Description
Technical field
The present invention relates to material conveying, in particular to a kind of fluidization hopper of suitable multiple spot feed.
Background technique
Industrially it is commonly encountered the technique for being sent to multipoint reception hopper from a material stock hopper suction, it usually needs solve four sides
The problem of face:
1. due to the presence of multiple suction points, it is contemplated that the flow behavior of different powders needs the material position of material stock hopper flat
Together；
2. needing enough air supplement feed hoppers due to being multiple spot vacuum pressure conveying；
3. in view of suction pipeline may be a line conveying, it is also possible to which a plurality of line conveying needs to keep material stock material
The pressure of bucket is stablized；
4. considering that material replaces kind, the powder in material stock feed bin can drain completely.
Summary of the invention
It is an object of the invention to design a kind of fluidization hopper of suitable multiple spot feed, so that the material in material stock feed bin
In fluidized bed state, guarantee that material position flushes always for the bed of hopper, adapts to multiple suction point suctions.
In order to achieve the above objectives, the technical scheme is that
A kind of fluidization hopper of suitable multiple spot feed comprising, material stock hopper, tubular structure, top sets feed inlet
And charging rotary valve, bottom are equipped with discharge of materials mouth；Fluidized bed chassis is set to the material stock feed hopper bottom, fluidized bed chassis
Equipped with several fan-shaped air cavitys, which is laid with one layer of filter cloth；Gas supply mechanism, including it is sequentially connected pneumatic by pipeline
Butterfly valve, pressure reducing valve, drawing cut down pipe, and are respectively connected to the fluidized bed chassis sector air cavity by distribution pipe；Pressure stabilizing exhaust gas filter
Mechanism, including by the sequentially connected band back-blowing bag filter of pipeline, centrifugal blower, and be set at the top of material stock hopper；
Several suction guns are circumferentially evenly distributed at nearly inner wall in the material stock feed bin, and material stock feed bin is stretched out in outlet；Control
Device, the charging rotary valve, Pneumatic butterfly valve, centrifugal blower and is electrically connected controller with back-blowing bag filter.
Preferably, high and low level-sensing device is set on the material stock hopper, and be electrically connected the controller and, low level-sensing device
Position is higher than suction gun port.
Preferably, an air inlet and corresponding admission line and inlet filter are also set at the top of the material stock hopper.
The present invention has the advantages that
1. fluidized bed chassis and gas supply mechanism cooperation is arranged by material stock feed hopper bottom in the present invention, guarantee that the bed of hopper begins
Whole material position flushes, and meets multiple suction gun multiple spot suctions.
2. negative pressure is formed at the suction nozzle of suction gun, so that material be made to be inhaled into feed bin or stirred tank.
3. reducing manual handling and making material spilling pollution on the environment.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the embodiment of the present invention.
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Specific embodiment
Referring to Fig. 1, Fig. 2, a kind of fluidization hopper of suitable multiple spot feed of the present invention comprising,
Material stock hopper 1, tubular structure, top sets feed inlet 11 and charging rotary valve 12, bottom are equipped with discharge of materials mouth
13；
Fluidized bed chassis 2 is set to 1 bottom of material stock hopper, and fluidized bed chassis 2 is equipped with several fan-shaped air cavitys 21,
The chassis surface is laid with one layer of filter cloth 22；
Gas supply mechanism 3, including pipe 33 is cut down by the sequentially connected Pneumatic butterfly valve 31 of pipeline, pressure reducing valve 32, drawing, and by dividing
Piping 34 is respectively connected to the fan-shaped air cavity 21 in the fluidized bed chassis 2；
Pressure stabilizing exhaust gas filter mechanism 4, including pass through the sequentially connected band back-blowing bag filter 41 of pipeline, centrifugal blower
42, and it is set to 1 top of material stock hopper；
Several suction guns 5,5 ', are circumferentially evenly distributed at nearly inner wall in the material stock feed bin 1, and outlet is stretched out
Material stock feed bin 1；
Controller (not shown), the charging rotary valve, Pneumatic butterfly valve, centrifugal blower and with back-blowing bag filter
Controller is electrically connected.
In the present embodiment, high and low level-sensing device 6,6 ' is set on the material stock hopper 1, and is electrically connected the controller；
And low 6 ' position of level-sensing device is higher than suction gun port.
Preferably, 1 top of material stock hopper also sets an air inlet and corresponding admission line 14 and inlet filter 7.
Solid granule is fed from charging rotary valve to material stock hopper delivery；Compressed air passes through Pneumatic butterfly valve, pressure reducing valve, drawing
Pipe, fluidized bed chassis are cut down, into material stock feed bin, the tolerance for controlling entrance makes the material in material stock feed bin be in fluidized bed shape
State guarantees that material position flushes always for the bed of hopper, meets multiple suction gun multiple spot suctions.
Extra gas is discharged by back-blowing bag hose dust removal process through centrifugal blower.
If the tolerance that system provides is insufficient, through admission line at the top of material stock hopper and inlet filter supplement air into
Enter material stock feed bin.
Material stock feed hopper bottom is equipped with discharge of materials hole, and when needing discharges material, by the operation of fluidized material, material can
To be smoothly discharged out hopper.
