Since the 1970s, China has gradually adopted the method of landfilling to treat urban household waste. Due to the advantages of low investment, simple process, convenient management, wide applicability, and low maintenance costs of landfill methods, based on China's economic and technological level and the composition of urban household waste, for a long period of time in the future, landfill will still be the main method of urban household waste treatment in China. Due to the lack of effective protective measures during the operation of some informal landfills, pollution such as water, gas, and odors is generated, which not only affects the lives of surrounding residents but also pollutes groundwater.
After the 19th National Congress of the Communist Party of China, environmental protection projects have been listed as a top priority in the country's sustainable development strategy, and "source reduction" has been taken as an important measure to solve the problem of urban waste disposal. A series of policies have been introduced, indicating that garbage classification will soon be widely implemented nationwide as a policy related to national economy and people's livelihood. It can be seen that the rational and harmless treatment of stale garbage is urgently needed.
The treatment of stale garbage generally faces problems such as large landfill volume, complex composition, and difficult sorting. Professional stale garbage treatment equipment solves these problems by using multi-level sorting, multi-mode sorting, and multi-level sorting to effectively solve the problem of complex composition of stale garbage. The final materials can be formed according to customer needs (humus soil, light substances, heavy substances, combustibles, non combustibles, etc.). On the premise of ensuring sorting efficiency, a large amount of stale garbage can be processed simultaneously to meet the on-site processing schedule requirements of customers.
The following is an introduction to the main equipment of the stale garbage treatment line:
1、 Chain plate feeder+fabric feeder
The plate feeding fabric machine is composed of a chain plate feeding conveyor and a uniform fabric spreader. The garbage is transported to the head feeder by a plate feeder, and after several cycles, the required fabric effect is obtained. At the same time, the material flow rate is controlled to achieve better usage effect.
2、 Magnetic separator
When garbage passes under the fixed magnetic separator magnet, the magnetic substance is adsorbed onto this conveyor belt and moves along with it. When the magnetic substance is sent to the small magnetic area, it automatically falls off, thereby achieving the recovery of the magnetic substance.
3、 Drum screen
The shaftless drum screen is a universal screening equipment for comprehensive sorting of household waste, used for grading materials. Control the particle size of materials through the size of sieve holes for grading.
4、 Plate selection sieve
The role played in the production line is to grade materials and remove debris, using multi axis rotation to push materials forward along the screen surface, while the rapid rotation of the screen disc loosens the materials. Materials smaller than the gap between the sieve holes are subject to their own weight and the rotational force of the sieve disc, falling through the gaps between the sieve shafts. Materials larger than the gap between the sieve holes remain on the sieve surface and continue to move forward, falling into the conveyor belt to achieve the purpose of screening.
The Guoxin Machinery Aged Waste Treatment Line has the characteristics of high integration, simple and easy maintenance of equipment, few vulnerable parts, and long service life. Its integrated intelligent operating system can achieve remote start-up and dynamic fault alarm, with simple operation and greatly reducing labor costs.
The Guoxin Machinery Aging Waste Treatment System is a product of the times, which can effectively realize the resource utilization, harmlessness, and reduction of on-site processing of aging waste.
