Recovering and classifying system for cullet

Abstract

The invention especially relates to a recovering and classifying system for cullet, belonging to the field of environmental protection equipment. According to the invention, a material washing pipe is arranged above a material discharging end of a slide rail and connected with the bottom of a water storage tank via a pipeline; a water outlet is formed in the bottom of the material washing pipe; cullet to be recovered is dirty and needs cleaning so as to increase the transmittance of light penetrating the cullet; a lamp source is arranged above the material discharging end of the slide rail; the material discharging end of the slide rail is further provided with a sensor and an air jet hole; and the air jet hole is connected with a high-speed air valve through a flexible pipe. When the cullet is passing through the material discharging end of the slide rail, the lamp source directly irradiates the cullet; the sensor identifies the transmittance of light penetrating the cullet so as to realize classification of transparent glass and colored glass; and in virtue of the high-speed air valve, the colored glass with low transmittance is allowed to fall into a second recovery tank through blowing, and the transparent glass with high transmittance is allowed to directly fall into a first recovery tank. The recovering and classifying system provided by the invention is simple in structure, high in identification rate, good in classification effect, environment friendly, energy-saving and safe to use.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a recovery and classification system for broken glass. Background technique [0002] Glass is formed by melting together sand and other chemicals (mainly produced from: soda ash, limestone, quartz). A silicate non-metallic material that forms a continuous network structure during melting and gradually increases in viscosity and hardens during cooling. The chemical composition of ordinary glass is Na2O·CaO·6SiO2, and the main component is silicon dioxide. Widely used in buildings, used for wind and light transmission, belongs to the mixture. There are also colored glass that is mixed with certain metal oxides or salts to show color, and tempered glass made by a special method. The recycling of glass waste is particularly important. In order to achieve sustainable development, old glass bottles are recycled. It can save money, better deal with the harm of garba...

Problems solved by technology

Manual selection is not only time-consuming and labor-intensive, but also has low efficiency, and there are certain potential safety hazards. However, machine selection in the market is generally done by using a color sorter. The effect of selecting products other than glass by using a color sorter is not bad, but when selecting broken glass, the effect is relatively poor, and the expected effect cannot be achieved.
