Background technology
Be provided with the powder grain material transfer cask of fluid bed in existing, for allow jar interior material preferably fluidisation and allow when the discharging material discharge rapidly, thorough, its fluidisation bed surface requirement has certain gradient.Be provided with the powder grain material transfer cask of fluid bed in existing, its jar inner structure all is to be the boundary with its fluid bed bed surface, will be divided into material bin on the fluidisation bed surface and the air chamber two large divisions under the fluidisation bed surface in the tank body.The powder grain material transfer cask of this structure, its material load factor is not high, and its center of gravity is higher during loaded material; Material is contained in the big bin, and in transportation, vehicle acceleration, deceleration degree suddenly can make material spring up in the storehouse, influences the operation stability of transport trolley.
Summary of the invention
The utility model provides a kind of powder grain material transfer cask, and its main purpose is the height of gravitational center of loaded material when reducing tank body and using, and improves the load factor of tank body simultaneously.
To achieve these goals, the scheme that the utility model adopts is: it includes tank body, be located at the air chamber of tank base and be located at the fluidisation bed surface of described air chamber item face, bottom in the described tank body is provided with dividing plate, and the each several part that described tank body is separated to form by this dividing plate is equipped with described fluidisation bed surface.
Above-mentioned tank body can be made of the cylindrical shell of closed at both ends, and described dividing plate can be laterally or vertically is arranged in the described cylindrical shell.
Because adopt such scheme, the utility model compared with prior art has following beneficial effect:
1, the load factor height of tank body.In jar dividing plate being set can make the material on the fluidisation bed surface be divided into a plurality of separate bins, under the identical condition of length of tank, fluidisation bed surface gradient, the volume of the air chamber of each bin bottom is all very little, the volume sum of each little air chamber is less than an atmospheric air chamber volume of prior art, therefore, can effectively improve the load factor of tank body.Tank body with 2 meters long 6.1 meters structures of jar of diameter is an example, is provided with two dividing plates and the three storehouse powder grain material transfer casks that form are higher by 10~20% than the existing powder grain material transfer cask load factor of not establishing dividing plate.
2, the material center of deadweight is low.The fluid bed gas chamber volume that above-mentioned powder grain material transfer cask has the powder grain material transfer cask of not establishing dividing plate now is littler, and the center of gravity that can make tank body contain material simultaneously reduces.Under the identical condition of length of tank, fluidisation bed surface gradient, be provided with a dividing plate and two storehouses powder grain material transfer cask of forming can reduce by 100~150 millimeters than the existing powder grain material transfer cask center of deadweight of not establishing dividing plate; The three storehouse powder grain material transfer casks that are provided with two dividing plates and form can reduce by 200~300 millimeters than the existing powder grain material transfer cask center of deadweight of not establishing dividing plate.Therefore can effectively reduce tank body itself and the center of gravity under loaded-up condition after adopting this structure.
3, operate steadily.Originally be potted in when using on the transport trolley, since in tank body laterally or be vertically arranged with dividing plate, the powder grain material that is contained in the tank body is separated into several fractions, compared with prior art, can reduce to cause powder grain material to gushing the height of accumulation on the tank body front end because of drive a vehicle brake suddenly or acceleration, thereby can reduce powder grain material inertia impact dynamics to tank body in transportation, make vehicle operating more steady; Simultaneously owing to adopt this structure tailheaviness to obtain bigger reduction, make the tumbling property of car load in the process of driving relatively also obtain bigger reduction.Therefore can effectively improve the stability that transport vehicle travels.
The specific embodiment
Below in conjunction with the accompanying drawing example structure of the present utility model is described in further detail.
In the example shown in Figure 1, this many storehouses powder grain material transfer cask includes the tank body 1 of the cylindrical shell formation of closed at both ends, tank body 1 in-to-in is provided with a lateral partitions 5, preceding material bin 2 that is separated to form by dividing plate 5 in the tank body 1 and back material bin 6, their bottom is respectively equipped with fluidisation bed surface 3, air chamber 4 and fluidisation bed surface 7, air chamber 8.
