Description
Technical field
The utility model provides a kind of aciculiform vibration screening device for house refuse, to broken house refuse into
Row screening, solves and twines that material, putty, adhesion, screening efficiency is low, energy consumption is high, noise existing for traditional life sieving garbage device
The problems such as big, belongs to domestic waste preconditioning technique field.
Background technique
In Disposal of Municipal Refuse field, since the ingredient of house refuse is extremely complex, not by broken
House refuse screening effect it is bad, rubbish from cooking separation rate is extremely low, far from reach biodegrade require and oversize resource
Change and require, brings high cost for the processing of rear end.The house refuse being crushed is sieved by traditional screening mode, sieve
Divide effect bad, the very short time sieve pore of process just blocks severity, and screen axis sieve will be wound.Keep the sieve pore of screening machine fast
Speed becomes smaller, and a large amount of rubbish from cooking and oversize are mixed together, and screening efficiency sharply declines.Matched other pretreatments
Equipment disposal ability also reduces.The time of house refuse pretreatment system equipment processing house refuse further extends.Serious shadow
Treatment effeciency is rung.
Traditional life sieving garbage system, it is bulky, occupy a large amount of space.Complicated in mechanical structure, noise are big.Before
Latter linked other pre-processing devices are also complicated, this has resulted in the high failure rate of screening plant.Sieve the apparatus sanitation finished
Cleaning be also required to take more time.Rubbish from cooking tails off under sieve after especially traditional sieving technology screening, on sieve
Rubbish from cooking becomes more, brings difficulty for rear end biodegrade and the comprehensive utilization of front end RDF.So being badly in need of a kind of novel height
Effect, space occupied is small, low energy consumption, the house refuse screening plant of high reliablity crack presently, there are problem.
Summary of the invention
The utility model discloses a kind of aciculiform vibration screening device for house refuse, by (the modeling of biggish house refuse
Material, fabric etc.) it effectively carries out vibrating with lesser house refuse (food waste, plastic sheet, sundries) leaving screening, big RDF quilt
It bounces, small rubbish from cooking is fallen along the gap that needle sieves, and it is extremely low to rubbish from cooking separation rate to solve traditional screening plant, sieve
The defects of point effect is bad, and sieve pore just blocks severity, and screen axis sieve will be wound.
A kind of house refuse aciculiform vibrosieve method described in the utility model, technical solution are as follows:
On the aciculiform vibrating screen that uniformly rubbish is transported to and is disposed below by conveyer for domestic waste structure, aciculiform vibration
Dynamic sieve is arranged on the rack by capacity eccentric bearing, and the upper and lower sieve needle of aciculiform vibrating screen is elongated streaky shape, in the drive of motor
The dynamic lower circumference shake for generating decentraction forms a throwing power forward and up, so that bulk using the elasticity of upper and lower sieve needle
Non- rubbish from cooking lodge with strip is on upper sieve needle, and shorter non-food waste fragment and rubbish from cooking are together along upper and lower sieve
The gap of needle carries out selection by winnowing according to density size, the volume size of rubbish by the winnowing machine of bottom of the frame and collects respectively toward falling.
The sieve needle up and down and level of the utility model aciculiform vibrating screen have certain adjustable angle tilted down, sieve on needle
There is a forward inclination angle in the direction and vertical direction vibrated when lower vibration, sieves needle under the action of driving motor and capacity eccentric bearing
A throwing power forward and up is formed, material constantly moves forward in setting point when moving up and down on vibration sieve, due on sieve needle and sieve
The vibration frequency of object is different.Oversize will not occur to wind and accumulate.Sieving sieve needle due to aciculiform has downward inclination angle, passes through drive
It is dynamic to adjust running frequency, using sieve needle rigidity and flexible combine, combined using the gap and inclination angle of sieve needle, using inclined
Heart vibration is combined with gravity, is subject to pneumatic separating for auxiliary, is greatly improved the screening efficiency of aciculiform sieve screening machine, is sieved pure
Degree is also greatly improved than traditional screening plant.Reduce the volume of aciculiform screening machine substantially by the utilization combined above, energy consumption
It is greatly reduced, occupied area and space have apparent advantage than traditional garbage sieving device.
So that the non-food waste material lodge of bulk and strip is constantly transported to the export direction of screening machine on sieve needle
It is dynamic.Be spread to sieve needle gap in lesser food waste organic matter material fall in organic matter material collection case, be spread to sieve needle on compared with
For small food waste organic matter material since contact area is smaller, stress is more dispersed, under the action of the elastic force of side under fall on it is organic
In matter material collection case.
Shorter non-food waste fragment and food waste material are mounted on sieve together along the past whereabouts in gap on upper layer, lower screen needle
