Glass crushing method and crushing device

Abstract

The invention relates to the technical field of solid waste recycling treatment, is used for the garbage environment-friendly recycling industry, and particularly relates to a glass crushing method and a crushing device. According to the glass crushing method and the crushing device, the particle size of crushed glass particles can be effectively controlled in the glass waste crushing process, andthe formation of powdery glass particles can be greatly reduced, so that glass reclaimed material particles can be effectively detected, identified and screened out of high-temperature-resistant glass by a high-temperature-resistant glass detection device, the high quality of the recycled glass material is ensured, a large amount of waste glass regeneration products can be prevented from being scrapped, normal recycling of glass waste products is ensured, secondary waste of resources is avoided, and healthy development of the environmental protection industry is facilitated.

Description

technical field [0001] The invention relates to the technical field of solid waste treatment and recovery, and is used in the garbage environmental protection recycling industry, in particular to a glass crushing method and a crushing device. Background technique [0002] Glass is a material commonly used in people's daily life. For the sustainable development of resources, the existing technology makes waste glass recyclable through steps such as cleaning, crushing, and high-temperature melting. [0003] With the development of human technology, the demand for glass materials is also increasing. For example, doors and windows need to use ordinary glass, stage spotlights need to use colored glass, and electric heating devices such as induction cookers need to use high temperature resistant glass. Therefore, the material of glass is also divided into different categories. Since glass is artificially synthesized, the internal material has obvious differences, resulting in diff...

However, this screening method has requirements on the particle size of the cullet particles. If the particle size of the cullet particles is too small, it will affect the screening accuracy of the screening equipment. When broken into particles with too small particle size, it will be unrecognizable by screening equipment and continue to be mixed into ordinary glass, which still has the risk of causing a large number of glass products to be scrapped

[0008] In order to speed up the crushing speed of glass, the glass crushing device of the prior art can be roughly divided into two kinds of structures. One is to set two crushing rollers side by side in the device, and the glass waste is dropped between the two crushing rollers. The two crushing rollers crush and crush the glass waste, but during the crushing process, a part of the glass will be crushed into powder particles, resulting in a large amount of powder glass particles in the crushed glass particles, powder glass particles Because the particle size is too small to be identified by the screening device; another structure of the crushing device is to put glass waste into a high-speed rotating drum, and there are generally hard objects such as breaking hammers fixed in the drum, and the high-speed drum produces Centrifugal force makes the glass wastes collide with each other, or makes the glass wastes hit hard objects such as the breaking hammer in the drum, so as to quickly smash a large number of glass wastes. Due to the excessive speed of the drum in this way, the drum speed of individual equipment is even It can reach up to hundreds of revolutions per minute, which will cause the glass waste inside the drum to be broken by one impact and then continue to be repeatedly impacted repeatedly. The more impacts, the smaller the particle size of the broken glass particles, thus Accompanied by a large number of powdered glass particles, the end result is also cullet particles too small to be identified by screening devices

[0009] That is to say, after using the glass crushing device of the prior art to crush the waste glass, the crushed glass scrap will contain a large amount of powdered glass particles, which cannot be crushed by high temperature resistant glass due to the extremely small particle size of the powdered glass particles. The detection and identification of advanced screening devices eventually lead to a lot of powdery high-temperature-resistant glass particles continuing to be mixed into ordinary glass scrap, which seriously affects the quality of glass recycled materials

In summary, the inability to effectively control and reduce the powdered glass particles produced during the crushing process of glass waste products is a defect in the existing technology, which will directly lead to the inability to effectively detect and detect the high temperature resistant glass in the glass recycling scrap. Screening out makes the quality of glass recycled materials uncontrollable, resulting in the risk of a large number of waste glass recycled products, resulting in secondary waste of resources, which violates the original intention of waste recycling and reuse, and hinders the healthy development of the environmental protection industry
