Description

Technical Field

[0001] The utility model relates to the technical field of coal dust collectors, in particular to a novel high-efficiency and energy-saving coal dust collector. Background Art

[0002] Pulverized coal industrial boilers are new coal-fired industrial boilers centered around pulverized coal combustion technology. Pulverized coal, ground to a 200-mesh fineness, fully removes impurities during the grinding process. The fine particle size of the coal makes it easy to ignite, and its high volatile content improves the burnout rate. The low ash content reduces the dust collection load. Currently, the disposal of fly ash collected by bag filters after burnout in high-efficiency pulverized coal industrial boiler systems remains a challenge. Previously, ash was manually discharged from the dust collection hopper using ash hopper trucks. However, this method easily creates dust and is difficult to centrally store and dispose of, often leading to secondary pollution. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a new type of high-efficiency and energy-saving coal powder collector.

[0008] The above technical solution allows collected pulverized coal to be fed into two feed ports, where it falls into the dust collector for dust removal. A rotating motor then drives the spiral blades, transferring the pulverized coal to the discharge port, completing the dust removal process. The combination of the two dust collectors and the rotating shaft ensures efficient dust removal, improving operational efficiency while minimizing dust emissions.

[0009] As a further improvement of the above solution, the conveying structure includes a fan, a fan blade is provided inside the fan, a conveying pipe is provided at the right end of the fan, and a through hole is opened at the top of the conveying pipe.

[0010] As a further improvement of the above solution, the conveying pipe is arranged at the bottom of the dust collector, and there are two discharge ports, and the two discharge ports are both inserted into the inside of the two through holes.

[0011] Through the above technical solution, the pulverized coal that has been dusted flows into the interior of the conveying pipe through the through hole, and the fan is started to rotate the fan blades, thereby blowing the pulverized coal into the conveying pipe to ensure that the boiler is clean and environmentally friendly.

[0012] As a further improvement of the above solution, the discharge structure includes an ash collecting tower, and an ash discharge valve is fixedly connected to the bottom of the ash collecting tower.

[0013] As a further improvement of the above solution, the ash collecting tower is arranged at the right end of the conveying pipe.

[0016] This utility model utilizes a dust collector, a rotating motor, spiral blades, and a discharge port. Collected coal dust is fed into the two feed ports, where it falls into the dust collector for dust removal. The rotating motor then rotates the spiral blades, transferring the coal dust to the discharge port, completing the dust removal process. The coordination of the two dust collectors and the rotating shaft allows for efficient dust removal, improving work efficiency while minimizing the risk of dust flying.

[0017] The utility model is provided with a fan, a conveying pipe, and a through hole. The dust-removed pulverized coal flows into the conveying pipe through the through hole.
