City garbage specification recovery processing device

Abstract

The invention relates to an urban garbage sorting recycling treatment device which comprises a cracking device used for carrying out primary cracking on the garbage after being primarily sorted, a gravity sorting device used for sorting the materials after primary cracking into heavy materials and light materials, a heavy material cracking device used for cracking the heavy materials, a heavy material magnetic separation device used for carrying out magnetic separation on the heavy materials after being cracked and a light material cracking device used for cracking the light materials. The discharge opening of the cracking device is connected with the feed opening of the gravity sorting device; the heavy material discharge opening of the gravity sorting device is connected with the heavy material cracking device; the light material discharge opening of the sorting device is connected with the light material cracking device; the back surface of the heavy material cracking device is provided with the magnetic separation device; the discharge opening of the light material cracking device is connected with a firedamp device. The device takes most urban garbage as the materials that can be recycled and carries out the sorting and treatment on the garbage, which is beneficial to leading most urban garbage to obtain reclamation utilization.

Description

technical field [0001] The invention relates to a garbage processing device, in particular to a sorting recovery and processing device for urban garbage, and belongs to the technical field of environmental protection. Background technique [0002] Municipal waste has a wide range of sources, complex components, and difficult treatment. At present, except for a small amount of materials that can be directly recycled through manual sorting for recycling, most of them are landfilled and incinerated. However, these treatment technologies have disadvantages that cannot be ignored. For example, landfill needs to occupy a site, and can pollute groundwater and air. Incineration requires energy consumption, and its flue gas also contains harmful gases and suspended particles. , governance is also very difficult. Due to the improvement of people's living standards and the development of urbanization, the output of urban garbage is increasing, and the continuous use of landfill and in...

Problems solved by technology

Therefore, people began to continuously explore the ways of resource utilization of garbage materials. One of the important aspects is the classified collection of garbage, which is processed separately after sorting. There are two major categories of garbage and non-recyclable garbage. After the garbage is generated, these two categories of garbage are placed in different containers for collection. Among them, the so-called recyclable garbage can be directly used as industrial raw materials. Materials, such as plastic, metal and glass, etc. The so-called non-recyclable garbage refers to other materials that cannot be directly used as industrial raw materials or materials with low value when used as industrial raw materials

Although this method has been generally approved by people, there are still some problems in practice. One is that people often do not sort garbage in order to save trouble, and the other is that this sorting method includes most of the municipal garbage as non-recyclable. column, does little to reduce the amount of waste that landfills and incinerates
