Description
Technical field
The present invention relates to a kind of vacuum feeder, particularly relate to row's type continuous vacuum feeder between one.
Background technology
Vacuum feeder is also referred to as powder delivery system (being called for short PTS), is now in the popularity stage both at home and abroad, this equipment
Application instead of before man-handling of materials and batch turning, effectively prevent dust from flying, and relatively simple for structure, use this equipment
Decrease dust pollution and save labour force.But current vacuum feeder employed both at home and abroad is clearance-type, there is blanking
Having some setbacks, material sucking port is regurgitated, and fed distance is short, inefficient problem.And farsighted distance or large-tonnage powder conveying are often
Employing malleation carries, and carries out malleation air blast to the lower section long pipeline equipped with Blowing stopper even feeding by high pressure positive blower or compressed air
Realizing diluted phase transport, conveying end also needs to join cyclone separator, Blowing stopper and cleaner unit and completes, and therefore, not only equipment is numerous
Many, take up an area space greatly, and cost is the highest, the most easily occur at pipe joint that dust is revealed and serious environment pollution, even can
There is dust explosion.High efficiency conveying can not be met for clearance-type vacuum handling, and malleation conveying cost height exists safety
This situation of hidden danger, (had both had negative pressure transportation characteristic, and had had again the farsighted distance of malleation and produce greatly to meet market widespread demand again
Amount conveying, also wants economical and practical and there is not potential safety hazard) and to develop CVF continuous vacuum feeder specially (the most continuous
Formula negative pressure transportation equipment).
Either plate valve formula or butterfly valve type vacuum feeder, broadly falls into clearance-type vacuum feeder, is all to close at baiting valve
When closing, material is first drawn onto in feeder container by the captivation by vacuum, then the material in feeder container when vacuum is closed
When baiting valve is opened by being gravitationally fallen in equipment or the container of lower section, then under enter again vacuum intake state after complete material,
The alternate cycles vacuum intake so gone round and begun again and self-weight blanking action, reach the purpose of conveying, so up to the present,
The no matter that vacuum conveying apparatus in home and abroad, is all clearance-type vacuum feeding, there is problems in that
1. efficiency is low, the not blanking when suction, the not suction when blanking, discontinuous conveying material on the time but staggered
Type；
2. conveying yield is unstable, and particularly air driven jet vacuum generator does vacuum source, because vacuum depends on compression
Air produces, and compressed-air actuated pressure often 0.4 ~ 0.8MPa fluctuate, then the vacuum of vacuum generator the most just with
The fluctuation of compressed air pressure and time height time low, the transporting velocity of respective clearance formula vacuum feeder is the most just with the height of vacuum
Change and sometimes fast and sometimes slow.The square structure of jet type vacuum generator own also can only bear clearance-type and produce vacuum, it is impossible to time long
Between vacuum-resistant.
The only electric vacuum pump of most economical material benefit, but electric vacuum pump does clearance-type vacuum feeder and there is also two sides
The defect in face: 1) relatively big if existing for vacuum source waste at vacuum feeder top vacuum tube equipped with Pneumatic three-way ball valve, work as suction
During material, vacuum source is just utilized acting, and vacuum pump the most just is switched to inhale extraneous air by tee ball valve when being switched to blanking
Do not do work, i.e. the wasting of resources；2) if existing for feed blocking filter element group at vacuum feeder top vacuum tube equipped with pneumatic ball valve,
Because of when being switched to blanking vacuum pump can not inhale outside air result in the vacuum of vacuum pipe, vacuum tank etc. increase to-80 to-
90KPa, than suction time vacuum (general-45 ~-60KPa) much higher, result in when again switching to suction fine vacuum to
Coarse vacuum changes, and the material that firm inspiration is gone gets lodged in filter element group the most tightly and causes suction to have some setbacks around equipment barrel, blanking
Time air accumulator with regard to a large amount of compressed air of moment blowback or nitrogen also be difficult to clearly fall blocking material.If doing vacuum source with high pressure positive blower
And the vacuum relatively low (general-23 KPa) produced, high conveying at a distance cannot be realized at all.
With there is the plain type continuous vacuum feeding of different structure above, be want suction equipment (as wet granulator,
Mixer, reactor etc.) it is provided with the interface of material sucking port and evacuation, material sucking port connects suction flexible pipe and is used for feeding, and vacuum connects
Mouthful it is that first filter element group through installing, to carry out gas solid separation, then receives Motorized vacuum source (such as water ring vacuum pump, repeatedly with pipeline
Vacuum pump, rotary-vane vaccum pump etc.).First airtight for equipment container and only allow material sucking port and vacuum port unimpeded before conveying, equipment exists
Just material is introduced in equipment container from suction tube under the effect of vacuum, then after filter element group carries out gas solid separation, air-flow is arranged
To Motorized vacuum source.Its conveying material occur as soon as after a short time can not suction, because filter element cannot complete when vacuum intake
Self-cleaning (blowing down the material of filter opening and periphery by compressed air, allow filter element remain unimpeded state) results in blockage, and one blocks up
Plug suction tube in vacuum the most slowly reduce, the most progressively cause cannot suction, wanting the most unimpeded conveying must be continually filter
Core takes out and cleans up or change filter element, and this makes troubles to user, and medicine is also exposed and frequently contacts with operator,
Cannot normally use at all and reach GMP requirement.
