Bag-breaking and sorting integrated equipment for municipal domestic waste

Abstract

The invention discloses bag-breaking and sorting integrated equipment for municipal domestic waste. The equipment mainly comprises a bag breaking and crushing device, a drive device, a material cleaning device, a composite sorting device, a discharging device and the like. Serrated knives on a roller row in the bag breaking and crushing device perform effective bag breaking on bagged and mixed municipal domestic waste and full crush on organisms; material cleaning mechanisms of rollers and the serrated knives can ensure the winding-free continuous operation of garbage bag breaking; and the equipment does not perform forced crushing on articles which are difficult to crush so as to avoid adverse effects of crushed brick and stone slag on the composting of the organisms, and the harm of crushed waste batteries and the like. The cost of the equipment can be reduced; and the abrasion of blades and the operation cost of the crushing energy consumption and the like are reduced. By adopting an advanced integrated sorting technology, the composite sorting device is used for thoroughly sorting the garbage subjected to bag breaking, and sorting high-purity components such as plastic bags, organisms, inorganic matters, plastic containers, soft packages, glass bottles, waste metal, batteries and the like, thereby contributing to the recycling of various resources.

Description

technical field [0001] The invention relates to an integrated equipment for bag breaking and sorting of municipal domestic garbage, which belongs to the field of solid waste treatment. Background technique [0002] The accumulative stockpile of municipal solid waste in my country has reached 7 billion tons, covering an area of ​​more than 800,000 mu, and continues to grow at an average annual rate of 4.8%. It has become one of the most serious countries in the world where the cities are surrounded by garbage. Most of the cities in our country have no suitable places to pile up and landfill urban domestic garbage. The "crisis" of municipal solid waste has arrived! [0003] Municipal solid waste is a kind of "resource" and an inexhaustible "treasure" with the most development potential! Municipal solid waste hides huge wealth. Studies have shown that through resource treatment, my country's municipal solid waste can create 25 billion yuan of renewable resources every year. ...

AI Technical Summary

Problems solved by technology

[0010] However, the low cost of the equipment, the crushing knife assembly on the high-speed bag-breaking drum, the eccentric drum and the telescopic rod on the feeding drum, etc., restrict its popularization due to problems such as complex structure, high manufacturing cost, high operation failure rate, and difficult replacement. application

At the same time, the garbage is from top to bottom, and the crushing knife on the low and high-speed bag crushing drum is also from top to bottom, which can easily cause the problem of broken bags and poor crushing effect.
