The comprehensive municipal solid waste sorting machine in Embodiment 1 is started up in the following order: peripheral output equipment→air blowing system→blowing system→sorting drum→bag breaking mechanism and feeding conveying mechanism. The shutdown sequence when production is stopped is: bag breaking mechanism and feeding conveying mechanism → sorting drum → blast system → air delivery system → peripheral output equipment.

Embodiment 1 working process:

Household garbage enters the bag breaking box at the designed flow rate, and its chain reamer cooperates with the material guide vertical plate to break or scratch the packaging bags of garbage. At the same time, most of the organic matter with fragile texture and low strength is crushed into The block diameter below 60-100mm, such a large block diameter can be matched with the hole-shaped sieve diameter of this comprehensive separator to achieve the best separation effect. The chain reamer of the broken bag box will bend itself to let it pass through large pieces and hard objects without damage. The speed of the chain reamer is regulated by a speed-regulating motor, and the best speed is characterized by high bag breaking rate and smooth blanking.

The crushed mixed garbage is guided by the guide hopper into the rotating sorting drum, and the grating screen first screens out the sand and lime ash, glass ceramic fragments, hard plastic fragments and other impurity particles that are smaller than the gap. This part of garbage falls into the corresponding ash block material receiving hopper under the front section of the drum, and is output by the screw conveyor.

Due to the narrow width of the six long vertical boards on the inner wall of the sorting drum, the garbage is only tossed to the height below the blower during the rotation of the drum, so that the garbage in the front section of the drum is only screened out by sand and lime. , without participating in winnowing. Since the sand and lime are screened out in the front section of the sorting drum and do not participate in the subsequent winnowing, there is basically no dust in the whole sorting process, and very little dust is blown into the large sieve holes in the rear section of the drum.

The sieve hole of the hole-shaped sieve of the sorting drum can sort out the part of garbage that is smaller than 80-100mm and mainly consists of organic matter.

The short vertical plates distributed in steps on the inner wall of the rear section of the sorting drum can bring the garbage to the top of the axial flow wind belt passing through the drum in the axial direction and then fall down; The continuous spiral movement in the circumferential direction of the sorting drum causes the garbage to also move in a continuous spiral orderly manner, so within the rated design speed range, the number and sequence of each garbage participating in winnowing are unchanged. So the garbage is sorted very fully in the drum. Among them, light materials such as waste plastic bags and sheet and film plastics (mixed with a small amount of broken paper) are blown to the air-inducing material pipeline at the end of the sorting machine, and sent to the plastic processing workshop through the air delivery system.

The garbage mainly composed of organic matter selected by hole-shaped screening falls into the corresponding organic matter receiving hopper at the back of the drum, and is output to the subsequent treatment process such as high-temperature and high-pressure hydrolysis process through the screw conveyor.

Except for the access door opened during maintenance, the sorting box should be a sealed box under normal conditions. The sorting drum winnowing airflow points to the air-inducing material pipeline directly below the rear wall of the sorting box, so most of the light-weight plastics are blown out of the machine from here.

Since the cross-sectional area of the sorting box is larger than that of the drum, the wind force and wind pressure after entering the sorting box are greatly reduced. The materials mixed in the wind flow begin to fall one after another. The heavier objects and the heavy garbage rolled down by the sorting drum fall into the wet and heavy material receiving hopper. It is mainly wet garbage. After a little sorting, this part of garbage can be sent to the light-weight building material production workshop as raw materials to be made into light-weight building materials. What can be blown a little farther is that the dry woven fabrics, clothing and other combustible garbage fall into the combustible garbage receiving hopper, and this part of garbage is sent to the fuel workshop to be burned as a heat source in the process or burned in a special garbage incinerator can be.

Due to the change of the dry humidity of the material and the wind speed, the falling point of various materials will change during the sorting process. By adjusting the angle of each material baffle, different materials can be respectively dropped into the corresponding receiving hopper.

In order to achieve the best sorting effect, the following parts of Embodiment 1 should be adjusted and controlled: 1. The rotation speed of the sorting drum is adjusted by the speed-regulating motor; 2. The adjustment of air volume and wind force: except for the air inlet of the air cylinder and the adjustable damper , also selected the fan driven by the speed regulating motor. 3. In order to achieve the best bag breaking effect, the chain plate shaft of the bag breaking machine is driven by a speed regulating motor.
