Description

Technical Field

[0001] The present invention relates to the field of environmental chamber control devices, and particularly relates to a multi-factor environmental chamber control device. Background Art

[0002] An environmental chamber is a facility designed for scenarios such as experiments, production, and testing that require a specific environment. It uses technical means to precisely control parameters such as air, temperature, humidity, light, and noise to meet specific environmental requirements. The main function of the environmental chamber is to provide stable and reliable environmental conditions for activities such as experiments, production, and testing, and to ensure the accuracy and repeatability of the results.

[0003] In the prior art, only a single object can be placed in the environmental chamber for testing. And after each test is completed, the inside needs to be cleaned. For example, when conducting salt spray environment experiments with different concentrations on a single product, the environmental chamber needs to simulate different concentrations and then conduct the test, or multiple environmental chambers are used to simulate the environment for testing respectively. Both methods require a large testing cost, and the testing efficiency needs to be improved.

[0004] Therefore, it is very necessary to propose a multi-factor environmental chamber control device to solve the above problems. Summary of the Invention

[0010] Preferably, one end of the mixing chamber is connected to a water pipe. There are multiple second spray heads, and multiple second spray heads are all communicated with the inside of the corresponding discharge chamber. One side of the environmental chamber body is hinged with a hatch.

[0011] Preferably, a leakage hole is opened at the top end of the collection tank. The leakage hole is communicated with the inside of the mixing chamber. The mixing mechanism includes a fixed plate and a sliding plate. The fixed plate and the sliding plate are respectively located on both sides of the bottom end of the leakage hole, and the fixed plate is fixed inside the mixing chamber. The sliding plate is slidably installed inside the mixing chamber. A spring is fixed between the sliding plate and the fixed plate. A filter screen is installed at the bottom end inside the leakage hole. A cleaning brush is fixed at the top end of the sliding plate, and the cleaning brush is attached to the inner wall of the top end of the mixing chamber. Through holes for liquid to pass through are opened on both the sliding plate and the fixed plate. The fixed plate is distributed in the direction close to the second pump body.

[0012] Preferably, a storage tank is fixedly connected to the top end of the environmental chamber body. A simulation chamber is opened inside the environmental chamber body. Multiple descending partition plates are installed at intervals up and down in the simulation chamber, and the multiple descending partition plates divide the inside of the simulation chamber into multiple sub-regions. Multiple first spray heads are fixed at the top end of the simulation chamber. One side of the storage tank is provided with a first pump body. The first pump body is fixed on the top end of the storage tank. The storage tank is connected to the first pump body through a suction pipe. The first pump body is connected to the first spray heads through an output pipe;

[0013] A waste discharge port is opened at the bottom end of the simulation chamber. The waste discharge port is connected to a waste liquid collection tank. The waste liquid collection tank is arranged at the bottom end inside the environmental chamber body.

[0014] Preferably, the multi-layer environmental simulation system further includes electric heating tubes, and the electric heating tubes are fixedly installed on the inner walls of the corresponding sub-regions.

[0015] Preferably, the environmental monitoring system includes a temperature sensor, a humidity sensor and a concentration sensor.

[0019] The technical effects and advantages of the present invention are as follows:

[0020] 1. In the actual operation of the present invention, the salt mist falling after spraying is collected by the collection tank and enters the interior of the mixing chamber. The water source is transported into the mixing chamber through the water pipe and mixed with the collected salt mist, thereby reducing the concentration of the collected salt mist. Moreover, the addition of the water source can also make up for the total amount of liquid lost during spraying. Through the arrangement of heights, the spraying concentration of the salt mist can be gradually reduced from high to low, so as to obtain test data of different concentrations. The amount of salt mist liquid used is low, reducing the test cost. Different concentration tests can be completed in one environmental chamber, reducing the test time.

[0021] 2. Since the higher concentration salt mist sprayed for the first time and partially supplemented water source are always used from top to bottom, the purpose of recycling is achieved, improving environmental protection.

[0022] 3. Through the combined use of the descending partition plate, the second nozzle, and the first nozzle, other corrosive liquids can be sprayed to achieve the test purpose. At the same time, when the salt mist spraying is completed, by only inputting water source, the interior of the descending partition plate and the sub-regions can be cleaned by the water source input, and no additional structure and personnel are required for cleaning.

[0023] 4. The descending partition plate divides the interior of the simulation chamber into multiple sub-regions. Each sub-region is blocked by the descending partition plate, which can prevent the spraying liquids from contacting each other and ensure the accuracy of the test data of the parts in each sub-region.

