Description

Technical Field

[0001] This utility model relates to the field of chemical instrument testing technology, specifically to a chemical instrument corrosion resistance testing device. Background Technology

[0002] Chemical instruments are used to automatically detect, display, and control various variables (such as temperature, pressure, liquid level, flow rate, composition, etc.) in chemical, oil refining, and other production processes. They are widely used in the production processes of chemical, oil refining, petrochemical, pharmaceutical, food, and environmental protection industries to achieve automated monitoring, control, and optimization of the production process, thereby improving production efficiency, product quality, and safety. However, chemical instruments used in chemical environments for extended periods may experience corrosion. Therefore, instruments used in chemical environments have certain standards for corrosion resistance. Currently, existing instruments generally undergo random corrosion resistance testing after leaving the factory to ensure a pass rate.

[0003] For example, utility model patent CN221260748U discloses a chemical instrument corrosion resistance testing device, including: an operating cabinet, a test platform, a collection hopper, an installation box, a liquid collection box, a water pump, and a storage box; the storage box is installed above the operating cabinet, the test platform is installed inside the operating cabinet, the collection hopper is arranged below the test platform, the installation box extends through the collection hopper, the liquid collection box is installed inside the installation box, a reflux head is arranged on the liquid collection box, the installation box, and the operating cabinet, one end of the reflux head extends into the liquid collection box, the other end of the reflux head is connected to the input end of the water pump through a pipe, the output end of the water pump is connected to the storage box through a pipe, and the water pump is used to transport the chemical reagents inside the liquid collection box to the storage box.

[0004] While the aforementioned devices can detect the corrosion resistance of chemical instruments without direct contact and can recycle chemical reagents, they are similar to most existing chemical instrument corrosion resistance testing devices. They place the chemical instrument in a closed testing environment, spray chemical reagents onto it, and determine corrosion resistance by observing the severity of corrosion. However, after testing, some chemical reagents remain on the instrument, making it inconvenient to remove it directly. Furthermore, the chemical reagents can obscure the surface of the instrument, hindering observation. Therefore, we provide a chemical instrument corrosion resistance testing device. Utility Model Content

[0005] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a chemical instrument corrosion resistance testing device.

[0006] In a first aspect, this application provides a chemical instrument corrosion resistance testing device, comprising a housing, wherein a lower partition and an upper partition are connected sequentially from bottom to top at the center of the housing, forming a rectangular opening between the lower partition and the upper partition, a support rod is rotatably connected to the top of the lower partition at the rectangular opening, and support rings with a height less than the width of the rectangular opening are connected to both ends of the support rod, a filter plate is installed inside the support rings, a spraying mechanism is respectively provided on both sides of the lower partition on the outside of the housing, a rotating mechanism is provided at the center of the top of the support rod, a protective mechanism is provided on the outside of the upper partition, a spring mechanism is provided at the top of the protective mechanism, and an open upper half of one side wall of the housing parallel to the upper partition is open and a closed door is hinged inside the open.

[0007] This feature divides the interior of the housing into two independent spaces, allowing for separate chemical testing and cleaning operations on the chemical instruments within each space.

[0008] According to the technical solution provided in the embodiments of this application, the spraying mechanism includes a circulation pipe whose bottom end is connected to the interior of the lower end of the housing. The circulation pipe is fixedly connected to the outer wall of the housing. The upper end of the circulation pipe is connected to a nozzle facing the support ring on the same side. A water pump is fixedly installed on the outer wall of the housing in the middle of the circulation pipe.

[0009] This feature allows for the spraying of corresponding chemical reagents or purified water onto chemical instruments placed on the support ring via a nozzle, enabling the testing or cleaning of these instruments.

[0010] According to the technical solution provided in the embodiments of this application, the rotating mechanism includes a connecting rod whose bottom end is fixedly connected to the support rod at the center. The connecting rod is vertically rotatably engaged inside the upper partition and its top end penetrates the top side wall of the housing. A rotating disk is connected to the top of the connecting rod.

[0011] This design allows the two support rings to be interchanged with the cooperation of the rotating mechanism and the support rod, thus facilitating the rotation of the support rings and improving the efficiency of chemical instrument testing.

[0012] According to the technical solution provided in the embodiments of this application, the protective mechanism includes two protective plates that are symmetrically slidably clamped on both sides of the upper partition. A notch for accommodating the support rod is opened at the center of the lower end of the protective plate. Two sliding rods are connected to the top of each protective plate.

[0013] According to the technical solution provided in the embodiments of this application, the sliding rod is slidably inserted into the top side wall of the housing, and a rectangular plate is connected between the two sliding rods on the same side of the two protective plates outside the top of the housing.

[0014] These two settings facilitate the isolation and protection of the rectangular opening between the upper and lower partitions, and also limit the position of the rotated support rod, making it easier to position the spraying mechanism and prevent spraying deviation.

