Description

Technical Field

[0001] This utility model relates to the field of environmental testing equipment technology, and in particular to a salt spray corrosion test chamber. Background Technology

[0002] Salt spray corrosion test chambers are key equipment for simulating salt spray corrosion scenarios such as marine environments and industrial atmospheres. They are widely used in quality testing and R&D verification in fields such as aerospace, automobile manufacturing, and electronics.

[0003] Existing test chambers have some shortcomings when conducting salt spray corrosion tests on samples. Traditional spraying methods often lead to significant differences in salt spray concentration in different areas of the chamber, and insufficient sedimentation in corners, affecting the consistency and accuracy of test results. They also fail to provide sufficient salt spray treatment for the samples. To address these issues, an improved and upgraded salt spray corrosion test chamber is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a salt spray corrosion test chamber to solve the problems mentioned in the background art.

[0005] To solve the above problems, the following technical solution is provided: a salt spray corrosion test chamber, including a test platform, a control panel fixedly installed on the outer wall of the test platform, and a test chamber body fixedly installed on the upper side of one side of the test platform. A positioning structure is provided inside the test chamber body, and a spray structure is provided above the positioning structure. The spray structure includes a liquid storage tank fixedly installed on the upper part of the test chamber body. A connecting pipe is fixedly installed on the outer wall of the liquid storage tank, and a triangular pipe is fixedly installed at one end of the connecting pipe. A pump body is fixedly connected to the outer wall of the connecting pipe. A first connecting pipe is fixedly installed at one end of the triangular pipe, and one end of the first connecting pipe is fixedly installed on a rotating spray nozzle. Two second connecting pipes are fixedly installed at the other two joints of the triangular pipe, and a diverter pipe is fixedly installed at one end of each of the two second connecting pipes.

[0006] As a preferred embodiment of the above technical solution, the first connecting pipe passes through the interior of the test chamber and its extended end is fixedly installed on the housing of the rotating spray nozzle. The upper end of the rotating spray nozzle is connected to the drive motor, and a protective cover is fixedly fitted on the outer wall of the drive motor.

[0007] As a preferred embodiment of the above technical solution, the pump body is fixedly installed on the upper end of the test chamber, and the two second connecting pipes pass through both sides of the inside of the test chamber, with their extension ends fixedly connected to the inside of the diversion pipe. Multiple atomizing nozzles are fixedly installed on the outer wall of the diversion pipe.

[0008] As a preferred embodiment of the above technical solution, both ends of the two diversion pipes are fixedly installed with positioning blocks, and the positioning blocks are fixedly installed on the inner wall of the test chamber. Inside the test chamber, a collection plate is slidably connected below the nozzle.

[0009] As a preferred embodiment of the above technical solution, the positioning structure includes a positioning frame fixedly installed inside the test chamber. The upper end of the positioning frame is symmetrically provided with protrusions, and a placement plate is slidably connected to the outside of the protrusions. An electric motor is fixedly installed inside the placement plate.

[0010] As a preferred embodiment of the above technical solution, the output end of the motor is fixedly connected to a bidirectional lead screw, the outer wall of the bidirectional lead screw is symmetrically threaded with movable seats, and the upper end of each movable seat is fixedly installed with a clamping positioning plate. The outer wall of each clamping positioning plate is covered with an anti-slip pad, and the two movable seats are slidably connected to the placement plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model device is equipped with a spray structure. The salt spray liquid in the storage tank is drawn out through the connecting pipe by the driving pump body, and then transported to the first connecting pipe and the second connecting pipe through the triangular pipe. The liquid on the first connecting pipe falls down the outer shell onto the rotating spray nozzle, which is driven by the drive motor to rotate and spray the sample in all directions. At the same time, the salt spray liquid on the second connecting pipe is sprayed out from multiple atomizing nozzles through the diversion pipe to uniformly spray the side of the sample. This helps to improve the full salt spray treatment of the sample, avoid the problem of reduced accuracy of test results due to differences in salt spray concentration in different areas, and improve the reliability of test results.

[0013] 2. The device of this utility model is equipped with a positioning structure. The two moving seats on the bidirectional lead screw are driven by the drive motor to move relative to each other. The sample is stably fixed by the two clamping positioning plates. At the same time, the anti-slip pad is set to facilitate the relative stability of the sample clamping and avoid displacement. After the sample is fixed, the placement plate is slid into the test chamber along the direction of the protrusion, which is conducive to the stable clamping and positioning of the sample and facilitates relatively uniform spraying.

