Problems solved by technology

[0004] For the above-mentioned related technologies, the inventor believes that there are following defects: the solid content and water content in the sludge are generally high, and when the sludge with high water content is processed, it takes a long time to process the sludge The moisture in the sludge is evaporated, and at the same time, the high temperature of the drying chamber needs to be maintained throughout the drying process, so it takes a lot of energy to process the same batch of sludge for a long time

Embodiment 1

[0049] The implementation principle of Embodiment 1 is: when treating sludge, transport the sludge to the feed hopper 31 at the upper end of the machine body 2, the sludge in the feed hopper 31 will enter the distribution pipe 32, and start the drive motor 131, the driving motor 131 drives the first pulley 132 to rotate, and the first pulley 132 drives the second pulley 133 to rotate through the belt 134, and can drive the distribution pipe 32 to rotate when the second pulley 133 rotates, and the distribution pipe 32 The second vertical part in will rotate directly above a plurality of centrifugal dehydration drums 6 . The material distribution pipe 32 stops above the single centrifugal dewatering cylinder 6, and the first valve 14 is opened, and the material distribution pipe 32 transports the sludge into the single centrifugal dehydration cylinder 6 to realize the sludge feeding.

Abstract

The invention relates to the technical field of sludge treatment, in particular to a sludge treatment device, which comprises a machine body sequentially provided with a feeding area, a dewatering area and a discharging area from top to bottom, wherein the dewatering area comprises a plurality of centrifugal dewatering cylinders arranged in the machine body, and a heating device is arranged in themachine body. The invention also provides a sludge treatment method which comprises the following steps: 1, firstly conveying sludge into a feeding area, distributing the sludge, and equally classifying the sludge into different parts for dehydration treatment; 2, dewatering the classified sludge through high-speed centrifugation; 3, heating the sludge during the dehydration process. When the sludge treatment device is used for treating sludge, the plurality of centrifugal dewatering cylinders can be used for dewatering the sludge at the same time, and the heating time can also be shortened and the energy is saved when the sludge is subjected to subsequent drying and heating while rotary dewatering is carried out.

Description

technical field [0001] The present application relates to the field of sludge treatment technology, in particular to a sludge treatment device and treatment method. Background technique [0002] With the construction of a large number of sewage treatment plants in my country and the continuous improvement and improvement of sewage treatment technology, sludge treatment has become an important link that must be given priority in the design and operation of sewage plants. Sludge dewatering equipment is used in municipal domestic sewage, river water, industrial sewage, etc. industry has been widely used. [0003] The most critical indicator of sludge treatment is the water content. At present, the methods of sludge treatment mainly include mechanical dehydration, thermal drying, anaerobic fermentation, incineration and so on. At present, the Chinese invention patent with the notification number CN103708690B discloses a sludge treatment equipment, including a sludge conveyor, a ...
