55 can rotate within the rotating slot 512. Since the corrosive agent A roller 35 / corrosive agent B roller 36 are consumables, the corrosive agent A roller 35 / corrosive agent B roller 36 can be detachably installed on the outer wall of the rotating shaft 55. An elastic element 56 is installed between the bottom of the dispensing head 51 and the corresponding corrosive agent A cavity 39 / corrosive agent B cavity 40.

[0057] like Figure 11 As shown, the hollow shaft 53 has multiple overflow holes 531 on its outer wall, which are spirally distributed around the axis of the hollow shaft 53. The corrosive agent inside the hollow shaft 53 falls out from the bottom overflow holes 531 under gravity, landing on the corrosive agent A roller 35 / corrosive agent B roller 36 directly below. Under normal conditions, the elastic force of the elastic element 56 causes the outlet head 51 to move away from the corrosive agent A cavity 39 / corrosive agent B cavity 40. At this time, the upper end of the flow channel 511 inside the outlet head 51 is in a closed state, as shown... Figure 10 As shown;

[0058] When the etchant A roller 35 / etchant B roller 36 comes into contact with and presses against the metal to be etched, the upper end of the flow channel 511 is in an open state, and the etchant in the inner cavity of the etchant A cavity 39 / etchant B cavity 40 flows from the flow channel 511 into the rotary joint 512, and then into the inner cavity of the hollow shaft 53.

[0059] When the corrosive agent A roller 35 / corrosive agent B roller 36 rolls and wipes the metal to be corroded, the hollow shaft 53 is rotated by the meshing of the first tooth 54 and the second tooth 551. The rotation of the hollow shaft 53 causes the overflow holes 531 at different locations to rotate to the bottom, so that the corrosive agent in the hollow shaft 53 can be evenly sprinkled on the outer wall of the corrosive agent A roller 35 / corrosive agent B roller 36.

[0060] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