It should be understood that the embodiments of the present invention are not limited in scope.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 4 As shown in the figure, this embodiment provides a salt spray corrosion test chamber, including a test platform 1. A control panel is fixedly installed on the outer wall of the test platform 1, and a test chamber body 3 is fixedly installed on the upper side of one side of the test platform 1. A positioning structure 5 is provided inside the test chamber body 3, and a spray structure 4 is provided above the positioning structure 5. The spray structure 4 includes a liquid storage tank 41 fixedly installed on the upper end of the test chamber body 3. A connecting pipe is fixedly installed on the outer wall of the liquid storage tank 41, and a triangular pipe 43 is fixedly installed at one end of the connecting pipe. A pump body 42 is fixedly connected to the outer wall of the connecting pipe. A first connecting pipe 44 is fixedly installed at one end of the triangular pipe 43, and one end of the first connecting pipe 44 is fixedly installed on a rotating spray nozzle 46. The other two joints of the triangular pipe 43 are fixedly installed with second connecting pipes 47, and a diverter pipe 48 is fixedly installed at one end of each of the two second connecting pipes 47.

[0023] like Figures 2 to 3As shown, the first connecting pipe 44 passes through the inside of the test chamber 3 and its extended end is fixedly installed on the outer shell of the rotating spray nozzle 46. The upper end of the rotating spray nozzle 46 is connected to the drive motor 45, and a protective cover is fixedly fitted on the outer wall of the drive motor 45. The pump body 42 is fixedly installed on the upper end of the test chamber 3. The two second connecting pipes 47 pass through both sides inside the test chamber 3 and their extended ends are fixedly connected to the inside of the diversion pipe 48. Multiple atomizing nozzles 49 are fixedly installed on the outer wall of the diversion pipe 48. Positioning blocks are fixedly installed at both ends of the two diversion pipes 48 and are fixedly installed on the inner wall of the test chamber 3. A collection plate 2 is slidably connected inside the test chamber 3 below the nozzle.

[0024] The outer shell of the rotating spray nozzle 46 is fixedly installed on the inner wall of the test chamber 3. At the same time, one end of the drive motor 45 passes through the inside of the outer shell and is connected to the rotating spray nozzle 46, causing the rotating spray nozzle 46 to rotate to perform salt spray corrosion test on the sample. Multiple atomizing nozzles 49 are set to facilitate uniform spraying treatment on the side of the sample, thereby improving the fullness and uniformity of the spray.

[0025] like Figure 4 As shown, the positioning structure 5 includes a positioning frame 51 fixedly installed inside the test chamber 3. The upper end of the positioning frame 51 is symmetrically provided with protrusions 53 and a placement plate 52 is slidably connected to the outside of the protrusions 53. The placement plate 52 is fixedly installed inside the placement plate 52. The output end of the motor 54 is fixedly connected to a bidirectional lead screw 55. The outer wall of the bidirectional lead screw 55 is symmetrically threaded with movable seats 56 and a clamping positioning plate 57 is fixedly installed on the upper end of each movable seat 56. The outer wall of the clamping positioning plate 57 is covered with an anti-slip pad 58. Both movable seats 56 are slidably connected to the placement plate 52.

[0026] A transparent protective cover is installed on the outside of the test chamber 3 to facilitate the placement and removal of samples. When it is necessary to place a sample, simply move the placement plate 52 along the direction of the protrusion 53, and then move the placement plate 52 to the outside for easy placement by the operator. The anti-slip pad 58 is set to make the sample clamping and positioning relatively stable and prevent side slippage from affecting the spray treatment.

[0027] The working principle and operation process of this utility model are as follows: First, when a salt spray test is required, the sample to be tested is placed on the placement plate 52. Then, the external power supply is turned on, and the two moving seats 56 on the bidirectional lead screw 55 are moved relative to each other by the drive motor 54, thereby driving the two clamping and positioning plates 57 to move along the direction of the placement plate 52 to clamp and position samples of different sizes. After the sample is fixed, the sample on the placement plate 52 is moved along the direction of the protrusion 53 on the positioning frame 51 into the test chamber 3. Then, the outer transparent protective cover is closed, and the equipment is started. The pump body 42 is used to pump the liquid in the storage tank 41. The salt spray solution is drawn out through the connecting pipe and then transported to the first connecting pipe 44 and the two second connecting pipes 47 through the triangular pipe 43. The liquid in the first connecting pipe 44 flows to the rotating spray nozzle 46 inside the outer shell. Then, the rotating spray nozzle 46 is driven by the drive motor 45 to rotate and spray the sample from all directions. At the same time, the salt spray solution in the two second connecting pipes 47 flows into the diversion pipe 48 and is then sprayed out from multiple atomizing nozzles 49 to fully spray both sides of the sample, improving the adequacy of the salt spray corrosion detection. The sprayed salt spray drips onto the collection plate 2 below and is then processed uniformly.
