Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of salt spray testing machines, and in particular to a salt spray testing machine. Background Technology
[0002] The salt spray test chamber, also known as a salt spray test chamber, is used to test the reliability of samples by means of salt spray corrosion. Salt spray refers to a dispersion system in the atmosphere composed of tiny salt droplets. The salt spray test is an environmental test that mainly uses the artificial simulated salt spray environment conditions created by salt spray test equipment to assess the corrosion resistance of products or metal materials.
[0003] Existing salt spray testing machines typically use fixed nozzles when spraying items, making it difficult to spray the items evenly and thus easily leading to errors in the test results. Utility Model Content
[0004] Therefore, the technical problem to be solved by this utility model is to overcome the problem that it is difficult to spray the items evenly in the prior art, which easily leads to errors in the test results.
[0005] To solve the above-mentioned technical problems, this utility model provides a salt spray testing machine, including a control box; a test chamber is fixedly connected to one side of the control box, a water guide plate is fixedly connected to the top of the test chamber, an external water pipe is connected to the top of the water guide plate, multiple spray holes are connected to the bottom of the water guide plate, an air duct is provided on one side of the water guide plate, the air duct is fixedly connected to the test chamber, an external air pipe is connected to one side of the air duct, the external air pipe and external water pipe are fixedly connected to the test chamber, a motor is provided at one end of the air duct, the motor is fixedly connected to the test chamber, a rotating rod is fixedly connected to one end of the motor, a guide plate is fixedly connected to one end of the rotating rod, the rotating rod and guide plate are rotatably connected to the air duct, during operation, an item is placed in the middle of the test chamber, and the control box is operated. An external water pipe connects to salt water, which passes through a guide plate and is atomized by spray holes, dispersing into the center of the test chamber. An external air pipe connects to dry inert gas, and the airflow guides the salt mist to diffuse within the test chamber, reducing the accumulation of salt mist in one place and preventing uneven exposure of the items. After the motor starts, it drives the rotating rod to rotate, which in turn rotates the guide plate inside the air duct. The guide plate guides the direction of airflow, making the salt mist diffuse more evenly within the test chamber and distributed around the items. This ensures that the items are evenly exposed to the salt mist, reducing deviations in experimental results. By setting up air ducts, external air pipes, motors, rotating rods, and guide plates to guide the salt mist diffusion, the items are sprayed with salt mist more evenly, reducing the possibility of deviations in experimental results.
[0006] In one embodiment of this utility model, the bottom of the water guide plate is provided with multiple cylinders, which are fixedly connected to the test chamber. A bracket is fixedly connected to the top of the cylinder, and the surface of the bracket is provided with multiple mesh holes. During operation, the item is placed on the bracket, and the mesh holes reduce the area of the item being blocked, allowing the salt spray to act more comprehensively on the item. The cylinders can adjust the position of the bracket so that the item is exposed to different concentrations of salt spray, thereby making the experimental results more accurate. By setting up cylinders, brackets, and mesh holes, the item can be more fully exposed to the effect of salt spray, reducing the possibility of deviation in experimental results.
[0007] In one embodiment of this utility model, a vent pipe is provided on one side of the cylinder. The vent pipe is opened on the surface of the test chamber. A fan is connected to one side of the vent pipe. The fan is fixedly connected to the test chamber. One end of the fan is connected to a pipe, and one end of the pipe is connected to an alkaline liquid tank. An exhaust pipe is connected to the top of the alkaline liquid tank. During operation, after the test, a small amount of salt mist remains in the test chamber. The salt mist emitted to the outside can easily cause pollution to the external environment. When the fan is started, the vent pipe absorbs the salt mist into the pipe and transmits it to the alkaline liquid tank. After the reaction occurs in the alkaline liquid tank, the salt mist is emitted from the exhaust pipe. This reduces the possibility of salt mist being directly dispersed into the atmosphere and causing pollution to the external environment.
[0008] In one embodiment of this utility model, the bottom of the support is provided with a collection trough, which is located in the middle of the test chamber. When working, after the salt spray comes into contact with the object or the support, it gathers into water on the surface of the support and falls from the support into the collection trough. This allows for the concentrated collection of salt water, which is convenient for subsequent recycling.
[0009] In one embodiment of this utility model, a grid is provided on the top of the collection tank. The grid is fixedly connected to the test chamber. During operation, the grid is positioned above the collection tank to reduce the amount of items or debris falling into the collection tank and to perform preliminary filtration of the salt water collected in the collection tank, which facilitates subsequent processing.
[0010] In one embodiment of this utility model, a heating plate is provided at the bottom of the air duct. The heating plate is fixedly connected to the test chamber. During operation, the heating plate can easily heat the test chamber to provide a corresponding temperature environment for the experiment.
