Description

Technical Field

[0001] This utility model relates to the field of salt spray testing technology, and in particular to a salt spray testing machine. Background Technology

[0002] A salt spray test chamber is a device used to simulate a salt spray environment to test the corrosion resistance of metal materials and their protective layers. By simulating a salt spray environment to accelerate the corrosion process of materials, it can quickly evaluate the corrosion resistance of materials and their protective layers, providing important basis for product quality control and research and development.

[0003] A search revealed a Chinese patent publication number: CN220136946U, entitled "Salt Spray Tester," which includes a salt spray test chamber with a cover plate on top and a control box on one side of the chamber surface. Expansion components capable of sealing the cover plate are arranged around the opening of the salt spray test chamber. This utility model belongs to the technical field of salt spray testers. Its purpose is to solve the problem of insufficient sealing caused by long-term friction between the side walls and cover plate of the salt spray tester, leading to gaps. The technical effect achieved is that by inflating the air bag, the air bag expands, causing the side walls, air bag, and exhaust pipe of the salt spray test chamber to expand within the T-shaped groove, achieving a seal and preventing insufficient sealing due to long-term friction between the side walls and cover plate. This ensures the normal use of the salt spray tester. However, the large contact area between the product and the surface after placement hinders the uniform coverage of the salt spray on the product surface during the salt spray test. This results in some areas of the product not being fully exposed to salt spray corrosion, making the test results unable to accurately reflect the product's true corrosion resistance and reducing the accuracy and reference value of the test. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a salt spray test chamber, which aims to improve the problem that the contact area between the product and the placement surface is too large, resulting in some areas of the product not being able to fully accept salt spray corrosion, and thus the test results cannot accurately reflect the true corrosion resistance performance of the product.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a salt spray test chamber, comprising a test cabinet, a spray chamber on the left side of the interior of the test cabinet, a fixed rod fixedly connected to the left side of the spray chamber, an electric telescopic rod fixedly connected to the right side of the interior of the test cabinet, clamps fixedly connected to the right end of the fixed rod and the output end of the electric telescopic rod, multiple anti-slip strips fixedly connected at equal intervals inside the two clamps, a salt water tank fixedly connected to the bottom right end of the interior of the test cabinet, a feeding trough connected to the rear right side of the salt water tank, a water injection pipe connected to the front right side of the salt water tank, a leakage hole in the middle of the interior of the test cabinet, a recovery chamber in the bottom left end of the interior of the test cabinet, the spray chamber, the leakage hole and the recovery chamber being connected, a sealing assembly provided at the front left end of the test cabinet, and an atomizing mechanism provided inside the salt water tank.

[0006] The above technical solution achieves the following: the sample is fixed by a clamping plate driven by an electric telescopic rod; the atomizing mechanism prepares salt water and converts it into salt spray, which is then sprayed onto the sample through a spray chamber; and the salt water is recovered through a leak and a recovery chamber. This achieves the effects of accurately simulating the salt spray environment, efficiently recovering salt water, and accurately evaluating the corrosion resistance of the sample. It avoids the problem of excessive contact area and too many contact points between the product and the mesh surface, which is not conducive to the corrosion of the salt spray and affects the test results. At the same time, it solves the problem of salt spray waste.

The diverter pipe is fixedly installed at the top of the spray chamber. Multiple atomizing nozzles are equidistantly connected to the bottom of the diverter pipe.

[0009] The above technical solution involves using a rotating motor to drive the stirring blades to agitate the brine, a water pump in conjunction with a connecting pipe and a fine filter to extract and filter the brine, and finally a distributor pipe and atomizing nozzle to convert the brine into salt mist. This ensures uniform brine concentration, removes impurities, and produces a uniform and fine salt mist, providing reliable conditions for simulating natural salt mist and improving experimental accuracy.

[0010] As a further description of the above technical solution:

[0011] The sealing assembly includes a sealing plate, which is rotatably connected to the middle of the front side of the test chamber. A reinforcing strip is fixedly connected to the top of the sealing plate. A fixing pin passes through the left and right ends of the front side of the reinforcing strip. The ends of the two fixing pins are respectively threaded to the left end and the middle of the front side of the test chamber.

[0012] Through the above technical solution: the reinforcing strip fixedly connected to the top of the sealing plate can enhance the overall strength of the sealing plate. The ends of the two fixing pins are aligned with the threaded holes reserved on the front left side and the front middle side of the test cabinet, respectively, and then threaded connection is made. By rotating the fixing pins, they are tightly screwed into the test cabinet to ensure that the test cabinet is in a sealed state and effectively prevent salt spray from leaking into the external environment.

