Summary of the invention
The invention provides the device that a kind of composting carries out even feeding, screening.Selecting type screening rubbish charging gear provided by the invention and method have the characteristics such as large part material screens, charge efficiency is high, feed is even, convenient operation management.
Selecting type screening rubbish charging gear involved in the present invention is comprised of large part material collection storehouse (1), large part material screening cylinder (2), large part material screening drum drive motor (3), moving grid (4), the grid that fix (5), large part material slide carriage (6), crank drive motors (7), collecting tank (8), crank (9), normal material feed opening (10), frame (11).Large part material collection storehouse (1) has 2, is arranged in head and tail; Crank (9) has 4, and 1 is driving crank, is driven by crank drive motors (7), and all the other 3 is driven crank, is installed on the moving grid.See the schematic diagram of accompanying drawing 1 selecting type screening rubbish charging gear and method.
Embodiment
The selecting type screening rubbish feeding method that the present invention relates to is mainly realized by following steps.
Seeing that 2, two large part material slide carriages of accompanying drawing vertically are arranged symmetrically in equipment longitudinal centre line both sides, is 3 charging planes with grid charging plane longitudinal subdivision.Material laterally or longitudinal size greater than be considered as " the large part material " of regulation material size, when large part material was laterally upper across large part material slide carriage (6), material dropped down onto in the large part material collection storehouse (1) owing to Action of Gravity Field will glide from the clinoplain that slide carriage forms; When large part material when slide carriage vertically falls into charging aperture, material can the stepping of servo-actuated grid (4) periodicity be delivered to feed opening, be provided with large part material screening cylinder (2) at the feed opening place, large part material screening cylinder (2) is driven by large part material screening drum drive motor (3) and does circular-rotation, be equivalent to the short distance belt conveyor, greater than the material of " large part material width " since longitudinal length greater than the width of normal material feed opening, material will stride across large part material screening cylinder (2) and fall to large part material collection storehouse (1) under the progradation of moving grid (4).
The motion prototype of moving grid (4) is Planar Crank-and-rocker Mechanism, see accompanying drawing 3; rocking arm is equivalent to the moving grid (4) of equipment; driving crank is equivalent to the crank (9) that equipment crank drive motors (7) drives; driving crank is to do counterclockwise circular motion under crank drive motors (7) drives at prime mover, and rocking arm i.e. moving grid (4) is done periodic wobble.Circular motion drive rocking bar by crank is done the bottom right to upper left oscillating motion, reaches with this to make the periodically stepping lifting feeding of material type.For ensureing the complete and reliable of discharging, moving grid (4), the grid that fix (5) all adopt the circular arc discharging structure at discharge side, reach the discharging requirement.After normal material entered grille plane, crank (9) was done the counterclockwise circular motion in plane by motor-driven, and moving grid (4) is done cycle rocking arm motion under crank (9) effect.
The lifting of material and propelling are referring to accompanying drawing 4, in original state, bank is put on the grid that fix (5), the material lifting of moving grid (4) on the grid (5) that will fix under crank (9) driving, and begin to move to the upper left side, when crank (9) turns over 180 ° counterclockwise, material falls after rise to the grid that fix (2), at this moment, 1 unit distance of material lifting moves forward 1 unit distance.Crank (9) is rotated further, rotate 360 ° get back to original position after, finish the material discharging at top at moving grid (4), the grid that fix (5) top arc discharge pit by the staggered action of two grids, material enters normal material discharge port (6); Begin the action of for the second time stepping feed in original position simultaneously.
Moving grid (4), the grid that fix (5) are made by elongate rod, two grid interlaced arrangement, and in the staggered step motion process of grid, the grid face is that elongated hole is netted, has the function of filtration, the liquid in the material is filtered off through grid and is collected in the collecting tank (8); The simultaneously crisscross motion between grid is conducive to clean the tamper between grid.
Selecting type screening rubbish charging gear provided by the invention and method have following obvious superiority.
(1) the present invention can selectively carry out the transmission of composting, avoids all materials all to enter next flow process.
(2) the present invention can effectively remove liquid in the composting, thereby reduces the humidity of rubbish, is convenient to follow-up separation etc.
(3) conveying capacity of the present invention is strong, do not twine, wear-resistant, do not stop up.
