[0002] In the existing powder-liquid mixing technology, in order to improve the powder suction capacity, the measures are as follows: 1. Increase the suction force of the powder feeder; 2. Reduce the diameter of the powder conveying pipe.

[0003] However, increasing the suction force of the powder feeder will result in an increase and waste of power and cost; reducing the pipe diameter will cause the entire diameter of the pipeline in the powder transportation process to be reduced, greatly increasing the risk of blockage;

[0004] Meanwhile, as disclosed in the patent with the patent publication number CN212441090U, a self-priming powder homogenizer is disclosed. This device uses the negative pressure generated by a high-speed rotating impeller to suck powder, but it does not consider that in the case of insufficient impeller suction or a relatively low bulk density of the powder, the device will have the phenomenon of being unable to suck powder and not being able to suck all the powder.

[0005] On this basis, it is urgent to develop a rapid powder suction device for powder-liquid mixing. Content of the Utility Model

[0008] As a further improvement of the above technical solution:

[0011] Preferably, a cartridge end connected to the bottom outlet of the high-mixing bin is provided at the top of the material suction nozzle.

[0012] Preferably, a pipeline for mixing solvents and an impeller for forming negative pressure are provided inside the powder suction machine.

[0013] Preferably, one side of the powder suction machine is also connected to a solvent circulation pipeline, and the solvent circulation pipeline is directly communicated with the powder suction machine to introduce the solvent into the powder suction machine for internal circulation; after the solvent is introduced into the powder suction machine, it infiltrates the pipeline and fills the impeller at the same time, forming negative pressure.

[0014] Preferably, a gas inlet is provided at the top of the high-mixing bin, and the gas inlet is connected to an inert gas pipeline;

[0030] As Figures 1 to 2 shown, the rapid powder suction device for powder-liquid mixing in this embodiment includes a high-speed mixing bin 1, which is connected to an inert gas pipeline 3 at the top; the bottom outlet of the high-speed mixing bin 1 is connected to the top of a powder suction nozzle 4, the bottom of the powder suction nozzle 4 is connected to a blanking pipeline 5, and the powder falls into a powder suction machine 6 through the blanking pipeline 5; the pipeline in the powder suction nozzle 4 is a reduced-diameter pipeline, and the inner diameter of the reduced-diameter pipeline shows a trend of first decreasing and then increasing along the suction direction of the powder suction machine 6, and the suction of the powder suction machine 6 is amplified when passing through the reduced-diameter pipeline.

[0031] In this embodiment, the variable-diameter pipeline structure of the material suction nozzle 4 is as follows: it includes a first variable-diameter pipeline 402, a material suction pipeline 403, and a second variable-diameter pipeline 404 arranged in sequence from top to bottom; the inner diameter of the first variable-diameter pipeline 402 decreases from large to small; the inner diameter of the second variable-diameter pipeline 404 increases from small to large; the material suction pipeline 403 is a straight cylindrical pipeline, the top of the material suction pipeline 403 matches the bottom of the first variable-diameter pipeline 402, and the bottom of the material suction pipeline 403 matches the top of the second variable-diameter pipeline 404;

[0032] Further, the first variable-diameter pipeline 402, the material suction pipeline 403, and the second variable-diameter pipeline 404 are an integrated pipeline, and the whole is in the shape of an hourglass.

[0033] In this embodiment, a clamping end 401 connected to the bottom outlet of the high-speed mixer silo 1 is provided at the top of the material suction nozzle 4.

[0034] In this embodiment, a pipeline for mixing solvents and an impeller for forming negative pressure are provided inside the powder suction machine 6.

[0035] In this embodiment, one side of the powder suction machine 6 is also connected to the solvent circulation pipeline 7, and the solvent circulation pipeline 7 is directly communicated with the powder suction machine 6 to introduce the solvent into the powder suction machine 6 for internal circulation; after the solvent is introduced into the powder suction machine 6, it infiltrates the pipeline and fills the impeller at the same time, forming negative pressure.

[0036] In this embodiment, a gas inlet 2 is provided at the top of the high-speed mixer silo 1, and the gas inlet 2 is connected to the inert gas pipeline 3;

[0037] Further, the inert gas pipeline 3 introduces inert gas into the high-speed mixer silo 1 through the gas inlet 2 to remove the air in the high-speed mixer silo 1 and protect the powder material.

[0038] The working principle of the present utility model is as follows:

[0039] Based on Bernoulli's principle, when a fluid passes through a gradually reducing pipe diameter, its flow velocity increases and its hydrostatic pressure decreases, which is equivalent to increasing the powder suction negative pressure. Therefore, the present utility model adds a material suction nozzle 4. When passing through the first variable-diameter pipeline 402 first, the inner diameter of the pipeline shows a decreasing trend, reducing the risk of powder material blockage while improving the powder suction efficiency.

[0040] The working process of the present utility model is as follows:

[0041] The powder is premixed in the high - mixing bin 1 by the powder conveying system, while the solvent is circulated through the solvent circulation pipeline 7 into the powder suction machine 6. The solvent infiltrates the pipeline in the powder suction machine 6 and fills the impeller at the same time, forming a negative pressure. The inert gas enters the high - mixing bin 1 through the inert gas pipeline 3. The inert gas can protect the powder from being damaged while exhausting the air. The negative pressure generated by the impeller of the powder suction machine 6 is amplified when passing through the material suction nozzle 4, and the powder is sucked into the powder suction machine 6 through the material suction nozzle 4 to complete the powder - liquid mixing.

[0042] The structure of the utility model is reasonable, and the powder suction process is stable and efficient. A material suction nozzle 4 is added before the feed inlet of the blanking pipeline 5, and a variable - diameter pipeline is arranged inside the material suction nozzle 4. Thus, without increasing or wasting the transformation cost, the suction force of the whole device can be increased, and the efficiency of the powder suction process can be greatly improved.

[0043] The technical features of the above - described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above - described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0044] The above - described embodiments only express the implementation manners of the utility model, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
