Description
Technical field
The present invention relates to the sorting of house refuse, be specifically related to a kind of polygonal sieve cylinder and the polygonal rotary screen extension set of house refuse with this cylinder.
Background technology
Granted publication number is called " difunctional thick, thin material rotary screen " for the Chinese utility model patent of CN 2129177Y discloses a kind of utility model name.Illustrated in figures 1 and 2 like it, the screen drum frame fixation of this rotary screen is circle in circular guideway, and circular guideway is supported on the support roller; Support roller is by bracket supports, and screen drum is by the gear wheel axial restraint, and screen drum is equipped with gear ring outward; By gear drive, also can lean on support roller and circular guideway friction transferring power by the support roller transferring power; Material gets into screen drum by charging aperture, and oversize falls within belt conveyor by discharging opening, and screenings falls within belt conveyor.The screen drum cross section is a regular polygon, and accompanying drawing is depicted as octagon, each hinged inside one removable cover of its seamed edge; The removable cover edges of boards all can be placed on each limit mid point, and each limit screen cloth is demarcated with mid point, and one is the scalping plate; One is thin sieve plate, and the space rearranges sieve nest, and the hole of sieve plate is kidney shape hole.This rotary screen is because its circular guideway is an annular, and the screen drum frame fixation is circle in circular guideway, and the screen drum cross section is a regular polygon; This is being just polygon become circle in this in connect regular polygon; Like this, the technical scheme of the present invention that below having, will describe is compared, under the identical situation of the excircle dimension of guide rail; The cross-sectional area of the screen drum of its regular polygon is little, and the amount of unit interval sorting house refuse is few.
Summary of the invention
The present invention will provide a kind of improved polygonal sieve cylinder.
Improved polygonal sieve cylinder of the present invention; Comprise a feed end rolling ring (110), a discharge end rolling ring (120), a screen drum (130), a feeding cylinder (140) and a discharge barrel (150); It is characterized in that this feed end rolling ring (110) is identical with this discharge end rolling ring (120) structure, is annular solid; Its outer surface is circular; Inner surface is a polygonal, and this screen drum (130) is and the corresponding polygonal of this polygonal of this inner surface of this feed end rolling ring (110) and this discharge end rolling ring (120) that the two ends of this screen drum (130) are fixedly connected with each corresponding side of this discharge end rolling ring (120) with this feed end rolling ring (110); One end of this feeding cylinder (140) is fixedly connected with the another side of this feed end rolling ring (110), and an end of this discharge barrel (150) is fixedly connected with the another side of this discharge end rolling ring (120).
Because the feed end rolling ring (110) of improved polygonal sieve cylinder of the present invention (100) and the inner surface of discharge end rolling ring (120) are polygonal; Screen drum (130) is the corresponding polygonal of polygonal with the inner surface of feed end rolling ring (110) and discharge end rolling ring (120); The two ends of screen drum (130) are fixedly connected with each corresponding side of feed end rolling ring (110) and discharge end rolling ring (120); The another side of one end of feeding cylinder (140) and feed end rolling ring (110) is welded to connect; The another side of one end of discharge barrel (150) and discharge end rolling ring (120) is welded to connect; The polygonal sieve cylinder (100) that constitutes like this; Compare with screen drum frame fixation round polygonal sieve cylinder in circular guideway (being equivalent to feed end rolling ring of the present invention (110) and discharge end rolling ring (120)) of prior art; Under the interior circle or the essentially identical situation of inner surface size of guide rail (being equivalent to feed end rolling ring of the present invention (110) and discharge end rolling ring (120)), the cross-sectional area of screen drum of the present invention (130) is big, and the amount of unit interval sorting house refuse is many.
Valuably; This screen drum (130) is made up of a screen frame (unit) (131) and polylith sieve plate (132); This polylith sieve plate (132) is installed on a plurality of screen frames (1314) of this screen frame (unit) (131), and every this sieve plate (132) is positioned at the corresponding plane at this feed end rolling ring (110) and this discharge end rolling ring (120) polygonal inner surface place from the nearest surface of this screen drum (130) center line.
Like this, house refuse is in the process that moves through feed end rolling ring (110), screen drum (130) and discharge end rolling ring (120), and institute is level and smooth through the path, can not stop and is detained because of receiving.
Valuably; This screen frame (unit) (131) has many to longitudinal angle girder steel (1311) and many to lateral angle girder steel (1312); Two angle beams of every pair of this longitudinal angle girder steel (1311) are oppositely arranged; Connect a pair of relative side weld of these two angle beams continuous through vertical polylith connecting plate (1313) spaced apart; Another equates these two angle beams the angle between two intersection surface of the angle between the relative limit and this feed end rolling ring (110) and this discharge end rolling ring (120) polygonal inner surface; The two ends of many every pair of these longitudinal angle girder steels (1311) to this longitudinal angle girder steel (1311) are weldingly connected with this feed end rolling ring (110) and each corresponding side of this discharge end rolling ring (120) respectively, the top of the corresponding angle of welding position between two intersection surface of this feed end rolling ring (110) and this discharge end rolling ring (120) polygonal inner surface, and two angle beams of every pair of this lateral angle girder steel (1312) are oppositely arranged; A pair of relative limit is adjacent to each other; Spot welding connects, and how vertically spaced apart to this lateral angle girder steel (1312), the two ends of every pair of this lateral angle girder steel (1312) are weldingly connected with two adjacent these longitudinal angle girder steels (1311) respectively.
Like this, only continuous manyly just can constitute screen frame (unit) (131) to longitudinal angle girder steel (1311) and many to lateral angle girder steel (1312) through being welded to each other, simple in structure.
Valuably; This feeding cylinder (140) is made up of a cylinder (141), an annulus end plate (142) and polylith scraping wings (143); This polylith scraping wings (143) circumferencial direction separate and with the angled inner surface that is welded to connect in this cylinder (141) of the center line of this cylinder (141); This annulus end plate (142) is welded to connect the end at this cylinder (141); The other end of this cylinder (141) is welded on the another side of this feed end rolling ring (110), and the circle that the orthographic projection of the inner surface of this cylinder (141) forms becomes the polygonal circumscribed circle of the orthographic projection formation of this feed end rolling ring (110) inner surface.
Like this, be welded to connect polylith through inner surface and separate and the scraping wings (143) angled, can the house refuse that fall into feeding cylinder (140) be pushed screen drum (130) smoothly with the center line of cylinder (141) at circumferencial direction at cylinder (141); End through at cylinder (141) is welded to connect, and can prevent that the house refuse that falls into feeding cylinder (140) from dropping to feeding cylinder (140) outside; The circle that the orthographic projection of the inner surface of cylinder (141) forms becomes the polygonal circumscribed circle of the orthographic projection formation of this feed end rolling ring (110) inner surface; Guaranteeing that the house refuse that falls into feeding cylinder (140) is getting under the situation of screen drum (130) under the promotion of scraping wings (143) smoothly, can reduce the diameter of feeding cylinder (140) to greatest extent.
