Anti-separation dry sand silo and method

Abstract

The invention discloses an anti-separation dry sand silo and method. The anti-separation dry sand silo comprises a stock silo and an anti-separation device. The anti-separation dry sand silo is characterized in that the stock silo comprises a feed articulated chute, a feed hopper, a silo body and a discharge valve, the feed articulated chute is fixed on the upper cover plate of the silo body, the silo body mainly comprises an upper cylinder body and a lower cone cylinder body, and the discharge valve is mounted on a discharge pipe at the lower end of the silo body. The anti-separation device comprises a main pipe and a plurality of side pipes, the main pipe is fixed inside the silo body through an upper support and a lower support, the upper end of the main pipe is made to be in butt joint with the feed hopper, and the lower end of the main pipe is hung in the air. The anti-separation dry sand silo and method have the advantages that separation is effectively prevented from being generated on dry sand in the process that the dry sand flows into the silo, the integrated falling down of sand materials in the discharge process of the dry sand silo is achieved, the falling down process is clean and smooth, production cost is saved, and quality of finished mortar products is guaranteed. The anti-separation dry sand silo is simple in structure, good in anti-separation effect, high in operational reliability, and capable of effectively improving quality of finished mortar products, and has wide practicability.

Description

technical field [0001] The invention relates to a dry sand bin, which belongs to the technical field of preventing segregation of the dry sand bin of a dry-mixing mortar station, in particular to a dry sand bin and a method for preventing segregation. Background technique [0002] At present, the storage warehouse for storing dry sand in the dry-mixed mortar station mainly adopts a vertical drop structure, so that the dried dry sand directly falls into the warehouse. Due to the large internal drop of the warehouse and different particle sizes ( 0-5mm) dry sand has different specific gravity, and the speed of free fall is different. During storage and accumulation, dry sand naturally forms a cone shape, and dry sand with finer particle size naturally accumulates upward with the cone, while relatively When the dry sand material with coarser particle size slides down naturally from around the cone, it is very easy to produce secondary separation, which leads to the "segregation...

[0002] At present, the storage warehouse for storing dry sand in the dry-mixed mortar station mainly adopts a vertical drop structure, so that the dried dry sand directly falls into the warehouse. Due to the large internal drop of the warehouse and different particle sizes ( 0-5mm) dry sand has different specific gravity, and the speed of free fall is different. During storage and accumulation, dry sand naturally forms a cone shape, and dry sand with finer particle size naturally accumulates upward with the cone, while relatively When the dry sand material with coarser particle size slides down naturally from around the cone, 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 the finished dry-mixed mortar

In addition, due to the free-falling dry sand material, the dry sand temporarily stored at the bottom of the silo is further compacted, resulting in dirty and unsmooth discharge from the discharge port of the dry sand silo, which adversely affects the normal use of the dry sand silo. Even shorten its service life, accelerate the aging speed of equipment, resulting in an increase in production costs
