Technical field
The utility model is related to feeding device, and in particular to a kind of powder charging negative pressure device.
Background technology
In current electronic chemical product production, for the requirement more and more higher of powder material granularity, especially with sub-micro
Rice, nanometer particle size powder granule it is more and more, these materials are small, lightweight due to density, generally using the side that directly adds
Formula can cause serious dusting problem, not only cause the deviation of weighing feeding quantity, and dust pollution workshop condition, harm
Producers' health.And for the no quantitative function of charging of powder, it is impossible to learn the situation of charging.
Utility model content
In view of the shortcomings of the prior art, the purpose of this utility model, which is aimed to provide, a kind of can be prevented effectively from the powder of dust from flying
Body charging negative pressure device.
To achieve the above object, the utility model is adopted the following technical scheme that：
A kind of powder charging negative pressure device, including negative pressure equipment and vacuum cavity；The vacuum cavity is set to top
Cylindric, bottom is in inverted cone mesa-shaped structure, charging aperture is offered above vacuum cavity, in the inverted cone mesa-shaped of vacuum cavity
Structural base offers discharging opening；The negative pressure equipment is arranged at the top of vacuum cavity, and negative pressure equipment includes negative-pressure air fan and mistake
Filter screen, the negative-pressure air fan includes exhaust outlet and air entry, and negative-pressure air fan is arranged on vacuum chamber by exhaust outlet in the way of outwardly
The top of body, is connected between negative-pressure air fan and vacuum cavity；Screen pack is installed at the air entry.
It is used as a kind of optimization of the present utility model, vertical line direction and vacuum cavity of the charging aperture along vacuum cavity inwall
Connection.
As a kind of optimization of the present utility model, described charging aperture one end is connected with material sucking mouth by flexible pipe.
As a kind of optimization of the present utility model, the charging aperture is additionally provided with control valve.
As a kind of optimization of the present utility model, the control valve is also associated with timing controller, timing controller control
Control valve on off state processed.
As a kind of optimization of the present utility model, the discharging opening is connected with tipping tube.
As a kind of optimization of the present utility model, the mesh number of the screen pack is set to more than 300 mesh.
The beneficial effects of the utility model are：
1) control valve is connected with timing controller, timing controller control control valve switching device, by timing come
The amount of powder is controlled, quantitative function is realized.
2) material forms helical form, energy because specifically entering discharge position and inverted cone mesa-shaped inwall, material in vacuum cavity
Powder material is isolated well and concentrates on discharging opening.
3) being obliquely installed for discharging opening connecting tube plays certain cushioning effect to feeding intake, and weakens the speed of material, effectively keeps away
Exempt from liquid splash and dusting problem.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Reference：1st, vacuum cavity；11st, filter screen；12nd, negative-pressure air fan；13rd, exhaust outlet；2nd, charging aperture；3rd, tipping tube；
4th, discharging opening；5th, control valve；6th, material sucking mouth.
Embodiment
Below, with reference to accompanying drawing and embodiment, the utility model is described further：
As shown in figure 1, a kind of powder charging negative pressure device, including negative pressure equipment and vacuum cavity 1；The vacuum cavity 1
It is set to top cylindrical, bottom is in inverted cone mesa-shaped structure, charging aperture 2 is offered in the top of vacuum cavity 1, in vacuum chamber
The inverted cone mesa-shaped structural base of body 1 offers discharging opening 4；Vertical line direction of the charging aperture 2 along the inwall of vacuum cavity 1 with it is true
Cavity body 1 is connected, and material can be made to enter from the tangent position of the inwall of vacuum cavity 1, the inverted cone mesa-shaped in vacuum cavity 1 is added
Structure, when the material is entered vacuum cavity 1, by material shape curl, material shape curl is rotated, and can be divided well
Powder material is separated out, and material is concentrated on into discharge in discharging opening 4, is conducive to powder to concentrate in together, it is to avoid dust from flying shadow
Ring workshop condition.Described one end of charging aperture 2 is connected with material sucking mouth 6 by flexible pipe, by material sucking mouth 6 by material inspiration vacuum cavity 1
It is interior.The charging aperture 2 is additionally provided with control valve 5, and the control valve 5 is also associated with timing controller, timing controller control
The on off state of control valve 5 processed；, just can be indirectly because the suction speed of material sucking mouth 6 is identical, therefore by controlling the time of suction
The amount of control suction material；According to the actual requirements, setting time is changed timing controller, and suction duration reaches setting time
Afterwards, timing controller control control valve 5 is closed, and stops charging.
The negative pressure equipment is arranged on the top of vacuum cavity 1, and negative pressure equipment includes negative-pressure air fan 12 and screen pack 11, described
Negative-pressure air fan 12 includes exhaust outlet 13 and air entry, and negative-pressure air fan 12 is arranged on vacuum cavity by exhaust outlet 13 in the way of outwardly
1 top, is connected between negative-pressure air fan 12 and vacuum cavity 1；Negative-pressure air fan 12 siphons away the air in vacuum cavity 1, protects
Hold the clean and tidy of device, when material from charging aperture 2 enter it is fashionable material can be rotated in the inside spin of vacuum cavity 1, material rotating
Dust tiny around is also driven in journey, material is concentrated in together while rotating, therefore gravity can increase, due to gravity
Effect material can drop and be discharged from discharging opening 4.The discharging opening 4 is connected with tipping tube 3, and being obliquely installed for tipping tube 3 can allow
Material plays certain cushioning effect during discharging, the problem of being prevented effectively from dust from flying during entirely feeding, and realizes
The purpose of clean manufacturing.Screen pack 11 is installed at the air entry, the mesh number of the screen pack 11 be set to 300 mesh with
On, siphoned away when preventing material from being rotated in vacuum cavity 1 by negative-pressure air fan 12.
It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various
It is corresponding to change and deformation, and all these change and deformation should all belong to the protection of the utility model claim
Within the scope of.
