Rotary cleanable sludge granulator

Abstract

A rotary cleanable sludge granulator can well improve the working efficiency of granulation without affecting the cleaning of a filter cylinder, so the service life of the filter cylinder is effectively prolonged. The rotary cleanable sludge granulator comprises a bottom plate, a cylindrical shell is arranged above the bottom plate, the sidewall of the lower part of the cylindrical shell is provided with a concave portion, the filter cylinder sleeves the outer circle of the cylindrical shell, a scraper plate sleeves the filter cylinder, a cleaning plate is arranged in the concave portion, a support disc is arranged between the cylindrical shell and the bottom plate, first springs are connected between the support disc and the bottom plate, and a rotating shaft is arranged in the cylindrical shell; and a top plate is arranged at the upper end of the cylindrical shell, a second spring is connected between a cover plate and a support plate, a pin shaft is inserted in the cover plate, thepin shaft and the rotating shaft are arranged eccentrically, the rotating shaft can drive the filter cylinder to rotate through the pin shaft in order to stretch the second spring, and after the rotating shaft continuously rotates for a certain time, the filter cylinder reversely rotates under the action of the second spring in order to restore the filter cylinder to the initial state. The granulator has the advantages of novel conception and ingenious structure.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a rotary cleanable sludge granulation device. Background technique [0002] In order to reduce a large amount of energy consumption in the sludge drying process and meet the requirements of conservation and environmental protection, mechanical pretreatment is carried out before drying, and granulation of sludge is often used. Due to the boring contact area with the outside world after granulation Increase, can effectively improve the drying efficiency. [0003] However, since the sludge often contains a large amount of impurities, such as stones, the granulation function is usually performed through a screen during the granulation process, and the screen may be blocked after a long time of work, resulting in a decrease in granulation efficiency and possible Affect the life of the screen, the existing equipment is through regular maintenance and cleaning of the screen, w...