[0024] 5. In the actual operation of the present invention, when the collected salt mist liquid enters the interior of the mixing chamber, the salt mist liquid will pass through the through holes of the sliding plate and the fixed plate. Through the blocking of the sliding plate and the fixed plate, the impact force of the salt mist liquid entering can be slowed down. When the water source inside the water pipe enters or the second pump body sucks the liquid, the impact force of the water source from left to right will squeeze the sliding plate. The sliding plate squeezes the spring, and the cleaning brush at the top of the sliding plate will rub against the filter screen, thereby removing the adhered impurities at the bottom of the filter screen and avoiding clogging the leakage holes. At the same time, the sliding plate moving left and right will push the liquid and the water source back and forth, facilitating the mixing of the liquid and the water source.

[0025] 6. The concentration sensor can monitor the mixing concentration of the liquid inside the mixing chamber in real time. When the concentration reaches an appropriate value, the second solenoid valve is activated to allow the mixed liquid to be suctioned by the second pump body, and at the same time, the first solenoid valve is closed to prevent excess water from entering.

[0033] The present invention provides a multi-factor environmental chamber control device as shown in Figures 1 to 6 which includes an environmental chamber body 1. Inside the environmental chamber body 1, there are multiple layers of environmental simulation systems, environmental monitoring systems, exhaust systems and a controller. The controller is respectively connected to the corresponding multiple layers of environmental simulation systems, environmental monitoring systems and exhaust systems;

[0034] The multi-layer environmental simulation system includes a reduction baffle 13. A simulation chamber 11 is provided inside the environmental chamber body 1, and a plurality of reduction baffles 13 divide the interior of the simulation chamber 11 into multiple sub-regions. There are multiple reduction baffles 13 arranged vertically. At the bottom of each of the multiple reduction baffles 13, a second spray head 14 is provided. The reduction baffle 13 below collects the salt mist sprayed by the second spray head 14 above, and after weakening the collected salt mist concentration, sprays it again.

[0035] The multi-layer environmental simulation system can form a simulation environment within the sub-region for part testing.

[0036] Through the division by the reduction baffle 13, the interior of the simulation chamber 11 is divided into multiple sub-regions. Multiple parts that need to be tested in a simulated environment can be placed in the multiple sub-regions. The salt mist sprayed from the top can be collected by the corresponding reduction baffle 13 below, and after weakening, it is discharged again, achieving the purpose of recycling. Moreover, the salt mist with weakened concentration and the salt mist with unweakened concentration can be used for comparison. By spraying multiple parts of the same model with salt mist of different concentrations, the corrosion degree test results of the parts under different concentrations of salt mist can be obtained.

[0037] Specifically, a storage tank 3 is fixedly connected to the top end of the environmental chamber body 1. A plurality of reduction baffles 13 are installed at intervals up and down in the simulation chamber 11. A plurality of first spray heads 12 are fixed to the top end of the simulation chamber 11. One side of the storage tank 3 is provided with a first pump body 4. The first pump body 4 is fixed to the top end of the storage tank 3. The storage tank 3 is connected to the first pump body 4 through a suction pipe, and the first pump body 4 is connected to the first spray heads 12 through an output pipe.

[0038] In the actual operation of the present invention, a liquid to be simulated, such as a corrosive liquid like salt solution or acid solution, can be input into the storage tank 3. Due to the suction effect of the first pump body 4, the liquid inside the storage tank 3 can be pumped into the first spray heads 12, and the first spray heads 12 spray it and sprinkle it on the surface of the parts placed on the reduction baffle 13.

[0039] A collection groove 24 is opened at the top end of the reduction baffle 13, and a mixing chamber 19 for collecting salt mist is provided inside the reduction baffle 13. A mixing mechanism is arranged in the mixing chamber 19. A discharge chamber 20 is provided below the mixing chamber 19. A pipe 21 is connected between one end of the discharge chamber 20 and the mixing chamber 19. Two pipes 21 are connected to a second pump body 18, and the two pipes 21 are respectively connected to the inlet and outlet of the second pump body 18. The second pump body 18 is fixed to the outside of the environmental chamber body 1. Second solenoid valves 31 are provided on both of the two pipes 21. A leakage hole 25 is opened at the top end of the collection groove 24, and the leakage hole 25 is internally connected to the mixing chamber 19. One end of the mixing chamber 19 is connected to a water pipe 9, and the water pipe 9 is connected to a water source.

[0040] Support rods 16 are fixed at the top of the descending partition plate 13 and at the four corners of the bottom end of the simulation cavity 11, and a placement net 17 is fixed at the top ends of the four support rods 16.

[0041] In the actual operation of the present invention, the test parts can be placed on the placement net 17 to prevent the test parts from being directly placed in the collection tank 24, which may affect the collection of liquid.

