Description
Technical Field
[0001] The present invention relates to the technical field of dry slag conveyors, and more particularly to an anti-miscontact system for a dry slag conveyor. Background Art
[0002] A boiler is an energy conversion device. The energy input into the boiler includes the chemical energy in fuel and electric energy. The boiler outputs steam, high-temperature water or organic heat carriers with a certain amount of heat energy. The original meaning of "pot" refers to a water container heated over fire, and "furnace" refers to a place for burning fuel. The boiler includes two main parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's livelihood, or can be converted into mechanical energy through a steam power device, or the mechanical energy can be further converted into electric energy through a generator. A boiler that provides hot water is called a hot water boiler, which is mainly used for life and has a small amount of application in industrial production. Since China is rich in coal resources, coal-fired boilers are still widely used in China;
[0003] The dry slag conveyor, which is the core equipment of the boiler slag discharge system of a coal-fired thermal power unit, is used to cool and convey the hot slag discharged from the boiler. A slag crusher is arranged below the head of the dry slag conveyor, and the furnace slag enters the slag bin after being crushed by the slag crusher. A rotary level switch is installed in the feeding hopper at the head of the dry slag conveyor belt. When the slag crusher trips or a large foreign object blocks the feeding hopper at the head of the dry slag conveyor belt, the rotary level switch will give an alarm and interlock the operation stop of the dry slag conveyor belt; thus preventing the risk of the dry slag conveyor being blocked due to the accumulation of ash slag, which may affect the operation of the thermal power unit. Due to factors such as high temperature and large dust in the field, the single level switch is prone to misoperation risks; during the process of workers cleaning the slag bin, there is a problem that dust fills the slag bin, and a small amount of ash slag is not crushed, resulting in the inability to carry out the next step of cleaning.
