Description

Technical Field

[0001] The invention belongs to the technical field of metal material corrosion resistance detection, and specifically relates to an intelligent salt spray chamber based on full-automatic salt solution replenishment and monitoring protection functions. Background Art

[0002] Salt spray chamber, also known as salt spray test machine or salt water spray test machine, is mainly used to simulate salt spray corrosion conditions in marine or coastal environmental conditions to evaluate the corrosion resistance of products or metal materials.

[0003] Salt spray chambers usually use imported PVC reinforced hard plastic plates as the chamber material, which has a smooth surface, is resistant to aging and corrosion, easy to clean, and leak-free. The chamber cover is made of fully transparent impact-resistant plates, which is convenient for observing the test conditions of the test samples during the test. As an important environmental testing equipment, salt spray chambers have broad application prospects in the fields of material science, electronic products, and automotive parts.

[0004] When the salt spray chamber is used to conduct corrosion resistance tests on metal materials, the condition of the internal products is observed through the cover of the chamber. However, a large amount of water mist is generated inside when the spray is produced. The water mist gathers upward on the cover of the chamber, blocking the human field of vision, making it impossible to clearly see the test condition of the internal products. In addition, the sealing of the connection port of the chamber cover is poor after it is closed, and the salt spray inside will leak out from the gap. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide an intelligent salt spray box based on the full-automatic supply and monitoring protection function of salt solution, comprising a salt spray box body, the upper surface of the salt spray box body is rotatably connected with a box cover, the side surface of the salt spray box body is provided with a fixing device, the side surface of the salt spray box body is fixedly connected with a first motor, the output end of the first motor is fixedly connected with a reciprocating threaded rod, the side surface of the reciprocating threaded rod is threadedly connected with a sleeve, the side surface of the sleeve is fixedly connected with a clamping plate, the upper surface of the clamping plate is fixedly connected with a column, the upper surface of the column is fixedly connected with a scraper, the upper surface of the salt spray box body is provided with a groove, and the top inner wall of the box cover is fixedly connected with an L-shaped sealing plate.

[0006] The technical solution adopted to solve the above technical problems is: when the salt mist generated by the device is running, it will adhere to the box cover. At this time, the first motor can be started to rotate the reciprocating threaded rod, so that the sleeve drives the scraper to produce reciprocating displacement. During the displacement, the scraper scrapes off the salt mist attached to the box cover, providing a visual range for the user to observe the corrosion of the internal metal material through the box cover, and the clamping plate of the sleeve clamps the L-shaped sealing plate when the sleeve is displaced, thereby improving the firmness of the box cover after closing, and the fixing device fixes the position of the box cover after closing.

[0007] Furthermore, the side surface of the reciprocating threaded rod is rotatably connected to the salt spray chamber body, the side surface of the sleeve is fixedly connected to a limit plate, and the side surface of the limit plate is in contact with the salt spray chamber body.

[0008] Through the above technical solution, the side surface of the limiting plate is in contact with the salt spray chamber, and when the reciprocating threaded rod rotates, the rotation of the sleeve is limited so that the sleeve is displaced along the direction of the reciprocating threaded rod.

[0009] Furthermore, the fixing device includes an electromagnet and a spring, a handle is fixedly connected to the side surface of the box cover, an iron sheet is fixedly connected to the lower surface of the handle, and the lower surface of the iron sheet is magnetically connected to the electromagnet.

[0010] Through the above technical scheme, the box cover can be opened by the handle, and the iron sheet can be adsorbed to close the box cover when the electromagnet is energized. When the electromagnet is de-energized, the iron sheet loses its adsorption force, and the iron sheet moves away from the electromagnet during the reset of the spring, thereby lifting the box cover.

[0011] Furthermore, the lower surface of the clamping plate and the upper surface of the L-shaped sealing plate are located on the same horizontal plane, and the upper surface of the scraper is in contact with the box cover.

[0012] Through the above technical solution, the upper surface of the scraper is in contact with the box cover, so that the scraper can scrape off the salt mist attached to the box cover and provide a field of view for the experimenter.

[0013] Furthermore, a vertical rod is fixedly connected to the side surface of the sleeve, a bottom plate scraper is fixedly connected to the lower end of the vertical rod, and the lower surface of the bottom plate scraper is in contact with the salt spray chamber body.

[0014] Through the above technical solution, the bottom plate scraper will move with the sleeve, and the salt deposited on the bottom inner wall of the salt spray box body will be scraped off during the displacement, so as to facilitate the cleaning of the bottom of the salt spray box body when the brine inside the salt spray box body is released later.

