Description

Unloader dust collector

Technical field

The utility model relates to environmental protection and improves the device of labor protection of dust working environment.

Background technology

Current terminal loading and unloading system operation process is open mostly, will inevitably produce a large amount of dust in handling material process.Dust has very large impact to human body, product design, operating environment etc.

In order to dedusting, some unloader just fills on hopper that some are simple, resemble adopt waste and old belt surround tripartite (extra large side is not enclosed, side, land in order to have by ship storehouse scavenging machine make movable), but it is more difficult to surround top.Even if having employed to enclose and block device, to discharging produce surge air-flow also cannot absorb, and enclose block the whipping of thing when air-flow springs up with grab bucket discharging time roar together with sympathetic response, produce very large noise.

Some is in order to reduce the pollution of dust, and adopt traditional spray dedusting technology, the drop diameter 200-300 μm of generation, not only efficiency low energy consumption is high, and often causes material too moistening, affects end product quality and makes coal calorific value produce loss.

In the last few years along with the progress of science and technology, have employed dry fog room pattern and carry out dedusting, with the sealing of polyethylene Air Filter is an example.Arrange that several rows of Dry-fog spray nozzle forms dust-proof wall again in the inner side by net, in a row spray downwards on facade, transverse jet in a row on end face, the diameter 1 meter of the mist of each nozzle ejection, length reaches 4 ~ 6 meters.This method makes dedusting constitute Double-protection, forms the mist wall of sealing during spraying, and mist wall also has one deck Air Filter outward.The effect surrounding dust is in theory fine, but make dry fog spray dust-proof wall desirable as above, dry fog post need be grown to be needed slightly, particularly want dry fog to spray reach 6 meters, pressurized air must be made at a high speed by the transition pod apertures of nozzle, under the air velocity of superelevation, also need the pressure of superelevation, just can make dry fog column length and thick, this makes power supply somewhat excessive, such that the other shortcoming of equipment is as easy to wear in nozzle, air feed equipment requires that the shortcoming such as high appears too much.

Utility model content

The technical problems to be solved in the utility model builds clean power plant, the coal dust produced when removing coal jetty's discharging, there is provided a kind of keep off most dust and suitably can reduce again the high pressure needed for the generation of usual dry fog, high air velocity, thus the device reducing dusting equipment cost.

For solving the problems of the technologies described above, this device builds semiclosed discharging dust collecting space on the hopper of unloader.

Unloader dust collector, the hopper of unloader is built protection steel structure and on the left and right wall of protection steel structure, polyethylene Air Filter and nozzle seat board is installed respectively, the upper end of left and right wall is separately installed with rotating lid door and jacking apparatus, the side, land of left and right wall is provided with fixedly goes along with sb. to guard him and movable lifting overhang-door, handling passage is made when overhang-door puts down, in 18 degree of inclinations after two lid door closures close, 2 ~ 3 meters of gaps are left at top after two lid door closures close, side, sea is provided with fixedly protect identical with the width that side, land is fixedly gone along with sb. to guard him and blocks, to facilitate grab bucket turnover operation.

The false air coefficient of above-mentioned polyethylene Air Filter is 30%, and the coal ash flown upward surge blocks the dust of 70%, and the surge air-flow that material produces to the shock wave of hopper is absorbed by the Air Filter of breathing freely.

These nozzle holders on four pieces or six pieces of aluminum nozzle holders, then are discharged to the both sides of grab bucket discharging place by the pipeline centralized arrangement of said nozzle seat board, and to aim at a dirt pits near-distance supply dry fog of grab bucket discharging, dry fog has been blowed to dirt pits by nozzle holder place low-pressure air.

Be furnished with many pipelines in above-mentioned nozzle holder, pipeline enclosure have can lead in press wind to ventilate air channel, adapter shaft flow fan hermetically after nozzle holder, nozzle holder is provided with nozzle, and the effect that dry fog is propelled is not only evenly but also have certain pressure.

Above-mentioned polyethylene Air Filter internally plays isolation external influence, dry fog and the air-flow of coal dust with vortex in netting are drifted about in an orderly manner, continues together to be atomized with the dry fog that nozzle holder sprays continually and sink or adhere at basket strainer place playing the fraction coal dust that is not also atomized of dirt pits.

Four pieces or six pieces of nozzle holder centralized arrangement play dirt pits towards grab bucket discharging.The dry fog of ejection improves the collisional mixing effect with surge coal dust under the promotion of low-pressure air, the straight air stream that surge coal dust air-flow and dry fog spray forms eddy airstream effectively, along with the vortex motion of coal dust, drive again the eddy current scrolling of dry fog, in scrolling process, accelerate both collisions, mixing, make the increase of coal dust volume, gravity decline.

Be separated from the coal dust of vortex motion, drift about disorderly in Air Filter with dry fog, along with dry fog is sent by light breeze continuously, discharging later stage dry fog concentration in net is greater than Dust Concentration rapidly, continues to be mixed by dry fog, increase the weight of, decline to cause most of coal dust.Some special light coal dusts with together with the dry fog waved blocked by net at Air Filter place, or decline or adhere to online.The coal dust so flown out outside net is very little already.

Dry fog large for dust portion is removed in dirt pits, make the non-close mouth in extra large side, land upper lateral part estuary and top cover door gap dehisce allow completely.

When boats and ships need cabin cleaning machinery, side, land overhang-door is put into the material collecting tank place of about one meter, below hopper plane, two fan lid door jack-up are so that cabin cleaning machinery passes through simultaneously.

Present people are further strong to the serious hope of blue sky clear water, this dust collector adopts the covering of polyethylene Air Filter, employing nozzle holder is concentrated and pressed Wind Volume blower fan propelling movement dry fog effectively to form eddy current in playing a dirt pits ejection dry fog, adopting, and design like this makes dust removing effects even more ideal.
