A fluidized hopper suitable for multipoint feeding comprises a storage hopper, a cylindrical structure which is provided with a charging port and a charging rotary valve on the top and a material discharging port in the bottom; a fluidized bed chassis arranged on the bottom of the storage hopper and provided with a plurality of fan-shaped air cavities; an air supply mechanism, comprising a pneumatic butterfly valve, a reducing valve and a Laffer pipe and respectively connected to the fan-shaped air cavities of the fluidized bed chassis by a distribution pipe; a pressure stabilizing exhausting filtering mechanism, comprising a belt backblow airbag filter and a centrifugal fan and arranged on the top of the storage hopper; a plurality of sucking guns uniformly distributed on parts close to the inner wall along the peripheral direction in the storage bin; and a controller respectively and electrically connected to the charging rotary valve, the pneumatic butterfly valve, the centrifugal fan and the belt backblow airbag filter; a layer of filter cloth is paved on the bottom of the chassis; and outlets of the sucking guns extend out of the storage bin. According to the fluidized hopper, materials in the storage bin are enabled to be in a fluidized state, a bed floor of the hopper is enabled to be level with the material level always, and is suitable for material sucking of multiple material sucking points.
Description
Technical field
The present invention relates to material conveying, more particularly to a kind of fluidization hopper of suitable multiple spot feed.
Background technology
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 in face：
1., due to the presence of multiple suction points, it is contemplated that the flow behavior of different powders, the material position for needing material stock hopper is put down
Together；
2. due to being multiple spot vacuum pressure conveying, it is desirable to have enough air supplement feed hopper；
3. it is probably a line conveying in view of suction pipeline, it is also possible to a plurality of line conveying, needs to keep material stock material
The pressure stability of bucket；
4. consider that material changes kind, the powder in material stock feed bin can be drained completely.
The content 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, it is ensured that all the time material position is flushed the bed of hopper, multiple suction point suctions are adapted to.
To reach above-mentioned purpose, the technical scheme is that：
A kind of fluidization hopper of suitable multiple spot feed, it includes, material stock hopper, tubular structure, and its top sets charging aperture
And charging rotary valve, bottom is provided with discharge of materials mouth；Fluid bed chassis, is arranged at the material stock feed hopper bottom, fluid bed chassis
Several fan-shaped air cavitys are provided with, the chassis surface lays a metafiltration cloth；Gas supply mechanism, it is pneumatic including what is be sequentially connected by pipeline
Butterfly valve, air relief valve, drawing cut down pipe, and are respectively connecting to the fluid bed chassis sector air cavity by distribution pipe；Voltage stabilizing exhaust gas filter
Mechanism, including the band back-blowing bag filter, the centrifugal blower that are sequentially connected by pipeline, and is arranged at material stock hopper top；
Some suction guns, are circumferentially evenly distributed at nearly inwall in the material stock feed bin, and material stock feed bin is stretched out in its outlet；Control
Device, the charging rotary valve, Pneumatic butterfly valve, centrifugal blower and band back-blowing bag filter are electrically connected with controller.
Preferably, high and low level-sensing device is set on the material stock hopper, and be electrically connected with the controller and, low level-sensing device
Position is higher than suction gun port.
Preferably, the material stock hopper top also sets an air inlet and corresponding admission line and inlet filter.
It is an advantage of the current invention that：
1. the present invention arranges fluid bed chassis by material stock feed hopper bottom and gas supply mechanism coordinates, it is ensured that the bed of hopper begins
Whole material position is flushed, and meets multiple suction gun multiple spot suctions.
2. negative pressure is formed at the suction nozzle of suction gun, so that material is inhaled in feed bin or stirred tank.
3. reduce a dead lift and make material spilling pollution on the environment.
Description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the A-A sectional views 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, it includes,

Pipe arrangement 34 is respectively connecting to the fan-shaped air cavity 21 in the fluid bed chassis 2；
Voltage stabilizing exhaust gas filter mechanism 4, including the band back-blowing bag filter 41, centrifugal blower being sequentially connected by pipeline
42, and it is arranged at the top of material stock hopper 1；
Some suction guns 5,5 ', are circumferentially evenly distributed at nearly inwall in the material stock feed bin 1, and its outlet is stretched out
Material stock feed bin 1；
Controller (not shown), the charging rotary valve, Pneumatic butterfly valve, centrifugal blower and band back-blowing bag filter
It is electrically connected with controller.
In the present embodiment, high and low level-sensing device 6,6 ' is set on the material stock hopper 1, and is electrically connected with the controller；
And, the low position of level-sensing device 6 ' is higher than suction gun port.
Preferably, the top of the material stock hopper 1 also sets an air inlet and corresponding admission line 14 and inlet filter 7.
Solid granule is from feeding rotary valve feed to material stock hopper delivery；Compressed air is through Pneumatic butterfly valve, air relief valve, drawing
Pipe, fluid bed chassis are cut down, into material stock feed bin, the tolerance for controlling to enter causes the material in material stock feed bin to be in fluid bed shape
State, it is ensured that all the time material position is flushed the bed of hopper, meets multiple suction gun multiple spot suctions.
Unnecessary gas is discharged by back-blowing bag hose dust removal process, Jing centrifugal blowers.
If the tolerance that system is provided is not enough, Jing material stocks hopper top admission line and inlet filter supplement air and enter
Enter material stock feed bin.
Material stock feed hopper bottom is provided with discharge of materials hole, and when needing discharges material, by the operation of fluidized material, material can
To be smoothly discharged out hopper.
