Description
Technical field
The present invention relates to a kind of rotary table feeder, particularly relate to a kind of rotary table feeder utilizing air curtain to seal, belong to material transfer equipment technical field.
Background technology
Rotary table feeder is also known as Rotary feeder, revolution feeder, and its inner critical component is the rotor being with multiple radial vane, and the material of top feed bin falls filling cavity between the blades by deadweight, and material draws off from lower mouth along with the rotation of rotor.Rotary table feeder structure is simple, volume is little, is requiring that the little occasion of feed inlet and outlet pressure reduction has a wide range of applications, the lock gas charging gear of Chang Zuowei tobacco, grain, cement, the industry enclosed delivery system such as to build the road.
In order to ensure that rotor can operate flexibly; must reserve certain gap between rotor and housing, but material but easily enters the problems such as this gap results in blockage, rotor is stuck, user has to often shut down cleaning; troublesome poeration, impact are produced, and also reduce the service life of feeder.The existence in above-mentioned gap between rotor and housing, causes the poor sealing performance of rotary table feeder, sometimes forces feeding manner by changing interruption into continuously, and flow process can not serialization, reduces the efficiency of discharging.In order to strengthen the leak tightness between import and export, some rotary table feeders addition of rubber weather strip on rotor, but rubber weather strip can wear and tear after using for a long time, and abrasive particle will be mixed among material, and this does not obviously allow for industries such as food.In addition, after rubber strip wearing and tearing, can not get timely compensation, need regularly to shut down to change to ensure clearance seal, have impact on production process.Therefore, research and development go slick, stifled card, good seal performance meet the rotary table feeder that food hygiene requires, are of practical significance very much for tobacco, food engineering.
Summary of the invention
The object of the invention is, easily stifled card, cleaning and the problem such as maintenance workload large, input and output material efficiency low poor for existing rotary table feeder leak tightness, to provide between a kind of rotor and shell inner surface without wear and tear, good airproof performance, disassembly, cleaning conveniently, block up block, go slick, the rotary table feeder of the novel structure utilizing air curtain to seal that work efficiency is high.
To achieve these goals, the technical solution used in the present invention is: a kind of rotary table feeder utilizing air curtain to seal, be made up of cambered surface vane rotor, housing, limiting valve, feed inlet and outlet, swivel joint, outboard bearing, large small end cover, taper sheath etc., it is characterized in that, cambered surface vane rotor is hollow structure, and it is formed by the connection of double end stud, nut and annular gasket by hollow shaft, cambered plate, interior outer panel; Cambered plate is uniformly distributed at the circumferencial direction of cambered surface vane rotor, and interior plate is provided with the deep-slotted chip breaker corresponding with cambered plate; Be provided with endplay between the top of every adjacent two pieces of cambered plates, pressed gas sprays to the inside face of housing by this endplay, forms radial axial dynamic seal (packing) air curtain; Be provided with circular clearance between interior outer panel, pressed gas sprays to the inside face of housing by this circular clearance, defines the sealing air curtain of annular, realizes side seal in the both sides of cambered surface vane rotor.
In such scheme, the inside and outside side plate of described cambered surface vane rotor is tightly placed on taper sheath respectively; Interior plate has waist shaped hole, and outer panel is provided with the limiting stopper controlling inside and outside side sheet room distance.
In such scheme, described housing has revolution bodily form hollow chamber structure, and cambered surface vane rotor is positioned at the hollow chamber of housing.
In such scheme, the hollow shaft of described cambered surface vane rotor is supported on large end cap by outboard bearing; The top of housing is provided with inlet point, bottom is provided with discharging opening.
In such scheme, the quantity of the cambered plate on described cambered surface vane rotor is 3 to 20 pieces.
In such scheme, the one end open of described hollow shaft, the other end is closed, and the hollow shaft between two interior plates has some strip shape air drains.
In such scheme, whole cambered surface vane rotor is removably connected by taper sheath, double end stud, nut, annular gasket and deep-slotted chip breaker etc.
The invention has the beneficial effects as follows: by the pressed gas of circular clearance ejection between the pressed gas of cambered plate top endplay ejection, interior outer panel, define the special construction of closed air curtain sealing.Only need control gaseous tension with flow just can reach desirable sealing effectiveness, can prevent from backflowing and the generation of second-time breakage phenomenon, can not material be accumulated.Cambered surface vane rotor does not contact with shell inner surface, not wearing and tearing, the long service life of parts; The processing request in the gap of cambered surface vane rotor and housing can relax, and reduces tooling cost.Because cambered surface vane rotor does not contact housing, so go slick, both can rotate forward and also can reverse; Feeding uniformly continous, reliable operation.This rotary table feeder is Demountable, convenient disassembly, cleaning are easily, be applicable to the continus convergence of bulk cargo of high pressure, high temperature, material properties complexity, especially be suitable as conveying food stage, pharmaceutical grade material noncontact rotary seal lock gas charging gear, the upgraded product that the industry air-tightness such as food, medicinal material, metallurgy, petrochemical industry, building materials, electric power require higher rotary table feeder can be become.
