Detailed introduction

use

The central drive single-pipe dredger is used in large-scale circular sedimentation tanks in urban sewage treatment plants and industrial wastewater treatment, especially in secondary sedimentation tanks, to remove sludge that settles at the bottom of the pond and to remove scum on the surface of the pond. This series of mud suction machine is not only suitable for the second settling tank with perimeter inflow and outflow, but also for the second settling tank with perimeter inflow and outflow.

structure

The following components of the central drive single-tube dredger:

2 中心驱动系统、 3 中心管及支承座、 4 中心竖架、 5 密封圆筒、 6 吸泥管、 7 排渣槽及撇渣装置、 8 支撑桁架及刮泥板、 9 溢流堰板和挡渣板、 10 挡水裙板、 11 导流筒。 1 working bridge, 2 center drive system, 3 center pipe and support seat, 4 center stand, 5 sealed cylinder, 6 mud suction pipe, 7 slag discharge tank and slag skimming device, 8 support truss and scraper, 9 overflow Weir plate and slag shield, 10 water skirt, 11 deflector.

working principle

When the suction machine is running in the surrounding secondary water sink tank, the raw water to be deposited enters through the water distribution hole at the bottom of the peripheral annular groove, and flows at the bottom of the pond to the center of the pond in a gravity flow state, and the sludge is under gravity. Settling under the action, a thick layer of mud is formed at the bottom of the entire sedimentation tank, and the supernatant flows upward and returns to the surrounding overflow weir for discharge. The driving device drives the suction pipe to slowly rotate at the bottom of the sedimentation tank. Because the suction pipe, the central sealed cylinder and the sludge discharge pipe form a sealed discharge channel, the bottom sludge is sucked by the difference between the internal and external liquid levels. The tube sucks in and flows out of the pond from the sludge discharge channel. The sleeve valve controls the liquid level difference between the inside and outside of the sedimentation tank, thereby controlling the sludge discharge. At the same time, the scum on the pool surface is scraped by the skimmer device to the slag discharge tank, and the heavy mud that is difficult to be sucked by the suction pipe at the bottom of the pool is scraped by the scraper to the central mud hopper and discharged from the heavy mud discharge pipe.

20%~30% ,从而大幅度提高生化反应池效率和污泥脱水效率,减小池容,降低工程造价,同时减小日常运行耗电费用。 The central drive single-tube dredger is designed based on hydraulic theory and the characteristics of sludge at the bottom of the secondary sedimentation tank. It uses a reduced-profile shaped tube to make a suction tube, which can uniformly collect sludge in proportion to the entire bottom of the tank. In comparison, it can increase the sludge concentration by 20% to 30% , thereby greatly improving the biochemical reaction tank efficiency and sludge dewatering efficiency, reducing the tank capacity, lowering the project cost, and reducing the daily operation power consumption costs.
