Product Specification

Product Description

Operating principle

Features

1. The advantage of the device:

   1.       wide application scope

   a)       It can be used widely in sludge dewatering in many industries, such as municipal wastewater, food, beverage, slaughtering farming, printing and dyeing, petrochemical, paper-making, leather, pharmaceutical industries.

   b)      The unique principle of dehydration makes the device suitable for sludge of both high and low concentration. From 2000mg/L, sludge concentration and dewatering can be directly finished.

   c)       With the new type of structure design, the device is appropriate for all kinds of sludge, whether high or low viscosity, especially for oil sludge. The processing effect is excellent.

   2.       continuous and automatic operation

   Disc type spiral sludge dehydrator is complete automatic control, from the mud injection, dosing, to sludge eduction. With the help of the electric control cabinet, sludge feed pump and dosing devices are interlocked, without personal operation. And there’s no need to worry about the plugging. What’s more, routine maintenance is simple and it can run unattended for 24 hours.

   3.       significant cost savings

   The integration of the overall design and compact structure help to save running cost significantly. Firstly, screw squeezes at a low speed, which reduces the power consumption greatly. Secondly, the material isn’t blocked in the equipment, which saves a lot of rinse water. Thirdly, it can operate automatically with no guard for 24 hours, which greatly reduces the labor cost.

   4.       durability

   The device uses low-speed mechanical compression, with no need of large-scale roller structure. In the case of low-speed operation, there’s just a little wear and tear, and therefore, it is designed relatively light and compact. In addition, all the parts are made of high quality stainless steel, which ensures the long working life of the equipment.Application scope
