[0025] Such asFigure 1 As shown in the figure, the present application provides a homogenizing device for cement raw meal, which includes a homogenizing silo body 1. An opening is provided at the top of the homogenizing silo body 1, and a matching cover plate 2 is provided at the opening. A feeding pipe 3 is fixedly provided in the middle of the cover plate 2. The feeding pipe 3 penetrates through the cover plate 2. The lower end of the feeding pipe 3 is rotatably connected to a distributing pipe 4. An inclined downward distributing branch pipe 5 is connected to the side of the distributing pipe 4. A blocking member 6 is provided in the distributing pipe 4. The blocking member 6 enables part of the cement raw meal to fall from the distributing branch pipe 5 when the cement raw meal falls from the distributing pipe 4. A driving assembly 7 is provided on the cover plate 2. The driving assembly 7 is used to drive the distributing pipe 4 to rotate. When the cement raw meal falls from the feeding pipe 3 into the distributing pipe 4, part of the cement raw meal falls from the lower end of the distributing pipe 4, and part of the cement raw meal falls from the distributing branch pipe 5 under the action of the blocking member 6. At the same time, the driving assembly 7 drives the distributing pipe 4 to rotate, driving the distributing branch pipe 5 to rotate, so that part of the cement raw meal falls into the periphery of the homogenizing silo body 1, avoiding the phenomenon of high in the middle and low around, maximizing the effective capacity of the homogenizing silo body 1, and ensuring the homogenizing effect of the homogenizing silo body 1 on the cement raw meal.

[0026] As Figure 1 shown in the figure, the driving assembly 7 includes a driving motor 71, a rotating shaft 72 and a gear 73. The driving motor 71 is fixedly provided on the top of the cover plate 2. The rotating shaft 72 is rotatably arranged in the homogenizing silo body 1. The upper end of the rotating shaft 72 penetrates through the cover plate 2 and is connected to the output shaft of the driving motor 71. The gear 73 is fixedly provided at the lower end of the rotating shaft 72. A toothed ring 41 is fixedly provided on the outer side of the upper end of the distributing pipe 4. The gear 73 meshes with the gear 73. Specifically, the driving motor 71 drives the rotating shaft 72 to rotate, the rotating shaft 72 drives the gear 73 to rotate, the gear 73 drives the toothed ring 41 to rotate, the toothed ring 41 drives the distributing pipe 4 to rotate, and the distributing pipe 4 drives the distributing branch pipe 5 to rotate.

[0027] As Figure 1 shown in the figure, there are two distributing branch pipes 5, and the two distributing branch pipes 5 are symmetrically arranged. Under the action of the blocking member 6, part of the cement raw meal falls from the lower end of the distributing pipe 4, and part of the cement raw meal falls from the two distributing branch pipes 5. When the distributing branch pipes 5 rotate, the cement raw meal falls on the periphery of the homogenizing silo body 1. The symmetrical arrangement of the two distributing branch pipes 5 can improve the speed of distributing materials to the periphery of the homogenizing silo body 1 per unit time.

[0028] As Figure 1 shown in the figure, a hoisting assembly 8 is provided at the bottom of the cover plate 2. The hoisting assembly 8 is used to strengthen the support for the distributing pipe 4, prevent the distributing pipe 4 from falling off during the rotation process, and extend the service life of the device.

[0029] As Figure 1 ​As shown, the hoisting assembly 8 includes a support plate 81 and at least two suspension rods 82. The support plate 81 is fixedly arranged at the bottom of the cover plate 2 through the suspension rods 82. The upper end of the cloth pipe 4 movably penetrates through the support plate 81. The upper end of the cloth pipe sleeve is sleeved on the lower end of the feed pipe 3. A limiting ring 42 is fixedly arranged on the outer side of the upper end of the cloth pipe 4. The limiting ring 42 is located at the top of the support plate 81 and abuts against the support plate 81. In this embodiment, the suspension rods 82 are designed to be two, and the two suspension rods 82 are symmetrically arranged. The support plate 81 is located between the limiting ring 42 and the tooth ring 41. The limiting ring 42 is located above the tooth ring 41. The limiting ring 42 prevents the cloth cylinder from slipping off the support plate 81.

[0030] As Figure 1 and Figure 2 shown, the stopper 6 is located at the connection between the cloth pipe 4 and the cloth branch pipe 5. The stopper 6 is in the shape of a frustum with a through middle part. When the raw cement material falls into the cloth pipe 4, a part of the raw cement material passes through the middle part of the stopper 6 and finally falls from the lower end of the cloth pipe 4, and a part flows around the stopper 6 to the two cloth branch pipes 5 and then falls from the cloth branch pipes 5.

[0031] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
