Clarifying tank scraper center drive

Clarifying tank scraper center drive

Central transmission scraper suction machine, central transmission single tube suction machine: using the water level difference, the sludge at the bottom of the tank is sucked into the sludge discharge tank, and discharged through the siphon tube into the central cylinder sludge discharge pipe. At the same time, the floating slag in the pool is collected by a scraper and discharged outside the pool through a slag discharge hopper.

1. The inlet groove adopts a design of variable cross-section, variable flow rate, and variable head, ensuring the uniformity of the inlet water;

2. Cone shaped suction pipe with variable aperture and spacing suction holes, allowing for uniform and proportional collection of sludge at the bottom of the entire pool, achieving a one-time suction of sludge;

3. Novel structure, lightweight, uniform sludge discharge, stable operation, overload alarm, operation;

4. High surface load, low power consumption, easy maintenance, and low operating costs;

5. Electrical control can be customized according to customer requirements, and customers can choose control features such as manual, semi-automatic, PLC control, and remote communication.

Thus, the scraping mechanism is driven to rotate, scraping the sludge at the bottom of the sedimentation tank. Then, through the suction mechanism, the sludge is sucked into the collection tank of the sludge collection mechanism, and then through the discharge mechanism, using the siphon principle, the sludge is discharged into the sedimentation tank through the discharge pipe. The floating slag on the upper part of the sedimentation tank is scraped into the sludge hopper by the scraper plate of the slag automatic flushing mechanism, which follows the rotation of the scraper mechanism. The floating slag is then washed into the discharge pipe and flushed out of the sedimentation tank through the cleaning device installed on the inner wall of the sludge hopper. Dirt scraper suction machine.

During the operation of the walking motor, each motor plays its own role and does not interfere with each other. The bottom of the scraper is equipped with a underwater walking wheel structure to ensure smooth operation. The two walking motors use synchronous motors to ensure consistent and stable walking on both sides.

Features: 1. The inlet and outlet channels around the sedimentation tank are designed with edge sections, ensuring uniform water distribution and outflow around the sedimentation tank.

2. The driving device adopts a combination of helical gear reducer and worm gear reducer to ensure output torque and speed, with high transmission effect; The reducer is equipped with an over force torque protection device, ensuring safe and reliable operation;

3. When Φ ≤ 40m, use a single-sided straw, Φ>40m， Then use double-sided straws;

4. The suction pipe discharges sludge in a horizontal perforated manner, which does not interfere with the gravity flow in the pool and ensures the stability of the effluent.

5. The suction port on the conical suction pipe is designed with variable hole spacing, from inside to outside, from small to large, to ensure balanced suction of sludge on the entire bottom of the tank, increase suction concentration, and save sludge reflux power;

6. There are two types of skimming methods: plate skimming and tube skimming;

7. The equipment is easy to operate and can be directly controlled locally/remotely for its operation;

1. Walking: One end of the main beam in the upper part of the pool is equipped with a transmission device, and the other end is connected to the central support in the center of the pool and runs in a circular motion around it. The transmission device is a planetary cycloidal pinwheel reducer that drives the walking wheel to rotate through chain transmission, thereby driving the beam to rotate.

2. Power supply: The collector device consists of a collector ring and corresponding electric brushes. The power cables and all control circuit wires are all routed through the bottom transmission conduit of the pool, passing through the hollow part at the bottom of the central support and connected to the collector ring, passing through the electric brush to the terminal block, and finally reaching the distribution box to meet the power supply requirements.

3. Mud discharge device: The mud collection tank is located at the bottom of the center of the pool. The scraper continuously collects the sludge in the sludge collection tank and discharges it outside the tank through the sludge discharge pipe.

4. Slag discharge device: The slag collection tank is located on one side of the tank body, and the bracket is fixed to the tank body by expansion bolts. The scraper plate is installed at a certain angle with the driving beam and fixed on the hanger. When the main beam moves, the surface floating slag is collected along the scraper plate towards the direction of the slag collection tank, and scraped into the slag collection tank by the scraper rake plate. It is discharged outside the tank through the slag discharge pipe at the bottom of the slag collection tank.
