[0023] The top of the tank discharge pipe 5 passes through the top of the solvent mixing tank 3, and a vacuum suction pump 7 is provided at the top of the tank discharge pipe 5. The top of the vacuum suction pump 7 is connected to the feeding pipe 4. A top water inlet pipe 8 is inserted at the top of the solvent mixing tank 3, and a tank spray ball 9 is installed at the bottom end of the top water inlet pipe 8. A first sanitary ball valve 10 is provided at the top of the top water inlet pipe 8. A liquid dispensing tank inlet 11 is provided on the side of the top of the solvent mixing tank 3, and a glass window 12 is provided on the side of the solvent mixing tank 3. An end grid 13 is provided at the bottom end of the tank discharge pipe 5, and a screen 14 is provided on the side of the top of the solvent mixing tank 3. A feed pipe 15 is connected to the screen 14, and a second sanitary ball valve 16 is provided at the top of the feed pipe 15. A sight glass lamp 17 is provided on the top of one side of the solvent mixing tank 3, a tank bottom agitator 18 is provided on the side of the bottom of the solvent mixing tank 3, and a tank bottom discharge valve 19 is provided on the side of the tank bottom agitator 18.

[0024] Embodiment 2: The difference between this embodiment and embodiment 1 is that the screen 14 is composed of a screen frame and a mesh frame.

[0025] The screen 14 can be more conveniently assembled and disassembled on the solvent mixing tank 3 .

[0026] Embodiment 3: The difference between this embodiment and embodiment 1 is that the bottom opening of the terminal grille 13 is provided with a plurality of holes.

[0027] The powder material entering the discharge pipe 5 in the tank can be better dispersed through the end grid 13, avoiding the agglomeration of the material under the liquid surface, which is not conducive to further dispersion or dissolution of the powder material in the solvent.

[0028] Embodiment 4: The difference between this embodiment and embodiment 1 is that the top end of the tank bottom agitator 18 extends into the solvent mixing tank 3 .

[0029] The end of the tank bottom agitator 18 can better mix the powder entering the solvent mixing tank 3.

[0030] In this embodiment, since light fine powder or ultrafine powder easily causes dust to fly when feeding, on the one hand, it pollutes the operating environment and is not conducive to the cleaning of equipment and site and the clean maintenance of the environment; on the other hand, the dust is easily inhaled by the human body, which has an adverse effect on the health of the operator.

[0031] In summary, in specific implementation, when the user needs to add the powder stored in the fine powder storage cylinder 2 to the liquid in the solvent mixing tank 3 for dispersion and mixing, the user first needs to connect the feeding pipe 4 connected to the top of the fine powder storage cylinder 2 with the vacuum suction pump 7 at the top of the discharge pipe 5 in the tank, and start the vacuum suction pump 7. The powder stored in the fine powder storage cylinder 2 can be sucked into the solvent mixing tank 3, and since the bottom end of the discharge pipe 5 in the tank is provided with an end grid 13, the powder can be preliminarily dispersed under the dispersing action of the end grid 13, avoiding the agglomeration of materials below the liquid surface, which is not conducive to further dispersion or dissolution of the powder material in the solvent.

[0032] A tank bottom agitator 18 is provided at the bottom of the solvent mixing tank 3, which can mix and stir the powder and liquid added to the bottom of the solvent mixing tank 3, so that the mixing between the powder and the liquid is more sufficient, and the quick connector 6 can facilitate the user to clearly observe the mixing condition of the powder inside the solvent mixing tank 3, and the sight glass light 17 can provide effective lighting for observation, and the top water inlet pipe 8 connected to the spray ball 9 in the tank can be connected to an external water source for adding solvent to the solvent mixing tank 3. The spraying of the spray ball 9 in the tank can make the mixing between the powder and the solvent added to the solvent mixing tank 3 more convenient.

[0033] This "solvent dispersion and dust-free feeding device" uses a vacuum system to transfer "light fine powder or ultrafine powder" in a closed manner to the liquid surface of the solvent system that has been added in advance in the tank. The solid powder is pre-dispersed through the pipe grid to prevent the solid powder from agglomerating under the liquid surface. At the same time, the agitator at the bottom of the tank is used for secondary rapid dispersion to ensure that the solid material under the liquid surface is fully infiltrated and dispersed, thereby avoiding dust flying during dry feeding of "light fine powder or ultrafine powder", avoiding the overflow of solid material, and ensuring the cleanliness of the feeding environment.

[0034] This system can also be used as a solution preparation tank for solution preparation and metering.

[0035] This system can be used as high tank, and reaction kettle, extraction tank and so on, to realize the dust-free addition of material and preparation and metering addition of solution.
