Description

Technical Field

[0001] This utility model relates to the technical field of grinding aid processing equipment, and in particular to a metering and feeding device for a cement grinding aid reactor. Background Technology

[0002] Cement grinding aids are chemical additives that improve the grinding effect and performance of cement. They can significantly increase cement hourly output, cement strength at various ages, and improve its fluidity. Cement grinding aids can substantially reduce the electrostatic adsorption and balling phenomenon formed during grinding and reduce the tendency for ultrafine particles to re-agglomerate. Cement grinding aids can also significantly improve cement fluidity, enhance the grinding effect of the mill and the classification efficiency of the air classifier, thereby reducing grinding energy consumption. Cement produced using grinding aids has a lower tendency for compaction and agglomeration, which facilitates cement loading and unloading and reduces cement silo wall adhesion. The production and processing of cement grinding aids requires the use of a reaction vessel.

[0003] The existing Chinese patent with publication number CN208599747U discloses a cement grinding aid reactor. The existing technical solution described above has the following defects: Although the above technical solution uses a magnetic ring to fix the T-shaped rod inside the annular groove, thereby achieving the purpose of sealing the connecting pipe with a conical plug to prevent material leakage, and uses a rotating gear to drive the annular ring to rotate, thereby driving the cleaning blade to rotate and clean the inside of the reactor shell, the above technical solution cannot automatically feed the cement grinding aid. It still requires manual addition of materials to the reactor for production and processing, which is cumbersome and greatly reduces its practicality. Utility Model Content

[0031] In one embodiment, a guide plate 23 is provided at the middle position of the top surface of the partition 27, and the guide plate 23 has a triangular structure. By using the guide plate 23 at the middle position of the top surface of the partition 27, the material entering the regulating box 3 can be guided to prevent the material from remaining on the partition 27, thereby facilitating the crushing and dispersing of the material.

[0032] In one embodiment, inclined plates 22 are provided on both sides of the bottom upper surface of the feed box 2, and the inclined plates 22 are matched with the feed box 2.

[0035] In one embodiment, the connecting block 10 and the connecting groove 9 are rectangular structures, and the connecting block 10 and the connecting groove 9 are slidably connected. The use of the connecting block 10 and the connecting groove 9 can limit the adjustment box 3, thereby facilitating the maintenance of the stability of the adjustment box 3 during movement.

[0036] In one embodiment, the connecting plate 18 is movably connected to the feed box 2, and the baffle 13 is movably connected to the feed pipe 12. The feed box 2 can be opened or closed by using the connecting plate 18, and the feed pipe 12 can be opened or closed by using the baffle 13.

[0037] In one embodiment, the control circuit of the control panel can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0038] Working principle:

[0039] In use, materials are added to the regulating box 3, and the materials fall onto the connecting plate 18 in the feeding box 2. The weighing scale 17 on the connecting plate 18 weighs the materials entering the feeding box 2. After weighing, the electric push rod 20 on one side of the feeding box 2 is opened. The electric push rod 20 moves the push plate 19, which in turn moves the connecting plate 18 and the baffle 13 via the connecting rod 21, thus opening and closing the feeding box 2 and the feeding pipe 12. This automatically adds the materials into the vessel 1, eliminating the need for manual addition and simplifying the process. The weighing scale 17 on the top surface of the connecting plate 18 allows for precise feeding, improving its practicality. The first motor 7 on one side of the top surface of the side plate 8 drives the gear 6 to rotate, which in turn moves the rack 5. While the rack 5 moves, it also moves the regulating box 3, thereby adjusting the positional distance between the regulating box 3 and the feed box 2. This allows for adjustment of the space between the regulating box 3 and the feed box 2, enabling the feed rate to be freely changed according to actual usage needs. This reduces limitations during use and further improves the practicality of the device. By opening the dual-axis motor 28 located in the middle of the bottom surface of the partition 27, the dual-axis motor 28 drives the rotating rod 26 to rotate. Simultaneously, the rotating rod 26 drives the dispersing blade 25 on the rotating rod 26 to rotate. The dispersing blade 25 can crush and disperse clumped materials, preventing clumped materials from entering the reactor 1 and causing uneven mixing. This facilitates the processing of the fed materials. The guide plate 23 located in the middle of the top surface of the partition 27 guides the materials entering the regulating box 3, preventing material residue on the partition 27, thus facilitating the crushing and dispersing of the materials.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
