The air intake pipe 11 is sealed and rotatably connected to the mixing outer shell 3 and the circular top plate 16.

[0034] The top opening of the air inlet pipe 11 is connected to an external air source via a rotary joint 6, and a leakage hole is provided at the bottom opening of the air inlet pipe 11.

[0035] Several air outlet units are fixed and connected radially on the air intake pipe 11, and the air outlet units are evenly distributed along the circumference of the air intake pipe 11. Each air outlet unit includes multiple air outlet pipes 22, and the multiple air outlet pipes 22 located in the same air outlet unit are evenly distributed at equal intervals along the axial direction of the air intake pipe 11.

[0036] Several rotating shafts 10 are vertically arranged inside the mixing inner shell 8, and these shafts 10 are evenly distributed along the circumference of the air inlet pipe 11. Each rotating shaft 10 corresponds to one of several air outlet units. Each rotating shaft 10 extends upward through the mixing inner shell 8 and is rotatably and sealingly connected to it. Multiple breaking units for breaking up air bubbles are fixedly installed on each rotating shaft 10, and each of the multiple breaking units on each rotating shaft 10 corresponds to one of the multiple air outlet pipes 22 of the corresponding air outlet unit.

[0037] Each crushing unit is located at the port of the corresponding air outlet 22 away from the air inlet 11. Specifically, the crushing unit includes a fixed ring fixedly sleeved on the rotating shaft 10, and multiple crushing rods 12 are fixedly arranged radially on the fixed ring, with the multiple crushing rods 12 evenly distributed along the circumference of the fixed ring.

[0038] Multiple crushing plates 9 are fixedly installed on the inner wall of the mixing inner shell 8, and the multiple crushing plates 9 are evenly distributed on the inner wall of the mixing inner shell 8.

[0039] A power mechanism is installed inside the mixing shell 3. The power mechanism is connected to the mixing inner shell 8 and the air intake pipe 11 to drive the mixing inner shell 8 and the air intake pipe 11 to rotate.

[0040] Specifically, the power mechanism includes a motor 7, which is fixedly mounted on the top inner wall of the mixing housing 3 and located inside the connecting ring 15. A first gear 17 and a first internal gear ring 19 are fitted onto the intake pipe 11.

[0041] A linkage component is installed inside the hybrid outer shell 3. Multiple rotating shafts 10 are driven to rotate by the hybrid inner shell 8 through the linkage component.

[0042] Specifically, the linkage assembly includes a second internal gear ring 21 and multiple third gears 20.

[0043] In this embodiment, the multiple crushing plates 9 are divided into several groups, and the multiple crushing plates 9 in the same group are evenly distributed along the vertical direction. A gap is formed between two adjacent crushing plates 9 in the same group to allow the crushing rod 12 to rotate.

[0044] Working principle: When preparing trichlorotrifluoroethane using this portable mixing and feeding device, the reaction liquid is added to the mixing inner shell 8 through the liquid inlet pipe 5, and the reaction gas is added to the mixing inner shell 8 through the gas inlet pipe 11. The order of addition is to first introduce the reaction gas and then the reaction liquid.

[0045] At the same time, motor 7 is started. The output shaft of motor 7 drives the second gear 18 to rotate, and the second gear 18 drives the first gear 17 and the first internal gear ring 19 to rotate. The first gear 17 drives the intake pipe 11 to rotate, and the first internal gear ring 19 drives the connecting ring 15 to rotate.

[0046] When the inlet pipe 11 rotates, it drives the outlet pipe 22 to revolve around the central axis of the mixing inner shell 8, and the outlet pipe 22 stirs the reaction liquid.

[0047] When the connecting ring 15 rotates, it drives the mixing inner shell 8 to rotate. The mixing inner shell 8 drives the crushing plate 9 to revolve around the air inlet pipe 11, thereby breaking up the bubbles in the reaction liquid.

[0048] When the mixing inner shell 8 rotates, it drives the rotating shaft 10 to revolve around the air intake pipe 11. The rotating shaft 10 drives the third gear 20 to revolve around the air intake pipe 11. At this time, since the third gear 20 meshes with the second internal gear ring 21, the second internal gear ring 21 pushes the third gear 20 to rotate, and the third gear 20 drives the rotating shaft 10 to rotate. The rotating shaft 10 drives the fixed ring to rotate, and the fixed ring drives the crushing rod 12 to break up the bubbles formed at the opening of the air outlet pipe 22 away from the air intake pipe 11.

[0049] Once the amount of reaction liquid inside the inner shell 8 is sufficient, stop adding the reaction liquid. Then, continue to introduce the reaction gas, and stop adding the reaction gas once the amount of reaction gas is sufficient.

[0050] After mixing is complete, turn off motor 7 and open control valve 13, and the product is discharged through liquid outlet pipe 4.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