[0011] In one embodiment of this utility model, the cylinder is provided with an anti-corrosion elastic cloth. One end of the anti-corrosion elastic cloth is fixedly connected to the test chamber, and the other end of the anti-corrosion elastic cloth is fixedly connected to the bracket. During operation, the anti-corrosion elastic cloth is wrapped around the outside of the cylinder to reduce the corrosion of the cylinder by salt spray and reduce the impact on the service life of the cylinder.
[0012] In one embodiment of this utility model, the outer side of the mesh is provided on the guardrail, and the guardrail is fixedly connected to the bracket. During operation, the guardrail protects the items on the bracket and reduces the phenomenon of items accidentally falling to the outside of the bracket.
[0013] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:
[0014] The salt spray testing machine described in this utility model guides the salt spray to diffuse by setting up an air duct, an external air pipe, a motor, a rotating rod, and a guide plate, so that the salt spray is sprayed more evenly on the items and reduces the possibility of deviation in the test results.
[0015] The salt spray testing machine described in this utility model, by setting up a cylinder, a bracket, and a mesh, allows the items to come into more full contact with the salt spray, thereby reducing the probability of deviation in experimental results. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.
[0024] Reference Figures 1 to 3 As shown, this utility model discloses a salt spray testing machine, comprising a control box 1; a test chamber 11 is fixedly connected to one side of the control box 1; a water guide plate 12 is fixedly connected to the top of the test chamber 11; an external water pipe 13 is connected to the top of the water guide plate 12; multiple spray holes 14 are connected to the bottom of the water guide plate 12; an air duct 15 is provided on one side of the water guide plate 12; the air duct 15 is fixedly connected to the test chamber 11; an external air pipe 16 is connected to one side of the air duct 15; the external air pipe 16 and the external water pipe 13 are fixedly connected to the test chamber 11; a motor 17 is provided at one end of the air duct 15; the motor 17 is fixedly connected to the test chamber 11; a rotating rod 18 is fixedly connected to one end of the motor 17; a guide plate 19 is fixedly connected to one end of the rotating rod 18; the rotating rod 18, the guide plate 19, and the air duct 15 are rotatably connected. During operation, an item is placed into the test chamber 11. The test chamber 11 is equipped with a control box 1 and an external water pipe 13 connected to salt water. The salt water passes through a guide plate 12 and is atomized by spray holes 14, spreading to the center of the test chamber 11. An external air pipe 16 is connected to dry inert gas. The airflow guides the salt mist to diffuse within the test chamber 11, reducing the accumulation of salt mist in one place and preventing uneven effects on the items. After the motor 17 starts, it drives the rotating rod 18 to rotate, which in turn causes the guide plate 19 to rotate within the air duct 15. The guide plate 19 guides the direction of airflow, making the salt mist diffuse more evenly within the test chamber 11 and distributed around the items. This ensures that the items are evenly affected by the salt mist and reduces the deviation of experimental results. By setting up the air duct 15, external air pipe 16, motor 17, rotating rod 18, and guide plate 19, the salt mist is guided to diffuse, making the items more evenly sprayed with salt mist and reducing the possibility of deviation in experimental results.
[0025] Reference Figures 1 to 5 As shown, the bottom of the water guide plate 12 is equipped with multiple cylinders 2, which are fixedly connected to the test chamber 11. A bracket 21 is fixedly connected to the top of the cylinder 2, and multiple mesh holes 22 are opened on the surface of the bracket 21. During operation, the items are placed on the bracket 21, and the mesh holes 22 reduce the area of the items being blocked, so that the salt spray can act on the items more comprehensively. The cylinders 2 can adjust the position of the bracket 21 so that the items are exposed to different concentrations of salt spray, thereby making the experimental results more accurate. By setting up the cylinders 2, brackets 21, and mesh holes 22, the items can be more fully exposed to the effect of salt spray, reducing the deviation of experimental results.
[0026] Reference Figures 1 to 2As shown, a vent pipe 3 is provided on one side of the cylinder 2. The vent pipe 3 is located on the surface of the test chamber 11. A fan 31 is connected to one side of the vent pipe 3. The fan 31 is fixedly connected to the test chamber 11. One end of the fan 31 is connected to a pipe 32. One end of the pipe 32 is connected to an alkaline liquid tank 33. An exhaust pipe 34 is connected to the top of the alkaline liquid tank 33. During operation, after the test, a small amount of salt mist remains in the test chamber 11. The salt mist emitted to the outside can easily cause pollution to the external environment. When the fan 31 is started, the vent pipe 3 absorbs the salt mist into the pipe 32, and then transmits it to the alkaline liquid tank 33 through the pipe 32. After the reaction occurs in the alkaline liquid tank 33, it is emitted from the exhaust pipe 34. This reduces the possibility of salt mist being directly dispersed into the atmosphere and causing pollution to the external environment.
