Municipal domestic waste bag-breaking crushing equipment

Abstract

The invention discloses municipal domestic waste bag-breaking crushing equipment mainly comprising a feeding device, a bag-breaking crushing device, a driving device, a clearing device, a bulk waste outlet, a small waste outlet, an electric protective device, and the like, wherein a roller raft inside the bag-breaking crushing device is provided with a toothed sheet; and the rotary roller raft and the toothed sheet can break bags of upper mixed wastes multiple times and sufficiently crush organic matters, and therefore the problems of bag breaking and selective crushing in waste sorting are thoroughly solved. The municipal domestic waste bag-breaking crushing equipment disclosed by the invention doses not forcedly crush integral hard objects (such as bricks, stones, glass bottles, and the like), which can be directly recovered, in the wastes, thereby the influence of brick and stone crushed slag on the recycling of the wastes is prevented, the manufacturing cost of the equipment can be effectively reduced, and the operating cost (the abrasion of the toothed sheet, crushing energy consumption, and the like) of the equipment can be reduced; the roller raft and the clearing device for the toothed sheet can make the broken bags free from winding, thereby ensuring the equipment to continuously and stably operate; in addition, the equipment can also be additionally provided with a further sorting device, an air purification device, and the like for improvement, thereby the integral technological level of the equipment is increased.

Description

technical field [0001] The invention discloses bag-breaking and crushing equipment for municipal domestic garbage, which belongs to the field of solid waste treatment. Background technique [0002] Statistics show that the world's municipal solid waste production is 490 million tons per year, with an average annual growth rate of 8.42%; China's municipal solid waste production is nearly 150 million tons per year, with an average annual growth rate of more than 10%, and its growth rate is comparable to GDP growth rate. [0003] At present, the cumulative stock of domestic 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...

AI Technical Summary

Problems solved by technology

[0009] The problem with this type of garbage crusher is that the whole hard objects (such as bricks and stones, glass bottles, etc.) are broken by force, and the debris has a great impact on the quality of fertilizer made from garbage organic matter.

There is also the problem of stagnation of hard-to-break objects at the rear end

There is also no material cleaning device for the crushing plate and the toothed needle, which cannot solve the problem of thin shaft winding during the bag breaking process

It is difficult for the equipment to run continuously and stably