[0015] According to the technical solution provided in the embodiments of this application, the elastic mechanism includes two opposing fixed plates in the shape of an inverted L. The bottom end of the fixed plate is fixedly connected to the rectangular plate on the same side, and a pull rod is installed between the upper horizontal sections of the two fixed plates.

[0016] According to the technical solution provided in the embodiments of this application, the elastic mechanism further includes a tension spring, the bottom end of which is connected to the top surface of the housing, and the top end of which is connected to the bottom surface of the horizontal section of the fixing plate;

[0017] According to the technical solution provided in the embodiments of this application, the height of the notch at the bottom of the protective plate is greater than the width of the rectangular opening between the lower partition and the upper partition. When the rectangular plate is pressed tightly against the top surface of the housing and the support rod is stuck in the corresponding notch, the two protective plates will block the rectangular opening.

[0018] These three features facilitate position adjustment of the protective mechanism. By pulling the lever upward, the protective plate moves up to expose the rectangular opening, allowing the rotating mechanism to rotate the support rod and change the position of the support ring. Releasing the lever causes the protective plate to return to its original position under the elastic force of the tension spring, thus blocking the rectangular opening again.

[0019] In summary, compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This chemical instrument corrosion resistance testing device, through the setting of components such as a rotating mechanism and a protective mechanism, after the test is completed, pulls the elastic mechanism upward, driving the protective mechanism to move upward, thus removing the restriction on the support rod and the obstruction of the rectangular opening between the lower and upper partitions. The rotating mechanism rotates the support rod 180°, moving the chemical instrument away from the closed door. The spraying mechanism sprays clean water onto the tested chemical instrument for cleaning. Afterward, the chemical instrument can be removed for observation, achieving the effect of removing chemical reagents from the chemical instrument. This solves the existing problems where chemical reagents remain on the chemical instrument after the test, making it inconvenient to remove the chemical instrument directly, and the chemical reagents also obscure the surface of the chemical instrument, making it difficult to observe.

[0021] 2. This chemical instrument corrosion resistance testing device, through the installation of two spraying mechanisms and other components, separates the two spaces during actual use via a protective mechanism. One space sprays chemical reagents for testing, while the other cleans the instruments that have completed the previous round of testing. Both sides can operate simultaneously. After each opening of the closed door, the cleaned instruments are removed, and the instruments that have not yet been tested are placed in and rotated again to improve work efficiency. The filter plate can also intercept residues to prevent contamination of water or chemical reagents, thus enabling recycling and saving resources. Attached Figure Description

[0035] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] Please see Figures 1-5 A chemical instrument corrosion resistance testing device includes a housing 1. Inside the housing 1, a lower partition 2 and an upper partition 3 are connected sequentially from bottom to top at the center. A rectangular opening is formed between the lower partition 2 and the upper partition 3. A support rod 4 is rotatably connected to the top of the lower partition 2 at the rectangular opening. Both ends of the support rod 4 are connected to support rings 5 ​​with a height smaller than the width of the rectangular opening. A filter plate 10 is installed inside the support rings 5. A spraying mechanism 6 is respectively provided on both sides of the lower partition 2 on the outside of the housing 1. A rotating mechanism 7 is provided at the center of the top of the support rod 4. A protective mechanism 8 is provided on the outside of the upper partition 3. A spring mechanism 9 is provided at the top of the protective mechanism 8. The upper half of one side wall of the housing 1 parallel to the upper partition 3 is open, and a closed door 11 is hinged inside the open.

[0038] The lower partition 2 divides the interior space of the housing 1 into two independent spaces. The space closer to the closed door 11 is used to store purified water, while the space farther from the closed door 11 is used to store chemical reagents. There are two support rings 5, and the filter plates 10 on them have multiple small holes to intercept solid impurities and perform filtration. Two spraying mechanisms 6 are installed on one side of the housing 1. One spraying mechanism 6 sprays chemical reagents onto the support ring 5 on the side farther from the closed door 11, and the other spraying mechanism 6 sprays purified water onto the support ring 5 closer to the closed door 11. The protective mechanism 8 can block the rectangular opening between the lower partition 2 and the upper partition 3, thereby completely separating the two independent spaces inside the housing 1 into two sealed working spaces. There is only one closed door 11, which can be rotated to close the housing 1. Locks and other components can also be installed on the closed door 11.

[0039] Additionally, it should be noted that drain pipes are installed at the bottom of the two independent spaces inside the casing 1, and on / off valves are installed on the drain pipes to discharge waste chemical reagents or sewage after a period of use.

[0040] In this embodiment, as Figure 2As shown, the spraying mechanism 6 includes a circulation pipe 601 whose bottom end is connected to the interior of the lower end of the housing 1. The circulation pipe 601 is fixedly connected to the outer wall of the housing 1. The upper end of the circulation pipe 601 is connected to a nozzle 602 facing the support ring 5 on the same side. A water pump 603 is fixedly installed on the outer wall of the housing 1 in the middle of the circulation pipe 601. The water pump 603 can draw the liquid in the lower part of the housing 1 into the interior of the circulation pipe 601 and then spray it out from the nozzle 602 at the upper part of the circulation pipe 601 so as to spray the chemical instruments on the filter plate 10 (including spraying chemical reagents and purified water).

