The mud water separation equipment designed and manufactured by Guanneng Solid Control can be used for mud water balance shield tunneling and pipe jacking construction projects. The mud from shield tunneling and pipe jacking construction is pumped into the crown energy mud water separation equipment, and then separated by vibrating screens, sand removers, mud removers, and horizontal screw centrifuges, which can meet the continued use of the mud. If the mud needs to be discharged or the extremely small particles in the mud need to be removed, and the aged and discarded mud needs to be treated, the large conversion horizontal screw centrifuge from Guanneng Solid Control Company can be used in conjunction with a chemical dosing device to configure a flocculant for the dewatering treatment of the mud, discharging dry and clean water or water for reuse.

Shield tunneling and jacking mud dewatering centrifuge

Various sizes of horizontal screw centrifuges designed and manufactured by Guanneng Company are used for dewatering of shield tunneling slurry. The construction of shield tunneling requires a large amount of slurry, usually mixed with large rotary drum horizontal screw centrifuges. The commonly matched ones are the Crown Energy 550mm series horizontal screw centrifuge GNLW553C-VFD and the 760mm series horizontal screw centrifuge GNLW764A-VFD. Guanneng Company can also provide a complete set of containerized modular horizontal screw centrifuge systems according to customer needs. The bottom container usually houses a chemical dosing device, while the top container houses a decanter centrifuge. It can be stacked and used on site to save space. The modular design of containers also allows users to easily transfer between different construction sites.

Characteristics of Guanneng shield tunneling and pipe jacking mud water separation equipment:

• Guanneng Company is a company capable of manufacturing a complete set of mud water separation equipment and large conversion horizontal screw centrifuges. All core devices are independently developed and manufactured to make the system configuration more reasonable and stable.
• Usually, a 4-stage separation process is used, including a vibrating screen, a sand remover, a mud remover, and a centrifuge, to make the mud separation cleaner.
• Compact structure, modular design, easy to install and move on site.
• An international marketing service network can meet the fast service needs of domestic and foreign customers.
• The vibrating screen has high excitation force and separation efficiency
• The horizontal spiral centrifuge has a high degree of automation, saves manpower, and improves comprehensive processing efficiency.
• According to different customer needs, customized design can also be carried out based on the customer's on-site situation.

The main process of Guanneng shield tunneling and pipe jacking mud water separation equipment is as follows:

• The first stage coarse sieve is used to screen large rock particles in shield tunneling slurry.
• The mud centrifugal pump sends the mud that has passed through the primary screening into the desanding cyclone.
• The solid phase separated by the desanding cyclone falls into the bottom supporting dewatering vibrating screen for dewatering treatment.
• Another mud centrifugal pump pumps the mud to the desilting cyclone for separating solids larger than 20 microns.
• The solid separated by the desilting cyclone also falls into the bottom dewatering vibrating screen for dewatering treatment.
• Without the addition of chemical agents, a centrifuge can mechanically separate solid particles of 2-5 microns.
• Ultra fine particles can be fully separated through the cooperation of a crown energy centrifuge and a chemical dosing device to obtain clean water for recycling or to meet emission requirements.
