TECHNICAL FIELD

[0001] The utility model relates to the technical field of feeding rack, concretely to a cement mill head warehouse feeding rack with same material anti -accumulation structure. BACKGROUND

[0002] The cement mill head warehouse feeding rack is an important equipment component in the cement production process, mainly used for controlling and guiding the material into the mill head warehouse of the cement mill. The cement mill is usually one of the key equipment in the cement plant for grinding clinker, gypsum and other mixed materials into cement. In the mill head warehouse of the cement mill, the material enters through the feeding rack, thereby ensuring that the material can enter the mill interior uniformly and stably for further grinding, providing stable material supply for the subsequent grinding process.

[0003] The cement mill head warehouse feeding rack can ensure the stability of the material entering the cement mill by adjusting the material flow, avoiding excessive or insufficient material inflow. The feeding rack uniformly distributes the same material from the pre-homogenization warehouse to the entire grinding disc of the mill head warehouse. However, some materials in the cement raw material, such as clay, contain a certain amount of moisture, which causes the surface of the raw material particles to adhere to moisture, resulting in adhesion between particles, thereby forming larger lumps, which easily leads to the formation of lumps of raw materials. Therefore, we propose a cement mill head warehouse feeding rack with same material anti-accumulation structure. SUMMARY

[0004] The utility model aims at providing a cement mill head warehouse feeding rack with same material anti-accumulation structure to solve the problem of moisture in some materials in the cement raw material, which easily leads to adhesion between particles, thereby forming larger lumps, leading to the formation of lumps of raw materials.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4This utility model provides a technical solution: a cement mill head hopper feed rack with a structure to prevent the accumulation of the same raw material, including a hopper 1 and a metering valve 101. The metering valve 101 is installed on the lower side of the hopper 1 and is connected to the frame 102. A mixing hood 103 is fixed on the lower side of the frame 102, and a feeding belt assembly 104 is installed on the lower side of the mixing hood 103. The feeding belt assembly 104 includes a drive wheel, a drive belt, and a drive motor. A drive motor 2 is installed on one side of the mixing hood 103, and a synchronization component 1 201 and a synchronization component 2 202 are provided at the output end of the drive motor 2. The synchronization component 1 201 and the synchronization component 2 202 each include two synchronization pulleys and a synchronization belt. The synchronization pulleys on one side of the synchronization component 1 201... The synchronous pulley on one side of the synchronization component 202 is simultaneously connected to the output end of the drive motor 2. The synchronous pulleys of the synchronization component 1 201 and the synchronization component 202 are movably connected to the frame 102 and the mixing hood 103 respectively through bearings. The synchronous pulley of the synchronization component 1 201 away from the drive motor 2 is fixed to the bevel gear 1 203 through a shaft. The bevel gear 1 203 is connected to the bevel gear 2 204. The lower side of the bevel gear 2 204 is fixed to the upper side of the pinion 1 205 through a shaft. The pinion 1 205 is connected to the gear ring 1 206. The stirring frame 1 207 is fixed to the inner side of the gear ring 1 206. The lower side of the pinion 1 205 is fixed to the pinion 2 208 through a shaft. The pinion 2 208 is connected to the pinion 3 209. The pinion 209 is engaged with the gear ring 210. A mixing frame 211 is fixed to the inner side of the gear ring 210. Bevel gear 1 203, bevel gear 204, pinion 1 205, gear ring 1 206, pinion 2 208, pinion 3 209, and gear ring 210 are movably connected to the mixing hood 103 via bearings. Synchronizing pulleys on both sides of the synchronizing assembly 202 are fixed to the transmission gear 1 212 and the large gear 1 2121, respectively. The transmission gear 1 212 is engaged with the transmission gear 2 2122, and one side of the transmission gear 2 2122 is fixed to the large gear 2 2123. Mixing belt assemblies 213 are respectively provided between the two large gears 1 2121 and between the two large gears 2 2123. The mixing belt assembly 213 includes a transmission pulley. The transmission belts and the two mixing belt assemblies 213 have their transmission pulleys fixed to large gear 1 2121 and large gear 2 2123 respectively. The lower sides of large gear 1 2121 and large gear 2 2123 are respectively connected to driven gears 214. A cleaning brush 215 is fixed between the two driven gears 214. Transmission gear 1 212, large gear 1 2121, transmission gear 2 2122, large gear 2 2123 and driven gear 214 are movably connected to the frame 102 through bearings. The synchronous belt and synchronous pulley of synchronous assembly 1 201 are meshed. The synchronous belt and synchronous pulley of synchronous assembly 2 202 are meshed. Bevel gear 1 203 and bevel gear 2 204 are meshed. Small gear 1 205 and gear ring 1 206 are meshed.Small gear 208 meshes with small gear 3 209; small gear 3 209 meshes with gear ring 2 210; transmission gear 1 212 meshes with transmission gear 2 2122; large gear 1 2121 and large gear 2 2123 mesh with driven gear 214 respectively; and cleaning brush 215 is pressed against the transmission belt of mixing belt assembly 213.

