Problems solved by technology
[0002] The coal feeding device of the traditional chain row boiler is a ram-type structure. An electric ram is installed on the upper part of the coal hopper to control the amount of coal fed. As low as possible, it is easy to damage the equipment, and it needs a high-power high-speed blower to support combustion, which consumes a lot of power, wastes fuel, and pollutes the environment

The invention discloses an energy-saving coal supply device for a boiler. The device comprises a shell, wherein a water tank is arranged beside a gate on the upper part of the shell; the water tank is communicated with a circulating water pipe; the lower part of the circulating water pipe is provided with a shower head; a roller is arranged below a coal gate; a coal falling port of the roller is provided with a vibrating screen; one end of the vibrating screen is hinged with a bracket on a rear sealing plate of the shell and the other end of the vibrating screen is hinged with a connecting rod on the roller; and a fire grate and a transmission mechanism are arranged on the lower part of the shell. The device has a compact structure, can hierarchically supply coal in a stepless mode, has high coal seam air permeability, can effectively improve the coal combustion efficiency and reduce smoke dust, and contributes to protecting the environment and prolonging the service life of the equipment.
Description
technical field [0001] The invention relates to an energy-saving device, in particular to a boiler energy-saving coal feeding device. Background technique [0002] The coal feeding device of the traditional chain row boiler is a ram-type structure. An electric ram is installed on the upper part of the coal hopper to control the amount of coal fed. The efficiency is as low as possible, the equipment is easy to be damaged, and a high-power high-speed blower is required to support combustion, which consumes a lot of power, wastes fuel, and pollutes the environment. Contents of the invention [0003] In order to overcome the defects of the above-mentioned prior art, the object of the present invention is to provide a boiler energy-saving coal feeding device, which has high combustion efficiency, can reduce dust and reduce pollution. [0004] For achieving above-mentioned purpose, technical scheme of the present invention is as follows: [0005] The boiler energy-saving coal ...
