Description

Technical Field

[0001] The invention belongs to the technical field of hydrochloric acid corrosion test boxes, and in particular relates to a hydrochloric acid corrosion test box with a spray structure. Background Art

[0002] The hydrochloric acid corrosion test chamber is an important test equipment for studying the adaptability and reliability of various environments in the machinery, defense industry, light industry electronics, instrumentation and other industries. The corrosion chamber, as one of the "three-proof" (humid heat, salt spray, and mildew) test equipment for artificial climate environments, is mainly used to simulate specific environmental conditions to evaluate the performance of various materials or products in specific environments. In these environments, materials or products may undergo corrosion, aging and other processes, which will affect their service life and performance. By conducting hydrochloric acid corrosion tests in a corrosion chamber, the hydrochloric acid corrosion conditions that may be encountered in the actual use environment can be simulated, thereby evaluating the environmental adaptability and reliability of the tested object.

[0003] The salt spray test of the salt spray test chamber is mainly aimed at metal products, ranging from small accessories such as screws and nuts to entire metal objects, with varying volumes and sizes. There are also particular requirements for the placement of different items. The sample racks of the salt spray test chamber include: round bars, V-shaped sample racks and boxes. The V-shaped sample rack has a certain tilt angle, so small accessories can be placed directly inside the V-shaped sample rack for tilt tests. When encountering longer accessories, the V-shaped sample rack and the round bar are used together to make the items lean against the round bar for testing, and several separate round bars can lay the sheet samples flat on the round bar for testing. Since the tilt angle of the V-shaped sample rack is fixed, it is impossible to adjust the angle of the V-shaped sample rack according to the shape of the test sample, which makes it inconvenient to place the test items, so it needs to be improved.

DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0029] Example 1: Figure 1-9 As shown, a hydrochloric acid corrosion test box with a spray structure of the present invention comprises a base 1, a hydrochloric acid test box 11 and a control box 12 are installed on the upper end of the base 1, a spray structure connected to the control box 12 is installed inside the hydrochloric acid test box 11, and a placement mechanism is installed inside the hydrochloric acid test box 11, the placement mechanism comprises a fixing plate 13 symmetrically fixedly connected to the inside of the hydrochloric acid test box 11, two fixing plates 13 are provided with V-shaped grooves 14 on the side close to each other, and two fixing plates 13 are provided with connecting grooves 15 on the side away from each other, and the V-shaped grooves 14 and the connecting grooves 15 are connected through vertical grooves 16;

[0030] A rectangular block 20 is slidably connected inside the two symmetrical vertical slots 16, a round bar 21 is fixedly installed between the two rectangular blocks 20, an inclined plate 22 is rotatably installed on the round bar 21, and a connecting component matching the vertical slot 16 is installed on the two rectangular blocks 20. A step groove 23 is provided in the round bar 21 and the two rectangular blocks 20, a circular plate 24 is slidably connected inside the step groove 23, a spring 25 is installed between the circular plate 24 and the step groove 23, a pull rope 26 extending out of the rectangular block 20 is fixedly connected to the circular plate 24, and a limit rod 27 is installed in the two pull ropes 26. A plurality of limit arc bars 28 are symmetrically fixedly connected inside the hydrochloric acid test box 11. A combination of a round bar 21 and a limit rod 27 can be installed inside the plurality of symmetrical vertical slots 16.

[0031] The existing hydrochloric acid test box 11 can transport the brine stored in the control box 12, and then atomize and spray it through the spray structure to act on the objects placed inside the hydrochloric acid test box 11 to perform a hydrochloric acid test. At the same time, a sealed water tank is provided at the connection between the cover and the box body of the hydrochloric acid test box 11, so that it plays a water-tight state when the cover is closed. In addition, a drain valve connected to the interior of the hydrochloric acid test box 11 and the spray structure is installed in the hydrochloric acid test box 11, so that the brine inside the hydrochloric acid test box 11 and the spray structure is discharged after the test is completed.