[0013] As a further description of the above technical solution:

[0014] An electric control button is fixedly connected to the upper middle part of the left side of the front side of the test cabinet, and the electric control button is electrically connected to the electric telescopic rod.

[0015] The above technical solution allows for the rapid start or stop of the electric telescopic rod by pressing the electronic control button. When it is necessary to fix the sample, pressing the electronic control button causes the electric telescopic rod to move the clamping plate to clamp the sample. After the test, pressing the electronic control button again resets the electric telescopic rod, simplifying the sample fixing and removal process.

[0016] As a further description of the above technical solution:

[0017] An electrically controlled discharge valve is connected to the bottom left side of the test cabinet, and the input end of the electrically controlled discharge valve is connected to the recovery chamber.

[0018] The above technical solution allows for the following: after the salt spray test is completed, the electronically controlled discharge valve can be opened via the control console, and the brine collected in the recovery chamber can be discharged through the electronically controlled discharge valve, facilitating centralized treatment of the recovered brine.

Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model provides a salt spray test chamber, including a test cabinet 1. A spray chamber 3 is provided on the left side of the interior of the test cabinet 1. A fixed rod 4 is fixedly connected to the left side of the spray chamber 3. An electric telescopic rod 5 is fixedly connected to the right side of the interior of the test cabinet 1. A clamping plate 6 is fixedly connected to the right end of the fixed rod 4 and the output end of the electric telescopic rod 5. Multiple anti-slip strips 7 are fixedly connected at equal intervals inside the two clamping plates 6. A salt water tank 8 is fixedly connected to the bottom right end of the interior of the test cabinet 1. A feeding trough 9 is connected to the rear right end of the salt water tank 8. A water injection pipe 10 is connected to the front right end of the salt water tank 8. A leakage hole 11 is provided in the middle of the interior of the test cabinet 1. A recovery chamber 12 is provided at the bottom left end of the interior of the test cabinet 1. The spray chamber 3, the leakage hole 11 and the recovery chamber 12 are connected. A sealing component is provided at the front left end of the test cabinet 1. An atomizing mechanism 2 is provided inside the salt water tank 8.

[0040] Specifically, before conducting the salt spray test, the sample to be tested is placed inside the test cabinet 1. Inside the test cabinet 1, the spray chamber 3 on the left and the electric telescopic rod 5 on the right work together to fix the sample. The fixing rod 4 is fixed to the left side of the spray chamber 3, and its right end is connected to a clamping plate 6 at the output end of the electric telescopic rod 5. When the electric telescopic rod 5 is activated, its output end extends, causing the clamping plate 6 to move and cooperate with the left clamping plate 6 to clamp and fix the sample between the two clamping plates 6. Multiple anti-slip strips 7, equidistantly connected inside the clamping plates 6, increase the friction between the clamping plates 6 and the sample, ensuring that the sample does not shift during the test and guaranteeing the accuracy of the test. The salt water tank 8 is fixed to the bottom right side inside the test cabinet 1. An appropriate amount of salt is added to the salt water tank 8 through the feeding trough 9, and a certain amount of water is injected through the water injection pipe 10. The atomizing mechanism 2 inside the salt water tank 8 can evenly mix the salt water mixture to prepare a salt water solution with the required concentration for the test. The atomized salt spray is then sprayed into the spray chamber 3, ready to spray the sample. The salt spray in chamber 3 evenly diffuses to the sample area, simulating the salt spray corrosion in the natural environment. During the salt spraying process, excess salt spray and salt water flowing down from the sample surface drip down through the drain hole 11 in the middle of the inner side of the test cabinet 1. Since the spray chamber 3, the drain hole 11, and the recovery chamber 12 are connected, the dripping salt water and salt spray eventually flow into the recovery chamber 12, realizing the recovery of salt water, avoiding waste and environmental pollution. The sealing component set at the front left end of the test cabinet 1 can ensure that the test cabinet 1 is in a sealed state during the test, preventing salt spray from leaking into the external environment, ensuring the stability of the test environment and the safety of the operators. The test time and salt water concentration parameters can be controlled according to the test standards. By observing the corrosion of the sample in the salt spray environment, the corrosion resistance of the sample can be evaluated. This avoids the problem of salt spray waste caused by the traditional method of using a mesh placement surface, which results in an excessively large contact area and too many contact points between the product and the placement surface, making it unable to accept the corrosion of salt spray well.

