Description

Powder transfer warehouse Technical Field The utility model belongs to the technical field of integrated grinding equipment, and particularly relates to a powder transfer warehouse. Background In the industries of concrete mixing, building material production, metallurgy and the like, the transportation and storage of powder are one of the key links, and the technical scheme commonly adopted in the industry at present is that powder is directly transported to a use site from a production place by a powder bulk transport vehicle and then blown into a silo of a mixing station by an ash pipe for temporary storage. At present, the powder consumption in the concrete stirring field is generally large, and the conventional method is to transport the powder to the site by a powder bulk vehicle and blow the powder into a silo from a silo of a stirring station by using a dust-blowing pipe. However, for some remote areas, the transportation costs are high. For remote regional projects, powder needs to be transported to the site from a central production area through hundreds of kilometers, the fuel cost and the vehicle loss are greatly increased, the bulk vehicle can only realize 'point-to-point' transportation, and the support of a regional transfer warehouse is lacking, so that multiple sites in the same area need to repeatedly call the bulk vehicle, and the resource waste is serious. Thus, a powder material transfer warehouse is provided. Disclosure of utility model The utility model aims to provide a powder transfer warehouse which has a powder transportation transfer function and solves the problems that a powder bulk vehicle is transported to the site, and ash pipe gas is blown into a warehouse from a mixing station silo, so that the transportation cost is high. In order to achieve the purpose, the utility model adopts the technical scheme that the powder transfer warehouse comprises powder silos, wherein transfer silos are arranged around the powder silos, a silo top dust remover is arranged at the top of each transfer silo, a feeding screw is connected below each transfer silo, the tail end of each feeding screw is connected with a bulk machine, the bulk machine is provided with a high-pressure fan, and an outlet of the high-pressure fan is communicated with the silo top of each transfer silo through a dust removing pipe. Preferably, the powder silo adopts a double-layer structure, the inner layer is a 304 stainless steel layer, the outer layer is a Q235B carbon steel layer, polyurethane foaming is filled between the inner layer and the outer layer, and a ceramic wear-resistant lining plate is arranged on the inner wall of the powder silo. Preferably, the bin top dust remover is a pulse back blowing type cloth bag dust remover, and a PTFE (polytetrafluoroethylene) tectorial membrane polyester filtering cloth bag is arranged inside the bin top dust remover. Preferably, the feeding screw comprises a horizontal section and an inclined section, the included angle between the inclined section and the horizontal section is 30-45 degrees, and the surface of the blade of the feeding screw is sprayed with a tungsten carbide wear-resistant coating. Preferably, the bulk machine is a telescopic bulk machine, and the outlet is provided with a gravity sensor which is interlocked with a driving motor of the feeding screw. Preferably, the high-pressure fan is a centrifugal high-pressure fan, rated air quantity is 8000-12000m 3/h, working pressure is 12-18kPa, and the fan of the high-pressure fan adopts an aluminum alloy impeller and is subjected to dynamic balance calibration. Compared with the prior art, the utility model has the advantages and positive effects that, 1. The utility model shortens the cement transportation distance and saves the powder transportation cost; 2. The utility model has the powder transportation transfer function, and solves the problems of the prior art that the powder bulk vehicle is transported to the site, the dust pipe is blown into the silo from the silo of the stirring station, and the transportation cost is higher.