[0042] In the actual operation of the present invention, the salt mist falling after spraying is collected by the collection tank 24 and enters the interior of the mixing cavity 19. The water source is transported into the interior of the mixing cavity 19 through the water pipe 9 and mixed with the collected salt mist, thereby reducing the concentration of the collected salt mist. Moreover, the addition of the water source can also make up for the total amount of liquid lost during spraying. For example, the concentration of the salt mist sprayed by the first nozzle 12 is 60%. Through the mixed water source, the salt mist concentration is reduced to 50%. Then, the second pump body 18 is started to suck, and finally it is discharged from the second nozzle 14 at the bottom end of the descending partition plate 13. Through the arrangement of heights, the spraying concentration of the salt mist can be gradually reduced from high to low, so as to obtain test data of different concentrations. The amount of salt mist liquid used is low, reducing the test cost. Different concentration tests can be completed in one environmental chamber 1, reducing the test time.

[0043] Since the higher concentration salt mist sprayed for the first time and partially supplemented water source are always used from top to bottom, the purpose of recycling is achieved, improving environmental protection.

[0044] Through the coordinated use of the descending partition plate 13, the second nozzle 14, and the first nozzle 12, other corrosive liquids can be sprayed to achieve the test purpose. At the same time, after the salt mist spraying is completed, by only inputting the water source, the interior of the descending partition plate 13 and the sub-regions are cleaned by the input water source, and no additional structure and personnel are required for cleaning.

[0045] The descending partition plate 13 divides the interior of the simulation cavity 11 into multiple sub-regions. Each sub-region is blocked by the descending partition plate 13, which can prevent the spraying liquids from contacting each other and ensure the accuracy of the test data of the parts in each sub-region.

[0046] The mixing mechanism includes a fixed plate 32 and a sliding plate 22. The fixed plate 32 and the sliding plate 22 are respectively located on both sides of the bottom end of the leakage hole 25, and the fixed plate 32 is fixed inside the mixing cavity 19. The sliding plate 22 is slidably installed inside the mixing cavity 19. A spring 23 is fixed between the sliding plate 22 and the fixed plate 32. A filter screen is installed at the bottom end inside the leakage hole 25. A cleaning brush is fixed at the top end of the sliding plate 22, and the cleaning brush is attached to the inner wall of the top end of the mixing cavity 19. Through holes for liquid passage are formed on both the sliding plate 22 and the fixed plate 32, and the fixed plate 32 is distributed in the direction close to the second pump body 18.

[0047] In the actual operation of the present invention, when the collected salt spray liquid enters the interior of the mixing chamber 19, the salt spray liquid will pass through the through holes of the sliding plate 22 and the fixing plate 32. Through the blocking of the sliding plate 22 and the fixing plate 32, the impact force of the salt spray liquid entering can be slowed down. When the water source inside the water pipe 9 enters or the second pump body 18 sucks the liquid, the impact force of the water source from left to right will squeeze the sliding plate 22. The sliding plate 22 squeezes the spring 23, and the cleaning brush at the top of the sliding plate 22 will rub against the filter screen, thereby removing the adhered impurities at the bottom of the filter screen, avoiding clogging of the leakage holes 25. At the same time, the sliding plate 22 moving left and right will push the liquid and the water source back and forth, facilitating the mixing of the liquid and the water source.

[0048] The multi-layer environment simulation system further includes an electric heating tube 15. The electric heating tube 15 is fixedly installed on the inner wall of the corresponding sub-region. The electric heating tube 15 can change the temperature inside the corresponding sub-region. By adjusting the same temperature or different temperatures in multiple sub-regions, different test data can be obtained.

[0049] The environment monitoring system includes a temperature sensor 27, a humidity sensor 28 and a concentration sensor 30. The concentration sensor 30 is fixed at the top end inside the mixing chamber 19. The temperature sensor 27 and the humidity sensor 28 are fixed on the inner walls of the corresponding sub-regions. And the temperature sensor 27, the humidity sensor 28 and the concentration sensor 30 are all connected to the controller. The controller is connected to the electric heating tube 15, and the controller is connected to the first solenoid valve 10, the second solenoid valve 31, the first pump body 4 and the second pump body 18.

[0050] The temperature sensor 27 and the humidity sensor 28 are used to monitor the temperature and humidity data in each sub-region in real time, avoiding the situation that the temperature and humidity do not meet the test requirements.

[0051] It should be noted that cameras can be installed in each sub-region for taking pictures or monitoring the parts during the test.

[0052] The concentration sensor 30 can monitor the mixing concentration of the liquid inside the mixing chamber 19 in real time. When the concentration reaches an appropriate value, the second solenoid valve 31 is started, so that the mixed liquid can be sucked by the second pump body 18, and at the same time, the first solenoid valve 10 is closed to prevent the excess water source from entering.

[0053] A plurality of second nozzles 14 are provided. The plurality of second nozzles 14 are all communicated with the interior of the corresponding discharge chamber 20. One side of the environmental chamber body 1 is hinged with a chamber door 2. A waste discharge port 29 is opened at the bottom end of the simulation chamber 11. The waste discharge port 29 is connected to a waste liquid collection box. The waste liquid collection box is arranged at the bottom end inside the environmental chamber body 1.
