The fluidized recirculation device has the advantages that the structure is simple, the site installation is convenient, the connecting plate only needs to be directly on the side wall of the storage bin on site; simultaneously, the control is simple, and the gas flow only nees to be regulated by a regulating valve; and the vulcanizing and unloading effect is extremely good for powder materials.
Description
Technical field
The utility model relates to the feeding system of steelshop molten iron preprocessing station, particularly a kind of fluidization circulating device.
Background technology
In the feeding system of steelshop molten iron preprocessing station, no matter be desulfurization, dephosphorization or desiliconization, the material of employing all is a pulvis, raw meal particle size≤3mm.In order to meet the needs of production, often storage bin is all bigger, and the feed bin volume reaches 60～100m
3About, can store like this and produce required use amount in 2～3 days.But material is long-term stored in the storage bin, and the position to the closing in blanking of feed bin bottom the material compacting often takes place, normally the situation of blanking.At this situation, the domestic main at present method that increases hopper wall vibrator or the anti-locking device of feed bin vibration that adopts.
The anti-locking device of hopper wall vibrator or feed bin vibration is to adopt resonance principle basically, utilizes adjustable high-frequency vibration and impulsive force to prevent and remove phenomenons such as material arch camber in feed bin, the hopper, obstruction.This equipment mainly is made up of vibrating motor, stand and tie bolt etc., and electric specialty also needs wiring and supporting control box.This equipment is more remarkable for the result of use of block large granular materials, but for viscosity and fine particle material, broken arch ability will significantly reduce.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, task of the present utility model provides a kind of fluidization circulating device, and it has solved the problem that is difficult for the fluidization discharging for viscosity and fine particle material and pulvis material.
Technical solution of the present utility model is as follows:
A kind of fluidization circulating device comprises circulating pipe, carriage, metallic hose, nozzle, connecting panel and web plate;
Described circulating pipe connects metallic hose by bracket support on the circulating pipe, metallic hose is connected nozzle, is provided with nitrogen inlet with circulating pipe bonded assembly intermediate duct end;
Described connecting panel field welding is on the storage bin sidewall;
Described web plate is installed in the round mouth place that storage bin tapering side is offered, and web plate is connected with the nozzle that is loaded on the metallic hose end.
Described metallic hose is provided with ball valve.
Flange alive is equipped with at described nitrogen inlet place.
The control cock that is used for the adjustments of gas flow is housed on the described intermediate duct.
Fluidization circulating device of the present utility model is particularly useful for the pulvis material, and raw meal particle size≤3mm, circulating device are installed in the storage bin bottom, can prevent that material from stopping up.
Fluidization circulating device of the present utility model has the following advantages: simple in structure, on-site installation is convenient, directly the connecting panel field welding is got final product at the storage bin sidewall; Control simultaneously is simple, gets final product by control cock adjustments of gas flow; Has goodish sulfuration discharging effect for the pulvis material.
Description of drawings
Fig. 1 is the structural representation of a kind of fluidization circulating device of the present utility model.
Fig. 2 is the perspective view of Fig. 1 fluidization circulating device.
Reference numeral:
1 is carriage, and 2 is connecting panel, and 3 is web plate, and 4 is nozzle, and 5 is ball valve, and 6 is metallic hose, and 7 is circulating pipe, and 8 are movable joint, and 9 is nitrogen (N
2) inlet.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
Referring to Fig. 1 and Fig. 2, a kind of fluidization circulating device of the present utility model mainly is made up of carriage 1, circulating pipe 7, connecting panel 2, metallic hose 6, nozzle 4, web plate 3 and ball valve 5.
Circulating pipe 7 is supported by carriage 1.Connect metallic hose 6 on the circulating pipe 7, metallic hose 6 is connected nozzle 4.An end is provided with ball valve 5 on the metallic hose 6, and the other end is provided with movable joint 8 on the metallic hose 6.Be provided with nitrogen (N with circulating pipe 7 bonded assembly intermediate duct ends
2) inlet 9.Nitrogen (N
2) entrance 9 is equipped with flange alive.Control cock is housed on intermediate duct, can be used for the adjustments of gas flow.
As shown in FIG., connecting panel 2 field welding are on the storage bin sidewall.Web plate 3 is installed in the round mouth place that storage bin tapering side is offered, and web plate 3 is connected with the nozzle 4 that is loaded on metallic hose 6 ends.
The real work form of fluidization circulating device of the present utility model is as follows:
The version of fluidization circulating device is mainly by circulating pipe, flexible pipe, nozzle, and several parts such as ball valve are formed; Storage bin is offered round mouth with the side of feed bin tapering when design simultaneously, and circulating device is provided with the corrosion-resistant steel web plate at the round mouth place, and nozzle is arranged before the web plate.
Working process is: nitrogen (N
2) entrance of receiving the fluidization circulating device by intermediate duct, circulation on circulating pipe, nitrogen leads to the nozzle place by being connected on the metallic hose on the circulating pipe, and the nozzle nitrogen blowing blows in the storage bin by the aperture on the corrosion-resistant steel web plate.The place ahead of nozzle is provided with a manual ball valve, is used for the opening and closing of nitrogen.The flow that a control cock can adjustments of gas is set on intermediate duct.Principle of work is exactly to blow into the bar pressure that nitrogen pressure in the storage bin is higher than storage bin, and at this moment air-flow blows afloat the material of bottom in the storehouse and seethes, and reaches cure efficiency, discharging rapidly.
In sum, the advantage that fluidization circulating device of the present utility model has is: simple in structure, on-site installation is convenient, directly the connecting panel field welding is got final product at the storage bin sidewall; Control simultaneously is simple, gets final product by control cock adjustments of gas flow; Has goodish sulfuration discharging effect for the pulvis material.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the utility model, and be not with opposing qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claim the variation of the foregoing description, modification etc.
