A pneumatic flow guiding device for the granular material storage tank is composed of a tank container, several parallel compressed air chambers on the bottom of tank and with nozzle, an air compressor for filling the compressed air in said air chamber, the transverse partitions for changing the airflow direction, the ridges in the tank, and a fluidized bed.
Description
Affiliated technical field
The present invention relates to a kind of powder and granule shape material guiding device, especially relate to a kind of guiding device of powder and granule shape material jar type transportation means.
Background technology
Existing powder and granule shape material jar generally adopts the pressure of high pressure air and rheomorphism to draw off powder and granule shape material, for making powder and granule shape material be easy to draw off to the greatest extent, all be provided with bigger fluid bed in jar shape material container, its ventilative canvas that is mostly that high pressure gas are passed from bottom to top and fixedly is laid on container bottom makes goods fluid.For making material move to the fluid bed discharging opening, must being easy to produce the clout part again in container, fixing metal hang plate baffle is housed is guiding device, and material draws off along sliding into the fluid bed discharging opening under the hang plate baffle by deadweight.These guiding devices make in jar shape material container actual load space be the V grooved or funnel tapered, also saving the swash plate baffle, directly container to be made V grooved or funnel tapered.
A kind of " X type fluid bed " utility model patent (CN2487690Y) was disclosed on April 24th, 2002 as the Chinese patent communique, it is the inner guiding device of a kind of improved powder grain material cylindrical tank shape transport trolley, the intermediate triangle position of its principal character two porous pieces about the common X type fluid bed tilted conical baffle that respectively is welded, the folded middle part, two inclined-planes of this tilted conical baffle is provided with the keel type gusset, can reduce the fluidisation angle of X-shaped fluid bed like this, improve space effective rate of utilization in the tank body, also can avoid the fluidisation dead angle, reduce the surplus ratio of powder grain material.These guiding devices all have its weak point: 1, the restriction owing to the powder grain material angle of repose produces the fluidisation dead angle, and fluid bed and baffle must keep certain gradient, take loading space.2, the gasification materials gasification done of canvas is relatively poor, and the long-term use meeting vortex phenomenon occurs in the middle part of fluid bed, causes container bottom that hang plate need be installed, and increases cost and deadweight.3, fluid bed maintenance cost height.4, V-type or tapered container are made relative complex, and can raise center of deadweight, reduce the safety of bulk powder goods tanker.5, air compressor only provides pressure and fluidisation effectiveness, and the airflow kinetic energy of high pressure air fails to be utilized.And air compressor air output commonly used has at present reached ten cubic meter per minutes, has enough kinetic energy can supply to utilize.
And for example the Chinese patent communique on February 11st, 2004 disclosed " a kind of guiding device of powder and granule shape material transport trolley " utility model patent (ZL03223270.5), it is a kind of guiding device that utilizes high pressure air kinetic energy, its principal character is to blow material by the air-flow that air blast nozzle sprays to slide to discharging opening, and utilizes the rotation of air-flow that material is concentrated to discharging opening.This guiding device has its weak point: if 1 container is bigger, air blast nozzle is during away from discharging opening, because the diversity of air-flow, propelling thrust disperses, and has clout.2, in order to utilize the rotation of air-flow, container bottom must be made circle.For elongated vessel, must be divided into many storehouses section, increase discharging opening quantity, increase cost.
And for example the Chinese patent communique on February 11st, 2004 disclosed " a kind of changeable type guiding device of powder and granule shape material transport trolley " utility model patent (ZL03223271.3), be that a kind of high pressure air kinetic energy that utilizes makes the container bottom distortion produce the device of water conservancy diversion dip plane, its principal character is to be easy to produce fluidisation dead angle part air bag is installed in container, air bag expands under the effect of high pressure air, form baffle, material is concentrated to discharging opening.This guiding device has its weak point: the material that 1, lacks large-scale air bag.2, the installation and maintenance cost height of large-scale air bag.3, for elongated vessel, must be divided into many storehouses section, increase discharging opening quantity, increase cost.
Summary of the invention
Purpose of the present invention just provides a kind of pneumatic guiding device that is loaded on the powder and granule shape material transport vehicle, utilizes the power of high pressure draft, and the vertical shaft of cooperation weight of material and container bottom and the shape of zanjon improve the efficient of air-flow power.Both can abandon large-scale canvas fluid bed and fixing or variable baffle, and can improve load factor and raising discharge rate in the container again, and can not produce the fluidisation dead angle simultaneously, and needn't increase container cost, reduce the center of deadweight of transportation means.Be applicable to various large-scale and elongated containers.
For achieving the above object, the guiding device that is loaded on powder and granule shape material jar shape transportation means of the present invention, comprise a jar shape material container, it is characterized in that: shape high pressure air chamber, little volume strip shape pinnacle is installed side by side at jar shape material container inner bottom part, form ditch between each air chamber, material slides along gas chamber sidewall because of the action of gravity meeting, gathers at the bottom of ditch.Bottom at ditch is installed the high pressure air nozzle continuously, and the high pressure air of drawing in the air chamber blows material, makes material move in ditch, slides to discharging opening.In order under the prerequisite that does not increase the air chamber volume, to increase the degree of depth of ditch, improve the centrality and the active distance of air-flow thrust, install on the pinnacle of air chamber and vertically increase ridge.Lateral partitions is installed to destroy the eddy current that air-flow produces.Vertically increase ridge and cooperate, form the staple arranged side by side that the ditch communications and liaison are arranged at the bottom with lateral partitions.Material in each well can after bottom of trench is met horizontal high pressure draft, can connect the hole and move to another shaft bottom because of the weight bottom of trench that glides by the bottom of trench at the bottom of the lateral partitions.Under gravity and the synergy of bottom of trench high pressure draft thrust, material connects the hole along bottom of trench and moves continuously between well and well, slides to discharging opening in vertical shaft.
The part of discharging opening and small-sized fluidized bed is consistent with conventional art.But the design area of fluid bed is more flexible, therefore can improve fluidization efficiency.
The invention has the beneficial effects as follows: this guiding device simple possible, dividing plate with increase that ridge is vertical to be installed, it is few to take the container effective volume, can improve the effective volume rate of transportation means container, no fluidisation dead angle, material does not have surplus ratio, abandons large-scale canvas fluid bed and uses small-sized canvas fluid bed instead, improve fluidization efficiency, accelerate discharge rate.The manufacturing of simplified apparatus is installed, cost-cutting.
