Driving type pump suction dredger, used for advection sedimentation tank of sewage treatment plant, scrapes the sludge settled on the bottom of the tank to the pump suction port, sucks the mud while driving, and then discharges the sludge out of the tank. So that the sludge can be refluxed or concentrated for dehydration.
1. Simple structure and light weight: Thanks to the truss structure, the weight is greatly reduced compared with the traditional mechanism.
2. Simple and convenient maintenance and low running cost.
3. A new type of transmission mechanism. The reducer uses a shaft-mounted reducer, which is easy to install, simple and compact in structure, and highly efficient.
4. The electrical components are all outdoor, safe and reliable, and can be controlled randomly or remotely.
5. According to the needs of users, the walking wheels can be rubber wheels, nylon wheels, steel wheels. It can be made to user-specific sizes and parts in contact with water can also be made of stainless steel.
Fourth, the structure and engineering process
As shown in Figure -1, the traveling-pump suction dredger is composed of a working bridge, a suction pipe, a dredging pipe, a submerged sludge pump, a driving mechanism, and an electrical box. This equipment is supported by a four-point supporting walking beam across the advection sedimentation tank, driven bilaterally. Steel rails are laid on both sides of the tank, running from one end of the tank to the other end of the tank, sucking mud while running, hitting stroke control, and returning to the original Ground; hit the stroke switch, stop; stop time is controlled by the time relay (1 minute-12 hours) to complete a working cycle. The civil requirements are shown in Figure-2, and the technical parameters and specifications are shown in Tables 1 and 2.
