Description

Slag screening device for household garbage incineration power plant Technical Field The utility model relates to the technical field of garbage incineration treatment, in particular to a slag screening device for a household garbage incineration power plant. Background Slag generated in the incineration process of household garbage has complex components, contains a large amount of recoverable substances such as metal, glass and ceramic and nonflammable ash, and is screened by adopting a rotary screen and other devices in the pretreatment and metal recovery stages of the slag, so that large materials (such as coarse stones, slag, plastic bags, cloth and the like) and fine particles are separated; The existing drum screen is cleaned by rotating brushes or rotating leather strips, but part of foreign matters are blocked in the screen holes, so that thorough cleaning is difficult to achieve in the mode. Therefore, the design of the screening device can realize normal screening of slag and can conveniently and effectively clean the screen holes. Disclosure of utility model The utility model aims to solve the defect that part of foreign matters are blocked in sieve holes in the prior art, and provides a slag screening device for a household garbage incineration power plant. In order to achieve the above purpose, the present utility model adopts the following technical scheme: the slag screening device for the household garbage incineration power plant comprises a bracket and a roller rotatably arranged at the top of the bracket, wherein a plurality of groups of screen holes are formed in the surface of the roller; The driving mechanism is used for driving the roller to roll and is arranged at the top of the bracket; The cleaning mechanism is used for cleaning foreign matters clamped inside the sieve holes and comprises a plurality of cleaning rods, a plurality of mounting frames are fixedly arranged at the top of the support, the same sliding plate is arranged in the mounting frames in a sliding mode, the cleaning rods are fixedly arranged at the bottom of the sliding plate, and the cleaning rods are matched with a plurality of sieve holes of the same group respectively.