[0032] When in use, the article to be tested for hydrochloric acid corrosion is placed in the hydrochloric acid test box 11, and its cover is closed. Then, the spray structure is started through the control box 12 to spray hydrochloric acid mist until the test is completed. When placing, the placement mechanism is adjusted according to the shape of the test article. In the initial state, the connecting component is not connected to the vertical groove 16, so that the placement mechanism can be removed at will, or the placement mechanism can be superimposed and placed in the V-shaped groove 14. When necessary, a round rod 21 is taken to align the rectangular block 20 with the vertical groove 16, and the rectangular block 20 is made to slide downward in the vertical groove 16, so that the two inclined plates 22 are moved away from each other under the action of gravity and abut against the side wall of the V-shaped groove 14. At this time, the round rod 21 and the rectangular block 20 continue to move downward, and the two inclined plates 22 are close to each other and the angle becomes smaller, until the rectangular block 20 slides to the bottom of the vertical groove 16 and the two inclined plates 2 2 is the smallest. At this time, the connecting assembly is connected to stabilize the rectangular block 20 in this state, so that items that need to be placed at an angle can be placed. When the angles of the two inclined plates 22 are large, items that cannot be placed in the V-shaped groove 14 with a larger diameter can be conveniently placed. At the same time, the pull rope 26 can be pulled to overcome the resilience of the spring 25 so that the pull rope 26 can move left and right inside the connecting groove 15, thereby facilitating the limiting rod 27 to arbitrarily select the position of the limiting arc strip 28 and make the limiting rod 27 abut against the inside of the two limiting arc strips 28, so that the inclined plate 22 and the limiting rod 27 are at different inclination angles and distances, which is convenient for long-handled items to be placed between the inclined plate 22 and the limiting rod 27, and the position and angle can be adjusted at will. At the same time, when not in use, the limiting rod 27 overlaps with the round rod 21 under the action of the spring 25 and the pull rope and is located between the two inclined plates 22 for easy storage.

[0033] When the inclined plates 22 are not needed to form a V shape, the two inclined plates 22 can be placed vertically downward by gravity, and the rectangular block 20 can be connected to the upper side of the vertical groove through a connecting component. In this way, the round rod 21 can be stably placed upward inside the hydrochloric acid test box 11, and a number of round rods 21 in this state can be used to place test items that need to be placed horizontally.

[0034] The present invention can adjust the angles of the two inclined plates 22 according to the state and characteristics of the test object to adapt to objects of different diameters. At the same time, it can also adjust the position of the limit rod 27 according to the length of a longer object, so that one end of the object is raised and abuts against the limit rod 7 to bear the weight. At the same time, several round rods 21 can be combined to place the test object horizontally.

[0035] Embodiment 2: Further improvement is made on the basis of Embodiment 1, the connecting assembly includes a round rod 30 rotatably connected to the rectangular block 20, a plurality of meshing teeth 31 are fixedly installed on the lower end of the round rod 30, a slide groove is provided inside the rectangular block 20, two half racks 32 meshing with the meshing teeth 31 are slidably connected to the slide groove, sockets matching the half racks 32 are provided on both sides of the vertical groove 16, and a rotating rod 33 is fixedly installed on the upper end of the round rod 30.

[0036] When sliding in the vertical groove 16, the two half racks 32 are located inside the rectangular block 20 to facilitate sliding. When the inclined plate 22 slides to the inclined angle, the rotating rod 33 is rotated to rotate the round rod 30 and the meshing teeth 31, and then the two half racks 32 extend outward and are inserted into the inside of the socket for locking.

[0037] The two inclined plates 22 are respectively fixedly installed with a coil spring box 34, and the two coil spring boxes 34 are symmetrically elastically connected to the round rod 21. The two inclined plates 22 are respectively fixedly installed with a swivel 35 rotatably connected to the round rod 21, and the two inclined plates 22 are respectively provided with a drainage groove 36 matching the swivel 35.

[0038] A coil spring is installed inside the coil spring box 34 to connect the inclined plate 22 and the round rod 21, so that the two inclined plates 22 are close to each other and remain perpendicular to the half rack 32 under the retraction force of the coil spring, so that the two inclined plates 22 abut the limit rod 27 in the middle for easy storage. In this way, when it is necessary to place items horizontally, the rotating rod 33 and the rectangular block 20 can be directly inserted into the vertical groove 16 to keep the round rod 21 facing upward.

[0039] The spray structure includes a water inlet pipe 40, a water storage box 41, a water blocking component and an atomizing component 42. The water inlet pipe 40 is connected to the control box 12 and the water storage box 41. The water blocking component is installed inside the water storage box 41. The atomizing component 42 is detachably installed on the upper end of the water storage box 41. The water blocking component includes a threaded barrel 43 threadedly connected to the water storage box 41, a mounting plate 44 is fixedly connected to the middle of the threaded barrel 43, a pressing pin 45 is slidably connected to the middle of the mounting plate 44, a rubber valve 46 matching the water inlet pipe 40 is installed on the threaded barrel 43 facing the water inlet pipe 40, a float arm 47 is rotatably installed on the mounting plate 44, and a push block 48 matching the pressing pin 45 is fixedly installed on the upper end of the float arm 47.

