Abstract
The invention discloses a cylindrical duplex screen for feed. The cylindrical duplex screen comprises a motor, a speed reducer, a roller device, a rack, sealing covers, a feeding port and a discharging port. The cylindrical duplex screen is characterized in that the roller device comprises an outer-layer roller screen and an inner-layer roller screen. The inner-layer roller screen is installed on the inner side of the outer-layer roller screen. A plurality of supporting bars are welded between the outer side of the inner-layer roller screen and the inner side of the outer-layer roller screen. The motor is connected with the speed reducer. The speed reducer is connected with the roller device. The roller device is arranged on the inner side of the rack. The sealing covers are installed on the periphery of the rack. The feeding port is formed in the upper side of the rack, and the discharging port is formed in the lower side of the rack. The double layers of roller screens are adopted for the cylindrical duplex screen for feed; the raw material cleaning screen for cleaning a material three times is achieved; a single-roller cleaning screen in the prior art is improved, and the defect of screening large objects and not screening small objects is overcome; cleaning of large impurities of raw materials and cleaning of small impurities of raw materials can be achieved through one machine, and the screening purity is high; complete machine demounting is adopted for the roller device, and maintenance is fast and effortless.
Description
Technical field
The invention belongs to feed production equipment technical field, be specifically related to the compound sieve of a kind of feed cylinder.
Background technology
Drum apparatus tilts to be installed in frame; Motor is linked together by shaft coupling through reductor and drum apparatus, and head roll device rotates around its axis; After material enters drum apparatus, due to inclination and the rotation of drum apparatus, make the materials overturning on compass screen surface and rolling, the discharging opening of qualified material (undersize) bottom cylinder rear end is discharged, and underproof material (oversize) is discharged through the discharge gate of cylinder afterbody; Due to the upset of material in cylinder, rolling, the material be stuck in sieve aperture can be ejected, prevent sieve pore blockade; Roller sand screener, cylinder round sifter are almost identical with the principles of construction of rotary screen, are that people there are differences on its understanding and call.Existing cleaning sieve is generally monotubular structure, there is sieve and very much not sieves little disadvantage, is difficult to effective separation energy and effectively isolates that straw, masonry, fag end, branch, corncob etc. are greatly assorted and earth, the not plump paddy of sand grains etc. are little assorted.
Summary of the invention
one) technical problem that will solve
For solving the problem, the present invention proposes the compound sieve of a kind of feed cylinder, the disadvantage of monotubular cleaning sieve can be improved; Assorted, the little greatly assorted machine cleaning of raw material can be realized.
(2) technical scheme
The compound sieve of a kind of feed cylinder of the present invention, comprises motor, reductor, drum apparatus, frame, seal cover, charging aperture and discharging opening composition; It is characterized in that: described drum apparatus comprises outer rotary screen and internal layer rotary screen; Described internal layer rotary screen is installed on inside outer rotary screen; Many support bars are welded with between outside described internal layer rotary screen and inside outer rotary screen; Described motor connects reductor; Described reductor connects drum apparatus; Described drum apparatus is installed on inside frame; Described frame surrounding is provided with seal cover; Described charging aperture and discharging opening are installed on the upper and lower sides of frame respectively.
Further, described reductor coordinates with internal layer rotary screen and installs.
Further, described discharging opening is respectively little assorted interface, raw material interface and assorted greatly interface.
Further, described little assorted interface is near reductor side.
Further, described outer rotary screen and internal layer rotary screen are made up of woven wire cloth or punched steel plate, and cylindrical shell rotates around the axle of trunnion axis or slightly inclination.
(3) beneficial effect
Compared with prior art, it has following beneficial effect in the present invention: adopt double-deck screen drum; Achieve the raw material handling sieve that a thing three is clear; Improve monotubular of the prior art cleaning sieve, sieve very much not sieves little disadvantage; Can realize assorted, the little greatly assorted machine cleaning of raw material, well sifted degree is high; Drum apparatus adopts complete machine handling, maintenance convenient power-saving.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention;
Fig. 2 is drum apparatus structural representation of the present invention.
Detailed description of the invention
Embodiment 1:
As depicted in figs. 1 and 2, the compound sieve of a kind of feed cylinder of the present invention; Comprise motor, reductor 1, drum apparatus 2, frame 3, seal cover 4, charging aperture 5 and discharging opening 6 to form; Described drum apparatus 2 comprises outer rotary screen 7 and internal layer rotary screen 8; Described internal layer rotary screen 8 is installed on inside outer rotary screen 7; Many support bars 9 are welded with between outside described internal layer rotary screen 8 and inside outer rotary screen 7; Described motor connects reductor 1; Described reductor 1 connects drum apparatus 2; Described drum apparatus 2 is installed on inside frame 3; Described frame 3 surrounding is provided with seal cover 4; Described charging aperture 5 and discharging opening 6 are installed on the upper and lower sides of frame 3 respectively.
Wherein, described reductor 1 coordinates with internal layer rotary screen 8 and installs; Described discharging opening 6 is respectively little assorted interface 6a, raw material interface 6c and large assorted interface 6b; Described little assorted interface 6a is near reductor 1 side; Described outer rotary screen 7 and internal layer rotary screen 8 are made up of woven wire cloth or punched steel plate, and cylindrical shell rotates around the axle of trunnion axis or slightly inclination.
The compound sieve of a kind of feed cylinder of the present invention; Adopt double-deck screen drum; Achieve the raw material handling sieve that a thing three is clear; Improve monotubular of the prior art cleaning sieve sieve and very much not sieve little disadvantage, effectively can isolate that straw, masonry, fag end, branch, corncob etc. are greatly assorted and earth, the not plump paddy of sand grains etc. are little assorted; Be widely used in provision store, stand and Feed Manufacturing department, in raw grain production scene, face to face impurity elimination, thus thoroughly solve raw grain adulteration problem, ensure that and reach safe storage standard by the degree of purity that raw grain is purchased.Meanwhile, this sieve is also used in powder process, husk rice, feed, grease, seed, brewery, storehouse silos make raw material handling equipment.
Embodiment recited above is only be described the preferred embodiment of the present invention, not limits the spirit and scope of the present invention.Under the prerequisite not departing from design concept of the present invention; the various modification that this area ordinary person makes technical scheme of the present invention and improvement; all should drop into protection scope of the present invention, the technology contents of request protection of the present invention, all records in detail in the claims.
