Description

Technical Field

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

[0002] Chinese patent document CN218350073U discloses a salt spray testing device, comprising a chamber assembly, a chamber cover, an observation window, an electrical control cabinet, control buttons, and a liquid supply assembly. In this invention, the chamber assembly places the device to be tested on a placement plate, the chamber cover seals the upper part of the test chamber, and the liquid supply assembly provides salt solution to the atomizing nozzle. The salt spray is then delivered into the test chamber for salt spray testing via the atomizing nozzle. The device features a simple structure, convenient and quick operation, facilitates maintenance, and reduces operating costs. The control buttons control the metering pump and solenoid valve, allowing the metering pump to deliver a fixed amount of salt solution to the atomizing nozzle, ensuring accurate measurement of the test salt solution and guaranteeing the testing device's accuracy. The observation window, located on the chamber cover, allows operators to easily observe the interior of the test chamber, enabling them to perform appropriate operations based on the internal conditions and improving the device's efficiency.

[0003] The salt spray test device mentioned above cannot treat the salt spray after the test is completed. If it is discharged directly, the salt in the salt spray will spread on the floor, walls, instruments and equipment in the test chamber, causing corrosion and pollution to other items in the surrounding area, and may even endanger the health of the surrounding experimental personnel.

Two sets of moving blocks 1003 are threadedly connected to the outer wall of the bidirectional threaded rod 1002. The opening and closing mechanism 10 can control the opening and closing of the opening and closing plate 11, so that the salt spray that settles to the bottom of the inner side of the test shell 2 can be absorbed by the clean water inside the absorption box 12 and the activated carbon inside the fixed shell 13. Compared with direct discharge, this reduces the corrosion of the ground, walls, instruments and equipment in the test chamber by salt spray and improves the health and safety of the surrounding experimental personnel.

[0025] The blower mechanism 3 includes a motor 301, a rotating rod 302, and fan blades 303. The motor 301 is fixedly installed on the top of the test housing 2. The output shaft of the motor 301 extends into the interior of the test housing 2 and is fixedly installed on the rotating rod 302. Multiple sets of fan blades 303 are fixedly installed on the outer wall of the rotating rod 302. The blower mechanism 3 can accelerate the salt spray to settle to the bottom of the inner side of the test housing 2.

[0026] The front side of the mounting plate 1 has a strip-shaped opening for two sets of movable blocks 1003 to slide. One end of each set of movable blocks 1003 extends into the interior of the mounting plate 1 through the strip-shaped opening and is fixedly connected to a set of opening and closing plates 11.

[0030] Working principle: When an experiment is required, open the door on the front of the test housing 2, place the experimental object on the placement plate 15, close the door, and start the suction pump 5. The suction pump 5 transports the saline solution inside the saline tank 4 to the delivery pipe 6, and then through the delivery pipe 6 into the spray box 7, where it is atomized and sprayed out through multiple sets of atomizing nozzles 8. The experimental condition of the object can be observed through the glass on the front of the test housing 2. After the experiment is completed, start the motor 1001. The output shaft of the motor 1001 rotates, driving the bidirectional threaded rod 1002 to rotate. 2. Rotation drives two sets of moving blocks 1003 to move laterally, thereby controlling the opening of two sets of opening and closing plates 11, controlling the start motor 301. The output shaft of motor 301 rotates, driving the rotating rod 302 to rotate. The rotating rod 302 rotates, driving multiple sets of fan blades 303 to rotate and generate wind, accelerating the salt spray to settle to the bottom of the inner side of the test shell 2. The salt spray is absorbed by the clean water in the absorption box 12 and the activated carbon in the fixed shell 13. After a period of time, the door is opened, the absorption box 12 is snapped off from the mounting plate 1, and the absorption box 12 is taken out, and the salt water in the absorption box 12 is discharged.