[0040] The control box 12 transports the salt water into the water storage box 41 through the water inlet pipe 40, and then atomizes and sprays it upward through the atomizing assembly 42. When the salt water accumulates in the water storage box 41 to a certain water level, the float arm 47 will rotate upward under the action of the float, and then the push block 48 will push the pressing pin 45 to press the rubber valve 46 close to the water inlet pipe 40, so that the rubber valve 46 will block and seal the water inlet pipe 40, so that the water from the water inlet pipe 40 cannot pass into the connecting tube connected to the water storage box 41 and the threaded tube 43, and then enter the water storage box 41. When the water level moves downward, the float arm 47 will rotate downward under the action of the float, and similarly, the blockage and seal of the rubber valve 46 and the water inlet pipe 40 can be released, so that the water in the water inlet pipe 40 can enter the water storage box 41 through the connecting tube.

[0041] A mounting ring 50 is rotatably installed on the threaded cylinder 43 near the water inlet pipe 40, and the mounting ring 50 is installed with a scraper strip 51 matching the water inlet pipe 40. A limit strip 52 is fixedly installed on the mounting ring 50, and a rotating cylinder 53 is rotatably installed on the water storage box 41. The rotating cylinder 53 is provided with a limit groove matching the limit strip 52, and the rotating cylinder 53 is installed with a rotating mechanism.

[0042] The rotating mechanism drives the rotating cylinder 53, the limiting strip 52, the mounting ring 50 and the scraping strip 51 to rotate, and then the scraping strip 51 rotates to scrape off the crystals of salt water precipitated at the blocked part of the water inlet pipe 40, and then discharges with the running water. When the threaded cylinder 43 is threadedly connected to the connecting cylinder, the limiting strip 52 is inserted into the limiting groove and then rotated to thread the connection.

[0043] The rotating mechanism includes a driving assembly and a toothed disc 54 transmission-connected thereto. The toothed disc 54 is rotationally connected to the hydrochloric acid test box 11. The hydrochloric acid test box 11 is rotationally connected to a gear column 55. A first gear ring 56 is fixedly installed on the circumference of the rotating cylinder 53. The gear column 55 is transmission-connected to the toothed disc 54 and the first gear ring 56.

[0044] The driving assembly drives the toothed disc 54 to rotate, and then drives the gear column 55 and the first gear ring 56 to rotate, so that the rotating cylinder 53 can be driven to rotate.

[0045] An eccentric column 57 is fixedly connected to the side of the toothed disc 54 away from the gear column 55, and the eccentric column 57 is sleeved with a limit frame 58. The hydrochloric acid test box 11 is provided with a matching groove slidably connected to the limit frame 58. The hydrochloric acid test box 11 is provided with a water storage tank 59 connected to the water inlet pipe 40. A sealing push rod 60 is fixedly installed on the upper end of the limit frame 58 and is sealingly and slidably connected to the water storage tank 59. The hydrochloric acid test box 11 is provided with a water inlet tank 61 connected to the water storage tank 59. The water inlet tank 61 is installed with a sealing plug 611. The diameter of the water inlet tank 61 is larger than the diameter of the water inlet pipe 40. Both the water inlet tank 61 and the water inlet pipe 40 are installed with a one-way water inlet valve 612.

[0046] The one-way water inlet valve 612 of the water inlet pipe 40 is installed at the connection between the water storage tank 59 and the water inlet pipe 40, so that the solution in the water storage tank 59 can only pass through the water inlet pipe 40 into the water storage box 41 and cannot flow to the other side of the water inlet pipe 40. When drainage is required, the sealing plug 611 is opened to allow the water that plays a water sealing role to enter the water inlet pipe 40 through the water inlet tank 61. Since the diameter of the water inlet tank 61 is larger than the diameter of the water inlet pipe 40, the water entering the water inlet tank 61 is discharged through the one-way water inlet valve 612. The valve 612 is temporarily retained inside the water storage tank. At this time, the driving assembly drives the gear disk 54 to rotate and then drives the eccentric column 57 to rotate, which will drive the limit frame 58 to reciprocate up and down, and then drive the sealing push rod 60 to move up and down. During the downward movement of the sealing push rod 60, the temporary storage solution inside the water storage tank 59 is squeezed into the water inlet pipe 40 to increase the water pressure between the one-way water inlet valve 612 and the water inlet pipe 40, thereby increasing the flushing force on the crystals and preventing the crystals from adhering to the blocked part of the water inlet pipe 40.

[0047] The driving assembly includes a driving ring 62, which is rotatably mounted at the connection point between the water storage tank 59 and the water inlet tank 61. The driving ring 62 is fixedly mounted with an inclined rotating blade 63 inside, the driving ring 62 is fixedly mounted with a first oblique tooth 64 outside, and the center of the toothed disc 54 is fixedly mounted with a second oblique tooth 65 meshing with the first oblique tooth 64. When water flows into the water inlet tank 61, the driving ring 62 and the first oblique tooth 64 are driven to rotate in the process of water passing through the oblique rotating blade 63, thereby driving the second oblique tooth 65 and the toothed disc 54 to rotate.

[0048] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