[0015] Furthermore, a storage plate is provided on the side inner wall of the salt spray box body, a spray device is provided inside the salt spray box body, a control panel is provided on the front surface of the salt spray box body, a drain port is provided on the rear surface of the salt spray box body, and a connecting pipe is provided on the rear surface of the salt spray box body.

[0016] Furthermore, a pure water supply pipe is provided on the rear surface of the salt spray box body, and a brine tank is provided on the upper surface of the salt spray box body.

[0017] Furthermore, an electric telescopic rod is fixedly connected to the upper surface of the salt spray chamber body, an output end of the electric telescopic rod is fixedly connected to a mounting frame, and a cover is fixedly connected to the lower surface of the mounting frame.

[0018] Furthermore, a second motor is fixedly connected to the upper surface of the cover, a stirring rod is fixedly connected to the output end of the second motor, and a feeding port is arranged on the upper surface of the cover.

[0019] Through the above technical solution, after the second motor is powered on and started, the stirring rod will rotate, thereby stirring the solution inside the brine tank to avoid uneven mixing of the solution.

[0020] The beneficial effects of the present invention are as follows:

[0021] (1) The scraper can be reciprocated by the reciprocating threaded rod, sleeve, limit plate, clamping plate, column and scraper, so that the scraper can move back and forth, and the salt spray attached to the closed box cover can be scraped off during the displacement, so that the user can observe the metal corrosion inside the salt spray box body from the box cover, avoiding the situation where the salt spray is too severe to be observed;

[0022] (2) When the sleeve moves, the clamping plate can limit the L-shaped sealing plate, thereby limiting the box cover to prevent the box cover from opening during use and causing salt mist to leak out. When the electromagnet is energized, it can absorb the iron sheet to increase the tightness of the box cover after it is closed;

[0023] (3) The groove cooperates with the box cover, and the lower end of the box cover is located in the groove for injecting water after it is closed, thereby increasing the sealing performance of the box cover after it is closed and reducing the occurrence of salt spray leakage.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] like Figure 1-Figure 6 As shown, the intelligent salt spray box based on the full-automatic supply and monitoring protection function of the salt solution of the present embodiment comprises a salt spray box body 1, the upper surface of the salt spray box body 1 is rotatably connected with a box cover 2, the box cover 2 is closed when the device is running to prevent the internal salt spray from diffusing into the room and causing harm to the experimenters and other equipment in the room, the side surface of the salt spray box body 1 is provided with a fixing device, the fixing device fixes the position of the box cover 2 after closing, so that the sealing of the device is improved, the fixing device comprises an electromagnet 5 and a spring 6, the side surface of the box cover 2 is fixedly connected with a handle 3, the lower surface of the handle 3 is fixedly connected with an iron sheet 4, the lower surface of the iron sheet 4 is magnetically connected to the electromagnet 5, after the box cover 2 is closed, the electromagnet 5 is energized to adsorb the iron sheet 4, at this time, the spring 6 compresses the box cover 2 to close, when the electromagnet 5 is powered off, the adsorption of the iron sheet 4 disappears, at this time, the spring 6 resets to lift the box cover 2, which can prevent the water in the groove 15 from affecting the box cover 2 and help the experimenter open the box cover 2.

[0033] The side surface of the salt spray box body 1 is fixedly connected with a first motor 7, and the electrical connection between the first motor 7 and the external power supply is a prior art. The output end of the first motor 7 is fixedly connected with a reciprocating threaded rod 8, and the side surface of the reciprocating threaded rod 8 is threadedly connected with a sleeve 9. The side surface of the reciprocating threaded rod 8 is rotatably connected to the salt spray box body 1, and the side surface of the sleeve 9 is fixedly connected with a limiting plate 10. The side surface of the limiting plate 10 contacts the salt spray box body 1. When the first motor 7 rotates the reciprocating threaded rod 8, the sleeve 9 is displaced under the action of the limiting plate 10, and the scraper 13 installed above will be displaced synchronously during the displacement. The side surface of the sleeve 9 is fixedly connected with a clamping plate 11, and the clamping plate 11 When following the displacement of the sleeve 9, the card plate 11 is located above the L-shaped sealing plate 14 to prevent the box cover 2 from opening suddenly due to the disconnection of the electromagnet 5 or the box cover 2 from opening while being scraped by the scraper 13, which may cause the leakage of salt mist. The upper surface of the card plate 11 is fixedly connected to the column 12, and the upper surface of the column 12 is fixedly connected to the scraper 13. The scraper 13 scrapes off the salt mist attached to the box cover 2 during the displacement, so that the experimenter can view the internal situation from the scraped box cover 2. The material of the box cover 2 is a transparent impact-resistant plate. The lower surface of the card plate 11 and the upper surface of the L-shaped sealing plate 14 are located on the same horizontal plane, and the upper surface of the scraper 13 is in contact with the box cover 2.

