[0012] The utility model has the advantages of uniform mixing and high safety through the cooperation of the throat, the nozzle, the first ball valve, the feed pipe and the dredging mechanism. When mixing, the pumped liquid is transported to the inside of the throat. At this time, the high-speed flowing liquid forms a negative pressure through the throat, and the dry powder inside the feed pipe is sucked into the throat, so that the liquid and the dry powder are quickly mixed, thereby improving efficiency and safety.

[0017] See also Figure 1-Figure 3 A jet pump device suitable for adding dry powder for liquid preparation includes a throat 1, a nozzle 2 is fixedly connected to the right side of the inner cavity of the throat 1, a first ball valve 3 is connected to the right side of the top of the throat 1, a feed pipe 4 is connected to the top of the first ball valve 3, a dredging mechanism 5 is movably connected to the right side of the feed pipe 4 through a sealing bearing, the dredging mechanism 5 includes an air pipe 6, and a second ball valve 7 is fixedly installed on the surface of the air pipe 6.

[0018] See also Figure 1 The surface of the air pipe 6 is movably connected to the feed pipe 4 through a sealed bearing, and the right end of the air pipe 6 is connected to a connecting pipe 8.

[0019] See also Figure 1 The left side of the throat pipe 1 is welded with a first flange 9, and the right side of the throat pipe 1 is welded with a second flange 10. By providing the first flange 9 and the second flange 10, it is convenient for the user to connect the throat pipe 1 with external pipelines and equipment.

[0020] See also Figure 1 The nozzle 2 is of conical design, and the first ball valve 3 is located at the top of the nozzle 2.

[0021] See also Figure 3 A knob 11 is fixedly provided on the surface of the air pipe 6. By providing the knob 11, it is convenient for the user to rotate the air pipe 6, thereby further increasing the purge range and preventing powder from adhering to the surface of the valve core, thereby affecting the material passing efficiency. The surface of the knob 11 is provided with anti-slip grooves.

[0022] When in use, the second flange 10 is connected to the water outlet end of the pump body. When mixing, the pumped liquid is transported to the inside of the throat 1. At this time, the high-speed flowing liquid forms a negative pressure through the throat 1, and the dry powder in the feed pipe 4 is sucked into the throat 1, so that the liquid and the dry powder are quickly mixed to improve efficiency and safety. The connecting pipe 8 is connected to the air outlet end of the air pump, and the external air pump works regularly, so that the high-pressure air of the air pump is transported to the inside of the air pipe 6 through the second ball valve 7. The air pipe 6 blows the high-pressure air to the inside of the first ball valve 3, thereby sweeping away some of the dry powder adhering to or accumulated on the valve core to avoid blockage of the first ball valve 3.

[0023] In summary: the jet pump device suitable for adding dry powder for liquid preparation solves the problem of uneven manual stirring and dust flying around during stirring, which easily endangers the health of workers, through the cooperation of the throat 1, the nozzle 2, the first ball valve 3, the feed pipe 4 and the dredging mechanism 5.
