Description
Technical field
The utility model relates to a kind of vacuum feeder, relates 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 be in generally and promote the stage both at home and abroad, 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 present 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, carry out the malleation air blast for the below long pipeline that the Blowing stopper even feeding is housed with high pressure positive blower or pressurized air and realize the dilute phase conveying, carrying end also need join cyclone, Blowing stopper and dust exhaustor completes, therefore, not only equipment is various, and the occupation of land space is large, and cost is also quite high, pipeline connection place also is prone to that dust is revealed and serious environment pollution even dust explosion can occur.Can not meet high efficiency for the clearance-type vacuum handling carries, and malleation carries the cost height to have this situation of potential safety hazard, (both had the negative pressure transportation characteristic for the satisfying the market widespread demand again, have 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 the continuous negative pressure load transfer device).
no matter be plate valve formula or butterfly valve type vacuum feeder, all belong to the clearance-type vacuum feeder, all that the attractive force by vacuum first is drawn onto material in the feeder container when baiting valve is closed, again when vacuum is closed and the material in the feeder container when baiting valve is opened by gravity fall to below equipment or container in, then enter again the vacuum intake state after having descended material, the alternate cycles vacuum intake that goes round and begins again like this and self-weight blanking action, reach the purpose of conveying, so up to the present, the sort of vacuum conveying apparatus in home and abroad no matter, it is all the clearance-type vacuum feeding, there is following problem:
