An electro-hydraulic system and method for improving garbage compaction

Abstract

The invention discloses an electro-hydraulic system and method for improving the compaction degree of garbage. The electro-hydraulic system comprises a pressure oil way, an oil return circuit, a firstreversing valve, a second reversing valve, a compression oil cylinder, a feeding oil cylinder and an automatic control unit. According to the electro-hydraulic system, partial air and moisture in a plurality of small spaces inside the garbage are discharged through each squeezing of the garbage, and the withdrawn garbage partially rebounds, so that a plurality of small space discharging channelsare communicated, and most of air and moisture can be squeezed out by extruding and releasing multiple times, so that the purpose of improving the compaction degree of the garbage is achieved, and meanwhile, the frequency and the compression stroke of the compressed garbage are adjusted. In addition, the weight of the garbage in a compression box is displayed in real time, so that the garbage treatment transferring process is optimized, the transferring safety is guaranteed, and the transferring cost is saved.

Description

technical field [0001] The invention relates to the field of garbage compression, in particular to an electro-hydraulic system and method for improving the compaction degree of garbage. Background technique [0002] At present, the compression mechanism and feeding mechanism of domestic garbage compression are working modes controlled by their own independent fixed mode. The compression mechanism is to stop and hold the pressure for a period of time after the compression is in place, and then retract, and the compression cycle cannot be automatically performed according to the amount of garbage in the compression box. Adjustment. Because the garbage is messy and disorderly, the garbage contains a lot of small spaces, and the small spaces are filled with air and moisture. The essence of garbage compression is to squeeze out the air and moisture in the space. In this working mode, when there is a lot of garbage in the compression chamber, although the compression mechanism ca...

Problems solved by technology

In this working mode, when there is a lot of garbage in the compression chamber, although the compression mechanism can give the garbage a strong compression force, it is also easy to block the space discharge channel, resulting in the air and water in the space not being discharged, so the compression effect is greatly improved. The phenomenon of garbage rebound is serious; when the amount of garbage is small, the compression mechanism has almost no compression force on the garbage because the loose garbage is not full of the compression chamber. If the fixed compression mode is adopted, the compression efficiency at this stage will be low

At the same time, the amount of garbage in the compression box cannot be notified to the operator in real time, resulting in insufficient or overloaded garbage in the compression box

If the amount of garbage is insufficient, the capacity of the transfer vehicle will be wasted, and the cost of transfer will increase. If the amount of garbage is overloaded, the transfer vehicle will be overloaded, which will endanger public safety.
