Description
Technical field
The invention belongs to field of garbage disposal, and in particular to a kind of improvement drum sieve finely sieved for aging rubbish and
Its processing method.
Background technology
China gradually starts to dispose as urban garbage disposal using land-fill method since the 1970s
Method.But with the annual increase of quantity of refuse, and a large amount of refuse landfills or are i.e. up to saturation state so that anxious
Contradiction between the quantity of refuse that speed increases and land resource is increasingly prominent out.Therefore the aging life to refuse landfill is needed
Rubbish is handled, and refuse landfill landfill space is changed to rise.
Dystopy resettlement, improvement two ways in situ are mainly used for the processing of mineral and municipal waste at present.In view of aging
The environment of rubbish influences, and most household refuse landfill sites integrated treatments disposes skill in screening strange land in situ using storage rubbish
Art.Since the land-fill method of rubbish is mainly clay and rubbish layering landfill, many clays are adulterated in screening process, with
The higher soil of a kind of ratio of viscosities that organic matter after rotting is formed, what screening in situ was usually handled in addition is the larger object of humidity
Material, it is difficult to short time dehydration, therefore under the action of conveyer belt easily dough is formed with rubbish, it is difficult to it separates.
Invention content
To overcome above-mentioned technical problem, water content is reduced using the aging rubbish of hot air the present invention provides a kind of
The device and its processing method that mineral and municipal waste finely sieves.
In order to achieve the above objectives, the present invention is achieved by the following technical solutions.
A kind of device that mineral and municipal waste finely sieves, including improve roller, cylinder seal closure, charging cover, discharge cover,
Hot gas flow tube, driving device；The improvement roller is tilted-putted shaftless punching drum sieve, and the both ends for improving roller are set respectively
There are first charging aperture and the first discharge port, and first charging aperture is higher than the first discharge port；The driving device is located at described change
It is rolled into the lower part of roller to driving drum；The improvement inner wall of rotary drum is equipped with the material dispersion protrusion of rule distribution；Into
Material cover and discharge cover are respectively provided at the both ends of seal closure, and roller is sealed, set on charging cover by seal closure and charging cover, discharge cover
There is the second charging aperture communicated with first charging aperture, the second discharge port communicated with the first discharge port is equipped in discharge cover；Heat
One end of gas flow tube passes through seal closure, and the inclined slightly upwards feed zone being arranged in improvement roller of opening at the end；Positioned at changing
Tail gas gas gathering mask is set at the top of into the seal closure at the discharging section of roller；The external solid chemicals of second charging aperture add hopper.It is old
Rotten rubbish is reduced after entering drum sieve by hot air, water content, and fertile soil declines with the viscosity of inorganic aggregates and light materials,
And disperse under the shock of protrusion to spread out in drum sieve, fertile soil is sifted out by sieve pore, and inorganic aggregates and light materials edge are inclined
Oblique roller discharges from rear end.
Further, the improvement roller is improved shaftless rotary screen, is equipped with according to rule in the drums inside of punching
The material dispersion protrusion of arrangement；The Circularhole diameter of the rotary screen distribution is 5 ~ 10mm, and the material dispersion protrusion is slanting
Triangular pyramid, height of projection is in 30 ~ 50mm；The arrangement regulation is on the circumference in the same section of drum sieve and two neighboring
Disperse protrusion inclined direction on the contrary, and roller gradually decreased without the rear end protrusion that thermal current is advertised, to be distributed more sieve pores,
Increase screening percentage.Reinforce dispersion effect of the roller to rubbish.
Further drum sieve front end is stretched into the discharge port of the solid chemicals feed hopper.It adds to disperse cohesive soil
The solid chemicals of earth, such as lime block, fine sand improve dispersion effect.
Further the hot gas flow tube is tubaeform flat mouth, and tubaeform flat mouth width degree is the 1/3 ~ 1/2 of drum sieve length,
Tubaeform flat mouth is biased upward into seal closure.The thermal current pipe of tubaeform flat mouth forms a longer airflow inlet, fills
Point feed waste is heated using thermal energy, and can improve feed waste the roller other side whereabouts effect.
Basket strainer cotton, gas gathering mask outlet connection exhaust gas processing device are further equipped in the gas gathering mask.Basket strainer cotton
For getting rid of micronic dust, gas gathering mask can external activated carbon adsorption, solvent absorbing apparatus.
Further the seal closure rear and front end is equipped with flexible check apron.For gathering heat, thermal current is avoided to be lost in, together
When do not influence the disengaging of material.
The present invention also provides a kind of processing method for the device that mineral and municipal waste finely sieves, this method is：It opens
Driving wheel, driving drum sieve roll, 6 ~ 8r/min of rotating speed；Rubbish is delivered to drum sieve feed inlet by conveying device, is fed
Speed is 3 ~ 4m3/h；It is passed through hot-air, 40 ~ 70 DEG C of hot air temperature, 2500 ~ 3500L/min of flow velocity.Work of the material in roller
Throwing is turned under, water content declines under thermal current effect, is effectively disperseed in the case where disperseing raised role, passes through the present apparatus
Processing, fertile soil is sized out through sieve pore, and inorganic aggregates and light materials are then discharged in roller rear end and send to light materials
The tail gas such as the vapor evaporated, foul smell are led to exhaust gas processing device and handled by separator for further separation, gas gathering mask.
Further when rubbish water content is high, unlatching solid chemicals feeding hopper exit when sticking together adds solid chemicals.
It is further described to promote the medicament of dispersion for blocky lime, coarse sand, dry sandy soil, calgon and ammonium hydroxide
One or more of, adding proportion is the 0.5 ~ 5% of garbage bulk.
Advantageous effect：Compared with the prior art, the advantages of the present invention are as follows：
1）It is dried using hot-air, solving the problem of that feed waste moisture content is high reduces treatment effect, is provided for light materials separation
Necessary condition；
2）The dispersion protrusion and arrangement mode of setting can increase material lifting height and dispersion effect；
3）Dosing mouth is set, dispersion effect humous is improved；
4）Fertile soil screening percentage is more than 90% compared with the traditional round shaft screen of identical sieving area.
