Technical Field

The invention relates to the technical field of waste glass recycling, in particular to a roughing treatment system before dry automatic sorting and drying of waste glass.

Background

With the development of science and technology and the increasing improvement of the living standard of people, glass and products thereof are widely used in daily life of people, but a lot of glass waste is inevitably generated, and a large amount of cullet is formed. It is estimated that glass waste generated in China every year is up to 5000 ten thousand tons, and accounts for about 5% of the total amount of urban solid waste.

Although waste glass is a recyclable resource, the chemical properties of waste glass substances are stable, the waste glass substances are not rotten, combusted and almost not degraded, and a large amount of waste glass causes harm and inconvenience to the production and the life of people, causes pollution to cities, occupies precious land and increases environmental load. Various impurities doped in the waste glass are removed by adopting various sorting process technologies, so that the waste glass becomes recyclable cullet, and the method is an optimal solution for the waste glass.

The best treatment mode of the waste cullet is to be recycled as a renewable resource, not only because of the consideration of environmental protection, but also has the actual requirement of producing clean cullet. In glass production, the cullet is also called clinker, is an auxiliary raw material for producing glass, and is also a very effective fluxing agent. According to the data, the energy consumption can be reduced by 2-3% for every 10% of cullet, and more importantly, the melting of the cullet reduces the emission of greenhouse gases by about 200 kg per ton compared with the production of new glass products from raw ores.

A plurality of technical bottlenecks still exist in the waste glass recycling industry in China, the recycling and sorting links are extensive, a refined and automatic sorting technology is lacked, and a large number of washing wet-process production and manual sorting methods exist, so that not only are water resources wasted, but also the production wastewater pollutes the environment.

Before carrying out the drying edulcoration to useless glass, need reject comparatively obvious big impurity thing in the useless glass, rubbish such as fragment of brick, wood piece, cloth, plastic bag, plastic bottle, iron cover, current rejection equipment is selected separately effectually, and is inefficient, is difficult to satisfy the requirement.

Disclosure of Invention

The invention aims to provide a rough separation treatment system before dry automatic separation and drying of waste glass, which can remove large impurities in the waste glass, meet the treatment requirement of rough separation before drying and improve the treatment effect.

The technical scheme adopted by the invention for solving the technical problems is as follows:

the pre-roughing treatment system comprises a vibrating feeder, wherein a belt conveyor is arranged at an outlet of the vibrating feeder, the belt conveyor is provided with a self-discharging permanent magnet iron remover and an electronic belt scale, an L-shaped vibrating distributor and a bar vibrating screen are sequentially arranged at an outlet of the belt conveyor, and a first manual sorting belt conveyor and a second manual sorting belt conveyor which are parallel to each other are respectively arranged at an outlet of the bar vibrating screen; the outlet of the first manual belt-selecting conveyor is provided with a pneumatic three-way distributor, and two distributing openings of the pneumatic three-way distributor are respectively provided with a single-section hammer crusher and a double-roller crusher; the outlet of the double-roller crusher is sequentially provided with a finger-type screen and a winnowing machine; and outlets of the second manual hand-selection belt conveyor, the single-section hammer crusher and the finger-type screen are connected to a waste glass drying system through the conveyors.

The beneficial effect of the invention is that,

firstly, a composite separation is formed by adopting various separation technologies such as magnetic separation, screening separation, manual separation, wind separation and the like, and the separation problem of different impurities such as ferrous metal, bulk impurities, bottle caps and the like is solved.

And secondly, the daily glass can be automatically sorted, and the plate glass can be automatically sorted.

Detailed Description

As shown in fig. 1, the invention provides a rough separation treatment system before dry automatic separation and drying of waste glass, which comprises a vibrating feeder 1010, wherein a belt conveyor 1020 is arranged at an outlet of the vibrating feeder 1010, the belt conveyor is provided with a self-unloading permanent magnet iron remover 1030 and an electronic belt scale 1040, an L-shaped vibrating distributor 1045 and a bar vibrating screen 1050 are sequentially arranged at an outlet of the belt conveyor 1020, and a first manual separation belt conveyor 1065 and a second manual separation belt conveyor 1060 which are parallel to each other are respectively arranged at an outlet of the bar vibrating screen 1050; the outlet of the first manual belt-selecting conveyor is provided with a pneumatic three-way distributor 1095, and two distributing openings of the pneumatic three-way distributor are respectively provided with a single-section hammer crusher 1100 and a double-roller crusher 1110; a finger-type screen 1120 and a winnowing machine 1125 are sequentially arranged at the outlet of the double-roller crusher 1110; the outlets of the second manual hand-off belt conveyor 1060, the single-stage hammer crusher 1100, and the finger screen 1120 are all connected to the waste glass drying system by conveyors.

Waste glass is uniformly fed to a lower belt conveyor 1020 through a motor vibration feeder 1010 controlled by a variable frequency, when the belt conveyor conveys the waste glass, partial iron impurities in the waste glass are removed through a self-discharging permanent magnet iron remover 1030, the waste glass can be weighed through an electronic belt scale 1040, then the waste glass is uniformly spread out and distributed to a bar vibration screen 1050 through an L-shaped vibration distributor 1045, the bar vibration screen 1050 screens out whole bottles or large glass blocks to be crushed and conveys the whole bottles or the large glass blocks to a first manual selection belt conveyor 1065, the rest of the glass blocks are conveyed to a second manual selection belt conveyor 1060, and the two manual selection belt conveyors remove large and obvious impurities in the waste glass, such as bricks, wood blocks, cloth strips, plastic bags, plastic bottles, iron covers and the like; the first manual belt-selecting conveyor 1065 feeds the whole bottle or large glass into a pneumatic three-way distributor 1095, if the glass is flat glass, the glass enters a single-section hammer crusher 1100 to be crushed, if the glass is daily glass, the glass enters a double-roller crusher 1110 to be crushed, the daily glass is crushed, then enters a finger-type sieve 1120 to sieve out bottle heads and bottle caps, the bottle bottoms, the bottle heads and the bottle caps which are not sieved out enter a winnowing machine 1125 together, and the lighter bottle caps and the heavier glass are separated by the wind power action of a variable-frequency control blower; finally, the waste glass is conveyed to a waste glass drying and impurity removing system in the next process through the outlets of the second manual hand-sorting belt conveyor 1060, the single-stage hammer crusher 1100 and the finger-type screen 1120.
