Rubbish screens out the soil that partial size is less than particle size values D greater than particle size values D building waste block and partial size, 25mm≤D≤60mm；
S30: transhipment process, wherein soil of the partial size less than particle size values D enters belt conveyor, and passes through belt conveyor
It is transported on mobile vehicle equipment；Partial size is greater than particle size values D building waste block and falls into the area that gathers materials, and unified recycling is to subsequent processing.
Preferably, in step 20, building waste is transported in rotary screen by apron conveyor with the speed of 0-0.5m/s.
Preferably, the mobile vehicle equipment is self-tipping type automobile.
Preferably, the apron conveyor is speed-adjustable apron conveyor.
Preferably, the leakage with retractable discharge port is provided between the belt conveyor and the mobile vehicle equipment
Building waste is transported to funnel bin by hopper, the belt conveyor, and the mobile vehicle equipment is by building in the funnel bin
After building refuse is filled, the discharge port is closed.
Compared with prior art, the beneficial effect for the pretreatment method that building waste of the invention screening removes soil is: passing through
Building waste screening of the invention can separate the soil in building waste with building waste block except the pretreatment method of soil, and will
Isolated soil is used as backfill.
Detailed description of the invention
Fig. 1 is building waste screening of the invention except the process flow chart in the pretreatment method of soil.
In figure:
1- apron feeder；2- apron conveyor；3- rotary screen；4- belt conveyor；5- funnel bin；The mobile delivery of 6- is set
It is standby；7- scrapers.
Specific embodiment
Technical solution in order to enable those skilled in the art to better understand the present invention, with reference to the accompanying drawing and specific embodiment party
Formula elaborates to the present invention.
As shown in Figure 1, the preferred embodiment of the present invention provides a kind of pretreatment method of the building waste screening except soil, institute
Building waste screening is stated except the pretreatment method of soil includes following process:
S10: entering material process, it is described enter material process include:
S11: building waste is transported in the additive bin of apron feeder 1 using scrapers 7；
S12: building waste enters through additive bin on the equipment of apron feeder 1, makes to build rubbish by harmonious material device
Rubbish realizes homocline；
S13: building waste enters apron conveyor 2 after harmonious material device homocline；
S20: disposition process, wherein building waste is transported to by apron conveyor 2 with the speed of 0-0.5m/s to be had centainly
In the rotary screen 3 of height, rotary screen 3 will build rubbish with the speed rotary screen of setting, screen size φ=40mm, rotary screen 3
Rubbish screens out building waste block of the partial size greater than 40mm and partial size is less than the soil of 40mm；
S30: transhipment process, wherein partial size less than 40mm soil fall into screen drum under B=1200mm belt conveyor
On 4, and funnel bin 5 is transported to by belt conveyor 4, and building waste is fallen by mobile vehicle equipment 6 by funnel bin 5
On, funnel bin bottom has an openable and closable discharge port, after the building waste in funnel bin fills mobile vehicle equipment 6,
Openable and closable discharge port is closed, and building waste is transported to designated place and backfilled by mobile vehicle equipment 6；Partial size is greater than 40mm
Building waste block falls into the area that gathers materials, and unified recycling is to subsequent processing.
Specifically, the characteristics of above-mentioned device therefor itself are as follows:
Apron feeder 1: carrier bar thereon can carry out the adjusting of self-operating speed according to the amount of supplied materials, and harmonious material device can
Even feeding is realized, this ensures that feed is uniform and stable；
Apron conveyor 2: the intermediate diaphragm plate height designed according to the particle size range of building waste, equipment surrounding, which has, encloses
Gear, will not be there is a situation where arbitrarily running when such building waste is conveyed with larger angle, and conveyer is closed tight, change significantly
The problem of kind production environment dust；
Rotary screen 3: being attached to the sieve plate of rotor inner wall, is rotated, is not vibrated, noise control with the linear velocity of setting
It is good.Sieve nest is fully sealed, and ease dirt effect is preferable.Due to screening efficiency height, it can be well adapted for the own characteristic of building waste,
It is not easy stifled sieve, separation performance is good.
Preferably, the mobile vehicle equipment 6 is self-tipping type automobile.
The advantages of building waste screening of the invention is except native pretreatment method are as follows:
(1) power consumption for the equipment that the pretreatment method utilizes adds up to 0.32kgce/t, and energy consumption is very low；
(2) apron feeder 1 and harmonious material device feeding are used, the unstability of forklift feeding can be converted to stably feeding
Equipment, overcome the unstable disadvantage of common hopper feeding；
(3) the characteristics of conveying building waste using apron conveyor 2, capable of more meeting building waste, avoids common conveying
Machine zone face serious wear often replaces the case where zone face；
(4) rotary screen 3 is smaller than vibrating screen energy consumption；3 sieve plate of rotary screen uses circular geometry hole, and material is rolled in screen drum turning in,
It is not easy plug-hole, for screening efficiency up to 90% or more, screening efficiency is high, suitable for containing the material of certain moisture, the purity is high of product,
And equipment does not need to vibrate, 60 decibels of level of noise < at distance of the equipment zero load apart from equipment 1m, operation noise is small；Equipment itself
It is totally-enclosed, it is suppressed that dust escapes, while reducing level of noise, and the environmental protection standard than general vibrating screen is higher；
(4) for processing line disposing capacity up to 120t/h, processing capacity is high, is fully available for measuring high building containing soil on a large scale
The pretreatment technology of rubbish.
Above embodiments are only exemplary embodiment of the present invention, are not used in the limitation present invention, protection scope of the present invention
It is defined by the claims.Those skilled in the art can within the spirit and scope of the present invention make respectively the present invention
