Description

Technical Field

[0001] The utility model relates to the technical field of smoke test chambers, in particular to a pneumatic cleaning device for a smoke test chamber. Background Technique

[0002] A smoke test chamber, also known as a salt spray test chamber, is mainly used to evaluate the ability of materials and their protective layers to resist salt spray corrosion. This device simulates harsh salt spray environmental conditions to test the corrosion resistance of materials, and thus is widely used in the corrosion resistance detection of parts, electronic components, protective layers of metal materials, and various industrial products.

The control box is arranged on one side of the box body, and a sealing member is installed below the box cover close to the shell. Through the setting of the sealing member, the sealing performance of the box body can be improved, and it will not be affected by the external environment during the test, resulting in inaccurate testing. The upper end of the bracket is provided in the form of a clamping block, and the placement rack is connected and installed at the upper end of the bracket by a buckle structure. The first card slot and the second card slot are set corresponding to the bottom sizes of the collection cup and the test piece. The placement rack is fixed above the bracket through the buckle structure. When it needs to be cleaned after a test, at this time, through the action of the spring, the clamping ring retracts inward to loosen both ends of the placement rack.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 , a pneumatic cleaning device for a smoke test chamber in this embodiment includes a test chamber body 1, a base 2 is arranged at the bottom of the test chamber body 1, a water collecting tray 3 is rotatably installed inside the test chamber body 1, an auxiliary mechanism 4 is arranged on the top of the water collecting tray 3, and a brine delivery assembly and a water source delivery assembly are arranged inside the base 2.

[0022] The auxiliary mechanism 4 includes a box body 401, the box body 401 is fixedly installed on the top of the test chamber body 1, a motor 402 is fixedly installed on the right inner wall of the box body 401, a worm 403 is fixedly installed at the output shaft of the motor 402, a turbine 404 is meshed on the outer surface of the worm 403, a vertical pipe 405 is fixedly installed inside the turbine 404, a rotary joint 406 is arranged at the top of the vertical pipe 405, and a connecting pipe 407 is arranged at the top of the rotary joint 406.

[0023] The function of the auxiliary mechanism 4 is to drive the water collecting tray 3 to rotate 360 degrees, so that brine or water source is sprayed out from the rotating water collecting tray 3, realizing all-round flushing, and enabling the brine to be evenly distributed in the test chamber body 1, improving the test accuracy.

[0024] During cleaning, when the water source passes through the liquid storage tank 601, the second hydraulic pump 602, the second liquid suction pipe 603, the second liquid delivery pipe 604, the rotary joint 406, the connecting pipe 407 and the vertical pipe 405 and enters the water collecting tray 3, under the operation of the motor 402, the worm 403 is driven to rotate. The worm 403 drives the turbine 404 to rotate, and the turbine 404 drives the vertical pipe 405 to rotate, thereby driving the water collecting tray 3 to rotate. The water source is sprayed everywhere inside the test chamber body 1 through the rotating spray head 301.

[0025] During the test, the water source passes through the brine tank 501, the first hydraulic pump 502, the first liquid suction pipe 503, the first liquid delivery pipe 504, the rotary joint 406, the connecting pipe 407 and the vertical pipe 405 and enters the water collecting tray 3, and is sprayed out through the rotating water collecting tray 3. For the structures and installation methods not described for the test chamber body 1, the structures and installation methods of the existing technology are adopted.

[0026] To improve the stability of the water collecting tray 3 during rotation, a limiting ring located on the outer surface of the water collecting tray 3 is provided at the top of the test chamber body 1. At the same time, a guide wheel 302, a cylinder body and a guide groove are also provided. When the water collecting tray 3 rotates, it drives the guide wheel 302 to slide stably in the guide groove.

[0027] To enable the cleaning water source to drain smoothly from the inside of the test chamber body 1, leakage holes and inclined sliding platforms are uniformly opened inside the placing plate 7. The waste water can slide along the sliding platform from the flowing water holes and be discharged from the waste discharge pipe, preventing the waste water from accumulating inside the test chamber body 1.

[0028] During implementation, the following steps are carried out for operation:

[0029] 1) During the test, place the items on the placing plate 7, and spray the brine in the brine tank 501 onto the items through the brine delivery assembly;

[0030] 2) When the test is over and the inside of the test chamber body 1 needs to be cleaned, convey the cleaning liquid or water source to the water collecting tray 3 through the water source delivery assembly;

[0031] 3) At the same time, drive the water collecting tray 3 to rotate through the auxiliary mechanism 4, and spray the water source everywhere inside the test chamber body 1 for comprehensive flushing;

[0032] 4) Finally, the waste liquid slides along the leakage holes on the placing plate 7 along the sliding platform and is discharged from the drain pipe.

[0033] In summary, for the pneumatic cleaning device of this smoke test chamber, by setting the auxiliary mechanism 4, the water collecting tray 3 can be rotated. During the rotation process, the brine or cleaning liquid can be sprayed everywhere inside the test chamber body 1 for comprehensive flushing of the inside of the test chamber body 1, and the brine can be evenly sprayed inside the test chamber body 1, improving the test accuracy.