[0027] Reference Figures 1 to 2 As shown, the bottom of the support 21 is provided with a collection tank 4, which is located in the middle of the test chamber 11. When working, after the salt spray comes into contact with the object or the support 21, it gathers into water on the surface of the support 21. After gathering, it falls from the support 21 into the collection tank 4, which can collect the salt water in a concentrated manner, making it convenient for subsequent recycling.
[0028] Reference Figures 1 to 2 As shown, the top of the collection tank 4 is provided with a grid mesh 5, which is fixedly connected to the test chamber 11. During operation, the grid mesh 5 blocks the area above the collection tank 4, reducing the amount of items or debris falling into the collection tank 4, and performing preliminary filtration on the salt water collected in the collection tank 4, which is convenient for subsequent processing.
[0029] Reference Figures 1 to 2 As shown, the bottom of the air duct 15 is provided with a heating plate 6, which is fixedly connected to the test chamber 11. During operation, the heating plate 6 can heat the test chamber 11 to provide a corresponding temperature environment for the experiment.
[0030] Reference Figures 1 to 4 As shown, the cylinder 2 is provided with a corrosion-resistant elastic cloth 7 on the outside. One end of the corrosion-resistant elastic cloth 7 is fixedly connected to the test chamber 11, and the other end of the corrosion-resistant elastic cloth 7 is fixedly connected to the bracket 21. During operation, the corrosion-resistant elastic cloth 7 wraps around the outside of the cylinder 2 to reduce the corrosion of the cylinder 2 by salt spray and reduce the impact on the service life of the cylinder 2.
[0031] Reference Figures 1 to 5 As shown, the outer side of the mesh 22 is provided on the guardrail 8, and the guardrail 8 is fixedly connected to the bracket 21. During operation, the guardrail 8 protects the items on the bracket 21 and reduces the phenomenon of items accidentally falling to the outside of the bracket 21.
[0032] Working principle: The item is placed in the middle of the test chamber 11. The control box 1 is operated, and the external water pipe 13 is connected to the salt water. The salt water passes through the water guide plate 12 and is atomized after being sprayed through the spray hole 14, spreading to the middle of the test chamber 11. The external air pipe 16 is connected to dry inert gas. The airflow guides the salt mist to diffuse within the test chamber 11, reducing the accumulation of salt mist in one place and preventing uneven distribution of the salt mist on the item. After the motor 17 is started, it drives the rotating rod 18 to rotate, which in turn causes the guide plate 19 to rotate within the air duct 15. The guide plate 19 can guide the direction of airflow, making the salt mist diffuse more evenly within the test chamber 11. Distributed around the items, this ensures uniform salt spray exposure, reducing experimental result deviations. The salt spray is guided by duct 15, external air pipe 16, motor 17, rotating rod 18, and guide plate 19, resulting in more even salt spray coverage and minimizing deviations in experimental results. The items are placed on support 21, with mesh 22 reducing obstruction and allowing the salt spray to reach the items more comprehensively. Cylinder 2 can adjust the position of support 21, varying the salt spray concentration on the items to improve experimental accuracy. The setup of cylinder 2 and support... 21. Mesh 22 allows for more thorough contact between the items and the salt spray, reducing deviations in experimental results. After the experiment, a small amount of salt spray remains inside the test chamber 11, potentially causing environmental pollution. The fan 31 starts, and the ventilation pipe 3 draws the salt spray into the pipe 32, which then transports it to the alkaline liquid tank 33. After reacting in the alkaline liquid tank 33, the salt spray is released from the exhaust pipe 34, thus reducing the direct release of salt spray into the atmosphere and its potential environmental pollution. When the salt spray comes into contact with the items or the support 21, it collects as water on the surface of the support 21, which then flows out from the support 21. The salt water falls into the collection tank 4, which allows for centralized collection of salt water for subsequent recycling. The grid 5 is placed above the collection tank 4 to reduce the amount of items or debris falling into the collection tank 4. The salt water collected in the collection tank 4 is initially filtered for subsequent processing. The heating plate 6 is used to heat the test chamber 11 and provide the appropriate temperature environment for the experiment. The anti-corrosion elastic cloth 7 is wrapped around the outside of the cylinder 2 to reduce the corrosion of the cylinder 2 by salt spray, which would affect the service life of the cylinder 2. The guardrail 8 protects the items on the support 21 and reduces the occurrence of items accidentally falling outside the support 21.
[0033] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
