Blower device for air blowing coal stove

Abstract

The invention discloses a blower device for an air blowing coal stove. The blower device comprises a third-stage blowing hose, a second-stage blowing hose, a center supporting rod, a bottom supporting frame, a self-locking type first-stage ventilation cavity and a wind wing type strong air blower. The wind wing type strong air blower is mounted on the right side of the self-locking type first-stage ventilating cavity through hexagon bolts in an airtight manner, and a first-stage air blowing pipe is arranged on the right side of the self-locking type first-stage ventilating cavity. The center supporting rod is mounted in the middle inside the first-stage air blowing pipe. A spiral air blowing guide plate is arranged on the peripheral outer wall of the center supporting rod. A third-stage ventilating cavity and a second-stage ventilating cavity are formed in the top of the first-stage air blowing pipe. The bottom supporting frame is arranged at the bottom of the first-stage air blowing pipe. Through the cooperation of the self-locking type first-stage ventilating cavity, the second-stage ventilating cavity and the third-stage ventilating cavity, coal can obtain enough oxygen at all the combustion stages and different combustion positions, and combustion is more complete; and resources are saved, emissions of harmful gas are reduced, and environmental pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of blast coal furnaces, in particular to a blast device for blast coal furnaces. Background technique [0002] In the early days of liberation, the simplest coal stove was made of bricks, square and columnar, with a chimney connected to blow the smoke to the outside. The iron coal stove was more commonly used, cylindrical or gourd-shaped, consisting of a furnace bottom and a furnace body. It consists of two parts. The furnace body is hollow and used for charging coal. There is a damper in the front and a flue connecting the chimney in the back. Coal stoves are classified according to the use of coal and its products: ordinary coal stoves, coal pellet stoves, coal cake stoves and honeycomb coal stoves. Ordinary coal furnaces directly use coal as fuel, and coal pellet furnaces burn coal balls made of coal powder. Coal cakes are made of coal and have small holes on them. Instead, the little door in the front ...

Problems solved by technology

[0003] However, the design of the traditional coal stove is unreasonable, the effect of getting angry is not good, and the heat dissipation is serious. Because of the serious problem of ventilation, when the coal is burned, the combustion degree is low and harmful gases are produced, such as carbon monoxide. If there is too much carbon monoxide in the room, it will cause suffocation and death of people or animals. Need to find an effective blowing way to solve this serious problem
