Abstract

The utility model provides a reverse return product air classification device, comprising an aspirator, the bottom of which is provided with an outlet, a feeding device, a blower and a setting pocket, wherein, the discharge end of the feeding device stretches into the aspirator horizontally, and the air outlet of the blower stretches into the aspirator in the direction of tangential horizon, and is arranged under the discharge end of the feeding device, the bottom of the setting pocket is provided with a discharging port, and the utility model is characterized in that a sealing channel is added between and communicated with the aspirator and the setting pocket, the bottom of the sealing channel is blocked by a conveyer belt on the upper end of a belt conveying device, the conveying surface of the belt conveying device is lower than the air outlet of the blower, the conveying direction is opposite to the air classification direction, and the exhaust end of the utility model is arranged inside the aspirator. Because the sealing channel is added between and communicated with the aspirator and the setting pocket, the bottom of which is blocked by the belt conveying device, the conveying direction of which is opposite to the air classification direction, in this way, no broken trash can be returned to be broken again on the basis of air classification, the classification quality of trash can be greatly improved when the trash is classified by air after being broken.

Description

Reverse returning charge pneumatic separation device

Affiliated technical field

The utility model provides a kind of reverse returning charge pneumatic separation device, belongs to the rubbish air blasting device technical field.

Background technology

Development along with society, rubbish also more and more becomes a great problem of environmental pollution, sorting, the recovery of paying attention to rubbish have become the problem that each city must be faced, refuse classification is also from the past flammable and non-flammable classification, the stationery of progressive segmentation up till now, category of glass, metal species, plastics class etc.Though the technology and the equipment of at present existing rubbish air blasting classification owing to the various rubbish that are intertwined in the raw refuse can not be separated, are rolled in the polybag as weight package, so the effect of selection by winnowing is unsatisfactory, its function awaits further to improve.

The utility model content

The purpose of this utility model provides and a kind ofly can overcome that above-mentioned defective, refuse classification are more thorough, the reverse returning charge pneumatic separation device of function admirable.Its technical scheme is:

Comprise that the bottom is provided with the air classifier of discharging opening, feed arrangement, blower fan and expansion chamber, wherein the discharge end level of feed arrangement stretches in the air classifier, the tangential level of the air outlet of blower fan stretches in the air classifier, and be positioned at the below of the discharge end of feed arrangement, the bottom of expansion chamber is provided with discharging opening, it is characterized in that: the seal channel of between air classifier and expansion chamber, setting up a UNICOM, the bottom shutoff of seal channel is to be positioned at the conveyer belt of upper end in the belt conveyor, and the conveyor surface of belt conveyor is lower than the air outlet of blower fan, its transporting direction is opposite with the selection by winnowing direction, and its exhaust end is positioned at air classifier.

Described reverse returning charge pneumatic separation device, feed arrangement adopts belt conveyor.

Described reverse returning charge pneumatic separation device, seal channel be along being provided with flow guide bar on belt throughput direction, the sidewall in contiguous belt conveyor above the conveyor surface, all drops on the conveyer belt at the rubbish that seal channel falls guaranteeing.

Described reverse returning charge pneumatic separation device, the bottom of expansion chamber is evenly equipped with two discharging openings along the selection by winnowing direction, and its sidewall that is not less than the fan outlet level is provided with sharp-pointed broken projection, is used for the broken once more of rubbish.

Operation principle is: rubbish is in discharge end is sent into air classifier, the discharging opening that can not just be provided with from the air classifier bottom by the block rubbish that wind is moved falls naturally and selects, resemble polybag, the rubbish that paper etc. are light will pass seal channel and directly enter expansion chamber under the blowing of blower fan, different discharging openings by expansion chamber are discharged collection, lighter slightly rubbish or resemble light, heavy snarly rubbish, as wrapping weight in the polybag, under the blowing of blower fan, can drop on the belt conveyor in the seal channel, because the transporting direction of belt conveyor is opposite with the selection by winnowing direction, so this part rubbish can be transported back in the air classifier again, the discharging opening that is provided with from the air classifier bottom falls naturally and selects, through repeating above-mentioned selection by winnowing program again after the fragmentation once more.

The utility model compared with prior art, owing to set up the seal channel between UNICOM's air classifier and the expansion chamber, and the bottom shutoff is with the transporting direction belt conveyor opposite with the selection by winnowing direction, there is not broken rubbish can on the basis of selection by winnowing, return fragmentation once more like this, treat brokenly to carry out again subsequently selection by winnowing, avoided that refuse breaking is insufficient, the halfway defective of selection by winnowing, improved the quality of happy refuse classification, excellent working performance.
