Description
Technical field
The present invention relates to a kind of rotary table feeder, more particularly to a kind of rotary table feeder sealed using air curtain, belong to thing
Expect conveying equipment technical field.
Background technology
Rotary table feeder is also known as Rotary feeder, revolution dispenser, and its internal critical component is with multiple radial blades
Rotor, the material of top feed bin fall the cavity of filling between the blades by deadweight, and material is expected with the rotation of rotor from bottom
Mouth is drawn off.Rotary table feeder is simple in construction, small volume, iing is required that the small occasion of feed inlet and outlet pressure difference has a wide range of applications, often
As tobacco, grain, cement, the industry enclosed induction system such as build the road lock gas charging gear.
In order to ensure that rotor can be operated flexibly, certain gap must be reserved between rotor and housing, but material is but
The problems such as gap results in blockage, rotor is stuck is easily accessible, user must not infrequently shut down cleaning, troublesome in poeration, influence life
Production, also reduce the service life of feeder.The presence in above-mentioned gap between rotor and housing, causes the sealing of rotary table feeder
Poor performance, sometimes forcing feeding manner, flow is unable to serialization, reduces the efficiency of discharging by continuously being changed to be interrupted.In order to
Sealing between enhancing inlet and outlet, some rotary table feeders addition of rubber weather strip on rotor, but rubber weather strip
It can be worn after long-time use, abrasive particle will be mixed among material, and this is clearly what is be impermissible for for industries such as food.In addition, rubber
It cannot in time compensate after adhesive tape abrasion and be changed, it is necessary to periodically shut down to ensure clearance seal, have impact on production process.Therefore,
Research and development go slick, not stifled card, good seal performance and the rotary table feeder for meeting food hygiene requirement, for tobacco, food work
Journey is of practical significance very much.
The content of the invention
The purpose of the present invention be for existing rotary table feeder sealing it is poor, easily stifled card, cleaning and maintenance workload it is big,
The problems such as input and output material efficiency is low, there is provided between a kind of rotor and shell inner surface without abrasion, good airproof performance, disassembly, cleaning it is convenient,
It is not stifled block, go slick, the rotary table feeder of the high novel structure sealed using air curtain of operating efficiency.
To achieve these goals, the technical solution adopted by the present invention is：A kind of rotary table feeder sealed using air curtain,
It is made up of cambered plate, interior plate, outer panel, hollow shaft, housing, feed inlet and outlet, swivel joint, taper sheath etc., it is characterised in that
Interior plate, outer panel are located at the both ends of hollow shaft respectively, and swivel joint connects with hollow shaft, and hollow shaft is provided with air inlet；Arc
Panel is uniformly distributed in the circumferencial direction of interior plate, and interior plate is provided with deep-slotted chip breaker corresponding with cambered plate, and cambered plate is stuck in arc
In shape groove；Axial gap is provided between top per adjacent two pieces of cambered plates, annular gap is provided between interior outer panel.
In such scheme, be provided with mounting hole on the interior plate, the outer panel be provided with side sheet room inside and outside control away from
Limited block.
In such scheme, the housing has revolution bodily form hollow chamber structure, the cambered plate, interior plate, outer panel
In the hollow chamber of housing.
In such scheme, the top of the housing is provided with discharging opening provided with charging aperture, bottom.
In such scheme, the quantity of the cambered plate is more than 3 pieces.
In such scheme, some strip air drains are provided with the hollow shaft.
In such scheme, the cambered plate, interior plate, outer panel are by the taper sheath, studs, nut with removable
The mode of unloading couples.
The beneficial effects of the invention are as follows：By between the pressed gas of cambered plate top axial gap ejection, interior outer panel
The pressed gas that annular gap sprays, form the special construction of closed air curtain sealing.Gas pressure and flow only need to be controlled
With regard to preferable sealing effectiveness can be reached, it can prevent from backflowing and second-time breakage phenomenon occurs, material will not be accumulated.By cambered plate, interior
The cambered surface vane rotor of the compositions such as side plate, outer panel does not contact with shell inner surface, does not wear, the service life of parts
It is long；Cambered surface vane rotor and the processing request in the gap of housing can relax, and reduce processing cost.Due to cambered surface vane rotor
Housing is not contacted, so going slick, can rotate forward or invert；Feeding uniformly continuous, reliable operation.This rotary feeding
Device is Demountable, and convenient disassembly, cleaning are easy, suitable for the continuous defeated of the complicated bulk cargo of high pressure, high temperature, material properties
Send, be particularly suitable as conveying the non-contact rotatory sealing lock gas charging gear of food-grade, pharmaceutical grade material, food, medicine can be turned into
The industry such as material, metallurgy, petrochemical industry, building materials, electric power air-tightness requires the upgraded product of higher rotary table feeder.
