The technical scheme that its technical problem that solves the utility model adopts is: a kind of vacuum continuous feeding and discharging device, have cylindrical housings, and run through being provided with charging aperture and discharging opening at the upper and lower side of housing; The central shaft of housing is provided with rotor, is set with rotating vane in the periphery of rotor, forms the storehouse lattice between the adjacent rotating vane; Inwall at housing is provided with sealant.The storehouse lattice that the central shaft rotation drives periphery rotate thereupon, material is entered by charging aperture, fall in the storehouse lattice of charging aperture below, afterwards, end as storehouse lattice left and right sides rotating vane contacts with sealant, make these storehouse lattice form a relatively independent seal cavity, the material in the lattice of storehouse finally arrives the discharging opening of below along with the storehouse lattice change along sealant.In this process, guaranteeing that charging aperture and discharging opening separately in the pressure stability, realized that material is by the continuous transfer of charging aperture to discharging opening.
The making and the installation of sealant for convenience, further: described sealant is divided into the inner walls of charging aperture and discharging opening both sides by the polylith seal assembly semi arch structure that is spliced.
In order to guarantee the sealing property of sealant, further: described seal assembly is made up of sealing block, positioning and fixing piece and briquetting from the inside to the outside successively, the joint face of sealing block and positioning and fixing piece and stationary positioned piece and briquetting is provided with ledge structure, and sealing block is fixed on the positioning and fixing piece.By ledge structure is set on joint face, have bigger contact-making surface when on the one hand sealing block being connected with the positioning and fixing piece, guaranteed the fastness of both combinations, on the other hand, sealing block, positioning and fixing piece and briquetting have also been played the location to positive interaction.
Its anchor ring does not axially leak when guaranteeing that storehouse lattice rotate, and further: the end face at housing is provided with pressure ring, is provided with airtight and watertight padding between pressure ring and the housing.
In order to guarantee to remain good seal clearance between sealant and the rotating vane, can be in smooth and easy the sliding in the outer end that guarantees rotating vane along sealant, assurance has certain air-tightness, further: described housing is provided with pressing plate, offers the Compressed Gas air admission hole on pressing plate.By charging into compressed air to pressing plate inside from the outside by the Compressed Gas air admission hole, compress by the sealant of compressed air the pressing plate below, form the radial floating sealing with rotating vane effectively, the end of sealant and rotating vane is close to, the air-tightness that keeps the storehouse lattice, can give simultaneously sealant certain inside and outside the surplus that collapses, make rotating vane unlikely stuck in rotation process because sealant inwardly shrinks tension.
In order in time to put the pressed gas that runs the storehouse lattice, avoid pressed gas: on housing, also to be provided with the balance gas extraction system outlet that is used to reduce storehouse lattice internal pressure along with the rotation of rotating vane enters the low pressure cavity by high-pressure chamber, further.
Heat or cool off in order to be implemented in material in the lattice of storehouse, further: be provided with the rotor chuck between described rotor and the storehouse lattice, for feeding heating or cooling medium in the rotor chuck.
In order to guarantee the air-tightness between charging and the discharging opening, more further: the quantity of described storehouse lattice is the above odd number lattice of 11 lattice.By the storehouse lattice of some are set, multi-sealed between the cavity of having realized being connected with device charging aperture and discharging opening.In addition, the odd number lattice are set, have further guaranteed the reliability of sealing.
The beneficial effects of the utility model are, when guaranteeing axial seal, can guarantee star rotor low speed rotation convey materials, rely on the rectangular seal piece to be regulated automatically and compress, can form effective radial labyrinth formula sealing again, thereby reduce dynamic and static leakage rate, reached the effect of lock gas, guarantee vacuum and continuous feeding and discharging in the equipment, realized the purpose that continuous vacuum drying is made, the vacuum that can guarantee the airtight Work container that links-0.02～-0.085MPa between.
