[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0021] Reference Figure 1-4As shown, an automatic feeding sand and dust test chamber includes: a main body 1 and a feeding door 2. The feeding door 2 is movably installed on the right side of the outer surface of the main body 1 near the top. The operator opens the feeding door 2 and adds sand and dust into the test chamber 8. After feeding is completed, the feeding door 2 is closed, the motor in the motor box 4 is started, and the stirring drum 7 is rotated to stir the sand and dust in the test chamber 8, so that the sand and dust are evenly distributed and prepared for subsequent tests. The test chamber 8 is fixedly installed inside the main body 1 at the rear side of the feeding door 2. The mounting plate 5 is fixedly installed in the middle of the interior of the test chamber 8. The stirred sand and dust falls into the feeding hopper 9. The vibrator 15 on one side of the feed hopper 9 is activated to prevent sand and dust from accumulating in the feed hopper 9 and to ensure that the sand and dust enter the first connecting pipe 10 smoothly. The weighing sensor 16 monitors the weight of the sand and dust in the feed hopper 9 in real time to provide data for subsequent precise control of the feeding amount. The motor box 4 is fixedly installed at the top center of the outer surface of the mounting plate 5, and the motor box 4 is equipped with a motor. The motor output end inside the motor box 4 passes through the motor box 4 and is fixedly installed with a stirring auger 7 on the outer surface of the mounting plate 5. The feed hopper 9 is fixedly installed at the bottom of the outer surface of the test chamber 8, and the shaft surface of the stirring auger 7 is set on the feed hopper 9. The ultraviolet lamp 6 is installed at the bottom of the outer surface of the mounting plate 5. The first connecting pipe 10 is fixedly installed at the bottom of the outer surface of the feed hopper 9. The second connecting pipe 11 is fixedly installed at the bottom of the shaft surface of the first connecting pipe 10. The fan 12 is fixedly installed on one side of the second connecting pipe 11 at the bottom of the interior of the main body 1. The sand and dust enter the first connecting pipe 10 from the feed hopper 9. The humidity sensor 17 monitors the humidity of the sand and dust in real time. When the humidity exceeds the set value, the dehumidification device 18 is activated to reduce the humidity of the sand and dust, ensuring that the humidity of the test environment meets the requirements. The sand and dust continue to enter the second connecting pipe 11, and the fan 12 is activated to transport the sand and dust through the second connecting pipe 11 to the conveying pipe 13.In this process, the heating tube 20 installed in the second connecting pipe 11 can heat the sand and dust according to the test requirements and adjust the temperature of the sand and dust. The pressure sensor 21 monitors the pressure in the second connecting pipe 11 in real time to ensure the pressure is stable during the conveying process. The output end of the fan 12 is connected to the inside of the second connecting pipe 11. A humidity sensor 17 is fixedly installed at the top of the inside of the first connecting pipe 10. The flow regulating valve 14 on the conveying pipe 13 can adjust the flow rate of the sand and dust according to the test requirements, so that an appropriate amount of sand and dust returns to the test chamber 8 through the conveying pipe 13 to form a sand and dust cycle. In the test chamber 8, the sand and dust test the products placed inside, simulating the impact of natural wind and sand climate on the products. A dehumidifying device 18 is electrically installed at the bottom of the outer surface of the humidity sensor 17. Several sets of mounting blocks 19 are fixedly installed inside the second connecting pipe 11. Several sets of mounting blocks 19 are fixedly installed on opposite sides. A pressure sensor 21 is fixedly installed inside the heating tube 20 and near the front end of the second connecting tube 11. A conveying tube 13 is fixedly installed at the front end of the shaft surface of the second connecting tube 11. A flow regulating valve 14 is provided on the shaft surface of the conveying tube 13, and the top end of the shaft surface of the conveying tube 13 is connected to the test chamber 8. A vibrator 15 is fixedly installed on one side of the outer surface of the feed hopper 9. A weighing sensor 16 is fixedly installed at the bottom end of the outer surface of the feed hopper 9. A control board 3 is electrically installed on the front end of the outer surface of the main body 1. The operator controls the operation of the entire equipment through the control board 3, including starting and stopping the motor, adjusting the wind speed of the fan 12, setting the temperature of the heating tube 20, and adjusting the flow of the flow regulating valve 14. The control board 3 can also display the data collected by the humidity sensor 17, the weighing sensor 16, the pressure sensor 21, etc. in real time, so that the operator can keep track of the operating status of the equipment and the test environment parameters at any time.
[0022] Working principle and implementation method: The operator first opens the feed door 2 at the top right side of the outer surface of the main body 1 and adds sand and dust into the internal test chamber 8. After the feeding is completed, the feed door 2 is closed. At this time, the motor box 4 installed on the mounting plate 5 inside the test chamber 8 is started. Its internal motor drives the stirring drum 7 to rotate, stirring the sand and dust in the test chamber 8 to promote uniform distribution of the sand and dust. The stirred sand and dust falls into the feed hopper 9 at the bottom of the test chamber 8. The vibrator 15 on one side of the feed hopper 9 is started to prevent the sand and dust from accumulating and ensure that it enters the first connecting pipe 10 smoothly. At the same time, the weighing sensor 16 at the bottom of the feed hopper 9 monitors the weight of the sand and dust in real time. The humidity of the sand and dust in the first connecting pipe 10 is monitored by the humidity sensor 17 at the top. When the humidity exceeds the limit, the dehumidification device 18 electrically connected below is started to regulate the humidity. Then the sand and dust enters the second connecting pipe 11. The fan 12 located on one side of the bottom inside the main body 1 is started to transport the sand and dust to the conveying pipe 13. During the process, the heating pipe 20 installed in the second connecting pipe 11 heats the sand and dust as needed, and the pressure sensor 21 monitors the pressure inside the pipe in real time. Finally, the flow regulating valve 14 on the delivery pipe 13 adjusts the sand and dust flow according to the test requirements, so that the sand and dust circulate back to the test chamber 8 to carry out simulated wind and sand climate test on the products in the chamber. The operator controls the operation of the equipment, such as the motor, fan 12, heating tube 20 and flow regulating valve 14, through the control board 3 at the front end of the main body 1 throughout the process, and can view the data of each sensor in real time to grasp the equipment status and test environment parameters.
