Segregation-prevention vertical sand silo

Abstract

The invention relates to a sand silo, in particular to a segregation-prevention vertical sand silo. The segregation-prevention vertical sand silo comprises a silo body. The silo body mainly comprisesa cylindrical barrel body on the upper portion and a conical barrel body on the lower portion. A sand discharge port is formed in the lower end of the conical barrel body. A sand discharge valve is arranged on the lower portion of the sand discharge port. A feed chute is fixed to the center position of an upper cover plate of the silo body. An outlet of the feed chute is connected with a feed hopper in a butt joint manner. The feed hopper is fixed to the inner surface of the upper cover plate of the silo body. Drainage plates are fixed to the inner side wall of the silo body. A hole is formedin the center position of each drainage plate. A stirring device is arranged at the lower end of each hole. Each stirring device is connected to a rotating shaft in a rotating manner. The rotating shafts are fixed in grooves in the inner side wall of the silo body. The segregation-prevention vertical sand silo is provided with the drainage plates and the stirring devices, stirring paddles are driven to rotate under the effect of gravity of dry sand materials so that the stirring effect can be achieved, and the dry sand materials in the silo body can be evenly distributed without adding other power devices. The segregation-prevention vertical sand silo is simple in structure, good in segregation prevention effect, convenient to use and high in reliability.

Description

technical field [0001] The invention relates to a sand bin, in particular to a vertical sand bin for preventing segregation. Background technique [0002] Dry-mixed mortar is a mixture of bulk powder and granular materials. At present, the storage bins for storing dry sand mainly use vertical sand bins. The vertical sand bin adopts a vertical drop structure, and the dry sand after drying falls directly into the bin. Due to the high height, the large vertical drop in the bin, and the different specific gravity of dry sand materials with different particle sizes (0-5mm), free The rate of falling is different. During the storage and accumulation process, the dry sand naturally forms a cone shape, and the dry sand with a finer particle size naturally accumulates upward with the cone, while the dry sand with a relatively coarse particle size naturally flows from around the cone. When sliding down, it is very easy to produce secondary separation, that is, it will lead to the phen...

The vertical sand bin adopts a vertical drop structure, and the dry sand after drying falls directly into the bin. Due to the high height, the large vertical drop in the bin, and the different specific gravity of dry sand materials with different particle sizes (0-5mm), free The rate of falling is different. During the storage and accumulation process, the dry sand naturally forms a cone shape, and the dry sand with a finer particle size naturally accumulates upward with the cone, while the dry sand with a relatively coarse particle size naturally flows from around the cone. When sliding down, it is very easy to produce secondary separation, which leads to the "segregation" phenomenon of dry sand, so that the coarse and fine dry sand materials flow out from the sand bin during the discharge process, affecting the quality of dry-mixed mortar
