Description

Technical Field

[0001] The utility model relates to the technical field of powder homogenization devices, in particular to a fully stirring and mixing type all-solid waste gelling material convection homogenization device. Background Art

[0002] All-solid waste cementitious material is a hydraulic cementitious material prepared from industrial solid wastes such as slag and desulfurized gypsum. It is used to replace silicate cement in concrete pavement projects, reduce the accumulation of industrial solid waste, and solve environmental problems and resource waste. Compared with traditional cement, it has low hydration heat, micro expansion and strong resistance to sulfate erosion, and can effectively alleviate the effects of surface shrinkage and cracking caused by the temperature difference between day and night. It is suitable for mine filling, geotechnical engineering, ecological restoration and other fields. For this purpose, a convection homogenization device for all-solid waste cementitious material is proposed.

[0003] The patent announcement number is: CN220661303U, which discloses a convection homogenization device for all-solid waste gelling materials. The convection homogenization device for all-solid waste gelling materials is arranged, including a homogenization tank, a feeding device, a homogenization fan and a heating device. The feeding device is arranged on the top of the homogenization tank, and homogenization fans are arranged on the two opposite sides of the homogenization tank. The homogenization fans are connected to the heating device, and the heating device blows air into the homogenization tank through the air inlet pipe; the homogenization device is arranged on the two opposite sides of the homogenization tank, and the homogenization fans are connected to the heating device. Hot air is blown into both sides of the homogenization tank at the same time to form convection. The convective hot air better homogenizes the gelling material in the tank and takes away the moisture in the gelling material.

[0004] During the use of the existing all-solid waste cementitious material convection homogenization device, after the material enters the interior of the device, the convective hot air can melt the material, but the melting speed is slow, and the incompletely melted material accumulates inside the device, resulting in incomplete material homogenization, affecting subsequent processing, and the hot air transmission height is fixed and cannot be adjusted according to the height of the material accumulation, which needs to be improved. Therefore, the present application proposes a fully stirred and mixed all-solid waste cementitious material convection homogenization device. Utility Model Content

The homogenizing cylinder 1 pours out the homogenized material through the setting of the discharge door 11, and a door handle 12 is fixedly installed above the discharge door 11. The homogenizing cylinder is supported and erected by a tripod 14 at the bottom, and a mounting seat for rotating and mounting a rotating shaft 43 is provided at the bottom of the homogenizing cylinder, and a motor 15 for driving the rotating shaft to rotate is installed in the middle position inside the homogenizing cylinder 1.

[0026] Furthermore, the rotating fan 44 is located at the top of the rotating shaft 43, and the hybrid fan is located below the rotating fan. The hybrid fan is arranged in multiple groups from bottom to top, and the circumferential positions of the frame-shaped fan blades 4 of the hybrid fan from bottom to top are all staggered. The hybrid fan 4 is located inside the homogenizing drum 1 through the setting of the rotating shaft 43, and a motor 15 is arranged at the bottom of the rotating shaft 43. The motor 15 causes the rotating shaft 43 to rotate, thereby driving the rotation of the hybrid fan 4.

The homogenizing cylinder 1 is connected to the heating device 3 through the heat transfer pipe 32. The heating device 3 generates heat through the heat source machine 31 to continuously provide heat for the interior of the homogenizing cylinder 1. The heating device 3 is located on both sides of the homogenizing cylinder 1 to form heat convection to melt the all-solid waste gelling material. The all-solid waste gelling material will gradually heat up due to the high-temperature hot air. As more and more all-solid waste gelling material accumulates, the internal all-solid waste gelling material is not completely melted. The motor 15 can be turned on and the motor 15 can be used to drive the rotating shaft 43 to rotate. The hybrid fan 4 and the rotating fan 44 are respectively installed on the outside of the rotating shaft 43.

The rotation of the fan inner roller 41 and the fan rod 42 can stir the material inside the homogenizing cylinder 1. The stirred material is constantly changing and displaced, so that it contacts with the heat, so that the solid waste gelling material can be melted. As more and more solid waste gelling material is poured in, the heat transfer tube 32 can be rotated through the adjusting device 34 to rotate the heat transfer tube 32 at the end, change the end position of the heat transfer tube 32, and make the heat transfer from all parts of the homogenizing cylinder 1. At the same time, a rotating fan 38 is provided at the end of the heat transfer tube 32. The rotating fan 38 rotates through the heat inside the heat transfer tube 32, so that the heat can be easily dispersed when discharged. Finally, the homogenized material inside the homogenizing cylinder 1 can be discharged through the setting of the discharge door 11, and the entire use process of the whole solid waste gelling material convection homogenization device is completed in this way.
