Abstract
The invention discloses a rotary screening machine which is used for grading materials according to particle sizes. The rotary screening machine mainly comprises a machine frame, a screen frame, a screen net, a feeding pipe, a gear motor and a central shaft, wherein the screen net can rotate with the central shaft. The rotary screening machine is mainly characterized in that a feeding screw is placed inside the feeding pipe, screen barrel spoilers are placed on a section, locating inside the screen net, of the central shaft, and both the feeding screw and the central shaft are driven by the gear motor. The screen barrel spoilers face towards the direction of the feeding pipe and are slantly and sequentially installed on the central shaft from top to bottom in a stagger mode. When the feeding screw rotates, the materials are continuously delivered into the screen net along the direction of screwing, and the materials do axial motion and at the same time rotate around the central shaft inside the screen net with the screen barrel spoilers. The rotary screening machine is large in screening energy and screened materials are even. The rotary screening machine is simple and compact in structure and small in floor space.

Description of drawings
Fig. 1 is the structural representation of a specific embodiment of rotary screen extension set of the present invention.
The specific embodiment
Introduce in detail the preferred embodiments of the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, this rotary screen extension set is used for material is carried out classification by granular size, comprises be used to the frame 80 that supports whole apparatus, is installed on the screen frame 10 that is used for preventing flour dust overflow on frame, is located at the screen cloth 20 in screen frame 10; Screen cloth 20 is arranged on screen cloth support 201, and screen cloth 20 front ends are connected with feed pipe 40, and the sidewall of feed pipe 40 is provided with charging aperture 402, and material is in feed pipe 40 is transported to screen cloth 20; Reducing motor 70 also is installed on frame 80, the clutch end of reducing motor 70 is connected with central shaft 30, central shaft 30 passes the inner and feed pipe of screen cloth 20 40 inside, the two ends of central shaft 30 are equipped with the bearing block 301 of fixed function, thus screen cloth support 201 be fixedly connected with central shaft 30 make screen cloth 20 can with central shaft 30 rotation make material in screen cloth 20 according to the granular size classification.Be provided with feeding spiro rod 401 in feed pipe 40, preferred, screw rod 401 can be comprised of the spiral lamellar body that is the helical curve path, makes material along the helical curve delivery pathways, and feeding spiro rod 401 is also driven by reducing motor 70, and central shaft 30 passes feeding spiro rod 401.Central shaft 30 is provided with screen drum spoiler 202 in the part that is positioned at screen cloth 20 inside, and screen drum spoiler 202 can make material rotate in screen cloth 20.The bottom of screen frame 10 is provided with particulate discharge bucket 50, and the entrance of particulate discharge bucket 50 faces toward the wire side of screen cloth 20 to collect the less material of isolated particle from screen cloth 20; The bottom of institute's screen frame also is provided with large grain discharge bucket 60, and large grain discharge bucket 60 is positioned at particulate discharge bucket 50 away from a side of feed pipe 40, to collect from the larger particle of particle of screen cloth 20 rear ends discharges.
When material is entered in feed pipe 40 by charging aperture 402, feeding spiro rod 401 under the driving of reducing motor 70, with mass transport to screen cloth 20.Owing to having adopted applied power to make the material particles motion, therefore do not need the material air blast is not had the danger of obstruction yet, and conveying capacity is large, course of conveying is stable.Because screen cloth support 201 is fixedly connected with central shaft 30, under the effect of reducing motor 70, screen cloth 20 can be with central shaft 30 rotations, and the material that is delivered in screen cloth 20 can be along with screen cloth 20 axial-rotation together.Because central shaft 30 is provided with screen drum spoiler 202 in the part that is positioned at screen cloth 20 inside, screen drum spoiler 202 also can be with central shaft 30 rotations, and material is under the effect of screen drum spoiler 202, except axially-movable, also can rotate, so material screening is more even, the screening energy is larger.Material is separated to screen cloth 20 rear ends from screen cloth 20 front ends, and fines is discharged from screen cloth 20 front end bottoms, is collected in fines discharge bucket 50; Coarse fodder is collected in coarse fodder fines discharge bucket 60 from screen cloth 20 rear ends discharges.Because whole screening process carries out, therefore can not produce dust pollution in the screen frame 10 of sealing.For different materials, can realize best screening effect by the power of controlling reducing motor 70.
Preferably, the two ends in sieve chamber 10 also are provided with first sieve chamber lid the 101 and second sieve chamber lid 102, to cover sieve chamber 10, avoid material and dust to fly away out, and can dismantle easily and clear up screen cloth 20.
Preferably, screen drum spoiler 202 is the interlaced setting in up and down successively on described central shaft, can increase material and the chance that screen drum spoiler 202 contacts, and makes material screening more even.
Preferably, screen drum spoiler 202 tilts to be installed on central shaft towards the direction of feed pipe 40, and material can produce little whirlpool in axially-movable, and material screening is more even.
Preferably, the part that central shaft 30 is positioned at sieve chamber 10 establishes to overlap axle sleeve 303, and axle sleeve 303 is provided with screen cloth alignment pin 304, and screen cloth alignment pin 304 is positioned at the outside of screen cloth 20 rear ends, further the fixing also position of capable of regulating screen cloth 20, prevent that screen cloth 20 from departing from rotary course.
Preferably, bearing block 301 hermetic seals at central shaft 30 two ends prevent that tiny dust from entering bearing block 301, make central shaft 30 stuck.
Preferably, screen cloth 20 can be made into horn-like, and its mesh size increases from front to back gradually, better different big or small material particles are carried out classification.
Above-mentioned rotary screen extension set relates to the monitoring of support that bearing block, suitable position should use or bearing, reducing motor etc. prior art not to be described, and should use suitable prior art to realize the basic function of this rotary screen extension set.
Above-mentioned rotary screen extension set is due to the design of having adopted feeding spiro rod and screen drum spoiler to cooperatively interact, so charging can be faster more stable, and material screening is more even, the screening energy is larger.Screening process carries out in the screen frame of sealing, can not produce dust pollution.And whole rotary screen extension set is simple and compact for structure, and floor space is little, and energy consumption is low.
Above disclosed is only preferred embodiment of the present invention, certainly can not limit with this interest field of the present invention, and the equivalent variations of therefore doing according to the present patent application the scope of the claims still belongs to the scope that the present invention is contained.
