Brief Introduction

Located in Yixing, an advanced and beautiful city of Jiangsu Province, China, Longdai Co., Ltd is a processing equipment supplier of petrochemical industry specialized in environmental processing &integrating independent research and development, design, general contracting, environmental protection equipment manufacturing, and relevant material supply.

Description

Structures used for sludge thickening. Generally, it adopts a vertical flow or radial flow shape. It can be divided into intermittent operation and continuous operation. The former is mainly used in small sewage treatment plants or sewage treatment plants of industrial enterprises, and the latter is used in large and medium sewage treatment plants. The form of the continuous gravity thickening tank is the same as the radial flow sedimentation tank. It can be divided into three types: scraper and sludge mixing device, without scraper, and multi-layer thickener (with scraper).

Parameters

Structure and Working Principle

The thickening tank has two operation modes: continuous and intermittent. Continuous operation refers to continuous mud feeding and continuous mud discharging, which is relatively easy to achieve in larger sewage treatment plants. Small sewage treatment plants generally can only intermittently enter and discharge sludge, because the primary sedimentation tank can only be operated intermittently. Continuous operation can keep the sludge layer stable, which is more beneficial to the concentration effect. Treatment plants that cannot be operated continuously should "frequently enter and arrange" so that the operation tends to be continuous as much as possible. Of course, this depends to a large extent on the sludge discharge operation of the primary sedimentation tank. When it is not possible to "drain frequently", at least ensure timely discharge of sludge, and each discharge must not be excessive, otherwise the sludge discharge speed will exceed the thickening speed, which will make the sludge discharged and destroy the sludge layer.

Main Features

1. The inlet and outlet troughs around the sedimentation tank are designed with side-sections to ensure uniform water distribution and outflow around the sedimentation tank.

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

3. When φ≤40m, a single-sided straw is used, and if φ>40m, a double-sided straw is used.

4. The sludge suction pipe uses a horizontal perforated pipe to discharge the sludge, which does not interfere with the density flow in the tank and ensures the stability of the water.

5. sludge suction on the cone-shaped sludge suction pipe is uniquely designed and adopts variable hole pitch, from inside to outside, from small to large, to ensure balanced sludge suction at the bottom of the whole pond, increase sludge suction concentration, and save sludge backflow power.

6. There are two ways of skimming: plate skimming and tube skimming (the former is conventionally used).

7. The equipment is easy to operate, and the operation of the equipment can be directly controlled locally/remotely.
