Abstract

The invention provides a centrifugal sludge dewatering device based on ultrasonic. The centrifugal sludge dewatering device comprises a shell, a base, a centrifugal cylinder, a stirring mechanism, anultrasonic generator, a first drive motor and a second drive motor, wherein the shell is of a cylindrical structure and the shell is buckled onto the base in an inverted manner that the bottom faces upwards; the centrifugal cylinder is coaxially arranged inside the shell and the centrifugal cylinder is rotatably fixedly arranged on the base; the second drive motor drives the centrifugal cylinder to rotate; the ultrasonic generator is arranged on the inner side of the bottom of the shell and the transmitting direction of the ultrasonic generator directly faces the cylinder opening of the centrifugal cylinder; and the stirring mechanism comprises an upper drive shaft, an installation box, two third drive motors, two transverse stirring shafts and a longitudinal stirring shaft. Sufficient dewatering can be carried out on sludge, a specified moisture content standard can be reached after sludge dewatering treatment, and further sterilization treatment is carried out by using ultrasonic inthe dewatering process, so that the device is beneficial to environmental protection.

Description

technical field

[0001] The invention relates to sewage treatment equipment, in particular to an ultrasonic-based centrifugal sludge dewatering device. Background technique

[0002] With the intensification of human production activities, a large amount of sewage will be produced in the production activities, and flocculation and sedimentation are required to form sludge in the process of sewage treatment. Since the sludge contains more than 95% of water, in order to protect the environment, it is necessary to Dehydration of sludge, the existing sludge dewatering equipment has the following defects: Existing sludge dewatering equipment in press dehydration, centrifugal dehydration and other methods, among them, although press dehydration can be more fully dehydrated, but the structure is complex, the equipment It is bulky and expensive to use, which is not conducive to miniaturized sludge treatment. Although the existing centrifugal dewatering is beneficial to miniaturized sl...
