[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0016] like Figure 1 、 Figure 2 As shown, a highly efficient mixing device for oleum and washing acid comprises a mixing acid tank 1 filled with washing acid, wherein the bottom side end of the mixing acid tank 1 is fixedly connected to a premixing assembly via a connecting conduit, and a circulation pump 2 is fixed on the connecting conduit, and the top of the premixing assembly is fixedly connected to an oleum input pipe, and the bottom is fixedly connected to the top of the mixing acid tank 1 via a conduit. The premixing assembly can increase the mixing contact area of oleum and washing acid.
[0017] Specifically, oleum is introduced into the premixing assembly through the oleum inlet pipe, and the washing acid is pumped into the premixing assembly by the circulation pump 2. In the premixing assembly, the mixing contact area of the two acids is increased, thereby improving the mixing efficiency;
[0018] After mixing, it enters the mixed acid tank 1 to continue mixing, and is pumped out by the circulation pump 2 and re-introduced into the pre-mixing component, and then mixed with fuming sulfuric acid to form a circulating system, thereby achieving the adsorption of washing acid moisture.
[0019] The premixing assembly includes a mixing tube 3 , in which baffles 4 are arranged from top to bottom, and the side ends of the baffles 4 are movably connected to the inner wall of the mixing tube 3 .
[0020] Specifically, the mixing between fluids is promoted by the baffles 4 in the mixing tube 3. A plurality of baffles 4 are provided in the mixing tube 3. The baffles 4 are arranged in sequence from top to bottom, and their side ends are movably connected to the inner wall of the mixing tube 3. When the fluid passes through the mixing tube 3, the baffles 4 force the fluid to change direction, thereby increasing the contact area and turbulence between the fluids. This repeated change of direction and turbulence contributes to the full mixing of different fluids and improves the mixing efficiency. The movable connection design of the baffles 4 moves slightly under the action of fluid pressure, further promoting the mixing effect.
[0021] The side end of the baffle plate 4 passes through the inner wall of the mixing tube 3 and is fixedly connected to the driving component, and the driving component can drive the baffle plate 4 to rotate.
[0022] The driving assembly includes an outer sleeve 5, which is fixedly sleeved on the outside of the mixing tube 3, and a cavity is formed between the inner wall of the outer sleeve 5 and the outer wall of the mixing tube 3. A driving member is provided in the cavity, and the driving member is fixedly connected to the corresponding side end of the baffle 4 through a rotating shaft, and the rotating shaft is inserted into the inner wall of the mixing tube 3 and is rotatably connected in the mixing tube 3.
[0023] The driving component includes a fan 6, which is fixed on the rotating shaft and arranged in the cavity. A blowing duct 7 is correspondingly provided at the side end of the fan 6. The blowing duct 7 is fixed on the outer sleeve 5 and passes through the outer sleeve 5 to be fixedly connected to the hair dryer 8. An air outlet duct is fixed at the bottom of the outer sleeve 5.
[0024] Specifically, the blower 8 delivers air to the blowing duct 7, and the air enters the cavity through the blowing duct 7, causing the fan 6 to rotate, driving the baffle 4 to rotate, and the rotation of the baffle 4 can promote uniform mixing of the materials in the mixing tube 3.
[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
