[0002] A penetrant is a chemical that can reduce the surface tension or interfacial tension of a liquid. It can make solid materials easier to be wetted, so that the substances to be penetrated can penetrate into the penetrated substances. During the preparation process of the penetrant, various proportioned raw materials need to be dropped into the reaction kettle. In this process, a dropping device is required.

[0034] Specifically, the connection groove 10 can facilitate the connection between the dropper 6, the fixed box 2 and the reaction kettle 1;

[0035] In this embodiment, the sealing cover 3 is fixed to the top of the fixed box 2 by screws. The electric push rod 5 is fixed to one side of the fixed box 2 by a bracket. The movable block 7 is placed in the fixed box 2. When the movable block 7 is in contact with the side of the inner wall of the fixed box 2 corresponding to the electric push rod 5, the bottom of the quantitative groove 8 is aligned with the dropper 6. When the movable block 7 is in contact with the other side of the inner wall of the fixed box 2, the top of the quantitative groove 8 is aligned with the bottom of the storage tank 4;

[0036] Specifically, the quantitative groove 8 can facilitate the determination of the proportion of raw materials;

[0038] Specifically, the mounting rod 902 can facilitate the connection between the movable block 7 and the electric push rod 5;

[0039] In this embodiment, several groups of threads are provided at the inserted end of the mounting rod 902. The threaded hole 904 is adapted to the inserted end of the mounting rod 902. The inserted end of the mounting rod 902 is threadedly connected to the threaded hole 904. There are several groups of the fixed boxes 2 in total, and the sizes of the metering grooves 8 in the several groups of fixed boxes 2 are different;

[0040] Specifically, the threaded hole 904 facilitates the connection between the mounting rod 902 and the movable block 7.

[0041] The working principle and usage process of the present utility model: The operator first checks whether the relevant components are installed in the correct positions, selects a dropper 6 with a suitable diameter for each group of fixed boxes 2 according to the requirements for preparing the penetrant, removes one group of the sealing covers 3, rotates the mounting rod 902 and moves the movable block 7 in the direction away from the mounting rod 902 at the same time, so that the threaded connection between the movable block 7 and the mounting rod 902 can be separated, and the movable block 7 can be taken out from the fixed box 2, thus completing the disassembly of the movable block 7. Moving the dropper 6 upward to make the dropper 6 separate from the reaction kettle 1 and the fixed box 2 can complete the disassembly of the dropper 6. Reversing the above operations can complete the installation of the adapted dropper 6. The operations for the remaining several groups of fixed boxes 2 are the same as above. When droppers 6 with different diameters are installed at the connection groove 10, since the silicone member 11 combined with the elastic block 12 has good elasticity, the silicone member 11 is displaced by the extrusion of the dropper 6, and a circular hole formed between the corresponding two silicone members 11 is adapted to the dropper 6. And due to the rebound effect of the elastic block 12, the silicone member 11 will closely adhere to the dropper 6, which can limit and fix the dropper 6. The dropper 6 will not shake randomly, and the replacement of the dropper 6 is relatively convenient, which can meet the different dropping speed requirements during the preparation of the penetrant and improve the applicability of the dropper 6 of the equipment;

[0042] During the use process, different raw materials are stored in each storage tank 4. When it is necessary to drop the raw materials, the corresponding electric push rod 5 pushes the movable block 7 so that the movable block 7 is attached to the side of the inner wall of the fixed box 2 away from the mounting hole 901. At this time, the metering groove 8 is aligned with the bottom of the storage tank 4, and the raw materials in the storage tank 4 will fill the metering groove 8. The electric push rod 5 pulls the movable block 7 to make the movable block 7 reset and attach to the other side of the inner wall of the fixed box 2. At this time, the metering groove 8 is aligned with the top of the dropper 6. The metering groove 8 can gradually drop the raw materials with a quantitative ratio into the reaction kettle 1 through the dropper 6. When it is necessary to clean the movable block 7 later, the disassembly and assembly operations of the movable block 7 are the same as above. The movable block 7 is relatively easy to be taken out from the fixed box 2, which is convenient for the separate cleaning of the movable block 7.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
