Embodiment 1

[0024] In this example, refer to figure 1 , This embodiment provides a treatment and recycling process for brass waste, which mainly includes steps including shear crushing, magnetic sorting, wind sorting, particle sorting, specific gravity sorting, airflow sorting, and manual sorting. Specifically, the method of each process step is as follows:

[0025] (1) Shearing and breaking:

[0026] Due to the different sizes of brass scraps in life, some brass scraps are relatively large in size, so the brass scraps need to be cut and broken first. Preferably, in this embodiment, a shearing machine is used to first cut the brass waste, and then the cut brass waste is added to a crusher, and the brass waste is crushed to a particle size below 40mm by the crusher. Then the crushed materials are transported to the magnetic separation system, so that the materials can be magnetically separated in the next process.

[0027] (2) Magnetic separation:

[0028] Since the brass waste contain...

Embodiment 2

[0042] On the basis of Embodiment 1, the crusher in the shearing and crushing step in this embodiment can use a single-roll crusher and a hammer crusher; the single-roll crusher is used for primary crushing of the brass waste; The hammer crusher is used for secondary crushing of the primary crushed brass scrap. By crushing the brass scrap twice to make the brass scrap reach the required size.

Embodiment 3

[0044] On the basis of Embodiment 1, in the magnetic separation step in this embodiment, a belt-type iron remover is installed above the conveyor belt, and the iron remover can be a magnet with strong magnetic force. , the iron remover will absorb the magnetic metal substances in the crushed materials, thereby separating the magnetic metal substances and non-magnetic substances. Preferably, the magnetic metal substances separated in the magnetic separation step include finished iron and iron-containing materials, and the finished iron is for direct sale.

Abstract

The invention is applicable to the technical field of resource recycling, and provides a brass waste processing and recycling technology. The technology comprises the main steps of cutting, smashing,magnetic separation, wind separation, particle separation, proportion separation, airflow separation and artificial separation so that substances such as brass, plastic and rubber are obtained for recycling. Compared with a traditional artificial screening method, the technology has the advantages of high automation, concentrated management is facilitated, the manual labor intensity is greatly reduced, meanwhile, the separation of each substance can be more effectively achieved, the product quality is improved, the loss is reduced, and the maximum benefit is achieved.

Description

technical field [0001] The invention belongs to the technical field of resource recovery, and in particular relates to a process for processing and recycling brass waste. Background technique [0002] As the population continues to increase, the various materials used by human beings increase accordingly. However, after each material has been used for a period of time, when it is partially damaged or old or no longer needed, users often discard it. , become waste. With the continuous strengthening of environmental protection awareness, people pay more and more attention to the environment and protection of the entire earth, and vigorously advocate and promote the recycling and reuse of waste and other materials to protect and protect the earth environment in which we live together. With the continuous improvement of the awareness of environmental protection in the whole society, people have paid more and more attention to the recycling of waste materials. [0003] In today...
