Automatic coal feeding boiler

Abstract

The invention discloses an automatic coal feeding boiler. The automatic coal feeding boiler comprises a water tank, a combustion chamber, a fire grate, a chimney, a coal inlet, a coal pipe, a coal bucket, a coal reside port, a filter net, a first supporting plate, a second supporting plate, a supporting frame, a sliding groove, an electric valve, an inductor, a tension spring and a controller. The combustion chamber is arranged at the bottom in the water tank. The side portion of the combustion chamber is flush with the side portion of the water tank. The bottom of the combustion chamber is flush with the bottom of the water tank, and the bottom of the combustion chamber is in opening design. The horizontally-arranged fire grate is arranged in the combustion chamber in a sliding manner. The upper portion of the combustion chamber communicates with the chimney extending out of the water tank. The coal inlet is formed in the right side portion of the combustion chamber. The outer end of the coal inlet communicates with the coal bucket through the coal pipe. The coal residue port is formed in the left side portion of the combustion chamber. Compared with the prior art, fire coal can be automatically added in the boiler, the labor intensity of workers is reduced, the work performance of the boiler is improved, and the heat utilization rate of the boiler is increased.

Description

【Technical field】 [0001] The invention relates to the technical field of boilers, in particular to an automatic coal feeding boiler. 【Background technique】 [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. The original meaning of the pot refers to the water container heated on the fire, and the furnace refers to the place where fuel is burned. The boiler includes two 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 life, and can also be converted into mechanical energy through a steam power device, or converted into electrical energy through a generator. Boilers that provide hot water are called hot water boilers, which are mainly used in daily life...

AI Technical Summary

Problems solved by technology

Boilers that generate steam are called steam boilers, often referred to as boilers for short, and are mostly used in thermal power stations, ships, locomotives, and industrial and mining enterprises. The existing coal-fired boilers are loaded with coal by workers using shovels to shovel coal from the coal inlet for combustion. Indoors, this is time-consuming and labor-intensive, and the labor intensity of workers is high. Moreover, opening the coal inlet to feed coal into the combustion chamber will cause a large amount of heat to flow out from the coal inlet, resulting in waste of heat. In addition, the smoke generated by the existing coal-fired boiler The gas is directly discharged into the atmosphere from the straight chimney, resulting in a short heat exchange time between the heat and the water in the boiler, and a small area, which reduces the heat utilization rate of the boiler.
