Sewage is carrying to the filter pressing device in-process, adds the medicine through charge device, and sewage after adding the medicine gets into the pressure filter, carries out the filter-pressing through the pressure filter, and the mud cake that the filter-pressing produced is assisted slag discharging device through the third and is transported to main slag discharging device, carries to ground dregs pond by the slag discharging device, and the clear water of production is carried to ground clear water pond through clean water pump and is retrieved reserve. The whole process of the muck treatment is automatically controlled by the controller.
It should be noted that, in the working process of the processing system, when the front end of the material receiving belt conveyor is tunneled along with the shield machine, a section of fixed support is supplemented at the position vacated by the rear end every time the material receiving belt conveyor moves a fixed distance.
In addition, when the shield tunneling machine tunnels, the muck conveying device, the screening device, the dewatering device, and the filter pressing device move in the direction in which the shield tunneling machine tunnels.
The processing system has the advantages of reasonable structure, compact layout, realization of real-time processing of underground muck, no need of occupying ground operation space, low operation cost and no environmental pollution. The continuous output of the muck is completed through automatic control of the control device, the whole automation degree is high, the manual investment is reduced, the operation is simple, the safety and the reliability are high, and the stability is good.
The above-described embodiments are intended to illustrate rather than to limit the invention, and any modifications and variations of the present invention are possible within the spirit and scope of the claims.
