The two mixing mechanisms are positioned opposite each other on both sides of the mixing cylinder. Each mixing mechanism includes a mixing shaft rotatably mounted on the mixing cylinder and multiple mixing blades circumferentially distributed on the outer surface of the mixing shaft. The two drive mechanisms are positioned opposite each other on both sides of the mixing cylinder and are respectively connected to the two mixing shafts to drive the opposing mixing shafts to rotate. The two drive mechanisms independently control the rotational speed, direction, and timing sequence of the two mixing shafts to achieve optimal mixing efficiency. The distance between the mixing blades and the inner wall of the mixing cylinder can be adjusted, and different types of mixing blades can be replaced to adapt to different needs, achieving functions such as mixing, stirring, and granulation to meet the different requirements of mixing different materials.

[0003] This equipment uses two opposing mixing mechanisms to mix materials, but the mixing effect is not ideal and the mixing efficiency is low. Therefore, it is necessary to design a dual-drive mixer to improve the mixing efficiency and mixing quality. Utility Model Content

Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-2 The present invention provides a technical solution: a dual-drive mixer, including a cylinder 1, a support frame 2 fixedly connected to the lower side of the cylinder 1, and a cover 3 provided on the side of the cylinder 1 away from the support frame 2 along the axial direction.

[0021] The cylinder 1 has a cavity 4 inside. The cavity 4 is a cylindrical cavity and opens to the side away from the support frame 2. The cover 3 is detachably and fixedly connected to the cylinder 1 to seal the cavity 4.

[0022] A stirring shaft 5 is vertically arranged in the center of the cavity 4. A detachable stirring blade 6 is fixedly connected to the outer circumference of the stirring shaft 5. The stirring blade 6 does not directly contact the inner wall of the cavity 4 when it rotates. The stirring blade 6 can be selected from, but is not limited to, ribbon stirring blade, screw stirring blade, flat blade paddle stirring blade, folding blade stirring blade, etc. In this embodiment, a ribbon stirring blade is selected.

[0023] The end of the stirring shaft 5 closest to the support frame 2 along the axial direction is rotatably connected to the inner wall of the cavity 4. The end of the stirring shaft 5 away from the support frame 2 along the axial direction passes through the cover 3 and is movably connected to the cover 3. A drive motor 7 is provided on the side of the stirring shaft 5 that passes through the cover 3 along the axial direction.

[0024] A fixing frame 8 is fixedly connected to the side of the cover 3 away from the cylinder 1. The fixing frame 8 is in the shape of an inverted "U". The drive motor 7 is set vertically. The fixed end of the drive motor 7 is fixedly connected to the fixing frame 8. The output shaft of the drive motor 7 faces the side of the cover 3. The output shaft of the drive motor 7 is coaxially fixedly connected to the stirring shaft 5. The drive motor 7 drives the stirring shaft 5 to rotate, which in turn drives the stirring blade 6 to rotate, thus stirring the raw materials in the cavity 4.

[0025] Inside cavity 4, three stirring shafts 2 9 are vertically arranged, and the three stirring shafts 2 9 are evenly distributed in a circle with the axis of stirring shaft 1 5 as the center.

[0026] The outer circumference of the stirring shaft 29 is fixedly connected with detachable stirring blades 210. When stirring blades 210 rotate, they do not directly contact the inner wall of the cavity 4, and do not interfere with the rotation of stirring blade 16.

[0027] The stirring blade 10 can be selected from, but is not limited to, ribbon stirring blade, screw stirring blade, flat blade paddle stirring blade, folding blade stirring blade, etc. In this embodiment, a flat blade paddle stirring blade is selected.

[0028] The end of the stirring shaft 2 9 that is close to the support frame 2 along the axial direction is rotatably connected to the inner wall of the cavity 4, and the end of the stirring shaft 2 9 that is away from the support frame 2 along the axial direction passes through the cover 3 and is movably connected to the cover 3.

[0029] A gear 11 is fixedly connected to one end of the stirring shaft 2 9 that passes through the cover body 3, and the gear 11 is rotatably connected to the cover body 3.

[0030] Gear 2 12 is rotatably connected to the cover 3. Gear 2 12 is coaxially arranged with stirring shaft 1 5. Stirring shaft 1 5 passes through gear 2 12 and is movably connected to gear 2 12.

[0031] A second drive motor 17 is fixedly connected to the fixed frame 8. The second drive motor 17 is vertically set, and the output end of the second drive motor 17 faces the cover body 3. A third gear 13 is fixedly connected to the output end of the second drive motor 17. The third gear 13 meshes with the second gear 12, and the second gear 12 meshes with the first gear 11. Thus, the second drive motor 17 drives the three stirring shafts 9 to rotate through gear transmission, and then the stirring blades 10 stir the raw materials in the cavity 4.

[0032] The cover 3 is provided with a liquid inlet 14 and a feed inlet 15. Both the liquid inlet 14 and the feed inlet 15 are connected to the cavity 4. Neither the feed inlet 15 nor the liquid inlet 14 interferes with the transmission mechanism associated with the drive motor 1 7 and the drive motor 2 17.

[0033] The liquid inlet 14 is used to introduce the liquid involved in the stirring into the cavity 4, and the feed inlet 15 is used to introduce the raw materials involved in the stirring into the cavity 4.

[0034] A discharge port 16 is provided on the side of the cavity 4 near the support frame 2. An electric control valve is provided on the discharge port 16. The discharge port 16 is used to release the stirred raw material out of the cylinder 1. The electric control valve is used to control the opening and closing of the discharge port 16.

[0035] In this embodiment, the liquid and raw materials to be stirred are introduced into the cavity 4 through the liquid inlet 14 and the feed inlet 15, respectively. At this time, the electric control valve is in the closed state, and the liquid and raw materials cannot be released from the discharge outlet 16.

[0036] Simultaneously start drive motor 7 and drive motor 17. Drive motor 7 drives the stirring blade 6 to rotate through stirring shaft 5, and drive motor 17 drives the stirring blade 10 to rotate through stirring shaft 9.

[0037] The rotation direction of the second stirring blade 10 is opposite to that of the first stirring blade 6, forming a three-dimensional shear flow field, thereby improving the stirring effect on the raw materials.

[0038] By setting dual independent drives for drive motor 7 and drive motor 17, the speeds of stirring shaft 5 and stirring shaft 9 can be adjusted independently, thereby enabling effective adjustment according to the ratio of raw materials being stirred.
