TECHNICAL FIELD

[0001] The utility model relates to the technical field of material accumulation self-cleaning, especially to a material accumulation self-cleaning type unloading centrifuge. BACKGROUND

[0002] Centrifugal unloading refers to the unloading mode that the material particles in the hopper of the bucket elevator move to the outer edge of the hopper and are thrown out under the action of centrifugal force greater than gravity, and the traditional centrifugal unloading machine lacks automatic cleaning of accumulated material, and manual cleaning is adopted, which reduces the working efficiency of the device.

The cleaning structure is fixedly arranged in the main body structure, and the dehydration structure is fixedly arranged below the main body structure. After solid-liquid separation by the main body structure, the dehydration structure can be driven by the power on the main body structure to re-dehydrate the solid objects, thereby enhancing the solid-liquid separation effect. After use of the equipment, the first motor is controlled to drive the shielding assembly to correspond to the scraper, and then the hanging plate is inserted into the outer rotating drum to scrape off the solid objects adhered to the spiral blades of the inner rotating stock.
