Special coal adding equipment and special coal adding method for fuel hot-air furnace of solar greenhouse

Abstract

The invention discloses a special automatic coal adding machine for a coal hot-air furnace of a solar greenhouse. The special automatic coal adding machine comprises a coal hopper, an upper coal conveying roll, a framework, a smoke blocking door, a lower coal conveying roll, mounted bearings, a coal conveying barrel, a belt wheel, chain wheels, roller chains, a motor, a V-shaped belt and a gearbox. The coal hopper is mounted on the top of the framework. The special automatic coal adding machine is characterized in that the upper portion of the coal hopper is in the shape of an inverted horn, the lower portion of the coal hopper is backwardly oblique, the left side and the right side of the coal hopper are vertical, and the bottom of the coal hopper is oblique; holes for mounting the upper coal conveying roll and the lower coal conveying roll are respectively formed in the middle and the lower portion of the coal hopper; two ends of the upper coal conveying roll and two ends of the lower coal conveying roll are connected with the framework by the mounted bearings; the chain wheels are respectively mounted on the upper coal conveying roll and the lower coal conveying roll, and the upper coal conveying roll and the lower coal conveying roll are connected with an output end of the gearbox by the roller chains; the belt wheel is mounted at an input end of the gearbox, and the gearbox is connected with the motor at a power output end by the V-shaped belt; the coal conveying barrel is connected to the lower portion of the coal hopper, an oblique angle which is not smaller than 40 degrees is kept between the coal conveying barrel and the horizontal plane, and the coal conveying barrel is connected with a furnace mouth of the hot-air furnace by a flange; the coal hopper is separated from the coal conveying barrel by the smoke blocking door.

Description

technical field [0001] The invention relates to a special coal feeding equipment and method for a coal-fired hot air stove in a solar greenhouse, which uses a mechanical transmission mode to realize automatic coal feeding, and belongs to the field of agricultural equipment. Background technique [0002] With the development of facility agriculture in our country, greenhouse cultivation is used more and more in winter, especially in the north. However, due to the extreme weather every year, hot blast stoves must be equipped for agricultural production operations. Xinjiang is the main coal production area in the country, and the price of coal is relatively low. Therefore, coal is the main energy source for hot blast stoves. The following problems occur during the use of hot blast stoves: [0003] 1. During the use of the hot blast stove, it is not allowed to add too much coal at one time, which will affect the combustion. It needs to be added frequently and less, which require...
