Description

Technical Field

[0001] The utility model relates to the technical field of anti-blocking devices, in particular to an anti-blocking device for a slag discharger. Background Art

[0002] A boiler is an energy conversion device. The energy input to the boiler includes chemical energy and electrical energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. The original meaning of pot refers to a water container heated on fire, and furnace refers to a place where fuel is burned. The boiler consists of two major parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production, or it can be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a servo motor. A boiler that provides hot water is called a hot water boiler, which is mainly used for life and also has a small number of applications in industrial production. A boiler that generates steam is called a steam boiler, often referred to as a boiler. The coal slag needs to be removed after long-term use.

[0003] The existing anti-blocking device for boiler circulating slag discharge equipment (publication number: CN217402580U) has at least the following disadvantages:

[0004] When the above patent is in use, a connecting plate and a fixed plate are set to cooperate with the electric push rod to drive the connecting block to move, and the brush plate is driven to move by the connecting block, so that the coal slag on the top of the filter can be removed. The above patent can only clean the coal slag on the surface of the filter. Since some coal slag particles are fine, when the filter is filtered, the small particles of coal slag are easily stuck in the mesh of the filter, causing the filter to be blocked, affecting the subsequent filtering effect.
