Description
Technical field
The present invention relates to vacuum feeder field, relate in particular to a kind of row's type continuous vacuum feeder.
Background technology
Vacuum feeder is also referred to as powder delivery system (being called for short PTS), now, both at home and abroad in generally promoting the stage, the application of this equipment has replaced former man-handling of materials and batch turning, has effectively prevented dust from flying, and relatively simple for structure, use this equipment to reduce dust pollution and save labour power.But current vacuum feeder employed both at home and abroad is clearance-type, exists blanking to have some setbacks, and material sucking port is regurgitated, and fed distance is short, the problem that efficiency is lower.And farsighted distance or large-tonnage powder conveying often adopt malleation to carry, by high pressure positive blower or pressurized air, to the below long pipeline that Blowing stopper even feeding is housed, carry out malleation air blast and realize dilute phase conveying, carrying end also to need to join cyclone, Blowing stopper and dust exhaustor completes, therefore, not only equipment is various, and occupation of land space is large, and cost is also quite high, pipeline connection place is also prone to that dust is revealed and serious environment pollution even dust explosion can occur.For clearance-type vacuum handling, can not meet high efficiency carries, and malleation carries cost height to have this situation of potential safety hazard, in order to meet market widespread demand, (both there is negative pressure transportation characteristic again, there is again the large output of the farsighted distance of malleation and carry, also want economical and practical and do not have potential safety hazard) and develop specially CVF continuous vacuum feeder (also claiming continuous negative pressure load transfer device).
No matter be plate valve formula or butterfly valve type vacuum feeder, all belong to clearance-type vacuum feeder, all that the attractive force by vacuum is first drawn onto material in feeder container when baiting valve is closed, again the material when vacuum is closed and in feeder container when baiting valve is opened by gravity fall to below equipment or container in, then after having descended material, enter again vacuum intake state, the alternate cycles vacuum intake going round and beginning again like this and self-weight blanking action, reach the object of conveying, so up to the present, the that vacuum conveying apparatus in home and abroad no matter, it is all clearance-type vacuum feeding.
The efficiency of clearance-type vacuum feeder is low, not blanking when suction, not suction when blanking, discontinuous convey materials on the time but staggered.
Conveying output is unstable, particularly pneumatic jet formula vacuum generator is done vacuum source, because depending on pressurized air, vacuum produces, and compressed-air actuated pressure often fluctuates at 0.4 ~ 0.8MPa, low when high when the degree of vacuum of vacuum generator is also just with the fluctuation of compressed air pressure so, the delivery speed of respective clearance formula vacuum feeder is also just sometimes fast and sometimes slow with the height variation of degree of vacuum.The square structure of jet type vacuum producer own also can only bear clearance-type and produce vacuum, for a long time vacuum-resistant.The only electric vacuum pump of most economical material benefit.
Electric vacuum pump is done clearance-type vacuum feeder and is also deposited defect both ways: 1) if Pneumatic three-way ball valve is housed at vacuum feeder top vacuum lamp, just exist vacuum source waste larger, when suction, vacuum source is just utilized acting, and vacuum pump is also just switched to by tee ball valve and inhales extraneous air and do not do work, be i.e. the wasting of resources when being switched to blanking, 2) if pneumatic ball valve is housed at vacuum feeder top vacuum lamp, just there is feed blocking filter core group, vacuum pump can not be inhaled outside air and just causes vacuum pipe when being switched to blanking, the degree of vacuum of vacuum reservoir etc. increases to-80 to-90KPa, (general-45 ~-60KPa) is much higher for degree of vacuum during than suction, when being again switched to suction, just cause high vacuum to change to low vacuum, the material that just inspiration is gone just gets lodged in tightly filter core group and equipment barrel and causes suction to have some setbacks around, during blanking, storage tank is also difficult to regard to a large amount of pressurized airs of moment blowback or nitrogen the material that falls to stop up clearly.If do vacuum source and the degree of vacuum that produces lower (general-23 KPa) with high pressure positive blower, cannot realize at all and highly carrying at a distance.
Simple type continous vacuum material loading is exactly the interface that is provided with material sucking port and vacuumizes on the equipment of suction (as wet granulator, mixer, reactor etc.) wanting; material sucking port connects suction flexible pipe and is used for charging; vacuum interface is first through the filter core group of installing, to carry out gas solid separation, then receives Motorized vacuum source (as water ring vacuum pump, repeatedly vacuum pump, rotary-vane vaccum pump etc.) with pipeline.Before carrying first equipment container is airtight and only allow material sucking port and vacuum port unimpeded, equipment under the effect of vacuum just material in suction tube introducing equipment container, then air-flow is drained into Motorized vacuum source after filter core group is carried out gas solid separation.
Carry that just occur after a short time material can not suction, because cannot completing self-cleaning when the vacuum intake, filter core (by pressurized air, blows down the material of filter opening and periphery, allow filter core remain unimpeded state) result in blockage, degree of vacuum in stopping up suction tube slowly reduces, just progressively causing cannot suction, wanting unimpeded conveying must be continually take out filter core to clean up or renew cartridge more again, this makes troubles to user, and medicine is also exposed and frequently contacts with operator, cannot normally use and reach GMP requirement at all.
