Technical Field

The utility model relates to the technical field of powder classifiers, in particular to a powder classifier with a multi-stage crushing structure.

Background Art

Powder classifiers are widely used in coal mills, raw material intermediate unloading drying mills and cement mill systems in new dry process cement production lines. They can be divided into three categories: three-separation powder classifiers, centrifugal powder classifiers and cyclone powder classifiers.

However, during the use of the existing powder classifier, the materials in the powder classifier are broken up only by the effect of wind blowing. Due to the presence of some large pieces of material, due to their heavy weight, the wind force acts on the material for a short time, which makes it impossible to completely break up the material. As a result, there will still be agglomerated materials when the materials are discharged, thereby reducing the powder selection quality of the materials.

Please refer to Figures 1-4. The utility model provides a technical solution: a powder classifier with a multi-stage crushing structure, including a powder classifier 5, a motor 1 is fixedly connected to the top of the powder classifier 5, and the output end of the motor 1 is rotatably connected to the inside of the powder classifier 5 to provide a power source for the operation of the device; a feed pipe 2 and a second air outlet pipe 6 connected to the inside of the powder classifier 5 are fixedly connected to the top of the powder classifier 5, which are used for injecting and discharging materials into the powder classifier 5 respectively; an air injection pipe 3 connected to the inside of the powder classifier 5 is fixedly connected to the surface of the powder classifier 5 for injecting air into the powder classifier 5; a first discharge pipe 4 connected to the inside of the powder classifier 5 is fixedly connected to the lower end of the powder classifier 5, which also discharges the material in the powder classifier 5.

The powder classifier 5 is provided with a crushing mechanism inside, which includes a rotating sleeve 7, the surface of which is fixedly connected to the output end of the motor 1, a shuttle-shaped grinding block 12 is fixedly connected to the lower end of the rotating sleeve 7, a grinding ring 10 is fixedly connected to the inner wall of the powder classifier 5, and the surface of the grinding block 12 contacts the inner wall of the grinding ring 10. Therefore, through the arrangement of the grinding ring 10 and the grinding block 12, the agglomerated materials in the powder classifier 5 can be ground and crushed by means of the friction force when the grinding ring 10 and the grinding block 12 rotate relative to each other, thereby ensuring the removal quality of the materials. The air outlet of the air injection pipe 3 corresponds to the conical surface of the upper end of the grinding block 12, so that the wind can blow on the inclined surface of the grinding block 12, and can guide the wind by means of the conical surface of the grinding block 12, thereby reducing the ventilation volume of the lower part of the powder classifier 5 and increasing the ventilation area of the upper part of the powder classifier 5, so that the agglomerated materials in the powder classifier 5 can be fully dispersed, thereby reducing the difficulty of powder selection, thereby improving the powder selection efficiency and improving the use effect of the device.

The upper surface of the grinding block 12 is fixedly connected with a conical crushing tip 13, so that through the setting of the crushing tip 13, the material falling on the grinding block 12 can be punctured and scattered, thereby reducing the difficulty of subsequent material processing and improving the efficiency of material processing. The interior of the rotating sleeve 7 is rotatably connected with a breaking rod 9, so that through the setting of the breaking rod 9, the material entering the powder classifier 5 can be preliminarily broken up, thereby reducing the subsequent material processing efficiency. The surface of the breaking rod 9 is fixedly connected with a conical breaking protrusion 8, the inner wall of the powder classifier 5 is fixedly connected with a fixing frame 11, and the surface of the fixing frame 11 is fixedly connected with a fixing rod 14.

The rotation of the rotating sleeve 7 and the grinding block 12 drives the position of the scattering rod 9 and the second bevel gear 16 to change. Since the position of the fixed rod 14 is fixed, the second bevel gear 16 and the first bevel gear 15 rotate relative to each other, and then through the meshing connection, the second bevel gear 16 is driven to rotate while revolving, and then the scattering rod 9 is driven to rotate, thereby driving the scattering protrusion 8 to rotate in the powder classifier 5, thereby scattering the material in the powder classifier 5 for many times. Through the setting of the crushing mechanism, the device can scatter and crush the material in the powder classifier 5 for many times during operation, so that the material can be fully crushed, thereby reducing the possibility of large particles in the material after the powder selection operation, thereby improving the material crushing efficiency and the quality of the powder selection operation, and has a high use and promotion value.

Working principle: When using the device, the staff starts the motor 1, which drives the rotating sleeve 7 and the grinding block 12 to rotate, and then drives the breaking rod 9 to break up the materials in the powder classifier 5. The rotation of the rotating sleeve 7 and the grinding block 12 drives the breaking rod 9 and the second bevel gear 16 to change their positions. Since the position of the fixed rod 14 is fixed, the second bevel gear 16 and the first bevel gear 15 rotate relative to each other, and then the second bevel gear 16 is driven by the meshing connection to rotate while revolving, and then the breaking rod 9 is driven to rotate, thereby driving the breaking protrusion 8 to rotate in the powder classifier 5, so that the materials in the powder classifier 5 are broken up multiple times.
