Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a rinsing device for acid washing tests and a method for modifying it. Background Technology

[0002] During shipbuilding, a large number of samples need to undergo physical and chemical tests. These tests include pickling to expose weld areas, and other procedures such as impact testing in mechanical testing and macroscopic testing in metallographic examination.

[0003] Pickling is a process that uses an acid solution (or a corrosive agent) to rinse a sample. In the existing technology, a tap is usually connected to an acid solution storage tank. The sample to be pickled is placed under the tap, the water flow is turned on, and the acid solution rinses the sample below, thus completing the pickling step.

[0004] The shortcomings of existing pickling equipment include: when there are a large number of test samples, the samples to be pickled can only be moved under the water tap in turn, which is labor-intensive and has low pickling efficiency; during the process of adjusting the position of the samples, the samples may collide and splash acid solution, which poses a safety hazard. Summary of the Invention

[0005] The purpose of this invention is to propose a rinsing device for acid washing tests and its modification method, which solves the problem of low acid washing efficiency of existing acid washing devices and makes them more convenient to use.

[0006] To achieve this objective, the present invention employs the following technical solution:

[0007] A rinsing device for acid pickling tests includes: a liquid outlet bend for discharging acid solution; a base including an inlet and an outlet, the inlet being connected to an acid solution reservoir, the outlet being positioned above or below the base by adjusting the installation direction of the base, the liquid outlet bend being detachably connected to the outlet; and an extension tube detachably connected between the liquid outlet bend and the outlet to increase the liquid outlet coverage area of ​​the liquid outlet bend.

[0008] In one preferred embodiment, the liquid outlet bend is provided with a protrusion, and the acid washing test rinsing device further includes a bracket with a support groove. When the liquid outlet bend is connected to the liquid outlet through the extension tube, the protrusion can be placed in the support groove to support the liquid outlet bend.

[0009] In one preferred embodiment, the protrusions are symmetrically arranged on both sides of the liquid outlet bend, and the rinsing device for acid washing test includes two symmetrically arranged supports, each of which has a support groove, and the liquid outlet bend is located between the two supports.

[0010] In one preferred embodiment, the bracket is fixedly connected to the base.

[0011] In one preferred embodiment, both the protrusion and the supporting groove are cubic in shape, and the lateral width of the supporting groove is greater than the lateral width of the protrusion.

[0012] In one preferred embodiment, the edges of the bump are rounded and deburred.

[0013] In one preferred embodiment, the protrusion is closer to the end of the outlet bend that connects to the extension pipe than to the outlet end of the outlet bend.

[0014] In one preferred embodiment, the inner and / or outer sides of the liquid outlet bend, the base, and / or the extension tube are provided with an acid corrosion resistant layer.

[0015] In one preferred embodiment, the extension tube is a flexible metal tube made of stainless steel.

[0016] On the other hand, the present invention adopts the following technical solution:

[0017] A method for modifying the rinsing device for acid pickling tests involves removing the outlet bend from the base, inverting the base so that its outlet is located below the base, connecting one end of an extension tube to the outlet bend, and connecting the other end of the extension tube to the outlet of the base.

[0018] The acid washing test rinsing device disclosed in this invention includes a detachably connected outlet bend, a base, and an extension tube. By adding the extension tube, the outlet coverage of the outlet bend can be increased. When there are many samples to be acid washed, the user can hold the outlet bend and move it within a certain range, and the acid solution will be sprayed onto the samples to be acid washed in sequence, making it more convenient to use and reducing labor intensity. Samples that originally needed to be acid washed in batches can be completed at one time, shortening the acid washing time, increasing acid washing efficiency, and reducing the amount of acid solution used. There is no need to move the samples frequently, and the user can change the outlet direction by adjusting the angle of the outlet bend to avoid the liquid splashing towards the user, making it safer to use and more practical.

[0019] The present invention discloses a method for modifying a rinsing device for acid pickling tests, which can modify the existing detachable liquid outlet device between the faucet and the base without completely replacing the existing liquid outlet device, making it more convenient to use; only an extension tube needs to be added to increase the acid pickling range, with low modification cost and good user experience.

[0033] This embodiment discloses a rinsing device for acid washing tests and a method for modifying it, such as... Figure 1 and Figure 2 As shown, the rinsing device for acid washing test includes an outlet bend 1 for discharging acid solution, a base 2 for connecting to an acid solution reservoir, and an extension pipe 3 that can be detachably connected between the outlet bend 1 and the base 2. The base 2 includes an inlet and an outlet. The inlet is connected to the acid solution reservoir. By adjusting the installation direction of the base 2, the outlet can be positioned above or below the base 2.

[0034] The rinsing device includes two methods of use, such as... Figure 1 As shown, one method involves directly and detachably connecting the outlet bend 1 to the outlet without using the extension tube 3. When the number of samples for the acid washing test is small, the samples are placed directly below the outlet end of the outlet bend 1, allowing the water flow to directly rinse the samples, resulting in good cleaning effect and a small space occupied by the rinsing device.

[0035] like Figure 2As shown, another method is to use an extension tube 3, which is detachably connected between the outlet bend 1 and the outlet. The extension tube 3 has a certain length and can be bent and twisted at will, thereby increasing the coverage area of ​​the outlet bend 1. When there are many samples in the acid washing test, the user can hold the outlet bend 1 and move it within a certain range, and the acid solution will be sprayed onto the samples to be acid washed in sequence, which is more convenient to use and reduces labor intensity; samples that originally needed to be acid washed in batches can be completed at one time, shortening the acid washing time, increasing acid washing efficiency, and reducing the amount of acid solution used; there is no need to move the samples frequently, and the user can change the direction of the liquid discharge by adjusting the angle of the outlet bend 1 to avoid the liquid splashing towards the user, making it safer to use and more practical.

