Description

Technical Field

[0001] The invention relates to the technical field of hydrofluoric acid detection, in particular to a detection mechanism for hydrofluoric acid preparation. Background Art

[0002] Hydrofluoric acid is an aqueous solution of hydrogen fluoride gas, a clear, colorless, fuming corrosive liquid with a strong pungent odor. It is a weak acid, but extremely corrosive and can corrode metals, glass, and silicon-containing substances. When hydrofluoric acid is prepared, a testing agency is required to test the hydrofluoric acid.

[0003] The hydrofluoric acid detection mechanism in the prior art can ensure the stability of the test environment by setting the cooperation between the transmission plate, the screw rod, the transmission motor and the wind shield, increase the authenticity of the test results, and reduce the impact of the volatilized gas of hydrogen fluoride on the tester during the test;

[0004] However, in order to improve the accuracy of the test, when it is necessary to test multiple groups of hydrofluoric acid, the test personnel are required to continuously place the beaker containing hydrofluoric acid on the measuring plate, and remove the beaker from the measuring plate after the test.

After a proper amount of hydrofluoric acid is added to the beaker, as the hydrofluoric acid continues to rotate, one end of the third plug rod 72 is driven to slide from the sixth arc groove 70 and one of the fifth connecting grooves 71 to the fifth arc groove 65, thereby automatically pushing the movable plate 64 to move toward the direction close to the beaker, and then driving the cover plate 68 to move to the top of the beaker for shielding, so as to avoid the problem of hydrofluoric acid in the beaker pouring out during the transfer of the beaker, and when the beaker is transferred to the measuring disk 3, the one end of the third plug rod 72 slides in the sixth arc groove 70, and the cover plate 68 can be rotatably driven to move away from the top of the beaker, so that the detection of hydrofluoric acid can be smoothly carried out, with a simple structure and functional use.

[0046] The implementation principle of a detection mechanism for preparing hydrofluoric acid in an embodiment of the present invention is as follows: first, an empty beaker is prevented from being placed in a transfer slot 9 on a rotating disk 6 on an arc frame 10, and then the motor 7 on the mounting plate 4 is started to drive the rotating rod 8 and the rotating disk 6 to rotate as a whole, thereby driving the beaker to be transferred to the lower part of a discharge pipe 50 on the arc frame 10, and then the second cylinder 52 is started to drive the fixed pipe 55 and the limiting plate 56 to move upward as a whole through the driving sleeve 54, and the blocking block 60 and the second piston 59 are moved into the discharge barrel 48 as a whole, so that the hydrofluoric acid prepared in the storage barrel 45 flows into the measuring cylinder 49, and according to the actual needs, the screw 58 can be rotated by using the rotating disk 63 in conjunction with the scale on the transparent measuring cylinder 49, and under the limit of the limiting rod 62, The screw sleeve 61 drives the second piston 59 to move. By adjusting the distance between the second piston 59 and the first piston 57, the corresponding capacity of hydrofluoric acid can be pumped out. After pumping out, the second cylinder 52 drives the fixed tube 55 to move downward. When driving the blocking block 60 to move downward to reset the blockage, the first piston 57 moves in the measuring cylinder 49 to the bottom of the feeding tube 50, so that the feeding tube 50 and the measuring cylinder 49 are connected. The hydrofluoric acid pumped between the first piston 57 and the second piston 59 can be discharged from the feeding tube 50 to the beaker, and then the rotating disk 6 continues to rotate, driving the beaker filled with hydrofluoric acid to continue to transfer. At the same time, it drives one end of the third plug rod 72 to slide into the fifth arc groove 65, pushing the movable plate 64 to move in the direction close to the beaker, and then The cover plate 68 is driven to move to the top of the beaker for shielding, so as to prevent the hydrofluoric acid in the beaker from pouring out during the transfer process of the beaker, and one end of the second plug rod 20 is driven to slide in the second arc groove 25, driving the first plug rod 19 on the driving bar 18 to slide in the driving groove 17 in the direction away from the transfer groove 9, thereby pulling the two driving plates 12 to move towards each other on the fixing rod 13, and then driving the clamping plate 14 to clamp and fix the beaker, so as to prevent the beaker from being directly transferred to the measuring disk 3. The measuring disk 3 is unloaded due to the weight of the beaker, which causes the beaker to tilt during the transfer process, and the hydrofluoric acid is poured out. When the rotating disk 6 drives the beaker to transfer to the detection position on the measuring disk 3, the rotating disk 6 is rotated. The turntable 6 drives one end of the second plug rod 20 to slide in the third arc groove 27, thereby automatically loosening the two clamping plates 14 on the beaker. Under the action of the gravity of the beaker, the measuring disc 3 can be smoothly moved down to detect the hydrofluoric acid in the beaker. After the detection, the rotating disc 6 continues to rotate, driving the beaker from the measuring disc 3 to the arc frame 10. In the process, the one end of the second plug rod 20 is driven to slide in the fourth arc groove 29, automatically driving the clamping plate 14 to clamp the beaker, and driving the roller at one end of the lifting rod 73 to roll from the arc bar 38 to the arch bar 39. In this way, the beaker can be lifted on the measuring disc 3, so that the rotating disc 6 can smoothly transfer the beaker to the arc frame 10 again, and after the beaker is transferred to the arc frame 10,The second plug rod 20 is driven to slide one end back into the first arc groove 23, thereby automatically loosening the two clamping plates 14 on the beaker. When the beaker is transferred to the discharge port 40 on the arc frame 10, the first cylinder 42 is started to drive the push plate 44 to move toward the storage plate 41, thereby unloading the beaker onto the storage plate 41 for convenient centralized processing, thus realizing the detection of hydrofluoric acid.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
