Description
Technical field
The utility model relates to a kind of Blowing stopper.
Background technology
Blowing stopper divides coventional type, pressure resistant type, high temperature resistant type three major types.
Coventional type: can be used on the usual material of less than 80 degree and normal temperature, it can continuous uniform to feed in conveying pipeline, and system be separated the portion of gathering dust, it again can as discharger function.
Pressure resistant type: it adopts dead front type rotor, can be widely used in suction send on formula, pressure sending type flow delivery systems and negative pressure transportation equipment, it can ensure that the stream pressure in delivery pipe does not leak, can safety conveying and receive knot material, so be called ten thousand flappers in this respect, it not only can be withstand voltage, has both coventional type function simultaneously.
High temperature resistant type: different with the temperature rise of feed opening because warm confrontation body expands impact according to mass transport, and to bearing and oil seal system unfavorable, it separates the casing part that machinery contacts with material, can be safe bearing operation and oil seal system not normally be worked by handing over temperature to affect, this series products is not only high temperature resistant, can also for due to the conveying of suction temperature material and metallic powder and acceptance, there is good effect because this type objects has penetrance, penetrate oil sealing arrangement material and directly enter bearing, cause running not to be subject to and damage machinery, there is exterior feature just, it can not contact with material.
Blowing stopper is for installing the discharge gate place of the discharger worked under negative pressure, top accepts the material that discharger is discharged, and relies on the impeller rotated to play a part convey materials, is responsible for again the effect of sealing, prevent from sucking air from discharge gate in process of pneumatic transmission, ensure the normal discharge of discharger.
But, owing to all there is certain roughness in Blowing stopper cabinet wall of the prior art and impeller surface, therefore, when Blowing stopper accepts the material that is easily sticky or the easily moisture absorption that discharger discharges, all can binding material on cabinet wall and impeller surface, and period of service has been grown, one deck material can be formed at cabinet wall and impeller surface, of long duration can form lump, the mass transport amount of Blowing stopper gently then can be made to reduce, heavy then can stuck impeller, thus damage Blowing stopper; For this technological deficiency, in prior art, prior art proposes to increase the clearance space of Blowing stopper cabinet wall and impeller surface thus reduces feed blocking, but due to the increase in gap, directly can cause the service efficiency of Blowing stopper; Or by arranging plastic cement or antiseized paste layer at Blowing stopper cabinet wall thus reducing blockage problem, but normally use because such paste layer needs constantly to change guarantee.So improvement of the prior art still exists obvious technological deficiency, thus make the best result of use of Blowing stopper out of reach.
