Structural characteristics and working principle of domestic waste sorting machine

Preface: Solid waste sorting in daily life waste treatment is to separate the recyclable materials or materials that are not conducive to subsequent treatment and disposal process requirements from solid waste. It is an important link and one of the important equipment in solid waste treatment projects. The domestic waste sorting machine effectively sorts various materials in the garbage, realizes the garbage classification for the purpose of resource utilization, and also collects and treats gas and dust to improve the working environment and reduce secondary pollution to the environment. The domestic waste sorting machine is an automated garbage treatment equipment that classifies mixed garbage through physical, chemical or biological technology.

With the improvement of environmental awareness and the continuous advancement of technology, domestic waste sorting machines are also constantly updated. The sorting machine in the future will be more intelligent, able to identify more types of items and improve the accuracy of sorting. At the same time, it will also combine technical means such as the Internet of Things and big data to realize the intelligent management and optimized scheduling of garbage treatment.

A. Main structure of domestic waste sorting machine:

1. Conveyor belt: used to send mixed garbage into the sorting machine.

2. Screening equipment: such as vibrating screen, drum screen, etc., used for preliminary screening according to the size and shape of the material.

3. Magnetic separator: used to separate magnetic materials such as iron from garbage.

4. Air separator: uses aerodynamic principles to separate light items (such as paper and plastic bags) from heavy items.

5. Optical sorter: uses high-resolution cameras and complex image processing algorithms to further classify items according to their color, shape and other characteristics.

B. Main features of domestic waste sorting machine:

1. The integrated sorting equipment has a simple structure, convenient manufacturing and maintenance, strong adjustment ability, suitable for different processing scales, and is conducive to promotion and application.

2. The sorting machine has a large diameter, low speed, stable operation, low noise, small footprint and easy installation.

3. It integrates sorting, bag breaking and packaging, and is suitable for sorting domestic waste in various communities.

4. The sorting efficiency is high, the sorting effect is obvious, the transportation cost is reduced, and the sorting process is simplified.

C. Working principle of domestic waste sorting machine:

The domestic waste sorting machine mainly works based on the differences in physical properties between different wastes, as well as the application of advanced sensing technology and artificial intelligence algorithms. Specifically, it uses vibration screening, wind separation, magnetic separation, optical recognition and other technical means to effectively separate different components in mixed garbage according to the weight, density, size, shape, magnetism, color, shape and other characteristics of the material.

When the solid waste enters the entrance of the sorting machine from the belt conveyor, it is first rotated and sorted by a large sorting shaft in a section and then sent to the discharge area. The first sorting shaft is equipped with three-divided row spacing and dozens of spring steel bars to carry out rolling sorting, magnetic suction, bag breaking and other process flows for the input garbage. The second four-divided sorting shaft receives the materials and sends the sorted diapers for the elderly and children, cartons, wood, etc. to the belt discharging machine at the first discharging port and then to the baler for packaging. Two groups of dozens of bag-breaking trapezoidal blades are set between the first sorting shaft and the second sorting shaft. The garbage sorted by the above two shafts are mainly wine bottles, plastic bottles and bricks, which are sorted by the third six-divided shaft and then sent to the belt conveyor at the second discharging port by rotation and then to the baler. The remaining toilet paper, vegetable leaves, small rags, etc. are sent to the belt conveyor at the third discharging port through the vibration of the grille mesh plate and then to the baler. The fourth discharging port is mainly No. 5 batteries, stones, glass and porcelain fragments, etc., which are discharged through the vibrating inclined mesh plate; the remaining is sewage.

PS: Domestic garbage sorting machine is an indispensable part of urban garbage treatment. It not only improves the efficiency and effectiveness of garbage disposal, but also promotes the recycling of resources and reduces the burden on the environment. With the continuous development of technology, domestic garbage sorting machines will play a greater role in urban garbage disposal in the future.
