Biological Sludge Scraper Company

Scraper Concentrator Center Drive Scraper Suction Mud Machine

Purpose:
The WNG type scraper is used in the gravity sludge concentration tank of sewage treatment plants to scrape the concentrated sludge to the central mud pit at the bottom of the tank for further sludge dewatering treatment.
Characteristics:
1. Less transmission links, high mechanical efficiency, and compact structure;
2. An over torque protection mechanism can be installed as needed to automatically alarm and shut down the equipment when the torque reaches the set value, ensuring safe and reliable operation of the equipment;
3. The spindle adopts a rigid tubular structure, and there are no bearings at the bottom of the pool, which solves the maintenance work of the pool bottom in extremely harsh environments.

Scraper Concentrator Center Drive Scraper Suction Mud Machine

Construction and working process:
The scraper is a suspended center drive, as shown in Figure 1, consisting of a vertical reducer with an electric motor, a rotary bearing with external teeth, a main shaft, a scraper arm, a scraper, a concentration grid, a steady flow cylinder, a control cabinet, etc.
The scraper arm rotates around the central axis of the pool under the drive of the transmission device. The scraper on the scraper arm pushes the sludge deposited at the bottom of the pool from the outside to the inside towards the mud collection pit at the center of the pool. During operation, due to unexpected reasons such as foreign objects jamming or excessive mud accumulation, the transmission is over twisted. When the torque reaches the set value, the over twist protection mechanism will act, cut off the power supply, and automatically alarm and stop the machine.
