Extrusion forming and packaging machine and system for forming and packaging garbage

Abstract

The invention provides an extrusion forming and packaging machine and system for forming and packaging garbage. The extrusion forming and packaging machine comprises a garbage forming machine and a wrapping film packaging machine body; a back pressure head capable of moving in the axial direction of the garbage forming machine is arranged at an outlet of an extrusion cavity of the garbage forming machine, and the back pressure head can be locked at or moved away from the outlet of the extrusion cavity of the garbage forming machine; and the back pressure head, an extrusion head and a wrapping head are matched to package a garbage bag from vertical faces, and the wrapping head and a belt conveyor are matched to package the garbage bag from planes. The extrusion forming and packaging machine and system for forming and packaging garbage have the beneficial effects that the unique design of the back pressure head and the extrusion head of the extrusion forming and packaging machine ensures packaging of the garbage bag and prevents the garbage bag from scattering; and meanwhile through accurate action cooperation of the back pressure head, the extrusion head and a film wrapping system, the garbage bag is discharged and packaged at the same time after being formed, scattering is avoided in the packaging process, and a wrapping film completely seals garbage blocks.

Description

technical field [0001] The invention belongs to the technical field of domestic waste treatment, and in particular relates to a treatment and packaging system for domestic waste. Background technique [0002] At present, landfill and incineration are still the main methods of domestic waste disposal. [0003] The main disadvantages of the landfill method are that it occupies a large area, has no garbage reduction effect, and the landfilled garbage has not been harmlessly treated. The stench, pathogens, heavy metals, and leachate of the garbage may cause harm to water, soil, and the atmosphere. Secondary pollution. In addition, the geological conditions in some areas of our country, such as karst landforms, are not suitable for the construction of garbage sanitary landfill areas, while land resources in developed areas are becoming more and more scarce, and it is becoming more and more difficult to select landfill sites. [0004] The incineration method can realize the redu...

AI Technical Summary

Problems solved by technology

[0005] At present, the collection and transfer of domestic garbage in various urban areas are more or less unable to avoid the secondary pollution in the process of traditional garbage removal and transportation, and there will be odor and leachate during the temporary storage of garbage

In addition, it takes a long time for waste incineration plants to go from demonstration, approval, site selection, land acquisition, construction preparation to completion and operation. During this period, waste can only be transported and temporarily stored in the previous way, or landfilled, which is not a good way. the solution
