Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a cement material homogenizing system. Background Art

[0002] Before cement enters the mill, multiple materials need to be mixed evenly and then enter the mill stably. Specifically, during production, multiple materials enter the silo. After being mixed evenly, the flow of materials is controlled by a gate or regulating device at the outlet at the bottom of the silo. The weighing sensor installed on the silo monitors the weight of the material in the silo in real time, thereby achieving accurate measurement of the material flow and stably feeding the mill.

[0003] During operation, various materials are transported to the homogenizing equipment by the skirt belt for homogenization, crushed by the roller press, and then classified by the scattering classifier before entering the cement mill for grinding. During the process of transporting various materials to the homogenizing equipment, there will be a phenomenon of aggregation and segregation due to the same substances, so that various materials cannot be evenly mixed together, resulting in uneven material structure. For this reason, we have proposed a cement material homogenization system to solve the above problem. Utility Model Content

[0004] The present application provides a cement material homogenizing system, which solves the problem of uneven mixing of cement materials and segregation caused by the easy aggregation of similar materials.

[0005] The present application provides a cement material equalizing system, including an equalizing bin, a plurality of feeding devices are installed on the equalizing bin, a distribution disc is installed in the equalizing bin, a dropping point of the feeding device corresponds to the distribution disc, a dropping hole is provided on the distribution disc, a distribution pipe corresponding to the dropping hole is installed below the distribution disc, a material throwing auger is installed in the distribution pipe, a driving device for driving the material throwing auger is installed below the distribution pipe, and a plurality of discharge ports are evenly spaced on a side wall around the distribution pipe.

[0006] Preferably, a dust hood is fixed to the top of the material balancing bin via a bracket, a dust suction pipe is installed on the top of the dust hood, and a plurality of installation notches corresponding to the feeding device are provided on the dust hood.

[0007] Preferably, a weighing silo is installed on the discharge pipe of the equalizing silo, and a control valve is installed at the feeding end of the discharge pipe located at the weighing silo.

[0008] Preferably, the material distribution tray is fixed on the material equalizing bin via a bracket.

[0009] Preferably, an anti-wear lining is installed in the equalizing bin.

[0010] Preferably, the feeding device is a conveyor belt, a bucket elevator or a bolt feeder.

[0011] Preferably, the diameter of the distribution disc is 1350 mm, and the diameter of the drop hole is 300 mm.

[0012] Preferably, the edge of the cloth tray is bent upward.

[0013] Preferably, the edge of the distribution tray has a curved surface with a height of 100 mm.

[0014] Preferably, the equalizing bin is in the shape of a round barrel or a polygonal barrel.

[0015] It can be seen from the above technical scheme that the present application provides a cement material equalizing system. During operation, a variety of raw materials are sent to the equalizing bin through a feeding device and fall onto a distribution disk. Part of the materials accumulate on the distribution disk and fall from the edge of the distribution disk, and part of the materials enter the distribution pipe through the drop hole and are thrown out from the discharge port by the rotating throwing auger. The two parts of the materials collide and gather again and fall into the equalizing bin, which can effectively break up the aggregated materials and improve the mixing quality, so that the materials are evenly mixed in the equalizing bin, which stably improves the quality of cement. The even materials further reduce the bearing wear and power of the mill.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. Through the setting of the distribution plate, the materials are diverted on the distribution plate, which can be used to mix the materials more evenly and improve the uniformity of material mixing;

[0018] 2. Through the setting of the drop hole and the throwing auger, the material is divided into two parts for separation. One part is diverted along the edge of the distribution plate, and the other part is thrown out by the throwing auger in the drop hole, and then collides and mixes again, which further improves the uniformity of material mixing and can also break up the aggregated materials.

[0019] In summary, the present application makes the material mixing more uniform through the multi-stream diversion method. The material thrown out by the material-throwing auger during the diversion process further improves the uniformity of the material mixing, and can also scatter larger similar aggregated materials, thereby improving the grinding efficiency of the mill and the cement quality.

[0026] In the utility model, since some materials have a large ash content, a large amount of dust will be generated when adding materials. Therefore, a dust hood 8 is fixed to the top of the equalizing bin 1 through a bracket. The dust hood 8 covers the top of the entire equalizing bin 1 to prevent dust from overflowing. A dust suction pipe 7 is installed on the top of the dust hood 8.

Therefore, in order to increase the service life of the material equalizing bin 1, an anti-wear lining 2 is installed at the position where the material equalizing bin 1 contacts the thrown out material to increase the service life of the material equalizing bin 1.