[0041] Reference Figure 3 and Figure 5 The atomizing mechanism 2 includes a rotating motor 201, which is fixedly connected to the bottom of the test cabinet 1. The output end of the rotating motor 201 is fixedly connected to a stirring blade 202, which is rotatably connected to the inside right side of the brine tank 8. A water pump 203 is fixedly connected to the inside right side of the test cabinet 1. The input end of the water pump 203 is connected to a connecting pipe 204, the bottom of which penetrates the inside of the brine tank 8. The input end of the connecting pipe 204 is connected to a fine filter 205. The output end of the water pump 203 is connected to a diversion pipe 206, which is fixedly installed on the top of the spray chamber 3. Multiple atomizing nozzles 207 are equidistantly connected to the bottom of the diversion pipe 206.

[0042] Specifically, during the preparation stage of the salt spray test chamber, a rotating motor 201 is fixedly connected to the bottom of the test chamber 1, and its output end is fixedly connected to a stirring blade 202. The stirring blade 202 is rotatably connected to the right side inside the brine tank 8. When salt and water are added to the brine tank 8, the rotating motor 201 is started, and its output end drives the stirring blade 202 to rotate inside the brine tank 8. The rotation of the stirring blade 202 ensures that the salt and water in the brine tank 8 are fully mixed, ensuring the preparation of brine with uniform concentration, providing a stable raw material for subsequent salt spray generation. The input end of a water pump 203, fixedly connected to the right side inside the test chamber 1, is connected to the brine tank 8 through a connecting pipe 204. The bottom of the connecting pipe 204 penetrates inside the brine tank 8, and its input end is connected to a fine filter 205. After the water pump 203 is started, it generates suction, drawing the uniformly mixed brine from the brine tank 8 through the connecting pipe 204. During the extraction process, the fine filter 205 performs fine filtration of the brine, removing impurities and preventing blockages, thus ensuring smooth brine delivery and salt mist quality. After being pumped by the water pump 203, the filtered brine enters the distribution pipe 206 from its output end. The distribution pipe 206 is fixedly installed at the top of the spray chamber 3, and multiple atomizing nozzles 207 are equidistantly connected to its bottom. The brine flows within the distribution pipe 206 and is evenly distributed through the multiple atomizing nozzles 207. When the brine flows through the atomizing nozzles 207, the nozzles 207 spray the brine at high speed and disperse it into tiny salt mist particles. These salt mist particles are sprayed out from the bottom of the atomizing nozzles 207 and enter the spray chamber 3, efficiently and stably converting the brine into a uniform and fine salt mist, simulating the natural salt mist environment and ensuring the accuracy and effectiveness of the salt mist test.

[0043] Reference Figure 1 and Figure 2 The sealing assembly includes a sealing plate 13, which is rotatably connected to the middle of the front side of the test cabinet 1. A reinforcing strip 14 is fixedly connected to the top of the sealing plate 13. A fixing pin 15 passes through the left and right ends of the front side of the reinforcing strip 14. The ends of the two fixing pins 15 are respectively threaded to the left end and the middle of the front side of the test cabinet 1.

[0044] Specifically, the sealing plate 13 is rotatably connected to the middle of the front side of the test cabinet 1, allowing the sealing plate 13 to rotate flexibly around the connection point. When the test cabinet 1 needs to be closed, the sealing plate 13 is rotated to cover the opening of the test cabinet 1. At this time, the reinforcing strip 14 fixedly connected to the top of the sealing plate 13 can enhance the overall strength of the sealing plate 13. The ends of the two fixing pins 15 are aligned with the threaded holes reserved on the left side and the middle of the front side of the test cabinet 1, respectively, and then threaded connections are made. By rotating the fixing pins 15, they are tightly screwed into the test cabinet 1, ensuring that the test cabinet 1 is in a sealed state and effectively preventing salt spray from leaking into the external environment.

[0045] Reference Figure 1 , Figure 2 and Figure 3An electric control button 16 is fixedly connected to the upper middle part of the left side of the test cabinet 1, and the electric control button 16 is electrically connected to the electric telescopic rod 5; an electric control discharge valve 17 is connected to the bottom left side of the test cabinet 1, and the input end of the electric control discharge valve 17 is connected to the recovery chamber 12; a display screen 18 is fixedly connected to the right side of the front of the test cabinet 1, and the display screen 18 is electrically connected to the rotating motor 201, the water pump 203 and the electric telescopic rod 5; a control console 19 is fixedly connected to the lower middle part of the front of the test cabinet 1, and the control console 19 is electrically connected to the electric telescopic rod 5, the electric control discharge valve 17, the rotating motor 201 and the water pump 203; two triangular braces 20 are fixedly connected to the front of the test cabinet 1, and the tops of the two triangular braces 20 are designed with elasticity.

