Problems solved by technology

[0002] However, at present, due to the rapid growth of population and the development of urbanization, the construction industry in central cities develops rapidly, and old buildings are torn down and demolished every day, resulting in more and more construction waste (among them, waste concrete accounts for 34%). In order to meet the needs of civil air defense and building functions, newly built multi-storey high-rise buildings adopt basement and pile foundation structures. The concrete horizontal support beams of the foundation pit and the pile heads of the overfilling project need to be removed, and a large number of concrete test blocks for construction projects are discarded. landfill
Landfilling of construction waste not only wastes resources, pollutes the environment, and destroys ecology, but also takes up a lot of land.

Embodiment 1

[0021] Embodiment 1: A kind of household garbage regeneration disposal process provided in this embodiment, it comprises the following steps:

[0022] (1) Collection: collect domestic construction waste and collect it in the silo;

[0023] (2) Wind separation: transfer the domestic construction waste in the silo to the wind separation box through the conveyor belt to remove tiny foreign matter; preferably, the wind separation box is a vertical frequency conversion wind separation machine, which will Light matter waste is screened out.

[0024] (3) Primary crushing: Transfer the air-selected domestic construction waste to a crusher for crushing through a conveyor belt, and then pass through a sieve with a sieve hole of 0.5-40mm to obtain a semi-finished crushed stone; preferably, the crushing The machine is a high-pressure roller mill, and the crushing process of the high-pressure roller mill is closed-circuit crushing.

[0025] (4) Magnetic separation: the semi-finished crus...

Embodiment 2

[0032] Example 2: This example provides a domestic waste recycling process and recycled concrete products made of crushed stones using the domestic waste recycling process, which are basically the same as in Example 1, the difference is that the recycled concrete products The components and their mass percentages are as follows: 11% cement, 3% fly ash, 44% sand, and 42% crushed stone products.

Embodiment 3

[0033] Example 3: This example provides a domestic waste recycling process and recycled concrete products made of crushed stones using the domestic waste recycling process, which are basically the same as in Example 1. The difference is that the recycled concrete products The components and their mass percentages are as follows: 8% cement, 5% fly ash, 35% sand, and 42% crushed stone products.

Abstract

The invention discloses a household garbage regeneration disposal process. The process comprises the following steps: (1) collecting; (2) carrying out air separation; (3) carrying out first-stage crushing; (4) carrying out magnetic separation; (5) carrying out water separation; (6) carrying out second-stage crushing, so as to obtain a gravel product of 5-25mm. The invention further discloses a recycled concrete product made from the gravel product prepared by the household garbage regeneration disposal process. The household garbage regeneration disposal process disclosed by the invention is simple and easy in production process and easy in realization, can be used for solving the problem of regeneration utilization of household and construction wastes, and is used for rapidly producing the gravel product applicable to building materials; buildings constructed from the product produced by the process are good in structural strength, large in weight capacity, long in service life, light in self weight, low in cost, simple and convenient in processing and convenient in production and procurement, and have environment-friendly and economical characteristics, so that the competitive power is increased, and economic and social benefits are good.
