Description

A kind of wind screening machine

Technical field

The utility model relates to a kind of refuse treatment plant, more particularly relates to a kind of wind screening machine.

Background technology

The living standard of Along with people's improves gradually; A city of house refuse that is produced in people's daily life will produce the hundreds of ton even go up kiloton every day; If the untimely processing of so many rubbish with the living environment that directly has influence on people, threatens to the healthy of people; For this reason, the various ways of not broken thinking of people are handled rubbish.A main system in the garbage treatment system is a refuse classification; Contain impurity such as a considerable amount of plastics, paper in the organic type material that present separation system sub-elects; Existing equipment can not fully come out this type of separating substances, directly has influence on the efficient of post-processed.That is to say that the problem that existing refuse classification system exists is that the organic type of material purity that sub-elects is not high.

Summary of the invention

In order to overcome the deficiency that exists in the prior art, the utility model provides a kind of wind screening machine that improves organic type of material purity in the refuse classification.

The utility model is realized through following technical scheme: a kind of wind screening machine; Comprise bracing frame and barrel, the last supporting surface of support frame as described above is obliquely installed, and front and back are provided with two rings on the cylindrical of said barrel; The place, following four angles of barrel is provided with roller; One of them roller is connected with motor, and roller is fixed on the last supporting surface of bracing frame, and barrel is placed on the roller through ring; Rear end on supporting surface on the bracing frame is fixed with gear wheel, and the end face of ring contacts behind the cylindrical of gear wheel and the barrel; The barrel of barrel is provided with the open-work that solid matter is uniformly distributed with; On the inner tube wall of barrel stock guide is set; Be provided with hopper below the barrel, the front end of barrel sets into hopper, below the feeding mouth of material bin, is provided with centrifugal blower; The barrel rear portion is provided with the rewinding case, and the outside of barrel is provided with case.

In the such scheme, in order to make material uniformly by moving behind the forward direction, the inner tube wall of said barrel is provided with the stock guide that the upright spiral of many rows distributes.

In the such scheme, the open-work on the said barrel barrel is the small-bore open-work in the front portion of barrel, and the rear portion is the large aperture open-work.

The utility model wind screening machine compared with prior art; Because this wind screening machine is that pneumatic separating and trommelling are organically combined, light type content of material seldom utilizes trommelling earlier less screening substances to be gone out in the general less material; To improve the efficient of selection by winnowing; Utilize wind-force to come out then, thereby reach the purpose of the organic type material of further sorting, improve the purity of organic type of material than the light type sorting substances in the big type material.

Description of drawings

Fig. 1 is the structural representation of the utility model wind screening machine;

Fig. 2 is that A among Fig. 1 is to view.

Among the figure: 1. rewinding case, 2. case, 3. ring, 4. open-work, 5. stock guide, 6. material bin, 7. air inlet, 8. centrifugal blower, 9. roller, 10. motor, supporting surface on 11., 12. bracing frames, 13. gear wheels, 14. barrels, 15. feeding mouths, 16. hoppers.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model wind screening machine is done further to describe:

Fig. 1 is the structural representation of the utility model wind screening machine, Fig. 2 be A among Fig. 1 to view,

Among the figure, this wind screening machine comprises bracing frame 12 and barrel 14, and the last supporting surface 11 of bracing frame 12 is obliquely installed; Barrel 14 is arranged on the bracing frame 12, and an end that is provided with material bin 6 is higher than discharging opening one end, and front and back are respectively arranged with ring 3 on the cylindrical of barrel 14; The following front and back of barrel 14 respectively are provided with two rollers 9, and the roller 9 of one of them front end is connected with motor 10 through reductor, are used to provide the power that roller 9 rotates; Front and rear rolling wheel 9 is fixed on the last supporting surface 11 of bracing frame 12, and barrel 14 is placed on the front and rear rolling wheel 9 through ring 3, when the roller that power is provided 9 rotates; Barrel 14 can rotate under the support of 4 rollers 9; Lower end on supporting surface 11 on the bracing frame 12 also is fixed with two gear wheels 13, and the cylindrical of gear wheel 13 contacts with the end face of the ring 3 of barrel 14 rear ends, plays the role of positioning; Guarantee that barrel 14 does not glide in rotation process, the barrel of barrel 14 is provided with the open-work 4 that solid matter is uniformly distributed with.Stock guide 5 is set on the inner tube wall of barrel 14; Stock guide 5 is multi-detector and distributes on inner tube wall, be provided with hopper 16 below the barrel 14, and the front end of barrel 14 is provided with material bin 6; Below the feeding mouth 15 of material bin 6, be provided with centrifugal blower 8; Barrel 14 rear portions are provided with rewinding case 1, below barrel 14, are provided with hopper 16, and the outside of barrel 14 is provided with case 2.

During work, actuating motor 10, barrel 14 rotates under the rotational support of front and rear rolling wheel 9; Rubbish material is got in the barrels 14 by material bin 6, and centrifugal blower 8 is kept watch and blowed to the rear end of barrel 14, the rubbish material that gets into barrel 14 the continuous rotation of barrel and stock guide 5 constantly stir down by forward direction after mobile; The open-work of less material on inner wall of rotary drum leaks down; Simultaneously, centrifugal blower 8 is sent into high velocity air from air inlet 7, and the light type material in the material is blowed in the rewinding case 1 of barrel 14 rear ends by high velocity air; Isolate light type material, thereby reach the function of the light type material of further classification.

This wind screening machine is that pneumatic separating and trommelling are organically combined, and effectively organic type of sorting substances in the material is come out, and improves the purity of organic type of material.
