Muck solid-liquid separation device

Abstract

The invention relates to a muck solid-liquid separation device which is characterized by comprising a supporting platform, a solid-liquid separation tank, a protection plate, a centrifugal machine and a drain valve; the supporting platform comprises a mounting base and a supporting column, and the supporting column and the mounting base are fixed in a welding mode; the protection plate is located above the supporting platform and comprise a first protection plate and a second protection plate, and screw holes are symmetrically formed in the top end of the first protection plate and the top end of the second protection plate; the solid-liquid separation tank is arranged in the protection plate and comprises a tank body and a cover body; the centrifugal machine is positioned at the front end of the solid-liquid separation tank and is fixed on a steel plate erected between a second supporting column and a fourth supporting column; and the drain valve is positioned at the bottom end of the solid-liquid separation tank and comprises a liquid drain valve, a solid drain valve and a liquid medicine injection valve.

Description

technical field [0001] The invention relates to a tunnel dregs treatment device, in particular to a dregs solid-liquid separation device. Background technique [0002] With the continuous development of urban rail transit, more and more tunnels need to be built. Tunnel construction using the shield method will produce a large amount of shield dregs. During the construction process, the seepage of the tunnel ground and construction water will enter the shield dregs, making the shield dregs have a large water content and become a thin mud state, which is difficult to transport. Manual processing is quite difficult and consumes a lot of manpower and material resources. [0003] At present, the solid-liquid treatment of shield dregs mainly includes chemical dehydration method and natural precipitation method. The chemical dehydration method uses a large amount of chemicals and has low treatment efficiency. The natural precipitation method is simple, easy to implement, low in ...

Problems solved by technology

The mud-water separation device, by increasing the left chamber and the right chamber, slows down the flow rate of the water flow, slowly rises through flood irrigation and finally discharges from the outlet pipe, which ensures the filtering effect of the device on the sludge in the sewage and solves the problem of The cleaning effect of the existing device is not ideal, and the noise is extremely high, but it has the disadvantages of long time consumption and high operating cost
