Description

The flip-over type screening plant

Technical field

The present invention relates to refuse treatment plant, particularly relate to a kind of flip-over type screening plant that refuse classification is handled.

Background technology

In urban garbage disposal, require as far as possible the utilized thing in the rubbish, as the packing box of plastic foil, polybag, plastics etc. assorted mould to branch away be used, stone, vial, calculon head are sieved out, carry out landfill.

Have the purpose that reaches screening with equipment such as rotary screen, bar screen, circular shale shakers at present, the deficiency of this kind equipment is: the kind of screening is few, big, same treatment effect, the floor space of the volume of equipment, weight is big, the energy consumption height, because of material the motion of screening plant be two-dimentional, treating capacity is little, all can not effectively sieve the light material of spies such as plastic foil, polybag.

Summary of the invention

Based on above-mentioned existing in prior technology problem, embodiment of the present invention provides a kind of flip-over type screening plant, can solve conventional garbage screening field, weights of equipment such as general rotary screen, bar screen, circular shale shaker are big, cost height, the function of production cost and operation maintenance are incomplete, the problem that floor space is big.

The objective of the invention is to be achieved through the following technical solutions:

Embodiment of the present invention provides a kind of flip-over type screening plant, comprising:

Cabinet, at least two sieve plates, drive unit, bent axle and rocking bars; Wherein, diverse location arranges the screening through hole in different apertures on each sieve plate;

Each parts all is arranged in the cabinet; Each sieve plate arranges at interval, each sieve plate one end is arranged on the rocking bar as the preceding strong point, the rear end is arranged on the bent axle by the drive unit driving of the conduct back strong point, the sieve plate that is arranged on rocking bar and the bent axle is preceding high back low dip shape, and each sieve plate can carry out the motion of upper and lower, left and right in the effect of bent axle and rocking bar.

The technical scheme that provides by the embodiment of the invention as can be seen, be obliquely installed by the sieve plate that will have different apertures in the embodiment of the invention, the bent axle that is driven by rocking bar and drive unit supports, thereby under the bent axle effect of rocking bar and drive unit driving, make sieve plate to move upward in each side such as upper and lower, left and right, thereby the rubbish on the sieve plate can be beated at three-dimensional, reach dissimilar rubbish materials are effectively sieved the effect of opening.This screening plant has simple in structure, uses, easy to operate screening efficiency height, plastic foil, the bag material of the sheet that the light and spy that can sieve out easily is light.

The specific embodiment

The invention will be further described below in conjunction with specific embodiment.

Embodiment

Present embodiment provides a kind of flip-over type screening plant, is used for rubbish material is sieved, and shown in Fig. 1～3, this screening plant comprises: cabinet, at least two sieve plates, drive unit, bent axle and rocking bars; Wherein, diverse location arranges the screening through hole in different apertures on each sieve plate, specifically can be that sieve plate is divided into a plurality of sections, different screening through holes is set on every section, as sieve plate being divided into forward and backward two sections, the screening through hole of small-bore is set on the leading portion, wide-aperture screening through hole is set on the back segment; Screening through hole on every section all can be arranged on the sieve plate by the mode that ranks distribute; On the sieve plate taper hock can also be set.

Each parts all is arranged in the cabinet, and cabinet one end is the import of rubbish material, and the other end is the outlet of rubbish material; Each sieve plate parallel interval arranges, each sieve plate one end is arranged on the rocking bar as the preceding strong point, the rear end is arranged on the bent axle by the drive unit driving of the conduct back strong point, the back strong point of each sieve plate is separately positioned on the axle place of respectively turning round of bent axle, the sieve plate that is arranged on rocking bar and the bent axle is preceding high back low dip shape, angle 12～20 degree that tilt (be between sieve plate and the horizontal plane angle be 12～20 degree), each sieve plate can carry out the motion of upper and lower, left and right in the effect of bent axle and rocking bar.

In the reality, above-mentioned flip-over type screening plant can arrange seven sieve plates, bent axle then adopt have seven axles that turn round seven turn bent axle, the back strong point of each sieve plate all is arranged on 7 one of the turning bent axle axle place of turning round.

As shown in Figure 1, when above-mentioned flip-over type screening plant used, the sieve plate 1 that arranges in the cabinet 5 was installed in respectively on bent axle 3 and the rocking bar with certain angle of inclination and order, and bent axle 3 is installed on the cabinet 5, is driven by drive unit 2; Drive unit 2, bent axle 3, sieve plate 1 and rocking bar 4 are formed the crank and rocker mechanism of going up on the lower plane, during sieve plate 1 motion, make the material of sieve plate produce the plane motion of going up on the lower plane; When bent axle 3 rotates, make simultaneously material on the sieve plate 1 produce upper and lower to motion; During screening, will be through coarse crushing or the back domestic waste that becomes thoroughly decomposed, be transported to by belt feeder on the sieve plate 1 of left end (as Fig. 1) of flip-over type screening plant, be distributed with the different screening through hole of pore size and a certain size and taper hock 10 highly on the sieve plate 1 and (see Fig. 3,4), taper hock 10 is a plurality of, can be uniformly set on the sieve plate between the screening through hole, can make light material sieve at sieve plate that layering moves upward in the process by a plurality of taper hocks, and because sieve plate inclination certain angle and form top-down circle and beat, make on the sieve plate 1 material last, down, a left side, the enterprising line bounce screening of right three-dimensional, can sieve out heavy from domestic waste through coarse crushing or after becoming thoroughly decomposed, in, gently, special light four kinds of different specific weights, granularity, (fuel value) material can sieve out short grained heavy material 6 as shown in fig. 1, in particle than heavy material 7, oarse-grained light material 8, special light 4 kinds of different materials such as material 9 grades of large stretch of grain.

In sum, the flip-over type screening plant of the embodiment of the invention, can carry out the flip-over type screening at three-dimensional to rubbish material, easily coarse crushing or the back domestic waste that becomes thoroughly decomposed are sieved into heavy, in, the material of light, special light four kinds of different specific weights, granularity, (fuel value), made things convenient for subsequent treatment, this screening plant is simple in structure, easy to operate, screening efficiency is high, and operating cost is low.Problems such as it is big to have solved weights of equipment such as existing general rotary screen, bar screen, circular shale shaker, and cost height, the function of production cost and operation maintenance are incomplete, and floor space is big.

The above; only for the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
