Abstract
The invention provides a powder tank and a mixing station. The powder tank comprises a silo. At least two separated powder storage cavities are formed in the silo and sequentially formed in the up-and-down direction. According to the powder tank, an up-and-down silo separation structure is adopted in the powder storage cavities in the silo, leakage is not easily generated between the two adjacent powder storage cavities, and therefore the failure rate of the powder tank caused by communication of the different powder storage cavities is reduced.
Description
Technical field
The present invention relates to powder state material memory technology, more specifically, relate to a kind of powder material tank and mixing plant.
Background technology
Current, generally adopt the powder state materials such as powder material tank storage cement, fly ash, breeze.As concrete mixing plant or mortar mixing plant setting is used in conjunction with conventionally stirring system and aggregate-storing system, aggregate-storing system generally includes by a plurality of powder material tanks and forms powder memory system, to store the powder state materials such as cement.
Current powder material tank is divided into single cone powder material tank and two kinds of forms of bipyramid powder material tank, Fig. 1 shows the silo structure of bipyramid powder material tank general in prior art, the inner powder storage chamber 1 ', 2 ' that is separated into two the mutual isolation in left and right by a perpendicular dividing plate 3 ' long, planar structure of silo 100 ', two kinds of less powders of demand can be respectively charged in left and right two chambers of this bipyramid powder material tank like this, to reduce the usage quantity of single cone powder material tank, be conducive to save the space that powder material tank takies.
Two of the left and right powder storage chamber of bipyramid powder material tank is respectively arranged with feed pipe and discharging opening separately, when arbitrary powder storage chamber need to be annotated powder, the feed pipe connection of the conveying pipeline that is loaded with the powder transport vehicle that needs filling powder and corresponding powder storage chamber, by Pneumatic conveyer, make powder and pressurized air be mixed to form material gas mixture again, and make to expect that gas mixture flows in powder storage chamber by feed pipe, after material gas mixture enters in powder storage chamber, under the effect of dust collecter, most of air is discharged to the external world by dust collecter, powder is deposited in powder storage chamber.
When reinforced to a side powder storage chamber, pressure in the powder storage chamber in charging side is much larger than the pressure of charging side powder storage chamber not, when especially in powder transport vehicle, powder state material is less, operating personal reopens the moment of transfer valve filling powder state material again after powder transport vehicle is built the pressure, pressure in the powder storage chamber in charging side reaches extreme value, at this process median septum, be subject to the large compression shock of charging side powder storage chamber, when if powder material tank height is higher, the diaphragm structure intensity of perpendicular long plate shape is lower, growth along with period of service, dividing plate can be because being subject to the damage that very easily deforms of the compression shock of both sides cavity repeatedly, cause the powder storage chamber of both sides to communicate, powder is altered mutually, affect the normal use of powder material tank, cause powder material tank operational failure.
Therefore, how to improve the structure of the inner powder storage chamber of powder material tank, reduce because of the different powder storage chambers powder material tank operational failure causing that communicates be the technical barrier that those skilled in the art need solution badly.
Summary of the invention
Based on above-mentioned technical barrier, first object of the present invention is to provide a kind of powder material tank, and this powder material tank, by improving the structure of inner powder storage chamber, can reduce the fault rate that communicates and cause because of different powder storage chambers.
A kind of powder material tank provided by the invention, comprises silo, is provided with at least two isolated powder storage chambers in silo, and each powder storage chamber is arranged along the vertical direction successively.