[0036] The rinsing device can be a specially manufactured independent outlet bend 1, base 2, and extension pipe 3, assembled according to usage requirements; or it can be a modification of an existing detachable outlet device between the faucet and the base. Specifically, the modification method for this acid pickling test rinsing device is as follows: remove the outlet bend 1 from the base 2, invert the base 2 so that its outlet is located below the base 2; prepare an extension pipe 3 of suitable length and flexibility, connect one end of the extension pipe 3 to the outlet bend 1, and connect the other end of the extension pipe 3 to the outlet of the base 2. It is understood that when there is an upper section of water pipe connecting the outlet bend 1 and the base 2, the upper section of water pipe needs to be removed simultaneously when disassembling the outlet bend 1.

[0037] Based on the above structure, such as Figures 3 to 5 As shown, the rinsing device for acid washing also includes a bracket 21, on which a support groove 22 is provided, and a protrusion 11 is provided on the outlet bend 1. When the outlet bend 1 is connected to the outlet through the extension tube 3 and there is no need to move the outlet bend 1, the protrusion 11 can be placed in the support groove 22. At this time, the outlet bend 1 can be a closed device, with no sample to be acid-washed; or the outlet bend 1 can be an open device, with the acid solution only acid-washing the sample located below the outlet end of the outlet bend 1, making it easier to use. The support groove 22 can support and limit the protrusion 11, thereby realizing the support of the bracket 21 for the outlet bend 1, eliminating the need to continuously hold the outlet bend 1 or place it arbitrarily, making it more convenient to use.

[0038] The specific number of protrusions 11 and supporting grooves 22 is sufficient to support the outlet bend 1. In this embodiment, the rinsing device for acid washing tests includes two symmetrically arranged supports 21, each support 21 having a supporting groove 22. Protrusions 11 are symmetrically arranged on both sides of the outlet bend 1. In use, the outlet bend 1 is located between the two supports 21, and the two supports 21 simultaneously support the outlet bend 1 from both sides, making the spatial posture of the outlet bend 1 more stable and preventing acid solution from splashing due to the shaking of the outlet bend 1, thus making it safer to use.

[0039] The specific location of the bracket 21 is not limited, as long as it can stably support the liquid outlet bend 1. In this embodiment, the bracket 21 is fixedly connected to the base 2, making it more convenient to use. The bracket 21 and the base 2 can be integrally formed, resulting in high strength and strong load-bearing capacity; the bracket 21 and the base 2 can also be processed separately and then welded or riveted to form an integral structure, which is convenient for processing, has low manufacturing cost, and high processing efficiency.

[0040] The specific shapes of the protrusion 11 and the supporting groove 22 are not limited, as long as the protrusion 11 can be easily and stably embedded in the supporting groove 22. In this embodiment, both the protrusion 11 and the supporting groove 22 are cubic in shape. The vertical walls on both sides of the supporting groove 22 can act as a barrier against the protrusion 11, preventing the protrusion 11 from accidentally falling out of the supporting groove 22, thus making it safer to use. The lateral width of the supporting groove 22 is greater than the lateral width of the protrusion 11, allowing the protrusion 11 to be smoothly inserted into and removed from the supporting groove 22, resulting in a better user experience.

[0041] To prevent users' fingers from being cut when holding the device, the edges of the protrusion 11 are rounded and deburred. The specific angle of the rounding is not limited; the goal is to minimize the rounding angle while avoiding cuts to the user, thereby improving processing efficiency and reducing processing difficulty. The specific method for deburring is not limited; any existing method that can smooth the edges of the protrusion 11 can be used. The degree of smoothness of the edges of the protrusion 11 is not limited; it is sufficient that it does not harm the user's fingers and provides a comfortable feel.

[0042] The specific location of the protrusion 11 on the outlet bend 1 is not limited, as long as it allows the bracket 21 to stably support the outlet bend 1. In this embodiment, the protrusion 11 is closer to the end of the outlet bend 1 connecting to the extension tube 3 than to the outlet end of the outlet bend 1. That is, the protrusion 11 is located near the bottom of the outlet bend 1, so it does not affect the user's ability to hold the middle or lower part of the outlet bend 1. The user is not affected by the protrusion 11 when moving the outlet bend 1, making it more convenient to use.

[0043] The specific composition and ratio of the acid solution are not limited; any reagents available in the prior art capable of corroding samples used in shipbuilding can be used. To extend the service life of the rinsing device, an acid-resistant corrosion-resistant layer is provided on the inner and / or outer sides of the outlet bend 1, base 2, and / or extension pipe 3. The specific materials used to prepare the acid-resistant corrosion-resistant layer are not limited and can be adjusted according to the composition and ratio of the acid solution, as long as it can prevent corrosion of the inner and / or outer sides of the outlet bend 1, base 2, and / or extension pipe 3.

[0044] The specific shape and material of the extension tube 3 are not limited, as long as it can increase the liquid outlet coverage of the outlet bend 1. In this embodiment, the extension tube 3 is a flexible metal tube made of 304 stainless steel. The specific size of the flexible metal tube is not limited; in this embodiment, the inner diameter is 25mm ± 1mm ​​and the outer diameter is 29mm ± 1mm.

[0045] The specific connection method between the extension tube 3 and the outlet bend 1 and the base 2 is not limited, as long as it can prevent acid solution leakage. Sealing rings can be installed between the extension tube 3 and the outlet bend 1, and between the extension tube 3 and the base 2, to completely fill the gaps at the connection points and prevent acid solution leakage. When it is not necessary to disassemble the extension tube 3, one end of the extension tube 3 can be welded to the outlet bend 1 and the other end to the base 2, which provides better leak prevention and safer use.

[0046] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
