Self-cleaning high-efficiency sludge granulator

Abstract

The invention relates to a self-cleaning high-efficiency sludge granulator, which well improves the working efficiency of granulation, cleans the filter cartridge without affecting the working, and effectively improves the service life of the filter cartridge. The technical solution comprises a bottom plate, a cylinder body is arranged on the bottom plate, the lower side wall of the cylinder body is provided with a recess, the non-recessed part of the side wall of the cylinder body is provided with a through groove, a filter cartridge is sleeved on that outer circle of the cylinder body, a scraper plate is sleeved on that outer circle of the filter cartridge, a sweep plate is arranged in that recess, a support plate is arrange between that cylinder body and the bottom plate, the scraper plate and the sweep plate can move up and down together with the support plate, a spring is connected between the support plate and the bottom plate, a rotating shaft is arranged in the cylinder body, a top plate is arranged at the upper end of the cylinder body, a cover plate is arranged at the upper end of the filter plate, a through hole is arranged at the center of the cover plate, a push rod is arranged on the side wall of the through hole, and a push plate on the outer edge of the rotating shaft. The invention has novel conception and ingenious structure.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a self-cleaning high-efficiency sludge granulator. 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 scre...