[0046] Specifically, pressing the electric control button 16 can quickly start or stop the electric telescopic rod 5. When it is necessary to fix the sample, pressing the electric control button 16 causes the electric telescopic rod 5 to move the clamping plate 6 to clamp the sample. After the test, pressing the electric control button 16 again resets the electric telescopic rod 5, simplifying the sample fixing and removal process. After the salt spray test is completed, the control console 19 controls the opening of the electric discharge valve 17, and the brine collected in the recovery chamber 12 can be discharged through the electric discharge valve 17, facilitating centralized processing of the recovered brine. The display screen 18 is connected to the rotating motor 201, water pump 203, and electric telescopic rod 5. The telescopic rod 5 is electrically connected, which can display the working status of these key components in real time, and can also intuitively obtain equipment operation information and promptly detect equipment malfunctions. The control console 19 is electrically connected to the electric telescopic rod 5, the electrically controlled discharge valve 17, the rotary motor 201 and the water pump 203, which can centrally control these components on the control console 19 to achieve precise control of each stage of the salt spray test. When the test cabinet 1 is placed, the rear side of the triangular brace 20 contacts the test cabinet 1. Through the stability principle of the triangle, the stability of the sealing plate 13 is enhanced when placed. The elastic design at the top can prevent the sealing plate 13 from being bumped.

[0047] Working principle: Inside the test cabinet 1, the spray chamber 3 on the left and the electric telescopic rod 5 on the right work together to fix the sample. The fixing rod 4 is fixed to the left side of the spray chamber 3, and its right end is connected to the output end of the electric telescopic rod 5 with clamping plates 6. When the electric telescopic rod 5 is activated, its output end extends, driving the clamping plates 6 to move and cooperate with the left clamping plate 6 to clamp and fix the sample between the two clamping plates 6. Multiple anti-slip strips 7 are fixedly connected at equal intervals inside the clamping plates 6 to increase the friction between the clamping plates 6 and the sample, ensuring that the sample will not shift during the test and guaranteeing the accuracy of the test. The brine tank 8 is fixed to the bottom right side of the inside of the test cabinet 1. An appropriate amount of salt is added to the brine tank 8 through the feeding trough 9, and a certain amount of water is injected through the water injection pipe 10. The brine tank 8 is equipped with... The atomizing mechanism 2 can mix the salt water mixture evenly to prepare salt water with the required concentration for the test. The atomized salt mist is sprayed into the spray chamber 3 to prepare for spraying the sample. The salt mist entering the spray chamber 3 is evenly diffused into the sample area to simulate the salt mist erosion in the natural environment. During the salt mist spraying process, excess salt mist and salt water flowing down from the sample surface will drip down through the drain hole 11 in the middle of the inner side of the test cabinet 1. Since the spray chamber 3, the drain hole 11 and the recovery chamber 12 are connected, the dripping salt water and salt mist will eventually flow into the recovery chamber 12 to realize the recovery of salt water and avoid waste and environmental pollution. The sealing component set at the front left end of the test cabinet 1 can ensure that the test cabinet 1 is in a sealed state during the test.

[0048] Furthermore, the output end of the rotating motor 201 is fixedly connected to the stirring blade 202, which is rotatably connected to the right side of the brine tank 8. When salt and water are added to the brine tank 8, the rotating motor 201 is started, and its output end drives the stirring blade 202 to rotate inside the brine tank 8. The rotation of the stirring blade 202 ensures that the salt and water in the brine tank 8 are fully mixed, ensuring the preparation of brine with uniform concentration, providing a stable raw material for subsequent salt spray generation. The input end of the water pump 203, which is fixedly connected to the right side of the test cabinet 1, is connected to the brine tank 8 through a connecting pipe 204. The bottom of the connecting pipe 204 penetrates the inside of the brine tank 8, and its input end is connected to a fine filter 205. After the water pump 203 is started, it generates suction. The brine, which is mixed evenly in the brine tank 8, is drawn up through the connecting pipe 204. During the extraction process, the fine filter 205 performs fine filtration on the brine to remove impurities and prevent them from causing blockages, thus ensuring smooth brine delivery and the quality of the salt mist. After being drawn up by the water pump 203, the filtered brine enters the diversion pipe 206 from its output end. The diversion pipe 206 is fixedly installed on the top of the spray chamber 3, and multiple atomizing nozzles 207 are equidistantly connected to its bottom. The brine flows in the diversion pipe 206 and is evenly distributed through the multiple atomizing nozzles 207. When the brine flows through the atomizing nozzles 207, the atomizing nozzles 207 spray the brine at high speed and disperse it into tiny salt mist particles.