[0024] In specific implementation, according to Figures 1-4When the cement mill head hopper feed rack conveys raw materials, the metering valve 101 is activated, causing the raw materials to fall onto the upper side of the mixing belt assembly 213. At this time, the drive motor 2 is activated, causing the output end of the drive motor 2 to simultaneously drive the synchronous pulleys of the first synchronous assembly 201 and the second synchronous assembly 202 to rotate. When the synchronous pulley of the second synchronous assembly 202 rotates, the synchronous belt and the synchronous pulley of the second synchronous assembly 202 mesh with each other, allowing the drive motor 2 to simultaneously drive the first transmission gear 212 and the large gear 2121 to rotate. Then, the first transmission gear 212 meshes with the second transmission gear 2122, causing the first transmission gear 2122 to drive the second transmission gear 2122 to rotate. The transmission gear 2122 drives the large gear 2123 to rotate, causing the large gear 1 2121 and the large gear 2123 to rotate simultaneously. At this time, the rotation direction of the large gear 1 2121 is opposite to that of the large gear 2123, causing the raw material conveying directions of the two mixing belt assemblies 213 to be opposite, thus causing the raw material to fall into the mixing hood 103. Simultaneously, the large gear 1 2121 and the large gear 2123 are respectively engaged with the driven gear 214, allowing the driven gear 214 to drive the cleaning brush 215 to rotate through the rotation of the large gear 1 2121 and the large gear 2123. The cleaning brush 215 then presses against the transmission belt of the mixing belt assembly 213, causing the cleaning brush 215 to remove the mixed material. The raw material attached to the belt of the belt assembly 213 is swept down and falls into the interior of the mixing hood 103. At this time, the output end of the drive motor 2 drives the synchronous pulley of the synchronization assembly 201 to rotate. Through the meshing connection between the synchronous belt and the synchronous pulley of the synchronization assembly 201, the drive motor 2 can drive the bevel gear 203 to rotate. The bevel gear 203 meshes with the bevel gear 204, allowing the bevel gear 204 to rotate along with the bevel gear 203. At this time, the bevel gear 204 can simultaneously drive the pinion 205 and the pinion 208 to rotate. When the pinion 205 rotates, it meshes with the gear ring 206, allowing the gear ring 206 to rotate. The mixing frame 207 rotates, and when the pinion 208 rotates, it meshes with the pinion 3 209, which in turn meshes with the gear ring 210. This allows the gear ring 210 to drive the mixing frame 211 to rotate. At this time, the rotation direction of the mixing frame 207 is opposite to that of the mixing frame 211. When the raw material entering the mixing hood 103 contains lumps, the mixing frame 207 and the mixing frame 211 can beat the lumps, breaking them into smaller particles. This allows the raw material to pass smoothly through the feed inlet into the grinding head chamber, ensuring that the raw material is more evenly distributed on the grinding disc after entering the mill, thereby improving grinding efficiency and the consistency of cement products.

[0025] In summary, when the cement mill head hopper feed rack conveys raw materials, the metering valve 101 is activated, causing the raw materials to fall onto the upper side of the mixing belt assembly 213 transmission belt. At this time, the drive motor 2 is activated, causing the two mixing belt assemblies 213 to convey raw materials in opposite directions, thus allowing the raw materials to fall into the mixing hood 103. The cleaning brush 215 can sweep the raw materials attached to the mixing belt assembly 213 transmission belt and let them fall into the mixing hood 103. At the same time, the mixing rack 1 207 and the mixing rack 211 can beat the lumps of raw materials, breaking them down into smaller particles, so that the raw materials can smoothly enter the mill head hopper through the feed inlet. This allows the raw materials to be more evenly distributed on the grinding disc after entering the mill, thereby improving grinding efficiency and the consistency of cement products.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