[0034] The upper surface of the salt spray box body 1 is provided with a groove 15. The lower end of the box cover 2 is located in the groove 15 after closing. At this time, pure water can be added into the groove 15 to improve the sealing performance of the device. The top inner wall of the box cover 2 is fixedly connected with an L-shaped sealing plate 14. There is a gap between the side surface of the L-shaped sealing plate 14 and the salt spray box body 1 to prevent the box cover 2 from being unable to open. The side surface of the sleeve 9 is fixedly connected with a vertical rod 16. The lower end of the vertical rod 16 is fixedly connected with a bottom plate scraper 17. The bottom plate scraper 17 can scrape the bottom inner wall of the salt spray box body 1 during displacement. The precipitated salt is suspended, and when the salt spray box body 1 is cleaned later, the situation that the salt sinks to the bottom and is difficult to clean can be avoided. The lower surface of the bottom plate scraper 17 is in contact with the salt spray box body 1. The side inner wall of the salt spray box body 1 is provided with a storage plate 18, which is movably placed inside the salt spray box body 1 for placing metal plates and objects to be tested. A spray device 19 is provided inside the salt spray box body 1, and a control panel 30 is provided on the front surface of the salt spray box body 1. The indicators of the device can be adjusted through the control panel 30.

[0035] The rear surface of the salt spray box body 1 is provided with a drain port 20, a valve is provided inside the drain port 20, a connecting pipe 21 is provided on the rear surface of the salt spray box body 1, a pure water supply pipe 22 is provided on the rear surface of the salt spray box body 1, a valve is provided inside the pure water supply pipe 22, a brine tank 23 is provided on the upper surface of the salt spray box body 1, and an electric telescopic rod 24 is fixedly connected to the upper surface of the salt spray box body 1. The electric telescopic rod 24 can raise the height of the cover 26 by telescoping, so as to facilitate cleaning of the inside of the brine tank 23. A mounting frame 25 is fixedly connected to the output end, a cover 26 is fixedly connected to the lower surface of the mounting frame 25, a second motor 27 is fixedly connected to the upper surface of the cover 26, a stirring rod 28 is fixedly connected to the output end of the second motor 27, the stirring rod 28 rotates under the action of the second motor 27 to stir the solution in the brine tank 23 to avoid uneven stirring, a feeding port 29 is provided on the upper surface of the cover 26, brine can be added to the brine tank 23 through the feeding port 29, and a hydrometer for detecting the brine concentration can be placed through the feeding port 29 to measure the brine concentration.

[0036] The working principle of this embodiment is as follows: when using this device, pure water is added through the pure water adding pipe 22, and the well-proportioned brine is added into the brine tank 23, and the second motor 27 is started to make the stirring rod 28 stir the brine, and the metal material to be detected is placed on the storage plate 18, and the box cover 2 is closed. At this time, the lower end of the box cover 2 is located in the groove 15, and pure water is added into the groove 15. The power is turned on to make the electromagnet 5 energized to adsorb the iron sheet 4. At this time, when the device is started, the spray device 19 sprays salt mist, and the generated mist makes it impossible to see the inside of the box cover 2 clearly. A motor 7 rotates the reciprocating threaded rod 8, thereby causing the sleeve 9 to move back and forth. During the displacement, the scraper 13 scrapes the water mist on the box cover 2, and people can see the internal situation through the box cover 2. When the sleeve 9 is displaced, the clamping plate 11 will always be located on the upper surface of the L-shaped sealing plate 14, which limits the closing of the box cover 2, making the closure of the box cover 2 more secure to avoid self-opening and causing salt mist diffusion to cause harm to the human body. In addition, when the sleeve 9 is displaced, it can drive the bottom plate scraper 17 to scrape the bottom inner wall of the salt spray box body 1 to avoid the inconvenience of salt settling and accumulation at the bottom and later cleaning.

[0037] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