[0041] Furthermore, such as Figures 2-3 As shown, the rotating mechanism 7 includes a connecting rod 701 whose bottom end is fixedly connected to the support rod 4 at the center. The connecting rod 701 is vertically rotatably engaged inside the upper partition 3 and its top end penetrates the top side wall of the housing 1. A rotating disk 702 is connected to the top of the connecting rod 701. By turning the rotating disk 702, the connecting rod 701 can be rotated, thereby driving the support rod 4 and the two support rings 5 ​​to rotate.

[0042] In this embodiment, as Figure 2 , Figure 4 As shown, the protective mechanism 8 includes two symmetrically sliding protective plates 801 that are clamped on both sides of the upper partition 3. During the up-and-down sliding process, the protective plates 801 can block the rectangular opening between the lower partition 2 and the upper partition 3. The lower end of the protective plate 801 has a notch in the middle for accommodating the support rod 4, which is used to clamp the support rod 4, thereby restricting the support rod 4 and preventing it from rotating.

[0043] Meanwhile, the height of the notch at the bottom of the protective plate 801 is greater than the width of the rectangular opening between the lower partition 2 and the upper partition 3. When the rectangular plate 803 is pressed tightly against the top surface of the housing 1 and the support rod 4 is stuck in the corresponding notch, the two protective plates 801 will block the rectangular opening.

[0044] Furthermore, the protective plate 801 is in the shape of an inverted L. Each protective plate 801 has two sliding rods 802 connected to its top. The sliding rods 802 are slidably inserted into the top side wall of the housing 1. A rectangular plate 803 is connected between the two sliding rods 802 on the same side of the two protective plates 801 outside the top of the housing 1. The sliding rods 802 on the two protective plates 801 are connected together through the rectangular plate 803, thereby connecting the two protective plates 801 together and making them move up and down synchronously.

[0045] In this embodiment, as Figure 5As shown, the elastic mechanism 9 includes two opposing fixed plates 901 in an inverted L-shape. The bottom end of the fixed plate 901 is fixedly connected to the rectangular plate 803 on the same side. A pull rod 903 is installed between the upper horizontal sections of the two fixed plates 901. The two fixed plates 901 are connected together by the pull rod 903. When the pull rod 903 is pulled upward, the two fixed plates 901 can be moved upward at the same time, thereby sequentially moving the rectangular plate 803, the sliding rod 802 and the protective plate 801 upward.

[0046] Furthermore, the elastic mechanism 9 also includes a tension spring 902. The bottom end of the tension spring 902 is connected to the top surface of the housing 1, and the top end of the tension spring 902 is connected to the bottom surface of the horizontal section of the fixing plate 901. The tension spring 902 can give the two fixing plates 901 a downward pulling force close to the housing 1, so that the fixing plates 901 automatically return to their downward position.

[0047] Finally, it should be noted that the water pump 603 and external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0048] Working principle:

[0049] In use, the following steps are taken: First, place the chemical instrument to be tested on the filter plate 10 inside the support ring 5 near the closed door 11. Pull the elastic mechanism 9 upward to move the protective mechanism 8 upward, thereby removing the restriction on the support rod 4 and exposing the rectangular opening between the lower partition 2 and the upper partition 3. Rotate the support rod 4 by rotating the rotating mechanism 7, rotating the support rod 4 180° to move the chemical instrument away from the closed door 11. Release the elastic mechanism 9, and under the action of the tension spring 902, move the protective mechanism 8 back to its original position. The protective mechanism 8 separates the housing 1 from the middle. Spray chemical reagents are sprayed onto the chemical instrument by the spraying mechanism 6 on the side away from the closed door 11 to detect the corrosion of the chemical instrument. After the test is completed, repeat the above operation of pulling the protective mechanism 8 and rotating the rotating mechanism 7 to rotate the tested chemical instrument back into the space near the closed door 11 in the same way. Then close the closed door 11 and spray clean water onto the tested chemical instrument by another spraying mechanism 6. After that, take out the chemical instrument for observation, thus achieving the effect of removing chemical reagents from the chemical instrument.

[0050] In actual use, the two independent spaces are separated by the protective mechanism 8. One space is sprayed with chemical reagents for testing, while the other space is used to clean the instruments that have been tested in the previous round. This can be done simultaneously. Each time the closed door 11 is opened, the chemical instruments that have been rinsed are taken out, and the instruments that have not yet been tested are put in and rotated to improve work efficiency. The filter plate 10 can also intercept residues to prevent contamination of water or chemical reagents, thus enabling recycling and saving resources.

[0051] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
