Sludge conveying and dewatering equipment used for sludge treatment

Abstract

The invention discloses sludge conveying and dewatering equipment used for sludge treatment. The equipment comprises a material conveying cylinder used for conveying sludge, a plurality of supportinglegs used for supporting the material conveying cylinder and a collecting box used for collecting the treated sludge; and the material conveying cylinder is provided with a material inlet hopper and aspiral material supply rod, at least one dewatering box used for dewatering treatment of the sludge and first driving member used for driving rotation of the dewatering box are arranged below the material conveying cylinder, the first driving member is fixedly arranged on the collecting box, and the dewatering box is provided with a dewatering device. According to the equipment provided by the invention, through arrangement of the above structure, the sludge can be uniformly conveyed through the material conveying cylinder, so that volume treatment of the sludge is realized, and blockage caused by a too large volume of the sludge is avoided; and at the same time, the sludge can be treated by the dewatering device, so that the sludge can be dried in a certain shape in batches, forming specifications of the sludge are substantially same, mutual adhesion of the sludge can be avoided, collection arrangement of the sludge is facilitated, and the control utilization rate of the collection container is improved.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment, in particular to a sludge feeding and dewatering device for sludge treatment. Background technique [0002] With the continuous improvement of my country's urbanization level, the construction of sewage treatment facilities has developed rapidly. There are more than 2,500 urban sewage treatment plants in my country, and the urban sewage treatment capacity has reached 122 million tons per day. In order to achieve the national emission reduction goals and water The improvement of the environment has made great contributions, but the construction and operation of the sewage plant have produced a large amount of excess sludge. [0003] Now, the public document with the publication number CN206778385U discloses a sludge forming granulator, which can shape the sludge into strips or blocks with a small volume and regular shape, so that its heating is more convenient. It is energy-saving and env...

Problems solved by technology

[0004] However, when the device molds the sludge, due to the viscosity of the sludge itself, a part of the unbroken sludge automatically sticks together as it moves, making the sludge form again, making it difficult to dry the sludge, while a part of the sludge is broken The sludge is uncertain, and the length of the fracture is different. When it is loaded into the collection container, it will reduce the space utilization of a part of the collection container.
